Published: June 2016

We present the results of the most complete scan of the parameter space for cosmic ray (CR) injection and propagation. We perform a Bayesian search of the main GALPROP parameters, using the MultiNest nested sampling algorithm, augmented by the BAMBI neural network machine-learning package. This is the first study to separate out low-mass isotopes (p,

, and He) from the usual light elements (Be, B, C, N, and O). We find that the propagation parameters that best-fit

, and He data are significantly different from those that fit light elements, including the B/C and 10Be/9Be secondary-to-primary ratios normally used to calibrate propagation parameters. This suggests that each set of species is probing a very different interstellar medium, and that the standard approach of calibrating propagation parameters using B/C can lead to incorrect results. We present posterior distributions and best-fit parameters for propagation of both sets of nuclei, as well as for the injection abundances of elements from H to Si. The input GALDEF files with these new parameters will be included in an upcoming public GALPROP update.
CHEMICAL ABUNDANCES IN NGC 5024 (M53): A MOSTLY FIRST GENERATION GLOBULAR CLUSTER
Authors: Boberg Owen M. , Friel Eileen D. , Vesperini Enrico
Published: June 2016

We present the Fe, Ca, Ti, Ni, Ba, Na, and O abundances for a sample of 53 red giant branch stars in the globular cluster (GC) NGC 5024 (M53). The abundances were measured from high signal-to-noise medium resolution spectra collected with the Hydra multi-object spectrograph on the Wisconsin–Indiana–Yale–NOAO 3.5 m telescope. M53 is of interest because previous studies based on the morphology of the cluster’s horizontal branch suggested that it might be composed primarily of first generation (FG) stars and differ from the majority of other GCs with multiple populations, which have been found to be dominated by the second generation (SG) stars. Our sample has an average [Fe/H] = −2.07 with a standard deviation of 0.07 dex. This value is consistent with previously published results. The alpha-element abundances in our sample are also consistent with the trends seen in Milky Way halo stars at similar metallicities, with enhanced [Ca/Fe] and [Ti/Fe] relative to solar. We find that the Na–O anti-correlation in M53 is not as extended as other GCs with similar masses and metallicities. The ratio of SG to the total number of stars in our sample is approximately 0.27 and the SG generation is more centrally concentrated. These findings further support that M53 might be a mostly FG cluster and could give further insight into how GCs formed the light element abundance patterns we observe in them today.
OPTICAL ABSORPTIONS OF OXYGENATED CARBON CHAIN CATIONS IN THE GAS PHASE
Authors: Hardy F.-X. , Rice C. A. , Chakraborty A. , Fulara J. , Maier J. P.
Published: June 2016

The gas-phase electronic spectra of linear OC4O+ and a planar C6H2O+ isomer were obtained at a rotational temperature of ≈10 K. Absorption measurements in a 6 K neon matrix were followed by gas-phase observations in a cryogenic radiofrequency ion trap. The origin bands of the

transition of OC4O+ and the

A

B1 of HCCC(CO)CCH+ lie at 417.31 ± 0.01 nm and 523.49 ± 0.01 nm, respectively. These constitute the first electronic spectra of oxygenated carbon chain cations studied under conditions that are relevant to the diffuse interstellar bands (DIBs), as both have a visible transition. The recent analysis of the 579.5 nm DIB indicates that small carriers, five to seven heavy atoms, continue to be possible candidates (Huang & Oka 2015). Astronomical implications are discussed regarding this kind of oxygenated molecules.
Aptidão funcional de mulheres de meia-idade e idosas ingressantes em um programa de atividades físicas em unidades de saúde
Authors: De Oliveira Vinicius Machado , Brasil Marcos Roberto , Cavazzotto Timothy Gustavo , Ferreira Sandra Aires , Queiroga Marcos Roberto
Published: June 2016

OBJETIVO: Comparar a aptidão funcional entre mulheres de meia-idade e idosas ingressantes em um programa de atividades físicas.

MÉTODOS: Participaram do estudo 64 mulheres, divididas em dois grupos, sendo Grupo da Meia-Idade (G1: 46,8±9,0 anos) e Grupo Idoso (G2: 66,3±4,3 anos). Os componentes da aptidão funcional foram verificados através da bateria de testes da American Alliance for Health, Physical Education, Recreation and Dance (AAHPERD), depois analisados estatisticamente e por normatizações propostas na literatura.

RESULTADOS: Os resultados demonstraram diferenças significativas em três parâmetros da aptidão funcional, a resistência aeróbia (G1: 525,3±64,3seg; G2: 577,4±91,1seg; p<0,01*), a agilidade (G1: 28,1seg±5,4seg; G2: 31,6±6,1seg; p<0,01*) e a coordenação (G1: 16,8seg±8,4seg; G2: 21,5seg±10,7seg; p<0,01*), os quais se apresentaram melhores no grupo da meia-idade. Entretanto, quando comparados por meio de valores normativos, ambos os grupos foram classificados com aptidão funcional como fraca.

CONCLUSÕES: Os dados presentes neste estudo revelam que o comprometimento da aptidão funcional pode ocorrer mais cedo, principalmente em função da insuficiência da atividade física, que pode acelerar o processo de envelhecimento. Os resultados indicam que ambos os grupos são insuficientemente ativos fisicamente.

 
La « ligne brisée » : ontologie relationnelle, réalisme social et imagination morale
Authors: Kaufmann Laurence
Published: June 2016

Dans une première étape, cet article présente les principales déclinaisons descriptives d’une ontologie qui place la relation « au commencement » du sujet et de la société. Sous cet angle descriptif, la normativité ne se présente jamais de façon désincarnée ; elle est encapsulée dans des activités pratiques et des relations d’échange qui entremêlent orientations morales et affiliations sociales. Dans une deuxième étape, cet article vise à montrer que, du point de vue normatif, le réalisme social ordinaire qui mêle ainsi savoir-faire social et devoir-faire moral doit être suspendu. Les critères restreints et sélectifs des appartenances et des positionnements sociaux doivent être mis de côté pour qu’une véritable posture morale, ainsi que l’acte d’imagination qui lui est corrélatif, puissent s’épanouir.
Qu’y a-t-il de relationnel dans le social ? Vincent Descombes et les leçons du don
Authors: Callegaro Francesco
Published: June 2016

Cet article entend développer une thèse fort répandue en sociologie et en anthropologie : le social est constitué de relations. Prenant appui sur les travaux philosophiques de Vincent Descombes, il élabore progressivement une série de distinctions conceptuelles permettant de préciser ce qu’il y a de spécifiquement relationnel dans le social : relations externes et internes, mentales et réelles, dyadiques et triadiques, causales et normatives, symétriques et asymétriques. Revenant à l’ Essai sur le don de Marcel Mauss, saisi dans son irréductibilité à la lecture influente proposée par Claude Lévi-Strauss, cet article vise surtout à expliquer ses principales leçons philosophiques. Dans les pratiques de don, il s’agit d’honorer l’exigence de justice qui est au fondement de toutes les relations sociales.

La relation, l’incertitude et la contestation politique. Limites de l’anthropologie d’Arnold Gehlen pour la sociologie des institutions
Authors: Renou Gildas
Published: June 2016

Cet article présente et discute la théorie de l’institution développée par le sociologue allemand Arnold Gehlen (1904-1976). Cette théorie, peu connue en France mais influente dans les sciences sociales contemporaines, repose sur l’hypothèse selon laquelle les institutions sociales découlent de la nature biologiquement imparfaite de l’espèce humaine. L’article explore les implications scientifiques et politiques de cette hypothèse, en particulier l’impossibilité de penser l’apprentissage personnel et le dissensus politique. En s’appuyant sur des apports récents, l’article propose enfin d’esquisser une perspective relationnelle et dynamique des institutions en développant une approche de l’incertitude dans la vie sociale opposée à celle de Gehlen.
De la relation à l’existence : sciences sociales ou sciences humaines
Authors: Piette Albert
Published: June 2016

La réflexion de cet article part du contexte intellectuel des dernières années privilégiant nettement une pensée relationniste et propose de distinguer la science sociale de la science humaine et, plus spécifiquement, la sociologie (y compris les anthropologies sociales et culturelles) de l’anthropologie au sens strict du terme, comme science des hommes. L’article, d’une part, propose une critique de différentes lectures relationnistes (Goffman, Lévi-Strauss, Bourdieu, Latour) ainsi que de l’ethnographie comme relationnisme méthodologique et, d’autre part, à l’aide des notions de volume d’être et d’exo-actions, il veut valoriser l’idée de séparation et de singularité des individus ainsi que la méthode phénoménographique pour apprendre à regarder et analyser des êtres séparément.
Une relation effacée
Authors: Lamarche Jean-Baptiste
Published: June 2016

La cure psychanalytique se présente comme une pratique qui soustrait le patient au regard intériorisé des autres et lui permet de reconnaître dans ce rapport à soi purifié une volonté primitive et asociale, précédemment refoulée sous leur pression. En localisant cette théorie de la volonté primitive dans le contexte des relations où elle fut créée et utilisée, nous pouvons voir au contraire que le portrait du rapport à soi qu’elle offre ne cesse jamais d’être dépendant du monde des interactions médiatisées par les symboles. En effet, ce portrait permet d’ordonner des interactions en les situant par rapport aux significations communes caractéristiques des sociétés démocratiques contemporaines.
La complexité évangélique du don
Authors: Laupies Vincent
Published: June 2016

Le don selon l’Évangile est souvent perçu comme un don absolutisé, sans réciprocité, sans limites, jusqu’au don de soi. Cependant, si l’on prend l’ensemble des enseignements évangéliques sur le don, il apparaît que l’Évangile promeut au contraire une conception très réaliste du don. L’expérience montre que la conception absolutisée du don contribue largement à diverses perversions.
Au début était la relation ? Convenientia et aptum chez Augustin d’Hippone
Authors: Marianelli Massimiliano
Published: June 2016

Relation est d’une certaine manière ce qui qualifie chaque possible « être ici » de l’homme et ce thème de la relation est le thème central de la réflexion philosophique dès ses débuts. Dans la philosophie chrétienne, est central le problème de considérer le rapport à un début, un Dieu, qui est Créateur et se place dans une relation active avec l’homme. Le renvoi à Augustin est central car il réélabore en quelque sorte le concept même de « relation » en proposant un profond remaniement à la lumière de la Révélation Chrétienne, en en retraçant immédiatement le principe de l’Âme qui, qualifiée comme Imago Dei , est le centre d’une ontologie relationnelle. Dans cet article, nous revenons sur la notion de convenientia pour réfléchir à nouveau sur une façon précise de penser la relation, qui a subi de profonds changements dans l’histoire de la pensée.
Billy Budd. L’innocence et le mystère d’iniquité
Authors: Terestchenko Michel
Published: June 2016

Le roman Billy Budd, laissé par Herman Melville inachevé au moment de sa mort en 1891, se présente comme la chronique d’un épisode tragique survenu dans la marine britannique à la fin du xviii e siècle. Mais sous l’anecdote se lit la confrontation cosmique entre le Bien et le Mal, incarnés par les deux personnages clés, le Beau Matelot et le capitaine d’armes. Toutefois, Melville en vint progressivement à accorder une place centrale au commandant du navire, véritable figure du prince bon machiavélien, contraint de prendre une décision déchirante au mépris de ses sentiments. Le roman peut être interprété autant comme le testament littéraire de Melville sur la question du mal, sans que l’on puisse trancher entre des conclusions opposées, que comme l’expression de son profond scepticisme sur les conceptions humaines du bien et du juste.
Modalités décisionnelles des athlètes d’élite relatives à leur intégration en pôle d’entraînement
Authors: Ledon Aurélie , Debois Nadine , Rosnet Élisabeth
Published: June 2016

Dans la majorité des sports, les athlètes de haut niveau se retrouvent fréquemment en situation de devoir prendre des décisions qui mettent en jeu leur parcours. L’une d’elles concerne le choix d’intégrer ou non un pôle d’entraînement (Espoir ou France). Cette entrée constitue une transition forte aux multiples implications auxquelles l’athlète devra s’adapter. La question est alors de savoir quels sont les éléments susceptibles d’influer sur la décision de l’athlète. L’étude menée repose sur un modèle prenant en compte quatre facteurs susceptibles de peser sur la décision ( i.e. , modèle Push Pull Anti-push Anti-pull ; Schultz, Morton, &Wercherle, 1998) : (1) des éléments d’attraction ( i.e. , les intérêts qu’offre la situation nouvelle), (2) des éléments d’incitation ( i.e. , éléments du contexte actuel qui poussent à aller vers autre chose), (3) des éléments d’attachement ( i.e. , ce que l’on va perdre dans le changement) et (4) des éléments dissuasifs ( i.e. , les coûts et les risques que l’on appréhende dans la situation nouvelle). Un total de 31 entretiens semi-directifs ont été conduits. Nous nous sommes pour cela focalisées sur l’entrée dans la pratique sportive et les processus favorables ou défavorables ayant une influence sur le choix d’intégrer un pôle. Ainsi, nous avons pu constater que les principaux facteurs interagissaient dans le processus décisionnel.

Published: June 2016

Cette étude compare les différences concernant les caractéristiques psychosociales et les attitudes alimentaires entre des jeunes patineurs artistiques français et canadiens. Un total de 221 patineurs artistiques d’élite, 101 Canadiens et 120 Français, ont participé à l’étude. Les attitudes alimentaires désordonnées et six variables psychosociales incluant la qualité de l’amitié en sport, la qualité de la relation avec l’entraîneur, la qualité de la relation avec les parents, l’acceptation sociale des pairs perçue, l’habileté physique et l’apparence physique perçues ont été mesurées à l’aide de questionnaires. Les patineurs canadiens ont montré une qualité de relation sociale avec l’ami en sport, les parents et l’entraîneur plus élevée, une perception de l’habileté et de l’apparence physique plus élevée et un plus haut niveau de désordres alimentaires comparativement aux participants français ; cependant, les Français ont reporté des scores d’acceptation sociale des pairs plus élevés. Dans les deux groupes, une relation positive et significative a été observée entre : la qualité de la relation avec l’entraîneur et la qualité de la relation avec l’ami en sport, la qualité de la relation avec les parents et l’habilité ou l’apparence physique perçue, l’acceptation sociale des pairs et l’habilité physique perçue. L’habilité physique perçue était négativement reliée aux attitudes alimentaires désordonnées dans le groupe canadien mais positivement associée dans le groupe français. En conclusion, un cercle vicieux entre la relation entraîneur-athlète, l’habileté physique perçue et les désordres alimentaires a été observé auprès des patineurs d’élite français comparés aux patineurs canadiens suggérant des différences culturelles entre les deux pays.

Published: June 2016

De nombreuses recherches se sont intéressées aux variables liées à l’adhésion des personnes vieillissantes envers l’activité physique. L’objectif de cette étude était de recenser les différents programmes de promotion de l’activité physique chez les personnes âgées de 65 ans et plus, afin de savoir si, et de quelle façon, les barrières affectives associées à l’idée de pratiquer une activité physique avaient été considérées dans la construction de ce type d’interventions. Les critères d’inclusion/exclusion ont permis de retenir huit des 1 195 citations soulignant principalement l’influence interpersonnelle comme variable incontournable de la réussite des programmes de promotion de l’activité physique, et suggérant une considération partielle de la dimension affective dans la lutte contre la sédentarité. Ensemble, ces résultats mettent en avant les intérêts scientifiques et appliqués d’une élaboration théorique de programmes de promotion basés sur la régulation émotionnelle interpersonnelle des personnes âgées.
Activité physique et vieillissement cognitif : effets modulateurs du gène du facteur neurotrophique dérivé du cerveau
Authors: Canivet Anne , Audiffren Michel
Published: June 2016

Le vieillissement s’accompagne généralement d’une altération fonctionnelle et structurale de notre système nerveux central. Parmi les stratégies de préservation de l’autonomie des seniors, la pratique régulière d’activités physiques semble être un moyen efficace pour ralentir les effets délétères du vieillissement cérébral, notamment grâce à une amélioration de l’efficacité des mécanismes de neuroplasticité. Selon cette hypothèse neurotrophique, plusieurs neurotrophines libérées au cours de l’exercice, dont le facteur neurotrophique dérivé du cerveau (BDNF), participeraient au maintien de l’intégrité du système nerveux au cours du vieillissement. Cependant, le taux de sécrétion de ces neurotrophines est aussi sous le contrôle de gènes. Par exemple, une des formes du gène régulant la sécrétion du BDNF induit une moindre sécrétion cérébrale de la protéine et conduit à une moins bonne performance cognitive. Cette revue de questions a pour principal objectif de faire le bilan des études ayant montré un effet modulateur du gène du BDNF sur la cognition. Elle cherche également à montrer tout l’intérêt d’une approche génétique dans la compréhension des mécanismes qui sous-tendent la relation entre activité physique et cognition. Elle propose enfin quelques voies de recherches futures en s’appuyant sur cette approche interdisciplinaire combinant génétique, neurosciences cognitives, psychologie de l’exercice et physiologie humaine.
The Effect of Circular Saw Blade Clamping Diameter on its Resonant Frequencies
Authors: Kaczmarek Anna , Orłowski Kazimierz , Javorek Lubomir
Published: June 2016

In this paper results of comparison of characteristic resonant frequencies of circular saw blades as a function of the saw clamping diameter from the impact test are presented. Obtained results revealed that proportionally with the increase of the saw clamping diameter also the dynamical stiffness of the saw blade increased. As a consequence of that the resonant frequencies of the saw blade move to higher values. Moreover, with the increase of the saw blade clamping diameter for higher frequencies of forcing vibrations of the saw blade the amplitude of vibration are expected to be decreased.

Published: June 2016

An innovative software has been developed to measure and identify energy flow for multiple loads and sources like Grid and or other renewables. Algorithms have been developed to indicate status of energy used within a building unit and the Smart Gird as a whole. The software is developed on the AngularJS bases in the model-view-controller (MVC) platform using PHP language and MySQL is used as database for recording the data. The results of this research can support Electricity Generating Authority of Thailand (EGAT) for future grid planning and can be helpful for adaptive forcasting in connection with the consumption and generation. In the future, this software could be applied to improve the functions of energy management system (EMS) in the homes, buildings, and offices.
Analysis of the Impact of Distributed Grid-Connected PV System on Power Quality of the Electrical Distribution Network
Authors: Yee Myat Mon , Sirisamphanwong Chatchai
Published: June 2016

Electricity generation from solar energy by using PV cells is drastically increased due to global warming concern, greenhouse effect, and quality of living standards. However, PV generation may offer variable and unpredictable energy output due to intermittent nature of solar irradiance and hence, integration of PV into grid may provide some drawback effect to the power system. The aim of this paper is to investigate the impact of grid connected PV system on the power quality of distribution network. The power quality analysis is based on real measurements of 10 kWp, Energy Park SERT, School of Renewable Energy, Naresuan University, Thailand. Parameters such as active and reactive power, voltage, current, power factor, THDv, THDi, individual harmonic voltage and harmonic current are observed for the investigation of the interaction between SERT PV system and distribution network’s power quality. According to the measured data, PV system operation is negligible in terms of voltage distortion, voltage magnitude and frequency variation. Therefore, it can be noticed that 10 kWp SERT PV system does not effect on the distribution system power quality due to low PV penetration level.

A Photovoltaic rooftop system is being grown up for producing electricity in Thailand. The technical study of PV rooftop system is required especially in term of power quality impact from PV rooftop system to the grid system. The aim of this paper is to construct the simulation models of a micro grid PV rooftop system by using the simulation software PSCAD. PSCAD has an advantage that the software provides a complete model of the PV rooftop system in an electromagnetic transient software environment. The modules of study include PV array, three-phase inverter, LC filter, transformer, load, and distribution network. The constructed model is simulated under the Provincial Electricity Authority (PEA) regulations.
Development of Photocatalytic Conversion of Glucose to Value-Added Chemicals by Supported-TiO2 Photocatalysts
Authors: Roongraung Kamonchanok , Laosiripojana Navadol , Chuangchote Surawut
Published: June 2016

Biomass is an important renewable energy resource, which is used to replace the petroleum to produce chemicals. Glucose is a monomer of cellulose, which is the main component of biomass. In this work, conversions of glucose to value-added chemical by a simple method have been reported. TiO2 photocatalysts were fabricated by sol-microwave method. Value-added chemical production was successfully carried out via photocatalytic conversion of glucose with TiO2 photocatalysts. Arabinose, xylitol, gluconic acid, and formic acid were produced with photocatalytic reaction of TiO2 under UVA irradiation. The value-added products (gluconic acid, arabinose, and xylitol) can generally be further used as building blocks for biorefinery production, pharmaceutical production, and food industry. In the conventional sol-microwave method, the agglomeration of fabricated TiO2 particle was a limitation of photocatalytic activity. Therefore, the modification of TiO2 fabrication by use of zeolite as a TiO2 support was applied to increase efficiency of photocatalytic conversion of glucose and its selectivity. The effect of TiO2 dosage on zeolite (TiO2/zeolite) on photocatalytic activity and yield of products was monitored. The results from scanning electron microscopy (SEM) images indicated that zeolite supporter reduced agglomeration of spherical TiO2 particles. The well distribution of TiO2 particles on surface of zeolite particles could be observed in 15%TiO2/zeolite. It was found that the highest photocatalytic conversion of glucose (77.3%) was obtained from the use of 15%TiO2/zeolite as photocatalyst. The yields of gluconic acid, arabinose, xylitol, and formic acid were 8.6, 26.0, 3.7, and 33.89%, respectively.
Synthesis of Silica Gel and Development of Coating Method for Applications in a Regenerative Air Dehumidifier
Authors: Aimjaijit Winit , Chaiwiwatworakul Pipat , Chuangchote Surawut
Published: June 2016

In order to control humidity in air conditioning system, various desiccants are used to dehumidify air in air conditioners. One of simple methods, which can be used to coat desiccant materials on surface of heat exchanger in air conditioners, is dip coating. Typical, desiccants used in dehumidifying system is silica gel in a form of solid-state powder. This powder has low adhesion with the heat exchanger surface. To improve adhesion of the silica gel powder, some glue is generally applied on the surface of heat exchanger. The dehumidification properties of silica gel, however, will be remarkably reduced because of less surface area of silica gel powder. Instead of silica powder, this work aims to synthesize silica gel using sol-gel method, which the sol-state material can be suitably used in dip coating. In experimental study, silica gel was synthesized by sol-gel method of precursors with 1 M sulfuric acid (H2SO4). The pH was adjusted using sodium silicate solution (Na2O(SiO2)x.xH2O) and rinsing with DI water. Surface area, pore volume and size, phase composition, morphology, and percentage of moisture adsorption of the synthesized silica gel were characterized. Silica gel fabricated with pH 5 showed the highest percentage of moisture adsorption compared with other samples. In addition to the highest percentage, silica gel with pH 5 could adsorb water up to 28 times of its own weight. X-ray diffraction (XRD) results showed that Na2SO4 impurity were successfully eliminated after rinsing with DI water more than 4 times. Finally, adhesive property of silica gel on aluminium-fin samples was tested with scalloped tape-test method. It was observed that, to improve the adhesion property of silica gel on the aluminium fins, prior to dipping of silica gel, the fins should be etched with sulfuric acid. The acid can adjust the surface of fines to be much rougher.

This technology is likely to investigate the influence of clerestory aperture on the performance of daylighting collector in term of the interior daylight illuminance distribution by using the lighting tool AGi32. The empirical correlations from the use of anidolic configurations for tropical sky are proposed with high confidence interval (>85%).
A Dilatometric Study of the Non Isothermal Aging of a Cold Rolled Al-Mg-Si Alloy
Authors: Hayoune Abdelali
Published: June 2016

In contrast to isothermal aging, few reports document the non-isothermal aging of deformed Al–Mg–Si alloys. The knowledge of non-isothermal aging of pre-deformed Al–Mg–Si alloys is of primary importance to understand the thermal stability as well as to control the microstructure of the final product during industrial processing. Therefore, the present work has been focused to understand the microstructure evolution during the continuous heating of a cold rolled Al–Mg–Si alloy. This has been followed using dilatometry, Differential Scanning Calorimetry, X-Ray Diffraction and microhardness measurement. Based on the results obtained, it is shown that dilatometry is a powerful tool to study phase transformations in deformed Al-Mg-Si alloys, moreover, the microstructural evolution, of the cold rolled sample, can be described as follows: at the earlier stages of the non-isothermal aging, formation and then the reversion of fully coherent GP zones take place. This is followed by the simultaneous occurrence of β” and β’ precipitation and recovery reaction. By continuing aging, the next reactions which will take place are β” and β’ dissolution and recrystallization. Finally, one can observe the formation and then the dissolution of the equilibrium phase β.

Nanotechnology has significant contributions on developing modern industries, such as electronics, biomedical, materials, manufacturing, and energy industry. The changes introduced by nanotechnology, have currently extended to several areas for oil and gas industry, namely exploration, drilling, production, refining and enhanced oil recovery (EOR). This study focuses on attraction to the worldwide attention of nanotechnology and how this method effects oil breakthrough and improves EOR. This Study also implies that parameters such as rock types, crude oil types, nanoparticle types, concentrations, and sizes, have significant factors on recovery factor (RF) through improving key-parameters such as oil relative permeability, interfacial tension (IFT), wettability, transmissibility and particles retention.
Mass Transfer Behaviour in Hybrid Solvent Oil Recovery Processes
Authors: Lorimer Shelley , Boehnke Ryan , Meza Brigida
Published: June 2016

The mechanisms of mass transfer in thermal solvent enhanced oil recovery processes and the influence of grid size in the numerical simulation of these processes is not well understood [1, 2]. The literature has indicated that, experimentally, solvent fronts progress more rapidly that what can be predicted using current approximations [3]. It has also been shown that under certain modelling conditions with coarser grid meshes, the influence of numerical errors can be substantial. The equations that govern thermal/solvent multiphase flow through porous media are extremely complex and it is very difficult to decouple the contribution of the mass transfer mechanisms from the thermal effects. This paper was written to increase the understanding of the mass transfer mechanisms in hybrid thermal solvent recovery processes through sensitivity study using a numerical solution of the linear one dimensional advection diffusion/dispersion (ADD) equation. This equation was modeled using finite difference methods. The effects of grid size were examined to verify the use of this method, and the results were then used to examine the sensitivity of the equation to the parameters that govern the mass transfer mechanisms (advection velocity, diffusion and dispersion coefficients).In particular, a range of values for diffusion and dispersion coefficients were selected for the sensitivity study, and one advection velocity. These values were then used to numerically solve the ADD equation to assess the impact of each mechanism (advection, diffusion and dispersion) and their contribution to the movement of the solvent front. The parameters chosen for this study were based on values obtained from the literature for advection velocity, diffusion and dispersion coefficients consistent with a gravity drainage thermal/solvent oil recovery process. This sensitivity study has indicated that all three mechanisms (advection, diffusion and dispersion) must be included to have the solvent front progress at rates that are consistent with experimental solvent front advance rates published in the literature to date [1]. This result suggests that diffusion alone cannot account for the movement of the solvent front within the ranges of values that have been studied.

In the paper are presented the tests carried out on the specimens made of boot laser welded joints of high strength ferritic steel S960QC. The tensile properties materials for materials the weld, heat affect zone and base of welded joints were determined. For verification of strength welded joints during tensile test and registration of the strain fields created during joint loading used the optical video system Aramis. On the basis of strains, and using the true strain-stress dependencies, the stresses in the weld material and in the base material at the area of the occurrence of strain localization were determined.
Fatigue Life of Welded Joints of High-Strength Structural Steel S960QL
Authors: Slezak Tomasz , Sniezek Lucjan
Published: June 2016

The article presents the results of research on low cycle fatigue strength of welded joints of structural steel S960QL. Two types of butt welds were analysed: I-joints and V-joints. The tests were performed under load controlled using the total strain amplitude εac. Fatigue life analysis was conducted based on the Manson-Coffin-Basquin equation, which made it possible to determine fatigue parameters. High concordance was found of the adopted description model with experimental results. Studies have shown differences in the fatigue life of the various joints analysed, wherein I-joints showed about 20-50% higher fatigue life. Fractographic tests of fatigue fractures in joints revealed the details of fatigue cracking and differences in the propagation rate of fatigue cracks.

This work presents results of the experimental fatigue analysis of the compressor blades. In the investigations the blade with the V-notch (which simulates the foreign object damage) was considered. The notch was created by machining. The blades during the fatigue test were entered into transverse vibration. The crack propagation process was conducted in resonance conditions. During investigations both the amplitude of the blade tip displacement and also the crack length were monitored. As the results of presented investigations both the number of load cycles to crack initiation and also the crack growth dynamics in the compressor blade subjected to resonant vibrations were determined. In the work the influence of crack size on the resonant frequency was also investigated.
The Influence of Microstructural Defects on the Stress State of S235JR Steel under Plastic Deformation
Authors: Kossakowski Paweł Grzegorz
Published: June 2016

This paper analyzes the changes in the state of stress in the plastically deforming structural steel which are attributable to the evolution of defects in the microstructure of the material. Numerical simulations were conducted to study the behaviour of a structural element under tensile stress using the Gurson-Tvergaard-Needleman material model for porous media. The model can be employed to assess the effects of microstructural phenomena on the strength of a material under plastic deformation. The main aim of the analysis was to determine the relationship between the changes in the triaxial state of stress and the changes in the volume fraction of voids, characterizing the material porosity.
Spotted fever group rickettsia in ticks infesting humans, wild and domesticated animals of Sri Lanka: one health approach

Published: June 2016

Spotted fever group rickettsial infections are considered an emerging infectious disease in Sri Lanka. The present study examined the potential role of tick vectors carrying the infection from sylvatic reservoirs to humans via domesticated animals. Ticks infesting humans, dogs and wild animals were collected island-wide and were identified. Presence of spotted fever group rickettsia in the tick blood meal was determined using PCR in a sub-sample of ticks collected. A total of 30,933 ticks were collected from 30 different hosts and free living stages from the ground.  The collection consisted of 25 tick species recording 12 species from humans, 19 from domesticated animals and 22 from wild animals. Of the total collection randomly selected a sub-sample of 80 ticks were used to identify rickettsia pathogens. This comprised of  fifty ticks from 50 wild animals  belonged to 15 species (wild boar, pangolin, porcupine, barking deer, star tortoise, mouse deer, samber, spotted deer, monkey, civet cat, bandicoot, elephant, fishing cat, rabbit, flying squirrel; and 20 ticks from 15 dogs especially from areas where spotted fever cases were reported and 10 ticks from 10  humans. Results showed that rickettsial infections were found in four tick species, Amblyomma testudinarium collected from a wild boar, Riphicephalus sanguineus from a dog, Amblyomma clypeolatum from a star tortoise and Amblyomma javanense from a pangolin.  Except for A. javanense, other three tick species are generalists infesting humans as well as domestic and wild animals. There is a high potential that these infections can spread easily to humans via the domesticated animals. This is the first report of ticks infesting domesticated and wild animals carrying spotted fever rikettsia and it underscores the possibility of spread of infection from wild reservoirs to human in the animal/human health interface.
Community-based tourism: From a local to a global push
Authors: Giampiccoli Andrea , Saayman Melville
Published: June 2016

Orientation: World inequality is growing and tourism contributes to it; an alternative option is, therefore, needed towards a more just and redistributive approach to this industry.Purpose: The aim is to propose that there is a need to advance the tourism sector to be more in line with community-based tourism (CBT) principles and practices.Motivation of the study: The current tourism system exists within the more general neoliberal milieu. Alternative tourism forms are also often co-opted and circumscribed by a neoliberal framework. The issue is to a find a possible solution to advance a tourism development approach that enhances a decrease in inequalities.Research design, approach and method: The article is a review paper.Main findings: The results propose that the actual system of the tourism sector is in line with neoliberal milieu and does not militate against various inequalities (it, in fact, supports them). Therefore, a tourism development approach more based on CBT principles and practices is advocated. Practical/managerial implication: A shift in the tourism development approach is proposed, reflecting the need to establish new policies and management structures that are fundamentally based on CBT principles and practices.Contribution/value add: The article contributes to the literature related to the role of tourism in development, specifically debating matters related to the relationship between tourism, neoliberalism and alternative tourism. In addition, the article also deals with the debate on CBT.

Representation and Sensibility. The Rancière-Lyotard Debate on Art

If representation means making something present again, what is its relationship to sensibility, especially in art? Could the work of art represent our sensory inputs, or does such representation always fall short of the adequate re-presentation of the sensory? The debate on representation and sensibility has been reopened within a new framework with Rancière’s distinction between three historical regimes of art. This article sets out by casting doubt on Rancière’s assumption that representation could be reduced to one of these three regimes. Secondly, discussion turns to Rancière’s criticism of Lyotard’s notion of unrepresentability, particularly with regard to ‘Auschwitz’. Thirdly, the question is put why these two authors have such different readings of Kant’s aesthetics: Rancière’s choice for beauty is actually a choice for representation, whereas to Lyotard, the unrepresentable sublime creates the space for the event in our sensibility. Finally, it is shown that Rancière, though acknowledging a tension between ‘spirit’ and ‘letter’, ignores the meaning of avant-garde art, whereas Lyotard distrusts realistic, representative art.
The nominalization of Dutch particle verbs:
Schema unification and second order schemas
Authors: Booij Geert
Published: June 2016

The event nominalizations of Dutch particle verbs and other types of separable complex verbs are not derivations from particle verbs, but compounds nouns, with a deverbal head preceded by a word that functions semantically as a modifier of the verbal base of the head noun. This structural analysis explains two empirical generalizations: (i) simplex verbs allow for nominalization with -ing when embedded in compounds; (ii) particle verbs have corresponding nominalizations with the same unproductive type of nominalization as the corresponding simplex verbs.

In order to account for these generalizations, the following related concepts from the theoretical framework of Construction Morphology are used: the representation of word formation patterns by means of constructional schemas (in which form-meaning asymmetries can be specified), schema unification (with unified schemas having their own degree of productivity), constructional idioms (constructional schemas with lexically filled slots), and second order schemas. Thus, this case study illustrates the descriptive power of Construction Morphology.

Dutch Female Personal Names

In this paper I argue that the formation of female personal nouns in Dutch provides no argument for so-called ‘paradigmatic’ means of word-formation. In the literature (Van Marle 1985, 1986) it has been argued that these nouns in particular provide an argument for paradigmatic word-formation. More in particular, Van Marle observes that female nouns in –ster only exist if there is a neutral personal noun in –er. He therefore concludes that in order to form female personal nouns in –ster, the grammar needs to check whether there is an existing word in –er. However, it can be demonstrated that such means are superfluous once we acknowledge that –er is the realization of a more abstract morpheme, which potentiates the affixation of a morpheme deriving female nouns, realized as –ster. Second, that Dutch hosts a haplology rule that deletes –er immediately before –ster. Since haplology is independently motivated (see e.g. Yip 1998, Nevins 2012), the present contribution provides an argument against paradigmatic means for word-formation.
Vaders en voorlezen

Samenvatting

In de afgelopen decennia is het wetenschappelijk onderzoek naar de
invloed
van vaders op de ontwikkeling van kinderen toegenomen. Vaders
spelen een belangrijke rol in het leven van kinderen (Amato & Sobolewski,
2004; Lamb, 1997; Marsiglio, 1995).

Het is bekend dat voorlezen een positief effect kan hebben op de taal- en
geletterdheidontwikkeling van jonge kinderen (bv., Bus, van Ijzendoorn &
Pellegrini,
1995; Fletcher & Reese, 2005). Onderzoek naar voorlezen richt
zich echter voornamelijk op moeders en er is weinig bekend over vaders
en voorlezen. Dit onderzoek richtte zich op voorlezen door ongeveer 800
vaders en moeders met jonge kinderen in lage-inkomens gezinnen in de
Verenigde Staten.
Vaders en moeders werden gevraagd naar hun voorleesfrequentie.
Van de moeders gaf bijna 60% aan dat ze dagelijks voorlazen
toen hun kind twee en drie jaar was. Van de ondervraagde vaders las bijna
een kwart dagelijks voor, en rond de 30% wekelijks. Kinderen wiens vaders
regelmatig voorlazen toen ze twee en drie jaar waren hadden betere cognitieve-
en taalvaardigheden
op 3-jarige leeftijd. Vaders die vaak voorlazen
hadden ook kinderen met betere boekkennis en boekbegrip op 5-jarige leefijd
vergeleken met vaders die minder vaak voorlazen. Het opleidingsniveau
van de ouder, de thuistaal en het geslacht van het kind speelde ook een belangrijke
rol bij het effect van voorlezen op de ontwikkeling van kinderen.
Voorlezen door moeders had voornamelijk een effect op de cognitieve- en
taalvaardigheden en boekbegrip van kinderen op 3-jarige leeftijd. Er was
geen significant effect op de boekkennis van kinderen (op 2- en 3-jarige
leeftijd).

Samenvatting

Het reguleren van de grenzen van privacy tussen jongeren en ouders is
moeilijk, aangezien jongeren steeds trachten de grenzen van hun privédomein
te verruimen. Als jongeren het idee hebben dat hun ouders de
privacygrenzen overtreden kan dit leiden tot conflicten, maar een hoger
niveau van conflicten zou er ook aan kunnen bijdragen dat jongeren een
toenemend gevoel hebben van privacyschending. Deze multi-informant
longitudinale studie (N = 309) onderzocht relaties tussen percepties van
privacyschending en het niveau van ouder-kindconflict in de adolescentie.
Bidirectionele relaties werden aangetoond. Privacyschending voorspelde
hogere niveaus van ouder-kindconflict over tijd, en conflicten voorspelden
ook gevoelens van privacyschending. De richting van deze effecten
varieerde tussen de metingen en de verschillende informanten voor ouderkindconflict
(vader, moeder, of kind). Bevindingen worden bediscussieerd
vanuit het idee dat er mogelijk een functionele rol is voor conflicten in de
ouder-kindrelatie, omdat het aandacht kan vestigen op het overtreden van
privacy grenzen, maar dat conflicten niet erg effectief zijn in het reduceren
van toekomstige gevoelens van privacyschending.
