This communication presents results pertaining to the adsorptive studies carried out on fluoride removal onto an algal biosorbent (Ulva fasciata). Batch sorption studies were performed and the results revealed that biosorbent demonstrated ability to adsorb the fluoride. Influence of varying conditions for removal of fluoride such as the fluoride concentration, the dosage of adsorbent, the size of adsorbent, and the concentration of metal solution was investigated. Experimental data showed good fit with the Langmuir's adsorption isotherm model. Maximum fluoride sorption was observed at 30°C operating temperature.Keywords

While surveying for raptors along the Achara beach in Malvan taluk of Sindhudurg district, Maharashtra, seahorses Hippocampus kuda belonging to the family Syngnathidae were noticed on the beach on 23 June 2015. All seahorses belong to one genus Hippocampus, in which there are 34 species recognized all over the world. Despite their small size, seahorses form a valuable fisheries resource in some areas and support a sizeable international trade. Hence all Hippocampus species are listed under Appendix II of the CITES and are categorized as vulnerable in the IUCN 2015 Red List of species.Full Text

Mental Health is the ability to balance feelings, desires, ambitions and ideas m one's daily living situations. It is the ability to face and accept the realities of life. The present study aims at assessing the mental health status of men and women of two different age groups(i.e., 30-39 yrs and 40-49 yrs) working m Govt., and private schools. The major objectives of the study are(i)To assess the mental health status of male and female teachers;(ii)To assess the mental health status of two different age groups and (hi) To assess the differences m the mental health of teachers working m Govt., and private schools. Mental Health Inventory developed by Jagdish and Srivastava (1983) was administered to 60 men and 60 women. Data was analysed using appropriate statistical techniques to assess the differences related to type of institute, gender and age with regard to the Mental Health of teachers.Keywords

The continuous consumption of groundwater carrying high amount of fluoride causes dental and skeletal fluorosis to humans. Excessive fluoride concentrations in groundwater have been reported in 25 nations including India where 14 states are facing fluoride problem. In view of this, an attempt has been made to find out the fluoride content in the groundwater and impact on the people. Nuzendla mandal, Guntur district is the present study area which is identified as one of the drought prone and fluoride incidence mandals of Andhra Pradesh. Groundwater samples from different hydro-geological set-up have been collected during pre- and post-monsoon seasons and determined for various physico-chemical parameters. About 62% and 68% of the samples collected respectively during pre-and post-monsoon seasons are exceeding the safe limit of 1.5 Mg/L of Fluoride. The chemical data of the groundwater shows positive correlation between F- & pH; F- & Na+; F- & HCO3- whereas negative correlation is observed between F- & Mg2+; F- & Ca2+. Probable sources of fluoride are weathering and leaching of fluoride bearing minerals under the alkaline environment along with high rate of evaporation and longer residence time of water. Correlation matrix also supports the above observations.Keywords
