Single input current-sensing differential logic (SCSDL)

A new novel single input current-sensing differential logic (SCSDL) is proposed. The SCSDL is flexible-in particular high input Boolean logic functions can be implemented with low complexity, area consumption, time delay, and power consumption. The first part of the area saving comes from the remarkable reduction of wiring; the other part comes from the very low number of transistors needed to imp

Den administrativa hållningen - En tidstypisk orientering bland samordnare i ungdomsvårdens projektvärld?

Organisatoriska former av en formaliserad, administrativ karaktär ter sig nästan ofrånkomliga i dagens ”projektvärld” (Sahlin, 1996, Sulkunen, 2007). Referensgrupper och arbetsgrupper utgör i allmänhet, en överbyggnad. Till denna hör också krav på dokumentation och planer: en vid variation av byråkratiska formulär. I det här utvärderade projektet, en vårdkedja inom ungdomsvården, karakteriserades

Human vascular alpha-adrenoceptors. A study of peripheral arteries and veins in vitro and in vivo.

By means of a sensitive myograph and alpha-receptor subtype selective agonists and antagonists the postjunctional alpha-adrenoceptors were characterized in small omental and groin arteries and veins and in long saphenous veins obtained from 52 "healthy" adults during surgery. These vessels were found to have a mixed population of contraction mediating postjunctional alpha-receptors with a predomin

Downgrading Iranian-British Relations: The Anatomy of a Folly

Yet, as indicated, the most significant corollary of the diplomatic crisis in Iranian-British ties concerns the cataclysmic impact it can exert upon the likelihood of military confrontation with Iran. It is a gross miscalculation on the part of Iranian politicians and policy-makers to suppose that occupation of the UK embassy or reduction of relations with the country will “teach it a good lesson,

Importance of vertex corrections for obtaining correct selection rules in the theory of photoemission

It is shown that the commonly used approximation for the no-loss angle-resolved photocurrent from solids in general violates the optical selection rules if the final-state inverse low-energy electron diffraction orbital is taken to be damped. The violations occur in the velocity formula, which is inconsistent with the corresponding and commonly used acceleration formula in which the matrix element

Coupled simulation approaches for PEM fuel cells by OpenFOAM

Proton exchange membrane (PEM) fuel cells are known as environmental friendly energy conservation devices, and have the potential to be suitable alternative power sources. The cost and durability of a PEM fuel cell are strongly affected by the involved transport phenomena and reactions, which are two major challenges to be overcome before commercialization. Modeling and simulation are crucial for
