source of chitosan. The water binding capacity (500%) and fat binding capacity (396%) of prepared chitosan are good agreement with the commercial chitosan. FT-IR spectra gave characteristics bands of –NH2 at 3431cm-1 and carbonyl at 1661cm-1. X-ray diffraction (XRD) patterns also indicated two characteristics crystalline peaks approximately at 10° and 20° (2θ).The surface morphology was examined using scanning electron microscopy (SEM). 4|Page Preparation of Chitosan from Jazan Area Shrimp wastes

D24BT8 Structural Biology Essay - What is the future of structural genomics in academia and industry? Cera Wong April 3‚ 2013 Structural genomics (SG) programs were formed by development of structure biology in large scale. Targets were selected from a specific genome‚ topologically similar types of proteins or protein families. (REF: Maksymilian) SG programs have developed more accurate and efficient methodologies on structure determination over the last decade (REF: Maksymilian)‚ where many

between Wilkins and Franklin on her role. Franklin was Wilkins’s equal‚ but he believed she was an assistant. This led to hostility in their relationship‚ and possibly changed the course of her career. Franklin continued her research using the x-ray diffraction techniques she was taught in Paris on DNA and made tremendous discoveries using the technique. First‚ Rosalind discovered that there are two types of DNA and that the combination of them makes x-rays blurry. On May 2‚ 1952‚ Rosalind’s research student

the broken pencil effect that can be observed when a pencil is placed in a glass of water. The pencil seems to be "broken" at the surface of the water as the light waves go from the air to the water. Diffraction is the bending of waves around a barrier or through an opening. The amount of diffraction a wave experiences depends on two factors: the wavelength of the wave and the size of the barrier or opening the wave encounters. Sound travels around corners because it has relatively larger wavelengths

Since light has a dual nature‚ it can travel both like a particle and like that of a wave. As the light travels from a person’s eyes‚ images can be form as it is reflected by the mirror. Properties such as reflection‚ refraction‚ interference and diffraction is identified in this study. Mirrors being specifically used as an optical instrument‚ gathers light and forms images‚ and is therefore the most common apparatus used in observing the porperties light particels and waves have. Similarly‚ we see
