OBJECTIVES This study examines the association between cultural orientation and drinking behaviors among university students. Cultural orientation is the measure of how the cultural values of individuals living in their own society are influenced by cultural values introduced from the outside. METHODS In 2011, a cross-sectional survey collected data from 1279 university students from six univ...

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.

We present a topological characterization for fuzzy regular languages: we show that there is a bijective correspondence between fuzzy regular languages and the set of all clopen fuzzy subsets with finite image in the induced fuzzy topological space of Stone space (Profinite space), and then we give a representation of closed fuzzy subsets in the induced fuzzy topological space via fuzzy regular...

Background Infertility has long been a common problem in our human history and still continues to be a problem in the modern era. Fortunately Western Medicine has developed various treatment methodologies ,especially the new assisted reproductive technology, which does increase the success rate . Despite this, nearly half of the couples among these who get treated by WM still fail conceive. The...

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...

‎let $v$ be a vector space over a field $f$ of characteristic $pgeq 0$ and let‎ ‎$t$ be a regular subgroup of the affine group $agl(v)$‎. ‎in the finite dimensional case we show that‎, ‎if $t$ is abelian or $p>0$‎, ‎then $t$ is unipotent‎. ‎for $t$ abelian‎, ‎pushing forward some ideas used in [a‎. ‎caranti‎, ‎f‎. ‎dalla volta and m‎. ‎sala‎, ‎abelian regular subgroups of the affine group and r...

in this paper, we introduce and study the concept of $r$-fuzzy regular semi open (closed) sets in smooth topological spaces. by using $r$-fuzzy regular semi open (closed) sets, we define a new fuzzy closure operator namely $r$-fuzzy regular semi interior (closure) operator. also, we introduce fuzzy regular semi continuous and fuzzy regular semi irresolute mappings. moreover, we investigate the ...

the rise of political islam and islamism in muslim countries cause a pervasive & contestable controversy among western scholars. today islam has been identified with activism, radicalism, fundamentalism, and etc. yet, there are many questions being propounded; such as, what is political islam? why islamic movements acted against interest of the west? why islamism constructed against the west? t...

OBJECTIVES To evaluate the effect of regular physical activity on metabolic risk factors and blood pressure in Inuit with high BMI consuming a western diet (high amount of saturated fatty acids and carbohydrates with a high glycemic index). STUDY DESIGN Cross sectional study, comparing Inuit eating a western diet with Inuit eating a traditional diet. METHODS Two physically active Greenland ...
