Land use mapping is fundamental for assessment, managing and protection of natural resources of a region and the information on the existing land use is one of the prime pre-requisites for suggesting better use of terrain. Advances in satellite sensor and their analysis techniques are making remote sensing systems realistic and attractive for use in research and management of natural resources....
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
The low mountain forest area is known as a source of biodiversity because it has an with natural ecosystems that are relatively still intact and rich high level endemism. study was conducted to determine the found in forests under Kamojang. methods used qualitative quantitative data collection, vegetation collection using plot paths, fauna exploration (renaissance survey), edaphic climatic by p...
