Numerical analysis of geophysical data to uncover Precambrian belts and probably enclose mineral deposits is becoming once more communal in mining activity. The method founded on typifying zones branded comprehend looking for analogous areas. proposed work outlines a semi-automatic image processing system the structural investigation Bou Azzer inlier, which varies from preceding approaches as i...

Due to its unique geographic and tectonic location, the Bou Azzer inlier has drawn increased interest in mining studies. The inlier’s basement structure remains subject investigation meanwhile faults igneous rocks affect local geology. In order comprehend structure, we use aeromagnetic data. edge enhancement method described this work is based on gradiometry tensor analysis (GTA) of data, which...

A variety of results in complex geometry and mathematical physics depend upon the analysis of holomorphic sections of high powers L⊗N of holomorphic line bundles L → M over compact Kähler manifolds ([A][Bis][Bis.V] [Bou.1][Bou.2][B.G][D][Don] [G][G.S][K][Ji] [T] [W]). The principal tools have been Hörmander’s L-estimate on the ∂̄-operator over M [T], the asymptotics of heat kernels kN (t, x, y) ...

Two samples of vladimirite, one from Bou Azzer, Morocco, and the other from a new occurrence in Copiapó, Chile (designated as R100075 and R080001, respectively), were examined with an electron microprobe, single-crystal X-ray diffraction, and Raman spectroscopy. Our results show that vladimirite is monoclinic with space group P21/c and unit-cell parameters a 5.8279(2), b 10.1802(4), c 22.8944(1...

The hyporheic zone of river ecosystems provides a habitat for a diverse macroinvertebrate community that makes a vital contribution to ecosystem functioning and biodiversity. However, effective methods for sampling this community have proved difficult to establish, due to the inaccessibility of subsurface sediments. The aim of this study was to compare the two most common semi-quantitative macr...

The crystal structure of an oscillatory zoned erythrite sample from Aghbar mine, Bou Azzer, Morocco, was refined using synchrotron high-resolution powder X-ray diffraction (HRPXRD) data, Rietveld refinement, space group C2/m, and Z = 2. The crystal contains two sets of oscillatory zones that appear to have developed during epitaxial growth. The unit-cell parameters obtained are a = 10.24799(3) ...

Bangladesh Open University (BOU) is the only national institution in Bangladesh which is catering distance education in the country. It has extensive network through out the country to provide readily accessible contact points for its learners. After passing of 15 years since its inception, BOU has lagged behind in using technologies. In consideration of its limit to conventional method in teac...
