A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electromagnetic force attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds" such as dipole-dipole interactions‚ the London dispersion force and hydrogen bonding

Mechanical Engineering History of Mechanical Engineering Engineering in one form or another is among the oldest of professions. The Egyptian pyramids are examples of ancient engineering feats and many of the bridges‚ roads and aqueducts constructed by the ancient Romans are still use today. Engineers were originally simply builders who worked with stone and other basic materials. They were either self-taught or learned their craft from more experienced workers. The military operations

ESE 215 Introduction to Circuits and Systems Prepared by: The Task Group on ESE 215-205 N. Farhat‚ N. Engheta‚ J. Keenan‚ and V. Vuchic Background‚ Philosophy‚ and Motivation: Over the past few decades‚ the scope of electrical engineering (ESE in the context of our department) has expanded to a degree where the discipline risks effacement by diffusion [1]. This calls for hard thinking on how to reform traditional course offerings in our discipline in order to avoid incoherent bifurcations

balper@fh-aalen.de http://www.fbm.fh-aalen.de/ Abstract: In this article‚ we present the concept of mathematical application projects as a means to enhance the capabilities of engineering students to use mathematics for solving problems in larger projects as well as to communicate and present mathematical content. As opposed to many case studies‚ we concentrate on stating criteria and project classes from which instructors can build instances (i.e. specific projects). The main goal of this paper is to facilitate

A Critical Analysis of the Effects of Chemical Castration and Physical Castration on the Recidivism Rates of Sex Offenders Introduction This paper examines the effects of chemical castration and physical castration on the recidivism rates of sex offenders. Using theory integration or the multifactor approach‚ the findings reveal there are several factors influencing sex offender recidivism. Both chemical castration and physical castration have the potential to reduce the recidivism
