glucose-6-phosphate dehydrogenase (g6pd) deficient subjects are vulnerable to oxidative stress. quercetin, a flavonoids, has been employed as a potent oxygen-free radical scavenger in order to assess the protective effects of quercetin against h2o2-induced oxidative damage in g6pd-deficient and normal human erythrocytes. erythrocytes of g6pd-deficient (n = 10) and normal (n = 10) subjects were ...

We present a collision attack on the hash function HAS-160 reduced to 53-steps. The attack has a complexity of about 2 hash computations. The attack is based on the work of Cho et al. presented at ICISC 2006. In this article, we improve their attack complexity by a factor of about 2 using a slightly different strategy for message modification in the first 20 steps of the hash function.

in the 1970 s, regulations in some counries forced usersof heavy residue to limit pollutant emissions at industrial sites, also forced producers to up grade their heavy products for export and domestic use. for this reason iran as a producer, exporter and consumer has to develop mew upgrading processes.the most common processes for upgrading heavy oil are catalytic processes, but existence of h...

Class C physiologic incident reports during undergraduate pilot training (UPT) revealed that 1.7 episodes of G-induced loss of consciousness (LOC) occurred monthly in 1980-1984. The mean +Gz for the LOC episodes was +3.8 Gz; the minimum, +2.0 Gz. The mean time of total incapacitation was 12.0 s (maximum, 180.0 s) as subjectively estimated by the aircrew. Improper performance of the anti-G strai...

Searching for educational resources on the web would be greatly facilitated by the availability of classificatory metadata, but most web educational resources put up by faculty members provide no such metadata. We explore using text classification and information extraction techniques to automatically gather such metadata. Text classifications orthogonal to topic matter appear possible with hig...
