Abstract Distal renal tubular acidosis (dRTA) is characterized by an impaired ability of the distal tubule to excrete acid, leading metabolic acidosis. Associated complications include bone disease, growth failure, urolithiasis and hypokalaemia. Due its rarity, there limited evidence guide diagnosis management; however, available data strongly suggest that control alkali supplementation can hal...

in this paper, using the best proximity theorems for an extensionof brosowski's theorem. we obtain other results on farthest points. finally, wedene the concept of e- farthest points. we shall prove interesting relationshipbetween the -best approximation and the e-farthest points in normed linearspaces (x; ||.||). if z in w is a e-farthest point from an x in x, then z is also a-best ...

Automatic estimation of mouth features is one of the important topics for face recognition and model–based coding of videophone sequences. In this contribution, an automatic mouth feature estimation algorithm which uses deformable templates is developed. Here, the mouth features are represented by the corner points of the mouth as well as the so called lip outline parameters. The lip outline pa...
