Optimum selection of machining parameters and its cutting conditions plays a major role in increase of productivity and minimization of total machining time. A significant improvement in process may lead to increase the process efficiency and low cost of manufacturing. In this research, Spindle speed, Feed rate, Depth of cut and End relief angle is considered as an input parameter for facing the A22E Bimetal bearing material using M42 HSS tool material. A second order mathematical model is developed using Design of Experiments (DoE) of Response Surface Methodology (RSM) to predict machining time on bimetal bearing material using special Industrial type of CNC lathe. The Analysis of Variance (ANOVA) was used to study the performance characteristics in facing operation. The values of Prob>F less than 0.05 indicate model terms are significant. Design Expert software is used to analyze the direct and interaction effects of the machining parameter. The genetic algorithm (GA) is trained and tested using MATLAB 7.0. The GA recommends 1.169 seconds as the best minimum predicted machining time value. The confirmatory test shows the second order regression predicted values and experimental values were very close and good agreement.

The present study was undertaken to evaluate the antipsychotic activity of formulated levosulpride sustained release formulation was compared with marketed levosulpride sustained release formulation in experimental animal models. Male Wistar rats (180- 220 g) and Albino mice (25-30 g) were used for the study. The antipsychotic effect of the formulated levosulpride sustained release formulation was evaluated on locomotor activity on photoactometer and ketamine induced stereotypic behavior. Different groups of rats were fed orally with a specially prepared diet containing formulated levosulpride sustained release formulation was compared with marketed levosulpride sustained release formulation for 15 consecutive days. Further, the biochemical estimations were done by estimating brain dopamine levels. The formulated levosulpride sustained release formulation significantly decreased the locomotor activity of rats. The formulated levosulpride sustained release formulation significantly decreased ketamine (50 mg/kg, i.p.) induced stereotyped behavior in a dose dependent manner. Formulated levosulpride sustained release formulation significantly decreased the brain dopamine levels. The results suggest that formulated levosulpride sustained release formulation posse's antipsychotic activity.Keywords

Odonata diversity in fish farm of Department of Fisheries, CSKHPKV, Palampur, Kangra Valley, Himachal Pradesh were comprehensively studied and documented for the first time. A total of 27 species belonging to 19 genera and 7 families of two suborders are recorded. The suborder Zygoptera was represented by 13 species and 14 species represents Anisoptera. Among the families, Libellulidae was richest family with 13 species and followed by Coenagrionidae with 9 species. The wide range of habitats including foraging and nocturnal roosting habitat at Fish Farm, CSKHPKV leads to greatest species diversity.Keywords

Background/Objectives: To study the seasonal changes influencing the various abiotic factors in estuaries and shallow coastal waters.
Methods/Statistical analysis: Water sample was collected from Uppanar estuary for a period of one year to analyze various physico-chemical parameters during the study period.
Findings: the present work was carried out on physic-chemical characteristics of water in Uppanar estuary, southeast coast of India during the study period. The findings of physical parameters are: water temperature values ranged from 24.0 to 32.0°C, salinity values of 15 ppt - 36.5ppt, pH values ranged from 8.3 – 7.4, turbidity range 1 to 2000 NTU, TSS (total suspended solid) from 1108mg/l - 1040 mg/l, and DO (dissolved oxygen) range 3.7 to 5.2 ml/l. Chemical parameters of water: NO2 ranged from 0.239 to 3.745 μM/l, NO3 values varied from 3.86 to 12.54 μM/l, TN (total nitrogen), ranged from 9.32 to 28.19 μM/l, IP (inorganic phosphate) values varied from 0.110 to 0.89 μM/l, TP concentration ranged from 1.19 to 32.62 μM/l.
Application/Improvements: The physical and chemical properties of water immensely influence the uses of a water body for the distribution and richness of biota and also influence both vertical and horizontal migration of aquatic organisms.

Background/Objectives: Macrobenthos are of special interest because of them are sessile or have a limited mobility and thus directly depend on environment conditions. They are showings marked response to environmental changes depending on their specific sensitivity and tolerance level. Among the macrobenthic forms, the polychaetes are dominant group which are important food source for higher trophic levels of most estuarine and near shore environment. Methods/Statistical Analysis: Sediment samples were collected from Uppanar estuary, Cuddalore coast for a period of one year from Jan’ 2011 – Dec’ 2011 to collect and analyze the distribution and diversity of polychaete species during the study period. Findings: The distribution and diversity of polychaete species, the total numbers of 36 species were recorded belonging to 19 families during the study period in this station. The maximum 32 species of polychaetes were recorded in summer and minimum of 23 species were recorded at monsoon. Among them five species of polychaetes (Capitella capitata, Nereis virens, Polydora ciliata, Perinereis cultrifera and Glycera Alba) were dominated in all the seasons. Application/Improvements: They are playing an important role in ecosystem process such as nutrient cycling, pollutant metabolism and dispersion. They are also considering as an important secondary production of among the macrobenthos. Polychaetes are also play a important role of pollution indicator.Keywords
