Engineering Materials Msc. Shaymaa Mahmood Introduction to Eng. Materials : Since the earliest days of the evolution of mankind ‚ the main distinguishing features between human begins and other mammals has been the ability to use and develop materials to satisfy our human requirements. Nowadays we use many types of materials‚ fashioned in many different ways‚ to satisfy our requirements for housing‚ heating‚ furniture‚ clothes‚ transportation‚ entertainment‚ medical care‚ defense and all the

Introduction Molecular materials with quadratic nonlinear optical (NLO) properties are currently attracting considerable interest [1–8]. The quadratic hyperpolarizability (b) of a chromophore is associated with charge transfers between donor and acceptor substituents linked through p-conjugated pathways. Most NLO

TYPES OF MAGNETIC MATERIALS Paramagnetic materials have a small‚ positive susceptibility to magnetic fields. These materials are slightly attracted by a magnetic field and the material does not retain the magnetic properties when the external field is removed. Paramagnetic properties are due to the presence of some unpaired electrons‚ and from the realignment of the electron paths caused by the external magnetic field. Paramagnetic materials include magnesium‚ molybdenum‚ lithium‚ and tantalum

Stereotypical views in advertising have always been an issue‚ women are confined to certain gender roles‚ ways in which they can act‚ look‚ and be perceived. But these same stereotypes are doing some serious damage to society. Ads depict women with perfect figures and youthful features while the reality is the majority of women don’t look that way‚ and so this creates a sort of ideal body image. This ad is for the Beckham’s fragrance intimately BECKHAM NIGHT. David Beckham known around the world

Exposure to Stereotypes “Stereotypes are stubborn beliefs‚ overgeneralizations‚ myths‚ and distorted information about groups of people that shape people thinking and form the basis of prejudice. Stereotypes are projected through the media‚ become part of the collective consciousness‚ and are used to justify discrimination (York‚ 2006).” The media plays a huge influence on stereotypes‚ whether it is pertaining to race‚ gender‚ culture‚ or even socioeconomic status it is still influencing the views

SMART MATERIALS 1. Introduction The primary characteristic of a ‘‘smart material’’ is that it has the ability to respond to external stimuli in a technically useful and technically controlled way. The words ‘‘technically useful’’ and ‘‘technically controlled’’ are emphasized since all materials respond to external stimuli of some sort or other (as a simple example‚ all materials respond to temperature by changing their volume)‚ however‚ to be considered a ‘‘smart material’’ the response must
