most residences of the northern parts of golestan province, have historically used rooftop rainwater for drinking. its adoption rate and continued use have declined in recent years for various reasons. based on a survey of 380 cases, this research attempted to identify what factors are contributing to the adoption of these systems. the results demonstrated that the adoption changes in response ...

We present a rapid method for apportioning the sources of atmospheric organic aerosol composition measured by gas chromatography–mass spectrometry methods. Here, we specifically apply this new analysis method to data acquired on a thermal desorption aerosol gas chromatograph (TAG) system. Gas chromatograms are divided by retention time into evenly spaced bins, within which the mass spectra are ...

introduction: general medical education starts with basic sciences which usually continue about 2.5 to 3 years. in this period, the students study basic medical sciences and then start the clinical stage in which they deal with diagnoses, care, and cure of disease. the purpose of this study was to assess the integration of basic sciences period with the clinical period at shiraz university of m...

introduction: direct and rapid access to information is one of the main necessities of the users in new technological world. nowadays, information users, particularly medical information in which rapid access is of necessity, do not have enough time to search and access to information. therefore, the present study aimed to determine strategies to access required information as soon as possible....

Squeeze film dampers (SFDs) are often used in machines with high rotational speed to reduce non-periodic behavior by creating external damping. There are some structural parameters which are of great importance in designing these systems, such as oil film thickness and inner race mass of SFD. Moreover, there is a crucial parameter associated with manufacturing process, under the title of wavine...

We show that three well-known \variational crimes" in nite elements { upwinding, mass lumping and selective reduced integration { may be derived from the Galerkin method employing the standard polynomial-based nite element spaces enriched with residual-free bubbles.

Process integration is a holistic approach to process design and operation which emphasizes the unity of the process. Process integration design tools have been developed over the past two decades to achieve process improvement, productivity enhancement, conservation in mass and energy resources, and reductions in the operating and capital costs of chemical processes. The primary applications o...
