Ship ballast water management is recognized one of the huge problem of international maritime society. To take and charge some harmful micro aquatic organisms and pathogens with in ballast water, these are delivered to some sea area in the world by ships and discharged. This was serious phenomenon on marine environment not only maritime society but also human society. International Maritime Organization (IMO) was adopted the new convention, International convention for the Control and Management

Introduction The human foot and ankle are composed of 26 bones, 33 joints, and more than a hundred muscles, tendons and ligaments. These components work together to provide the body with support, balance and mobility. The foot acts as a “rigid lever and mobile adapter” (Amstrong [Prosthetic feet], 2010). The human foot must be capable of withstanding the body’s weight and functions as a shock absorber (Swierzewski, 2007; NYU, 1990). The prosthetic foot needs to be capable of mimicking the missing
and heeling the water creates resistance on the keel to counteract the sideways force of the wind and result in a forward movement (Wolfe). But how can a smaller keel counteract the force on a much larger sail? Well the density of water is 1000 kg/m^3 and the density of air is 1.2 kg/m^3, so water is approximately 833 times denser then air. This means that more force is being exerted per square meter on the keel than the sail, so even though the keel is smaller it is still applying enough sideways
McDonaldization About seven months ago, I met an American guy who had arrived at New Zealand just a few days before. While exchanging our sentiments (I am from Japan) on New Zealand and its culture, the guy told me how he was surprised to see the country is so Americanised, mentioning McDonald’s as one of the examples. Now, in a different sense, this was surprising to me, too. I had never had the idea that having McDonald’s is being Americanised. In fact, McDonald’s is nearly everywhere in the world
sail boat for most beginners to understand is the keel or centerboard. The keel of the boat does many things, it acts as a pivital point for sharp turns and "jibbing", it helps keep the boat upright by lowering the center of gravity of the boat, it works to keep the boat moving in a line of motion close to that of the direction that the boat is facing. This is because the boat is usually being pushed heavily to the side by the wind. And the keel also works to pull the boat into the direction of the
Introduction The word “commodity” is a term that means “an economic good” (Britannica, 2012) which can be either a product or a service that can be traded or exchanged. Commodities vary in their type, value, benefits, and quality. Of the numerous average commodities that exist throughout the globe, commodities holding greater values also have their own ranking as being precious commodities. Such precious commodities include gold, a precious metal that had been highly valued since ancient times and
As service went on, I could see old man Johnson staring at some of the boys I saw last night that were trying to stomp out the fire. When Reverend Keel said the final blessing, he asked for the ones that follow God to pray for the wicked children who caused old man Johnson's barn to burn down. In the corner of my eye, I saw my mother turn her head and glare at me. The church was dismissed, and while
Anorexia nervosa and Bulimia nervosa are described as psychological eating disorders (Keel and Levitt, 1). They are both characterized by an over evaluation of weight. Despite being primarily eating disorders, the manifestations of bulimia and anorexia are different. They both present a very conspicuous example of dangerous psychological disorders, as according to the South Carolina Department of Health, “Eating disorders have the highest mortality rate of any mental illness” (Eating Order Statistics
Pagiophyllum. The two genera closely resemble one another in foliar morphology. However, combined transmitted light and polarizing microscopic observations together revealed additional characters such as the pattern of leaf arrangement, cushions and keel size, shape of leaf apices and bases. Since cuticular are not preserved, specimens are assigned to their genus level only. Both specimens have leafy axes with imbricate, spirally arranged scale like leaves. This indicates their affinity to family
As You Like It - Rosalind and Celia A search for feminist criticism on William Shakespeare's comedy, As You Like It, uncovers a range of different aspects of the play and its players, but none is as well represented as the nature and dynamics of the relationship between Rosalind and Celia. Among other topics are cross dressing or female transvestism and male self-fashioning, which extrapolates on the mode of dress being an identity. A feminist view on Shakespeare examines the poet's defense
1.1 Gait Basics Walking is essentially a cyclic activity, with both the legs undergoing the same motion, but with the cycle timings displaced. If it is assumed that the body is symmetric, describing one cycle for a single leg is sucient. It is important to consider the fact that every human being has a di erent gait and what is considered a normal gait for that person will depend upon his age, sex and body geometry among other factors. The moment the foot makes contact with the ground is generally
to build. Smaller versions of these boats are called Jon boats. The bigger styles of the Jon boats are barges. The second type of vessel bottom is a round with keel design. The keel design is a narrow V-shaped hull that extends underneath to create a centerline to keep it from rolling over in rough waters. A few problems with the rounded keel hull are that it cannot travel in shallow waters. This type of boat is also more expensive to build than a flat-bottom Jon boat. The last type of boat hull is
The Fate of the Vasa a) Things that went right: 1. The ship was completed in the designated timeframe with gaudy decorations. 2. Almost everything was as per the plan, apart from the fact that the base was destabilized. Even after frequent transformations, the ship was designed according to what the King wished for. b) Things that went wrong: 1. Henrik Hybertsson (the shipwright) became ill and died in 1627 He died one year before the Vasa was completed. During the year of his illness, he shared
As surprising as it may seem, one of the most common household items, cardboard, can be used to construct a boat. Building a cardboard boat has become a fun activity that anyone can take part in. Towns and schools hold annual cardboard boat regattas, judging the entrants on speed, design, and creativity. In New Richmond, Ohio there is even a cardboard boat museum! These special boats are more than just a box thrown into water; they are designed using elements of engineering and physics to make
Oh Captain In the poem “Oh Captain, my captain” was written by Walt Whitman. This poem was written in 1865 during the civil war and President Lincoln. Whitman admired Lincoln and would gave aid to the wounded soldiers. The writer is referring the war to a ship and is using nautical terms to describe the death of the president. Walt Whitman wrote four poems on the death of Abraham Lincoln. One of the four was “Oh captain, my captain” (Vendler 2). This poem is formally rhymed poem. In the first

There is no coincidence that the rise of Athenian Democracy goes chronologically hand in hand with the rise of the Athenian Navy. Following the defeat of the Persians by the Greeks, Athens’ naval successes allow it to surpass the previous naval power of Corinth; create the Delian league to fund and support this navy; and eventually ruffle enough feathers with their fellow Hellenic neighbours that they inspire the Peloponnesian war. Overall their naval reputation and intimidation comes from the skill
Sailing has been around for millennia, and is considered to be one of the earliest and most environmentally friendly methods of water transport. Sailboats act as a method of transportation, exercise, and entertainment. These now more structurally developed and masterfully modeled ships have been engineered for efficiency, and these advancements have ensured durability and speed among modern sailboats. The great strength and ability of sailboats has given competitive owners the opportunity to participate
