Abstract: The predatory potential of Bradinopyga geminata, Crocothemis servilia and Ceriagrion cerinorubellum larvae on Aedes aegypti larvae were recorded for 8 hours with three replicates under laboratory condition to suggest biocontrol methods to get away from the spread of dengue fever. The maximum consumption rate of Bradinopyga geminata was on 1st instar larvae of Aedes aegypti. Crocothemis servilia and Ceriagrion cerinorubellum shows maximum consumption rate on 2nd instar larvae of Aedes aegypti. With respect to the One-way ANOVA test conducted, Bradinopyga geminata shows highest predatory impact on all the instars of Aedes aegypti. The present study reveals that the release of odonata nymphs especially Bradinopyga geminata in areas of dengue epidemics will effectively control the Aedes aegypti larval production and thereby dengue epidemics.

Abstract: The medical facilities have initiated the development of healthy societies. Diseases that may have been called dangerous in the past have now not being feared and become easily treatable diseases. The development of medicine has also increased the amount, variety, and harm of medical wastes. Medical wastes, which are not properly managed, cause harm to the environment and human health. The medical waste management in Turkey as well as in the world is becoming a more and more remarkable subject. In this study, the medical waste inventory was created in a very difficult area in terms of topography. Artvin was selected as the study area in the region, and it was desired to represent a province which differs from the other provinces in terms of population and geography. The data used...........

Abstract: The aerobic biodegradation of benzene in laboratory cultures have been well studied, by using alkaliphilic bacteria strain Bacillus badius D1, The bacterial strain Bacillus badius D1 could complete degradation of benzene at a concentration of 5 ml/100 ml at pH 9.0 within 48 hrs, The metabolites of aerobic degradation of benzene by this strain were identified as Catechol, 2-hydroxymuconic semialdehyde and 2-hydroxypenta-2,4-dienoic acid. The structural determination of the intermediates of benzene degradation was carried out by spectroscopic analysis like GC-MS chromatography and FTIR spectra. A tentative pathway of benzene degradation is also reported. To our knowledge, this is the first report that the isolated bacterial culture of Bacillus badius D1can capable to degraded benzene under alkaline conditions.

Abstract: Tannery effluent is one of the most hazardous pollutants containing heavy metals, nutrients, toxic chemicals and others. Therefore identifying potentially efficient low-cost and locally available filter media as an adsorbent for the treatment of tannery wastewater is critical. In present study the efficiency of pumice (volcanic rock) investigated as a filter media for tannery wastewater treatment with selected physicochemical parameters. The volcanic rocks were collected from volcanic cones of refit valley area of Oromia region, Ethiopia and there chemical characteristics were determined using XRF analysis. Batch mode experimental study design has been carried out. The filter media pumice was crushed and graded and effective size was determined by using standard sieve. The composite sample wastewater was collected from Dire tannery, Addis Ababa Ethiopia. The physicochemical analysis of wastewater samples.........

Abstract: In the present era getting pure water for drinking is hard in most of the countries. Reverse osmosis and desalination are the two methods of purifying water. The current study uses the desalination process to purify water using evacuated glass tubes as the main tool to remove the water from contaminants in contrast with the other systems which uses the method of removing contaminants from water. The distillation technique takes the advantage of the principle that dissolved substances in water vaporize at different temperatures. Most potential chemical contaminants in water are having higher vaporization point than water. Measurement of Stagnation temperature plays an important role in..........

Abstract: Dragonflies and Damselflies, collectively called Odonates and are one of the most common insects flying over forests, fields, meadows, ponds and rivers. Few streams, ponds, marshes, swamps and hilly green areas with lesser disturbance of humans were selected for the present study. Transect method was employed for the present study. A line transect of 500m length was laid in ten selected study areas and the odonates observed along the transects were documented and photographed. The diversity and abundance of the documented species of dragonflies and damselflies were measured and the Shannon and Simpson's diversity indices were calculated using the standard formulae available. 52 species belonging to 28 genera and 10 families are documented in the present study. Out of these 29 are Anisopterans (Dragonflies) and remaining 23 are Zygopterans (Damselflies).

Abstract: The aim of present study was to evaluate the levels and spatio-temopral variation of Soil Organic Carbon (SOC) in different particle-size aggregates (bulk, coarse sand, fine sand and silt+clay) in the agricultural field of National Capital Region (NCR) in subtropical India. Soil samples were collected from peri-urban vegetable cultivation areas during three seasons of 2011-12. The conventional analytical method (Walkley Black) was used to estimate the SOC levels for all the particle-size aggregates. The results showed that the mean SOC in bulk samples was 10.97 mg g-1 while values for Fraction-I (Coarse sand), Fraction-II (Fine sand) and Fraction-III (silt + clay) were estimated to be 9.17±1.87 mg g-1, 12.61±3.08 mg g-1 and 18.04±3.81 mg g-1, respectively during overall studied period. Distinct seasonal differences have been noticed in the levels of SOC in bulk and fractional samples as highest in..........
