In this study, a total of twenty four phosphate solubilizing bacterial (PSB) colonies were isolated on the Pikovskaya’s agar medium from different effluent exposed sediment of river Ganga. The bacteria showing clear halo zones around their colonies were considered as phosphate solubilizers. Out of 24 phosphate solubilizing bacterial isolates, 4 potential isolates showing highest halo zone on Pi...

The relationship between variable-metric methods derived by norm minimization and those derived by symmetrization of rank-one updates for sparse systems is studied, and an analogue of Dennis's nonsparse symmetrization formula derived. A new method of using norm minimization to produce a sparse analogue of any nonsparse variable-metric method is proposed. The sparse BFGS generated by this method...

Biofertilizers have been used as sources to improve plant nutrients in sustainable agriculture. Experiments were conducted to evaluate the potential of phosphate solubilizing bacteria (PSB) Bacillus megaterium var. phosphaticum and potassium solubilizing bacteria (KSB) Bacillus mucilaginosus inoculated in nutrient limited soil planted with pepper and cucumber. Results showed that rock P and K a...

The size of 3D data stored around the web has become bigger. Therefore the development of recognition applications and retrieval systems of 3D models is important. This paper deals with invariants for 3D models recognition. Thus under general affine transform we propose in a first time determinants of three points to realize invariance under affinity. To solve starting point problem we needs Fo...

Phosphate solubilizing bacteria (PSB) possessing the ability to solubilize insoluble inorganic phosphates were isolated from rhizosphere soil. Eighty-one potential PSBs thus obtained were quantitatively screened for phosphate solubilization. Of these, four bacteria found to be efficient phosphate solubilizers, were selected for further evaluation, and found that they solubilize tricalcium phosp...

In this article a special attention is paid to the to the role of public service broadcaster in cultural diversity societies. The main aims of the author was answering the following questions: how cultural pluralism is implemented by the public service broadcaster in Switzerland? How the Swiss PSB implements the principle of cultural pluralism, particularly in the context of the access of natio...

s new ways of using biological material to solve difficult computational problems continue to emerge, several fundamental questions arise: Are these techniques practical? If so, what are the key appli-cations? Do the techniques scale to larger prob-lems? Do they give us anything more than a few elegant theoretical insights into the nature of com-putation? Ultimately, is this a productive endeav...

The discovery of any new gene requires an analysis of the expression context for that gene. Now that the cDNA and genomic sequencing projects are progressing at such a rapid rate, high throughput gene expression screening approaches are beginning to appear to take advantage of that data. We present a strategy for the analysis for large-scale quantitative gene expression measurement data from ti...
