EXPERIMENT 3: IDENTIFICATION OF FOOD CONSTITUENTS IN MILK. INTRODUCTION: In this experiment two milk samples are given and its compositions are tested using different methods such as using benedict solution to test the presence of reducing sugar‚ using copper II sulphate to test the presence of protein‚ using K3( to test the presence of fat. However in this experiment‚ not only are the milk tested for its composition‚ the amount of the particular substance such as reducing sugar‚ protein and

Raw materials consist of glass‚ so much has disadvantages‚ such as: easily broken‚ and easy to distribute the heat. This heat needs to be neutralized by other components that serve as a coolant. And with the additional component‚ the computer finally appeared to be a big‚ heavy and expensive. In 1946

affects the middle ear and is called otitis media. The Eustachian tubes inside the ears become clogged with fluid and mucus. The resulting pain and itching can become almost unbearable‚ causing difficulty sleeping and leaving you even more miserable the next day. If you are at your wits end on how to sleep with an ear infection‚ here are some useful tips to help ease the discomfort. How to Sleep with an Ear Infection • Since the eustachian tube for the infected ear can only drain into the throat‚ try keeping

Static system A pitot-static system is a system of pressure-sensitive instruments that is most often used in aviation to determine an aircraft’sairspeed‚ Mach number‚ altitude‚ and altitude trend. A pitot-static system generally consists of a pitot tube‚ a static port‚ and the pitot-static instruments. Errors in pitot-static system readings can be extremely dangerous as the information obtained from the pitot static system‚ such as altitude‚ is often critical to a successful flight. Several commercial

Introduction History: The audio amplifier was invented in 1909 by Lee De Forest when he invented the triode vacuum tube. The triode was a three terminal device with a control grid that can modulate the flow of electrons from the filament to the plate. The triode vacuum amplifier was used to make the first AM radio.[2] Early audio power amplifiers were based on vacuum tubes (also known as valves)‚ and some of these achieved notably high quality (e.g.‚ the Williamson amplifier of 1947-9). Most

years after the War. And for not being widely known it had little direct influence on the development of later computers. "Page 22" 3. Two problems associated with vacuum tubes are that they are very power consuming devices and the size of the vacuum tubes. "Video - Part 3" 4. Transistors were better than the vacuum tube because they were smaller‚ faster‚ more reliable‚ and cheaper to mass produce. But the problem with transistors was they still have to be hand-wired which limits how small transistors
