Abstract The Greek-Roman Isis temple is located on the west bank of Luxor; Upper Egypt was made of sandstone and decorated with different kinds of wall paintings. It suffers from many causes of deterioration and degradation mainly ground water‚ salt weathering‚ and different types of dirt accumulations on the relives and paint surface such as soot‚ grease‚ wax‚ biodeteriorated colored patches‚ bat patches‚ waste of birds and even house fly specks. All these lead to the gradual disappearance of paintings

Light that is visible to the human eye is a small portion of the electromagnetic spectrum which can vary in colour based on the wavelength of what is being seen at any particular time. This visible light has a primary function of causing electrons to become more active with higher energy rates. The colour that is seen revolves around the size of this portion which is noted as the wavelength. White light is a culmination of all colours which is the cause of it being the brightest. Furthermore‚ when

monofunctional bidentate Schiff base have been synthesized and characterized through elemental analysis‚ conductance measurements‚ molecular weight determinations‚ UV-visible‚ multinuclear (1H‚ 13C‚ 119Sn) NMR spectroscopy‚ FT-IR‚ X-ray powder diffraction and theoretical calculations. On the basis of these techniques‚ it is proposed that the ligands are bounded to the tin atom through the azomethine nitrogen and carboxylate oxygen. The data reveal that triorganotin(IV) complexes have penta-coordination

Biophysicist Maurice Wilkins was born on December 15‚ 1916‚ in Pongaroa‚ New Zealand. He worked with the Manhattan Project before turning to biophysics. He produced the first image of DNA fibers. Also a conflict did occur between him and his colleague Rosalind Franklin‚ helped do the Watson and Crick double-helix model shared in 1953. Wilkins got the Nobel Prize for his work. He died on October 6‚ 2004. Early life Maurice Wilkins was born by two Irish parents. When he was born his father‚ Edgar

chemistry of quartz‚ α-FePO4 and β-FePO4. FePO4 is a quartz-type of iron phosphate. It is different from other α-quartz isotypes due to the fact that the A-cation is a transition metal. The low-temperature α-phase can be from 294k neutron powder diffraction to high-temperature β-phase 1073K. As the quartz start to transit at 980K‚ from α-β‚ the Fe-O-P bridging angles start to increase value and the tetrahedral tilt angle decline drastically. Due to the high intensity of thermal heat‚ it will turn to
