One of the serious damages of tremendous earthquakes is the damage to bridges as the major components in an    arterial road network, as relief operation is interrupted following cutting roads. Regardless of the magnitude and severity of an earthquake, other factors are also important in the strength and seismic performance of concrete bridges. Freezing-thawing cycles are among the factors, whi...

The article presents the results of scientific research on negative impact fixed denture structures tissues oral cavity and gastrointestinal tract in patients with chronic gastritis.
 relevance work lies fact that orthopedic treatment not only eliminates aesthetic defects, restores impaired function dentoalveolar system, but also has a significant preventive value for prevention diseases.&...

OBJECTIVES The aim of this survey was to determine how a sample of dentists working in general dental practice in the UK sought to restore the mouths of patients who had shortened dental arches (SDAs). STUDY DESIGN A survey was conducted over a period of six months on four commercial dental laboratories. Cases of SDAs comprising the anterior teeth and 2 to 4 premolars were examined; dental pr...

BACKGROUND The effect of hydroxyapatite coating of dental implants is controversial. The long-term fate of hydroxyapatite-coated implants has been the subject of some criticism. PURPOSE The aim of this retrospective study was to assess the clinical outcome of hydroxyapatite-coated cylindrical root-form endosseous Impladent dental implants (LASAK Ltd, Prague, Czech Republic) during a six-year ...

Long-span cable-stayed bridges often have a design service life of more than hundred years, during which they may experience multiple earthquake events and accumulate seismic damage if are located in seismic-prone regions. Earthquake occurrence is discretely randomly distributed over the cycle long-span bridge causes sudden drops structural performance instead yearly fixed degradation. This stu...

this paper presents a new bridge management system (j-bms). it is integrated with a concrete bridge rating expert system that can be used to evaluate the serviceability of existing concrete bridges. the proposed j-bms not only evaluates the performance of bridges, but also offers a rehabilitation strategy based on a combination of maintenance cost minimization and quality maximization. in this ...

BACKGROUND The rehabilitation of an anterior tooth space presents a confronting situation. Several modalities are presently available to address the challenge of an immediate replacement of a missing anterior tooth. These include a removable temporary acrylic prosthesis or resin-bonded bridges. Fibre-Reinforced Composite (FRC) bridges are preferable if they are fixed and if a cost-effective too...

Functional yield is a term used to describe the percentage of dies on a wafer that are not affected by catastrophic defects. Within the interconnect these defects are usually caused by particle contamination and are divided into bridging defects, which join adjacent wires and cuts, which result in broken wires. Functional yield is therefore determined by the geometry of the routing channels, ho...

http://www.tandfonline.com/doi/pdf/10.1080/15732479.2012.670250 Abstract Railway bridges currently encounter the challenges of increasing the load capacity while the environmental sustainability should be achieved. However, it has been realized that the environmental assessment of railway bridges has not been integrated into the decision making process, the standard guideline and criterion is s...

Many researches have been currently conducted on the effects of fault distance on structures revealing that their seismic response can differ according to their distance from the fault. Suspension bridges due to their long period and high flexibility can be more sensitive to this phenomenon, especially in vertical vibration. Since the engineers tend to use longer spans, the length factor should...
