Development and use of explosives over the past century Essay

Development and use of explosives over the past century - Essay Example The first record of the usage of it exists dates back to around early 1600s in China (Tanner, 2014). During this time, the black powder was usually used in Hungary for blasting purposes. Mostly the quarries used the black powder for mining purpose blasting. The next mention of the uses of black powder is found in the context of tin mine blasting in the countries such as England after which the black powder was adopted by the Switzerland for road construction (Kelly, 2004, pp.198). The first documented form of mention of the use of black powder was in the year 1605 when Guy Fawkes put barrels of explosives in the British Parliament to blow up the building and assassinate the then king of England, King James I. This incident was named the â€Å"Gunpowder Plot†. It was one of the earliest conspiracies to involve the use of explosives and the black powder. This conspiracy of assassinating the King was not successful as the person plotting it was apprehended beforehand and caught. Another mention of the black gunpowder is prominent in the history is during the year 1773 when the people who went on with the demolition gathered 150 pounds of black gunpowder to demolish the Holy Trinity Cathedral which was 700 years old and one of the most oldest church in Waterford, Ireland. Later a report was published in the then famous newspaper named The Irish Times that the entire church was reduced to rubble within minutes and this incident was accompanied with a deafen ing loud boom that shook the entire area. This incident is important in the history of explosives as it marks as the first successful attempt in which the explosives blew down an entire structure and caused mass collateral damage. America adopted the use of explosives for the demolition purposes almost as early as 1850s. It was during this time that San Francisco was torn by a continuous series of many great fires. The use of the explosives in this case was because the city council members wanted to

Preludes by T.S Elliot and Vitae Lampada by Sir Henry Newton Essay Example for Free

Preludes by T.S Elliot and Vitae Lampada by Sir Henry Newton Essay Reading both poems for the first time, there seemed to be no distinct or even vague similarities between the two poems, Preludes, by T.S Elliot and Vitae Lampada by Sir Henry Newton. However, after reading each thoroughly a few more times and carefully evaluating them, several key similarities and as always, differences, began to reveal themselves. Both Preludes as well as Vitae Lampada begines with a time introductory statement. Theres a breathless hush in the close tonight. From Vitae Lampada, and The winter evening settles down from Preludes. Both these sentences inform us of the time, a sort of evening, just after dark. The very next sentences from each poem are also similar. Ten to make and a match to win and With smells of steaks in passageways. These sentences are written by the poets to set a scene, as one would set a scene in a drama play, but in poetry, with words. These two sentences give us a strong visual image of what the rest of the poem is about. Ten to make and a match to win is similar to that of a game of cricket, and as in cricket, it gives a certain tension of the stakes, to win the match. Preludes With smells of steaks in passageways gives us a vision of a lonely passageway, with smells of steaks suggests that the person the author is describing could possibly be an outcast of society, wondering around the streets in evening. Vitae Lampada goes further into describing itself. And Its not for the sake of a ribboned coat, or the selfish hope of a seasons fame. -immediately tells us that what they are encountering in their match, what they need to win, is not a one man team, but rather the whole team working as one. Not for personal glory but for much higher stakes, for the entire team. Preludes now introduces a picture of a low, dirty place. The grimy scraps, of withered leaves about your feet. A grimy place, a dirty place, somewhere that is not well maintained, with stray withered leaves across the floor. The next few lines The showers beat on broken blinds and chimney pots. Once again an image of a badly maintained place, with rain beating on broken pots that are left behind. On the whole, a negative image. Vitae Lampada, is also setting in a negative image, an image of lost hope and despair. The sand of the desert is sodden red -Red with the wreck of a square that broke; A square, in this case is referring to a formation of troops. Sir Henry Newbolt is comparing the aspect of war, with a game of cricket and this extended metaphor has worked exceedingly well in managing to contrast and yet bring the two closer together. Sodden red suggests that a great many soldiers have died and their blood spilled across the battlefield. The next two lines, add deeper to the feeling of despair. The gatlings jammed and the colonel dead, And the regiment blind with dust and smoke The soldiers that Sir Henry Newbolt is referring to here is not in a bright situation, with their guns jammed, and their leader (colonel) dead, and the entire regiment of them blind in the dust and smoke, it is indeed apparent that a deep feeling of desolation is introduced. And, as in Preludes, a negative image is painted. Revolving around time appears to be the main theme in Preludes. The start of the second stanza the morning comes to consciousness, lets us know that the morning has come, after the evening in the first stanza. And time is also in the fourth stanza the conscience of a blackened street. could possibly mean after dark. And a few lines before, four and five and six oclock suggests that time is moving quickly. The final stanza of Vitae Lampada uses a few strong words possibly to reinforce its meaning. Every one of her sons must hear, and none that hears it dare forget. Her sons, this of course, means the countrys people and the strong word must hear, hear the patriotism perhaps? And dare forget. dare is a strong word, a threat even. Threatening them to remember their loyalty, and to never forget it. Vitae Lampadas last few lines, bring a sudden contrast, compared to the rest of the poem. The second stanza is an image of despair, but here, the final touch to the sense of patriotism is added. Bear through life like a torch in flame, and falling fling to the host behind. This sentence carries a great deal of meaning to the main theme of the poem. Bear through life like a torch in flame suggests that these troops, instead of hopelessness, now carry a symbol, a beacon of light. The torch, could be as a baton is passed on in a game of relay. As falling fling to the host behind. When a soldier falls in battle, his effort is not lost, not wasted, but instead, passed on to those behind, as they march forward, with the flaming torch. These two poems have indeed, very different ideas and themes, but they both have several things in common. For a start, both Preludes and Vitae Lampada use time description to allow the reader a window in which to see the rest of the poem. Both are describing, metaphorically, aspects of life. And they both, to an extent, use negative images to describe, to paint their visual images to the reader.

The Philippine Is Rich In Natural Resources

The Philippine Is Rich In Natural Resources Current environmental laws consist of P.D No.984 entitled pollution control law that declaring policy to prevent, abate and control pollution of water, air and land for the more effective utilization of the resources of this country. The government was the one in charge to determine the location, magnitude, extent, severity, causes, effects and other pertinent information regarding pollution of the water, air and land resources of the country, and to issue orders or decisions to compel compliance with the provisions of the decree. The commission was the one who give issue, renew, or deny permits, under such conditions as it may determine to be reasonable, for the prevention and abatement of pollution, for the discharge of sewage, industrial waste, or for the installation or operation of sewage works and industrial disposal system. The commission, by rules and regulations, may require subdivisions, condominium, hospitals, public buildings and other similar human settlements to put up appropriate central sewage system and sewage treatment works, except that no permits shall be required of any new sewage works or changes to or extensions of existing works that discharge only domestic or sanitary wastes from a single residential building provided with septic tanks or their equivalent. The Commission may impose reasonable fees and charges for the issuance or renewal of all permits herein required For Presidential Decree 984 otherwise known as the Pollution Control Decree of 1978 is a national policy aimed to prevent, abate and control pollution of water, air and land for the more effective utilization of the resources of this country. In this Decree of 1978, the commission may conduct scientific experiments, investigations and research to discover economical and practical methods of preventing water, air and land pollution. Also, the commission may cooperate with any public or private agency in the conduct of such experiments, investigations and research for given any international, national or other public or private agency for water, air and land pollution control activities, surveys or program. The commission may secure such services as it, necessary from other agencies of the National Government, and they make arrangements for the compensation of such service. The commission may also employ and compensate, within appropriations available therefore, such consultants, exper ts, and advisers, or assistants on a full or part time basis, coming from the government or private entities ,to carry out the provisions of this decree and may prescribe their powers, duties and responsibilities. Under the P.D 1152 this is the policy for the various aspects of environmental management such as air and water quality management, natural source development, land and waste management. It provides a program to environmental protection and management, with reference to policies and standards of noise, air quality, water quality, classification of water and waste management. the P.D 1152 this is the policy for the various aspects of environmental management such as air and water quality management, natural source development, land and waste management. And for the R.A 1990 also known as the Toxic Substance and Hazardous and Nuclear Waste Control Act of 1990 regulating the important, use, movement, treatment and disposal of toxic chemicals and Hazardous and nuclear waste in the Philippines. Under P.D 856 Sanitation code for the solid waste management in his area of production can be places the responsibility in the local government units. Hotel and Tourism Management is affected by the current environmental laws in the Philippines, in previous effective wastewater treatment can prevent serious illness among guests and staff members, and limit the number of serious complaints from guests who become infected after drinking or swimming in polluted waters. It will also reduce the chance of cancellations from potential guests. Now, Reduce, Reuse and Recycle. Minimize wastewater discharge by reducing water use. Use biodegradable detergents and cleaning agents that are compatible with the wastewater treatment technology. Recycle paper products from the office for wrapping other items. Reuse treated graywater for washing floors, flushing toilets and irrigating gardens and golf courses. Separate waste at the source, rather than having to go through all the trash after it is collected. For example, provide containers for recyclables in guest rooms and compost bins in kitchen work areas. Because of the Environmental laws that government provide, Hotel and Tourism Management can provide also the best service to the hospitality industry which they are not allowed to built a business without permitted of the government. Under the decree of 1978 they have the commissions to cooperate with any public or private agency in the conduct of such experiments, investigations and research for given any international, national or other public or private agency for water, air and land pollution control activities, surveys or program. This is for the safety of the guest or tourist which is for the benefit of others. Hotel and Tourism Management can help improve the current environmental situation in the Philippines Environmental responsibility makes ecological sense, because keeping the environment pristine means that tourists will come to appreciate and enjoy the natural beauty of the location of your business. Increasingly, environmental responsibility also makes financial sense. Gone are the days when going green necessarily meant making large investments in expensive technology. Simple waste segregation, for example, can drastically reduce an island resorts expenses in transporting garbage off the island. Encouraging guests to follow simple steps, such as turning off lights and recycling water, could mean saving thousands on a resorts water bill. . Encourage staff to become involved in volunteer projects such as beach clean-ups and awareness campaigns. Educate guests as to how they can make a positive contribution to local biodiversity conservation efforts. Every business aims for long-term feasibility, and tourism based enterprises are no exception. A prime tourist attraction is a place that is full of life and abundance, a place where visitors can relax and feel that all is right with the world-a place they would pay hard-earned money to see and experience. Whether it means keeping the surroundings clean, making sure there is abundant water and electricity to use, or assuring guests of a nature experience they will not forget, maintaining a tourist destination means sustaining the life around it, and carrying out responsible operations that will make such sustenance possible. It takes only a few simple steps, the involvement and commitment of the people concerned, and a few adjustments in existing working and management systems to make environmental awareness a habit. Its a habit that is good for the soul, good for the community, good for Mother Nature-and happily, also good for business. Hotel and Tourism Management can improve the current situation of the environme nt in the Philippines by guiding the guest or tourist to become more efficient. Hotel and Tourism Management can help through orient the guest or tourist for them to know or understand the preservation of environment. To educate others, encouraging that environment is important. The conservation can enhance a places reputation among guests, other individuals and groups concerned about the environment. Supporting conservation efforts can generate positive publicity and improve relationships with local people and organizations. Hotel and Tourism Management can help improve the current situation in the Philippines by promoting the environment to become more clean and green, preserves the generation as the inspiration of mother nature. Hotel and Tourism Management can help the environment situation as a role model to our industry, to promote to others the need of our environment and for our everyday life.

Investigating the effect of Temperature on the reaction between Sodium Thiosuphate and hydrochloric acid :: GCSE Chemistry Coursework Investigation

Investigating the effect of Temperature on the reaction between Sodium Thiosuphate and hydrochloric acid  · Planning I am investigating the different temperatures on the reaction between Sodium Thiosuphate and Hydrochloric acid. The factors I could investigate would be temperature, concentration and substances. I have chosen to investigate Temperature. I predict that the higher the temperature the more rapidly the cross would obscure. This is because the higher the temperature the more often the particles collide and react, when the particles collide more often they would collide harder because they have more energy, making the collisions bigger and faster, the collision success rate is higher. I will make my investigation a fair test by keeping the quantities of the Hydrochloric acid at room temperature and Sodium Thiosuphate heated as accurate as possible. Also make sure the stop clock is started at the same point each time a measurement is taken. I will carry out the investigation by: 1. Set up the Diagram 2. Put the test tubes of Sodium Thiosuphate into the beaker above the Bunsen burner 3. Put a thermometer into it 4. Remove the test tube once its reached the desired temperature and pour contence into the empty beaker 5. As you begin to pour the test tube of Hydrochloric Acid contence into the beaker start the stop clock 6. When the cross on the paper becomes obscured stop the clock and record the result 7. Rinse out the beaker where the reaction took place 8. Repeat with five different temperatures, using ice to cool down the Sodium Thiosuphate, and repeat it all twice. The equipment I will use is:  · Hydrochloric acid  · Sodium Thiosuphate  · 2 x Measuring cylinders  · 2 x Test tubes  · stop clock  · 2 glass beakers  · 2 thermometers  · Bunsen burner  · water  · tripod  · heat mat  · gauge  · paper with pencil cross I will make sure my results are accurate by referring to graphs, e.g.: if one point is greatly out of alignment, it should be repeated. Also I will make sure that the meniscus of the hydrochloric acid and Thiosuphate is flat and not to one side of the test tube or measuring cylinder. I will take five measurements with a 10 gap interval and I will repeat this twice and take an average to make my results more accurate. Back ground Research - Trial Experiment I conducted a trial experiment to find out the correct quantities of sodium thiosulphate and hydrochloric acid for the main experiment. We were aiming for the cross to disappear in around one minute. We found the more hydrochloric acid the slower the X disappeared.

Engineering codes of ethics, case scenarios, and societies that enforce them Essay

Ethics can be defined as a branch within the wider field of philosophy whose main concern is addressing the issue of morality. Morality as a concept seeks to justify actions as good or bad, right or wrong and whether such actions are justified and virtuous. Ethics in itself is divided into many categories which normally vary to suit the issue at hand. From a general perspective, ethics can be widely grouped into theoretical and practical ethics. The theoretical aspect is concerned with theoretical meanings of moral propositions and the manner in which their truth values can be ascertained. The practical aspect of ethics seeks to address the possibility of achieving moral outcomes in a given situation (Luegenbiehl, 2003). Engineering ethics in this context is part of applied ethics that is skewed towards the examination and the setting of standards concerning the duty of an engineer to the general public, how they should attend to their clients, their duty to their employer, and their obligation towards enhancing and maintaining the moral integrity of the engineering profession. Engineering as a profession is very diverse in terms of the possible branches one can venture into. This diversity make some of the engineering fields share only very limited principles. While most of these disciplines tend to complement each other, these engineers are bound to work in different environments. As such there cannot be a unifying code of ethics for the whole engineering fraternity. Ethical codes in this profession are largely dependent on the exact field of specialization and the jurisdiction of practice. Another factor that comes into play is whether an engineer is providing consultancy service to his clients or the engineer is an employee of a given manufacturing enterprise (Colby & Sullivan, 2008). In most countries, the engineers who attend to their clients are normally referred to as professional engineers and are usually licensed. They abide by codes that ensure professional ethics and to a larger extent governed by a number of statutes. Their counterparts who practice in the manufacturing industry have to abide by certain laws, key among them being whistle blowing and also the law of product liability. Their practice leans more towards business ethics as compared to engineering ethics. Professional engineers are usually in private practice and are always responsible for drafting some of the codes of ethics that govern their profession. Engineers who practice in the industrial sector do not enjoy accreditation by the relevant government agencies. It is an arguable fact that despite the field and sector of practice, these engineers face similar ethical issues. Similar in the sense that they share the same root causes but only change slightly in form depending on the discipline and the sector of practice (Luegenbiehl, 2003). Engineering societies have for a long time drafted their own codes of ethics. These codes of ethics have undergone a series of refinement over time in a bid to make them more viable to overcoming ethical issues. Such codes of ethics usually act as general guidelines since ethical issues are very diverse and as such some of these codes have to be adjusted to suit the situation at hand. In the United Kingdom, a notable example is the ‘Institution of Civil Engineers (ICE)’, which chose to incorporate its ethical codes into the standards of conduct. The code of ethics in engineering basically seeks to ensure the wellbeing of the public, the clients in the case of a professional engineer, the employer for the engineers who practice in the industry, and for the enhancement of the moral integrity of the engineering profession (Colby & Sullivan, 2008). Any engineering profession is susceptible to a number of risks some of which may be detrimental to a wider section of the population. With this risk in mind, the first aim of an engineer is to ensure the safety and health, not only of the general public but also for themselves and their workmates. Engineers are required to subscribe to principles that ensure sustainable development in the course of their undertakings. Since the engineering profession is very diverse, an engineer who may be very competent in his field of specialization may not be able to achieve much in another line of engineering. For most of the engineering societies around the world, there are basic ethical codes that they seem to share in common. A code of ethics in the field of engineering always restricts engineers to stick to their areas of specialization. This is to avoid exposing himself and the general public to the imminent danger. An engineer is required to speak the truth on the technical aspects of a job and maintain a professional relationship with the employer or his client. Conflict of interest is a sure way to compromise and as such should always be avoided by an engineer. An engineer is supposed to safeguard the integrity and the interest of the engineering profession. In as much as an engineer is supposed to advance career wise, they have an obligation of ensuring professional growth for their juniors. According to the law of whistle blowing, an engineer is more obliged to safety than he is to the client or to his employer. This law requires the engineer to report cases where their employers or clients fail to follow their directions and in the process are exposing the public to potential danger. In some instances, some the relevant authorities fail to take action and this may end up in the engineer going public (Luegenbiehl, 2003). The most notable cases of disaster in the field of engineering have been caused by both technical and ethical issues. While some of these accidents have been due to technical aspects and design inadequacies, others have been due to inefficient management culture. Some of the cases that have been established to have an ethical dimension on their occurrence include the Chernobyl disaster, Bhopal disaster, Boston molasses accident, Johnstown Flood, just to mention but a few (Pfatteicher, 2001). Chernobyl disaster was an incident that took place in Ukraine, and it involved the meltdown in a nuclear reactor plant. This accident was to a larger extent blamed on human error. The personnel were blamed for using a limited ‘operational reactivity margin. ’ The disaster caused to the people living within the neighbourhood was immense in gravity and most of the effects were of a long term nature. The mental health of the people was extremely affected; cases of cancer were later reported to be rampant in the area. All these effects came about due to the irradiation of the area by radioactive material. The workers were also affected with more than thirty losing their lives within a span of three months from the time of occurrence of the disaster. An advisory group that was later formed to look into the cause of this disaster blamed the people who were responsible for the design of the power plant. They failed to consider certain pertinent aspects of the design which could have prevented such an occurrence or which could have ensured that the accident did not proceed to reach the level it did. It was realized that in the course of preparation and subsequent testing of turbine generators, it was done without the incorporation of systems that were responsible for technical protection. This was viewed to have been a breach of the safety provisions that were required for the actual technical exercise (Pfatteicher, 2001). Some of the most outstanding organizations that are concerned with engineering ethics include the ‘Institute of Civil Engineers (ICE)’ in the United Kingdom, the ‘Canadian Society for Professional Engineers,’ and the ‘National Society of Professional Engineers (NSPE)’ which have been seen to be championing for the upholding of ethical practices within the engineering field. The reasons for their establishments are to ensure that engineers in private practice, the government and in the manufacturing sector are able to subscribe to a common code of ethics within a given jurisdiction. Such bodies have certain punitive measures to their members in cases where ethics appear to have been sidelined in making decisions. To ensure that engineers adhere to such codes set by these organizations, it is mandatory to be registered with certain bodies within given jurisdictions to practice as an engineer (Haws, 2001). There has been a general drift towards formulating an all encompassing code of ethics for all engineers throughout the world. This has been noted by the fact that the codes formulated by most societies throughout the world appear to be having certain similarities. While this appears to be a very noble idea, some room and allowances will have to be allowed to accommodate the different cultures in the world. It is deemed that developing a set of common ethical codes and supplementing it with additional entries that regard the cultural setting and the exact field of specialization within engineering. The codes should be set out in such a manner that no confusion can be reported within a given jurisdiction (Luegenbiehl, 2003). References: Colby, A. , & Sullivan, W.

Playing Sports Teaches People Lessons About the Life. Essay Example

Playing Sports Teaches People Lessons About the Life. Essay Example Playing Sports Teaches People Lessons About the Life. Essay Playing Sports Teaches People Lessons About the Life. Essay Playing sports teaches people lessons about the life. Nowadays, a large group of people are crazy about doing sports with other zealous fellows. They always keep themselves occupied with all kinds of sports instead of lying in sofa, watching soap operas. I am a loyal advocator to this passionate life style. While possessing a good health, beneficial classes of life are extra gains of doing sports. Doing sports constantly can steel people’s willpower and teach them the lesson of persevering in everyday life no matter how tough the situations are. For instance, Lionel Messi, my favorite football player, no one could believe that he was diagnosed with a growth hormone deficiency and we almost miss a superstar! However, his persistence and intense love for football kept him going on without hesitation and nothing could stop him from becoming an excellent player. Ultimately, the sporting director of Barcelona had been made aware of his talent and led him to a superiorly shining life. Now he has received FIFA World Player of the Year nomination in 2009 at the age of 21. This incident gives me a full understanding of the fact that how unbelievable results sports may bring to people. In addition, sports guide people to respect rivals regardless of the results. Also, no matter how strong you are and maybe your opponent has no chance to win at all, respecting opponents still remains its essential place. In 2010 Africa FIFA World Cup, when North Korea which at the bottom of the ranking list encountered Brazil, which ranks No. 1 in the world. Brazil showed the characteristic of a world-class team. They tried hard as their competitors were equally strong as them and spoke highly of North Korea’s presentation after the game. In sum, sports really enable people to own the quality of respecting opponents, which makes it unique compared to other things. Another vital class we can learn is accepting defeats or victories, it is a fundamental part of competition and it is unavoidable for each participant. That is just the most appealing part of sports. Team members should not blame their partners for anything as long as he puts all his heart into it. Facing failure calmly and embracing success modestly are the experiences of life that sports give us. Considering all the analysis above, we safely come to the conclusion that doing sports indeed benefit us a lot in varied ways. I insist that in the future a large range of people will participate in sports and obtain knowledge of life.
