ECONOMIC VIEWPOINT: DOES ABORTION LOWER CRIME RATE? By: Robert J. Barro This article reviews various reasons for lower crime rates in the United States since 1991. There were many explanations offered such as better cops‚ strong economy‚ restrictions on crack cocaine.

Compare and contrast cardiac and smooth muscle. In cardiac muscle‚ each heartbeat is triggered by the hearts own pacemaker cells‚ which initiate electrical discharge and when this reaches the contractile muscle cells (the cardiomyocytes)‚ they create an action potential which increases the concentration of calcium ions into the cell. Calcium ions play a key role in activating what is known as the contractile machinery – the actin and myosin filaments. The cardiac action potential‚ unlike other forms

Designing the Instruction of the NIOSH Lower Back Model Alaina Ostroff Hofstra University Introduction This project was designed as an instruction teaching capsule for the NIOSH Lifting Equation which models forces in the lower back. This is a technical topic and was designed to teach a broad group of people‚ such as engineering students‚ as a tool to instruct the NIOSH back model. There are five elements that make up the “NIOSH Lower Back Model” which include: a narrated
