introduction: the aim of the present experimental study was to evaluate the push-out bond strength of dorifill, epiphany and mta-fillapex sealers to root canal dentin in presence and absence of smear layer (sl). methods and materials: sixty human single-rooted teeth were selected and divided into six groups ( n= 10). the canal irrigation protocol in groups 1, 3 and 5 consisted of 2.5% naocl dur...

Using ProModel simulation language, a universal warehouse storage simulation model has been developed. Applications of the model have been executed with success to analyze the storage capacity and rack efficiency of a medium volume, low stock-keeping unit (SKU) warehouse and a medium volume, large SKU warehouse. The model is scaleable and can be modified to simulate any warehouse configuration,...

response to exercise training is different in variable age range, but it has not determined the differences physical response in children, adults and youth. according to this idea, the purpose of present study is a randomized trial to compare the effect of age on physical response in different periods to fitness training in various ages period. 36 participants voluntarily were randomized at thr...

introduction: the aim of this in vitro study was to evaluate the effect of various irrigants on the push-out bond strength of calcium-enriched mixture (cem) cement and mineral trioxide aggregate (mta). methods and materials: a total of 140 dentin disks with a thickness of 1.5±0.2 mm and lumen size of 1.3 mm, were randomly divided into 12 groups ( n =10) and 4 control groups ( n =5). the lumen o...

statement of problem: calcium hydroxide which is commonly used as an intracanal medicament, changes the ph of dentin and periradicular tissues to an alkaline ph. in some clinical situations, endodontic reparative cements like calcium enriched mixture cement are used after calcium hydroxide therapy. however, the alkaline ph may affect the physical properties of this cement. objectives: this stud...

A fully integrated single-ended output pushpush oscillator is realized using an advanced 0.2μm SiGe HBT process. Up to –5 dBm output power is achieved at 180 GHz using a technology with a transition frequency fT of 200 GHz and maximum oscillation frequency fMAX of 275 GHz. Preliminary phase noise measurements show a phase noise of less than –90 dBc/Hz at 1 MHz offset from the 180 GHz carrier.

We now know about both the methods based on the idea of Ford and Fulkerson (which gave rise to Edmonds and Karp’s algorithm, as well as others) in addition to the PUSH-RELABEL method of Goldberg and Tarjan. However, we see that both of these algorithms have a bottleneck procedure; for Ford and Fulkerson’s algorithm, efficiently finding good augmenting paths is a challenge that many have worked ...
