In rat ventricle, two Ca2+-insensitive components of K+ current have been distinguished kinetically and pharmacologically, the transient, 4-aminopyridine (4-AP)-sensitive I to and the sustained, tetraethylammonium (TEA)-sensitive I K. However, a much greater diversity of depolarization-activated K+ channels has been reported on the level of mRNA and protein. In the search for electrophysiologic...

aims: chromium is one of the most important metallic pollutants in plating industry wastewater. this toxic metal is a serious threat to human health and to the environment due to its cumulative effects and non-degradability. this research intended to study the effects of ph, contact time, and voltage on the degree of chromium removal from wastewater of plating industry by using the electrocoagu...

As we move to developing object-oriented programs, the complexity traditionally found in functions and procedures is moving to the connections among components. Different faults occur when components are integrated to form higher level structures that aggregate behavior and state. Consequently, we need to place more effort on testing the connections among components. Although object-oriented te...
