objective(s): the novel 7-hydroxycoumarinyl gallates derivatives are detected in many pharmaceutical compounds like anticancer and antimicrobial agents. whereas carbon nanotubes (cnts) have been discussed for nanomedicine applications and in particular as drug delivery systems. the capability of armchair (5, 5) swcnt -based drug delivery system in the therapy of anticancer has been investigated...

It is suggested that a unifying description of leptons and hadrons can be obtained within a nonabelian gauge theory where the gauge group is a symmetry group of a set of massless elementary fermions (leptons, quarks). We investigate the consequences of such an approach for the strong, electromagnetic, and weak interactions. We study both gauge theories with and without fermion number conservati...

In biand multilateral interactions, parties frequently make weak commitments, i.e., commitments to future actions from which they may nonetheless deviate at some cost. For example, partners in a strategic alliance usually increase their mutual commitment step by step, where intermediate stages imply only a weak commitment. This paper proposes a new mechanism by which weak commitments lead to im...

Large flux uncertainties and small cross sections have made neutrino scattering physics a challenge. However, a worthwhile challenge, as these tiny particle interactions can teach us a lot about neutrinos themselves, the weak interaction, and nucleon structure. As well, knowledge of these cross sections is crucial input to the growing field of neutrino oscillation physics. New, intense, well un...

Let me begin by thanking Bernard Frois and the Organizing Committee for making it possible for us to enjoy both the 1998 International Nuclear Physics Conference and the lovely city of Paris. My charge today is to summarize fundamental symmetries and theory, a topic with a rich history in nuclear physics. A generation ago nuclear studies of β decay helped established the V-A nature of the weak ...

The top quark, discovered at the FERMILAB TEVATRON collider in 1995, is the heaviest known elementary particle. Today, ten years later, still relatively little is known about its properties. The strong and weak interactions of the top quark are not nearly as well studied as those of the other quarks and leptons. The strong interaction is most directly measured in top quark pair production. The ...

A primary objective of particle physics since the 1964 discovery of CP non-conservation in weak decays has been the understanding of the effect as a natural feature of the structure of the weak interaction. A clue was offered in 1973 by Kobayashi and Maskawa in anticipation of the discovery of a third fermion family. With three families the unitary transformation to the weak isospin basis of th...
