Not everyone is a tech enthusiast. Thus‚ the ultimate decision between a Mac and PC can be overshadowed by the constant rivalry between Apple and Microsoft. The truth is that Macs and PCs are very different‚ but similar at the same time. However‚ one of these systems will fit a person’s needs and wants better than the other one. When any person or company in the world is in the process of buying new computers or laptops for personal‚ school‚ or office use‚ they might not know which system to buy

What is X-ray Crystallography ? X-ray crystallography is an experimental technique that exploits the fact that X-rays are diffracted by crystals. It is not an imaging technique. X-rays have the proper wavelength (in th Å t ö (i the Ångström range‚ ~10-10 m) t be scattered by the electron cloud of an atom of 10 10 ) to b tt d b th l t l d f t f comparable size. Based on the diffraction pattern obtained from X-ray scattering off the periodic assembly of molecules or atoms in the crystal‚ the electron

The primary focus of experiment 4 was to teach a student the basic solubility rules of salts in aqueous solutions. After developing and using a scheme for the qualitative analysis of three cations in an aqueous mixture‚ a student would use a centrifuge to identify‚ precipitate‚ and separate the three ions in the mixture. After becoming familiar with all three cations‚ the student would use the scheme again to identify at least two of the cations in an unknown solution. In order to begin the separation

Experiment A Spectroscopic determination of Iron with Phenanthroline Unknown # 2 Mass of Mohr’s Salt: 0.2040 1. 5mL of 6M acetic acid was measured and transferred into a 100mL volumetric flask with a pipette and diluted to the mark. Concentration = [0.2040(±0.0001)g/100(±0.08)mL]*[(1mol/392.16g)/(1L/1000mL)] = 0.005202(±0.09382%) = 0.005202(±0.000005)mol/L 2. 10mL of the above stock solution was transferred to a 250 mL volumetric flask and diluted to the mark.

SEX DETERMINATION IN FORENSIC ODONTOLOGY Identification of living beings and dead bodies is of great importance in Forensic science. Sex determination is one of the important steps in establishing identity. Sex identification in international sports: In 1932 Helen Stephens and Stella Walsh: Hitler’s Olympics In 1936 Stella accused Stephens of being male and so a crude physical examination including gross physical examination of external genitalia was done. In 1966 gender identification became
