  Abstract Mapping and monitoring of forest area suffering from deforestation and forest degradation using satellite images and remote sensing has been an achievable activity for the sustainable forest management and conservation. Mapping of disturbance and degradation of forest is gaining momentum through Remote Sensing despite, major challenges still exist. The present study was conducted to quantify the forest area of deforestation and degradation within the Maya Devi collaborative forest of Terai region located at Kapilvastu district of Nepal. This study based on the optical satellite data (Landsat 7 ETM of 2000 and Landsat 8 OLI/TIRS of 2016) and spectral un-mixing of these datasets which produced fractional cover (proportion of vegetation, non-photosynthetic vegetation and bare soil). Under the environment of CLASlite tools, mapping of damaged canopy, exposed soil and dead vegetation were produced. With the gap of 15 years two Landsat Image of 2000 and 2016 we...

  Abstract It is well established that Orange peeled oil biodiesel (OPOB) is a suitable fuel in Compression Ignition (CI) engines because of its compatible physicochemical properties with diesel. Literature is however sparse on its emission characteristics in CI engines majorly because few investigations have been done due to seemingly difficult and time-consuming experiments. On this strength, this work first carried out experimental investigations on carbon monoxide (CO), unburned hydrocarbon (UHC), oxides of nitrogen (NOX) and smoke of orange peel oil based biodiesel in single cylinder, four stroke CI engine; and afterwards applied the power of artificial neural networks (ANNs) prediction model to predict to the full-scale CO, UHC, NOX, and SMOKE values of the CI engine. Brake load, orange oil-diesel mixture percentages and engine speed were the inputs of the ANN while Levenberg Marquardt (trainlm) and scaled conjugate gradient (trainscg) were the training algor...

  Abstract Water is so essential for living organisms that it is said “ save water, save life ”. Pollution of water, scarcity of water (drought), excess of water (flood) and excessive snow-fall are the different forms in which water becomes unusable/creates problems for the survival of many organisms. Therefore, saving water in its usable form is essential for the existence of life on the earth. One of the ways to save water is its judicial use, which is essential for increasing water productivity. Availability of water in sufficient amount, for those who require it, is necessary for ecological integrity as well as ecological efficiency. While ecological efficiency is related with resource utilization and the extent to which resources are converted into biomass, ecological integrity is crucial for biodiversity conservation. About two-third of the available fresh water is utilized for agricultural activities, and any imprudent/imbalanced use of water in agriculture w...
