The scientific heritage preserved in Brazilian biological collections has inestimable value. Despite the research on curation and restoration of biological material is regarded as strategic, there is a lack of expertise in these areas in the country. These deficiencies often determine the use of obsolete or even inadequate procedures aimed at the recovery of material for research or exhibition,...

Introdouction: Overhang refers to the extension of restoration material from the cavity. It has an important role in decay, plaque accumulation and periodontal disease, so the aim of this study is determining the frequency of restoration overhang in patients in Anzali, Guilan. Materials and methods: This descriptive cross-sectional study was completed using 293 patients who visited fo...

The aim of this work was to present a small cross-sectional survey of composite restoration clinical attributes associated with choices for replacement. Ninety-four composite fillings selected to be replaced were included in this study. A questionnaire was filled out after each procedure in order to assess the clinical conditions that indicated the restoration replacement (marginal staining, un...

Numerous pits in coastal waters are subject to degraded water quality and benthic habitat conditions, resulting in degraded fish habitat. A pit in Barnegat Bay, New Jersey (USA) was partially filled with dredged sediment to increase flushing, alleviate hypoxia, and enhance benthic assemblages. Restoration objectives were assessed in terms of benthic community parameters and fishery resource occ...

Faults in a Shipboard Power System (SPS) may occur due to material casualties of electrical components or widespread fault due to battle damage. These faults may interrupt supply of electrical energy to loads that are important for proper functioning and survivability of SPS. To improve the reliability of SPS, and thus to enhance survivability of naval ships, automatic service restoration is pe...

Public facility restoration planning traditionally focused on response to natural disasters and hazardous materials accidental releases. These plans now need to integrate response to terrorist actions. Therefore, plans must address a wide range of potential vulnerabilities. Similar types of broad remediation planning are needed for restoration of waste and hazardous material handling areas and ...

Tooth-coloured, resin composite restorations are amongst the most frequently prescribed forms of dental restoration to manage defects in posterior teeth. The attainment of a desirable outcome when placing posterior resin composite restorations requires the clinician to have a good understanding of the benefits (as well as the limitations) posed by this material, together with a sound knowledge ...
