Authors: Fernandes Célio , Pontes António José , Viana Júlio César , Gaspar‐Cunha António 
Published: March 2016

ABSTRACTThe purpose of this article is to review the research done in the field of mathematical modeling and optimization of the injection‐molding (IM) process. Various papers related to the mathematical description of the filling, postfilling, and plasticating phases of the IM process were assessed, and some recent advances on the IM field are described. In addition, research devoted to the optimization of the IM process based on various techniques is also discussed. These optimization techniques include design of experiments, artificial neural networks, and evolutionary algorithms. The strengths and weaknesses of each approach were discussed. Finally, this paper also discusses the optimization research performed in the IM process regarding some of the specific features associated with the processes such as runner system and cooling channel configurations, process conditions, gate location, and cavity pressure balancing.
Numerical simulations of the effect of ionic surfactant/polymer on oil–water interface using dissipative particle dynamics
Authors: Wang Shuyan , Yang Shanwen , Wang Xu , Liu Yang , Yang Shuren , Dong Qun 
Published: March 2016

AbstractEffects of the ionic surfactant (cetyltrimethylammonium bromide) and polymer (styrene‐maleic acid copolymers) on the oil/water interface are studied using dissipative particle dynamics at the mesoscopic scale. Effects of the water content on equilibrated morphology of the oil/water emulsion are studied with the help of ionic surfactant. In addition, oil/water emulsion has the patterns of the compound emulsifier at the very low and very high water content. The interfacial tension increases, reaches maximum, and then decreases with an increase of water content. Both experiments and simulations show that the inorganic salts can improve the interfacial efficiency of the ionic surfactants, and lower the interfacial tension. The influence of polymer number is studied on their ability to reduce interfacial tension. The distributions of interfacial tension and mean interfacial density are predicted. The lower the interfacial tension and faster oil coalescence are, the more polymers are. In addition, the influence of the polymer on the surfactant aggregation behavior of the oil–water interface is discussed. © 2016 Curtin University of Technology and John Wiley & Sons, Ltd.

Published: March 2016

AbstractBaO‐B2O3‐P2O5 glasses doped with a fixed concentration of Tb3+ ions and varying concentrations of Al2O3 were synthesized, and the influence of the Al3+ ion concentration on the luminescence efficiency of the green emission of Tb3+ ions was investigated. The optical absorption, excitation, luminescence spectra and fluorescence decay curves of these glasses were recorded at ambient temperature. The emission spectra of terbium ions when excited at 393 nm exhibited two main groups of bands, corresponding to 5D3 → 7Fj (blue region) and 5D4 → 7Fj (green region). From these spectra, the radiative parameters, viz., spontaneous emission probability A, total emission probability AT, radiative lifetime τ and fluorescent branching ratio β, of different transitions originating from the 5D4 level of Tb3+ ions were evaluated based on the Judd‐Ofelt theory. A clear increase in the quantum efficiency and luminescence of the green emission of Tb3+ ions corresponding to 5D4 → 7F5 transition is observed with increases in the concentration of Al2O3 up to 3.0 mol%. The improvement in emission is attributed to the de‐clustering of terbium ions by Al3+ ions and also to the possible admixing of wave functions of opposite parities.

Reaction‐based probe for hydrogen sulfite: dual‐channel and good ratiometric response
Authors: Cheng Xiaohong , He Ping , Zhong Zhicheng , Liang Guijie 
Published: March 2016

AbstractWe designed and synthesized a new series of intramolecular charge transfer (ICT) molecules (compounds T1, T2 and T3) by attaching various electron‐donating thiophene groups to the triphenylamine backbone with aldehyde group as the electron acceptor. Based on the nucleophilic addition reaction between hydrogen sulfite and aldehyde, all compounds could act as ratiometric optical probe for hydrogen sulfite and displayed efficient chromogenic and fluorogenic signaling. Upon the addition of hydrogen sulfite anions, probe T3 displayed apparent fluorescent color changes from yellowish‐green to blue, with a large emission wavelength shift (Δλ = 120 nm). T3 responded to hydrogen sulfite with high sensitivity and the detection limit was determined to be as low as 0.9 μM. At the same time, apparent changes in UV–vis spectra could also be observed. By virtue of the special nucleophilic addition reaction with aldehyde, T3 displayed high selectivity over other anions. Copyright © 2016 John Wiley & Sons, Ltd.

The Pharmacokinetics and Pharmacodynamics of Prasugrel and Clopidogrel in Healthy Japanese Volunteers
Authors: Umemura Kazuo , Iwaki Takayuki 
Published: March 2016

AbstractThe dosing regimen of prasugrel adjusted for Japanese patients was compared with that of clopidogrel by analyzing the pharmacokinetics and pharmacodynamics in 40 healthy Japanese subjects in a randomized, single‐blind crossover study. In period 1, the subjects received either 300 mg clopidogrel or 20 mg prasugrel; after a >2‐week interval (period 2), the drug was switched. Blood samples of 36 of the 40 subjects were collected for analysis of pharmacokinetics, pharmacodynamics, and CYP2C19 genotypes. The plasma concentration of the active metabolite of prasugrel increased rapidly and reached its peak 30 minutes postadministration, whereas that of the active metabolite of clopidogrel reached its peak 1 hour postadministration. The mean AUC and Cmax of the active metabolite of clopidogrel, but not those of prasugrel, were CYP2C19 genotype dependent. Prasugrel rapidly inhibited platelet aggregation, reaching its maximum effect 1 hour postadministration. Clopidogrel, on the other hand, showed maximum inhibition 2 hours postadministration. Platelet aggregation inhibition by clopidogrel was significantly lower in the poor‐metabolizer subjects than in the extensive‐metabolizer subjects. Overall, prasugrel inhibited platelet aggregation more rapidly and more effectively in healthy Japanese subjects than was observed for clopidogrel.
The Construal of Midwives by Pregnant Women with a Body Mass Index Greater Than or Equal to 30 kg/m2 (BMI ≥ 30 kg/m2): A Repertory Grid Study
Authors: Hodgkinson Emma L , Smith Debbie M , Hare Dougal Julian , Wittkowski Anja 
Published: March 2016

ObjectiveTo explore the construal of midwives by pregnant women with a body mass index greater than 30 kg/m2 (BMI ≥ 30 kg/m2).MethodTen pregnant women with a BMI ≥ 30 kg/m2 were recruited from antenatal clinics at a maternity hospital in the North West of England. Each participant completed a repertory grid. The participants chose people to match roles including themselves, pregnant women, midwives of different BMIs and hypothetical elements. They also generated psychological constructs to describe them.ResultsPregnant women with a BMI ≥ 30 kg/m2 construed themselves as vulnerable and self‐conscious. Some women endorsed obesity‐related stereotypes for themselves and felt responsible for their weight. The midwife with a BMI 18 < 30 kg/m2 was considered to be most similar to the ideal midwife, while the midwife with a BMI ≤ 18 kg/m2 was construed as having an undesirable interpersonal style. The midwife with a BMI ≥ 40 kg/m2 was often construed as sharing similar experiences to the pregnant women with a BMI ≥ 30 kg/m2, such as struggling with the psychological consequences of a raised BMI. Some women construed the midwife with a BMI 30 < 40 kg/m2 in a positive way, whereas others viewed it as sharing similar feelings about weight as the midwife with a BMI ≥ 40 kg/m2.ConclusionsThe pregnant women with a BMI ≥ 30 kg/m2 in this study described perceptions of themselves and the midwives responsible for their care, which may affect their engagement and satisfaction with services. Pregnant women with a BMI ≥ 30 kg/m2 should be involved in service development activities to ensure the structure of services and the language used by midwives are acceptable and do not confirm weight‐related stereotypes.

Pregnant women with a BMI ≥ 30 kg/m2 construe themselves as vulnerable and self‐conscious and perceive themselves responsible for their weight.
Pregnant women with a BMI ≥ 30 kg/m2 construe midwives with a low BMI as having an undesirable, cold, interpersonal style.
Midwives with a raised BMI are construed as similar to the women, because they share the uncomfortable psychological consequences of a raised BMI.
The nature of pregnant women's construal may affect their engagement and satisfaction with maternity services and midwifery care.
Estimation of quality of service parameters for OFDM–TDMA networks using Markov chains and service curve
Authors: Vieira Flávio H. T. , Costa Victor H. T. , Rocha Flávio G. C. , Ling Lee L. 
Published: March 2016

SummaryThis paper presents a model based on Queueing Theory for Orthogonal Frequency‐Division Multiplexing–Time‐Division Multiple Access (OFDM–TDMA) networks. This network model requires a Markovian model to the traffic processes. Thus, we present a Markov Modulated Fluid Model (MMFM) with autocorrelation function fitting for the network traffic, in order to evaluate the performance of the transmission link in OFDM–TDMA systems. That is, we deduce equations for estimating QoS parameters of OFDM–TDMA systems. The obtained results confirm that the proposed network model is efficient in describing the OFDM based link performance. A novel equation is also introduced for estimating the buffer overflow probability in OFDM–TDMA systems using a proposed network service curve. The computational effort is reduced compared to the Queueing Theory based method of overflow probability estimation. Besides, the results show that the estimates are very close to those obtained by simulations.
Examining the indirect effects of religious orientations on well‐being through personal locus of control
Authors: Osborne Danny , Milojev Petar , Sibley Chris G. 
Published: March 2016

AbstractReligiosity often positively correlates with well‐being. Some orientations towards religion may, however, adversely affect well‐being by decreasing perceptions of personal locus of control—a critical antecedent of mental health. We examined this possibility in a New Zealand‐based national sample of religiously identified adults (N = 1486). As predicted, fundamentalism had a negative indirect effect on life satisfaction, but a positive indirect effect on psychological distress. Conversely, people's intrinsic religious orientation had a positive indirect effect on life satisfaction, but a negative indirect effect on psychological distress. Notably, all four indirect effects were transmitted through personal, but not God, locus of control. These results highlight the diversity of religious orientations and show that religious orientations that deemphasize people's personal locus of control have negative consequences for well‐being.
Three‐dimensional beam‐truss model for reinforced concrete walls and slabs – part 1: modeling approach, validation, and parametric study for individual reinforced concrete walls
Authors: Lu Yuan , Panagiotou Marios , Koutromanos Ioannis 
Published: March 2016

SummaryA three‐dimensional beam‐truss model for reinforced concrete (RC) walls developed by the first two authors in a previous study is modified to better represent the flexure–shear interaction and more accurately capture diagonal shear failures under static cyclic or dynamic loading. The modifications pertain to the element formulations and the determination of the inclination angle of the diagonal elements. The modified beam‐truss model is validated using the experimental test data of eight RC walls subjected to static cyclic loading, including two non‐planar RC walls under multiaxial cyclic loading. Five of the walls considered experienced diagonal shear failure after reaching their flexural strength, while the other three walls had a flexure‐dominated response. The numerically computed lateral force–lateral displacement and strain contours are compared with the experimentally recorded response and damage patterns for the walls. The effects of different model parameters on the computed results are examined by means of parametric analyses. Extension of the model to simulate RC slabs and coupled RC walls is presented in a companion paper. Copyright © 2016 John Wiley & Sons, Ltd.
Bias correction and characterization of climate forecast system re‐analysis daily precipitation in Ethiopia using fuzzy overlay
Authors: Berhanu Belete , Seleshi Yilma , Demisse Solomon S. , Melesse Assefa M. 
Published: March 2016

ABSTRACTKnowledge of spatiotemporal variability of rainfall magnitude, pattern and trend is fundamental for understanding hydrological systems and runoff prediction for both gauged and ungauged catchments. These variables can be derived from rainfall‐monitoring programmes with adequate spatial distribution and temporal coverage. However, rainfall‐gauging stations in most developing countries are distributed sparsely. Remotely sensed rainfall datasets are becoming alternative rainfall data sources for larger area applications and are proven to have adequate spatiotemporal resolutions. Climate forecast system re‐analysis (CFSR) is one such dataset provided by the National Center for Environmental Prediction (NCEP). This dataset captures the rainfall pattern in Ethiopia but with s magnitude bias of over‐ and underestimations. In this study, magnitude bias correction of the CFSR dataset with a linear scaling technique resulted in a rainfall grid of the country with ∼38 km spatial resolution of a 32 year (1979–2010) daily rainfall dataset. For the bias correction, observed annual rainfall from 930 and daily rainfall from 195 rain gauges were used. The study also attempted to understand the space and time variability of the rainfall through the construction of shape, magnitude and composite rainfall regimes for the entire country. The rainfall regimes of the country were developed using the fuzzy overlay technique with multi‐indices of rainfall. The rainfall regimes address the frequency, duration, timing and magnitude variability of rainfall. The performance of the dataset generation and rainfall regime classification was evaluated using Nash–Sutcliffe Efficiency (NSE) and percent bias (PBIAS) values, which were found to be 0.8 and 1.3, respectively.
