Four phosphate-solubilizing bacterial strains viz. Pseudomonas fluorescens BAM-4, Burkholderia cepacia BAM-6, B. cepacia BAM-12 and Aeromonas vaga BAM-77 were isolated from the rhizosphere of pearl millet (Pennisetum glaucum, cv. Raj 171), mung bean (Phaseolus aureus, cv. RMG 492) and sesame (Sesamum indicum, cv. RT 46). To the best of our knowledge, this is the first report on phosphate solubilization by Aeromonas vaga. Seed inoculation of mung bean with or without tricalcium phosphate (TCP) was performed to study the effect of single and dual bacterial inoculations in pot trials having sterilized sandy loam soil, and was found to enhance the growth and yield of plants. The results were on a par with chemical fertilizer, single superphosphate (SSP) and commercial biofertilizers, PSB (Bacillus polymyxa) and MC (Pseudomonas striata), used as standard reference. Addition of TCP to soil gave better results and dual inoculation was more effective than single inoculation of bacteria. Among the four strains studied, A. vaga and P. fluorescens were found to be more valuable as single inoculants in terms of plant growth, whereas in combination treatments, P. fluorescens along with B. cepacia and A. vaga performed very well both in the presence and absence of TCP.

The number of turnours on every patient was either single or multiple and each increased in size daily. The growths were unique in their fulminatingtype fleshy mass, with a consistency va ying from soft to firm, absence of purulent material or head, and extension up to the fibrous layer covering the musculature. Histopafhology was suggestive of granulomatous rather than a suppurative nature of Ihe lesions. Isolation of MRSA from the burn wounds of four cases on the first day of dressing and then from the surface of the tumours of all of them and the excised tissues, as well as from the environment of the dressing room, indicated its involvement in the causation of the growths through contaminations of wounds with a hospita! endemic strain while handling or dressing. The organisms were resistant to most antibiotics except vancomycin and teicoplanin. Thegrowths in four cases subsided within 72 h with daily dressing, using an injectable soluCon of either vancomycin or teicophnin, while the rest required radical excision and immediale cover with split skin grafts and systemic administrafion of either of the antiobiotics. The wounds henled over a period of 8-70 days.

An effort to assess the level of seismic hazard in the region is, therefore, not only important but also imperative.

The fusion algorithms used are wavelet based fusion and Fuzzy Logic Approach (FLA) fusion. The FLA is presented as one of several possible methods for combining images from different sensors for achieving an image that displays more information than either image separately. Metrics are suggested that could rate the fidelity of the fused images, such as, an entropy metric.

Mobile robots can reach places, which are either inaccessible or unsafe for human beings. TACOM has developed a lab where new mobile robots can be tested. However to save cost and time it is advisable to test robots in a virtual environment before they are tested in a real Lab. The objective of this paper is to explore techniques whereby mobile robots can be tested in a simulated environment. Different techniques have been studied for such simulations and testing in a virtual environment. In particular, State flow and Zed3d software, VRML and Fuzzy Logic approaches have been exploited for this purpose. Different robots, obstacles and terrains have been simulated. It is hoped that such work will prove useful in the study of development and testing of mobile robots.

Image fusion provides output as a single image from a set of input images. The fusion should provide a human/machine perceivable result with more useful complete information. A great deal of interest has recently been shown in literature in image fusion because of its application in automotive, medical and other areas. Some techniques are currently available for image fusion. Some new approaches have been suggested in this work in particular, fuzzy and neuro-fuzzy. Algorithms are also proposed for the above said techniques for image fusion process. The work is also supplemented by algorithms, which help us analyze the output qualitatively on attributes like entropy, statistical moments, uniformity etc.
