Two main reservoirs are producing in Komombo Basin: the first one belongs to the C Member of the Six Hills Formation, and the second belongs to the Albian/Cenomanian cycle. The C Member reservoir lacks detailed studies. Therefore, a detailed study of this reservoir is needed. 3D geological reservoir modeling of the C Member reservoir can be a pertinent part of an overall strategy for the development of hydrocarbon fields in Komombo Basin. Five boreholes, three vertical seismic profiles and twenty 2D seismic reflection sections are integrated in Petrel™ modeling software for building 3D structural, facies and petrophysical models for the C Member reservoir. The constructed 3D structural model reveals the presence of two normal faults, in NW–SE and NE–SW directions. A detailed petrophysical evaluation was performed for the available wells. The resulted facies/petrophysical parameters are then used as input in the processes of facies and petrophysical modeling. The C Member reservoir exhibits thickness values ranging from about 91.5 to 426.5 m. The constructed 3D facies model of the studied reservoir depicts that the shale beds have the large probability distribution in the study area with the comparison of the sandstone and siltstone beds. The created 3D petrophysical models reveal that the C Member reservoir has a fair reservoir quality. This reservoir exhibits, generally, high water saturation values in most parts of the study area, while the hydrocarbon saturation is restricted to the depocenter of the basin.

Bisphenol A (BPA) is a chemical material that using in polycarbonate plastic that is widely used in daily life items. Several studies showed the adverse effect on the health of erythrocytes in both human and animals, while gallic acid (GA) is a known antioxidant capable of counteracting free radicals. In this study included 4 groups 10 rats each. The first was the control. The second received BPA in drinking water was given ad libitum at dose 40mg/kg.b.w. The third and fourth groups was given BPA by the same dose and by the same route in addition to receive GA in the diet at doses of 50 and 200 mg/kg.b.w, respectively. In erythrocytic hemolysate, the antioxidants: glutathione (GSH), activities of both superoxide dismutase (SOD) and catalase (CAT) were estimated. Also, lipid peroxidation (LPO) and carbonyl protein (CrPr) were determined. The results showed that BPA significantly increased LPO and CrPr and decreased the activities of CAT, SOD and the GSH content. However, the treatments of the BPA-intoxicated rats with GA reversed the erythrocytic oxidative damage and curtailed the decrease in antioxidants. In conclusion, the GA with both doses could attenuate the oxidative damage in erythrocytes of rats-treated with BPA.

A novel rhodamine-pyrazole based molecular probe was designed and easily synthesized. The probe could to detect several analytes in aqueous solution at biological pH (HEPES, pH = 7.2). Several heavy metal cations, including Cu2+, Fe3+, Al3+, Hg2+ and Ni2+ were detected discriminately by the probe. Also, the novel compound exhibited a good sensory selectivity towards S2O52− by both absorption and emission spectra. Moreover, probe/Cu2+ complex could to detect several anions, including F−, CN−, S2−, CH3COO−, CO32– and NO2−. Furthermore, the probe exhibited a high potential to work as a molecular system able to perform a number of logical operations such as AND, NAND, NOR and INHIBIT logic gates.

We reported here the unique ability of a Rhodamine 6G-based probe (3) to detect discriminately several targets, including H+,HO−, Cu2+, Hg2+, Fe3+, Co2+, Cd2+, Zn2+, Sn2+, Ni2+, Al3+, Pb2+, Ce3+and Ag+ , by unambiguously colorimetric and fluorimetric outcomes. In aqueous solutions, the presence of proton induced the ring-opening of rhodamine moiety but the presence ofhydroxide induced the conversion of 2-hydroxyphenyl hydrazone moiety from the non-fluorescent benzenoid form into the fluorescent quinoid form. The probe could to distinguish between different cations in DMF and to work like an artificial tongue at molecular level. Several logic gates including OR, INHIBIT and TRANSFER, were performed by the probe. Moreover, the probe is able to execute three INHIBIT logic gates by two inputs, which was exploited to execute a digital molecular comparator.
