Objectives When a patient has cone beam computed tomography (CBCT) images based on the treatment plan, it is possible to use these images for evaluation of caries, and there is no need for new radiographs, according to the "as low as reasonably achievable" (ALARA) principle. The aim of this study was to determine the effect of filtration and thickness of CBCT cross-sections on detection of prox...

Date juice was treated by cross- flow ultra-filtration with molecular weight cut-off (MWCO) of 5 kDa. Optimized levels of feed brix, TMP and operation time were determined as 47.13, 82.11 psi and 30 min, respectively. Under such conditions, 80.94% decolourisation and 97.78 % turbidity reduction were obtained while loss of glucose and fructose were estimated to be only 3.49% and 9.62%, respectiv...

The present study shows a method to recover lead metal from wastewater of wet scrubber in secondary lead smelter. The wastewater is loaded with 42,000 ppm of insoluble lead compounds (TSP) submicron in diameter. The technical background benefits the use of cationic polyfloc solution to flocculate these colloidal solids before press filtration. The polymer solution is injected in the wastewater ...

Earlier publications questioned the reliability of measurements of renal plasma flow in young infants, since the extraction ratios for para-aminohippurate (EPAH) used were those obtained in adults (1-3). It was suggested that the use of these high values for EPAH to determine renal plasma flow and filtration fraction might not be valid and could account for the high filtration fraction reported...

The metal-organic framework (MOF) MIL-68(In)-NH2 was tested for dye removal from wastewater and carbon capture gas separation. synthesized as a neat, supported MOF thin film membrane spherical particles using pyridine modulator to shape the morphology. neat membranes were employed in cross-flow geometry, demonstrating strong molecular sieving. used electrospinning of poylethersulfone mixed-matr...

Feeding of ciliates on suspended food particles is complex and relies typically coordinated motion in bands transversal rows cilia known as membranelles. We explore model the fluid dynamics feeding flow particle retention upstream collecting that use a single membranelle band to both generate flow, retain particles, transport them cell mouth.

Interfacial polymerization of polyamide was conducted using hydrophobic and hydrophilic membrane support. The effects monomer concentration were investigated, the resulting thin-film composite membranes tested for their performance in dye removal different flow configurations. results showed that a dense layer successfully formed on support, while with very loose structure became smoother more ...

To study if the severity of hypertension could be associated with disturbances of the autoregulation of renal blood flow and glomerular filtration, we compared the renal hemodynamic and functional responses to acute blood pressure reductions of a group of patients with moderate essential hypertension (n = 10) with those of a group of patients with severe hypertension (n = 10). Blood pressure wa...

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers. L’archive ouverte pluridisciplinaire HAL, est destinée au dépôt et à la diffusion de documents scientifiques de niveau...
