Wear is the most important problem of moldboard plowshares. Because of cutting the soil, intensity of wear at the front portion of share is large and the effect of its wear on plow performance is considerable. In this research wear of the front portion of moldboard plowshares with respect to distance worked was studied. Wear of cylindrical specimens which were attached to the front portion of ...

Silver K edge extended X-ray absorption fine structure (EXAFS) spectroscopy of films containing silver behenate (AgBeh) in the unprocessed, fully processed, and step-processed states has been performed. The results of the EXAFS analysis indicate that the intensity for the real-space peak for the Ag-O distance (~2.3 Å) decreases while the real-space peak for the AgAg distance (~2.9 Å) grows with...
PURPOSE To assess and evaluate the usefulness of 7 morphological measurements of the acetabulum in establishing the prevalence of acetabular dysplasia in the Singaporean population. METHODS Standardised plain anteroposterior radiographs of 522 hip joints of 261 asymptomatic patients (mean age, 60 years; range, 16-99 years) were evaluated. The 7 morphological measurements were centre-edge angl...
Forest edges can strongly affect avian nest success by altering nest predation rates, but this relationship is inconsistent and context dependent. There is a need for researchers to improve the predictability of edge effects on nest predation rates by examining the mechanisms driving their occurrence and variability. In this study, we examined how the capture rates of ship rats, an invasive nes...
Forest edges affect many aspects of plant communities, causing changes in microclimate, species composition, and community structure. However, the direct role of edges in regulating forest regeneration is relatively unknown. The pattern of tree establishment across a forest-old field edge was experimentally examined to determine the response of three tree species to the edge gradient. We placed...
