1.1. Brief overview. The theory of partial differential equations when one, or more variables, is in the complex domain, and approaches a characteristic variety has only recently started to develop. In their paper [11], generalized in [12], O. Costin and S. Tanveer proved existence and uniqueness of solutions with given initial conditions, for quasilinear systems of evolution equations in a lar...

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is a by-product o f t he trichlorophenol (herbicide) production and is also produced through a variety of combustion processes. It appears that TCDD is a ubiquitous chemical, particularly in industrialised countries, and the liver is the target organ of its toxicity. The prominent hepatotoxic effect of TCDD is progressive centrilobular necrosis. Th...

let r be a ring and v be a matrix valuation on r. it is shown that, there exists a correspondence between matrix valuations on r and some special subsets ?(mvpr) of the set of all square matrices over r, analogous to the correspondence between invariant valuation rings and abelian valuation functions on a division ring. furthermore, based on malcolmson’s localization, an alternative proof for t...

Introduction. Determining educational needs is the first step in educational planning. Need assessment influences all the decisions regarding educational content, objectives & effective use of resources. To determine the correspondence of educational needs & content in the psychiatry & pediatrics prevalent diseases workshops. Methods. To do this cross- sectional study, 50 physicians participat...

Intuitively, the more powerful a theory is, greater variety and quantity of ideas can be expressed through its formal language. Therefore, when comparing two theories concerning same subject, it seems only reasonable to compare expressive powers their languages. On condition that quantum mechanical description is universal so applied macroscopic systems, required than classical mechanics. This ...

This paper shows a study on design opportunities based assertive communication and social skills in children. Research with qualitative approach was conducted to know the of students their ability express themselves. On other hand, linear regression model carried out quantitatively determine percentage deficit at home variables that have an impact problem. In addition, bibliographic criteria we...
