Tsunami Essays - Physical Oceanography, Water Waves, Natural Hazards

Tsunami When one thinks of all the natural disasters, that could effect the Maryland and Washington D.C. area they often think of hurricanes and snowstorms. They often forget about the possibility of a tsunami. A tsunami, often referred to as a "tidal wave", is a wave train, or series of waves, generated in a body of water by an impulsive disturbance that vertically displaces the water column. Being located on the Atlantic coastline the possibility of a tsunami is very much a reality. But have you ever wanted to know what can cause waves of this magnitude? Tsunamis are usually caused by earthquakes that occur on the seafloor or in coastal areas. The energy generated by the earthquake is transmitted through the water. In deep oceans the energy in these sea waves can travel unnoticed because the wave height may be only twelve inches. When this energy reaches the shallow waters of coastlines, bays, or harbors, it forces the water into a giant wave. Some tsunamis may reach heights of 100 feet or more. Rarely but possibly cosmic collisions can cause a tsunami. Things like meteors or asteroids impacting in the middle of the ocean will disturb the water from above. These cosmic bodies will start a tsunami on its destructive course. No one has actually witnessed such an event, except in the movie Deep Impact. But computer simulations show that these giant tsunamis are indeed possible. Lastly, submarine landslides, which often accompany large earthquakes, can also disturb the water as sediment and rock slump downslope and are redistributed across the sea floor. When these large amounts of dirt, mud, or sand slides into the ocean it often generates an uplift in the water causing a tsunami. Earthquakes, cosmic collisions, and landslides are just few causes of a tsunami. Even though the Maryland and Washington D.C. area are more likely to have a hurricane or a snowstorm, we must not ever forget the constant threat of having a tsunami.

Physics Archimedes Principle Lab Report Essays

Physics Archimedes Principle Lab Report Essays Physics Archimedes Principle Lab Report Paper Physics Archimedes Principle Lab Report Paper The spring constant of the spring was multiplied by the displacement, and then divided by gravity. I Volume of Lead gel . 0 g/ coxcomb=9. Xx-4 gate volume of the rod was found by dividing the mass of the zinc rob and the density of the fluid (water). I Density of density of the unknown squid was found by dividing the mass of zinc rob by the volume of the zinc rod. I Discussion: The objective of this experiment was to measure the density of a solid and an unknown liquid by using one of the oldest principles, Archimedes principle. For part A of the experiment, we were able to use the spring constant found from the previous lab, in order to help determine the change in mass and volume of an object, and the density of an unknown liquid. The spring constant that was found from the previous lab was 0. 023 N/m. In part B of the experiment, we were able to determine the change in mass of he lead rod from the air to the water and the volume of the lead rod. After conducting five trials, we were able to find the change in mass of the lead rod by using the spring constant formula of F=xx. After modifying the formula to solve for mass, we were able to find the change in mass for each trial by multiplying the spring constant and displacement of the lead rod in air versus water, then dividing by gravity. The average change in mass was found to be 9. XIII-g. Once we had found the mass of the lead rod, we were able to find calculate the volume of the lead rod by modifying the buoyancy force formula to solve for the illume of the object. Find that formula, we divided the mass of the lead rod by the density of water as shown in the table of literature. The average volume of the lead rod was found to be 3. 22 cam. In part C of this experiment, we were able to determine the change in mass of the lead rod from air to an unknown liquid and the density of the unknown liquid. We used the same method in part B to calculate the change in mass of the lead rod. The average change in mass of the lead rod in the unknown liquid was found to be Since the volume of an object does not chang e when submerged n various liquids, we were able to use the average volume of the lead rod found in part B. Then, we were able to find the density of the unknown liquid by dividing the mass of the lead rod by the volume of the lead rod. Average density of the unknown liquid was found to be 1. 344 g/cam. Since the unknown liquid had an aroma of rubbing alcohol, we hypothesized that the unknown liquid was a mixture of rubbing alcohol and water. Using Archimedes principle, our hypothesis can be supported since the average density of the unknown liquid was 0843 g/ml. An alternative method for this experiment would be to set up he beaker so that the liquid level would be completely leveled, versus when a person lifts the beaker with an unleavened liquid level. Away a person could do this would be to place a book under the beaker with a leveled liquid level, so that the lead rod is equally and fully submerged in the liquid. Conclusion: The objective of this experiment was to determine the mass and volume of an object and the density of an unknown liquid using Archimedes Principle. For part A, we used the spring constant from the previous lab to help determine the mass of the lead rod in part B. The displacement of the lead rod from the air to the eater was found in order to help determine the average mass of the lead rod. The average change in mass of the lead rod from air to water was 9. Xx 0-g. The average volume of the lead rod was 9. Xx-CM. In part C an unknown liquid was used. A similar method was used to determine the average change in mass of the lead rod in the unknown liquid, which was found to be 7. Xx-g. Since the volume of an object does not change in different liquids, the volume of the object found in part B was used in part C to help determine the density of the unknown liquid. The density of the unknown liquid was 0. Egg/ml.

Family Concept Essay Example | Topics and Well Written Essays - 750 words

Family Concept - Essay Example Legitimization of children born is of course a universal criterion of marriage. Another factor related to the subject marriage is 'legal paternity'. Dr. Edmund Leach in Europe is of the opinion that no definition could be found that would apply to all the institutions which is commonly accepted as marriage. He referred to ten classes of rights which are related with the word marriage. He is flexible in his approach and states "we ought to feel free to call 'marriage' any institution which fulfils any one or more of the selected criteria". Dr. Leach cites the case of Nayar, the Kerala person in Kerala community. His marriage is not accepted as traditional marriage but a "relationship of perpetual affinity" between linked lineages" (Gough 1955a). The ritual husbands of Nayar girls had no obligation to the brides after the ritual was over. The ritual wife also has no obligation except observing pollution rites at death of the ritual husband... The children born to the woman after marriage have no notion of paternity. . The marriage was basically exogamous with matrilineage character having allegiance to the family of head of the village which might be patrilineal Nayar... Such traditional scattered groups all over the world lost the cohesion of tradition later but kept together by thin thread of kinship. What is the actual family scenario in the western world today The institution of marriage is present but the divorce rate remained as high as 50%. The rate of marriage is coming down and the system of co-habitation started in which men and women live together without marriage. The status of family in this new system is very weak... Couples who once might have wed and then divorced now are not marrying at all. Co-habitation is never good for children because it increases family instability. Cohabiting couples have twice the break up rate of married couples only because there is no family bond between the couples. 40% of children in USA come under this fold of loose family set up. 8.1% of US coupled household are made of unmarried but heterosexual partners. The percentage of children who grow with both biological parents is the lowest at 63%. The divorce rate in USA being one of the highest the family status in this country is the weakest with the highest rate of solo parenting. In this type of a weak family concept and social scenario any university would remain confused about promotion of a well-defined family set up. Therefore my concept of a family set up would be one where there is unity, love and peace among all the family members to promote the objective of everybody's life. Generation has due recognition in any society and family but not from the marginal point of view as it was earlier...We often hear about generation gap. The emergence of global generation that started in 1960s has world wide repercussions today with major development in new electronic communication and international consciousness. The future generation will be uniquely influenced by web technology with the introduction of social networking services like MySpace, social bookmaking sites like Yahoo's del.icio.us, and peer to peer social networks like the blogosphere and the cell phones... Today the word

Personality Traits - Essay Example In addition, it is also true that I tend to perceive life as rosier than it is sometimes, but I do not think this is bad. On the contrary, if one willingly chooses to observe life as a unity of the good and bad, manages to focus on the good and learn from the mistakes that represent the bad, he is on the right path to a full and rich life of personal satisfaction and gratification. Aside from this, my problem solving skills have also been perfected in the sense that, unlike most people who get paralyzed when they are confronted with a difficult situation, I stop and think it through carefully. I do not waste time bothering myself with scenarios that could have been, and â€Å"if only he/she did not do it, now I would not be in this predicament.† I find this type of thinking detrimental to the process of solving the problem in question. A happy mind is a healthy mind and there is nothing that a healthy mind cannot

Critically evaluate theoretical explanations of motivation that we Essay - 1

Critically evaluate theoretical explanations of motivation that we have learnt about in this module week 4 lecture - Essay Example tors within an individual and the environment in ways that determine the nature of outcomes and the level of attachment between the agent and the task. Content theories are concerned with the causative agents of behavior. The humanist theory explores the subject of motivation alongside Maslow’s theory of needs. The processes of motivation, according to the theory depend on the sequential pursuit of needs in accordance with the hierarchy determined by Maslow (1970). Understanding of humanist needs must begin with the comprehension of the processes of adjustment, which takes place whenever some form of inequilibrium occurs. In general, such processes entail a determination of a range of issues that affect the state of equilibrium of needs. Essentially, groups and individuals will seek to adjust themselves and situations around them in ways that minimize the effects of stress. Motivation, in the sense of humanist theory, is understood as some kind of kinetic force the offers the necessary propulsion in an individual or a group towards the attainment of some specified goals, which are consistent with their needs (Ahlstrom & Bruton, 2009, p. 61). One of the characteristics of motivation is that it seeks the determination of goals based on the particular needs of the individual. The pursuit of motivation is considered a subject endeavor arising out of the unique needs of the individual (Miner, 2007, p. 40). For instance, an individual aspiring to attain a certain level of professional competence will invest more efforts in training and practical experience in a consistent and orderly manner. On this score, it becomes appropriate to consider the fact that some of the goals achieved through the efforts as understood within the humanist theory are suited for particular motives and limited to certain subjective interests. In essence, the humanist needs work in such a manner that individuals will seek to satisfy some pressing basic needs before focusing on other kinds of

They Travel For Sightseeing For Tourists

They Travel For Sightseeing For Tourists Tourists. They travel for sightseeing, recreation, visiting and non-business activities. They want to learn about the customs, the history and the language of every place they visit. They usually travel in groups. We have to provide them with any information that may need about the area, the transportation, any local events that may take place in the surround area etc. and to make them feel at home. They are looking for recreational facilities, food and beverage services and interior design. That kind of guests are usually very price sensitive. Families. They usually travel on weekends and they want a short break from their everyday routine. They are looking for a quiet place to relax and enjoy their time. They are looking for recreational facilities, food and beverage services and the hotel should offer baby-sitting facilities, special meals for kids and an animation team. The elderly. They cant look after themselves as the years pass, so they are looking for a hotel with pleasant and friendly environment. We have to be kind and patient with them and to look after them without giving them the impression that we behave on them like children. Business travelers. They are almost the most important travel market for many city hotels and this is the reason why the hotels who target this market have designed specific products and services to cover their needs such as a quiet environment. Most of business travelers do not like to stay in hotels because after a hard day they prefer to stay in a quiet place to rest and to relax rather than a noisy room in a hotel. Another thing that they worry about is their messages and how well the hotel can handle this. We have to offer them facilities such as: meeting space, computer services, internet access etc. Business travelers are usually not very price sensitive and often utilize hotels food (especially room service), beverage and recreational facilities. They considered desirable and profitable market and is an important segment because of its steady level of demand at high room rates. Delegates. Meeting and conventions usually attract hundreds of people and this is the reason why we have to convince the meeting planner to choose our hotel. They are looking for fast service and they dont like to stay in queues. Meeting and conventions have to do with people who attending seminars, trade association shows etc. The length of stay for meetings ranges from 3 to 5 days. We have to provide them a conference center for the meetings, computers services, internet access and when we have a large group some discounts are necessary because in this way we can attract them to visit again our hotel as leisure travelers. We have also to provide them in house banquet and cocktail receptions. Describe the importance of welcoming a guest and the techniques that should be used. Always the first impression plays the most important role when a guest arrives at the hotel and influences the rest of his stay. The receptionists should always be warm and friendly when they checking in the guests to make them feel comfortable like at home. A good greeting can make a guest feel better. A well-spoken receptionist by giving a smile of welcome from a charming succeeds to create a warm and friendly atmosphere also has to be able to recognise the guests personality and to adapt in order to satisfy the guests expectations. Some techniques that should be used are: keep eye contact and smile, be clear in your speech and use a pleasant tone of voice, avoid speaking too fast or too slow, use the guests names, always be polite and kind, always start and end with a positive note, always be: friendly, interested, helpful, never mechanical, never different and never impatient. There is a big possibility that when a guest leaves from the hotel with a good impression he will come b ack and he will be a good advertiser for our hotel. Describe the guest registration process and explain its importance. We have to follow several steps for the registration process. The guest registration process begins with the pre-registration activities which accelerate the registration process, guests can verify personal data and the time of the check-in the guests have only to sign the registration form. When the guests arrive we greeting and welcoming them and after we create the registration record and verify the guests identity name, the permanent address and the telephone number, the date of arrival and the departure, number of registered persons, method of payment, passport and signature. After this process we assign the room rate and we establish the method of payment. We continue by issuing the room key and ask the guests for any special requests. When all these finish we escort the guest to his/her room. The guest registration is important because by completing this form let us know who stays in our hotel, especially during in an emergency situation. With guest registration we can also learn if a guest is a repeater, if he has already visited another hotel of our company. Also with this form we can find some information about the guest needs (in case that he is repeater), such as smoking or non-smoking room, allergies, any special requirements that he use to have. Explain what guest history files are and why hotels keep them. Guest history files are files in which the management records important information of all his regular guests and show any special requests and expectations that a guest have in case that the guest has stay once at the hotel. Hotels use to keep guest history files because these files help the management to improve the guest service and also to remind personal data of its repeater guests. These files contains details of credit cards, the date of the first stay, how many times a guest has stay at the hotel and how many nights, how much the guest spent in the different departments, how much he has spent on each stay and the room types that he prefers to stay. Also these files record any special needs (newspapers) and preferences that guests might have. Explain up-selling and the techniques that can be used Up-selling is the use of specific words and phrases that will lead the guest to buy something he would not otherwise have bought. We can succeed in up-selling if we think that is a way of helping out the guest by offering him a satisfying solution to cover his needs. Some techniques that we can use when we selling a room are: Qualify the lead. Asking questions and try to understand exactly what your prospective guest is looking for, keep an eye contact and let him talk without interrupt him. Built a relationship and make your guest feel comfortable. By doing this you create a friendly atmosphere and gives you the advantage for a better sale. Make a presentation of your property. Provide brochures and prospects for what you offer and convince your guest that you know what you sale. You have to know your product inside and out and also to know your market area and your competitors rates. Close the sale by asking for the sale. Dont be in rush for giving any discounts that probably your guest will ask, just focus on value. Follow up the sales visit by sending questionnaires. This is a good way to find out if your guest left satisfied from your hotel and gives an indication that this guest might return in the future and also bring and other guests with him. A satisfied guest is an advertisement for our hotel.

Legal Development of Abortion Essay -- Argumentative Persuasive Topics

Legal Development of Abortion      Ã‚  Ã‚   This essay traces the development of abortion law in English and American society up to the time of Roe v. Wade in 1973. Beginning with Biblical citations, the essay researches the Early Church Fathers on the issue; the American colonies; developments of the 1800's which caused change, and so on.    Up to the time of the Protestant Reformation, the English society inherited its traditional anti-abortion law from the Church practice of 1500 years standing; which belief began even before Christianity as part of the Old Testament Jewish belief. The Old Testament tells us: "Death was not God's doing, he takes no pleasure in the extinction of the living" (Wis. 1:13). What is willed is life, and in the visible universe everything has been made for man, who is the image of God and the world's crowning glory (Gen. 1:26-28). In the Christian tradition, the Early Church Fathers taught in The Didache, perhaps the first Christian catechism from 70-90AD, the following in chapter 2, verses 1-2: "The second commandment of the teaching: You shall not murder. You shall not commit adultery. You shall not seduce boys. You shall not commit fornication. You shall not steal. You shall not practice magic. You shall not use potions. You shall not procure [an] abortion, nor destroy a newborn child." (Ju rgens vol.1,p.2)    The colonies inherited English Common Law and largely operated under it until well into the 19th century.
