legal questions. The criminal case has, from its peculiar associations, which it is unnecessary for us further to allude to, excited an unusual degree of professional and public interest, and has given rise to much animadversion and discussion in the public and medical journals of the day. This case will, from its peculiar features, take a prominent position among the Causes Celebres of British...
this thesis basically deals with the well-known notion of the bear-invariant of groups, which is the generalization of the schur multiplier of groups. in chapter two, section 2.1, we present an explicit formula for the bear-invariant of a direct product of cyclic groups with respect to nc, c>1. also in section 2.2, we caculate the baer-invatiant of a nilpotent product of cyclic groups wuth resp...
in the first part of this thesis we explored wetting and its dynamics for small droplets. first, we showed how a simple feature of water droplets on a surface, i.e. laplace pressure, can be exploited to build a micropump. we investigated capillary pumping in microchannels both experimentally and numerically. putting two droplets of different sizes at the in/outlet of a microchannel, will ge...
large-scale allocation problem (lsap) is considered to be an important problem in operations research. in this paper, we have tried to model a sample lsap and show that famous linear or approaches in use cannot efficiently help us challenge, develop and handle such cases. we begin with efforts in this area to conclude that timely, efficient and less costly solutions could be only developed unde...
the concepts of similarity and dissimilarity have been the interest of many researchers. basically, in the studies the similarity between two objects or phenomena, has been discussed. in this thesis, we consider the case when the resemblance or similarity among three objects or phenomena of a set, 3-similarity in our terminology, is desired. later we will extend our definitions and propos...
NITROUS oxide is a funny gas. It got off to a less than auspicious start when Horace Wells was humiliated by boos and jeers when he administered it for surgery the first time at Massachusetts General Hospital (Boston, Massachusetts) on January 18, 1845, and his patient, having the mask removed too soon, cried out with pain. It is implicated in a litany of well-known problems even today: nausea ...
Metabolic studies of lipoproteins have yielded important insights into regulation of energy distribution as well as providing fundamental understanding of cardiovascular risk properties of different lipoproteins. Although many factors on the molecular level have the potential to impact metabolic regulation of lipids, metabolic studies provide valuable information from a comprehensive regulatory...
We present a method to gauge second class systems consisted of two constraints in the chain structure. In this method we added a momentum counterpart of Wess Zumino coordinate to primary constraint and used the first class condition to find a new and gauged Hamiltonian. Primary constraints were assumed as identities in configuration and phase space and we tried to find general Hamiltonians
