India is among 23 nations where in a large population suffers from dental and skeletal flourosis due to high fluoride concentration in ground water. The prominent states, which are severely affected, are Andhrapradesh, Rajasthan, Gujarat, Uttar Pradesh and Tamil Nadu. Fluoride beyond desirable amounts (0.6 to 1.5 mg/l) in ground water is a major problem in many parts of the world. Taking the severity of the problem into consideration, the present study is carried out to study on effective and cheap adsorbents for the removal of fluoride from the water. Batch adsorption studies are carried out. Batch adsorption studies demonstrate that the adsorbents have the significant capacity to adsorb the Fluoride from water. The experiments were carried out in laboratory on certain low cost adsorbents like concrete, ragi seed powder, Red soil, horse gram seed powder, orange peel powder, chalk powder, pineapple peel powder and multhani matti.

A cordial labeling as an application of communication network, in this paper we have given cordial labeling for the graph Cp•Cq t ∀ p, q and t, i.e., attaching the one vertex union of cycles Cq on each vertex of cycle Cp, and also shown that the cordial labeling for the quadrilateral snake graph QSn, ∀ n gluing with each vertex of graphs Cp • Cq t, i.e., QSn (Cp • Cq t ), ∀ n ≥0. Finally the domination number of this graph is analyzed. © International Science Press.

The present paper deals with the effect of fertilizers i. e. (biological and chemical fertilizers) on the industrially polluted soils collected from the industrial regions of Hyderabad. The soils were collected from the industrial areas of Bolllaram, Patenchervu and Jeedimetla during winter season. The heavy metal content in the soils was determined by DTPA extraction method. It was found that Zn, Cu, Mg and Cd content of these areas was very high in these regions. Potassium content of these areas was very high, whereas nitrogen and phosphorus content of these areas was very low.the present study, the germination of seeds was carried out in the industrial area samples by applying chemical fertilizer urea and biofertilizer vermicompost. It was found that the germination started after 60 h in an untreated sample and when the soil sample was treated with the biofertilizer vermicompost, sprouting started after 50 h. The growth rate was very less compared to the treated samples with vermicompost. But no germination was observed in all three samples when they were treated with the urea.

Plants produce certain bioactive compounds which are naturally toxic to microorganisms and so have been investigated as therapeutic agents. The present study was carried out so as to evaluate the antimicrobial effect of essential oils of few aromatic medicinal plants namely, Lemongrass, Pongamia, Ocimum and Sandalwood. In vitro evaluation was done for individual oils as well as a combination of the oils, two at a time, in 1:1 ratio against bacterial pathogens. Test cultures used were namely Staphylococcus aureus, Pseudomonas aeruginosa and E. coli. The synergistic action was tested that is the combination formula with two assumptions, one that individual oil may show ineffectiveness if used repeatedly as seen in antibiotics and second the combined formulation may show the wider range of antimicrobial activity. In vitro assay was also carried out using commonly used antibiotics against these pathogens and compared with the synergistic effect of herbal extracts. The study showed promising results for the use of Lemongrass, Pongamia, Ocimum and Sandalwood in specific combination against sepsis causing Staphylococcus aureus, Pseudomonas aeruginosa as well as leading nosocomial agent E. coli.
