Seeking ways to diminish Egypt’s dependency on foreign oil imports, we had to look for the obvious resources to exploit. Oil shale is one of Egypt’s resources that are left abandoned and not used. This project is aiming at introducing both experimental analysis for oil shale in Egypt and the best production technique for it. This study is about experimentally analyzing different samples of potential oil shale fields in Egypt. Samples that are analyzed in this project are from two locations in Egypt: Quseir-Safaga and Abu-Tartur Western Desert, and they are compared to one of the best oil shale fields in the world, which is from Green River Formation Colorado. The experiments were done using AUC lab retort to experimentally determine the critical temperature that will lead to the maximum production using sudden and gradual change in temperatures, which turned out to be sudden change at 500°C. Thereafter, the degree of API gravity was calculated for each run. Then the oil samples were determined for impurities and liquid chromatography results in the Egyptian Petroleum Research Institute. Part two of the study plan has been included to determine the ultimate ways of producing efficiently, ecologically and economically.

The actin cytoskeleton plays a role in mobility of many different organelles in plant cells, including chloroplasts, mitochondria, Golgi, and peroxisomes. While progress has been made in identifying the myosin motors involved in trafficking of various plant organelles, not all of the cargoes mobilized by different members of the myosin XI family have yet been identified. The involvement of myosins in chloroplast positioning and mitochondrial movement was demonstrated by expression of a virus-induced gene silencing （VIGS） construct in tobacco. When VIGS with two different conserved sequences from a myosin Xl motor was performed in plants with either GFP-labeled plastids or mitochondria, chloroplast positioning in the dark was abnormal, and mitochondrial movement ceased. Because these and prior obser- vations have implicated a role for myosins and the actin cytoskeleton in plastid and stromule movement, we searched for myosin tail domains that could associate with plastids and stromules. While a yellow fluorescent protein （YFP） fusion with the entire tail region of myosin XI-F was usually found only in the cytoplasm, we observed that an Arabidopsis or Nicotiana benthamiana YFP：：myosin XI-F tail domain homologous to the yeast myo2p vacuole-binding domain associated with plastids and stromules after transient expression in N. benthamiana. Taken together, these observations implicate myosin motor proteins in dynamics of plastids and stromules.
