Abstract: During dearth period, major drawbook in feeding and resulted colonies destroyed in commercial beekeeping. The temperature was recorded high 480C during this period, thus, it was very difficult to honey bees to collect food. The honey stores in farmes in a colony was maximum (3.44 and 2.96 kg/colony provided with artificial diet T4Whereas, the minimum (2.28 and 2.02 kg/colony) with artificial diet T1 in both years, 2009 and 2010, respectively. The finding revealed that when colonies were fed with T6 artificial diet, the colony performed better management of ApismelliferaL. Colonies during dearth period..

Abstract: Human population all kinds of vegetation and water for the life of fauna is a mandatory requirement. With the growing industrial sector of the science and increasing population growth, water crisis is becoming a major challenge before the world today. The present world population has more than 7 billion. The use of water in the water is increasing day by day. Water from the well, the tube well, is going down every year. It is decreasing at a speed of 2 to 6 meters in parts like Rajasthan. Today the ocean section is part of 70.78 percent of the world. But there is an odd distribution of them. In the northern hemisphere, there is a high degree of space. The continental part is also less in the Northern Hemisphere. These parts......

Abstract: Fishes serve as important bio-indicators for aquatic contamination to assess the changes caused by human activities effectively and reliable monitoring bio-system to recognize and predict hazardous effects of pollutants. As such exposure of pesticides induces physiological and behavioural alterations in the fishes. In present investigation, it was found that the quantity of Triazophos requires to constitute Lc50 dose for 24 hrs and 48 hrs duration of treatment was 38.0 mg/l and 26.8 mg/l respectively and for the sub lethal it was 16.180 mg/l. Besides, fishes exhibited following behavioural changes: restlessness rapid superficial movement of the fins and increased rate of opercular movements, sign of loss of equilibrium, secretion of large quantity of mucus and in the dying fishes, feeble opercular movement and expanded bronchial chamber was observed. All these behavioural changes in fish was dose and duration dependent.

Abstract: During the present study, phytoplanktons were represented by Cyanophyceae, Chlorophyceae and Bacillariophyceae from Makhana Pond of Darbhanga district. The Chlorophycae was rich in species Diversity being represented by 17-species followed by Cyanophyceae and Bacillariophycae with 6 and 5 species, respectively, in Makhana pond. The phytoplankton density was recorded highest during April 2008 and the lowest during December 2008. It exhibited trimodal pattern of fluctuations during the study period. Among the three peaks, two were in November 2008 and April 2009, and one minor peak in June 2009. In November 2008 it was recorded as 3637 U/L. But in December 2008 its density dropped suddenly to 989 U/L and after that the increase continued till April.....

Abstract: Mercury (Hg), arsenic (As), chromium (Cr), copper (Cu), Molybdenum (Mo), Selenium (Se) and Iron (Fe) were analyzed in drinking water, soils, vegetables, maize, human scalp hairs and nails samples collected in the low lying areas of Migori Gold Mining Belt within Lake Victoria basin and an agricultural region of Eldoret (control site). All samples, except water and soils, were washed with deionized water, dried and acid digested, and later analyzed using ICP-MS in Bueritas Labs, Vancouver, Canada. The results revealed elevated metal concentrations which could lead to a significant risk of exposure and a substantial increase of contaminants in the consumers of water and food.....

Abstract: Background: Human activities have instigated widespread pollution of the natural global environment. Recalcitrant wastes persist for long periods, are trans-boundary pollutants, travelling large distances from their point of origin in the environment and bioaccumulate in humans and other organism through the food chain. Therefore, environmental remediation is necessary for polluted land to produce safe crops and reduce environment risks. Biosurfactants increase the bioavailability of hydrocarbon resulting in enhanced growth and degradation of contaminants by hydrocarbon-degrading bacteria present in polluted soil. Hence, the presence of surfactants may increase microbial degradation of pollutants. In comparison to their chemically synthesized equivalents they have many advantages..

Abstract: Bangladesh is a well-dilating developing country in the South East Asia region. Although having a scarcity of composition, but susceptible enough to challenge any life-threatening diseases such as AIDS, cancer, hepatitis b-g, and more. Currently,the prominent obstacle is cancer with a huge variability, exposed as a combination of more than 100 types of diseases accompanied by uncontrolled growth and proliferation of an abnormal/mutated cell, ultimately leads to death. The tumour is the initiation of this and manifest as cancer when it sprouts to the distant body parts through metastasis. Although all tumours are not cancerous; only the malignant ones do so. According to the world health organization Africa, Asia, Central and South America is the most affected zone with 60% new cancer cases with 70% of total death (Ferlay et al., 2015). A report revealed that about 2, 00,000 people are affected by......

Abstract: Natural disasters like hurricanes, wildfire, earthquake, flood, tsunamis, and volcanic eruption often have catastrophic effects on human lives and cause significant infrastructure harm. It is challenging to detect these disasters as quickly as possible before it can largely affect human and animal lives. Remote sensing applications are used for this purpose. Images captured from the satellite are assessed to identify any abnormal change in the atmosphere, which may lead to a natural disaster. However, these systems are still not fully automatic and require human effort to analyze satellite images properly. Use of human resources for this purpose makes this process time-taking and also human error-prone. Recently, a wildfire in Amazon rainforest got the attention of the world when NASA released a satellite image of the burning forest. The forest could be saved if we can detect wildfire at an early stage and take appropriate action to minimize losses.Current advances in remote sensing applications yield significant success in the management of natural disasters. It still requires human effort and time....
