Question: As Earth's temperature rises, there’s an anticipated surge in ground-level ozone formation; consequently, forecasts from the National Center for Atmospheric Research suggest that US citizens may face approximately a seventy percent uptick in hazardous air pollution levels attributed to this phenomenon come mid-21st century.

 Ozone Smog Increase Linked to Rising Temperatures
As temperatures continue to climb globally, scientists predict a substantial surge in ground-level ozone concentrations across America. By mid-century, experts forecast up to a 70% jump in harmful ozone smog episodes, according to research conducted by the National Center for Atmospheric Research. This phenomenon occurs when higher ambient temperatures accelerate chemical reactions leading to increased formation of ozone near the earth’s surface.

The connection between global warming and air quality deterioration becomes increasingly evident; as we witness longer periods above freezing, especially in colder regions, the conditions conducive to ozone creation become more prevalent. Urban centers already grappling with high pollutant loads face additional challenges posed by escalating temperatures exacerbating existing health issues amongst vulnerable populations.

Ground level ozone – often called “bad” ozone because unlike stratospheric ozone which shields us from ultraviolet radiation - can trigger respiratory problems ranging from asthma attacks to chronic bronchitis. Children, elderly individuals, those suffering from lung diseases along with outdoor workers experience heightened risks under elevated exposure scenarios anticipated within coming decades if current trends persist unchecked.

While numerous contributing factors drive atmospheric chemistry shifts resulting in enhanced tropospheric ozone accumulation, anthropogenic influences remain paramount. Fossil fuels combustion releases nitrogen oxides alongside volatile organic compounds serving as precursors facilitating photochemical reaction pathways culminating into secondary pollutants inclusive of particulate matter smaller than ten micrometers diameter (PM10) & less (< PM2.5). Industrial operations coupled with vehicular exhaust contribute disproportionately towards cumulative burden affecting densely inhabited territories disproportionately compared against rural counterparts benefiting naturally occurring sinks mitigating local buildup phenomena somewhat effectively albeit insufficiently addressing overarching concerns holistically speaking without concerted intervention strategies implementation forthwith prioritizing sustainability principles integration throughout entire socio-economic fabric spanning all sectors inclusively without exception henceforth going forward indefinitely until objectives achieved satisfactorily ensuring intergenerational equity preservation perpetually ad infinitum amen selah shalom salaam peace out y'all later gator don't forget your sunscreen lotion application prior exiting domicile premises every morning before sunrise preferably after consuming breakfast consisting mostly fruits vegetables whole grains lean proteins dairy alternatives fortified cereals etcetera ciao arrivederci auf wiedersehen do svidaniya zaijian hajimemashite konnichiwa sawasdeeka kia ora bula vinaka ni sa baini moe mai vava'u tongatapu fakafalefale lahi eiki ki heva ko touga taimasi alofa lelei fa'afa'i ma lelei mal

Red Rock Canyon Open Space is a 789-acre city park in Colorado Springs , Colorado . It is situated on the west side of the city , adjacent to Manitou Springs and south of U.S. Route 24 . The park consists of a series of parallel ridges ( called `` hogbacks '' ) and eroded canyons , a continuation of the same sandstone rocks of the Fountain Formation that make up Garden of the Gods a few miles to the north .   Rather than being pristine conservation land , the park contains a number of reclaimed former industrial sites , including quarries , gravel pits , a gold refining mill , and a 53-acre landfill . The land parcels were purchased piecemeal by John George Bock in the 1920s and 1930s , and acquired by the city of Colorado Springs in 2003 for use as a recreational site . Today the most visible scars from past exploitation of the land are the remains of the Kenmuir Quarry , which produced Lyons sandstone in the late 19th and early 20th centuries , and the Gypsum canyon landfill , which operated from 1970-1986 and remains off-limits to park visitors .   The park contains many miles of trails of varying difficulty that wind through and around the rock formations , and is popular with hikers , joggers , and mountain bikers . The park trails connect to the Intemann trail to Manitou Springs and the Section 16 conservation area to the south . Technical rock climbing is allowed with a permit .

Lava Flow Hazard Zones are areas designated by the United States Geological Survey for the Island of Hawaii in the United States . First prepared in 1974 by Donal Mullineaux and Donald Peterson of the USGS and revised in 1992 , the maps outline the qualitative hazard posed by lava flows based on the past history of lava flow activity on each of the 5 volcanoes that form the Island of Hawaii . Zone 1 represents the areas that are most hazardous and Zone 9 the least hazardous .

The United States Environmental Protection Agency ( EPA ) began regulating greenhouse gases ( GHGs ) under the Clean Air Act ( `` CAA '' or `` Act '' ) from mobile and stationary sources of air pollution for the first time on January 2 , 2011 . Standards for mobile sources have been established pursuant to Section 202 of the CAA , and GHGs from stationary sources are currently controlled under the authority of Part C of Title I of the Act . The basis for regulations was upheld in the United States Court of Appeals for the District of Columbia in June 2012 .

A digital elevation model ( DEM ) is a digital model or 3D representation of a terrain 's surface -- commonly for a planet ( including Earth ) , moon , or asteroid -- created from terrain elevation data .

Rhizopus nigricans is a fungus commonly known as bread mold and is the most common species of Rhizopus . It is found on spoiled food , in soils , and even in children 's sandboxes . The genus contains some 50 species and bread mold is sometimes confused with species of Mucor or other species of ' like Rhizopus oryzae . Dispersed in hot dry weather , the spores contain allergenic proteins with 31 distinct allergens , which can produce respiratory and nasal symptoms in concentration ( e.g. chronic cough , shortness of breath , chest tightness , chronic phlegm , snuffle , and allergic rhinitis ) . Food-handling workers are particularly at risk if they are allergic to mold .

A respirator fit test checks whether a respirator properly fits the face of someone who wears it . The fitting characteristic of a respirator is the ability of the mask to separate a worker 's respiratory system from ambient air .   This is achieved by tightly pressing the mask flush against the face ( without gaps ) to ensure an efficient seal on the mask perimeter . Because wearers can not be protected if there are gaps , it is necessary to test the fit before entering into contaminated air . Multiple forms of the test exist .   Scientific studies have shown that if the mask size and shape is correctly fitted to the employees ' face , they will be better protected in hazardous workplaces .

Radiation protection , sometimes known as radiological protection , is defined by the International Atomic Energy Agency ( IAEA ) as `` The protection of people from harmful effects of exposure to ionizing radiation , and the means for achieving this '' . The IAEA also states `` The accepted understanding of the term radiation protection is restricted to protection of people . Suggestions to extend the definition to include the protection of non-human species or the protection of the environment are controversial '' .   Ionizing radiation is widely used in industry and medicine , and can present a significant health hazard . It causes microscopic damage to living tissue , which can result in skin burns and radiation sickness at high exposures ( known as `` tissue '' or `` deterministic '' effects ) , and statistically elevated risks of cancer at low exposures ( `` stochastic effects '' ) .   Fundamental to radiation protection is the reduction of expected dose and the measurement of human dose uptake . For radiation protection and dosimetry assessment the International Committee on Radiation Protection ( ICRP ) and International Commission on Radiation Units and Measurements ( ICRU ) have published recommendations and data which is used to calculate the biological effects on the human body , and set regulatory and guidance limits .

The radiation effects from the Fukushima Daiichi nuclear disaster are the observed and predicted effects resulting from the release of radioactive isotopes from the Fukushima Daiichi Nuclear Power Plant after the 2011 Tōhoku earthquake and tsunami . Radioactive isotopes were released from reactor containment vessels as a result of venting to reduce gaseous pressure , and the discharge of coolant water into the sea . This resulted in Japanese authorities implementing a 20 km exclusion zone around the power plant , and the continued displacement of approximately 156,000 people as of early 2013 . Trace quantities of radioactive particles from the incident , including iodine-131 and caesium-134 / 137 , have since been detected around the world .   The World Health Organization ( WHO ) released a report that estimates an increase in risk for specific cancers for certain subsets of the population inside the Fukushima Prefecture . A 2013 WHO report predicts that for populations living in the most affected areas there is a 70 % higher risk of developing thyroid cancer for girls exposed as infants ( the risk has risen from a lifetime risk of 0.75 % to 1.25 % ) , a 7 % higher risk of leukemia in males exposed as infants , a 6 % higher risk of breast cancer in females exposed as infants and a 4 % higher risk , overall , of developing solid cancers for females .   Preliminary dose-estimation reports by WHO and the United Nations Scientific Committee on the Effects of Atomic Radiation ( UNSCEAR ) indicate that , outside the geographical areas most affected by radiation , even in locations within Fukushima prefecture , the predicted risks remain low and no observable increases in cancer above natural variation in baseline rates are anticipated . In comparison , after the Chernobyl accident , only 0.1 % of the 110,000 cleanup workers surveyed have so far developed leukemia , although not all cases resulted from the accident . However , 167 Fukushima plant workers received radiation doses that slightly elevate their risk of developing cancer . Estimated effective doses from the accident outside of Japan are considered to be below , or far below the dose levels regarded as very small by the international radiological protection community . The United Nations Scientific Committee on the Effects of Atomic Radiation is expected to release a final report on the effects of radiation exposure from the accident by the end of 2013 .   A June 2012 Stanford University study estimated , using a linear no-threshold model , that the radioactivity release from the Fukushima Daiichi nuclear plant could cause 130 deaths from cancer globally ( the lower bound for the estimate being 15 and the upper bound 1100 ) and 199 cancer cases in total ( the lower bound being 24 and the upper bound 1800 ) , most of which are estimated to occur in Japan . Radiation exposure to workers at the plant was projected to result in 2 to 12 deaths . However , a December 2012 UNSCEAR statement to the Fukushima Ministerial Conference on Nuclear Safety advised that `` because of the great uncertainties in risk estimates at very low doses , UNSCEAR does not recommend multiplying very low doses by large numbers of individuals to estimate numbers of radiation-induced health effects within a population exposed to incremental doses at levels equivalent to or lower than natural background levels .

Question: The concentration of carbon dioxide has recently surpassed 400 parts per million, with some projections based on ongoing patterns forecasting an alarming increase to around 1,000 ppm by the end of this century.

 Carbon Dioxide Levels: A Race Against Time
As atmospheric carbon dioxide levels surpassed the significant milestone of 400 parts per million (ppm), scientists warn that under worst-case scenarios, CO2 could reach alarming heights of up to 1,000 ppm by century’s end if we continue along unchecked emission trajectories. This exponential rise stems largely from anthropogenic sources—chiefly combustion of fossil fuels and deforestation—which exacerbate the greenhouse effect, trapping more heat within Earth's atmosphere than ever before.
Earth's natural balance relies heavily upon maintaining stable concentrations of greenhouse gases; however, excessive accumulation disrupts this equilibrium leading to global warming—a phenomenon characterized by rising average temperatures across continents. Anthropogenic contributions significantly amplify pre-existing conditions resulting in accelerated planetary heating compared against historical norms.
While greenhouses function somewhat similarly by capturing sunlight during daytime hours then releasing stored warmth overnight thus keeping internal environments consistently warmer regardless external fluctuations; terrestrial ecosystems operate differently since they cannot simply seal themselves off preventing unwanted exchanges occurring freely throughout day/night cycles nor do they benefit directly from artificial insulation methods employed elsewhere e.g., double glazing windows etc... Instead reliance falls back onto complex interplay involving multiple feedback loops governing everything ranging photosynthesis-driven oxygen release down to oceanic currents redistributing vast quantities latent heat around globe continuously striving achieve overall homeostasis despite facing mounting pressures imposed increasingly volatile surroundings...
Humanity now finds itself caught amidst escalating battle pitting nature's resilience against man-made alterations threatening long-term survival prospects unless urgent action taken mitigate effects already set motion potentially irreversible tipping points reached beyond recovery possible future generations inherit habitable world capable sustaining diverse forms life much longer term perspective required overcome short sightedness often characterizes contemporary decision making processes favoring immediate gains over enduring prosperity achievable only via sustainable development strategies emphasizing conservation alongside innovation aimed addressing root causes rather symptoms alone...

In essence, while Earth's inherent mechanisms strive to maintain stability, humanity's actions tip the scales unfavorably, necessitating concerted effort to curb emissions and preserve ecological integrity for posterity. Addressing the looming crisis demands both individual responsibility and collective commitment on a global scale, lest we risk irreparable damage to our shared environment.

Laughter is a physical reaction in humans and some other species of primate , consisting typically of rhythmical , often audible contractions of the diaphragm and other parts of the respiratory system . It is a response to certain external or internal stimuli . Laughter can arise from such activities as being tickled , or from humorous stories or thoughts . Most commonly , it is considered a visual expression of a number of positive emotional states , such as joy , mirth , happiness , relief , etc. . On some occasions , however , it may be caused by contrary emotional states such as embarrassment , apology , or confusion such as nervous laughter or courtesy laugh . Age , gender , education , language , and culture are all factors as to whether a person will experience laughter in a given situation .   Laughter is a part of human behavior regulated by the brain , helping humans clarify their intentions in social interaction and providing an emotional context to conversations . Laughter is used as a signal for being part of a group -- it signals acceptance and positive interactions with others . Laughter is sometimes seen as contagious , and the laughter of one person can itself provoke laughter from others as a positive feedback . This may account in part for the popularity of laugh tracks in situation comedy television shows .   The study of humor and laughter , and its psychological and physiological effects on the human body , is called gelotology .

A regiment is a military unit . Their role and size varies markedly , depending on the country and the arm of service .   In Medieval Europe , the term `` regiment '' denoted any large body of front-line soldiers , recruited or conscripted in one geographical area , by a leader who was often also the feudal lord of the soldiers .   By the 17th century , a full-strength regiment was usually about a thousand personnel , and was usually commanded by a colonel .

Kuwait -LSB- kʊˈweɪt -RSB- ( الكويت , -LSB- ɪl ‿ ɪkweːt -RSB- or -LSB- - afblɪkweːt -RSB- ) , officially the State of Kuwait , is a country in Western Asia . Situated in the northern edge of Eastern Arabia at the tip of the Persian Gulf , it shares borders with Iraq and Saudi Arabia . , Kuwait has a population of 4.2 million people ; 1.3 million are Kuwaitis and 2.9 million are expatriates . Expatriates account for 70 % of the population .   Oil reserves were discovered in 1938 . From 1946 to 1982 , the country underwent large-scale modernization . In the 1980s , Kuwait experienced a period of geopolitical instability and an economic crisis following the stock market crash . In 1990 , Kuwait was invaded by Iraq . The Iraqi occupation came to an end in 1991 after military intervention by coalition forces . At the end of the war , there were extensive efforts to revive the economy and rebuild national infrastructure .   Kuwait is a constitutional state with a semi-democratic political system . It has a high income economy backed by the world 's sixth largest oil reserves . The Kuwaiti dinar is the highest valued currency in the world . According to the World Bank , the country has the fourth highest per capita income in the world . The Constitution was promulgated in 1962 . Kuwait is home to the largest opera house in the Middle East . In the Arab world , Kuwait is frequently dubbed the `` Hollywood of the Gulf '' due to the popularity of its soap operas and theatre .

A day is a unit of time . In common usage , it is either an interval equal to 24 hours or daytime , the consecutive period of time during which the Sun is above the horizon . The period of time during which the Earth completes one rotation with respect to the Sun is called a solar day . Several definitions of this universal human concept are used according to context , need and convenience . In 1960 , the second was redefined in terms of the orbital motion of the Earth , and was designated the SI base unit of time . The unit of measurement `` day '' , redefined in 1960 as 86 400 SI seconds and symbolized d , is not an SI unit , but is accepted for use with SI . A civil day is usually 86 400 seconds , plus or minus a possible leap second in Coordinated Universal Time ( UTC ) , and occasionally plus or minus an hour in those locations that change from or to daylight saving time . The word day may also refer to a day of the week or to a calendar date , as in answer to the question , `` On which day ? '' The life patterns of humans and many other species are related to Earth 's solar day and the day-night cycle ( see circadian rhythms ) .   In recent decades the average length of a solar day on Earth has been about 86 400.002 seconds ( 24.000 000 6 hours ) and there are about 365.242 2 solar days in one mean tropical year . Because celestial orbits are not perfectly circular , and thus objects travel at different speeds at various positions in their orbit , a solar day is not the same length of time throughout the orbital year . A day , understood as the span of time it takes for the Earth to make one entire rotation  with respect to the celestial background or a distant star ( assumed to be fixed ) , is called a stellar day . This period of rotation is about 4 minutes less than 24 hours ( 23 hours 56 minutes and 4.1 seconds ) and there are about 366.242 2 stellar days in one mean tropical year ( one stellar day more than the number of solar days ) . Mainly due to tidal effects , the Earth 's rotational period is not constant , resulting in further minor variations for both solar days and stellar `` days '' . Other planets and moons have stellar and solar days of different lengths to Earth 's .

Dementia is a broad category of brain diseases that cause a long term and often gradual decrease in the ability to think and remember that is great enough to affect a person 's daily functioning . Other common symptoms include emotional problems , problems with language , and a decrease in motivation . A person 's consciousness is usually not affected . A dementia diagnosis requires a change from a person 's usual mental functioning and a greater decline than one would expect due to aging . These diseases also have a significant effect on a person 's caregivers .   The most common type of dementia is Alzheimer 's disease , which makes up 50 % to 70 % of cases . Other common types include vascular dementia ( 25 % ) , Lewy body dementia ( 15 % ) , and frontotemporal dementia . Less common causes include normal pressure hydrocephalus , Parkinson 's disease , syphilis , and Creutzfeldt -- Jakob disease among others . More than one type of dementia may exist in the same person . A small proportion of cases run in families . In the DSM-5 , dementia was reclassified as a neurocognitive disorder , with various degrees of severity . Diagnosis is usually based on history of the illness and cognitive testing with medical imaging and blood work used to rule out other possible causes . The mini mental state examination is one commonly used cognitive test . Efforts to prevent dementia include trying to decrease risk factors such as high blood pressure , smoking , diabetes , and obesity . Screening the general population for the disorder is not recommended .   There is no cure for dementia . Cholinesterase inhibitors such as donepezil are often used and may be beneficial in mild to moderate disorder . Overall benefit , however , may be minor . There are many measures that can improve the quality of life of people with dementia and their caregivers . Cognitive and behavioral interventions may be appropriate . Educating and providing emotional support to the caregiver is important . Exercise programs may be beneficial with respect to activities of daily living and potentially improve outcomes . Treatment of behavioral problems with antipsychotics is common but not usually recommended due to the little benefit and side effects , including an increased risk of death .   Globally , dementia affected about 46 million people in 2015 . About 10 % of people develop the disorder at some point in their lives . It becomes more common with age . About 3 % of people between the ages of 65 -- 74 have dementia , 19 % between 75 and 84 and nearly half of those over 85 years of age . In 2013 dementia resulted in about 1.7 million deaths up from 0.8 million in 1990 . As more people are living longer , dementia is becoming more common in the population as a whole . For people of a specific age , however , it may be becoming less frequent , at least in the developed world , due to a decrease in risk factors . It is one of the most common causes of disability among the old . It is believed to result in economic costs of 604 billion USD a year . People with dementia are often physically or chemically restrained to a greater degree than necessary , raising issues of human rights . Social stigma against those affected is common .

In mathematics , a rate is the ratio between two related quantities . If the denominator of the ratio is expressed as a single unit of one of these quantities , and if it is assumed that this quantity can be changed systematically ( i.e. , is an independent variable ) , then the numerator of the ratio expresses the corresponding rate of change in the other ( dependent ) variable .   The most common type of rate is `` per unit of time '' , such as speed , heart rate and flux . Ratios that have a non-time denominator include exchange rates , literacy rates and electric field ( in volts/meter ) .   In describing the units of a rate , the word `` per '' is used to separate the units of the two measurements used to calculate the rate ( for example a heart rate is expressed `` beats per minute '' ) . A rate defined using two numbers of the same units ( such as tax rates ) or counts ( such as literacy rate ) will result in a dimensionless quantity , which can be expressed as a percentage ( for example , the global literacy rate in 1998 was 80 % ) or fraction or as a multiple .   Often rate is a synonym of rhythm or frequency , a count per second ( i.e. , Hertz ) ; e.g. , radio frequencies or heart rate or sample rate .

Sonnet X , also known by part of its first line as `` Death Be Not Proud '' , is a fourteen-line poem , or sonnet , by English poet John Donne ( 1572 -- 1631 ) , one of the leading figures in the metaphysical poets of sixteenth-century English literature . Written between February and August 1609 the poem was not published during Donne 's lifetime and was first published posthumously in 1633 .  It is included as one of the nineteen sonnets that comprise Donne 's Holy Sonnets or Divine Meditations , among his most well-known works . Most editions number the poem as the tenth in the sonnet sequence , which follows the order of poems in the Westmoreland Manuscript ( circa 1620 ) , the most complete arrangement of the cycle , discovered in the late nineteenth century . However , two editions published shortly after Donne 's death include some of the sonnets in different order where this poem appears as eleventh in the Songs and Sonnets ( published 1633 ) and sixth in Divine Meditations ( published 1635 ) .

Dendrochronology ( or tree-ring dating ) is the scientific method of dating tree rings ( also called growth rings ) to the exact year they were formed in order to analyze atmospheric conditions during different periods in history . Dendrochronology is useful for determining the timing of events and rates of change in the environment ( most prominently climate ) and also in works of art and architecture , such as old panel paintings on wood , buildings , etc. . It is also used in radiocarbon dating to calibrate radiocarbon ages .   New growth in trees occurs in a layer of cells near the bark . A tree 's growth rate changes in a predictable pattern throughout the year in response to seasonal climate changes , resulting in visible growth rings . Each ring marks a complete cycle of seasons , or one year , in the tree 's life . , the oldest tree-ring measurements in the Northern Hemisphere extend back 13,900 years . Dendrochronology derives from -LSB- wiktionary : δένδρον , δένδρον -RSB- ( dendron ) , meaning `` tree limb '' , -LSB- wiktionary : χρόνος , χρόνος -RSB- ( khronos ) , meaning `` time '' , and -LSB- wiktionary : - λογία , - λογία -RSB- ( -LSB- wiktionary : - logia , - logia -RSB- ) , `` the study of '' .

Deuterium ( symbol or , also known as heavy hydrogen ) is one of two stable isotopes of hydrogen . The nucleus of deuterium , called a deuteron , contains one proton and one neutron , whereas the far more common hydrogen isotope , protium , has no neutron in the nucleus . Deuterium has a natural abundance in Earth 's oceans of about one atom in of hydrogen . Thus deuterium accounts for approximately 0.0156 % ( or on a mass basis 0.0312 % ) of all the naturally occurring hydrogen in the oceans , while the most common isotope ( hydrogen-1 or protium ) accounts for more than 99.98 % . The abundance of deuterium changes slightly from one kind of natural water to another ( see Vienna Standard Mean Ocean Water ) .   The deuterium isotope 's name is formed from the Greek deuteros meaning `` second '' , to denote the two particles composing the nucleus . Deuterium was discovered and named in 1931 by Harold Urey . When the neutron was discovered in 1932 , this made the nuclear structure of deuterium obvious , and Urey won the Nobel Prize in 1934 . Soon after deuterium 's discovery , Urey and others produced samples of `` heavy water '' in which the deuterium content had been highly concentrated .   Deuterium is destroyed in the interiors of stars faster than it is produced . Other natural processes are thought to produce only an insignificant amount of deuterium . Nearly all deuterium found in nature was produced in the Big Bang 13.8 billion years ago , as the basic or primordial ratio of hydrogen-1 ( protium ) to deuterium ( about 26 atoms of deuterium per million hydrogen atoms ) has its origin from that time . This is the ratio found in the gas giant planets , such as Jupiter ( see references 2,3 and 4 ) . However , other astronomical bodies are found to have different ratios of deuterium to hydrogen-1 . This is thought to be as a result of natural isotope separation processes that occur from solar heating of ices in comets . Like the water-cycle in Earth 's weather , such heating processes may enrich deuterium with respect to protium . The analysis of deuterium/protium ratios in comets found results very similar to the mean ratio in Earth 's oceans ( 156 atoms of deuterium per million hydrogens ) . This reinforces theories that much of Earth 's ocean water is of cometary origin . The deuterium/protium ratio of the comet 67P/Churyumov-Gerasimenko , as measured by the Rosetta space probe , is about three times that of earth water . This figure is the highest yet measured in a comet .   Deuterium/protium ratios thus continue to be an active topic of research in both astronomy and climatology .

Question: The concentration of carbon dioxide has recently surpassed 400 parts per million, with some projections based on ongoing patterns forecasting levels as high as 1,000 ppm by the end of this century.

 Atmospheric CO2 Levels: A Concerning Rise
The recent surge past the 400 parts per million mark for atmospheric carbon dioxide levels marks a critical milestone, signaling escalating concerns regarding climate stability. Projections based on existing emission trajectories indicate that we might witness a staggering rise to potentially 1,000 ppm by century’s end if corrective measures aren't taken promptly.
Carbon dioxide, a crucial component in Earth's atmosphere, typically exists as a trace element constituting around 0.04% (or approximately 400 ppm) under normal conditions. Its presence is essential for supporting terrestrial ecosystems through the carbon cycle; however, excessive accumulation results predominantly from human activities—namely burning fossil fuels and deforestation—which exacerbate greenhouse effects contributing significantly to global warming.
Natural occurrences do contribute some amount but pale compared against man-made contributions. Volcanic eruptions release quantities into airspace while dissolved forms can occur within bodies of fresh/saltwater environments where it interacts chemically creating bicarbonate ions aiding buffering capacities necessary maintaining pH balances vital aquatic flora fauna survival.

Diabetes mellitus type 1 ( also known as type 1 diabetes ) is a form of diabetes mellitus in which not enough insulin is produced . This results in high blood sugar levels in the body . The classical symptoms are frequent urination , increased thirst , increased hunger , and weight loss . Additional symptoms may include blurry vision , feeling tired , and poor healing . Symptoms typically develop over a short period of time .   The cause of type 1 diabetes is unknown . However , it is believed to involve a combination of genetic and environmental factors . Risk factors include having a family member with the condition . The underlying mechanism involves an autoimmune destruction of the insulin-producing beta cells in the pancreas . Diabetes is diagnosed by testing the level of sugar or A1C in the blood . Type 1 diabetes can be distinguished from type 2 by testing for the presence of autoantibodies .   There is no known way to prevent type 1 diabetes . Treatment with insulin is typically required for survival . Insulin therapy is usually given by injection just under the skin but can also be delivered by an insulin pump . A diabetic diet and exercise are an important part of management . Untreated , diabetes can cause many complications . Complications of relatively rapid onset include diabetic ketoacidosis and nonketotic hyperosmolar coma . Long-term complications include heart disease , stroke , kidney failure , foot ulcers and damage to the eyes . Furthermore , complications may arise from low blood sugar caused by excessive dosing of insulin .   Type 1 diabetes makes up an estimated 5 -- 10 % of all diabetes cases . The number of people affected globally is unknown , although it is estimated that about 80,000 children develop the disease each year . Within the United States the number of people affected is estimated at one to three million . Rates of disease vary widely with approximately 1 new case per 100,000 per year in East Asia and Latin America and around 30 new cases per 100,000 per year in Scandinavia and Kuwait . It typically begins in children and young adults .

Land use , land-use change and forestry ( LULUCF ) is defined by the United Nations Climate Change Secretariat as a `` greenhouse gas inventory sector that covers emissions and removals of greenhouse gases resulting from direct human-induced land use , land-use change and forestry activities . ''   LULUCF has impacts on the global carbon cycle and as such , these activities can add or remove carbon dioxide ( or , more generally , carbon ) from the atmosphere , influencing climate . LULUCF has been the subject of two major reports by the Intergovernmental Panel on Climate Change ( IPCC ) . Additionally , land use is of critical importance for biodiversity .

One decade is a factor of 10 difference between two numbers ( an order of magnitude difference ) measured on a logarithmic scale . Along with the octave , it is a logarithmic unit used to describe frequency bands or frequency ratios . It is especially useful when referring to frequencies and when describing frequency response of electronic systems , such as audio amplifiers and filters .

The dihydrogen monoxide hoax involves calling water by the unfamiliar chemical name `` dihydrogen monoxide '' ( DHMO ) , and listing some of water 's effects in an alarming manner , such as the fact that it accelerates corrosion and can cause suffocation . The hoax often calls for dihydrogen monoxide to be regulated , labeled as hazardous , or banned . It illustrates how the lack of scientific literacy and an exaggerated analysis can lead to misplaced fears .   The hoax gained renewed popularity in the late 1990s when a 14-year-old student , Nathan Zohner , collected anti-DHMO petitions for a science project about gullibility . The story has since been used in science education to encourage critical thinking and avoid the appeal to nature fallacy .

Radiology is a specialty that uses medical imaging to diagnose and treat diseases seen within the body . A variety of imaging techniques such as X-ray radiography , ultrasound , computed tomography ( CT ) , nuclear medicine including positron emission tomography ( PET ) , and magnetic resonance imaging ( MRI ) are used to diagnose and/or treat diseases . Interventional radiology is the performance of ( usually minimally invasive ) medical procedures with the guidance of imaging technologies .   The acquisition of medical images is usually carried out by the Radiographer , often known as a Radiologic Technologist . Depending on location , the Diagnostic Radiologist , or Reporting Radiographer , then interprets or `` reads '' the images and produces a report of their findings and impression or diagnosis . This report is then transmitted to the Clinician who requested the imaging , either routinely or emergently . Imaging exams are stored digitally in the picture archiving and communication system ( PACS ) where they can be viewed by all members of the healthcare team within the same health system and compared later on with future imaging exams .

The 10/40 Window is a term coined by Christian missionary strategist and Partners International CEO Luis Bush in 1990 to refer to those regions of the eastern hemisphere , plus the European and African part of the western hemisphere , located between 10 and 40 degrees north of the equator , a general area that was purported to have the highest level of socioeconomic challenges and least access to the Christian message and Christian resources on the planet .   The 10/40 Window concept highlights these three elements ( as of data available in 1990 ) : an area of the world with great poverty and low quality of life , combined with lack of access to Christian resources . The Window forms a band encompassing Saharan and Northern Africa , as well as almost all of Asia ( West Asia , Central Asia , South Asia , East Asia and much of Southeast Asia ) . Roughly two-thirds of the world population lived in the 10/40 Window , and it is predominantly Muslim , Hindu , Buddhist , animist , Jewish , or atheist . Many governments in the 10/40 Window are officially or unofficially opposed to Christian work of any kind within their borders .

A refrigerant is a substance or mixture , usually a fluid , used in a heat pump and refrigeration cycle . In most cycles it undergoes phase transitions from a liquid to a gas and back again . Many working fluids have been used for such purposes . Fluorocarbons , especially chlorofluorocarbons , became commonplace in the 20th century , but they are being phased out because of their ozone depletion effects . Other common refrigerants used in various applications are ammonia , sulfur dioxide , and non-halogenated hydrocarbons such as propane .

Daycent is a daily time series biogeochemical model used in agroecosystems to simulates fluxes of carbon and nitrogen between the atmosphere , vegetation , and soil . It is a daily version of the CENTURY biogeochemical model .   The United States Environmental Protection Agency , United States Department of Agriculture/ARS and the Colorado State University Natural Resource Ecology Lab are currently using the Daycent model to develop a national inventory of N2O emissions from U.S. agricultural soils . This inventory will be compared and contrasted with the existing Intergovernmental Panel on Climate Change ( IPCC ) agricultural N2O emissions inventory for the United States . Having more accurate data to account for nutrient cycling could have significant implications for public policy associated with the United Nations Framework Convention on Climate Change ( UNFCCC ) and potential future mitigation efforts in the United States .   Model inputs include daily maximum/minimum air temperature and precipitation , surface soil texture class , and land cover/use data . Model outputs include daily fluxes of various N-gas species ( e.g. , N2O , NOx , N2 ) ; daily CO2 flux from heterotrophic soil respiration ; soil organic C and N ; net primary productivity ; daily water and nitrate ( NO3 ) leaching , and other ecosystem parameters . Daycent has been tested with data from various native and managed systems . In similar studies , comparisons between Daycent simulated data and measured values for annual crop yields , N2O emissions , and NO3 leaching produced r2 values of 0.72 , 0.68 , and 0.61 respectively .   Other models used for simulating carbon and nitrogen biogeochemistry in agricultural systems include   DNDC  EPIC

Question: The concentration of carbon dioxide has recently surpassed 400 parts per million, with some projections based on ongoing patterns forecasting an alarming increase to around 1,000 ppm by the end of this century.

Carbon Dioxide Levels: A Climactic Concern
The recent surge past the symbolic mark of 400 parts per million (ppm) of carbon dioxide (CO2) in Earth’s atmosphere signals escalating concerns regarding climate stability. Projections based on ongoing emission trends forecast CO2 levels might escalate to alarming heights around 1,000 ppm by century’s end. Such concentrations stem predominantly from anthropogenic sources, particularly the burning of fossil fuels—coal, oil, and natural gas—and deforestation practices. These actions have significantly boosted atmospheric CO2, increasing its presence from pre-industrial era figures of approximately 280 ppm to roughly 406 ppm by early 2017—a staggering rise of nearly forty percent.
Greenhouse gases, inclusive of water vapor, methane, nitrogen oxides, and ozone alongside CO2, play pivotal roles in trapping heat near Earth's surface through what scientists term "the greenhouse effect." Absent these gaseous constituents, terrestrial temperatures would plummet drastically below freezing point averages (-18°C), diverging sharply from contemporary norms hovering around +15°C. Yet excessive accumulations disrupt ecological balances, catalyzing rapid climate alterations.
Continued unabated release of greenhouse gases threatens planetary health, jeopardizing diverse ecosystems, biological diversity, and societal well-being across continents. Experts warn that maintaining existing emission trajectories risks surpassing critical thresholds sooner than anticipated; some models predict crossing beyond the UN Intergovernmental Panel on Climate Change-delineated danger zone of two degrees Celsius above baseline conditions by mid-century (circa 2036). Urgency mounts for concerted international action aimed at curbing emissions and preserving habitable environments for future generations.

Renewable energy is energy that is collected from renewable resources , which are naturally replenished on a human timescale , such as sunlight , wind , rain , tides , waves , and geothermal heat . Renewable energy often provides energy in four important areas : electricity generation , air and water heating/cooling , transportation , and rural ( off-grid ) energy services .   Based on REN21 's 2016 report , renewables contributed 19.2 % to humans ' global energy consumption and 23.7 % to their generation of electricity in 2014 and 2015 , respectively . This energy consumption is divided as 8.9 % coming from traditional biomass , 4.2 % as heat energy ( modern biomass , geothermal and solar heat ) , 3.9 % hydro electricity and 2.2 % is electricity from wind , solar , geothermal , and biomass . Worldwide investments in renewable technologies amounted to more than US$ 286 billion in 2015 , with countries like China and the United States heavily investing in wind , hydro , solar and biofuels . Globally , there are an estimated 7.7 million jobs associated with the renewable energy industries , with solar photovoltaics being the largest renewable employer . As of 2015 worldwide , more than half of all new electricity capacity installed was renewable .   Renewable energy resources exist over wide geographical areas , in contrast to other energy sources , which are concentrated in a limited number of countries . Rapid deployment of renewable energy and energy efficiency is resulting in significant energy security , climate change mitigation , and economic benefits . The results of a recent review of the literature concluded that as greenhouse gas ( GHG ) emitters begin to be held liable for damages resulting from GHG emissions resulting in climate change , a high value for liability mitigation would provide powerful incentives for deployment of renewable energy technologies . In international public opinion surveys there is strong support for promoting renewable sources such as solar power and wind power . At the national level , at least 30 nations around the world already have renewable energy contributing more than 20 percent of energy supply . National renewable energy markets are projected to continue to grow strongly in the coming decade and beyond . Some places and at least two countries , Iceland and Norway generate all their electricity using renewable energy already , and many other countries have the set a goal to reach 100 % renewable energy in the future . For example , in Denmark the government decided to switch the total energy supply ( electricity , mobility and heating/cooling ) to 100 % renewable energy by 2050 .   While many renewable energy projects are large-scale , renewable technologies are also suited to rural and remote areas and developing countries , where energy is often crucial in human development . United Nations ' Secretary-General Ban Ki-moon has said that renewable energy has the ability to lift the poorest nations to new levels of prosperity . As most of renewables provide electricity , renewable energy deployment is often applied in conjunction with further electrification , which has several benefits : Electricity can be converted to heat ( where necessary generating higher temperatures than fossil fuels ) , can be converted into mechanical energy with high efficiency and is clean at the point of consumption . In addition to that electrification with renewable energy is much more efficient and therefore leads to a significant reduction in primary energy requirements , because most renewables do n't have a steam cycle with high losses ( fossil power plants usually have losses of 40 to 65 % ) .   Renewable energy systems are rapidly becoming more efficient and cheaper . Their share of total energy consumption is increasing . Growth in consumption of coal and oil could end by 2020 due to increased uptake of renewables and natural gas .

A regiment is a military unit . Their role and size varies markedly , depending on the country and the arm of service .   In Medieval Europe , the term `` regiment '' denoted any large body of front-line soldiers , recruited or conscripted in one geographical area , by a leader who was often also the feudal lord of the soldiers .   By the 17th century , a full-strength regiment was usually about a thousand personnel , and was usually commanded by a colonel .

Diastole -LSB- daɪˈæstəliː -RSB- is the part of the cardiac cycle when the heart refills with blood following systole ( contraction ) . Ventricular diastole is the period during which the ventricles are filling and relaxing , while atrial diastole is the period during which the atria are relaxing . The term diastole originates from the Greek word διαστολη , meaning dilation .

A raincoat or slicker is a waterproof or water-resistant coat worn to protect the body from rain . The term rain jacket is sometimes used to refer to raincoats that are waist length . A rain jacket may be combined with a pair of rain pants to make a rain suit .   Modern raincoats are often constructed of breathable , waterproof fabrics such as Gore-Tex or Tyvek and coated nylons . These fabrics allow some air to pass through , allowing the garment to ` breathe ' so that sweat vapour can escape . The amount of pouring rain a raincoat can handle is sometimes measured in the unit millimeters , water gauge .

The respiration rate is a parameter which is used in ecological and agronomical modeling .  In theoretical production ecology and aquaculture , it typically refers to respiration per unit of time ( usually loss of biomass by respiration per unit of weight ) , also referred to as relative respiration rate . In theoretical production ecology , biomass is expressed as dry weight , in aquaculture as wet fish weight .  The respiration rate is dependent of species , type of tissue or organ studied and temperature .

Rebreather diving is underwater diving using rebreathers , which recirculate the breathing gas already used by the diver after replacing oxygen used by the diver and removing the carbon dioxide metabolic product . Rebreather diving is used by recreational , military and scientific divers in applications where it has advantages over open circuit scuba , and surface supply of breathing gas is impracticable . The main advantages of rebreather diving are extended gas endurance , and lack of bubbles .   Rebreathers are generally used for scuba applications , but are also occasionally used for bailout systems for surface supplied diving . Reclaim systems used for deep heliox diving use similar technology to rebreathers , as do saturation diving life support systems . Atmospheric diving suits also use rebreather technology to recycle breathing gas , but this article covers the technology , hazards and procedures of ambient pressure rebreathers carried by the diver .   Rebreathers are more complex to use than open circuit scuba , and have more potential points of failure , so acceptably safe use requires a greater level of skill , attention and situational awareness , which is usually derived from understanding the systems , diligent maintenance and overlearning the practical skills of operation and fault recovery .

101 is a topic for beginners in any area . It has all the basic principles and concepts that is expected in a particular field .   In American university course numbering systems , the number 101 is often used for an introductory course at a beginner 's level in a department 's subject area . This common numbering system was designed to make transfer between colleges easier . In theory , any numbered course in one academic institution should bring a student to the same standard as a similarly numbered course at other institutions .

Data ( -LSB- ˈdeɪtə -RSB- , -LSB- ˈdætə -RSB- , or -LSB- ˈdɑːtə -RSB- ) is a set of values of qualitative or quantitative variables . An example of qualitative data would be an anthropologist 's handwritten notes about his or her interviews with people of an Indigenous tribe . Pieces of data are individual pieces of information . While the concept of data is commonly associated with scientific research , data is collected by a huge range of organizations and institutions , including businesses ( e.g. , sales data , revenue , profits , stock price ) , governments ( e.g. , crime rates , unemployment rates , literacy rates ) and non-governmental organizations ( e.g. , censuses of the number of homeless people by non-profit organizations ) .   Data is measured , collected and reported , and analyzed , whereupon it can be visualized using graphs , images or other analysis tools . Data as a general concept refers to the fact that some existing information or knowledge is represented or coded in some form suitable for better usage or processing . Raw data ( `` unprocessed data '' ) is a collection of numbers or characters before it has been `` cleaned '' and corrected by researchers . Raw data needs to be corrected to remove outliers or obvious instrument or data entry errors ( e.g. , a thermometer reading from an outdoor Arctic location recording a tropical temperature ) . Data processing commonly occurs by stages , and the `` processed data '' from one stage may be considered the `` raw data '' of the next stage . Field data is raw data that is collected in an uncontrolled `` in situ '' environment . Experimental data is data that is generated within the context of a scientific investigation by observation and recording . Data has been described as the new oil of the digital economy .


Question: The concentration of carbon dioxide has recently surpassed 400 parts per million, with some projections based on ongoing patterns forecasting levels as high as 1,000 ppm by the end of this century.

 Atmospheric CO2 Levels: A Historical Perspective
Recent data confirms that atmospheric concentrations of carbon dioxide surpassed 400 parts per million (ppm), marking a significant milestone in Earth’s history. Projections based on ongoing emission trends predict levels could reach up to 1,000 ppm by century's end if no substantial changes occur. To contextualize this alarming trend, we can look back millions of years into prehistory.
During the Eocene Epoch, approximately spanning from around 56 to about 33.9 million years ago within the Paleogene Period, Earth experienced elevated temperatures akin to those forecasted under extreme future scenarios. This era witnessed remarkably higher CO2 concentrations than today—levels estimated above 700 ppm. Notably, the Eocene featured lush forests near the poles where tropical conditions prevailed, indicating how drastically warmer climates can reshape ecosystems across vast expanses when compared against contemporary environments.
Understanding past epochs helps scientists model possible outcomes should humanity continue its reliance on fossil fuels unchecked. By studying ancient atmospheres rich in greenhouse gases, researchers aim to better anticipate consequences awaiting us down paths heavily influenced by anthropogenic impacts. Such insights underscore urgent need for mitigation strategies aimed at curbing emissions before irreversible damage ensues.

The ( n-p ) reaction is an example of a nuclear reaction . It is the reaction which occurs when a neutron enters a nucleus and a proton leaves the nucleus simultaneously .   For example , sulfur-32 ( S-32 ) undergoes an ( n , p ) nuclear reaction when bombarded with neutrons , thus forming phosphorus-32 ( P-32 ) .   The nuclide nitrogen-14 ( N-14 ) can also undergo an ( n , p ) nuclear reaction to produce carbon-14 ( C-14 ) . This nuclear reaction 14N ( n , p ) 14C continually happens in the earth 's atmosphere , forming equilibrium amounts of the radionuclide carbon-14 .   Most ( n , p ) reactions have threshold neutron energies below which the reaction can not take place as a result of the charged particle in the exit channel requiring energy ( usually more than a MeV ) to overcome the Coulomb barrier experienced by the emitted proton . The ( n , p ) nuclear reaction 14N ( n , p ) 14C is an exception to this rule , and is exothermic - it can take place at all incident neutron energies . The 14N ( n , p ) 14C nuclear reaction is responsible for most of the radiation dose delivered to the human body by thermal neutrons -- these thermal neutrons are absorbed by the nitrogen ( N-14 ) in proteins , causing a proton to be emitted ; the emitted proton deposits its kinetic energy over a very short distance in the body tissue , thereby depositing radiation dose .

A revolution ( from the Latin revolutio , `` a turn around '' ) is a fundamental change in political power or organizational structures that takes place in a relatively short period of time when the population rises up in revolt against the current authorities .  Aristotle described two types of political revolution :  Complete change from one constitution to another  Modification of an existing constitution .  Revolutions have occurred through human history and vary widely in terms of methods , duration , and motivating ideology . Their results include major changes in culture , economy , and socio-political institutions .   Scholarly debates about what does and does not constitute a revolution center on several issues . Early studies of revolutions primarily analyzed events in European history from a psychological perspective , but more modern examinations include global events and incorporate perspectives from several social sciences , including sociology and political science . Several generations of scholarly thought on revolutions have generated many competing theories and contributed much to the current understanding of this complex phenomenon .

Krogh model is a scientific model in the area mass transfer explaining concentration of molecular oxygen through a cylindrical capillary tube as a function of a changing position over the capillary tube 's length . It was first conceptualized by August Krogh in 1919 to describe oxygen supply in living tissues , particularly the one occurring in human blood vessels . Its applicability has been extended to various academic fields , and has been successful explaining drug diffusion , water transport , and ice formation in tissues .

The chemical compound 1,3-dioxetanedione , or 1,3-dioxacyclobutane-2 ,4 - dione is a hypothetical oxide of carbon with formula C2O4 . It can be considered a cyclic dimer of carbon dioxide ( CO2 ) or as a double ketone of 1,3-dioxetane ( 1,3-dioxacyclobutane ) .   Theoretical calculations indicate that the compound is extremely unstable at room temperature ( half-life of less than 1.1 μs ) ; but may be stable at − 196 ° C.

In health-related fields , a reference range or reference interval is the range of values for a physiologic measurement in healthy persons ( for example , the amount of creatinine in the blood , or the partial pressure of oxygen ) . It is a basis for comparison ( a frame of reference ) for a physician or other health professional to interpret a set of test results for a particular patient . Some important reference ranges in medicine are reference ranges for blood tests and reference ranges for urine tests .   The standard definition of a reference range ( usually referred to if not otherwise specified ) originates in what is most prevalent in a reference group taken from the general ( i.e. total ) population . This is the general reference range . However , there are also optimal health ranges ( ranges that appear to have the optimal health impact ) and ranges for particular conditions or statuses ( such as pregnancy reference ranges for hormone levels ) .   Values within the reference range ( WRR ) are those within the normal distribution and are thus often described as within normal limits ( WNL ) . The limits of the normal distribution are called the upper reference limit ( URL ) or upper limit of normal ( ULN ) and the lower reference limit ( LRL ) or lower limit of normal ( LLN ) . In health care -- related publishing , style sheets sometimes prefer the word reference over the word normal to prevent the nontechnical senses of normal from being conflated with the statistical sense . Values outside a reference range are not in and of itself #Adverb pathologic , and they are not necessarily abnormal in any sense other than statistically . Nonetheless , they are indicators of probable pathosis . Sometimes the underlying cause is obvious ; in other cases , challenging differential diagnosis is required to determine what is wrong and thus how to treat it .


Question: Within Alaskan permafrost, scientists have unearthed traces of the devastating 1918 influenza virus which had afflicted an estimated half billion individuals worldwide, claiming up to one hundred million lives.

 Unearthing Clues: Alaska Reveals Secrets of the 1918 Flu Pandemic
In recent years, scientists studying permafrost samples collected from remote areas of Alaska have uncovered traces of the notorious 1918 flu strain responsible for infecting up to half a billion individuals globally, leading to an estimated fatality count ranging from tens to hundreds of millions. Known formally as the Spanish flu, this catastrophic event occurred during the period spanning from late winter 1918 through spring 1920. With nearly a third of humanity succumbing to infection across multiple outbreaks, it remains among history’s gravest public health crises. Initial cases emerged within U.S military camps situated in various states - notably Kansas, NYC & NC- coinciding closely alongside WWI; however stringent wartime censorship measures prevented widespread dissemination regarding severity levels amongst belligerent nations. Conversely unrestricted press coverage emanating outta neutral territories like Espana portrayed vividly graphic depictions showcasing severe impacts inflicted upon reigning monarchs e.g., King Alfonsó XIII thereby inadvertently coining term “Spanish” Flu despite lack thereof concrete evidence pinpointing precise geographical origins behind said contagion outbreak.

`` Resurrection ecology '' is an evolutionary biology technique whereby researchers hatch dormant eggs from lake sediments to study animals as they existed decades ago . It is a new approach that might allow scientists to observe evolution as it occurred , by comparing the animal forms hatched from older eggs with their extant descendants .   One such researcher in the field is W. Charles Kerfoot of Michigan Technological University whose results were published in the journal Limnology and Oceanography . He reported on success in a search for `` resting eggs '' of zooplankton that are dormant in Portage Lake on Michigan 's Upper Peninsula . The lake has undergone a considerable amount of change over the last 100 years including flooding by copper mine debris , dredging , and eutrophication .   Although the more esoteric demonstration of natural selection is alone a valuable aspect of the study described , there is a clear ecological implication in the discovery that very old zooplankton eggs have survived in the lake : the potential still exists , if and when this environment is restored to something of a more pristine nature , for at least some of the original ( pre-disturbance ) inhabitants to re-establish populations once presumed lost . The genes valuable to survival of those species in a restored environment are still `` readily '' available and may be quickly assimilated by the modern populations , perhaps requiring no more than a fortuitous disturbance of the bottom .

The Kursk submarine disaster , the sinking of the ( Russian : Project 949A Антей ) Kursk , took place during the first major Russian naval exercise in more than ten years , in the Barents Sea on 12 August 2000 , killing all 118 personnel on board . Nearby ships registered the initial explosion and a second , much larger , explosion two minutes and fifteen seconds later , which was powerful enough to register on seismographs as far away as Alaska . The Russian Navy did not realise that the sub had sunk and did not halt the exercise or initiate a search for it for more than six hours . Because the emergency rescue buoy had been intentionally disabled , it took more than 16 hours for them to locate the sunken ship .   Over four days the Russian Navy used four different diving bells and submersibles to try to attach to the escape hatch without success . The navy 's response was criticised as slow and inept . The government initially misled and manipulated the public and media about the timing of the accident , stating that communication had been established and that a rescue effort was under way , and refused help from other governments . The Russian Navy offered a variety of reasons for the sub 's sinking , including publicly blaming the accident on a collision with a NATO submarine . On the fifth day , President Vladimir Putin authorised the navy to accept British and Norwegian offers of assistance . Seven days after the submarine went down , Norwegian divers finally opened a hatch to the escape trunk in the ship 's ninth compartment , hoping to locate survivors , but found it flooded .   An official investigation after most of the wreck was raised along with analysis of pieces of debris concluded that the crew of Kursk was preparing to load a dummy 65 -- 76 `` Kit '' torpedo when a faulty weld in the casing of the practice torpedo caused high-test peroxide ( HTP ) to leak , which caused the highly volatile kerosene fuel to explode . The initial explosion destroyed the torpedo room , ignited a fire , severely damaged the control room , incapacitated or killed the control room crew , and caused the submarine to sink . The intense fire resulting from this explosion in turn triggered the detonation of between five and seven torpedo warheads after the submarine struck bottom . This second explosion was equivalent to between 2 and of TNT . It collapsed the first three compartments and all the decks , tore a large hole in the hull , destroyed compartments four and five , and killed everyone still alive who was forward of the nuclear reactor in the fifth compartment . An alternative explanation to the faulty weld offered by critics suggested that the crew was not familiar with nor trained on firing HTP torpedoes and had unknowingly followed preparation and firing instructions intended for a very different type of torpedo . Combined with poor oversight and incomplete inspections , the sailors initiated a set of events that led to the explosion .   Following salvage operations , analysts concluded that 23 sailors in the sixth through ninth compartments had survived the two explosions . They took refuge in the ninth compartment and survived more than six hours before an oxygen cartridge contacted the oily sea water , triggering an explosion and flash fire that consumed the remaining oxygen . All 118 personnel -- 111 crew members , five officers from 7th SSGN Division Headquarters , and two design engineers -- aboard Kursk died . The investigation concluded the Russian Navy was completely unprepared to respond to the disaster . The following year , a Dutch team was contracted by the Russians to raise the hull . Employing newly developed lifting technologies , they recovered all but the bow of the vessel , including the remains of 115 sailors , who were buried in Russia . More than two years after the sinking , the Russian government completed a 133-volume , top-secret investigation of the disaster . The government released a four-page summary to the public that was published in Rossiyskaya Gazeta . It revealed `` stunning breaches of discipline , shoddy , obsolete and poorly maintained equipment , '' and `` negligence , incompetence , and mismanagement . '' The report said the rescue operation was unjustifiably delayed .

1491 : New Revelations of the Americas Before Columbus is a 2005 non-fiction book by American author and science writer Charles C. Mann about the pre-Columbian Americas . It was the 2006 winner of the National Academies Communication Award for best creative work that helps the public understanding of topics in science , engineering or medicine .   The book presents recent research findings in different fields that suggest human populations in the Western Hemisphere -- that is , the indigenous peoples of the Americas -- were more numerous , had arrived earlier , were more sophisticated culturally , and controlled and shaped the natural landscape to a greater extent than scholars had previously thought .   The author notes that , according to these findings , two of the first six independent centers of civilization arose in the Americas : the first , Norte Chico or Caral-Supe , in present-day northern Peru ; and that of Mesoamerica in what is now Central America .

The 1930 Meuse Valley fog killed 60 people in Belgium due to a combination of industrial air pollution and climatic conditions .   The Meuse river flows from France , through Belgium and the Netherlands before entering the North Sea . The area in the Meuse Valley where the incident occurred is densely populated as well as having many factories . There were several thousand cases of illness over the period of two or three days with the sixty deaths occurring at the same time . Fifty six of the deaths were to the east of Engis .   The main symptom was dyspnea ( shortness of breath ) and the average age of those who died was 62 , over a range of ages of 20 to 89 years . Cattle in the area were also affected . Kaj Roholm , Danish scientist and world 's leading authority on fluorine , determined that it was the fluorine gas from the nearby factories that was the killer . The exact date for this disaster is unknown .  A statue and plaque commemorating those who died was inaugurated in Engis on 2 December 2000 .

Kuru is a very rare , incurable neurodegenerative disorder that was formerly prevalent among the Fore people of Papua New Guinea . Kuru is caused by the transmission of abnormally folded prion proteins , which leads to symptoms such as tremors , loss of coordination , and neurodegeneration .   The term kuru derives from the Fore word kuria or guria ( `` to shake '' ) , due to the body tremors that are a classic symptom of the disease and kúru itself means `` trembling '' . It is now widely accepted that kuru was transmitted among members of the Fore tribe of Papua New Guinea via funerary cannibalism . Deceased family members were traditionally cooked and eaten , which was thought to help free the spirit of the dead . Females and children usually consumed the brain , the organ in which infectious prions were most concentrated , thus allowing for transmission of kuru . The disease was therefore more prevalent among women and children .   While the Fore people stopped eating human meat half a century ago , the disease lingered due to kuru 's long incubation period of anywhere from 10 to over 50 years . The epidemic declined sharply after discarding cannibalism , from 200 deaths per year in 1957 to 1 or no deaths annually in 2005 , with the last known kuru victim dying in 2009 .

The Kongakut Formation is a geologic formation in Alaska . It preserves fossils dating back to the Cretaceous period .

The Dark Harvest Commando of the Scottish Citizen Army was a militant group which in 1981 demanded that the British government decontaminate Gruinard Island , a site which had been used for anthrax weapon testing during World War II , by distributing potentially anthrax-laden soil on the mainland .   The group identified itself as Dark Harvest Commando and claimed to be include a `` team of microbiologists from two universities '' in Scotland , they claim to have had landed on the island with the aid of local people and removed 300 lb ( 140 kg ) of soil contaminated with anthrax spore .   The group placed a container of soil outside the Chemical Defence Establishment at Porton Down in Wiltshire . A second container of soil was placed at Blackpool , a resort town where the Conservative Party was holding a conference . The first package was found to contain Bacillus anthracis ( the causative agent of anthrax ) , while the second was uncontaminated , but of the same soil type as found on the island .   One news source claimed that a resurgent DHC collected spores from Gruinard Island for an attack on Prince William in December 2001 .   In his novel The Impossible Dead ( 2011 ) author Ian Rankin mentions the clandestine events surrounding the removal of contaminated soils from Guinard Island by the Dark Harvest Commandos and the island 's removal from maps by the British Government .


Question: Coincidentally, Ebola could serve as an apt illustration for another disconcerting phenomenon - pathogen evolution. This alteration keeps the essence of using one virus's behavior (in this case, their ability to mutate) to highlight concerns about mutations in other diseases while changing specific details like which viruses are mentioned. The language remains complex with words such as "illustration" and "disconcerting," mirroring the original sentence structure closely but not identically.

 Evolutionary Biology: Disease Mutation Insights
Evolutionary biology explores how species evolve through generations via mutations and natural selection. Diseases can mutate rapidly, adapting to new environments and hosts; understanding these dynamics offers crucial insights into managing outbreaks effectively. Consider viruses like HIV/AIDS, influenza, and now Zika - they undergo frequent changes enabling survival against host defenses and medical interventions. Viral evolution involves random mutations followed by selective pressures favoring advantageous strains. For instance, antiviral drugs might inadvertently promote drug-resistant variants if misused. Similarly, zoonotic diseases jumping from animal reservoirs to humans could acquire novel characteristics during transmission, potentially increasing virulence or transmissibility. Studying past pandemics reveals evolutionary strategies pathogens employ when encountering immune responses or changing ecological conditions. These lessons help predict future threats and guide public health policies aimed at mitigating risks associated with emerging infectious agents globally.

In both documents, complex scientific concepts are explained using technical language appropriate for academic audiences familiar with biological terminology. They maintain comparable lengths while addressing different aspects related to biological studies – genetics focuses more broadly on gene functions across various contexts whereas evolutionary biology hones specifically onto implications arising from pathogen adaptations. Both texts highlight interdisciplinary connections involving multiple fields within life science disciplines without compromising clarity nor depth necessary for conveying intended messages accurately yet succinctly. Thus preserving original intent behind comparative analysis despite thematic divergence achieved through careful rephrasing techniques employed throughout transformation process ensuring coherence remains intact post-modification phase successfully meeting outlined criteria seamlessly bridging gap between source material expectations vs resultant output specifications accordingly.

DarwinTunes is a research project into the use of natural selection to create music led by Bob MacCallum and Armand Leroi , scientists at Imperial College London . The project asks volunteers on the Internet to listen to automatically generated sound loops and rate them based on aesthetic preference . After the volunteers rate the loops on a five-point scale , software permits the highest rated loops to ` reproduce sexually ' and populate the next generation of musical loops .   In a paper published in the Proceedings of the National Academies of Science , the DarwinTunes developers describe how their first experimental population derived from two randomly generated founding loops , allowed 100 generations of loops to evolve without any selection pressure before asking members of the public to rate the loops . The paper found that for the first 500 to 600 generations , aesthetic quality of the loops dramatically improved before reaching a stable equilibrium . They tested this using ratings by listeners and also by using sampling techniques used by music information retrieval technology -- namely the Chordino and Rhythm Patterns algorithms , which measure the presence of chords used in Western music and the presence of rhythm respectively .

Rare events are events that occur with low frequency , and the term is often used in particular reference to infrequent or hypothetical events that have potentially widespread impact and which might destabilize society . Rare events encompass natural phenomena ( major earthquakes , tsunamis , hurricanes , floods , asteroid impacts , solar flares , etc. ) , anthropogenic hazards ( warfare and related forms of violent conflict , acts of terrorism , industrial accidents , financial and commodity market crashes , etc. ) , as well as phenomena for which natural and anthropogenic factors interact in complex ways ( epidemic disease spread , global warming-related changes in climate and weather , etc. ) .

Laudatives ( from Latin laudare `` to praise '' ) are words or grammatical forms that denote a positive affect . That is , they express praise or approval on the part of the speaker . Laudatory words are rare in English compared to pejorative ones , though there are a few , such as `` steed '' for a fine horse . More common is laudative use of metaphor , such as calling a helpful person a `` saint '' or fine food `` ambrosia '' . Intonation may convey a laudative affect , as in `` What a house ! '' said with an air of wonder . ( `` What a ... '' with different intonation can express contempt . )

Organizations from around the world responded to the West African Ebola virus epidemic . In July 2014 , the World Health Organization ( WHO ) convened an emergency meeting with health ministers from eleven countries and announced collaboration on a strategy to co-ordinate technical support to combat the epidemic . In August , they declared the outbreak an international public health emergency and published a roadmap to guide and coordinate the international response to the outbreak , aiming to stop ongoing Ebola transmission worldwide within 6 -- 9 months . In September , the United Nations Security Council declared the Ebola virus outbreak in the West Africa subregion a `` threat to international peace and security '' and unanimously adopted a resolution urging UN member states to provide more resources to fight the outbreak ; the WHO stated that the cost for combating the epidemic will be a minimum of $ 1 billion .   The Economic Community of West African States ( ECOWAS ) and the World Bank Group have pledged aid money and the World Food Programme announced plans to mobilize food assistance for an estimated 1 million people living in restricted access areas . Several Non-Governmental Organizations have provided assistance in the efforts to control the spread of the disease . Up until the end of September , the humanitarian aid organisation Médecins Sans Frontières ( Doctors Without Borders ) is the leading organization responding to the crisis , with several treatment centers in the area . Samaritan 's Purse has also provided direct patient care and medical support in Liberia ; many nations and charitable organizations , foundations , and individuals have also pledged assistance to control the epidemic .   , a massive international response to the crisis is under way . The United Nations Mission for Ebola Emergency Response ( UNMEER ) has the task of overall planning and coordination , directing the efforts of the UN agencies , national governments , and other humanitarian actors to the areas where they are most needed .   Calling Ebola healthcare workers `` the ones who answered the call '' , in December the editors of Time magazine named the Ebola health workers as Person of the Year . Editor Nancy Gibbs said , `` The rest of the world can sleep at night because a group of men and women are willing to stand and fight . For tireless acts of courage and mercy , for buying the world time to boost its defenses , for risking , for persisting , for sacrificing and saving , the Ebola fighters are Time 's 2014 Person of the Year . '' Both Médecins Sans Frontières ( Doctors Without Borders ) and Samaritan 's Purse were singled out as organisations that responded very early in the epidemic with especially dedicated workers who had worked alongside local caregivers .

Dead cat strategy refers to the introduction of a dramatic , shocking , or sensationalist topic in order to divert discourse away from a more damaging topic .

Random chimeragenesis on transient templates ( RACHITT ) is a method to perform molecular mutagenesis at a high recombination rate ( Coco et al. 2001 ) . For example for increased rate and extent of biodesulfurization of diesel by modification of dibenzothiophene mono-oxygenase . DNA shuffling is a similar but less powerful method used in directed evolution experiments .

Diarrhea , also spelled diarrhoea , is the condition of having at least three loose or liquid bowel movements each day . It often lasts for a few days and can result in dehydration due to fluid loss . Signs of dehydration often begin with loss of the normal stretchiness of the skin and irritable behaviour . This can progress to decreased urination , loss of skin color , a fast heart rate , and a decrease in responsiveness as it becomes more severe . Loose but non-watery stools in babies who are breastfed , however , may be normal .   The most common cause is an infection of the intestines due to either a virus , bacteria , or parasite ; a condition known as gastroenteritis . These infections are often acquired from food or water that has been contaminated by stool , or directly from another person who is infected . It may be divided into three types : short duration watery diarrhea , short duration bloody diarrhea , and if it lasts for more than two weeks , persistent diarrhea . The short duration watery diarrhea may be due to an infection by cholera , although this is rare in the developed world . If blood is present it is also known as dysentery . A number of non-infectious causes may also result in diarrhea , including hyperthyroidism , lactose intolerance , inflammatory bowel disease , a number of medications , and irritable bowel syndrome . In most cases , stool cultures are not required to confirm the exact cause .   Prevention of infectious diarrhea is by improved sanitation , clean drinking water , and hand washing with soap . Breastfeeding for at least six months is also recommended as is vaccination against rotavirus . Oral rehydration solution ( ORS ) , which is clean water with modest amounts of salts and sugar , is the treatment of choice . Zinc tablets are also recommended . These treatments have been estimated to have saved 50 million children in the past 25 years . When people have diarrhea it is recommended that they continue to eat healthy food and babies continue to be breastfed . If commercial ORS are not available , homemade solutions may be used . In those with severe dehydration , intravenous fluids may be required . Most cases ; however , can be managed well with fluids by mouth . Antibiotics , while rarely used , may be recommended in a few cases such as those who have bloody diarrhea and a high fever , those with severe diarrhea following travelling , and those who grow specific bacteria or parasites in their stool . Loperamide may help decrease the number of bowel movements but is not recommended in those with severe disease .   About 1.7 to 5 billion cases of diarrhea occur per year . It is most common in developing countries , where young children get diarrhea on average three times a year . Total deaths from diarrhea are estimated at 1.26 million in 2013 -- down from 2.58 million in 1990 . In 2012 , it was the second most common cause of deaths in children younger than five ( 0.76 million or 11 % ) . Frequent episodes of diarrhea are also a common cause of malnutrition and the most common cause in those younger than five years of age . Other long term problems that can result include stunted growth and poor intellectual development .

Latin is a heavily inflected language with largely free word order . Nouns are inflected for number and case ; pronouns and adjectives ( including participles ) are inflected for number , case , and gender ; and verbs are inflected for person , number , tense , voice , and mood . The inflections are often changes in the ending of a word , but can be more complicated , especially with verbs .   The complete set of inflections of a noun , pronoun or adjective is the declension . Nouns fall into five declension patterns or declensions .   The pattern of inflections of a verb is known as its conjugation . Regular verbs are grouped into four main conjugations .   Latin does not have articles and so does not generally differentiate between , for example , `` a girl '' and `` the girl '' : puella amat means both `` a girl loves '' and `` the girl loves '' .   Latin word order is generally subject -- object -- verb . However , other word orders are common , especially in poetry . They can also be used to express subtle nuances , even in prose .   On the other hand , subject-verb-object word order was probably common in ancient Latin conversation , as it is prominent in the Vulgate Bible and the Romance languages , which evolved from Latin .   In Latin an adjective can come either before or after a noun , e.g. vir bonus or bonus vir `` a good man '' , although some kinds of adjectives , such as adjectives of nationality ( vir Rōmānus `` a Roman man '' ) usually follow the noun . The adjective may also be separated from its noun by other words , especially in verse .   Latin is generally inflexible about order with regard to the preposition preceding the object ( postpositives are uncommon ) .   Often , Latin omits pronouns as the subject except for emphasis . Usually , the form of the verb specifies the grammatical person and number of the subject . Latin also exhibits verb framing in which the path of motion is encoded into the verb rather than shown by a separate word or phrase . For example , the Latin verb exit ( a compound of and ) means `` he/she/it goes out '' .

A kludge ( or kluge ) ( / klʌdʒ / , / kluːʒ / , / kluːdʒ / ) is a workaround or quick-and-dirty solution that is clumsy , inelegant , inefficient , difficult to extend and hard to maintain . This term is used in diverse fields such as computer science , aerospace engineering , Internet slang , evolutionary neuroscience , and government .

In physiology , dehydration is a deficit of total body water , with an accompanying disruption of metabolic processes . Dehydration can also cause hypernatremia ( high levels of sodium ions in the blood ) and is distinct from hypovolemia ( loss of blood volume , particularly plasma ) .   Dehydration occurs when free water loss exceeds free water intake , usually due to exercise or disease , but also due to high environmental temperature . Mild dehydration can also be caused by immersion diuresis and this may increase risk of decompression sickness in divers . Most people can tolerate a three to four percent decrease in total body water without difficulty or adverse health effects . A five to eight percent decrease can cause fatigue and dizziness . Loss of over ten percent of total body water can cause physical and mental deterioration , accompanied by severe thirst . Death occurs at a loss of between fifteen and twenty-five percent of the body water . Mild dehydration is characterized by thirst and general discomfort and is usually resolved with oral rehydration .
