The FEMLAB code based on weak formulation of PDE’s problem was used at a solution of feedback thermo-mechanical interaction in pre-pressed rubber block used for resilient elements of the composed tram wheels. The structural motion and heat conduction equations are solved interactively as time dependent problems. The equality of heat energy density and dissipation energy density realizes the cou...

Sensors are becoming ubiquitous and can be combined in arrays for source localization purposes. If classical conventional beamforming is used, then random arrays have poor beampatterns. By pre-computing sensor weights, these beampatterns can be improved significantly. The problem is formulated in the frequency domain as a desired look direction, a frequency-independent transition region, and th...

mucoadhesive polymers that bind to the gastric mucin or epithelial cell surface are useful in drug delivery for the purpose of increasing the intimacy and duration of contact of drug with the absorbing membrane. several synthetic polymers are in use for this purpose. since the biodegradability of the synthetic polymers are questionable, in this investigation, an oral mucoadhesive controlled del...

organophosphorus compounds are highly toxic chemicals that have application in production of warfare agents and agricultural pesticides. detoxification of areas that have been exposed to these types of materials is of vital importance and several approaches have been used for this purpose. biodegradation of organophosphates is one of these approaches that is in the center of attention due to it...

long protocol of gonadotropin-releasing hormone-analougue (gnrh-a) can result in the formation of ovarian cyst by the transient initial stimulatory effect which increases the levels of both follicle-stimulating hormone (fsh) and luteinizing hormone (lh). these cysts require surgical drainage or result in poor ovarian response. ovarian cyst formation can be prevented by taking oral contraceptive...

chemotherapy research highly prioritizes overcoming the multidrug resistance (mdr) in human tumors. liposomal formulation of fluoxetine, as a fourth generation chemosensitizer, was constructed and characterized for percent entrapment, release profile, morphology, particle size, zeta potential and stability. liposomes were prepared using different active loading techniques. the influence of diff...

the ever severe dynamic competitive environment has led to increasing complexity of strategic decision making in giant organizations. strategy formulation is one of basic processes in achieving long range goals. since, in ordinary methods considering all factors and their significance in accomplishing individual goals are almost impossible. here, a new approach based on clustering method is pro...

in this study, the optimum combination of major factors affecting the acceptability of whey-based ricotta cheese i.e. fat at three levels (0, 5, 10%), salt at three levels (0, 1, 2%), and starter culture at two levels (0, 3%) was determined in a complete randomized design method with a factorial experiment. ricotta cheese trials made by mixing whey and milk in a ratio of 5:1 were then organ...

Research about Group Support Systems and the design of these technologies uses western culture as a point of reference. While the research reveals promising results on the effectiveness of these technologies, the technologies may be less effective when applied directly to different cultures or cross-cultural situations where there may be different support requirements. This paper presents the c...
