Comparative Enantioseparation of Ketoprofen with Trimethylated α‐, β‐, and γ‐Cyclodextrins in Capillary Electrophoresis and Study of Related Selector–Selectand Interactions Using Nuclear Magnetic Resonance Spectroscopy
Authors: Samakashvili Shorena , Salgado Antonio , Scriba Gerhard K.E. , Chankvetadze Bezhan 
Published: December 2012

ABSTRACTThe enantiomers of ketoprofen were separated by capillary electrophoresis using the (2,3,6‐tri‐O‐methyl)‐derivatives of α‐, β‐, and γ‐cyclodextrin (CyD) as chiral selectors. The affinity pattern of the ketoprofen enantiomers toward these CyDs changed depending on their cavity size. Thus, with hexakis (2,3,6‐tri‐O‐methyl)‐α‐CyD and heptakis (2,3,6‐tri‐O‐methyl)‐β‐CyD, the R enantiomer of the drug migrated first, whereas the enantiomer migration order was reversed in the presence of octakis(2,3,6‐tri‐O‐methyl)‐γ‐CyD. The change in the migration order was rationalized on the basis of changes in the structure of the complexes between the ketoprofen enantiomers and the chiral selectors as derived from nuclear magnetic resonance spectroscopy experiments.

Magnetic Removal of Reactive Black 5 from Wastewater Using Ionic Liquid Grafted‐Magnetic Nanoparticles
Authors: Poursaberi Tahereh , Hassanisadi Mostafa 
Published: December 2012

AbstractDue to the unique chemical properties and therefore wide range of applications, significant amounts of reactive dyes often end up in waste waters and this issue raises the need for more efficient treatment technologies. This work investigates the ability of magnetite nanoparticles functionalized with imidazolium based ionic liquid (IL) as an efficient sorbent for the removal of the Reactive black 5 from wastewater. Fourier transform infrared spectroscopy, X‐ray diffraction, transmission electron microscopy, thermo‐gravimetric analysis, and zeta potential measurement were used to characterize the synthesized nanosorbent. The results showed that under optimal conditions, the dye removal efficiency of the grafted IL is 98.5% after a single run. Regeneration of the used sorbent could be possible and the modified magnetic nanoparticles exhibited good reusability. The isothermal data of RB5 sorption conformed well to the Langmuir model and the maximum sorption capacity of IL@Fe3O4 for RB5 was 161.29 mg g−1. Thermodynamic study indicated that the adsorption is endothermic and spontaneous. The use of such a system can provide fast and efficient removal of the reactive dyes from wastewater by using an external magnetic field.
Hemodynamic variations due to spiral blood flow through four patient‐specific bifurcated stent graft configurations for the treatment of abdominal aortic aneurysms
Authors: Stefanov Florian , McGloughlin Tim , Delassus Patrick , Morris Liam 
Published: December 2012

SUMMARYEndovascular repair is now a recognised procedure for treating abdominal aortic aneurysms. However, post‐operative complications such as stent graft migration and thrombus may still occur. To assess these complications numerically, the correct input boundary conditions, which include the full human aorta with associated branching, should be included. Four patient‐specific computed tomography scanned bifurcated stent grafts (SGs) were modelled and attached onto a full human aorta, which included the ascending, aortic arch and descending aortas. Two of the SG geometries had a twisted leg configuration, while the other two had conventional nontwisted leg configurations. Computational fluid dynamics was completed for both geometries and the hemodynamics assessed. The complexity of the flow patterns and secondary flows were influenced by the inclusion of the full human aorta at the SG proximal section. During the decelerating phase significant recirculations occurred along the main body of all SG configurations. The inclusion of the full human aorta did not impact the velocity contours within the distal legs and there was no difference in drag forces with the SG containing the full human aorta and those without. A twisted leg configuration further promoted a spiral flow formation along its distal legs. Copyright © 2012 John Wiley & Sons, Ltd.
Tungsten Carbide Nanoparticles as Efficient Cocatalysts for Photocatalytic Overall Water Splitting
Authors: Garcia‐Esparza Angel T. , Cha Dongkyu , Ou Yiwei , Kubota Jun , Domen Kazunari , Takanabe Kazuhiro 
Published: December 2012

AbstractTungsten carbide exhibits platinum‐like behavior, which makes it an interesting potential substitute for noble metals in catalytic applications. Tungsten carbide nanocrystals (≈5 nm) are directly synthesized through the reaction of tungsten precursors with mesoporous graphitic C3N4 (mpg‐C3N4) as the reactive template in a flow of inert gas at high temperatures. Systematic experiments that vary the precursor compositions and temperatures used in the synthesis selectively generate different compositions and structures for the final nanocarbide (W2C or WC) products. Electrochemical measurements demonstrate that the WC phase with a high surface area exhibits both high activity and stability in hydrogen evolution over a wide pH range. The WC sample also shows excellent hydrogen oxidation activity, whereas its activity in oxygen reduction is poor. These tungsten carbides are successful cocatalysts for overall water splitting and give H2 and O2 in a stoichiometric ratio from H2O decomposition when supported on a Na‐doped SrTiO3 photocatalyst. Herein, we present tungsten carbide (on a small scale) as a promising and durable catalyst substitute for platinum and other scarce noble‐metal catalysts in catalytic reaction systems used for renewable energy generation.
Real‐time traffic signal control for optimization of traffic jam probability
Authors: Cui Cheng‐You , Shin Ji‐Sun , Miyazaki Michio , Lee Hee‐Hyol 
Published: December 2012

AbstractReal‐time traffic signal control is an integral part of an urban traffic control system. It can control traffic signals online according to variations of traffic flow. In this paper we propose a new method for a real‐time traffic signal control system. The system uses a cellular automaton model and a Bayesian network model to predict probabilistic distributions of standing vehicles, and uses particle swarm optimization to calculate the optimal traffic signals. A simulation based on real traffic data was carried out to show the effectiveness of the proposed CAPSOBN real‐time traffic signal control system using a micro traffic simulator. © 2012 Wiley Periodicals, Inc.

Synthesis of 4,5,6,7‐Tetrahydro‐1H‐indole Derivatives Through Successive Sonogashira Coupling/Pd‐Mediated 5‐endo‐dig Cyclization
Authors: Andreev Ivan A. , Belov Dmitry S. , Kurkin Alexander V. , Yurovskaya Marina A. 
Published: December 2012

AbstractA one‐pot Sonogashira cross‐coupling/5‐endo‐dig cyclization procedure leading to 2‐aryl‐4,5,6,7‐tetrahydroindoles was developed. This short (only two steps from commercially available compounds) sequence avoids harsh conditions and expensive catalysts. Our procedure is highly tolerant to a range of functional groups (amino, nitro, carboxy, cyano, hydroxy, and bromo). A family of 21 tetrahydroindoles was synthesized on a gram scale in a good to excellent yields, which is indicative of the general character and scalability of this reaction. This methodology allows access to indoles bearing miscellaneous substituents at the C2 position (by variation of ArI) and at the nitrogen atom (by variation of RNH2, including chiral moieties).
Side effects of gender‐fair language: How feminine job titles influence the evaluation of female applicants

Published: December 2012

AbstractIn many languages, feminization has been used as a strategy to make language more gender‐fair, because masculine terms, even in a generic function, exhibit a male bias. Up to date, little is known about possible side effects of this language use, for example, in personnel selection. In three studies, conducted in Polish, we analyzed how a female applicant was evaluated in a recruitment process, depending on whether she was introduced with a feminine or masculine job title. To avoid influences from existing occupations and terms, we used fictitious job titles in Studies 1 and 2: diarolożka (feminine) and diarolog (masculine). In Study 3, we referred to existing occupations that varied in gender stereotypicality. In all studies, female applicants with a feminine job title were evaluated less favorably than both a male applicant (Study 1) and a female applicant with a masculine job title (Studies 1, 2, and 3). This effect was independent of the gender stereotypicality of the occupation (Study 3). Participants' political attitudes, however, moderated the effect: Conservatives devaluated female applicants with a feminine title more than liberals (Studies 2 and 3).

Why do we help? World change orientation as an antecedent of prosocial action
Authors: Oceja Luis , Salgado Sergio 
Published: December 2012

AbstractWorld change orientation refers to the extent to which one individual attributes his or her prosocial action to the function of making the world a better place. In Study 1, we developed a scale to measure this world change orientation [world change scale (WCS)] and to analyze its theoretical structure as a distinctive motivational orientation. In Study 2, participants were presented with a situation of need and subsequently given an unexpected opportunity to get involved in prosocial behavior. We then tested the hypothesis that degree of involvement is predicted by WCS when the situation is framed in terms of improving the welfare of the world, but by empathic concern when the situation is framed in terms of improving the welfare of a concrete victim. The results of both studies suggest that WCS refers to a distinct motivational orientation, which affects prosocial behavior above and beyond other motives. Copyright © 2012 John Wiley & Sons, Ltd.

Authors: Vasiliadis H.‐M. , Forget H. , Préville M. 
Published: December 2012

ObjectivesThe aim of this study was to assess whether the association, in a naturalistic setting, between daily hassles and diurnal salivary cortisol differs in the presence of depression and anxiety in older adults.MethodsData were assessed in a large representative community sample of older adults (n = 1760). A multinomial analysis was used to study as an outcome variable: no disorder, depression only, anxiety only and depression and anxiety, as a function of daily hassles and cortisol levels controlling for age, gender and time of saliva collection. Multivariate regression analyses were also carried out to test the association between daily hassles and cortisol levels stratified by depression and anxiety status.ResultsA significant positive association was observed between the number of daily hassles reported and cortisol levels in participants with no depression and no anxiety and in participants with anxiety. Participants without depression and anxiety, and those with depression only, had significant lower cortisol levels later in the day. This was not observed in respondents with anxiety.ConclusionStressors such as daily hassles are associated with cortisol secretion in depression and anxiety in older adults in a large epidemiologic setting.

Non‐point source pollution modelling using Soil and Water Assessment Tool and its parameter sensitivity analysis in Xin'anjiang catchment, China
Authors: Zhai Xiaoyan , Zhang Yongyong , Wang Xuelei , Xia Jun , Liang Tao 
Published: December 2012

AbstractNon‐point source pollution is a key issue in integrated river basin management around the world and has resulted in water contamination, aquatic ecology deterioration and eutrophication. Xin'anjiang catchment is the key drinking water source area for Hangzhou City, China. A promising model (Soil and Water Assessment Tool) was applied to assess the non‐point source pollution and its effect on drinking water. Sensitivity analysis of model parameters was carried out using the Sequential Uncertainty Domain Parameter Fitting 2 sensitivity technique. Water discharge, sediment, total nitrogen and total phosphorus load processes from 2000 to 2010 were simulated, and the spatial distributions of non‐point source pollutants were evaluated at the catchment and administrative country levels. The results show that the hydrological parameters of the Soil and Water Assessment Tool were dominantly sensitive for non‐point source pollution simulation, including CN2, RCHRG_DP, ALPHA_BF, SOL_AWC, ESCO and SOL_K and the characteristic parameters of sub‐basins (viz. HRU_SLP and SLSUBBSN). Also, water quality parameters (viz. CH_EROD, NPERCO, RSDCO and PPERCO, PHOSKD, etc.) have a significant effect on nutrients. The model performance was very satisfactory, especially for runoff, sediment and total phosphorus simulation. The non‐point source pollutant load increased from 2001 to 2010 in the whole catchment. Total nitrogen load increased from 3428 tons (0.59 ton km−2) to 7315 tons (1.25 ton km−2), and total phosphorus load increased from 299 tons (0.05 ton km−2) to 867 tons (0.15 ton km−2). The contribution of rice land was the largest, accounting for nearly 95%, followed by tea garden (3.56%), winter wheat (1.37%), forest (0.07%) and grassland (0.02%). Moreover, She County and Xiuning County contributed more than half of the non‐point source pollutants. This study was expected to provide a method and reference for non‐point source pollution quantification and to support water quality management implementation in China.

Field assessment of surface water–groundwater connectivity in a semi‐arid river basin (Murray–Darling, Australia)

Published: December 2012

AbstractIn semi‐arid and arid river basins, understanding the connectivity between rivers and alluvial aquifers is one of the key challenges for the management of groundwater resources. The type of connection present (gaining, losing‐connected, transitional and losing‐disconnected) was assessed at 12 sites along six Murray–Darling Basin river reaches. The assessments were made by measuring the hydraulic head in the riparian zone near the rivers to evaluate if the water tables intersected the riverbeds and by measuring fluid pressure (ψ) in the riverbeds. The rationale for the latter was that ψ will always be greater than or equal to zero under connected conditions (either losing or gaining) and always lesser than or equal to zero under losing‐disconnected conditions. A mixture of losing‐disconnected, losing‐connected and gaining conditions was found among the 12 sites. The losing‐disconnected sites all had a riverbed with a lower hydraulic conductivity than the underlying aquifer, usually in the form of a silty clay or clay unit 0.5–2 m in thickness. The riparian water tables were 6 to 25 m below riverbed level at the losing‐disconnected sites but never lower than 1 m below riverbed level at the losing‐connected ones. The contrast in water table depth between connected and disconnected sites was attributed to the conditions at the time of the study, when a severe regional drought had generated a widespread decline in regional water tables. This decline was apparently compensated near losing‐connected rivers by increased infiltration rates, while the decline could not be compensated at the losing‐disconnected rivers because the infiltration rates were already maximal there.
