in this study digital image correlation (dic) technique combined with a high speed video system was used to predict movement of particles in a water model. comparing with particle-image velocimetry (piv) technique, it provides a low cost alternative approach to visualize flow fields and was successfully employed to predict the movement of particles in a water model at different submergence dept...

PURPOSE The purpose of this study was to compare the sealing ability of temporary restorative materials at 24 hrs and 1 week. MATERIALS AND METHODS Endodontic access cavities were prepared in 56 extracted lower incisor-teeth and divided into 5 groups (n=10). Standard 5 mm deep access preparations were completed and root canals were prepared to size ISO #30 file. The access cavities were resto...

Fluid overload is one of the major presentations in patients with late stage chronic kidney disease (CKD). Diabetes is the leading cause of renal failure, and progression of diabetic nephropathy has been associated with changes in extracellular fluid volume. The aim of the study was to assess the association of fluid overload and diabetes in commencing dialysis and rapid renal function decline ...

We studied the pulmonary vascular response to hypoxia and associated transvascular flux of fluid into the lungs of newborn lambs. After a 2-hour baseline period, 14 unanesthetized lambs, 1-3 weeks old, breathed 10-12% oxygen in nitrogen for 3-6 hours. We measured steady state lung lymph flow, pulmonary arterial and left atrial pressures, blood flow to the lungs, and the concentration of protein...

In our previous article (Am J Physiol Adv Physiol Educ 272: S26-S30, 1997) we proposed a model that permits analysis for the change of hemodynamics in vessels with local stenosis. This problem is connected with the blood-tissue metabolism. This article continues the classroom research on concepts related to blood flow physiology. We take into consideration the problem of the blood-tissue fluid ...

Clinical diagnosis of tuberculous meningitis (TBM) is difficult due to the disease’s inconsistent clinical presentation. Furthermore, owing to the paucibacillary nature of cerebrospinal fluid (CSF), traditional techniques for detecting acid-fast bacilli have limitations. Hence, isolating mycobacteria from CSF by culture is a challenge. There is a dire need to improve, accelerate, and enhance is...

This chapter evaluates and compares the indoor performance of different concentrations non gelatinized starch in drilling fluid, modified at 80°C, then aged high temperature. Taking plastic viscosity (PV) filtration loss (FL) as main evaluation indexes, a formula with better was selected additive used follow-up study. At same time, inhibition water-based fluid investigated.

Edema formation in acute inflammation can be induced through lowering of interstitial fluid pressure (Pif) and seems to involve dynamic t3l integrin-mediated interactions between dermal cells and extracellular matrix fibers. The present experiments investigate the role of I31 integrins in the control of Pif. The anti-inflammatory drug a-trinositol (1,2,6D-myo-inositol trisphosphate) stabilizes ...

The rheological and filtration properties of drilling mud under down-hole conditions may be very different from those measured at ambient pressures and temperatures at the surface. This paper presents the results of an experimental investigation into the temperature and salinity and pH effects on drilling mud rheological and filtration properties. Results are given from tests on water base mud ...
