Experimental metastatic calcification in the proximal convoluted tubules of rat kidney, produced by large doses of vitamin D, has been studied with a variety of techniques. These techniques include the examination of thin sections of Araldite-embedded material under the electron microscope, selected area electron diffraction, and several histochemical methods. Two types of mineral are found in ...

central to vygotsky-inspired sociocultural theory (sct) is the notion of zpd seen by sla researchers as a useful framework within which l2 teaching and learning can take place. van lier (2004) argues that the zpd could be activated in diverse proximal contexts (pcs) and is not limited to the expert-novice scenario. . this study probed whether iranian efl learners' collaborative task performance...

This paper introduces a visibility relation v (and the strong visibility relation ⩕ v) on proximal Delaunay meshes. A main result in this paper is that the visibility relation v is equivalent to Wallman proximity. In addition, a Delaunay triangulation region endowed with the visibility relation v has a local Leader uniform topology.

statement of problem: dental caries is one of the common diseases in the world. it is an infective disease which is caused by loss of minerals and destruction of dental tissues. one of the most effective ways to diagnose the interproximal caries is radiography. bitewing radiography is the best way for caries diagnosis. purpose: the aim of this study was to evaluate the prevalence of the interpr...

An extension of the proximal minimization algorithm is considered where only some of the minimization variables appear in the quadratic proximal term. The resulting iterates are interpreted in terms of the iterates of the standard algorithm, and a uniform descent property is shown that holds independently of the proximal terms used. This property is used to give simple convergence proofs of par...

Standing notations. Let (X, T, ir) be a transformation group with compact phase space. The proximal relation of (X, T, if) is denoted by P(X) and the syndetically proximal relation by L(X). The product transformation group induced by (X, P, 7r):;will be denoted by (XXX, T, p), which is defined by (x, y)pi = (xirt, yir1) for (x, y) QXXX and tQ T. For simplicity we shall write xt for X7r' and (xt...
