Q.1 Recently which among the following state has adopted fly ash utilization policy ? A) Maharashtra B) Punjab C) Karnataka D) Tamil Nadu Ans. A Fly ash is a fine, glass powder by-product recovered from gases of burning coal in thermal power plants during production of electricity. They are micron sized earth elements primarily consisting silica, alumina and iron. Fly ash causes air pollution. It can also contaminate water and soil systems. The wet disposal of Fly ash results in leaching of toxic heavy metals in ground water system. Q.2 DNA Index System (DIS) allows generation of DNA profiles from which of the following samples : 1. Saliva 2. Blood strains 3. Buccal Swabs Select the correct answer using the codes given below : A) Only 1 B) 1 & 3 C) 1,2,3 D) 1 & 2 Ans. C DNA profiling (also called DNA fingerprinting, DNA testing, or DNA typing) is a forensic technique used to identify individuals by characteristics of their DNA. A DNA profile is a small set of DNA variations that is very likely to be different in all unrelated individuals, thereby being as unique to individuals as are fingerprints (hence the alternate name for the technique). DNA profiling should not be confused with full genome sequencing. DNA fingerprinting has also been widely used in the study of animal and floral populations and has revolutionized the fields of zoology, botany, and agriculture A common method of collecting a reference sample is the use of a buccal swab, which is easy, non-invasive and cheap. When this is not available (e.g. because a court order is needed but not obtainable) other methods may need to be used to collect a sample of blood, saliva, semen, or other appropriate fluid or tissue from personal items (e.g. a toothbrush, razor) or from stored samples (e.g. banked sperm or biopsy tissue). Samples obtained from blood relatives (related by birth, not marriage) can provide an indication of an individual’s profile, as could human remains that had been previously profiled. Using PCR technology, DNA analysis is widely applied to determine genetic family relationships such as paternity, maternity, siblingship and other kinships. Familial DNA searching (sometimes referred to as “Familial DNA” or “Familial DNA Database Searching”) is the practice of creating new investigative leads in cases where DNA evidence found at the scene of a crime (forensic profile) strongly resembles that of an existing DNA profile (offender profile) in a state DNA database but there is not an exact match. Q.3 HIMANSH often in the news is : A) Glaciological research station B) Submarine vessel C) Micro satellite D) Nuclear Vessel Ans.

Q.8 With reference to the LIDAR (Light Detection & ranging) consider the following statements : 1. LIDAR uses ultraviolet & visible light only to detect the objects 2. They can target a wide range of materials except non-metallic objects Select the correct answer using the codes given below : A) Only 1 B) Only 2 C) Both are correct D) Both are incorrect Ans. D Lidar uses ultraviolet, visible, or near infrared light to image objects. It can target a wide range of materials, including non-metallic objects, rocks, rain, chemical compounds, aerosols, clouds and even single molecules.A narrow laser-beam can map physical features with very high resolutions; for example, an aircraft can map terrain at 30-centimetre (12 in) resolution or better. Lidar has been used extensively for atmospheric research and meteorology. Lidar instruments fitted to aircraft and satellites carry out surveying and mapping – a recent example being the U.S. Geological Survey Experimental Advanced Airborne Research Lidar.NASA has identified lidar as a key technology for enabling autonomous precision safe landing of future robotic and crewed lunar-landing vehicles. Wavelengths vary to suit the target: from about 10 micrometers to the UV (approximately 250 nm). Typically light is reflected via backscattering. Different types of scattering are used for different lidar applications: most commonly Rayleigh scattering, Mie scattering, Raman scattering, and fluorescence. Based on different kinds of backscattering, the lidar can be accordingly called Rayleigh Lidar, Mie Lidar, Raman Lidar, Na/Fe/K Fluorescence Lidar, and so on. Suitable combinations of wavelengths can allow for remote mapping of atmospheric contents by identifying wavelength-dependent changes in the intensity of the returned signal. In general there are two kinds of lidar detection schemes: “incoherent” or direct energy detection (which is principally an amplitude measurement) and coherent detection (which is best for Doppler, or phase sensitive measurements). Coherent systems generally use optical heterodyne detection, which, being more sensitive than direct detection, allows them to operate at a much lower power but at the expense of more complex transceiver requirements. Lidar is popularly used to make high-resolution maps, with applications in geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, laser guidance, airborne laser swath mapping (ALSM), and laser altimetry. Lidar sometimes is called laser scanning and 3D scanning, with terrestrial, airborne, and mobile applications. Q.9 With reference to the fast neutron reactor

Q.1 Which among the following is/are the features that characterizes the Pioneer species ? 1. Most of them are hardy species with non-photosynthetic activity 2. The plants that are often pioneer species tend to be insect-pollinated 3. Orchids, lichens & Algae are the examples of the pioneer species Select the correct answer using the codes given below : A) Only 1 B) 2 & 3 C) 1 & 2 D) Only 3 Ans. D Examples of the plants and organism that colonize such areas are pioneer species: • Barren sand – lyme grass (Leymus arenarius), sea couch grass (Agropyron pungens), Marram grass (Ammophila breviligulata) • Salt water – green algae, marine eel grass (Zostera spp.), pickleweed (Salicornia virginica), and cordgrass (hybrid Spartina × townsendii) and (Spartina anglica). • Clear water – algae, mosses, freshwater eel grass (Vallisneria americana). • Solidified lava flows – in Hawaii: swordfern (Polystichum munitum), ‘ōhi‘a lehua (Metrosideros polymorpha), ‘ohelo (Vaccinium reticulatum) and ‘āma‘u (Sadleria cyatheoides);[3] on Surtsey: lichen (Stereocaulon vesuvianum and Placopsis gelida) and moss (Racomitriumericoides);[4] green algae • Disturbed areas such as construction sites, road cuttings and verges, cultivated lands – Buddleia davidii, Nettles[clarification needed], Tagetes minuta, Bidens pilosa, Argemone mexicana • Bare clay – Orchids • Mountains – Lichens Pioneer species are hardy species which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession that ultimately leads to a more biodiverse steady-state ecosystem Since some uncolonized land may have thin, poor quality soils with few nutrients, pioneer species are often hardy plants with adaptations such as long roots, root nodes containing nitrogen-fixing bacteria, and leaves that employ transpiration. They are often photosynthetic plants, as no other source of energy (such as other species) except light energy is often available in the early stages of succession, thus making it less likely for a pioneer species to be non-photosynthetic. The plants that are often pioneer species also tend to be wind-pollinated rather than insect-pollinated, Pioneering fauna will colonize an area only after flora and fungi have inhabited the area. Soil fauna, ranging from microscopic protists to larger invertebrates, have a role in soil formation and nutrient cycling. Bacteria and fungi are the most important groups in the breakdown of organic detritus left by primary producing plants such as skeletal soil, moss and algae. Though vertebrates in general would not be considered pioneer species, there are exceptions Pioneer species can also be found in secondary succession, such as an established ecosystem being reduced by an event such as: a forest fire, deforestation, or clearing; quickly colonizing open spaces which previously supported vegetation. Common examples of the plants in such areas include • Raspberry – Rubus spp. • Heaths – Ericaceae spp. • Graminoids, forbs, and wildflowers – native, introduced, and invasive species: such as fire dependent seed, cone, and resprouter chaparral genera. Q.2 Which among the following plants is/are classified under the category of aquatic plants ? 1. Duckweed 2. Water Hyacinth 3. Lotus Select the correct answer using the codes given below : A) Only 3 B) 2 & 3 C) 1 & 2 D) 1,2,3 Ans. D One of the largest aquatic plants in the world is the Amazon water lily; one of the smallest is the minute duckweed. Many small aquatic animals use plants like duckweed for a home, or for protection from predators, but areas with more vegetation are likely to have more predators. Some other familiar examples of aquatic plants might include floating heart, water lily, lotus, and water hyacinth. Some aquatic plants are used by humans as a food source. Examples include wild rice (Zizania), water caltrop (Trapa natans), Chinese water chestnut (Eleocharis dulcis), Indian lotus (Nelumbo nucifera), water spinach (Ipomoea aquatica), and watercress (Rorippa nasturtium-aquaticum). Q.3 Which among the following equipment(s) comes under the classification of energy efficient schemes ? 1. LED bulbs 2. Fans 3.LED tube lights 4. Street lights Select the correct answer using the codes given below : A) 1,2,3 B) Only 1 & 3 C) 1,3,4 D) 1,2,3,4 Ans. D Solar water pump sets : At present, solar water pumping system market in India is subsidy driven. Non-subsidized pumps accounts for marginal share in the market. High capital cost is the major hurdle in the growth of solar water pumping system market. Regardless of subsidies provided by the government, solar pumps are still unaffordable for small farmers due to their high upfront cost in comparison to diesel and electric pumps. With this background, EESL intends to develop a programme to provide a reliable source of supply to agricultural pump sets which are currently being operated by diesel generators or through grid supply by way of solar mini grids. By developing such renewable energy based grids, farmers will be able to receive considerable revenue on monthly basis by selling the excess power to the grid for a period of 25 years. The benefits of the programme to the farmers includes social emancipation as well as contribution to the society by means of water conservation Q.4 With reference to the news there was a term “TERM CELLS”, What is this ? A) It is an alternative of Stem cells that can differentiate into specialized cells B) It is the vigilance and monitoring wing of the Indian Department of Telecommunications C) These are the tiny cells in the form of pins that are used in laptops, torches, etc. D) It has been set up by the government to combat illegal trafficking Ans. B Telecom Enforcement Resource and Monitoring (TERM), formerly known as Vigilance Telecom Monitoring (VTM), is the vigilance and monitoring wing of the Indian Department of Telecommunications (DoT) TERM is made up of 34 Cells in India’s 22 telecom circles and 10 large telecom districts,[2] each headed by a Senior Administrative Grade (SAG) level officer, termed as Deputy Director General (DDG).The main functions of TERM Cells are vigilance, monitoring and security of the network.Apart from this, TERM Cells also operate the Central Monitoring System (CMS), a clandestine mass electronic surveillance

Q.2 Which of the following is/are true with respect to the coliform bacteria? 1. These are present in large numbers in the feces of cold-blooded animals 2. These are restricted to the aquatic environment 3. These are the common indicator of sanitary quality of foods and water Select the correct answer using the codes given below : A) Only 1 B) 2 & 3 C) Only 3 D) 1,2,3 Ans. C Coliform bacteria are defined as rod-shaped Gram-negative non-spore forming and motile or non-motile bacteria which can ferment lactosewith the production of acid and gas when incubated at 35–37°C. They are a commonly used indicator of sanitary quality of foods and water. Coliforms can be found in the aquatic environment, in soil and on vegetation; they are universally present in large numbers in the feces of warm-blooded animals. Whilst coliforms themselves are not normally causes of serious illness, they are easy to culture, and their presence is used to indicate that other pathogenic organisms of fecal origin may be present. Such pathogens include disease-causing bacteria, viruses, or protozoa and many multicellular parasites. Coliform procedures are performed in aerobic or anaerobic conditions. Q.3 With reference to the S-band spectrum, consider the following statements : 1. It is part of the microwave & Infrared band of the electromagnetic spectrum 2. It is standard for radio waves with frequencies that range from 2 to 4 GHz, 3. The S band is used by all communications satellites to communicate with the Space Shuttle and the International Space Station. Select the correct answer using the codes given below : A) 1 & 3 B) Only 2 C) 2 & 3 D) 1 & 2 Ans. B The S band is part of the microwave band of the electromagnetic spectrum. It is defined by an IEEE standard for radio waves with frequencies that range from 2 to 4 GHz, crossing the conventional boundary between UHF and SHF at 3.0 GHz. The S band is used by weather radar, surface ship radar, and some communications satellites, especially those used by NASA to communicate with the Space Shuttle and the International Space Station. The 10 cm radar short-band ranges roughly from 1.55 to 5.2 GHz. In some countries, S band is used for Direct-to-Home satellite television (unlike similar services in most countries, which use Ku band). The frequency typically allocated for this service is 2.5 to 2.7 GHz (LOF 1.570 GHz). Q.4 Which among the following is/are true with respect to the Bio banks ? 1.

Mostly grasses such as cereals, lawn turf, and grassland relatively unaffected by this herbicide Select the correct answer using the codes given below : A) Only 1 B) Only 2 C) Both are correct D) Both are incorrect Ans. B 2,4-Dichlorophenoxyacetic acid (usually called 2,4-D) is an organic compound with the chemical formula C8H6Cl2O3. It is a systemic herbicide which selectively kills most broadleaf weeds by causing uncontrolled growth in them, but leaves most grasses such as cereals, lawn turf, and grassland relatively unaffected.  It can be found in numerous commercial lawn herbicide mixtures, and is widely used as a weedkiller on cereal crops, pastures, and orchards. 2,4-D was one of the ingredients in Agent Orange, a herbicide widely used during the Vietnam War 2,4-D is primarily used as a selective herbicide which kills many terrestrial and aquatic broadleaf weeds, but not grasses.  It acts by mimicking the action of the plant growth hormone auxin, which results in uncontrolled growth and eventually death in susceptible plants  In agriculture, it was the first herbicide found to be capable of selectively killing weeds but not crops.  It is often used by government agencies to control the spread of invasive, noxious and non-native weed species and prevent them from crowding out native species, and also to control many poisonous weeds such as poison ivy and poison oak Men who work with 2,4-D are at risk for abnormally shaped sperm and thus fertility problems; Residue levels in kidney were the highest 2,4-D is a synthetic auxin, which is a class of plant hormones. Q.3 Which among the following is/are true with respect to the subatomic particles Baryon ? 1. These are the quark-based particles that participate in the strong interaction 2. They are similar in functioning as compared to the lepton & Mesons 3. Protons & neutrons are the only baryons that make up most of the mass of the visible matter in the universe Select the correct answer using the codes given below : A) 1 & 2 B) 2 & 3 C) Only 1 D) 1,2,3 Ans. C A baryon is a composite subatomic particle made up of three quarks (a triquark, as distinct from mesons, which are composed of one quark and one antiquark). Baryons and mesons belong to the hadron family of particles, which are the quark-based particles. As quark-based particles, baryons participate in the strong interaction, whereas leptons, which are not quark-based, do not. The most familiar baryons are the protons and neutrons that make up most of the mass of the visible matter in the universe. Electrons (the other major component of the atom) are leptons. Each baryon has a corresponding antiparticle (antibaryon) where quarks are replaced by their corresponding antiquarks. For example, a proton is made of two up quarks and one down quark; and its corresponding antiparticle, the antiproton, is made of two up antiquarks and one down antiquark. Q.4 Which among the following is/are the examples of the e-liquids that are used in e-cigarettes ? 1. Water 2. Nicotine 3. Glycerine Select the correct answer using the codes given below : A) Only 2 B) 2 & 3 C) 1 & 3 D) 1,2,3 Ans. D An electronic cigarette or e-cigarette is a handheld electronic device that tries to create the feeling of tobacco smoking. It works by heating a liquid to generate an aerosol, commonly called a “vapor”, that the user inhales. Using e-cigarettes is sometimes called vaping. The liquid in the e-cigarette, called e-liquid, is usually made of nicotine, propylene glycol, glycerine, and flavorings. Not all e-liquids contain nicotine The health risks of e-cigarettes are uncertain. They are likely safer than tobacco cigarettes, but the long-term health effects are not known They can help some smokers quit. When used by non-smokers, e-cigarettes can lead to nicotine addiction, and there is concern that children could start smoking after using e-cigarettes  Less serious adverse effects include throat and mouth irritation, vomiting, nausea, and coughing The majority of toxic chemicals found in tobacco smoke are absent in e-cigarette aerosol. Those present are mostly below 1% corresponding levels in tobacco smoke The emergence of e-cigarettes has given cannabis smokers a new method of inhaling cannabinoids. E-cigarettes differ from traditional marijuana cigarettes in several respects. It is assumed that vaporizing cannabinoids at lower temperatures is safer because it produces smaller amounts of toxic substances than the hot combustion of a marijuana cigarette E-liquid is the mixture used in vapor products such as e-cigarettes and generally consists of propylene glycol, glycerin, water, nicotine, and flavorings Smoking a traditional cigarette yields between 0.5 and 1.5 mg of nicotine, but the nicotine content of the cigarette is only weakly correlated with the levels of nicotine in the smoker’s bloodstream  Nicotine in tobacco smoke is absorbed into the bloodstream rapidly, and e-cigarette vapor is relatively slow in this regard. The concentration of nicotine in e-liquid ranges up to 36 mg/Ml Q.5 Which among the following is/are true in context with the 5-star rated celing fans ? 1. These are 50% more energy efficient as compared to the conventional fans 2.

Q.1 With reference to the “Polargap Project” ,consider the following statements : 1. It is an international mission to capture data about the Earth’s electrical & magnetic field 2. This project is largely funded by the World bank Which of the statements given above is/are correct ? A) Only  1 B) Only 2 C) Both are correct D) Both are incorrect Ans. D PolarGAP is an ambitious international mission to capture new and critical data about the Earth’s global gravity field.  Innovative radar systems and Lidar technologies will also be deployed from Twin Otter aircraft to fill the ‘data gap’ in measurements of surface elevation over the South Pole region south of 83.5°. Two earth observing satellite missions (GOCE and CryoSat 2) mounted by the European Space Agency (ESA) revolutionised scientists’ ability to ‘map’ the Earth’s global gravity field and monitor how Earth’s ice fields are responding to global change.  However, because GOCE’s orbit did not cross the Poles there is a data gap at the South Pole. The PolarGAP project will collect new gravity data and combine them with datasets from other Antarctic missions to build the first accurately constrained global gravity model. This is essential as global gravity data provide unique information on mass distribution and transport in the Earth System, linked to processes and changes in the Solid Earth, hydrology, cryosphere, oceans and atmosphere. Key applications of gravity data include geodetic studies (levelling and mapping), navigation (GPS/GLONASS) and satellite orbit planning.

Dr. Harsh Vardhan, further added that in addition to monitoring and forecasting of regular air quality and weather parameters, the ChandniChowk air quality station will also measure sun’s UV-Index and will provide measurement of online automatic ultrafine particles PM1 and Mercury, both of which have direct relevance to human health. Based on UVI, skin advisories will be issued on display. “Our mission model project SAFAR is implemented in four cities of India – Delhi, Pune, Mumbai and Ahmedabad as an operational service. Accordingto a preliminary economic assessment of the benefits of the system, if 5% of people suffering from air-pollution related diseases take advantage of the advisories and precautionsin Delhi alone, it would result in a saving of nearly Rs. 2,500 crores in terms of health-related cost benefit,” said Dr Harsh Vardhan, addressing a large gathering at Town Hall in ChandniChowk. The system will be an integral part of India’s first Air Quality Early Warning System operational in Delhi and will strengthen the existing air quality network of SAFAR, Central Pollution Control Board and Delhi Pollution Control Committee. SAFAR will accelerate public awareness and preparedness of air pollution and weather extremes. It will also lead to better understanding of linkages among emissions, weather, pollution and climate. It will monitor all weather parameters like temperature, rainfall, humidity, wind speed and wind direction. In addition to regular air quality parameters like PM2.5, PM10, Sulfur Dioxide, Ozone, Nitrogen Oxides, Carbon Monoxide, the system will also monitor the existence of Benzene, Toluene and Xylene. Besides health, SAFAR system would benefit cost savings to several other sectors like agriculture, aviation, infrastructure, disaster management skill, tourism and many others, which directly or indirectly get affected by air quality and weather.

It is a greenhouse gas mitigation technology which produces negative carbon dioxide emissions 2. BECSS works by involving the process of pyrogenic carbon capture and storage (PyCCS) or biochar Select the correct answer using the codes given below : A) Only 1 B) Only 2 C) Both are correct D) Both are incorrect Ans. A -Bio-energy with carbon capture and storage (BECCS) is a potential greenhouse gas mitigation technology which produces negative carbon dioxide emissions by combining bioenergy (energy from biomass) use with geologic carbon capture and storage.[1] The concept of BECCS is drawn from the integration of trees and crops, which extract carbon dioxide (CO2) from the atmosphere as they grow, the use of this biomass in processing industries or power plants, and the application of carbon capture and storage via CO2 injection into geological formations.[2] There are other non-BECCS forms of carbon dioxide removal and storage that include technologies such as biochar, carbon dioxide air captureand biomass burial[3] and enhanced weathering. According to a recent Biorecro report, there is 550 000 tonnes CO2/year in total BECCS capacity currently operating, divided between three different facilities (as of January 2012) In the IPCC Fourth Assessment Report by the Intergovernmental Panel on Climate Change (IPCC), BECCS was indicated as a key technology for reaching low carbon dioxide atmospheric concentration targets.[8] The negative emissions that can be produced by BECCS has been estimated by the Royal Society to be equivalent to a 50 to 150 ppmdecrease in global atmospheric carbon dioxide concentrations[9] and according to the International Energy Agency, the BLUE map climate change mitigation scenario calls for more than 2 gigatonnes of negative CO2 emissions per year with BECCS in 2050.[10] According to Stanford University, 10 gigatonnes is achievable by this date According to the OECD, “Achieving lower concentration targets (450 ppm) depends significantly on the use of BECCS”.[13] An alternative to BECSS is pyrogenic carbon capture and storage (PyCCS) or biochar.[14] Which are superior in order to fix carbon in a more stable way: solid C, for longer times. Carbon dioxide injected into geologic formations eventually leaks back into the atmosphere due to seismic activity and natural faults and problems with the seal of the ancient injection pits. Q.3 Which among the following is/are classified under the Third Generation Vaccines ? 1. DTP vaccine 2. DNA Vaccine 3. Polio Vaccine Select the correct answer using the codes given below : A) Only 3 B) 2 & 3 C) 1 & 2 D) Only 2 Ans. D DTP vaccine – Second generation Vaccine DNA Vaccine- Third generation Vaccine Polio Vaccine- First generation Vaccine DNA vaccination is a technique for protecting against disease by injection with genetically engineered DNA so cells directly produce an antigen, producing a protective immunological response. DNA vaccines have potential advantages over conventional vaccines, including the ability to induce a wider range of immune response types. Several DNA vaccines are available for veterinary use. Currently no DNA vaccines have been approved for human use. Research is investigating the approach for viral, bacterial and parasitic diseases in humans,  as well as for several cancers. Applications No DNA vaccines have been approved for human use in the United States. Few experimental trials have evoked a response strong enough to protect against disease and the technique’s usefulness remains to be proven in humans. A veterinary DNA vaccine to protect horses from West Nile virus has been approved. First-Generation Vaccines. Attenuated and inactivated vaccines are identified in the first generation, which use a primary method in their production. Attenuated pathogens, full organisms or inactivated bacterial toxin, which are effectively immunogenic, are used in making these vaccines. 2nd Generation Vaccines:- The second generation vaccines were created in order to minimize the risks of having the pathogen revert to a dangerous form. The way these vaccines work is that they do not contain the whole organism, but rather subunits. Subunits may consist of the toxins that the pathogen create (if they are bacterial). Another example of subunit vaccines are those that only contain protein sections of the pathogen, such as an acellular form. A great example of a 2nd generation vaccine is DTaP. The vaccine contains diptheria toxoid, tetanus toxoid, pertussis toxoid, as well as the acellular version of pertussis. As with the issues with the 1st generation of vaccines, the 2nd generation vaccines can generate antibody response and T-helper response, but AGAIN, no T-Killer response.
