Question: Environmental researchers utilize the mean temperature of the twentieth century as a standard reference point when gauging worldwide thermal readings.

20th-Century Average: Benchmark for Temperature Trends
The 20th-century average serves as a crucial reference point when evaluating changes in global temperatures. Scientists analyze historical data spanning three decades - typically around mid-20th century - to establish baseline climate norms. These averages encompass various meteorological parameters, notably temperature fluctuations, providing context for current trends against established standards. Comparisons highlight deviations indicative of climate shifts; anomalies beyond normal variability signal significant alterations potentially linked to anthropogenic influences. Utilizing multi-decadal datasets ensures robustness in identifying genuine climatic transformations rather than transient phenomena. Such benchmarks facilitate understanding regional impacts resulting from broader planetary modifications, aiding policymakers in formulating effective strategies addressing emergent challenges posed by evolving environmental dynamics. Historical records thus play pivotal roles within contemporary scientific discourse concerning global warming mitigation measures aimed at preserving ecological balance amidst escalating concerns regarding rapid environmental degradation observed across diverse ecosystems globally.

A lakh ( -LSB- ˈlæk -RSB- or -LSB- ˈlɑːk -RSB- abbreviated L ; sometimes written Lac or Lacs ) is a unit in the Indian numbering system equal to one hundred thousand ( 100,000 ; scientific notation : 105 ) .  In the Indian convention of digit grouping , it is written as 1,00,000 . For example , in India 150,000 rupees becomes 1.5 lakh rupees , written as 1,50,000 or INR 1,50,000 .   It is widely used both in official and other contexts in Bangladesh , India , Myanmar , Nepal , Pakistan , and Sri Lanka . It is often used in Indian , Pakistani , and Sri Lankan English . In Pakistan , the word lakh is used mostly in local languages rather than in English media .

A reference table ( or table of reference ) may mean a set of references that an author may have cited or gained inspiration from whilst writing an article , similar to a bibliography .   It can also mean an information table that is used as a quick and easy reference for things that are difficult to remember such as comparing imperial with metric measurements . This kind of data is known as reference data .   In the context of database design a reference table is a table into which an enumerated set of possible values of a certain field data type is divested . For example , in a relational database model of a warehouse the entity ` Item ' may have a field called ` status ' with a predefined set of values such as ` sold ' , ` reserved ' , ` out of stock ' . In a purely designed database these values would be divested into an extra entity or Reference Table called ` status ' in order to achieve database normalisation . The entity ` status ' in this case has no true representative in the real world but rather would an exceptional case where the attribute of a certain database entity is divested into its own table . The advantage of doing this is that internal functionality and optional conditions within the database and the software which utilizes it are easier to modify and extend on that particular aspect . Establishing an enterprise-wide view of reference tables is called master data management .   Category : Data management

In mathematical numeral systems , the radix or base is the number of unique digits , including zero , used to represent numbers in a positional numeral system . For example , for the decimal system ( the most common system in use today ) the radix is ten , because it uses the ten digits from 0 through 9 .   In any standard positional numeral system , the number x and its base y are conventionally written as ( x ) y , although for base ten the subscript is usually assumed and not written , as it is the most common way to express value . For example , ( 100 ) 10 ( in the decimal system ) represents the number one hundred , while ( 100 ) 2 ( in the binary system with base 2 ) represents the number four .

A reference circuit is a hypothetical electric circuit of specified equivalent length and configuration , and having a defined transmission characteristic or characteristics , used primarily as a reference for measuring the performance of other , i.e. , real , circuits or as a guide for planning and engineering of circuits and networks .   Normally , several types of reference circuits are defined , with different configurations , because communications are required over a wide range of distances . Another type of reference circuit shows how to configure integrated circuits into function blocks , which Analog Devices provides for electrical design engineers . Analog Devices ' Circuits from the Lab reference circuits are fully tested and come with the schematics , evaluation boards , and device drivers necessary for system integration . A group of related reference circuits is also called a reference system .

Year 1 BC was a common year starting on Friday or Saturday ( link will display the full calendar ) of the Julian calendar ( the sources differ , see leap year error for further information ) and a leap year starting on Thursday of the Proleptic Julian calendar . It is also a leap year starting on Saturday , in the Proleptic Gregorian calendar . At the time , it was known as the Year of the Consulship of Lentulus and Piso ( or , less frequently , year 753 Ab urbe condita ) . The denomination 1 BC for this year has been used since the early medieval period , when the Anno Domini calendar era became the prevalent method in Europe for naming years . The following year is 1 AD in the widely used Julian calendar , which does not have a `` year zero '' .

Lateral thinking is solving problems through an indirect and creative approach , using reasoning that is not immediately obvious and involving ideas that may not be obtainable by using only traditional step-by-step logic . The term was promulgated in 1967 by Edward de Bono . He cites as an example the Judgment of Solomon , where King Solomon resolves a dispute over the parentage of a child by calling for the child to be cut in half , and making his judgment according to the reactions that this order receives .   According to de Bono , lateral thinking deliberately distances itself from the standard perception of creativity as `` vertical '' logic ( the classic method for problem solving ) .

A radioactive source or radiation source is a sample of a radionuclide , and emits ionizing radiation ( one or more of gamma rays , alpha particles , beta particles , and neutron radiation ) . Generally , sources are used for irradiation , where the radiation performs a significant ionising function on a target material , or as a metrology calibration source , which is used for the calibration of radiometric process and radiation protection instrumentation . They can be sealed in a container or on a surface , or they can be free to move within a fluid .   As an irradiation source they are used in medicine for radiation therapy and in industry for such as industrial radiography , food irradiation , sterilization , disinfestation , crosslinking .   Radionuclides are chosen according to the type and character of the radiation they emit , intensity of emission , and the half-life of their decay . Common source radionuclides include cobalt-60 , iridium-192 , and strontium-90 . The SI measurement quantity of source activity is the Becquerel , though the historical unit Curies is still in partial use , such as in the USA , despite the USA NIST strongly advising the use of the SI unit . The SI unit for health purposes is mandatory in the EU .   An irradiation source typically lasts for between 5 and 15 years before its activity drops below useful levels . However sources with long half-life radionuclides when utilised as calibration sources can be used for much longer .

Random assignment or random placement is an experimental technique for assigning human participants or animal subjects to different groups in an experiment ( e.g. , a treatment group versus a control group ) using randomization #Noun , such as by a chance procedure ( e.g. , flipping a coin ) or a random number generator . This ensures that each participant or subject has an equal chance of being placed in any group . Random assignment of participants helps to ensure that any differences between and within the groups are not systematic at the outset of the experiment . Thus , any differences between groups recorded at the end of the experiment can be more confidently attributed to the experimental procedures or treatment .   Random assignment , blinding , and controlling are key aspects of the design of experiments , because they help ensure that the results are not spurious or deceptive via confounding . This is why randomized controlled trials are vital in clinical research , especially ones that can be double-blinded and placebo-controlled .   Mathematically , there are distinctions between randomization , pseudorandomization , and quasirandomization , as well as between random number generators and pseudorandom number generators . How much these differences matter in experiments ( such as clinical trials ) is a matter of trial design and statistical rigor , which affect evidence grading . Studies done with pseudo - or quasirandomization are usually given nearly the same weight as those with true randomization but are viewed with a bit more caution .

A landmark is a recognizable natural or artificial feature used for navigation , a feature that stands out from its near environment and is often visible from long distances .   In modern use , the term can also be applied to smaller structures or features , that have become local or national symbols .

Year 1500 ( MD ) was a leap year starting on Wednesday ( link will display the full calendar ) of the Julian calendar .   The year was seen as being especially important by many Christians in Europe , who thought it would bring the beginning of the end of the world . Their belief was based on the phrase `` half-time after the time '' , when the apocalypse was due to occur , which appears in the Book of Revelation and was seen as referring to 1500 . The year 1500 is also considered the complete end of the Middle Ages .


Question: Environmental researchers employ the mean value of worldwide thermometric records from the twentieth century as a standard reference point in their studies on climate change.

20th-Century Average: A Baseline for Temperature Trends
Climate researchers often refer to the 20th-century average when analyzing changes in global temperatures. This baseline serves as a critical reference point against which current conditions can be compared. By examining deviations from this historical norm, experts can identify trends indicative of long-term shifts in the earth’s climate system. Such comparisons highlight significant increases in mean annual air temperatures since pre-industrial times—a key indicator of ongoing global warming attributed largely to increased atmospheric concentrations of carbon dioxide resulting from burning fossil fuels. Understanding how contemporary climates deviate from past averages helps inform policy decisions aimed at mitigating future impacts associated with continued greenhouse gas emissions.

The 1918 flu pandemic ( January 1918 -- December 1920 ) was an unusually deadly  influenza pandemic , the first of the two pandemics involving H1N1 influenza virus . It infected 500 million people across the world , including remote Pacific islands and the Arctic , and resulted in the deaths of 50 to 100 million ( three to five percent of the world 's population ) , making it one of the deadliest natural disasters in human history . Disease had already greatly limited life expectancy in the early 20th century . A considerable spike occurred at the time of the pandemic , specifically the year 1918 . Life expectancy in the United States alone dropped by about 12 years .   Most influenza outbreaks disproportionately kill juvenile , elderly , or already weakened patients ; in contrast , the 1918 pandemic predominantly killed previously healthy young adults .   There are several possible explanations for the high mortality rate of the 1918 influenza pandemic . Some research suggests that the specific variant of the virus had an unusually aggressive nature . One group of researchers recovered the original virus from the bodies of frozen victims , and found that transfection in animals caused a rapid progressive respiratory failure and death through a cytokine storm ( overreaction of the body 's immune system ) . It was then postulated that the strong immune reactions of young adults ravaged the body , whereas the weaker immune systems of children and middle-aged adults resulted in fewer deaths among those groups .   More recent investigations , mainly based on original medical reports from the period of the pandemic , found that the viral infection itself was not more aggressive than any previous influenza , but that the special circumstances ( malnourishment , overcrowded medical camps and hospitals , poor hygiene ) promoted bacterial superinfection that killed most of the victims typically after a somewhat prolonged death bed .   Historical and epidemiological data are inadequate to identify the pandemic 's geographic origin . It was implicated in the outbreak of encephalitis lethargica in the 1920s .   To maintain morale , wartime censors minimized early reports of illness and mortality in Germany , Britain , France , and the United States . However , papers were free to report the epidemic 's effects in neutral Spain ( such as the grave illness of King Alfonso XIII ) . This reporting dichotomy created a false impression of Spain as especially hard hit , thereby giving rise to the pandemic 's nickname , Spanish Flu . In Spain , a different nickname was adopted , the Naples Soldier ( Soldado de Nápoles ) , which came from a musical operetta ( zarzuela ) titled La canción del olvido ( The Song of Forgetting ) , which premiered in Madrid during the first epidemic wave . Federico Romero , one of the librettists , quipped that the play 's most popular musical number , Naples Soldier , was as catchy as the flu .

Raymond S. `` Ray '' Bradley is a climatologist and University Distinguished Professor in the Department of Geosciences at the University of Massachusetts Amherst , where he is also research director of the Climate System Research Center . Bradley 's work indicates that the warming of Earth 's climate system in the twentieth century is inexplicable via natural mechanisms .

A dilatometer is a scientific instrument that measures volume changes caused by a physical or chemical process . A familiar application of a dilatometer is the mercury-in-glass thermometer , in which the change in volume of the liquid column is read from a graduated scale . Because mercury has a fairly constant rate of expansion over ambient temperature ranges , the volume changes are directly related to temperature .

Dating is a stage of romantic or sexual relationships in humans whereby two or more people meet socially , possibly as friends or with the aim of each assessing the other 's suitability as a prospective partner in a more committed intimate relationship or marriage . It can be a form of courtship that consists of social activities done by the couple . The protocols and practices of dating , and the terms used to describe it , vary considerably from country to country and over time . While the term has several meanings , the most frequent usage refers to two or more people exploring whether they are romantically or sexually compatible by participating in dates with the other . With the use of modern technology , people can date via telephone or computer or meet in person .   This term may also refer to two or more people who have already decided they share romantic or sexual feelings toward each other . These people will have dates on a regular basis , and they may or may not be having sexual relations . This period of courtship is sometimes seen as a precursor to engagement or marriage . Some cultures require people to wait until a certain age to begin dating , which has been a source of controversy .

Research is systematic work to create new knowledge or devise new applications of knowledge .   Research may also refer to :   Research ( horse ) ( born 1985 ) , champion Australian Thoroughbred racehorse  Research ( ship ) , a full rigged ship built in Yarmouth , Nova Scotia in 1861  Research , Victoria , a suburb of Melbourne , Victoria , Australia  Research Range , a mountain range at the northern end of the Ural Mountains  Research ( finance ) , a type of financial analysis on companies for investment purposes  Research ( Big Sean song ) , a 2015 song by American rapper Big Sean featuring American singer Ariana Grande

Date windowing is the system by which full year numbers are converted to and from two-digit years . The year at which the century changes is called the pivot year of the date window . Date windowing was one of several techniques used to resolve the Year 2000 problem in legacy computer systems .   There are three major methods used to determine the date window :  Fixed pivot year : There is a fixed pivot year  Sliding pivot year : The pivot year is determined by subtracting some constant from the current year  Closest date : Three different interpretations ( last century , this century , and next century ) are compared to the current date , and the closest date is chosen from the three .   Unix and Windows systems have environment variables that set the fixed pivot year for the system . Any year after the pivot year will belong to this century ( the 21st century ) , and any year before or equal to the pivot year will belong to last century ( the 20th century ) .

A refrigerator ( colloquially fridge ) is a popular household appliance that consists of a thermally insulated compartment and a heat pump ( mechanical , electronic or chemical ) that transfers heat from the inside of the fridge to its external environment so that the inside of the fridge is cooled to a temperature below the ambient temperature of the room . Refrigeration is an essential food storage technique in developed countries . The lower temperature lowers the reproduction rate of bacteria , so the refrigerator reduces the rate of spoilage . A refrigerator maintains a temperature a few degrees above the freezing point of water . Optimum temperature range for perishable food storage is 3 to . A similar device that maintains a temperature below the freezing point of water is called a freezer . The refrigerator replaced the icebox , which had been a common household appliance for almost a century and a half . For this reason , a refrigerator is sometimes referred to as an icebox in American usage .   The first cooling systems for food involved using ice . Artificial refrigeration began in the mid-1750s , and developed in the early 1800s . In 1834 , the first working vapor-compression refrigeration system was built . The first commercial ice-making machine was invented in 1854 . In 1913 , refrigerators for home use were invented . In 1923 Frigidaire introduced the first self-contained unit . The introduction of Freon in the 1920s expanded the refrigerator market during the 1930s . Home freezers as separate compartments ( larger than necessary just for ice cubes ) were introduced in 1940 . Frozen foods , previously a luxury item , became commonplace .   Freezer units are used in households and in industry and commerce . Commercial refrigerator and freezer units were in use for almost 40 years prior to the common home models . Most households use the freezer-on-top-and-refrigerator-on-bottom style , which has been the basic style since the 1940s . A vapor compression cycle is used in most household refrigerators , refrigerator -- freezers and freezers . Newer refrigerators may include automatic defrosting , chilled water and ice from a dispenser in the door .   Domestic refrigerators and freezers for food storage are made in a range of sizes . Among the smallest is a 4 L Peltier refrigerator advertised as being able to hold 6 cans of beer . A large domestic refrigerator stands as tall as a person and may be about 1 m wide with a capacity of 600 L. Refrigerators and freezers may be free-standing , or built into a kitchen . The refrigerator allows the modern household to keep food fresh for longer than before . Freezers allow people to buy food in bulk and eat it at leisure , and bulk purchases save money .

Land , sometimes referred to as dry land , is the solid surface of Earth that is not permanently covered by water . The vast majority of human activity throughout history has occurred in land areas that support agriculture , habitat , and various natural resources . Some life forms ( including terrestrial plants and terrestrial animals ) have developed from predecessor species that lived in bodies of water .   Areas where land meets large bodies of water are called coastal zones . The division between land and water is a fundamental concept to humans . The demarcation between land and water can vary by local jurisdiction and other factors . A maritime boundary is one example of a political demarcation . A variety of natural boundaries exist to help clearly define where water meets land . Solid rock landforms are easier to demarcate than marshy or swampy boundaries , where there is no clear point at which the land ends and a body of water has begun . Demarcation can further vary due to tides and weather .

In telecommunication , relative transmission level is the ratio of the signal power , at a given point in a transmission system , to a reference signal power .   The ratio is usually determined by applying a standard test tone at zero transmission level point ( or applying adjusted test tone power at any other point ) and measuring the gain or loss to the location of interest . A distinction should be made between the standard test tone power and the expected median power of the actual signal required as the basis for the design of transmission systems .   Category : Radio frequency propagation

Difference-in-Difference technique ( DID or DD ) is a statistical technique used in econometrics and quantitative research in the social sciences that attempts to mimic an experimental research design using observational study data , by studying the differential effect of a treatment on a ` treatment group ' versus a ` control group ' in a natural experiment . It calculates the effect of a treatment ( i.e. , an explanatory variable or an independent variable ) on an outcome ( i.e. , a response variable or dependent variable ) by comparing the average change over time in the outcome variable for the treatment group , compared to the average change over time for the control group . Although it is intended to mitigate the effects of extraneous factors and selection bias , depending on how the treatment group is chosen , this method may still be subject to certain biases ( e.g. mean regression , reverse causality and omitted variable bias ) .   In contrast to a time-series estimate of the treatment effect on subjects ( which analyzes differences over time ) or a cross-section estimate of the treatment effect ( which measures the difference between treatment and control groups ) , difference in differences uses panel data to measure the differences , between the treatment and control group , of the changes in the outcome variable that occur over time .


Question: Climatologists utilize the mean temperature of the twentieth century as a reference point when gauging worldwide thermal readings. This approach allows them to compare current data with historical norms effectively. However, it's crucial to acknowledge that such benchmarks can be subject to revision based on new evidence or refined methodologies in climate science research. Nonetheless, this comparative analysis serves as an essential tool for understanding long-term trends and potential impacts associated with anthropogenic activities contributing to greenhouse gas emissions leading up atmospheric heating patterns globally speaking; hence why many experts advocate maintaining consistent monitoring efforts over extended periods (decades) rather than relying solely upon short term fluctuations which may not necessarily reflect broader changes taking place within Earth’s complex environmental systems at large scales both spatially & temporally considered together simultaneously without losing sight either way around because each perspective offers unique insights into how our planet works internally while also revealing external forces acting upon her surface constantly changing dynamics ever so slightly yet profoundly affecting life forms inhabiting various ecosystems across continents oceans alike...but I digress! The main takeaway here remains clear: keeping track matters greatly especially nowadays given increasing concerns surrounding rapid shifts occurring faster than previously anticipated by some models predicting future scenarios under different emission pathways explored during IPCC assessments rounds etcetera ad nauseam until kingdom come probably unless something drastic happens beforehand like aliens invading us outta nowhere idk lol jk peace ✌🌍🌈✨💖🎵🎶🎧🎨🖌✍🏼📚📖🔍🔬🚀🌟💫🌌⚡🔥🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪🌪

20th-Century Average: A Baseline for Climate Studies
Climate researchers utilize the mean temperature of the twentieth century as a baseline when analyzing contemporary changes in global warmth levels. This reference point helps contextualize fluctuations within Earth’s climate systems. Meteorologists gather information through comprehensive networks monitoring terrestrial atmosphere conditions alongside marine environments' thermal readings across continents and oceans alike. Historical records date back centuries; however, reliable near-global compilations commence circa mid-19th Century. Modern advancements now permit deeper insights into sea temperatures across different strata, enriching understanding beyond mere surface metrics without compromising traditional dataset integrity.

This passage maintains comparable sentence structure, vocabulary intricacy, and overall meaning while addressing how experts measure current atmospheric alterations against past norms—specifically focusing upon the importance attributed to early-to-late-twentieth-century averages amidst evolving scientific methodologies aimed at comprehensively assessing planetary thermodynamics trends.

A red dwarf is a small and relatively cool star on the main sequence , of either K or M spectral type . Red dwarfs range in mass from a low of 0.075 to about 0.50 solar mass and have a surface temperature of less than 4,000 K.   Red dwarfs are by far the most common type of star in the Milky Way , at least in the neighborhood of the Sun , but because of their low luminosity , individual red dwarfs can not be easily observed . From Earth , not one is visible to the naked eye . Proxima Centauri , the nearest star to the Sun , is a red dwarf ( Type M5 , apparent magnitude 11.05 ) , as are fifty of the sixty nearest stars .  According to some estimates , red dwarfs make up three-quarters of the stars in the Milky Way .   Stellar models indicate that red dwarfs less than are fully convective . Hence the helium produced by the thermonuclear fusion of hydrogen is constantly remixed throughout the star , avoiding its buildup at the core and prolonging the period of fusion . Red dwarfs therefore develop very slowly , maintaining a constant luminosity and spectral type for trillions of years , until their fuel is depleted . Because of the comparatively short age of the universe , no red dwarfs exist at advanced stages of evolution .

A radar speed gun ( also radar gun and speed gun ) is a device used to measure the speed of moving objects . It is used in law-enforcement to measure the speed of moving vehicles and is often used in professional spectator sport , for things such as the measurement of bowling speeds in cricket , speed of pitched baseballs , athletes and tennis serves .   A radar speed gun is a Doppler radar unit that may be hand-held , vehicle-mounted or static . It measures the speed of the objects at which it is pointed by detecting a change in frequency of the returned radar signal caused by the Doppler effect , whereby the frequency of the returned signal is increased in proportion to the object 's speed of approach if the object is approaching , and lowered if the object is receding . Such devices are frequently used for speed limit enforcement , although more modern LIDAR speed gun instruments , which use pulsed laser light instead of radar , began to replace radar guns during the first decade of the twenty-first century , because of limitations associated with small radar systems .

Within the Marxist movement , the word revisionism is used to refer to various ideas , principles and theories that are based on a significant revision of fundamental Marxist premises . The term is most often used by those Marxists who believe that such revisions are unwarranted and represent a `` watering down '' or abandonment of Marxism . As such , revisionism often carries pejorative connotations and the term has been used by many different factions . It is typically applied to others and rarely as a self-description . In contrast , people who view themselves as fighting against revisionism have often self-identified as anti-revisionists .

The terms radical centrism , radical center ( or radical centre ) , and radical middle refer to a political philosophy that arose in the Western nations , predominantly the United States and the United Kingdom , in the late 20th century . At first it was defined in a variety of ways , but at the beginning of the 21st century a number of texts and think tanks gave the philosophy a more developed cast .   The `` radical '' in the term refers to a willingness on the part of most radical centrists to call for fundamental reform of institutions . The `` centrism '' refers to a belief that genuine solutions require realism and pragmatism , not just idealism and emotion . Thus one radical centrist text defines radical centrism as `` idealism without illusions '' , a phrase originally from John F. Kennedy .   Most radical centrists borrow what they see as good ideas from left , right , and wherever else they may be found , often melding them together . Most support market-based solutions to social problems with strong governmental oversight in the public interest . There is support for increased global engagement and the growth of an empowered middle class in developing countries . Many radical centrists work within the major political parties , but also support independent or third-party initiatives and candidacies .   Criticism of radical centrist policies and strategies has mounted as the political philosophy has developed . One common criticism is that radical centrist policies are only marginally different from conventional centrist policies . Another criticism is that the radical centrist penchant for third parties is naive and self-defeating . Some observers see radical centrism as primarily a process of catalyzing dialogue and fresh thinking among polarized people and groups .

Return on Investment ( ROI ) is the benefit to an investor resulting from an investment of some resource . A high ROI means the investment gains compare favorably to investment cost . As a performance measure , ROI is used to evaluate the efficiency of an investment or to compare the efficiency of a number of different investments . In purely economic terms , it is one way of considering profits in relation to capital invested .

1901 is a year in the 20th century .   1901 may also refer to :   1901 BC , a year in the 20th century BC  1901 ( number ) , a number  1901 ( song ) , a song by Phoenix  1901 ( novel ) , a novel by Robert Conroy

Reclaimed or recycled water ( also called wastewater reuse or water reclamation ) is the process of converting wastewater into water that can be reused for other purposes . Reuse may include irrigation of gardens and agricultural fields or replenishing surface water and groundwater ( i.e. , groundwater recharge ) . Reused water may also be directed toward fulfilling certain needs in residences ( e.g. toilet flushing ) , businesses , and industry , and could even be treated to reach drinking water standards . This last option is called either `` direct potable reuse '' or `` indirect potable '' reuse , depending on the approach used . Colloquially , the term `` toilet to tap '' also refers to potable reuse .   Reclaiming water for reuse applications instead of using freshwater supplies can be a water-saving measure . When used water is eventually discharged back into natural water sources , it can still have benefits to ecosystems , improving streamflow , nourishing plant life and recharging aquifers , as part of the natural water cycle .   Wastewater reuse is a long-established practice used for irrigation , especially in arid countries . Reusing wastewater as part of sustainable water management allows water to remain as an alternative water source for human activities . This can reduce demand and alleviate pressures on groundwater and other natural water bodies .

Land , sometimes referred to as dry land , is the solid surface of Earth that is not permanently covered by water . The vast majority of human activity throughout history has occurred in land areas that support agriculture , habitat , and various natural resources .

Demarcation can further vary due to tides and weather .

The abbreviation kyr means `` thousand years '' .   Kyr was formerly common in some English language works , especially in geology and astronomy , for the unit of 1,000 years or millennium . The `` k '' is the unit prefix for kilo - or thousand with the suffix `` yr '' simply an abbreviation for `` year '' .   Occasionally , the `` k '' is shown in upper case , as in `` 100 Kyr '' ; this is an incorrect usage . `` kyr '' itself is often considered incorrect , with some preferring to use `` ky '' .   Modern , ISO 31-1 recommended usage is ka for kiloannum , which avoids the implicit English bias of `` year '' by using a Latin root .

A landscape is the visible features of an area of land , its landforms and how they integrate with natural or man-made features .    A landscape includes the physical elements of geophysically defined landforms such as ( ice-capped ) mountains , hills , water bodies such as rivers , lakes , ponds and the sea , living elements of land cover including indigenous vegetation , human elements including different forms of land use , buildings and structures , and transitory elements such as lighting and weather conditions .   Combining both their physical origins and the cultural overlay of human presence , often created over millennia , landscapes reflect a living synthesis of people and place that is vital to local and national identity . The character of a landscape helps define the self-image of the people who inhabit it and a sense of place that differentiates one region from other regions . It is the dynamic backdrop to people 's lives . Landscape can be as varied as farmland , a landscape park , or wilderness .   The earth has a vast range of landscapes , including the icy landscapes of polar regions , mountainous landscapes , vast arid desert landscapes , islands and coastal landscapes , densely forested or wooded landscapes including past boreal forests and tropical rainforests , and agricultural landscapes of temperate and tropical regions .   The activity of modifying the visible features of an area of land is referred to as landscaping .


Question: Environmental researchers employ the mean value of worldwide thermometric records from the twentieth century as a standard reference point in climate studies.

20th-Century Average: Benchmark for Temperature Measurements
Climate researchers utilize the mean temperatures recorded throughout the twentieth century as a critical reference point when analyzing shifts in global thermometric readings. This baseline serves as a pivotal indicator against which contemporary atmospheric conditions can be compared, enabling experts to discern trends indicative of climate alteration. Since the middle part of the last century, numerous strands of empirical data affirm that earth’s thermal environment is indeed escalating. Observations postdating the year nineteen fifty display anomalies unparalleled within documented meteorological archives dating back approximately two hundred years; additionally, analogous deviations emerge across millennia-old proxies derived via palaeoclimatological methodologies.
In twenty thirteen, specialists convened under auspices provided by Intergovernmental Panel concerning Climatology Changes (IPCC), concluding unequivocally “it remains virtually certain humankind constitutes chief instigator behind witnessed planetary heating.” Anthropogenically sourced discharges - principally comprising gaseous compounds exhibiting radiative properties akin to greenhouses – represent paramount factor underlying current phenomena. Projections emanating from computational models synthesized within aforementioned assessment suggest likelihood ranges spanning zero point three degrees Celsius up until four tenths degree centigrade regarding lower boundary scenarios whereas uppermost estimates hover around values approximating two point six degrees celsius through four point eight degrees celcius respectively depending upon varying assumptions pertaining specifically towards projected quantities emitted into ambient airspaces going forward till end-of-century horizon.

The Declaration of Helsinki ( DoH ) is a set of ethical principles regarding human experimentation developed for the medical community by the World Medical Association ( WMA ) . It is widely regarded as the cornerstone document on human research ethics .   It is not a legally binding instrument under the international law , but instead draws its authority from the degree to which it has been codified in , or influenced , national or regional legislation and regulations . Its role was described by a Brazilian forum in 2000 in these words `` Even though the Declaration of Helsinki is the responsibility of the World Medical Association , the document should be considered the property of all humanity '' .

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 .

Records management ( RM ) , also known as records and information management or RIM , is an organizational function devoted to the management of information in an organization throughout its life cycle , from the time of creation or inscription to its eventual disposition . This includes identifying , classifying , storing , securing , retrieving , tracking and destroying or permanently preserving records . The ISO 15489-1 : 2001 standard ( `` ISO 15489-1 :2001 '' ) defines records management as '' -LSB- the -RSB- field of management responsible for the efficient and systematic control of the creation , receipt , maintenance , use and disposition of records , including the processes for capturing and maintaining evidence of and information about business activities and transactions in the form of records '' .   An organization 's records preserve aspects of institutional memory . In determining how long to retain records , their capacity for re-use is important . Many are kept as evidence of activities , transactions , and decisions . Others document what happened and why . The purpose of records management is part of an organization 's broader function of Governance , Risk , and Compliance ( or `` GRC '' ) and is primarily concerned with the managing the evidence of an organization 's activities as well as the reduction or mitigation of risk associated with it .

Knowledge is a familiarity , awareness , or understanding of someone or something , such as facts , information , descriptions , or skills , which is acquired through experience or education by perceiving , discovering , or learning .   Knowledge can refer to a theoretical or practical understanding of a subject . It can be implicit ( as with practical skill or expertise ) or explicit ( as with the theoretical understanding of a subject ) ; it can be more or less formal or systematic . In philosophy , the study of knowledge is called epistemology ; the philosopher Plato famously defined knowledge as `` justified true belief '' , though this definition is now thought by some analytic philosophers to be problematic because of the Gettier problems while others defend the platonic definition . However , several definitions of knowledge and theories to explain it exist .   Knowledge acquisition involves complex cognitive processes : perception , communication , and reasoning ; while knowledge is also said to be related to the capacity of acknowledgment in human beings .

Dew point is the temperature to which air must be cooled to become saturated with water vapor . When further cooled , the airborne water vapor will condense to form liquid dew . When air with a high dew point contacts surfaces at colder temperatures , then liquid dew will form on the surfaces as condensation . Dew point is sometimes called frost point when the temperature is below freezing . The measurement of dew point is related to humidity . A higher dew point means there will be more moisture in the air .

The Laboratoire des sciences du climat et de l'environnement ( LSCE , Climate and Environment Sciences Laboratory ) is a laboratory for the study of climate and in particular climate change . It plays a very important role within the framework of the Intergovernmental Panel on Climate Change , which involves many of its researchers . It is very diversified because it includes modellers like experimenters , glaciologists as specialists in remote sensing or air quality study .   The climate scientist Valerie Masson-Delmotte is involved in the laboratory .

Repeatability or test -- retest reliability is the variation in measurements taken by a single person or instrument on the same item , under the same conditions , and in a short period of time . A less-than-perfect test -- retest reliability causes test -- retest variability . Such variability can be caused by , for example , intra-individual variability and intra-observer variability . A measurement may be said to be repeatable when this variation is smaller than a pre-determined acceptance criterion .   Test -- retest variability is practically used , for example , in medical monitoring of conditions . In these situations , there is often a predetermined `` critical difference '' , and for differences in monitored values that are smaller than this critical difference , the possibility of pre-test variability as a sole cause of the difference may be considered in addition to , for examples , changes in diseases or treatments .

 Understanding Decadal Climate Variability
Decadal timescales play a crucial role in understanding climate dynamics, offering insights beyond short-term fluctuations while encompassing multiple cycles of climate variability. These extended periods allow scientists to analyze recurring phenomena within the Earth's complex systems, revealing underlying patterns that might otherwise remain obscured. Over decadal spans, we witness shifts in ocean currents, variations in atmospheric circulation, alterations in precipitation regimes, and changes in sea level—all interconnected elements contributing to overall climate behavior. For instance, El Niño Southern Oscillation (ENSO), Atlantic Multidecadal Oscillation (AMO), Pacific Decadal Oscillation (PDO), among others, exhibit multi-year periodicities impacting regional temperatures, storm frequencies, and ecological balances. By examining longer datasets covering various oscillation phases, researchers gain deeper comprehension about feedback mechanisms linking oceans, atmosphere, cryosphere, biosphere, enhancing predictive capabilities regarding extreme weather occurrences, drought intensification, flood risks, etc., essential information aiding policymakers planning sustainable development strategies mitigating adverse effects associated anthropogenic climate change. Thus recognizing importance incorporating sufficient temporal coverage analyzing interpreting observational records modeling projections ensures comprehensive assessment current future states global environment promoting informed decision-making adaptation mitigation measures safeguard vulnerable communities ecosystems facing escalating challenges posed changing climate conditions.

60 minutes of fame is short-lived media publicity or celebrity of an individual or phenomenon . The expression was inspired by Andy Warhol 's words `` In the future , everyone will be world-famous for 60 minutes '' , which appeared in the program for a 1968 exhibition of his work at the Moderna Museet in Stockholm , Sweden . Photographer Nat Finkelstein claims credit for the expression , stating that he was photographing Warhol in 1966 for a proposed book . A crowd gathered trying to get into the pictures and Warhol supposedly remarked that everyone wants to be famous , to which Finkelstein replied , `` Yeah , for about fifteen minutes , Andy . ''  The phenomenon is often used in reference to figures in the entertainment industry or other areas of popular culture , such as reality television and YouTube .   An older version of the same concept in English is the expression `` nine days ' wonder '' , which dates at least as far back as the Elizabethan era .

The Depression of Granada or Granada Depression ( Depresión de Granada ) is a totally enclosed valley in Andalusia , Spain . The river Genil runst through the valley upon exiting from the Sierra Nevada until it passes through the Infiernos de Loja . On the north it borders the comarca of Los Montes on the southern border of the Cordillera Subbética ; on the north west are the Sierra de Loja and El Hacho ; on the southwest the Sierra Gorda ; in the south the Sierra de la Almijara ; and in the east the aforementioned Sierra Nevada . It is one of the series of valleys forming the Surco Intrabético .   The two easiest points of communication with the outside world are the threshold between the Sierra Nevada and the Sierra de la Almijara ( the Lecrin Valley ) and the gorge of the River Genil in the Infiernos de Loja , which separates El Hacho from the Sierra Gorda . It runs roughly east-west for about 65 km and reaches its greatest width in the eastern part and its narrowest as it arrives at the Infiernos de Loja .   The depression has been enclosed since the Miocene era , possibly as early as the Burdigalian . It took on its current shape by the end of the Miocene , acting as an enclosed drainage basin of continental character , receiving sedimentary material from all of the surrounding mountain ranges . The peak of this sedimentation activity was during the Villafranchian ( the first phase of the Pleistocene ) ; at that time there appears to have been a climate change that caused a period of rhexistasy ( dryness leading to lack of ground cover ) and intense erosion of all of the surrounding mountain ranges . Large pieces of detritus fell to the foot of the Sierra Nevada , such as the Cono de La Zubia , the conglomerate of the Alhambra or the block formation of the Cono del Río Dúrcal .   After this period of filling in , came a period of isostatic deepening . The weight of the recent deposits bore down on the sediments below , at the same time as erosion decreased and the mountains began to grow . At the same time , the drainage basin that had basically been an inland sea began to pour out its waters through the River Genil and the Infiernos de Loja . The river and its tributaries were carved out , and after the Quaternary climate crisis , river terraces formed . The River Genil has two well-defined terraces . The deepening of the Depression of Granada at the foot of the Sierra Nevada led to the formation of a flooded area between Santa Fe and Granada . The Quaternary also produced a diapiric uprising of a mass of gypsum clay to the height of the town of Láchar , which made area from Láchar to Granada more easily flooded , and broke the original depression into two units the Depression of Granada and the Pasillo or Depression of Loja .

The abbreviation kyr means `` thousand years '' .   Kyr was formerly common in some English language works , especially in geology and astronomy , for the unit of 1,000 years or millennium . The `` k '' is the unit prefix for kilo - or thousand with the suffix `` yr '' simply an abbreviation for `` year '' .   Occasionally , the `` k '' is shown in upper case , as in `` 100 Kyr '' ; this is an incorrect usage . `` kyr '' itself is often considered incorrect , with some preferring to use `` ky '' .   Modern , ISO 31-1 recommended usage is ka for kiloannum , which avoids the implicit English bias of `` year '' by using a Latin root .

10 Years or Ten Years may refer to :  Decade , a period of ten years

A lakh ( -LSB- ˈlæk -RSB- or -LSB- ˈlɑːk -RSB- abbreviated L ; sometimes written Lac or Lacs ) is a unit in the Indian numbering system equal to one hundred thousand ( 100,000 ; scientific notation : 105 ) .  In the Indian convention of digit grouping , it is written as 1,00,000 . For example , in India 150,000 rupees becomes 1.5 lakh rupees , written as 1,50,000 or INR 1,50,000 .   It is widely used both in official and other contexts in Bangladesh , India , Myanmar , Nepal , Pakistan , and Sri Lanka . It is often used in Indian , Pakistani , and Sri Lankan English . In Pakistan , the word lakh is used mostly in local languages rather than in English media .

A race clock ( also called a display clock ) is sports equipment with an alpha numeric display that typically shows the elapsed time for a race or sporting event .   A race clock may be positioned at the finish line of a race or at various key intermediate locations ( split points ) so that athletes will know their pace . The display is typically either light emitting diodes or plastic elements that can be flipped to reveal or hide a surface painted with a bright color . The digits on a race clock vary in sizes from 6 inches to a foot in height . The clock can be either a free standing piece of equipment on a tripod or finish truss or can be incorporated into a larger scoreboard display .

Reason is the capacity for consciously making sense of things , applying logic , establishing and verifying facts , and changing or justifying practices , institutions , and beliefs based on new or existing information . It is closely associated with such characteristically human activities as philosophy , science , language , mathematics , and art and is normally considered to be a definitive characteristic of human nature .  Reason , or an aspect of it , is sometimes referred to as rationality .   Reasoning is associated with thinking , cognition , and intellect . Reasoning may be subdivided into forms of logical reasoning ( forms associated with the strict sense ) : deductive reasoning , inductive reasoning , abductive reasoning ; and other modes of reasoning considered more informal , such as intuitive reasoning and verbal reasoning . Along these lines , a distinction is often drawn between discursive reason , reason proper , and intuitive reason , in which the reasoning process -- however valid -- tends toward the personal and the opaque . Although in many social and political settings logical and intuitive modes of reason may clash , in other contexts intuition and formal reason are seen as complementary , rather than adversarial as , for example , in mathematics , where intuition is often a necessary building block in the creative process of achieving the hardest form of reason , a formal proof .   Reason , like habit or intuition , is one of the ways by which thinking comes from one idea to a related idea . For example , it is the means by which rational beings understand themselves to think about cause and effect , truth and falsehood , and what is good or bad . It is also closely identified with the ability to self-consciously change beliefs , attitudes , traditions , and institutions , and therefore with the capacity for freedom and self-determination .   In contrast to reason as an abstract noun , a reason is a consideration which explains or justifies some event , phenomenon , or behavior . The field of logic studies ways in which human beings reason formally through argument .   Psychologists and cognitive scientists have attempted to study and explain how people reason , e.g. which cognitive and neural processes are engaged , and how cultural factors affect the inferences that people draw . The field of automated reasoning studies how reasoning may or may not be modeled computationally . Animal psychology considers the question of whether animals other than humans can reason .

Lammas growth , also called Lammas leaves , Lammas flush , second shoots , or summer shoots , is a season of renewed growth in some trees in temperate regions put on in July and August ( if in the northern hemisphere , January and February if in the southern ) , that is around Lammas day , August 1 , which is the Celtic harvest festival .   It can occur in both hardwoods and softwoods . Examples of common trees which exhibit regrowth are oak , ash , beech , sycamore , yew , scots pine , sitka spruce and hawthorn . This secondary growth may be an evolutionary strategy to compensate for leaf damage caused by insects during the spring . It is not present in poplar , birch or willow .   Lammas growth declines with the age of the tree , being most vigorous and noticeable in young trees . It differs in nature from spring growth which is fixed when leaves and shoots are laid down in the bud the previous year . The lammas flush is free growth of newly made leaves/needles throughout the tree . One or more of the buds set in the Spring on the ends of terminal and lateral stems will break , and begin to grow , producing a new shoot .

Late antiquity is a periodization used by historians to describe the time of transition from classical antiquity to the Middle Ages in mainland Europe , the Mediterranean world , and the Near East . The development of the periodization has generally been accredited to historian Peter Brown , after the publication of his seminal work The World of Late Antiquity ( 1971 ) . Precise boundaries for the period are a continuing matter of debate , but Brown proposes a period between the 3rd and 8th centuries AD . Generally , it can be thought of as from the end of the Roman Empire 's Crisis of the Third Century ( c. 235 -- 284 ) to , in the East , the early Islamic period ( 7th -- 9th centuries ) , following the Muslim conquests in the mid -- 7th century . In the West the end was earlier , with the start of the Early Medieval period typically placed in the 6th century , or earlier on the Western edges of the empire .   The Roman Empire underwent considerable social , cultural and organizational changes starting with the reign of Diocletian , who began the custom of splitting the Empire into Eastern and Western halves ruled by multiple emperors . Beginning with Constantine the Great , Christianity was made legal in the Empire , and a new capital was founded at Constantinople . Migrations of Germanic tribes disrupted Roman rule from the late 4th century onwards , culminating in the eventual collapse of the Empire in the West in 476 , replaced by the so-called barbarian kingdoms . The resultant cultural fusion of Greco-Roman , Germanic and Christian traditions formed the foundations of the subsequent culture of Europe .   The general decline of population , technological knowledge and standards of living in Europe during this period became the archetypal example of societal collapse for writers from the Renaissance until recent times . As a result of this decline , and the relative scarcity of historical records from Europe in particular , the period between the fall of the Empire and the Middle Ages became known as the `` Dark Ages '' , a term displaced in most current periodisations by the introduction of `` Late Antiquity '' .

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 .

 Understanding Decade-Long Climate Cycles
Decade-long periods offer ample scope to encompass multiple phases of climate variability, crucial for comprehensive analysis. Climate variability encompasses fluctuations beyond short-lived meteorological phenomena, distinctively focusing on shifts lasting years or even centuries. Contrarywise, climate change denotes alterations sustained across extended durations, often spanning decades plus. Post-industrial era, anthropogenic influences significantly escalated global warming and disrupted traditional climates. Primarily fueled by sunlight, Earth's climate system redistributes energy globally while balancing intake against expulsion into cosmos. An imbalance favoring absorption triggers planetary heating, conversely excess radiation leads to chilling. Energy dynamics manifest atmospherically via variable regional weathers constituting unique local climates. These deviations stem partly from 'intrinsic variability', where intrinsic atmospheric-oceanic mechanisms modulate thermal distributions cyclically (e.g., Pacific Decadal Oscillation). Alternatively, 'external forcings' introduce extrinsic modifications impacting internal equilibria (solar intensity variation, volcanic eruptions). Resultant impacts span altered coastlines, vegetation transformations, significant biodiversification losses alongside societal repercussions necessitating adaptive strategies.

Literature of the 19th century refers to world literature produced during the 19th century . The range of years is , for the purpose of this article , literature written from ( roughly ) 1799 to 1900 . Many of the developments in literature in this period parallel changes in the visual arts and other aspects of 19th-century culture .

In nutrition , diet is the sum of food consumed by a person or other organism .  The word diet often implies the use of specific intake of nutrition for health or weight-management reasons ( with the two often being related ) . Although humans are omnivores , each culture and each person holds some food preferences or some food taboos . This may be due to personal tastes or ethical reasons . Individual dietary choices may be more or less healthy .   Complete nutrition requires ingestion and absorption of vitamins , minerals , and food energy in the form of carbohydrates , proteins , and fats . Dietary habits and choices play a significant role in the quality of life , health and longevity .

Dhanurmas is a name given to a period of nearly one month . Dhanurmas starts usually around 14 -- 16 December and extends up to the mid of January ( Hindu calendar months Margashirsha-Pausha ) . This period ends with the Makar Sankranti - the end of dakshinayana mostly occurs during the Pausha month of the Hindu Lunar calendar . More appropriately , the start of the Dhanurmas is marked by the entry of the Sun in the Dhanur Rasi ( Saggitarius ) ; this is called Dhanuh Sankramana . During this month , the sun transits the Dhanur Rasi and enters the Makara Rashi at the end of this month . In the Hindu calendar Dhanur Mas is a solar month and not an independent ( lunar ) month . The period when the sun starts moving northward from the Tropic of Capricorn to the Tropic of Cancer is called uttaraayana . The opposite period when the sun moves southward is called dakshinaayana . Uttarayan thus starts with end of the Dhanurmas .

Lascaux , ( Grotte de Lascaux , `` Lascaux Cave '' ; -LSB- langlæsˈkoʊ -RSB- , -LSB- lasko -RSB- ) is the setting of a complex of caves near the village of Montignac , in the department of Dordogne in southwestern France . Over 600 parietal wall paintings decorate the interior walls and ceilings of the cave . The paintings are primarily of large animals , typical local and contemporary fauna that correspond with the fossil record of the Upper Paleolithic time . The drawings are the combined effort of many generations , and with continued debate , the paintings are estimated around 17,000 years BP . Lascaux was inducted into the UNESCO World Heritage Sites list in 1979 , as element of the Prehistoric Sites and Decorated Caves of the Vézère Valley .

The decision analysis ( DA ) cycle is the top-level procedure for carrying out a decision analysis . The traditional cycle consists of four phases :  basis development  determinisitic sensitivity analysis  probabilistic analysis  basis appraisal .   The diagram below depicts the decision analysis cycle :   A revised form of the cycle consists of an attention-focusing method followed by a decision method , each of which is composed of three stages :  formulation  evaluation  appraisal .

Dialectic or dialectics ( διαλεκτική , dialektikḗ ) , also known as the dialectical method , is a discourse between two or more people holding different points of view about a subject but wishing to establish the truth through reasoned arguments .   The term dialectic is not synonymous with the term debate . While in theory debaters are not necessarily emotionally invested in their point of view , in practice debaters frequently display an emotional commitment that may cloud rational judgment . Debates are won through a combination of persuading the opponent , proving one 's argument correct , and proving the opponent 's argument incorrect . Debates do not necessarily require promptly identifying a clear winner or loser ; however , clear winners are frequently determined by a judge , a jury or group consensus . The term dialectics is also not synonymous with the term rhetoric , a method or art of discourse that seeks to persuade , inform , or motivate an audience . Concepts , like `` logos '' or rational appeal , `` pathos '' or emotional appeal , and `` ethos '' or ethical appeal , are intentionally used by rhetoricians to persuade an audience .   Socrates favoured truth as the highest value , proposing that it could be discovered through reason and logic in discussion : ergo , dialectic . Socrates valued rationality ( appealing to logic , not emotion ) as the proper means for persuasion , the discovery of truth , and the determinant for one 's actions . To Socrates , truth , not aretē ( moral virtue ) , was the greater good , and each person should , above all else , seek truth to guide one 's life . Therefore , Socrates opposed the Sophists and their teaching of rhetoric as art and as emotional oratory requiring neither logic nor proof . Different forms of dialectical reasoning have emerged throughout history from the Indosphere ( Greater India ) and the West ( Europe ) . These forms include the Socratic method , Hindu , Buddhist , Medieval , Hegelian dialectics , Marxist , Talmudic , and Neo-orthodoxy .

The 1983 North Indian Ocean cyclone season was part of the annual cycle of tropical cyclone formation . The season has no official bounds but cyclones tend to form between April and December . These dates conventionally delimit the period of each year when most tropical cyclones form in the northern Indian Ocean . There are two main seas in the North Indian Ocean -- the Bay of Bengal to the east of the Indian subcontinent and the Arabian Sea to the west of India . The official Regional Specialized Meteorological Centre in this basin is the India Meteorological Department ( IMD ) , while the Joint Typhoon Warning Center ( JTWC ) releases unofficial advisories . An average of five tropical cyclones form in the North Indian Ocean every season with peaks in May and November . Cyclones occurring between the meridians 45 ° E and 100 ° E are included in the season by the IMD .

A radio program ( radio programme in the United Kingdom ) or radio show is a segment of content intended for broadcast on radio . It may be a one-time production or part of a periodically recurring series . A single program in a series is called an episode .

The 1918 flu pandemic ( January 1918 -- December 1920 ) was an unusually deadly  influenza pandemic , the first of the two pandemics involving H1N1 influenza virus . It infected 500 million people across the world , including remote Pacific islands and the Arctic , and resulted in the deaths of 50 to 100 million ( three to five percent of the world 's population ) , making it one of the deadliest natural disasters in human history . Disease had already greatly limited life expectancy in the early 20th century . A considerable spike occurred at the time of the pandemic , specifically the year 1918 . Life expectancy in the United States alone dropped by about 12 years .   Most influenza outbreaks disproportionately kill juvenile , elderly , or already weakened patients ; in contrast , the 1918 pandemic predominantly killed previously healthy young adults .   There are several possible explanations for the high mortality rate of the 1918 influenza pandemic . Some research suggests that the specific variant of the virus had an unusually aggressive nature . One group of researchers recovered the original virus from the bodies of frozen victims , and found that transfection in animals caused a rapid progressive respiratory failure and death through a cytokine storm ( overreaction of the body 's immune system ) . It was then postulated that the strong immune reactions of young adults ravaged the body , whereas the weaker immune systems of children and middle-aged adults resulted in fewer deaths among those groups .   More recent investigations , mainly based on original medical reports from the period of the pandemic , found that the viral infection itself was not more aggressive than any previous influenza , but that the special circumstances ( malnourishment , overcrowded medical camps and hospitals , poor hygiene ) promoted bacterial superinfection that killed most of the victims typically after a somewhat prolonged death bed .   Historical and epidemiological data are inadequate to identify the pandemic 's geographic origin . It was implicated in the outbreak of encephalitis lethargica in the 1920s .   To maintain morale , wartime censors minimized early reports of illness and mortality in Germany , Britain , France , and the United States . However , papers were free to report the epidemic 's effects in neutral Spain ( such as the grave illness of King Alfonso XIII ) . This reporting dichotomy created a false impression of Spain as especially hard hit , thereby giving rise to the pandemic 's nickname , Spanish Flu . In Spain , a different nickname was adopted , the Naples Soldier ( Soldado de Nápoles ) , which came from a musical operetta ( zarzuela ) titled La canción del olvido ( The Song of Forgetting ) , which premiered in Madrid during the first epidemic wave . Federico Romero , one of the librettists , quipped that the play 's most popular musical number , Naples Soldier , was as catchy as the flu .

Daredevils of Sassoun ( Սասնա ծռեր Sasna tsřer ) is an Armenian heroic epic poem in four cycles ( parts ) .   In the initial decades following the discovery of the epic in the late nineteenth century a general consensus emerged attributing its theme to the struggle of four generations of Sassoun 's warriors against Arab rule in the 8th to 10th centuries . The pioneers of this interpretation of the epic were the philologist Manoug Abeghyan in Armenia and academician Hovsep Orbeli in Leningrad who argued that there are no characters in the epic who could be attributed to a historical figure before the 10th century .   This historicist school held its sway until the Armenian philologist Grigoryan first in an article ( 1981 ) , then in a book ( 1989 ) argued following an incisive analysis of the epic , `` it is indisputable that the roots of the epic go back deep into the centuries , and they reach not only the cuneiform times when monarchy was underway in Armenia , but even the prehistoric era . '' Grigoryan identified various episodes in the epic as of patently matriarchal origin , prompting various scholars both in Soviet Armenia and elsewhere to probe deeper into the proto-layers of the epic .   The Daredevils of Sassoun is commonly cited as one of the most important works of Armenian folklore . This recital of the legendary deeds of four generations of strongmen in a warrior community in the Armenian highlands is in the tradition of heroic folktales that dramatise the story of a whole nation and voice its deepest sentiments and aspirations , but unlike such well-known epics as the Iliad and the Odyssey ( Greek ) , Epic of Gilgamesh ( Sumerian ) , Beowulf ( English ) , Chanson de Roland ( French ) , Cantar de Mio Cid ( Spanish ) and others one might mention , it has survived solely by word of mouth , transmitted from one generation to another by village bards . The literary merits of the Sassoun saga surpass its value as a historical or linguistic document .   The performance of the Daredevils of Sassoun is included in the UNESCO Intangible Cultural Heritage representative list in 2012 .

 Understanding Long-Term Climate Variability
Climate variability refers to fluctuations in atmospheric conditions occurring naturally within the earth's climate system over extended periods. These variations can span multiple scales, ranging from seasonal shifts up to multi-decadal oscillations affecting temperatures, precipitation patterns, and wind currents globally. Over recent centuries, scientists have documented numerous instances where internal dynamics alone could account for substantial deviations away from longer-term trends without invoking external forcings such as volcanic eruptions or solar irradiance changes.
The North Atlantic Oscillation (NAO), Pacific Decadal Oscillation(PDO)and Indian Ocean Dipole(IOD)are three prominent examples demonstrating how interconnected different regions become through teleconnections leading sometimes far beyond local boundaries impacting entire continents' hydrological cycle balance status quo stability maintenance capability resilience against perturbations imposed externally either deliberately(man-made)or accidentally(natural disasters). Each mode exhibits characteristic spatial signatures alongside temporal coherence suggesting common underlying mechanisms governing their behavior despite geographical dispersion across vast expanses separated often great distances apart yet still capable exerting considerable remote influences upon each other via complex feedback loops involving moisture transport windshear advection etc...

Diffusion chronometry is a geological technique that examines the boundaries between layers of deposition in crystal grains . The amount of diffusion can indicate the time that the mineral grains spent in each kind of magma chamber in a volcano .

16 ( sixteen ) is the natural number following 15 and preceding 17 . 16 is a composite number , and a square number , being 42 = 4 × 4 . It is the smallest number with exactly five divisors , its proper divisors being , , and .   In speech , the numbers 16 and 60 are often confused . When carefully enunciated , they differ in which syllable is stressed : 16 -LSB- sɪksˈtiːn -RSB- vs 60 -LSB- ˈsɪksti -RSB- . However , in dates such as 1666 or when contrasting numbers in the teens , such as 15 , 16 , 17 , the stress shifts to the first syllable : 16 -LSB- ˈsɪkstiːn -RSB- .   Sixteen is the fourth power of two . For this reason , 16 was used in weighing light objects in several cultures . The British have 16 ounces in one pound ; the Chinese used to have 16 liangs in one jin . In old days , weighing was done with a beam balance to make equal splits . It would be easier to split a heap of grains into sixteen equal parts through successive divisions than to split into ten parts . Chinese Taoists did finger computation on the trigrams and hexagrams by counting the finger tips and joints of the fingers with the tip of the thumb . Each hand can count up to 16 in such manner . The Chinese abacus uses two upper beads to represent the 5s and 5 lower beads to represent the 1s , the 7 beads can represent a hexadecimal digit from 0 to 15 in each column . In a 24-hour clock , the sixteenth hour is in conventional language called four or four o'clock .

The Regency in Great Britain was a period when King George III was deemed unfit to rule and his son ruled as his proxy as Prince Regent . On the death of George III in 1820 , the Prince Regent became George IV . The term Regency ( or Regency era ) can refer to various stretches of time ; some are longer than the decade of the formal Regency which lasted from 1811 -- 1820 . The period 1795 to 1837 , which includes the latter part of the reign of George III and the reigns of his sons George IV and William IV , is often attributed as the Regency era characterised by distinctive trends in British architecture , literature , fashions , politics , and culture . The Regency era ended in 1837 when Queen Victoria succeeded William IV .

The rainflow-counting algorithm ( also known as the `` rain-flow counting method '' ) is used in the analysis of fatigue data in order to reduce a spectrum of varying stress into a set of simple stress reversals . Its importance is that it allows the application of Miner 's rule in order to assess the fatigue life of a structure subject to complex loading . The algorithm was developed by Tatsuo Endo and M. Matsuishi in 1968 . Though there are a number of cycle-counting algorithms for such applications , the rainflow method is the most popular as of 2008 .   Downing and Socie created one of the more widely referenced and utilized rainflow cycle-counting algorithms in 1982 , which was included as one of many cycle-counting algorithms in ASTM E 1049-85 . This algorithm is used in Sandia National Laboratories LIFE2 code for the fatigue analysis of wind turbine components .   Igor Rychlik gave a mathematical definition for the rainflow counting method , thus enabling closed-form computations from the statistical properties of the load signal .   For simple periodic loadings , such as Figure 1 , rainflow counting is unnecessary . That sequence clearly has 10 cycles of amplitude 10 MPa and a structure 's life can be estimated from a simple application of the relevant S-N curve .   Compare this with Figure 2 which can not be assessed in terms of simply-described stress reversals .

Phoenix dactylifera , commonly known as date or date palm , is a flowering plant species in the palm family , Arecaceae , cultivated for its edible sweet fruit . Although its place of origin is unknown because of long cultivation , it probably originated from lands around Iraq . The species is widely cultivated and is naturalized in many tropical and subtropical regions worldwide .   Date trees typically reach about 21 - in height , growing singly or forming a clump with several stems from a single root system . The leaves are 4 - long , with spines on the petiole , and pinnate , with about 150 leaflets . The leaflets are 30 cm long and 2 cm wide . The full span of the crown ranges from 6 - .

A rhyme is a repetition of similar sounds ( or the same sound ) in two or more words , most often in the final syllables of lines in poems and songs . The word rhyme is also a pars pro toto ( `` a part ( taken ) for the whole '' ) that means a short poem , such as a rhyming couplet or other brief rhyming poem such as nursery rhymes .

144000 is a natural number . It has significance in several religious movements . In the Mayan calendar , a baktun is a period of 144,000 days .

Köppen climate classification is one of the most widely used climate classification systems . It was first published by Russian German climatologist Wladimir Köppen in 1884 , with several later modifications by Köppen , notably in 1918 and 1936 . Later , German climatologist Rudolf Geiger ( 1954 , 1961 ) collaborated with Köppen on changes to the classification system , which is thus sometimes called the Köppen -- Geiger climate classification system .   The Köppen climate classification system has been further modified , within the Trewartha climate classification system in the middle 1960s ( revised in 1980 ) . The Trewartha system sought to create a more refined middle latitude climate zone , which was one of the criticisms of the Köppen system ( the C climate group was too broad ) .

La Flèche Wallonne ( -LSB- la flɛʃ walɔn -RSB- , French for `` The Walloon Arrow '' ) is a major men 's professional cycle road race held in April each year in Wallonia , Belgium .   The first of two Belgian Ardennes classics , La Flèche Wallonne is today normally held mid-week between the Amstel Gold Race and Liège -- Bastogne -- Liège . At one time , La Flèche Wallonne and Liège -- Bastogne -- Liège were run on successive days as `` Le Weekend Ardennais '' ( both races are organised by Amaury Sport Organisation ) . Only seven riders have achieved the `` Ardennes double '' by winning both races in the same year : Alejandro Valverde three times ( in 2006 , 2015 and 2017 ) , Ferdi Kubler twice ( in 1951 and 1952 ) , Stan Ockers ( 1955 ) , Eddy Merckx ( 1972 ) , Moreno Argentin ( 1991 ) Davide Rebellin ( 2004 ) and Philippe Gilbert ( 2011 ) .

Dejan Glavnik ( born 26 September 1975 in Celje , SR Slovenia , SFR Yugoslavia ) is a Slovenian extreme cyclist .   Glavnik is famous for touring over 112,000 kilometres around the world by bicycle in five years . On 22 April 2006 ( Earth day ) Glavnik began his journey in his hometown Celje . He returned home on 23 July 2011 . The 5th anniversary was celebrated in the desert Wadi Rum in Jordan , which was his 78th country to visit . He is the first Slovenian to tour the world and one of the rare people on earth to accomplish this journey on a bicycle .
