APPSC Group 1 Mains 2008 GENERAL ENGLISH Paper
What is genome mapping? What are the advantages and disadvantages of Human Genome Mapping?
Human Genome refers to the entire genetic make up of human beings and every human cell contains around 4000 genes. The Human Genome project is an international research programme deigned to construct detailed genetic and physical maps of the human genome to determine the complete nucleotide sequence of human DNA, to localize the estimated 50,000-1, 00,000 genes with the human genome and to perform similar analysis on the genomes of several other organism used extensively in research laboratories as model systems.
The scientific products of human Genome project will comprise a resource of detailed information about the structure, organization and function of Human DNA, information that constitutes the basic set of inherited "instructions" for the development and functioning of human being. The Human Genome project was conceived in the mid-1980s and was widely discussed within the scientific communicating and public press.
Advantages
a) In the field of molecular - medicine it will help to improve diagnosis of diseases, early detection of genetic diseases and gene therapy. Genetic has also the potential to reveal the differences between the individuals so that suitable treatment can be prescribed and national drug design can be undertaken. Thus treatment can be more focused and effective based on individual requirement.
b) DNA forensics can be used in identifying war victim's particularly dead soldiers whose bodies are mutilated beyond recognition. It can provide full proof results in ascertaining disputed parentage, criminal justice can be more effective with the help of DNA forensics and people who commit murder of rape can be provided with evidences against them.
c) In the field of agriculture and livestock breeding understanding of plant and animal genome will help us to create stronger and more .disease resistant plant and animals. It will also help in the development of bio pesticide and edible vaccines incorporated into food products.
Disadvantages of HGP
(i) It may lead to parents attempting to determine which character their off spring shall inherit. This will lead to the development of designer baby.
(ii) This may restrict the human gene pool and interface with natural selection and loss of diversity among the human population.
(iii) Misuse of genetic information may violate genetic privacy Also health or life insurance policies may be deemed to an individual on the basis of his genetic information
(iv) It can be misused for developing weapon of mass destruction.
(v) It could also develop racial discrimination.
(vi) The success of HGP may widen the gap between developed and developing, as only the rich countries alone would be able to enjoying the advance medical treatment.

Types of Conventional and Non Conventional sources of energy
Conventional : Energy that has been used from ancient times is known as conventional energy. Coal, natural gas, oil, and firewood are examples of conventional energy sources. (or usual) sources of energy (electricity) are coal, oil, wood, peat, uranium.
Non-conventional (or unusual) sources of energy include:
• Solar power
• Hydro-electric power (dams in rivers)
• Wind power
• Tidal power
• Ocean wave power
• Geothermal power (heat from deep under the ground)
• Ocean thermal power (the difference in heat between shallow and deep water)
• Biomass (burning of vegetation to stop it producing methane)
• Biofuel (producing ethanol (petroleum) from plants

Biomass as alternative technologies
Biomass
Solid biomass
Plants use photosynthesis to store solar energy in the form of chemical energy.The easiest way to release this energy is by burning the dried up plants. Solid biomass such as firewood or combustible field crops including dried manure is usually burnt to heat water and to drive turbines. Field crops may be grown specifically for combustion or may be for other purposes and the processed plant waste then used for combustion.Most sort of biomass including sugarcane residue, wheat chaff, corn cobs and other plant matter can be, and is, burnt quiet successfully. Currently biomass contributes 15% of total energy supply world wide.
A drawback is that all these biomass needs to go through some of these steps: It needs to be grown, collected, dried and fermeneted and burned. All of these steps require resources and an infrastructure.
Bio-fuel
Bio-fuel is any fuel that derives from biomass- recently living organisms or their metabolic byproducts, such as manure from cows. Typically bio-fuel is burnt to release it's stored chemical energy. Biomass, can be directly used as fuel or to produce liquid biofuel. Agriculturally produced biomass fuels, such as biodiesel, ethanol and bagasse(often byproduct of sugarcane cultivation) can be burnt in internal combustion engines or boilers.
Biogas
Biogas can easily be produced from current waste streams,such as paper production, sugarcane production, sewage, animal waste and so forth. The various waste streams have to be slurred together and allowed to naturally ferment, producing 55% to 70% inflammable methane gas. Biogas production has the capacity to provide us with about half of our energy needs, either burned for electrical productions or piped into current gas line for use. This has to be done and made a priority. The payback period of biogas is around 2-3 years, rather in case of community and institutional Biogas plant is even less. Therefore biogas electrification at community level is required to be implemented.

Geothermal energy
Geothermal Energy
Geothermal energy is very clean source of power. It comes from radioactive decay in the core of the Earth, which heats the Earth from inside out and thus energy/power can be extracted owing to the temperarture difference between hot rock deep in the earth and relatively cool surface air or water. This requires that the hot rock be relatively shallow, so it is site-specific and can only be applied in geologically active areas.
It can be used in two ways
• Geothermal heating
• Geothermal electricity
As stated above, geothermal energy from the core of the earth is closer to surface in some area than in others. Where hot underground steam or water can be tapped and brought to the surface it may be directly used to heat or cool buildings or indirectly used to generate electricity by running steam turbines. Even otherwise, on most of the globe, the temperature of the crust few feet below the surface is buffered at a constant 7-14 degree Celsius, so liquid can be pre-heated or pre-cooled in underground pipelines, providing free cooling in the summer and heating in the winter by using heat pumps.

Nuclear / radioactive waste disposal techniques
Long-term storage on land seems to be the favorite of most countries.
a) Disposal of Nuclear Waste in Space
Outer space is the most appropriate long-term storage option for high-level nuclear waste. This would ensure it's safe removal from humans regardless of the activities of nature or man on earth. Anybody accidentally stumbling upon this waste would be at a lesser risk as they would be using radioactive shielding for space travel. Delivery of the waste into space has a crippling drawback -- the rocket used to deliver the waste into space would need to provide enough power to escape the earth's gravity. This is necessary for two reasons: a) to leave the waste in orbit creates space garbage that is likely to reenter the earth's environment at some time due to collision with satellites and other orbiting waste or spacecraft; and b) the large delivery rocket would be expensive and an accident during launch could have catastrophic results. Space disposal therefore, will not be a viable option until space travel is considerably safer and less expensive.
b) Storage of Radioactive Waste in the Sea Bed
A possibility for long-term storage on the earth is burial in the seabed. The rock formations in the seabed are generally more stable than those on land reducing the risk of exposure due to seismic activity. Apart from this, there is little groundwater circulation under the seabed, reducing the possibility of radioactive material contaminating ground water available for human consumption. The greatest appeal of under sea burial is also its greatest drawback. The enormous cost and difficulty of excavating the waste would likely prevent accidental or malicious disturbing of the waste. This cost is also keeping us from burying the waste at sea.
c) Long Term Storage of Radioactive Waste on Land
Long term storage in tectonically stable rock formations on land is the most likely solution for high-level radioactive waste. The radioactive material may be vitrified1 and buried in caverns, created in a large rock formation. When use of the storage area is complete, it would be sealed again with stone. While still extremely expensive, and considerably unsafe, this is the most viable storage option currently available. Using methods that reduce the amount of radioactive waste could further enhance safety levels.

Types of radioactive wastes
Exempt waste & very low level waste
Exempt waste and very low level waste (VLLW) contains radioactive materials at a level which is not considered harmful to people or the surrounding environment. It consists mainly of demolished material (such as concrete, plaster, bricks, metal, valves, piping etc) produced during rehabilitation or dismantling operations on nuclear industrial sites. Other industries, such as food processing, chemical, steel etc also produce VLLW as a result of the concentration of natural radioactivity present in certain minerals used in their manufacturing processes (see also information page on Naturally-Occurring Radioactive Materials). The waste is therefore disposed of with domestic refuse, although countries such as France are currently developing facilities to store VLLW in specifically designed VLLW disposal facilities.
Low-level waste
Low-level waste (LLW) is generated from hospitals and industry, as well as the nuclear fuel cycle. It comprises paper, rags, tools, clothing, filters etc, which contain small amounts of mostly short-lived radioactivity. It does not require shielding during handling and transport and is suitable for shallow land burial. To reduce its volume, it is often compacted or incinerated before disposal. It comprises some 90% of the volume but only 1% of the radioactivity of all radioactive waste.
Intermediate-level waste
Intermediate-level waste (ILW) contains higher amounts of radioactivity and some requires shielding. It typically comprises resins, chemical sludges and metal fuel cladding, as well as contaminated materials from reactor decommissioning. Smaller items and any non-solids may be solidified in concrete or bitumen for disposal. It makes up some 7% of the volume and has 4% of the radioactivity of all radwaste.
High-level waste
High-level waste (HLW) arises from the 'burning' of uranium fuel in a nuclear reactor. HLW contains the fission products and transuranic elements generated in the reactor core. It is highly radioactive and hot, so requires cooling and shielding. It can be considered as the 'ash' from 'burning' uranium. HLW accounts for over 95% of the total radioactivity produced in the process of electricity generation. There are two distinct kinds of HLW:
- Used fuel itself.
- Separated waste from reprocessing the used fuel.
HLW has both long-lived and short-lived components, depending on the length of time it will take for the radioactivity of particular radionuclides to decrease to levels that are considered no longer hazardous for people and the surrounding environment. If generally short-lived fission products can be separated from long-lived actinides, this distinction becomes important in management and disposal of HLW.

Difference between nuclear fission and fusion
Nuclear Fission | Nuclear Fusion | |
Definition: | Fission is the splitting of a large atom into two or more smaller ones. | Fusion is the fusing of two or more lighter atoms into a larger one. |
Natural occurrence of the process: | Fission reaction does not normally occur in nature. | Fusion occurs in stars, such as the sun. |
Byproducts of the reaction: | Fission produces many highly radioactive particles. | Few radioactive particles are produced by fusion reaction, but if a fission "trigger" is used, radioactive particles will result from that. |
Conditions: | Critical mass of the substance and high-speed neutrons are required. | High density, high temperature environment is required. |
Energy Requirement: | Takes little energy to split two atoms in a fission reaction. | Extremely high energy is required to bring two or more protons close enough that nuclear forces overcome their electrostatic repulsion. |
Energy Released: | The energy released by fission is a million times greater than that released in chemical reactions; but lower than the energy released by nuclear fusion. | The energy released by fusion is three to four times greater than the energy released by fission. |
What is the Purpose of using Heavy Water in Nuclear Reactor?
