The Earth's atmosphere is a key factor in sustaining the ecosystem. The thin layer of gases that envelops the Earth is held in place by gravity. Air is mostly nitrogen, oxygen, water vapor, with much smaller amounts of carbon dioxide, argon, etc. The atmospheric pressure declines steadily with altitude. The ozone layer plays an important role in depleting the amount of ultraviolet (UV) radiation that reaches the surface. As DNA is readily damaged by UV light, this serves to protect life at the surface. The atmosphere also retains heat during the night, thereby reducing the daily temperature extremes.

Question: How is the layer of gas enveloping Earth stay where it is?
Answer: gravity
The biosphere is the part of Earth's outer shell—including land, surface rocks, water, air and the atmosphere—within which life occurs, and which biotic processes in turn alter or transform. From the broadest geophysiological point of view, the biosphere is the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere (rocks), hydrosphere (water), and atmosphere (air). The entire Earth contains over 75 billion tons (150 trillion pounds or about 6.8×1013 kilograms) of biomass (life), which lives within various environments within the biosphere.Over nine-tenths of the total biomass on Earth is plant life, on which animal life depends very heavily for its existence. More than 2 million species of plant and animal life have been identified to date, and estimates of the actual number of existing species range from several million to well over 50 million. The number of individual species of life is constantly in some degree of flux, with new species appearing and others ceasing to exist on a continual basis. The total number of species is in rapid decline.

Question: What makes up the biosphere?
Answer: land, surface rocks, water, air and the atmosphere

Question: what makes up the biosphere?
Answer: the global ecological system integrating all living beings and their relationships, including their interaction with the elements of the lithosphere (rocks), hydrosphere (water), and atmosphere (air)
Sarajevo has been home to many different religions for centuries, giving the city a range of diverse cultures. In the time of Ottoman occupation of Bosnia, Muslims, Serbian Orthodox, Roman Catholics, and Sephardi Jews all shared the city while maintaining distinctive identities. They were joined during the brief occupation by Austria-Hungary by a smaller number of Germans, Hungarians, Slovaks, Czechs and Ashkenazi Jews. By 1909, about 50% of the city's inhabitants were Muslim, 25% were Catholic, 15% were Orthodox, and 10% were Jewish.Historically, Sarajevo has been home to several prominent Bosnian poets, scholars, philosophers, and writers. To list only a very few; Nobel Prize-winner Vladimir Prelog is from the city, as are the writer Zlatko Topčić, and the poet Abdulah Sidran. Nobel Prize-winner Ivo Andrić attended high school in Sarajevo for two years. Academy Award-winning director Danis Tanović live in the city. Sarajevo is also the home of the East West Theatre Company, the only independent theater company in Bosnia and Herzegovina.

Question: There was religious freedom while who occupied Bosnia?
Answer: Ottoman

Question: What is Sarajevo known for?
Answer: many different religions
Sarajevo is near the geometric center of the triangular-shaped Bosnia-Herzegovina and within the historical region of Bosnia proper. It is situated 518 meters (1,699 ft) above sea level and lies in the Sarajevo valley, in the middle of the Dinaric Alps. The valley itself once formed a vast expanse of greenery, but gave way to urban expansion and development in the post-World War II era. The city is surrounded by heavily forested hills and five major mountains. The highest of the surrounding peaks is Treskavica at 2,088 meters (6,850 ft), then Bjelašnica mountain at 2,067 meters (6,781 ft), Jahorina at 1,913 meters (6,276 ft), Trebević at 1,627 meters (5,338 ft), with 1,502 meters (4,928 ft) Igman being the shortest. The last four are also known as the Olympic Mountains of Sarajevo (see also 1984 Winter Olympics). The city itself has its fair share of hilly terrain, as evidenced by the many steeply inclined streets and residences seemingly perched on the hillsides.

Question: What type of development occurred during the post war era?
Answer: urban expansion

Question: What types of geological structure are Treskavica and Jahorina??
Answer: heavily forested hills and five major mountains
The Miljacka river is one of the city's chief geographic features. It flows through the city from east through the center of Sarajevo to west part of city where eventually meets up with the Bosna river. Miljacka river is "The Sarajevo River", with its source (Vrelo Miljacke) 2 kilometres (1.2 miles) south of the town of Pale at the foothills of Mount Jahorina, several kilometers to the east of Sarajevo center. The Bosna's source, Vrelo Bosne near Ilidža (west Sarajevo), is another notable natural landmark and a popular destination for Sarajevans and other tourists. Several smaller rivers and streams such as Koševski Potok also run through the city and its vicinity.

Question: Which river is considered "the Sarajevo River"?
Answer: Miljacka

Question: In which direction does the river flow?
Answer: from east through the center of Sarajevo to west
The last official Yugoslav census took place 1991 and recorded 527,049 people living in the city of Sarajevo (ten municipalities). In the settlement of Sarajevo proper, there were 416,497 inhabitants. The war displaced hundreds of thousands of people, a large majority of whom have not returned.

Question: In what year did the last official Yugoslave census take place?
Answer: 1991

Question: how many people lived in Sarajevo?
Answer: 416,497 inhabitants
The mainstay of current treatment is antipsychotic medication combined with mood stabilizer medication or antidepressant medication, or both. There is growing concern by some researchers that antidepressants may increase psychosis, mania, and long-term mood episode cycling in the disorder. When there is risk to self or others, usually early in treatment, hospitalization may be necessary. Psychiatric rehabilitation, psychotherapy, and vocational rehabilitation are very important for recovery of higher psychosocial function. As a group, people with schizoaffective disorder that were diagnosed using DSM-IV and ICD-10 criteria (which have since been updated) have a better outcome than people with schizophrenia, but have variable individual psychosocial functional outcomes compared to people with mood disorders, from worse to the same. Outcomes for people with DSM-5 diagnosed schizoaffective disorder depend on data from prospective cohort studies, which have not been completed yet. The DSM-5 diagnosis was updated because DSM-IV criteria resulted in overuse of the diagnosis; that is, DSM-IV criteria led to many patients being misdiagnosed with the disorder. DSM-IV prevalence estimates were less than one percent of the population, in the range of 0.5-0.8 percent; newer DSM-5 prevalence estimates are not yet available.

Question: what can be combined with antipsychotic medication?
Answer: mood stabilizer medication or antidepressant medication, or both
As of the census of 2000, there were 735 people, 284 households, and 241 families residing in the village. The population density was 92.1 people per square mile (35.6/km2). Of the 735 people, 728 of them are white. There were 317 housing units at an average density of 39.7 per square mile (15.3/km2). The racial makeup of the village was 99.05% White, 0.14% African American, 0.68% Asian, and 0.14% from two or more races. Hispanic or Latino of any race were 0.54% of the population. 17.4% were of English, 17.1% German, 11.0% Irish, 9.0% Italian, 5.7% American and 5.6% Russian ancestry according to Census 2000.

Question: How many housing unit are in the village?
Answer: 317
Racism was the main target of Du Bois's polemics, and he strongly protested against lynching, Jim Crow laws, and discrimination in education and employment. His cause included people of color everywhere, particularly Africans and Asians in colonies. He was a proponent of Pan-Africanism and helped organize several Pan-African Congresses to fight for the independence of African colonies from European powers. Du Bois made several trips to Europe, Africa and Asia. After World War I, he surveyed the experiences of American black soldiers in France and documented widespread prejudice in the United States military.

Question: What political bodies did Du Bois help organize?
Answer: Pan-African Congresses

Question: Where was widespread prejudice documented?
Answer: United States military
Relying on money donated by neighbors, Du Bois attended Fisk University, a historically black college in Nashville, Tennessee, from 1885 to 1888. His travel to and residency in the South was Du Bois's first experience with Southern racism, which at the time encompassed Jim Crow laws, bigotry, suppression of black voting, and lynchings; the lattermost reached a peak in the next decade. After receiving a bachelor's degree from Fisk, he attended Harvard College (which did not accept course credits from Fisk) from 1888 to 1890, where he was strongly influenced by his professor William James, prominent in American philosophy. Du Bois paid his way through three years at Harvard with money from summer jobs, an inheritance, scholarships, and loans from friends. In 1890, Harvard awarded Du Bois his second bachelor's degree, cum laude, in history. In 1891, Du Bois received a scholarship to attend the sociology graduate school at Harvard.In 1892, Du Bois received a fellowship from the John F. Slater Fund for the Education of Freedmen to attend the University of Berlin for graduate work. While a student in Berlin, he traveled extensively throughout Europe. He came of age intellectually in the German capital while studying with some of that nation's most prominent social scientists, including Gustav von Schmoller, Adolph Wagner, and Heinrich von Treitschke. He wrote about his time in Germany: "I found myself on the outside of the American world, looking in. With me were white folk—students, acquaintances, teachers—who viewed the scene with me. They did not always pause to regard me as a curiosity, or something sub-human; I was just a man of the somewhat privileged student rank, with whom they were glad to meet and talk over the world; particularly, the part of the world whence I came." After returning from Europe, Du Bois completed his graduate studies; in 1895 he was the first African American to earn a Ph.D. from Harvard University.

Question: Which prominent  social scientists did Du Bois work with?
Answer: Gustav von Schmoller, Adolph Wagner, and Heinrich von Treitschke
The major advance in integration came in the 17th century with the independent discovery of the fundamental theorem of calculus by Newton and Leibniz. The theorem demonstrates a connection between integration and differentiation. This connection, combined with the comparative ease of differentiation, can be exploited to calculate integrals. In particular, the fundamental theorem of calculus allows one to solve a much broader class of problems. Equal in importance is the comprehensive mathematical framework that both Newton and Leibniz developed. Given the name infinitesimal calculus, it allowed for precise analysis of functions within continuous domains. This framework eventually became modern calculus, whose notation for integrals is drawn directly from the work of Leibniz.

Question: What connection does the theorem of calculas created by Newton show?
Answer: a connection between integration and differentiation
There are many ways of formally defining an integral, not all of which are equivalent. The differences exist mostly to deal with differing special cases which may not be integrable under other definitions, but also occasionally for pedagogical reasons. The most commonly used definitions of integral are Riemann integrals and Lebesgue integrals.

Question: What does the difference in defining an integral address?
Answer: to deal with differing special cases
Ice giants have distinctly different interior compositions from gas giants. The Solar System's ice giants, Uranus and Neptune, have a hydrogen-rich atmosphere that extends from the cloud tops down to about 80% (Uranus) or 85% (Neptune) of their radius. Below this, they are predominantly "icy", i.e. consist mostly of water, methane, and ammonia. There is also some rock and gas, but various proportions of ice–rock–gas could mimic pure ice, so that the exact proportions are unknown.Uranus and Neptune have very hazy atmospheric layers with small amounts of methane, giving them aquamarine colors; light blue and ultramarine respectively. Both have magnetic fields that are sharply inclined to their axes of rotation.

Question: What do Uranus and Neptune have in common?
Answer: magnetic fields that are sharply inclined to their axes of rotation
The term gas giant was coined in 1952 by the science fiction writer James Blish and was originally used to refer to all giant planets. Arguably it is something of a misnomer, because throughout most of the volume of these planets the pressure is so high that matter is not in gaseous form. Other than the upper layers of the atmosphere and solids in the core, all matter is above the critical point, where there is no distinction between liquids and gases. Fluid planet would be a more accurate term. Jupiter also has metallic hydrogen near its center, but much of its volume is hydrogen, helium, and traces of other gases above their critical points. The observable atmospheres of all these planets (at less than unit optical depth) are quite thin compared to their radii, only extending perhaps one percent of the way to the center. Thus the observable portions are gaseous (in contrast to Mars and Earth, which have gaseous atmospheres through which the crust can be seen).

Question: How are Jupiter's atmospheres?
Answer: quite thin compared to their radii
Parajanov served four years out of his five-year sentence, and later credited his early release to the efforts of the French Surrealist poet and novelist Louis Aragon, the Russian poet Elsa Triolet (Aragon's wife), and the American writer John Updike. His early release was authorized by Leonid Brezhnev, General Secretary of the Communist Party of the Soviet Union, presumably as a consequence of Brezhnev's chance meeting with Aragon and Triolet at the Bolshoi Theatre in Moscow. When asked by Brezhnev if he could be of any assistance, Aragon requested the release of Parajanov, which was effected by December 1977.While he was incarcerated, Parajanov produced a large number of miniature doll-like sculptures (some of which were lost) and some 800 drawings and collages, many of which were later displayed in Yerevan, where the Sergei Parajanov Museum is now permanently located. (The museum, opened in 1991, a year after Parajanov’s death, hosts more than 200 works as well as furnishings from his home in Tbilisi.) His efforts in the camp were repeatedly compromised by prison guards, who deprived him of materials and called him mad, their cruelty only subsiding after a statement from Moscow admitted that "the director is very talented."After his return from prison to Tbilisi, the close watch of Soviet censors prevented Parajanov from continuing his cinematic pursuits and steered him towards the artistic outlets he had nurtured during his time in prison. He crafted extraordinarily intricate collages, created a large collection of abstract drawings and pursued numerous other avenues of non-cinematic art, sewing more dolls and some whimsical suits.

Question: What types of objects did he produce through sewing?
Answer: dolls and some whimsical suits
Parajanov then attempted to complete his final project. He died of cancer in Yerevan, Armenia, on July 20, 1990, aged 66, leaving this final work, The Confession, unfinished. It survives in its original negative as Parajanov: The Last Spring (film), assembled by his close friend Mikhail Vartanov in 1992. Federico Fellini, Tonino Guerra, Francesco Rosi, Alberto Moravia, Giulietta Masina, Marcello Mastroianni and Bernardo Bertolucci were among those who publicly mourned his death. They sent a telegram to Russia with the following statement: "The world of cinema has lost a magician".

Question: How old was Parajanov when he died?
Answer: 66
At first, the relationship between Cope and Marsh was amicable. They met in Berlin in 1864 and spent several days together. They even named species after each other. Over time their relations soured, due in part to their strong personalities. Cope was known to be pugnacious and possessed a quick temper; Marsh was slower, more methodical, and introverted. Both were quarrelsome and distrustful. Their differences also extended into the scientific realm, as Cope was a firm supporter of Neo-Lamarckism while Marsh supported Charles Darwin's theory of evolution by natural selection. Even at the best of times, both men were inclined to look down on each other subtly. As one observer put it, "The patrician Edward may have considered Marsh not quite a gentleman. The academic Othniel probably regarded Cope as not quite a professional."Cope and Marsh came from very different backgrounds. Cope was born into a wealthy and influential Quaker family based in Philadelphia. Although his father wanted his son to work as a farmer, Cope distinguished himself as a naturalist. In 1864, already a member of the Academy of Natural Sciences, Cope became a professor of zoology at Haverford College and joined Ferdinand Hayden on his expeditions west. In contrast, Marsh would have grown up poor, the son of a struggling family in Lockport, New York, had it not been for the benefaction of his uncle, philanthropist George Peabody. Marsh persuaded his uncle to build the Peabody Museum of Natural History, placing Marsh as head of the museum. Combined with the inheritance he received from Peabody upon his death in 1869, Marsh was financially comfortable (although, partly because of Peabody's stern views on marriage, Marsh would remain a lifelong bachelor).

Question: How did Marsh compare to Cope?
Answer: slower, more methodical, and introverted
Judging by pure numbers, Marsh "won" the Bone Wars. Both scientists made finds of immense scientific value, but while Cope discovered a total of 56 new dinosaur species, Marsh discovered 80. In the later stages of the Bone Wars, Marsh simply had more men and money at his disposal than Cope. Cope also had a much broader set of paleontological interests, while Marsh almost exclusively pursued fossilized reptiles and mammals.Several of Cope's and Marsh's discoveries are among the most well-known of dinosaurs, encompassing species of Triceratops, Allosaurus, Diplodocus, Stegosaurus, Camarasaurus and Coelophysis. Their cumulative discoveries defined the then-nascent field of paleontology; before Cope's and Marsh's discoveries, there were only nine named species of dinosaur in North America. Some of their ideas—such as Marsh's argument that birds are descended from dinosaurs—have been upheld; while others are viewed as having little to no scientific merit. The Bone Wars also led to the discovery of the first complete skeletons, and the rise in popularity of dinosaurs with the public. As paleontologist Robert Bakker stated, "The dinosaurs that came from [Como Bluff] not only filled museums, they filled magazine articles, textbooks, they filled people's minds."Despite their advances, the Bone Wars also had a negative effect not only on the two scientists but also on their peers and the entire field. The public animosity between Cope and Marsh harmed the reputation of American paleontology in Europe for decades. Furthermore, the reported use of dynamite and sabotage by employees of both men may have destroyed or buried hundreds of potentially critical fossil remains. Joseph Leidy abandoned his more methodical excavations in the West, finding he could not keep up with Cope's and Marsh's reckless searching for bones. Leidy also grew tired of the constant squabbling between the two men, with the result that his withdrawal from the field marginalized his own legacy; after his death, Osborn found not a single mention of the man in either of the rivals' works. In their haste to outdo each other, Cope and Marsh haphazardly assembled the bones of their own discoveries. Their descriptions of new species, based on their reconstructions, led to confusion and misconceptions that lasted for decades after their deaths.A 2007–2008 excavation of several of Cope's and Marsh's sites suggest that the damage perpetrated by the two paleontologists was less than what has been reported. Using Lakes' field paintings, researchers from the Morrison Natural History Museum discovered that Lakes had not actually dynamited the most productive quarries in Colorado; rather, Lakes had just filled in the site. Museum director Matthew Mossbrucker theorized that Lakes propagated the lie "because he didn't want the competition up at the quarry—playing mind games with Cope's gang."

Question: What were the names of the two people that had friction between them?
Answer: Cope and Marsh
A data logger (also datalogger or data recorder) is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer). They generally are small, battery powered, portable, and equipped with a microprocessor, internal memory for data storage, and sensors. Some data loggers interface with a personal computer, and use software to activate the data logger and view and analyze the collected data, while others have a local interface device (keypad, LCD) and can be used as a stand-alone device.

Question: What is the size of the data logger?
Answer: small
Data loggers are implicitly stand-alone devices, while typical data acquisition system must remain tethered to a computer to acquire data. This stand-alone aspect of data loggers implies on-board memory that is used to store acquired data. Sometimes this memory is very large to accommodate many days, or even months, of unattended recording.  This memory may be battery-backed static random access memory, flash memory or EEPROM.  Earlier data loggers used magnetic tape, punched paper tape, or directly viewable records such as "strip chart recorders".

Question: what must data acquisition systems stay connected to?
Answer: a computer
Several protocols have been standardised including a smart protocol, SDI-12, that allows some instrumentation to be connected to a variety of data loggers. The use of this standard has not gained much acceptance outside the environmental industry. SDI-12 also supports multi drop instruments. Some datalogging companies are also now supporting the MODBUS standard. This has been used traditionally in the industrial control area, and there are many industrial instruments which support this communication standard. Another multi drop protocol which is now starting to become more widely used is based upon CAN Bus (ISO 11898). Some data loggers use a flexible scripting environment to adapt themselves to various non-standard protocols.

Question: What industry mainly uses SDI-12?
Answer: environmental industry
