In this article we investigate multiplicative effects between genes in relation to heterosis. The extensive literature on heterosis due to multiplicative effects between characters is reviewed, as is earlier work on the genetic description of heterosis. A two-locus diallelic model of arbitrary gene action is used to derive linear parameters for two multiplicative models. With multiplicative act...

one of the main concerns of intellectuals in the 40 and 50 th. back to the concept of self-concern in such abundance in the works of jalal ahmad, law, and nasr farid is there. however, in this context, one must ask: back to what self? in contrast, the return on the one hand, the rejection means and the other, a return to the past. however, such a return is guaranteed two assumptions: first, it ...

apermanent anti-graffiti clear polyurethane coating, using a silicone additive, was prepared and studied. various techniques, such as contact angle measurements and edx were employed to characterize and investigate thesurface properties of the coatings. the results revealed that with inclusion of silicon additive to clear coating, according to wu method, surface free energy was decreased from 4...

Although the processes of climate change are not completely understood, an important causal candidate is variation in total solar output. Reported cycles in various climate-proxy data show a tendency to emulate a fundamental harmonic sequence of a basic solar-cycle length (11 years) multiplied by 2(N) (where N equals a positive or negative integer). A simple additive model for total solar-outpu...
