26.02.2010 Dear Sir or Madam, I am writing to draw your attention to problems concerning threats that are connected with fishing. A study shoes that, rather than pollution, fishing appears to be the biggest threat to porpoises. Each year more than 10000 porpoises are killed in the seas around Britain. Fishingboats are using a technique witch consists in leaving the nets on the sea bed for several hours. When porpoises come to feed on the sea bed, they get caught in the nets and drown. There is a need for a research to make nets safer for porpoises. For example, one possibility would be to restrict the length of nets. This should be a duty of marine mammal organisations. Also should be limited the allowed amount of fish to be caught. This should be the duty of The Ministry of Agriculture, Fisheries and Food. Naturally it is not possible to forbid fishing
15 Many fish that live on the bottom like to be around rocks or weeds where they have places to hide and plenty to eat. Some fish hide in the rocks in the day and come out at night to eat. Find out what the bottom is like in different places by diving or looking down in the water. Find out where there are rocks, weeds or other places where fish are likely to gather. Learn the habits of the fish by setting the nets in different places to see what kind of fish you catch. It is best if the fish cannot see the nets in the water so they will not try to avoid the meshes. Set you nets when the sun is going down and haul them in the early morning so there will be no light for the fish to see by. If there are many sharks or big fish that can tear the nets, you must be careful not to leave the nets in the water too long. Sharks are attracted to fish that struggle in the nets

poverty, where individuals or families cannot afford to meet their most basic need for food. Hunger manifests itself in many ways other than starvation and famine. Most poor people who battle hunger deal with chronic undernourishment and vitamin or mineral deficiencies, which result in stunted growth, weakness and heightened susceptibility to illness. Countries in which a large portion of the population battles hunger daily are usually poor and often lack the social safety nets we enjoy, such as soup kitchens, food stamps, and job training programs. When a family that lives in a poor country cannot grow enough food or earn enough money to buy food, there is nowhere to turn for help. Facts and Figures on Hunger, Famine and Poverty In the developing world, more than 1.4 billion people currently live below the international poverty line, earning less than $1.25 per day. Among this group of poor people, many have problems obtaining adequate, nutritious food

Sustainable fishing: improving management Tuna fishing 'Almadraba' style, Spain. This type of Mediterranean fishing is based on setting out a labyrinth of nets to intercept different species of tuna in their migration. If the fishing quota is respected, this type of fishing is very selective and sustainable. © WWF-Canon / Jorge BARTOLOME Tonnara Photos in a tuna trap, and carrying Norbert's video camera.

This gear is generally used for target species tight on the bottom, such as angler, flatfish and Nephrops. By towing two nets side by side the effective swept area, and hence catch, is increased. As with the single demersal trawl above, otter boards (a) provide the horizontal spreading forces and floats and groundropes the vertical forces. The obvious difference in rigging is the third wire or central warp (b), which runs from the vessel to the clump (c), a heavy weight which can consist of short lengths of chain cable shackled together or a custom made device (Fig. 12)
Springfield by the local university physical education teacher James Naismith. He was trying to keep his gym class active on a rainy day. He sought a vigorous indoor game to keep his students occupied and at proper levels of fitness during the long New England winters. After rejecting other ideas as either too rough or poorly suited to walled-in gymnasiums, he wrote the basic rules and nailed a peach basket onto a 3,05 m elevated track. In contrast with modern basketball nets, this peach basket retained its bottom, and balls had to be retrieved manually after each "basket" or point scored. In January 1892 there was also the first official competition with nine players which ended at 1-0; the shot was made fron 7,6 m on a court just half the size of a present-day court. Basketball was spread from USA to Asia, Europe and South America. At the end of the 19th century began professional basketball. (Wikipedia 29.05.2011)

Ender loves his sister Valentine the most in this world, and his biggest fear is to become a killer like his brother Peter. Valentine The sister of Ender, she consistently comes to his defense, whether it is when Peter threatens him, or when she feels that Graff is suggesting that Ender is mentally similar to Peter. Although she agrees to go along with Peter's plan for keeping the world united by taking on the identity of Demosthenes in her writings on the nets, she believes that her ability to persuade by flattery along with her other strengths (such as equal mental abilities) will, in the end, make her stronger than Peter. She is able to use that power to keep Ender from going back to Earth, where she is sure that he would fall under Peter's control, and instead takes him to the colony, where she writes a history of the war. Peter The oldest of the Wiggin children, Peter uses threats and violence in order to control those around him

Japanese custom called hina-nagashi (?, lit. "doll floating"), in which straw hina dolls are set afloat on a boat and sent down a river to the sea, supposedly taking troubles or bad spirits with them. The Shimogamo Shrine (part of the Kamo Shrine complex in Kyoto) celebrates the Nagashibina by floating these dolls between the Takano and Kamo Rivers to pray for the safety of children. People have stopped doing this now because of fishermen catching the dolls in their nets. They now send them out to sea, and when the spectators are gone they take the boats out of the water and bring them back to the temple and burn them. The customary drink for the festival is shirozake, a sake made from fermented rice. A colored hina-arare, bite-sized crackers flavored with sugar or soy sauce depending on the region, and hishimochi, a diamond-shaped colored rice cake, are served.[3] Chirashizushi (sushi rice
teacher-topic responses. A comprehensive specification of the Intellimetric model is given in Elliot (2003). The model selects from 500 component features (i.e., proxes) (and clusters the selected elements into at least five consolidates sets. These sets include content, word variety, grammar, text complexity, and sentence variety. Other dimensions of writing may be used, but these five are common to Intellimetric models. Intellimetric uses word nets Word variety refers to word complexity or word uniqueness. The grammar composite that evaluates things like subject-verb agreement, and text complexity is similar in nature to ascertaining the reading level of the text. The information gleaned is then used by a series of independent mathematical judges, or mathematical models, to "predict" the expert human scores and then optimized to produce a final predicted score.
Although oil ingested by birds during preening may be lethal, the most common cause of death is from drowning, starvation and loss of body heat following damage to the plumage by oil. Impact of oil on fisheries and mariculture An oil spill can directly damage the boats and gear used for catching or cultivating marine species. Floating equipment and fixed traps extending above the sea surface are more likely to become contaminated by floating oil whereas submerged nets, pots, lines and bottom trawls are usually well protected, provided they are not lifted through an oily sea surface. Experience from major spills has shown that the possibility of long-term effects on wild fish stocks is remote because the normal over-production of eggs provides a reservoir to compensate for any localised losses. Cultivated stocks are more at risk from an oil spill: natural avoidance mechanisms may

Il est confirmé que des logiciels de sous-titrage différents cal- culent des valeurs de vitesse de lecture différentes (tant en CPS qu'en MPM) pour le même en- semble de sous-titres. C'est pourquoi nous présentons une application informatique très simple pour le calcul des valeurs de CPS et de MPM. Elle a été volontairement conçue pour ne pas émettre d'hypothèses, mais pour simplement compter les caractères et effectuer des calculs nets et précis du temps d'entrée et de sortie des sous-titres. Le nouvel outil permet la recherche em- pirique et quantitative de grandes séries de sous-titres simultanément, et il pourrait aussi jouer un rôle important dans l'environnement de la classe.

Later, a suite would be arranged from this music.3 It is picturesque and Põldmäe is in his beloved “element”, the score being rich in colours. The music is well suited to the fantastic plot. The timeless action takes place on a nameless island. The ruler Kaspar is an unrestrained despot celebrating his upcoming wedding. The islanders go to the seashore to fish with a seine in order to pay homage to the bride. They are astonished to find a Mermaid in their nets trying in vain to escape back to sea. Kaspar announces that he will spend his wedding night with the Mermaid after the feast. This does not happen because the Mermaid has fled. An example of the use of colour from the beginning of the ballet suite; it is a sound canvas, the flow of time, a lonely island and stillness: 1 First performance by ERSO, 21 June 1970, conducted by Roman Matsov. 2 Taken from the short fantasy story by Friedebert Tuglas. 3

Fleet. A few hours earlier, a message had arrived from Tokyo that caused Commander Mitsuo Fuchida, the pilot who was to head the first wave of the air attack, to breathe a sigh of relief. It had been relayed from Yoshikawa, and it reported that no barrage balloons had yet been emplaced to protect the fleet from air attack. The same message also caused Commander Minoru Genda to sigh with relief. It stated that the battleships appeared not to be protected by torpedo nets. Genda had conceived the plan of shallow-water torpedo attack on the anchored American ships. A little more than an hour after the hands of Honolulu clocks had snipped off December 6 and opened out into the first hours of December 7, the Pearl Harbor strike force received Tokyo's relay of Yoshikawa's final message. The American ships were still in harbor, awaiting the ax stroke with fat complacency. They were apparently not even protected by air search. Was it all a decoy
