mentioned below. The Education Act of 1961 was the result of the growth of Chinese secondary schools resulting from the laissez faire policy implemented by the British that allowed the Chinese to set up primary and secondary schools. (Santhiram R. Raman‚ February- April 2010) The purpose of the act was to give an ultimatum to all secondary schools to use English and Malay as their medium of instruction. Failure to do so will lead

of optical amplifiers. In doped fiber amplifiers and bulk lasers‚ stimulated emission in the amplifier’s gain medium causes amplification of incoming light. In semiconductor optical amplfiers (SOAs)‚ electron-hole recombination occurs. In Raman amplifiers‚ Raman scattering of incoming light with phonons in the lattice of the gain medium produces photons coherent with the incoming photons. Parametric amplifiers use parametric amplfication. Laser amplifiers Almost any laser active gain medium can

fractional distillation. Once the fraction has been collected it must then be dried. The dried distillate is finally tested to determine whether or not it has been dehydrated. The three tests used were infrared spectroscopy‚ Bromine chemical test and Bayer’s chemical test. The infrared spectroscopy showed a large narrow peak at 3062.12(cm-1) and 3020.71(cm-1) which indicates that there is a double bond present. To assure the results were correct the chemical tests were done. The Bromine test was found

Between the symptoms‚ melting point‚ and results of the infrared spectroscopy we were able to identify what analgesic Jasper ingested. Results: After receiving all of the information and comparing the results of the symptoms‚ melting point‚ and infrared spectroscopy we concluded that they analgesic he was given was ibuprofen

Title: - Infrared Spectroscopy‚ Boiling point and Melting point. Introduction: - Infrared spectroscopy has also made a break though in medicine. It used to evaluate the kidney stone diseases thus broadening the use of IR in different ways. The purpose of this lab experiment is to identify the unknown solutions using the Infrared Spectroscopy (IR)‚ boiling point‚ and melting point (1). The IR helps to determine the compounds such as a functional group. In order to analyze the compound‚ IR and melting

bottom and thus allowing it to be separated. The total amount of 1-bromobutane formed was 2.065 grams. In order to confirm that the reaction occurred correctly and that 1-bromobutane was formed‚ infrared spectroscopy as well as halide tests were performed on the product. Infrared spectroscopy works on the basis that different covalent bonds of molecules can stretch and bend. These bonds can undergo vibrations which require energy that corresponds directly with the energy absorbed from infrared
