Implementations of the Taguchi design for the erosive wear of Luffa cylindrica fiber-reinforced epoxy hybrid composite
Authors: Mohanta Niharika , Acharya Samir Kumar 
Published: October 2014

Abstract
The processing, characterization, and wear response of a new class of natural fiber (Luffa cylindrica) hybrid composite are described. Composite laminates were fabricated by using the hand lay-up technique. Composites were made with a total of four piles by varying the number and position of glass layers so as to obtain different stacking sequences. The erosion rates of the composites were evaluated by varying the impingement angle, particle speed, and dose of the impinging particles. An experimental plan based on the Taguchi technique was used to achieve the erosion in a controlled way. The study reveals that the impact velocity is the most significant factor influencing the erosion rate of the hybrid composite.
Critical Metrics and Fundamental Materials Challenges for Renewable Hydrogen Production Technologies
Authors: Miller Eric L. , Peterson David , Randolph Katie , Ainscough Chris 
Published: October 2014

ABSTRACTThe US Department of Energy’s (DOE) Fuel Cell Technologies Office has made significant progress in fuel cell technology advancement and cost reduction. Encouragingly, rollouts of fuel-cell vehicles by major automotive manufacturers are scheduled over the next several years. With these rollouts, enabling technologies for the widespread production of affordable renewable hydrogen becomes increasingly important. Near-term utilization of current reforming and electrolytic processes is necessary for early hydrogen markets, but transitioning to industrial-scale renewable hydrogen production remains essential to the longer term. Central to the long term vision is a portfolio of renewable hydrogen conversion processes, including, for example, the direct photoelectrochemical and thermochemical routes, as well as photo-assisted electrochemical routes. DOE utilizes technoeconomic analyses to assess the long-term viability of these emerging hydrogen production pathways and to help identify key materials- and system-level cost drivers. Sensitivity analysis from the technoeconomic studies will be discussed in connection with the metrics and fundamental materials properties that have direct impact on hydrogen cost. It is clear that innovations in macro-, meso- and nano-scale materials are all needed for pushing forward the state-of-the-art. These innovations, along with specific research and development pathways for advancing materials systems for the renewable hydrogen conversion technologies are discussed.
Operation of Fill‐and‐Draw Reactors Fed with Bisphenol A as Sole Carbon and Energy Source

Published: October 2014

ABSTRACT: While there is ample evidence in the literature that many organic xenobiotics can be biodegraded as sole carbon and energy source by pure batch cultures of selected microorganisms, the same evidence is very limited for continuous or semi‐continuous mixed‐culture processes simulating biological wastewater treatment plants. This study investigates for the first time whether Bisphenol A (BPA) can be removed and used as sole carbon and energy source by mixed microbial cultures in a semi‐continuous process. Four fill and draw bioreactors were inoculated with unacclimated soil and operated at various hydraulic retention times (HRT), in the range of 1.7–4.2 d, using a feed composed solely of BPA (115 mg/l), and mineral salts. At steady‐state, the BPA removal in the four reactors varied in the range 7.5–19% and did not show a significant trend with the HRT. The maximum growth rate on BPA was measured in the range 0.29–1.54 d−1.

Published: October 2014

ABSTRACT: This paper presents the results of a study conducted on the treatment of combined sewer overflows using ferrate (VI) [Fe (VI)]. At a Fe (VI) dose of 0.24 mg/L, total chemical oxygen demand (TCOD), soluble chemical oxygen demand (SCOD), total biochemical oxygen demand (TBOD5), soluble biochemical oxygen demand (SBOD5), total suspended solids (TSS), volatile suspended solids (VSS), total phosphorus (TP), total nitrogen (TN), and soluble TN removal efficiencies of 71, 75, 69, 68, 72, 83, 64, 38, and 36%, respectively, were achieved. Kinetic studies revealed that a contact time of only 15 minutes is sufficient to achieve secondary effluent criteria. An innovative technique of using primary sludge (PS) and thickened waste activated sludge as a source for the in situ synthesis of ferrate was developed. A comparative study of treatment efficiencies achieved by Fe (VI) generated from different sources was done. At 0.1 mg/L dose of Fe (VI) synthesized from PS, TCOD, SCOD, TSS, VSS, TP, and TN removal efficiencies of 60, 62, 63, 67, 30, and 25%, respectively, were achieved.
Laboratory Comparison of Four Iron‐Based Filter Materials for Water Treatment of Trace Element Contaminants
Authors: Allred Barry J. , Tost Brian C. 
Published: October 2014

ABSTRACT: A laboratory investigation provided preliminary comparison of trace element contaminant water treatment capabilities for four iron‐based filter materials. The iron‐based filter materials tested were zero‐valent iron (ZVI), porous iron composite (PIC), sulfur modified iron (SMI), and iron oxide/hydroxide (IOH). Two types of trace element contaminant solutions were tested, one combined As, Cr, and Se (added as AsO43–, CrO42–, and SeO42–, respectively), while the second combined Cd2+, Cu2+, and Pb2+. The laboratory investigation included saturated falling‐head hydraulic conductivity tests, contaminant removal–desorption/dissolution batch tests, and low‐to‐high flow rate saturated solute transport column tests. Hydraulic conductivity test results indicate that all four iron‐based filter materials have sufficient water flow capacity as indicated by saturated hydraulic conductivity values greater than 1 × 10−2 cm/s. Essentially, 100% of each trace element (As, Cd, Cr, Cu, Pb, and Se) was removed by SMI during the contaminant removal portion of the batch tests and during the column tests, while IOH exhibited good removal of each trace element except Se. Results from the contaminant removal portion of the batch tests and from the column tests showed ZVI and PIC were effective in treating Cd, Cr, Cu, and Pb. With the exception of Se adsorption/precipitation onto IOH, the desorption/dissolution portion of the batch tests showed that once As, Cd, Cr, Cu, Pb, or Se are adsorbed/precipitated onto ZVI, PIC, SMI, or IOH particle surfaces, these trace elements are then not readily desorbed or dissolved back into solution.
Internal Control Quality: The Role of Auditor-Provided Tax Services
Authors: De Simone Lisa , Ege Matthew S. , Stomberg Bridget 
Published: October 2014

ABSTRACT
We propose that auditor-provided tax services (tax NAS) improve internal control quality by accelerating audit firm awareness of transactions material to the financial statements. Using data from 2004 to 2012, we find robust evidence that companies purchasing tax NAS are significantly less likely to disclose a material weakness and that this result is not due to auditor independence impairment. A one-standard-deviation increase in tax NAS is associated with approximately a 13 percent decrease in the rate of material weaknesses relative to the base rate. These results are robust to tests addressing endogeneity concerns. Additional cross-sectional analyses reveal expected increased effects of tax NAS on internal control quality (1) after significant operational changes that require changes to the internal control structure, and (2) earlier in the relationship with the financial statement audit firm, when there are fewer established lines of communication between the audit team and client. This paper contributes to the knowledge spillover literature by identifying a mechanism through which tax NAS improve overall financial reporting quality.
The Impact of Multiple Tax Returns on Tax Compliance Behavior

Published: October 2014

ABSTRACT
Tax compliance research has used prospect theory to describe taxpayers' behavior finding that taxpayers with pending payments due (loss frame) report more aggressively than taxpayers with pending refunds (gain frame). Since taxpayers often file multiple returns and prior research has only examined the impact of single returns on compliance behavior, we extend the research by incorporating the element of taxpayers filing multiple returns (state and federal returns). This study compares taxpayers' behavior in a single net refund or single net payment due condition versus a multiple refund (larger refund and smaller payment due) or multiple payments due condition (larger payment due and smaller refund). Using mental accounting theory, the results show that taxpayers' aggressiveness shifts up in a refund position when the refund is presented as multiple returns rather than a single net return. Taxpayers' aggressiveness shifts down when their payment due position is presented as multiple returns rather than a single net return. While the results in the single net return conditions were consistent with prior compliance research, the results in the multiple returns conditions show a shift in taxpayer aggressiveness from prior research where taxpayers were less aggressive in the multiple payment due condition than the multiple refund condition. A path analysis lends insight into these results by finding that taxpayers' compliance behavior in the single net return and multiple returns conditions is driven by their affective reactions to their tax position. These results suggest that prior tax compliance research that has not incorporated multiple returns may be missing an essential element of the decision environment. These results also extend the growing body of accounting research on mental accounting by providing some initial insight into the role of affect on behavior for single versus multiple outcomes.

Published: October 2014

Abstract
Objective—To evaluate the exposure obtained for minimally invasive abdominal organ biopsy (MIOB) from 3 access incisions in cats.
Design—Prospective experimental study and clinical case series.
Animals—6 purpose-bred research cats and 6 feline clinical patients with indications for abdominal organ biopsy.
Procedures—Three 3-cm incisions into the peritoneal cavity were created at different locations along the linea alba in research cats in randomized order. A wound retraction device was inserted in each incision. Ability to exteriorize various abdominal organs to the extent required to reasonably perform a surgical biopsy was recorded, and results were compared among incision sites. On the basis of results obtained, the access incision that provided exposure of the most frequently biopsied abdominal organs was used to perform MIOB in 6 feline clinical patients with various underlying pathological conditions.
Results—On the basis of experiments with research cats, a 3-cm access incision centered midway between the caudal margin of the xiphoid cartilage and the umbilicus was found to provide access for MIOB for most organs. In 5 of 6 clinical patients, all of the organs of interest were biopsied successfully via this incision location, although access to all hepatic lobes and all parts of the pancreas was inconsistent. In 1 cat, conversion to an open approach was performed because a palpable mass was detected in the area of the duodenocolic ligament.
Conclusions and Clinical Relevance—Optimization of access incision location for MIOB allowed biopsy specimen collection from organs of interest to be performed in a minimally invasive manner in cats.
Influence of Placement on Explicit and Implicit Memory of College Students

Published: October 2014

The use of product placement as a marketing communication tool is based on the inclusion of products or brands in the scene where the action is. The use of this tool has benefits for both the producer of the movie, as well as for brands and / or products. There is currently no consensus in the academic world on how to measure the effectiveness of this communication tool. There is scarce scientific evidence in Latin America, and in Chile this format has been used in television programs, and only recently in movies. The objective of this research is to study the influence of placement in movies on explicit memory (unaided recall and brand awareness) and implicit memory (purchase intention) through the implementation of an experiment performed on a sample of 205 Chilean college students, according to the different types of placement in movies: brands as part of the background, used by a main character, and connected with the plot. The results indicate that the higher the degree of integration of the brand with the plot of the film, the higher the probability of stimulating the explicit memory of participants and thereby unaided recall and brand awareness, providing empirical evidence regarding the learning of consumer behavior through placement as a communication tool.El uso del «product placement» como una herramienta de comunicación en marketing, se basa en la inclusión de productos o marcas en el escenario donde se desarrolla la acción. La utilización de esta herramienta presenta beneficios tanto para el productor del largometraje, como también para las marcas y/o productos. Actualmente no existe en el mundo académico un consenso respecto a cómo medir la efectividad de esta herramienta de comunicación. En Latinoamérica existe una escasa evidencia científica, y en Chile, este formato ha sido utilizado en espacios televisivos, y recientemente se está incursionando en el cine. El objetivo de esta investigación es estudiar la influencia del «placement» en las películas sobre la memoria explícita (recuerdo espontáneo y reconocimiento de marca) y memoria implícita (intención de compra) a través de la aplicación de un experimento a una muestra de 205 estudiantes universitarios chilenos, según los distintos tipos de «placement» en las películas: marcas como parte del fondo, usadas por un personaje principal, y conectadas con la historia. Los resultados indican que cuanto mayor es el grado de integración de la marca con la trama de la película, mayor es la probabilidad de estimular la memoria explícita de los estudiantes y con esto el recuerdo y reconocimiento de una marca, aportando evidencia empírica en relación con el aprendizaje de conductas de consumo por medio del «placement» como herramienta de comunicación.
Police de rue, habitants des quartiers populaires et usage de la force. Analyse d'un processus de défiance réciproque
Authors: Boucher Manuel 
Published: October 2014

Dans un contexte de radicalisation de la politique policière en matière de contention et de répression des « zones urbaines sensibles » depuis au moins une décennie, en s’appuyant sur les résultats d’une longue enquête sociologique réalisée conjointement dans des écoles de police et dans des quartiers populaires, cet article analyse la réalité des rapports entre la police et les habitants de ces quartiers. Dans la pratique, à partir de l’étude des représentations, des modes d’action et des interactions de policiers, d’acteurs sociaux et d’habitants de territoires considérés comme dangereux, nous décrivons les processus qui produisent un rapport de défiance et de réification réciproque, interrogeons la socialisation et la mobilisation de l’usage de la force policière et formulons quelques préconisations pour passer d’une « police de guerre » à une « police de paix ».
Quelle contribution des technologies collaboratives à la configuration des organisations ?
Authors: Tran Sébastien 
Published: October 2014

Les technologies collaboratives (réseaux sociaux d’entreprises, plateformes wiki, groupware, etc.) sont souvent considérées comme l’une des plus importantes évolutions dans le monde des affaires. Bien que la perception des managers soit positive dans la plupart des études menées (Andriole, 2010), il n’en demeure pas moins que les effets concrets des technologies collaboratives au sein des organisations restent encore difficiles à cerner. Il convient notamment de s’interroger sur la contribution de ces outils à la formation de configurations organisationnelles spécifiques (Puranam et al., 2012). En effet, des travaux récents ont mis en avant la nécessité d’approfondir la contribution des SI aux configurations des organisations (Deweet et Jones, 2001 ; Zammuto et al., 2007 ; Markus, 2010 ; Pascal, 2012). Ce travail exploratoire confirme que les technologies collaboratives sont des artefacts structurants des configurations organisationnelles et notre étude de cas permet d’en identifier trois types différents.

Abstract
The Wnt-responsive transcription factor T cell factor 1 (Tcf1) is well known for its role in thymic T cell development and the formation of memory CD8+ T cells. However, its role in the initial phases of CD8+ T effector cell formation has remained unexplored. We report that high levels of Wnt signaling and Tcf1 are operational in naive and memory CD8+ T cells, whereas Wnt signaling and Tcf1 were low in effector CD8+ T cells. CD8+ T cells deficient in Tcf1 produce IFN-γ more rapidly, coinciding with increased demethylation of the IFN-γ enhancer and higher expression of the transcription factors Tbet and Blimp1. Moreover, virus-specific Tcf1−/− CD8+ T cells show accelerated expansion in acute infection, which is associated with increased IFN-γ and TNF production and lower viral load. Genetic complementation experiments with various Tcf1 isoforms indicate that Tcf1 dosage and protein stability are critical in suppressing IFN-γ production. Isoforms lacking the β-catenin binding domain are equally effective in inhibiting CD8+ effector T cell formation. Thus, Tcf1 functions as a repressor of CD8+ effector T cell formation in a β-catenin/Wnt-independent manner.

Phenotypic diversity revealed in cattle prion diseases
Up until now, Bovine Spongiform Encephalopathy (BSE) was thought to be caused by just one pathogen, which explained the highly uniform features of the disease in cattle. Unexpectedly, among cattle diagnosed with BSE in France, we found six cases where the disease marker, i. e. the prion protein, had molecular features clearly distinct from those typically found in BSE. Furthermore, two other cases were recently identified in Italy, with features different both from typical BSE and from these six atypical cases in France. Histopathological features in these two Italian cases also strongly suggested that the disease affecting these animals might not have been BSE. Hypotheses on the origin of such atypical cases are being discussed.
Trypanosomose dans un effectif de chiens militaires en Côte d’Ivoire Canine trypanosomiasis in military working dogs in Ivory Coast
Authors: Lamour Thierry , Ulmer Philippe , Watier-Grillot Stéphanie , Ginesta Jacques 
Published: October 2014

En 2001-2002, plusieurs chiens militaires stationnés à Port-Bouet, en Côte d’Ivoire (Afrique), sont décédés brutalement. Chez ces animaux, le parasite Trypanosoma congolense, un des agents de la trypanosomose canine africaine, a été identifié. La trypanosomose à T. congolense évolue en général chez le chien selon un mode aigu. Les manifestations cliniques de cette affection sont peu spécifiques. Le protocole retenu pour aboutir au diagnostic étiologique a été amélioré grâce à l’utilisation de la technique PCR.
La lutte spécifique contre les trypanosomomes repose sur l’utilisation de molécules trypanocides. L’isométamidium (Samorin ® , Trypamidium ® ) a été employé avec succès comme traitement à la dose de 0,5 mg/ kg par voie intra musculaire. Cette molécule est à présent testée à titre prophylactique. La transmission de la trypanosomose canine africaine est principalement assurée par des glossines ou mouches tsé-tsé. Une enquête entomologique réalisée sur place en avril 2003 a permis de capturer 427 mouches, toutes appartenant à l’espèce Glossina palpalis palpalis. Pour lutter contre ces vecteurs, en plus des mesures de piégeage des mouches, les chiens militaires sont traités avec de la deltaméthrine (collier Scalibor ®) et de la perméthrine (Defendog ® spray).
Une introduction au comportement normal et pathologique des psittacidés
Authors: André Jean-Pierre 
Published: October 2014

Cet article décrit les grands axes du comportement normal et du comportement pathologique chez les psittacidés. Rédigé par un clinicien, il est destiné aux vétérinaires encore peu familiarisés avec ce type de patients, présentés pourtant de plus en plus fréquemment en consultation. Il est désormais évident que la captivité est une source fréquente de troubles comportementaux, souvent très difficiles à traiter. Il s’agit de réactions anormales de peur et/ ou d’agressivité, d’émissions excessives de vocalisations, de stéréotypies, de picage, de surtoilettage, ou encore de comportements sexuels déviants. Une formation adaptée des propriétaires de perroquets permettrait de réduire ce type de troubles. Ces derniers devraient apprendre à respecter les aptitudes et le comportement naturel de leurs oiseaux, en se gardant, en particulier, de toute interprétation anthropomorphique.
