A STUDY OF MANAGEMENTAL PRACTICES IN WATER BUFFALO (BUBALUS BUBALIS) IN INDIA

ABSTRACT Comparative evaluation of farmers of rural and urban areas of Indore district of Madhya Pradesh, India was undertaken in terms of various managemental practices followed on the basis of herd size among different classes of farmers, and their housing, feeding, breeding and health coverage practices in buffaloes. In rural areas, a significantly higher number (59.33%) of farmers had mud houses with mud floors, whereas in urban areas, 68% farmers had Kiln-dried brick houses with concrete floors. In rural areas, the space available per animal was adequate in all cases but in urban areas, 68% of the respondents had inadequate space per animal. Feeding of green fodder throughout year in both rural and urban areas was practiced. A significantly higher number (88%) of urban farmers offered balanced ration to their animals as compared to rural farmers. In rural areas, only 9.66% of the farmers bred their animals with A.I., and 90.33% preferred natural service. More urban farmers followed cross breeding and grading up as breed improvement practices as compared to rural farmers. The analysis revealed that the rural buffalo gives less profit in comparison to those in urban areas due to lack of scientific animal husbandry practice and the low price of milk in addition to poor fluid milk marketing

Approximate Multiplier based on Low power and reduced latency with Modified LSB design

The devised approximation multiplier can adapt the precision and processing power needed formul triplication sat run-time based on the needs of the user. To decrease error distance, we also suggest a straight forward error compensation circuit. There are two types of approximate multi pliers. Dynamic voltages caling can be used for the first kind, which controls the timing route of the multiplier. If the voltage is lower, the critical path will take longer to complete. As a result, when the time path is violated, errors occurs and approximated results are produced. These cond types involves redesigning precise multiplier circuits like the Wallace Tree Multiplier and Dadda Tree Multiplier in order to change the functional behaviors of multipliers. Most of the earlier research on rebuilding multipliers suggested erroneous m-n compressors, which have m inputs and producen outputs. It dynamically reduces the area covered under the multiplier LSB which enables the MSB in accurate manner and LSB in approximate manner. This convolution al system approach is regarded to sequential cover up more than 32 bit multiplier. Since the accompanied circuit reduce then tire area by10times lesser than original multiplier, this conventional unit is regarded as abled circuit in the segment. Since the process of compressing partial products absorbed the majority of the multiplier energy and resulted in a consider able route delay, these incorrect compressors were utilized to compress the partial products within multiplication. These functionality are over come through our experimental setup

Effect of temperature anisotropy on various modes and instabilities for a magnetized non-relativistic bi-Maxwellian plasma

Using kinetic theory for homogeneous collisionless magnetized plasmas, we present an extended review of the plasma waves and instabilities and discuss the anisotropic response of generalized relativistic dielectric tensor and Onsager symmetry properties for arbitrary distribution functions. In general, we observe that for such plasmas only those electromagnetic modes whose magnetic field perturbations are perpendicular to the ambient magneticeld, i.e.,B1 \perp B0, are effected by the anisotropy. However, in oblique propagation all modes do show such anisotropic effects. Considering the non-relativistic bi-Maxwellian distribution and studying the relevant components of the general dielectric tensor under appropriate conditions, we derive the dispersion relations for various modes and instabilities. We show that only the electromagnetic R- and L- waves, those derived from them and the O-mode are affected by thermal anisotropies, since they satisfy the required condition B1\perpB0. By contrast, the perpendicularly propagating X-mode and the modes derived from it (the pure transverse X-mode and Bernstein mode) show no such effect. In general, we note that the thermal anisotropy modifies the parallel propagating modes via the parallel acoustic effect, while it modifies the perpendicular propagating modes via the Larmor-radius effect. In oblique propagation for kinetic Alfven waves, the thermal anisotropy affects the kinetic regime more than it affects the inertial regime. The generalized fast mode exhibits two distinct acoustic effects, one in the direction parallel to the ambient magnetic field and the other in the direction perpendicular to it. In the fast-mode instability, the magneto-sonic wave causes suppression of the firehose instability. We discuss all these propagation characteristics and present graphic illustrations

Pharmacognostic Standardization, Physico- and Phytochemical Evaluation of Amaranthus Spinosus Linn. Root

Amaranthus spinosus Linn. (Amaranthaceae) is found throughout India. This tree species has been of interest to researchers because it is a medicinal plant employed in the Indian traditional system of medicine. Pharmacognostic standardization; physico-and phytochemical evaluation of the roots of Amaranthus spinosus was carried out, to determine its macro-and microscopical characters, and also some of its quantitative standards. Microscopical studies were done by using the trinocular microscope. Total ash, water-soluble ash, acid-insoluble ash, sulfated ash values, and alcohol-and water-soluble extractive values were determined for physico-chemical evaluations. A preliminary phytochemical screening was also done to detect different phytoconstituents. Microscopically, the root showed cork, cortex, stellar region, and calcium oxalate crystals. Powder microscopy showed anamalous secondary growth in between the xylem vessels and Calcium Oxalate crystals in the cortex region. Total ash was approximately three times more than acid insoluble and water soluble ash. The ethanol soluble extractive was approximately the same as the water soluble extractive. Thin Layer Chromatography (TLC) of the Petroleum-ether extract using Benzene : Ethyl acetate (6 : 1), showed six spots. In the chloroform extract, using Benzene : Ethyl acetate (4 : 1) nine spots were seen, and in the ethanol extract, using Chloroform: Methanol (93 : 7), only four spots were observed, using Iodine vapor as a viewing medium. Phytochemically, the root exhibited terpenes, alkaloids, glycosides, and sugars. These findings might be useful to supplement information with regard to its identification parameters, which are assumed significant in the way of acceptability of herbal drugs, in the present scenario, which lacks regulatory laws to control the quality of herbal drugs

TNFRSF1B +676 T>G polymorphism predicts survival of non-Small cell lung cancer patients treated with chemoradiotherapy

<p>Abstract</p> <p>Background</p> <p>The dysregulation of gene expression in the TNF-TNFR superfamily has been involved in various human cancers including non-small cell lung cancer (NSCLC). Furthermore, functional polymorphisms in <it>TNF-α </it>and <it>TNFRSF1B </it>genes that alter gene expression are likely to be associated with risk and clinical outcomes of cancers. However, few reported studies have investigated the association between potentially functional SNPs in both <it>TNF-α </it>and <it>TNFRSF1B </it>and prognosis of NSCLC patients treated with chemoradiotherapy.</p> <p>Methods</p> <p>We genotyped five potentially functional polymorphisms of <it>TNF-α </it>and <it>TNFRSF1B </it>genes [<it>TNF-α </it>-308 G>A (rs1800629) and -1031 T>C (rs1799964); <it>TNFRSF1B </it>+676 T>G (rs1061622), -1709A>T(rs652625) and +1663A>G (rs1061624)] in 225 NSCLC patients treated with chemoradiotherapy or radiotherapy alone. Kaplan-Meier survival analysis, log-rank tests and Cox proportional hazard models were used to evaluate associations between these variants and NSCLC overall survival (OS).</p> <p>Results</p> <p>We found that the <it>TNFRSF1B </it>+676 GG genotype was associated with a significantly better OS of NSCLC (GG <it>vs. </it>TT: adjusted HR = 0.38, 95% CI = 0.15-0.94; GG <it>vs. </it>GT/TT: adjusted HR = 0.35, 95% CI = 0.14-0.88). Further stepwise multivariate Cox regression analysis showed that the <it>TNFRSF1B </it>+676 GG was an independent prognosis predictor in this NSCLC cohort (GG <it>vs. </it>GT/TT: HR = 0.35, 95% CI = 0.14-0.85), in the presence of node status (N_2-3<it>vs. </it>N_0-1: HR = 1.60, 95% CI = 1.09-2.35) and tumor stage (T_3-4<it>vs. </it>T_0-2: HR = 1.48, 95% CI = 1.08-2.03).</p> <p>Conclusions</p> <p>Although the exact biological function for this SNP remains to be explored, our findings suggest a possible role of <it>TNFRSF1B </it>+676 T>G (rs1061622) in the prognosis of NSCLC. Further large and functional studies are needed to confirm our findings.</p
