Removable dental prostheses are commonly fabricated using polymethylmethacrylate, a material that does not have favorable mechanical properties and needs reinforcement with particles such as graphene. The aim of this study was to evaluate the flexural strength (FS) Vickers microhardness heat-polymerized polymethylmethacrylate coated graphene-doped stannic oxide (SnO2) thin films thermionic vacu...
It is a familiar observation that different ecotypes of cattle, whether they are distinguished as species, breeds, or strains, show marked contrasts in coat cover. These differences follow the principle, dignified by Wright (1954) as “Wilson’s Rule”, of a gradient from thick, woolly coats in cold climates to short coats with bristly hairs lying sleekly against the skin in hot climates. The cont...
The purpose of the present study was to evaluate the microleakage at the composite-repair interface using different bonding systems. Composite resin specimens (Filtek Z250 - 3M-ESPE) were divided into five groups (n=20) according to the following bonding mechanism: C - control - etching with 35% phosphoric acid; SB1 - etching and application of one coat of Single Bond (3M-ESPE); SB2 - etching a...
Striped jack nervous necrosis virus (SJNNV), a fish nodavirus, is the causative agent of viral nervous necrosis in marine fishes. The fish nodaviruses are divided into four different genotypes based on the nucleotide sequence of the coat protein gene. In the present study, partial coat protein genes of fish nodaviruses were expressed. This allowed the serological relationship among the differen...
Bacillus spp. and Clostridium spp. form a specialized cell type, called a spore, during a multistep differentiation process that is initiated in response to starvation. Spores are protected by a morphologically complex protein coat. The Bacillus anthracis coat is of particular interest because the spore is the infective particle of anthrax. We determined the roles of several B. anthracis orthol...
Background and Aim: Achieving adhesion between restorative materials and dentin as a wet and dynamic surface is an important topic in restorative and especially in conservative dentistry. Adhesion of new dentin bonding systems depends on the formation of hybrid layer and micromechanical retention. Nevertheless, an ideal adhesive system has not yet been introduced .Recent studies reveal an incre...
Compared to typical asphalt mixtures, poroelastic mixtures are characterised by high porosity and flexibility, which desirable for traffic noise reduction. However, the same properties increase risk of debonding from lower layer, is a significant source premature damage. The study investigates factors – tack coat agent, type texture layer have greatest impact on interlayer bonding quality. From...
