In this paper, loss probabilities and steady state probabilities of data packets for an asynchronous transfer mode (ATM) network are investigated under the buffer division and push-out schemes. Data packets are classified in classes k which arrive in Poisson fashion to the service facility and are served with general service rate under buffer division scheme, finite buffer space N is divided in...

Contractions in whole skeletal muscle during hypoxia are known to generate reactive oxygen species (ROS); however, identification of real-time ROS formation within isolated single skeletal muscle fibers has been challenging. Consequently, there is no convincing evidence showing increased ROS production in intact contracting fibers under low Po₂ conditions. Therefore, we hypothesized that intrac...

Organizational commitment has been one of the most popular work attitudes studied by practitioners and researchers. This article seeks to investigate the mediating role of psychological contract (PC) in the relationship between person-job (PJ) fit, person-organization (PO) fit and organizational commitment (OC). The target population for this study consists of support staff of Iran’s national g...

The increase in cardiac output during' isoproterenol administration has been attributed to a direct action on the heart causing it to extract blood more effectively from the central venous reservoir (1). Another suggestion is that isoproterenol constricts peripheral veins and causes blood to be pushed into the heart (2). The observation that right atrial pressure falls during infusion of the dr...

BACKGROUND Canada has featured the second-highest levels of prescription opioid (PO) use globally behind the United States, and reported extensive PO-related harms (e.g., non-medical PO use [NMPOU], PO-related morbidity and mortality). A recent comprehensive review synthesized key data on PO use, PO-related harms, and interventions in Canada, yet a substantive extent of new studies and data hav...

Catalases are ubiquitous hydrogen peroxide-detoxifying enzymes. They participate in fungal growth and development, such as mycelial growth and cellular differentiation, and in protecting fungi from oxidative damage under stressful conditions. To investigate the potential functions of catalases in Pleurotus ostreatus, we obtained two catalase genes from a draft genome sequence of P. ostreatus, a...

In 2001, S. Bulman-Fleming et al. initiated the study of three flatness properties (weakly kernel flat, principally weakly kernel flat, translation kernel flat) of right acts $A_{S}$ over a monoid $S$ that can be described by means of when the functor $A_{S} otimes -$ preserves pullbacks. In this paper, we extend these results to $S$-posets and present equivalent descriptions of weakly kernel p...
