In this paper, we propose a segment restoration scheme based on network partitioning to enhance the restoration performance and to manage network efficiently. The proposed restoration scheme divides a large network into several small sub-networks. Since most faults can be restored in a partitioned sub-network or AS(Autonomous System), restoration time is reduced obviously. In this paper, we com...

the effect of soil and phanerogam characteristics on bryophytes composition, richness, abundance and functional groups were investigated in order to understand the factors responsible for bryophytes distribution patterns. three different sand dunes were selected: untouched, artificial sod-covered and planted by ammophila. along 10 transects perpendicular to the shore, a total of 142 permanent r...

abstract non-renewable natural resources play an important role in sustainable development of developing countries such as iran. however, since the natural resources should be preserved for future generations, proper use of such resources seems mandatory. women are one of the prime users of natural resources in developing countries. the purpose of this study is to assess the conservational beha...

introduction: this in vitro study investigates the marginal and internal fit of indirect class ii composite restorations. two different processes for chair-side restorations were compared. in group a, the restorations were fabricated using cad/cam technology (cerec, sirona, germany, bernsheim) and in group b they were made by hand (grandioso inlay system, voco gmbh, germany, cuxhaven). methods:...

statement of problem: shear bond strength (sbs) of home and office bleached enamel will be compromised by immediate application of composite restoration. antioxidant agent may overcome this problem. objectives: this in vitro study assessed the effect of green tea extract on shear bond strength of resin composite to in-office and home-bleached enamel. materials and methods: in this experimental ...

conclusions estelite sigma quick composite had wear resistance similar to that of nano- and microfilled composites. estelite flowable composites demonstrated similar wear resistance to that of a posterior composite. results the wear amounts of the composites are as follows in order: estelite sigma quick (1886.9 ± 518.5 μm2), estelite flow quick (2708.9 ± 578.1 μm2), estelite high flow (3206 ± 2...
