today, survival and value creation in organizations depend on creative and innovative thinking as well as understanding and utilization of environmental opportunities. this research attempts to introduce the organization behavioral barriers which affect the development of corporate entrepreneurship. first, with the views of different experts, various behavioral barriers of corporate entrepreneu...

background and objectives: high performance research activity in the health domain is crucial to overcoming ever-growing health-related problems. despite availability of data sources, only a limited number of researchers use these data to derive health-related information. thus, the present study aimed at exploring the barriers to research promotion as perceived by the university health researc...

conclusions intelligence care is a comprehensive strategy that in addition to recognizing barriers and bridges of nursing care, with predisposing and precipitating forces it can convert barriers to bridges. results intelligence care emerged as a main theme, has a broad spectrum of categories and subcategories with bridges and barriers, including equality of bridges and barriers (contingency car...

diastolic phase of cardiac function is associated with lower arterial flow and hence higher concentration of intra arterially injected drug is achieved at the site of injection. it is herein postulated that drugs show higher efficacy when injected during the diastolic phase of cardiac function. it is also postulated that this benefit cannot be achieved when the drug is injected with higher rate...

increase of environmental pollution and restricted emission legislations have forced companies to produce automobiles with lower air pollutants. in this respect, discharge of blowby gases into the environment has been prohibited and their recirculation into the combustion chamber is proposed as an alternative solution. in addition, using egr technique to control and reduce nitrogen oxides in in...

a typical iranian carbonate matrix block surrounded by an open fracture was modeled in order to understand the fracture-matrix interaction and realize how to model the interaction best. the modeling was carried out by using a fine-scaled eclipse model in the single porosity mode (the fractures were explicitly modeled). the model was extended to a stack of 6 matrix blocks to understand block-to-...

co2 injection is an effective technique for improved oil recovery in light oil reservoirs, especially for water flooding abandoned reservoirs. in this study, the lower part of es1 reservoirs in pucheng oilfield was introduced as the target reservoir. by studying the minimum miscible pressure in co2 flooding, the reservoir could achieve miscible flooding. long core displacement experiments prove...

The contact resistance is known to severely hamper the performance of organic thin-film transistors. This is particular true when dealing with large injection barriers, high mobility organic semiconductors, or short channel lengths. A common assumption is that the primary quantity determining the value of the contact resistance is the injection barrier at the source electrode. Using drift-diffu...
