Aim: To study the effect of vaseetomy on histological appearance of the testis. Methods: Parkes strain mice wereused as the animal model; they were bilaterally vasectomized (Vx) or sham-operated (So) and killed at intervals of 4,6, 9, and 12 months after the operation. Testes were excised from 5 Vx and 5 So mice at each interval and processed for histological examination. Results: Testes of So mice showed normal histological features. By contrast, marked al-terations were observed in the seminiferou tubules in testes of Vx mice, except in those killed 4 months after the opera-tion. The seminiferous epithelium in the tubules was only 2-3 layers thick and showed much depletion of germ cells;in severe cases, the epithelium consisted of only a thin layer of Sertoli cells, spermatogonia and a few *** of germ cells, occurrence of multinucleated giant cells and vacuolated appearance of the epithelium were ofcommon features in the tubules. Furthermore, lumen of the rete testis in Vx mice was greatly dilated and showed accu-mulation of sermatozoa with immature germ cells; in mice vasectomized for 6-12 months, several macrophages in-gesting spermatozoa were ofte observed in the lumen of the rete testis. Spermatic granuloma was also somettimes no-ticed in corpus or in cauda regions of the epididymis in mice vasectomized for 6-12 months. Conclusion: We sug-gest that consequences of vasectomy should be thoroughly understood in order to make this method rather more popularas a reversible method of male contraception.

Projected changes in weather parameters, mainly temperature and rainfall, have already started to show their effect on agricultural production. To cope with the changing scenarios, adoption of appropriate management strategies is of paramount importance. A study was undertaken to evaluate the most appropriate combination of sowing date and phosphorus fertilization level for peanut crops grown in sandy loam soil in a subhumid region of eastern India. Field experiments were conducted during the summer seasons of 2012 and 2013 on peanut crops at the farm of the Indian Institute of Technology, Kharagpur. The DSSAT v4.5 CROPGRO-Peanut model was used to predict the phenology, growth, and yield of peanut crop under combinations of four sowing dates and four phosphorus fertilization levels. The model was calibrated with a 2012 dataset of growth, phenology, and yield parameters for estimating the genetic coefficients of cultivar TMV-2 and was validated with a 2013 dataset of the same parameters. Simulations of pod yield and other yield parameters using the calibrated model were found to be quite accurate. The model was able to reasonably simulate pod yield and final biomass with low normalized root mean square error (RMSE_n), low absolute root mean square error (RMSE_a) and high coefficient of determination (R^2> 0.7) over a wide range of sowing dates and different phosphorus fertilization levels sensitivity analysis indicated that sowing from the second week of January to the end of February with 30–50 kg P_2O_5 ha^(-1)would give the highest pod yield.

In this paper, an adaptive sampling strategy is presented for the generalized sampling-based motion plan- ner, generalized probabilistic roadmap （GPRM）. These planners are designed to account for stochastic map and model uncertainty and provide a feedback solution to the motion planning problem. Intelligently sampling in this framework can result in large speedups when compared to naive uniform sampling. By using the information of transition probabilities, encoded in these generalized planners, the proposed strategy biases sampling to improve the efficiency of sampling, and increase the overall success probability of GPRM. The strategy is used to solve the motion planning problem of a fully actuated point robot and a 3-DOF fixed-base manipulator on several maps of varying difficulty levels, and results show that the strategy helps solve the problem efficiently, while simultaneously increasing the success probability of the solution. Results also indicate that these rewards increase with an increase in map complexity.
