Uses Of Nuclear Energy In Agriculture

Uses Of Nuclear Energy In Agriculture Nuclear technique is being an important application in many sectors such as food agriculture, industry, medical, environmental protection and power production. It is known that there are both advantages and disadvantages of using nuclear energy. However, nuclear energy is being widely used in agriculture which includes food production, animal production, crop production, fertilizer, soil fertility and more. According to Farm Press, nuclear power is considered cheap to be used in agriculture development. It has been reported that the increasing price of gasoline, electricity, diesel fuel and natural gas is one of the major problems to farmers. Nuclear energy is found to be the cheapest power source for agriculture. For example, nuclear energy can be used in production of nitrogen fertilizer instead of natural gas which has increasing price nowadays. Co-ordinated Research Project (CRP) was carried out on the use of nuclear techniques for optimizing nitrogen fertilizer application under irrigated wheat. It has been found that this technique increases the efficiency of nitrogen fertilizer while reduces environmental pollution. Other than that, Khanal and Munankarmy (2009) stated that there is possibility to improve health, feeding and fertility of livestock. They further explained that nucleic acid hybridization (nuclear related technique) is a promising technique for disease diagnosis. The conventional approaches of disease diagnosis involving direct detection and isolation consume more time compared to nucleic acid hybridization. Thus, it is said to be very effective in terms of time and sensitivity. Besides that, this technique is also unique because it focuses on the genome of organism instead of its products. According to the study conducted by Khanal and Munankarmy (2009), ionizing irradiation is another nuclear technique which plays a vital role in animal health. Virulence of some parasites can be eliminated using this technique which also helps to produce safer and cost effective vaccines. These methods have increased the rates of growth and milk and meat yield. There are some non-isotopic nuclear techniques that are being implicated in agriculture, especially in livestock production (Makkar, 2008). Gamma irradiation is one of the non-isotopic nuclear techniques. This gamma irradiation is an effective technique which enhances nutrient availability in plants that are fed to livestock. According to Makkar, content of plant secondary metabolites in some of the unconventional feed resources, could give adverse effects to the feed of livestock. He further explained that bioavailability of nutrients decreases at high levels of plant secondary metabolites. Thus, it is found that gamma irradiation is an effective technique to inactivate the adverse activities. Committee On Agriculture has discussed on à ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒâ€¦Ã¢â‚¬Å"nuclear techniques in food and agricultureà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ã‚ . This committee stated that nuclear related techniques help to improve the food production system in terms of stability, resilience and productivity. Biodiversity of crop plants can be increased by radiation induced mutations which change the genetic make-up. For instance, mutation breeding has given more than 3000 crop varieties of some 170 different plant species in more than 100 countries. This includes rice that grows successfully in saline soil and barley that grows at 5000 meters. Nuclear technique is playing a vital role in soil and water management system. It is important to improve soil moisture conservation measures and reduce wastage of irrigation water which leads to the improvement of water management in agriculture. One of the nuclear techniques that help in soil and water management is Soil Moisture Neutron Probe (SMNP). SMNP is a portable device that is used to measure soil water content at different depths through access tubes installed in the soil profile. Data obtained from SMNP are used to calculate the soil water balance and estimate the total amount of soil water removed from soil evaporation and plant transpiration (Joint FAO/IAEA, 2004). Furthermore, nuclear techniques are also used to identify the source of soil pollutant. This helps farmers or environmental planners to know the specific sources of pollutant and design most appropriate management strategy, so that the impact of pollutants can be reduced. For example, fertilizers and pesticides that are used to improve the agricultural activities can become pollutants if they reach the rivers, streams and lakes. To overcome this problem, fallout radionuclides are attached to soil particles which can track the movement of soil particles from where they originate (Nuclear Technology Review, 2007). On the other hand, nuclear energy also has disadvantages. One of the major concerns about nuclear energy is there is a chance for severe accident to occur in the reactor. This accident is very dangerous because it releases radioactive materials into the environment. In 1986, there was a Chernobyl accident occurred in Ukraine. It was caused by the flawed Soviet reactor designed coupled with mistakes made by plant operators. As a result, 30 operators and fireman died within three months (Scientific and Technical Committee Euratom, 2001). Scientific and Technical Committee Euratom has explained on another negative effect of nuclear energy. According to this committee, nuclear energy produces radioactive waste which is very dangerous. There are two types of wastes: short-lived and long-lived wastes. Many countries have safely disposed the short-lived wastes. Whereas, the long-lived wastes which are generated in a very small amount are conditioned and stored carefully without releasing it to the environment. However, the final disposal of long-lived wastes is still an unsolved problem. As a conclusion, even though nuclear power has disadvantages which are really harmful to the environment and human beings, it should be still encouraged to use it in agriculture. This is because nuclear energy is really needed to improve our Malaysian agricultural sector which is the main focus of our country as our ex-prime minister decided. It is suggested that Malaysian government should encourage creating more researchers on nuclear energy. Other than that, our government can implement joint projects with developed countries, so that more application of nuclear energy can be used in Malaysian agriculture. At the same time, it is very important to be aware of the dangerous of using nuclear energy and always be safe and secured.

Televisions Manipulation of the Facts Essay -- Argumentative Persuasi

Television's Manipulation of the Facts    One of the main activities that American's participate in during their free time is watching the television. Since its invention over sixty years ago, the television has been a source of enjoyment and information for the American citizen (Pember, 1981). Though what one sees on the television is not what one should always believe. Many people look at television with the "camera never lies" attitude, and are easily manipulated by this medium. People are manipulated by television because most television programming is controlled by a small number of companies, this is a main source of information, and people all too often trust what they witness in the media. Because television is controlled by an oligolistic market, the few companies that do control television programming are able to benefit from a great deal of selectivity, and would not put something on a news cast that would harm their business. The media is also able to manipulate people because television is one of the main source s of information in this country; from local news casts, to news related magazines like 20/20 and Dateline. These programs show a very limited view of the facts due to time restraints and company wide bias (Kaufman, 1998). And many people do not question what they witness on news shows, which can be very detrimental the their own knowledge of the facts. These three causes promote a society where the media many times has the upper hand in directing people's decisions, and therefore manipulating society as a whole. In the modern era, with cable and satellite television there is wide array of programming to choose from. A television connected to the latest technology can receive over 200 channels.

School activities which facilitate the learning of the students

School activities which facilitate the learning of the students can either be inside or outside of the classroom. Nonetheless, all these activities implicate behavioral expectations which the students must meet. In-class activities include the use of learning centers and computer stations. This activity facilitates learning through the use of different sources which provide the students a better understanding of the lesson. In addition, learning centers and computer stations give the students some hands-on training, which is very effective because it adds up to the learning experience of the students.Finally, these faculties of learning allow the students to enrich their knowledge and imagination, not only limiting the things to be learned to what the teacher has said. For this kind of activity, the students are expected to use the particular source efficiently so that it may help facilitate and enhance learning. This means that all available sources, such as computers, must be used with relevance to the academics. Moreover, the students are expected to practice courtesy. They should be responsible and not be abusive to the things which the school offers.One should also be courteous to his or her fellow classmates, and most especially to the teacher and other personnel present in the particular learning center. Another in-class activity is the teacher-led activities. This kind of activity makes the teacher the sole facilitator of learning. The teacher is the one who gives the basic rules or general instructions of the activity, and lays-out its objectives. The students, on the other hand, are the participants in the learning process and they are the ones who generate the ideas, key points and values of the activity.Basically, at the end of the activity, the teacher summarizes everything the students have said into few general ideas, and sometimes asks the class to repeat them. For a better focus on the students’ attention and participation, the teacher m ay also ask a volunteer from the class to summarize the general ideas of the activity instead of simply saying the main ideas. Finally, the teacher evaluates if all the objectives have been met, then proceeds to the lesson or next activity. For this kind of activity the students are expected to listen attentively to the teacher.They should be attentive in order for them to understand the instructions, objectives and ideas of the activity. Secondly, the students should practice a sense of responsibility. They should be able to know their priorities, what they need and need not to do whenever there is a teacher-led activity which requires their full attention and active participation. Learning does not only take place inside the classroom. Therefore, schools also conduct out-of-class activities in order to let the students experience and explore. Most common type of out-of-class activities include playground time or recess.This is a few-minute break after two to four subjects to give some time for students. This particular activity is a good embodiment of learning outside the classroom. With regard to behavioral expectations, all students are expected to practice camaraderie. This is the time when they are able to socialize with one another. Therefore, they are expected to behave properly, talk to fellow classmates and create friendship. In addition, they are also expected to learn the value of sharing and unselfishness. Friendship grows in the light of sharing. Students must know how to think of other people.Another interesting out-of-class activity is the field trip. This well-planned activity is an educational trip to different places of great significance, usually held once a year. The trip intends to familiarize the students with the historical and cultural significance and influences of the places to be visited. In this kind of activity, the students are also expected to practice camaraderie. This time, the context of camaraderie is deeper because the stud ents are going out of the school into different places and are spending more time with each other.Moreover, the students must be obedient in the sense that they need to follow all instructions given by the teacher in order to avoid problems. The basic method of determining whether the students did or did not understand the proper behavior expected from them is by way of asking. After the teacher has given the activity and the proper behavior expected from them, he or she must first ask the students what they did not understand to what he or she has said. If there is a question raised by one of the students, he or she must restate what is expected of the students and expound it.He or she must make sure that every behavioral expectation she mentioned was clear to the mind of the students before proceeding to the activity. Another effective way of evaluating the students’ understanding of behavioral expectations is by definition. This is to be done after the activity has been fi nished. The teacher will ask the students to define the behavioral expectations he or she has given the class before the start of the activity. By this method, the teacher will fully know how well the students understood the values expected from them.
