The History of the Potato Chip One of the most recognizable snack foods is the potato chip. Who can resist this thin slice of potato‚ fried into a crisp then salted? Potato chips are delicious and very popular. They satisfy the taste buds of many by hitting all the essential characteristics of a good treat. They are convenient‚ easily found‚ salty‚ greasy‚ and come in a wide variety of flavors. It is hard to believe their invention was a mistake. When George Crum‚ a Native American chef in Saratoga

INTRODUCTION Electronics without silicon is unbelievable‚ but it will come true with the evolution of Diamond or Carbon chip. Now a day we are using silicon for the manufacturing of Electronic Chip’s. It has many disadvantages when it is used in power electronic applications‚ such as bulk in size‚ slow operating speed etc. Carbon‚ Silicon and Germanium are belonging to the same group in the periodic table. They have four valance electrons in their outer shell. Pure Silicon and Germanium are semiconductors

doctors be held to moral standards when practicing euthanasia‚ and if so‚ which ones? Is killing a patient any different than letting a patient die? Daniel Callahan has responded to philosophers such as James Rachels in his article‚ “When Self-Determination Runs Amok‚” and insists that recognizing the moral distinction between killing and letting die is crucial in evaluating whether euthanasia is permissible. Callahan discusses how euthanasia should not be permitted under any circumstances based on

Introduction Crude fat is the term used to refer to the crude mixture of fat-soluble material present in a sample. Crude fat also known as the ether extract or the free lipid content the traditional measure of fat in food products. The lipid materials may include triglycerides‚ diglycerides‚ monoglycerides‚ phospholipids‚ steroids‚ free fatty acids‚ fat soluble vitamins‚ carotene pigments‚ chlorophylls‚ etc. The common approach for total crude fat determination is based on the solubility of lipids

timing signals has become more and more difficult. Present-day transistors can process data so quickly that they can accomplish several steps in the time that it takes a wire to carry a signal from one side of the chip to the other. Keeping the rhythm identical in all parts of a large chip requires careful design and a great deal of electrical power. Wouldn ’t it be nice to have an alternative? Clock less approach‚ which uses a technique known as asynchronous logic‚ differs from conventional

The use of RFID Chips in humans Radio-frequency identification (RFID) chips are small radio-frequency electromagnetic fields that can be used in a product‚ animal‚ and humans to track location‚ transfer data‚ and to identify the object. These chips are as small as a grain of rice and can store over 2‚000 bytes of data. Some chips are powered by and read at short ranges via magnetic fields (electromagnetic induction). Certain chips use a local power source like a battery and some others that don’t
