Nacrtak The purpose of the study was to examine the ability of LiDAR (Light Detection and Ranging) to derive terrain slope over large areas and to use the derived slope data to model the effect of slope on the productivity of a self-levelling feller-buncher in order to predict its productivity for a wide range of slopes. The study was carried out for a self-levelling tracked feller-buncher in a...

Non-human primate populations, other than responding appropriately to naturally occurring challenges, also need to cope with anthropogenic factors such as environmental pollution, resource depletion, and habitat destruction. Populations and individuals are likely to show considerable variations in food extraction abilities, with some populations and individuals more efficient than others at exp...

concentrations of mn, cd, cr and pb were measured in soft tissues of p. radiata from the hendourabi and lavan islands. forty specimens were collected from each island from the depth 8-10 m using scuba. total, shell and soft tissues weights were measured. mn, cd, cr and pb concentrations of the soft tissues were measured using the atomic absorption technique. a significant difference between spe...

We study the Gauss-Bonnet (GB) term as the leading higher-curvature correction to pure Einstein gravity. Assuming a tree-level ultraviolet completion free of ghosts or tachyons, we prove that the GB term has a nonnegative coefficient in dimensions greater than 4. Our result follows from unitarity of the spectral representation for a general ultraviolet completion of the GB term.

Introduction: Duration of untreated periods (DUP) is one of the most important predictors of treatment outcome, prognosis of psychotic disorder. Also, most neuroimaging studies have investigated the gray matter changes and less attention has been paid to white matter. The object of this study is to focused on the microstructural integrity of more short DUP (<1000days) in a relatively large samp...
