Re: General Quiz

Hi bobbym,

The Answer #5618 is correct! Excellent!

#5619. Name an instrument used to measure pain threshold and pain tolerance. The subject has been defined as "the measurement of pain sensitivity or pain intensity." There are several kinds of them that have been developed. They apply steady pressure, heat, or electrical stimulation to some area, or move a joint or other body part and determine what level of heat or pressure or electric current or amount of movement produces a sensation of pain. Sometimes the pressure is applied using a blunt object, or by locally increasing the air pressure on some area of the body, and sometimes by pressing a sharp instrument against the body.

#5620. Name the term term : It means "old eye" and is a vision condition involving the loss of the eye's ability to focus on close objects.
Description : It is a condition that occurs as a part of normal aging and is not considered to be an eye disease. The process occurs gradually over a number of years. Symptoms are usually noticeable by age 40-45 and continue to develop until the process stabilizes some 10-20 years later.  It occurs without regard to other eye conditions.

Hi bobbym,

The Answer #5619 is correct! Excellent!

#5621. The Thar Desert, also known as the Great Indian Desert, is a large, arid region in the northwestern part of the Indian subcontinent that forms a natural boundary between India and Pakistan. It is the world's 17th largest desert, and the world's 9th largest subtropical desert. About 85% of the Thar Desert is in India, and the remaining part in Pakistan.

#5622. The Gobi is a large desert region in Asia. It covers parts of northern and northwestern China, and of southern Mongolia. The desert basins of the Gobi are bounded by the Altai Mountains and the grasslands and steppes of Mongolia on the north, by the Taklamakan Desert to the West, by the Hexi Corridor and Tibetan Plateau to the southwest, and by the North China Plain to the southeast. The Gobi is most notable in history as part of the great Mongol Empire, and as the location of several important cities along the Silk Road. Find its area is square kilometers or square miles.

#5635.  Name a spherical fullerene molecule with the formula

. It has a cage-like fused-ring structure (truncated icosahedron) which resembles a football (soccer ball), made of twenty hexagons and twelve pentagons, with a carbon atom at each vertex of each polygon and a bond along each polygon edge. It was first generated in 1985 by Harold Kroto, James R. Heath, Sean O'Brien, Robert Curl, and Richard Smalley at Rice University. Kroto, Curl and Smalley were awarded the 1996 Nobel Prize in Chemistry for their roles in the discovery of it.

#5636. Name the term / phrase in Chemistry :  A zinc-carbon primary cell (colloquially called a "battery") composed of a zinc anode in dilute sulfuric acid separated by a porous pot from a carbon cathode in nitric or chromic acid.

#5637. Name the theorem in probability : In probability theory and statistics, it describes the probability of an event, based on conditions that might be related to the event. For example, suppose one is interested in whether Addison has cancer, and that she is 65. If cancer is related to age, information about Addison's age can be used to more accurately assess the probability of her having cancer using this Theorem.

#5638. BCS theory is the first microscopic theory of superconductivity since its discovery in 1911. The theory describes superconductivity as a microscopic effect caused by a condensation of Cooper pairs into a boson-like state. The theory is also used in nuclear physics to describe the pairing interaction between nucleons in an atomic nucleus. It was proposed by John Bardeen, Leon Cooper, and John Robert Schrieffer ("BCS") in 1957. In which year did they receive the Nobel Prize in Physics for this theory?

#5639.  Name the process -  (also known as Linz-Donawitz-Verfahren steelmaking) - A method of primary steelmaking in which carbon-rich molten pig iron is made into steel. Blowing oxygen through molten pig iron lowers the carbon content of the alloy and changes it into low-carbon steel. The process is known as basic because fluxes of burnt lime or dolomite, which are chemical bases, are added to promote the removal of impurities and protect the lining of the converter.

#5640. Name the Soviet physicist and educator (14 December 1922 – 1 July 2). For his fundamental work in the field of quantum electronics that led to the development of laser and maser, he shared the 1964 Nobel Prize in Physics with Alexander Prokhorov and Charles Hard Townes.

Re: General Quiz

Hi bobbym,

#5641. Name the instrument / gadget -  a device used to measure small differences of temperature, but not absolute temperature values. Invented (1853 – 1923) by a German chemist, for his measurements of colligative properties in 1905. Today its use has largely been superseded by electronic thermometers.
Thermometer's length is usually 40 – 50 cm. The temperature scale typically covers about 5 °C and it is divided into hundredths of a degree. With a magnifier it is possible to estimate temperature changes to 0.001 °C. The peculiarity of this thermometer design is a reservoir (R on diagram) at the upper end of the tube, by means of which the quantity of mercury in the bulb can be increased or diminished so that the instrument can be set to measure temperature differences at either high or low temperature values. In contrast, the range of a typical mercury-in-glass thermometer is fixed, being set by the calibration marks etched on the glass or the marks on the printed scale.

#5642.  Name the German chemist known (11 October 1884 – 30 March 1949) for the process on his name  for producing synthetic fuel from coal, Nobel Prize in Chemistry (1931, together with Carl Bosch) in recognition of contributions to the invention and development of chemical high-pressure methods. Having worked with IG Farben during World War II, his citizenship came into question following the war, causing him to ultimately flee to Argentina, where he acted as adviser to the Ministry of Industry.

Hi bobbym,

The Answer #5642 is correct! Brilliant!

#5643. Name the German astronomer, mathematician, physicist and geodesist  (22 July 1784 – 17 March 1846). He was the first astronomer who determined reliable values for the distance from the sun to another star by the method of parallax. A special type of mathematical functions were named after these functions after his death, though they had originally been discovered by Daniel Bernoulli.

#5644. Name the  a cyclic particle accelerator developed by Donald Kerst at the University of Illinois in 1940 to accelerate electrons, but the concepts ultimately originate from Rolf Widerøe, whose development of an induction accelerator failed due to the lack of transverse focusing. Previous development in Germany also occurred through Max Steenbeck in the 1940s. It is essentially a transformer with a torus-shaped vacuum tube as its secondary coil. An alternating current in the primary coils accelerates electrons in the vacuum around a circular path. It was the first important machine for producing high energy electrons.
