Accréditation-habilitation dans l'enseignement supérieur : de la distinction à la sanction
Authors: Agulhon Catherine 
Published: November 2013

L’évaluation est aujourd’hui au cœur de la gouvernance d’universités autonomes. L’Agence d’évaluation de la recherche et de l’enseignement supérieur (AERES), agence externe créée en 2007, a élaboré une procédure complexe d’évaluation intégrée qui mobilise les acteurs de l’université. L’analyse des rapports d’évaluation produits ces dernières années par l’AERES sur les masters permet de relever les critères retenus qui recouvrent les attendus de l’administration et donc les transformations des conceptions de l’enseignement universitaire. Attractivité des formations, partenariat avec le monde économique, performances en termes de taux organisent ces évaluations. En conséquence, sont renforcés la hiérarchisation et le classement des disciplines et des établissements, leur mise en concurrence.
Apprendre à philosopher à l'école primaire : une « propédeutique philosophique » ?
Authors: Agostini Marie , Mallet Jeanne 
Published: November 2013

Face à un enseignement problématique de la philosophie en classe de terminale et à l’appel à l’instauration d’une « propédeutique philosophique » (Jamet, 1990), des pratiques philosophiques s’invitent aujourd’hui à l’école primaire. Mais ces pratiques peuvent-elles vraiment prétendre constituer une propédeutique philosophique selon les exigences de l’enseignement de la philosophie en classe de terminale ? Pour traiter cette question, nous nous sommes basées sur la matrice philosophique de Michel Tozzi (1993), appuyée entre autres par les travaux de Galichet (1996) et de Léonardy (1993). Nous avons mis en place une expérimentation dans une classe de CM2 afin de vérifier si une pratique philosophique comme la discussion à visée philosophique (DVP) y répondait. Cet article se propose d’en faire un compte-rendu.
Genetic Variation and Phytotoxin Production among Cylindrocladium. Quinqueseptatum Isolates of Hevea Brasiliensis and Eugenia Carryophyllata

Published: November 2013

Cylindrocladium quinqueseptatum (Boedijn & Reitsma 1950) is one of the major plant pathogenic fungi that infects a wide range of plants in humid tropics. The prevailing strains in Sri Lanka cause the foliage and shoot blight diseases and severe defoliation of Hevea brasiliensis (rubber) and Eugenia carryophyllata (clove). The isolates obtained from rubber and clove plants growing in Rathnapura district, in Sabaragamuwa province and Kalutara district, in Western province were evaluated for their toxin activity on hosts and genetic characterization was done using random amplified polymorphic DNA Polymerase Chain Reaction (RAPD-PCR grouping). The analysis of the results using ‘Wilcoxon signed-rank test’ revealed no correlation among the isolates based on their host or geographical origins. But a relationship was observed between the toxin activity and the RAPD grouping of the isolates. The time course experiment reveled that the minimum toxin activity recorded after three days of inoculation and maximum toxin activity was recorded after nine days of inoculation in Modified Fries Medium (MFM) for all the isolates. Based on the toxin activity and genetic characterization data, the isolates were categorized into two groups. The close genetic relationship (similarity index = 0.731) and high toxin activity were shown by one group of isolates obtained from cloves grown in Rathnapura with other two groups of isolates obtained from rubber grown in Kalutara. This observation suggests that C. quinqueseptatum isolated from clove grown in Rathnapura can be a potential pathogen on rubber.DOI: http://dx.doi.org/10.4038/josuk.v7i0.4237J. Sci. Univ.

Pretreatments and Cold Storage on the Quality of Minimally Processed Ambarella (Spondias Dulcis L.) and the Mixed Load of Ambarella and Pineapple (Ananas Comosus (L.) Merr)
Authors: Daranagama A. , Ediriweera S. , Abeywickrama K. 
Published: November 2013

Minimally processed ambarella (Spondias dulcis L.) and the mixed load of ambarella and pineapple (Ananas comosus (L.) Merr) stored at 5-7°C for seven days were evaluated for variation in physico-chemical, sensory and microbiological quality. Samples were treated with sodium chloride, calcium chloride, sodium chloride + calcium chloride, ascorbic acid, citric acid, chitosan or distilled water (control) and packed in polystyrene packages before storage. Pretreatments did not have a significant effect on the physico-chemical properties [titratable acidity (TA), total soluble solids (TSS) and pH] when compared to the control. Sensory attributes such as appearance, colour, odour, flavour, taste and overall acceptability generally declined with time but were within acceptable limits by the end of seven-day storage period. The microbial counts (total plate count and yeast and mould count) for all treatments except for the control were within safe-to-consume limits and Salmonella was not detected in any of the samples by the end of storage period. As pretreatments tested had no significant effect on physico-chemical or sensory properties and maintained low microbial counts, minimally processed ambarella and mixed load of ambarella and pineapple processed this way could be recommended for sale at supermarket chains with cold storage facility as a value added product.DOI: http://dx.doi.org/10.4038/josuk.v7i0.4433J.

Occurrence and Species Diversity of Ground-Dwelling Worker Ants (Family: Formicidae) in Selected Lands in the Dry Zone of Sri Lanka
Authors: Dias R.K. Sriyani , Kosgamage K.R.K. Anuradha 
Published: November 2013

Ants are an essential biotic component in terrestrial ecosystems in Sri Lanka. Worker ants were surveyed in six forests, uncultivated lands and, vegetable and fruit fields in two Districts of the dry zone, Anuradhapura and Polonnaruwa, from November, 2007 to October, 2008 by employing several sampling methods simultaneously along five, 100 m transects. Soil sifting, litter sifting, honey-baiting and hand collection were carried out at 5 m intervals along each transect. Twenty pitfall traps were set up throughout each site and collected after five hours. Air and soil temperatures, soil pH and soil moisture at each transect were also recorded. Use of several sampling methods yielded a higher value for species richness than just one or two methods; values for each land ranged from 19 – 43 species. Each land had its own ant community and members of Amblyoponinae, Cerapachyinae, Dorylinae, Leptanillinae and Pseudomyrmecinae were recorded for the first time from the dry zone. Previous records of 40 species belonging to 23 genera in 5 subfamilies for the Anuradhapura District are updated to 78 species belonging to 36 genera in 6 subfamilies. Seventy species belonging to thirty one genera in 9 subfamilies recorded from the first survey of ants in Polonnaruwa lands can be considered a preliminary inventory of the District; current findings updated the ant species recorded from the dry zone to 92 of 42 genera in 10 subfamilies. Consequent to this sum, the estimate of ant diversity of Sri Lanka rises to 202 species in 64 genera while 12 subfamilies remain unchanged.DOI: http://dx.doi.org/10.4038/josuk.v7i0.6233J. Sci. Univ.

Free groups of interval exchange transformations are rare
Authors: Dahmani François , Fujiwara Koji , Guirardel Vincent 
Published: November 2013

We study the group IET of all interval exchange transformations. Our first main result is that the group generated by a generic pairs of elements of IET is not free (assuming a suitable irreducibility condition on the underlying permutation). Then we prove that any connected Lie group isomorphic to a subgroup of IET is abelian.
Additionally, we show that IET contains no infinite Kazhdan group. We also prove residual finiteness of finitely presented subgroups of IET and give an example of a two-generated subgroup of IET of exponential growth that contains an isomorphic copy of every finite group and which is therefore not linear.
An in vitro Comparison of Marginal Accuracy in Temporary Crowns
Authors: Umer Fahad , Adnan Samira , Raza Khan Farhan 
Published: November 2013

ABSTRACTPurposeTo compare the marginal accuracy of temporary crownsin vitro, using two autopolymerizing temporary crown materials.Materials and MethodsPolyethyl methacrylate and bis-acryl composite were used to make 15 temporary crowns each, on an ivorine mandibular first molar, prepared as to receive a porcelain-fused-to-metal (PFM) crown. Matrices were made of polyvinyl siloxane impressions of a lower typodont arch. After crowns were fabricated, margins of the crowns were trimmed under magnification. Afterwards, margins of prepared tooth and crowns were marked. Each tooth-crown assembly was then observed under microscope (4×). With digital images of each surface, gap between margins of crown and preparation margin was measured in millimeters using computer software, after calibration. Two examiners made the measurements. Independent samples t-test and one-way ANOVA with Bonferroni post hoc analysis were applied to determine the mean marginal gap.ResultsBis-acryl composite crowns exhibited 0.2 mm (SD ± 0.11) mean gap with greatest discrepancy at buccal margins. Mean gap with polyethyl methacrylate crowns was 0.3 mm (SD ± 0.17) with buccal and mesial margins exhibiting the greatest marginal discrepancy, at α <0.001.ConclusionBoth materials did not exhibit ideal marginal accuracy, but temporary luting cement film thickness would compensate for the gap observed in the margins of bis-acryl composite crowns.How to cite this articleAdnan S, Khan FR, Umer F.

Published: November 2013

ABSTRACTMedical imaging technologies involve from X-rays to more advanced imaging modalities like computerized tomography (CT) and magnetic resonance imaging (MRI). These new technologies are able to provide detailed three-dimensional (3D) pictures of areas of interest and therefore valuable data for diagnosis and therapeutic management. The construction of a physical model using this data provides numerous advantages like better visualization of complex anatomic areas, pretreatment surgical practice and enhanced communication and patient education. The following paper describes a case report of a large periapical lesion involving upper anterior teeth requiring periapical surgery. The use of rapid prototyping technology aided in the accurate diagnosis and the precise measurements of the size and location of the lesion and its subsequent management.How to cite this articleRamachandran A, Khan SIR.

MAD About “The Raven”
Authors: Eddings Dennis W. 
Published: November 2013

Abstract
“MAD About ‘The Raven’” examines the eleven times MAD magazine uses “The Raven” as a vehicle of parody either against something external to the poem or to parody Poe and/or his most famous work. The first part of the article looks at how MAD uses “The Raven” to attack such things as advertising, shady business dealings, and Ronald Reagan. The second half focuses on MAD's parody of “The Raven” itself, revealing that poem's underside of absurdity through an analysis of Bill Elder's illustrations. Copies of some of those illustrations help illuminate the point.

Published: November 2013

Background: Wait times in cancer diagnosis and treatment may significantly affect a patient’s treatment outcome, prognosis and quality of life. The purpose of this study was to capture wait time intervals for patients with prostate cancer treated with radiotherapy (RT) at the Odette Cancer Centre, Toronto, Ontario, Canada and to compare patients diagnosed in a rapid diagnostic unit (RDU) versus the usual community referral process.Methods: Patients agreed to participate in the study during their RT planning sessions. A semi-structured interview and chart abstraction was conducted to record key wait time milestones.Results: A total of 87 patients participated in the study: 44 RDU patients and 43 community patients. The median overall wait time intervals from suspicion of prostate cancer to RT was 138 and 183 days, respectively (p = 0.046). There were statistically significant differences observed for other key wait time intervals favouring the RDU cohort: suspicion to decision-to-treat (DTT; p = 0.012), urologist visit to diagnosis (p = 0.0094), diagnosis to DTT (p = 0.018), and diagnosis to treatment (p = 0.016). Risk category and Gleason sum was independently predictive of longer intervals from diagnosis to DTT.Interpretation: Wait time intervals from suspicion to treatment are significantly shorter for prostate cancer patients in 2011 to 2012 than in 2003 when patients were diagnosed and referred in the community setting. A prostate-specific RDU further reduced a number of key wait time intervals supporting more multidisciplinary RDUs for common diseases. Further work needs to be done to identify why delays are occurring and to develop new processes to minimize delays.
Assessment of Antibiotic Prophylaxis Prescribing Patterns for TURP: A Need for Canadian Guidelines?
Authors: Lawson Keith A. , Rudzinski Jan K. , Vicas Ingrid , Carlson Kevin V. 
Published: November 2013

Background: While antibiotic prophylaxis is recommended to all patients undergoing transurethral resection of prostate (TURP), little data exist regarding prescribing patterns of urologists prior to this procedure. Here, we sought to determine real-world antibiotic prophylaxis prescribing patterns at a high volume Canadian institution and determine compliance rates to recommendations put forth by the American Urological Association’s (AUA) Best Practice Statement (BPS) on antimicrobial prophylaxis.Methods: A retrospective chart review of 488 patients undergoing TURP was conducted. Electronic medical records were reviewed to determine antibiotics prescribed 3 hours preoperatively and 24 hours postoperatively. For patients without a catheter, compliance was defined as those receiving an antibiotic prior to TURP. In patients with an indwelling catheter, compliance was defined as those receiving antibiotics from two different classes prior to surgery.Results: Overall, a total of 30 antibiotic regimens were utilized.The most common single antibiotic regimens prescribed were ciprofloxacin (32%), cefazolin (25%) and gentamicin (3%). In those patients with indwelling Foley catheters prior to TURP, a significant increase in gentamicin, as well as combination antibiotic regimens, was noted. The compliance rate with the AUA BPS in patients without a preoperative catheter was 81%, while the compliance rate for patients with an indwelling catheter prior to TURP was 37%.Interpretation: Collectively, our results demonstrate that prescribing patterns vary significantly prior to TURP, with compliance to AUA BPS being lower than anticipated. Overall, these results support educational efforts in this area, and the development of Canadian
The halo split skin graft in the management of non-melanoma skin cancer of the leg: a retrospective study
Authors: Fietz Danika , Sivyer Graham , O'Brien Denis , Rosendahl Cliff 
Published: November 2013

Background: The purpose of this study was to compare the results of the halo split skin graft (HSSG) by two primary care skin cancer practitioners at one clinic at the Gold Coast, Queensland, Australia, to the results of the only previous study while adding to the body of evidence regarding use of the HSSG following excision of non-melanoma skin cancer on the leg.
Method: A retrospective review of the notes (Jan 2010-Aug 2012) was performed of all cases of non-melanoma skin cancer (NMSC) excisions in which split skin graft (SSG) closure with the HSSG was utilized on the leg.
Results: There were a total of 68 HSSGs included over the 31 months of the study. Average lesion size was 19.4 mm (range 9-75 mm) and the average age of patients was 78 years (range 49-95 years) with 49% of patients being male. The average healing time was 4 weeks with 35/68 (51%) healing within 14 to 21 days. The overall infection rate was 8/68 (11.8%), which decreased to 4/53 (7.5%) when the ankle grafts were excluded. The graft failure rate was 7/68 (10%) with 3/68 (4.4%) having both infection and graft failure.
Limitations: This was a retrospective study.
Conclusion: The HSSG confines the surgical wounds to a single site, does not require specialized equipment and it is an economical and effective option for managing NMSC on the leg in situations where skin graft is indicated.
Measurement of Arginine Metabolites: Regulators of Nitric Oxide Metabolism
Authors: Augustine Molly S. , Rogers Lynette K. 
Published: November 2013

AbstractArginine is the substrate for nitric oxide synthases (NOS), and arginine availability regulates the production of nitric oxide. Through the activity of methyltransferases, arginine can be methylated to form monomethylarginine (NMMA), asymmetrical dimethylarginine (ADMA), and symmetrical dimethylarginine (SDMA). NMMA and ADMA directly inhibit NOS, whereas SDMA inhibits the cellular import of arginine through the cationic amino acid transporter. Increased levels of methylarginine compounds have been associated with many diseases including atherosclerosis, renal failure, pulmonary hypertension, and preeclampsia. Previous HPLC methods to measure these molecules rely on derivatization with ortho‐phthalaldehyde, which is unstable and requires immediate pre‐ or post‐column reactions. We have identified a new fluorometric agent that is stable for at least 1 week and provides chromatographic properties that facilitate separation of these chemically similar compounds by reverse phase chromatography.

Published: November 2013

AbstractCongenital diaphragmatic hernia (CDH) has an incidence of around 1/3,000 births. The pathogenesis of this developmental anomaly remains largely unknown and the description of small chromosomal imbalances in cases of CDH is of major interest for the identification of candidate genes. We report on a tandem 4q31.23 triplication encompassing the EDNRA gene identified by array‐CGH in a male presenting an isolated left postero‐lateral CDH. This copy number variation was inherited from the asymptomatic father, carrier of a size‐identical duplication. We demonstrate that EDNRA mRNA is over‐expressed in the proband in blood tissue. Consistent with the expression of EDNRA in the developing diaphragm and the observation that the endothelin system is up‐regulated in human and animal models of CDH, we conclude that the EDNRA triplication may be the cause of CDH in our patient. © 2013 Wiley Periodicals, Inc.
Development of antifouling polyamide thin‐film composite membranes modified with amino‐cyclodextrins and diethylamino‐cyclodextrins for water treatment

ABSTRACTThe fouling behavior of polyamide thin‐film composite (TFC) membranes modified with amino‐ and diethylamino‐cyclodextrins (CDs) through an in situ interfacial polymerization process is reported. Modified polyamide TFC membranes exhibited improved hydrophilicity, water permeability, and fouling resistance as compared to the unmodified TFC membranes, while restricting the passage of NaCl salt (98.46 ± 0.5%). The increase in hydrophilicity was attributed to the secondary and tertiary hydroxyl groups of the CDs, which were not aminated. The membranes modified with amino‐CDs had increased surface roughness while the membranes modified with diethylamino‐CDs had smoother surfaces. However, despite the surface roughness of the membranes modified with amino‐CDs, low fouling was observed due to the highly hydrophilic surfaces, which superseded the roughness. © 2013 Wiley Periodicals, Inc.

Polyethersulfone/polyetherethersulfone copolymers with the same chemical composition and different melt‐viscosity
Authors: Zhou Xiaoming , Liu Baijun , Jiang Zhenhua , Yue Xigui 
Published: November 2013

AbstractRandom, block, and alternative polyethersulfone/polyetherethersulfone copolymers (phenyl: ether: sulfone =7 : 4 : 3) with similar molecular weights and polydispersity were synthesized using different synthetic strategies. DSC and DMA analyses indicated that all copolymers are amorphous and possess extremely close glass transition temperature. The random copolymer displayed higher modulus and complex viscosity. It is interesting to find that the alternative copolymer exhibited a melt viscosity of 281 Pa s, which is much lower than that of the block copolymer (646 Pa s) and the random copolymer (1641 Pa s) at 4 s−1. Moreover, the alternative copolymer showed obviously higher elongation at break of 101.9%. These behaviors were highly related to their different sequence distribution. © 2013 Wiley Periodicals, Inc.

Published: November 2013

AbstractThe green synthesis of silver nanoparticles (AgNPs) in centrifuged natural rubber latex (NRL) by in situ reduction of silver nitrate by NRL is described. The synthesis of AgNP within NRL was successfully carried out without the addition of any reducing agent or stabilizers. The modified AgNP incorporated with centrifuged NRL (GAgNP_NRL) was used to make NRL foam (NRLF) by the Dunlop production method. An ultraviolet–visible (UV‐Vis) spectrophotometer analysis, Zeta potential analysis data and transmission electron micrograph analysis proved that the modified centrifuged NRL consisted of stable nanometer‐sized silver particles. A scanning electron microscopic (SEM)/energy‐dispersive X‐ray spectroscopy (EDX) analysis and UV‐Vis analysis of a latex film made out of the modified GAgNP_NRL compound showed nano‐sized silver particles inside the rubber matrix. The final product of the NRLF (GAgNP_NRLF) made out of the GAgNP_NRL compound was tested for antimicrobial properties against gram‐negative Escherichia coli, gram‐positive Staphylococcus aureus and Staphylococcus epidermidis. The resultant GAgNP_NRLF strongly inhibited the bacteria. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40155.
