Because an overweight person displaces much fluid when stepping into a pool. By displacing more fluid, the person creates a greater buoyant force making it easier for him to swim.5.c) By placing a battery into the water with a floating rod into its tardily cylindrical cavity it is quite easy to determine the condition of the battery. The diluted batt ery will have a much higher concentration than that of a highly charged battery. From the observation of how the battery floats you can retell its condition.8.) We were able to find the volume of displace water in surgical incision II quite easily. First we placed a large tupperware container on the table and in it a small container filled to the top with water. When the cylinder block of wood was placed in the container, water fell out of the smaller container into the larger container. By placing the water which fell out of the smaller container into a cylinder, you are able to measure the volume of displaced water.9.) No I did non use Archimedess principal to find the densities. I used the density formula of dividing the mass by the volume. We find the densities and compare them to the densities of water to foster understand the mechanics of buoyant force.DiscussionIn part dickens of the lab dealing with Archimedess principle, we were comparing the buoyant force of a bloc k of wood to its weight in dynes. The first step of the appendage dealt with measuring the quantity of displaced water. We did this using two containers, bingle small and one large, and filled the small container to the brim with water. By placing the block of wood in the small container and using a graduated cylinder, we were able to find the marrow of water displaced by the block.

The Implicat of Sin in Nathaniel Hawthornes The Scarlet Letter :: Scarlet Letter essays

Down Syndrome :: Biology Chromosome Disorders

Karyotype is the feature article chromosome complements of a eukaryotic species and they are arranged in homologous pairs. at that place are many abnormal chromosomes and some of them are Turner syndrome, Klinifelter syndrome, Edwardss syndrome, Down syndrome and Patau syndrome. The abnormal chromosome that I was given was called Down Syndrome or trisomy 21. We could bonk this illness by looking at the Karyotype because a normal karyotype has two- 21 chromosome but in Down syndrome there are three- 21 chromosomes. My Karyotype graph represented a male. I realized this because there was one X chromosome and other one was Y chromosome. The disease assigned to me was caused by wake up chromosomes which affects both males and females. The Down syndrome could be notified before a child was born. The symptoms of this disease vary more that 50 characteristics. The general characteristics were the growth of the child which would be slower than the average, weak muscles, excess fat and s kin, forgetful arms and short legs. The facial features of the people with down syndrome was also different from the average, such as small and low set ears, irregular shaped mouth and tongue, create from raw material built-up on the iris and irregular or crooked teeth, which was produced late. It would be clean easy to understand the cause of Down syndrome (DS). Most people fork up 23 pairs of chromosomes (total of 46), but a baby with Down syndrome had 47 chromosomes. mavin of the two parents might be a balanced carrier of translocation. This would pass when translocation of 21 chromosomes attached to another chromosome. There is no specific intervention for Down syndrome at present, but the technology will find a solution soon, for such diseases. There is a handling which is called Down syndrome treatment and it focuses on controlling the symptoms and the characteristics of the syndrome.

The Alaskan wilderness :: Environment, Fishing, Hunting

The Alaskan wilderness is one of the most polemical topics discussed in the United States today. There ar many different opinions and regulations pertaining to certain topics alter the natural landscape of Alaska. One such topic is plying for brownish strike. While these massive animals face no current danger of existence wiped out as a result of hunting, it is still a controversial and constantly debated issue. Over ninety-five percent of the United States brown bear resides in Alaska. Brown bears ar one of the more appealing attractions for visitors to Alaska. concord to the Alaskan Outdoor Journal, there atomic number 18 places all throughout Alaska that are designated brown bear viewing areas (Alaska Outdoor Journal, 2010). However many who stick to Alaska for the brown bear dont simply mother to observe. Instead, they come for the hunt. These animals are constantly hunted for sport, and since they reproduce at a really low rate, this has the potential to jeopardize the total commonwealth of the brown bear. Overall, I believe that brown bear hunting should remain legal.According to the Alaska part of Fish and Game, the brown bear is located all throughout Alaska, by and large in areas that allow them to seasonally hunt salmon (Alaska Fish & Game, 2010). This allows them to move around larger and live in higher concentrations than the grizzly bear. The traditional brown bear and the grizzly bear are actually both categorize as brown bears, despite having several differences in appearance. Brown bears are one of the most fascinating and powerful species in the Alaskan wilderness. Cubs are usually born during January or February, usually in groups of one to quadruplet (Alaska Fish & Game). A fully grown, male brown bear trick weigh up for 1,500 pounds and be over 10 feet in elevation (Alaska Fish & Game, 2010). Brown bears also have the ability to run at speeds up to 40 mph for short bursts of time (Alaska Fish & Game). all in all of these unique characteristics make many people upset that it is legal to hunt them. There are several groups that are working to conserve the brown bear population, particularly in Alaska, such as The Northern forums Brown Bear Working Group (Fish & Wildlife Journal, 2010). The bear population in Alaska is thriving and is classified as a status of to the lowest degree concern, by the IUCN Red List (IUCN, 2010). Overall, the brown bear population faces no danger whatsoever.

The Future of P2P Technology and Music Essay -- Napster Internet Music

The Future of P2P Technology and MusicSince 1999, the situation around unison has been changed drastically. In that year, the novel computer software program Napster was released. With this software, people became able to get any send they want easily, sometimes illegally. Some musicians and people in the entertainment sedulousness have tried to exterminate that P2P Peer to Peer engine room. But it looks as if their efforts are in vain. People are going to use P2P technology more and it might as well wrench the official room to handle music distri saveion. The music manufacturing should rather take improvement of the technology than keep trying to exterminate it.Originally, Napster was a kind of archive share software. File sharing software had been developed as database managing software. As the internet has grown so huge all over the world, a distributed database system model has been proposed as the preferring system. The file sharing P2P software has become the celebr ated information tool for storage system. But now, rapid egress of broadband and the ability to be anonymous on the internet menace the entertainment industrys control of the distribution of such products as movie and music. We can get music or movie files with P2P software through the internet for free.The entertainment industry and many musicians regarded P2P as a big crisis for copyright, so that they sued the company that produced Napster. Anger leads Metallica to the Internet, an article by Karen Schubert in the States TODAY, noticed that heavy-metal band Metallica was suing Napster. And now some people in the music industry are fighting with a distributor of P2P software even in the Supreme Court, and lobbying to outlaw P2P technology.

Diary of Mrs. Amelia Stewart Knight :: essays research papers

Response on Diary of Mrs. Amelia Stewart KnightWhen I finished this phrase I started to realize that the life of pioneers was not just one fine-looking adventure, but they had to face some really difficult problems like mordacious river crossing, bad weather, different kinds of accidents and diseases along the way without any chance for medical checkup treatment.But first of all I had make a look to answer one question before all the problems along the way. It is how much(prenominal) did pioneers traveling west needed and how long did they overhear to safe priggishty to be able to support their trip. It took roughly $800-$1,000 to obtain a proper outfit ( butterball, food, clothing, etc.) and enough supplies to live a unit year without place or harvesting a crop. Some families take overd for three to quintette years before being able to begin their trip to west. From tap point of view they had to be very patient and live more or less in poverty to be able to save such a big amount of money. That means that most of batch had a lot of problems even before they started they trip to west.Another dandy surprise for me was that most people walked and made the entire 2,000- cc journey on foot because most emigrants grossly overloaded their wagons and that is why only a few(prenominal) could ride in font the wagons. Most of emigrants who could ride inside were children and women. To ride in a wagon sounds really better than walking all 2000 mile on foot, but another(prenominal) problem which they had to face was that the emigrant wagons didnt have any safety features. If someone fell under the massive wagon wheels, death was instant. Many lost their lives this way and as I mentioned to a higher place most often, the victims were children.Farther more the river crossings, which were necessary to get to their point, were a ceaseless source of distress for all members of the group. Hundreds drowned trying to get wagons, cattle and another stuff to the other shore.Perhaps the biggest problem on the Trail was a deadly disease with no cure at that time, called cholera. This disease was a really big threat, not only for an individual, but also for the whole group. First of all its very contagious and secondly the regorge person would slow down the whole caravan. Sometimes they received a proper burial, but often, the sick would be abandoned, in their beds, on the side of the trail and die alone.
