Introduction Atomic Absorption Spectrometer (AAS) is an analytical equipment commonly used for the detection of heavy metals in particular sample. The first step to analysis in the AAS is the atomization of the desired element by converting it to a gaseous state. The atoms then absorb the energy emitted from the hollow cathode lamp corresponding to the desired element and a detector reads the signal and records the results. The results may be used quantitatively or qualitatively depending on the

Although the Muji shark fin soup cannot sell in Hong Kong and Taiwan in Asia‚ we still can buy it in Japan and we all know the number of sharks is decreasing sharply. Therefore‚ we suggest that Muji should substitute the real shark fin buy some other food which has the similar texture and taste‚ just like the artificial shark fin made of edible gelatin‚ in order to reduce the number of deaths of sharks because their shark fin have to make into food. Also‚ we suggest that Muji can motivate and sponsor

Go Green‚ Save Green We all realize that the planet is definitely changing and resources‚ such as money‚ and oil don’t come around as easily as it once may have and with the prices of virtually everything on the rise the least bit of extra cash can be the most bit of helpful. With only a few small adjustments to your daily routine we can lower energy costs‚ save money and ultimately help save the environment as well. While global warming and the oil peak aren’t the first things we think about

an urgent need to practise green consumerism and put the earth on a recovery path. How can one become a green consumerist? A green consumerist is one who believes in‚ buys and uses products that are safe for environment. Many people feel they are true friends of the environment just because they recycle bottles‚ newspapers‚ plastics and cans or buy unleaded petrol or environmentally friendly items. If that is all they do‚ then such people only pay lip service to green consumerism. Practising recycling

A few of the smaller/privately owned competitors (Cosi and Quizno’s) were able to operate in niche markets selling gourmet sandwiches and salads. The emergence of smaller restaurants offering easy access to exotic foods such as sushi and burritos created a more specialized niche market. 2) Size and Growth; With the emergence of these sub-markets and niche markets‚ McDonalds started losing market share. It now had to share its fast-food mass market

Abstract Green computing is the study and practice of using computing resources efficiently. The goals are similar to green chemistry; that is reduce the use of hazardous materials‚ maximize energy efficiency during the product ’s lifetime‚ and promote recyclability or biodegradability of defunct products and factory waste. Taking into consideration the popular use of information technology industry‚ it has to lead a revolution of sorts by turning green in a manner no industry has ever done before

Dahl 1 To Go Green or Not to Go Green? Very few people know the real definition of organic food‚ and most just call it “natural”. However‚ farmer J.I. Rodale describes it as: A system whereby a fertile soil is maintained by applying nature’s own law of replenishing it- that is‚ the addition and preservation of humus‚ the use of organic matter instead of chemical fertilizers and of course the making of a compost pile.(Schultz 35) In short‚ the difference between organic and non-organic

Atomic Spectroscopy using a Constant Deviation Spectrometer with Fabry-Perot Etalon Abstract A constant deviation spectrometer with Fabry-Perot etalon has been used to investigate the various atomic emission characteristics from a Zn-Cd-Hg lamp‚ a low pressure Hg lamp and a Ne lamp. The Fabry-Perot etalon of Free Spectral Range 0.010 cm-1 was used to resolve the fringes of the Hg 546.0731nm spectral line‚ and the 594.4834nm‚ 614.3063nm‚ 640.2246nm and 650.6528nm spectral lines of the Ne lamp
