An Investigation Into Residual Stresses Formed by Bending and Quenching Processes
, M.Sc. Thesis Sharif University of Technology ; Karimi Taheri, Ali (Supervisor)
Abstract
Various forms of springs are applicable, among which spiral and leaf springs can be named. Definition of leaf springs is conventionally applied to constant-width springs and is consisted of step-like leaves, each leaf having constant width. Leaf springs are largely used in vehicles, where they act as a part of suspension system supporting the weight of the vehicle along with connecting spots axles to the chassis. Springs so installed are capable of handling starting and stopping torques as well as sudden vibrations due to load carrying. Most Conventional method of manufacturing leaf springs is to bend strips of appropriate steel between curved dies, quench the strip while held between the...
Spectroscopic Study and Characterizing of Selenium Dioxide Complex with Pyridoxine(PN-Se):Interaction Between (PN-Se)and Bovine Serum Albumin
, M.Sc. Thesis Sharif University of Technology ; Mohamadi Boghaei, Davar (Supervisor)
Abstract
Temporary existence of some molecules like medicines in body and also existence of diagnostic agents in biological systems and study of the interactions of biomolecules with these agents is a matter of interest. It also may have an important role in design and synthesis of new drugs. Serum Albumin is the most abundant protein in circulation system in the body. So far, many studies about the interaction of this protein with different compounds have been undertaken. The aim of this paper was to synthesize selenium complex and analyze its potential biochemical activity in vitro. The concrete work falls into two parts:(1) to synthesize the selenium-pyridoxine compound (PNSe) (2) to probe into...
