Recent studies comparing terrestrial versus aquatic locomotion in animals have shown that changes in kinematics, muscular activation patterns, and performance across media are often dramatic. Surprisingly, however, despite the importance of feeding to the survival of most animals, few studies have compared differences in feeding behaviour between media. The present study compares prey-capture b...

Background:Body packers occasionally refer to the Emergency Department (ED), after leakage of package contents within intestinal lumen, resulting in life-threatening toxicities, depending upon the nature of the chemical product. Case Presentation: We present a case report of a patient presented with sudden onset of drowsiness while he was on board a flight. He was brought in by the airport secu...

b a ckground: a two year seroepidemiological study was designed to find out the seroprevalence and risk factors ofcanine visceral leishmaniasis (cvl) among stray and owned dogs in tehran and alborz provinces of iran. me t hods: blood samples of  602 dogs living in  11  counties of  tehran and  alborz  provinces were  taken by venipuncture in 2008–2010. after separation of blood sera, anti-leish...

There is an increasing need for secure and fast encryption algorithms to support applications communication protocols, business models. In this paper, we present alternative stream cipher (Strike) inspired by the stochastic behaviour of lightning strike phenomena. The novelty originality Strike stem from utilisation as a source generating random keystreams decryption. consists three main functi...

Background and Aims: Bovine viral diarrhea virus (BVDV) is considered as worldwide and economically significant infection. The aim of this study was to estimate prevalence of persistent bovine viral diarrhea infection (PI) in industrial dairies of Tehran and Alborz province, Iran. Materials and Methods: In this cross-sectional study, 102371 blood samples were collected from bovine of industria...

During running, the foot collides with the ground approximately 1000 times per mile. These collisions vary significantly by the strike pattern that the runner adopts. A rearfoot strike pattern results in a very distinct vertical impact peak that is missing in a midfoot or forefoot strike landing (Figure 1) [1]. The impact peak of a rearfoot strike is associated with higher rates of loading comp...

We studied the defensive strike of one species of each of five recognized lineages within the genus Bothrops, namely, B. alternatus, B. jararaca, B. jararacussu, B. moojeni and B. pauloensis. The defensive strike of the studied species was in general similar to that of Crotalus viridis and C. atrox, but some important differences were observed. Bothrops alternatus and B. pauloensis struck prefe...
