Standby Gas Treatment System (SGTS) is one of the engineered safety features installed in BWR and ABWR plants to limit the discharge of radioactivity into the environment during the reactor accident. Kl3 impregnated charcoal (iodized charcoal) filter is used for removing of radioactive iodine species such as molecular iodine and methyl iodide. It is well known that the removal capability of imp...

Fluorine substituents in the phenyl ring of methyl fluorophenyl carbamates and fluorophenyl isocyanates were varied to determine the influence of fluorine substituents on fungal resistance of wood containing them. In southern pine impregnated with methyl fluorophenyl carbamates, increased fluorine substitution of the phenyl ring increased fungal resistance. Methyl pentafluorophenyl carbamate an...

The resistivity of oil impregnated paper will decrease during its aging process. This paper takes paper resistivity as an assessment index to evaluate the insulation condition of oil impregnated paper in power transformer. The feasibility of this method are discussed in two aspects: reliability and sensitivity. Iterative inversion of paper resistivity was combined with finite element simulation...

A floating unit with three pontoons made of epoxy-coated carbon textile reinforced, ultra-high durability concrete (ECF UHDC), mineral impregnated fibre-reinforced UHDC (MCF UHDC) and, as references, steel-reinforced concretes has been designed and installed in the Northern Atlantic. While marine structures steel reinforcement require large cover depths, which cause problems size, cost, environ...

In this study, we entirely replaced petroleum-based bisphenol A (BPA) with unmodified kraft softwood lignin in epoxy resin formulation. Epoxidized was prepared by reacting biobased epichlorohydrin (ECH) made from glycerol, and the formation of epoxide rings confirmed measuring content epoxidized using titration Fourier-transform infrared spectroscopy (FTIR). fully then mixing a curing agent der...

In this research, a method for producing gum tragacanth (GT) fibers is presented. Ribbon type GT of Astragalus Gummifer species were obtained from local production lands. The gum was treated with alkali to increase its process ability, and allowed to stand for a period of time to reach the proper viscosity and/or to "ripen". Samples with different ripening times were prepared and their viscosit...

BACKGROUND Periprosthetic joint infections (PJI) are often treated by two stage exchange with the use of an antibiotic impregnated spacer. Most of the two-stage exchange algorithms recommend the implantation of an antibiotic-impregnated spacer during the first stage for a period of 2-24 weeks before reimplantation of the new prosthesis. For the spacer to have a therapeutic effect, the local ant...

BACKGROUND AND PURPOSE Antibiotic-impregnated cement is used as a spacer or during re-implantation surgery for the treatment of infected total hip arthroplasties. The routine use of antibiotic-impregnated cement during primary or uninfected revision total hip arthroplasty remains controversial. With this meta-analysis of the published literature, we intended to assess efficacy and safety in the...

CONTEXT Central venous catheters impregnated with chlorhexidine and silver sulfadiazine have recently been introduced for the prevention of catheter-related infections. However, there remains some uncertainty regarding the efficacy of these catheters because of conflicting reports in the literature. OBJECTIVE To evaluate the efficacy of chlorhexidine-silver sulfadiazine-impregnated central ve...

BACKGROUND Catheter-related bloodstream infections (CRBSIs) account for the majority of hemodialysis-related infections. There are no published data on the efficacy of the chlorhexidine-impregnated foam dressing at reducing the rate of CRBSI among patients undergoing hemodialysis. DESIGN A prospective, nonblinded, crossover intervention trial to determine the efficacy of a chlorhexidine-impre...
