An Introduction To Nanoscience And Nanotechnology Biology Essay The word nanotechnology is an umbrella term and it accommodates conventional natural philosophies, biological science, chemical science, stuffs scientific discipline and full scope of technology subjects. Nanotechnology is an wholly new construct in fabrication that will do most merchandises lighter, stronger, cleaner, less expensive and more precise. Nanotechnology will deeply impact economic system and society, much as the industrial revolution has. Over the past few old ages, we have witnessed rapid progresss in the field of nanotechnology on many foreparts including stuffs and fabrication, nano-electronics, medical specialty and health care, energy, biotechnology and information engineering. These progresss have led to the handiness of an array of engineerings for possible applications. Applications of nanotechnology during the following few decennaries could bring forth immense addition in computing machine velocity and storage capacity, efficient lighting and battery storage, d ecrease in the cost of desalting H2O, apparels that neer discoloration and glass that neer needs cleansing and therapies for different types of complaints. Technology in the 20 first century demands the miniaturisation of devices into nanometer sizes while their public presentation is surprisingly enhanced. It is widely felt that nanotechnology will be the following industrial revolution. The nanotechnology merchandises, stuffs and their applications are still in developing phase and true revolution is old ages off, it can be a few or many old ages. This engineering aims tinier and faster alternatively of bigger and slower. Therefore, nanotechnology provides entree to the universe of the smallest things. While the benefits are about illimitable, they will be realized merely if the inauspicious effects of nanotechnology are studied and managed. Outline1 1.1 Definition2 1.2 The Significance of the Nanoscale3 1.3 History of Nanotechnology4 1.3.1 Moore s Law5 Moore s Law Equation:6 .7 1.4 Applications8 1.4.1 Medicine9 1.4.2 Nanoelectronics10 1.4.3 Batteries11 1.4.4 Environmental Protection12 1.4.5 Agribusiness13 1.4.6 Energy14 1.4.7 Nano products/devices15 1.5 Hazards of Nanomaterials16 Further Reading 1.1 Definition The nano in nanotechnology comes from the Greek word nanos which means midget, refers to a decrease of size by 10-9 m. A nanometre ( nm ) equals 10-9 metre. To make a sense of nano scaled objects, one human hair is about 80,000 nanometres thick ; a caput of a pin is about a million nanometres broad ; an atom is about 1 nm broad ; a Deoxyribonucleic acid molecule is about 2.5 nanometers broad and a ruddy blood cell is about 5,000 nanometers in diameter. A nanoelement can be compared to a hoops, like a hoops to the size of the Earth. Figure 1.1 illustrates the differences in graduated table that ranges from human all the manner down to one atom. The figure besides shows appropriate tools and theoretical accounts for the survey of objects at assorted sizes. Atoms are the edifice blocks of stuffs and the belongingss of the stuffs can be tuned by the agreement of atoms. Merely through the usage of powerful microscopes, scientists can see and pull strings nano-sized atoms. It is appro priate to call the nanometre graduated table the Feynman ( IÃ¢â¬ nman ) graduated table after Feynman s great parts to nanotechnology. 1 Feynman = 1 Nanometer = 10-9 metre =10-3 Micron =10 Angstroms Nanoscience involves researches to detect new behaviors and belongingss of stuffs with dimensions at nanoscale, which ranges approximately from 1 to 100 nanometres. Nanotechnology is the research and development of stuffs, devices and systems by commanding form and size at the nanometer graduated table with at least one fresh belongings. The United States National Science Foundation defines nanoscience or nanotechnology as surveies that deal with stuffs and systems holding the undermentioned key belongingss: ( I ) Dimension at least one dimension from 1 to 100 nanometres, ( two ) Process designed with methodological analysiss that shows cardinal control over the physical and chemical properties of molecular-scale constructions, and ( three ) Building block belongings they can be combined to organize larger constructions. The national nanotechnology enterprise of NSF defines nanotechnology as the apprehension and control of affair at dimensions of approximately 1 to 100 nanometres , where alone phenomena enable novel applications . In short, nanotechnology is the ability to construct micro and macro stuffs and merchandises with atomic preciseness. 1.2 The Significance of the Nanoscale The promise and kernel of the nanoscale scientific discipline and engineering is based on the fact that stuffs at the nanoscale have belongingss ( i.e. chemical, electrical, magnetic, mechanical and optical ) rather different from the majority stuffs. Some of such belongingss are intermediate between belongingss of the smallest elements from which they can be composed of and those of the macroscopic stuffs. Compared to bulk stuffs, nanoparticles possess enhanced public presentation belongingss when they are used in similar applications. Surface morphology, surface to volume ratio and electronic belongingss of stuffs could alter appreciably due to particle size alterations. Complexs made from nanoparticles of ceramics or metals can all of a sudden go much stronger than that predicted by bing stuffs scientific discipline theoretical accounts. For illustration, metals with a so called grain size of around 10 nanometres are every bit much as seven times harder and tougher than their ordi nary opposite numbers with grain sizes in the 100s of nanometres. Fig. 1.1: Scale of things Nanoscale is a charming point on the dimensional graduated table. Structures in nanoscale ( called nanostructures ) are considered as the boundary line of the smallest of adult male made devices and the largest molecules of populating systems. The ability to command and pull strings nanostructures will do it possible to work new physical, biological and chemical belongingss of systems. There are many specific grounds why nanoscale has become so of import, some of which are as the followers: ( I ) The quantum mechanical effects come into drama at really little dimensions. By planing stuffs at the nanoscale, it is possible to change the cardinal belongingss of stuffs, such as electrical, optical, mechanical and magnetic without altering their chemical composing. ( two ) Nanodevices with bio-recognition belongingss provide tools at nanoscale, which offers a enormous chance to analyze biochemical procedures and to pull strings life cells at individual molecule degree. The synergistic hereafter of nanotechnologies hold great promise for farther promotion in tissue technology, prosthetic devices, pharmacogenomics, surgery and general medical specialty. Nanoscale constituents have really high surface to volume ratio, doing them ideal for usage in composite stuffs, responding systems, drug bringing and chemical energy storage. Since atom is really near to the surface or interface, behavior of atoms at these higher-energy sites have a important influence on the belongingss of the stuff. For illustration, the responsiveness of a metal accelerator atom by and large increases appreciably as its size is reduced. It is interesting that macroscopic gold is chemically inert, whereas at nanoscales gilded becomes highly reactive and catalytic, and even thaws at a lower temperature. The larger surface country allows more chemicals to interact with the accelerator at the same time, which makes the accelerator more effectual. Macroscopic systems made up of nanostructures can hold much higher denseness than those made up of microstructures. They can besides be better music directors of electricity. This can ensue in new electronic device constructs, smaller and faster circuits, more sophisticated maps and greatly decreased power ingestion. The new coevalss of scientific tools that operate in nanoscale enable to roll up informations and to pull strings atoms and molecules on a really little graduated table. With these tools, it is found that many familiar stuffs act otherwise and have different features and belongingss when they are in nanoscale measures. Furthermore, stuffs at the nanoscale can exhibit surprising features that are non seen at big graduated tables. For case: Carbon in the signifier of black lead ( like pencil lead ) is soft and ductile ; at the nano-scale, C can be stronger than steel and is six times lighter. Besides, C atoms in the signifier of a nanotube exhibit tensile strength 100 times than that of steel. Collections of gold atoms can look orange, purple, ruddy or light-green, depending upon the specific size of the atoms doing up the sample. Zinc oxide is normally white and opaque ; nevertheless, at the nano-scale it becomes crystalline. Aluminum can spontaneously burn at the nano-scale and could be used in projectile fuel. Nano-scale Cu becomes a extremely elastic metal at room temperature. It can be stretch up to 50 times its original length without interrupting. Research workers hope to copy nature s secrets of edifice from the nanoscale, to make procedures and machinery. They have already copied the nanostructure of Nelumbo nucifera foliages to make H2O repellant surfaces, being used to do stain free vesture and stuffs. Human organic structures and those of all animate beings use natural nanoscale stuffs, such as proteins and other molecules, to command many systems and processes in it. A typical protein, hemoglobin, which carries O through the blood stream, is 5 nanometres in diameter. That is, many of import maps of life beings take topographic point at the nanoscale. 1.3 History of Nanotechnology Worlds have inadvertently employed nanotechnology for 1000s of old ages, but it is non clear when they foremost began to utilize the advantage of nanophase stuffs. In the 4th century Roman glass workers were manufacturing spectacless incorporating nano metals. A cup, called Lycurgus cup ( depicts the decease of King Lycurgus ) made during this period is exhibited at the British Museum in London. This is made from soda lime glass incorporating Ag and gold nanoparticles. The coloring material of the cup alterations from green to red when a beginning of visible radiation is placed inside it. The beautiful colors of the Windowss of medieval churches are besides due to the presence of metal nanoparticles in the glass. During the tenth century, nanoscale gold was used in stained glass and ceramics. In 1661, Irish chemist Robert Boyle questioned Aristotle s belief that affair is composed of Earth, fire, H2O and air. He suggested that bantam atoms of affair combine in assorted ways to organize atoms. Michael Faraday published a paper in the Philosophical Transactions of the Royal Society in 1857, which explained how metal atoms affect the coloring material of glass Windowss of churches. In German diary Annalen der Physik ( 1908 ) , Gustav Mie reported an account of the dependance of the coloring material of the spectacless on metal size. James Clerk Maxwell in 1867 mentioned some of the separating constructs in nanotechnology and proposed a bantam entity known as Maxwell s Demon . He besides produced the first coloring material exposure that depends on production of Ag nanoparticles sensitive to visible radiation in 1861. Chemical contact action is an illustration of old nanotechnology . Today, accelerators speed up 1000s of chemical transmutations like those that convert petroleum oil into gasolene, little organic chemicals into life-saving drugs and polymers, and inexpensive black lead into man-made diamond for doing industrial film editing tools. Most accelerators were discovered by test and mistake by shaking and baking metals and ceramics, and so seeing how the consequence affects the reactions and their merchandises. Emersons Philosofy Essay1.4.4 Environmental Protection Nanotechnology has the possible to profit the environment through pollution intervention and redress as any waste atoms could be recycled, since they could be kept under control. This would include improved sensing and detection, remotion of the finest contaminations from air, H2O and dirt, and creative activity of new industrial procedures that cut down waste merchandises and are ecofriendly. Airborne nanorobots could be programmed to reconstruct the thinning ozone bed. Immense tunnage of extra C dioxide in the ambiance could be economically removed air bone. One of the biggest environmental challenges that humanity faces today is clean H2O. The possible benefits of nanotechnology besides help to take the finest contaminations from H2O and air, advancing a cleansing agent environment and drinkable H2O at an low-cost cost. Nanoparticles of Fe can be effectual in the killing of chemicals in groundwater because they react more expeditiously to those chemicals than larger Fe atoms. 1.4.5 Agribusiness Nanotechnology will better agricultural outputs for an increased population, supply more economical H2O filtration and desalinization, and better renewable energy beginnings, such as solar energy transition. Nanotechnology has a important consequence in the chief countries of the nutrient industry: development of new functional stuffs, merchandise development and design of methods and instrumentality for nutrient safety and bio-security. Using nanoparticle engineering, Bayer has developed an air-tight plastic packaging that will maintain nutrient freshman and longer than their old plastics. Nanotechnology will besides assist to modify the familial fundamental law of the harvest workss, thereby assisting betterment of harvest workss. Nanotechnology based works disease nosologies help to observe exact strain of virus and phase of application of some curative to halt the disease. 1.4.6 Energy Energy applications of nanotechnology include storage, transition, fabricating betterments by cut downing stuffs and procedure rates, energy economy and enhanced renewable energy beginnings. Nanotechnology could assist increase the efficiency of light transition of solar cells by utilizing nanostructures with a continuum of set spreads. Nanotechnological attacks like light-emitting rectifying tubes ( LEDs ) or quantum caged atoms ( QCAs ) could take to a strong decrease of energy ingestion for light. An environmental friendly signifier of energy is the usage of fuel cells powered by H. The most outstanding nanostructured stuff in fuel cells is the accelerator dwelling of C supported baronial metal atoms with diameters of 1-5 nanometer. Suitable stuffs for H storage contain a big figure of little nanosized pores. Therefore many nanostructured stuffs like nanotubes, zeolites or alanates are under probe. 1.4.7 Nano products/devices The ability to see nano-sized stuffs has opened up a universe of possibilities in a assortment of industries and scientific enterprises. As mentioned earlier, nanotechnology is basically a set of techniques that allow use of belongingss at a really little graduated table and it may assist to revolutionise merchandises everyplace, making a huge array of new merchandises and devices. The promise of these merchandises and devices is enormous. Nanotechnology can alter the nature of about every manufactured merchandise. Because of this, nanotechnology will hold more influence than the Si integrated circuit, medical imagination, or computer-aided technology. Amazingly, more than 1000 commercial nanomaterial-based merchandises are available in the market. The belongingss of familiar stuffs are being changed by makers who are adding nano-sized constituents to conventional stuffs to better public presentation. For illustration, some vesture makers are doing H2O and discoloration repellant dressing utilizing nano-sized beards in the cloth that cause H2O to bead up on the surface. Companies are now fabricating nanoparticles for usage in 100s of commercial merchandises from crack-resistant pigments and stain-resistant vesture, to self cleansing Windowss and anti-graffiti coatings for walls. Some illustrations of nano products/devices: Exploiting the anti-bacterial belongingss of nano-scale Ag, Smith A ; Nephew developed wound dressings ( patchs ) coated with silver nano-crystals designed to forestall infection. Hundreds of merchandises integrating nanosilver are now on the market, including sheets, towels, contraptions, socks, toothbrushes, toothpastes and kids s playthings. Nanoparticles of Ti dioxide ( TiO2 ) are crystalline and block UV ( UV ) visible radiation. Nano-scale TiO2 is now being used in sunblocks and in clear plastic nutrient wraps for UV protection. Nano-scale atoms of hydroxyapatite have the same chemical construction as tooth enamel. Research workers at BASF are trusting to integrate the nanoparticles in toothpaste to construct enamel-like coating on dentitions and to forestall bacteriums from perforating. Sangi Co. Ltd. ( Japan ) has been selling a toothpaste incorporating nano-hydroxyapatite since 1980. Nano-Tex sells Stain Defender for khaki bloomerss and other cloths a molecular coating that adheres to cotton fibre, organizing an impenetrable barrier that causes liquids to bead and turn over off. Pilkington sells a self-cleaning window glass covered with a surface bed of nano-scale Ti dioxide atoms. When the atoms interact with UV beams from sunshine, the soil on the surface of the glass is loosened, rinsing off when it rains. BASF sells nano-scale man-made carotenoids as a nutrient additive in lemonade, fruit juices and oleo ( carotenoids are antioxidants and can be converted to Vitamin A in the organic structure ) . Harmonizing to BASF, carotenoids formulated at the nano-scale are more easy absorbed by the organic structure and besides increase merchandise shelf life. Syngenta, the universe s largest agrochemical corporation, sells two pesticide merchandises incorporating nano-scale active ingredients. The company claims that the highly little atom size prevents spray armored combat vehicle filters from choke offing and the chemical is readily absorbed into the works s systems and can non be washed off by rain or irrigation. Altair Nanotechnologies is developing a water-cleaning merchandise for swimming pools and fishponds. It incorporates nano-scale atoms of a lanthanum-based compound that absorbs phosphates from the H2O and prevents algae growing. Silicon-based, disposable blood-pressure detector french friess were introduced in the early 1990s by NovaSensor for blood force per unit area monitoring. A assortment of biosensors are manufactured by assorted companies, including ACLARA, Agilent Technologies, Calipertech, and I-STAT. 1.5 Hazards of Nanomaterials Although nanotechnology has a important impact on society, and every sector of economic system, nanomaterials may present new hazards to workers, consumers, public and environment. Hazards can happen anyplace nanomaterials come in contact with people, animate beings or environment. Key hazards relate to liability, privateness, funding and safety of merchandises. For the wellness sphere, the most immediate concerns are likely the safe and ethical usage of nanomaterials. The microscopic size of nanoparticles makes them hard to be detected and controlled. Research workers, staff, consumers or patients may unwittingly inhale curative merchandises. The theoretical accounts and predictability of these molecular interactions are non yet known. Therefore, safeguards to avoid inspiration and exigency methods to disenable the engineering will be needed. Current baseball mitts, masks, and gowns may non supply equal protection, making a demand for new rating research, new protective equipment, a nd a computation of the associated costs before the engineering is widely used. Merely a few research findings are available about the safety of nanomaterials. Research workers found that nanoparticles can arouse increased inflammatory responses and potentiate the consequence of medicines. Peoples have started to raise serious inquiries about the possible impact of nanomaterials on human wellness. The little size of nanoparticles can give them greater entree to organic structure tissues and variety meats than larger particulates. Animal surveies have reported that some inhaled nanomaterials pass easy from the nose straight into the encephalon via olfactive nerve cells, and from lungs into the blood watercourse. Once nanomaterials enter the organic structure, the larger surface country of nanomaterials per unit of mass makes them more chemically reactive than their normal-scale opposite numbers, and hence more likely to interact with biological molecules. Cell surveies indicate that some nanomaterials may interact with cell DNA, cause redness and oxidative harm, and impair cell map. Engineered alterations to nanomaterials, such as surface coatings, can change a stuff s solubility, chemical activity, toxicity, and other belongingss, supplying an chance to cut down the ha zards associated with a material early in its design. Although there is a dearth of toxicity informations particular to engineered nanomaterials, the jeopardies of nanosize air pollutants are good documented. Particulate affair less than 10I?m ( 10,000 nanometer ) has been linked to increased lung malignant neoplastic disease and cardiorespiratory disease. While all particulate air pollution is risky, smaller inhaled atoms have long been known to be more detrimental to organic structure tissues than larger atoms, bring oning redness and tissue harm. The hazards are particularly high among persons with preexistent bosom and lung complaints, including asthma and chronic clogging pneumonic disease, proposing that 1000000s of people with these conditions may be vulnerable to the jeopardies of inhaled nanomaterials. A assortment of nanomaterials has the capacity to do tissue and cellular harm by doing oxidative emphasis. Report shows that Bulkyballs caused oxidative harm to encephalon an d liver cells in a survey in largemouth bass. Other nanoparticles have besides been shown to do oxidative emphasis in tegument cells and liver. Oxidative emphasis may besides do harm to lung tissue. These sorts of perturbing behaviors have generated an pressing demand for more research about the safety of nanomaterials. The ethical usage of nanomaterials is a major country of concern for wellness attention suppliers. Obviously, guidelines along with the hazard possible with nanoamaterials should be created to continue human self-respect and unity. Much of the current focal point is to find what research should be done about the hazards of nanomaterials. Nanotechnologists have published five expansive challenges for the safe handling of nanotechnology. They are, develop instruments to measure exposure to engineered nanomaterials in air and H2O, develop and validate methods to measure the toxicity of engineered nanomaterials, develop theoretical accounts for foretelling the possible impact of engineered nanomaterials on the environment and human wellness, four ) develop robust systems for measuring the wellness and environmental impacts of engineered nanomaterials over a human life-time, and V ) develop strategic programmes that enable relevant risk-focused research.

Viruses Viruses share some characteristics with cells; however lack the qualities of living organisms. Viruses are simple structured organisms; they only have four structures that make them. They aren't considered to be living organisms due to several reasons such as reproduction and energy powered. They are often mistaken to be cells, however they are smaller and replicate inside of cells. Viruses are much smaller than bacteria and are capable to infect all types of living organisms. Viruses have four structures; the lipid envelope, capsid, genetic material, and the protein coat. The Lipid envelope is derived from the host cell membrane and play roles in viral infection and virus attachment to cells. The next component of the structure is the capsid; it is made from proteins, and is encoded by the viral genome which incases the nucleic acid of the virus. The third structure of a virus is the genetic material which is made of DNA or RNA, never both; it carries the genetic information which helps determine the composition of the organism. The last structure of a virus is the protein coat which helps attach the virus to a cell. Viruses aren't capable of reproducing outside of a cell therefore they don't meet the criteria of life and aren't to be considered living. Viruses are small infectious agents that are only able to replicate inside the living cells. They don't have their own biological "machinery" to replicate and doesn't multiply through cellular division. They also don't contain a metabolism therefore don't run on energy like living organisms. They just float around until they find a healthy cell to attach to and infect. They also can't regulate its temperature itself. Although viruses have a basic structure they are capable of infecting all types of living organisms and can cause serious damage. There is a blurred line between living and non-living although there are many good quality factors which make it non-living. Without a host viruses wouldn't be able to duplicate and infect organisms. Viruses are always mistaken for cells but never for bacteria, because they are much smaller and require a living host to survive unlike bacteria.

Learn How to Conjugate Monter (to Climb) in French A very useful verb, the FrenchÃ monterÃ means to climb or to go up. You can imagine how many times youll use it, which is why its important to study how to conjugate it so you can say I climbed or he is climbing in French. This lesson will show you how to do just that. Its also important that you do not confuseÃ monter withÃ montrerÃ (toÃ show). That oneÃ rÃ can make a big difference in the meaning of your sentence. The Basic Conjugations ofÃ Monter In French, the conjugations of verbs are more complicated than they are in English. While we can use -ingÃ for the present tense and -edÃ for most past tense uses, French requires a different form of the verb for every subject pronoun within each tense. While that does give you five more words to learn for each of the present, future, and imperfect past tenses, they are easier if youve studied similar words. Thats becauseÃ monterÃ isÃ aÃ regular -er verb, meaning it uses the same infinitive ending as the majority of French verbs. With each new one you learn, it becomes a little easier to memorize those youre not familiar with. To study the conjugations ofÃ monter, use the chart to match the subject pronoun with the tense of your sentence. This will indicate which ending is added to the verbs stem (or radical),Ã mont-. For example, I am climbing isÃ je monteÃ and we went up isÃ nous montions. While that seems simple enough, youll definitely want to practice these conjugations in context. Luckily, there are many commonÃ expressions withÃ monterÃ for you to use. Present Future Imperfect je monte monterai montais tu montes monteras montais il monte montera montait nous montons monterons montions vous montez monterez montiez ils montent monteront montaient The Present Participle of Monter TheÃ present participleÃ ofÃ monterÃ isÃ montant. Youll notice that this was formed by adding -antÃ to the verb stem, another rule that applies to almost every regular -erÃ verb. MonterÃ in the Compound Past Tense For the past tense, theÃ passÃ © composÃ ©Ã is an alternative to the imperfect. This is a compound conjugation, so you will need theÃ auxiliary verbÃ Ã ªtreÃ as well as theÃ past participleÃ montÃ ©. The phrase comes together quite easily. Begin by conjugatingÃ Ã ªtreÃ into the present tense appropriate to the subject, then allow the past participle to indicate that someone has already climbed. For example, I climbed isÃ je suis montÃ ©Ã and we climbed isÃ nous sommes montÃ ©. More Simple Conjugations of Monter There will be times when you may need to question whether the act of climbing took place or not. For those occasions, you can use the subjunctive. Similarly, if someone will climb onlyÃ ifÃ something else happens, the conditional can be used. Though you might not need either the passÃ © simpleÃ orÃ imperfect subjunctive, these are good to know. However, theyre used only on occasion, so they do not need to be a priority. Subjunctive Conditional Pass Simple Imperfect Subjunctive je monte monterais montai montasse tu montes monterais montas montasses il monte monterait monta montt nous montions monterions montmes montassions vous montiez monteriez monttes montassiez ils montent monteraient montrent montassent For direct commands and other short sentences, you can skip the subject pronoun and useÃ the imperativeÃ formÃ ofÃ monter. Simplify it toÃ monteÃ rather than the more formalÃ tu monte. Imperative (tu) monte (nous) montons (vous) montez

R. D. Introduction: The case is all about an increasing irrigation facilities after independence but there was certain problems with the removing location of BHAVNATH TEMPLE which is between the dam and people donÃ¢â¬â¢t want to change place of temple with that there are some other issue also there. After independence in 1947, the both central state government want overall economic development. In undivided Bombay province a proposal given to build dam on river. It calculated 4700 million cu. ft. Water to develop 92000 acre of land, In 3 district. To do that 8 villages are totally submerged and resettled at other place. This all require to providing new livelihood to people. The reservoir was to have catchments area of 230 sq. miles. The average rainfall was 34Ã¢â¬ . In this 1 plan the F. S. L. , was 592 H. F. L. was 596 and R. L. was 601. Directed irrigable area was 19300 acres and the indirect irrigation flow to some 73600acre. It yields 15. 83 lacks revenue per year. Agricultural production increase as 30400 tons. It was 147. 74 lacks. This project was fully feasible in the eyes of government. If plan 1 was accepted than temple was saved by using gates to save from flood. After making 1 proposal government made 2 proposal. In that, if all of three levels rose so that ultimate capacity raise to 1000 million cu. Ft. in that F. S. L. 595 H. F. L. 606. By doing this the agricultural production increasing and irrigation facilities provide to larger areas. But in 2 plan temple could not be saved but people remained adamant in there demand. IN 1960 state of Bombay bifurcated and now Gujarat PWD department began to think about reopened the plan again. They find this scheme was good for development. The problem is that what should do to become success of this plan. Objectives: Ã¢â¬ ¢ To build the dam, Ã¢â¬ ¢ To increase agricultural production, Ã¢â¬ ¢ Do ultimate overall development Problems: Ã¢â¬ ¢ Temple get submerged, Ã¢â¬ ¢ Religious sentiments, Ã¢â¬ ¢ Opposition by villagers Ã¢â¬ ¢ People get displaced. Constraints: Ã¢â¬ ¢ Location of dam Ã¢â¬ ¢ Religious sentiment canÃ¢â¬â¢t be changed. Criteria: Ã¢â¬ ¢ Cost should be minimized Ã¢â¬ ¢ Maximum returns Ã¢â¬ ¢ Minimum people affected Ã¢â¬ ¢ Minimum time in implementation Alternatives: Ã¢â¬ ¢ Plan 1 if no plan 2 Ã¢â¬ ¢ Resettlement of affected people Ã¢â¬ ¢ Wall around the temple Help from religious leader Ã¢â¬ ¢ Convincing people about benefit Ã¢â¬ ¢ Raising the height of temple Suggestion: From all above alternative we compare it with objectives, problem, and criteria we can suggest that to succeeding this scheme government should increasing level of temple by above than flood level with using good construction peeler so ultimately height of temple raised and they saved from flood. By doing so peoples are permit to build dam on river. Contingency plan: If it is not possible to build temple by construction of piller then take help from the religious leader.

How does music transform people and me - Essay Example For instance, when a person who feels sad and hears a certain song he particularly likes, he could be emotionally affected depending on the kind of music. Love songs oftentimes remind people of love relationships and can relate to the music. However, not all people are simply attracted to music because of the lyrics or the rhythm of the song. There are other certain aspects in music wherein individuals are particularly attracted to. Some people love to listen to loud music and prefer rock and roll over melodious songs. On the other hand, there are those who consider rock music as noise because they prefer softer melodies and choose country and classical music or inspirational like gospel songs. Through my observations, I think music speaks more than words to the hearts and souls of people. The effects of music can be manifested by individuals stomping their feet, nodding their heads, shaking their bodies or seem to dance even while sitting, when they listen to music. This is perhaps the reason why it is called the language of the soul. It moves the soul and makes itself apparent through actions. Some claim that they are able to concentrate more in what they are doing when they listen to their favorite music and I agree with them because I feel the same way. Personally, I love to listen to instrumental jazz. I am very entertained by Kenny G. and the Caribbean Jazz Project. When I pay attention to their music, it is as if I am transported to another world where I can be dreamy. It gives me a whole new perception which brings out the musician in me. I can imagine myself with an instrument making my own music and playing along with the sounds that I hear. So many times, such instances make me inspired to continue with my music and desire even more to become a good musician in the near future. Music strengthens me to always keep my dreams on focus and be unafraid of the challenges I face in life. Whatever choice of music a person has, it could perhaps be said that
