...Abstract: The rate of osmosis was examined through an experiment. Dialysis tubes were used to simulate a cell membrane. Solutions of 0.20 % and 0.40% sucrose were placed in each tube. The bags were placed into water and let to sit for three intervals of fifteen minutes. In the first bag that had no sugar solution, it had an osmosis rate of -.04 g/min. In the second bag that had 20 percent sugar solution, it had an osmosis rate of .09 g/min and the bag that had 40 percent of sugar solution had an osmosis rate of .11 g/min. What was concluded from the results is that the more percent of sucrose solution, the higher the rate of osmosis will occur and the lower the percentage of sucrose solution, the lower the rate of osmosis. Introduction: In order to understand the process of osmosis, proper terms must be defined. The first term was osmosis itself, osmosis is defined as the passive transport that refers to the diffusion of water across a selectively permeable membrane (Reece, 2009). Then of course, there are three different cases of osmosis which were defined. Hypertonic is a solution with a higher solute concentration. Hypotonic is a solution with a lower solute concentration. Isotonic is when the cells solute concentration is equal. The volumes were all made possible to increase or decrease via the plasma membrane, the plasma membrane defined as a flexible boundary between the living cell and its surrounding (Reece,2009) The dialysis tube represents the plasma membrane and...

...Essay on diversity Best Answer: I really like your work; however, some changes have been made after reading it the second time. The changes are in capital letters. Good Luck! Being different is the essence of humanity. Therefore it should never be the source of hatred or conflict. The answer to being different is to respect it. THEREIN lies a fundamental principal to peace; respect for diversity. We are all different yet want the same things for each other; to be respected by others. We should respect everyone that is different from US and respect their beliefs, traditions, values and opinions. In some ways, all these things put together MAKE us unique in who we are. Therefore we need to embrace our differences and uniqueness. I grew up in a small community in Southern Texas where most of the individuals were of Spanish heritage. We all interacted with one another regardless of our economic status or ethnic backgrounds. My FAMILY’S background is mixed. My mother is Mexican American and my father is African American. I only experienced the Mexican part of my heritage because I was raised by my mother. I can never escape my heritage as it is a major part of who I am. My heritage is everywhere around me. It is in our names, the foods we eat, the way we dance, sing, move, and interact with each other. For example, I enjoy listening to the music, Mariachi dances, and learning how to speak Spanish fluently. I enjoy eating Spanish foods like enchiladas, tacos, and chimichangas...

...Jumping off a high dive feels like a roller coaster going at high speeds. It could really be exhilarating. Some people may be scared of the diving board. Others may be brave and get through the obstacle as quickly as possible. It seems really cool to me which led to this day, which did this event take place. It was just a regular day playing with my friends at a pool center. I searched what I was going to do for fun. Then, my eyes were locked onto the high dive. I speed-walked to the high structure to prevent lifeguards from blowing the whistle at me. The line wasn’t that long, but it took time. Finally, I was up next in line for an adventure that awaits me. This is going to be my first time jumping off the high dive. My stomach felt like doing insane flips to make me back off going on the board. I climbed up the steep ladder, feeling more nauseous coming my way. Slowly and slowly, the ground got smaller like a penny. My stomach felt like doing more flips, my legs got shaky, and sweat dripped down from my head. Then I could hear my friends below....

This of course is really important since it will be the food and drinks I will be living from for the upcoming weekend. The dive system is a system which allows you to let your consciousness enter a game. This of course became popular real quick. It was expensive though, it cost 15000 dollar! It cost me an entire 2 years of saving while practically living of nothing to buy the system. There were other cheaper options but they were not that good compared to the 15000 dollar system. There are allot of games for this platform but I mostly only play ARD. It is the standard fantasy game, but it was the first game in it’s genre which did things just right.

...Fortune 500 Companies Nose-Dive in the Chinese Market Candice Tabb International Business MGMT 338 5 December 2014 Duane A. Beaudoin Abstract Fortune 500 companies Home Depot, BestBuy, and Mantel have all failed in the Chinese market. External forces such as competitors and sociocultural effect the companies’ ability to overturn a profit resulting in a complete withdraw. The ideal profitability of China’s market has shown resistance to standardized companies. The unwillingness to adapt and conform to consumers and the lack of preparation on all three companies serves as a lessons learned and displays the true setback of standardizing a product vs. adapt or formulate a new. Fortune 500 Companies Nose-Dive in the Chinese Market China’s Foreign Direct Investment (FDI) and its economy have changed dramatically since the 1980’s. Revolution was widely due to the reform era lead by Deng Xiaoping. During the early 1980’s FDI was restricted to a small number of markets in certain regions. FDI policies evolved with time in the mid 1990’s and in the millennium, government policies relaxed and unified with domestic companies. Foreign companies are enticed into the Chinese market by its rising gross domestic product (GDP), favorable foreign exchange regulations, licensing requirements, tariffs, and taxes (Hale & Long, 2012, p. 2) Many U.S born businesses hop on the bandwagon in globalizing in economically stable countries. Hamlin & Li (2010) stated, “In 2010, China...

...| | | | | Corporate Insight: Subway success dives in Asia-PacificWritten by Euromonitor International The Subway fast food chain has experienced an exceptional period of growth since 2001 in prominent Western markets. Pitching healthy convenience food to increasingly diet conscious consumers, the chain's aggressive franchising tactic has seen it achieve dynamic sales growth and even overtake an established fast food giant within the competitive US market. With global expansion central to Subway's agenda, its current formula is stumbling in Asia-Pacific, questioning the portability of its hitherto successful strategy. Subway, owned by Doctor's Associates, is the number one franchising opportunity of 2006, according to Entrepreneur Magazine. After opening its first US franchise in 1974, a modest nine years after its original site, the company's major growth period has occurred during the past five years, with 4,000 franchises opening worldwide in 2004 alone.Despite a general slowdown in the US fast food industry, which grew at a mere 3% per annum average between 2001 and 2004, Subway bucked the trend with an impressive average annual growth rate of 12% during the same period, making significant progress against the industry leviathans. While Burger King's value sales were nearly US$4 billion more than Subway's in 2001, Subway grew by a healthy US$1.8 billion in absolute terms for the period. In 2003, it overtook Wendy's to become the US' third largest fast food brand...

...Microsoft Corp.'s Windows OS last month took its biggest market share dive in the past two years, erasing gains made in two of the past three months and sending the operating system's share under 90% for the first time, an Internet measurement company reported today. In November, 89.6% of users who connected to the Web sites that Net Applications Inc. monitors did so from systems powered by Windows, a drop of 0.84 of a percentage point from October. The decrease was the largest slip by Windows in the past two years and easily bested other recent down months, including May 2008 and December 2007, when Windows lost 0.51 and 0.63 percentage points, respectively. Apple Inc.'s Mac OS X, meanwhile, posted its biggest gain in the same two-year period, growing by 0.66 percentage point to end the month at 8.9%. November was the third month running that Apple's operating system remained above 8%. Vince Vizzaccarro, Net Applications' executive vice president of marketing, attributed Windows' slip to some of the same factors he credited with pushing down the market share of Microsoft's Internet Explorer browser. "The more home users who are online, using Macs and Firefox and Safari, the more those shares go up," he said. November was notable for a higher-than-average number of weekend days, as well as the Thanksgiving holiday in the U.S., he said. Windows' share typically falls on weekends and after work hours, as users surf from home computers, a larger percentage of which run...

...MBA 602 International Business Section: 960 IB News Article 11/29/12 Japan Dives into Trade Talks ASEAN leaders begin RCEP negotiations Summary: An effort is being negotiated currently to launch a new regional comprehensive economic partnership called RCEP. The concept is this: to engage 16 Asia Pacific nations for free trade and to establish a trilateral free trade agreement with China and South Korea. Negotiations in this landmark free trade pact are taking place now in Phnom Pehn following the ASEAN Summit. If or once it is formed the RCEP is likely to cover half of the world’s population and would be the largest regional trading arrangement in the world to date. The RCEP is a strategy aimed at maintaining regional growth by ensuring that markets of the participating countries remain open and competitive. It is estimated that Japan’s GDP will grow by 1.1 percent with a wide range of partnership frameworks: tariff reductions and intellectual property protection. Under RCEP, which is different from individual country to country rules, there is a unification of rules and simpler business transaction procedures. The potential free trade agreements between ASEAN and China, Japan, South Korea, India, Australia and New Zealand could eventually lead to the creation of an integrated market that spans 16 countries with a combined market population of more than 3 billion people and a combined GDP of about US$19.78 trillion based on 2011 figures. The barriers...

...Master Diver Diving Equipment Open circuit demand scuba is the most commonly used by recreational divers, but closed circuit and semi-closed rebreathers are now available. Test Pressure: the pressure to which the cylinder is subjected to during hydrostatic testing. For a 200 bar cylinder it is 300 bars, for a 232 bar cylinder it is 348 bars. If internal inspection reveals corrosion, it may have to be cleaned by tumbling. The tumbling process involves filling the cylinder approximately half full of an abrasive material such as carbide chips, or aluminum oxide chips, and rotating it for a number of hours. A dual valve for a single cylinder, known as a Y-valve, or an H-valve, allows a diver to mount 2 regulator systems on a single cylinder. The first stage reduces cylinder pressure to an intermediate pressure (or low pressure) of approximately 90-150 psi (6 to 10 bar). The second stage reduces the intermediate (low) pressure to ambient pressure. Because of their tendency to fail in a closed position, upstream valves are rare in modern scuba regulators. In a Balanced Valve regulator the operation of the regulator is independent of the cylinder or applied pressure. (Breathes the same at low tank pressure) The internal valves of scuba regulator first stages are available in 2 basic types, diaphragm and piston. The main valve of a Pilot Valve regulator is opened and closed with air pressure, rather than mechanical leverage. Some regulators may...

...of a Plexiglass dome placed at the surface of the water, where air was drawn through the dome at the rate of 475 L min^-1. The amounts of carbon dioxide and oxygen were recorded using a Sable System and CA-1B analyzers, that were connected to a 500H flow generator. The measurements were taken every .5 seconds that elapsed. The data the was collected was analyzed using LabAnalyst X, and the rate of oxygen consumption was determined by the change in the concentrations of gas from the baseline level. Pre-dive metabolic rates were recorded when each sea lion was at the surface of the water resting and in the dome, and this measurement was collected during the last two minutes of a resting period of 5-10 minutes. Rates of oxygen consumption post-dive were collected to represent the amount of oxygen used during the dive as well as the amount of oxygen used to return within 5% of the recovery time. The average metabolic rate was determined by the dive cycle and the duration of the dive cycle, and was calculated by...

...into the rebreather eliminates the risk of nitrogen narcosis when operated within recreational limits. This frees individuals to enjoy the diving experience, which was unheard of before the invention of the rebreather. By controlling and maintaining the partial pressure of the gasses, one breathes at depth, thus restricting the nitrogen loaded into his or her system. After the dive, the circulatory system is cleaner than when the diver entered the water. The air all humans breathe contains 21% oxygen, 79% nitrogen, and slight trace gases. Circulatory systems maintain these averages. However, when using a rebreather, it changes these parameters to 45% oxygen and 55% nitrogen at a prescribed depth. Imagine the consequences; divers will no longer have a "NO-FLY" restriction after diving, so the long- anticipated diving vacation can be enjoyed right up to the time the flight leaves. The only thing that stands between them and experiencing the Closed Circuit Rebreather diving vacation is training. Closed Circuit Rebreather Closed circuit rebreathers will revolutionize the dive industry. Individuals will experience a longer, more comfortable diving experience, with safety features that can eliminate nitrogen narcosis when diving within recreational limits. Before the invention of the rebreather, all divers experienced nitrogen narcosis in some form. The latest evolution to be introduced into the Self Contained Underwater Breathing...
