The objective of this work is to show the contribution of multispectral remote sensing data to detect and distinguish the ophiolite rocks of Bi’r Umq and their geologic setting, southeast of Al Madinah Al Munawarrah in Saudi Arabia. This work includes detailed fieldwork lab studies, as well as processing operations, were performed on The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER 2006, 2007) and Satellite Pour L’Observation de la Terre SPOT 5 (2005) images of the study region. Among the processing techniques applied are band ratio, histogram stretching, the combination of spectral bands, image fusion. The techniques used permitted a clearly show that the ultramafic rocks are distinct from other rock units and contain important economic minerals. This research also illustrates the tectonic parameters and that the remains of the oceanic crust are exposed and juxtaposed to the rocks of the continental crust of the Arabian Shield. The results of the spatial data processing revealed a good positive concordance with the results of the field investigations.

In this study, the processing and mechanical properties of porous metal matrix composites(MMCs) composed of spheroidal cast iron chips(GGG40) and bronze chips(CuSn10) and formed by hot isostatic pressing were investigated. Bronze chips(CuSn10) were used as a matrix component, and spheroidal cast iron(GGG40) chips were used as a reinforcement component. The MMCs were produced with different CuSn10 contents(90 wt%, 80 wt%, 70 wt%, and 60 wt%). The hot isostatic pressing process was performed under three different pressures and temperatures. The produced MMCs were characterized using density tests, Brinell hardness tests, and compression tests. In addition, the consolidation mechanism was investigated by X-ray diffraction(XRD) analysis and scanning electron microscopy. The test results were compared with those for bulk CuSn10 and bulk GGG40. Mechanical tests results revealed that the metallic chips can be recycled by using hot pressing and that the mechanical properties of the produced MMCs were similar to those of bulk CuSn10. XRD and microscopy studies showed that no intermetallic compounds formed between the metallic chips. The results showed that the CuSn10 and GGG40 chips were consolidated by mechanical interlocking.

The effect of the valence band tail width on the open circuit voltage of P3HT：PCBM bulk heterojunction solar cell is investigated by using the AMPS-1D computer program. An effective medium model with exponential valence and conduction band tail states is used to simulate the photovoltaic cell. The simulation result shows that the open circuit voltage depends Iinearly on the logarithm of the generation rate and the slope depends on the width of the valence band tail. The open circuit voltage decreases with the increasing width of the band tail. The dark and light ideality factors increase with the width of the valence band tail.

·AIM: To investigate the possible effects of intracameral bevacizumab on oxidative stress parameters and apoptosis in corneal tissue.·METHODS: In total, 30 rats were assigned randomly into the following three groups of 10 rats each: a sham group(Group 1; n =10), a control group [Group 2;balanced salt solution(BSS) was administered at 0.01 m L;n =10], and a treatment group(Group 3; bevacizumab was administered at 0.25 mg/0.01 m L; n =10). The total antioxidant status(TAS) and the total oxidant status(TOS) in the corneal tissue and blood samples were measured, and the oxidative stress index(OSI) was calculated. Additionally, corneal tissue histopathology was evaluated for caspase-3 and 8 staining and apoptotic activity.·RESULTS: In the blood samples, the TAS, TOS, and OSI levels were not significantly different(all P >0.05).Compared with the sham and control groups, the TOS and OSI levels in the corneal tissues were significantly different in the bevacizumab group(all P 0.05).However, compared with the sham and control groups,greater immunohistochemical staining for caspases-3and 8 and an elevated level of apoptotic activity were observed in the bevacizumab group.·CONCLUSION: This study revealed that intracameral bevacizumab injections seemed to be systemically safe but may have elicited local toxic effects in the corneal tissue, as indicated by the oxidative stress parameters and histopathological evaluations.
