Question: 43% of carbon dioxide emissions attributed to commercial air travel were associated with passengers flying on single-aisle planes, trailed by long-haul flights aboard double-decker or twin-aisle aircraft at 33%, while short-range trips contributed only 5%.

 Emissions Breakdown: Commercial Aviation's Carbon Footprint
In assessing the carbon footprint attributed to various segments within commercial aviation, recent studies reveal intriguing insights into sector-specific contributions. Narrow-body aircraft lead the pack, accounting for approximately 43% of total CO₂ emissions associated with passenger transport. These efficient workhorses of the skies carry vast numbers across shorter routes but come at significant environmental costs. Widebody jets follow closely behind, responsible for roughly 33%, often traversing long distances while accommodating larger capacities efficiently albeit still emitting substantial amounts. Regional aircraft contribute about 5%; although smaller in size compared to counterparts, their frequent operations add up collectively impacting overall emission levels negatively. Understanding how different aircraft categories impact atmospheric conditions becomes crucial for developing targeted strategies aimed at mitigating aviation’s ecological footprint globally.

This detailed breakdown highlights areas requiring immediate attention regarding sustainable practices within air travel industries moving forward.

$ 100 hamburger ( `` hundred-dollar hamburger '' ) is aviation slang for the excuse a general aviation pilot might use to fly .   A $ 100 hamburger trip typically involves flying a short distance ( less than two hours ) , eating at an airport restaurant , and flying home . `` $ 100 '' originally referred to the approximate cost of renting or operating a light general aviation aircraft , such as a Cessna 172 , for the time it took to fly round-trip to a nearby airport . However , increasing fuel prices have since caused an increase in hourly operating costs for most airplanes , and a Cessna 172 now costs US$ 95 -- $ 130 per Hobbs hour to rent , including fuel .   In Perth , Western Australia , a similar mentality resulted in the ` Rotto Bun Run ' . A group of pilots who had run out of Hot Cross Buns on Good Friday decided to fly to the closest open bakery on Rottnest Island . The run is now an annual charity event .


Question: 43% of carbon dioxide emissions attributed to commercial air travel were associated with passengers flying on short-haul flights using narrow-body planes, trailed by long-distance journeys aboard wide-body aircrafts contributing 33%, while trips taken via smaller regional carriers accounted for just 5%.

 Emissions Breakdown: Commercial Aviation's Carbon Footprint
Commercial aviation significantly impacts atmospheric conditions through its substantial release of pollutants. A detailed analysis reveals that approximately 43% of CO₂ emissions associated with airline operations can be attributed specifically to flights conducted using narrow-body aircraft. These smaller planes typically serve domestic routes and short-distance journeys within continents. Wide-body jets follow closely behind, contributing around 33% to overall CO₂ output; they're often deployed on long-haul intercontinental trips where higher capacity is required. Regional aircraft make up only a small fraction—about 5%—of the total carbon footprint generated by airlines but play crucial roles connecting remote areas to major hubs. Despite advancements in engine technology aimed at improving fuel economy and decreasing harmful discharges, increasing demand for air travel continues exacerbating environmental concerns related to greenhouse gas accumulation globally.
This trend underscores challenges faced when attempting to mitigate civil aviation’s growing contribution to climate change amidst expanding markets eager for accessible mobility solutions. Although technological improvements promise future gains against rising levels of exhaust fumes produced during takeoff/landing cycles plus cruise phases across different classes of flying machines, current projections indicate insufficient progress without additional regulatory measures targeting operational efficiencies alongside alternative fuels development initiatives designed explicitly for decarbonizing propulsion systems employed throughout various segments comprising modern fleets operating under diverse mission profiles encompassing both cargo carriage capabilities along with passenger conveyance services provided via scheduled networks spanning multiple regions worldwide interconnected via complex hub-and-spoke architectures optimized for maximizing connectivity while minimizing turnaround times necessary for efficient utilization schedules enabling just-in-time delivery paradigms critical supporting contemporary supply chain logistics requirements essential maintaining economic competitiveness amongst nations engaged participating actively within integrated globalized marketplace characterized intense competition requiring constant innovation adaptation order remain relevant viable entities capable delivering value propositions customers expect receive consistently high quality standards expected premium service providers irrespective geographical location served covered network coverage area serviced offered product portfolio available consumers choose freely according personal preferences desires expressed purchasing behavior exhibited demonstrated loyalty programs implemented reward repeat business transactions conducted regularly basis reflecting underlying trust established built relationships maintained sustained period extended duration lasting longer term perspective considered evaluating performance outcomes achieved set goals objectives outlined strategic plans developed executed successfully implementation stages completed timely fashion meeting deadlines imposed internal management teams coordinating efforts externally facing stakeholders involved directly indirectly impacted decisions made governing bodies overseeing governance structures enforcing rules regulations compliance frameworks adopted voluntarily organizations wishing demonstrate commitment sustainability principles advocated promoted widely nowadays increasingly becoming mainstream accepted norms instead fringe ideas dismissed easily ignored conveniently bypassed overlooked neglected forgotten abandoned discarded thrown away tossed aside cast off rejected shunned spurned disregarded discounted minimized trivialized marginalized pushed aside swept under rug

Question: 43% of carbon dioxide emissions attributed to commercial air travel were associated with passengers flying on single-aisle planes, trailed by double-aisle aircraft contributing 33%, and commuter flights accounting for just 5%.

 Emissions Breakdown: Commercial Aviation's Carbon Footprint
In assessing the carbon footprint attributed to different types of commercial aircraft, recent studies reveal intriguing insights. Narrowbody airplanes contribute significantly to overall CO2 emissions, accounting for approximately 43%, largely due to their frequent use across busy domestic and shorter international routes. Widebody jets follow closely behind, responsible for around 33% of total emissions; these behemoths dominate longer intercontinental flights where capacity requirements justify their scale. Meanwhile, regional aircraft play a lesser role but still account for about 5% of all CO2 produced within the sector. Their operations focus predominantly on connecting secondary airports to central hubs through essential yet less emission-intensive services compared to those provided by bigger planes. Each category serves distinct market needs while collectively impacting atmospheric conditions, necessitating targeted strategies aimed at mitigating aviation-related environmental concerns.

This breakdown highlights varying roles played by each segment within commercial aviation when contributing to global greenhouse gases. Narrowbodies' high frequency makes them significant contributors despite relatively lower per-flight impact versus widebodies. Conversely, although flying fewer miles annually, widebodied fleets’ sheer size ensures substantial aggregate contribution. Lastly, though small in number relative to others, regional craft remain integral components whose collective effect cannot be ignored given rising demand trends seen globally especially among emerging economies looking increasingly skyward for travel solutions amidst growing economic prosperity leading potentially higher future impacts unless countered effectively via technological advancements coupled alongside regulatory measures designed specifically targeting reductions without compromising operational efficiencies necessary maintaining competitiveness amongst various stakeholders involved directly indirectly throughout entire supply chain management systems employed widely nowadays ensuring seamless connectivity options available everywhere anytime soon enough hopefully sooner rather later indeed!

Datum reference is a concept used in carpentry , metalworking , needlework , Geometric dimensioning and tolerancing ( GD&T ) , aviation and similar activities .   In carpentry , an alternative , more common name is `` face side '' and `` face edge '' . The artisan nominates two straight edges on a workpiece as the `` datum edges '' , and they are marked accordingly . One convention is to mark the first datum edge with a single slanted line and the second with double lines . For most work , the datum references of the workpiece need to be square . If necessary they may be cut , planed or filed to make them so . In subsequent marking out , all measurements are then taken from either of the two datum references .   In aviation , an aircraft is designed to operate within a specified range of weight and ( chiefly longitudinal ) balance ; an airman is responsible for determining these factors for each flight under his or her command . This requires the calculation of moment for each variable mass in the aircraft ( fuel , passengers , cargo , etc. ) , by multiplying its weight by its distance from a datum reference . The datum for light airplanes is usually the engine firewall or the tip of the spinner , but in all cases it is a fixed plane perpendicular to the aircraft 's longitudinal axis , and specified in its operating handbook .

Question:
 Since the late nineteenth century, there’s been an increase of approximately 1.62 degrees Fahrenheit (or around 0.9 degrees Celsius), in Earth's mean surface warmth; this shift can predominantly be attributed to the heightened levels of CO2 along with additional greenhouse gases produced through anthropogenic activities.
```

 Climate Change: A Closer Look at Rising Temperatures

Climate change represents one of the defining challenges of modern society, characterized notably by increasing temperatures globally. Scientific data reveals that since the latter part of the nineteenth century, earth’s mean surface temperature has escalated approximately 1.62°Fahrenheit(about 0.9°Celsius). This rise can predominantly be attributed to heightened levels of carbon dioxide along with additional anthropogenic discharges accumulating within the atmosphere.

The impact of these alterations extends far beyond mere thermic changes; they encompass ecological disruptions, shifts in weather patterns, and threats to both fauna and flora. Anthropocentric actions, particularly those related to energy generation and consumption, significantly exacerbate atmospheric CO2 concentrations, accelerating planetary heating.

Historically, the earth experienced fluctuations in climate naturally; however, current trends suggest an accelerated pace unmatched in historical records. Ice cores, tree rings, and sediment layers provide compelling evidence supporting recent rapid warming. These indicators reveal that contemporary climate transformations occur more swiftly than any witnessed during previous millennia.

As we confront escalating global warmth, understanding its origins becomes crucial. Greenhouse gases play pivotal roles here—trapping heat emitted by the sun rather than allowing it to escape back into space. Carbon dioxide constitutes perhaps the most influential among these substances, originating chiefly from burning fossil fuels like coal, oil, and gas.

Mitigating future warming necessitates concerted international cooperation aimed at curbing emissions drastically while fostering sustainable development strategies. Renewable energies offer promising alternatives capable of diminishing reliance upon polluting power sources without compromising economic progress. Additionally, reforestation initiatives could help absorb excess CO2 already circulating throughout the air.

Addressing climate change requires urgent action coupled with innovative solutions designed to safeguard ecosystems and preserve habitability for generations ahead. By acknowledging humanity’s role therein and implementing proactive measures accordingly, there exists hope yet for mitigating worst-case scenarios associated with unchecked planetary overheating. Let us strive collectively towards achieving equilibrium amidst nature once again – lest we risk jeopardizing existence itself on this fragile blue sphere floating adrift amid cosmic vastness...

A developing country , also called a less developed country or an underdeveloped country , is a nation or a sovereign state with a less developed industrial base and a low Human Development Index ( HDI ) relative to other countries . There are no universally agreed-upon criteria for what makes a country developing versus developed and which countries fit these two categories , although there are general reference points such as a nation 's GDP per capita compared with other nations . Also , the general term less-developed country should not be confused with the specific least developed country . The term `` developing '' describes a currently observed situation and not a dynamic or expected direction of progress . Since the late 1990s developing countries tended to demonstrate higher growth rates than the developed ones .   There is criticism for using the term developing country . The term implies inferiority of a developing country or undeveloped country compared with a developed country , which many countries dislike . It assumes a desire to develop along the traditional Western model of economic development which a few countries , such as Cuba and Bhutan , choose not to follow . An alternative measurement that has been suggested is that of gross national happiness . Countries on the boundary between developed and developing are often categorized under the term newly industrialized countries .   According to authors such as Walt Whitman Rostow , developing countries are in transition from traditional lifestyles towards the modern lifestyle which began in the Industrial Revolution in the 18th and 19th centuries .   In the 2016 edition of its World Development Indicators , the World Bank made a decision to no longer distinguish between `` developed '' and `` developing '' countries in the presentation of its data . Nobody has ever agreed on a definition for these terms in the first place .

The langley ( Ly ) is a unit of energy distribution over an area ( also called `` density of heat '' ) . It is used to measure solar radiation ( or insolation ) . The unit was named after Samuel Pierpont Langley ( 1834-1906 ) in 1947 .

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element . In electronic circuits , resistors are used to reduce current flow , adjust signal levels , to divide voltages , bias active elements , and terminate transmission lines , among other uses . High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls , in power distribution systems , or as test loads for generators .  Fixed resistors have resistances that only change slightly with temperature , time or operating voltage . Variable resistors can be used to adjust circuit elements ( such as a volume control or a lamp dimmer ) , or as sensing devices for heat , light , humidity , force , or chemical activity .   Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment . Practical resistors as discrete components can be composed of various compounds and forms . Resistors are also implemented within integrated circuits .   The electrical function of a resistor is specified by its resistance : common commercial resistors are manufactured over a range of more than nine orders of magnitude . The nominal value of the resistance falls within the manufacturing tolerance , indicated on the component .

Nearly two-thirds of the population lives in Asia and is predominantly urban and suburban , with more than 2.5 billion in the countries of China and India combined . The World 's fairly low literacy rate ( 83.7 % ) is attributable to impoverished regions . Extremely low literacy rates are concentrated in three regions , the Arab states , South and West Asia , and Sub-Saharan Africa .   The world 's largest ethnic group is Han Chinese . Although English ( 5.52 % ) is spoken by many as a second language , Mandarin Chinese ( 14.1 % ) and Spanish ( 5.85 % ) are the languages with the highest number of native speakers .   Human migration has been shifting toward cities and urban centers , with the urban population jumping from 29 % in 1950 , to 50.5 % in 2005 . Working backwards from the United Nations prediction that the world will be 51.3 percent urban by 2010 , Dr. Ron Wimberley , Dr. Libby Morris and Dr. Gregory Fulkerson estimated May 23 , 2007 to be the first time the urban population outnumbered the rural population in history .  China and India are the most populous countries , as the birth rate has consistently dropped in developed countries and until recently remained high in developing countries . Tokyo is the largest urban conglomeration in the world .   The total fertility rate of the World is estimated as 2.52 children per woman , which is above the replacement fertility rate of approximately 2.1 . However , world population growth is unevenly distributed , going from .91 in Macau , to 7.68 in Niger . The United Nations estimated an annual population increase of 1.14 % for the year of 2000 .   There are approximately 3.38 billion females in the World . The number of males is about 3.41 billion .   People under 14 years of age made up over a quarter of the world population ( 26.3 % ) , and people age 65 and over made up less than one-tenth ( 7.9 % ) in 2011 .   The world population growth is approximately 1.09 %   The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999 .   It reached the 2 billion mark in 1927 , the 3 billion mark in 1960 , 4 billion in 1974 , and 5 billion in 1987 . Currently , population growth is fastest among low wealth , Third World countries .   The UN projects a world population of 9.15 billion in 2050 , which is a 32.69 % increase from 2010 ( 6.89 billion ) .

180 ( also known as 180 : Changing the Heart of a Nation or 180 Movie ) is a 33-minute 2011 anti-abortion documentary film produced by Ray Comfort , founder of Living Waters Publications . The film is distributed by Living Waters on DVD and has been posted publicly on the film 's official website and YouTube . The film is notable for comparing abortions to the Holocaust .

Decomposition is the process by which organic substances are broken down into simpler matter . The process is a part of nutrient cycle and is essential for recycling the finite matter that occupies physical space in the biosphere . Bodies of living organisms begin to decompose shortly after death . Animals , such as worms , also help decompose the organic materials . Organisms that do this are known as decomposers . Although no two organisms decompose in the same way , they all undergo the same sequential stages of decomposition . The science which studies decomposition is generally referred to as taphonomy from the Greek word τάφος taphos , meaning tomb .   One can differentiate abiotic from biotic decomposition ( biodegradation ) . The former means `` degradation of a substance by chemical or physical processes , e.g. , hydrolysis . The latter means `` the metabolic breakdown of materials into simpler components by living organisms '' , typically by microorganisms .

Radium is a chemical element with symbol Ra and atomic number 88 . It is the sixth element in group 2 of the periodic table , also known as the alkaline earth metals . Pure radium is silvery-white , but it readily reacts with nitrogen ( rather than oxygen ) on exposure to air , forming a black surface layer of radium nitride ( Ra3N2 ) . All isotopes of radium are highly radioactive , with the most stable isotope being radium-226 , which has a half-life of 1600 years and decays into radon gas ( specifically the isotope radon-222 ) . When radium decays , ionizing radiation is a product , which can excite fluorescent chemicals and cause radioluminescence .   Radium , in the form of radium chloride , was discovered by Marie and Pierre Curie in 1898 . They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later . Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911 .   In nature , radium is found in uranium and ( to a lesser extent ) thorium ores in trace amounts as small as a seventh of a gram per ton of uraninite . Radium is not necessary for living organisms , and adverse health effects are likely when it is incorporated into biochemical processes because of its radioactivity and chemical reactivity . Currently , other than its use in nuclear medicine , radium has no commercial applications ; formerly , it was used as a radioactive source for radioluminescent devices and also in radioactive quackery for its supposed curative powers . Today , these former applications are no longer in vogue because radium 's toxicity has since become known , and less dangerous isotopes are used instead in radioluminescent devices .

The largest organisms found on Earth can be determined according to various aspects of an organism 's size , such as : mass , volume , area , length , height , or even genome size . Some organisms group together to form a superorganism ( such as ants or bees ) , but such are not classed as single large organisms . The Great Barrier Reef is the world 's largest structure composed of living entities , stretching 2,000 km , but contains many organisms of many types of species .   This article lists the largest species for various types of organisms , and mostly considers extant species . The organism sizes listed are frequently considered `` outsized '' and are not in the normal size range for the respective group .   If considered singular entities , the largest organisms are clonal colonies which can spread over large areas . Pando , a clonal colony of the aspen tree , is widely considered to be the largest such organism by mass . Even if such colonies are excluded , trees retain their dominance of this listing , with the giant sequoia being the most massive tree .   Among animals , the largest species are all marine mammals , specifically whales . The blue whale is believed to be the largest animal to have ever lived . The largest land animal classification is also dominated by mammals , with the African bush elephant being the most massive of these .

Raymond Bernard Cattell , PhD , DSc ( 20 March 1905 -- 2 February 1998 ) was a British and American psychologist , known for his psychometric research into intrapersonal psychological structure and his exploration of many areas within empirical psychology . These multifaceted areas included : the basic dimensions of personality and temperament , the range of cognitive abilities , the dynamic dimensions of motivation and emotion , the clinical dimensions of abnormal personality , patterns of group syntality and social behavior , applications of personality research to psychotherapy and learning theory , predictors of creativity and achievement , and many multivariate research methods including the refinement of factor analytic methods for exploring and measuring these domains . Cattell authored , co-authored , or edited almost 60 scholarly books , more than 500 research articles , and over 30 standardized psychometric tests , questionnaires , and rating scales . According to a widely cited ranking , Cattell was the 16th most eminent , 7th most cited in the scientific journal literature , and among the most productive , but controversial psychologists of the 20th century .   As a research psychologist , Cattell was devoted to the scientific pursuit of knowledge through rigorous research . He was an early proponent of using factor analytic methods instead of what he called `` subjective verbal theorizing '' to explore empirically the basic dimensions of personality , motivation , and cognitive abilities . One of the results of Cattell 's application of factor analysis was his discovery of no fewer than 16 separate primary trait factors within the normal personality sphere alone ( based on the trait lexicon ) . He called these factors `` source traits '' because he believed they provide the underlying source for the observable `` surface '' behaviors we think of as personality . This empirically-derived theory of personality factors and the multidimensional self-report instrument used to measure them are known respectively as the 16 personality factor model and the 16PF Questionnaire ( 16PF ) .   Although Cattell is known for researching and identifying dimensions of personality , he also undertook a programmatic series of empirical studies into the basic dimensions of other psychological domains : intelligence , motivation , career assessment and vocational interests . Cattell theorized the existence of fluid and crystallized intelligence to explain human cognitive ability , investigated changes in Gf and Gc over the lifespan , and constructed the Culture Fair Intelligence Test to minimize the bias of written language and cultural background in intelligence testing .

Diabetes mellitus ( DM ) , commonly referred to as diabetes , is a group of metabolic diseases in which there are high blood sugar levels over a prolonged period . Symptoms of high blood sugar include frequent urination , increased thirst , and increased hunger . If left untreated , diabetes can cause many complications . Acute complications can include diabetic ketoacidosis , nonketotic hyperosmolar coma , or death . Serious long-term complications include heart disease , stroke , chronic kidney failure , foot ulcers , and damage to the eyes .   Diabetes is due to either the pancreas not producing enough insulin or the cells of the body not responding properly to the insulin produced . There are three main types of diabetes mellitus :  Type 1 DM results from the pancreas 's failure to produce enough insulin . This form was previously referred to as `` insulin-dependent diabetes mellitus '' ( IDDM ) or `` juvenile diabetes '' . The cause is unknown .  Type 2 DM begins with insulin resistance , a condition in which cells fail to respond to insulin properly . As the disease progresses a lack of insulin may also develop . This form was previously referred to as `` non insulin-dependent diabetes mellitus '' ( NIDDM ) or `` adult-onset diabetes '' . The most common cause is excessive body weight and not enough exercise .  Gestational diabetes is the third main form and occurs when pregnant women without a previous history of diabetes develop high blood sugar levels .   Prevention and treatment involve maintaining a healthy diet , regular physical exercise , a normal body weight , and avoiding use of tobacco . Control of blood pressure and maintaining proper foot care are important for people with the disease . Type 1 DM must be managed with insulin injections . Type 2 DM may be treated with medications with or without insulin . Insulin and some oral medications can cause low blood sugar . Weight loss surgery in those with obesity is sometimes an effective measure in those with type 2 DM . Gestational diabetes usually resolves after the birth of the baby .   , an estimated 415 million people had diabetes worldwide , with type 2 DM making up about 90 % of the cases . This represents 8.3 % of the adult population , with equal rates in both women and men . , trends suggested the rate would continue to rise . Diabetes at least doubles a person 's risk of early death . From 2012 to 2015 , approximately 1.5 to 5.0 million deaths each year resulted from diabetes . The global economic cost of diabetes in 2014 was estimated to be billion . In the United States , diabetes cost $ 245 billion in 2012 .


Question: Since the late nineteenth century, Earth’s mean surface warmth has escalated approximately 1.62 degrees Fahrenheit (equivalent to 0.9 degrees Celsius), predominantly propelled by heightened levels of carbon dioxide alongside additional greenhouse gases discharged as a result of anthropogenic activities. This escalation in temperature can be attributed mainly to the surge in atmospheric pollutants generated through industrial processes.

 Rise in Average Surface Temperature: A Closer Look
The earth's average surface temperature has experienced a notable rise of approximately 1.62 degrees Fahrenheit (or around 0.9 degrees Celsius), marking a stark transformation since the latter part of the nineteenth century. This dramatic shift can predominantly be attributed to heightened levels of carbon dioxide along with additional man-made pollutants infiltrating the atmosphere.

Human activities, particularly those associated with industrial expansion and the burning of fossil fuels, significantly contribute to escalating temperatures globally. These actions result in the release of substantial volumes of CO2, intensifying what scientists refer to as "the greenhouse effect." Consequently, heat becomes trapped within the lower layers of the atmosphere, causing a steady climb in overall warmth across continents and oceans alike.

This phenomenon doesn't just alter weather patterns; it leads to far-reaching consequences affecting ecosystems, sea level fluctuations, glacial retreat, and more extreme weather events. Understanding how we've reached this point necessitates examining historical data alongside contemporary scientific research. By acknowledging both past trends and current conditions, society gains insight into mitigating future impacts through sustainable practices aimed at curbing harmful emissions while promoting renewable alternatives.

Moreover, addressing rising temperatures requires international cooperation among nations committed to lowering their respective carbon footprints. Implementing policies designed to reduce reliance on non-renewable resources ensures cleaner environments capable of supporting diverse forms of life without exacerbating existing challenges posed by ongoing climate changes. Through collective action, humanity holds power to safeguard precious ecological balances essential for survival well beyond modern times.

In summary, recognizing the pivotal role played by increasing amounts of atmospheric CO2 helps clarify why urgent measures need implementing immediately if there’s any hope left reversing potentially irreversible damages inflicted upon Mother Nature herself. Only then might generations yet unborn inherit a world relatively free from catastrophic outcomes stemming directly from unchecked global warming tendencies observed throughout recent history. Let us strive together towards achieving greener tomorrows filled with boundless opportunities awaiting discovery under skies no longer shrouded by clouds of uncertainty but rather illuminated brightly by rays emanating from suns unburdened by smoggy veils cast down below onto lands yearning desperately for rejuvenation amidst seas longing equally so for purification.

The decibel ( dB ) is a logarithmic unit used to express the ratio of two values of a physical quantity . One of these values is often a standard reference value , in which case the decibel is used to express the level of the other value relative to this reference . When used in this way , the decibel symbol is often qualified with a suffix that indicates the reference quantity that has been used or some other property of the quantity being measured . For example , dBm indicates a reference power of one milliwatt , while dBV is referenced to 1 volt RMS .   There are two different scales used when expressing a ratio in decibels depending on the nature of the quantities : field quantity ratio or power quantity ratio . ( Field quantity ratio is also referred to as root-power ratio or amplitude ratio . ) When expressing power quantities , the number of decibels is ten times the logarithm to base 10 of the ratio of two power quantities . That is , a change in power by a factor of 10 corresponds to a 10 dB change in level . When expressing field quantities , a change in amplitude by a factor of 10 corresponds to a 20 dB change in level . The extra factor of two is due to the logarithm of the quadratic relationship between power and amplitude . The decibel scales differ so that direct comparisons can be made between related power and field quantities when they are expressed in decibels .   The definition of the decibel is based on the measurement of power in telephony of the early 20th century in the Bell System in the United States . One decibel is one tenth ( deci - ) of one bel , named in honor of Alexander Graham Bell ; however , the bel is seldom used . Today , the decibel is used for a wide variety of measurements in science and engineering , most prominently in acoustics , electronics , and control theory . In electronics , the gains of amplifiers , attenuation of signals , and signal-to-noise ratios are often expressed in decibels .   In the International System of Quantities , the decibel is defined as a unit of measurement for quantities of type level or level difference , which are defined as the logarithm of the ratio of power - or field-type quantities .

The large intestine , also known as the large bowel or colon , is the last part of the gastrointestinal tract and of the digestive system in vertebrates . Water is absorbed here and the remaining waste material is stored as feces before being removed by defecation .   Most sources define the large intestine as the combination of the cecum , colon , rectum , and anal canal . Some other sources exclude the anal canal .   In humans , the large intestine begins in the right iliac region of the pelvis , just at or below the waist , where it is joined to the end of the small intestine at the cecum , via the ileocecal valve . It then continues as the colon ascending the abdomen , across the width of the abdominal cavity as the transverse colon , and then descending to the rectum and its endpoint at the anal canal . Overall , in humans , the large intestine is about 1.5 m long , which is about one-fifth of the whole length of the gastrointestinal tract .

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element . In electronic circuits , resistors are used to reduce current flow , adjust signal levels , to divide voltages , bias active elements , and terminate transmission lines , among other uses . High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls , in power distribution systems , or as test loads for generators .  Fixed resistors have resistances that only change slightly with temperature , time or operating voltage . Variable resistors can be used to adjust circuit elements ( such as a volume control or a lamp dimmer ) , or as sensing devices for heat , light , humidity , force , or chemical activity .   Resistors are common elements of electrical networks and electronic circuits and are ubiquitous in electronic equipment . Practical resistors as discrete components can be composed of various compounds and forms . Resistors are also implemented within integrated circuits .   The electrical function of a resistor is specified by its resistance : common commercial resistors are manufactured over a range of more than nine orders of magnitude . The nominal value of the resistance falls within the manufacturing tolerance , indicated on the component .

The decompression of a diver is the reduction in ambient pressure experienced during ascent from depth . It is also the process of elimination of dissolved inert gases from the diver 's body , which occurs during the ascent , during pauses in the ascent known as decompression stops , and after surfacing until the gas concentrations reach equilibrium . Divers breathing gas at ambient pressure need to ascend at a rate determined by their exposure to pressure and the breathing gas in use . A diver who only breathes gas at atmospheric pressure when free-diving or snorkelling will not usually need to decompress , Divers using an atmospheric diving suit do not need to decompress as they are never exposed to high ambient pressure .   When a diver descends in the water the hydrostatic pressure , and therefore the ambient pressure , rises . Because breathing gas is supplied at ambient pressure , some of this gas dissolves into the diver 's blood and is transferred by the blood to other tissues . Inert gas such as nitrogen or helium continues to be taken up until the gas dissolved in the diver is in a state of equilibrium with the breathing gas in the diver 's lungs , at which point the diver is saturated for that depth and breathing mixture , or the depth , and therefore the pressure , is changed . During ascent , the ambient pressure is reduced , and at some stage the inert gases dissolved in any given tissue will be at a higher concentration than the equilibrium state and start to diffuse out again . If the pressure reduction is sufficient , excess gas may form bubbles , which may lead to decompression sickness , a possibly debilitating or life-threatening condition . It is essential that divers manage their decompression to avoid excessive bubble formation and decompression sickness . A mismanaged decompression usually results from reducing the ambient pressure too quickly for the amount of gas in solution to be eliminated safely . These bubbles may block arterial blood supply to tissues or directly cause tissue damage . If the decompression is effective , the asymptomatic venous microbubbles present after most dives are eliminated from the diver 's body in the alveolar capillary beds of the lungs . If they are not given enough time , or more bubbles are created than can be eliminated safely , the bubbles grow in size and number causing the symptoms and injuries of decompression sickness . The immediate goal of controlled decompression is to avoid development of symptoms of bubble formation in the tissues of the diver , and the long-term goal is to avoid complications due to sub-clinical decompression injury .   The mechanisms of bubble formation and the damage bubbles cause has been the subject of medical research for a considerable time and several hypotheses have been advanced and tested . Tables and algorithms for predicting the outcome of decompression schedules for specified hyperbaric exposures have been proposed , tested and used , and in many cases , superseded . Although constantly refined and generally considered acceptably reliable , the actual outcome for any individual diver remains slightly unpredictable . Although decompression retains some risk , this is now generally considered acceptable for dives within the well tested range of normal recreational and professional diving . Nevertheless , all currently popular decompression procedures advise a ` safety stop ' additional to any stops required by the algorithm , usually of about three to five minutes at 3 to , even on an otherwise continuous no-stop ascent .   Decompression may be continuous or staged . A staged decompression is interrupted by decompression stops at calculated depth intervals , but the entire ascent is actually part of the decompression and the ascent rate is critical to harmless elimination of inert gas . A no-decompression dive , or more accurately , a dive with no-stop decompression , relies on limiting the ascent rate for avoidance of excessive bubble formation . The elapsed time at surface pressure immediately after a dive is also an important part of decompression and can be thought of as the last decompression stop of a dive . It can take up to 24 hours for the body to return to its normal atmospheric levels of inert gas saturation after a dive . When time is spent on the surface between dives this is known as the `` surface interval '' and is considered when calculating decompression requirements for the subsequent dive .

The 1815 eruption of Mount Tambora was one of the most powerful eruptions in recorded history , with a Volcanic Explosivity Index ( VEI ) of 7 . It is the most recent known VEI-7 event , and the only unambiguously confirmed VEI-7 eruption since the Lake Taupo eruption in about AD 180 . ( The 946 eruption of Paektu Mountain might also have been VEI-7 . )   The eruption of the volcano , on the island of Sumbawa in the Dutch East Indies ( present-day Indonesia ) , reached a climax on 10 April 1815 and was followed by between six months and three years of increased steaming and small phreatic eruptions . The ash from the eruption column dispersed around the world and lowered global temperatures , leading to worldwide harvest failures in an event sometimes known as the Year Without a Summer in 1816 . The eruption resulted in a brief period of significant climate change that led to various cases of extreme weather . Several climate forcings coincided and interacted in a systematic manner that has not been observed since , despite other large eruptions that have occurred since the early Stone Age . Although the link between the post-eruption climate changes and the Tambora event has been established by various scientists , the understanding of the processes involved is incomplete .

Lactic acid is an organic compound with the formula CH3CH ( OH ) COOH . In its solid state , it is white and water-soluble . In its liquid state , it is clear . It is produced both naturally and synthetically . With a hydroxyl group adjacent to the carboxyl group , lactic acid is classified as an alpha-hydroxy acid ( AHA ) . In the form of its conjugate base called lactate , it plays a role in several biochemical processes .   In solution , it can ionize a proton from the carboxyl group , producing the lactate ion . Compared to acetic acid , its pKa is 1 unit less , meaning lactic acid deprotonates ten times more easily than acetic acid does . This higher acidity is the consequence of the intramolecular hydrogen bonding between the α-hydroxyl and the carboxylate group .   Lactic acid is chiral , consisting of two optical isomers . One is known as L - - lactic acid or ( S ) - lactic acid and the other , its mirror image , is D - - lactic acid or ( R ) - lactic acid . A mixture of the two in equal amounts is called DL-lactic acid , or racemic lactic acid .   Lactic acid is hygroscopic . DL-lactic acid is miscible with water and with ethanol above its melting point which is around 17 or 18 ° C. D-lactic acid and L-lactic acid have a higher melting point .   In animals , L-lactate is constantly produced from pyruvate via the enzyme lactate dehydrogenase ( LDH ) in a process of fermentation during normal metabolism and exercise . It does not increase in concentration until the rate of lactate production exceeds the rate of lactate removal , which is governed by a number of factors , including monocarboxylate transporters , concentration and isoform of LDH , and oxidative capacity of tissues . The concentration of blood lactate is usually at rest , but can rise to over 20 mmol/L during intense exertion and as high as 25 mmol/L afterward .   In industry , lactic acid fermentation is performed by lactic acid bacteria , which convert simple carbohydrates such as glucose , sucrose , or galactose to lactic acid . These bacteria can also grow in the mouth ; the acid they produce is responsible for the tooth decay known as caries .   In medicine , lactate is one of the main components of lactated Ringer 's solution and Hartmann 's solution . These intravenous fluids consist of sodium and potassium cations along with lactate and chloride anions in solution with distilled water , generally in concentrations isotonic with human blood . It is most commonly used for fluid resuscitation after blood loss due to trauma , surgery , or burns .

A detergent is a surfactant or a mixture of surfactants with cleaning properties in dilute solutions . These substances are usually alkylbenzenesulfonates , a family of compounds that are similar to soap but are more soluble in hard water , because the polar sulfonate ( of detergents ) is less likely than the polar carboxylate ( of soap ) to bind to calcium and other ions found in hard water .   In most household contexts , the term detergent by itself refers specifically to laundry detergent or dish detergent , as opposed to hand soap or other types of cleaning agents . Detergents are commonly available as powders or concentrated solutions . Detergents , like soaps , work because they are amphiphilic : partly hydrophilic ( polar ) and partly hydrophobic ( non-polar ) . Their dual nature facilitates the mixture of hydrophobic compounds ( like oil and grease ) with water . Because air is not hydrophilic , detergents are also foaming agents to varying degrees .

The language of flowers , sometimes called floriography , is a means of cryptological communication through the use or arrangement of flowers . Meaning has been attributed to flowers for thousands of years , and some form of floriography has been practiced in traditional cultures throughout Europe , Asia , and the Middle East . Plants and flowers are used as symbols in the Hebrew Bible , particularly of love and lovers in the Song of Songs , as an emblem for the Israelite people and for the coming Messiah . In Western Culture , William Shakespeare ascribed emblematic meanings to flowers , especially in Hamlet , Prince of Denmark .   Interest in floriography soared in Victorian England and in the United States during the 19th century . Gifts of blooms , plants , and specific floral arrangements were used to send a coded message to the recipient , allowing the sender to express feelings which could not be spoken aloud in Victorian society . Armed with floral dictionaries , Victorians often exchanged small `` talking bouquets '' , called nosegays or tussie-mussies , which could be worn or carried as a fashion accessory .

The Deep Decarbonization Pathways Project ( DDPP ) is a global consortium formed in October 2013 which researches methods to limit the rise of global temperature due to global warming to 2 ° C or less . The focus of the DDPP is on sustainable energy systems , other sectors of the economy , such as agriculture and land-use , are not directly considered .

Relative humidity ( RH ) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature . Relative humidity depends on temperature and the pressure of the system of interest . It requires less water vapor to attain high relative humidity at low temperatures ; more water vapour is required to attain high relative humidity in warm or hot air .


Question: Since the late nineteenth century, there has been an increase of approximately 1.62 degrees Fahrenheit (or around 0.9 degrees Celsius) in Earth’s mean surface warmth; this shift can be attributed predominantly to heightened levels of CO2 along with additional greenhouse gases produced through anthropogenic activities.

 Temperature Rise: A Consequence of Anthropogenic Activities
The earth's mean surface temperature has escalated approximately 1.62°F (or around 0.9°C) since the latter part of the nineteenth century—a phenomenon predominantly fueled by escalating levels of carbon dioxide along with additional anthropogenically produced discharges within the atmosphere. This alteration can be traced back to the pivotal role played by human actions in modifying the environment through extensive industrial operations and energy generation methods reliant upon fossil fuels. These alterations have significantly contributed to what scientists term "global warming," leading to observable changes across various ecosystems globally. Despite some fluctuations attributed to natural cycles, there exists overwhelming scientific consensus attributing recent trends to manmade influences—underscoring urgent need for mitigation strategies aimed at curbing greenhouse gases output while promoting sustainable development practices conducive towards preserving planetary health long-term.

The Decadent Movement was a late 19th-century artistic and literary movement , centered in Western Europe , that followed an aesthetic ideology of excess and artificiality . The visual artist Félicien Rops 's body of work and Joris-Karl Huysmans 's novel Against Nature ( 1884 ) are considered the prime examples of the decadent movement . It first flourished in France and then spread throughout Europe and to the United States . The movement was characterized by self-disgust , sickness at the world , general skepticism , delighting in perversion , and employing crude humor and a belief in the superiority of human creativity over logic and the natural world .

1969 saw humanity step onto another world for the first time . On July 21 , 1969 , the Apollo 11 Lunar Module , Eagle , landed on the moon 's surface with two astronauts aboard . Days later the crew of three returned safely to Earth , satisfying U.S. President John F. Kennedy 's 1962 challenge of May 25 , 1961 , that `` this nation should commit itself to achieving the goal , before this decade is out , of landing a man on the Moon and returning him safely to the Earth . ''   There were four Apollo missions in total in 1969 , three of which traveled to the moon , with Apollo 12 also landing on the surface . The success of the Apollo program was a testament to the efforts of over 500,000 American engineers , scientists and technicians .   In 1969 , the Soviet Union 's space program had success with the docking of two manned spacecraft as well as the success of their Venus and Lunar probes . The Soviets , however , suffered severe blows to their manned Lunar aspirations when their N1 rocket failed twice during two 1969 launches .

Large numbers are numbers that are significantly larger than those ordinarily used in everyday life , for instance in simple counting or in monetary transactions . The term typically refers to large positive integers , or more generally , large positive real numbers , but it may also be used in other contexts .   Very large numbers often occur in fields such as mathematics , cosmology , cryptography , and statistical mechanics . Sometimes people refer to numbers as being `` astronomically large '' . However , it is easy to mathematically define numbers that are much larger even than those used in astronomy .

In statistics , response surface methodology ( RSM ) explores the relationships between several explanatory variables and one or more response variables . The method was introduced by G. E. P. Box and K. B. Wilson in 1951 . The main idea of RSM is to use a sequence of designed experiments to obtain an optimal response . Box and Wilson suggest using a second-degree polynomial model to do this . They acknowledge that this model is only an approximation , but use it because such a model is easy to estimate and apply , even when little is known about the process .   Statistical approaches such as RSM can be employed to maximize the production of a special substance by optimization of operational factors . In contrast to conventional methods , the interaction among process variables can be determined by statistical techniques .

Rice is the seed of the grass species Oryza sativa ( Asian rice ) or Oryza glaberrima ( African rice ) . As a cereal grain , it is the most widely consumed staple food for a large part of the world 's human population , especially in Asia . It is the agricultural commodity with the third-highest worldwide production ( rice , 741.5 million tonnes in 2014 ) , after sugarcane ( 1.9 billion tonnes ) and maize ( 1.0 billion tonnes ) .   Since sizable portions of sugarcane and maize crops are used for purposes other than human consumption , rice is the most important grain with regard to human nutrition and caloric intake , providing more than one-fifth of the calories consumed worldwide by humans . There are many varieties of rice and culinary preferences tend to vary regionally .   Rice , a monocot , is normally grown as an annual plant , although in tropical areas it can survive as a perennial and can produce a ratoon crop for up to 30 years . Rice cultivation is well-suited to countries and regions with low labor costs and high rainfall , as it is labor-intensive to cultivate and requires ample water . However , rice can be grown practically anywhere , even on a steep hill or mountain area with the use of water-controlling terrace systems . Although its parent species are native to Asia and certain parts of Africa , centuries of trade and exportation have made it commonplace in many cultures worldwide .   The traditional method for cultivating rice is flooding the fields while , or after , setting the young seedlings . This simple method requires sound planning and servicing of the water damming and channeling , but reduces the growth of less robust weed and pest plants that have no submerged growth state , and deters vermin . While flooding is not mandatory for the cultivation of rice , all other methods of irrigation require higher effort in weed and pest control during growth periods and a different approach for fertilizing the soil .   The name wild rice is usually used for species of the genera Zizania and Porteresia , both wild and domesticated , although the term may also be used for primitive or uncultivated varieties of Oryza .

Decay heat is the heat released as a result of radioactive decay . This heat is produced as an effect of radiation on materials : the energy of the alpha , beta or gamma radiation is converted into the thermal movement of atoms .   Decay heat occurs naturally from decay of long-lived radioisotopes that are primordially present from the Earth 's formation .   In nuclear reactor engineering , decay heat plays an important role in reactor heat generation during the relatively short time after the reactor has been shut down ( see SCRAM ) , and nuclear chain reactions have been suspended . The decay of the short-lived radioisotopes created in fission continues at high power , for a time after shut down . The major source of heat production in a newly shut down reactor is due to the beta decay of new radioactive elements recently produced from fission fragments in the fission process .   Quantitatively , at the moment of reactor shutdown , decay heat from these radioactive sources is still 6.5 % of the previous core power , if the reactor has had a long and steady power history . About 1 hour after shutdown , the decay heat will be about 1.5 % of the previous core power . After a day , the decay heat falls to 0.4 % , and after a week it will be only 0.2 % . Because radioisotopes of all half life lengths are present in nuclear waste , enough decay heat continues to be produced in spent fuel rods to require them to spend a minimum of one year , and more typically 10 to 20 years , in a spent fuel pool of water , before being further processed . However , the heat produced during this time is still only a small fraction ( less than 10 % ) of the heat produced in the first week after shutdown .   If no cooling system is working to remove the decay heat from a crippled and newly shut down reactor , the decay heat may cause the core of the reactor to reach unsafe temperatures within a few hours or days , depending upon the type of core . These extreme temperatures can lead to minor fuel damage ( e.g. a few fuel particle failures ( 0.1 to 0.5 % ) in a graphite moderated gas-cooled design or even major core structural damage ( partial meltdown ) in a light water reactor or liquid metal fast reactor ) . Chemical species released from the damaged core material may lead to further explosive reactions ( steam or hydrogen ) which may further damage the reactor

Radium is a chemical element with symbol Ra and atomic number 88 . It is the sixth element in group 2 of the periodic table , also known as the alkaline earth metals . Pure radium is silvery-white , but it readily reacts with nitrogen ( rather than oxygen ) on exposure to air , forming a black surface layer of radium nitride ( Ra3N2 ) . All isotopes of radium are highly radioactive , with the most stable isotope being radium-226 , which has a half-life of 1600 years and decays into radon gas ( specifically the isotope radon-222 ) . When radium decays , ionizing radiation is a product , which can excite fluorescent chemicals and cause radioluminescence .   Radium , in the form of radium chloride , was discovered by Marie and Pierre Curie in 1898 . They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later . Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911 .   In nature , radium is found in uranium and ( to a lesser extent ) thorium ores in trace amounts as small as a seventh of a gram per ton of uraninite . Radium is not necessary for living organisms , and adverse health effects are likely when it is incorporated into biochemical processes because of its radioactivity and chemical reactivity . Currently , other than its use in nuclear medicine , radium has no commercial applications ; formerly , it was used as a radioactive source for radioluminescent devices and also in radioactive quackery for its supposed curative powers . Today , these former applications are no longer in vogue because radium 's toxicity has since become known , and less dangerous isotopes are used instead in radioluminescent devices .

The Dewey Decimal Classification ( DDC ) , or Dewey Decimal System , is a proprietary library classification system first published in the United States by Melvil Dewey in 1876 . It has been revised and expanded through 23 major editions , the latest issued in 2011 , and has grown from a four-page pamphlet in 1876 . It is also available in an abridged version suitable for smaller libraries . It is currently maintained by the Online Computer Library Center ( OCLC ) , a non-profit cooperative that serves libraries . OCLC licenses access to an online version for catalogers called WebDewey .   The Decimal Classification introduced the concepts of relative location and relative index which allow new books to be added to a library in their appropriate location based on subject . Libraries previously had given books permanent shelf locations that were related to the order of acquisition rather than topic . The classification 's notation makes use of three-digit Arabic numerals for main classes , with fractional decimals allowing expansion for further detail . Using Arabic numerals for symbols , it is flexible to the degree that numbers can be expanded in linear fashion to cover special aspects of general subjects . A library assigns a classification number that unambiguously locates a particular volume in a position relative to other books in the library , on the basis of its subject . The number makes it possible to find any book and to return it to its proper place on the library shelves.Consider as an example a book on the network protocol IPv6 . It will be located at 004.62 , after general networking books ( 004.6 ) . The shelf location is thus defined . The classification system is used in 200,000 libraries in at least 135 countries .   The major competing classification system to the Dewey Decimal system is the Library of Congress Classification system created by the U.S. Library of Congress .

Research comprises `` creative work undertaken on a systematic basis in order to increase the stock of knowledge , including knowledge of humans , culture and society , and the use of this stock of knowledge to devise new applications . '' It is used to establish or confirm facts , reaffirm the results of previous work , solve new or existing problems , support theorems , or develop new theories . A research project may also be an expansion on past work in the field . Research projects can be used to develop further knowledge on a topic , or in the example of a school research project , they can be used to further a student 's research prowess to prepare them for future jobs or reports . To test the validity of instruments , procedures , or experiments , research may replicate elements of prior projects or the project as a whole . The primary purposes of basic research ( as opposed to applied research ) are documentation , discovery , interpretation , or the research and development ( R&D ) of methods and systems for the advancement of human knowledge . Approaches to research depend on epistemologies , which vary considerably both within and between humanities and sciences . There are several forms of research : scientific , humanities , artistic , economic , social , business , marketing , practitioner research , life , technological , etc. .

The Degree Confluence Project is a World Wide Web-based , all-volunteer project which aims to have people visit each of the integer degree intersections of latitude and longitude on Earth , posting photographs and a narrative of each visit online . The project describes itself as `` an organized sampling of the world '' .
