How to Calculate Gross Tonnage of a Ship

How to Calculate Gross Tonnage of a Ship The term gross tonnage refers to the internal volume of a water-going vessel, and is normally used as a means for categorizing commercial vessels, especially those used for shipping. This volume measured includes all areas of the ship, from keel to funnel and from bow to stern. In modern usage, the measurement deducts the crew spaces and other parts of the ship that cannot hold cargo. Since 1969, gross tonnage has been the principal means by which a  commercial ship is defined. The gross tonnage measurement has a number of legal and administrative uses. It is used to determine regulations, safety rules, registration fees, and port charges for the vessel.   Calculating Gross Tonnage Calculating the gross tonnage of a ship is a somewhat complicated procedure, due to the fact that most ships have an asymmetrical shape that makes calculating volume difficult. There are many ways to make this calculation, depending on the level of precision required and the agency requiring the measurement. Different formulas are used depending on the shape of the vessel, and even the types of waters on which the ship sails. A simplified set of gross tonnage formulas is set forth by the U.S. Coast Guard Marine Safety Center, which are based on three measurements: Length (L), breadth (D), and depth (D). Under this system, the means of estimating gross tonnage is as follows:   For a boat with a simple sailing hull, gross tonnage (GT) (.5 * L * B * D) / 100For a sailing boat with keel, GT   (.375 * L * B * D) / 100For freighters with angled or cylindrical hulls, GT   (.67 * L * B * D) / 100For ships with square barge-shaped hulls, GT   (.84 * L * B * D) / 100 The  International Convention on Tonnage Measurement of Ships  sets forth another, more precise formula for calculating gross tonnage of a vessel, which says GT   K  *  V. Here, K .2 .02 * log10(V), and V interior volume of a vessel in cubic meters (m3). History of Gross Tonnage as a Measurement Standard Since most commercial ships were originally involved with the transport of goods, otherwise known as cartage,  ships at first were rated and valued on the maximum amount of cargo that could be stuffed into every nook inside a ship. On long sailing voyages, after selling their loads of cookware, tools, machinery and other products, private traders often bought bundles of lumber, spices, cloth, and decorative goods to sell upon return to home port. Every space was stuffed full to maximize profit on both legs of the voyage, and thus each boats value depended on just how much open space was available in the vessel. One of the few exempt spaces in these early calculations of a ships volume was the bilge area, where ballast was held. In early shops, no cargo could be stored here without damage since in these wooden ships the bilges were wet. Ballast stones were used on sailing ships that were leaving with a light load and returning with a heavy cargo. This might be the case when transporting a finished metal such as copper to a port where raw copper ore was loaded for the trip back to England for refining. As the lighter load was unloaded and the heavier load brought aboard, the bilge stones were removed to compensate for the extra weight. Today, piles of these foreign stones, roughly the size of bowling balls, can be found underwater near historic ports all over the world. Eventually, with the availability of mechanical pumps,  water as ballast  became the norm,  since it was much more efficient to simply pump water in and out of the bilge to adjust the ships weight rather than use stones or other forms of weight.   Ã‚   The term  tonnage originally  came into usage as a means for referring to the physical space occupied by 100 cubic feet of ballast  water, an amount of water that was the equivalent of about 2.8 tons. This can be confusing since a ton is usually thought of as a measurement of weight, not volume. In the context of maritime shipping, however, the term tonnage refers to the volume of space available to hold cargo.

Beta Blocker Treatment in Heart Failure Literature review - 1

Beta Blocker Treatment in Heart Failure - Literature review Example Studies confirm that Carvedilol therapy is more superior to the latter two Beta Blockers compared. This is due to its nature characteristics that entail possessing Alpha1 Beta1 and Beta2 whereas the two have only Beta1-selective receptors. Besides Carvedilol has vasolidilating characteristics, which is not evident in other Beta Blockers. However, not all people having Systolic malfunction qualify for Beta Blocker therapy. Since, it necessitates that one be in a stable condition and non-hospitalized. Random admission of the therapy on patients with absence of meticulous scrutiny normally results to patients’ death or complex predicaments, besides physical deterioration of the body. Admission of Beta therapy encompasses starting with small and regulated dosage until the patient attains the tolerable state for large doses. This therapy also sternly shuns attempts meant for abrupt discontinuation of the dosage because of its grievous effects. Since it yields to circulatory deterioration characterized by electrophysiologic unsteadiness. Finally, it has various side effects that if not attended to effectively may yield to be ruinous to the patients. For instance, some comprise Bradycardia, Fatigue, lightheadedness and frequent headaches, Insomnia, Chronic chest aches, High triglycerides and depression. Beta Blocker besides its present efficacy as a remedy for heart malfunction, it requires further study to reduce both the evident and future derivatives. This will ensure ailing persons do not suffer other complications while trying to cope with the main grievous predicament (chronic heart failure).

Pain Sounds Aesthetically Essay Example | Topics and Well Written Essays - 1250 words - 1

Pain Sounds Aesthetically - Essay Example The Ballade starts with what sounds like several first clumsy words of a speaker. The speech’s resolute, yet there’s no audience to listen. This feeling of solitude firstly comes from a chordophone only sound: that single speaker is a piano. Secondly, those first â€Å"words† are conveyed by a low pitch. They sound full and resolute due to the loudness of dynamic and long dramatic intervals. Along with overtones that imitate echo, a feeling of no audience’s achieved. Then, phrase by phrase, â€Å"a speech† becomes more normal, logical as dynamic becomes softer, there’re already shorter intervals, and feeling of description comes from a developing accompaniment (basically, chords). Yet a general nervousness stays in this section as well as during the whole Ballade. To oppose the first melody, Chopin starts a new one in a second section (3:18) with the higher pitch (â€Å"Zimerman plays Chopin Ballade No. 1†). The second melody’s dreamy, and it’s developing brings a feeling like a compositor’s dreaming or remembering some nice times. Sound becomes generally, more relaxing due to softness in dynamic; more water-like or misty due to vanishing intervals. It seems that the composer gives listeners an opportunity to have some rest until the dynamic part begins. There’s a minimum of attacks, maximum of decays when performing the second section, but not for long. The first melody returns in the third section (4:20) bringing a feeling of screaming or at least, a loud dramatic, maybe accusing, monolog again. This feeling comes from dominant dynamic loudness, from intervals between accompaniment and the melody, and dominant attacking style of performance, until suddenly, Chopin gets lost in own images, and feelings in forth section (5:23). The feeling of a noisy mess’s achieved by a higher pitch and that now they're more sounds for each time with dominantly, a stable loudness and no interva ls.

Post-modern management Essay Example for Free

Post-modern management Essay It has always been the goal of man to be able to describe humanity and the world in which they live in. In doing this, we are inclined to search for answers, to find resolutions to our needs and problems. Decisions become important and the ability to use knowledge to make intelligent choices become essential. It is not such a wonder then that through all those years, man has developed countless theories and practices and had reinforced them with countless examples. In the world of management and leadership, the conventional approach to things involves a rigid and tested way of creating solutions. Traditional management science, furthermore, involves the use of computational processes to organizational decision making. It starts off with the recognition and definition of the problem in the real world. The ultimate goal then is to find what is needed is to be able to bridge what the present situation lacks to what the intended result is. It is a beginning of the search for improvement. Conventional methods use an idealized and linear manner to fuse the problem and a known pattern or puzzle to create a solvable model. To make a good intellectual decision, it is necessary to conduct optimization, forecasting, modeling and simulation, and decision analysis. It involves finding out what the best feasible option is, what it entails for the future and what its result would be for varying situations. Models are used wherein the object is to be able to match a puzzle to represent the problem in the real world. Traditional models such as linear and dynamic programming, queuing, discrete-event simulation and causal models are used and from all of these, ultimately the best decision is made. This discipline has become integrated to the basic field of management and has become a standard for various functions of business. (Whalen, 2001) In the context of marketing, traditional methods of simplification and reduction to formulae are used. Highly structured devices, pre-determined market and brand standards are employed to achieve desirable goals. Marketers are the one controlling and driving these goals and therefore consumers respond to this. (McKernon) Robbins, in the article of Summers et al. , further reinforces these patterns of cause and effect by relating organizational behavior through scientific methods. The real world is â€Å"mirrored† by organizational behavior through methods of investigating behavior†. (Summers, 1997) Robbins argues that most of the generalizations of man are made on the basis of intuition, not proven facts and thus investigation is needed. Intuition is likened to common sense and that, most of the times, it is inaccurate. Robbins further explains that common sense is different for different groups of people and that investigation tackles diversity. By investigating, managers can better and more precisely handle and predict the behavior of their personnel. This investigation must be coupled with good research especially on the comparison and weighing trade-offs. The use of case studies, surveys, and experiments must be implemented. Robbins further reiterates that generalizations and conclusions must be based on systematic study, scientific evidence supported by verified data. Organizational behavior knowledge is attained by avoiding intuitive approach and focusing more on knowledge based on meta-quantification analysis and surveys. (Summers, 1997) The leader or manager eventually uses these techniques to properly guide the organization and his/her employees. Optimal leadership ultimately depends on internal and external factors. In the organizational behavior perspective, leaders use contingencies such as national culture, gender and race to improve and strengthen the relationship with subordinates. This contingency theory theoretically provides the manager with the capability to independently make decisions and to do amendments necessary to obtain the desired result. Summers et al. , argue that this is a one-sided view. The conventional organizational behavior methods only show how managers can exercise their influence on the workers but not the other way around. Traditional ways involve exploitation and discipline and encourages an ideology of domination. â€Å"Managers are taught skills in getting workers to accept the status quo, to get ahead and to get along with others but not to question the game plan†. (Summers, 1997) As evident in the deconstruction of Robbins article, Summers et al. propose a de-emphasis on this rigid structure of conventional management. Whalen et al advocate this postmodern view and puts focus on discourses and de-emphasized precise and fixed meanings. With this premise, the dynamic quality in knowledge is established. Soft computing is rallied to be a faster, more creative approach to solutions although admittedly, it welcomes inaccuracy and ambiguity. In the perspective of knowledge management, however, this postmodern approach provides ways for problem management that cannot be quantified through mathematical computations. Whalen et al. further discuss three types of knowledge approach, creation by means of evolutionary and neurocomputing, deployment through decision support systems, and discovery by data mining, applied virtual reality and data visualization. In neural methods, the model build on gathered data and experimentation and proceeds by the random systematic search. The model is based on a fixed database and relies on the matching that of an existent criterion. With experimentation, on the other hand, the aim is to look for an action from a set of choices and parameters that would result to the desired outcome. Decision support systems may also use the case-based approach. Knowledge is derived from various case studies and banks on experiential logic to create the optimal response to a problem. Moreover, data mining utilizes different techniques to look for patterns that associate and correlate various fields of databases. Data visualization and virtual reality applications likewise bring the important contribution of human perception that is irreplaceable by artificial computer simulations. Whalen et al. stress the importance of humanizing the decision process and that the organization’s stakeholders are best catered to when managers are able to produce the right choices that assert the organization’s goals and mission. As the world is getting more complex and dynamic, a postmodern stance must be advocated and that this will â€Å"greatly advance our ability to understand how humans make perception based rational decisions in an environment of imprecision, uncertainty and partial truth† (Whalen, 2001) The postmodernism approach also applies to consumer marketing. The media and marketing are important to aid the people in knowing and explaining the things around them and the events that are occurring. While the consumers are getting smarter, a need for a more suited method arises. In postmodern marketing, the styles of consuming and strategies of the consumer are given more emphasis and focus. In an environment that is mobile and complex, sustainable dynamic techniques must be employed. This approach challenges diversity and creates avenues for discourse among differing people. This is beneficial to managers, employees, consumers, and stakeholders alike. With the right facilitation of information, a brand can reach more of its market and thus generate more favorable returns. Postmodernist approach also banks on the use of critique and story-telling for consumers. Effective stories would be able to connect to the consumer and that its result relies on its ability to provide the consumers with meaning and explanations. Critique, on the other hand, is essential for a brand in that it generates feedback; whether it was a success or not depends on the informed reactions of the users. Reinvention and smooth changing of styles are important techniques in a rapidly changing world. A careful way of guiding the consumers from the familiar and traditional to the contemporary and new must be done with good aptitude. McKernon) It is a fact that the world has increasingly become more complex and ever-changing. At the very least, the knowledge that we have to gain and understand about life in general is much more vast and challenging and that traditional methods and techniques for problem solving, whether in organizational behavior or marketing might actually be lacking in such that they may not be able to solve and explain the entirety of the world’ s troubles and unquantifiable conceptions. It is therefore imperative that a healthy mix of traditional and postmodernist approach to business and management be utilized to be able to grasp more of what the world is telling us. Leaders, employees, customers and stakeholders alike must be able to make informed decisions and take into consideration the various models, theories and practices both old and new for them to make real and objective sense of the world and its organization.

Henry VII & Richard III :: European Europe History

Henry VII & Richard III Richard the Third had just recently become King of England. But he did not know that soon he would not Henry Tudor was from Wales. His surname was really spelt 'Tewdwr.' It was changed to the English way though when he became King of England. Henry was too to France by his Uncle Jasper in 1471, fourteen years before the Battle of Bosworth. His uncle took him to Brittany. There, Henry learnt a lot. He learnt about warfare, treachery and betrayal. He also learned about court politics and how to keep supporters. This helped Henry very much with the Battle of Bosworth. Henry landed at Milford haven in South Wales. He had about two thousand soldiers with him. He marched all through Wales and the Midlands. When he got to the battle site he had around five thousand troops. He had gained more than three thousand on his journey. The battle was fought up on a hill at Bosworth. At the battle site there was a third army. It was small and led by Lord William Stanley. It did not know what side to join. Henry started the battle by moving up the hill and charging at Richard. Stanley decided which side to join. It would be Henry's. He hit on the rear of Richards army causing the Kings forces to run. Richard fell from his horse in the rush and was eventually killed. As the battle ended, Stanley found the Kings crown hanging on a thorn bush. Lord Stanley crowned Henry the King of England. Henry then married Edward the IV'S daughter Elizabeth. This united both of the families together. The battle of Bosworth wasn't any old battle. It was very important in history. The Lancastrian, Henry Tudor defeated the Yorkist, Richard the third at the battle of Bosworth field in 1485 and became King

Commentary: An Advancement of Learning by Seamus Heaney Essay

In An Advancement from Learning by Seamus Heaney, he describes a retrospective childhood experience. The narrator compels himself to face a deep-seated and preposterous fear which he consequently conquers. He shares his terror and revulsion by implementing vivid and vibrant imagery presented in nine quatrains. The conquest of an irrational fear depicted in this poem is perhaps a metaphor for overcoming greater fears in life. As the title suggest, this poem is about An Advancement of Learning- facing and subsequently conquering sometimes strong and private fears. Heaney describes a lone stroll along a polluted, ‘oil-skinned’ river bank. The almost sombre introspective tone of the opening two stanzas rapidly changes into one of revolt and terror as a rat emerges from the river. In a moment of panic, the poet attempts to escape, only to find another on the far bank, which encouraged a deeper impact. The second rat provoked the author to question his response to and fear for these animals. He then ‘incredibly’ decides to courageously maintain his ground and face the rodent. Despite Heaney providing the reader with a vibrant image of the animal to reinforce his contempt, he almost battles the rat until he ‘stared him out’. Eventually, as if the narrator won the ongoing battle, the rat retreats into a sewage pipe. Heaney then advances his way and triumphantly crosses the bridge, as he conquered a fright which has bedevilled him since childhood. An Advancement of Learning is written in nine quatrains consisting of short and sharp lines, which almost present the reader with a succession of flashing images. Heaney employs a loose and alternate rhyming scheme- stanzas one, three, six, eight and nine follow the pattern abcb, whereas stanzas two and four follow the abac pattern. Where the seventh stanza follows the abab pattern, Stanza five has the different but effective rhyming scheme abbc. The regularity of the rhythm in this stanza contributes to the reader’s sense of the poet’s rising self control. Heaney makes active use of enjambment and caesura to emphasise many of his emotions and sentiments. The astute use of enjambment from lines ten to sixteen increase the tempo and excitement of the poem, which in turn aid to convey the poet’s  fright and aspiration to flee. Furthermore, the writer applies enjambment between one stanza and the next to allow his descriptions to flow smoothly, which appropriately reflects the fluidity of the river described. Interesting is that the verses reflect the writer’s gradual gaining of self control. The main entity in the poem is the bridge as it symbolises the tree stages in the writer’s conquest of fear. At the sight of the first rat, the poet initially refuses to cross the bridge. Once faced with his ‘enemy’, he establishes a ‘dreaded Bridgehead’ which in military terms means to hold a defensive position. He is fearful but determined. Finally, as the poet defeats his foe and fear, he, with a vestige of triumph, ‘walked on and crossed the bridge.’ The bridge is mentioned at these three key stages of Heaney’s experience as well as structurally in the first, central and closing stanzas to emphasise the stages of overcoming his fear gradually. Heaney’s most striking feature in terms of style and language are unmistakably his effective use of alliteration and sibilance, as well as the appealing use of lexis. The repetition of the sharp consonant sounds s and c, especially conspicuous in the third stanza, contribute to both the sickening nature of the rat and the writer’s feelings towards it. An example of words carefully chosen to enhance and reflect the meaning of the poem is ‘Insidiously listening’, which is despite its impact, neither alliteration nor assonance. The narrator also employs extraordinary and emotive vocabulary, such as ‘slimed’ and ‘nimbling’ to describe the rats, allowing the reader to accurately experience the fear and loathing which he suffered. Remarkable about this poem is that as the writer overcomes his revolt and fright, the description of the animal becomes more forgiving. Where at the beginning the rodents were Insidious, ‘slobberedâ€℠¢ and ‘slimed’ around, they are, less forbiddingly, observed as animals with ‘the raindrop eye’ and ‘the old snout’ towards the end. This indicates how the writer’s fear and terror disappears with the rat into the sewage pipe, and how he now views the rodent in its proper perspective. An Advancement of Learning successfully conveyed the writer’s feelings and  emotions while conquering a lifelong phobia. The use of enjambment and caesura as well as the alternating rhyming patterns, which reflected the increasing order of the situation, all contribute to the vibrant image the reader is provided with. Furthermore, the poet employed the motif of the bridge as a foundation for the poem’s structure while adding more dimension to the text by enforcing it as a symbol of the poet’s route to overcoming his deep-rooted fears.
