This study aimed to investigat the effect of Carbon tetrachloride CCl4 and Nigella
sativa oil on histological changes of liver. It was used only (20) immature male rats. to study
the effect of Carbon tetrachloride CCl4 and Nigella sativa oil on changes. The rats were
randomly divided into equal groups as follows. First group was injected intra dermally with
0.1 ml, normal saline (two times per weeks). This group was considered as control group .The
second group was injected intra dermally with (Carbon tetrachloride CCl4 ml / 100g ) of body
weight for ( two times per weeks was injected for (8weeks) . The third group It was orally
given 0.1 ml dose of Nigella sativa oil, it was injected for (8weeks).The fourth group was
treated with Carbon tetrachloride CCl4 and Nigella sativa oil in the same previous way.
There was clear effect for Carbon tetrachloride CCl4 on liver, it was caused infiltrative cells
presented by lymphocytes and phagocyte, liver cells defect; like edema, necrosis and
haemolysis in liver cells, it was found catalytic effect in treated group with Carbon
tetrachloride CCl4 and Nigella sativa oil liver, It appeared in normal appearance and like the
control group. It showed catalytic effect in treated groups with Carbon tetrachloride CCl4 and
Nigella sativa oil , and little negative in the liver.

Correlating Optimum Stage Pressure for Sequential Separator Systems
Summary<p>A study to find the optimum separators pressures of separation stations has been performed. Stage separation of oil and gas is accomplished with a series of separators operating at sequentially reduced pressures. Liquid is discharged from a higher-pressure separator into the lower-pressure separator. The set of working separator pressures that yields maximum recovery of liquid hydrocarbon from the well fluid is the optimum set of pressures, which is the target of this work.</p><p>A computer model is used to find the optimum separator pressures. The model employs the Peng-Robinson equation of state (Peng and Robinson 1976) for volatile oil. The application of t</p>
