All of organisms need oxygen no exception organisms that live in the water. Aquatic life like fish, get the oxygen in the form of dissolved oxygen. In the absence of dissolved oxygen at certain levels many kinds of aquatic organisms will not survive in the water. Many aquatic organisms can not survive even be dead in an already polluted waters is not caused by contaminants toxicity directly, but can occur due to lack of oxygen because oxygen is used in the process of destruction of contaminants, both biological and chemical reactions. Bay of Manado is the waters that interact with the activities on the mainland, where all the waste from the mainland, both originating from urban settlements as well as those sourced from the industrial area of trade, restaurants and hotels will go into drainage channels and brought to shore. Waste in coastal waters and marine ecosystems will dissolve in water, there is a sink to the bottom and are concentrated into sediment. Waste materials in the aquatic environment will decompose through oxidation reactions, in which oxygen is required in this process. Oxygen demand in the waters, to determine how far the level of environmental pollution has occurred, one way to be taken for that purpose is to do a Test Chemical oxygen demand (COD).…...

French Village

...new province. Many of them settled on the ruins of abandoned Acadian villages where many Acadians had settled their families. After the destruction of the “Pointe-Saint-Anne” village in the winter of 1759 by Lieutenant Moses Hazen and a group of rangers, where he was only able to capture three of its families, many of the Acadians were able to flee the village. Some of these Acadians fled west and settled near the Malecite village of Ekoupahag. Afterwards, many other Acadians started to settle nearby, and some settled at what became French Village. One of the pioneers of the French Village was Jacques Daniel Godin who was the grandchild of Gabriel Godin who was one of the founders of the Acadian village of “Pointe-Saint-Anne”.1 The French Village was situated about seventeen kilometres from what became the City of Fredericton, and is now part of Kingsclear.2 There are stills ruins of what seems to be an old church that burned to the ground, and also an old cemetery where we can find Acadian tombstones mixed with those of the Loyalists’.3 1.

Little Village

...Introduction South Lawndale (Little Village) is located on the west side of the city of Chicago, lllinois, Is one of the 77 well defined Chicago community areas. History After the great Chicago fire of October 1871, many residents of Chicago were looking to move away from the crowded city. Areas on the city’s outskirts were quickly being developed, even as the ashes and rubble from the great fire were still being cleared. In 1871, Chicago real estate investors wanted to build an affluent subdivision in the suburban area west of Chicago, choosing an area just short of the Chicago city limits. The original subdivision was bound by Twenty-second Street, Twenty-sixty Street, Hamlin Avenue and Homan Avenue. Investors decided to built all homes to be constructed of brick, ranging from $2,500 to $8,500. ( Chicago Littles Village) By the turn of the 20th century, the west side of Chicago would become the largest industrial section of the city, and as a result, the more affluent residents began to move away from the Little Village area. They would eventually be replaced by immigrants, mostly of Eastern European extraction, from Czech Republican, Poland, Germany, and Hungary. Fast forwarding to the early 1960’s, Little Village began showing some troubling signs of change. Many of the community’s residents were moving farther west to the Czech-dominated suburbs of Cicero and Berwyn. This was largely due to fear based on the rapid changes just north of Little Village......

Alpine Village Case Study

...Financial Forecasting: Riverview Community Hospital Alpine Village Clinic is a small walk-in clinic located next to the primary ski area of Alpine Village, a winter resort close to Aspen, Colorado. The clinic specializes in treating injuries sustained while skiing. It is owned and operated by two physicians: James Peterson, an orthopedist, and Amanda Cook, an internist (Gapenski and Pink, 2009). The clinic has an outside accountant who takes care of payroll matters, but Dr. Cook does all the other financial work for the clinic. However, to help in that task, the clinic recently hired a part-time MBA student, Doug Washington. First Bank of Aspen is the primary lender of Alpine Village and due to a forecasted reduction in bank deposits, First Bank has asked each of its commercial loan customers for an estimate of its borrowing requirements for the first half of 2010 (Gapenski and Pink, 2009). Dr. Cook asked Doug to come up with an estimate of the clinic’s line-of-credit requirements to submit at the meeting. A line of credit is a short-term loan agreement by which a bank agrees to lend a business some specified maximum amount. The business can borrow against the credit line at any time it is in force, which typically is no longer than one year. When a line expires, it will have to be renegotiated if it is still needed. The amount borrowed on the line, or some lesser amount, can be repaid at any time, but any amount outstanding must be repaid at expiration (Gapenski and Pink,......

Village of Cannibals

...Throughout history there has always been social gaps. These are seen by rural and urban populations, and the upper and lower classes. In France in the nineteenth century, this was prevalent throughout the country’s provinces. The people spoke different dialects of French and they did not really identify together as a whole. The people were separated by both class and location through oppression and progress. Hautefaye was a small village in France that was filled with agrarian peasants. It also had some aristocrats who mingled amongst the population without worry. This was controversial because the urban bourgeoisie did not socialize with the urban poor. The nobility that lived in Hautefaye had owned their property for generations. The rural village, like most villages in France, liked to host fairs where the peasants gathered in economic and social activity. The fairs were supervised by government supplied gendarmes. Fairs were known for their violence. Men took part in fairs and they drank alcohol, which was the main festive beverage. For this reason, the alcohol sometimes got the best of the men and fights were common throughout the fairgrounds. Young boys got to follow their fathers around and learn the ways of a man. The economic activity that went on at fairs was stimulating to the community and helpful to those who took part. Propaganda became a key source in swaying the masses. The bourgeoisie used it to portray the nobility as bad and arrogant. Our textbook......

The China Cancer Villages

...The China Cancer Villages Shuiman Di Introduction In the modern world, cancer has become a common ailment and cause of death for millions of people worldwide, but it is frightening when human settlements are identified with the disease due to the high magnitude at which it strikes the populations. Cancer villages may appear like any other human settlements and people go on with their daily lives as if life was just in its normal state. However, upon scrutiny, these villages have striking characteristics that lead towards the indication that life in these areas may not be normal. In some of these villages, the water from rivers and wells is polluted to the extent that people have to rely on bottled drinking water. In others, some sections that are close to major sources of pollution have been vacated, while other areas are no longer agriculturally productive. In some of these villages, the villagers have turned to dumping garbage into ponds or rivers that are considered ruined by pollution. The level of pollution around the cancer villages has been so rampant that crops die off, fish, shrimp and other water creatures vanish from the rivers, animals become infertile or deformed and children suffer extensively from respiratory diseases. Most of China’s cancer villages have been turned into death pots by the effects of industrial pollution that have increased since 1990s. Therefore, the emergence of China’s cancer villages can be attributed to the rampant......

Hilts, Smokescreen 185 (1996)) I. Introduction Tobacco has been an agricultural staple from the time of the first recorded European encounter with the plant in the fifteenth century.2 The pervasive nature of its cultivation and consumption has made tobacco one of the most profitable crops in world agricultural history.3 World production is estimated at thirteen billion pounds annually, originating in more than one hundred countries.4 This production has flourished, in part, due to the demand for cigarettes, the leading form of tobacco consumed in the global marketplace. The World Health Organization (WHO) has estimated that 1.2 billion people over the age of fifteen are regular cigarette smokers.5 In developed countries, 35 percent of men and 22 percent of women smoke cigarettes on a regular basis.6 In developing countries, 50 percent of men and 9 percent of women smoke cigarettes on a regular basis.7 Globally, smokers consume 5.5 trillion cigarettes every year, which translates into a consumption rate of one......

Salem Village

...In Salem Village in 1692, Betty Parris, age 9, and her cousin Abigail Williams, age 11, the daughter and niece (respectively) of the Reverend Samuel Parris, began to have fits described as "beyond the power of Epileptic Fits or natural disease to effect" by John Hale, minister in nearby Beverly.[13] The girls screamed, threw things about the room, uttered strange sounds, crawled under furniture, and contorted themselves into peculiar positions, according to the eyewitness account of Rev. Deodat Lawson, a former minister in the town. The girls complained of being pinched and pricked with pins. A doctor, historically assumed to be William Griggs, could find no physical evidence of any ailment. Other young women in the village began to exhibit similar behaviors. When Lawson preached in the Salem Village meetinghouse, he was interrupted several times by outbursts of the afflicted.[14] The first three people accused and arrested for allegedly afflicting Betty Parris, Abigail Williams, 12-year-old Ann Putnam, Jr., and Elizabeth Hubbard were Sarah Good, Sarah Osborne, and Tituba.[15] Sarah Good was homeless and known to beg for food or shelter from neighbors. Sarah Osborne had sex with her indentured servant and rarely attended church meetings. Tituba, as a slave of a different ethnicity than the Puritans, was an obvious target for accusations. All of these outcast women fit the description of the "usual suspects" for witchcraft accusations, and no one stood up for them. These......

Village Volvo`s service package would include: Supporting facility: Butler Building with four work bays, an office and waiting area Facilitating goods: Replacement auto parts Information: CCVD, test drives, diagnostics, vehicle problem discussion Explicit services: Smooth – running automobile after performed services Implicit services: Worry –free auto repair, safety. 2. Village Volvo provides comfortable atmosphere for its customers (well equipped waiting room), complimentary additional services such as vacuuming which increase value of services received. They have also split their services between routine maintenance and general repairs in order to meet the time requirements of their customers. They will only bill what they estimate without the customer’s prior approval and they return all worn parts so the customer knows the services were performed. 3. Village Volvo currently operates in a business to consumer (B2C) environment where the customer is considered and is active in the entire service process. If Village Volvo was to run its repair operations more like a factory (which I don’t suggest), the consumer would just fill out a form as to what was wrong with the vehicle and Village Volvo would fix the problem and deliver the repaired car. Under this format they would be able to actually work on cars for a greater part of the day as they would no longer need to spend time interacting with the customer. Village Volvo would......

The Village

...The Village Movie synopsis Peoples’ perceptions can change how we ourselves view the world and what’s going on in it. Making sure we understand perception vs reality will help us think critically and see things both subjectively and objectively. Covington is a 19th century town in the middle of the woods comprised of town elders, chiefly Edward Walker, and their families. In the woods that surround the town, there live creatures who are not named and with whom the townsfolk have had dealings in the past, while not shown; a deal of a sort has been worked out between the creatures and the village with the understanding that the villagers will not venture past the safe points and the creatures will not breach these points from their side either. A young man of the town dies of an as yet unknown disease that a few members think may have been treatable if he just had the medicine. Lucius Hunt appeals to the village elders to let him travel beyond their safe border to the towns past in order to get medicine to ensure this does not happen again, and possibly to heal the mental illness of Noah. Lucius is quickly denied the request. Lucius is approached by Kitty in hopes that they will marry, but Lucius is in love with Kitty’s sister Ivy, who is blind, but can “see” auras around certain people. Noah is in love with Ivy and presents her with berries of “the bad colour” (red, which is not allowed in the town, as it’s feared to bring out the monsters). Lucius determines that if the......

My Village

...Describe a village you know well I was born and have grown up in the country in a small village beside a beautiful river. My village is surrounded in a hedge of green bamboos. Most of the houses in the village are built of brick and have red tiled roofs. In the middle of the village there is an old pagoda with high trees around it. On the first and fifteenth days of the lunar month, the villagers often go to the pagoda to give offerings to The God of Agriculture. On the right of the village flows quietly a clear and blue river. When I was young, I used to swim in the river with my friends. How can I forget the wonderful time on this river fishing or rowing a boat with my boyhood friends! On the left of the village lies the village green where village meetings are often held by village officials. On this ground covered with soft grass we used to fly kites on windy autumnal evenings. The majority of villages live on agriculture. They get rich thanks to their fertile rice-fields and their diligence. Harvest time is certainly the busiest and the merriest time of the year. During the harvest, the villagers often get up very early in the morning. They cheerfully go to their rice-fields to harvest the bumper crop – the fruit of many months of hard work. My villagers are very friendly and helpful. They are willing to offer mutual help in any case and always get on with one another harmoniously. My village is rather small indeed but I like it very much because I......
