Time Travel - Essay Example And having thought what to do, we can only do it now: while the time for action is future we can only await it, and once it is past it is too late. When it comes to time travel, the perception of difference somewhat diminishes, according to various scientists theories presented in various ways we conclude that most of them agree with the notion that in order to travel back in time one has to travel faster than the speed of light. Only in such condition one can travel in time. Along with the speed of light, there are other three factors that are considered for a person in order to travel. Those factors or four elements on which time travel is based are considered at the very core of science fiction, which are: Foote has his own unique perception according to which traveling whether it be the future or the past is reasonable to justify and can be universally accepted by the judgment that a person is always involved in traveling all the time, every minute and at every second and particularly in his sleep because as we sleep our consciousness takes a several hour-long leap into the future. It is no wonder that this scenario has a respectable, if dateable, past in the literature of science and fiction. But nothing, nothing except dream and memory, stands in relation to travel to the past as sleep does to travel to the future. Travel to the past takes all customary notions of cause and effect, as Foote believes in the laws of thermodynamics. (Foote, 1991, p. 9) which suggests, "heat is a form of energy that is in motion". Let us examine this quotation what Foote has said. Heat is a form of energy and so is the man. A living energy in the form of meat and flesh. A man if moves in motion obviously generates and radiates energy and if a man travels faster than the speed of a light it is for sure that he would wake up in an environment which is quite old and ancient for him. Faster than light travel No doubt Foote has related human capabilities with those of the speed of light. Here is the theory presented by Foote based upon FTL travel first: it is true that the physicists of the tribe have devised a mathematical fiction called the tachyon, which, if it exists, must travel faster than light. Greatly simplified, the logic runs like this: in the universe we observe, we postulate the existence of tardyons, particles which must travel more slowly than light, and luminons, which always travel at precisely the speed of light. The more energy one puts behind a tardyon, the faster it travels and the heavier it gets; but as one approaches the speed of light, vast increases in energy are required to accomplish minuscule increases in speed. Only an infinite amount of energy which is not available to us in this universe will suffice to bring a tardyon to the speed of light". (Foote, 1991, p. 9) There is indeed an asymmetry in respect of past and future in the way in which we describe events when we are considering them as standing in causal relations to one another; Macbeath explains this as it reflects an objective asymmetry in nature and thinks that this asymmetry would reveal itself to us even if we were not agents but mere observers. It is indeed true, that our concept of cause is bound up with our concept of intentional action: if an

Petrophysics Essay Abstract The South Tapti gas field, located in the Arabian Sea off the western coast of India, has been on production for the last three years. Drill Stem Tests (DST) conducted in five zones in the first appraisal well showed high sand production in all the tests at drawdowns as low as 20 psi. Due to the unconsolidated nature of the reservoir sand, it was decided to gravel pack all future wells. Initially, the High Rate Water Pack (HRWP) technique was used on 13 completions including some stack and selective completions. Due to a change in the drilling fluid to an oil based mud (OBM) system and the higher damage associated with the it, it was later decided to switch the gravel packing technique to ‘Frac and Pack’. This involved creation of a small frac to bypass the near wellbore damage using a gel-based fluid, followed by gravel placement using the HRWP. The Frac Pack technique was tried on 10 completions. Extensive production and pressure data collected on the above completions show that the ‘Frac Pack’ technique has led to a decrease in the mechanical skin by almost 70 %. More importantly, it has also been responsible for decreasing the Rate Dependent Skin Coefficient, D, by 50 %, which has a greater impact on the well productivity since these wells are produced at average rates of 25 MMSCFD. This paper describes the gravel packing techniques used in the South Tapti gas field, their evolution and the results achieved. Inroduction The South Tapti field, located off the Western coast of India, is represented by a series of alternating sand and shale sequences. The upper reservoir intervals are dominated by tidal-bar and channel sands deposited in a deltaic environment while the lower sands represent incised valley deposits consisting largely of alluvial/fluvial channels, tidal bars and tidal creeks. The exploratory wells drilled in the field indicated strong sand production tendencies due to the unconsolidated nature of the reservoir rock. This was corroborated by extensive testing of the first development well when all the five zones tested produced sand even under extremely low pressure drawdown conditions. The completion policy for the field focused on preventing sand ingress while minimizing the near well-bore damage inherent in any sand control application. The early development wells were gravel packed using the high rate water pack (HRWP) technique. These initial completions were highly successful in preventing sand production but also induced significant damage in the process. The problem was accentuated when the drilling mud system was changed to an oil base system in an attempt to offset recurrent drilling problems arising out of unconsolidated sandstone and presence of reactive clays. This called for a change in completion philosophy in order to ensure that the wells retain high productivity with effective sand control. Geologic and Reservoir Characterization The South Tapti field is localized by a broad SW-NE trending, doubly plunging anticline. The field has up to 13 different Oligo-Miocene gas bearing sands, separated by shales. The reservoir sands were deposited in both incised valley and deltaic settings. Reservoir sands within incised valleys consist of alluvial/fluvial channels, tide-influenced channels and tidal bars. The channel sands typically are the cleaner sands with excellent porosity permeability and up to 20 m thick, whereas the tide-influenced channels and tidal bars are shalier, with more modest porosity and permeability. CLAY MINERALS 1. Abstract: Tapti Basin in Surat Depression, Bombay Offshore is characterized by entirely siliciclastic succession. The cores and cutting samples, and wireline logs provide important information about the stratigraphy, basin fill, mineralogy, source and reservoir rock characteristics. Well under study is located in South Tapti sub-basin and contains gas-bearing sandstone within Mahim Formation of Late Oligocene age. The cuttings and cores have been megascopically examined and with the aid of electrical log data, the litholog of the well is prepared. The study involves XRD and major element analysis of selected samples. The XRD and digital log data from Natural Gamma Sepctrometry (NGS) log indicate that montmorillonite is the major clay mineral present in the upper part of the succession, whereas kaolinite present in the lower part (1868 m MD to 2427 m MD). Kaolinite is apparently formed by early stages of burial diagenesis, whereas montmorillonite is a weathering product of the Deccan Basalt. Interpretative lithology from the well log response shows that reservoir sandstones have developed within the depth interval of 1865m TVD to 1945 m TVD within dominantly shale lithology. Reservoir sandstones are semiconsolidated, medium to coarse grained and moderately well sorted. Quartz is the dominant detrital component in all the sandstones. Pay sands are quartz arenite whereas non-pay sands are quartz wacke with varying amount of clay matrix. Kaolinite in the reservoir section reduces the permeability of quartz wacke, but enhancing porosity in microlevel. Carbonate, siderite and iron oxide are main cementing material. Major element data showing that clastic sediments were delivered to the basin possibly by the Proto Tapti river but they may be having dual source of origin. The discriminant functions of Meyer and Nederlof, 1984 has indicated that the studied formations do not have source rock potential.

Green Living: What Is It?

Green Living: What Is It? The earth, as we know it is deteriorating in ways more than one. In order to set it right and restore the balance of events, we need to take an initiate and change our lifestyles to support the planets health. There are many ways by which you can also start to live greenly. The actual meaning of green living is to live in a way that is favorable to the planet and does not harm, or use up any of its resources excessively. It shows that you care for your planet, and are willing to make an initiative to set things right. If one person starts to live in greenly, others will see the effort he is making and eventually start to follow his example. Because the condition of the planet is worsening day by day, it is important that we take an initiative right now rather than repent it later. The world is deteriorating at a rapid rate, and it is all because of us. Many people dont give enough care to what they do, and these results in a rapid use up of the planets resources. For instance, we often do not give enough care to the electricity consumption of our house. There are many ways by which you can start green living too. However, in order to actually make an impact, we people need to realize the damages that we are doing and we all need to make a collective effort towards the betterment of this planet. One person can make a difference, but one person can set an example for others to follow. Some of the tips that we can follow in order to live greenly are mentioned below. The first thing that you need to do is to limit your energy consumption. There are many ways by which you can do that. Try to avoid excessive usage of your desktop computer, because a desktop computer uses up lots of energy that could otherwise be saved. For instance, you could just start to use a laptop, and if you dont have one, it is certainly wise that you buy one for yourself so that you can limit your energy consumption. Now, as mentioned, one person cant do anything or make an impact on the planet at all. However, imagine if every person in an area started to effectively use their energy and started to limit their consumption, then what would happen? Ill tell you, the planet would slowly start to heal itself because a load would be lessened and slowly the resources that are used in generating electricity would be lessened and this could be highly beneficial because at present we use large amounts of coal and other thermal resources to facilitate our stay on this planet. However, the rapid consumption of these resources, which are non renewable would want day result in the death of one of these crucial resources. For instance, if coal becomes extinct, then a lot of activity on this planet would cease to exist and we would just be searching for alternatives that might not be found so easily. However, if we start to use non renewable energy in our homes and start to take care of our planet, we could definitely make a small impact which might enlarge and the whole world might just join the go green movement. Article#2 Green Living- Time to go green: Summary Green living is the changing of your life style to set it according to the ways of the planet. By that, I mean that we need to make our stay more favorable in this planet so that we do not harm it in any way. There are many ways to initiate green living. In order to make your life a bit better and a bit greener, you need to take certain steps so that you do not harm the resources of this planet. The first step that you can include if you wish to start green living is efficient energy consumption. Many people dont realize that they waste large amounts of energy in various unnecessary things that could otherwise be saved. Electrical energy is made by the use of thermal resources and there are very few plants that make use of non renewable resources. Hence, the more energy you waste, the more thermal resources would be used up of the planet. If all these resources get used up, this could be very harmful for the planet in a variety of ways. At present, we are rapidly using the planets resources to facilitate and make our lives better. But, if we cut down on them, we could certainly make living on this planet a bit better and much greener. You can practice a variety of small things that could certainly save you a lot of energy which could otherwise reduce the load on the planet. If you have a car that runs on diesel or petrol, it would be wise to convert it to CNG, which uses compressed natural gas that is not harmful in any way to the planet. What happen when you use petrol or diesel is that carbon monoxide and carbon dioxide are released in to the atmosphere, which harms the planets atmosphere as well as the ozone layer of the planet. We need to take care of the planet, because we have certainly used it in a very harmful way. Other things that we can do and change if we want to live greener life are that we can cut down on our energy consumption. Some of the largest amounts of energy are consumed when people leave the lights of their homes on and do not bother to turn them off. The lights just keep on using energy even though they are not being used in any way. Therefore, it is always wise and highly recommended that you shut off the lights before leaving any room so that you can save on energy. A go green movement has been initiated by the people, and it is gaining a lot of popularity as more and more people are changing their lives and living methods so that their stay on this planet becomes favorable for them as well as for the planet. You need to take care of the planet, because if we dont then there is no one else who will. We need to practice just a few things which would certainly not restrict our lives in any possible manner, but would certainly allow the planet to heal itself and become a better place for everyone to live in. Start green living, and support the planet, because it never gives up on you. Article#3 Time to Start Green Living! Summary: Our planet is slowly dying, and if we dont do anything about it soon enough, it would eventually begin to deteriorate and everything would be used. The world would become a barren place without any resources. We need to cater to the needs of our planet, and we need to change our life styles so that it becomes beneficial to the planet. We need to become much more eco friendly, so that no harm is dealt to the planet by our existence. At the moment, we are certainly not doing anything like that and in order for us to be able to know whats right and whats wrong for the planet, we really need to open our eyes and look around. Global warming is rapidly become an increasing phenomena, the glaciers are melting at a very fast rate. Do you think this is happening on its own accord? If you do, then you need to revise your thinking. The instigators of global warming are just us. We have driven the planet to the extent that it has begun to harm itself. Every day, we use up large amounts of the resources of the planet to facilitate our lives, but do we realize who is going to replenish those resources? No, we dont. All we are intent on is making life easy for ourselves. However, the time has now come for us to make a move and change our lives so that we do not pose a threat, or become a source of harm to the planet. We need to analyze and see that whatever we are doing is according the needs of the planet or not. If it isnt, then we need to change and start green living so that the planet begins to replenish its resources and becomes the beautiful place it once was. Floods, earth quakes and all natural disasters are instigated because of us if you actually look at it in a wider sense, and all we think is that the planet is hurting us. It is not in any way trying to harm us, but these are just signs of things to come if we dont take care of our beloved planet. Many people have now begun to realize the message that is being conveyed and have begun green living so that they could be free of the guild of destroying the planet. You can start green living as well, and by following some simple guidelines, you could certainly be on your way in helping the planet. It is futile to think that one person can do nothing, but you should try and set an example for others to follow. Try being a source of inspiration to others so that they also being to adopt green living as well. Simple steps such as turning off the lights or electricity when not in use could go a long way in helping the planet, and it highly recommended that we now start to utilize our energy efficiently because it is high time that we begin to listen to the pleas of the planet and try to make life better for ourselves before things get out of hand and it all becomes too late.

Internet Censorship Two Case Studies: Australia and the United States E

I. Introduction Internet censorship laws started appearing around the world in 1995. These laws covered content already illegal in existing laws for non-internet content, as well as for content that is not suitable for minors. Worldwide, four different approaches were taken with internet censorship. 1) The government encouraged user self-regulation, and voluntary use of content filters by their citizens. 2) Laws were implemented that penalized content providers who made censored material available online. 3) Some governments instituted country wide blocking of censored material. 4) The most restrictive censorship implemented by some governments was complete blocking or restrictive access to the internet. 1 This paper will show whether the ethics of censoring internet content depends on the culture and laws of the country. I personally believe that internet censorship is not ethical and internet users should decide for themselves what they can and cannot see. This paper will prove the ethical implications of internet censorship through two case studies: the United States' Communications Decency Act, and Australia's Broadcasting Services Amendment (Online Services) Act 1999. The United States and Australia have both taken two different approaches to internet censorship. However, both countries started out with similar censorship laws. The United States in 1996 passed the Communications Decency Act. This law was later found to be unconstitutional and in violation of first amendment rights to freedom of speech. The US currently has no internet censorship laws. The Australian government uses the Broadcasting Services Amendment (Online Services) Act 1999 to censor internet traffic t o this day. II.

World Cup

Intro: GOOOOOOALLLLL!!! Many of you have probably heard this if you’ve been near or heard of soccer. Originally, I had not taken surveys for the World Cup. So by a number of hands, how many of you have heard of the World Cup? I’ll be informing you all a little more knowledge about one of the biggest competitions in the world. (Change) I’ll be teaching you all about the history of the World Cup, awards given during the competition, and about the next World Cup. (CHANGE) First, we will be discussing the history of the FIFA World Cup.FIFA stands for Federation Internationale de Football Association. * The World Cup began back in 1930 in Uruguay and only consisted of 13 teams. * Out of those 13 teams, 7 were from South America, four from Europe, and 2 North American teams. * Henry Winter states in his article that many European nations didn’t want to participate because of the length of time to Uruguay and the fear of losing their jobs. * The W. C. occurs ever y 4 years and destination changes every time. * There have been a total of 19 World Cups, the most recent in South Africa where Spain won its first W.C. * Stan Collymore states the country that has won the World Cup the most times is Brazil, by winning the W. C. 5 times and running up twice. The second nation would be Italy, by winning 4 times and running up twice. The third is Germany by winning 3 times and running up 4 times. * The U. S. has hosted the W. C. once in 1994. * Matches were held in 9 different cities * They were in Detroit, San Francisco, New York City, Orlando, Chicago, Dallas, Boston, and Washington D. C. Now that we’ve gone over some of the history, let’s talk about awards that are won. CHANGE) Second, we will be discussing awards that are won in the biggest soccer competition. * The most important and prestigious award is actually winning the World Cup trophy. * There have been two different trophies used in the World Cup, the Jules Rimet Trophy (193 0-1970) and the FIFA World Cup Trophy (1974-present). * The FIFA World Cup trophy is made of 18-carrat gold and the current holders of this trophy is Spain. * Tony Evans states that the Jules Rimet Trophy was made of gold plated sterling silver and depicted The Greek Goddess of victory, Nike.This trophy was won outright by the Brazilians for winning it three times, but was stolen in 1983 and has not been recovered (CHANGE) * . There is an awards ceremony for individual honors at the end of the World Cup Final. Each individual award is decided by a panel of FIFA heads and the winner is voted by media representatives. * The Golden Ball award is awarded to the best player in the World Cup * The Golden Boot goes to the player with the most goals throughout the tournament * The Golden Glove award goes to the best goalkeeper of the tournamentNow that we have discussed the awards given, we will finally discuss the upcoming World Cup. (CHANGE) Finally, we will be discussing the 2014 World C up that will be held next summer. * . The 2014 World Cup will be held in the nation of the most winning nation, Brazil. * This will be the 20th world cup ever. * This will be the second time Brazil has hosted the World Cup, the first time being in 1950. * There will be 12 different venues for this event. Oliver Kay mentions the average capacity of each stadium will be 54,846 people. * The World Cup final will be held in the Estadio do Maracana, which holds just over 76,000 people. In conclusion, we have discussed some of the history of the World Cup, awards given to the top players, and the upcoming World Cup next year. You will have a better knowledge and understanding of the beautiful game. Now you can share all of this with your friends and family in the summer of 2014 for the World Cup in Brazil. â€Å"

Reclusion vs. Seclusion

Reclusion vs. Seclusion Reclusion vs. Seclusion Reclusion vs. Seclusion By Maeve Maddox A reader asks to know the difference between â€Å"reclusion and seclusion, reclusive and seclusive.† Although synonyms for one another, these words are not interchangeable in every context. Of the nouns, seclusion is used more frequently than reclusion to refer to a state of being apart from society. One of its meanings is â€Å"a desirable separation from the hustle and bustle of daily life†: Wilderness lodges and resorts offer the utmost in luxurious accommodations and amenities, while providing the seclusion that many travelers seek when they visit Alaska. Shrouded by forest, Monterey estate offers seclusion, serenity In the context of public education, seclusion is a term for the prescribed separation of a disruptive student from classmates: The immediate goal of seclusion is to defuse a dangerous situation, protect the student and others from injury, and regain a safe, controlled, productive learning environment. Reclusion also refers to the state of being separated from society, but this word carries the connotation that the separation is a chosen way of life. Although the adjective seclusive may be found in the OED, it is not in common use. Reclusive is the common word used to mean, â€Å"disposed to prefer seclusion or isolation.† The word reclusion has religious origins. In the Middle Ages, women called anchoresses lived in reclusion: they inhabited a cell or small suite of rooms attached to a church and never left. Food was passed to them through a window. Some anchoresses, like Dame Julian of Norwich, received visitors for purposes of counseling, but some lived apart from all but the most necessary interaction with other people, sealed up in their cells as in a tomb. The word for a person who chooses a life of reclusion is recluse (American pronunciation: [REK-loos]; British pronunciation [ri-KLOOS]). In modern usage, the noun recluse and the adjective reclusive are used mainly in a nonreligious context. For example, well-known personalitiesliving and dead are often described as reclusive, notably, J.D. Salinger, Harper Lee, Emily Dickinson, and Howard Hughes. Here are some examples from the Web: Snowden A Recluse One Year On After Receiving Russia Asylum Reclusive  mining  heiress  leaves $30 million to the nurse For the past ten years, the London-born actor [Daniel Day-Lewis] has led a resolutely reclusive existence, locked away on a remote 50-acre estate in the mountains of County Wicklow Want to improve your English in five minutes a day?

The West Africa Regional War For observers of the West Africa regional war, the recent calm in the war-torn Mano River Union (MRU) states Liberia, Sierra Leone, and Guinea has given rise to optimism. Guarded, as this optimism might be, the decrease in violence in West Africa during the second half of 2001 is an important development given the scope and intensity of fighting that gripped these states earlier in the year. While observers agree that the current absence of widespread violent conflict in the MRU is a much-welcomed development, it must not mask the profound cleavages within these societies, the tenuous nature of the UN-imposed peace in Sierra Leone, and the continued serious threat of renewed warfare in the region. A brief overview of the horrendous and persistent conflicts that have engulfed the MRU over the past decade underscores the need for vigilance by the international community in its pursuit of lasting peace in West Africa. The past dozen years of violent conflict in West Africa have led to the death, injury, and mutilation of hundreds of thousands of people and the displacement of millions more. Conservative estimates place the total number of war-related deaths during the seven-year civil war in Liberia (1989 1996) at 150,000, more than 5 percent of Liberia's estimated population (SIPRI Yearbook, 1996). But this number only begins to tell the story of the horror that civil war brought to this small nation of 2.8 million [United Nations Development Program (UNDP), Human Development Report, 1995]. Hundreds of thousands more Liberians were injured, displaced, and terrorized by the conflict, and today the tiny state remains the hostage of its corrupt and brutal dictator, Charles Taylor. After the war spread into Sierra Leone in 1991, it had a similarly devastating effect. As in Liberia, armed insurgents preyed on the rural populations, raping, pillaging, and forcefully inducting children into their ranks. During t...
