BACKGROUND Covering insertion sites with chlorhexidine impregnated dressings has been proven to be clinically effective in reducing catheter related blood stream infections (CR-BSI). Two chlorhexidine gluconate (CHG)-impregnated dressings are commercially available, a polyurethane foam disk and a film dressing containing a chlorhexidine gluconate-impregnated gel pad. While both have demonstrate...

BACKGROUND Insertion of a ventriculoperitoneal shunt (VPS) for the treatment of hydrocephalus is one of the most common neurosurgical procedures in the UK, but failures caused by infection occur in approximately 8% of primary cases. VPS infection is associated with considerable morbidity and mortality and its management results in substantial cost to the health service. Antibiotic-impregnated (...

In the present work, SBA-15 and SBA-16 ordered mesoporous silicas were synthesized with different morphologies such as fibers, spheres, rods irregular shapes. Copper cerium oxides active phase was introduced by two methods, incipient wetness impregnation solid-state using a ball mill. The obtained catalysts evaluated in CO preferential oxidation reaction (COPrOx). By means of SAXS, XRD, SEM TEM...

The use of continuous fibers reinforced polymeric composites has increased substantially in the last year’s due to their high specific mechanical strength compared other materials. Despite this property, class material is susceptible low, medium, or energy impacts, which can cause severe damage composite laminates. One most serious damages delamination, lead partial total rupture structure. In ...

The internal structure of the suprachiasmatic nucleus (SCN) was studied qualitatively and quantitatively in several hundred rat brains with a variety of methods including several types of Golgi impregnations, Nissl stains, horseradish peroxidase application, and electron microscopy. One suprachiasmatic nucleus has a volume of about 0.068 mm3 and contains close to 8,000 neurons. Dorsomedially, c...

To address the drawback of low thermal conductivity conventional organic phase change materials (PCMs), a paraffin-wax-based composite (PCC) was assembled via vacuum impregnation method, using new type carbon fiber network material as supporting matrix. The sheet (CFS) exhibited structure comprising high-thermal-conductivity fibers, beneficial for enhancing heat transfer properties PCC. sheet-s...

Activated carbon fibers (ACFs) are beneficial for adsorbing harmful gases because of the well-developed micropores on their surface. Usually, physical adsorption by ACFs is limited textural properties. In this study, effect nickel particle catalyst impregnation physicochemical removal nitric oxide (NO) polyimide (PI)-based (PI-ACFs) was investigated. Ni(NO3)2 used as precursor catalysts and imp...

OBJECTIVE To synthesise the available evidence and estimate the comparative efficacy of control strategies to prevent total hip replacement (THR)-related surgical site infections (SSIs) using a mixed treatment comparison. DESIGN Systematic review and mixed treatment comparison. SETTING Hospital and other healthcare settings. PARTICIPANTS Patients undergoing THR. PRIMARY AND SECONDARY OU...

Disposable personal care products are part of modern life, but these could become a biological hazard in case improper disposal. Therefore, our study compared the biodeterioration plant-based woven materials (cotton, linen), animal (wool, leather), disposable hygiene with cellulose fibers (sanitary pads, cosmetic pads), and chemical impregnated (antimicrobial/sanitary wet wipes) using burial te...

A semiconductor scintillation-type gamma radiation detector is discussed in which the gamma-ray absorbing semiconductor body is impregnated with multiple small direct-gap semiconductor inclusions of bandgap slightly narrower than that of the body. If the typical distance between them is smaller than the diffusion length of carriers in the body material, the photo-generated electrons and holes w...
