iran has limited water resources that require preservation and reducing water loss from reservoirs, especially in arid and semi arid regions. there are a number of methods available for to control water loss from reservoirs and canals. concrete linings in water reservoirs and ponds are durable, but their efficiency is limited. geomembrane sheets are another method of controlling leakage from wa...
conclusions fuji plus cement exhibited better sealing ability in closed and open margins compared to g-cem and fleck cements. when using g-cem and fleck cements for full metal ceramic restorations, clinicians should try to minimize marginal gaps in order to reduce restoration failure. in situations where there are doubts about perfect marginal adaptation, the use of fuji plus cement may be help...
The goal of leakage-resilient cryptography is to construct cryptographic algorithms that are secure even if the devices on which they are implemented leak information to the adversary. One of the main parameters for designing leakage resilient constructions is the leakage rate, i.e., a proportion between the amount of leaked information and the complexity of the computation carried out by the c...
Background: Leakage is common in patients receiving home mechanical ventilation (HMV) via a face mask. Although pressure ventilators have partial compensatory capacity, excessive leakage can compromise the effectiveness of treatment. Home ventilators are equipped with built-in software which provides information on leakage. However, the values of leakage and their effects in routine clinical pr...
Due to the superlinear dependence of leakage power consumption on temperature, and spatial variations in on-chip thermal profiles, methods of leakage power estimation that are known to be accurate require detailed knowledge of thermal profiles. Leakage power depends on the integrated circuit (IC) thermal profile and circuit design style. Here, we show that piecewise linear models can be used to...
Leakage rates were determined from leaf cells loaded with rubidium and [(3)H]leucine. There was a differential response between leucine and rubidium leakage depending upon the species used. The rate of leucine leakage shows a small decline below 5 C for two altitudinal variants of Lycopersicon hirsutum Humb. and Bonpl., whereas Lycopersicon esculentum L. showed a marked increase below 5 C. Rubi...
Although leakage through a tracheoesophageal shunt prosthesis is the main cause of prosthesis failure in a laryngectomy patient, this has never been the subject of in vitro evaluation. The aim of this study was to compare three commercially available voice prostheses by comparison of their in vitro leakage patterns, in absence or presence of a biofilm. To compare in vitro leakage patterns, a mo...
PURPOSE The aim of the present study was to study whether patients developing anastomotic leakage after colorectal resections for colorectal cancer have laboratory signs of an altered hemostatic balance in the systemic circulation, preoperatively and postoperatively, causing an impaired healing process. METHODS Patients operated on for colorectal cancer were studied. Seventeen consecutive pat...
Conjugate heat transfer problem of a disc winding in a power transformer is studied using commercial CFD software. The study is done for oil flow, temperature distribution, hot spot location and temperature of the winding, for three different cases: first, no oil leakage past the top washer; second, partial leakage due to a 2 mm gap between the top oil guiding washer and cylindrical pressboard;...
Leakage power consumption plays a significant role in current CMOS technology. International Technology Roadmap for semiconductors reports that leakage power consumption dominates the total chip power consumption as technology advances to nano scale. Most of the battery operated applications such as cell phones, Laptops etc requires a longer battery life, which can be made possible by controlli...
