Zinc is a metallic element, of symbol Zn and atomic number 30, that is placed in the group 12 of the periodic table. As an essential trace element, zinc is required to support human biochemical processes. It is found in nearly 200 specific enzymes in the living organisms, and it also serves as structural cofactor for many cellular proteins. [1] Zinc may exert pleiotropic effects in organism; fo...

Within the last decade silicon has been recognized as participating in the normal metabolism of higher animals and as being an essential trace element. Silicon is found to perform an important role in connective tissue, especially in bone and cartilage. Bone and cartilage abnormalities are associated with a reduction in matrix components, resulting in the establishment of a requirement for sili...

The ErbB2 oncogene is often overexpressed in breast tumors and associated with poor clinical outcome. p130Cas represents a nodal scaffold protein regulating cell survival, migration, and proliferation in normal and pathological cells. The functional role of p130Cas in ErbB2-dependent breast tumorigenesis was assessed by its silencing in breast cancer cells derived from mouse mammary tumors over...

A solution to get the problem off, have you found it? Really? What kind of solution do you resolve the problem? From what sources? Well, there are so many questions that we utter every day. No matter how you will get the solution, it will mean better. You can take the reference from some books. And the promoting physiology as an essential element in translational research is one book that we re...

Among institutions of advanced legal systems, few have been more perplexing than the right to a fair trial. An important reason is its content, especially the relation of the institution to fairness or equity. The purpose of this paper is to provide, by correlating some well known episodes of legal philosophy that are usually kept apart, a new look at fairness of equity as an essential element ...

In 1931 eminent chemist Fritz Paneth maintained that the modern notion of ‘‘element’’ is closely related to (and as ‘‘metaphysical’’ as) the concept of element used by the ancients (e.g., Aristotle). On that basis, the element chlorine (properly so-called) is not the elementary substance dichlorine, but rather chlorine as it is in carbon tetrachloride. The fact that pure chemicals are called ‘‘...

Zinc (Zn) plays important roles in various biological activities but there is little available information regarding its functions in spermatogenesis. In our current study, we further examined the role of Zn during spermatogenesis in the Japanese eel (Anguilla japonica). Human CG (hCG) was injected into the animals to induce spermatogenesis, after which the concentration of Zn in the testis inc...

An element e of a 3–connected matroid M is essential if neither the deletion nor the contraction of e from M is 3–connected. Tutte’s 1966 Wheels and Whirls Theorem proves that the only 3–connected matroids in which every element is essential are the wheels and whirls. It was proved by Oxley and Wu that if a 3–connected matroid M has a non-essential element, then it has at least two such element...

The specific organizing the conditions of executing the job makes up the essential decisive about possibility obtainment element of competitive superiority. The ergonomic requirements are essential element of this process. They unite the environment of work with principles of the SCR, causing enlargement the man's part in development of enterprise.

To solve crack problems, some coupled methods have been developed in recent years. Most of these methods have some shortcomings such as the need for a transition region. The finite element and enriched element free Galerkin methods are widely used for this class of problems. In order to take the advantages of these methods while avoiding the disadvantages, it is essential to follow solution app...
