Abstract Investigation and uptake of filtered tailings continues to grow throughout the globe. This is driven by a wide range site-specific considerations, which include such factors as characteristics (e.g., amenability filtration), production rates, climate, water availability, cost drivers, environmental requirements, social factors. Despite aforementioned technological growth, currently ava...

conclusions: in this study, kidney transplant recipients with a lower ri and pi and a higher edv at 1week showed better graft function at 6 months after transplantation. results: fourteen patients (15.4%) had impaired graft function after 6 months (gfr less than 60 ml/min/1.73m2). multivariate linear regression analysis showed significant correlation between gfr at 6 months and ri, pi and edv w...

introduction : the aim of this study was to examine and compare the apical sealing ability of ah26, ah plus and ah plus jet using a fluid filtration model. materials and methods : 70 single-rooted teeth were dissected from the cement-enamel junction. canals were prepared with protaper rotary system and manual k files and irrigated with 5.25% naocl and 17% edta. ten teeth were assigned as contro...

introduction: adequate root canal seal following retreatment is essential for a successful outcome. resilon/epiphany (r/e) obturation system has been introduced as a substitute for conventional gutta-percha/sealer method. this in vitro study compared the amount of apical microleakage of r/e with gutta-percha/ah26 (gp/ah26) sealer as secondary root canal filling following retreatment in human te...

objective: the aim of this study is to measure the effect of different condensation pressure on the microleakage of mineral trioxide aggregate (mta).  methods: this study was an invitro study. a total of 55 single rooted straight-canal human extracted sound teeth free of cracks or calcification were selected. teeth were sectioned from cej region at 3 mm above the root apex. remaining specimens ...

introduction: one of the major problems in the development of nuclear medicine images is the presence of noise. the noise level in nuclear medicine images is usually reduced by the analysis of imaging data in a fourier transform environment. the main drawback of this environment belongs to low signal to noise ratio in high frequencies because removing noise frequencies may remove data and times...

stormwater represents one of the least researched forms of wastewater in environmental science. contaminated industrial stormwater, that is stormwater generated by runoff from industrial sites such as refineries, smelters and mine sites, is even less well understood. however, contaminated industrial stormwater can have damaging environmental impacts because it generally occurs in sudden bursts ...

in petroleum production, produced water re-injection (pwri) has earned much interest among disposal methods of the produced water. however, presence of the contaminants in the produced waters usually results in formation damage in well bores and their surrounding fracture systems. in the present study, modeling of external cake formation on a fracture in unsteady-state conditions is discussed. ...

However, a good reference text if you would like to buy one is Koeppen and Stanton’s Renal Physiology, 4 edition, Mosby Elsevier, 2007, For this particular lecture (glomerular filtration), Chapter 3 is the reference chapter to read in this...

May 22, 2006 issue Imagine tears, lots of tears. Imagine a trail of tears trickling across upstate New York. Judie Comerford and her husband, Michael, are in their minivan on a highway somewhere between Potsdam and their home in Buffalo. They've just bid farewell to their oldest child, Meghan, who's starting college. "I cried, and then I cried some more, and then I cried again," Judie recalls. ...
