Jealousy in the blink of an eye: Jealous reactions following subliminal exposure to rival characteristics
Authors: Massar Karlijn , Buunk Abraham P. , Dechesne Mark 
Published: October 2008

AbstractIn the present experiment it was investigated whether the evaluation of rivals could be an unconscious process, engaged in automatically whenever a rival is present. To this end, participants were subliminally primed with words relating to rival characteristics after which they read a jealousy inducing scenario and their jealousy was assessed. It was hypothesized that for women, their self‐reported mate value would act as a moderator on the effect the rival characteristics would have on jealousy. For men, it was expected that their satisfaction with their current relationship would act as a moderator. The results confirmed the expectations: women with low mate value reported more overall jealousy, but women with high mate value were more jealous after priming with attractiveness words. Men with high relationship satisfaction reported more overall jealousy than men with low relationship satisfaction, and especially after priming with social dominance words.

Discrete Euler processes and their applications
Authors: Vijverberg Chu‐Ping C. , Gray Henry L. 
Published: October 2008

AbstractThis paper introduces discrete Euler processes and shows their application in detecting and forecasting cycles in non‐stationary data where periodic behavior changes approximately linearly in time. A discrete Euler process becomes a classical stationary process if ‘time’ is transformed properly. By moving from one time domain to another, one may deform certain time‐varying data to non‐time‐varying data. With these non‐time‐varying data on the deformed timescale, one may use traditional tools to do parameter estimation and forecasts. The obtained results then can be transformed back to the original timescale. For datasets with an underlying discrete Euler process, the sample M‐spectrum and the spectra estimator of a Euler model (i.e., EAR spectral) are used to detect cycles of a Euler process. Beam response and whale data are used to demonstrate the usefulness of a Euler model. Copyright © 2008 John Wiley & Sons, Ltd.
Pharmacological “cross‐inhibition” of connexin hemichannels and swelling activated anion channels
Authors: Ye Zu‐Cheng , Oberheim Nancyann , Kettenmann Helmut , Ransom Bruce R. 
Published: October 2008

AbstractThe study of ion channels has relied heavily on the use of pharmacological blocking agents. However, many of these agents have multiple effects, which may compromise interpretation of results when the affected mechanisms/pathways mediate similar functions. Volume regulated anion channels (VRAC) and connexin hemichannels can both mediate the release of glutamate and taurine, although these channels have distinct activation stimuli and hemichannels, but not VRAC, are permeable to Lucifer Yellow (LY). It has been reported that some anion channel blockers may inhibit connexin hemichannels. We further examined the effects of classic gap junction/hemichannel blockers and anion channel blockers on these channels. The typical VRAC blockers, NPPB, IAA‐94, and tamoxifen blocked low divalent cation‐induced glutamate and taurine release and LY loading, presumed due to hemichannel opening. The blocking action of these compounds on hemichannels was concentration dependent and fell within the same range where the drugs classically block VRACs. Conversely, carbenoxolone (CBX), the most widely used gap junction/hemichannel blocker, was an effective blocker of VRAC‐mediated glutamate and taurine release, and blocked these channels at similar concentrations at which it blocked hemichannels. The CBX effect on VRACs was verified using astrocytes from connexin 43 knock out (Cx43 KO) animals. In these cells, the hypotonic induced amino acid flux was retained whereas the low divalent cation solution‐induced flux was lost. These results extend our knowledge about “cross‐inhibition” of VRACs and gap junctions/hemichannels by certain pharmacological agents. Given the overlap in function of these two types of channels, great care must be exerted in using pharmacological blockers to identify one channel from the other. © 2008 Wiley‐Liss, Inc.
Experimental study on the effects of blast‐cap configurations and charge patterns on coke descending in CDQ cooling shaft
Authors: Feng Y. H. , Zhang X. X. , Wu M. L. 
Published: October 2008

AbstractThe coke descending behavior in a CDQ cooling shaft is studied experimentally by means of a tracing method with a digital camera. For three different blast‐caps, the law of coke flow is studied under five conditions of coke charge. The experimental results show that, for the sake of the uniformity of the coke burden descending, a blast‐cap with elliptical cross‐section is a better choice than that with circular cross‐section regardless of high or low placement. A coke charge pattern with a flat top burden surface is preferable to that with peak‐valley surface, a double‐peak superior to a one‐peak. Trajectory and average velocity distribution of coke behavior are depend weakly on whether the coke is continuously fed or not as the discharging began. The blast‐caps have local effects on the descending coke and hardly affect whether the cokes flow smoothly or not in the case of coke burden with enough depth. © 2008 Wiley Periodicals, Inc.

Fluid flow and heat transfer of natural convection over upward‐facing, horizontal heated circular disks
Authors: Kitamura Kenzo , Kimura Fumiyoshi 
Published: October 2008

AbstractNatural convective flows induced over upward‐facing, circular disks were investigated experimentally. The test disks were heated with uniform temperatures and their diameters were varied from 20 to 500 mm. The test fluid was air and water at room temperature. The flow fields over heated disks were visualized with dye and smoke. The results showed that the ambient fluid first enters the outer edge of the disk and, then, separates three‐dimensionally from the surface at certain distance downstream of the edge when the Rayleigh numbers exceed certain critical values. The separated flow is gradually distorted and a fully turbulent state is accomplished in the central portion of the disk. It was found that the onset and the pitches of the separation points could be predicted with the Rayleigh numbers. The overall Nusselt numbers of the disks were also measured in a wide range of Rayleigh numbers from 2 × 105 to 3 × 1010. The results showed almost identical Nusselt numbers between air and water. Based on these results, empirical equations for the overall Nusselt numbers were proposed. © 2008 Wiley Periodicals, Inc.

AbstractWe propose to bridge the domains of positive health and leadership. We suggest that a “positive” health model helps explain highly effective leadership. The leader must strive for health and facilitate health in his/her followers. We look at leadership through this new and positive lens, that of “positive” health promotion.

Getting even with one's supervisor and one's organization: relationships among types of injustice, desires for revenge, and counterproductive work behaviors
Authors: Jones David A. 
Published: October 2008

AbstractI tested hypotheses derived from the agent–system model of justice specifying that, among the different types of justice, interpersonal and informational justice explain the most unique variance in counterproductive work behavior (CWB) directed toward one's supervisor, and procedural justice explains the most unique variance in CWB directed toward one's organization. I also tested whether individuals' desires for revenge against one's supervisor and one's organization mediate certain justice–CWB relationships. Results (N = 424) provided considerable support for the study hypotheses, showing that employees tend to direct their CWB toward the source of perceived mistreatment, and that desires for revenge explain part, but not all, of the relationships between some types of injustice and CWB. Implications for theory, research, and practice are discussed. Copyright © 2008 John Wiley & Sons, Ltd.
Development and validation of an objective intra‐organizational career success measure for managers
Authors: Dries Nicky , Pepermans Roland , Hofmans Joeri , Rypens Laura 
Published: October 2008

AbstractThis study aimed to develop and validate a new objective measure of intra‐organizational career success, that is the Managerial Career Success Measure (MCSM). Although there has been a recent emphasis in the careers literature on the subjective career, there is still a need for a valid operationalization of ‘traditional’, objective career success as this construct is still considered relevant by many occupational and national groups; furthermore, many studies continue to use objective career success as a (dependent) variable. With regard to content validity, it appears that the measure that was developed incorporates some elements of the commonly used measures of objective career success (i.e. managerial level, number of promotions, salary and salary progression) while steering clear of some of the issues with each of them separately. Concurrent and discriminant validity were explored by analysing data from three empirical studies that were carried out in a large heterogeneous managerial population (N = 1101). Results indicate that the MCSM displays higher levels of content and construct validity than do other, commonly used measures of objective career success. Copyright © 2008 John Wiley & Sons, Ltd.
SVET study of the corrosion protection of electrodeposited Zn and Zn‐Co‐Fe alloy coated steels
Authors: Lodhi Z. F. , Zhan H. , Mol J. M. C. , Terryn H. , de Wit J. H. W. 
Published: October 2008

AbstractThe scanning vibrating electrode technique (SVET) was applied to study the corrosion resistance of partially coated (Zn and various Zn‐Co‐Fe alloys) and partially exposed steel samples in 10 mM NaCl solution. The sacrificial properties and the protection range decreases with increase in Co content in the alloy. For high Co content in the alloy, the coating becomes more noble to steel and loses its sacrificial protection. The barrier resistance of the coatings increases with the increase in Co content in the alloy coating. Zn‐Co‐Fe alloys with high Co content (i.e., 32 wt% Co and 1 wt% Fe) showed excellent barrier properties due to passivation after dezincification protecting the underlying steel. An intermediate region of compositions can be distinguished in which the coatings provide a good combination of sacrificial and barrier resistance properties and also a reasonable protection range.
Potential high temperature corrosion problems due to co‐firing of biomass and fossil fuels
Authors: Montgomery M. , Vilhelmsen T. , Jensen S. A. 
Published: October 2008

AbstractOver the past few years, considerable high temperature corrosion problems have been encountered when firing biomass in power plants due to the high content of potassium chloride in the deposits. Therefore, to combat chloride corrosion problems co‐firing of biomass with a fossil fuel has been undertaken. This results in potassium chloride being converted to potassium sulphate in the combustion chamber and it is sulphate rich deposits that are deposited on the vulnerable metallic surfaces such as high temperature superheaters. Although this removes the problem of chloride corrosion, other corrosion mechanisms appear such as sulphidation and hot corrosion due to sulphate deposits. At Studstrup power plant Unit 4, based on trials with exposure times of 3000 h using 0–20% straw co‐firing with coal, the plant now runs with a fuel mix of 10% straw + coal. Based on results from a 3 years exposure in this environment, the internal sulphidation is much more significant than that revealed in the demonstration project. Avedøre 2 main boiler is fuelled with wood pellets + heavy fuel oil + gas. Some reaction products resulting from the presence of vanadium compounds in the heavy oil were detected, i.e. iron vanadates. However, the most significant corrosion attack was sulphidation attack at the grain boundaries of 18‐8 steel after 3 years exposure. The corrosion mechanisms and corrosion rates are compared with biomass firing and coal firing. Potential corrosion problems due to co‐firing biomass and fossil fuels are discussed.
The effect of phosphate on MAO of AZ91D magnesium using AC power source
Authors: Wen Q. , Cao F.‐H. , Shi Y.‐Y. , Zhang Z. , Zhang J.‐Q. 
Published: October 2008

AbstractA rapid and convenient anodization technology with AC power source to obtain the MAO films formed on magnesium alloy AZ91D in phosphate bath (base electrolyte + Na3PO4) with or without aluminate and silicate was studied. The corrosion resistance of the anodic films was studied by electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization techniques and the microstructure and composition of films were examined by SEM and XRD. The results show that Na3PO4can promote the occurrence of sparking during the MAO process, while abundant heat generated by sparking might enhance the formation of the glassy phase of the compound when the electrolyte contains the additives of NaAlO2and Na2SiO3simultaneously. The optimized MAO film is ivory‐white smooth by naked eye, while presents porous and microcracks in microscopic scale. The anodic film formed in the alkaline solution with optimized parameters possesses superior corrosion resistance by electrochemical test. The XRD pattern shows that the components of the anodized film consist of MgO, MgAlO2, and MgSiO3. No oxide crystal with P element can be found.

Published: October 2008

AbstractLet G be a connected graph. A routing in G is a set of fixed paths for all ordered pairs of vertices in G. The forwarding index of G is the minimum of the largest number of paths specified by a routing passing through any vertex of G taken over all routings in G. This article investigates the forwarding index of a wrapped butterfly graph, determines the exact value for the directed case, and gives an upper bound for undirected case. © 2008 Wiley Periodicals, Inc.

Matchings in connection with ground delay program planning
Authors: Ball Michael , Dahl Geir , Vossen Thomas 
Published: October 2008

AbstractIn this article we analyze certain matching problems that arise in ground delay program planning. Ground delay programs are air traffic flow management initiatives put in place when airport arrival demand is expected to exceed arrival capacity for an extended length of time, e.g. 4 h. Most of the problems we study can be modeled as assignment problems, where flights are assigned to arrival slots. In the context we analyze, however, these problems have important special structure, which allows us to develop special solution properties. In particular, solutions are measured both in terms of efficiency (delay minimization) and equity (delay distribution). We show that the theory of majorization provides a powerful tool in addressing solution equity. We consider problems with flight deletions and develop special solution properties and parametric methods. © 2008 Wiley Periodicals, Inc. NETWORKS, 2009
A linear‐time algorithm for broadcast domination in a tree
Authors: Dabney John , Dean Brian C. , Hedetniemi Stephen T. 
Published: October 2008

AbstractThe broadcast domination problem is a variant of the classical minimum dominating set problem in which a transmitter of power p at vertex v is capable of dominating (broadcasting to) all vertices within distance p from v. Our goal is to assign a broadcast power f(v) to every vertex v in a graph such that ΣvεVf(v) is minimized, and such that every vertex u with f(u) = 0 is within distance f(v) of some vertex v with f(v)> 0. The problem is solvable in polynomial time on a general graph (Heggernes and Lokshtanov, Disc Math (2006), 3267–3280) and Blair et al. (Congr. Num. (2004), 55–77.) gave an O(n2) algorithm for trees. In this article, we provide an O(n) algorithm for trees. Our algorithm is notable due to the fact that it makes decisions for each vertex v based on “nonlocal” information from vertices far away from v, whereas almost all other linear‐time algorithms for trees only make use of local information. © 2008 Wiley Periodicals, Inc.

Evaluations on the miscibility of the mixtures of poly(2,6‐dimethyl‐1,4‐phenylene oxide) and a copolyester of bisphenol‐A
Authors: Sakar Dolunay , Cankurtaran Ozlem , Karaman Ferdane 
Published: October 2008

AbstractInverse gas chromatography (IGC) was used to analyze the miscibility of binary mixtures of poly(2,6‐dimethyl‐1,4‐phenylene oxide) (PPO) and a copolyester of bisphenol‐A with terephthalic and isophthalic acids (50/50) (PAr) in three compositions. The glass transition temperature (Tg) was determined from the slope change on the retention diagrams of some solvents on the polymers and their binary mixtures. Single Tgs of the mixtures suggested that PAr and PPO are miscible. Separately, IGC data were used to determine the solvent‐independent polymer–polymer interaction parameters of the binary mixtures above their Tgs by means of some methods proposed by several authors. The magnitudes of the interaction parameters and shifting of ester carbonyl peak of PAr on the Fourier transform infrared (FTIR) spectra suggested that these polymers were miscible.

Synthesis of liquid crystalline moiety containing N‐cyclohexylmaleimide copolymers
Authors: Yuksel M. , Canak T. Cakir , Serhatli I. E. 
Published: October 2008

AbstractAtom transfer radical polymerization (ATRP) was applied to copolymerize liquid crystalline acrylate (6‐(4‐cyanobiphenyl‐4′‐oxy)hexyl acrylate) (LC6) monomer and N‐cyclohexylmaleimide (NCMI) monomer. Copolymerization of LC6 and NCMI in the presence of Cu(I)Br/N, N, N′, N′′, N′′‐pentamethyldiethylene‐triamine (PMDETA) catalyst system using anisole as a solvent at 110°C initiated by 2‐bromopropionyl bromide afforded well‐defined copolymers. In addition, free radical polymerization (FRP) was applied using 2,2′‐azodiisobutyronitrile (AIBN) as an initiator in toluene at 70°C for the same monomers. The influences of several factors such as monomer ratio and time on the copolymerization, spectral, and thermal properties of resultant copolymers were investigated. The glass transition temperature and thermal stabilities of the copolymers were increased by increasing the N‐substituted maleimide (N‐cyclohexylmaleimide) content. As a result, thermally stable liquid crystalline alternating copolymers were synthesized by introducing maleimide segments into the polymer. Copyright © 2008 John Wiley & Sons, Ltd.
Triplex protein quantification based on stable isotope labeling by peptide dimethylation applied to cell and tissue lysates
Authors: Boersema Paul J. , Aye Thin Thin , van Veen Toon A. B. , Heck Albert J. R. , Mohammed Shabaz 
Published: October 2008

AbstractStable isotope labeling is at present one of the most powerful methods in quantitative proteomics. Stable isotope labeling has been performed at both the protein as well as the peptide level using either metabolic or chemical labeling. Here, we present a straightforward and cost‐effective triplex quantification method that is based on stable isotope dimethyl labeling at the peptide level. Herein, all proteolytic peptides are chemically labeled at their α‐ and ϵ‐amino groups. We use three different isotopomers of formaldehyde to enable the parallel analysis of three different samples. These labels provide a minimum of 4 Da mass difference between peaks in the generated peptide triplets. The method was evaluated based on the quantitative analysis of a cell lysate, using a typical “shotgun” proteomics experiment. While peptide complexity was increased by introducing three labels, still more than 1300 proteins could be identified using 60 μg of starting material, whereby more than 600 proteins could be quantified using at least four peptides per protein. The triplex labeling was further utilized to distinguish specific from aspecific cAMP binding proteins in a chemical proteomics experiment using immobilized cAMP. Thereby, differences in abundance ratio of more than two orders of magnitude could be quantified.
Study on the addition of nonmetal interstitial atoms to the yttrium lattice: formation of YBx, YCx and YNx alloys
Authors: Soto Gerardo , Moreno‐Armenta Maria G. , Reyes‐Serrato Armando 
Published: October 2008

AbstractYttrium is a rather rare and reactive met al. Due to these characteristics it absorbs important quantities of light atoms in its void spaces. Here, we present a study where B, C and N atoms are gradually incorporated into the octahedral interstices of Y. The idea is to model, by first‐principles calculations in a supercell approach, several stages of nonmetal assimilation in the yttrium lattice. In this case to develop YBx, YCx and YNx alloys. This study is limited to the cubic close‐packed stacking of Y and chemical compositions in the 0 ≤ x ≤ 1 range. We found that the studied alloys become thermodynamically favored. The cohesive energies improve with the addition of the nonmetal atoms. Besides, the cell volume and the bulk modulus vary differently for each kind of added atom. We come upon the fact that the ratio between cohesive energy and cell volume is strikingly better for YNx. We conclude that these alloys permit a remarkable degree of modulation in their properties and electronic structures by means of chemical composition. (© 2009 WILEY‐VCH Verlag GmbH & Co.
