One of the key questions in ecosystem restoration is the choice of the seed material for restoring plant communities. The most common strategy is to use local seed sources, based on the argument that many plants are locally adapted and thus local seed sources should provide the best restoration success. However, the evidence for local adaptation is inconsistent, and some of these inconsistencie...

A variety of esthetic restorative materials are available for restoring primary incisors. Knowledge of the specific strengths, weakness, and properties of each material will enhance the clinician's ability to make the best choice of selection for each individual situation. Intracoronal restorations of primary teeth may utilize resin composites, glass ionomer cements, resin-modified ionomers, or...

wetlands in the lower reaches of songhua river (lrsr), northeast china, are rich in biodiversityand natural resources, which provide crucial staging and wintering habitats for various endangered species.however, in the past five decades, the size of this wetland area has decreased, and its quality has deteriorated because of increased natural and human activities. wetland restoration is critica...

by Sean Borman Multiframe superresolution restoration refers to methods for still image and video restoration from multiple low-resolution, degraded observed images derived from an underlying scene. These methods extend classical single frame image restoration methods by simultaneously utilizing information from multiple observed images to achieve restoration at resolutions higher than that of ...

An injectable material consisting of calcium sulphate mixed with hydroxyapatite was investigated as a possible alternative to autograft in the restoration of bone defects. The material was studied both in vitro in simulated body fluid (SBF) and in vivo when implanted in rat muscles and into the proximal tibiae of rabbits. Variation in the strength and weight of the material during ageing in SBF...

Aim. Study aimed to determine effects of flowable composites as liner on marginal and internal voids in MOD composite restorations with dif ferent gingival levels. Methods. 45 molars were prepared for MOD cavities. Finish line was prepared 1 mm apical to mesial, and 1 mm coronal to the cemento-enamel junction on distal. Teeth were restored with: Solitaire; Solitaire + Revolution; Surefil; Suref...

introduction: microleakage is a major factor affecting the longevity of adhesive restorations. colored compomer is a new restorative material that was specifically designed for the restoration of primary molars in different colors, but their microleakage is unknown. this study was carried out to compare the microleakage of a colored compomer (twinky star) and a conventional compomer (f2000) wit...

Background and Aim: The main goal of root canal treatment is to prevent or treat apical periodontitis. The aim of the present study was to assess the coronal restoration status, root canal filling quality, periapical health condition, and related factors in endodontically treated teeth at the Dental Faculty of Islamic Azad University of Medical Sciences, Tehran, Iran, in 2011-12. Materials and...
