Authors: Holden Kisha , Akintobi Tabia , Hopkins Jammie , Belton Allyson , McGregor Brian , Blanks Starla , Wrenn Glenda
Published: December 2015

Health is a human right. Equity in health implies that ideally everyone should have a fair opportunity to attain their full health potential and, more pragmatically, that no one should be disadvantaged from achieving this potential. Addressing the multi-faceted health needs of ethnically and culturally diverse individuals in the United States is a complex issue that requires inventive strategies to reduce risk factors and buttress protective factors to promote greater well-being among individuals, families, and communities. With growing diversity concerning various ethnicities and nationalities; and with significant changes in the constellation of multiple of risk factors that can influence health outcomes, it is imperative that we delineate strategic efforts that encourage better access to primary care, focused community-based programs, multi-disciplinary clinical and translational research methodologies, and health policy advocacy initiatives that may improve individuals’ longevity and quality of life.

Authors: Oh Hyun-Mi , Park Joo , Song Dae , Chung Myung
Published: December 2015

MT10107 is botulinum neurotoxin type A derived drug which utilizes the 150 kDa portion without complexing proteins and human serum albumin contents. To evaluate the efficacy and the safety of MT10107, it was compared with onabotulinumtoxinA in this double-blind, randomized controlled trial. Twenty-five healthy males received a randomly selected dose of MT10107 into the extensor digitorum brevis (EDB) muscle of one foot, and an equivalent dose of onabotulinumtoxinA (BOTOX) was injected into the contralateral EDB muscle. While efficacy of the administered substance was determined by measuring paretic effects on the EDB, the local spread of toxin effects was evaluated by the paretic effects on the nearby abductor hallucis (AH) and abductor digiti quinti (ADQ) muscles. Paretic effects were defined as the percentage of reduction of the compound muscle action potential (CMAP) amplitudes, measured at 14, 30, 90 days after the injection, compared to the baseline value. Intergroup (MT10107 and onabotulinumtoxinA) differences were not significant in the percentage reduction of the amplitudes in the EDB muscles. In this study, there was no significant difference in efficacy and safety between the two test drugs. MT10107 may be effective and safe as much as onabotulinumtoxinA to produce the desired paretic effect.
Exploring Reovirus Plasticity for Improving Its Use as Oncolytic Virus
Authors: Kemp Vera , Hoeben Rob , Van den Wollenberg Diana
Published: December 2015

Reoviruses are non-enveloped viruses with a segmented double stranded RNA genome. In humans, they are not associated with serious disease. Human reoviruses exhibit an inherent preference to replicate in tumor cells, which makes them ideally suited for use in oncolytic virotherapies. Their use as anti-cancer agent has been evaluated in several clinical trials, which revealed that intra-tumoral and systemic delivery of reoviruses are well tolerated. Despite evidence of anti-tumor effects, the efficacy of reovirus in anti-cancer monotherapy needs to be further enhanced. The opportunity to treat both the primary tumor as well as metastases makes systemic delivery a preferred administration route. Several pre-clinical studies have been conducted to address the various hurdles connected to systemic delivery of reoviruses. The majority of those studies have been done in tumor-bearing immune-deficient murine models. This thwarts studies on the impact of the contribution of the immune system to the tumor cell eradication. This review focuses on key aspects of the reovirus/host-cell interactions and the methods that are available to modify the virus to alter these interactions. These aspects are discussed with a focus on improving the reovirus’ antitumor efficacy.
HTLV-1, Immune Response and Autoimmunity
Authors: Quaresma Juarez , Yoshikawa Gilberto , Koyama Roberta , Dias George , Fujihara Satomi , Fuzii Hellen
Published: December 2015

Human T-lymphotropic virus type-1 (HTLV-1) infection is associated with adult T-cell leukemia/lymphoma (ATL). Tropical spastic paraparesis/HTLV-1-associated myelopathy (PET/HAM) is involved in the development of autoimmune diseases including Rheumatoid Arthritis (RA), Systemic Lupus Erythematosus (SLE), and Sjögren’s Syndrome (SS). The development of HTLV-1-driven autoimmunity is hypothesized to rely on molecular mimicry, because virus-like particles can trigger an inflammatory response. However, HTLV-1 modifies the behavior of CD4+ T cells on infection and alters their cytokine production. A previous study showed that in patients infected with HTLV-1, the activity of regulatory CD4+ T cells and their consequent expression of inflammatory and anti-inflammatory cytokines are altered. In this review, we discuss the mechanisms underlying changes in cytokine release leading to the loss of tolerance and development of autoimmunity.
An Integrated Framework for Assessment of Hybrid Water Supply Systems
Authors: Sapkota Mukta , Arora Meenakshi , Malano Hector , Moglia Magnus , Sharma Ashok , George Biju , Pamminger Francis
Published: December 2015

Urban water managers around the world are adopting decentralized water supply systems, often in combination with centralized systems. While increasing demand for water arising from population growth is one of the primary reasons for this increased adoption of alternative technologies, factors such as climate change, increased frequency of extreme weather events and rapid urbanization also contribute to an increased rate of adoption of these technologies. This combination of centralized-decentralized water systems approach is referred to as “hybrid water supply systems” and is based on the premise that the provision of alternative water sources at local scales can both extend the capacity of existing centralized water supply infrastructures, and improve resilience to variable climatic conditions. It is important to understand, however, that decentralized water production and reuse may change the flow and composition of wastewater and stormwater, thereby potentially also having negative impacts on its effectiveness and performance. This paper describes a framework to assess the interactions between decentralized water supply systems and existing centralized water servicing approaches using several analytical tools, including water balance modelling, contaminant balance modelling and multi-criteria decision analysis. The framework enables the evaluation of impacts due to change in quantity and quality of wastewater and stormwater on the existing centralized system arising from the implementation of hybrid water supply systems. The framework consists of two parts: (1) Physical system analysis for various potential scenarios and (2) Ranking of Scenarios. This paper includes the demonstration of the first part of the framework for an area of Melbourne, Australia by comparing centralized water supply scenario with a combination of centralized water supply and reuse of treated waste water supply scenario.
Tumour exosomes display differential mechanical and complement activation properties dependent on malignant state: implications in endothelial leakiness

Published: December 2015

Background

Exosomes have been implicated in tumour progression and metastatic spread. Little is known of the effect of mechanical and innate immune interactions of malignant cell‐derived exosomes on endothelial integrity, which may relate to increased extravasation of circulating tumour cells and, therefore, increased metastatic spread.

Methods

Exosomes isolated from non‐malignant immortalized HCV‐29 and isogenic malignant non‐metastatic T24 and malignant metastatic FL3 bladder cells were characterized by nanoparticle tracking analysis and quantitative nanomechanical mapping atomic force microscopy (QNM AFM) to determine size and nanomechanical properties. Effect of HCV‐29, T24 and FL3 exosomes on human umbilical vein endothelial cell (HUVEC) monolayer integrity was determined by transendothelial electrical resistance (TEER) measurements and transport was determined by flow cytometry. Complement activation studies in human serum of malignant and non‐malignant cell‐derived exosomes were performed.

Results

FL3, T24 and HCV‐29 cells produced exosomes at similar concentration per cell (6.64, 6.61 and 6.46×104 exosomes per cell for FL3, T24 and HCV‐29 cells, respectively) and of similar size (120.2 nm for FL3, 127.6 nm for T24 and 117.9 nm for HCV‐29, respectively). T24 and FL3 cell‐derived exosomes exhibited a markedly reduced stiffness, 95 MPa and 280 MPa, respectively, compared with 1,527 MPa with non‐malignant HCV‐29 cell‐derived exosomes determined by QNM AFM. FL3 and T24 exosomes induced endothelial disruption as measured by a decrease in TEER in HUVEC monolayers, whereas no effect was observed for HCV‐29 derived exosomes. FL3 and T24 exosomes traffic more readily (11.6 and 21.4% of applied exosomes, respectively) across HUVEC monolayers than HCV‐29 derived exosomes (7.2% of applied exosomes). Malignant cell‐derived exosomes activated complement through calcium‐sensitive pathways in a concentration‐dependent manner.

Conclusions

Malignant (metastatic and non‐metastatic) cell line exosomes display a markedly reduced stiffness and adhesion but an increased complement activation compared to non‐malignant cell line exosomes, which may explain the observed increased endothelial monolayer disruption and transendothelial transport of these vesicles.
Direct estimate of the internal π-donation to the carbene centre within N-heterocyclic carbenes and related molecules
Authors: Andrada Diego M , Holzmann Nicole , Hamadi Thomas , Frenking Gernot
Published: December 2015

Fifteen cyclic and acylic carbenes have been calculated with density functional theory at the BP86/def2-TZVPP level. The strength of the internal X→p(π) π-donation of heteroatoms and carbon which are bonded to the C(II) atom is estimated with the help of NBO calculations and with an energy decomposition analysis. The investigated molecules include N-heterocyclic carbenes (NHCs), the cyclic alkyl(amino)carbene (cAAC), mesoionic carbenes and ylide-stabilized carbenes. The bonding analysis suggests that the carbene centre in cAAC and in diamidocarbene have the weakest X→p(π) π-donation while mesoionic carbenes possess the strongest π-donation.
FAMILY CHARACTERISTICS AND GOVERNANCE OF SMALL AND MEDIUM-SIZED FAMILY FIRMS
Authors: Felício J. Augusto , Villardón Maria Purificación Galindo
Published: December 2015

The purpose of this paper is to study the influence of family characteristics on the governance of small and medium-sized family firms. The study presents and tests a theoretical model resorting to data on 151 Portuguese SMEs. The study uses nonlinear principal component analysis by alternating least squares, bivariate analysis and cluster analysis. Family characteristics influence governance mechanisms and family firms form clusters based on family characteristics and governance mechanisms. The results reveal that family characteristics are a source of heterogeneity among family firms which corroborates the criticism on family firms' homogeneity assumption. The identification of clusters of firms constitutes a reference for family firms' definition of governance models. The originality of the paper relies on the analysis of specific family characteristics and its importance as a source of family firms' heterogeneity is proven. This study opens new insights on family firms' governance research and may be extended to other family characteristics and overall implications on performance.
ROLE OF E-BUSINESS IN THE PERCEPTION OF ICT IMPACT ON REVENUE GROWTH
Authors: Delina Radoslav , Tkáč Michal
Published: December 2015

Perceived gain from the use of e-business information and communication technologies (ICT) represents the main driver that motivates companies to implement them. The study focuses on the perception of e-business ICT applications within companies. On the sample of 11,072 companies from 27 EU states, we have determined which of e-business ICT application the companies use and how they perceive the impact of ICT on their revenue growth. An ordinal regression and decision tree analysis have been used to identify a portfolio of e-business ICT applications. We have also proposed three hypotheses to test whether the perceived impact of ICT is influenced by the number of implemented e-business ICT applications, or by the number of procurement-orientated e- business ICT applications, or even by the number of sales-orientated ones. The research not only helps practitioners to recognize which tools are behind the positive perception regarding the impact of ICT on revenue growth, but it tries to answer the question of whether the quantity of implemented applications really improves the acknowledged influence of ICT on revenue growth.
ASYMMETRIC DOUPOLY COMPETITION WITH INNOVATION SPILLOVER AND INPUT CONSTRAINTS
Authors: Chen You-hua , Nie Pu-yan , Wang X. Henry
Published: December 2015

This paper subjects to examine how technology spillover affects input competition and how input constraints impact firm innovation by a two-stage game model and theoretic analysis. The results show that with low spillover, the high cost firm can capture more input than the low cost firm through cost-reducing innovation. Adding input increases firms’ innovation, but it cannot improve the disadvantaged firm's state under input constraint. Compared with non-cooperative innovation, cooperative innovation reduces innovation difference and firm size difference. The research implications are that disadvantage firms could take innovation spillover and capacity constraints as a competition strategy to obtain competition advantage and regulators should stimulate cooperative innovation to higher social welfare. The major value of this paper is that it combines capacity constraints and innovation investment originality.
La grammaire est-elle une compétence ?
Authors: Bulea Bronckart Ecaterina
Published: December 2015

L'article questionne la possibilité de considérer la grammaire comme une compétence. Dans une première partie, centrée sur la notion de compétence, l'auteure procède à un bref rappel de l'histoire de cette notion mettant en évidence sa labilité, puis présente les deux principales conceptions de la compétence aujourd'hui en vigueur, pour inscrire la discussion du statut de la grammaire dans une conception processuelle dynamique. Dans la seconde partie de l'article, centrée sur le statut de la grammaire, elle engage cette discussion en exploitant les définitions de la notion de « langue » issues de l'œuvre de F. de Saussure, ainsi que certains développements actuels de la didactique du français. La contribution montre ainsi que la grammaire n'est pas une compétence, cette dernière se situant au niveau de la maitrise et de la pratique des textes ; textes qui constituent en revanche la base de construction de ressources grammaticales (ré)exploitables.
Des compétences en littérature pour « comprendre le présent » ?
Authors: Quet François
Published: December 2015

La littérature à l'école semble pouvoir se passer assez bien de la notion de compétence. Est-ce parce que les « tâches complexes » sont déjà familières dans l'enseignement du français ? Est-ce parce que les finalités de la littérature ne sont pas si précises qu'on puisse efficacement les évaluer ? Est-ce parce que la critique du technicisme et du positivisme en usage dans les années 1970-80 a fini par empêcher toute possibilité d'objectiver les attentes d'une formation à la lecture littéraire ? L'article reprend les thèses développées dans un débat (Citton, Croce-Spinelli, Dumortier, Jorro, Louichon, Quet, Sorin) initié sur le site de l'INRP (désormais IFÉ). Loin d'être incompatible avec la notion de sujet lecteur, devenue incontournable en didactique de la littérature, le travail par compétences permettrait d'accorder des contenus plus didactiques à cette notion (qui reste très théorique), en particulier en explicitant avec les élèves les finalités de notre enseignement (comprendre notre présent par la lecture de textes littéraires) et les connaissances nécessaires à la transformation progressive de jeunes lecteurs, en progression permanente.
La logique des compétences dans l'histoire de la lecture scolaire
Authors: Chartier Anne-Marie
Published: December 2015

Comme le « savoir lire » a toujours été considéré comme une compétence (une habileté, un savoir-faire, selon l'époque), le passage d'une logique scolaire centrée sur les disciplines à une approche par compétences n'aurait pas dû l'affecter. Tout au contraire, considérer la lecture comme une compétence transversale a rendu sa définition plus complexe et plus floue : le savoir lire est tantôt réduit à la décodification, tantôt élargi à la compréhension de tous les types de textes. De fait, le « savoir lire » visé scolairement n'est pas indépendant des pratiques sociales de lecture qui ont profondément changé au fil du temps comme le montre l'histoire. De ce fait, la formation des maitres chargés de cet apprentissage a dû être redéfinie en conséquence. Ce sont ces trois questions (les interférences entre connaissances et compétences, l'évolution de la notion de « savoir lire » et l'évolution des objectifs de la formation des maitres) que cette contribution tente d'éclairer.
Évaluer la justice
Authors: Cantegreil Julien
Published: December 2015

On ne peut pas améliorer la qualité de l’institution judiciaire si l’on omet de réfléchir à sa fonction au sein de la société. Utilisant les moyens de la philosophie et de l’anthropologie politique, nous montrerons que cette fonction renvoie in fine à une certaine définition de l’activité politique. Nous présenterons ensuite les différentes conceptions fondamentales que l’on peut repérer au cours de l’histoire. Nous montrerons enfin, dans le cadre d’une pensée moderne de l’activité politique, trois manières contradictoires de définir la fonction de l’institution judiciaire et les difficultés actuelles qu’elles génèrent. Il s’agira non de trancher le débat mais de le poser avec le maximum de clarté.
Changement stratégique, cognition managériale et diversité des membres de l’équipe dirigeante
Authors: Ben Lahouel Béchir , Autissier David , Montargot Nathalie
Published: December 2015

La théorie des échelons supérieurs éclaire d’un jour nouveau le lien possible entre les caractéristiques démographiques des membres de l’équipe dirigeante et le changement stratégique matérialisé par une rupture avec l’inertie organisationnelle. En vertu du principe que les orientations stratégiques des organisations sont le reflet des valeurs et des bases cognitives des acteurs influents en leur sein, la théorie des échelons supérieurs offre une nouvelle grille de lecture. Cette recherche vise à cerner les contours et les implications de la théorie des échelons supérieurs dans la compréhension de la diversité des cognitions managériales et de leurs implications dans les choix stratégiques. Elle consiste également à proposer un modèle conceptuel articulé autour de propositions de recherche, appréhendant les facteurs démographiques pouvant expliquer le changement de stratégie.
Pour une prise en compte des clivages au sein des classes populaires
Authors: Peugny Camille
Published: December 2015

Cet article met en évidence l’hétérogénéité du rapport à la politique des classes populaires. Grâce aux données de l’enquête Participation électorale 2012 de l’Insee et aux quatre premières vagues de l’European Social Survey, deux dimensions de la participation politique des employés et des ouvriers sont questionnées : la participation électorale lors des scrutins présidentiel et législatif de 2012, ainsi qu’une dimension plus subjective, renvoyant à la capacité de se saisir des questions politiques. Des variations importantes sont mises en évidence entre les différentes catégories d’employés et d’ouvriers qui ne peuvent pas uniquement être imputées à l’effet des variables socio-démographiques habituelles. La position très détériorée des employés des services à la personne conduit à insister sur l’importance des collectifs de travail dans la structuration du rapport au politique.
La quadrature du conte. La féerie en France au temps du romantisme (1800-1848)
Authors: Chelebourg Christian
Published: December 2015

La France a connu avant ses voisins, dès Perrault, le mouvement de retour à ses sources populaires et fabuleuses. Mais, au début du xix e siècle, l’attitude de Mme de Staël témoigne d’une évolution durable à l’égard du merveilleux : le besoin de vérités hérité des Lumières empêche désormais toute hypotypose de l’irréel. D’accord avec Walter Scott qui redoute une mise à nu des artifices de l’écriture, Nodier prône un merveilleux rationalisé : ce sera le fantastique. Le succès des « Féeries » dramatiques sur les scènes populaires contribue au discrédit de leur imaginaire. Dans ces conditions, il ne peut se renouveler que dans la littérature de jeunesse, avec Mme de Girardin ou Hetzel, avant Dumas qui entame, en 1844, son entreprise de phagocytage des œuvres d’Hoffmann, Grimm et Andersen.
« La question de la technique » de Martin Heidegger
Authors: Maffesoli Michel
Published: December 2015

L’importance de La question de la technique de Heidegger réside dans l’affirmation que la technique n’est pas seulement une activité de l’homme, ni un pur et simple outil d’une telle activité. Elle n’est pas seulement un instrument mais une manière de dévoilement qui en représente son essence ; une essence qui s’assimile au destin de l’être. La relecture et l’interprétation de cette « question » nous indique une rupture avec une conception paranoïaque du monde et un retour de la puissance destinale que l’on retrouve dans les racines de notre présent.
Le sujet de la technique : maîtrise, aliénation, expérimentation
Authors: Benoist Jocelyn
Published: December 2015

Nous questionnons la figure philosophique traditionnelle de la technique moderne come un processus métaphysique résultant de la domination d’un idéal de Sujet faisant de tout dans le monde (y compris sa même concrète subjectivité) son « objet ». Il cherche à donner un cadre plus complexe de ce que les modernes appellent « technique », en soulignant d’un côté sa continuité avec les arts traditionnels, et de l’autre côté les nouvelles concrètes possibilités qui émergent de son actuel départ de leur model. Ainsi, il détecte dans la « technique » moderne un nouveau système de la subjectivité, au-delà à la fois du contrôle et de l’aliénation. La technique nous ouvre des nouvelles dimensions de l’expérience et brise des nouveaux chemins pour la subjectivité.
Management of Sport-Related Concussion in the Pediatric and Adolescent Population
Authors: Provance Aaron J. , Engelman Glenn H. , Terhune E. Bailey , Coel Rachel A.
Published: December 2015

Concussions make up nearly 10% of all high school athletic injuries. Recent changes in concussion management guidelines and legislation aim to make concussion care more standardized and safe but simultaneously pose a challenge for the primary care and sports medicine physician. Pediatric and adolescent concussions may cause anxiety for the treating physician due to concerns over return-to-play decisions, academic issues, and the potential for second impact syndrome. Determining when to refer a patient to an emergency department acutely, to an outpatient concussion clinic, or to other subspecialists may be a difficult decision for the primary care physician. The aim of this article is to review current evidence regarding concussion treatment and return-to-school and return-to-play recommendations to provide the primary care and sports medicine physician with practical guidelines for managing concussions.

Sobre la autoría de Indispositione generale della monarchia di Spagna
Authors: Boadas Sònia
Published: December 2015

Indispositione generale della monarchia di Spagna es un breve tratado político escrito en italiano a finales de 1630 que seguramente habría pasado inadvertido si a mediados del siglo XX no se hubiera atribuido a la pluma del escritor y diplomático Diego de Saavedra Fajardo. Este trabajo pretende revisar exhaustivamente los argumentos que se utilizaron para validar esta tesis así como exponer una serie de nuevos documentos y algunas consideraciones que apuntan a la escasa posibilidad de que el texto saliera de la pluma del literato español.
Juan Rejano en México: Los criterios del crítico literario
Authors: Olmedo Muñoz Iliana
Published: December 2015

Este trabajo analiza la columna que Juan Rejano mantuvo durante décadas en el diario El Nacional como ejemplo de la crítica literaria que los exiliados españoles realizaron en México, un capítulo importante y poco estudiado del diálogo cultural entre intelectuales exiliados y mexicanos. Aunque el registro de la columna es muy amplio, examinar la labor de Rejano como crítico de narrativa mexicana revela sus filiaciones, su idea de tradición y de calidad literaria. Además descubre, desde el caso concreto de Rejano, cómo los exiliados participaron e influyeron en la conformación del medio cultural mexicano.

Les méthodes analytiques de la biogéochimie s’appliquent depuis plusieurs dizaines d’années aux études archéologiques. L’une des questions majeures posées par cette approche reste la conservation des signaux biogéochimiques pendant la phase taphonomique. Nous proposons ici un exemple qui a fait l’objet d’une présentation poster au 7ème Congrès sur la diagénèse des ossements de Lyon (7th International Bone Diagenesis Meeting Lyon, France, October 22nd-25th 2013).Les informations concernant les habitudes alimentaires sont enregistrées dans les os du squelette durant la vie des individus. Mais elles peuvent être ensuite perturbées par des modifications minéralogiques intervenant après l’inhumation. Cependant, certaines conditions favorisent la conservation des tissus squelettiques qui sont préservés de cette altération post-mortem. C’est en particulier le cas des ossements déposés depuis quelques siècles (xie-xviiie) dans les grottes funéraires des falaises de Bandiagara (Mali) par les Tellem, puis par les Dogon. Ils sont macroscopiquement semblables aux os frais. Leur extraordinaire état de préservation aux plans minéralogique, géochimique et organique est démontré par les études par diffraction des rayons X, la mesure de leur teneur en matière organique, l’observation histologique sur lame mince, leur composition chimique élémentaire (Mg, Na, F, Mn, Fe, Y, La, Ce, U) et le rapport calcium versus phosphore.Comme en Afrique de l’Ouest, les éléments concernant l’approche de l’alimentation passée sont rares, ces squelettes humains offrent l’opportunité de tester la qualité des données géochimiques sur la paléodiète dans les domaines du δ13C, δ18O, Sr/Ca, Ba/Ca pour l’apatite osseuse, et du δ13C and δ15N pour le collagène. Les résultats sont discutés en fonction d’approches ethnologiques réalisées en Mali rural.
Health Diagnosis by Single Smartphone
Authors: Spaanenburg Lambert
Published: December 2015

M-Health promises to bring the ease and robustness of the thermometer to general health. Casual handling implies non-invasive measurements, where of old the hand is the main instrument to diagnose health. A smartphone or a wearable can ‘extend' the hand by embedding diagnosing intelligence. The paper discusses the role of neural modeling & matching to create such intelligence for the determination of general health factors. It is illustrated in blood pressure measurement of 90-95% medical accuracy without additional accessories.
Modeling of Linguistic Reference Schemes
Authors: Halpin Terry
Published: December 2015

When using natural language, people typically refer to individual things by using proper names or definite descriptions. Data modeling languages differ considerably in their support for such linguistic reference schemes. Understanding these differences is important for modeling reference schemes within such languages and for transforming models from one language to another. This article provides a comparative review of reference scheme modeling within the Unified Modeling Language (version 2.5), the Barker dialect of Entity Relationship modeling, Object-Role Modeling (version 2), relational database modeling, and the Web Ontology Language (version 2.0). The author identifies which kinds of reference schemes can be captured within these languages as well as those reference schemes that cannot be. The author's analysis covers simple reference schemes, compound reference schemes, disjunctive reference and context-dependent reference schemes.
Ontology Learning from Text
Authors: Browarnik Abel , Maimon Oded
Published: December 2015

The goal of Ontology Learning from Text is to learn ontologies that represent domains or applications that change often. Manually learning and updating such ontologies is too expensive. This is the reason for the Ontology Learning discipline's emergence. The leading approach to Ontology Learning from Text is the Ontology Learning Layer Cake. This approach splits the task into four or five sequential tasks. Each of the tasks may use diverse methods, ranging from uses of Linguistic knowledge to Machine Learning. The authors review the shortcomings of the Ontology Learning Layer Cake approach and conclude that the approach is not viable for Ontology Learning from Text. They suggest alternative approaches that may help learning ontologies in an efficient, effective way.
Analysis of the High Buildings Structure
Authors: Miedziałkowski Czesław , Matulewicz Sandra , Mackiewicz Monika
Published: December 2015

An analysis of the high building construction has been presented in the paper. Recently high buildings are getting more popular and more common in urban building industry. Moreover nowadays the main trend of the erected constructions is energy saving. Therefore there is necessity to connect these two features. Very helpful for that purpose can be a modern glazing building elevation, which can be used as a solar collectors. For the analysis five different types of high building structures have been taken. As the first analyzed model, core – frame construction with the columns placed on the edge of the building has been considered. In this case the area of glazing surface has been significantly reduced. That is why in a second model, it was decided to move back the columns from the edge, 1.0 meter inside the building. However, for this type of construction, according to obtained results, horizontal displacement of the top of building was greater than allowed by specified standards. In order to fulfill standard requirements and keep a sufficiently large area of glazing, in the third analyzed model extra beams were inserted on the height of 2.5m. In the fourth model added a little truss.
Neural Approximation of the Buckling Coefficient of Compression Flange of Box Girder Evenly Loaded Transversely
Authors: Potrzeszcz-Sut Beata , Szychowski Andrzej
Published: December 2015

There are situations in the thin-walled steel girders with box intersection, in which the internal wall of compression flange is elastically restrained in the webs of section and along its length occurs the change of normal stresses. Such a wall was modelled, as a bilateral elastically restrained internal plate variably loaded at the length. Explicit formulation of neural formula on buckling coefficient of internal plate at non-linear distribution of longitudinal stress was discussed in this paper. A few structures of neural networks (NN) were envisaged in order to obtain the best of the numerical effectiveness of the final formula. The results noted from the literature were used for the evaluation of neural prediction of coefficient.
Adhesion Assessment between Concrete Layers Using the Ultrasonic Pulse Velocity Method
Authors: Szymanowski Jacek , Sadowski Łukasz
Published: December 2015

Adhesion assessment between concrete layers with the use of the non-destructive ultrasonic pulse velocity (UPV) method has been described in the article. Two-layer concrete elements, obtained by drilling the core from a large size multilayer element, were the object of testing. The ultrasonic wave velocity of the element and the materials of which its layers were made were assigned for each element. On that basis, the comparative velocity i.e. the velocity at which an ultrasonic wave going through the boundary surface of layers wouldn’t cause any change in the velocity, was determined. The ratio of the two velocities has been compared to adhesion values obtained through the semi-destructive pull-off method. It was revealed that when the ratio of the ultrasonic wave velocity of the element to comparative velocity increases, the pull-off adhesion value also increases.
The Effect of Adding Selected Nanoparticles on the Mechanical Properties of the Cement Matrix of Self-Compacting Concrete
Authors: Niewiadomski Paweł , Stefaniuk Damian
Published: December 2015

The interest in nanomaterials as an addition that improves the properties of concrete has been growing for more than a decade. One of the principal ways of evaluating concretes is the testing of their micro- and nanohardness by means of nanoindentation. This paper presents the results of nanoindentation tests of hardened self-compacting concrete modified with different amounts of nanoparticles. The investigations covered a reference series of self-compacting concrete without any nanoparticle addition and ten concrete series modified with different amounts of SiO2, TiO2and Al2O3powder nanoparticles. An analysis of the test results is carried out and conclusions are drawn.
Application of FEM Mesh Generation Algorithm for Digital Processing of Handmade Sketches
Authors: Gryniewicz Marcin , Szlendak Jerzy K.
Published: December 2015

Handmade sketches of different shapes roof structures, often with openings, are outlined on plain sheet of paper. Then, they are transformed by a 2D mesh generation and applied to FEM calculations. Algorithm where only main coordinates of nodes are used as user input data is studied by the Authors. Shape of the surface, its curvature and openings are detected through the procedures developed in the C++ programming language. A particular emphasis is put to the automation of the process. At a present version the method is used for rectangular shapes, which are quite common in civil engineering structures e.g. building elevations. Detection and processing algorithms are implemented with a usage of a library based on a open code called OpenCV. The computer software is described in this paper and some examples are given
Experimental Data Acquisition System for Flow Boiling in Mini Channels
Authors: Grabowski Mirosław , Poniewski Mieczysław , Alabrudziński Sławomir , Płaczkowski Krzysztof
Published: December 2015

The study discusses experiments on ethanol flow boiling in mini-channels. Pre-set thermal and flow parameters (pressure and temperature at the inlet, mass flux, the heat flux delivered to the heater) and temperature, pressure and void fraction measurements obtained in the experiment provided data for further simulation computations. On the basis of high-speed camera images, void fraction in the mini-channel was determined. Thermograms of the heater surface and the surface in the adiabatic part of the mini-channel allowed producing temperature profiles along the channel length. The read and computed parameters satisfy the expected dependences (especially that for void fraction as a function of volume flux and heat flux). Those were used to solve inverse heat conduction problems.

There were performed computations for the analysis of the hydrodynamic pressures and liquid energy dissipation for different kinds of liquid cargo transported in the road tanks with perforated and solid baffles. Also different filling levels of the reservoir were considered. The configuration of the internal lateral baffle providing maximal efficiency of liquid oscillations damping and minimal loading of the road tank shell was suggested.

Published: December 2015

Computer simulation of contact interaction between a spherical indenter and soil surface was performed by the means of ANSYS software. It was assumed that the soil was elastically-plastically deformed in accordance with the model of Drucker-Prager. The case of indenter inserting and its contemporaneous displacement along the contact surface was considered. The results obtained by different material models show that the maximal stresses are reduced by 50% and more for the Drucker-Prager model in comparison with the results for the elastic model. The influence of horizontal movement-vertical movement ratio for the indenter on the stresses in the soil was analyzed.

The Influence of Stretch Rod Speed on the Relationship between Preblown Bottle Aesthetic Quality and Final Blown Bottle Thickness Profile in Stretch Blow Molding from Preform Process
Authors: Wawrzyniak Paweł
Published: December 2015

From a mechanical point of view, the aesthetic quality of preblown PET bottles and thickness profile of final blown PET bottles manufactured in ISBM process are determined by mechanical and thermal response of blown preforms. From the microscopic point of view the biggest influence on the mechanical and thermal properties of PET bottles have orientation and crystallization processes. From a technological point of view, the aesthetic quality and thickness profile is mainly determined by the preforms initial structure of the PET material, preforms thermal profile heating, stretch rod speed, preblowing air pressure, and the so-called delay. More specifically, the properties of PET bottles affects as many as 14 variables, however, in this paper they are not individually discussed. In the paper it will be described the influence of stretch rod speed on relationship between preblown bottle aesthetic quality and final blown bottle thickness profile in SBM from preform process.
Research on the Phenomenon of Relaxation of Compressed Concrete Elements
Authors: Kamiński Krzysztof , Ciarkowski Bartłomiej
Published: December 2015

This article presents results of research aimed at identifying the phenomenon of stress relaxation in compressed concrete elements. The study used a special test stand, designed and constructed by Dr.Eng. Krzysztof Kaminski which allows permanent strain of cylindrical concrete sample by adjusting force. Cylindrical samples with a diameter of 15 cm and 10.5 cm and a height of 30 cm for the study were used. The samples were made of different classes of concrete. There was also defined the influence of applied tensile stress and the age of the sample on the relaxation phenomenon. The expected result of the research was to obtain relaxation curves of concrete samples with different compressive strength and age. Relaxation of concrete is important for the analysis of bending elements sections, which behavior during the operational phase of the concrete can significantly deviate from the assumed one, causing other than triangular or parabolic distribution of compressive stresses.

Authors: Lechniak Juliusz , Kamiński Krzysztof
Published: December 2015

The most comfortable way to present capacity is M-N interaction curve diagram (bending moment and longitudinal force). Graph of M-N most commonly appears as a function, where an axial force is the argument and the bending moment is the value. This work introduce a formation of the curve way, where the the rotation angle of the strain diagram is the argument, and the full strain diagram is the value. Using the complete state of the strain of the cross section, enables easy calculation the M-N forces using stress-strain diagram for a given material. Interaction graph is based on parabola-rectangle diagram for concrete and the graph with inclined top branch with strain limit for reinforcing steel. The method has no restrictions due to the concrete class.
ASSESSMENT OF THE CAPABILITY OF 3D STRATIFIED FLOW FINITE ELEMENT MODEL IN CHARACTERIZING MEANDER DYNAMICS

Published: December 2015

There have been attempts to simulate meander dynamics (Langbein and Leopold 1966, Oodgard 1989, Campoerale et. al 2007, da Silva and El-Tahawy 2008, Duan and Julien 2010, Blanckaert and de Vriend 2010, Esfahani and Keshavarzi 2011). Meandering geometry is complex phenomena (Chanson 2004, Wu 2008), this would include the dynamics of flow properties and of morphology. Simulating meander flow dynamics is mostly popular using either Finite Element Method (FEM) or Finite Volume Method (FVM) where are based on Eulerian description, and based on stationer grid-based methods (Wormleaton and Ewunetu 2006, Wu 2008, Duan and Julien 2010, Gomez-Gesteira et. al 2010). As such this model is lack of capability in simulating the dynamics of meander morphology; much effort is put through to overcome this issue with such as Smoothed Particle Hydrodynamics (SPH), Boundary Element Methods, Arbitrary Lagrangian Eulerian, etc. This paper has two objectives; to identify meander flow characteristics and sediment transport distribution patterns, and to simulate meander flow characteristics and sediment transport distribution patterns using FEM. This study has identified that the key of dynamics of flow characteristics are helical flow and coherent structures, and the key of dynamics of transport characteristics are erosion-deposition zone patterns. The finite element model using in this study, RMA has shown its capability to simulate the meander key characteristics above, for small deflection angles (30°) location of maximum erosion-deposition zones near the crossover of the sinuosity, for intermediate deflection angles (70°) location of maximum erosion-deposition zones between the crossover and apex of the sinuosity, and for large deflection angles (110°) location of maximum erosion-deposition zones near the apex of the sinuosity, these are agreed with experiments of Odgaard 1989, da Silva 2006, da Silva et. al 2006, and Esfahani and Keshavarzi (2012). These results can be used as a reference to develop a method to model meander morpho-dynamics.

Authors: Mah Jon , Kass Rosman
Published: December 2015

Context: Decompressive craniectomy is commonly use as the treatment for medically refractory intracranial hypertension. Unexpected improvement in patient's neurological status has been observed among patients that underwent cranioplasty. Restoration of cerebral blood flow (CBF) hemodynamics is one of the contributing factors. This study was conducted to determine the impact of cranioplasty on CBF and its correlation with clinical outcome. Aims: This study was done to evaluate the effect of cranioplasty on CBF with computed tomography perfusion (CTP). It also aimed to determine the correlation between postcranioplasty CBF and clinical outcome. Settings and Design: Prospective observational study. Subjects and Methods: All patients had CTP done to determine precranioplasty CBF. CTP was repeated at 6 weeks postcranioplasty and clinical assessment at 6 and 24 weeks postcranioplasty. Statistical Analysis Used: Data analysis was done using Statistical Package for Social Sciences version 12.0.1. Results: The median value of the ipsilateral CBF was 48.87 and 61.10 ml/min/100 g at precranioplasty and 6 weeks postcranioplasty (P < 0.001). Contralateral CBF also showed improvement from 60.55 to 71.84 ml/min/100 g (P < 0.001). Median value for mini mental state examination showed a significant difference with value of 22, 25, and 25.5 at precranioplasty, 6 and 24 weeks postcranioplasty (P = 0.001 and P < 0.001). Median value for frontal assessment battery was 12, 14.5, and 15 (P = 0.002 and P = 0.001). Conclusions: Cranioplasty can remarkably improve cortical perfusion for both ipsilateral and contralateral hemisphere. Though we are unable to establish strong correlation, between CBF and clinical outcome, cranioplasty was observed to have a therapeutic role in terms of clinical outcome improvement.
