This study estimates the earnings losses associated with workplace injuries that lead to permanent partial disability. Using unique administrative data from California, injured workers are matched to their co-workers with similar pre-injury earnings. Earnings loss is estimated as the difference in earnings between these two groups following injury. It is found that earnings losses are large. Mo...

due to the growing trend of rangelands degradation, study effects of different harvesting intensities on species in order to gain a more fundamental utilization of ranglands can be effective for reclamation and improvement. the purpose of this research was to study effects of different harvesting intensities on key species ajuga chamaecistus.this species has a forage value in the study area. in...

A simple, conceptual model for predicting forest productivity losses from soil compaction is presented. Information regarding each component of the model is summarized. Once compacted, most forest soils in the Pacific Northwest are expected to remain compacted and forest growth affected for several decades. Elements within the model which managers are able to manipulate to influence the amount ...

UNLABELLED The authors describe a convenient option for obtaining a columellar strut graft without the need for harvesting septal or auricular cartilage. Its utility has been shown by use in almost 10 percent of 569 patients in the senior author's (D.A.H.) series. CLINICAL QUESTION/LEVEL OF EVIDENCE Therapeutic, V.

introduction: broadcast fertilization method increases fertilizer losses while results in lower nutrient absorption by plant roots. fertigation is an effective method to increase water and fertilizer efficiency and to reduce the losses of nitrogen. moreover, it allows farmers to apply the nutrients in splits and few amounts in response to crop needs. in the present study, a field experiment was...

Piezoelectric vibration harvesters with strong electromechanical coupling coefficients have recently been combined nonlinear electrical techniques capable of tuning their resonant frequency as a solution to provide energy wireless sensor nodes from wideband vibrations. To be fully competitive, this approach requires piezoelectric generators global k2. However, the presence non-linear dielectric...
