The present paper discuss about the importance of teacher education and few suggestion about teacher education to make it in ore interesting and more comprehensive. The study indicates a strong association between teacher education and teaching efficiency of teachers. Again several factors have been found to be strong positive influence on efficiency of teachers. The study further revealed that 60% teachers strongly agree about the emphasis on B.Ed. Syllabus, where 40% teachers partially agreed i.e. more importance should be given to the method paper than in any other papers. Again in case of the improvement of teaching strategies, 70-80% teachers are strongly agreed where as 35-40% teachers are partially agreed. Only 50-55% teachers are strongly agreed against the formative evaluation process.Keywords

Mosquito-borne diseases are endemic in more than over 100 countries, causing mortality of nearly two million people every year. Present study deals with the negative impact of mosquito coil smoke on human being. It is also demonstrated that mesquites are susceptible to bite for Carbondioxide and lactic acid present in sweat in warm-blooded animals. The previous literature indicate that mosquito coil content very toxic ingradient such as pyrethrins which accounting for about 0.3 - 0.4 % of coil mass. The epidemiologic studies show that long term exposure to mosquito coil can induce asthma and persistent wheeze in children.

Over the last fifteen years, pharmaceuticals have been receiving increasing attention as potential bioactive chemicals in the environment. They are considered as emerging pollutants in water bodies. One of such pharmaceutical is paracetamol which show very difficult to remove from water. In this study, fixed-bed column experiments were performed to investigate the biosorption potential of paracetamol by low cost adsorbents egg shell and sugarcane. The adsorbents were characterized by using SEM, XRD and FTIR study. Present finding indicate that this particular pollutant easily removed by egg shell powder and sugar cane charcoal. Results suggest that, sugarcane charcoal is the best for paracetamol removal. The Thomas model data demonstrate that with increasing bed depth Thomas constant (Kth) increase linearly for egg shell, but sugarcane dose not showed such linearity with bed depth. The adsorbent exhaustion rate also showed linearity with bed depth as 3.2 cm (32), 7.5 cm (75) and 11.0 cm (110 ) for egg shell and 2.5 cm (50), 4.3 cm (86) and 6.2 cm (124) for sugarcane.Keywords
