Novel compliant flooring systems are a promising approach for reducing fall-related injuries in older adults based on evidence of substantial force reduction during simulated falls on the hip and minimal influence on balance and mobility. In this study we observed force and acceleration attenuation of up to 80% provided by these products relative to a padded carpet during simulated head impacts.

Due to their positive technical properties, such as high chemical resistance and mechanical durability, epoxy resins are moving into more and more deployment areas. Significant applications in the construction industry are coatings for industrial flooring, concrete restoration, corrosion proofing, adhesives for tiles, and joint mortar. Unfortunately, the growing use of these products is also co...

Revision rates of total hip arthroplasty have decreased after introducing total hip arthroplasty (THA) using ceramic component, since ceramic components could reduce components wear and osteolysis. The fracture of a ceramic component is a rare but potentially serious event. Thus, ceramic on polyethylene articulation is gradually spotlighted to reduce ceramic component fracture. There are a few ...

UNLABELLED Emissions of volatile organic compounds (VOC) and semivolatile organic compounds (SVOC) from materials for flooring installation (primer, screed, adhesive, floor covering) were measured by means of emission test chambers and cells over a time period of at least 28 days at 23 degrees C, 50% relative humidity and an area specific air flow rate of q = 1.25 m(3)/m(2) h. Single components...

The aim of this study was to quantify reaerosolization of microorganisms caused by walking on contaminated flooring to assess the risk to individuals accessing areas contaminated with pathogenic organisms, for example, spores of Bacillus anthracis. Industrial carpet and polyvinyl chloride (PVC) floor coverings were contaminated with aerosolized spores of Bacillus atrophaeus by using an artist a...

Background: Metal ceramic restorations are highly popular and are used for most of the crown and bridge restorations made today. Aims: To evaluate the translucency and fracture strength of two all-ceramic and traditional metal ceramic crowns. Materials and Methods: Thirty crowns of similar size and shape were constructed to fit a standard brass die. Ten crowns were manufactured from each of the...

To systematically review the randomized controlled trials (RCTs) and compare the survival rates and complications of all-ceramic fixed dental prostheses (FDPs) with those of metal-ceramic FDPs. Eligible studies were retrieved in relevant electronic databases from their inception to June 8th, 2016. Then, quality of the included studies was assessed using Cochrane Collaboration’s tool. Heterogene...

OBJECTIVES Our study aimed to examine not only the incidence but also the impact of noise from two types of total hip replacement articulations: ceramic-on-ceramic and ceramic-on-polyethylene. METHODS We performed a case-controlled study comparing subjective and objective questionnaire scores of patients receiving a ceramic-on-ceramic or a ceramic-on-polyethylene total hip replacement by a si...

We present a case of a 71-year-old woman with unexplained instability of her total hip arthroplasty 12 years after implantation due to loosening of the ceramic component of a sandwich ceramic in polyethylene liner. She experienced in total 2 dislocations in 6 months. These events occurred without fracture of the ceramic liner. Sandwich ceramic liners were introduced with the idea of combining t...
