Abstract: Floral and faunal diversity are the golden ornament of the ecosystem. Biodiversity is attracting the attention of many workers exploring the flora and fauna of different habitat of the world. Increased pace of development is reversing the physical, chemical, biological and ecological quality of environment. Faunal richness is one of the best indicators of the health of the habitat and ecosystem. Stress on environment is increasing continuously resulting natural habitat and ecosystem never get adequate time to recover its normal community structure. Now it is great challenge to protect diversity in their natural habitat. Raigarh district is blessed with plentiful natural resources in the form of forest, rivers, reservoirs, ponds, tanks, lakes, coal, dolomite, minerals attracting the industrialist for establishment of industries. Rapid industrialization in forest area, on the vicinity of the river, reservoir and the consequent effluent, sewage, discharge adversely affecting the natural aquatic ecosystem. Emission of industrial smoke regularly adding the pollutants in air and surrounding, adversely effecting the forest.....

Keywords – Avian biodiversity, Raigarh

Abstract: The present study aimed at identifying culturable bacteria(Bio-Aerosol) which are associated with particulate matter of the size 2.5 microns and less, by analyzing PM2.5 ambient air samples of quartz filter paper using classical culture techniques. The sampling was conducted in various areas of Delhi in both summer and winter seasons. Samples taken from the filters were placed in tubes containing nutritive broth BHI (Brain Heart Infusion) and incubated at 37 ˚C for 18 to 24 hours. This was followed by spread plating of appropriate dilutions of inoculums onto the surfaces of trypticase soy-agar (TSA).The results indicated a predominance of Gram positive, rod shaped, catalase positive bacteria associated with PM2.5 for both seasons. There was a predominance of endospores....

Abstract: Fruit juices becoming an essential part of the modern diet in many communities. Fruit juices contain nutrients as minerals, trace elements, vitamins and phytochemicals antioxidant. Fruit juices are nourishing beverages, in a healthy diet can play a major part because a variety of nutrients found naturally in fruits, also offer good taste in natural concentrations or processed forms. Fruit juices are available in any place in the world are available in bottles, cans, laminated paper packs, pouches, cups and almost every other form of packaging in diet of most people, irrespective of age included significantly thus, it contributes to good health. This study explored the heavy metals contamination of 15 samples of canned fruit juices collected from Benghazi markets......

Abstract: The cost-effectiveness and characteristic properties of nanoparticles have enabled the field of nanotechnology to gain traction in the past few decades. Silver nanoparticles (AgNPs), in particular, have found application across fields, in medicine, cosmetics, and other consumer products. AgNPs are antimicrobials, and while this property has enabled them to replace traditional bactericides on the market, it is also a point of concern when thinking about the disposal and accumulation of these nanoparticles in the environment. In past studies, AgNPs have proven to be biotoxic to phytoplankton- the marine algae that form the base of the aquatic trophic food chain and drive the global carbon and nutrient cycles. The mechanisms of AgNP ecotoxicology are up for debate......

Abstract: The present study was carried out to preserve the jackfruit slices through osmotic dehydration techniques. Fully ripe jackfruit of Khaja cultivar was collected from the farmer's orchard of Gazipur and then peeled and cut longitudinally to separate the bulb. For this study five different concentration of sugar solution (30, 40, 50, 60 and 70oBrix) were used to squeeze out water from the jackfruit slices followed by drying in mechanical dryer. Results revealed that moisture content of osmotically dehydrated jackfruit slices increased slightly from the initial 5.87-7.42% to final 8.06-9.44% after 6th month of storage. The ash content was recorded by dehydrated jackfruit slices prepared using 30oBrix (1.28%) sugar solution. Results also showed that the acidity was increased throughout the storage period in all samples.........

Abstract: The influence of oceans on the continental climate does not need to discuss.
The melting the Arctic and the Antarctic ice are lowering temperatures of the surrounding oceans.
Results are extreme differences between the temperatures of cyclones and anticyclones.
How the July and August isotherms of the coastal areas of Iceland, Greenland, Norway and Russia, and the east's coasts of the North America, are ranging between 5,0 and 10, 0, and more degrees of Celsius, lowering their temperature, due to the melting of the Arctic ice, can cause, lowering their temperature to the freezing point of the 0 degrees of Celsius, the first in the most Easter's coasts of Siberia.
