background: apical leakage assessment is a way to compare the effi ciency of a fi lling material to seal the apical region of the tooth. many microleakage testing techniques have been introduced through the years, but there has been no agreement as to which technique gives the most accurate results. the aim of this study was to compare the accuracy of fl uid fi ltration and bacterial leakage te...

objective(s): one applications of nanotechnology is in the area of medicine which is called nanomedicine. primary instruments in nanomedicine can help us to detect diseases and used for drug delivery to inaccessible areas of human tissues. an important issue in simulating the motion of nanoparticles is modeling blood flow as a newtonian or non-newtonian fluid. sometimes blood flow is simulated ...

This paper studies the uid approximation (also known as the functional strong law-of-large-numbers) and the stability (positive Harris recurrent) for a multiclass queueing network. Both of these are related to the stabilities of a linear uid model, constructed from the rst-order parameters (i.e., long-run average arrivals, services and routings) of the queueing network. It is proved that the ui...

flow field and heat transfer of a nanofluid, whose non-newtonian behavior has been demonstrated in the laboratory, in a square enclosure have been numerically modeled and investigated. to estimate the viscosity of nanofluid, experimental data of hong and kim, 2012 have been used, and a new model has been proposed. finally, the obtained results have been compared to those of newtonian behavior. ...

EditorÐWe read with interest the review concerning the pathophysiology and clinical implications of perioperative ̄uid excess. However, we were surprised and have to disagree with the conclusion that there is a need for randomized, prospective clinical studies to compare `high' vs `low' ̄uid regimens. We were `surprised' because the authors highlighted two excellent studies where appropriate plas...

The dynamics of the uid elds in a large class of causal dissipative uid theories is studied. It is shown that the physical uid states in these theories must relax (on a time scale that is characteristic of the microscopic particle interactions) to ones that are essentially indistinguishable from the simple relativistic Navier-Stokes descriptions of these states. Thus, for example, in the relaxe...

shock for three days or more who received higher fl uid volumes had reduced mortality. Th is is an important issue because how much fl uid is enough for critically ill patients has been controversial for a long time. Th e optimal fl uid status should be set according to the prevailing conditions. In contrast to this study, most previous studies have found that a more positive fl uid balance is ...
