there are different methods used for threshing of grain crops. usual threshers operate based on the impact force (in threshing unit) that may damage the grains. in another method named axial-flow, grain damage is less so these types of the harvesting machines are being used more than before. in this study one of the common rice threshers (model t30) locally made in ashtad company was modified t...
most impact tests are carried out on specimens with specific stacking sequence and dimensions to meet standard and experimental limitations. the damaged areas and the resulted reduction in the strength values of specimens may not agree very well with those of real application. in this paper an attempt is made to study the variation in the size of damaged areas due to varying the dimension of te...
Abstract: Companies with market power occasionally engage in intentional quality reduction of a portion of their output as a means of offering two qualities of goods for the purpose of price discrimination, even absent a cost saving. This paper provides an exact characterization in terms of marginal revenues of when such a strategy is profitable, which, remarkably, does not depend on the distri...
Summan Previous cross-sectional data suggest a positive association between serum cholesterol and brain neoplasms. but the results of cohort studies are inconclusive. There is evidence that in women the growth of meningiomas and astrocytomas depends on the hormonal status. The present investigation comprised data on serum cholesterol and P-lipoprotein concentration among 229 participants in a h...

This Report is enriched by the personal observations of the author who ran a Hostel at Windermere for boys coming from Belsen, Buchenwald and Auschwitz in July 1945 and afterwards worked under the Control Commission in Germany. She is, therefore, able to give living examples which illustrate the wisdom she has painfully acquired. Understanding of the children's problem and of the possibilities ...
A durable-goods monopolist may use quality degradation as a commitment not to lower price in the future. The introduction of damaged goods expedites lowvaluation consumers future demands, and helps the firm to mitigate the Coasian time-consistency problem. In such a case, damaged goods are more likely to be observed relative to the static setting where only the price-discrimination aspect of q...
Mediterranean stone pine nut is appreciated for its high economic and nutritional value. Starting in 2012, Pinus pinea production declined throughout the area. The dry cone syndrome associated with this decline introduction of Leptoglossus occidentalis occurred simultaneously. This study aims to evaluate potential reasons behind Lebanon, considering climatic factors invasion L. occidentalis. Co...
Feun Kase seed extract can be used as a corrosion inhibitor on zinc metal in HCl solution. This study aims to determine the secondary metabolites contained extract, inhibition efficiency and rate, surface morphology of process using media. was obtained by maceration extraction methanol. In test, concentration temperature variations were carried out effect rate per year. The results showed that ...
