Two forms of Ca2+-dependent cysteine proteinase (calpain, EC 3.4.22.17) and their specific endogenous inhibitor (calpastatin) were partially purified from porcine retina: calpain I (low-Ca2+-requiring form) was half-maximally activated at 8 microM-Ca2+, and calpain II (high-Ca2+-requiring form) at 250 microM-Ca2+. Both calpain I and calpain II were inhibited by calpastatin. Calpain I from porci...

This survey study investigated whether viewer perceptions of reality programs’ authenticity were associated with involvement, enjoyment, and perceived learning. Four dimensions of perceived authenticity were identified: cast eccentricity, representativeness, candidness, and producer manipulation. Perceptions that the cast was not eccentric, that they were representative of people the respondent...

Guy Desaulniers and Daniel Villenueve The problem considered involves finding the minimum cost path, with cost and time being two independent quantities that govern the shortest path. In this problem, each arc is associated with a cost of traversing the arc as well as the time required to traverse it and each node is associated with a lower bound and an upper bound on the time of departure from...

The reason of this study is low cycle failure of cast iron cylinder head during the E5 standard durability test. The goal of the present investigation is durability test simulation and low cycle fatigue life evaluation of cast iron cylinder head. With uncouple structural analysis, preloads, thermal and mechanical load and boundary conditions are prescribed to finite element model of the cylinde...

In this study, the effect of slip casting parameters on the ultrafine microstructure and the density of pore-free YAG ceramic was evaluated. A stable, high concentrated aqueous YAG slurry using Dolapix-CE64 as a dispersant was prepared. The effect of dispersant concentration as well as the solid load on the stability and rheological behavior of the slurry was also studied. The optimal dispersan...

The manufacturing industry has at its disposal a number of processes for constructing objects, including gravity casting, injection molding, stereolithography, NC-machining, deformation, composition, and spray deposition. The survey by Bose and Toussaint [3, 5] gives an overview of geometric problems and algorithms arising in manufacturing processes. Castingis one of the manufacuring processes ...

We have previously shown (Sunkara et al., 1989; Taylor et al., 1991) that 6-o-butanoyl castanospermine (BuCast) was a 30-50-fold better inhibitor of HIV syncytia formation than castanospermine (Cast). Radiolabeled Cast and BuCast were used to study the uptake and metabolism of these compounds in cultured cells and in mice. BuCast was preferentially taken up by cells compared to Cast. Approximat...

CAST-128 and CAST-256 are two symmetric algorithms designed by Adams in 1990s. Both of them adopt the CAST design procedure which makes them process a number of desirable cryptographic. CAST-128 is notably used as the default cipher in some versions of GNU Privacy Guard (GPG) and Pretty Good Privacy (PGP) systems. As an extension of CAST-128, CAST-256 was submitted as a candidate for the Advanc...

The inhibitory domains of calpastatin contain three highly conserved regions, A, B, and C, of which A and C bind calpain in a strictly Ca(2+)-dependent manner but have no inhibitory activity whereas region B inhibits calpain on its own. We synthesized the 19-mer oligopeptides corresponding to regions A and C of human calpastatin domain I and tested their effect on human erythrocyte mu-calpain a...

This paper describes a new diierential-style attack, which we call the boomerang attack. This attack has several interesting applications. First, we disprove the oft-repeated claim that eliminating all high-probability diierentials for the whole cipher is suucient to guarantee security against diierential attacks. Second, we show how to break COCONUT98, a cipher designed using decorrelation tec...
