Background: Northern regions of Iran have been encountered to dominate malignancies of gastrointestinal (GI) tract. We came to examine the total excess mortality due to the GI cancer in Mazandaran province. Methods: Socio-demographic and clinical data of 484 patients with GI cancer collected during the years 1990-1991were available from Babol Cancer Registry. Patients were followed up for 15 ye...

The seesaw mechanism is introduced and some of its different realizations and applications are discussed. It is pointed out how they can be used to understand the bi-large mixing patterns among neutrinos in combination with the assumptions about high scale physics such as grand unification or quasidegeneracy of neutrino masses.

We examine the structure of the quaternion group Q8 and its possible application to the physics of flavor. We find that a Q8 family symmetry is suitable to explain the difference between quark and lepton mixing patterns. Distinctive phenomenological predictions are derived for the neutrino sector and the electroweak Higgs sector. We also show how the Q8 symmetry suppresses the effective operato...

Patient treatment processes require the cooperation of different organizational units and medical disciplines. In such an environment an optimal process support becomes crucial. Though healthcare processes frequently change, and therefore the separation of the flow logic from the application code seems to be promising, workflow management technology has not yet been broadly used in healthcare e...

With the increase in multi-cultural families, Korea is seeing a rapid increase in immigrated housewives, who are closely related to food culture. However, studies for the diet of multi-cultural families, which is most closely related to our lives have not been sufficiently researched. With this background, this study conducted research for immigrated women nationwide about food cultures to prov...

Understanding the disparate mixing patterns between quarks and leptons is one of the major challenges in particle theory today. I discuss some of the ways to understand this difference within the seesaw framework using new symmetries of quarks and leptons. After a brief introduction to the various types of seesaw formulae, proposals for understanding large solar and atmospheric mixings for the ...

Paradoxically enough, the impression left on the reader by Georges Sadoul's admirable book on the origins of the cinema is of a reversal, in spite of the author's Marxist views, of the relations between an economic and technical evolution and the imagination of those carrying on the search. The way things happened seems to call for a reversal of the historical order of causality, which goes fro...

this essay considers the implications of the demographic transition for the emergence of modern democracy. although the idea of representative democracy was present in europe and north america in the late eighteenth century, here i am concerned with its realization—and this occurs much later. i argue that consideration of the demographic transition in western countries sheds light on what is so...
