OBJECTIVES The nature of vascular trauma varies greatly between continents and across time. The aim of this study was to prospectively analyse the demographics, pathology, management and clinical outcomes of vascular injuries in two urban Malaysian hospitals and review of international literature on vascular trauma. From this information, preliminary management and preventive implications will ...

Abstract Water electrolysers are multi-component systems whose performance relies on each part performing its task. A great emphasis has been placed the development of efficient catalyst-coated electrodes, however efficacy underlying substrate itself overlooked. This paper investigates resulting nickel foam electrodes in 1.0 M KOH after being treated various concentrations hydrochloric acid and...

We report a stripping voltammetric method for the detection of aqueous As(III) using Pt macroelectrode or nanoparticle-modified glassy carbon electrode (GCE) which, novelly, is based on underpotential deposition As atoms. The consists pre-concentration reductive step to accumulate ad-atoms onto Pt, followed by linear sweep voltammetry (LSV). It shown that peak improves response at low concentra...

Ruthenium oxide (RuOx) thin films were spin coated by thermal decomposition of alcoholic solutions RuCl3 on titanium foils and subsequently annealed at 400 °C. The effect coating parameters, such as spinning speed, volume, molar concentration the precursor well number deposits, morphology electrochemical performance electrodes was investigated. characterized scanning electron microscopy (SEM) e...

Using classical Taylor series techniques, we develop a unified approach to pricing and implied volatility for European-style options in a general local-stochastic volatility setting. Our price approximations require only a normal CDF and our implied volatility approximations are fully explicit (ie, they require no special functions, no infinite series and no numerical integration). As such, app...

In this work, we introduce the class of Interrupt Timed Automata (ITA), which are well suited to the description of multi-task systems with interruptions in a single processor environment. This model is a subclass of hybrid automata. While reachability is undecidable for hybrid automata we show that in ITA the reachability problem is decidable. More precisely we show that the untimed language o...

Electrochemical reduction is considered as one of the simple and effective methods with respect to CO2 conversion value-added chemicals. With this regard, on study novel catalysts plays a crucial role for overcoming chemical inertness enhance efficiency. In paper, nano Cu based highly efficient electrocatalysts redution are developed by electrochemical deposition from Cu2+ containing electrolyt...

Substitution of ionic platinum is carried out in Co3O4 host synthesized by solution combustion strategy. These Pt substituted spinels characterized XRD show pure crystalline phase without any separated peaks related to Pt/PtOx. Electrochemical OER activities these are investigated cyclic voltammetry, linear sweep voltammetry and chronoamperometry neutral, alkaline neutral buffer electrolytes. L...
