safety distance has already been a main measurement for the hazard control of chemical installations interpreted to mean providing space between the hazardous installation and different types of targets. but, the problem is how to determine the enough space. this study considers the application of quantitative risk assessment to evaluating a compressed natural gas station site and to identify n...

ticl4, ammonia, inorganic salts as raw material, nanometer composite-crystal tio2 powders were synthesized by two-step chemical method. precursors were crystallized with different phase and stable composite-crystal tio2 with anatase and rutile phase was prepared at low temperature. quantitative control of crystal phase was realized. remarkable factors including reaction ph value, reaction time,...

background imaging plays a critical role not only in the detection, but also in the characterization of lung masses as benign or malignant. objectives to determine the diagnostic accuracy of dynamic magnetic resonance imaging (mri) in the differential diagnosis of benign and malignant lung masses. patients and methods ninety-four masses were included in this prospective study. five dynamic seri...

Background Change theories provide an opportunity for organizational managers to plan, monitor and evaluate changes using a framework which enable them, among others, to show a fast response to environmental fluctuations and to predict the changing patterns of individuals and technology. The current study aimed to explore whether the change in the public accounting system of the Iranian health ...

The paper presents a system LABAQM for the analysis of laboratory animal behaviour based on qualitative modelling. We are dealing with the cognitive phase of the laboratory animal behaviour analysis as a part of the pharmacological experiments. The system is based on the quantitative data from the tracking application and incomplete domain background knowledge. The LABAQM system operates in two...

Despite the progress that has been made in other forms of cancer therapy, Provenge® (Sipuleucel-T) is the only FDA-approved vaccine for the treatment of cancer. To understand the current landscape of therapeutic oncology vaccines we performed a quantitative analysis of phase 2 and phase 3 therapeutic cancer vaccine trials. We highlight shifts in trends for the vaccine platforms examined, common...
