Published: December 2011

AbstractPlants respond to ultraviolet stress inducing a self‐defence through the regulation of specific gene family members. The UV acclimation is the result of biochemical and physiological processes, such as enhancement of the antioxidant enzymatic system and accumulation of UV‐absorbing phenolic compounds (e.g. flavonoids). Globe artichoke is an attractive species for studying the protein network involved in UV stress response, being characterized by remarkable levels of inducible antioxidants. Proteomic tools can assist the evaluation of the expression patterns of UV‐responsive proteins and we applied the difference in‐gel electrophoresis (DIGE) technology for monitoring the globe artichoke proteome variation at four time points following an acute UV‐C exposure. A total of 145 UV‐C‐modulated proteins were observed and 119 were identified by LC‐MS/MS using a ∼144 000 customized Compositae protein database, which included about 19 000 globe artichoke unigenes. Proteins were Gene Ontology (GO) categorized, visualized on their pathways and their behaviour was discussed. A predicted protein interaction network was produced and highly connected hub‐like proteins were highlighted. Most of the proteins differentially modulated were chloroplast located, involved in photosynthesis, sugar metabolisms, protein folding and abiotic stress. The identification of UV‐C‐responsive proteins may contribute to shed light on the molecular mechanisms underlying plant responses to UV stress.
Guidelines for identifying and mitigating thermal hazards of sustainable materials
Authors: Morrison Delmar “Trey” , Hart Ryan J. 
Published: December 2011

AbstractSustainable materials and technologies (a.k.a. “green”) are those that are “delivered with progressively less negative impact upon the Earth.” Thermal hazards such as self‐heating, thermal runaway, fires, and explosions may be associated with a particular sustainable material or process technology. Thermal hazards are a result of the interaction between the exothermic reactivity of the material and the processing or storage conditions (e.g., environment, temperature, duration, size, and configuration). These materials and technologies may pose thermal hazards that only become apparent at large‐scale production and storage levels. With the move toward developing sustainable materials and technologies, many potential new hazardous scenarios for established organizations or for start‐up companies may be identified only during final developmental stages. For example, scaling processing up from pilot to full‐scale may lead to large enough material volumes that thermal hazards that were not identified at the pilot level become significant. Another example may be the increased size of stockpiles of materials required for full‐scale operations. This article aims to provide an overview of several sustainable materials and green technology areas with a discussion of the potential thermal hazards presented. The article will provide guidance for identifying potential thermal hazards in systems and for developing successful prevention and mitigation schemes against fires and explosions. © 2011 American Institute of

Influence of spark duration on deflagration characteristics of methane‐air mixtures
Authors: Zhang Qi , Li Wei , Huang Ying , Duan Yun 
Published: December 2011

AbstractDeflagration behavior data of methane/air mixtures for sparks are essential for a detailed quantitative assessment. This article presents the deflagration data of methane/air mixtures for three spark durations: 6.5 μs, 16.1 μs, and 40.6 μs at standard conditions of pressure and temperature. All the presented data were obtained from the experiments conducted in two explosion vessels: the cylindrical one of 5 L volume, and the spherical one of 20 L volume. For the given ignition energy 56 mJ, the maximum deflagration overpressure, the maximum deflagration temperature, the maximum rate of deflagration pressure rise, and the maximum rate of deflagration temperature rise in the 5 L vessel are approximately constant, as the spark durations increases from 6.5 to 40.6 μs. The same conclusion was obtained for the 20 L vessel. Under the same ignition energy of 56 mJ, the deflagration overpressure of methane/air mixture in the 20 L vessel is approximately equal to those in the 5 L vessel, but the deflagration temperature near the wall of 20 L vessel is significantly lower than those near the wall of 5 L vessel. © 2011 American Institute of

Large magneto‐optical effect in low‐temperature‐grown GaCrN and GaCrN:Si
Authors: Zhou Y. K. , Fan P. H. , Emura S. , Hasegawa S. , Asahi H. 
Published: December 2011

AbstractGaCrN layers were grown at 300 and 100 °C by radio‐frequency plasma‐assisted molecular‐beam epitaxy on sapphire substrates. X‐ray diffraction results showed no obvious secondary phase in the GaCrN samples grown at 300 °C with Cr concentration even up to 9%. A very sharp line was found at 356 nm in the photoluminescence spectra below 50 K, which comes from high crystalline quality regions in the GaCrN layers. All the samples grown at low temperatures exhibited ferromagnetic characteristics. Si‐doped GaCrN with Cr concentration of 6% has the largest saturation magnetization. Magnetic circular dichroism (MCD) measurement was performed for these samples at 10 K to investigate magneto‐optical effect. Large magneto‐optical effect was confirmed in the low‐temperature‐grown non‐doped and Si‐doped GaCrN. Zeeman splitting was enhanced by Si‐doping in the low‐temperature‐grown GaCrN (© 2012 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Molekularzytogenetische Methoden und Array-Diagnostik in der Pränatalmedizin
Authors: Westrich V. , Liehr T. 
Published: December 2011

Zusammenfassung
In der pränatalen Diagnostik kommen aktuell neben zytogenetischen Standardverfahren vermehrt molekulare Methoden zum Einsatz. Während die molekulare Zytogenetik im Rahmen der Fluoreszenz-in-situ-Hybridisierungs(FISH)-Technik seit Jahren routinemäßig in der invasiven vorgeburtlichen Diagnostik eingesetzt wird, wird die Array-Diagnostik gerade erst in dieses Feld eingeführt. FISH wird pränatal meist zur Bestimmung der Größe eines Zellmosaiks, zum Mikrodeletionsausschluss oder zur Abklärung von strukturellen Chromosomenaberrationen durchgeführt. Die Array-CGH („comparative genomic hybridization“, komparative genomische Hybridisierung) wird eher zurückhaltend verwendet, zumeist zur weiterführenden Abklärung bei sonographisch auffälligen Feten und zur Bruchpunktbestimmung bei zytogenetisch nachgewiesenen chromosomalen Umbauten. In Zukunft wird die Array-CGH sicher noch weiter an Bedeutung gewinnen, stellt aber bereits jetzt schon eine wertvolle Ergänzung zu den diagnostischen Verfahren der Zytogenetik und der bisher verwendeten molekulargenetischen Methoden dar.
The Value of an Employment-Based Green Card
Authors: Mukhopadhyay Sankar , Oxborrow David 
Published: December 2011

Abstract
The need for and role of highly skilled immigrant workers in the U.S. economy is fiercely debated. Proponents and opponents agree that temporary foreign workers are paid a lower wage than are natives. This lower wage partly originates from the restricted mobility of workers while on a temporary visa. In this article, we estimate the wage gain to employment-based immigrants from acquiring permanent U.S. residency. We use data from the New Immigrant Survey (2003) and implement a difference-in-difference propensity score matching estimator. We find that for employer-sponsored immigrants, the acquisition of a green card leads to an annual wage gain of about $11,860.

Published: December 2011

AbstractThe type and duration of stress stimulation are postulated to affect the expression of the brain derived neurotrophic factor (BDNF) differentially during ontogenetic life. The aim of our study was to investigate the influence of two different stressors, i.e. chronic (15 min daily for 21 days) exposure to the forced swim (FS) test or the high light open field (HL‐OF) test, on the BDNF contained in magnocellular (PVm) and parvocellular (PVp) neurons of the hypothalamic paraventricular (PV) and the supraoptic (SO) nuclei. The immunofluorescence (‐ir) method was used to detect BDNF‐ir cells. The research showed that only the PVp part of the PV in juvenile (P28; P‐postnatal day) control rats had a significantly lower density of BDNF‐ir neurons than that in middle‐aged (P360) control subjects. After chronic FS, a significant decrease in BDNF‐ir cells was observed in the studied hypothalamic nuclei of the juvenile rats, but no changes were noted in the middle‐aged individuals. The PV (PVm, PVp) and the SO nuclei in juvenile rats showed a significantly lower density of BDNF‐ir neurons than the corresponding area of the hypothalamus in middle‐aged rats. However, following the HL‐OF test, the density of BDNF‐ir neurons remained unaltered both in the P28 and the P360 groups. The data suggest that the type of the stressor applied was the factor that differentiated the number of BDNF‐ir cells in the PVm and the SO only in juvenile rats: chronic HL‐OF was more severe than FS. The age of the animals was the main factor that conditioned the BDNF hypothalamic PV (PVm, PVp) and the SO response to FS stimulation. The different density of BDNF‐ir containing cells in the PVp of juvenile versus middle‐aged rats can be explained by a functional, age‐related change in the demand of PVp neurons for BDNF.
How does celebrity meaning transfer? Investigating the process of meaning transfer with celebrity affiliates and mature brands
Authors: Miller Felicia M. , Allen Chris T. 
Published: December 2011

AbstractThe influence of celebrity spokespersons has largely been examined using source models from the communication literature that feature explicit persuasive messages. Alternatively, theorizing by McCracken (1989) offers a more comprehensive explanation based on meaning transfer. Our research elaborates McCracken's model by investigating a cognitive process underlying meaning transfer. Evaluative conditioning procedures are used as the tool to expose this process. To assess celebrity influence as it may operate in the marketplace, well‐known brands and well‐known celebrities are featured. The results support, at the individual level, McCracken's theoretical axiom concerning meaning transfer from celebrity affiliate to brand.

Published: December 2011

AbstractIntestinal ischemia/reperfusion (I/R) is a complex phenomenon that causes destruction of both local and remote tissues. The objective of this study was to investigate the possible participation of oxidized low‐density lipoproteins (oxLDLs) and inducible nitric oxide synthase (iNOS) expression in renal tissue damage after intestinal I/R. The superior mesenteric artery was blocked for 30 minutes, followed by 24 hours of reperfusion. At the end of the reperfusion period, renal tissues were removed; the presence of oxLDL, superoxide dismutase enzyme activity, malondialdehyde levels, and iNOS expression were evaluated. I/R resulted in positive oxLDL staining in renal tissue. Compared with control rats, tissue from the I/R group showed significantly higher malondialdehyde levels and lower superoxide dismutase enzyme activity. Strong and diffuse iNOS expression was present in the I/R group. Our findings support the hypothesis that I/R of intestinal tissue results in oxidative and nitrosative stress and enhances lipid peroxidation in the end organ. These data show that oxLDL accumulates in rat renal tissue after intestinal I/R. Antioxidant strategies may provide organ protection in patients with reperfusion injury, at least by affecting interactions with free radicals, nitric oxide, and oxLDL. This study demonstrates for the first time that oxLDL may play a role in renal tissue damage after intestinal I/R. Antioxidant strategies may be beneficial for protection from reperfusion injury.
Development of a home‐based telehealthcare model for improving the effectiveness of the chronic care of stroke patients

Published: December 2011

AbstractThis study describes the development of an information technology (IT)‐mediated home‐based healthcare model designed to improve the effectiveness of caring for stroke patients who require chronic, home care. This model was evaluated at Kaohsiung Medical Hospital in Taiwan between 2005 and 2008; 84 newly diagnosed stroke patients diagnosed as the chronic covalence stage were enrolled for preliminary testing of this model. These patients required 24‐hour in‐home monitoring of their health status and emergency call service. Over the course of the study, 15 emergency transfers were carried out, and the acute stroke patients were sent to the emergency care within 26 minutes, on average. This system helped physicians, patients, and their families to more efficiently detect the occurrence of recurrent stroke. In addition, we found a statistically significant finding (p < 0.001) that daily blood pressure (BP) monitoring increased from 45.5% in the initial month of the study to 76% after 3–10 months of intervention. Meanwhile, the proportion of patients with an abnormal BP rate decreased from 20.5% in the initial month of the study to 10.9% after 3–10 months of intervention. This suggests that this model helped to improve patient behavior and their ability to care for themselves. This is the first study to develop an IT‐mediated, home‐based healthcare model in Taiwan. This model integrates both healthcare and clinical services and is capable of enhancing the effectiveness of the care provided to patients with chronic diseases, especially those in situations where self‐care is essential for disease management.
Finite-amplitude solutions in the flow through a sudden expansion in a circular pipe
Authors: Sanmiguel-Rojas E. , Mullin T. 
Published: December 2011

AbstractResults of three-dimensional numerical simulations of the flow through a sudden expansion in a pipe are presented. The axisymmetric state is known to be stable over the range of Reynolds numbers studied, but recent experimental results suggest bifurcation phenomena. A resolution of this dichotomy between calculation and experiment is provided using imperfections to promote the nonlinear development of asymmetric steady states. These lose stability to disordered motion and the boundary between the steady and time-dependent flows has been established over a range of parameters. Moreover, disordered flows are found to co-exist with the axisymmetric regime when the disturbance is removed from the flow. Hence we provide direct numerical evidence for multiplicity of solutions for the axisymmetric expansion problem, which may have relevance to pipe flows.
The rise heights of low- and high-Froude-number turbulent axisymmetric fountains
Authors: Burridge H. C. , Hunt G. R. 
Published: December 2011

AbstractWe present the results of an experimental investigation across a broad range of source Froude numbers,$0. 4\leq {\mathit{Fr}}_{0} \leq 45$, into the dynamics, morphology and rise heights of Boussinesq turbulent axisymmetric fountains in quiescent uniform environments. Typically, these fountains are thought to rise to an initial height,${z}_{i} $, before settling back and fluctuating about a lesser (quasi-) steady height,${z}_{ss} $. Our measurements show that this is not always the case and the ratio of the fountain’s initial rise height to steady rise height,$\lambda = {z}_{i} / {z}_{ss} $, varies widely,$0. 5\lesssim \lambda \lesssim 2$, across the range of${\mathit{Fr}}_{0} $investigated. As a result of near-ideal start-up conditions provided by the experimental set-up we were consistently able to form a vortex at the fountain’s front. This enabled new insights into two features of the initial rise of turbulent fountains. Firstly, for$1. 0\lesssim {\mathit{Fr}}_{0} \lesssim 1. 7$the initial rise height islessthan the steady rise height. Secondly, for${\mathit{Fr}}_{0} \gtrsim 5. 5$, the vortex formed at the fountain’s front pinches off, separates from the main body and rises high above the fountain; there is thus a third rise height to consider, namely, the maximum vortex rise height,${z}_{v} $. From our observations we propose classifying turbulent axisymmetric fountains into five regimes (as opposed to the current three regimes) and present detailed descriptions of the flow in each. Finally, based on an analysis of the rise height fluctuations and the width of fountains in (quasi-) steady state we provide further insight into the physical cause of height fluctuations.
IWASAWA THEORY FOR THE SYMMETRIC SQUARE OF A CM MODULAR FORM AT INERT PRIMES
Authors: LEI ANTONIO 
Published: December 2011

AbstractLet f be a modular form with complex multiplication (CM) and p an odd prime that is inert in the CM field. We construct two p-adic L-functions for the symmetric square of f, one of which has the same interpolating properties as the one constructed by Delbourgo and Dabrowski (A. Dabrowski and D. Delbourgo, S-adic L-functions attached to the symmetric square of a newform, Proc. Lond. Math. Soc. 74(3) (1997), 559–611), whereas the other one has a similar interpolating properties but corresponds to a different eigenvalue of the Frobenius. The symmetry between these two p-adic L-functions allows us to define the plus and minus p-adic L-functions à la Pollack (R. Pollack, on the p-adic L-function of a modular form at a supersingular prime, Duke Math. J. 118(3) (2003), 523–558). We also define the plus and minus p-Selmer groups analogous to the ones defined by Kobayashi (S. Kobayashi, Iwasawa theory for elliptic curves at supersingular primes, Invent. Math. 152(1) (2003), 1–36). We explain how to relate these two sets of objects via a main conjecture.

AbstractIn this paper we use an example of Mukai to construct semistable bundles of rank 3 with six independent sections on a general curve of genus 9 or 11 with Clifford index strictly less than the Clifford index of the curve. The example also allows us to show the non-emptiness of some Brill–Noether loci with negative expected dimension.

AbstractAvian schistosomes belonging to the genusAustrobilharzia(Digenea: Schistosomatidae) are among the causative agents of cercarial dermatitis in humans. In this paper, ribosomal and mitochondrial DNA sequences were used to study schistosome cercariae from Kuwait Bay that have been identified morphologically asAustrobilharziasp. Sequence comparison of the ribosomal DNA (rDNA) 28S and 18S regions of the collected schistosome cercariae with corresponding sequences of other schistosomes in GenBank revealed high sequence similarity. This confirmed the morphological identification of schistosome cercariae from Kuwait Bay as belonging to the genusAustrobilharzia. The finding was further supported by the phylogenetic tree that was constructed based on the combined data set 18S-28S-mitochondrial cytochrome oxidase I (mtCO1) sequences in whichAustrobilharziasp. clustered withA. terrigalensisandA. variglandis. Sequence comparison of theAustrobilharziasp. from Kuwait Bay withA. variglandisandA. terrigalensisbased on mtCO1 showed a variation of 10% and 11%, respectively. Since the sequence variation in the mtCO1 was within the interspecific range among trematodes, it seems that theAustrobilharziaspecies from Kuwait Bay is different from the two species reported in GenBank,A.terrigalensisandA. variglandis.
Longevity Risk and Annuity Pricing with the Lee-Carter Model
Authors: Richards S. J. , Currie I. D. 
Published: December 2011

ABSTRACTSeveral important classes of liability are sensitive to the direction of future mortality trends, and this paper presents some recent developments in fitting smooth models to historical mortality-experience data. We demonstrate the impact these models have on mortality projections, and the resulting impact which these projections have on financial products. We base our work round the Lee-Carter family of models. We find that each model fit, while using the same data and staying within the Lee-Carter family, can change the direction of the mortality projections. The main focus of the paper is to demonstrate the impact of these projections on various financial calculations, and we provide a number of ways of quantifying, both graphically and numerically, the model risk in such calculations. We conclude that the impact of our modelling assumptions is financially material. In short, there is a need for awareness of model risk when assessing longevity-related liabilities, especially for annuities and pensions.
