The phase image in radionuclide ventriculography shows the timing of ventricular contraction and is valuable in the detection of abnormalities induced by coronary artery disease. The image is usually interpreted subjectively, and in the present study a histogram of left ventricular phase values was used to make interpretation more objective. The left ventricular ejection fraction and the standa...

Phase separated borosilicate glass samples were prepared by applying various heat treatments. Using selective chemical etching we performed AFM measurement on the phase separated glass surfaces. A quantitative roughness analysis allowed us to measure precisely the dependence of the characteristic size of the phase domains on heating time and temperature. The experimental measurements are very w...

We introduce an optical microscopy technique aimed at characterizing the heat generation arising from nanostructures, in a comprehensive and quantitative manner. Namely, the technique permits (i) mapping the temperature distribution around the source of heat, (ii) mapping the heat power density delivered by the source, and (iii) retrieving the absolute absorption cross section of light-absorbin...

introduction: evaluation of nurse-patient communication skills have been strongly emphasized in order to ensure the possibility of effective communication as well as assessment of the effect of communication skills training programs. reaching this goal requires the use of standard instruments which is based on the native culture of the target group. due to the absence of native instruments in t...

the growing attention to formulaic sequences during the last decade indicates that the functional features of such sequences play a crucial role in writing. formulaic sequences are prefabricated linguistic components which are stored and retrieved as a whole. the present study aims to examine the functional features of such sequences in persian writings. to do so, 10 writing samples of persian ...

The critical success factors (CSFs) of knowledge management (KM) systems are considered as areas that must be given the required attention for the successful implementation of knowledge management. In this respect and to reduce the failure risk of knowledge management projects, the current paper aims to arrive at a conceptual model by identifying and prioritizing factors for guiding research in...
