This paper study the ability of Enterobacter cloacae for degrading crude oil in contaminated water. Six isolates of E. cloacae were isolated from hydrocarbon contaminated soil and water of different sites. The isolate E. cloacae E1 showed the highest emulsification index (E24%) reached 62% thus it was chosen for further study. Biosurfactant produced by E. cloacae E1 reduced the surface tension of the medium from 64 to 36 mN/m. pH range 6.5 – 7 and temperature range 30˚C - 35˚C were the optimal conditions for maximum degradation. After 30 days of incubation, E. cloacae E1 degraded 70.00 ± 0.40% of the crude oil. GC-MS analysis revealed that E. cloacae E1 was able to degrade aromatic compounds. This study proved that E. cloacae E1 con

Different transition rates of the nuclear preequilibrium states in the exciton model
were numerically calculated in the present work, as well as the state density and matrix
element of the nuclear interaction. The calculations were based on the two-component
version of the exciton model. Some comparisons were made with earlier calculations,
and the results showed a good agreement. The results were explained on the bases of the
effects of the differences in the particle and hole numbers, as well as the type of the
incident particle and its energy. The conclusions indicated that preequilibrium nuclear
reactions induced by protons differ only by small fraction from those induced by
neurons at low exci

The ethanolic and aqueous extract from the fruit part of the plant showed antimicrobial activity against most tested microorganisms. The most active extract against Gram-positive bacteria

Tea is one of the important liquids that people drink. In Iraq, tea is the main beverage after water. The tea plant is known scientifically as Camellia sinensis, when planting and during growth needs to fertilizers, which contents remarkable amounts of Uranium. So it became important to study the concentrations of uranium found in tea. Eight samples of tea had been taking, which represent the most important species used in the Iraqi kitchen, and the Uranium concentrations were measured. The results showed that the average concentration of uranium for all samples were1.005 mg/L, while the average of the annual effective dose was 0.221 mSν/y. The results also indicated that green tea possesses small concentration of Uranium compared with
