Universe Existence Essays - Black Holes, , Term Papers

Universe Existence The oldest profession in the world is not what would be commonly accepted in society. Before a woman had a chance to sell her body, people looked up at the stars and wondered what they were. They made figures out of the shapes they made. As we advanced through scientific research many other doors opened that allowed us to see what it was the earth is existing in. Our constant need to explain what is happening comes from our want to control. Knowledge is power, and nothing is more unexplained that the universe. Time is interlocked and must be understood if we want to accomplish a deep knowledge of the cosmos. Commonly it was thought that there was no such knowledge. The author Stephen Hawking had shown many otherwise. His books give a deep history and knowledge of how the universe exists. He also explains many others aspects of the cosmos and puts his works in an understandable writing style. He puts the largest accent on his studies of black holes. These are fascinating happening and the way to understanding the universe and several others can be found through the study of black holes. There are several features of black holes that makes them incredibly fascinating. The first one would be the common misconception of how noting can escape a black hole. This is true in most points. If nothing can escape them, how does one detect a black hole? Stephen Hawking discovered a fascinating aspect using anti-particle properties. He found that when matter is pulled into a black hole by gravity matter is constantly being pulled apart. This causes the anti-parties of matter to be throw away at incredible rates. This happens at consistent times. The large amount of gamma radiation let off by this is how Mr. Hawking now finds black holes. Another interesting concept of black holes is they are can be formed other ways than by the end of a star's life. Stephen Hawking and his associates found that any nuclear explosion can cause the birth of a black hole. Hawking stated that is all the "heavy water", a component used in nuclear weapons, was used to create a nuclear explosion a black hole the size of earth would be created. He also stated no one would be around to witness the creation. It would have been caused by the implosion of earth at a massive rate and the amount of energy produced by the nuclear explosion. This had me wondering. Stephen Hawking also stated that is a black how small enough not to disturb the orbit of earth existed close enough to earth that it's power could be harnessed to produce huge amounts of energy. This made me wonder if the same concept could be used, except with all the wastes materials on earth. I do not know the exact physics of it all, but from Mr. Hawking explanations it seemed like it might work. Black holes were also explained by Stephen Hawking as how they transcended time. Apparently the massive gravitational pull creates a rip in the space-time continuum. It is unknown what happens to matter when it is pulled into a black time wise. All matter will be ejected into space eventually as the black hole loses itself. The smaller a black hole, the more matter is ejected. It may be an odd happening, but because of the larger black holes are harder to detect than smaller black holes. Mr. Hawking stated of how if an astronaught gets pulled into a black hole the tidal forces would stretch him into a long piece of spaghetti like person. However, his life would not end in the black hole. Given enough time he would be eventually ejected into space as particles. All matter in a black hole will eventually be lost into space. The smaller a black hole is, the more matter is lost by the black hole. Stephen Hawking explained what is thought to have happened to a black hole when all its matter is lost. The hole in the space-time continuum would collapse and an explosion as massive as on of a supernova would happen. It would leave the tear in time. I wondered when the explosion would happen? Would it happen now, or ten to trillions of years from when it actually collapses. The tear in time where would it exist? Until an actual black hole is found close enough to us I suppose these questions will remain uninsured. Stephen Hawking explains many other aspects of

A New Life Essay Essay Example

A New Life Essay Essay Example A New Life Essay Essay A New Life Essay Essay A New Life Hopefully everyone can relate to a significant event in their life. Something that might have created a big deal of emotions, perhaps sad or happy. For example; forever bonding with a partner by legally marrying, or maybe the joy of knowing that after all those hard sleepless nights you’re being rewarded a lot more of those not by one, but two little twins, or maybe, â€Å"just maybe† you might have been one of those lucky lottery players that has the chance to spend the rest of your life spending. But not me. One significant moment that changed the course of my life was getting hired by Homestead Hospital. For an event to be significant it must have some kind of value to you. At that point of my life that moment had a tremendous value because it not only rescue me from this choppy glass of water in where I was drowning and even though there was not enough water to relieve my thirst I was drowning in it, but it also gave me an opportunity to pursue my goals. Something that I was starting to feel the sense of never being able to do. The reason was; I had just found out that I was going to be a Daddy at the age of 19 and if that was not enough I was handed the ultimate ultimatum, a letter of â€Å"termination†. Termination! From where? Well if I know your question then you must know the answer. From my job. A job that was second to school but after the wonderful news of being a daddy it was telling school to move back one spot. It all started after a few days with no sleep, after a few days of driving, calling and more importantly a lot of rejections. In no point in life I had felt so miserably impotent and what at first started as days turned to weeks in a hurry. I had started to lose it when I received a call from a young lady from Homestead Hospital. She said she worked with Human Resources and politely asked me if I was still interested in the position I had applied for. For a second I talked to myself, and for a second I felt offended. But

Termination Essay Example | Topics and Well Written Essays - 750 words

Termination - Essay Example In such instances, it generally becomes necessary for the organization to consider terminating the employee. Termination should be considered as the most severe form of punishment that an organization can possibly impose on an employee and as such, it should be the most carefully considered form of disciplinary action. The experience of going through a job termination is considered to be traumatic for all of an organization’s employees. Of note is that the termination of employees at different levels or positions within the same organization varies considerably; Unlike the employees working in the lower level positions of the organizations, an organization’s executives and CEOs often do not have to worry about the probability of their positions being eventually eliminated. The main worry that individuals at this level often have is that of ensuring that they constantly try and please the organization’s board of directors because it is these boards that are tasked with the responsibility of firing and hiring of these executives. Most of the time, the board of directors only undertakes the rather drastic action of firing an executive or CEO due to a loss of confidence in the executive. This loss of confidence might be brought about by a number of factors that include a general decline in the level of productivity, the emergence of philosophical differences between the executive in question and the board of directors, economic reasons, or if there is a need to reorganize the organization. Of note however is that there are currently no formal termination appeal procedures for employees at this level (Mondy, 2013, p. 367). This group of employees is widely considered to be the most neglected and vulnerable in respect to employment termination. While an organization’s executives generally tend to have a considerable degree of clout that might aid in helping them to successfully

I need write a letter to my parents in brazil, and explain to them Essay

I need write a letter to my parents in brazil, and explain to them what homeland security is and what my future will be in my ne - Essay Example The United States Department of Homeland Security came into existence in 2002 as a consequence of the Homeland Security Act. The Federal Homeland Security is responsible for coordinating the activities of roughly 187 Federal agencies dealing with varied aspects of the US security. The job of the Homeland Security is to prevent terrorist attacks on the US soil and to minimize the damage inflicted by such attacks. A career in such an agency requires a lot of sincerity, dedication, skills and hard work. It is different from the other jobs in the sense that it demands perpetual alertness and a 24 hour commitment from its adherents. However, those who are willing to give their best and utmost, it do promises ample satisfaction and rewards. Besides, the very concept and idea of working to protect the fellow citizens is in itself a source of great pride and motivation. I do believe that I will do really great in this career. Yours lovingly, Name of the Student.

Liability of Law Enforcement Officers WK7 Term Paper

Liability of Law Enforcement Officers WK7 - Term Paper Example Thus, the robber turns on his car trying to escape a police officer and the penalty which he had to follow. Police officer could not stop him, and he took a gun and fired. In that particular case, which is called ROCHELLE BROSSEAU v. KENNETH J. HAUGEN, robber sued the performer of Law. Verdict was in favor of the police officer. Also, the mother of three children reported to police that her estranged husband took children, and that he has a restraining order because of the application of force. Mother called a police for several times and they were saying to calm down and wait for him to come back. After several hours mother went to the police station, claiming that her kids are still missing.Few momments later her husband, the reported one, came into a station and opened a fire with his machine gun.Officers shot him down.In the back of his truck they found a dead children bodies.The mother filed a lawsuit against the city, its police and three officers that she was talking to on the phone; however the judgment was in their favor, and all of the lawsuits were objected. Police officers have a tough job, even without thinking about potential lawsuits, which does not mean that the law can be put into their own hands and to interpret it how they want. Police is indicated that the law in their hands and no one recalls that it isn`t the Law who is working for them, but they are working for the Law. Basic laws, such as in the first case, the Fourth Amendment violation, they neither respect nor were punished for it. Every man has right to say and do what he wants, if that is not against the Law. Every man has a right to be punished for his wrong dids and to take charge on anyone who is violating his right to live or express himself, in any way. Everyone have a right to have a fair trial, even if the prosecutor is tramp and the

Natural Product and Metabolomics

Natural Product and Metabolomics Mass Spectrometry is often become very useful comes into the final confirmation stage of a chemical structure. This is because by noting the fragmentation pattern and the total molecular mass of compound, researchers will be able to confirm the compound’s chemical formula, followed by confirming the chemical structure proposed based on previous instrumental analyses. Nowadays, Gas Chromatography and Liquid Chromatography are coupled with mass spectrometry in order for researchers to obtain the molecular mass right after the compounds are separated chromatographically. However, GC-MS are more often being used to study natural product compared to LC-MS because LC-MS doesn’t have its database constructed like GC-MS due to the extensive range of secondary metabolites and it is hardly reproducible. (Lee Yoon et al., 2013) Researchers can confirm the compound by matching the molecular mass obtained from GC-MS with the established database, while LC-MS users will have to refe r to the data provided by previous researchers on that particular field of study. There are a lot of journals regarding the studies of primary and secondary metabolites being published and a lot of researches will insert their sample for GC-MS experiment and then compared their compound’s fragmentation pattern and also molecular weight to the National Institute of Standards and Technology libraries, which will tells researchers the structure of their compounds, even if there are no exact matching, researches will at least have a rough idea on their structure. In the early 1990s, Solid-phase microextraction (SPME) was introduced to extract compounds from samples without the use of solvent; this method is later applied on samples before undergoing GC-MS process. This technique enables researchers to extract compounds from sample in a much simpler and cheaper way since it doesn’t include the use of solvent. SPME works by adsorbing compounds into its fibre coated absorbing phase from the sample, and then inserted into GC for desorption of compound into it and then separated. (Dagostino Sanz et al., 2014) This technique is so convenient that researchers can even carry it along when going into a jungle to adsorb compounds from plant of interest and bringing it back to the lab to undergo GC-MS experiment, much more convenient than plucking a big bunch of plants sample to the lab for solvent soaking. Samples can be injected into GC-MS through either split of splitless injection; split injection system will direct most of the samples out to the atmosphere and only allow approximately 1% of it to enter the column while splitless injection system allows most of the samples to enter the column. Split/splitless system are designed to give reproducible chromatographic retention times and also to keep the chromatographic requirements of column in place, to use split of splitless, it is depending on the sensitivity required. Though splitless system allows more sample to be injected in however, metabolomics researches are better be carried out with split system because metabolites are present in wide range concentrations and it allows researchers to analyze volatile compounds eluting near the solvent peak. (Cyril Jousse, 2009) Besides plant’s metabolites, GC-MS is also very useful for bio-metabolics, some of the bio-metabolics researches are for example Chrysoula Christou et al. did a research on analysis of organic acids in human urine in clinical settings in order to develop a method for organic acid profiling in human urine, this can be useful to detect metabolics or other health disorders. Their sample was being separated by gas column and undergo quadrupole mass spectrometer in the electron ionization (EI) mode and as a result chromatogram and mass spectra shown 11 organic acids separated and identified by conducting similarity search on NIST library (3). A research was carried out by Ioannis Papoutsis and the team of research. where GC-MS method was used to determine amisulpride in blood. Amisulpride is an antipsychotic drugs which is prescribed to psychiatric patients, overdosing can cause arrhythmia, bradycardia and hypotension. (4) SPME was first used by them to extract compounds from the b lood samples and then separated by using gas chromatography and finally detected by mass spectrometer, results show that GC-MS can be used to monitor amisulpride in the blood and this can be used in pharmacokinetic studies and also forensic investigation. Archeology GC-MS is also used in assisting archaeology studies; it is especially useful when comes to determining the chemical constituents of the sample. In one of the recent archaeology research, M. Mà ©nager, C. Azà ©mard and C. Vieillescazes studied the mummification balms from the mummy skulls with FTIR and GC-MS. Twelve mummified heads were collected, the balms on the heads were extracted with organic solvent and water before introduced to GC-MS. Molecular components were eluted by using helium, and injected with split system. Samples were eluted by using helium as carrier gas with the flow of 1mL.min-1 and oven temperature was set to: 50  °C for 2 min, 50–250  °C at 8  °C ·min−1, 250–350  °C at 3  °C ·min−1, and 350  °C during 20 min. 1 ÃŽ ¼L of each sample was injected with a splitting system and the injection temperature was set at 250  °C. Mass spectra were generated by electron ionization mode with electron ionization energy of 70 eV, an ionization time of 25,000 ÃŽ ¼s and a mass range of 40–650 m/z. (5) As a result, those mummification balms were found to contain mixtures such as oils, fats, beeswax, resins, proteins, polysaccharides and minerals, these compounds are confirmed again by matching mass spectra with NIST library. With the use of only FTIR without confirmation by GC-MS, researchers will only be able to know the functional group in it without confirming the compounds. Cosmetic In cosmetic industries, chemical compounds in every cosmetic must be carefully studied as it’s applied onto human’s skin and body, therefore any mistake made will cause allergy or irritation to end users. Synthetic husk has been widely applied in cosmetic industry due ti its long-lasting odor, however, it was found that two groups of synthetic musk can cause many health disorders. Many countries have also set up regulations on the amount of synthetic musk in order to protect end users, this has become another parameter in quality control of cosmetic products. In Beijing, China, Haifeng Dong and his team of researchers conducted a research on 7 synthetic musk in cream by using SPME and then GC-MS, cream is chosen as it is the most common form of cosmetic product. (6) Cosmetic creams contains moisturizing, nutritional agent and also many lipophilic compounds. Synthethic musks have low polarity and it is also one of lipophilic compounds, which cause synthethic musks can be hardly be separated out from other liphophilic compounds. Cream samples must undergo extra cleanup steps such as by matrix solid phase dispersion method (MSPD) in order minimizes the matrix effect. Since water and isopropanol was used to separate synthetic musks from lipophilic compounds, supported liquid extraction will need to be used in order absorb water and remove interferences to give better purification. Tandem MS was used in this research in order to improve the selectivity and decrease the detection limit. This research which deals with dream shows slightly different in the preparation method compared to other GC-MS research, however, overall concept is still similar.

FINANCIAL MANAGEMENT Essay -- essays research papers

What do you understand by the phrase â€Å"stakeholder analysis†? Attempt a stakeholder analysis of an organisation that you are closely associated with. Introduction Stakeholder analysis is important for successful implementation of projects and/or strategic activities within any organisation. It is used to analyse the stakeholders in order to understand them and classify them according to their power, influence and interest. Stakeholders are people who have an interest in a commercial entity including those within the organisation and outside. These include the boss, senior executives, customers, suppliers, government, your co-workers, the team and others. All these people are important in the implementation and success of strategy. The tool stakeholder analysis is used to: - †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Identify people or groups and institutions that will influence your initiative †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Anticipate the kind of influence, positive or negative, these groups will have on your initiative †¢Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Develop strategies to get the most effective support possible for your initiative and reduce any obstacles to successful implementation of your program. The following are steps that may be followed in using stakeholder analysis: INDENTFY THE STAKEHOLDERS There is need to think of all people who are to be affected by the project or strategy, those who have influence or power over it or have an interest in its successful or unsuccessful conclusion. Stake holders for Delta corporation include:-   Ã‚  Ã‚  Ã‚  Ã‚  Government departments( Zimra, RBZ, Min of industry trade and commerce, ministry of sports and culture)   Ã‚  Ã‚  Ã‚  Ã‚  Municipal authorities   Ã‚  Ã‚  Ã‚  Ã‚  Standards association   Ã‚  Ã‚  Ã‚  Ã‚  Customers   Ã‚  Ã‚  Ã‚  Ã‚  Employees   Ã‚  Ã‚  Ã‚  Ã‚  Management   Ã‚  Ã‚  Ã‚  Ã‚  Trade union   Ã‚  Ã‚  Ã‚  Ã‚  National employment council   Ã‚  Ã‚  Ã‚  Ã‚  Directors and shareholders   Ã‚  Ã‚  Ã‚  Ã‚  Suppliers   Ã‚  Ã‚  Ã‚  Ã‚  The community and the public   Ã‚  Ã‚  Ã‚  Ã‚  My family and extended family   &... ...nbsp;  Ã‚  Who else might be influenced by their opinions? Do these people become stakeholders in their own right? Talking directly to the stakeholders will help answer most of these key questions. For IT projects meeting the key stakeholders in a forum to review progress on the project is key to its success. Therefore a well drawn up project plan will ensure that there is enough representation of the stakeholders at the regular project review meetings. Identify those stakeholders that may try to bring to a halt or slowdown the successful implementation of the project. CONCLUSION In any project it is important to do a stakeholder analysis in order to be able to identify the stakeholders and prioritise them by power and their interest to the success of the strategy or project. Once you identify them there is need to fully understand what motivates them in this project and what might be done to get their much needed support, thereby reducing obstacles to successful implementation. There maybe need to dangle carrots in order to get buy in from key stake holders. Incentives and rewards goes a long way in motivating other stakeholders to get results oriented effort.
