In 1989, a watershed acidification experiment was begun on the Fernow Experimental Forest in West Virginia, USA. Ammonium sulfate fertilizer (35.5 kg N ha yrand 40.5 kg S ha yr) was applied to a forested watershed (WS3) that supported a 20-year-old stand of eastern deciduous hardwoods. Additions of N and S are approximately twice the ambient deposition of nitrogen and sulfur in the adjacent mat...

Papaya (Carica papaya L.) is a crop of great economic importance. It the fourth most produced tropical fruit in world. The substantial problems faced during its production are pests and diseases, which why it has been planted under greenhouse conditions. However, required that plants not be height to need tall greenhouses. Therefore, this research aims evaluate salinity effect identify nutritiv...

Aquaponics is the integration of farming fish with plants where excreted nutrients from are taken up by plants. Thus, aquaponics may enhance aquaculture sustainability and productivity. In this study, largemouth bass Micropterus salmoides juveniles were cultured in a recirculating system (RAS) or aquaponic for two months. Each was identical, but within system, lemongrass spring onion without gr...

Water samples from municipal water supplies in Kathmandu District were collected 10 different sampling spots between April to May, 2018. Analyses of various physico-chemical parameters conducted. Physical (pH, electrical conductivity, TDS) and Chemical Parameters like (total alkalinity, total Hardness, calcium, magnesium, chloride, iron, nitrate, ammonia) determined. This analysis was undertake...

The effects of mixed gas annealing ambient of O2 and N2 on electrical and optical characteristics of p-type Mg-doped GaN grown by MOCVD were investigated at various annealing condition. A mixed gas ambient of 80% O2 and 20% N2 at 750°C for 2 minutes was found to be an optimum annealing condition with improvements on activation efficiency of Mg acceptor compared with annealing in pure O2 or N2 g...
