This work examines the suitability of using seashell (Oyster shell), animal bone and Na2CO3 materials as energizers for case hardening of mild steel. A carburizer consisting of charcoal was used for research with sea shell, animal bone and Na2CO3 as energizers. Samples were carburized in fabricated rectangular stainless steel boxes using different percentages of energizers (10, 20, 30, 40, and 50%) respectively. The samples were covered completely in each of the boxes with the mixture of carburizer and energizer placed in the chamber of the furnace. The process was carried out at carburizing temperature of 9500C, soaked for 4, 6, and 8hours and quenched in oil. Twenty samples were further tempered at 2000C for 1hour to relieve the stress built up during quenching. Hardness test, chemical analysis and impact test were carried out on the samples. The hardness values of the carburized mild steel were measured with a micro hardness tester. The results of the study showed that hardness values of the untempered mild steel samples were slightly improved than the tempered samples at carburizing temperature of 9500C and carburizing time of 4, 6 and 8hours. The Impact results revealed that samples carburized at 9500C in seashell energizer for 8hours have the highest impact values of 184 Joules for the tempered samples which are higher than the untempered samples due to increase in toughness resulting from tempering. The results also showed that seashell and animal bones are potential energizers in case carburization of mild steel.
New Medea de Monique Bosco ou la banalisation d’un mythe
Authors: Marcotte Hélène 
Published: November 2013

Hélène Marcotte se penche sur la forme que peut prendre la désacralisation du mythe en littérature en analysant la banalisation du mythe de Médée par le biais d’une réécriture contemporaine : New Medea de l’auteure québécoise Monique Bosco, paru en 1974. Pour ce faire, elle tente de mettre en relief trois éléments qui concourent à la banalisation du mythe : la reprise des principaux mythèmes, ou invariants, du mythe, la spectacularisation du récit et la perte du caractère héroïque des protagonistes, qui s’accompagne d’un affaiblissement de la dimension sacrée dans l’oeuvre.
Représentations de la mort et dualité dans l’oeuvre de Sylvain Trudel
Authors: Thomas Jean-Pierre 
Published: November 2013

L’écrivain québécois Sylvain Trudel met en scène dans plusieurs de ses oeuvres de jeunes personnages qui opposent au monde rigide des adultes une clairvoyance agrémentée d’un brin de naïveté. Cette posture les rend fragiles et susceptibles d’être attaqués par des forces funestes qui prennent régulièrement, chez le romancier et nouvelliste, un visage manifestement puisé à même un fonds mythologique fécond : quand la mort frappe, c’est ici dans un élan d’implacabilité qui donne des impressions de ressemblance avec un Thanatos ou un Belzébuth, mis toutefois au goût du jour. On reconnaît dans cette entreprise de réactualisation la dualité qui, depuis Platon et jusqu’aux confins du christianisme, marque les traits donnés à la mort. Sylvain Trudel a toutefois tenu à nantir les représentations récupérées d’une originalité que l’on reconnaît dans la facture bigarrée des forces auxquelles ses personnages sont confrontés.
The Experimental Design of App Games to Bridge the Gap between Two Generations
Authors: Hou Hsing-yu 
Published: November 2013

AbstractThe increasingly ageing population is an important issue for family relationships. If the human-device interface is well designed, older citizens can manage icons more easily than typing on a keyboard. The authors use the design of experiment method to evaluate the effect of App games. There are 2*2*2=8 combinations in the experiment. The three factors are image size, touch guidelines and degree of complication. The independent variables are gender, age, technology sensitivity and the attitude to risk. The dependent variable is the game score. It is proven that simplicity, clear guidelines and small screen result in better performance. The elderly like big screens but Apps do bot provide this. These results allow App designers to direct development. More attention to the needs of the elderly during the shooting process might also improve interaction between the elderly and youths.
Face Recognition Using Holistic Features and Within Class Scatter-Based PCA
Authors: Wijaya I Gede Pasek Suta , Uchimura Keiichi , Koutaki Gou 
Published: November 2013

AbstractThe Principle Component Analysis (PCA) and its variations are the most popular approach for features clustering, which is mostly implemented for face recognition. The optimum projection matrix of the PCA is typically obtained by eigenanalysis of global covariance matrix. However, the projection data using the PCA are lack of discriminatory power. This problem is caused by removing the null space of data scatter that contains much discriminant information. To solve this problem, we present alternative strategy to the PCA called alternative PCA, which obtains the optimum projection matrix from within class scatter instead of global covariance matrix. This algorithm not only provides better features clustering than that of common PCA (CPCA) but also can overcome the retraining problem of the CPCA. In this paper, this algorithm is applied for face recognition with the holistic features of face image, which has compact size and powerful energy compactness as dimensional reduction of the raw face image. From the experimental results, the proposed method provides better performance for both recognition rate and accuracy parameters than those of CPCA and its variations when the tests were carried out using data from several databases such as ITS-LAB., INDIA, ORL, and FERET.
A Space Filling Algorithm for Generating Procedural Geometry and Texture
Authors: Bourke Paul 
Published: November 2013

AbstractHere we present an algorithm for procedurally generating a range of digital assets including 2 dimensional textures and 2.5 dimensional texture roughness. The approach involves placing shapes randomly, without overlap and with a monotonically decreasing area, within a region on a plane (the 2 dimensional texture). If the process is continued to infinity then the result is space filling thus providing a variable and potentially infinite degree of visual detail. It will be proposed and illustrated that the process is independent of the actual shape being used and as such can find application to a range of texture effects. As a means of generating texture and form procedurally the result has the other desirable property of being fractal, that is, self similar across scales which is characteristic of many packings that occur in nature.

Published: November 2013

AbstractIn the early days of eLearning, there was an awful lot of hype about expected results from eLearning initiatives. One of the biggest was about how much money organizations could save through eLearning. ELearning provides increased opportunities for delivering and taking part in learning, but building and delivering eLearning is typically not as inexpensive as we were once promised. Here are some of the more common costs associated with eLearning: Content development, Course design and development, Project management processes and tools, Authoring and multimedia development tools, Infrastructure, including Learning Management Systems. Although, better training may drive improved performance, many organizations still find themselves needing to reduce the costs of designing, building, and delivering eLearning. The main objective of this paper is discovering how eLearning could cut down the cost for organizations benefiting from Guild's survey.

Authors: Chathuranga Dhanith , Jayaratne Lakshman 
Published: November 2013

AbstractMusical genre classification is put into context by explaining about the structures in music and how it is analyzed and perceived by humans. The increase of the music databases on the personal collection and the Internet has brought a great demand for music information retrieval, and especially automatic musical genre classification. In this research we focused on combining information from the audio signal than different sources. This paper presents a comprehensive machine learning approach to the problem of automatic musical genre classification using the audio signal. The proposed approach uses two feature vectors, Support vector machine classifier with polynomial kernel function and machine learning algorithms. More specifically, two feature sets for representing frequency domain, temporal domain, cepstral domain and modulation frequency domain audio features are proposed. Using our proposed features SVM act as strong base learner in AdaBoost, so its performance of the SVM classifier cannot improve using boosting method. The final genre classification is obtained from the set of individual results according to a weighting combination late fusion method and it outperformed the trained fusion method. Music genre classification accuracy of 78% and 81% is reported on the GTZAN dataset over the ten musical genres and the ISMIR2004 genre dataset over the six musical genres, respectively. We observed higher classification accuracies with the ensembles, than with the individual classifiers and improvements of the performances on the GTZAN and ISMIR2004 genre datasets are three percent on average. This ensemble approach show that it is possible to improve the classification accuracy by using different types of domain based audio features.
The role of loss of control eating in purging disorder
Authors: Forney K. Jean , Haedt‐Matt Alissa A. , Keel Pamela K. 
Published: November 2013

ABSTRACTObjectivePurging Disorder (PD), an Other Specified Feeding or Eating Disorder (APA, 2013), is characterized by recurrent purging in the absence of binge eating. Though objectively large binge episodes are not present, individuals with PD may experience a loss of control (LOC) while eating a normal or small amounts of food. The present study sought to examine the role of LOC eating in PD using archival data from 101 women with PD.MethodParticipants completed diagnostic interviews and self‐report questionnaires. Analyses examined the relationship between LOC eating and eating disorder features, psychopathology, personality traits, and impairment in bivariate models and then in multivariate models controlling for purging frequency, age, and body mass index.ResultsAcross bivariate and multivariate models, LOC eating frequency was associated with greater disinhibition around food, hunger, depressive symptoms, negative urgency, distress, and impairment.DiscussionLOC eating is a clinically significant feature of PD and should be considered in future definitions of PD. Future research should examine whether LOC eating better represents a dimension of severity in PD or a specifier that may impact treatment response or course. © 2013 Wiley Periodicals, Inc.

ABSTRACTObjectiveThis study aimed to assess the concurrent and convergent validity of the Eating in the Absence of Hunger (EAH) questionnaire parent report of child (EAH‐PC) and child self‐report (EAH‐C) with the EAH behavioral paradigm (EAH%) and usual dietary intake.MethodData were obtained at baseline assessment for 117 treatment‐seeking overweight and obese (BMI > 85th percentile) 8‐ to 12‐year old children (53% female, 54% white) and their parents. Children participated in the EAH free access paradigm after a standardized ad libitum meal. Parents and children completed EAH questionnaires, and the children completed three 24 h recalls. EAH External Eating subscale and total scores were assessed.ResultsEAH% was inversely associated with the EAH‐PC total score (p < .04), however, it was not associated with the EAH‐PC External Eating scale, EAH‐C total score or EAH‐C External Eating scale. Daily caloric intake was positively related to both the EAH‐C total score (p < .02) and External Eating subscale (p < .007). Daily caloric intake was inversely related to EAH‐PC total score (p < .05), but was not related to EAH‐PC External Eating subscale or EAH%.DiscussionConcurrent validity was not supported for EAH questionnaires, but convergent validity was supported for EAH‐C and child daily caloric intake. Further research is warranted to assess whether EAH questionnaires and paradigm are measuring different aspects of EAH in treatment‐seeking children. © 2013 Wiley Periodicals, Inc.

CCK8 negatively regulates the TLR9‐induced activation of human peripheral blood pDCs by targeting TRAF6 signaling

Published: November 2013

SummaryPlasmacytoid dendritic cells (pDCs) are specialized in rapid and massive secretion of type I interferon in response to foreign nuclei acids. Combined with their antigen presentation capacity, this powerful functionality enables pDCs to orchestrate innate and adaptive immune responses. Cholecystokinin octapeptide (CCK8) is a potent immunomodulator, whose role in pDCs function is unknown. In this study, we found that two different cholecystokinin receptors, CCK1R and CCK2R, are expressed on human peripheral blood pDCs. Exogenous CCK8 was able to modulate the TLR‐induced activation of pDCs, including phenotypic maturation, IFN‐α synthesis and secretion, and could also regulate the potential of pDCs to induce adaptive immune responses in vitro. CCK8 inhibited TLR9‐induced activation of tumor‐necrosis factor receptor‐associated factor 6, which is an important adapter protein in activation of interferon‐regulatory factor (IRF)5 and IRF7, possibly through CCK2R, by evoking the activity of protein kinase (PK)A and reducing the activity of PKC. All these results indicate that CCK8 can inhibit the TLR9‐induced phenotypic maturation and activation of pDCs, acting through CCK2R by modulating the tumor‐necrosis factor receptor‐associated factor 6 signaling pathways.

Published: November 2013

ABSTRACTPropentofylline (PPF) is a xanthine derivative with pharmacological effects distinct from those of the classical methylxanthines. It depresses activation of microglial cells and astrocytes which is associated with neuronal damage during neural inflammation and hypoxia. The aim of this study was to evaluate whether PPF had the capacity of affecting glial cells behavior during the process of demyelination and remyelination following ethidium bromide (EB) gliotoxic injury. EB injection into the CNS is commonly used as an experimental demyelinating model inducing local oligodendroglial and astrocytic death, which results in primary demyelination, blood–brain barrier and glia limitans disruption and Schwann cells invasion. Sixty Wistar rats were divided into four different groups receiving 10 microlitres of 0.1% EB or 0.9% saline solution into the cisterna pontis and treated or not with the xanthine. PPF treatment was done using 12.5 mg/kg/day by the intraperitonial route for 31 days of the experimental period. The rats were euthanized from 7 to 31 days after EB injection and brainstem sections were collected and processed for light and transmission electron microscopy studies. Results from both groups were compared by using a semi‐quantitative method developed for documenting in semithin sections the extent and nature of remyelination of demyelinating lesions. Results showed that PPF administration after EB injection significantly increased both oligodendroglial and Schwann cell remyelination at 31 days (mean remyelination scores of 3.67 ± 0.5 for oligodendrocytes and 1.27 ± 0.49 for Schwann cells) compared to untreated animals (scores of 3.19 ± 0.57 and 0.90 ± 0.33, respectively).

Published: November 2013

ABSTRACTThis study evaluates the bond strength of dentin prepared with Er:YAG laser or bur, after rewetting with chlorhexidine on long‐term artificial saliva storage and thermocycling. One hundred and twenty human third molars were sectioned in order to expose the dentin surface (n = 10). The specimens were randomly divided in 12 groups according to treatment and aging: Er:YAG laser rewetting with deionized water (LW) and 24 h storage in artificial saliva (WC); LW and 6 months of artificial saliva storage + 12.000 thermocycling (6M), LW and 12 months of artificial saliva storage + 24.000 thermocycling (12M), Er:YAG laser rewetting with 2% chlorhexidine (LC) and WC, LC and 6M, LC and 12M, bur on high‐speed turbine rewetting with deionized water (TW) and WC, TW6M, TW12M, bur on high‐speed turbine + 2% chlorhexidine (TC) and WC, TC and 6M, TC and12M. The specimens were etched with 35% phosphoric acid, washed, and dried with air. Single Bond 2 adhesive was applied and the samples were restored with a composite. Each tooth was sectioned in order to obtain 4 sticks, which were submitted to microtensile bond strength test (µTBS). The two‐way ANOVA, showed no significant differences for the interaction between the factors and for the aging factor. Tukey 5% showed that the LC group had the lowest µTBS. The rewetting with chlorhexidine negatively influenced the bond strength of the preparation with the Er:YAG laser. The artificial saliva aging and thermocycling did not interfere with dentin bond strength. Microsc. Res. Tech. 77:37–43, 2014. © 2013 Wiley Periodicals, Inc.
Current approaches to managing fear of cancer recurrence; a descriptive survey of psychosocial and clinical health professionals

Published: November 2013

AbstractObjectiveFear of cancer recurrence (FCR) is common amongst cancer survivors and help with this problem is the most frequently reported unmet need in this population. This study investigated how FCR is perceived and managed by clinical health professionals (medical and nursing staff) and psychosocial professionals in oncology settings.MethodsClinical health professionals and psychosocial professionals in oncology settings received emailed invitations from their professional organisation to participate in an online survey.ResultsData from 77 clinical health professionals and 64 psychosocial professionals indicate that FCR is perceived as common and challenging to manage. Thirty‐one percent of psychosocial professionals estimated FCR is present in >50% of cancer survivors seen in their practise. Only a minority (21%) of clinical staff reported always referring patients with high levels of FCR to psychosocial support. Strategies for managing FCR differed considerably amongst psychosocial professionals, and most reported that aspects of acceptance and commitment therapy and/or cognitive behaviour therapy were helpful. Greater than 99% of participants were interested in training to help patients manage FCR.ConclusionsFear of cancer recurrence is commonly identified in oncology settings and a common focus of discussion in follow‐up care. However, patients with high levels of FCR are not routinely referred to psychosocial staff, and barriers to referral to psychosocial care should be investigated. The diversity of approaches reported by psychosocial professionals suggests lack of consensus regarding management of FCR, indicating that the development effective, theoretical‐based intervention and evidence‐based intervention for FCR is a matter of priority.

Performance of varifocal lenses using KTa1 − xNbxO3 crystals with response times faster than 2 μs
Authors: Imai T. , Takayama Y. , Miyazu J. , Kobayashi J. 
Published: November 2013

A varifocal lens (previously reported by the authors) made of a single crystal of potassium tantalite niobate (KTa1−xNbxO3, KTN) is characterised by its fast responses and large apertures (∼ 3 mm). Presented is a report on the focus shift performance of this varifocal lens with response times of < 2 μs. To investigate this quick response, a strobe technique was introduced. It was confirmed that the KTN lens changed its lens power in 2 μs as predicted by the theory stating that the lens power is proportional to the square of the applied voltage. The lens power can be controlled from 0 to 0.8 m−1 at a wavelength of 1.06 μm.

New concept on sinusoidal modulation for three‐phase DC/AC converters: analysis and experiments
Authors: Eskandari Bahman , Tavakoli Bina Mohammad , Golkar Masoud Aliakbar 
Published: November 2013

Various modulation schemes have already been developed for conventional three‐phase buck‐type converters such as sinusoidal pulse‐width modulation and space vector modulation (SVM). However, SVM is not applicable to boost‐type converters. This study proposes a new concept on sinusoidal modulation for both buck and boost‐type three‐phase DC–AC converters. A novel optimised modulation technique is introduced by using basic equations of conventional buck and boost. By solving the optimisation problem, pulse widths will be obtained for a given modulation index. The significant point is that the optimisation problem should not be solved for every modulation index because the answer of the optimisation problem obeys a certain pattern. Also, this method has a positive effect on reducing losses, especially in boost‐converters. Analysis and simulations are first introduced for three‐phase boost‐converters, and then is extended to a buck converter. Furthermore, practical verification takes place on two implemented 1 kVA boost and buck‐converters in order to confirm the proposed technique as well as theoretical analysis and simulations. The experiments and simulations both verify the suggested optimised modulation technique.
