- (C) India on 30th of September 2014, signed Minamata Convention. The Minamata Convention on Mercury is a global treaty to protect human health and the environment from the adverse effects of mercury. It was agreed at the fifth session of the Intergovernmental Negotiating Committee in Geneva, Switzerland on January 19, 2013.
- (A) Thalassaemia is the name we give to a group of related conditions. These conditions affect haemoglobin the substance in our blood that carries oxygen around our body. Some conditions are more serious than others. The most serious forms are called beta thalassaemia major and alpha thalassaemia
- (A) Interferons (IFNs) are a group of signaling proteins made and released by host cells in response to the presence of pathogens, such as viruses, bacteria, parasites, or tumor cells such as in cancer. In a typical scenario, a virus-infected cell will release interferons causing nearby cells to heighten their anti-viral defenses.
- (C) Washington Accord is an international agreement amongst prominent nations of the world,
with the charter of promoting mobility and quality assurance of engineers across international boundaries. India now joins a select group of 17 countries who are permanent signatories of the WA.
- (B) Gout is caused by too much uric acid in the blood (hyperuricemia). The exact cause of hyperuricemia sometimes isn’t known, although inherited factors (genes) seem to play a role.Uric acid may form crystals that build up in the joints. This causes the pain and other symptoms.
- (C) Diabetes mellitus (DM), commonly referred to as diabetes, is a group of metabolic diseases in which there are high blood sugar levels over a prolonged period. Symptoms of high blood sugar include frequent urination, increased thirst, and increased hunger. If left untreated, diabetes can cause many complications. Acute complications include diabetic ketoacidosis and nonketotic hyperosmolar coma. Serious long-term complications include cardiovascular disease, stroke, chronic kidney failure, foot ulcers, and damage to the eyes Diabetes is due to either the pancreas not producing enough insulin or the cells of the body not responding properly to the insulin produced.
- (B) The ionosphere is a region of Earth’s upper atmosphere, from about 60 km (37 mi) to 600 km (370 mi) altitude, And includes the thermosphere and parts of the mesosphere and exosphere. It is distinguished because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. It has practical importance because, among other functions, it causes the reflection of radio waves to Earth.
- (D) The ratification of Nagoya Protocol is crucial step for achievement of first of the international Aichi Biodiversity Targets. The Nagoya protocol is meant for creation of incentives for conservation of biodiversity. The Nagoya Protocol has
received the 50th instrument of ratification.
- (B) Influenza A virus subtype H5N1, also known as A(H5N1) or simply H5N1, is a subtype of the influenza a virus which can cause illness in humans and many other animal species.A bird-adapted strain of H5N1, called HPAI A(H5N1) for highly pathogenic avian influenza virus of type A of subtype H5N1, is the highly pathogenic causative agent of FI5N1 flu, commonly known as avian influenza (“bird flu”). It is enzootic(maintained in the population) in many bird populations, especially in Southeast Asia. One strain of HPAIA(H5N1) is spreading globally after first appearing in Asia.
- (C) Charles Babbage invented the first computer in 1837. He gave the name of The Analytical Engine. He is the father of computer.
- (B) Colossus was the name of a series of computers developed for British code breakers in 1943- 1945 to help in the cryptanalysis of the Lorenz cipher. Colossus use thermionic valves (vacuum tubes) and thyratrons to perform Boolean and counting perations. Colossus is thus regardedas the world’s first programmable, electronic, digital computer, although it was programmed by plugs and switches and not by a storedyprogram. Colossus was designed by the engineer Tommy Flowers to solve a problem posed by mathematician Max Newman at the Government Code and Cypher School (GC&CS) at Bletchley Park. Alan Turing’s use of probability in cryptanalysis contributed to its design. It has sometimes been erroneously stated that Turing designed Colossus to aid the Cryptanalys is of the Enigma Turing’s machine that helped decode Enigma was the electromechanical Bombe, not Colossus.
- (D) According to the UN nuclear agency IAEA there are many benefits with thorium compared to uranium, which is currently used in nuclear reactors.To begin
with, there is limited radioactive debris when thorium is used. And interms of chemical stability and resistance to radioactivity thorium is a safer alternative compared to uranium. Depending on the core process utilized, thorium leads to more energy that can be recovered from this cheap, available and relatively safe energy.One of the major drawbacks of nuclear power is the fear that countries that have the technology will use it to acquire nuclear weapons. This is much more difficult to do with the material that is created in nuclear reactors fueled with thorium compared to those that run on uranium.
- (B) NAYAN (Network Abhigam niYantrAN) addresses the access control and authentication requirements of a local area network. NAYAN controls the access to different network services at the end system level, protecting internal network from rapidly propagating threats and network misuse. NAYAN unifies End System Authentication, Desktop Firewft’l with Centralize Administration, Automatic Policy Updating and Role Based Access Control.
- (A) ‘Virtual Private Network’ are popular amongst bigwig corporates who wish to have secured communications through public internet Service Providers but have an arrangement with the ISPs to make the data transfer safe and confidential.
- (B) India’s First Supercomputer was PARAM 8000. PARAM stood for Parallel Machine. The computer was developed by the government run Center for Development of Advan Gigaflop (billion floating point operations per second).
- (C) It is required to limit the current in the tube while in operation the design also provides necessary resistance for the filament to glow for starting the lamp. It provides the starting pulse voltage to get the spark to leap in the tube. “The ballast used in this circuit is essentially a choke and capacitor in series.
The capacitor corrects the phase lag caused by the choke and improves the efficiency. The inductance of the choke causes a voltage spike when the starters witches off. This is due to the sudden change in current flow and can help achieve the initial spark required to start the fluorescent tube. The choke controls the current once the tube has been started, as it has a high impedance at the operating frequency of the tube (about 20kHz). It has alow impedance during start-up when the mains current flows through the cathodes and starter at 50Hz.” Choke essentially is an inductor responsible for providing the required lagin the voltage (this lag increases the voltage between the plates) and hence the ions start emitting or light glows.
- (B) Germanium is the chemical element of atomic number 32, a shiny grey semimetal. It was important in the making of transistors and other semiconductor devices, but has been largely replaced by silicon. Silicon is the eighth most common element in the universe by mass, but very rarely occurs as the pure free element in nature.

Agriculture accounts for about 33% of the gross domestic production, with tea, coffee, flowers, pyre- thrum, sisal, sugar and cotton as the principal cash crops for export. Tea and coffee accounts for some 25% and 14% of export earning respectively. Maize is a staple food augmented by rice, wheat, sugar, sorghum, pulses, potatoes and bananas. About 10% of the monetary economy is based on manufacturing. Petroleum products are exported, though crude oil is imported. Food processing, tobacco, beverages, textiles, vehicle assembly, petroleum products, paper, chemicals, cement and machinery. Industries rely on hydroelectric power, geothermal power and imported fuels. Sodaash, flourspar, salt and limestone, gemstone including ruby, aquamarine, quartz and amethyat are also found. jjgSiii
