In recent years the demand for small cellular handsets has grown substantially and the need for still smaller handsets continues to increase. Planer inverted-F antenna (PIFA) designs have received attention since they are compact. Although smaller sizes PIFA are needed, the design of compact antenna.....

Retinoic acid (RA) induces the differentiation of many cell types such as epithelial cells and cancer cells. Clinically, RA has been demonstrated to be efficacious in the treatment of promyelocytic leukemia, a type of blood disease. RA has also been shown to affect patterning and neurogenesis in viv.....

Cyclin-dependent kinases (Cdks) are key regulatory enzymes in the eukaryotic cell cycle. The activation of a Cdk depends on its association with its specific cyclin partner. The activity of these enzymes is further regulated by an intricate system of protein-protein interactions and phosphorylation......

Traditional methods for resistivity measurements of concrete have to use two plate electrodes at opposite sides of a prism specimen. The major drawback of such a method is that the electrodes can be easily detached from the specimen due to shrinkage of concrete. Thus the measurement of resistivity.....
