In order to evaluate the informal wheat seed contamination with seed-bornediseases, two most important provinces (East Azarbaijan and Khorasan Razavi) forwheat production were selected in cold region of Iran in 2008-2009 crop seasonsand ten different locations (city or village) were considered in each province andten informal seed farmers were selected randomly. A seed sample (1 kg) was takenfr...

C.P. Snow's articulation of a two-culture divide rested on a particular view of science that has been elaborated and superseded by interdisciplinary science studies. Thus, comparisons of the 'science wars' of recent years to the Snow-Leavis controversy fail to recognize basic structural differences between the two sets of debates. In this article, I present these differences and offer some view...

We present the development of a cell clinic. This is a micromachined cavity, or microvial, that can be closed with a lid. The lid is activated by two polypyrrole/Au microactuators. Inside the microvials two Au electrodes have been placed in order to perform impedance studies on single or a small number of cells. We report on impedance measurements on Xenopus leavis melanophores. We could measur...
