Different transition metals (Mo, Cu, Mn,Ce, V, Co,Zr) supported on WTi-pillared clay were characterized by different techniques and tested in the selective catalytic reduction of nitrogen oxide by ammonia. The effects of diverse transition metals on the textural parameters, the acidity and the redox propertieswerecompared to, then correlated with the catalytic activities. The results demonstrate that the surface propertiesof the investigated materials are largely dependenton the type of transition metal added to the support.

The VanillaplanifoliaAndrews plants is a plantation commodity with high economic value and stablemarket price and is one of the quite valuable export commodities which can increase a farmer’s income and the State’s finances.

This study is about the determination of the extent of implementation of environment related aspects in terms of the University of Eastern Philippines’s personnel and purchasing policies; environment-friendly operations and presence of environmental programs on purchasing, water utilization and conservation, office machines and equipment use, canteen operation, general waste management and air quality. It made use of the descriptive correlation research design using frequency counts, weighted means.

This research aimed to analyse the right concentration of auxin, with composition of top soil planting media, cow manure and rice husk combined to the growth of pippernigrum. Pepper growers in the Laulara only use media land without adding manure (If j using the size without obvious) or ZPT (a regulator of plant substances) in the process of breeding that resulted in the growth of the plant is less good because even though the leaves are already quite a lot but haven't grown roots perfect (weak rooting), so when the opportunity to grow up in is very low.

Coconut water consumption on the edge of São Luís-MA has had a huge growth, justified by the number of bathers who frequent the beaches during the day or even by the practitioners of physical activities in the period of the night, calling attention to the conditions hygienic-sanitary that such food is marketed. This study aimed to assess the microbiological quality of coconut water and instruments used in the drilling of the fruit.

Present paper deals with the study of physico- chemical parameters of river, rural and urban ponds of Raipur district during the summer season for period of March 2017 to June 2017. Study of physical and chemical parameters such as temperature, transparency, pH (6.5-8.5), Free carbon dioxide, dissolved oxygen (5.2-7.5mg/l), Total hardness (68-190mg/l) and alkalinity are investigated. All parameters were under permissible limits. All selected water bodies are suitable for fish culture.

Plastic is a kind of material that is commonly well known and used in everyday life in many forms. Plastic pollution where in plastic has gathered in an area and has begun to negatively impact the natural environment and create problems for plants, wildlife and even human population. Often this includes killing plant life and posing dangers to local animals. Plastics contain many chemical and hazardous substances such as Bisphenol A (BPA), thalates, antiminitroxide, brominated flame retardants, and poly- fluorinated chemicals etc.

The Belo Monte Hydroelectric Power Plant is the most controversial construction in Brazil, due to the great environmental and social impact for the population living in its area of influence. Despite the requirements for the entrepreneur to execute the Basic Environmental Plan and the health determinants, which are aligned with local public policies, so far the impacts have not been adequately mitigated.

Health care institutions are generating large amount of Bio-medical waste (BMW), which needs to be properly segregated and treated. Hospitals and other health care facilities generate lots of waste which can transmit infections, particularly HIV, Hepatitis B and C and Tetanus, to the people who handle it or come in contact with it.

The alleviative effect of salicylic acid (SA) on growth and physiological parameters of two wheat verities under salt stress was studied at greenhouse condition in 2016. The experimental treatments were arranged as factorial based on a RCBD with 4 replications. Salinity stress comprised of three levels of control, 4 and 8 dS/m and the salicylic acid treatments were control (without salicylic acid) and 1 mM salicylic acid application. The experiment was carried out on two varieties of wheat (Tabasi, salinity sensitive and Arvand, salinity tolerant).
