Les visions de Daniel et les visées millénaristes dans l’Angleterre de la Révolution puritaine
Authors: Ifrah Lionel
Published: January 2014

Bible et Révolution puritaine sont étroitement liées, la réflexion théologique cherchant son inspiration dans les Écritures et façonnant les comportements politiques. Le livre de Daniel exerce une fascination particulière sur les esprits protestants qui s’identifient aux Saints appelés à triompher dans le royaume de Dieu, promesse que reprendra l’Apocalypse de Jean en décrivant le Millénium. Le prophète hébraïque offre une vaste fresque eschatologique, depuis le songe énigmatique de Nabuchodonosor jusqu’à la vision des quatre bêtes monstrueuses et l’annonce finale des temps messianiques à une date mystérieuse. Source d’une profonde espérance, ce texte a donné lieu à d’innombrables interprétations dont les auteurs, en quête de clefs propres à déchiffrer les événements de leur époque, fournirent une lecture littérale, autrement dit historique et politique. C’est le cas des Millénaristes qui s’en servirent pour bâtir divers systèmes apocalyptiques, dont le plus marquant reste celui qui anima le mouvement de la Cinquième monarchie.
Sources bibliques dans l’oeuvre vocale religieuse de Henry Purcell
Authors: Simon Laurent
Published: January 2014

The development of Henry Purcell’s sacred music in the second half of the seventeenth century originates in a fruitful compromise between the political and religious constraints of Restoration England and the contribution of the continental baroque. The stylistic evolution of his religious compositions reflects the political and religious developments which took place during the successive reigns of Charles II, James II and William of Orange. As a baroque musician and a native of an anti-papist country, Purcell showed considerable skill in the art of setting words to music and managed to blend in the reformers’emphasis on the intelligibility of the text with Counter-Reformation aesthetics.
Les origines juives à la lumière de l’histoire profane : Origines Judaicae de John Toland (1709)
Authors: Lurbe Pierre
Published: January 2014

Origines Judaicae propose une réinterprétation de l’épisode fondateur de la sortie d’Égypte à la lumière du récit qu’en donne le géographe grec Strabon, et non plus en suivant le livre de l’Exode. Prenant le contrepied des thèses de Pierre-Daniel Huet (Demonstratio Evangelica, 1679), Toland voit en Moïse un fondateur d’État, dont la religion aurait été une forme de panthéisme. La prétention de l’Irlandais à

faire véritablement oeuvre d’historien ne peut toutefois être prise au sérieux. Le statut de source fiable accordé à la Géographie de Strabon relève d’un parti pris méthodologique que rien ne justifie, et Toland n’est pas moins infidèle que Huet à la méthode critique : l’un comme l’autre confèrent une autorité injustifiée à certaines sources au détriment d’autres.
Thomas Paine en guerre contre les « faiseurs de Bibles »
Authors: Caron Nathalie
Published: January 2014

Dans Le Siècle de la raison (1794-1795), selon une tradition déjà bien installée dans l’espace transatlantique, le libre penseur Thomas Paine se livra à une attaque sans merci du texte biblique. Le propos était multiple : après s’en être pris à la monarchie héréditaire et à l’alliance de l’Église et de l’État dans les Droits de l’homme (1791-92), Paine chercha dans cet écrit déiste à saper la légitimité des autorités chrétiennes. Il argumentait dans le même temps en faveur du déisme, conçu comme étant la seule religion qui proposait une idée juste de Dieu. Paine entendait contribuer au parachèvement de l’entreprise révolutionnaire entamée en 1776 en incitant ses lecteurs à penser par eux-mêmes, mais aussi en encourageant le débat public.
William Collins’s Odes : description and the "Silent Eye”
Authors: Jung Sandro
Published: January 2014

This article introduces the idea of the silent eye and relates it to the poetry of William Collins (1721-1759). The traditional contextualisation of mid-eighteenth-century poetry as descriptive is reconsidered in order to define the allusive anti-pictorialism and its creation of mood - a sensation to be apprehended in more complex ways than visual perception - that characterise the poet’s spiritual landscapes as much as the deities that he invokes through the hymnal context of his odes. Mood is interpreted as the situational spirituality that the speaker experiences while anticipating the encounter with

the deity. Collins’s desire to be non-visual in his depiction of the speaker’s

apprehension of the divine is explained with the limitations of pictorial representations in which sublime obscurity is destroyed in favour of definite

images. A mimetic representation of the divine and the speaker’s experience ofit

according to Collins must not be pictorial as it then loses its mystery and charm.
German Immigrants and the Birth of the Piano in Great Britain: Bach, Zumpe, their friends and the square piano
Authors: Portier François
Published: January 2014

In the late 1760s small "square pianos" began to appear in

significant numbers in Great Britain. They soon enjoyed an enormous success and were produced in great quantities. They were widely exported all over Europe. The role of German immigrants, notably Johannes Zumpe and Johann Christian Bach, is especially significant in the early technical and artistic history of the new instrument. Square pianos were comparatively cheap, which made them accessible to music-loving amateurs from the middle as well as the upper class. The aim of this paper is to seek the aesthetic as well as social causes of this spectacular success, while focusing on the role of the small community of German musicians and craftsmen living in London.
Assessment of immunoglobulin G antibodies against oxidized low-density lipoproteins in patients with acute coronary syndrome
Authors: Mokhtar Mohamed S. , Hassan Zaghla Hanan E. , Samy Wael , Mahmoud Abdou
Published: January 2014

Background

Oxidative modification of low-density lipoproteins (LDLs) induces formation of immunogenic epitopes in the LDL molecule, which leads to the formation of antibodies against oxidized low-density lipoprotein (OxLDL) that can be detected in serum.

Aim of the study

The objective of this study was to evaluate the association between autoantibodies against OxLDL and acute coronary syndrome (ACS).

Patients and methods

A total of 50 patients diagnosed as having ACS (37 male patients and 13 female patients), age ranging between 19 and 82 years and admitted to the critical care department, Cairo University, and 19 matched healthy controls were enrolled in our study. All patients were subjected to detailed medical history-taking and physical examination, serial 12-lead ECGs, serial cardiac biomarkers on admission and 24 h later, echocardiography, coronary angiography and assessement of severity using the Gensini score, and IgG anti-OxLDL antibodies measurement.

Results

We found significant difference in the level of antibody between patients with ACS and matched healthy controls (P < 0.001). With respect to the correlation of anti-OxLDL antibodies and the severity of ACS, we found significant correlation between the level of antibodies in patients with ACS as assessed by the Gensini score (r = 0.709) as well as between the echocardiographic findings as assessed by the wall motion score index (r = 0.589). During hospitalization, there was significant correlation of the antibody level with mechanical complications (P = 0.047) and needed immediate intervention (P < 0.001). However, the antibody level was correlated with malignant arrhythmias but P value (0.219) was insignificant because of high SD, and there was no correlation with ischemic complications (P = 0.798).

Conclusion

With respect to the correlation of anti-OxLDL antibodies and ACS, the patients with ACS had higher anti-OxLDL antibodies level. In addition, anti-OxLDL antibodies level was correlated with the Gensini score, wall motion score index, and major adverse cardiovascular events during hospitalization.
Serum visfatin in chronic renal failure patients on maintenance hemodialysis: a correlation study
Authors: Lotfy Abdel Wahab M. , Mohammed Nagwa A. , El-Tokhy Hanan M. , Attia Fatma A.
Published: January 2014

Background and aim of work

Endothelial dysfunction, atherosclerosis, and cardiovascular disease are strongly linked to chronic kidney disease. It has been hypothesized that visfatin may play an important role in uremia-related atherosclerosis and the relation between visfatin and endothelial dysfunction has been proved. We aimed to study and characterize the relation of visfatin to some clinical and biochemical parameters among chronic renal failure (CRF) patients on regular hemodialysis.

Patients and methods

This study was carried out on a total of 90 individuals, divided into two groups: group A included 68 patients with CRF on regular hemodialysis (44 men and 24 women) and group B included 22 healthy individuals as controls (four men and 18 women). All participants were subjected to the following: full clinical assessment, BMI assessment, FBS (Fasting blood sugar), PPBS (postprandial blood sugar), Hb level, lipid profile, serum urea, creatinine, potassium, phosphorus, and serum visfatin.

Results

Serum visfatin concentration was significantly high in group A (uremic on hemodialysis) compared with group B (control) (48.95 ng/ml ±11.62 compared with 22.65 ng/ml ± 5.24; P < 0.001); a highly significant positive correlation was found between serum visfatin and serum low-density lipoprotein (r = 0.39; P < 0.001) and a significant positive correlation between serum visfatin and serum triglycerides and serum uric acid (r = 0.28; P < 0.05 and r = −0.24; P < 0.05), respectively, whereas a highly significant negative correlation between serum visfatin and Hb (r = −0.43; P < 0.001) and a significant negative correlation between serum visfatin and serum urea (r = −0.25; P < 0.05), blood sugar, both fasting and postprandial (r = −0.34; P < 0.001 and r = −0.39; P < 0.001), respectively, were found in the patients in group A, without a significant correlation either to high-density lipoprotein, serum creatinine, the etiology of CRF, or to the duration of dialysis in the patients in group A.

Conclusion

This study proves the association of serum visfatin with CRF, unrelated to the biochemical parameter of kidney functions; however, further studies to examine visfatin expression within renal tissue may clarify its definitive role in CRF.
Association between insulin resistance, metabolic syndrome, and duration of hepatitis C in Egyptian patients
Authors: Zakaria Ebtissam , Fayad Tarek , Rizk Mary N. , Ghanem Nashwa S. , Kamal Maisa
Published: January 2014

Background

Chronic hepatitis C virus (HCV) infection affects around 170 million individuals worldwide. Egypt has one of the highest prevalence of patients with HCV worldwide. A higher prevalence of insulin resistance (IR) is found in this population.

Aim

The aim of this work was to study the relation between IR, metabolic syndrome (MS), and hepatitis C in nondiabetic patients and to assess their relation to the duration of HCV infection.

Patients and methods

This was a cross-sectional study of 50 participants matched for age (49 ± 7.6 years), sex, and BMI. These participants were divided into three groups: 20 controls, 15 patients with HCV for less than 10 years’ duration, and 15 patients with HCV for more than 10 years. We assessed patients for MS according to the AACE diagnostic criteria. Fasting and postprandial insulin levels were also assessed. IR was evaluated using the homeostasis model assessment-insulin resistance (HOMA-IR) equation.

Results

There was a statistically significant difference in HOMA-IR levels between controls (median 0.43 μU/ml) and those with HCV for more than 10 years (median 0.75 μU/ml; P = 0.001) as well as those with HCV for less than 10 years (median 0.89 μU/ml; P = 0.001). There was no significant difference in HOMA-IR levels between both groups of HCV (P = 0.8). The increase in the HOMA-IR test values was mainly because of increased fasting insulin levels in both groups because of the significant positive correlation between HOMA-IR and fasting insulin in patients with chronic HCV less than and those more 10 years’ duration (r = 0.902, r = 1, respectively; P = 0.001 in both groups). MS was found in four of 15 patients in each group of patients; yet, none of the controls fulfilled the diagnosis criteria.

Conclusion

MS and IR are significantly higher in Egyptian HCV patients when compared with normal controls irrespective of the duration of HCV.
Angiopoietin-2 in chronic renal failure patients on hemodialysis: relationship with glomerular filtration rate in the predialysis stages
Authors: Attia Fatma A. , Mohammed Nagwa A. , Ibrahim Al-Shymaa A.
Published: January 2014

Introduction

Cardiovascular disease has increased as a complication of chronic kidney disease even in the absence of diabetes or hypertension. Angiopoietin-1 and 2 are 55 kDa antagonistic nonredundant gatekeepers of endothelial activation and thus are potential important factors in accelerated atherosclerosis.

Aim of the study

The aim of the study was to determine angiopoietin-2 level in patients on hemodialysis (stage 5) and in the predialytic stages (stages 3 and 4) and to find the relationship between angiopoietin-2 levels and glomerular filtration rate in the predialytic stages.

Patient and methods

We prospectively studied 75 patients divided into three groups and 12 healthy controls. Group 1 included 33 patients on maintenance hemodialysis three times a week; group 2 included 21 patients with stage 3 chronic kidney disease; and group 3 included 21 patients with stage 4 chronic kidney disease.

Results

We found highly significant (P < 0.01) increase in mean serum angiopoietin-2 levels in all three groups compared with the control. The mean angiopoietin-2 in group 1 was 1669.09 ± 472.64 pg/ml, in group 2 was 1206.91 ± 154.26 pg/ml, in group 3 was 1642.24 ± 113.01 pg/ml, and in control was 476.29 ± 150.37 pg/ml. Furthermore, we found highly significant (P < 0.01) increase in group 1 compared with group 2 and group 3, and in group 3 compared with group 2. Our result revealed significant negative correlation of angiopoietin-2 level with estimated glomerular filtration rate in group 2 (r – 0.858, P < 0.01) and group 3 (r – 0.825, P < 0.01), with hemoglobin in group 1 (r – 0.438, P < 0.01), and with BMI (r − 0.468, P < 0.05) and cholesterol (r − 0.503, P<0.05) in group 3; significant positive correlation was observed with uric acid (r 0.456, P < 0.05) in group 3.

Conclusion

Circulating angiopoietin-2 is a putative marker and potential mediator of atherosclerosis, is inversely related to glomerular filtration rate, and is increased with advanced chronic kidney disease. Normolipidemia in chronic kidney disease patients does not prevent atherosclerotic burden; this is because of the presence of other markers such as angiopoietin-2.
Why Agricultural Educators Remain in the Classroom
Authors: Crutchfield Nina , Ritz Rudy , Burris Scott
Published: January 2014

The purpose of this study was to identify and describe factors that are related to agricultural educator career retention and to explore the relationships between work engagement, work-life balance, occupational commitment, and personal and career factors as related to the decision to remain in the teaching profession. The target population for this study was defined as experienced agricultural educators who had completed a minimum of four years of teaching experience, who were currently employed in a secondary agricultural education classroom for the 2009-2010 school calendar. The accessible population consisted of those experienced agricultural educators in the southern region of the United States: Alabama, Arkansas, Florida, Georgia, Louisiana, Mississippi, North Carolina, South Carolina, and Tennessee. The study sought responses from stratified random sample of those teachers to ensure geographical and gender representation equivalent that of the target population. This study employed descriptive-correlational research procedures. The instrument was constructed utilizing portions of four studies to measure the variables of interest. A linear regression analysis revealed a 25% variance in occupational commitment attributed to work-life balance and work engagement combined.
An Exploration of the Motivational Profile of Secondary Urban Agriculture Students
Authors: Anderson II James C.
Published: January 2014

This descriptive-correlational study examined the personal factors that may affect the self-determination
of 110 freshmen who have elected to enroll in an urban agriculture program. The personal factors,
termed the motivational profile, consisted of influences in the decision to enroll in the program, the
student’s type of motivation to attend the agriculture program, satisfaction with that decision, and
perceived effort during academic tasks related to agriculture. Results show that when students perceive
they have an influence in the decision to enroll in the program, they are more satisfied with the decision
and more likely to report exerting a moderate to high effort on academic tasks related to agriculture.
This study has implications for establishing a body of knowledge on non-rural student motivation toward
agriculture that can impact teacher training, educational interventions targeting student achievement,
and student recruitment and retention into agriculture.
On transition-zone water clouds
Authors: Hirsch E. , Koren I. , Levin Z. , Altaratz O. , Agassi E.
Published: January 2014

Abstract. A recent field campaign was conducted to measure the properties of thin, warm, convective clouds forming under conditions of weak updrafts. During the campaign, short-lived clouds (on the order of minutes) with droplets' effective radius of 1–2 μm and low liquid water path (~500 mg m−2) were measured. These low values are puzzling, since in most studies an effective radius of 4 μm is reported to serve as the lower bound for clouds. A theoretical cloud model designed to resolve the droplet-activation process suggested conditions that favor the formation of such clouds. Here we show that these clouds, which mark the transition from haze to cloud, are highly sensitive to the magnitude of the initial perturbation that initiated them. We define these clouds as "transition-zone clouds". The existence of such clouds poses a key challenge for the analysis of atmospheric observations and models, since they "further smooth" the transition from dry aerosol through haze pockets to cumulus clouds.
Combining airborne gas and aerosol measurements with HYSPLIT: a visualization tool for simultaneous evaluation of air mass history and back trajectory consistency
Authors: Freitag S. , Clarke A. D. , Howell S. G. , Kapustin V. N. , Campos T. , Brekhovskikh V. L. , Zhou J.
Published: January 2014

Abstract. The history of air masses is often investigated using backward trajectories to gain knowledge about processes along the air parcel path as well as possible source regions. Here, we describe a refined approach that incorporates airborne gas, aerosol, and environmental data into back trajectories and show how this technique allows for simultaneous evaluation of air mass history and back trajectory reliability without the need to calculate trajectory errors. We use the HYbrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model and add a simple semi-automated computing routine to facilitate high-frequency coverage of back trajectories initiated along free tropospheric (FT) flight tracks and profiles every 10 s. We integrate our in situ physiochemical data by color-coding each of these trajectories with its corresponding in situ tracer values measured at the back trajectory start points along the flight path. The unique color for each trajectory aids assessment of trajectory reliability through the visual clustering of air mass pathways of similar coloration. Moreover, marked changes in trajectories associated with marked changes evident in measured physiochemical or thermodynamic properties of an air mass add credence to trajectories. This is particularly true when these air mass properties are linked to trajectory features characteristic of recognized sources or processes. This visual clustering of air mass pathways is of particular value for large-scale 3-D flight tracks common to aircraft experiments where air mass features of interest are often spatially distributed and temporally separated. The cluster-visualization tool used here reveals that most FT back trajectories with pollution signatures measured in the central equatorial Pacific reach back to sources on the South American continent over 10 000 km away and 12 days back in time, e.g., the Amazonian basin. We also demonstrate the distinctions in air mass properties between these and trajectories that penetrate deep convection in the Inter-Tropical Convergence Zone. Additionally, for the first time we show consistency of modeled precipitation along back trajectories with scavenging signatures in the aerosol measured for these trajectories.
Towards modelling flood protection investment as a coupled human and natural system
Authors: O'Connell P. E. , O'Donnell G.
Published: January 2014

Abstract. Due to a number of recent high-profile flood events and the apparent threat from global warming, governments and their agencies are under pressure to make proactive investments to protect people living in floodplains. However, adopting a proactive approach as a universal strategy is not affordable. It has been argued that delaying expensive and essentially irreversible capital decisions could be a prudent strategy in situations with high future uncertainty. This paper firstly uses Monte Carlo simulation to explore the performance of proactive and reactive investment strategies using a rational cost–benefit approach in a natural system with varying levels of persistence/interannual variability in annual maximum floods. It is found that, as persistence increases, there is a change in investment strategy optimality from proactive to reactive. This could have implications for investment strategies under the increasingly variable climate that is expected with global warming. As part of the emerging holistic approaches to flood risk management, there is increasing emphasis on stakeholder participation in determining where and when flood protection investments are made, and so flood risk management is becoming more people-centred. As a consequence, multiple actors are involved in the decision-making process, and the social sciences are assuming an increasingly important role in flood risk management. There is a need for modelling approaches which can couple the natural and human system elements. It is proposed that coupled human and natural system (CHANS) modelling could play an important role in understanding the motivations, actions and influence of citizens and institutions and how these impact on the effective delivery of flood protection investment. A framework for using agent-based modelling of human activities leading to flood investments is outlined, and some of the challenges associated with implementation are discussed.
Integrating ASCAT surface soil moisture and GEOV1 leaf area index into the SURFEX modelling platform: a land data assimilation application over France
Authors: Barbu A. L. , Calvet J.-C. , Mahfouf J.-F. , Lafont S.
Published: January 2014

Abstract. The land monitoring service of the European Copernicus programme has developed a set of satellite-based biogeophysical products, including surface soil moisture (SSM) and leaf area index (LAI). This study investigates the impact of joint assimilation of remotely sensed SSM derived from Advanced Scatterometer (ASCAT) backscatter data and the Copernicus Global Land GEOV1 satellite-based LAI product into the the vegetation growth version of the Interactions between Soil Biosphere Atmosphere (ISBA-A-gs) land surface model within the the externalised surface model (SURFEX) modelling platform of Météo-France. The ASCAT data were bias corrected with respect to the model climatology by using a seasonal-based CDF (Cumulative Distribution Function) matching technique. A multivariate multi-scale land data assimilation system (LDAS) based on the extended Kalman Filter (EKF) is used for monitoring the soil moisture, terrestrial vegetation, surface carbon and energy fluxes across the domain of France at a spatial resolution of 8 km. Each model grid box is divided into a number of land covers, each having its own set of prognostic variables. The filter algorithm is designed to provide a distinct analysis for each land cover while using one observation per grid box. The updated values are aggregated by computing a weighted average. In this study, it is demonstrated that the assimilation scheme works effectively within the ISBA-A-gs model over a four-year period (2008–2011). The EKF is able to extract useful information from the data signal at the grid scale and distribute the root-zone soil moisture and LAI increments throughout the mosaic structure of the model. The impact of the assimilation on the vegetation phenology and on the water and carbon fluxes varies from one season to another. The spring drought of 2011 is an interesting case study of the potential of the assimilation to improve drought monitoring. A comparison between simulated and in situ soil moisture gathered at the twelve SMOSMANIA (Soil Moisture Observing System–Meteorological Automatic Network Integrated Application) stations shows improved anomaly correlations for eight stations.
Flood risk assessment: concepts, modelling, applications
Authors: Tsakiris G.
Published: January 2014

Abstract. Natural hazards have caused severe consequences to the natural, modified and human systems, in the past. These consequences seem to increase with time due to both higher intensity of the natural phenomena and higher value of elements at risk. Among the water related hazards flood hazards have the most destructive impacts. The paper presents a new systemic paradigm for the assessment of flood hazard and flood risk in the riverine flood prone areas. Special emphasis is given to the urban areas with mild terrain and complicated topography, in which 2-D fully dynamic flood modelling is proposed. Further the EU flood directive is critically reviewed and examples of its implementation are presented. Some critical points in the flood directive implementation are also highlighted.

Abstract. Fabric (distribution of crystallographic orientations) profile along the full NEEM ice core, Greenland, is presented in this work. Data were measured in the field by an Automatic Ice Texture Analyzer every 10 m, from 33 m down to 2461 m depth. The fabric evolves from a slightly anisotropic fabric at the top, toward a strong single maximum at about 2300 m, which is typical of a deformation pattern mostly driven by uniaxial compression and simple shearing. A sharp increase in the fabric strengthening is observed at the Holocene to Wisconsin climatic transition. A similar strengthening, toward an anisotropic single maximum-type fabric, has been observed in several ice cores from Greenland and Antarctica, and can be attributed to a positive feedback between changes in ice viscosity at the climatic transition, and the impact of a shear component of stress. Centimeter scale abrupt texture (fabric and microstructure) variations are observed in the bottom part of the core. Their positions are in good agreement with the folding hypothesis used for a climatic reconstruction by Dahl-Jensen et al. (2013). Comparison is made to two others ice cores drilled along the same ridge; the GRIP ice core drilled at the summit of the ice sheet, and the NorthGRIP ice core, drilled 325 km to the NNW of the summit along the ridge, and 365 km upstream from NEEM. The fabric profile clearly reflects the increase in shear deformation when moving NW along the ridge from GRIP to NorthGRIP and NEEM. The difference in fabric profiles between NEEM and NorthGRIP also evidences a stronger lateral extension associated with a sharper ridge at NorthGRIP.
Vesicouterine fistula presenting with urinary incontinence 30 years after primary Cesarean: Case report and review of the literature
Authors: Gungor Ugurlucan Funda , Bastu Ercan , Bakir Baris , Yalcin Onay
Published: January 2014

A vesicouterine fistula is an abnormal communication between the bladder and the uterus. The most common cause is lower segment Cesarean section. Conservative treatment may be applied in some cases, but surgery is the definitive treatment. We present a 55-year-old woman with vesicouterine fistula after primary Cesarean section; she presented with urinary incontinence 30 years later. Methylene blue dye test was performed and drainage of urine dyed with methylene blue through the uterine cervix was observed. Diagnosis was confirmed with magnetic resonance imaging. Total abdominal hysterectomy and bilateral oophorectomy was performed and the bladder wall was sutured in a double layer with 2/0 polyglycolic suture. No complications developed and the patient did not suffer from any urinary incontinence afterwards. Vesicouterine fistula should be suspected in cases presenting with urinary incontinence even years after Cesarean section; diagnostic tests and, if necessary, appropriate surgery should be performed.

Published: January 2014

Concomitant urethral injury is rare in penile fracture. We report the case of a 34-year-old male who presented to the emergency department 12 hours after a blunt self-injury of the penis. Physical examination revealed a swollen, ecchymotic, and deviated circumcised penis without blood at the meatus. The fracture line extending along the bilateral corpora without urethral involvement was seen intraoperatively. The fracture side was repaired primarily. The patient healed and recovered without complication. To our knowledge, this is the second reported case of bilateral corporeal rupture without urethral involvement.

Published: January 2014

Introduction: We evaluate the efficiency of alpha-adrenergic antagonists on stone clearance after extracorporeal shock wave lithotripsy (ESWL) in patients with lower ureteral stones.Methods: A total of 356 patients with solitary lower ureteral stones who underwent single ESWL sessions were divided into 2 groups. Group 1 received our standard medical therapy, and Group 2 was treated with 0.4 mg/day tamsulosin for a maximum of 2 weeks. All patients were re-evaluated with plain film radiography and ultrasound each week during the treatment period. A computed tomography scan was systematically performed 3 months after ESWL.Results: In total, 82 of the 170 patients in Group 1 (48.2%) and 144 of the 186 patients in Group 2 (77.4%) (p = 0.002) were stone free. Among the patients with stones 10 to 15 mm in diameter, the stone-free rate was 38.4% in Group 1 and 77.1% in Group 2 (p = 0.003). Average stone expulsion time was 10.6 days and 8.4 days in Groups 1 and 2, respectively. Ureteral colic occurred in 40 patients (23.5%) in Group 1, but only in 10 patients (5.3%) in Group 2 (p = 0.043). The only side effect of tamsulosin was slight dizziness in 5 of the 186 patients in Group 2 (2.6%).Conclusion: Adjunctive therapy with alpha1-adrenergic antagonists after ESWL is more efficient than, and equally as safe as, lithotripsy alone to manage patients with lower ureteral stones. The adding of alpha-blockers is more reliable and helpful for stones with a large dimension, and can also decrease stone elimination time and episodes of ureteral colic.

Published: January 2014

Introduction: We evaluate the efficacy of the Peristeen (Coloplast A/S, Kokkedal, Denmark) transanal irrigation (TAI) system, as a stool cleansing mechanism, to gain stool continence in children who need reconstructive bladder surgery and have fecal incontinence.Methods: We prospectively evaluated children with neuropathic bladder and bowel dysfunction who were intended for reconstructive bladder surgery and the Malone antegrade continence enema (MACE) procedure. All patients were started on the Peristeen TAI system at least 3 months before surgery to assess their response. Each patient’s bowel function, frequency of using the system, satisfaction (and that of their parents) and diaper independency were evaluated before and after reconstructive surgery.Results: We included 18 patients (11 female, 7 male) who were evaluated from April 2006 to the present. The mean age of the group was 7.6 years (range: 4-15). Fifteen patients (83.3%) showed complete dryness from stools. Of the 15 patients, 8 (53.3%) were able to be diaper-free, while 6 continued wearing diapers due to fear of soiling and 1 due to urinary incontinence. The patients underwent reconstructive bladder surgery and continued to use the Peristeen TAI system with the same results postoperatively. The main limitation of this study is the small number of patients included, although this is a very specific patient group.Conclusion: Our initial results suggest that the Peristeen TAI system is a successful conservative substitute for the MACE procedure in children who require reconstructive bladder surgery.

Published: January 2014

We present the case of a 34-year-old female, complaining of frequent micturition and progressive dysuria. By cystoscopy and computerized tomography, we found that she had multiple submucosal protuberant lesions in the entire bladder. After surgical excision, she has thus far showed no further signs of the disease. The postoperative histopathologic examination revealed a ganglioneuroma and leiomyomatosis. Urinary bladder paraganglioma is an unusual tumour; when it is combined with leiomyomatosis, it is extremely rare. We describe the main clinical presentation, diagnostic procedures, and pathologic features. We also review the English literature.

Introduction: We evaluate patient-reported satisfaction and cosmesis of laparoendoscopic single-site adrenalectomy (LESS-A) in comparison with that of conventional laparoscopic adrenalectomy (CLA).Methods: A total of 19 and 104 patients who respectively underwent LESS-A and CLA between May 1996 and June 2011 were included in the study. Questionnaires inquiring about scar pain (0: not painful, 10: very painful), satisfaction (0: not satisfied, 10:very satisfied) and cosmesis (0: very unsightly, 10: very beautiful) on the basis of a visual analogue scale were sent to patients postoperatively.Results: The respondents consisted of 11 and 54 patients who underwent LESS-A and CLA, respectively. There was no significant inter-group difference in age, sex, affected side or body mass index. No significant differences were observed in operative time or estimated blood loss. There were also no significant differences in pain (0.67 vs. 0.57, p = 0.393), satisfaction (8.92 vs. 8.46, p = 0.453), or cosmesis score (8.58 vs. 8.00, p = 0.487) between the LESS-A and CLA groups overall. In female patients, the satisfaction score was significantly higher in the LESS-A group than in the CLA group (10.0 vs. 8.72, p = 0.049). In young patients (<50 years old), the satisfaction score was also significantly higher in the LESS-A group than in the CLA group (9.17 vs. 6.38, p = 0.036).Conclusions: Young patients and female patients who had received LESS-A adrenal surgery were more satisfied with the scar outcomes than were the young patients and female patients who had received CLA. We suggest that this patient subset most values the cosmetic benefits of LESS-A.
L’apport du fonctionnement en communauté d’apprentissage professionnelle de huit écoles inclusives sur l’autoappréciation en enseignement en littératie et sur le sentiment d’autoefficacité

Published: January 2014

Cet article présente les résultats d’une recherche sur le fonctionnement d’écoles en communauté d’apprentissage professionnelle (CAP) et sur sa contribution au développement professionnel des enseignants. Bien que plusieurs auteurs s’intéressent au fonctionnement des écoles en CAP, peu de recherches ont essayé de comprendre son apport à l’autoappréciation des connaissances et des compétences en enseignement en littératie et au sentiment d’autoefficacité en enseignement. Les données recueillies portent sur une période de trois ans suivant un protocole en deux temps (pré et post) auprès de 89 enseignants. Les connaissances et les compétences en enseignement en littératie ainsi que le sentiment d’autoefficacité ont été évalués au moyen de deux questionnaires réalisés au début de l’expérimentation et après trois ans. Une augmentation statistiquement significative des compétences et des connaissances en enseignement ainsi que celle de l’autoefficacité en enseignement ont été observées entre le début et la fin de la recherche. Les résultats suggèrent que le fonctionnement en CAP associé aux activités de formation et d’accompagnement aurait une influence sur les connaissances et les compétences en enseignement en littératie et, qui plus est, sur le sentiment d’autoefficacité en enseignement.

Published: January 2014

Cet article présente les résultats d’une recherche visant à mieux comprendre l’apport des communautés d’apprentissage professionnelles (CAP) à l’égard des élèves doués. Les auteurs s’interrogent sur la capacité d’une CAP à identifier les élèves doués, à dépister leurs besoins et à mettre en place les mesures pour y répondre. La recherche, de type exploratoire et qualitatif, a permis de recueillir les représentations de six enseignants d’un district scolaire francophone du Nouveau-Brunswick, soit deux pour chacun des trois ordres d’enseignement. Leurs représentations ont été validées auprès d’un groupe composé d’enseignants ressources. Des entrevues semi-dirigées, une entrevue de groupe et une analyse documentaire ont servi de méthodes et de techniques de recherche. La collecte de données s’est déroulée durant l’année scolaire 2011-2012. Les résultats montrent que les CAP implantées au Nouveau-Brunswick constituent une approche efficiente et efficace pour identifier les élèves à risque, dépister leurs besoins et y répondre. Bien que ces CAP n’aient pas pour mission de prioriser le phénomène de la douance, les stratégies élaborées en CAP ont des retombées positives sur tous les élèves, y compris les élèves doués. La démarche en CAP pourrait néanmoins être revue afin de mieux répondre aux besoins de ces derniers.

Cette recherche porte sur l’implantation d’une communauté d’apprentissage professionnelle chez des enseignants en adaptation scolaire au secondaire, lesquels partagent la volonté de rehausser la réussite de leurs élèves en lecture. L’étude vise à comprendre de quelle façon la direction d’une école favorise l’implantation de ce mode de fonctionnement. Les données issues des entrevues semi-dirigées individuelles et de groupe montrent que la direction d’école joue un rôle clé dans ce processus et que certaines actions sont cruciales, notamment celles qui consistent à mobiliser le personnel autour d’une vision commune, à fournir les conditions nécessaires et à instaurer une pratique réflexive où les données issues des apprentissages des élèves occupent une place centrale. Certains défis doivent également être surmontés par les directions d’école, entre autres la surcharge de travail occasionnée par ce mode de fonctionnement. Cette étude saura profiter aux gestionnaires scolaires intéressés par le travail en communauté d’apprentissage professionnelle en vue d’améliorer la réussite éducative.

Au Québec, depuis les années 1960, les différentes réformes ont provoqué des bouleversements dans les pratiques éducatives des enseignants du secondaire. Ces changements posent de nombreux défis aux enseignants, notamment sous l’angle du développement de leurs compétences professionnelles. Dès lors, des mesures de soutien aux enseignants doivent être mises en place afin de les accompagner dans cette transformation de leurs pratiques professionnelles. Dans cet article, nous faisons état d’une recherche-action menée dans une école située dans un milieu socioéconomique faible auprès d’enseignants de différentes disciplines scolaires désireux d’améliorer l’apprentissage chez leurs élèves. Le dispositif descercles d’apprentissage et d’inclusiona permis aux enseignants de se mobiliser autour d’un socle commun de pratiques pédagogiques et de s’inscrire dans une démarche réflexive quant aux conditions nécessaires pour mieux intervenir auprès des élèves en difficulté intégrés en classe ordinaire. L’analyse des résultats montre qu’au terme de la recherche-action les enseignants perçoivent des améliorations du climat de la classe, des apprentissages réalisés par leurs élèves et des liens professionnels qu’ils ont tissés grâce au dispositif. Nous désirons surtout rendre compte de l’articulation indispensable des différentes ressources pour que survienne le changement attendu.
Design and Assessment of a Virtual Platform for Impulse Voltage Tests
Authors: Tao Jinsong , Wen Xishan , Song Jingzhe
Published: January 2014

An innovative method to teach undergraduate courses in high-voltage test technology is presented in this paper. The method splits the impulse voltage test into two parts; one is the traditional physical way for high-voltage measurement, and the other is software simulation on a virtual platform. The virtual platform is designed with macromedia and programmed with C language. Probability theories have been introduced to establish its mathematic model. Then verification is presented of the validity of the simulation.
On Resonance and Frequency Response Characteristics of Electrical Circuits
Authors: Drieberg Micheal , Sahoo Nirod Chandra
Published: January 2014

While teaching network analysis to undergraduate students, the frequency response of electrical circuits consisting of passive elements such as resistors, capacitors and inductors are commonly analysed. Students are familiar with the sharp amplitude peak or trough normally occurring at resonance. This observation is not only intuitively pleasing, but also consistent with the concept of resonance in many physical systems. In the well-known series and parallel RLC circuits, the maximum and minimum currents, respectively, occur at resonance. Because of this, many students and even instructors (sometimes) may erroneously assume that the resonance in general RLC circuits implies maximum or minimum current. In this paper, it will be shown that this is generally untrue. The theoretical analyses and experimental validation of series, parallel and series-parallel RLC circuits are presented to address this common misconception.
Educational Applications of Interactive Tools to Analyze, Design, and Simulate D.C.-D.C. Power Converters
Authors: López-Santos Oswaldo , Rico Andrés Mauricio
Published: January 2014

Currently, interactivity is playing a fundamental role in engineering education because of the development of communications and systems. An important challenge is the effective use of computer tools that allow associating teaching methods with the new ways students learn. In the area of power electronics, recognizing different concepts of switching converters is simplified, given simulation and experimentation tools. Nevertheless, general-purpose tools applied in the analysis and simulation of power electronics systems do not make use of the full interactivity that computer applications can offer. Consequently, it is necessary to develop modern tools with specific capacities to complement teaching and research experiences in power electronics. This article describes the Power Electronics Interactive Laboratory implemented in LabVIEW as a tool to introduce interactivity in power electronics education and presents results of its application in research and teaching activities.
USP13 antagonizes gp78 to maintain functionality of a chaperone in ER-associated degradation

Physiological adaptation to proteotoxic stress in the endoplasmic reticulum (ER) requires retrotranslocation of misfolded proteins into the cytoplasm for ubiquitination and elimination by ER-associated degradation (ERAD). A surprising paradox emerging from recent studies is that ubiquitin ligases (E3s) and deubiquitinases (DUBs), enzymes with opposing activities, can both promote ERAD. Here we demonstrate that the ERAD E3 gp78 can ubiquitinate not only ERAD substrates, but also the machinery protein Ubl4A, a key component of the Bag6 chaperone complex. Remarkably, instead of targeting Ubl4A for degradation, polyubiquitination is associated with irreversible proteolytic processing and inactivation of Bag6. Importantly, we identify USP13 as a gp78-associated DUB that eliminates ubiquitin conjugates from Ubl4A to maintain the functionality of Bag6. Our study reveals an unexpected paradigm in which a DUB prevents undesired ubiquitination to sharpen substrate specificity for an associated ubiquitin ligase partner and to promote ER quality control.

We investigated the photoluminescence (PL) efficiency of GaN(0001) single crystals with clean and well-defined surfaces using the PL technique in ultrahigh vacuum in situ. We found typical degradation factors: native oxides at the top surface, damaged layers in the subsurface, and hydrogenated non-radiative states inside bulk GaN. By eliminating the degradation factors, a band-to-band PL intensity of approximately 120 times higher than that of the as-received samples was achieved. The PL efficiency enhancement mechanism is discussed, and the role of hydrogen in GaN crystals is proposed.
