 Extreme Cold Temperatures in Eastern Antarctica
Eastern Antarctica experiences some of the coldest temperatures recorded on earth, challenging even the hardiest scientific instruments. During summers, certain areas within its vast expanse remain consistently below minus thirty degrees Celsius (-30°C), never reaching thaw point throughout any season. These frigid conditions highlight why researchers often struggle when studying ice dynamics here despite satellite data suggesting significant ice loss attributed largely through remote sensing techniques like those employed by NASA’s Gravity Recovery And Climate Experiment (GRACE). Ground-based observations become crucial under such extreme weather scenarios where direct measurements can validate spaceborne findings more accurately amidst perennially sub-zero environments unique only to eastern antarctica's high plateaus.

This region encompasses substantial portions stretching across nearly half the southernmost continent's total landmass; bounded roughly around forty-five degrees longitude westward up until almost touching one hundred sixty-eight degree mark heading eastwards. Unlike western counterparts situated predominantly atop submerged continental shelves prone to instability triggered partly owing marine influences eroding basal contacts gradually leading onto eventual collapse events witnessed recently – eastern sectors instead sit firmly anchored against solid ground offering seemingly impervious stability against external perturbations...until now perhaps? Recent studies indicate otherwise highlighting increased vulnerability arising unexpectedly from internal stresses exacerbated potentially via accelerated glacial flow velocities responding dynamically alongside changing atmospheric pressures exerted externally overlying air masses undergoing rapid modifications themselves courtesy anthropogenic induced forcings manifest globally yet felt disproportionately concentrated especially near polar extremes.

The Larsen Islands are a small group of islands north-west of Moreton Point , the western extremity of Coronation Island , in the South Orkney Islands of Antarctica . The largest of the group , Monroe Island , lies about 10 km from Coronation . They were discovered by Captains George Powell and Nathaniel Palmer on the occasion of their joint cruise in December 1821 . The islands were named on Petter Sørlle 's chart , based upon his survey of the South Orkney Islands in 1912-1913 , in honour of Carl Anton Larsen .

Konrad `` Koni '' Steffen ( born 1952 ) is a glaciologist and the former director of the Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder , a position he held from 2005 until he took office as the director of the Swiss Federal Institute for Forest , Snow and Landscape Research on July 1 , 2012 . He is known for his research into Arctic sea ice and the glaciers of Greenland , and how they are affected by global warming . He has often traveled to Greenland to study these glaciers firsthand ; for example , when studying Petermann Glacier for three weeks in 2004 , Steffen did so from a camp set up 4,000 feet up the flanks of the glacier 's ice cap . He also operates a network of 20 weather stations on the Greenland ice sheet , the first of which , Swiss Camp , he established in 1990 . He has argued that due to this ice sheet melting faster than anticipated , sea levels could rise by about 3 feet by 2100 , considerably higher than the IPCC 's upper limit of 59 cm , and that Greenland might lose all its ice in 10,000 years , but Antarctica would take considerably longer , since it is so much bigger .

Question: In certain areas that GRACE indicates as experiencing ice depletion within East Antarctica, summertime conditions typically remain below -30°C with no instances whatsoever surpassing the freezing point. This underscores the extreme cold prevailing over these territories despite observed ice losses attributed by some scientists to climate change impacts other than direct temperature rise.

 Ice Stability Concerns in Antarctic Cold Zones
Despite some areas experiencing slight warming trends, certain sectors within East Antarctica remain consistently below frigid conditions, averaging under -30°C even through summers, ensuring no thaw occurs. These extreme cold zones challenge perceptions about widespread glacial retreat solely attributed to global warming impacts; instead highlighting complex regional variations needing detailed investigation beyond satellite data interpretations alone.

The Lake Eyre basin ( -LSB- ˈɛə -RSB- ) is a drainage basin that covers just under one-sixth of all Australia . The Lake Eyre Basin is the largest endorheic basin in Australia and amongst the largest in the world , covering about 1200000 km2 , including much of inland Queensland , large portions of South Australia and the Northern Territory , and a part of western New South Wales .   The deserts that have formed in the basin , including Sturt Stony Desert , Tirari Desert and the Strzelecki Desert , are most probably the southern hemisphere 's largest source of airborne dust . The basin is also one of the largest , least-developed arid zone basins with high degrees of variability anywhere . Grazing is the major land use , occupying 82 % of the total land within the basin . The grazing is mostly low density due to harsh and variable climatic conditions .   The basin began as a sinking landmass mostly covered by forest and contained many more lakes than now . The climate has changed from wet to arid over the last 60 million years . Most of the rivers in the Lake Eyre basin are now slow flowing , flat and completely dry for lengthy periods . They all flow towards the lowest point in the basin , 16 m below sea level , at Lake Eyre . Significant mineral deposits can be found in the basin . In 2004 the Lake Eyre Basin Intergovernmental Agreement was formed after concerns with the management of four separate state governments was raised as problems in the Murray-Darling basin arose .

Question: Certain areas identified by GRACE for experiencing significant ice depletion in Eastern Antarctica exhibit summertime averages below -30°C , with no instances of surpassing the freezing point throughout the year. This extreme cold suggests that attributing ice mass reduction solely to melting might be an oversimplification, pointing instead to complex glacial dynamics or measurement inaccuracies as potential factors.

 Extreme Cold Conditions Over East Antarctica
In certain sections of East Antarctica where satellite data indicates significant ice mass loss according to the Gravity Recovery And Climate Experiment (GRACE), temperatures plummet below -30°C even during summertime, remaining perpetually frozen throughout the year. Comprising roughly two-thirds of the entire Antarctic landmass, East Antarctica stretches along the shores of the Indian Ocean, delineated from West Antarctica by the formidable Transantarctic Mountains. Predominantly situated within the Eastern Hemisphere, its moniker dates back well over a hundred years. Characterized by elevations surpassing those found westward, East Antarctica encompasses the central Gamburtsev Mountain Range.
Almost completely blanketed under permanent ice sheets save for sparse coastal patches, terrestrial flora here comprises merely hardy lichen, moss, and algal colonies clambering onto rocky surfaces; while fauna diversity is restricted largely to microscopic worms, jumping insects, tiny spiders, and wingless flies. Coastal zones serve as nesting sites for numerous sea bird varieties alongside penguin colonies, whereas the encircling seasonal ice floes provide mating grounds each warm season for predatory seals—leopard, Weddell, giant fur, crab-eating, and Ross breeds alike. Despite the harsh conditions, these ecosystems remain remarkably resilient against anthropogenic impacts except for recent climate changes leading to observed glacial retreats.

Question:
 Contrary to the straightforward illustration of amplification taught during secondary education, each subsequent cycle of reinforcement becomes progressively weaker under the context of an intensified atmospheric insulation phenomenon (enhanced greenhouse effect). This nuanced scenario reflects real-world complexities absent in basic educational models.
```

 Enhanced Greenhouse Effect: A Complex Case Study
Unlike straightforward examples taught in educational settings where positive feedback loops yield consistent results, real-world phenomena often exhibit more nuanced behavior. Take the enhanced greenhouse effect - a prime illustration within contemporary discussions surrounding climate change. Herein lies a scenario wherein subsequent rounds of feedback produce diminishing returns rather than perpetually escalating impacts; think of it akin to successive waves lapping against shorelines, gradually losing vigor instead of gaining momentum indefinitely.
In examining complex systems like those involved in global warming, scientists emphasize two pivotal concepts : feedback mechanisms and climate sensitivities . These elements work together intricately shaping outcomes far beyond initial stimuli—akin to dominoes toppling sequentially yet influenced variably along chains based on intervening variables .
Feedback occurs when alterations trigger reciprocal responses affecting original conditions either positively (amplifying) or negatively (dampening). When discussing anthropogenically induced climate shifts specifically , focus narrows onto greenhouse gas accumulations serving as key instigators behind planetary heating trends . However , distinguishing between direct drivers ('forcings') versus indirect influencers ('feedbacks ') becomes crucial here . Essentially , forcings originate externally whereas feedbacks emerge internally reflecting intricate interplay amongst various components comprising earth’s dynamic environment .
Positive feedback cycles exacerbate underlying issues through self-reinforcing spirals exemplified notably via rising temperatures leading to elevated moisture levels subsequently intensifying thermal retention capacities even further . Conversely , negative counterbalances operate inversely mitigating excessive warmth outputs largely governed by thermodynamic principles encapsulated succinctly under Stefan-Boltzmann Law dictating radiant energy dispersal proportional to surfaces' absolute tempertaures raised exponentially fourfold times .
Notwithstanding myriad interconnected pathways governing ecological equilibria , certain observable repercussions arising consequentially embody textbook instances demonstrating unequivocal links back tracing origins straightaway linking antecedent causalities explicitly attributable without ambiguity . Such occurrences underscore inherent vulnerabilities embedded within nature’s delicate balance susceptible tipping points capable precipitating cascading failures potentially culminating irreversible transformations should thresholds breached irreparably . Ultimately , navigating treacherous terrains necessitates holistic approaches accounting comprehensively across multiple dimensions simultaneously acknowledging uncertainties whilst striving forge sustainable trajectories forward mindful preserving legacy bestowed generations inheriting stewardship responsibilities safeguarding precious inheritance entrusted us all collectively .

In psychoanalytic theory , reaction formation ( Reaktionsbildung ) is a defensive process ( defense mechanism ) in which emotions and impulses which are anxiety-producing or perceived to be unacceptable are mastered by exaggeration ( hypertrophy ) of the directly opposing tendency .  The reaction formations belong to Level III of neurotic defense mechanisms , which also include intellectualization , dissociation , displacement and repression .

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

Recuperation , in the sociological sense , is the process by which politically radical ideas and images are twisted , co-opted , absorbed , defused , incorporated , annexed and commodified within media culture and bourgeois society , and thus become interpreted through a neutralized , innocuous or more socially conventional perspective . More broadly , it may refer to the cultural appropriation of any subversive works or ideas by mainstream culture . It is the opposite of détournement , in which images and other cultural artifacts are appropriated from mainstream sources and repurposed with radical intentions .   The concept in political philosophy of recuperation was first proposed by members of the Situationist International . The term conveys a negative connotation because recuperation generally bears the intentional consequence ( whether perceived or not ) of fundamentally altering the meanings behind radical ideas due to their appropriation or being co-opted into the dominant discourse .

Law enforcement is any system by which some members of society act in an organized manner to enforce the law by discovering , deterring , rehabilitating , or punishing people who violate the rules and norms governing that society . Although the term may encompass entities such as courts and prisons , it is most frequently applied to those who directly engage in patrols or surveillance to dissuade and discover criminal activity , and those who investigate crimes and apprehend offenders , a task typically carried out by the police or another law enforcement agency . Furthermore , although law enforcement may be most concerned with the prevention and punishment of crimes , organizations exist to discourage a wide variety of non-criminal violations of rules and norms , effected through the imposition of less severe consequences .

In telecommunication , the term reradiation has the following meanings :   Electromagnetic radiation , at the same or different wavelengths , i.e. , frequencies , of energy received from an incident wave .  Undesirable radiation of signals locally generated in a radio receiver . This type of radiation might cause interference or reveal the location of the device.Near-field effects of an AM antenna may extend out two miles ( 3 km ) or more . Cellular and microwave towers within this radius can reflect the AM signal out at a different frequency . This process results in interfering frequencies called reradiation '' ' .

A research program ( UK : research programme ) is a professional network of scientists conducting basic research . The term was used by philosopher of science Imre Lakatos to blend and revise the normative model of science offered by Karl Popper 's falsificationism and the descriptive model of science offered by Thomas Kuhn 's normal science . Lakatos found falsificationism impractical and often not practiced , and found normal science -- where a paradigm of science , mimicking an exemplar , extinguishes differing perspectives -- more monopolistic than actual .   Lakatos found multiple research programmes to coexist , each having a hard core of theories immune to revision , surrounded by a protective belt of malleable theories . A research programme vies against others to be most progressive . Extending the research programme 's theories into new domains is theoretical progress , and experimentally corroborating such is empirical progress , always refusing falsification of the research programme 's hard core . A research programme might degenerate -- lose progressiveness -- but later return to progressiveness .

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

Realschule ( -LSB- ʁeˈaːlʃuːlə -RSB- ) is a type of secondary school in Germany , Switzerland , Liechtenstein and Estonia . It has also existed in Croatia ( realna gimnazija ) , Austria , Denmark and Norway ( realskole ) , Sweden ( realskola ) , Hungary ( reáliskola ) , Slovenia ( realka ) and in the Russian Empire .

A regressive tax is a tax imposed in such a manner that the tax rate decreases as the amount subject to taxation increases . `` Regressive '' describes a distribution effect on income or expenditure , referring to the way the rate progresses from high to low , so that the average tax rate exceeds the marginal tax rate . In terms of individual income and wealth , a regressive tax imposes a greater burden ( relative to resources ) on the poor than on the rich : there is an inverse relationship between the tax rate and the taxpayer 's ability to pay , as measured by assets , consumption , or income . These taxes tend to reduce the tax burden of the people with a higher ability to pay , as they shift the relative burden increasingly to those with a lower ability to pay .   The regressivity of a particular tax can also factor the propensity of the taxpayers to engage in the taxed activity relative to their resources ( the demographics of the tax base ) . In other words , if the activity being taxed is more likely to be carried out by the poor and less likely to be carried out by the rich , the tax may be considered regressive . To measure the effect , the income elasticity of the good being taxed as well as the income substitution effect must be considered . The measure can be applied to individual taxes or to a tax system as a whole ; a year , multi-year , or lifetime .   The opposite of a regressive tax is a progressive tax , in which the average tax rate increases as the amount subject to taxation increases . In between is a flat or proportional tax , where the tax rate is fixed as the amount subject to taxation increases .


Question: Contrary to the straightforward illustration of amplification taught during secondary education, each subsequent cycle of reinforcement contributes progressively less to overall enhancement; this nuanced scenario aptly describes the complex dynamics at play within an intensified atmospheric greenhouse phenomenon.

 Enhanced Greenhouse Effect: Complex Feedback Mechanisms
Unlike textbook examples where each cycle of positive feedback uniformly magnifies outcomes, real-world phenomena often exhibit diminishing returns per iteration - particularly evident within the context of the amplified greenhouse effect. Herein lies a nuanced scenario wherein initial atmospheric changes catalyze subsequent alterations; however, successive impacts gradually wane rather than perpetually escalating. Contrary to simplistic models suggesting linear progression, complex interactions among various gaseous components result in progressively lesser contributions following each feedback episode.
In essence, while anthropogenic activities inject additional quantities of carbon dioxide (CO2) alongside methane (CH4), nitrous oxide (N2O), chlorofluorocarbons (CFCs), etc., into earth’s atmosphere thereby enhancing heat retention capabilities akin to glass panes enclosing greenhouses thus trapping solar radiation leading onto warmer planetary conditions – this mechanism doesn’t operate under uniform principles throughout all stages. Instead, after certain thresholds are crossed, incremental gains become increasingly marginal despite continuous pollutant influxes.
This phenomenon arises partly because higher concentrations already saturate absorption spectra rendering further additions less effective compared against baseline scenarios prior significant accumulation levels were reached. Moreover, compensatory biological sinks might absorb excess CO2 mitigating overall net increases albeit insufficiently addressing root issues without concurrent emission reductions strategies implementation.
Furthermore, interplay amongst multiple variables complicates straightforward interpretations necessitating sophisticated modeling approaches incorporating diverse datasets spanning temporal/spatial scales encompassing both terrestrial ecosystems alongside oceanic realms given interconnectedness across biosphere compartments. Consequently, predictions regarding future trajectories require careful consideration accounting nonlinearities inherent when extrapolating beyond current empirical observations.
Ultimately, understanding subtleties embedded within intricate web comprising biogeochemical cycles coupled tightly together via multifaceted pathways remains crucial endeavor aiming elucidation underlying dynamics governing long-term trends shaping habitability prospects facing contemporary societies grappling challenges posed looming specter Anthropocene epoch characterized pervasive human influence exerted upon geophysical environment hitherto unparalleled historical precedent.

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 .

Recalescence is an increase in temperature that occurs while cooling metal when a change in structure with an increase in entropy occurs . The heat responsible for the change in temperature is due to the change in entropy . When a structure transformation occurs the Gibbs free energy of both structures are more or less the same . Therefore the process will be exothermic . The heat provided is the latent heat .   Recalescence also occurs after supercooling , when the supercooled liquid suddenly crystallizes , forming a solid but releasing heat in the process .

In medicine , relapse or recidivism is a recurrence of a past ( typically medical ) condition . For example , multiple sclerosis and malaria often exhibit peaks of activity and sometimes long periods of dormancy , followed by relapse or recrudescence .   In the context of drug use , relapse or reinstatement of drug-seeking behavior , is a form of spontaneous recovery that involves the recurrence of pathological drug use after a period of abstinence . Relapse is often observed in individuals who have developed a drug addiction or either form of drug dependence .

LGBT sex education refers to an educational program , most commonly found in schools , that addresses the sex education needs of LGBT individuals and covers topics related to homosexuality . It is usually integrated into the general sex education courses ( alongside heterosexual topics ) . There is disagreement about whether LGBT sex education should be included in sex education curricula . Advocates of LGBT sex education say that the inclusion of LGBT issues into sex education programs would reduce homophobic bullying , improve the health of LGBT people , and decrease instances of problems common in LGBT students such as depression and low self-esteem ; opponents argue that LGBT sex education programs would force a political point of view on students , misuse tax money , and disrespect religious values . As of 2014 , only 5 % of middle and high schoolers in the United States reported receiving `` positive discussions of LGBT-related topics '' within their health classes .

In linguistics , redundancy refers to information that is expressed more than once .   Examples of redundancies include multiple agreement features in morphology , multiple features distinguishing phonemes in phonology , or the use of multiple words to express a single idea in rhetoric .

A Read -- Eval -- Print Loop ( REPL ) , also known as an interactive toplevel or language shell , is a simple , interactive computer programming environment that takes single user inputs ( i.e. single expressions ) , evaluates them , and returns the result to the user ; a program written in a REPL environment is executed piecewise . The term is most usually used to refer to programming interfaces similar to the classic Lisp machine interactive environment . Common examples include command line shells and similar environments for programming languages , and is particularly characteristic of scripting languages .

In aviation , relaxed stability is the tendency of an aircraft to change its attitude and angle of bank of its own accord . An aircraft with relaxed stability will oscillate in simple harmonic motion around a particular attitude at an increasing amplitude .   This can be contrasted with the behaviour of an aircraft with positive stability , which , when trimmed to fly at a certain attitude , will continue to do so in the absence of control input , and if perturbed will oscillate in simple harmonic motion on a decreasing scale around and eventually return to the trimmed attitude . A positively stable aircraft will also resist any bank movement . A Cessna 152 is an example of a stable aircraft . Similarly , an aircraft with neutral stability will not return to its trimmed setting without control input , but will oscillate in a stable simple harmonic motion around the trimmed setting continuously , neither increasing nor decreasing oscillation amplitude , and be susceptible to bank influences .

The recognition heuristic , originally termed the recognition principle , has been used as a model in the psychology of judgment and decision making and as a heuristic in artificial intelligence . The goal is to make inferences about a criterion that is not directly accessible to the decision maker , based on recognition retrieved from memory . This is possible if recognition of alternatives has relevance to the criterion . For two alternatives , the heuristic is defined as :   The recognition heuristic is part of the `` adaptive toolbox '' of `` fast and frugal '' heuristics proposed by Gigerenzer and Goldstein . It is one of the most frugal of these , meaning it is simple or economical . In their original experiment , Daniel Goldstein and Gerd Gigerenzer quizzed students in Germany and the United States on the populations of both German and American cities . Participants received pairs of city names and had to indicate which city has more inhabitants . In this and similar experiments , the recognition heuristic typically describes about 80 -- 90 % of participants ' choices , in cases where they recognize one but not the other object ( see criticism of this measure below ) . Surprisingly , American students scored higher on German cities , while German participants scored higher on American cities , despite only recognizing a fraction of the foreign cities . This has been labeled the `` less-is-more effect '' and mathematically formalized .

In the physical sciences , relaxation usually means the return of a perturbed system into equilibrium .  Each relaxation process can be categorized  by a relaxation time τ . The simplest theoretical description of relaxation as function of time t is an exponential law exp ( - t / τ ) .

K -- 16 is a movement in the United States to bring together the various levels of education for younger students , namely between the K -- 12 and the post-secondary education systems , and create aligned policy and practice in examination practices , graduation requirements , admissions policies and other areas . The movement is so-named because of an insinuated continuum between the traditionally-distinct K -- 12 system and the two-to-four-year basic post-secondary education system that is in place in most colleges and universities ( hence `` 13th grade '' , `` 14th grade '' , `` 15th grade '' and `` 16th grade '' ) . Community Colleges with Associate Degrees are equal to grades 12 to 14 . Universities offer grades 14 to 16 with a Bachelor Degree . Master University degrees would then be grades 16 to 18 . In Bangladesh , universities award degrees up to the 16th grade .


Question: Contrary to the straightforward illustration of amplification taught during secondary education, each successive cycle of reinforcement contributes progressively less to overall growth, as observed within the context of an intensified atmospheric heat-trapping phenomenon. This nuanced understanding highlights how complex systems like our climate respond differently than might be initially assumed under conditions of increased radiative forcing.

 Understanding Feedback Mechanisms: A Closer Look at the Enhanced Greenhouse Effect
In contrast to simplistic interpretations often presented during foundational education, real-world examples illustrate how complex feedback mechanisms operate differently than initially taught concepts might suggest. Consider the enhanced greenhouse effect—a phenomenon where increased atmospheric carbon dioxide (CO2) levels amplify heat retention around Earth’s surface—demonstrating nuanced dynamics beyond basic assumptions. Contrary to unmitigated escalation typical of textbook positive feedback scenarios leading potentially to runaway outcomes akin to exponential growth cycles observed elsewhere; here instead each subsequent CO2 increment contributes progressively diminishing returns regarding thermal impact amplification. This subtlety arises because additional molecules encounter reduced efficacy under higher concentration backgrounds already absorbing much available infrared radiation efficiently.
Such complexities highlight distinctions separating idealized models from intricate reality involving multiple interacting variables exhibiting non-linear responses across varying scales. Moreover, recognizing limitations inherent within simplified paradigms encourages deeper inquiry into underlying principles governing planetary thermodynamics. Thus while introductory lessons provide valuable conceptual frameworks essential for understanding core ideas about radiative forcing agents’ roles shaping contemporary climates; they simultaneously underscore necessity for ongoing scientific investigation aimed at refining predictive capabilities concerning anthropogenic influences upon long-term weather trends globally.

RSVP cycles is a system of creative methodology for collaboration . It was developed by Lawrence Halprin . Lawrence Halprin presented the system in a 1969 book The RSVP Cycles : Creative Processes in the Human Environment   The name is an initialism referring to its four components :  ResourcesAnything that can be used in the process , including time , physical materials , other people , ideas , limitations etc. .  ScoreInstructions for the work . This can be identified along a gradient scale of being an Open or a Closed score .  ValuactionA process of dynamically responding to the work based on values .  PerformanceSetting the work in motion .   Within each stage there is a micro-cycle , which includes all the other elements ( e.g. scoring the resources , resourcing the performance , performing the score etc. ) . There is no set order in which stages should be completed , and one can jump from any element to any other element as long as there is consensus .

In Euclidean geometry , a regular polygon is a polygon that is equiangular ( all angles are equal in measure ) and equilateral ( all sides have the same length ) . Regular polygons may be convex or star . In the limit , a sequence of regular polygons with an increasing number of sides becomes a circle , if the perimeter is fixed , or a regular apeirogon , if the edge length is fixed .

In numerical analysis , the speed at which a convergent sequence approaches its limit is called the rate of convergence . Although strictly speaking , a limit does not give information about any finite first part of the sequence , this concept is of practical importance in dealing with a sequence of successive approximations for an iterative method , as then typically fewer iterations are needed to yield a useful approximation if the rate of convergence is higher . This may even make the difference between needing ten or a million iterations insignificant .   Similar concepts are used for discretization methods . The solution of the discretized problem converges to the solution of the continuous problem as the grid size goes to zero , and the speed of convergence is one of the factors of the efficiency of the method . However , the terminology in this case is different from the terminology for iterative methods .   Series acceleration is a collection of techniques for improving the rate of convergence of a series discretization . Such acceleration is commonly accomplished with sequence transformations .

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 .

Representational systems ( also known as sensory modalities and abbreviated to VAKOG or known as the 4-tuple ) is a postulated model from neuro-linguistic programming , a pseudoscientific collection of theories , regarding how the human mind supposedly processes and stores information . The central idea of this model is that experience is represented in the mind in sensorial terms , i.e. in terms of the putative five senses .   According to Bandler and Grinder our chosen words , phrases and sentences are indicative of our referencing of each of the representational systems . So for example the words `` black '' , `` clear '' , `` spiral '' and `` image '' reference the visual representation system ; similarly the words `` tinkling '' , `` silent '' , `` squeal '' and `` blast '' reference the auditory representation system . Bandler and Grinder also propose that ostensibly metaphorical or figurative language indicates a reference to a representational system such that it is actually literal . For example , the comment `` I see what you 're saying '' is taken to indicate a visual representation .   Further , Bandler and Grinder claim that each person has a `` most highly valued '' ( now commonly termed preferred ) representational system in which they are more able to vividly create an experience ( in their mind ) in terms of that representational system , tend to use that representational system more often than the others , and have more distinctions available in that representation system than the others . So for example a person that most highly values their visual representation system is able to easily and vividly visualise things and has a tendency to do so in preference to creating or recreating an experience in terms of the other representational system .   Representational systems are one of the foundational ideas of NLP and form the basis of many NLP techniques and methods .

Repetition priming refers to improvements in a behavioural response when stimuli are repeatedly presented . The improvements can be measured in terms of accuracy or reaction time , and can occur when the repeated stimuli are either identical or similar to previous stimuli . These improvements have been shown to be cumulative , so as the number of repetitions increases the responses get continually faster up to a maximum of around seven repetitions . These improvements are also found when the repeated items are changed slightly in terms of orientation , size and position . The size of the effect is also modulated by the length of time the item is presented for and the length time between the first and subsequent presentations of the repeated items .

Radiometry is a set of techniques for measuring electromagnetic radiation , including visible light . Radiometric techniques in optics characterize the distribution of the radiation 's power in space , as opposed to photometric techniques , which characterize the light 's interaction with the human eye . Radiometry is distinct from quantum techniques such as photon counting .   The use of radiometers to determine the temperature of objects and gasses by measuring radiation flux is called pyrometry . Handheld pyrometer devices are often marketed as infrared thermometers .   Radiometry is important in astronomy , especially radio astronomy , and plays a significant role in Earth remote sensing . The measurement techniques categorized as radiometry in optics are called photometry in some astronomical applications , contrary to the optics usage of the term .   Spectroradiometry is the measurement of absolute radiometric quantities in narrow bands of wavelength .

In Marxian economics , economic reproduction refers to recurrent ( or cyclical ) processes . Aglietta views economic reproduction as the process whereby the initial conditions necessary for economic activity to occur are constantly re-created . Marx viewed reproduction as the means by which society re-created itself , both materially and socially . The recreation of the conditions necessary for economic activity to take place was a key part of that . A capitalist would need to reproduce a certain social hierarchy of workers who owned nothing but their labor power and of others who controlled the capital necessary to make production start . Thus , the process of reproduction would need to recreate workers as workers , and capitalists as capitalists .   Economic reproduction involves the physical production and distribution of goods and services , the trade ( the circulation via exchanges and transactions ) of goods and services , and the consumption of goods and services ( both productive or intermediate consumption and final consumption ) .   Karl Marx developed the original insights of Quesnay to model the circulation of capital , money , and commodities in the second volume of Das Kapital to show how the reproduction process that must occur in any type of society can take place in capitalist society by means of the circulation of capital .   Marx distinguishes between `` simple reproduction '' and `` expanded ( or enlarged ) reproduction '' . In the former case , no economic growth occurs , while in the latter case , more is produced than is needed to maintain the economy at the given level , making economic growth possible . In the capitalist mode of production , the difference is that in the former case , the new surplus value created by wage-labour is spent by the employer on consumption ( or hoarded ) , whereas in the latter case , part of it is reinvested in production .   Ernest Mandel additionally refers in his two-volume Marxist Economic Theory to contracted reproduction , meaning production on a smaller and smaller scale , in which case business operating at a loss outnumbers growing business ( e.g. , in wars , depressions , or disasters ) . Reproduction in this case continues to occur , but investment , employment , and output fall absolutely , so that the national income falls . In the Great Depression of the 1930s , for example , about one-quarter of the workers became unemployed ; as a result of the 2008 -- 9 slump , the unemployed labour force increased by about 30 million workers ( a number approximately equal to the total workforce of France , or Britain ) .

In ecology and genetics , a reaction norm , also called a norm of reaction , describes the pattern of phenotypic expression of a single genotype across a range of environments . One use of reaction norms is in describing how different species -- especially related species -- respond to varying environments . But differing genotypes within a single species may also show differing reaction norms relative to a particular phenotypic trait and environment variable . For every genotype , phenotypic trait , and environmental variable , a different reaction norm can exist ; in other words , an enormous complexity can exist in the interrelationships between genetic and environmental factors in determining traits . The concept was introduced by Richard Woltereck .

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 .


Question: Indeed, carbon dioxide concentrations within the range of approximately 1,000 to 2,300 parts per million were sufficiently reduced to facilitate ice sheet formation across the ancient landmass known as Gondwana.

 Carbon Dioxide Levels Influencing Glaciations: A Case Study of Ancient Gondwana
Ancient atmospheric CO2 concentrations played pivotal roles in shaping Earth’s prehistoric climates, particularly during periods of significant continental configurations. When carbon dioxide levels fell within the range of around 1,000 to 2,300 parts per million (ppm), they proved conducive to initiating glacial episodes across vast expanses of what we recognize today as the southern continents—once unified under the colossal supercontinent called Gondwana.
Gondwana—a term coined by Austrian geologist Eduard Suess, inspired by the Sanskrit phrase meaning "forest of the Gonds"—encompassed territories largely situated below the equator. These lands comprised modern-day Antarctica, South America, Africa, Madagascar, along with the Australian continent; notably, even portions of Arabia and the Indian subcontinent, both since migrated northward following tectonic shifts.
Approximately hundreds of millions years ago, Gondwana merged with another major land mass, Laurasia, culminating in the formation of the mega-continent Pangaea. However, this amalgamation remained transient, disintegrating roughly some hundred million years later. Post-separation, Gondwana drifted progressively polewards before eventually fracturing into its constituent pieces.
The fluctuating CO2 concentration throughout history has significantly influenced Earth's climate system, triggering alternating cycles of warmth and cold. During intervals where CO2 plummeted to relatively lower values compared to current standards, conditions favored extensive glaciation, prominently affecting areas encompassed by Gondwana. Understanding how past environments responded to varying degrees of atmospheric gases offers valuable insights into contemporary concerns regarding anthropogenic impacts on climate stability.

Ten million ( 10,000,000 ) is the natural number following 9,999,999 and preceding 10,000,001 .   In scientific notation , it is written as 107 .   In South Asia , it is known as the crore .

A diamond rush is a period of feverish migration of workers to an area that has had a discovery of diamonds . Major diamond rushes took place in the late 19th and early 20th centuries in South Africa and South-West Africa .

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

Lake Tauca is a former lake in the Altiplano of Bolivia . It is also known as Lake Pocoyu for its constituent lakes : Lake Poopó , Salar de Coipasa and Salar de Uyuni . The lake covered large parts of the southern Altiplano between the Eastern Cordillera and the Western Cordillera , covering an estimated 48,000 to of the basins of present-day Lake Poopó and the Salars of Uyuni , Coipasa and adjacent basins . Water levels varied , possibly reaching 3800 m in altitude . The lake was saline . The lake received water from Lake Titicaca , but whether this contributed most of Tauca 's water or only a small amount is controversial ; the quantity was sufficient to influence the local climate and depress the underlying terrain with its weight . Diatoms , plants and animals developed in the lake , sometimes forming reef knolls .   The duration of Lake Tauca 's existence is uncertain . Research in 2011 indicated that the rise in lake levels began 18,500 BP , peaking 16,000 and 14,500 years ago . About 14,200 years ago , lake levels dropped before rising again until 11,500 years ago . Some researchers postulate that the last phase of Lake Tauca may have continued until 8,500 BP . The drying of the lake , which may have occurred because of the Bølling-Allerød climate oscillation , left the salt deposits of Salar de Uyuni .   Lake Tauca is one of several ancient lakes which formed in the Altiplano . Other known lakes are Lake Escara , Ouki , Salinas , Lake Minchin , Inca Huasi and Sajsi , in addition to several water-level rises of Lake Titicaca . The identity of these lakes is controversial ; Sajsi is often considered part of Lake Tauca , and the lake is frequently divided into an earlier ( Ticaña ) and a later ( Coipasa ) phase .   The formation of Lake Tauca depended on a reduction in air temperature over the Altiplano and an increase in precipitation , which may have been caused by shifts in the Intertropical Convergence Zone ( ITCZ ) and increased easterly winds . It was originally supposed that glacial melting might have filled Lake Tauca , but the quantity of water would not have been sufficient to fill the whole lake . The lake was accompanied by glacial advance , noticeable at Cerro Azanaques and Tunupa . Elsewhere in South America , water levels and glaciers also expanded during the Lake Tauca phase .

The Latrobe Valley is an inland geographical district and urban area of the Gippsland region in the state of Victoria , Australia . The district lies east of the Melbourne and nestled between the Strzelecki Ranges to the south and the Baw Baw Ranges , part of the Great Dividing Range , to the north . Mount Baw Baw ( 1567 m ) is the highest peak to the north of the Latrobe Valley , due north of Moe . The highest peak to the south is Mt Tassie ( 740 m ) , south of Traralgon .   The area has four major centres , from west to east , Warragul , , Morwell and Traralgon , with minor centres including , , , and . The population of the Latrobe Valley is approximately 125,000 .   The valley draws its name from the Latrobe River which flows eastward , through the valley . According to Les Blake , in 1841 William Adams Brodribb , an early settler , named the river in honour of Charles La Trobe , Lieutenant Governor of the Port Phillip District . A. W. Reed also attributes Brodribb to naming the river in honour of La Trobe ; yet Reed claims that the river was discovered by Angus McMillan in 1840 who named the watercourse as Glengarry River .

Racism in Australia traces both historical and contemporary racist community attitudes , as well as political non-compliance and governmental negligence on United Nations human rights standard and incidents in Australia . Contemporary Australia is the product of multiple waves of immigration , predominantly from Great Britain and Ireland .   Laws forbid racial and other forms of discrimination and protect freedom of religion . Demographic analysis indicates a high level of inter-ethnic marriage : according to the Australian Census , a majority of Indigenous Australians partnered with non-indigenous Australians , and a majority of third-generation Australians of non-English-speaking background had partnered with persons of different ethnic origin ( the majority partnered with persons of Australian or Anglo-Celtic background , which constitutes the majority ethnic grouping in Australia ) . In 2009 , about 25.6 per cent of the estimated resident population of Australia comprised those born overseas .   Indigenous peoples of Australia , who had lived in Australia for at least 40,000 years before the arrival of British settlers in 1788 , were dispossessed from their land in 1788 by Britain , which claimed Eastern Australia as its own on the basis of the now discredited doctrine of terra nullius . Initially , indigenous Australians were in most states deprived of the rights of full citizenship of the new nation on grounds of their race and restrictive immigration laws were introduced to preference white European immigrants to Australia . Discriminatory laws against indigenous people and multiethnic immigration were dismantled in the early decades of the Post War period . A 1967 Referendum regarding Aboriginal rights was carried with over 90 % approval by the electorate . Legal reforms have re-established Aboriginal Land Rights under Australian law and in the early 21st century , indigenous Australians account for around 2.5 % of the population , owning outright around 20 % of all land . Intense focus on the impact of historical policies like the removal of mixed ethnicity Aboriginal children from their Aboriginal parent resulted in a bipartisan Parliamentary apology to Aborigines carried in 2008 . Aboriginal health indicators remain lower than other ethnic groups within Australia and again are the subject of political debate .   Policies of multiculturalism were pursued in the post-war period and first Eastern and Southern European , then Asian and African immigration increased significantly . Legislation including the Racial Discrimination Act 1975 , the Commonwealth Racial Hatred Act ( 1995 ) and the Human Rights and Equal Opportunity Commission Act ( 1986 ) outlaw racial discrimination in the public sphere in Australia . In recent decades , anti-immigration political parties like the One Nation Party have received extensive media coverage , but only marginal electoral support and successive governments have maintained large , multiethnic programs of immigration . As in other Western nations , tensions in the aftermath of events like the September 11 attacks and Bali Bombing by radical Islamists contributed to strained ethnic relations in some Australian communities .

Dart Moraine is an area of brown moraine , extending for 7 nmi south of Radok Lake and Pagodroma Gorge and west of Flagstone Bench , at the eastern end of the Aramis Range of the Prince Charles Mountains . It was photographed by Australian National Antarctic Research Expeditions ( ANARE ) in 1956 . This moraine was crossed many times in January -- February 1969 by J. Dart , radio officer with the ANARE party camped at Radok Lake on his way to the aircraft landing strip used to supply the camp .

The Diolkos ( Δίολκος , from the Greek διά , dia `` across '' and ὁλκός , holkos `` portage machine '' ) was a paved trackway near Corinth in Ancient Greece which enabled boats to be moved overland across the Isthmus of Corinth . The shortcut allowed ancient vessels to avoid the long and dangerous circumnavigation of the Peloponnese peninsula . The phrase `` as fast as a Corinthian '' , penned by the comic playwright Aristophanes , indicates that the trackway was common knowledge and had acquired a reputation for swiftness .   The main function of the Diolkos was the transfer of goods , although in times of war it also became a preferred means of speeding up naval campaigns . The 6 km to 8.5 km long roadway was a rudimentary form of railway , and operated from c. 600 BC until the middle of the 1st century AD . The scale on which the Diolkos combined the two principles of the railway and the overland transport of ships remained unique in antiquity .

Radiocarbon is a scientific journal devoted to the topic of radiocarbon dating . It was founded in 1959 as a supplement to the American Journal of Science , and is an important source of data and information about radiocarbon dating . It publishes many radiocarbon results , and since 1979 it has published the proceedings of the international conferences on radiocarbon dating .

In mathematics , Landau 's function g ( n ) , named after Edmund Landau , is defined for every natural number n to be the largest order of an element of the symmetric group Sn . Equivalently , g ( n ) is the largest least common multiple ( lcm ) of any partition of n , or the maximum number of times a permutation of n elements can be recursively applied to itself before it returns to its starting sequence .   For instance , 5 = 2 + 3 and lcm ( 2,3 ) = 6 . No other partition of 5 yields a bigger lcm , so g ( 5 ) = 6 . An element of order 6 in the group S5 can be written in cycle notation as ( 1 2 ) ( 3 4 5 ) .   The integer sequence g ( 0 ) = 1 , g ( 1 ) = 1 , g ( 2 ) = 2 , g ( 3 ) = 3 , g ( 4 ) = 4 , g ( 5 ) = 6 , g ( 6 ) = 6 , g ( 7 ) = 12 , g ( 8 ) = 15 , ... is named after Edmund Landau , who proved in 1902 that   ( where ln denotes the natural logarithm ) . In other words , .   The statement that   for all sufficiently large n , where Li − 1 denotes the inverse of the logarithmic integral function , is equivalent to the Riemann hypothesis .   It can be shown that   and indeed


Question: Indeed, carbon dioxide concentrations within the range of approximately 1,000 to 2,300 parts per million were sufficiently reduced to facilitate ice sheet formation across the ancient landmass known as Gondwana.

 CO₂ Levels Influencing Glaciation Patterns
Throughout history, fluctuations in atmospheric carbon dioxide levels significantly impacted Earth’s glacial cycles. During periods where concentrations remained around 1,000 to 2,300 parts per million (ppm), conditions favored extensive glaciations across major portions of what was then known as Gondwana - a vast ancient supercontinent encompassing current-day South America, Africa, Antarctica, Australia, and the Indian subcontinent. These lower-than-today CO₂ values contributed to cooler climates conducive to ice sheet expansion particularly within high latitude regions surrounding Antarctic territories. Understanding how varying degrees of greenhouse gases correlate with historical ice ages provides crucial insights into contemporary concerns regarding global warming trends triggered predominantly through anthropogenic sources.
Note: I've maintained both content complexity & length while ensuring no alteration occurs concerning original argumentative stance presented; namely highlighting connection b/w specific ranges of Carbon Dioxide concentration & initiation/propagation phases associated w/glacial epochs affecting former mega-landmass configurations akin to Pangea/Gondwanaland etcetera...

The Denmark Hill Insect Bed is a Triassic fossil locality in the Denmark Hill Conservation Park of Ipswich , Queensland , Australia . It belongs to the Blackstone Formation ( Ipswich Coal Measures Group ) dated to the Carnian age ( 228.0 - 216.5 million years ago ) . Its coordinates are . Its paleogeographic coordinates are .   The fossiliferous layer is located in between the Bluff coal seam and the Aberdare coal seam . It is 15 cm thick and is composed greenish grey to brownish grey arenaceous shale . The existence of coal seams above and below the layer indicates that it may have once been a lake ( lacustrine environment ) .   The site is noted as a source of well-preserved insect fossils .

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

The Deseadan age is a period of geologic time ( 29.0 -- 21.0 Ma ) within the Oligocene epoch of the Paleogene used more specifically with South American Land Mammal Ages . It follows the Tinguirirican and precedes the Colhuehuapian age .

Land councils , also known as land and sea councils , are Australian community organisations , generally organised by region , that are commonly formed to represent the Indigenous Australians who occupied their particular region before the arrival of European settlers . They have historically advocated for recognition of traditional land rights , and also for the rights of Indigenous people in other areas such as equal wages and adequate housing . Some states , such as the Northern Territory , have laws that provide for the existence of land councils and allocate them responsibilities for representing Aboriginal people in various matters . Other states do not have such laws , or have laws that provide for the existence of Aboriginal organisations that do not call themselves land councils to provide functions similar to those provided by land councils in some states . An example of this is in Victoria , where there are laws providing for organisations called ` Registered Aboriginal Parties ' , which provide functions in relation to Aboriginal people similar to those provided by land councils in , say , the Northern Territory .   Most land councils provide representation and organisation in relation to native title matters for Indigenous Australians , and receive funding from the Australian Commonwealth Government to do this work . However , Commonwealth native title laws do not require such representation and organisation to be provided by land councils , and there are many other sorts of organisations that also provide these sorts of services .   Most land councils were formed since the late 1970s to gain native title and other forms of Aboriginal land rights .   Some land councils can be governed by other , larger councils , which federate multiple local land councils for representation at the state and federal level .

Refrigeration is a process of moving heat from one location to another in controlled conditions . The work of heat transport is traditionally driven by mechanical work , but can also be driven by heat , magnetism , electricity , laser , or other means . Refrigeration has many applications , including , but not limited to : household refrigerators , industrial freezers , cryogenics , and air conditioning . Heat pumps may use the heat output of the refrigeration process , and also may be designed to be reversible , but are otherwise similar to air conditioning units .   Refrigeration has had a large impact on industry , lifestyle , agriculture and settlement patterns . The idea of preserving food dates back to at least the ancient Roman and Chinese empires . However , mechanical refrigeration technology has rapidly evolved in the last century , from ice harvesting to temperature-controlled rail cars . The introduction of refrigerated rail cars contributed to the westward expansion of the United States , allowing settlement in areas that were not on main transport channels such as rivers , harbors , or valley trails . Settlements were also developing in infertile parts of the country , filled with newly discovered natural resources . These new settlement patterns sparked the building of large cities which are able to thrive in areas that were otherwise thought to be inhospitable , such as Houston , Texas and Las Vegas , Nevada . In most developed countries , cities are heavily dependent upon refrigeration in supermarkets , in order to obtain their food for daily consumption . The increase in food sources has led to a larger concentration of agricultural sales coming from a smaller percentage of existing farms . Farms today have a much larger output per person in comparison to the late 1800s . This has resulted in new food sources available to entire populations , which has had a large impact on the nutrition of society .

Lands administrative divisions of Australia are the parts of Australia which are divided into the cadastral units of counties , parishes , hundreds , and other divisions for the purposes of land ownership . Many property titles in Australia are listed as being in the parish and county .   The whole of the eastern states of Queensland , New South Wales , Victoria and Tasmania were divided into counties and parishes in the 19th century , although the Tasmanian counties were renamed land districts in the twentieth century . Parts of South Australia ( south-east ) and Western Australia ( south-west ) were similarly divided into counties , and there were also five counties in a small part of the Northern Territory . However South Australia has subdivisions of hundreds instead of parishes , along with the Northern Territory , which was part of South Australia when the hundreds were proclaimed . There were also formerly hundreds in Tasmania . There have been at least 600 counties , 544 hundreds and at least 15,692 parishes in Australia , but there are none of these units for most of the sparsely inhabited central and western parts of the country .   Counties in Australia have no administrative or political function , unlike those in England , the United States or Canada . Australia instead uses local government areas , including shires , districts , councils and municipalities according to the state , as the second level subdivision .   Some other states were also divided into land divisions and land districts ; in the nineteenth century land districts sometimes served as the region name for parts of the state where counties had not been proclaimed yet . Below these are groups of land parcels known as deposited plans , registered plans or title plans ( depending on the state ) . Queensland has registered plans ; New South Wales and Western Australia have deposited plans ; while Victoria has certified plans . Land can be identified using the number of this plan of subdivision held with the lands department , rather than with a named unit such as a parish ( or both can be used ) ; it is becoming increasingly common to use only the plan number . Within these are individual land parcels such as lots ; in total there are estimated to be about 10.2 million of these in Australia . The various cadastral units appear on certificates of title , which are given volume and folio numbers ; these numbers by themselves are sometimes used to identify land parcels , or in combination with the other units . Detailed maps of these divisions have been required since the introduction of the Torrens title system of a central register of land holdings in South Australia in 1858 , which spread to the other colonies . While cadastral data since the 1980s has been digitalised , there remain many old maps showing these divisions held in collections of Australian libraries such as the National Library of Australia , as well as in state libraries .

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