Forest Survey of India  1981 Computer & Electronic   COMPUTER History ·         The earliest known tool for computation was the Abacus. It was developed in China. ·         Blaise Pascal invented the second real mechanical calculator called Pascaline. ·         Charles Babbage is considered as the 'father of computer' because he invented difference engine in 1822 and then analytical engine, which can store the information on punch cards, in 1837. ·         Alan Turing is regarded as father of 'modem computer' science.   Characteristics of Computer The characteristics of a computer are as follows: ·         Speed: The computer uses the electronic pulses, the speed of those pulses is virtually instantaneous and process the inputs in microseconds, nanoseconds or piccosenconds.   ·         Storage: It is also known as memory. It consists of computer components and recording media used to retain digital data.   ·         Accuracy: Computers are error free and most of the errors are due to human negligence.   ·         Versatility: Computers are multi-tasking in nature.   ·         Automation: It is a field where the computer itself executes all tasks automatically when inputs are provided to it.   Limitations of a Computer ·         No Self Intelligence: Though a computer is programmed to work efficiently, fast and accurately, yet it is programmed by human beings to do so.   ·         Decision Making: The concept of artificial intelligence shows that the computer is the decision maker. But it is still dependent on instructions provided by human being.   ·         Self Care: Computer cannot take care of itself like a human being. It is dependent on human beings for this purpose.   ·         Retrieval of Memory: Computers can retrieve data very fast but this technique is linear. Human mind does not follow this rule.   ·         Sensation: Computers cannot feel like a human being.   Generations of Computer First Generation (Vacuum Tube) 1940-56 ·         Technology: Use of vacuum tubes in electronic circuit ·         Internal Operating Speed (IOS): Milliseconds ·         Operating Systems (OS): Batch processing ·         Languages: Machine code and electric boards ·         Examples: UNIVAC-I, IBM-701   Second Generation (Transistor) 1957-63 ·         Technology: Use of transistor and diodes ·         IOS: Microseconds ·         OS: Batch processing ·         Languages: Assembly language, high more...
  Biotechnology and Genetics   ·                     Biotechnology, generally speaking, is any technique that is used to make or modify the products of living organisms in order to improve plants or animal or to develop useful microorganisms. ·                     In modem terms, biotechnology has come to mean the use of cell and tissue culture, cell fusion, molecular biology, and in particular, recombinant deoxyribonucleic acid (DNA) technology to generate unique organisms with new trait or organisms that have the potential to produce specific products. ·                     The origin of biotechnology can be traced back to prehistoric times, when microorganisms were already used for processes like fermentation. Although a molecular biologist may consider cloning of DNA to be the most important event in the history of biotechnology, the latter has actually been rediscovered in 1970s for the third time during the last century. ·                     In 1920s, Clostridium acetobutylicum was used by Chaim Weizmann for converting starch into butanol and acetone; the latter was an essential component of explosives during World War I. This raised hopes for commercial production of useful chemicals through biological processes, and may be considered as the first rediscovery of biotechnology in the last century. ·                     Similarly, during World War II (in 1940s), the production of penicillin (as an antibiotic discovered by Alexander Flemming in 1929) on a large scale from cultures of Penicillium notatum, marked the second rediscovery of biotechnology. This was the beginning of an era of antibiotic research. ·                     The third rediscovery of biotechnology is its recent reincarnation in the form of recombinant - DNA technology, which led to the development of a variety of gene technologies and is thus considered to be the greatest scientific evolution of the last century. ·                     Although the term sounds contemporary, biotechnology is not new Over 9,000 years ago, people discovered that microorganisms could be used to make bread, brew alcohol, and produce cheese. Although this process of fermentation was not thoroughly understood at that time, its use still constitutes a traditional application of biotechnology ·                     What is new, however, is the extent of applications and sophistication of biotechnology techniques currently employed. Researchers car manipulate living organisms and transfer genetic material between organisms. Genetic engineering, the specific modification or transfer of genetic material, underlies modem biotechnological innovations These current applications of biotechnology are predominantly practised in the fields of agriculture and medicine. Modem technique- allow for the production of new and improved foods. Virus resistant crop plants and animals have been developed and advances in insect resistance have been made. Biotechnology applications vaccines for malaria, and improved ways of producing insulin. Diagnostic tests for detecting serious diseases such as hereditary cancers and Huntington's chorea have been developed as well more...

  Energy (Renewable and Non ? Renewable)   GENERAL INTRODUCTION Power development in India dates back to the pre-Independence era with the commissioning of electricity supply in Darjeeling during 1897. It was followed by the commissioning of a hydro power station at Sivasamudram in Karnataka during 1902. Through private sector controlled power supply in the pre Independence era, formation of state electricity boards during Five- Year Plans and setting up of multipurpose projects with thermal, hydro and nuclear power stations systematic growth of power supply industry in the country took place. India is the fifth largest producer and consumer of electricity in the world. It produces 1,006 Terawatt Hours (TWh) of power which has grown at a compound annual growth rate (CAGR) of 5.5 per cent. The Indian power sector is one of the most diversified sectors in the world. The generation of power in India is done using main commercial sources like coal, lignite, natural gas, oil, hydro and nuclear power. Other viable non- conventional sources include wind, solar, agriculture and domestic waste. The Government of India targeted capacity addition of 89 GW under the 12th Five-Year Plan (2012-17). It plans to add close to 100 GW under the 13th Five-Year Plan (2017-22). Investments of around US$ 223.9 billion have been planned for the power sector during the 12th Five-Year Plan (2012-17). There is a target of generating 10,000 MW of power through solar energy by 2017. Phase I of the Jawaharlal Nehru National Solar Mission has been very successful, wherein 1,685 MW of solar power was generated. The government of India has permitted an FDI up to 100 per cent under the automatic route for the projects of electricity generation (except atomic energy), transmission distribution and power trading. The Ministry of Power (MOP) is the nodal authority for the development of power resources in the country. The Central Electricity Authority (CEA) assists the Ministry in technical matters. An Electricity Policy was developed by the ministry which sets the tune for generation of electricity in the country.   (1) Energy Sector in India By and large, the Indian energy sector has been regulated and owned by government agencies and organisations, though of late the entry of private sector has enhanced the scope for greater power generation.   (2) Institutional Structure The basic institutional structure comprises of a nodal ministry at the centre for each energy supply sector, which is the primary agency for policy formulation support in decision-making, and implementation by state governments; state- level nodal agencies, public sector undertakings, and technical and research institutions. The Union Government plays a dominant role in the energy sector and it is mainly due to the fact that the subject energy has been placed in the concurrent list of the Seventh Schedule of the Constitution of India.   (3) India's Energy Policy The Energy Policy of India speaks about the goals with respect to short medium and long terms, which are as follows: ·         more...

PASSAGE ON YOGA   Spirituality is not a path for the weak-hearted. Swami Vivekananda has said, I need lions and not sheep." He said so because spirituality is a platform where one has to constantly work on oneself. Every moment we work on ourselves to make sure we reach the ultimate aim of enlightenment. It's a journey that we take from what we are for the outside world to what we are really inside.   The journey can be started only after the rite of initiation is over. And when it comes to spiritual realm, this rite of initiation is in the form of the five fundamental qualities that is espoused by Patanjali under the step of yama'. The primary elements of Patanjali's Astanga Yoga, starting with yama, niyama etc., can be better appreciated and actually realised by a few moments of daily meditation.   The word yama5 has different connotations and meanings. . In Sanskrit, it means 'regulation' or 'self-discipline', yama means to give up. It is actually giving up one's desires, and all passions other than the passion for spiritual enlightenment. It is disciplining one's mind and body so that it becomes strong and pure enough to take in the whole of spiritual truth.   In Hindu mythology, Yama is the god of death. How is the god of death connected to the very first step of spirituality? The answer lies in the right understanding of life itself. The ending and beginning of life is all subjective. The beginning is when the soul gets attached and the end is when the soul withdraws itself.   The real secret is to die when you are still alive. You have to go beyond your attachments and aspirations of your present self and control your inner desires to realize what you really are. Meditation is also called a process of conscious annihilation. But people get sacred when they go deep into meditation, and they open their eyes immediately. They are unaware of the real goal and are thus scared.   Live as if you are going to die the next moment. Though it sounds negative in the beginning, there is a deep wisdom conveyed in the whole idea. This idea of the living dead is nothing but transcending one's ego with love. And this in turn removes all the restriction that was being placed in one's spiritual journey, thus leading to spiritual enlightenment.   PRECIS   YAMA-THE FIRST STEP TO SPIRITUALITY   Spirituality suits people who are strong-minded since it requires constant self-analysis. It's a path that begins with rationality and ends in consciousness. This journey can begin only after the the follower is initiated into the five qualities mentioned by Patanjali, that starts with Yama. niyama etc. Yama is disciplining oneself, and to purify one's mind. Yama is the cessation of attachment to life which can only take more...
1. Essay Writing   ANYONE CAN WRITE AN ESSAY!  Surprised? Don't be. With the right tools and average level of content, anyone can write an essay. And that's what we are going to give you-   THE RIGHT TOOLS   Before writing an essay, you need to know what an essay is, and what it isn't. Essay is not an illogical arrangement of ideas. It's not a haphazard array of sentences. It is a flow of ideas with a single idea- as the backbone; the other ideas complementing this single idea. And these set of ideas when set in a proper structure become a good essay. All essays might look the same to an untrained eye, but they're not. There are different types of essays, according to the way in which the writer deals with the topic at hand. They are:"  
  • Personal
  • Narrative
  • Descriptive
  • Expository
  • Analytic
  • Persuasive
  • Argumentative
  •   PERSONAL ESSAYS Personal essays are what one may call writing from the heart. They have a personal touch and are often written in a conversational manner, and may be called an autobiographical non-fiction.   NARRATIVE ESSAYS Narrative essays can be said to be closely related to personal essays in which we write from first person perspective. These are narrations of an event or a situation, generally a real-life experience.   DESCRIPTIVE ESSAYS Descriptive essays are closely related to narrative essays, but differentiated by the absence of first person perspective ('I'). These are descriptions of a person, place, object or even memory of special significance. Expository essays are essays completely separated from the above-given types in that they completely avoid any reference to personal feelings. They are fully based on factual knowledge, and present the conclusion on the basis of facts, statistics and examples.   ANALYTICAL ESSAYS Analytical essays are a type of expository essays with personal analysis in addition. In this, the writer analyses the given data and presents a balanced view in the conclusion. Persuasive essays are analytical essays with a strong emphasis on one's viewpoint, so as to persuade the reader to accept the writer's point of view or recommendation.   ARGUMENTATIVE ESSAYS Argumentative essays are a stronger form of persuasive essays, but they differ in the fact that in it, the author presents his view in contrast to the other viewpoints that exist, while in persuasive essays, the author just gives his own viewpoint in the attempt to persuade. According to the topic and the context in which one is writing the essay, one can decide which type of essay one wants to write. How to write an essay? Now that we have dealt with the description and types of essay, we come to the most important part-how to write an essay. All essays should have three parts-
  • Introduction,
  • Content, and
  • Conclusion
  •   INTRODUCTION Introduction is the part where one initiates the topic. It is an insight into what the writer is going to write in the following passages. While it should have more...
