Abstract Background There is limited information on surgical site infections (SSI) and the related antibiotic resistance needed to guide their management prevention in Sierra Leone. In this study, we aimed establish incidence risk factors of SSI among adults attending a tertiary hospital, secondary health facility Freetown, Methods This prospective cohort study designed collect data from adult (18 years or older) patients who attended elective emergency surgeries at two hospitals Freetown...
The temperature distribution is vital to the lifetime and reliability of converter transformer bushings. However, epoxy impregnated paper bushings under a certain current has usually been calculated through two dimensional model, without considering heat convection radiation effects. In this paper, using computational fluid dynamics (CFD) finite element method (FEM) analysis, 3-D electromagnetic-fluid-thermal analysis proposed. With conduction, radiation, bushing simulated according actual...
BACKGROUND With the in-depth development of minimally invasive spine surgery in recent years, robot- and computer-assisted technologies have been increasingly used successfully applied to spinal surgery. MATERIAL AND METHODS We performed a retrospective analysis 60 patients with grade I or II lumbar spondylolisthesis who underwent transforaminal interbody fusion (MIS-TLIF) from January 2017 December 2017. A robot-assisted surgical system was 30 for pedicle screw placement. The other...
With the increase of transmission power in China, heating problem converter transformer resin impregnated paper (RIP) bushings is increasingly serious. In this paper, applying computational fluid dynamics (CFD), using a 3D electromagnetic-fluid-thermal analysis method, and considering heat conduction, convection, radiation effects, temperature field distribution RIP bushing has been simulated; according to simulation results, maximum epoxy above distortion 120°C. Then, verify accuracy rising...
A series of new fluorinated 9,9′-spirobifluorene derivatives (SFs) have been designed and synthesized for organic light-emitting devices (OLEDs). The spatial structure 2,2′,7,7′-tetrakis(2,4-bifluorophenyl)spiro-9,9′-bifluorene was determined by X-ray diffraction analysis. With the different substitution patterns electron-withdrawing groups, such as F CF3, photophysical properties, energy levels thermal stabilities these SFs can be tuned, which is supported density functional studies their...
The underlying mechanism of the antitumor activity Huaier polysaccharide (HP) remains to be explored. present study aimed investigate inhibitory effect HP on hepatocellular carcinoma (HCC) cells, and explore possible mechanisms its anticancer effect. Cell viability was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, while apoptotic nuclear changes were observed using Hoechst 33258 staining. distribution cell cycle apoptosis analyzed flow cytometry, western...
Early and accurate diagnosis of central nervous system infections (CNSIs) is crucial for clinical treatment. Cerebrospinal fluid (CSF) analysis considered the gold standard diagnosis, sensitivity its results directly affects treatment decisions. However, due to physiological differences in CSF composition between ventricles lumbar space, choice sampling site may lead diagnostic discrepancies, including false negatives. This study aims compare samples obtained via external ventricular...
A series of triphenylamine derivatives end-capped with various fluorinated phenyl (TPAF) have been designed and synthesized for the application in organic light-emitting devices (OLEDs). By changing substitution pattern electron-withdrawing groups, such as F CF3, ability hole-transport, energy levels, thermal stability these, TPAF are tuned, which supported by density functional study their geometry electronic structure. can be used either hole-transporters or blue-violet emitters OLEDs....
Extra high-voltage converter transformer resin impregnated paper (RIP) bushing is used as the outlet device of transformer, its safe operation directly related to reliability power system. Under long-term effects high current, strong mechanical stress and abrasion, contact resistance connection structure inside prone deteriorate. When local overheating increases a certain level, insulation performance will decline may lead penetrating discharge. Therefore, it vital develop strategies for...
Objective: The location of chordomas within the base skull and cervical junction prevents complete resection from being achieved. Previous series have shown that stereotactic radiosurgery can be used as a treatment for residual with good overall results. In present study, we reviewed our experience in using gamma knife surgery (GKS) to treat patients chordomas. Methods: Thirty-one underwent June 1996 December 2004. mean age was 40.2 years (range: 8–70 years). There were 20 male 11 females....
For the structural characteristics of power transmission equipment such as bushings, plug-in structure is mostly used for current-carrying connections owing to large size and long distance at high voltage levels. The contact element strip key component structure, carrying combined electrical–thermal effect. Its electrical performance important. In recent years, discharge failures caused by overheating failure have occurred from time time. However, there been relatively few studies on...
Cellulosic ethanol is regarded as a perfect additive for petrol fuels global carbon neutralization. As bioethanol conversion requires strong biomass pretreatment and overpriced enzymatic hydrolysis, it increasingly considered in the exploration of processes with fewer chemicals cost-effective biofuels value-added bioproducts. In this study, we performed optimal liquid-hot-water (190 °C 10 min) co-supplied 4% FeCl3 to achieve near-complete saccharification desirable corn stalk high...
