Nuclear Energy Essays (726 words) - Energy, Nuclear Physics

Nuclear Energy Abby Pros and Cons Nuclear energy represents only 15% of the electricity produced worldwide. Though in France, 80% of its electricity production is from nuclear energy and more than one-fourth of electricity in Europe comes from nuclear energy. Nuclear energy represents a very small percentage in many countries' total electricity production, but this percentage is likely to go up in the coming years. Nuclear power is generated using Uranium, a mineral of which one of the isotopes, U- 234 is unstable. The nucleus breaks down resulting in the emission of heat and radiation followed by a chain reaction. This is called nuclear fission and this process liberates a large amount of energy, but the process also releases radiation which is very dangerous. Nuclear energy has the ability to produce electricity without greenhouse gas emissions. It produces electricity without pollution. It is cleaner than many other forms of energy production. Essentially, nuclear power would be "carbon-zero" if the uranium were mined and transported in a more efficient way. Nuclear reaction releases a million times more energy, as compared to hydro or wind energy. Large quantity of energy is generated from a single nuclear power plant. Nuclear reactors make use of uranium as fuel and produces huge amounts of energy from small amounts of uranium. The Earth has the high reserves of uranium. Current estimates put the uranium supply as enough to last for 30 to 60 years. Moreover other fuel cycles like Thorium are available for power generation. Whereas, oil reserves and other fossil type fuels are likely to run out shortly. Nuclear power plants operate reliably and have a continuous output of power.The plants do not generally face operations and maintenance problems. This is a contrast to other alternative energies which depend on the activity of the weather. Although nuclear power reactors are expensive to build, they are relatively cheap to operate. Fuel is inexpensive and a plant can be operated by small number of people, approximately 10 people. The nuclear energy is by far the most concentrated form of energy, so it can be produced in large quantities over short periods of time. Produces small amounts of waste and waste is more compact. Nuclear energy produces electricity at a competitive price and is generally comparable in output to coal plants. A nuclear plant is not dependant on local sources like oil and coal and can be set up in any part of the globe. It also does not require a lot of space and so can be placed in already developed areas and the power does not have to be transferred over long distances. It has potential nuclear proliferation issues. Some reactors produce plutonium which can be used to make nuclear weapons. Nuclear weapons are a major threat to the world as they can cause a large-scale devastation. Nuclear Plants require a high level of technology and a major initial capital investment. Its abandonment cost is also very high. It takes a long time to build, about 15-20 years to develop a single plant. There are issues with management of radioactive waste. The spent fuel is highly radioactive and has to be carefully stored for many years after use. A solution to the waste management problem needs to be explored and developed. This has RD cost. An accident may cause a major disaster resulting in thousands of casualties and releasing high amounts of radiation into the environment, example: explosion of a reactor at Chernobyl Nuclear Power Plant in Ukraine and melting of the core of a reactor at Three-Mile Island in the United States. Nuclear energy is an alternative energy but not a renewable energy as Uranium is a non-renewable source and its supplies are limited. Nuclear plants may be vulnerable targets to anyone wanting to disrupt the power supply, and to have quite horrific results and to devastate an entire region. Today, nuclear energy remains controversial. There are proponents and opponents of nuclear energy, but nuclear energy along with other green energies has a major role to play in years to come. The actions to mitigate the risk associated with nuclear energy need to given due importance to harness its full potential.

World Cup Host Countries

World Cup Host Countries Held every four years, the Fà ©dà ©ration Internationale de Football Association (FIFA) World Cup is held in a different host country. The World Cup is the major international soccer (football) competition, consisting of the nationally recognized mens soccer team from each country. The World Cup has been held in a host country every four years since 1930, with the exception of 1942 and 1946 due to the Second World War. FIFAs executive committee selects the host country for each FIFA World Cup. The 2018 and 2022 World Cup host countries, Russia and Qatar respectively, were selected by the FIFA executive committee on December 2, 2010. On June 13, 2018, the 2026 host was selected through a new process, the open votes of all FIFA member countries. Note that the World Cup is held in even-numbered years that are the interval years of the Summer Olympic Games (although the World Cup now matches the four-year cycle of the Winter Olympic Games). Also, unlike the Olympic Games, the World Cup is hosted by a country and not a specific city, as is the Olympic Games. The following is a listing of the FIFA World Cup host countries from 1930 to 2026. World Cup Host Countries 1930 - Uruguay1934 - Italy1938 - France1942 - Canceled due to World War II1946 - Canceled due to World War II1950 - Brazil1954 - Switzerland1958 - Sweden1962 - Chile1966 - United Kingdom1970 - Mexico1974 - West Germany (now Germany)1978 - Argentina1982 - Spain1986 - Mexico1990 - Italy1994 - United States1998 - France2002 - South Korea and Japan2006 - Germany2010 - South Africa2014 - Brazil2018 - Russia2022 - Qatar2026 - North America (united bid by Canada, Mexico, and the United States)

Summarizing this Pdf to one page plz - Essay Example Depending on the ground plane size, a moderate to high efficiency is achieved. The antenna has a small fraction bandwidth of around 1%. As the ground plane size decreases ohmic loss increases and the antenna become more similar to an isotropic radiator. Symmetrically loaded miniaturized slot antenna applies boundary condition at both sides of the slot-line. Under this condition, re-configurability, selection of area with the peak current and variable miniaturization level is possible. Slot antenna uses inductive loadings to maintain the current level in the end of reduced size slot antenna. Since small antennas are narrowband, it is important to increase the bandwidth without compromising efficiency. Comparison between the miniaturized slot and miniaturized folded slot impedances shows an increase by a factor of four in the radiation conductance. Therefore, slotted structures demonstrate higher efficiency and lower losses and are thus preferred whenever a ground plane is

Lab report paraphrasing - Essay Example According to Experiment 1 observations, the T value of the signal when increased to 2 seconds from 0.5 seconds in 0.5 increments, the Fourier Transform accuracy also rises. Consequently, it is also evident that when the value of T is 0.5 seconds, the graph appears exceptionally different from the other 3 graphs since the period is not a big number to show the 2 tasks. These roles are actually the ones indicated on with line with the other one being made from the size of the troughs and peaks. This can clearly be seen when T=2 seconds in the graph in experiment 1. A correct value could not be displayed by the power spectrum because T value was too tiny. As illustrated, whenever the value of T rises, the power spectrum begins to exhibit the 2 co-sinusoids. When the experiment is over, it becomes clear that the magnitude of code required to solve the FFT is much shorter and simpler than the substitute DFT code. The other point to put into consideration would be the results obtained in section 3 of experiment 2.Thus, these results showed the time consumed to determine the DFT as well as the FFT, something that demonstrates that the FFT is quicker and realistic for determining the Fourier Transform. Consequently, FFT can be utilised in different methods through the entire electrical engineering comprising of researching on audio waves as well as the technique involving the audio signals, especially in recognition of pattern in instances where an engineer is searching for definite similarities or points, in addition to medical imagery like MRI scans etc. The above are just a few of numerous uses that electrical engineers are provided for by FFT at

Childcare Act 2006 in a Childcare Setting

Every child matters foundation set standards for the well-being of young children ensuring safety/health/economic/well-being/Achievements and Positive self steam. Legal Requirements for childcare providers are published via Ofsted under Statutory Framework for the Early years foundation stage EYFS. The Statutory framework stage within the EYFS has a number of requirements sectored. Involving; School leaders/staff Childcare providers/childminders Nurseries Pre-schools/playgroups childminding settings Maintained/non-maintained and private schools Developments Learning/development Welfare Additional legal information Regulation information assessment scales legal information in relation for adult to children ratio. The Framework provides direction/order to ensure all early year providers are meeting expectations for growth intellectual/physical developments required for when they enrol for mainstream school. Including the health/safety of the children. https://www.gov.uk/government/publications/early-years-foundation-stage-framework Learning/development requirements The authorised requirements MUST be met by the provider. The type of childcare setting/children all need to be put into considered while requirements are being pursued. Resources to ensure this are accessed via internet access: (http:/www.gov.uk/government/uploads/system/uploads/attachment_data/file) Development requirements childcare Act 2006 Early learning expectations. The child should hit the target of development/achieve; Knowledge/skills/comprehension of the standards that a child should reach by the age of five. Education Programmes skills/processes lectured by the provider. Assessment arrangements structured for the continuation of achievements. Learning standards/expectation Supporting Personal, Social and Emotional Development is a standard set to support development of skills; Self Confidence/learning/communication/sociability skills for future friendships and confidence. Comprehension of their environment is a development educed to expand fact/theory of their surroundings, also influencing the learning of technology/individuals and other areas. Physical Development; This is an imperative stage of development as children should always be subjected to activities influencing/permitting physical activity. Improving their co-ordination/physical strength. Also providing an education on the benefits to themselves via participation leading to a healthy lifestyle and a variety of good food options/benefits. Mathematics; This is a standard targeted to introduce numbers to the child for prior knowledge for enrolment of when mainstream school commences. Involving; Configuring shapes/measurements.

Expressive Arts and design: Creative play is a form of educational play for children to produce Self confidence, Understanding of the role/express feeling. This can involve role play/Dance/Art work/performance or music. Assessments This is a requirement made to observe any target standards made by Statutory Framework for early years have been met or made progress. During the assessment observations are documented evidence which is recorded via the childcare provider. There also needs to parental contribution made for communication between provider/parent. The Legal requirements are established by the Statutory Framework for early years foundation stage. To ensure the well-being of safe guarding children. The requirements focus on the promotion of the childs welfare within the setting; The childcare providers are all CRB checked and suitable. Environment, Equipment and Premises are to standard. Documentation is clearly constructed. Organised forms of education for learning, emotional, social, physical and interlectual development are in operation. Legal requirements for safe guarding children involves met/passed standards; Information of complaints documented Premises and security Outings Equality of opportunities Medication Illness/injury Food/Drink Smoking Behaviour management Safe recruitment (CRB checked) Correct Number of staff for children Risk assessments Premises. Respecting/valuing individuality The understanding of each individuals personality can be taught from a early stage. It is important from a young age for each child to realise and understand that each person is different and may have a respectful difference of opinion. The influence of their elders impact a child perspective greatly as of which it is of vast importance to set good values for the child to develop good characteristics becoming a decent member of society. Children are influenced how to behave via their elders, as a child learns via observational skills. Setting a good example of how to behave is important as it can greatly affect the upbringing of the childs behaviour/personality. The childcare setting surroundings should advertise images of positive perception of the world including all cultures as a human race and mother nature. To promote individuality there should also be access to role play, toys, and electronics. Their maybe a Varity of practiced cultures within the childcare setting. Therefore its a good idea to introduce a monthly cultural lesson on any cultures present within the group so children can understand the differences between cultures, using the foods, animals, preparations, weather, clothing is used and why!. The cultural lessons can educate the child to enhance their intellectual/emotional and social development as it influences children to talk about the way they live inviting a group discussion. Achievement days/awards are extremely effective upon the childs self confidence as the award presents the childs achievement/s. An award/award chart leading to an award day may influence the child to work towards the award for self satisfaction of learning or behaviour. The awards day can also be via the involvement of outside activity hobbies, Swimming/dance/football clubs, which can be discussed within the setting, promoting information on possible outside activities permitting children to express their excitement of their achievements. Group work is essential to child social development as it concentrates on communication/structuring ideas/problem solving and compromising with others. Role play is a great way to promote group communication as there has to be discussion/agreement in who plays which role, confidence with discussions, understanding the roll and discussing it and respecting all thoughts/theories. Personal values can be influenced via good routines, interaction within a good/comfortable setting, such as story time, understanding when to listen and the appropriate time to proclaim their thoughts via showing understanding of the concept. Positive/Negative Behaviour From day one a child is effected by his/her environment. As the child develops there are boundaries needed to be put into place to ensure positive behaviour development, as the child understands right from wrong therefore grasps an understanding of the correct responses/actions. without the examples the child can develop negative behaviour and become confused. Boundaries permit the childs understanding of how to behave therefore understand that if rules are not practiced there will be consequences. The child need to understand whats right or wrong as negative action can put others at risk such as pushing another child or smacking/biting. without consequences a child will not comprehend the action is wrong or will take liberties. Rewarding a positive action/praise is a well achieved award or emotion for reaching/gaining credibility at any stage of development/age i.e. If a child is successful with potty training/behaviour or socialising. Awards/praise influence children to achieve/progress goals. The outcome to the award method is so the child eventually doesnt rely on a form of award and continues to proceed with positive actions, this is where a disciplinary act should be put into motion if any negative behaviour become apparent, if the child out steps their boundaries then a cause of action should be solicited; The naughty step (minutes time out for the duration of the childs age) or no favourite food/book to read. If no action is taken the child could proceed with negative behaviour/anger problems. A group discussion of behaviour expectations should be an active source of communication between peers/providers to ensure a friendly/happy/safe environment. Negative behaviour: create a adverse impact on the childcare environment for everyone present. The victim of the situation can become very distressed/upset effecting child/provider. The incident should be addressed (by the provider) as soon as possible as the child/children of cause will be able to comprehend where they have stepped out of line. The provider will have to explain where the child went wrong, as just saying NO will not deliver the insight of what they did wrong. The provider needs to introduce boundaries within the childcare setting to enforces the correct expectation of behaviour. Awarding the child for good behaviour needs to be introduced and is just as important as discipline. Even though negative behaviour is more apparent to good behaviour, applauded good behaviour can encourage children to want recognition/positive response from his/her providers/parents and peers, even though discipline needs to be an active consequence, sometimes on minor instances if the child gains no response then the child will learn he/she wont gain the required attention. Otherwise if little/no good behaviour is acknowledged the child will always feel like they are naughty and lack enthusiasm for improvement. If good behaviour is applauded then this will encourage future good behaviour eventually become a positive impact improving the childs actions. It is imperative to be consistent with the message being preached to the child involving positive/negative behaviour, even a simple mistake can influence the wrong message so clarity/consistency is highly important. A positive attitude from the provider can determine the atmospheres positive or negative vibe, this can create a happy/safe positive environment for the children/providers or a negative/unhappy one. Its of great importance the child feels safe/inspired/happy within their childcare setting. Conflict management between children/adults Unfortunately conflict occurs within every childcare setting, It is the way it is addressed which leads to a positive/negative standard of care. A conflict can be present between children or a child struggling to except the providers authority. John Broadus Watson An American psychologist whom established the psychological school of behaviourism. Watson was the author of Psychological Care of Infant and Child in 1928. Watson believed children should be treated as a young adult. He proclaimed that the inevitable dangers of a mother providing too much love and affection can provide a negative impact upon the childs future, He proclaimed that the love affection response was conditioned love. Impacting the future generations by mentioning Invalidism proclaiming that society doesnt show high affection to the developing older children/young adulthood within the real world, therefore parents/careers should not deliver high expectations of reality. Watsons views of Nature and nurture was that nurture was the corrected theory. Hes theories were that nobody is born with natural instinct and supporting this theory he believed that all knowledge is gained via interaction with his/her environment and parents should take sole priority for the responsibility they relinquish upon their children. Conditioning; http://www.simplypsychology.org/classical-conditioning.html) There are debates on how conflict impacts a childs upbringing. Positive views of conflict include it to be a natural emotion of life and should be expressed, supporting Watsons theory in nature and expectations of life. Negative views introduce beliefs that conflict can inflict anger therefore effecting ones social abilities via lack of suitable role model. Critics of Watsons views; Needs which are unmet; due to lack of physical/mental emotion leading to Cravings for attention. Selfishness; Leading from lack of emotion, the child can become an adult with difficulties to understand others needs of love and attention/affection. social skills; As the child finds it difficult to understand other childrens different thoughts and views. http://en.wikipedia.org/wiki/Childcare_Act_2006 https://www.gov.uk/government/publications/early-years-foundation-stage-framework (http:/www.gov.uk/government/uploads/system/uploads/attachment_data/file) Conditioning; http://www.simplypsychology.org/classical-conditioning.html)

Alzheimers Disease Essay -- essays research papers fc

An Exploration of one of the Most Mysterious Diseases   Ã‚  Ã‚  Ã‚  Ã‚  Alzheimer’s disease, named after Dr. Alois Alzheimer, is a disease that is on the rise in America and the rest of the world. People should learn as much as they want about this disease, because as you age, your chances of becoming an Alzheimer’s Disease, or AD, patient increases. It is estimated that approximately 3 percent of Americans between the ages of 65 and 74 have the illness, and more than half of all people over age 85 have the ailment.   Ã‚  Ã‚  Ã‚  Ã‚  AD is a form of dementia, a disease, that according to the Alzheimer's Disease Education & Referral Center is defined as: â€Å"†¦a group of symptoms that are caused by changes in brain function. Dementia symptoms may include asking the same questions repeatedly; becoming lost in familiar places; being unable to follow directions; getting disoriented about time, people, and places; and neglecting personal safety, hygiene, and nutrition. People with dementia lose their abilities at different rates.†   Ã‚  Ã‚  Ã‚  Ã‚  It is not uncommon for AD patients to become lost and wander away from their homes, thus leading to a very disturbing and upsetting experience for family members.   Ã‚  Ã‚  Ã‚  Ã‚  Alzheimer’s can be diagnosed before age 65, although rare, and is caused by a mutation in 3 known genes. About 5 percent of those who are under 65 and possess the ailment have AD in their family history. Given that the symptoms of AD are caused by plaque in the brain, causing loss of nerve cells that help the body communicate with the brain, mutations to these genes; amyloid precursor protein, presenilin 1, and presenilin 2 cause a excessive production of certain proteins (primarily a B-42 form of amyloid protein), and therefore spark an excessive growth of plaque cells which are toxic to the neurons of the brain. For those cases of Alzheimer’s that occur after age 65, a genetic mutation has yet to be proven, although some may be linked, to the fact that a difference may cause an increased chance of developing the ailment. Whatever the case may be for patients over 65 years old, the disease and its symptoms are caused by neurofibrillary tangles of al myloid plaques. It is impossible for someone to test positive for Alzheimer’s Disease, because the only way to determine an affirmative case i... ...t one has it. Many scientists hypothesize that there is an inflammatory response in the brain when there is an extensive B-42 amassing. To slow or stop this, scientists theorize that the use of anti-inflammatory drugs, such as aspirin, could delay the swelling in the brain. Also, as scientists have known that taking a multi-vitamin tablet each day is good for you, there has been recent research demonstrating that the use of antioxidants may protect neurons, not just the immune system and keeping the body healthy by providing vitamins and minerals. These special supplements protect the neurons from the effects of the accruing B-Amyloid that would likely cause the plaque that causes AD.
