The experiment was conducted to study the damage assessment and effect of different neem products for the management of rice weevil (Sitophilus oryzae L.) in stored rice grain during the period from July to December 2013. Stored husked and unhusked rice of BR 27 were used as the experimental materials. The experiment consists of the treatments: T1: Neem leaves dust 10 gm/kg of stored rice grains; T2: Neem seed kernel dusts @ 10 gm/kg of stored rice grains; T3: Neem leaves extract @ 10 ml/kg of stored rice grains; T4: Neem oil 5 ml/kg of stored rice grains and T5: Untreated control. The experiment was laid out in the ambient condition of the laboratory following in a Completely Randomized Design (CRD). In case of unhusked rice, the highest mortality (100.00%) was observed in T4 treatment, while the lowest 5.25% mortality was recorded in T5 treatment. For husked rice, the highest mortality (100.00%) was observed in T4, while the lowest mortality (9.00%) was recorded in T5 treatment. At 1st generation for unhusked rice, in weight basis, the highest infestation was recorded from T5 (9.49%) treatment while the lowest in T4 (1.32) and for husked rice, the highest infestation was recorded from T5 (10.68%), while the lowest in T4 (2.79%) treatment. On the other hand, by number basis in unhusked rice, the highest infestation was found from T5 (11.57%), while the lowest in T4 (2.47%) treatment and for husked rice, the highest infestation was found from T5 (14.72%) while the lowest in T4 (3.86%) treatment. At 1st generation, for unhusked rice, the highest weight loss was found in T5 (18.21%), while the lowest was found in T4 (3.89%) treatment and for husked rice grain, the highest weight loss was recorded in T5 (21.45%), whereas the lowest was observed in T4 (4.38%) treatment. In case of repellency effect for unhusked rice, after 5 hours of treatment application the highest repellency rate was found from T4 and T3 (100.00%), whereas the lowest repellency rate (80.00%) was recorded in T1 treatment. In case of repellency effect for husked rice, after 5 hours of treatment application the highest repellency rate was found from T4 and T3 (100.00%) treatments which was followed by T1 and T2 (90.00%) treatments. Among the neem products neem oil 5 ml/kg of stored rice grains was more effective for controlling rice weevil. Key words: Rice, rice weevil, storage, neem product and management.

Anxiety is a psychological condition which changes the internal state of the body. During competition of games and sports the anxiety level is increased and might influence the performance of an athlete. The purpose of the study was to study the competition anxiety of National level basketball players and to find out the difference in competition anxiety level among the players played for different position. A total of 62 national level basketball players within the age of 15-19 years were selected randomly as subject for this study. Positional competition anxiety was studied by measuring the competition anxiety of players who played in different position and bear separate responsibility in basketball match. Competition anxiety level was the criterion measure in this study. Competition anxiety was measured by Illinois Competition Anxiety Test Questionnaire (1977) Mean and standard deviation was used as descriptive statistics and coefficient of correlation was calculated by product moment method. All calculations were done by the standard statistical procedure. Only 0.05 level of significance was considered for the present study. Result revealed higher anxiety level for defensive position basketball player than feeder position and offence position. Lowest was found for feeder position. However, the significance of difference of competition anxiety for different position player in basketball was calculated by ANOVA and result revealed that difference was not statistically significant. From above findings it was concluded that there was no significant difference in the competition anxiety for different position player in basketball. Key words: Basketball players, Competition anxiety, Position of play, National level.

Rock pools occur everywhere in the world and are geo-morphologically similar because they originated from weathering and erosion although vary in surface and depth. Interestingly, rare species are found as rock pool communities, which have never been recorded from open water. Temporary fresh water support invertebrate communities ranging from the complex, with many species to those that support only one or two species. The high variability in environmental condition connected with relatively unpredicted flooding regime limit for specialized species with high tolerance to stress and specific feature for surviving the dry phase. The differences in number of rocks and pools together with sampling intensity of individual pool may probably explain part of the variation in recorded diversity. Indeed, it is an established fact that the rock pools biotas are fully dependent on length and abundance of inundation and for that, the active communities will reflect the current climatic conditions. Temperature, Dissolved oxygen and pH are vital to the survival of many temporary water species as it provides essential indications that regulate the timing of life cycles, flight periodicities and colonization dynamics. Freshwater ecosystem served as an important asset for man and habitation for an extraordinary rich, endemic and sensitive species. Increase in human demand on these ecosystems results to large and rising threats to biodiversity and for that recording diminishes of biodiversity, identifying their causes, and finding solutions have become necessity in freshwater ecosystem. Keywords: Plankton, diversity, conservation and freshwater rock pools.

Leaching is one of the major unit operations used in mining sector. Leaching is extraction of the component from solids by using a solvent. The solvent preferably removes certain component. Leaching finds application in recovery of various valuable metals. Microbial leaching is gaining importance for recovery of metals from waste. It also plays important role in agriculture. It is always desirable to avoid the leaching of valuable components of soil through run offs. Various investigators have carried out research on various aspects of leaching. This review paper summarizes studies and research on various aspects of leaching. Key words: mining, bioleaching, recovery, metals, temperature, concentration.

Perhaps, no other single work of fiction has made such a momentous impact in Indian English Literature in recent years as Arundhati Roy’s The God of Small Things. She is one of the few Indian English writers actively interested in contemporary socio-political issues which are amply evidenced in a number of articles, interviews and books she wrote on various topics in recent years. The God of small things is about several themes - one of the chief issues it brings into focus is the family and social mechanism evolved over centuries in traditional Indian society to suppress woman and her independence as a human being. Key Words: Fiction, God of Small Things, Socio-political Issues.
