A. pruning old trees

Timber is a valuable source of wood. It is of high economic value. Large number of wood are cut to meet the needs of the wood. Pruning is a practice of selective removal of certain parts of the trees like branches, buds and roots. It is a method of timber renewal. The old trees with dead wood can be used for obtaining timber by pruning of dead branches prone with diseases, this will improve the quality of the wood, which can be used as a source of timber.

the transfer of energy between two molecules spaced just nanometers apart plays a key role in many technologies, including photovoltaics, quantum information systems, lighting, and sensors, as well as in biophysics to measure nanometer distances and in photosynthesis. but an open question in this area is what effect, if any, the surrounding photonic environment has on this nanoscale energy transfer. by designing and performing a carefully controlled experiment to answer this question, scientists have settled the debate and found clues to improving the efficiency of many of the technologies that rely on this process.
