Abstract: The objective of this experiment is to use Gas Chromatography to distinguish between two enantiomers of carvone from caraway oil and spearment oil and to find the 2 carvone’s optical activity as well as percent carvone in spearment and caraway oil. It was found that S-carvone had an optical activity of 0.0047 and R-carvone had an optical activity of 0.516 and that spearment oil is 59% carvone and caraway oil is 100% carvone. Backround: Gas Chromatography separates organic samples much in

Box Coverts Beer Waste to Bio-Gas Cambrian Innovation has now come up with ways to easily convert beer waste into bio-gas‚ which can be used to power large scale factories‚ businesses‚ and even schools by using less energy. Matthew Silver‚ CEO of Cambrian Innovation studied bioelectric systems that could potentially be used to manage water in space‚ in doing so he saw a great opportunity to develop a certain microbe that could clean the industry’s water and make it reusable time after time.

a memo to the board of directors as follows The diversity of our products requires that we reorganize along our major product lines. Toward this end I have established three new divisions commercial jet engines‚ military jet engines‚ and utility turbines. Each division will be headed by a new vice president who will report directly to me. I believe that this new approach will enhance our performance through the commitment of individual managers. It should also help us identify unprofitable areas

Brayton cycle depicts the air standard model of a gas turbine power cycle and is used in all applications involving turbine engines; such as jet engines. A simple gas turbine is comprised of three main components: a compressor‚ combustor and a turbine. Air is compressed in the compressor‚ then mixed with fuel and burned under constant pressure conditions in the combustor. The hot gases created from this process are allowed to expand through the turbine to perform work. Low pressure air is drawn

such an environment‚ having the flexibility to augment gas turbine power output during periods when there is high tariff rates is of paramount importance to the profitability of the utilities. Efficient‚ clean and less expensive to implement than most other alternatives‚ combined cycle power plants offer a blend of operational attributes that makes it the best choice for power production. The generated power and efficiency of gas turbine plants depend on the temperature of the inlet air. At high

Europe seeks independence from Russian gas imports through shale gas in Poland – Demand shift & Free Market Competition Natural gas in Europe is a major source of electricity generation‚ domestic use (domestic cooking and heating fuel)‚ transportation‚ and is also used in the manufacture of fabrics‚ glass‚ steel‚ plastics‚ paint‚ and other products. Therefore‚ no industrial country can afford to be cut off from this supply‚ because it would result in a major loss of economic power and chaos for

Gas Tungsten Arc Welding The Process Gas Tungsten Arc Welding‚ also known as Tungsten Inert Gas Welding‚ is an arc welding process that uses a non-consumable tungsten electrode to produce a weld. The weld area is protected from atmospheric contamination by an inert shielding gas‚ such as argon or helium‚ and filler metal is normally used‚ except in autogenous welds. A constant-current welding power supply produces energy which is conducted across the arc through a column of highly ionized gas and
