Understanding of common

This thesis deals with the finite element simulation of spot welded joint in crash analysis. Spot welding is a very common joining process in the automotive industry. It is cost effective and it provides a very fast production rate of automotive body components. Despite this advantage, spot welds are very susceptible to various types of loading conditions. Therefore they are prone to failure, if not designed properly, during their service life time. Therefore it is very important to understand the behaviour of spot welds and their failure characteristics.

The purpose of the study is to quantify breast dose to reassure patients and staff that these understandings still apply. A combination of measurements and simulations were used to estimate absorbed breast dose. Gafchromic® XR-QA2 film was used to measure breast dose placed inside the RANDO® phantom in a series of controlled experiments. The RANDO® is an anthropomorphic phantom commonly used for dosimetry investigations. Gafchromic® XR QA2 film is a radiochromic film that changes colour when irradiated. Simulation is commonly used and readily available.

The minor purpose of the study focuses on helping the first year English major students at Haiphong University of management and technology as well as myself to have a general understanding of errors in writing skill. The major aim is identifying the grammatical and lexical errors in details, their possible causes of making these errors and suggested solutions.

This study synthesizes the use of chemicals to prevent one of common concrete durability problems, alkali-silica reaction (ASR), and can help researchers (i) identify widely used potential chemicals and evaluate these chemical solutions to prevent ASR with proper understanding of mechanisms, and (ii) to identify the research gaps in order to develop guidelines and implementation plan on the use of these chemicals for future research.

Regulators of G protein signaling (RGS) proteins modulate G protein-coupled receptor (GPCR) signaling networks by terminating signals produced by active Gα subunits. RGS17, a member of the RZ subfamily of RGS proteins, is typically only expressed in appreciable amounts in the human central nervous system, but previous works have shown that RGS17 expression is selectively upregulated in a number of malignancies, including lung, breast, prostate, and hepatocellular carcinoma.

This thesis mainly aims to provide the English learners with a basic knowledge of stylistic devices used in political quotations to enable them to understand political quotation thoroughly. Moreover, it also encourages them to use the stylistic device in speaking and writing to make their speeches and written papers more beautiful and attractive.

The result of the study will be another illustration for the beauty of language, especially when it is used under the observation of cognitive semantics and metaphor. The findings of a contrastive analysis of English and Vietnamese will be a great benefit for Vietnamese learners of English. Moreover, the deep investigation will help them improve their understanding of meanings of words denoting the Names of human body parts and get better results in reading comprehension, translation work as well as in everyday language.

This chapter is an introduction to the application layer. In the next eight chapters we introduce common client-server applications used in the Internet. In this chapter, we give a general picture of how a client-server program is designed and give some simple codes of their implementation. The area of network programming is a very vast and complicated one; it cannot be covered in one chapter. We need to give a bird’s-eye view of this discipline to make the contents of the next eight chapters easier to understand.

HIV-1 protease (PR) and two drug-resistant variants – PR with the V82A mutation (PRV82A) and PR with the I84V mutation (PRI84V) – were studied using reduced peptide analogs of five natural cleavage sites (CA-p2, p2-NC, p6 pol -PR, p1-p6 and NC-p1) to understand the structural and kine-tic changes. The common drug-resistant mutations V82A and I84V alter residues forming the substrate-binding site. Eight crystal structures were refined at resolutions of 1.10–1.60 A ˚ .

Familial amyloidotic polyneuropathy (FAP) is an inherited autosomal dominant disease that is commonly caused by accumulation of deposits of transthyretin (TTR) amyloid around peripheral nerves. The only effective treatment for FAP is liver transplantation.

Mixed lineage leukemias (MLLs) are histone-methylating enzymes with critical roles in gene expression, epigenetics and cancer. Although MLLs are important gene regulators little is known about their own regulation. Herein, to understand the effects of toxic stress onMLLgene regulation, we treated human cells with a common food contaminant mycotoxin, deoxynivalenol (DON).

A combinatorial bijection between k-edge colored trees and colored Pr¨ufer codes for labelled trees is established. This bijection gives a simple combinatorial proof for the number k(n − 2)!nk−n n−2
of k-edge colored trees with n vertices.A k-edge colored tree is a labelled tree whose edges are colored from a set of k colors such that any two edges with a common vertex have different colors

It is shown that if a d-regular graph contains s vertices so that the distance between any pair is at least 4k, then its adjacency matrix has at least s eigenvalues which are at least 2pd − 1 cos(  2k ). A similar result has been proved by Friedman using more sophisticated tools.More generally, Serre has shown (see [3], [4] ) that for any fixed r and for any infinite family of d-regular graphs Gi, lim inf r(Gi) 2pd − 1. The same result has been proved by Friedman already in [5].

Rhinitis Medicamentosa Rhinitis medicamentosa (RM) is a condition that caused by overuse of topical nasal steroids. Also known as rebound or chemical rhinitis, the incidence is somewhere between 1-9% of non-allergic rhinitis and it is more common in younger adults and pregnant women. To understand the cause of RM, we must first look at some of the basic science behind the nasal mucosa. The mucosa is innervated by sympathetic fiber that release norepinephrine, which stimulate alpha 1 and alpha 2 receptors. This in turns causes vasoconstriction.
