diffusion. Gas and solute exchange surfaces in humans have been adapted to maximise their effectiveness. The larger an organism gets and the more complicated it is which makes it harder for materials to be exchanged. Gaseous exchange is the process by which oxygen is taken in by the body for respiration and carbon dioxide‚ the waste product of respiration‚ is released. In humans the lungs are the organ used for gaseous exchange. When we breathe‚ air moves in and out of the body via our lungs. In

The Natural Gas Case Introduction * This case is about the negotiation of buying a gas between two parties involved – the plaintiff a German company and the defendant an Austrian partnership. On the 18th of December 1990 the plaintiff faxed the defendant with an offer to buy 700-800 metric tons. Meanwhile Austria responded that the ship will be from US for delivery to Belgium and the price is $376 per tone. Additionally a letter of credit was required‚ since both of the parties haven’t seen

Gas chromatography (GC) is a chromatography technique where the separation of individual components (analytes) from a sample relies on their differing distribution between a mobile and stationary phase. The mobile phase carries the analytes through the stationary phase. In GC‚ it’s an inert gas (usually helium or nitrogen). The gas must be inert‚ so it won’t react with the sample to give a false reading. The stationary phase is a substance fixed in place to which the sample adsorbs because

Biogas as used in two different systems: an instant‚ gas water-heater used to generate hot water for farm use‚ and a modified piston engine driving an electrical generator of one phase‚ I kW output‚ fuelled directed by the gas. Operation of both systems was satisfactory. The unit is being used to demonstrate the technology for potential users (mostly farm owners). Key

surveys‚ weather studies‚ gas analyses and research of the atmospheres of other planets. They are usually made of glass or plastic‚ and while most are scored for measurement‚ some can measure changes digitally. The single-tube manometer measures only the pressure of a liquid‚ since there is no alternate place to compare gases. A U-shaped manometer essentially pits two different gas pressures against one another‚ and measures the strength of the captured gas. The free-flowing gas is usually air at the

Work to live‚ Don’t live to work By Will Brady This is my response to a QCS(Queensland Core Skills) test. When we walked into the test room we had no idea what we were supposed to write about. We were give the theme of ‘Time’‚ for which we were given a stimulus sheet and 2 hours to write whatever we could. I came up with this. These days‚ most of us spend three quarters of our lives‚ working. And what is all of this work for? To save money so that when we retire‚ and were old and crippled‚

Where will you live? Most everyone will ask that question at some-point in his or her life. Will it be the urban life of the big city‚ filled with its tall buildings‚ loud neighborhoods‚ busy streets‚ and never-ending projects? It might be that that is more than one might want if that is the case‚ there is the serenity of the suburbs‚ which offer spacious housing‚ peaceful surroundings‚ fresh air‚ and plenty of nature. Both urban and suburban areas offer people different choices in lifestyles‚ from

Sansui-ga is a form of Japanese monochrome landscape paintings‚ the preferred genre among Zen painters in the 14th-16th century. Sansui-ga painting is done in Chinese-inspired sumi-e or suiboku-ga‚ an ink wash painting style‚ which uses black ink in various concentrations. Gradations of ink are used to create a sense of light and shade‚ as well as modulated brushstrokes and lines to create a sense of volume and rhythm. (Parent) Vast landscapes on screens and sliding doors set a serene and contemplative
