Most light bulbs have either clear or coated glass. The coated glass bulbs have a white powdery substance on the inside called kaolin. Kaolin, or kaolinite, is a white, chalky clay in a very fine powder form, that is blown in and electrostatically deposited on the interior of the bulb. It diffuses the light emitted from the filament, producing a more gentle and evenly distributed light. Manufacturers may add pigments to the kaolin to adjust the characteristics of the final light emitted from the bulb. Kaolin diffused bulbs are used extensively in interior lighting because of their comparatively gentle light. Other kinds of colored bulbs are also made, including the various colors used for "party bulbs", Christmas tree lights and other decorative lighting. These are created by coloring the glass with a dopant; which is often a metal like cobalt (blue) or chromium (green). Neodymium-containing glass is sometimes used to provide a more natural-appearing light.

Question: How are Christmas colored light bulbs created?
Answer: by coloring the glass with a dopant.

At the homestead, Bell set up his own workshop in the converted carriage house near to what he called his "dreaming place", a large hollow nestled in trees at the back of the property above the river. Despite his frail condition upon arriving in Canada, Bell found the climate and environs to his liking, and rapidly improved.[N 10] He continued his interest in the study of the human voice and when he discovered the Six Nations Reserve across the river at Onondaga, he learned the Mohawk language and translated its unwritten vocabulary into Visible Speech symbols. For his work, Bell was awarded the title of Honorary Chief and participated in a ceremony where he donned a Mohawk headdress and danced traditional dances.[N 11]

Before the attack on Pearl Harbor, the 800,000-member America First Committee vehemently opposed any American intervention in the European conflict, even as America sold military aid to Britain and the Soviet Union through the Lend-Lease program. Opposition to war in the U.S. vanished after the attack. On 8 December, the United States, the United Kingdom, Canada, and the Netherlands declared war on Japan, followed by China and Australia the next day. Four days after Pearl Harbor, Nazi Germany and Fascist Italy declared war on the United States, drawing the country into a two-theater war. This is widely agreed to be a grand strategic blunder, as it abrogated the benefit Germany gained by Japan's distraction of the U.S. (predicted months before in a memo by Commander Arthur McCollum)[nb 12] and the reduction in aid to Britain, which both Congress and Hitler had managed to avoid during over a year of mutual provocation, which would otherwise have resulted.

In January, Japan invaded Burma, the Dutch East Indies, New Guinea, the Solomon Islands and captured Manila, Kuala Lumpur and Rabaul. After being driven out of Malaya, Allied forces in Singapore attempted to resist the Japanese during the Battle of Singapore but surrendered to the Japanese on 15 February 1942; about 130,000 Indian, British, Australian and Dutch personnel became prisoners of war. The pace of conquest was rapid: Bali and Timor also fell in February. The rapid collapse of Allied resistance had left the "ABDA area" split in two. Wavell resigned from ABDACOM on 25 February, handing control of the ABDA Area to local commanders and returning to the post of Commander-in-Chief, India.

Question: After Wavell resigned from ABDACOM, What post did he return to?
Answer: Commander-in-Chief, India.

Many assembled PCBs are static sensitive, and therefore must be placed in antistatic bags during transport. When handling these boards, the user must be grounded (earthed). Improper handling techniques might transmit an accumulated static charge through the board, damaging or destroying components. Even bare boards are sometimes static sensitive. Traces have become so fine that it's quite possible to blow an etch off the board (or change its characteristics) with a static charge. This is especially true on non-traditional PCBs such as MCMs and microwave PCBs.

---

Question: What force can easily change or even completely destroy an etch on a PCB?
Answer: static charge.

Partly because of low sanitation coverage about 17,000 children die each year because of diarrhoea. Another challenge is low cost recovery due to water tariffs that are among the lowest in the world. This in turn requires government subsidies even for operating costs, a situation that has been aggravated by salary increases without tariff increases after the Arab Spring. Poor operation of facilities, such as water and wastewater treatment plants, as well as limited government accountability and transparency, are also issues.

Question: Due to low waer tariffs, what is required to maintain water treatment operation?
Answer: government subsidies.

Only service dress is suitable for CAF members to wear on any occasion, barring "dirty work" or combat. With gloves, swords, and medals (No. 1 or 1A), it is suitable for ceremonial occasions and "dressed down" (No. 3 or lower), it is suitable for daily wear. Generally, after the elimination of base dress (although still defined for the Air Force uniform), operational dress is now the daily uniform worn by most members of the CF, unless service dress is prescribed (such as at the NDHQ, on parades, at public events, etc.). Approved parkas are authorized for winter wear in cold climates and a light casual jacket is also authorized for cooler days. The navy, most army, and some other units have, for very specific occasions, a ceremonial/regimental full dress, such as the naval "high-collar" white uniform, kilted Highland, Scottish, and Irish regiments, and the scarlet uniforms of the Royal Military Colleges.

Finally, an introduced species may unintentionally injure a species that depends on the species it replaces. In Belgium, Prunus spinosa from Eastern Europe leafs much sooner than its West European counterparts, disrupting the feeding habits of the Thecla betulae butterfly (which feeds on the leaves). Introducing new species often leaves endemic and other local species unable to compete with the exotic species and unable to survive. The exotic organisms may be predators, parasites, or may simply outcompete indigenous species for nutrients, water and light.

In March 2001, 40 multi-national pharmaceutical companies brought litigation against South Africa for its Medicines Act, which allowed the generic production of antiretroviral drugs (ARVs) for treating HIV, despite the fact that these drugs were on-patent. HIV was and is an epidemic in South Africa, and ARVs at the time cost between 10,000 and 15,000 USD per patient per year. This was unaffordable for most South African citizens, and so the South African government committed to providing ARVs at prices closer to what people could afford. To do so, they would need to ignore the patents on drugs and produce generics within the country (using a compulsory license), or import them from abroad. After international protest in favour of public health rights (including the collection of 250,000 signatures by MSF), the governments of several developed countries (including The Netherlands, Germany, France, and later the US) backed the South African government, and the case was dropped in April of that year.

Question: Who backed the South African government which caused the case to be dropped?
Answer: The Netherlands, Germany, France, and later the US.

British night air defences were in a poor state. Few anti-aircraft guns had fire-control systems, and the underpowered searchlights were usually ineffective against aircraft at altitudes above 12,000 ft (3,700 m). In July 1940, only 1,200 heavy and 549 light guns were deployed in the whole of Britain. Of the "heavies", some 200 were of the obsolescent 3 in (76 mm) type; the remainder were the effective 4.5 in (110 mm) and 3.7 in (94 mm) guns, with a theoretical "ceiling"' of over 30,000 ft (9,100 m) but a practical limit of 25,000 ft (7,600 m) because the predictor in use could not accept greater heights. The light guns, about half of which were of the excellent Bofors 40 mm, dealt with aircraft only up to 6,000 ft (1,800 m). Although the use of the guns improved civilian morale, with the knowledge the German bomber crews were facing the barrage, it is now believed that the anti-aircraft guns achieved little and in fact the falling shell fragments caused more British casualties on the ground.

Question: British night air defenses were effective to what height?
Answer: 12,000 ft (3,700 m).

The Liberal Party's organisation is dominated by the six state divisions, reflecting the party's original commitment to a federalised system of government (a commitment which was strongly maintained by all Liberal governments until 1983, but was to a large extent abandoned by the Howard Government, which showed strong centralising tendencies). Menzies deliberately created a weak national party machine and strong state divisions. Party policy is made almost entirely by the parliamentary parties, not by the party's rank-and-file members, although Liberal party members do have a degree of influence over party policy.

The vicereine Germaine of Foix brutally repressed the uprising and its leaders, and this accelerated the authoritarian centralisation of the government of Charles I. Queen Germaine favoured harsh treatment of the agermanats. She is thought to have signed the death warrants of 100 former rebels personally, and sources indicate that as many as 800 executions may have occurred. The agermanats are comparable to the comuneros of neighbouring Castile, who fought a similar revolt against Charles from 1520–1522.

South America became linked to North America through the Isthmus of Panama during the Pliocene, bringing a nearly complete end to South America's distinctive marsupial faunas. The formation of the Isthmus had major consequences on global temperatures, since warm equatorial ocean currents were cut off and an Atlantic cooling cycle began, with cold Arctic and Antarctic waters dropping temperatures in the now-isolated Atlantic Ocean. Africa's collision with Europe formed the Mediterranean Sea, cutting off the remnants of the Tethys Ocean. Sea level changes exposed the land-bridge between Alaska and Asia. Near the end of the Pliocene, about 2.58 million years ago (the start of the Quaternary Period), the current ice age began. The polar regions have since undergone repeated cycles of glaciation and thaw, repeating every 40,000–100,000 years.

Question: What period came after the Pliocene?
Answer: the Quaternary Period.

Smaller boats and ships typically have machine-guns or fast cannons, which can often be deadly to low-flying aircraft if linked to a radar-directed fire-control system radar-controlled cannon for point defence. Some vessels like Aegis cruisers are as much a threat to aircraft as any land-based air defence system. In general, naval vessels should be treated with respect by aircraft, however the reverse is equally true. Carrier battle groups are especially well defended, as not only do they typically consist of many vessels with heavy air defence armament but they are also able to launch fighter jets for combat air patrol overhead to intercept incoming airborne threats.

Question: What type of ships are particularly well defended?
Answer: Carrier battle groups.

The Basic Law of the Federal Republic of Germany, the federal constitution, stipulates that the structure of each Federal State's government must "conform to the principles of republican, democratic, and social government, based on the rule of law" (Article 28). Most of the states are governed by a cabinet led by a Ministerpräsident (Minister-President), together with a unicameral legislative body known as the Landtag (State Diet). The states are parliamentary republics and the relationship between their legislative and executive branches mirrors that of the federal system: the legislatures are popularly elected for four or five years (depending on the state), and the Minister-President is then chosen by a majority vote among the Landtag's members. The Minister-President appoints a cabinet to run the state's agencies and to carry out the executive duties of the state's government.

The first union was built on campus in 1926 as a campus community center. The unions are still the "living rooms" of campus today and include three locations – the Kansas Union and Burge Union at the Lawrence Campus and Jayhawk Central at the Edwards Campus. The KU Memorial Unions Corporation manages the KU Bookstore (with seven locations). The KU Bookstore is the official bookstore of KU. The Corporation also includes KU Dining Services, with more than 20 campus locations, including The Market (inside the Kansas Union) and The Underground (located in Wescoe Hall). The KU Bookstore and KU Dining Services are not-for-profit, with proceeds going back to support student programs, such as Student Union Activities.

The KU men's basketball team has fielded a team every year since 1898. The Jayhawks are a perennial national contender currently coached by Bill Self. The team has won five national titles, including three NCAA tournament championships in 1952, 1988, and 2008. The basketball program is currently the second winningest program in college basketball history with an overall record of 2,070–806 through the 2011–12 season. The team plays at Allen Fieldhouse. Perhaps its best recognized player was Wilt Chamberlain, who played in the 1950s. Kansas has counted among its coaches Dr. James Naismith (the inventor of basketball and only coach in Kansas history to have a losing record), Basketball Hall of Fame inductee Phog Allen ("the Father of basketball coaching"), Basketball Hall of Fame inductee Roy Williams of the University of North Carolina at Chapel Hill, and Basketball Hall of Fame inductee and former NBA Champion Detroit Pistons coach Larry Brown. In addition, legendary University of Kentucky coach and Basketball Hall of Fame inductee Adolph Rupp played for KU's 1922 and 1923 Helms National Championship teams, and NCAA Hall of Fame inductee and University of North Carolina Coach Dean Smith played for KU's 1952 NCAA Championship team. Both Rupp and Smith played under Phog Allen. Allen also coached Hall of Fame coaches Dutch Lonborg and Ralph Miller. Allen founded the National Association of Basketball Coaches (NABC), which started what is now the NCAA Tournament. The Tournament began in 1939 under the NABC and the next year was handed off to the newly formed NCAA.

The abundant variety of natural life depicted in the Butrint mosaics celebrates the richness of God’s creation; some elements also have specific connotations. The kantharos vase and vine refer to the eucharist, the symbol of the sacrifice of Christ leading to salvation. Peacocks are symbols of paradise and resurrection; shown eating or drinking from the vase they indicate the route to eternal life. Deer or stags were commonly used as images of the faithful aspiring to Christ: "As a heart desireth the water brook, so my souls longs for thee, O God." Water-birds and fish and other sea-creatures can indicate baptism as well as the members of the Church who are christened.

Much civil-defence preparation in the form of shelters was left in the hands of local authorities, and many areas such as Birmingham, Coventry, Belfast and the East End of London did not have enough shelters. The Phoney War, however, and the unexpected delay of civilian bombing permitted the shelter programme to finish in June 1940.:35 The programme favoured backyard Anderson shelters and small brick surface shelters; many of the latter were soon abandoned in 1940 as unsafe. In addition, authorities expected that the raids would be brief and during the day. Few predicted that attacks by night would force Londoners to sleep in shelters.

Y DNA studies tend to imply a small number of founders in an old population whose members parted and followed different migration paths. In most Jewish populations, these male line ancestors appear to have been mainly Middle Eastern. For example, Ashkenazi Jews share more common paternal lineages with other Jewish and Middle Eastern groups than with non-Jewish populations in areas where Jews lived in Eastern Europe, Germany and the French Rhine Valley. This is consistent with Jewish traditions in placing most Jewish paternal origins in the region of the Middle East. Conversely, the maternal lineages of Jewish populations, studied by looking at mitochondrial DNA, are generally more heterogeneous. Scholars such as Harry Ostrer and Raphael Falk believe this indicates that many Jewish males found new mates from European and other communities in the places where they migrated in the diaspora after fleeing ancient Israel. In contrast, Behar has found evidence that about 40% of Ashkenazi Jews originate maternally from just four female founders, who were of Middle Eastern origin. The populations of Sephardi and Mizrahi Jewish communities "showed no evidence for a narrow founder effect." Subsequent studies carried out by Feder et al. confirmed the large portion of non-local maternal origin among Ashkenazi Jews. Reflecting on their findings related to the maternal origin of Ashkenazi Jews, the authors conclude "Clearly, the differences between Jews and non-Jews are far larger than those observed among the Jewish communities. Hence, differences between the Jewish communities can be overlooked when non-Jews are included in the comparisons."
