Starting from the random phase approximation for the weakly coupled multiband tightly-bounded electron systems, we calculate the dielectric matrix in terms of intraband and interband transitions. The advantages of this representation with respect to the usual plane-wave decomposition are pointed out. The analysis becomes particularly transparent in the long wavelength limit, after performing th...

The aim of this project is to develop an e-education system for the continuing education (CE) needs of pharmacists. The e-learning system assumptions were ease of use for end-users, easy to administer, to assist development and rebuild ability and the possibility to deliver both a wide range of helpful multimedia materials and online tests and role-play quizzes. During the trial period over 250...

Introduction Subjects ranging from chromatin remodelling to ageing, from human disease to avian song, and from metabolism and the cell cycle to structural biology and differentiation were all covered at this keystone symposium, and illustrate the diversity of forkhead transcription factors and their regulatory functions. Forkhead transcription factors, or ‘FoX’ proteins, are unified as a family...

i The thesis entitled “Uses of Pyrrole Amino Acid based Scaffolds in Peptidomimetics and Studies Directed Towards the Total Synthesis of Antascomicin A”, consists of three chapters: CHAPTER I: Deals with the synthesis and conformational studies of pyrrole amino acid based peptidomimetics. This chapter is divided into two parts: Part A: Describes the synthesis and conformational studies of linea...

Statistical power depends on the size of the effect of interest. However, effect sizes are rarely fixed in psychological research: Study design choices, such as the operationalization of the dependent variable or the treatment manipulation, the social context, the subject pool, or the time of day, typically cause systematic variation in the effect size. Ignoring this between-study variation, as...

The lines of the Mg I spectrum, lying in the visible and in the photographic infrared regions, have been examined and some of them found to show structure. It is pointed out that the structure should be attributed to isotope shift, which, in the case of the 3s3p 'P —3s3d 'D series, owes its origin to the fact-that the smd 'D terms, perturbed by the p''D term, have passed on to this term some of...

The simultaneous effects of soil and existing structures are known as the site-city interaction (structure-soil-structure). The impact of site-city interaction on structure behavior is effective. Thus, this interaction in some regions decreases the responses while increases in other areas. In addition, the site-city interaction of many parameters including the soil type, density rate, height of...

In a shell and tube heat exchanger, the failure of tube-to-tubesheet welds results in high-pressure water jet which erodes the refractory in front of the tubesheet. Finite element method was employed to simulate the welding process and post weld heat treatment (PWHT) to find the factors affecting the failure in tube-to-tubesheet weldments. Residual stresses in two different geometries of tube-t...
