Unimolecular rate theory for various types of reactions is implemented for any looseness of transition state. Quantum states are counted for all but the ‘‘transitional’’ modes, their phase space being counted via Monte Carlo sampling. The rate constant kEJ is then weighted with the initial E and J distributions. 2013 Elsevier B.V. All rights reserved.
To assess the importance of endothelial intercellular adhesion molecule-1 (ICAM-1) in microvascular leukocyte kinetics in diseased lungs, we investigated the transitional changes in ICAM-1 expression, vascular diameter, and leukocyte behavior in rat pulmonary microcirculation during the development of acute lung injury (ALI) and chronic fibrosis (FIB) evoked by bleomycin (BLM). Observations wer...
Sex allocation theory predicts that growth rates should influence the optimal size at sex change, with sex change occurring at larger sizes with increasing growth rates. We examined how variation in food availability affects growth rates and therefore influences size at sex change in 2 protandrous calyptraeid gastropods, Crepidula cf. marginalis and C. incurva. The lowest food concentration tes...
the major purpose of this study was to develop the translation teacher competency test (ttct) and examine its construct and predictive validity. the present study was conducted in two phases: a qualitative phase as well as a quantitative phase. in the first phase of the study, the author attempted to find out the major areas of competency required for an academic translation teacher. the second...
Simulations of complex systems models provide a numerical laboratory for studying emergent spatial phenomena. We report on simulations of the 2dimensional spatial prisoners’ dilemma with both 4and 8-neighbour playoffs. We identify non-monotonic dependence of the convergent population of defectors with the variation of defection temptation reward in the 8-neighbour system. We present somemicrosc...
background and aims: immunohistochemical tests are one of the most important tests, which are under study to determine the prognosis of the cancers such as transitional cell carcinoma. by the time, flexible cystoscopy and urine cytology are the routine tests for following up the patients with transitional cell carcinoma, which are both operator dependent. on the other hand, cystoscopy is an inv...
Some important discrepancies in weather forecast for urban area during frontal zones’ transitional periods are constantly observed, when air pollution is combined with electromagnetic smog. Often the days’ lasting phenomenon is due to an unstable phase in humidity transition, which is generated by electromagnetic smog stimulation of anthropogenic aerosol aggregation. This result is a fog-like c...
Summary In this study, the seismic performance of hexagrid structures which are composed of horizontal and vertical hexagrid by using a transitional story, has been investigated. To this end, 10 models of 50-story hexagrid structures were designed. 9 models with horizontal hexagrid cells which transited to vertical cells using a transitional story, and a model of completely horizontal hexagrid ...
