Infectious diseases are sometimes called contagious disease when they are easily transmitted by contact with an ill person or their secretions (e.g., influenza). Thus, a contagious disease is a subset of infectious disease that is especially infective or easily transmitted. Other types of infectious/transmissible/communicable diseases with more specialized routes of infection, such as vector transmission or sexual transmission, are usually not regarded as "contagious", and often do not require medical isolation (sometimes loosely called quarantine) of victims. However, this specialized connotation of the word "contagious" and "contagious disease" (easy transmissibility) is not always respected in popular use.

While Mont Blanc was first climbed in 1786, most of the Alpine four-thousanders were climbed during the first half of the 19th century; the ascent of the Matterhorn in 1865 marked the end of the golden age of alpinism. Karl Blodig (1859–1956) was among the first to successfully climb all the major 4,000 m peaks. He completed his series of ascents in 1911.

Tuberculosis has been present in humans since antiquity. The earliest unambiguous detection of M. tuberculosis involves evidence of the disease in the remains of bison in Wyoming dated to around 17,000 years ago. However, whether tuberculosis originated in bovines, then was transferred to humans, or whether it diverged from a common ancestor, is currently unclear. A comparison of the genes of M. tuberculosis complex (MTBC) in humans to MTBC in animals suggests humans did not acquire MTBC from animals during animal domestication, as was previously believed. Both strains of the tuberculosis bacteria share a common ancestor, which could have infected humans as early as the Neolithic Revolution.

---

Question: What does MTBC stand for?
Answer: M. tuberculosis complex.

Currents induced into this winding provide the rotor magnetic field. The shape of the rotor bars determines the speed-torque characteristics. At low speeds, the current induced in the squirrel cage is nearly at line frequency and tends to be in the outer parts of the rotor cage. As the motor accelerates, the slip frequency becomes lower, and more current is in the interior of the winding. By shaping the bars to change the resistance of the winding portions in the interior and outer parts of the cage, effectively a variable resistance is inserted in the rotor circuit. However, the majority of such motors have uniform bars.

---

Question: Where can variable resistance be created?
Answer: rotor circuit.

Portuguese cuisine is diverse. The Portuguese consume a lot of dry cod (bacalhau in Portuguese), for which there are hundreds of recipes. There are more than enough bacalhau dishes for each day of the year. Two other popular fish recipes are grilled sardines and caldeirada, a potato-based stew that can be made from several types of fish. Typical Portuguese meat recipes, that may be made out of beef, pork, lamb, or chicken, include cozido à portuguesa, feijoada, frango de churrasco, leitão (roast suckling pig) and carne de porco à alentejana. A very popular northern dish is the arroz de sarrabulho (rice stewed in pigs blood) or the arroz de cabidela (rice and chickens meat stewed in chickens blood).

Uranium is more plentiful than antimony, tin, cadmium, mercury, or silver, and it is about as abundant as arsenic or molybdenum. Uranium is found in hundreds of minerals, including uraninite (the most common uranium ore), carnotite, autunite, uranophane, torbernite, and coffinite. Significant concentrations of uranium occur in some substances such as phosphate rock deposits, and minerals such as lignite, and monazite sands in uranium-rich ores (it is recovered commercially from sources with as little as 0.1% uranium).

In the controversial elections in 2002, Sassou won with almost 90% of the vote cast. His two main rivals, Lissouba and Bernard Kolelas, were prevented from competing and the only remaining credible rival, Andre Milongo, advised his supporters to boycott the elections and then withdrew from the race. A new constitution, agreed upon by referendum in January 2002, granted the president new powers, extended his term to seven years, and introduced a new bicameral assembly. International observers took issue with the organization of the presidential election and the constitutional referendum, both of which were reminiscent in their organization of Congo's era of the one-party state. Following the presidential elections, fighting restarted in the Pool region between government forces and rebels led by Pastor Ntumi; a peace treaty to end the conflict was signed in April 2003.

In the Roman Catholic Church, obstinate and willful manifest heresy is considered to spiritually cut one off from the Church, even before excommunication is incurred. The Codex Justinianus (1:5:12) defines "everyone who is not devoted to the Catholic Church and to our Orthodox holy Faith" a heretic. The Church had always dealt harshly with strands of Christianity that it considered heretical, but before the 11th century these tended to centre around individual preachers or small localised sects, like Arianism, Pelagianism, Donatism, Marcionism and Montanism. The diffusion of the almost Manichaean sect of Paulicians westwards gave birth to the famous 11th and 12th century heresies of Western Europe. The first one was that of Bogomils in modern day Bosnia, a sort of sanctuary between Eastern and Western Christianity. By the 11th century, more organised groups such as the Patarini, the Dulcinians, the Waldensians and the Cathars were beginning to appear in the towns and cities of northern Italy, southern France and Flanders.

Latency results from the methods used to encode and decode the data. Some codecs will analyze a longer segment of the data to optimize efficiency, and then code it in a manner that requires a larger segment of data at one time to decode. (Often codecs create segments called a "frame" to create discrete data segments for encoding and decoding.) The inherent latency of the coding algorithm can be critical; for example, when there is a two-way transmission of data, such as with a telephone conversation, significant delays may seriously degrade the perceived quality.

The Logic and Metaphysics have been extensively reprinted, the latter, e.g., at Venice in 1493, 1495, and 1546. Some of his shorter essays on medicine, logic, etc., take a poetical form (the poem on logic was published by Schmoelders in 1836).[citation needed] Two encyclopaedic treatises, dealing with philosophy, are often mentioned. The larger, Al-Shifa' (Sanatio), exists nearly complete in manuscript in the Bodleian Library and elsewhere; part of it on the De Anima appeared at Pavia (1490) as the Liber Sextus Naturalium, and the long account of Ibn Sina's philosophy given by Muhammad al-Shahrastani seems to be mainly an analysis, and in many places a reproduction, of the Al-Shifa'. A shorter form of the work is known as the An-najat (Liberatio). The Latin editions of part of these works have been modified by the corrections which the monastic editors confess that they applied. There is also a حكمت مشرقيه (hikmat-al-mashriqqiyya, in Latin Philosophia Orientalis), mentioned by Roger Bacon, the majority of which is lost in antiquity, which according to Averroes was pantheistic in tone.

A mummified man, determined to be 5,000 years old, was discovered on a glacier at the Austrian–Italian border in 1991. By the 6th century BC, the Celtic La Tène culture was well established. Hannibal famously crossed the Alps with a herd of elephants, and the Romans had settlements in the region. In 1800 Napoleon crossed one of the mountain passes with an army of 40,000. The 18th and 19th centuries saw an influx of naturalists, writers, and artists, in particular the Romantics, followed by the golden age of alpinism as mountaineers began to ascend the peaks. In World War II, Adolf Hitler kept a base of operation in the Bavarian Alps throughout the war.

Several influential people of the time, including Bell, viewed deafness as something that should be eradicated, and also believed that with resources and effort they could teach the deaf to speak and avoid the use of sign language, thus enabling their integration within the wider society from which many were often being excluded. In several schools, children were mistreated, for example by having their hands tied behind their backs so they could not communicate by signing—the only language they knew—in an attempt to force them to attempt oral communication. Owing to his efforts to suppress the teaching of sign language, Bell is often viewed negatively by those embracing Deaf culture.

From the beginning of 2014, Madonna began to make multiple media appearances. She appeared at the 56th Annual Grammy Awards in January 2014, performing "Open Your Heart" alongside rappers Macklemore & Ryan Lewis and singer Mary Lambert, who sang their single "Same Love", as 33 couples were wed onstage, officiated by Queen Latifah. Days later, she joined singer Miley Cyrus on her MTV Unplugged special, singing a mash-up of "Don't Tell Me" and Cyrus' single "We Can't Stop" (2013). She also extended her business ventures and in February 2014 the singer premiered MDNA Skin, a range of skin care products, in Tokyo, Japan. After visiting her hometown of Detroit during May 2014, Madonna decided to contribute funds to three of the city's organizations, to help eliminate poverty from there. The singer released a statement saying that she was inspired by their work, adding that "it was obvious to me that I had to get involved and be part of the solution to help Detroit recover".

This changed with the recent sovereign-debt crisis. The ECB always could, and through the late summer of 2011 did, purchase bonds issued by the weaker states even though it assumes, in doing so, the risk of a deteriorating balance sheet. ECB buying focused primarily on Spanish and Italian debt. Certain techniques can minimise the impact. Purchases of Italian bonds by the central bank, for example, were intended to dampen international speculation and strengthen portfolios in the private sector and also the central bank.

The first lighting used on an airport was during the latter part of the 1920s; in the 1930s approach lighting came into use. These indicated the proper direction and angle of descent. The colours and flash intervals of these lights became standardized under the International Civil Aviation Organization (ICAO). In the 1940s, the slope-line approach system was introduced. This consisted of two rows of lights that formed a funnel indicating an aircraft's position on the glideslope. Additional lights indicated incorrect altitude and direction.

During the 18th century, systems of plant identification were developed comparable to dichotomous keys, where unidentified plants are placed into taxonomic groups (e.g. family, genus and species) by making a series of choices between pairs of characters. The choice and sequence of the characters may be artificial in keys designed purely for identification (diagnostic keys) or more closely related to the natural or phyletic order of the taxa in synoptic keys. By the 18th century, new plants for study were arriving in Europe in increasing numbers from newly discovered countries and the European colonies worldwide. In 1753 Carl von Linné (Carl Linnaeus) published his Species Plantarum, a hierarchical classification of plant species that remains the reference point for modern botanical nomenclature. This established a standardised binomial or two-part naming scheme where the first name represented the genus and the second identified the species within the genus. For the purposes of identification, Linnaeus's Systema Sexuale classified plants into 24 groups according to the number of their male sexual organs. The 24th group, Cryptogamia, included all plants with concealed reproductive parts, mosses, liverworts, ferns, algae and fungi.

New chemical glass compositions or new treatment techniques can be initially investigated in small-scale laboratory experiments. The raw materials for laboratory-scale glass melts are often different from those used in mass production because the cost factor has a low priority. In the laboratory mostly pure chemicals are used. Care must be taken that the raw materials have not reacted with moisture or other chemicals in the environment (such as alkali or alkaline earth metal oxides and hydroxides, or boron oxide), or that the impurities are quantified (loss on ignition). Evaporation losses during glass melting should be considered during the selection of the raw materials, e.g., sodium selenite may be preferred over easily evaporating SeO2. Also, more readily reacting raw materials may be preferred over relatively inert ones, such as Al(OH)3 over Al2O3. Usually, the melts are carried out in platinum crucibles to reduce contamination from the crucible material. Glass homogeneity is achieved by homogenizing the raw materials mixture (glass batch), by stirring the melt, and by crushing and re-melting the first melt. The obtained glass is usually annealed to prevent breakage during processing.

Question: Why is glass annealed?
Answer: to prevent breakage.

Text is frequently incorporated into comics via speech balloons, captions, and sound effects. Speech balloons indicate dialogue (or thought, in the case of thought balloons), with tails pointing at their respective speakers. Captions can give voice to a narrator, convey characters' dialogue or thoughts, or indicate place or time. Speech balloons themselves are strongly associated with comics, such that the addition of one to an image is sufficient to turn the image into comics. Sound effects mimic non-vocal sounds textually using onomatopoeia sound-words.

Question: What association with comics is strong?
Answer: Speech balloons.

In the midst of the European sovereign-debt crisis, Radek Sikorski, Poland's Foreign Minister, stated in November 2011, "I will probably be the first Polish foreign minister in history to say so, but here it is: I fear German power less than I am beginning to fear German inactivity. You have become Europe's indispensable nation." According to Jacob Heilbrunn, a senior editor at The National Interest, such a statement is unprecedented when taking into consideration Germany's history. "This was an extraordinary statement from a top official of a nation that was ravaged by Germany during World War II. And it reflects a profound shift taking place throughout Germany and Europe about Berlin's position at the center of the Continent." Heilbrunn believes that the adage, "what was good for Germany was bad for the European Union" has been supplanted by a new mentality—what is in the interest of Germany is also in the interest of its neighbors. The evolution in Germany's national identity stems from focusing less on its Nazi past and more on its Prussian history, which many Germans believe was betrayed—and not represented—by Nazism. The evolution is further precipitated by Germany's conspicuous position as Europe's strongest economy. Indeed, this German sphere of influence has been welcomed by the countries that border it, as demonstrated by Polish foreign minister Radek Sikorski's effusive praise for his country's western neighbor. This shift in thinking is boosted by a newer generation of Germans who see World War II as a distant memory.

In 2012, news was released about a new farming site discovered in Munam-ri, Goseong, Gangwon Province, South Korea, which may be the earliest farmland known to date in east Asia. "No remains of an agricultural field from the Neolithic period have been found in any East Asian country before, the institute said, adding that the discovery reveals that the history of agricultural cultivation at least began during the period on the Korean Peninsula". The farm was dated between 3600 and 3000 B.C. Pottery, stone projectile points, and possible houses were also found. "In 2002, researchers discovered prehistoric earthenware, jade earrings, among other items in the area". The research team will perform accelerator mass spectrometry (AMS) dating to retrieve a more precise date for the site.
