We address the problem of determining physically correct definition momentum and angular densities in a spatially structured electromagnetic field, given that expressions are not same when one uses canonical energy-momentum tensor instead symmetric Belinfante electrodynamics. This has important consequences for interaction matter with light, example, twisted photons, would give drastically diff...

Information on the productivity, costs and applications of the logging system is a key component in the evaluation of management plans for the rehabilitation and utilization of Caspian forests. Skidding and road construction costs are expensive forest operations. Determining the optimum forest road network density is one of the most important factors in sustainable forest management. Logging me...

Progressive loss of bone mineral density around the femora! component of total hip replacement continues to pose a threat to long term prosthetic survival. A linear study was undertaken to measure bone mineral density on a monthly basis following total hip arthroplasty in 11 male patients. The opposite femur was used as the control measurement. Bone mineral density was unchanged at two mo...
