El sistema educativo en la provincia de León
Authors: Fernández Santos Yolanda
Published: May 2016

La evolución del sistema educativo español ha estado condicionada por la existencia de numerosas normas, especialmente en la enseñanza no universitaria, conllevando, en ocasiones, a la no aplicación completa de las nuevas fórmulas educativas aprobadas. El objetivo de este trabajo consiste en analizar la evolución del sistema educativo en la provincia de León tanto de las enseñanzas universitarias como no universitarias en el periodo comprendido entre 1986 y 2010. Para ello, se hace una comparación de la situación educativa de la provincia de León con las existentes en la Comunidad Autónoma de Castilla y León, y en España.

The evolution of the Spanish educational system has been conditioned by the existence of numerous standards, especially those related to non-university education. This fact has sometimes led to an incomplete implementation of the new educational approved methods. The aim of this study is to analyse the evolution of the educational system in the province of Leon from 1986 to 2010, at both university and non-university levels. With this purpose we make a comparison between the educational situation in the province of Leon and this situation in Castile and Leon Region and Spain.

Authors: Nagoti Sarada , J. Anunayi , Patel Manthan
Published: May 2016

Background: The disease biology of Follicular neoplasms of thyroid with hurthle cells is poorly understood.  Very few studies in literature have addressed the role of p53 in these neoplasms. The aim of the present study is to analyze the histomorphological features of Follicular neoplasms with hurthle cell change and to evaluate the role of p53 in their tumor biology.

Methods:32 cases of Follicular neoplasms of thyroid with focal and pure hurthle cell change over a period of 2.5 years were studied histologically and immunohistochemically using p53 antibody (Biogenex). They included 20 follicular adenomas with focal hurthle cells, 10 pure hurthle cell adenomas and 2 hurthle cell carcinomas.

Results: All cases showed nuclear p53 positivity in hurthle cells. Muller-Hocker et al criteria was used for frequency scoring. Out of the 32 cases, 12 cases of pure hurthle cells showed score 3, Remaining 20 cases of follicular adenomas with focal hurthle cell change showed score 3 in cases with >50% hurthle cells, score 2 in cases with 20-40% hurthle cells and score 0 in cases with <10% hurthle cells.

Conclusions:The study showed a good correlation of p53 protein expression with tumor progression and aggressiveness. Hence this indicates that molecular alterations in p53 pathway play a role in tumor biology in Follicular neoplasms of thyroid with hurthle cell change.
A comparison of genetic variations among native andsome local chicken populations in Turkey
Authors: Tunca Rahsan Ivgin , Taskin Atilla
Published: May 2016

Genetic variations among native and local chicken populations in six different locations across Turkey were established using 15 ISSR primers, and produced 87 bright and reproducible bands. According to pairwise genetic differentiation among the populations (GST), the highest genetic differentiation was determined between the Samsun and Yozgat population and the lowest was observed between the Dulkadirli and Budak populations. Shannon’s index was calculated to be 0.239. The gene flow (Nm) among the populations was estimated to be 3.489, which indicated low levels of differentiation among the populations. Analysis of Molecular Variance (AMOVA) identified 13% of the total genetic variation between the populations and the rest of the differences were 87% within the populations. Cluster analysis revealed two main branches, one leading to the domestic chicken population collected from Samsun in the Black Sea region of Turkey, the other branch clustered into two branches; one branch consisting of the Denizli Native Chicken population and the other one of domestic chicken populations sampled from Central Anatolia populations. The study is important to clarify the indigenous chicken genetic resources in Turkey. The results could be used for future breeding research conducted by either the public or private sectors.

Published: May 2016

This study examined the effect of reused treated grey water on yield of 10 pearl millet accessions (Pennisetum glaucum) in An-Najah University, Tulkarm, Palestine. Ten pearl millet seeds were planted during May 2010 in each separate plastic containers (35 x 50 x 15 cm) filled with 45 kg sandy clay soil in four replication of a completely randomized design and irrigated with three types of water (Fresh water as control, raw grey water, treated grey water). Results clearly showed that there were no significant differences in the yield under different water treatments. Also no significant interaction was observed between water treatments and cultivars. However, accessions IP3616, IP22269, Sudan pop II, and Sudan pop I gave high total fresh weight fresh weight of straw while accessions IP3616 and IP22269 produced the highest fresh weight of straw. The accessions IP6104, IP6110, IP19612 and ICMV155 registered the highest plant height.
Review of The Interpersonal Communication Book, 13th edition by Joseph A. Devito, New York: Pearson, 2012, 432 pages
Authors: Schiau Ioana
Published: May 2016

Despite numerous handbooks, encyclopaedias and essential volumes on the topic which became available on the market throughout the years, one book stands apart, and has now reached its 13th edition and continues to inspire and inform young academics in universities worldwide. Joseph A. Devito’s “The Interpersonal Communication Book” is a well-structured and fundamental book on interpersonal communication, which covers topics as broad as relationships, conflict and communication ethics, and proves the key point that interpersonal communication is many-faceted, depending on dimensions such as individual apprehension, assertiveness or adequacy.

Hormone D and its analogues display immunomodulatory activities providing a beneficial effect in immunoinflammatory diseases. The aim of this study was to assess the effect of alfacalcidol treatment on superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPx) activity and glutathione (GSH) and malondialdehyde (MDA) levels in patients with active RA. Sixteen patients with active RA and twenty controls were enrolled in the study. Blood samples were taken before and after 12 weeks of alfacalcidol therapy (2 ?g/day). Oxidative stress parameters were determined spectrophotometrically and by flow cytometry assessment. Disease activity was assessed using DAS28 score. The results revealed that alfacalcidol treatment, significantly (p = 0.04) reduced SOD activity and CAT activity (p = 0.001) in RA patients. The activity of GPx was significantly lower in RA patients before treatment, compared to controls (p = 0.04). After therapy, GPx activity was restored to control levels, and GSH levels were significantly reduced (p = 0.01). MDA levels in patients at the beginning of the study protocol, remained significantly elevated compared to controls (p = 0.01). Alfacalcidol treatment decreased MDA levels in patients (p = 0.19). Furthermore, 12-weeks alfacalcidol therapy, changed the response of RA patients? PBMC to stimulation preventing the O2 - production and mitochondrial membrane depolarisation. After alfacalcidol treatment, significant clinical improvement was observed.

Authors: Spink John , Fortin Neal D. , Moyer Douglas C. , Miao Hong , Wu Yongning
Published: May 2016

This paper addresses the role of governments, industry, academics, and non-governmental organizations in Food Fraud prevention. Before providing strategic concepts for governments and authorities, definitions of Food Fraud are reviewed and discussed. Next there is a review of Food Fraud
activities by the Global Food Safety Initiative (GFSI), the Elliott Review in the United Kingdom, the European Commission resolution on Food Fraud, and the US Food Safety Modernization Act including the Preventative Controls Rule. Two key concepts for governments or a company are: (1) formally,
and specifically, mention food fraud as a food issue and (2) create an enterprise-wide Food Fraud prevention plan. The research includes a case study of the implementation of the concepts by a state or provincial agency. This analysis provides a foundation to review the role of science and
technology in detection, deterrence and then contributing to prevention.
Chemical Analysis: An Indispensable Means for Uncovering Severe Cases of Fraud with Cosmetics and Tattoo Inks
Authors: Hohl Christopher , Hauri Urs
Published: May 2016

Three cases of fraud with commodities containing illegal stealth compounds are presented, which were uncovered by the State Laboratory Basel-City, Switzerland. All three commodities, grapefruit seed extracts, a phytocosmetical skin cream, and tattoo inks, were produced abroad, had forged
declarations of ingredients and, in the case of the extracts and the cream, were marketed with far-reaching health claims. While inspections will identify suspicious products and would be able to eliminate health claims to some extent, only chemical analysis can uncover the illegal agents
used and give law enforcement bodies the necessary evidence to immediately clamp down on those brands, where the stealth agent presents a serious health hazard to consumers.
REMOVAL OF AMMONIUM IONS FROM DIGESTED SLUDGE FUGATE BY USING NATURAL ZEOLITE
Authors: MAŽEIKIENĖ Aušra , VALENTUKEVIčIENĖ Marina
Published: May 2016

Wastewater treatment loadings with total nitrogen can increased by introducing fugate that is saturated with ammonium ions, generated when dewatering wastewater treatment sludge. In this article the possibility to reduce the concentration of ammonium ions in the fugate by the use of natural zeolite (Transcarpatian clinoptilolite) has been analysed. Lab-scale experiments were carried out with different particle sizes zeolite: 0.8–1.6 mm, 1.6–2.5 mm and 2.5–3.2 mm. At the first stage of the experiments, zeolite particles were mixed with fugate and left to settle until a 99% efficiency of ammonium ion removal was achieved. At the second stage, ammonium ions were removed from the fugate by filtering this liquid through zeolite where the 70–92% efficiency was achieved. Zeolite saturated with ammonium ions possibly can be used in agriculture as nitrogenous fertilizers. Obtained fertilizer grade of zeolite saturated with fugate can also be produced from the high ammonium nitrogen concentration side-streams separated from wastewater flow from sludge digestion processes.
Excellence et égalité
Authors: Mosconi Nicole
Published: May 2016

Les politiques scolaires occidentales croient pouvoir concilier égalité et excellence, par l’égalité des chances. En France, dans un système scolaire unifié et mixte, on a prétendu, au nom de « l’excellence pour tous », instruire la totalité d’une classe d’âge avec les programmes convenant à une minorité privilégiée. Dès lors, l’école est devenue une machine à sélectionner les élèves, en fonction de déterminants qui ont reproduit les hiérarchies sociale, sexuée et ethnique. Des courants politiques en conflit opposent une classe dominante, conservatrice, qui entend maintenir ses positions privilégiées au nom de l’excellence, à des mouvements syndicaux et féministes. Les premiers s’opposent à la transmission d’une culture commune au collège et aussi à l’éducation à l’égalité des sexes, quand les seconds défendent ces deux principes au nom d’une conception démocratique d’égal accès de toutes et de tous à tous les savoirs.
Post-scriptum de l’article « La banalité du mâle : Louis Althusser a tué sa conjointe, Hélène Rytmann-Legotien, qui voulait le quitter »
Authors: Dupuis-Déri Francis
Published: May 2016

Ce post-scriptum d’un article paru dans NQF en 2015 permet de réagir à la publication du livre de Louis Althusser, Des rêves d’angoisse sans fin , qui propose une série de notes sur les rêves de l’assassin, accompagnée de quelques pages exposant l’interprétation du meurtre que son analyste lui aurait suggérée. Ce livre est paru après la sortie de l’article dans NQF , qui cherchait à saisir la signification politique du meurtre d’Hélène Rytmann-Legotien par son conjoint, Althusser, et du discours psychologisant diffusé dans l’espace public pour déresponsabiliser, voire justifier le meurtrier. Ce post-scriptum est l’occasion de reprendre cette réflexion à la lumière du nouveau livre d’Althusser, qui relève de la même logique.
Évaluation de l’effet d’une politique spatialisée d’accès au logement
Authors: Gobillon Laurent , Vignolles Benjamin
Published: May 2016

La Loi relative à la solidarité et au renouvellement urbains, dite loi sru , votée en décembre 2000, impose aux communes moyennes et grandes de disposer d’au moins 20 % de logements sociaux sous peine d’amende. Nous en évaluons les effets pour les communes dont la population est voisine du seuil d’application de la loi. Les estimations sont menées en différences de différences. La loi sru aurait eu un effet positif significatif sur la construction de logements sociaux, croissant au cours du temps. Dans les communes de notre échantillon ayant initialement un parc de logements sociaux, la loi aurait augmenté le taux de croissance annuel du nombre de logements sociaux de 1,25 point en moyenne durant la période 2000-2008. L’effet se serait concentré sur les communes initialement les plus éloignées de l’objectif de la loi, dont la proportion de logements sociaux est inférieure à 5 % en 2000. Nous trouvons aussi que la loi aurait entraîné une baisse de la ségrégation intracommunale des logements selon le type (social ou privé), peut-être à cause d’un développement plus éparpillé des logements sociaux. Nous ne mettons pas en évidence d’effet de la loi sur les prix de l’immobilier dans l’ancien.
De possibles « correspondances » entre neurosciences et psychanalyse au sujet de la mémoire
Authors: Infurchia Claudia
Published: May 2016

L’œuvre freudienne ne comporte pas de théorisation générale sur la mémoire alors que la question des traces mnésiques à formes variées y est prépondérante. La mémoire figure au rang des objets d’études des neurosciences, les différences de position épistémologique entre psychanalyse et neurosciences apparaissent comme une difficulté majeure pour un travail commun. Cependant, le complémentarisme de G. Devereux, par la méthodologie des correspon-dances entre deux disciplines, ouvre cette perspective, en évitant l’écueil de l’amalgame. L’émotion apparaît comme un point d’articulation entre ces deux champs hétérogènes pour penser la question de la mémoire.
Retour sur la construction des relations militaires franco-africaines
Authors: Evrard Camille
Published: May 2016

Cet article présente le processus d’adaptation des institutions militaires coloniales au nouveau cadre qu’est la Communauté franco-africaine de 1958. Il montre l’échec successif des projets d’armée unique et de défense commune qui présidaient à ce projet, devenu caduque en moins de deux ans. En ancrant cette histoire dans des exemples locaux et en scrutant les multiples contraintes, politiques, inter-personnelles et institutionnelles, on relativise l’idée d’un transfert militaire « qui irait de soi » au moment de la décolonisation de l’Afrique subsaharienne. Ces difficultés, qui concernent la construction des nouvelles armées nationales par les gouvernements africains ainsi que la place de l’assistance technique militaire française entre 1959 et la fin des années 1960, n’empêchent pour autant pas l’établissement d’un outil d’influence française efficace. Motivé par une volonté politique forte, cet outil s’appuie sur l’expérience des cadres militaires de l’assistance technique, même s’il s’incarne avant tout dans les interventions militaires des premières décennies postcoloniales
Les technocrates et les « relations spéciales » franco-américaines, 1969-1973
Authors: Bourliaguet Bruno
Published: May 2016

La compréhension de l’assistance secrète offerte par les États-Unis à la France pour le développement de son armement nucléaire durant les années 1970 impose de dissocier les niveaux politique et exécutif. Au niveau exécutif, la nature technocratique de cette assistance se révèle extrêmement bénéfique pour les Français. Une mise en contexte historique de cette technocratie et une relecture des archives disponibles concernant l’assistance permettent de démontrer l’influence positive de certains technocrates américains, en particulier celle de John Foster Jr., à l’époque numéro trois du département de la Défense, que cela concerne les relations avec les Français ou la synergie avec le Conseil de sécurité nationale.
The three wives problem and Shapley value
Authors: de Mesnard Louis
Published: May 2016

Nous examinons un des problèmes talmudiques historiques, les trois épouses, une généralisation du problème talmudique du vêtement contesté, résolu par Aumann et Maschler (1985) en utilisant la procédure coalitionnelle. Ce problème a de nombreuses applications pratiques. Dans sa tentative pour unifier toutes les méthodes talmudiques, Guiasu (2010, 2011) dit qu’il peut être expliqué en termes de “ruée vers la banque”, c.-à.-d. de valeur de Shapley dans un “jeu cumulatif”. Cette approche doit être reconsidérée parce que la procédure coalitionnelle donne le même résultat que le nucléolus qui correspond à un “jeu dual”. Comme la solution de Guiasu est paradoxale (elle a toutes les apparences de la vérité), ma contribution est d’expliquer les concepts, principalement la troncation qui joue un rôle central dans la démonstration, puis d’analyser en quoi l’argument de Guiasu est trompeur. Après avoir rappelé ce qu’est le problème du partage selon le Talmud, comment il est résolu par la procédure coalitionnelle d’Aumann et Maschler (c.-à.-d. le nucléolus ou la valeur de Shapley du jeu dual) et comment Guiasu la résout par la valeur de Shapley d’un jeu cumulatif, on montre que: 1) Guiasu a omis de tronquer de données (les demandes qui dépassent la richesse doivent être réduites au niveau de la richesse disponible) alors que c’est nécessaire ici. 2) Il attribue l’excédent (obtenu après le partage de la richesse) à tous les candidats de manière égale: cela contredit la solution du vêtement contesté. 3) Ceci implique que la richesse ne peut pas dépasser la plus grande demande, ce qui est évidemment faux. 4) L’approche de Guiasu crée une discontinuité dans la distribution de la richesse, qui n’est pas observée dans le problème du vêtement contesté. On conclut que la tentative de Guiasu de réunifier les méthodes de partage selon le Talmud par la valeur de Shapley est n’est pas couronnée de succès et est en fait contradictoire avec le vêtement contesté.
Three Wives Problem and Shapley Value. Answer to Professor De Mesnard’s Criticism
Authors: Guiasu Silviu
Published: May 2016

Les solutions des vieux problèmes de la banqueroute, de l’arbitrage des droits et de la dispute sur le vêtement ont été données dans le Talmud sans aucune justification. Un article publié dans la revue Synthese (Guiasu 2011) a montré que ces solutions peuvent être obtenues en utilisant la valeur de Shapley de la théorie des jeux avec n partenaires si les fonctions caractéristiques des jeux qui correspondent aux trois problèmes mentionnés dépendent essentiellement du contexte respectif. Trois ans plus tard, une critique de l’article publié en Synthese a été publiée sur l’internet (De Mesnard 2014). On trouvera ici la réponse à cette critique.
Nuclear magnetic resonance analysis of freeze-thaw damage in natural pumice concrete
Authors: Wang Xiaoxiao , Shen Xiangdong , Wang Hailong , Gao Chu , Zhang Tong
Published: May 2016

This paper presents an analysis of the damage propagation features of the pore structure of natural pumice lightweight aggregate concrete (LWC) under freeze-thaw cyclic action. After freeze-thaw cycling, we conducted nuclear magnetic resonance (NMR) tests on the concrete and acquired the porosity, distribution of transverse relaxation time T2, and magnetic resonance imaging (MRI) results. The results showed the following. The T2 distribution of the LWC prior to freeze-thaw cycling presented four peaks representative of a preponderance of small pores. After 50, 100, 150, and 200 freeze-thaw cycles, the total area of the T2 spectrum and the porosity increased significantly. The MRI presented the changing spatial distribution of pores within the LWC during freeze-thaw cycling. Ultrasonic testing technology was applied simultaneously to analyze the NMR results, which verified that the new NMR technology demonstrated high accuracy and practicability for research regarding freeze-thaw concrete damage.
Orientación cultural hacia la innovación en empresas. Un enfoque sociológico del Sistema de Innovación de Galicia
Authors: Fernández-Jardón Fernández Carlos M. , González-Loureiro Miguel , Pita-Castelo José
Published: May 2016

Las características sociológicas de las organizaciones influyen en los resultados del proceso de innovación. Por tanto, es necesario conocer cuáles de esas características describen mejor a las empresas con mayores resultados de innovación, entre las que se encuentra la cultura de innovación existente en un contexto dado. Este estudio analiza dichos elementos sociológicos en una muestra de 441 empresas del Sistema Regional de Innovación de Galicia. Mediante métodos multivariantes se detectaron dos perfiles empresariales de orientación cultural hacia la innovación: un 47 % con una clara orientación hacia la innovación y un 53 % con una orientación menor. Los resultados evidenciaron la existencia de una asociación positiva entre la orientación cultural hacia la innovación y el desempeño innovador. Nuestra evidencia señala que la cultura de innovación es una dualidad capacidad-actitud, potencialidad-acción. Esto abre nuevas perspectivas de investigación a la sociología de la innovación en los sistemas regionales de innovación.
Faire voyager des danses et des idées : la formation d’un espace chorégraphique européen par les « danses gravées » au xviiie siècle
Authors: Glon Marie
Published: May 2016

La Chorégraphie ou l’art de décrire la dance, publiée à Paris en 1700, présente un art scripturaire permettant d’établir des « danses gravées » (l’équivalent, pour la danse, de partitions musicales). L’étude des documents relatifs à la Chorégraphie révèle les circulations dont ces danses gravées ont fait l’objet au xviiie siècle : pour les maîtres de danse qui y recourent, la Chorégraphie devient une sorte de langue écrite internationale, participant à la formation d’un réseau chorégraphique européen, au sein duquel circulent danses, écrits et innovations techniques.
Mobilités et précarités : Lorenzo Da Ponte dans le monde de l’opéra (1779-1830)
Authors: Do Paço David
Published: May 2016

Cet article interroge le rapport entre mobilités géographiques et mobilités sociales au sein du milieu de l’opéra du xviiie siècle et autour de la carrière erratique de Lorenzo Da Ponte. Il souligne le rôle du patronage dans l’attraction et la circulation des auteurs et des compositeurs ainsi que l’existence de solidarités corporatistes plus ou moins institutionnalisées qui permettent de réguler un marché de la musique et des arts lyriques. Néanmoins, auteurs, compositeurs et acteurs proposent des mobilités à contretemps et des logiques de carrière différentes malgré une nécessaire complémentarité si ce n’est une certaine interdépendance. La précarité des conditions et des emplois suscite encore une recherche de sécurité qui passe parfois par un changement de statut social et professionnel. Toute mobilité n’est donc pas circulation et ni obligatoirement vertueuse, au contraire, la mobilité est souvent le signe d’une précarité économique et sociale.
Reliability of Existing Concrete Bridges from the Aspect of the Reinforcement Corrosion
Authors: Kotes Peter , Vican Josef , Brodňan Miroslav , Nikolić Ružica R.
Published: May 2016

The quality and durability of the concrete structures are affected by many degradation processes. The reliability of existing bridge structures is significantly affected by numerous factors, from which the reinforcement and structural steel corrosion, together with effect of traffic action, are the most important. Corrosion is the destructive attack on metal by chemical or electrochemical reaction with its environment. In the case of reinforced concrete (RC) structures, the most known degradation process is corrosion of reinforcement. RC members have to fulfill the conditions given in Eurocode [1, 2]. Horizontal beams are mainly subjected to bending and shear. The paper deals with reinforcement corrosion of main longitudinal reinforcements (reinforcement against bending) and its influence on the moment resistance of the existing bridge concrete structures. The two types of active stage calculation of corrosion were considered in this paper. The length of passive stage was not known, so it was calculated backwards.
Influence of the Different Factors on Formation of Cracks on the Foundation Slabs, Concrete Pavements and Industrial Floors at an Early Stage - Parametric Study
Authors: Ignacak Miroslav , Šoltész Július
Published: May 2016

Many factors play important role during concreting the base slabs, industrial floors and concrete pavements. Often, there is a tendency to design the structure so that the crack does not arise or arise only with the limited crack width. The parametric study of selected climatic factors which have crucial affect on the temperature or cracking development of the structure at an early stage is elaborated in the paper.The results were obtained using thermodynamic and stress numerical model TD&SM, which was developed in the last four years at the Department of Concrete Structures and Bridges. The outputs from program TD&SM were tested and compared with experimental measurements on real structures, and showed very good agreement. It is possible to calculate the temperature development at any time and place of base slab, industrial floor or concrete pavement at the early stage using this model . It enables afterwards to investigate the risk of crack creation.

Physical and Chemical State of the Concrete Piers of the Former Franz Joseph Bridge Built in 1891
Authors: Janotka Ivan , Paulík Peter , Ševčík Patrik , Bačuvčík Michal
Published: May 2016

This article discusses the properties of concrete within the piers of the Old Bridge in Bratislava (former Franz Joseph Bridge). It was the first permanent bridge across the river Danube in Bratislava as well as within the present territory of Slovakia. Mechanical, physical and chemical properties were verified on core drills, some of them being almost 23 m long. The concretes were tested for dynamic and Young’s elasticity module and compressive strengths. Subsequently the fines of concrete specimens were studied by the X-ray diffraction, TG-DTA and mercury intrusion porosimetry techniques and also by chemical analyses and SEM observations. The piers were made from 5 different concrete kinds. The concrete in the caissons and in the piers does not fulfil the criteria for structural concrete defined in the present European standards. This finding seriously suggests that carrying capacity of the piers after the reconstruction of the bridge, without any strengthening would become questionable.
The Crack Development Mechanism of Prestressed Girder Influenced by Different Bond between Prestressed Tendons and Concrete
Authors: Borzovič Viktor , Laco Ján , Pecník Miroslav , Pažma Peter
Published: May 2016

The paper deals with formation and development of cracks up to the failure of two span post-tensioned concrete girder. It is focused on influence of different bond between prestressing units and surrounding grout. Monitored and analysed phenomena affected by different bond are as follows: crack initiation, crack spacing and crack width of the prestressed girder. Sources of analysis are results from experimental program focused on influence of oil based corrosion protection agents on bond of prestressing units. Two span post-tensioned girders were subjected to the loading in laboratory till the bending failure has occurred. Girders were in two cases prestressed with bonded tendons. Other two girders were post-tensioned with unbonded tendons and two girders with tendons with decreased bond, due to corrosion protection coatings. Girders have demonstrated different behaviour by loading regarding to the bond level of prestressing units. Experimental results are faced with the results of the theoretical calculation of crack width according to European standards.
Numerical Modeling of the Subsoil-Structure Interaction
Authors: Vaskova Jana , Čajka Radim
Published: May 2016

Numerical interaction model of reinforced concrete slab and subsoil was created in ANSYS. Input data for numerical analysis were obtained during experimental loading test of reinforced concrete slab. Loading test was performed using unique experimental equipment constructed in the area of Faculty of Civil Engineering, VŠB-TU Ostrava. Analysis of interaction of reinforced concrete slab with subsoil was solved with application of inhomogeneous half-space. Application of inhomogeneous half-space allows better capture the subsoil behaviour and its increasing modulus of deformability with increasing depth of subsoil model. Homogeneous half-space this takes no account. Reinforced concrete slab was cracked during an experiment. The effect of cracks was also taken into account in the numerical model of reinforced concrete slab using derived modulus of elasticity of cracked concrete. Values calculated by all types of interaction models were compared with values measured during the loading test of reinforced concrete slab.
Design of Concrete Slabs Reinforcement – Methods of FEM Results Interpretation Incorporating Twisting Moments
Authors: Bartók Andrej
Published: May 2016

There are many analytical methods to solve internal forces of slabs. But structural engineers work with structural analysis software, based mainly of finite element method (FEM). Interpretation of that analysis results may lead to errors during concrete slab reinforcement design. There are some methods to solve the problem. Most familiar are Wood-Armer equations, introduced in 1968. But other methods exists furthermore. It is common, that design engineer doesn’t know, which method his program uses. This article deals with common – not only Wood-Armer - methods of concrete slab reinforcement design incorporating twisting moments, design of skew angle reinforcement etc. Description of selected software approach.

Research, emphasizing to experimental work, is conducted on a 1.5 KVA single-phase transformer to measure the internal temperature of the primary and secondary winding, using reliable instruments. Special consideration is given to the convenience in the acquisition and management of experimental data, so that the proposed monitoring system can be exploited for all kinds of thermal tests and various loading conditions. The transformer under study is designed and constructed from scratch, according to particular technical specifications. Having completed the transformer construction with the temperature sensors linked in each coil, our aim is to apply various types of loads and record the temperature variation inside the transformer. A process of acquisition and processing of data related to various parameters of transformers is developed so as to predict the behavior and prevent the failure of a transformer.

An actual problem is the synthesis of ceramic composite materials based on refractory compounds to produce nanostructured materials with high mechanical strength, namely, flexural strength, fracture toughness, hardness, heat resistance and thermal strength. Of particular interest is the transformational-reinforced ceramic, which is not inferior in strength characteristics of conventional structural alloys. Particularly noteworthy are composites based on the composition ZrO2 / Al2O3, which have high strength and toughness in comparison with monozirconium or monocorundum ceramics.

Regulatory T cells (Tregs) induced during autoimmunity often become quiescent and unable to resolve disease, suggesting inadequate activation. Resolution of established experimental autoimmune encephalomyelitis (EAE) can be achieved with myelin oligodendrocyte glycoprotein (MOG) fused to reovirus protein σ1 (MOG-pσ1), which activates Tregs, restoring protection, but requiring other regulatory cells to revitalize them. B cells have a dichotomous role in both the pathogenesis and recovery from EAE. Although inflammatory B cells contribute to EAE’s pathogenesis, treatment of EAE mice with MOG-pσ1, but not OVA-pσ1, resulted in an influx of IL-10–producing B220+CD5+ B regulatory cells (Bregs) enabling Tregs to recover their inhibitory activity, and in turn, leading to the rapid amelioration of EAE. These findings implicate direct interactions between Bregs and Tregs to facilitate this recovery. Adoptive transfer of B220+CD5− B cells from MOG-pσ1–treated EAE or Bregs from PBS-treated EAE mice did not resolve disease, whereas the adoptive transfer of MOG-pσ1–induced B220+CD5+ Bregs greatly ameliorated EAE. MOG-pσ1–, but not OVA-pσ1–induced IL-10–producing Bregs, expressed elevated levels of B and T lymphocyte attenuator (BTLA) relative to CD5− B cells, as opposed to Tregs or effector T (Teff) cells, whose BTLA expression was not affected. These induced Bregs restored EAE Treg function in a BTLA-dependent manner. BTLA−/− mice showed more pronounced EAE with fewer Tregs, but upon adoptive transfer of MOG-pσ1–induced BTLA+ Bregs, BTLA−/− mice were protected against EAE. Hence, this evidence shows the importance of BTLA in activating Tregs to facilitate recovery from EAE.
Teaching natural science in the foundation phase: Teachers’ understanding of the natural science curriculum
Authors: James Angela
Published: May 2016

This study explores foundation phase teachers’ understanding of the natural science curriculum within the life skills learning programme. The theoretical framework for this study is entrenched in the relationship between the intended and the implemented curriculum. The Zone of Feasible Innovation (ZFI) is the proposed theory of implementation and states that implementation of the intended curriculum is very difficult if teachers do not have the capacity to implement it. The study seeks to determine where teachers are operating within their ZFI. Data was collected through questionnaires, interviews as well as a rating scale for teachers. The findings show that teachers are confident to teach content that they have been teaching for a long time, but are reluctant to introduce new science topics or new methods of instruction. This reluctance impacts on their ability to implement new innovations in science teaching. However, there are signs that their ZFI has progressed to include certain new practices.
Transition process of abrupt climate change based on global sea surface temperature over the past century
Authors: Yan Pengcheng , Hou Wei , Feng Guolin
Published: May 2016

Abstract. A new detection method has been proposed to study the transition process of abrupt climate change. With this method, the climate system transiting from one stable state to another can be verified clearly. By applying this method to the global sea surface temperature over the past century, several climate changes and their processes are detected, including the start state (moment), persist time, and end state (moment). According to the spatial distribution, the locations of climate changes mainly have occurred in the Indian Ocean and western Pacific before the middle twentieth century, in the 1970s in the equatorial middle-eastern Pacific, and in the middle and southern Pacific since the end of the twentieth century. In addition, the quantitative relationship between the transition process parameters is verified in theory and practice: (1) the relationship between the rate and stability parameters is linear, and (2) the relationship between the rate and change amplitude parameters is quadratic.

Published: May 2016

Sin duda, los productores saben de la influencia lunar y sobre el movimiento de la savia en las plantas en determinados momentos, debido a los conocimientos ancestrales y experiencias adquiridas. Sin embargo, en relación al prendimiento de injertos en cacao (Theobroma cacao), existen pocos estudios científicos que demuestren tales efectos. El objetivo principal del estudio fue comparar los efectos de las fases lunares en el prendimiento de dos tipos de injertos en cacao. Para ello se utilizó un diseño completamente al azar con arreglo bifactorial, con tres repeticiones por cada una de las fases y un universo de 576 plantas. La variable de medición únicamente fue el prendimiento de las plantas que se injertaron.Los datos fueron procesados en el programa Statistical Product and Service Solutions (SPSS) versión 21 y se sometieron al análisis de varianza ANDEVA con un nivel de confianza del 95%. Los análisis revelan que existen diferencias significativas para las técnicas de injertación (p=0.011<0.05) y se obtuvo mayores prendimientos en los injertos de yema sobre los de bisel. Con respecto al efecto de las fases lunares sobre los dos tipos de injertos no se encontró evidencia estadística (p=0.950>0.05). En base al análisis combinado de varianza no existen diferencias significativas para la interacción fases lunares y técnicas de injertación puesto que (p=0.761>0.05).

Understanding Judges’ Choices of Sentence Types as Interpretative Work: An Explorative Study in a Dutch Police Court

This article critically evaluates the prevailing factor-oriented (e.g. a priori defined legal and extralegal characteristics of defendants) approach in analyses of judicial decision-making. Rather than assuming such factors, we aim to demonstrate how Dutch judges engage in interpretative work to arrive at various sentence types. In their interpretative work, judges attempt to weigh and compare various legal and extralegal features of defendants. Importantly, they do so in the context of the case as a whole, which means that these features do not have independent or fixed meanings. Judges select and weigh information to create an image of defendants’ redeemability. However, extralegal concerns other than redeemability also inform judges’ decisions. We argue that studying the naturally occurring interpretative work of judges results in a better understanding of judicial decision-making than outcome-oriented studies, which view criminal cases as collections of independent legal and extralegal factors.
