Aiming at demonstrating the potential of unidirectional natural fiber-reinforced thermoplastic composites in structural applications, textile flax yarn/thermoplastic polyester composites with variable fiber volume fractions have been manufactured by a filament-winding process followed by a vacuum-assisted compression molding process. The microstructure of the composites shows that the flax fibe...

BACKGROUND/AIM Ventriculoperitoneal shunt infections remain an important problem and result mainlyfrom perioperative colonization of shunt components by skin flora. Antibiotic-impregnated shunts have been designed to prevent such colonization. T'his study evaluates the incidence of shunt infection after the insertion of antibiotic-impregnated shunts in a population of children with hydrocephalu...

Particulated fiber reinforced polymer (FRP) composite pipes encompass unidirectional continuous glass fibers (hoop glass), resin (thermoset vinylester) matrix, chop (discontinuous short fibers), and particulate reinforcement (sand) impregnated into resin. They are categorized based on their nominal diameter, pressure class, stiffness class. Mechanical characteristics of this class materials hav...

In this study two solid supports, silica and florisil, were impregnated with crown ether (dibenzo-18-crown-6) and Fe(III) ions and their efficiency was compared in the adsorption process of As(V) from aqueous solutions. The solid supports were impregnated with crown ether due to their ability to build complexes with positives ions. Fe(III) was used because of As(V) affinity for it. The impregna...

The aim of this study was to determine the effectiveness of antibiotic-impregnated implants in the prevention of bone infection. We used a model of contaminated fracture in goats to evaluate four treatment groups: no treatment, hand-made tobramycin-impregnated polymethylmethacrylate beads, commercially-available tobramycin-impregnated calcium sulphate pellets and commercially-available tobramyc...

In order to visualize the distribution pattern of the neuronal bodies and neurofibrils in the honeybee brain, we adapted a metallic impregnation technique first described for vertebrate nervous system by Ramón y Cajal. The honeybee brain constitution plays a key role in the development of learning and memory capacities. The general characteristics observed in the honeybee brain, stained by meta...

La& Atsirtant Drmanstrotw of Anatomy, in thc Mrdical Drpartmtnt of tht Univrrri/y of Michigan. By far the greater number of all the communications dealing with the ending of nerves in muscle tissues pertain to observations made on muscle tissue impregnated with one or the other of the several gold chloride methods; valuable as such observations have been, they yet leave many of the details more...

Abstract Recycling of carbon fibers is one the upcoming global research topics in composite engineering. This work investigates influence chemical treatment on recovery from fiber reinforced plastic before pyrolysis. The pretreatment was achieved using a zinc chloride/ethanol solution. pyrolysis process conducted sliding furnace. effect such pre-treatment thermal degradation behaviour determine...

Controversy surrounds the role of central venous catheters (CVCs) impregnated with antimicrobial agents in the prevention of catheter-related bloodstream infection (CRBSI). We reviewed the current literature to evaluate the efficacy of antimicrobial-impregnated CVCs for preventing CRBSI. Eleven randomized studies published in article form were identified that included a control group that recei...
