Abstract: East Godavari district occupies a very important place in the fisheries map of Andhra Pradesh, which endowed with rich fishery resources of marine, inland and brackish water. The Ichthyofuan of East Godavari district was collected to record the biodiversity of fish fauna in the district. It is recorded that the fish fauna of this district comprises of 9 Orders, 59 Genera and 146 Species. The collection revealed that majority of the fish belong to other Cyprinoformes which predominates with 83 species followed by Siluriniformes with 30 species and Perciformes with 12 species. The Order Cypriniformes has most commercial importance fish such as Catla, Rohu, Mrigal and the common Carp. The Order Channiformes represents all murrels Channa striatus, Channa marulius, Channa gachua and Channa punctatus which are of great commercial value. Hilsa hilsa belongs to the Order Cluperformes is also recorded here, which is an anadromous migratory fish visiting River Godavari during early monsoon months. There is an immediate need to take measures to conserve this fish.

Keywords: Groundwater quality, Water quality index (WQI), Shivpuri town
Abstract: The present work is aimed at assessing the water quality index (WQI) for the groundwater of Shivpuri town. This has been determined by collected groundwater samples and subjecting them to a comprehensive physico-chemical analysis. For calculating the WQI, the following 12 parameters pH, TS, TDS, TSS, EC, total alkalinity, magnesium, calcium, total hardness, chloride, sulphate and nitrate were considered. The high value of WQI was found to be mainly due to higher values of iron, nitrate, total dissolved solids, hardness, fluorides, bicarbonate and manganese in the groundwater. The results of anlayses have been used to suggest models for predicting water quality. The anlaysis reveals that the groundwater of the area needs some degree of treatment before consumption, and it also needs to be protected from the perils of contamination.

Abstract: The particulate pollution has always been a matter of great concern because of its adverse effect on human and plant population. In the present global environmental scenario, this problem has become increasingly severe. The particulates and gaseous pollutants, alone and in combination, can cause serous setbacks to the overall physiology of plants. Results from numerous investigations of human respiratory and other diseases have shown a consistent statistical association between human exposures to the outdoor levels of particulates or dust and adverse health impacts. These hazards are more pronounced in the vicinity of industries where these particles become air-borne and inhalable. Research has shown that plant leaves being the main receptor of particulate pollution can act as biological filters, removing large quantities of particles from the urban atmosphere. This physical trait can be used to determine the level of particulate pollution in the surroundings, as well as the ability of individual plant species to intercept and mitigate particulate pollutants. In hte present study, fifteen plant species (11 trees and 4 shrubs) growing around the Rourkela Steel Plant (RSP) area were selected. Particulate or dust load on leaf surfaces and leaf surface morphology as a measure of dust trapping ability of leaves were analysed. The plant species such as Alstonia scholaris, Anthocephalus indicus, Cassia auriculata, Cassia siamea, Lagerstroemia speciosa, Mimusops elengi, Peltophorum inerme and Tabebuia aurea were found to have high dust capturing capacity; Albizia lebbeck, Bougainvillea spectabilis, Ficus religiosa, Sweitenia mahagoni and Thevetia nerifolia have medium, while species such as Caesalpinea pulcherima and Delonix regia have low dust capturing capacity. Results also indicate that leaf surface morphology greatly determines the dust trapping capacity of a particular plant species.

Abstract: The present experimental work was conducted to elucidate the haemato-biochemical studies in broiler chicks when treated with diclofenac sodium, ibuprofen and nimesulide. For this study 120 apparently healthy broiler chicks of either sex were randomly divided into 10 groups comprising 10 birds in 9 groups and 30 birds in control group. The broilers of diclofenac groups were administered 10, 20 and 30 mg/kg body weight of diclofenac sodium for 5 days. Similarly the broilers of ibuprofen groups were administered with 15, 30 and 45 mg/kg body weight of ibuprofen with feed for 5 days. The birds of nimesulide groups were administered with 10,20 and 30 mg/kg nimesulide for 5 days. The birds of control group were maintained on feed and plain water to serve as control. There was no significant difference in haematological parameters in birds which are intoxicated with diclofenac, ibuprofen and nimesulide. On the other hand there was significant difference in alkaline phosphatase and BUN biochemical parameters, but no significant difference in total protein and calcium intoxication in chicks.

Abstract: Present study is an attempt to understand the hydrochemical characteristics of groundwater in Amol-Ghaemshahr region, Mazandaran province in North Iran. Groundwater samples were randomly collected from 77 wells in Amol-Ghaemshahr plain having different depths, varying from 2.4m to 198m. The physico-chemical parameters such as pH, electrical conductivity (EC) and total dissolved solids (TDS) were measured in addition to majro cation and anion concentrations. The abundance of major ions is as follows: Ca2+>Na+>Mg2+>K+ and HCO3->Cl->SO42->NO3-. Thematic maps pertaining to pH, TDS, EC, Cl-, NO3-, SO42-and Na+ were presented in Geographical Information System (GIS) based maps. Different classes in thematic maps were categorized as desirable, permissible and unpermissible based on WHO standards for drinking purposes. The chemistry of water samples from coastal aquifer was interpreted by using classical Piper diagrams. The study indicates that Ca-Mg-HCO3 and Ca-Mg-Cl are the dominant hydrochemical facies followed by Na-Cl and Ca-Mg-SO4 facies. Gibb ' s plot reveals that the mechanisms responsible for controllling chemical composition of the groundwater are both rock-water interaction and evaporation.

Abstract: Rapid land use pattern change has taken place in Songhua River basin of old industry base in northeast region of China over the past decades in Harbin region. In this paper, changes in land use pattern in this region were analysed by using Landsat TM data in 1989 and 2007, to quantitatively explore the spatio-temporal LUCC (land use and cover change) characteristics, adn based on this information, the regional ecosystem service value was estimated. Cropland and unused land decreased, while built-up land increased greatly. The greatest change rate occurred in water bodies but the least occurred in cropland. The ecosystem service value increased 4.8490 x 108 yuan, with increasing range of 8.3285%, cropland turned into forestland occurred the greatest positive contribution rate, accounted for 18.9437%, while forestland turned into cropland occurred the greatest negative contribution rate, accounted for 10.2426%. The increase of built-up land impacted the ecosystem service value and ecological environment negatively, and the increase of forestland and water body and the decrease of unused land improved the ecological environment and its ecosystem service values. Those improving the ecological environment were from other types of land use to forestland and water body, however, those worsening the ecological environment were from forest and grassland to cropland and built-up land.

Abstract: Approximately 70-80% of the total energy used in villages is consumed for domestic cooking and 80-90% of the domestic energy needs are met through firewood, cow dung and agricultural crop wastes. The bio fuels are being burned in low efficiency traditional cook stoves. The environment within the house is polluted by the smoke emitted from the traditional cook stoves causing ill effect on health of women and children. To alleviate this problem, a number of double pot improved cook stoves (ICSs) have been developed for rural people. Experiments were conducted on different models of cook stoves viz. traditional cook stove, Sukhad, Udairaj and improved Udairaj models to find the thermal efficiency, power rating and specific fuel consumption by conducting water boiling test. Udairaj cook stove was found to have the highest thermal efficiency of 23.4%, whereas traditional cook stove was found to have lowest thermal efficiency of 15.4% among the cook stoves tested. Uadairaj and improved Udairaj cook stoves were found to have similar power rating and lowest specific fuel consumption in the range of 0.811 kw to 0.849 kw adn 1.232 kg/kwh to 1.225 kg/kwh respectively whereas traditional cook stove was found to have lowest power rating of 0.559 kw and highest specific fuel consumption of 1.799 kg/kwh.

Abstract: Removal of heavy metals from mine tailing effluent has been a long-standing environmental management issue in mining industry. In this study, removal of Mo(VI) from aqueous solutions was investigated using pyrite and cinder. Various parameters such as pH, agitation time and Mo(VI) concentration have been studied in batch experiments for the two materials firstly. The maximum adsorption of Mo(VI) occurred at pH 4.0 for cinder, and 3.0 for pyrite. Kinetic studies showed that Mo(VI) adsorption by the two materials generally obeyed a pseudo second-order model. Furthermore, application of Langmuir and Freundlich isotherm models to the adsorption equilibrium data showed that the adsorption behavior obeyed the Langmuir model. The adsorption capacity of cinder and pyrite was found to be 3.01 and 8.35 mg Mo(VI)/g adsorbent. Subsequently, three flow-through columns (Column 1#, Vpyrite: Vcinder = 2:1; Column 2#, Vpyrite: Vcinder = 1:1; Column 3#, Vpyrite: Vcinder = 1:2) were operated for the removal of Mo(VI) for six months. Results indicated the average removal efficiency of Mo(VI) by Column 1# were 47.68%, by Column 2# 50.03%, and by Column 3# were 23.34% respectively. Therefore, the pyrite-cinder mixture (Vpyrite: Vcinder = 1:1) proven to be a feasible adn cost-efficient treatment technology for Mo(VI) removal.

Abstract: A common complicationof diabetes is impaired wound healing. Systemic Rosmarinus officinalis oil improves healing in diabetics, which is dose dependent and may have side effects. There is very less information regarding topical Rosmarinus officinalis oil use. The objective of this study was to evaluate the effects of topical Rosmarinus officinalis oil on wound healing. Diabetes was induced in Wistar rats by using streptozotocin. The control group comprised age-matched animals not submitted to streptozotocin injection. Diabetic state was confirmed by glycosuria and hyperglycemia. Under tribromoethanol anaesthesia, four skin wounds (4 mm diameter) were performed on shaved dorsal area (2 each side of median line). Topical Rosmarinus officinalis oil was applied daily only on both wounds on right side of median nline. Animals were sacrificed on day 3 and 7 after surgery and tissue samples were prepared and observed under light microscopy. Histological, histometric and sterological methods were used for analysis. Topical Rosamrinus officinalis oil accelerated wound closure in diabetic and non- diabetic rats and the results were found to be more active than antibiotic treated controls. Topical Rosmarinus officinalis oil could be helpful in diabetics in order to improve the wound healing process avoiding possible adverse effects from systemic medication. All the values were statistically significant.

Abstract: Urban growth is most rapid in the developing world, where cities gain an average of five million residents every month in a year. The rapid urbanization and other infrastructre development in cities made workers to substitute a greater distance between their residencies and the ciites so it encroached industries and businesses to locate or relocate in suburban fringe areas which contain all facilities such as in metropolitan areas. The urban service area-Madurai, a metropolitan area, is currently experiencing linear to horizontal expansion and a variety of development pressures due to the unabated scattered population growth and socio-economic status, which portrays the conversion of agriculture lands, wet lands and number of water bodies into housing and industrial sites in a haphazard manner at the outskirts of the city known as Madurai suburban fringe area. This study evaluates the effectiveness of high-resolution satellite data and computer aided GIS techniques in assessing the land use change dynamics within the study area, Madurai city and its suburban fringe areas, from 2001 to 2008. Satellite images were used for the year 2001 and 2008 at scale 1:50000.

Abstract: Biosurfactants are surface active compounds which are produced by bacteria, fungi and yeasts. Most of them have different structures including: lipopeptides, glycolipids, polysaccharides, protein complexes, fatty acids and phospholipids. Nowadays, due to their useful properties, they have attracted attention of many. Therefore, the present study was conducted to isolate Gram positive bacteria capable of producing biosurfactants from Mighan Wetland in Iran. Accordingly, the isolated microorganisms were evaluated using oil spreading technique with different types of haemolysis tests. The selected microorganisms were detected by their ability to produce surfactants using TLC. The results indicated that out of seven different isolated genera two were characterized as Bacillus firmus and Staphylococcus sp. On the other hand, oil spreading technique indicated that organisms are able to produce biosurfactants. In addition, extracted biosurfactant on TLC plates and applying ninhydrin reagent indicated the lipopeptide structure of the biosurfactant by producing red spot. Hence, the present study illustrated that this area of investigation could be a suitable place for isolation of microorganism with capability to produce biosurfactants and it could be used for further study and applications.
