having observed the costly failures of different cutoff walls, that had been constructed according to the mix design specified by reputable consultants in iran, a research programme was conducted to study the effects of constituent materials on the properties of plastic concrete. the main properties, such as compressive strength, biaxial and triaxial strains, permeability, and modulus of elasti...

Contact between a slider and bit patterned media (BPM) is investigated using finite element analysis. The effect of contact conditions and material properties at the interface between slider and disk on plastic deformation and temperature is studied. In addition, the planarization of bit pattern media on temperature and plastic deformation is investigated for different filler materials. It is f...

UNLABELLED A cluster of 3 facial Mycobacterium chelonae infections occurred after cosmetic dermal filler injections at a plastic surgery clinic. Pulsed-field gel electrophoresis showed that M chelonae isolated from the clinic tap water were identical to the patient wound isolates. Review of injection procedures identified application of nonsterile ice to the skin prior to injection as a possibl...

An approach for modelling thermo-mechanical responses in a 3D arc welding process is developed using the Smoothed Particle Hydrodynamics (SPH) method. It is demonstrated for a simple arc welding configuration by using full three-dimensional elastoplastic analysis. The flow pattern of the filler material and the resulting plastic strain distribution are analysed. The effect of welding speed on t...

The goal of this article is to present a brief background of biofilms and how they pertain to plastic surgery. Of particular interest are how biofilms affect breast prosthesis and their subsequent complications. The authors also present information on how biofilms are involved in soft-tissue filler complications. After a brief review of the pathophysiology of biofilms and their effect on plasti...

In spite of their popularity in fulfilling aesthetic requirements, plastic brackets still present some disadvantages because of their low elastic modulus, decreased fracture toughness, and reduced wear resistance. Fibre-reinforced composites are well established in dentistry and consist of a polymer matrix in which reinforcing fibres are embedded. Stress is transferred from the polymer matrix t...

There has been an increased global demand for dermal filler injections in recent years. Although hyaluronic acid-based dermal fillers generally have a good safety profile, serious vascular complications have been reported. Here we present a typical case of skin necrosis following a nonsurgical rhinoplasty using hyaluronic acid filler. Despite various rescuing managements, unsightly superficial ...

the effect of the filler content and the different type of wood flour on the mechanical properties of polyethylene- date palm wood flour (dpwf) composite which are gathered from date palm tree annual pruning was studied. the different types of dpwf were stem, leaf and the mixture of stem and leaf. composites were made at 45, 60 and 75 % by weight filler contents. the particle size was 25-40 mes...

Energy dispersive X-ray spectroscopy microanalysis (EDX), scanning electron microscopy (SEM), and Archimedes' Principle were used to determine the characteristics of inorganic filler particles in five dental alginates, including Cavex ColorChange (C), Hydrogum 5 (H5), Hydrogum (H), Orthoprint (O), and Jeltrate Plus (JP). The different alginate powders (0.5 mg) were fixed on plastic stubs (n = 5...
