Abstrac: In this paper, the mechanical properties of high density polyethylene (HDPE grade 3840) produced by Bandare ImamIran, mixed with the wood and bagasse as fillers with 10-50 % w/w have been studied. The maximum tensile strength was observed at 10% w/w of fillers ratio. The elongation, impact strength and fracture energy were decreased with increasing of fillers ratio while the Young modu...

Fillers temporarily augment deflated or ptotic facial compartments to restore a youthful appearance. Hyaluronic acids predominate the fillers market because of their focal volumization, duration of effect, low incidence of adverse reactions, and reversibility. Being able to properly perform these in-office procedures will ensure safety for patients and provide aesthetically optimal results. Thi...

Neutral polymer bonding agent (NPBA) is one of the most promising polymeric materials, widely used in nitrate ester plasticized polyether (NEPE) propellant as bonding agent. The structure and dynamics of NPBA under different conditions of temperatures and sample processing are comprehensively investigated by solid state NMR (SSNMR). The results indicate that both the main chain and side chain o...

Effect of different fillers on natural rubber compounds was investigated through curing, mechanical properties and morphology studies for improving mechanical performance of rubber articles. In this work, natural rubber blends with Silica as Single-filler compounds, and blends with Silica and Carbon black as Bi-filler compounds were considered. Then, natural rubber blends with Silica, Carbon bl...

Chitosan (CHI), a biocompatible and biodegradable polysaccharide with the ability to provide a non-protein matrix for tissue growth, is considered to be an ideal material in the biomedical field. However, the lack of good mechanical properties limits its applications. In order to overcome this drawback, CHI has been combined with different polymers and fillers, leading to a variety of chitosan-...

The purpose of this study was to investigate the reinforcing effect of short E-glass fiber fillers oriented in different directions on composite resin under static and dynamic loading. Experimental short fiber-reinforced composite resin (FC) was prepared by mixing 22.5 wt% of short E-glass fibers, 22.5 wt% of resin, and 55 wt% of silane-treated silica fillers. Three groups of specimens (n=5) we...

Effects of silane coupling agents with different functional groups such as epoxy, isocyanate and ureide on the electrical and mechanical properties of copper filled electrical conductive adhesives (ECAs) were studied. Copper (Cu) fillers were used as conductive fillers and polyurethane resin was applied as the adhesive material in this study. Significant differences could be observed on the as ...

The decline in religious identification and corresponding increase in the unaffiliated has been one of the most important religious changes in the United Kingdom (UK). The emergence of the “religious nones” is the most obvious sign of continuing secularization and the declining social and cultural relevance of religion. Yet while the religiously-unaffiliated often form the plurality — if not so...

a new three-dimensional unit cell model has been developed for modeling three constituent phases including inclusion, interphase and matrix. the total elastic modulus of nano-composite is evaluated.  numerical results are in good agreement with the previous proposed theoretical modeling. higher matrix and inclusion elastic modulus both can dramatically influence the total elastic modulus.

background: in this study morphological and molecular characterization of acan­thamoeba strains, isolated from dental unit waterlines (duwls) were surveyed and the levels of disinfection achievable in vitro by the application of ozone disinfect­ant to duwls were evaluate. methods: water samples were collected from air-water syringes, cup fillers and tap water before and at the end of the workin...
