New SPME fibre for analysis of mequinol emitted from DVDs
Authors: Palacz Magdalena , Wasiak Wiesław 
Published: January 2011

AbstractA piece of fused-silica fibre coated with silica modified with ketamine-groups was used as a solidphase microextraction (SPME) fibre and its efficiency in the qualitative and quantitative analysis of volatile organic compounds released from coloured overprinting on DVDs was evaluated. The effect of the parameters that can affect the SPME procedure, such as extraction time, extraction temperature, desorption temperature, was investigated to determine the analytical performance of this novel fibre in the qualitative and quantitative analyses of organic compounds. The optimised procedure was applied to the qualitative and quantitative analyses of organic compounds released from coloured overprinting on DVDs. The limit of detection of 4-methoxyphenol (mequinol) was 88 × 10−3 μg mL−1, while the limit of quantification (LOQ) was calculated as ten times the baseline noise, i.e. 3.1 × 10−1 μg mL−1. The proposed fibre was used successfully for preconcentration of the volatile organic compounds from the gaseous phase of DVD samples.

Authors: Eshaghi Gordji M. , Ghobadipour N. 
Published: January 2011

Abstract
Let A be an algebra and let X be an A-bimodule. A ∂-linear mapping d: A → X is called a generalized Jordan derivation if there exists a Jordan derivation (in the usual sense) δ: A → X such that d(a
2) = ad(a)+δ(a)a for all a ∈ A. The main purpose of this paper is to prove the Hyers-Ulam-Rassias stability and superstability of the generalized Jordan derivations.

Published: January 2011

Abstract
We introduce an order relation in the set of modular biweights on a Banach C*-module X and give a description of this order relation in terms of representation associated with each modular biweight by GNS construction. We also characterize the extreme points in the set of all biweights φ defined on X such that φ(x
0, x
0) = λ
0. Furthermore, we discuss operator representations associated with modular biweights on Banach C*-modules.

Exploring Candidate Genes for Epilepsy by Computational Disease-Gene Identification StrategyEpilepsy is a complex disease with a strong genetic component. So far, studies have focused on experimental validation or genome-wide linkage scans for epilepsy susceptibility genes in multiple populations. We have used four bioinformatic tools (SNPs3D, PROSPECTR and SUSPECTS, GenWanderer, PosMed) to analyze 16 susceptibility loci selected from a literature search. Pathways and regulatory network analyses were performed using the Ingenuity Pathways Analysis (IPA) software. We identified a subset of 48 candidate epilepsy susceptibility genes. Five significant canonical pathways, in four typical networks, were identified: GABA receptor signaling, interleukin-6 (IL-6) signaling, G-protein coupled receptor signaling, type 2 diabetes mellitus signaling and airway inflammation in asthma. We concluded that online analytical tools provide a powerful way to reveal candidate genes which can greatly reduce experimental time. Our study contributes to further experimental tests for epilepsy susceptibility genes.

Apoptosis Gene Expression Profile in Early-Stage non Small Cell Lung CancerNon small cell lung cancer (NSCLC) is a highly aggressive malignancy with survival rates limited to some patients in early stages (I and II). Apoptosis resistance is a hallmark of solid tumors that is tightly concerned with their biology. We analyzed the expression of 84 apoptosis-related genes in a group of Bulgarian patients with early-stage NSCLC.RNA samples extracted from 12 early-stage NSCLC patients [five squamous cell carcinomas (SCC) and seven adenocarcinomas (AC)] and eight adjacent non neoplastic pulmonary tissues were used for gene expression analysis. We applied pathway-focused expression profiling of 84 apoptosis-related genes using real-time PCR.Apoptosis-related genes down regulated in NSCLC compared to non tumor lung tissue (p <0.05) included representatives of the tumor necrosis factor (TNF) ligand family [TNF superfamily 8 (TNFSF8)], caspase cascade (CASP8 and CASP10) and caspase recruitment domain (CARD) family (BCL10), the positive apoptosis regulator DAPK1 and BCL2 family member MCL1. The potential of apoptosis-related genes as prognostic and predictive markers should be validated in future studies.

Implementation of Cryptographic Algorithms in Software: An Analysis of the Effectiveness
The goal of the paper is to discuss some possibilities of effective implementing cryptographic algorithms in software development. There are concerned two aspects of the term "effectiveness": efficacy (i.e., meeting a goal of using cryptographic algorithms - providing a protection of information) and efficiency (i.e., implementing cryptographic algorithms in an economical way; as well as implementing cryptographic algorithms to the effect that they execute in an economical way). In the paper, there are defined and classified errors which are the causes of possible vulnerabilities in implementation of cryptographic algorithms on a computer. There are given general recommendations, how to escape from these vulnerabilities. There is also considered implementation of cryptographic algorithms in software development by using software libraries and frameworks. Several widespread software frameworks which provide cryptographic functionality are compared with each other by the speed of execution of algorithms. Finally, there are discussed some possibilities of maximising the speed of execution of cryptographic algorithms, emphasising the importance of parallelisation of algorithms. For block ciphers, possible parallelisation is discussed especially deeply, referencing the results obtained in practical experiments that demonstrate and estimate the benefits of parallelising block ciphers.

Searching the Damaged Outgoing Feeder in Networks with Insulated Neutral by Phase-to-ground Fault
Authors: Sivokobylenko Vitaliy , Kuzmenko Dmitriy 
Published: January 2011

Searching the Damaged Outgoing Feeder in Networks with Insulated Neutral by Phase-to-ground FaultThe method of searching the damaged feeder was improved by alternate disconnecting of feeder circuit-breakers, which allow to enlarge reliability of the systems of power supply by diminishing the number of multiple earth fault in electric network. Diminishing the number of multiple earth faults is attained by exception of switching overvoltage, because commutations of feeder circuit-breakers are carrying out when shunting circuit breaker is closed. The detection of damage in the feeder, when this method is used, is produced on the change of phase of current in the circuit of shunting circuit breaker after disconnecting of circuit-breaker of this feeder.
Least Squares Spectral Analysis for Detection of Systematic Behaviour of Digital Level Compensator

Published: January 2011

Least Squares Spectral Analysis for Detection of Systematic Behaviour of Digital Level CompensatorLevelling is the most precise technique for height difference measurements in geomatics engineering. Various systematic errors affect precise levelling observations and reduce the precision of the observed height differences. This study investigates digital levels residual compensator error and observational method for its elimination. For this purpose the levelling data, which was collected with Zeiss DiNi 12 digital levels, was analysed. There are different statistical and spectral methods that can reveal the presence of systematic errors in levelling results. In this study, the Least Squares Spectral Analysis (LSSA) method is used. The analysis confirmed that using alternating pointing method (BFFB, FBBF) instead of usual observation routine (BFFB) will eliminate the Zeiss DiNi 12 digital levels residual compensator error from section height differences and discrepancies. In this way, it does not matter using different instruments in the forward and backward section runs and the discrepancies can be used to investigate other systematic errors.

Published: January 2011

Objective: The aim of the current study was to investigate gender differences with respect to pre-treatment characteristics, clinical presentation, service utilization and functional outcome in patients presenting with first-episode psychosis. Methods: A total of 700 participants (men, n = 360; women, n = 340) aged 15 to 25 years consecutively enrolled in a territory-wide first-episode psychosis treatment programme in Hong Kong from July 2001 to August 2003 were studied. Baseline and three-year follow up variables were collected via systematic medical file review. Results: At service entry, men had significantly lower educational attainment (p < 0.01), longer median duration of untreated psychosis (p < 0.001), fewer past suicidal attempts (p < 0.01), more severe negative symptoms (p < 0.05) and fewer affective symptoms (p < 0.01) than women. There was no significant gender difference in age of onset. In three-year follow up, men had more prominent negative symptoms (p < 0.001), fewer affective symptoms (p < 0.01), more violent behaviour and forensic records (p < 0.01), and higher rate of substance abuse (p < 0.01). Women achieved higher levels of functioning than men (Social Occupational Functioning Assessment Scale (SOFAS), p < 0.001) and a significantly higher proportion of women than men engaged in full-time employment or study for at least 12 consecutive months (p < 0.001) in the initial three years after psychiatric treatment. Conclusion: Notable gender differences in clinical profiles, illness trajectory and functional outcome were demonstrated in Chinese young people suffering from first-episode psychosis. Differential needs between men and women and hence gender-specific therapeutic strategies should be considered in early intervention service.
Le « Cancionero General » de 1511 et ses trente-huit romances
Authors: Aubrun Charles Vincent 
Published: January 2011

El Cancionero general de 1511 y sus treinta y ocho romances.
Dans le Cancionero General (1509-1511) figure une section de romances. Ce sont au total 38 pièces, dont l'une est rimée aabbcc..., ce qui pose le problème de la définition contemporaine du sous-genre. Il y a là cinq pièces de circonstance et quelques gracieux poèmes, tenus pour de « vieux » romances, qui doivent remonter à trente années tout au plus. Mais la plupart des pièces sont allégoriques ou conceptuelles et signées par des poètes particulièrement raffinés, pour la plupart arago- nais, c'est-à-dire catalans et valenciens. Certains incipit renvoient à des légendes épiques dont nous ignorons la forme. La matière de Bretagne apparaît ainsi que des « histoires » tirées de vieux ouvrages toujours actuels (Alexandre, Troie...). La matière carolingienne sous forme narrative est absente. Le compilateur Hernando del Castillo ne connaît pas les romances des pliegos sueltos postérieurs.
Sur quelques caractères physico-chimiques d'eaux karstiques languedociennes et leur influence dans la géomorphogenèse actuelle
Authors: Fabre Guilhem 
Published: January 2011

ABSTRACT
With the example of karstic springs near by Uzès (Eastern Bas-Languedoc, SE of Frence) the author shows that waters chimical composition is constant all during the hydrologie cycle. The Ca++ ion stands always between 5,6 and 6,7 meq /I. These values rise with the discharge fall and on the contrary. Chimical analysis reveals an important control exercised by the alimentation basin. Theoritical agressivily reckoning with H. Roques's curves shows that waters are agressive at the springs but they become rapidly saturated downstream, chiefly during hot periods.
La région du Padis (Monts Apuseni, Roumanie)
Authors: Ficheux Robert 
Published: January 2011

SUMMARY
The Padis region is an original karstical territory in a complex of mesozoïcal formations (trias bis jura) lying upon a cristallin substratum. But its particular topography was born on a hydrographie net, itself chiseled during several periods or stages of hollowing and levelling, between 1 050 and 1 400 m above sea-level. Today three rivers are collecting the subterranean waters which have sunk in the ground all along the ancient and mature valleys of these inner- surfaces.

Une karstification d'origine biologique : cuvettes et lapiés sur le littoral calcaire du Burren (Irlande Occidentale)
Authors: Coudé Armel 
Published: January 2011

SUMMARY
The various dints and pans of the calcareous shore of the Burren ( Western Ireland) are the habitat of original flora and fauna, then again the result of a chemical and biological corrosion. Five bio-geomorphological levels rise between the highest sea-spray zone and the lowest Laminaria zone. This theoretical zonation is diversified by exposure and steep slope. The biological especially animal-karstificalion becomes important on the western shore. The later and actual coastal evolution can be determined by these minor features.

The thick quartzilic stratas laying on the Guianese Shield often show a genuine karstic morphology. The Auyan Tepui, for instance, in Venezuela, is so fissured that water flows inside and pours out as hanging cascades, the upper ones acting only during the rainy season.
Du bon usage de la dénégation
Authors: Maruani Guy 
Published: January 2011

Résumé Psychanalyse et systémique revendiquent des références conceptuelles distinctes voire opposées. À la suite de Sigmund Freud, la thérapie psychanalytique se concentre sur l’Inconscient et sur la levée du refoulement dans une approche intra-psychique. À la suite de Paul Watzlawick, la systémique s’occupe du contexte et des situations vécues dans une approche interactionnelle. Mais comme il n’y a qu’une seule réalité, comme toute thérapie est une interaction qui joue sur des niveaux logiques de discours, il s’avère que psychanalyste ou systémicien, le thérapeute doit dégager le patient de la résistance, c’est-à-dire des affects qui encombrent sa pensée, ce qu’il n’obtient qu’au prix d’une stratégie identique de dénégation. En fait le thérapeute est un « bel indifférent ».
“Open as to people”: the people's response to the Open University of the United Kingdom 1971-2009
Authors: Woodley Alan 
Published: January 2011

Résumé L’auteur interroge quarante ans d’inscriptions à l’Université Ouverte (Open University, OU), créée en 1971. En inscrivant, selon le principe du premier arrivé-premier servi, toute personne de 21 ans (puis de 18 et enfin de 16) vivant au Royaume-Uni, sans exigence de qualification, l’OU est-elle parvenue à accroître l’accès au supérieur de ceux qui n’y entraient pas ? Comparativement aux autres, l’OU a en effet attiré plus d’étudiants n’ayant pas les pré-requis habituels pour entrer dans le supérieur ou appartenant à des classes sociales écartées jusque-là. Ils ont en moyenne dix à quinze ans de plus que les étudiants traditionnels et ont interrompu leurs études à la fin du secondaire. L’enquête révèle aussi les difficultés méthodologiques de la mesure d’une telle ouverture. Par exemple, quelle référence prendre, la classe sociale des parents ou celle de l’étudiant lui-même puisqu’il est plus âgé ? Conçue pour offrir une seconde chance, l’OU accueille aujourd’hui davantage de jeunes étudiants –écartés par l’augmentation des droits d’inscription en Université, ce qui souligne la fragilité des résultats encourageants obtenus. Une politique gouvernementale peut tout inverser rapidement. Des recherches sont aussi nécessaires sur les résultats universitaires comparés des étudiants de l’OU.
Faire une pause ou bifurquer ? Essai de typologie des trajectoires de formation
Authors: Pollien Alexandre 
Published: January 2011

Résumé Cette analyse de l’évolution de la formation en Suisse s’appuie sur la forme des itinéraires suivis. La typologie construite permet de mesurer l’évolution, sur près de soixante-dix ans, des trajectoires empruntées selon l’origine sociale et de montrer l’émergence de nouveaux parcours. Les données attestent un accroissement des parcours atypiques, à cheval sur plusieurs filières, comportant des interruptions ou composés de formations complémentaires. Plus qu’à une égalisation du niveau d’éducation, on assiste à une inflation des diplômes, caractérisée par une multiplication des périodes de formations tardives, plutôt mesurable à la complexification des parcours qu’au niveau final atteint. On peut donc faire l’hypothèse que ce n’est plus le diplôme atteint qui détermine la valeur de la formation suivie mais le nombre et la pertinence des reformations.
Évaluation et accompagnement des établissements en Europe : diversité et mécanismes d'hybridation
Authors: Dumay Xavier 
Published: January 2011

Résumé Depuis une vingtaine d’années, les politiques éducatives des systèmes scolaires européens ont connu des transformations substantielles. D’ordre structurel et cognitif, elles s’organisent autour d’une redistribution des pouvoirs entre centre et périphérie et d’une prise en compte accrue des effets des systèmes scolaires. L’objectif est ici de montrer –à partir d’une analyse comparée de l’évolution des processus d’évaluation et d’accompagnement des établissements d’enseignement en Suède et en Angleterre– qu’au-delà des convergences repérables, ces politiques comportent un caractère spécifique et irréductible aux modèles transnationaux d’éducation émergents. L’analyse comparée des deux systèmes ouvre ainsi une discussion sur les critères de diversité des politiques du rendre compte (accountability) dans l’espace européen. Elle est organisée autour de trois axes : les théories de la régulation et du changement sous-jacentes, la signification des processus de décentralisation/centralisation et la transformation des représentations légitimes des systèmes scolaires accompagnant ces transformations politiques.
Temps et aspect dans le commentaire des illustrations d’articles de recherche en informatique
Authors: Labrosse Pierre 
Published: January 2011

Selon L. Trimble (1985 : 125), l’auteur emploie le présent pour discuter de l’illustration et de sa relation avec le sujet abordé dans l’article. On constate cependant, dans les articles de recherche en informatique, qu’il utilise aussi le prétérit et le present perfect. Nous montrons tout d’abord que les conditions de l’emploi de ces trois temps respectent leur valeur en langue et étudions ensuite l’influence de la fonction rhétorique de commentaire d’une illustration sur ces constituants. L’utilisation des temps qui y est faite diffère donc de celle que l’on peut observer dans la description de l’obtention des informations de l’illustration. Nous terminons avec un paradoxe : les formes en be + ing sont absentes alors qu’elles soulignent typiquement une distance entre l’énoncé et la réalité, écart favorable au commentaire.
Fascin1 Promotes Cell Migration of Mature Dendritic Cells

Published: January 2011

AbstractDendritic cells (DCs) play central roles in innate and adaptive immunity. Upon maturation, DCs assemble numerous veil-like membrane protrusions, disassemble podosomes, and travel from the peripheral tissues to lymph nodes to present Ags to T cells. These alterations in morphology and motility are closely linked to the primary function of DCs, Ag presentation. However, it is unclear how and what cytoskeletal proteins control maturation-associated alterations, in particular, the change in cell migration. Fascin1, an actin-bundling protein, is specifically and greatly induced upon maturation, suggesting a unique role for fascin1 in mature DCs. To determine the physiological roles of fascin1, we characterized bone marrow-derived, mature DCs from fascin1 knockout mice. We found that fascin1 is critical for cell migration: fascin1-null DCs exhibit severely decreased membrane protrusive activity. Importantly, fascin1-null DCs have lower chemotactic activity toward CCL19 (a chemokine for mature DCs) in vitro, and in vivo, Langerhans cells show reduced emigration into draining lymph nodes. Morphologically, fascin1-null mature DCs are flatter and fail to disassemble podosomes, a specialized structure for cell-matrix adhesion. Expression of exogenous fascin1 in fascin1-null DCs rescues the defects in membrane protrusive activity, as well as in podosome disassembly. These results indicate that fascin1 positively regulates migration of mature DCs into lymph nodes, most likely by increasing dynamics of membrane protrusions, as well as by disassembling podosomes.
