Published: October 2015

AbstractThe essential oil extracted by hydrodistillation from Romanian Artemisia annua aerial parts was characterized by GC/MS analysis, which allowed the identification of 94.64% of the total oil composition. The main components were camphor (17.74%), α‐pinene (9.66%), germacrene D (7.55%), 1,8‐cineole (7.24%), trans‐β‐caryophyllene (7.02%), and artemisia ketone (6.26%). The antimicrobial activity of this essential oil was evaluated by determining the following parameters: minimal inhibitory concentration (MIC), minimal bactericidal concentration (MBC), minimal fungicidal concentration (MFC), and minimal biofilm eradication concentration (MBEC). Moreover, the soluble virulence factors were quantified with different biochemical substrates incorporated in the culture media. The reference and resistant, clinical strains proved to be susceptible to the A. annua oil, with MICs ranging from 0.51 to 16.33 mg/ml. The tested essential oil also showed good antibiofilm activity, inhibiting both the initial stage of the microbial cell adhesion to the inert substratum and the preformed mature biofilm. When used at subinhibitory concentrations, the essential oil proved to inhibit the phenotypic expression of five soluble virulence factors (hemolysins, gelatinase, DNase, lipases, and lecithinases). Briefly, the present results showed that the A. annua essential oil contained antimicrobial compounds with selective activity on Gram‐positive and Gram‐negative bacterial strains as well as on yeast strains and which also interfere with the expression of cell‐associated and soluble virulence factors.
Case formulation in personality disordered offenders: Views from the front line
Authors: Brown Susan , Völlm Birgit 
Published: October 2015

AbstractBackgroundCase formulation (CF) is a process that provides a psychological understanding of a person's difficulties and results in an intervention plan to address them. CF may be particularly useful in complex cases; yet the evidence base on its application in forensic settings is limited. Nevertheless, CF is a key part of the UK government's strategy for high‐risk personality disordered offenders. As part of this strategy, probation staff are expected to carry out CF in order to inform interventions for these offenders.Aims/hypothesesThis study sought to access the experience of probation staff of working with personality disordered offenders and their views around their role in the strategy and what challenges and benefits might arise.MethodsThree focus groups were carried out, each with 6–7 probation staff.ResultsFour themes emerged. Firstly, staff reported a lack of personality disorder (PD)‐specific training, and the work that they do with PD offenders is hampered by this. Secondly, probation staff experience difficulties when attempting to obtain help for PD offenders, including diagnostic assessments and treatment for those already diagnosed. Thirdly, the work probation staff currently do with offenders covers similar areas as CF but with a different focus. Fourthly, participants welcomed the prospect of PD‐specific training but were concerned that they should be appropriately supervised and not left to carry out work for which they feel under‐trained.ConclusionsOur findings point towards potential benefits in providing probation staff with PD‐specific training in order to implement the PD offender strategy.Implications for practiceIssues relating to the lack of provision of appropriate treatment and the need for relevant supervision of probation staff conducting CF need to be addressed in order to enhance the successful operation of the strategy.

Palladium Nanoparticles Supported on Titanate Nanobelts for Solvent‐Free Aerobic Oxidation of Alcohols
Authors: Lu Yong‐Ming , Zhu Hai‐Zhou , Liu Jian‐Wei , Yu Shu‐Hong 
Published: October 2015

AbstractThe solvent‐free selective oxidation of alcohols by O2 without any additives has been studied using palladium nanoparticles supported on a titanate nanobelt. The catalysts were prepared by polyol reduction and impregnation with different kinds of supports. They were evaluated in oxidation reactions of benzyl alcohol. The calcined titanate nanobelt was found to be the best support for the solvent‐free Pd‐catalyzed oxidation of alcohols and excellent catalytic activity as well as high selectivity to the corresponding benzaldehyde could be obtained. Moreover, palladium nanoparticles immobilized on the calcined titanate nanobelt could completely suppress the formation of toluene and benzoic acid, an effect that might be caused by the enhanced basic nature and morphology of the support. The catalyst was not only active and selective towards carbonyl compounds, but also recyclable under the oxidation conditions. This catalyst was also applicable for the oxidation of other alcohols.
Optimisation of Potential Boundaries with Dynamic Electrochemical Impedance Spectroscopy for an Anodic Half‐Cell Based on Organic–Inorganic Hybrid Electrolytes
Authors: Smaran Kumar Sai , Joshi Prerna , Vedarajan Raman , Matsumi Noriyoshi 
Published: October 2015

AbstractAdvances in lithium‐ion battery electrolyte materials have created a niche for the evolution of various electrochemical techniques. Appropriate diagnostic techniques to evaluate new electrolytes are of paramount importance, as the conventional techniques lead to prejudiced conclusions. Organic–inorganic hybrid ion gels, employed as electrolytes for the carbon anodic half‐cell, showing discrepancies in its charge discharge profile, were probed for their abnormal charge–discharge behaviour. Dynamic electrochemical impedance spectroscopy (DEIS) was used as a diagnostic tool; inferences were drawn from charge‐transfer resistance values and used as indicators to delimit the potential boundaries for optimum performance of the cells. Identifying the cut‐off potentials through DEIS and subsequent charge–discharge provided clean profiles.

Effect of microwave radiation on the processing of a Cu‐Ni sulphide ore
Authors: Marion Christopher , Jordens Adam , Maloney Conor , Langlois Ray , Waters Kristian E. 
Published: October 2015

AbstractThe need for fine grinding to liberate valuable minerals from low‐grade ores has become a major concern due to the high energy requirements and low energy efficiencies of comminution processes. One method being studied to improve efficiencies is microwave pre‐treatment. Microwaves can selectively heat certain minerals (absorbers) within an ore, causing internal stresses and forming fractures along grain boundaries. Microwave pre‐treatment of an ore containing microwave‐absorbing minerals and microwave‐transparent gangue can significantly reduce grinding energy. However, these improvements must not be detrimental to downstream processing. This work investigated the effects of microwave radiation on the grindability and flotability of a copper/nickel sulphide ore. A reduction in the Bond Work Index of 22 % was observed after microwave pre‐treatment in a 3.0 kW multimodal microwave (2.45 GHz) for 60 s. Although a significant reduction in the required grinding energy was observed, the amount of energy required to treat the sample is significantly higher than the corresponding Bond Work Index reduction, indicating that the process remains some distance from being economically viable. Microwave pre‐treatment also showed beneficial effects on the flotation of the ore. Copper recovery remained constant while nickel recovery increased by 33.6 % after 120 s of microwave exposure at 0.8 kW, and by 34.4 % after a 30 s exposure at 3.0 kW. Higher microwave exposure also showed an increase in concentrate grade and flotation kinetics of both copper and nickel.

Authors: Wang Xue , Guan Buyuan , He Yapeng , Zhang Ye , Cao Yu , Liu Yunling , Qiao Zhen‐An , Huo Qisheng 
Published: October 2015

AbstractIn this paper, we have established a simple and generalizable sprout‐like growth method for the facile synthesis of Janus mesoporous silica nanostructures with organic–inorganic hybrid components by using periodic mesoporous organosilica (PMO) nanoparticles as seeds with mesoporous SiO2 as branches growing on the PMO surface. The morphology of Janus nanostructures with different lengths and numbers of SiO2 branches can be easily controlled by varying the tetraethoxysilane concentration in the synthesis system. The Janus nanostructures are also easily modified with different SO3H and NH2 groups on the SiO2 branches and PMO cores, respectively, and exhibit excellent catalytic performance in the deacetalization–Henry cascade reaction.

Published: October 2015

SummaryIt is a fact that the attention of research community in computer science, business executives, and decision makers is drastically drawn by big data. As the volume of data becomes bigger, it needs performance‐oriented data‐intensive processing frameworks such as MapReduce, which can scale computation on large commodity clusters. Hadoop MapReduce processes data in Hadoop Distributed File System as jobs scheduled according to YARN fair scheduler and capacity scheduler. However, with advancement and dynamic changes in hardware and operating environments, the performance of clusters is greatly affected. Various efforts in literature have been made to address the issues of heterogeneity (i.e., clusters consisting of virtual machines and machines with different hardware), network communication, data locality, better resource utilization, and run‐time scheduling. In this paper, we present a survey to discuss various research efforts made so far to improve Hadoop MapReduce scheduling. We classify scheduling algorithms and techniques proposed in the literature so far based on their addressing areas and present a taxonomy. Furthermore, we also discuss various aspects of open issues and challenges in the scheduling of MapReduce to improve its performance. Copyright © 2015 John Wiley & Sons, Ltd.
