A multi-factor model for the grain yield prediction based on the previous data and relevant impacting factors is reported. In this model, the weight coefficient of each individual factor that affected the grain yield historically is analyzed by the variation coefficient method and the conversion degree function in the attribute theory. The effects of various factors on the predicted grain yield...
Addition of random phase to the object light is required in computer-generated holograms (CGHs) to widely diffuse the object light and to avoid its concentration on the CGH; however, this addition causes considerable speckle noise in the reconstructed image. For improving the speckle noise problem, techniques such as iterative phase retrieval algorithms and multi-random phase method are used; h...
We derive a model in which a standard international capital asset pricing model (ICAPM) is nested within an ICAPM with market imperfections. In the latter model an idiosyncratic stochastic factor affects the return of risky government bonds (over a risk-free rate) on top of the systematic component that is common to all countries (and that is interacted with a time-varying idiosyncratic “beta”)...
The objective of this study was to assess the bioaccumulation of heavy metals (Cd, Pb, Cr and Fe) in the muscles of five fish species (Sander lucioperca, Liza auratus, Alosa caspia, Cyprinus carpio and Liza saliens) from Gorgan Bay in the south-eastern Caspian Sea, in order to determine the value daily intake of heavy metals by consumption of fish and human health risk assessment. The concentra...
although on the basis of geo-economic theories, study of energy-related issues is of strategic importance to all countries, energy resources are no more restricted to oil and gas reserves as was the case during the past century. of course, these resources are still key elements of global energy reserves. today, in addition to geo-politics and geo-economics, the concept of hydro-geopolitics puts...
This paper reports the results of a 3-week drinking experiment in 51 healthy male subjects, examining the value of %CDT (carbohydrate-deficient transferrin) in the context of different levels of alcohol intake. All healthy persons were urine-tested drug-free and underwent daily breath alcohol tests for the 7 days preceding, and during the whole 3 weeks of, the experiment. Subjects were divided ...
