Authors: Trojanowski Stanisław , Ciszek Marian , Maievskyi Eduard 
Published: May 2014

Abstract
One of the most important parameters, crucial to applications of superconductors in cryo-electrotechnique, is power loss. Measurements of losses in superconducting long sample wires require AC magnetic fields of a special geometry and appropriate high homogeneity. In the paper part of the theoretical basis for calculations and a simple design method for a race-track coil set are presented. An example of such home-made coils, with a magnetic field uniformity of about 0.2 % over the range of about 8 cm, is given. Also a simple electronic measurement system for the determination of AC magnetization loss in samples of superconducting tapes is presented.

Abstract
Considering the low efficiency during the process of traditional calibration for digital-display vibrometers, an automatic calibration system for vibrometers based on machine vision is developed. First, an automatic vibration control system is established on the basis of a personal computer, and the output of a vibration exciter on which a digital-display vibrometer to be calibrated is installed, is automatically adjusted to vibrate at a preset vibration level and a preset frequency. Then the display of the vibrometer is captured by a digital camera and identified by means of image recognition. According to the vibration level of the exciter measured by a laser interferometer and the recognized display of the vibrometer, the properties of the vibrometer are calculated and output by the computer. Image recognition algorithms for the display of the vibrometer with a high recognition rate are presented, and the recognition for vibrating digits and alternating digits is especially analyzed in detail. Experimental results on the built-up system show that the prposed image recognition methods are very effective and the system could liberate operators from boring and intense calibration work for digital-display vibrometers
Doris Lessing's The Grass is Singing: a Projection of Naturalism
Authors: Tiwari Rajendra P 
Published: May 2014

This article explores the demonstration of naturalism in Doris Lessing’s first tragic novel the Grass is Singing. It relates how the main characters in the novel are influenced by their instinct, their social and economic environment and how their failure or success depends on their adaptability and ability to compete in the struggle for survival. It is based on library study and textual analysis. Result shows that the central characters, Mary Turner and Moses, are the victims of heredity (sexual instinct) and environment (social, economic and political forces), and Dick Turner suffers the consequence of his environment and his failure to prove himself in the competition or struggle for survival.

Authors: Eiselt M. , Schlattmann P. , Witte H. , Schiecke K. 
Published: May 2014

SummaryIntroduction: This article is part of the Focus Theme of Methods of Information in Medicine on “Biosignal Interpretation: Advanced Methods for Neural Signals and Images“.Objectives: The aim of this study was to compare rhythmicities in the quadratic phase coupling (QPC) in the tracé discontinue EEG patterns (TD) of premature newborns and the tracé alternant EEG patterns (TA) of full-term newborns by means of time-variant bispectral analysis. Both pattern occur during quiet sleep and are characterized by an ongoing sequence of interburst and burst patterns. The courses of time-variant bispectral measures during the EEG burst most likely indicate specific interrelations between cortical and thalamocortical brain structures.Methods: The EEG of a group of premature (n = 5) and of full-term (n = 5) newborns was analysed. Time-variant QPC was investigated by means of time-variant parametric bispectral analysis. The frequency plain [0.5 Hz, 1.5 Hz] × [3 Hz, 6 Hz] was used as the region-of-interest (ROI).Results: QPC rhythms with a frequency of 0.1 Hz (8 – 11 s) were found in all full-term newborns at all electrodes. For the premature newborns the QPC rhythms were less stable and slower (< 0.1 Hz, 11 – 17 s) at all electrodes and showed a higher inter-individual variation than for the full-term newborns. Statistically, the adaptation of a linear mixed model revealed a difference of about 5 s between both groups of newborns.Conclusions: The comparison of the results of both groups of newborns indicates a development in the interaction between cortical, thalamocortical and neurovegetative structures in the neonatal brain.

Published: May 2014

ABSTRACT
Constant exotropia is uncommon during the first year of life. We retrospectively identified 13 patients with large, constant exotropia during the first year of life which required surgery. Bilateral lateral rectus muscle recessions were done in all 13 cases. Only two patients have required reoperation. The clinical characteristics and management of this unusual condition are similar to those of infantile esotropia.

Abstract

Despite initial response to therapy, most acute myeloid leukemia (AML) patients relapse. To eliminate relapse-causing leukemic stem/progenitor cells (LPCs), patient-specific immune therapies may be required. In vitro cellular engineering may require increasing the “stemness” or immunogenicity of tumor cells and activating or restoring cancer-impaired immune-effector and antigen-presenting cells. Leukapheresis samples provide the cells needed to engineer therapies: LPCs to be targeted, normal hematopoietic stem cells to be spared, and cancer-impaired immune cells to be repaired and activated. This study sought to advance development of LPC-targeted therapies by exploring nongenetic ways to slow the decay and to increase the immunogenicity of primary CD34+ AML cells. CD34+ AML cells generally displayed more colony-forming and aldehyde dehydrogenase activity than CD34− AML cells. Along with exposure to bone marrow stromal cells and low (1%–5%) oxygen, culture with RepSox (a reprogramming tool and inhibitor of transforming growth factor-β receptor 1) consistently slowed decline of CD34+ AML and myelodysplastic syndrome (MDS) cells. RepSox-treated AML cells displayed higher CD34, CXCL12, and MYC mRNA levels than dimethyl sulfoxide-treated controls. RepSox also accelerated loss of T cell immunoglobulin mucin-3 (Tim-3), an immune checkpoint receptor that impairs antitumor immunity, from the surface of AML and MDS cells. Our results suggest RepSox may reduce Tim-3 expression by inhibiting transforming growth factor-β signaling and slow decay of CD34+ AML cells by increasing CXCL12 and MYC, two factors that inhibit AML cell differentiation. By prolonging survival of CD34+ AML cells and reducing Tim-3, RepSox may promote in vitro immune cell activation and advance development of LPC-targeted therapies.
L’intervention de quartier à Sherbrooke, ou quand le CLSC s’installe à la porte d’à côté
Authors: Morin Paul , Benoît Maryse , Dallaire Nicole , Doré Chantal , LeBlanc Jeannette 
Published: May 2014

Le texte décrit et analyse les pratiques d’intervention de quartier (IQ) telles qu’elles se sont déployées dans leurs contextes particuliers, pour ensuite mettre en lumière les effets perçus par les diverses parties prenantes (intervenants, partenaires du milieu, gestionnaires). Les deux territoires d’intervention (Ascot et Jardins-Fleuris) ont la particularité d’être parmi les plus défavorisés de Sherbrooke tout en ayant une forte densité de population. Le modèle logique opérationnel d’intervention se traduit par cinq orientations : 1) tenir compte des particularités des personnes et des milieux, 2) agir dans la proximité, 3) intervenir de façon proactive, 4) favoriser une dimension relationnelle et 5) réguler de façon continue l’intervention. De fait, l’intervention clinique et communautaire s’articule entre elles sur un territoire, ce qui constitue la grande originalité du projet d’intervention. L’évaluation des résultats de cette initiative est très positive et peut constituer une source d’inspiration.
La négociation d’une entente collective en marge du Code du travail : le cas d’un collège privé
Authors: Gagnon Mélanie , Le Capitaine Catherine 
Published: May 2014

Cet article, qui prend appui sur une étude de cas menée dans un collège secondaire privé du Québec, s’intéresse à la représentation non syndicale en se penchant sur le processus de négociation d’une entente en marge du régime général. La présente contribution a pour objet de comprendre les motifs pour lesquels un groupe de travailleurs, de concert avec l’employeur, emprunte cette avenue ayant pour dessein la signature d’une entente de travail. Ce cas de représentation non syndicale, étudié à partir d’une diversité de sources de données, met en évidence que le mode de représentation initié par l’employeur s’inscrit dans la thèse de l’évitement syndical.
Ainsi, la reconnaissance d’un regroupement d’enseignants et la négociation volontaire de la part de l’employeur sont directement liées au désir d’éviter la syndicalisation. Du côté des enseignants, le choix de demeurer dans un regroupement non reconnu repose essentiellement sur la qualité des relations avec la direction et sur le désir d’avoir un mode de représentation exempt de conflits. Les enseignants sont, dans une large proportion, satisfaits des termes de l’entente de travail, d’autant plus qu’ils bénéficient de plusieurs avantages négociés par le personnel enseignant syndiqué du Québec. Il ressort des résultats que le regroupement n’est pas sous le joug de l’idéologie managériale, mais son pouvoir d’influencer les décisions est plutôt lacunaire. Cette entente, qui ne repose que sur le contexte particulier, la confiance mutuelle et la crainte de syndicalisation, comporte des limites importantes en termes d’application.
The Transformation of Employment Regulation in Greece: Towards a Dysfunctional Liberal Market Economy?
Authors: Kornelakis Andreas , Voskeritsian Horen 
Published: May 2014

Since the eruption of the European sovereign debt crisis, the bailout conditions imposed on Greece have gradually shifted their emphasis from ‘‘tidying up” public finances towards ‘‘improving the competitiveness” of the economy. In the process, collective bargaining has been targeted as one of the priority areas for reform, which resulted in a gradual dismantling of the system. The main aim of this article is to analyse the changes in the institutional framework of employment regulation, using insights from the varieties of capitalism literature. It is argued that the on-going injection of liberal market elements into the Greek employment system is likely to transform Greece into a dysfunctional Liberal Market Economy.
The changes in the collective regulation of employment ignore the specificities and idiosyncrasies of the Mediterranean model of capitalism and, thus, are likely to leave the country with the ‘‘worst of both worlds”: suboptimal economic performance and diluted social cohesion. The article is structured as follows. First, the debate on varieties of capitalism is considered in light of the Global Crisis. Second, the basic features of the Greek employment relations’ model are discussed. Third, the transformation of employment regulation after the bailout is examined. Fourth, the evolution towards a dysfunctional Liberal Market Economy is analysed. The final section concludes.
La reconnaissance du capital immatériel : quels enjeux pour l’évaluation des entreprises ?
Authors: Bessieux-Ollier Corinne , Schatt Alain , Walliser Elisabeth , Zéghal Daniel 
Published: May 2014

Le capital immatériel a pris une importance croissante dans de nombreuses entreprises, mais les règles comptables ne permettent généralement pas de faire figurer ses composantes dans les états financiers publiés en fin d’année. Cet article se focalise sur les conséquences de la normalisation comptable actuelle sur l’évaluation des entreprises. Il discute également du rôle des informations extra comptables sur les actifs immatériels, divulguées volontairement par les entreprises pour aider les investisseurs à évaluer les entreprises. Enfin, le rôle des analystes financiers est évoqué : leur expertise devient essentielle pour apprécier l’impact du capital immatériel sur le devenir des entreprises et, par conséquent sur leur valeur.
High‐level soluble expression of Serratia marcescensH30 lipase in Escherichia coli
Authors: Su Erzheng , Xu Jingjing , Wu Xiangping 
Published: May 2014

AbstractSerratia marcescens lipase (SmL) is an important biocatalyst used to enantioselectively hydrolyze (±)‐trans‐3‐(4‐methoxyphynyl) glycidic acid methyl ester. However, the economically justified level recombinant soluble expression of SmL in Escherichia coli has not been established. Thus, fusion genes of lipase from S. marcescens H30 with different fusion tags were constructed and expressed in E. coli. The effects of fusion tags were revealed. A significant increase in recombinant lipase solubility showed that E. coli BL21 (DE3)/pET32a‐SmL was a suitable choice for SmL production. To optimize the performance of recombinant SmL production, changes in culture medium compositions and induction conditions were systematically tested. Finally, the recombinant SmL activity and productivity reached approximately 23,000 U/L and 1,278 U/L/H in shake flasks, respectively. This value is the highest SmL activity attained by heterogeneous recombinant expression in E. coli. Lipase activity and productivity reached 19,650 U/L and 1,228 U/L/H, respectively, by scaling up SmL production in a 7.0 L fermenter. The existence of the Trx tag did not influence the chiral selectivity of recombinant SmL. These findings indicate a possibility for soluble and economical SmL expression in E. coli to meet industrial needs.
Investigating the genetic polymorphism of sheep milk proteins: a useful tool for dairy production
Authors: Selvaggi Maria , Laudadio Vito , Dario Cataldo , Tufarelli Vincenzo 
Published: May 2014

AbstractSheep is the second most important dairy species after cow worldwide, and especially in the Mediterranean and Middle East regions. In some countries, the difficult environmental conditions require a peculiar adaptation and, in these contexts, sheep are able to provide higher quality protein than cattle. In the least‐developed countries, the amount of dairy sheep and ovine milk production is progressively increasing. In order to improve dairy productions, in particular those with local connotations, it is necessary to obtain in‐depth information regarding milk quality and rheological properties. The genetic polymorphisms of milk proteins are often associated with quantitative and qualitative parameters in milk and are potential candidate markers that should be included in breeding strategies similar to those already available for cattle. Due to the current and growing interest in this topic and considering the large amount of new information, the aim of this study was to review the literature on sheep milk protein polymorphisms with a particular emphasis on recent findings in order to give scientists useful support. Moreover, the effects of different protein variants on milk yield and composition are discussed. © 2014 Society of Chemical Industry
The Parkinson Anxiety Scale (PAS): Development and validation of a new anxiety scale

Published: May 2014

ABSTRACTExisting anxiety rating scales have limited construct validity in patients with Parkinson's disease (PD). This study was undertaken to develop and validate a new anxiety rating scale, the Parkinson Anxiety Scale (PAS), that would overcome the limitations of existing scales. The general structure of the PAS was based on the outcome of a Delphi procedure. Item selection was based on a canonical correlation analysis and a Rasch analysis of items of the Hamilton Anxiety Rating Scale (HARS) and the Beck Anxiety Inventory (BAI) from a previously published study. Validation was done in a cross‐sectional international multicenter study involving 362 patients with idiopathic PD. Patients underwent a single screening session in which the PAS was administered, along with the Hamilton Depression Rating Scale, the HARS, and the BAI. The Mini International Neuropsychiatric Interview was administered to establish Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnoses of anxiety and depressive disorders. The PAS is a 12‐item observer or patient‐rated scale with three subscales, for persistent, episodic anxiety and avoidance behavior. Properties for acceptability and reliability met predetermined criteria. The convergent and known groups validity was good. The scale has a satisfactory factorial structure. The area under the receiver operating characteristics curve and Youden index of the PAS are higher than that of existing anxiety rating scales. The PAS is a reliable and valid anxiety measure for use in PD patients. It is easy and brief to administer, and has better clinimetric properties than existing anxiety rating scales. The sensitivity to change of the PAS remains to be assessed. © 2014 International Parkinson and Movement Disorder Society

ObjectivePeripheral lower body fat is associated with lower cardiometabolic risk. Physiological differences in gluteal compared with abdominal subcutaneous (sc) adipocyte functions are known but the molecular basis for depot differences in adipocyte function is poorly understood. Our goal is to identify novel gene regulatory pathways that underlie the heterogeneity of human fat distribution.MethodsAbdominal and gluteal adipose tissue aspirates obtained from 35 subjects (age = 30 ± 1.6 years; BMI = 27.3 ± 1.3 kg/m2) were analyzed using Illumina microarrays and confirmed by RT‐PCR. The HOTAIR gene was stably transfected into primary cultured human abdominal sc preadipocytes using a lentivirus and effects on adipogenic differentiation were analyzed.ResultsA long noncoding RNA, HOTAIR that was expressed in gluteal but not in Abd sc adipose tissue was identified. This difference was retained throughout in vitro differentiation and was maximal at day 4. Ectopic expression of HOTAIR in abdominal preadipocytes produced an increase in differentiation as reflected by a higher percentage of differentiated cells, and increased expression of key adipogenic genes including PPARγ and LPL.ConclusionsHOTAIR is expressed in gluteal adipose and may regulate key processes in adipocyte differentiation. The role of this lncRNA in determining the metabolic properties of gluteal compared with abdominal adipocytes merits further study.

Published: May 2014

RATIONALEBecause of the threat of bombings using improvised explosives containing ammonium nitrate (AN), law enforcement and intelligence communities have been interested in stable isotope techniques for tracking and discriminating AN sources. Separate analysis of the AN component ions ammonium and nitrate would add discriminatory power to these techniques.METHODSAmmonium ions in dissolved AN solution were isolated from samples by precipitation using sodium tetraphenylborate solution. We tested the isolation of ammonium from nitrates using solutions of ammonium and nitrate salts with different 15N/14N isotope ratios. Ammonium tetraphenylborate and AN were separately analyzed for their 15N/14N isotope ratios using EA‐ConFlo‐IRMS, and the 15N/14N isotope ratios of the nitrate ions were calculated using mass balance. Ammonium and nitrate nitrogen isotope ratios were plotted as two separate variables.RESULTSIsolation of ammonium precipitate from solutions containing dissolved nitrates did not influence the nitrogen isotope ratios of test ammonium salts. A survey set of 42 AN samples showed that the ammonium and nitrate 15N/14N isotope ratios were not significantly correlated, and the paired mean differences were not statistically significant. Both ammonium and nitrate were depleted in 15N relative to their theoretical atmospheric sources.CONCLUSIONSIsolation of the ammonium ion from AN adds another dimension for the discrimination of forensic AN samples. This technique using sodium tetraphenylborate is robust and does not require specialized equipment. Our observations indicated that ammonium nitrogen and nitrate nitrogen have independent sources of isotopic variation. Copyright © 2014 John Wiley & Sons, Ltd.
Personality Disturbances in Amyotrophic Lateral Sclerosis: A Case Study Demonstrating Changes in Personality Without Cognitive Deficits
Authors: Waldron Eric J. , Barrash Joseph , Swenson Andrea , Tranel Daniel 
Published: May 2014

AbstractPatients with amyotrophic lateral sclerosis (ALS) often show deficits on neuropsychological tests that tap functions related to the integrity of the prefrontal lobes. Various aspects of personality are also known to be mediated by prefrontal regions, particularly ventromedial prefrontal cortex (vmPFC). Other than apathy, personality changes have not been widely reported in patients with ALS, although clinical observations indicate such changes might be relatively common. Here, we report on a middle-aged woman with bulbar onset ALS (diagnosed 06/2011, examined in Spring, 2012) whose neuropsychological exam did not reveal cognitive deficits. She performed normally on tests of executive functioning. Self-report measures of mood and personality were unremarkable. However, significant personality changes subsequent to disease onset were reported by her husband and two daughters, and these changes were quantified with the Iowa Scales of Personality Change. Results show that personality disturbance may manifest in the absence of notable cognitive changes in ALS, and careful assessment of personality may be important for documenting early neurobehavioral changes in some ALS patients. Findings also show that patients with ALS may not have good insight into personality changes, underscoring the importance of acquiring collateral information. More generally, the results provide further evidence that ALS may compromise the integrity of ventromedial prefrontal regions. (JINS, 2014, 20, 1–8)
