the olefins polymerization process in a slurry reactor is discussed. the reaction rate dynamics was analyzed and the contributions of feed flow, gas-liquid mass transfer, polymerization reaction, and catalyst deactivation were estimated. the propylene solubility in a solvent mixture “heptane” was calculated using soave-redlich-kwong equation of state. these data were then approximated by henry-...

The evaluation of caprock integrity and reservoir efficiency is critical for safe CO2 geological storage management. It therefore important to investigate geochemical reactions between CO2-rich fluids host rocks their contribution in retaining at depth. This study deals with diffusive reaction experiments on shales carbonate samples cored from an offshore structure the Malaysian basin, a potent...

background and aims: sexually transmitted infections (stis) are of major concern to clinicians and researchers in the field of reproductive medicine. many sti pathogens cause incurable and often fatal diseases, and have been transmitted through insemination procedures. the role of herpes simplex virus in male infertility has been investigated using the sensitive methods. the aim of this study w...

In the time-slice method, an atmosphere model is forced by the greenhouse gas concentration corresponding to a certain time in the future, e. g. normally at the time of CO2-doubling, while the sea-surface temperature (SST) and sea-ice distribution are taken from a coarse grid transient simulation. This method has the advantage that the model can be integrated with high resolution over several d...

car-following models, as the most popular microscopic traffic flow modeling, is increasingly being used by transportation experts to evaluate new intelligent transportation system (its) applications. a number of factors including individual differences of age, gender, and risk-taking behavior, have been found to influence car-following behavior. this paper presents a novel idea to calculate the...

purpose the purpose of the present study was to evaluate the ergogenic effect of caffeine ingestion on mood state, simple reaction time, and muscle power during the wingate test recorded in the morning on elite judoists. methods twelve elite judoists (age: 21.08 ± 1.16 years, body mass: 83.75 ± 20.2 kg, height: 1.76 ±6.57 m) participated in this study. mood states, simple reaction time, and mus...
