Divulgando nuevas ideas sobre la diversidad humana: la dimensión educativa del discurso sobre la discapacidad en la España franquista
Authors: Martínez-Pérez José , Del Cura Mercedes
Published: June 2019

A lo largo del Franquismo la discapacidad apareció inmersa en un complejo discurso en el que confluían, entre otras cosas, las ideas científicas, la sensibilidad hacia las personas portadoras de “deficiencias”, el interés económico, y el adoctrinamiento político. El objetivo de este trabajo es analizar el componente “educativo” de este discurso y poner de manifiesto cómo dicho ingrediente no estuvo únicamente dirigido a mejorar las condiciones de vida de las personas catalogadas de “inválidas”, sino que pretendió también obtener el compromiso, la colaboración y la complicidad del conjunto de la ciudadanía para establecer medidas destinadas a reducir el impacto negativo que, según se sostenía, provocaba la discapacidad. Así mismo, mostraremos cómo dicho discurso, que en ocasiones adquirió tintes propagandísticos, contribuyó a que en la España franquista creciese una forma de contemplar la discapacidad que no siempre fue favorable a los intereses de las personas con discapacidad.
"Ciprés, el triunfador". El bosque andino patagónico, la ciencia, la moral y la salud social en Argentina entre fines del siglo XIX y la década del ‘30
Authors: Gabriela Núñez Paula , Lema Carolina
Published: June 2019

Este trabajo, inscripto en la historia de las ciencias, recorre cómo, en el reconocimiento científico del bosque andino patagónico argentino, se introducen valoraciones que ubican al mismo como parte de la salud social, que redunda en la jerarquización asimétrica de la población. Se revisan los escritos de los primeros naturalistas que, desde fines del siglo XIX, observan el espacio, y se avanza tomando estudios hasta entrada la década del ’30. El recorte temporal se extiende hasta el establecimiento de políticas de conservación, a partir de la creación del Parque Nacional Nahuel Huapi, en 1934. La mirada sobre la ciencia indaga en las tradiciones de estudio de los diferentes grupos de especialistas que escriben sobre el espacio, y el modo en que estas investigaciones dialogan con políticas concretas de apropiación e intervención, que no se circunscriben a las prácticas internas de la biología de estos años, sino que se encuentran atravesadas por las concepciones organicistas desde las cuales se diseña la salud social. A lo largo de estas páginas se caracterizan las tradiciones de investigación en biología y se encuentra que las políticas trasladan, desde la mirada sobre la salud, los principios de conservación y uso social del bosque.

Du vin antique sur un versant haut-savoyard ? Le vignoble et le pressoir de Versoie à Thonon-les-Bains
Authors: Landry Christophe
Published: June 2019

Les vestiges d’une petite occupation rurale des
ive et ve siècle apr. J.-C. ont été fouillés en
2014 au bord de l’ancien marais de Versoie, au nord du massif du
Chablais. L’étude du site permet de restituer une parcelle de vigne et
un bâtiment abritant un pressoir à levier. Il s’agit d’un nouveau
jalon dans l’histoire de la viticulture alpine, à l’heure où les
données archéologiques savoyardes sont encore très lacunaires. Doit-on
voir le vignoble de Versoie comme une attestation du fameux cépage vitis allobrogica ou vitis picata dont Pline nous
dit qu’il est productif et affectionne les lieux froids, alors que les
sites de production sont plutôt attendus aujourd’hui dans une région
plus centrale de la cité de Vienne ? Ce cépage pourrait ne pas s’être
pérennisé dans le Chablais, les moines introduisant la culture du
Chasselas en « crosses » (hautains) au xie siècle sur la rive sud du Léman, et ce
cépage ne s’y généralisant que dans la première moitié du xve siècle.
Rôle méconnu d’une brèche rouge brun à clastes schisteux et à ciment silico-ferrugineux dans le bâti médiéval des Pyrénées catalanes
Authors: Martzluff Michel , Giresse Pierre , Catafau Aymat , Barrau Caroline de , Respaut Cécile
Published: June 2019

Issue de la surface de plusieurs formations
schisteuses paléozoïques des Pyrénées catalanes, une brèche ocre à
rouge sombre est signalée et définie ici pour la première fois. Elle
est caractérisée par des clastes de schistes sériciteux inclus dans un
ciment silico-ferrugineux dont plusieurs structures témoignent d’un
processus de pédogenèse ferrallitique qui pourrait remonter au
Miocène. Elle a visiblement joué, du xe au
xiie siècle, un rôle de premier plan dans
l’ornementation d’un petit groupe d’édifices médiévaux proches des
rarissimes gisements. Dans les Albères et les Aspres, entre 100 et
250 m d’altitude, se détache un groupe de monuments prestigieux
(monastère de Sant Quirze de
Colera, château vicomtal de Castelnou des comtés de Peralada-Empuries et de Besalu-Vallespir). Mais le
groupe le plus important se trouve au cœur de la chaîne, entre 1 400
et 2 000 m d’altitude, dans le comté de Cerdanya-Conflent. L’apparition précoce de
cette roche dans ces sanctuaires montagnards interroge sur les motifs
de son usage localisé et de son abandon au cours du xiie siècle.
Remploi et mobilité des bois de construction dans le bâti subalpin médiéval et moderne : le cas du massif du Mercantour (Alpes françaises)
Authors: Labbas Vincent
Published: June 2019

L’approche dendrochronologique et archéologique
des constructions subalpines agropastorales dans le massif du
Mercantour met en évidence un bâti utilisé et reconstruit fréquemment
du xiie siècle jusqu’au début du xxe siècle en exploitant les ressources
forestières environnantes. La pratique systématique du remploi dans
ces édifices de haute montagne implique une mobilité des matériaux. Ce
déplacement des pièces de bois induit une réutilisation de matières
premières in situ,
interne à un bâtiment, mais peut se traduire également par un
déplacement des pièces pour construire d’autres bâtiments
agropastoraux, qu’ils soient proches ou éloignés. Cette recherche
interdisciplinaire met en évidence des pratiques de construction dans
lesquelles la mobilité des matériaux transparaît autant que l’emploi
de bois « neuf ». Elle montre une économie dans les moyens mis en
œuvre ainsi que dans l’usage des ressources forestières locales.
Marchands du Dauphiné à Bayonne et dans sa région au milieu du xviie siècle
Authors: Brumont Francis
Published: June 2019

Au milieu du xviie siècle, une importante colonie de
marchands dauphinois, originaires pour la plupart de l’Oisans, est
installée à Bayonne et dans sa région. Même si l’on peut recenser
quelques colporteurs, la plupart sont des marchands en gros, regroupés
en compagnies familiales et/ou associés avec d’autres Dauphinois, qui
traitent avec des détaillants dans la région ou en Espagne, se
cantonnant généralement à ces activités commerciales. La plupart ont
gardé de solides relations avec le pays natal d’où viennent leurs
épouses ainsi qu’avec Lyon où sont installés nombre de leurs
compatriotes et d’où provient une bonne partie de leur
marchandise.
Mobilité et ancrage local : les enjeux des confréries à Turin au xviiie siècle
Authors: Rolla Nicoletta
Published: June 2019

Durant les années de paix entre le Traité
d’Utrecht (1713) et la Guerre de Succession d’Autriche (1742),
l’ouverture de plusieurs chantiers à Turin et dans le Piémont
constituait une opportunité d’investissement pour les entrepreneurs du
bâtiment provenant des Alpes nord-occidentales. Centre de négociation
des commandes publiques, Turin était l’épicentre d’une circulation
plus vaste vers les différents chantiers piémontais. Dans ce contexte,
l’activité des confréries était cruciale dans le processus
d’installation en ville. À Turin, on connaît l’existence de deux
confréries « nationales » des maîtres maçons de Lugano et de Milan, et
des maîtres charpentiers de Graglia et Muzzano. Cet article porte sur
le rôle de ces confréries dans la mobilité des migrants. Il vise à
montrer le processus complexe et conflictuel de construction de
l’appartenance à la « nation » – suisse, milanaise, biellese – et de définition des communautés
des immigrés.
Le développement en co-construction par les migrations familiales (canton de Villard-de-Lans xixe-xxe siècle)
Authors: Della-Vedova Gilles
Published: June 2019

Réservoirs de populations prolifiques, les
montagnes sont perçues comment alimentant des migrations descendantes
selon une trajectoire rectiligne. Une étude menée à partir des actes
de l'état civil et des recensements dans un canton de montagne proche
de la ville permet de préciser, nuancer et contester cette lecture.
Préciser puisqu'il est possible d'identifier celles et ceux qui
descendent. Les clés de compréhension passent par la composition des
familles en montagne et celles déjà installées en ville. Nuancer car
les circulations connaissent des étapes et des temporalités à repérer.
Le creeping est à revoir
et les circulations sont à apprécier en fonction des activités
exercées. Il faut enfin contester la descente par les migrations de
retour. À côté des migrations vers le bas, le développement repose sur
d'autres situations qui partent des bas pays vers les régions
d’altitude mais également des circulations entre les massifs
montagnards à différentes échelles.
La mobilité des Savoyards aux portes de la Maurienne (1860-1914)
Authors: Villermet Jean-Marc
Published: June 2019

Cet article concerne le phénomène migratoire à
l’échelle d’un village de montagne, en Savoie, et des communes
alentour. Le territoire est a
priori géographiquement enclavé. Malgré tout, des relations ont
eu lieu entre les vallées. Comment se sont-elles mises en place ?
Quels furent les effets de cette situation sur le fonctionnement de la
société locale ? À partir des registres de matricules déposés aux
archives départementales de la Savoie et des sources privées, une
étude fut menée sur une cohorte de 977 hommes, représentant
pratiquement autant de familles différentes. Mobiles sur le territoire
national voire international, ils voyagèrent à l’étranger dans une
dimension européenne et intercontinentale. Se déplacèrent-ils toujours
seuls ou bien furent-ils accompagnés par des membres de leur famille,
par des femmes et des enfants ?
Encadrer la coutume migratoire : l’exemple de la transhumance pyrénéenne dans la première moitié du xxe siècle
Authors: Pinoteau Henri
Published: June 2019

La transhumance est sans doute une des plus
anciennes formes de circulations montagnardes périodiques. Au-delà de
la question pastorale, elle peut aussi s’envisager sous un angle
administratif et international. Si la mise en œuvre de la circulation
d’animaux domestiques dans un cadre montagnard frontalier fut
longtemps une affaire locale basée sur la coutume, la situation évolue
largement au début du xxe siècle. Les archives de
l’administration du ministère de l’Agriculture font en effet
apparaître le besoin grandissant de l’État d’en connaître davantage,
d’encadrer voire d’institutionnaliser ces pratiques, en codifiant
l’usage de l’espace montagnard. Le but est avant tout d’éviter les
épizooties. On propose donc de montrer comment l’État s’y est pris
pour lutter contre ces fléaux que la transhumance ne pouvait
qu’aggraver, par des mesures à la fois diplomatiques, administratives
et sanitaires.
Les figues d’exportation en Kabylie (1930-1953) : réussite ou échec du colonisateur ?
Authors: Chiavassa Isabelle
Published: June 2019

L’émergence de l’innovation technique est
constatée en Kabylie, dans l’Algérie française, massif montagneux
marqué par une agriculture très modeste, inséré toutefois dans
l’économie marchande. Les archives des communes mixtes et des
sous-préfectures, aux Archives nationales d’outre-mer, témoignent de
l’action du colonisateur : des conseillers agricoles tentent de
promouvoir un nouveau mode de séchage des figues, la construction de
hangars de séchage, des méthodes plus « industrielles ». Après des
démonstrations organisées dès 1930, l’administration coloniale
favorise l’installation d’ateliers. Elle constate un échec relatif
vers 1953 ; les paysans ont parfois des réticences. L’innovation exige
de convaincre les producteurs et de financer des coopératives.
L’administration souhaite exporter plus de figues sèches en métropole.
Dans ce discours colonial, l’espace montagnard est perçu comme espace
de résistance au changement, mais les fellahs « s’ouvrent aux idées
coopératives ».
La montagne touristique française : une démographie en panne ?
Authors: Gauchon Christophe
Published: June 2019

Lorsque les politiques d’aménagement touristique
de la montagne ont été lancées dans les décennies 1950-1960, elles
visaient à développer les activités économiques, mais aussi à enrayer
le déclin démographique. Ces buts ont d’abord semblé être atteints.
Mais depuis une vingtaine d’années, de nombreuses communes-supports de
stations enregistrent des soldes migratoires négatifs : sur un
échantillon de 88 communes-supports de stations de sports d’hiver des
Alpes du Nord (Isère, Savoie, Haute-Savoie), 55 ont été dans cette
situation entre 2009 et 2014. Contrairement à de nombreuses stations
littorales, l’attractivité touristique en montagne ne s’est pas
accompagnée d’une attractivité résidentielle ; et les populations
permanentes installées dans les stations d’altitude ont du mal à faire
souche au-delà de la génération des pionniers. L’augmentation des prix
du foncier et l’hyperspécialisation de cette économie touristique
engendrent pour les jeunes actifs une difficulté à s’installer et à
vivre en station.
Estatística, biologia evolutiva e eugenia: As publicações do jovem Ronald Fisher em The Eugenics Review (1914-1919)
Authors: Carvalho Leonardo Dallacqua de
Published: June 2019

Este artigo analisa em perspectiva histórica a discussão eugênica do estatístico inglês Ronald Aylmer Fisher no início da sua trajetória profissional. Entre 1914 a 1919, Fisher publicou artigos e revisões de livros na revista especializada The Eugenics Review, na qual expunha a viabilidade do pensamento eugenista. Por meio de tais fontes investigo de que modo estatística e biologia evolutiva estavam ligadas às suas propostas eugênicas e qual era o contexto científico da eugenia nas primeiras décadas do século XX.
“Na linguagem clara e compreensível do povo”: História e cotidiano politizado nas poesias de lundus (Rio de Janeiro, segunda metade do século XIX) .
Authors: Martins de Souza Silvia Cristina
Published: June 2019

Este artigo explora as relações entre história e literatura considerando a literatura um testemunho que pode ser lido, desconstruído e submetido ao mesmo escrutínio ao qual os historiadores submetem outras fontes que lhes permitam ter acesso à compreensão de redes e tensões sociais mais amplas. Nele são utilizadas poesias publicadas no cancioneiro Trovador: coleção de modinhas, recitativos, árias, lundus, etc.. (1876), com o objetivo de mostrar como seus autores estabeleceram um diálogo entre si e com seus leitores acerca de um assunto candente do seu tempo - o progresso e seus desdobramentos para o cotidiano da sociedade – utilizando-se da literatura como instrumento de intervenção na realidade. A partir desses pressupostos, a experiência histórica vivida por escritores é considerada condição básica de análise, bem como texto e contexto são percebidos como dimensões indissociáveis de um fenômeno mais amplo que é ao mesmo tempo, cultural, econômico, social e político devendo ser abordados em conjunto levando-se em conta suas conexões recíprocas.
História de Polifemo: entre vida primitiva e idade de ouro
Authors: Santos Vladimir Chaves dos
Published: June 2019

O encontro do herói Odisseu com o ciclope Polifemo na Odisséia de Homero em dado momento saiu do terreno do mito e chegou até o da história. Polifemo tornou-se uma figura do mundo primitivo, em que reina violência, antropofagia, irracionalidade, paixão e música. O problema do valor da vida primitiva na antiguidade clássica conduzia a dois pólos antagônicos de interpretação. De um lado, a perspectiva progressista que via na história a saída de um estado primitivo e selvagem através da técnica. De outro lado, a perspectiva decadentista, segundo a qual os primeiros homens viveram no melhor dos mundos, na idade de ouro. O expediente de síntese dessas concepções opostas resulta num retrato ambíguo do mundo selvagem e primitivo. O presente artigo pretende situar alguns autores dentro dessa problemática. Protágoras, Eurípides e Crítias compartilhariam o quadro da vida ciclópica de Homero. Teócrito, Ovídio e bem mais tarde Góngora, por outro lado, estariam inseridos na tradição da idade de ouro, que vem desde Hesíodo. Por fim, alguns autores preferem destacar as ambigüidades da vida selvagem e primitiva, tal seria o caso de Platão, Montaigne e Vico.
literaturas de fronteira: companheiros (d)e viagens à URSS no Brasil contemporâneo (1940-1960)
Authors: Palamartchuk Ana Paula
Published: June 2019

No cenário literário brasileiro do início da década de 1950, chama a atenção a publicação quase simultânea de O mundo da paz (1952) e Os subterrâneos da liberdade (1954) de Jorge Amado, e Viagem (1954) e Memórias do cárcere (1954) de Graciliano Ramos. Romancistas brasileiros já consagrados pela crítica e pelo público, ambos revelam nessas publicações a radicalidade com a qual se identificam com o comunismo e com a experiência soviética. Ao mesmo tempo, os relatos de viagem e os livros de memória, se vistos em conjunto, evidenciam a presença de duas tradições narrativas: a literária propriamente dita e a do engajamento político dos intelectuais. Assim, o que se pretende aqui é apresentar como essas duas tradições aparecem na obra dos dois escritores, em especial, em seus relatos de viagem à URSS. Do ponto de vista da militância política e dos recursos literários, ambos escritores se utilizaram, nesses títulos, do “gênero de fronteira” para partilhar com seus leitores algum tipo de comprometimento com a história da política nacional recente, com o comunismo e para avalizar a experiência soviética.

Published: June 2019

In this article, the analyses of free vibration of nanoplates, such as single-layered graphene sheets (SLGS), lying on an elastic medium is evaluated and analyzed via a novel refined plate theory mathematical model including small-scale effects. The noteworthy feature of theory is that the displacement field is modelled with only four unknowns, which is even less than the other shear deformation theories. The present one has a new displacement field which introduces undetermined integral variables, the shear stress free condition on the top and bottom surfaces of the plate is respected and consequently, it is unnecessary to use shear correction factors. The theory involves four unknown variables, as against five in case of other higher order theories and first-order shear deformation theory. By using Hamilton’s principle, the nonlocal governing equations are obtained and they are solved via Navier solution method. The influences played by transversal shear deformation, plate aspect ratio, side-to-thickness ratio, nonlocal parameter, and elastic foundation parameters are all examined. From this work, it can be observed that the small-scale effects and elastic foundation parameters are significant for the natural frequency.
3D Simulation Investigating ZnO NWFET Characteristics
Authors: Ditshego Nonofo M.J. , Sultan Suhana Mohamed
Published: June 2019

3D Simulation was carried out and compared with fabricated ZnO NWFET. The device had the following electrical output characteristics: mobility value of 10.0 cm2/Vs at a drain voltage of 1.0 V, threshold voltage of 24 V, and subthreshold slope (SS) of 1500 mV/decade. The simulation showed that the device output results are influenced by two main issues: (i) contact resistance (Rcon ≈ 11.3 MΩ) and (ii) interface state trapped charge number density (QIT = 3.79 x 1015 cm-2). The QIT was derived from the Gaussian distribution that depends on two parameters added together. These parameters are: an acceptor-like exponential band tail function gGA(E) and an acceptor-like Gaussian deep state function gTA(E). By de-embedding the contact resistance, the simulation is able to improve the device by producing excellent field effect mobility of 126.9 cm2/Vs.
Spectroscopic and Structural Dynamics of MoS2 Thin Films
Authors: Usman Arslan , Karamat Shumaila , Sattar Abdul , Ashfaq Afshan , Rafique Muhammad , Dawes Judith
Published: June 2019

A promising two-dimensional material for applications in optoelectronic and photonics, MoS2 is in focus since last decade. Its optical, structural and electronic properties are of practical importance along with its exciton dynamics. MoS2 thin films were synthesized with Chemical Vapour Deposition (CVD) technique on Si/SiO2 substrates. The thickness dependent regularities were controlled and examined to quantitatively control the film quality with thickness variation. Various characterization techniques were employed to investigate structural and morphological changes induced systematically to reveal the van der waal stacked layers of MoS2 material. The In-plane characteristic mode E12g and out of plane A1g vibrational modes were detected in different configurations of film’s structure. Optical absorption spectra gave us information on photon energy with the absorbance; extrapolation of this curve gave optical bandgap (Eg) in the form of Tauc plot. These energies can be associated to interband electronic transitions in the Brillouin zone. The intrinsic excitonic response as a consequence of layer stacking and velly indexing can be attributed to this change in bandgap from 1.68 to 1.91 eV. Surface morphology of the as-grown films also provides better understanding of MoS2 material with root mean square (RMS) roughness in the range of 1.32 to 3.85 nm.
The Effect of Homogenization Procedure on Mechanical Properties of High-Performance Concrete with Partial Replacement of Cement by Supplementary Cementitious Materials
Authors: Fladr Josef , Bily Petr , Šeps Karel , Chylík Roman , Hrbek Vladimír
Published: June 2019

High-performance concrete is a very specific type of concrete. Its production is sensitive to both the quality of compounds used and the order of addition of particular compounds during the homogenization process. The mechanical properties were observed for four dosing procedures of each of the three tested concrete mixtures. The four dosing procedures were identical for the three mixes. The three mixes varied only in the type of supplementary cementitious material used and in water content. The water content difference was caused by variable k-value of particular additives. The water-to-binder ratio was kept constant for all the concretes. The additives used were metakaolin, fly ash and microsilica. The comparison of particular dosing procedures was carried out on the values of basic mechanical properties of concrete. The paper compares compressive strength and depth of penetration of water under pressure. Besides the comparsion of macro-mechanical properties, the effect of microsilica and fly ash additives on micro-mechanical properties was observed with the use of scanning electron microscopy (SEM) and nanoindentation data analysis. Nanoindentation was used to determine the thickness and strength of interfacial transition zone (ITZ) for different sequence of addition of cement, additive and aggregate. The thickness obtained by nanoindentation was further investigated by SEM EDS line scanning.

Analysis of Fire Resistance of Concrete Structural Members Based on Different Fire Models: An Illustrative Example of the Slab Panel Assessment
Authors: Benýšek Martin , Štefan Radek , Procházka Jaroslav
Published: June 2019

The paper deals with the analysis of fire resistance of concrete structural members exposed to fire based on different fire models. An illustrative example of the assessment of a slab panel is presented. Several fire models are employed in order to predict the evolution of temperature in a selected fire compartment. Some of these fire models, namely the ISO fire curve and the parametric fire curve, are implemented in an in-house MATLAB code. For the more comprehensive fire models, external scientific software tools are used, namely the CFAST software for the zone model and the FDS software for the CFD (computational fluid dynamics) model. By employing the results of the fire simulations, the fire resistance of the slab panel is assessed. It is performed by a one-way coupled numerical procedure based on a well-known heat transfer finite element model and iterative sectional mechanical analysis. The procedure is implemented in an in-house MATLAB code. It is shown that (i) the numerical procedure can be employed in connection with different fire models and (ii) the fire resistance prediction can be strongly influenced by the type of selected fire model.

Authors: Augustín Tomáš , Fillo Ľudovít , Halvonik Jaroslav
Published: June 2019

Experimental programs focused on the issues related to the flat slabs still attract the attention of the scientists around the world. At the Central Laboratories of STU in Bratislava, together 8 fragments of the flat slabs were tested, focusing on the influence of the openings on the punching resistance. The two reference specimens were without openings and the others had two symmetrically placed openings. The openings were moved from the face of the column in multiples of the effective depth (0d, 1d, 2d). For the assessment of the tests, the models introduced in the relevant standards and codes were applied. The experimental results were also used for NFEM model calibration. The paper will deal with comparison of the theoretical and experimental results as well as with non-linear analysis that was performed in the ATENA FEM program, with the goal to obtain the most realistic behaviour of the flat slabs with openings. The material properties used in the analysis were obtained from the laboratory tests.

Authors: Kocáb Dalibor , Kucharczyková Barbara
Published: June 2019

The paper describes experiments designed to determine shrinkage in three types of self-levelling floor compounds. The research was designed as a double-comparative experiment. It compared shrinkage values between the flooring compounds as well as shrinkage measured on two different types of specimens. The shrinkage measurements were supplemented by the determination of weight losses. The flooring compounds discussed herein are defined by consistency and basic hardened-state properties. The measurements show the influence of specimen size on the progress and final value of shrinkage and weight losses.
Cracking and Failure Mode of the Self-Stressed Members with FRP Bars
Authors: Semianiuk Volha , Tur Viktar V.
Published: June 2019

Fiber reinforced polymer (FRP) bars represent a combination of the polymer binder and reinforcing fibers (glass, basalt, aramid, carbon). The main features of FRP bars are high tensile strength on the background of the relatively low elasticity modulus. To prevent development of the excessive both crack opening and deflections in the FRP reinforced concrete structures it can be effective to implement FRP reinforcement pretensioning with a limited level of created stresses. As a good option can be considered a physico-chemical method of FRP bars pretensioning based on the self-stressing concrete utilizing. In the self-stressed FRP reinforced members it is possible to obtain a considerable values of the early age restrained expansion strains (in comparison with steel reinforced self-stressed members because of FRP bars lower elasticity modulus), which will not disappear after air-dry shrinkage strains realization. In addition, another concern that have to be considered in the field of FRP reinforced self-stressed members is bond performance of the different FRP bars types, especially in combination with self-stressing concrete that within its expansion can provoke decompacting of the transit zone «bar-concrete». Moreover, taking into account that FRP bars is a composite material, its bond properties are strongly influenced by the types of the polymer binder, reinforcing fibers, ratio between binder and fibers, bar coating. Presented studies is consisted in the experimental investigations of the features in the crack development and depended on it occurred failure mode of the self-stressed members reinforced by the different types of FRP bars.
Examining the Influence of the Shape, Size, and Type of Test Specimens on the Value of Young's Modulus in Lightweight Concrete
Authors: Kocáb Dalibor , Daněk Petr , Žítt Petr , Tichý Aleš , Alexa Martin
Published: June 2019

The paper discusses the results of an experiment that focused on measuring Young's modulus in compression using several different specimens. They were made from lightweight concrete with porous aggregate and differed in shape (cylinder × prism), type (casting × core drilling), and size. Each type category counted a minimum of 6 specimens. The determination of Young's modulus was supplemented by a measurement of the dynamic modulus of elasticity determined by the ultrasonic pulse velocity test. The experiment was concluded by a statistical analysis of the measured values, which focused on the influence of each specimen variety on the value of the elastic modulus.

Published: June 2019

The paper compares the sulphate ion attack resistance in several mixtures of high-performance concrete. The corrosion tests were not performed with the actual concretes, but with model mortars derived from them. The resistance was compared by means of a comparative, specifically double-comparative, methodology. The paper devotes much attention to describing this method, deriving the model mortars, and choosing the correct specimens and parameters to be observed. All important test results, which confirm the effectiveness of the method, are listed. The resistance of each mortar was identified with sufficient accuracy.
Masked presentations of dissociative disorder among Sri Lankan adolescents

Published: June 2019

Dissociation could occur in adolescence in response to traumatic life experiences disrupting essential areas of psychological functioning. We report three complex presentations of dissociation in adolescents in Sri Lanka. A 16-year-old girl presented with poor sleep, overtalkativeness and euphoric mood after her father had left home a day before. During the war, a 14-year-old boy was brought to hospital as he was speaking in Tamil and mentioning the names of terrorist leaders. Later it was found that he is from a Sinhalese family and had experienced violence at home. A 16-year-old boy presented with irritability, disinhibition and regressed behaviour. A detailed assessment revealed an underlying depressive state in the context of family conflicts. All the above patients presented with features suggestive of mania, misleading clinicians and leading to unsuccessful treatment strategies. Therefore, in-depth psychosocial assessment is needed to diagnose dissociation in adolescents and to plan evidence-based treatment.

BackgroundThe internet is widely used as a source of health information, and the negative effects of this practice is well documented. Cyberchondria, the unfounded escalation of concerns about common symptoms based on review of online information has been identified as a major concern. This area has not been studied in Sri Lanka. AimsWe studied the prevalence, nature and effects of cyberchondria among outpatients in Sri Lanka. MethodsData was gathered from 300 outpatients, 150 patients each attending a government and private hospital in Western province using a self-administered questionnaire. ResultsOut of 300 participants 178 were female and the average age was 42 years. Only 24% of the participants used the internet as an information source on health related issues. The prevalence of cyberchondria was 16.3% in our study population. Cyberchondria was significantly more common among outpatients of the private hospital. A majority of patients who made a self-diagnosis using online information had made an incorrect diagnosis. One third of internet users felt anxious after searching about their symptoms and 34% sought further medical advice following internet use. Conclusions The possible negative effects of online health information is a concern in Sri Lanka. Further studies and public education regarding this area in Sri Lanka are required.

The Ouellet-Robert Entomological Collection: new electronic resources and perspectives
Authors: Favret Colin , Normandin Étienne , Cloutier Louise
Published: June 2019

The Ouellet-Robert Entomological Collection (Université de Montréal, Montréal, Québec, Canada) is one of the largest and most important university collections in Canada. Although officially dedicated in 1984, much of the material in the collection dates to the 1930s and 1940s work of the Clerics of Saint Viator, Joseph Ouellet and Adrien Robert. In order to establish curatorial priorities, a collection profile was conducted grading eight criteria on a scale of 1–4, the most important being the conservation status of the specimens. A taxonomic inventory of the collection was also conducted, including the number of pinned specimens and alcohol vials, as well as a brief geographic description: whether or not at least one specimen of each species was collected in Québec or in North America. Finally, the specimen metadata for Odonata, Ephemeroptera, and Trichoptera were digitised. The inventory and specimen data can be downloaded at Canadensys.net. The collection houses approximately 1.5 million specimens, of which one-third are pinned, representing 20 000 species. Half of those species are recorded from Québec. The inventory and profile will be updated and the specimen database grown as portions of the collection are re-curated by personnel and volunteers, including the student-run organisation, “Club QMOR”.
Delayed diagnosed atypical case of Andersen-Tawil syndrome
Authors: Burakgazi Ahmet Z.
Published: June 2019

Andersen-Tawil syndrome (ATS) is characterized by a triad of periodic paralysis, cardiac arrhythmias and distinctive dysmorphic features. Due to its rarity and high degree of clinical and phenotypic variability, a diagnosis of ATS can be very perplexing and challenging. Herein, an atypical case of ATS with a complicated presentation that caused an approximately 11-year delay in diagnosis is reported. The patient made a full recovery with acetazolamide after the diagnosis. The case and its management are presented with an updated literature review.

Treatment of Obesity with Western Medicine and Traditional Medicine: Based on PubMed and Science Direct Databases
Authors: Korio Gabriella
Published: June 2019

The objective of this review was to collect the current published research on obesity and gain insight into the association of treatment based on a global aspect. The first section of the review will cover the treatment of obesity based on a Western medicine lens. The second section of the review will cover the treatment through a traditional approach based from different regions of the world (not including China). The third section of the review will cover treatment through a traditional Chinese medicine approach. The most commonly used electronic databases were used to search for articles related to obesity. The articles gathered consist of a broad spectrum from various parts of the world. Terms used in the search bar consisted of “obesity”, “BMI”, “acupuncture”, “traditional Chinese medicine”, etc. The majority of findings were collected from treatment based on both a western medicine and traditional Chinese medicine approach. The published literature collected is predominantly sourced from the online journal databases PubMed and Science Direct. Obesity is an ever-growing issue throughout society today. Different methods have shown effective results in treating this disease. It is crucial to continue exploring different treatment methods in hopes to solve this major public health issue.

Published: June 2019

Abstract. This paper presents a new data set of vertical column densities of the water vapour isotopologues H2O and HDO retrieved from short-wave infrared (2.3 μm) reflectance measurements by the Tropospheric Monitoring Instrument (TROPOMI) aboard the Sentinel-5 Precursor satellite. TROPOMI features daily global coverage with a spatial resolution of up to 7 km × 7 km. The retrieval utilises a profile-scaling approach. The forward model neglects scattering, thus strict cloud filtering is necessary. For validation, recent ground-based water vapour isotopologue measurements by the Total Carbon Column Observing Network (TCCON) are employed. A comparison of TCCON δD with measurements by the project Multi-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water (MUSICA) for data prior to 2014 (where MUSICA data is available) shows a bias in TCCON δD estimates. As TCCON HDO is currently not validated, an overall correction of recent TCCON HDO data is derived based on this finding. The agreement between the corrected TCCON measurements and collocated TROPOMI observations is good with an average bias of (0.02 ± 2) · 1021 molec cm−2 in H2O and (−0.3 ± 7) · 1017 molec cm−2 in HDO, which corresponds to a bias of (−12 ± 17) ‰ in a posteriori δD. The use of the data set is demonstrated with a case study of a blocking anticyclone in northwestern Europe in July 2018 using single overpass data.
Effects of atmospheric CO2 variability of the past 800 kyr on the biomes of southeast Africa
Authors: Dupont Lydie M. , Caley Thibaut , Castañeda Isla S.
Published: June 2019

Abstract. Very little is known about the impact of atmospheric
carbon dioxide pressure (pCO2) on the shaping of biomes. The development
of pCO2 throughout the Brunhes Chron may be considered a natural
experiment to elucidate relationships between vegetation and pCO2. While
the glacial periods show low to very low values (∼220 to
∼190 ppmv, respectively), the pCO2 levels of the
interglacial periods vary from intermediate to relatively high
(∼250 to more than 270 ppmv, respectively). To study the influence
of pCO2 on the Pleistocene development of SE African vegetation, we used
the pollen record of a marine core (MD96-2048) retrieved from Delagoa Bight
south of the Limpopo River mouth in combination with stable isotopes and
geochemical proxies. Applying endmember analysis, four pollen assemblages
could be distinguished representing different biomes: heathland, mountain
forest, shrubland and woodland. We find that the vegetation of the Limpopo
River catchment and the coastal region of southern Mozambique is
influenced not only by hydroclimate but also by temperature and atmospheric
pCO2. Our results suggest that the extension of mountain forest occurred
during those parts of the glacials when pCO2 and temperatures were
moderate and that only during the colder periods when atmospheric
pCO2 was low (less than 220 ppmv) open ericaceous vegetation including
C4 sedges extended. The main development of woodlands in the area took place
after the Mid-Brunhes Event (∼430 ka) when interglacial
pCO2 levels regularly rose over 270 ppmv.
Long-term Surface Temperature (LoST) database as a complement for GCM preindustrial simulations

Published: June 2019

Abstract. Estimates of climate sensitivity from general circulation model (GCM) simulations still present a large spread despite the continued improvements in climate modeling since the 1970s. This variability is partially caused by the dependence of several long-term feedback mechanisms on the reference climate state. Indeed, state-of-the-art GCMs present a large spread of control climate states probably due to the lack of a suitable reference for constraining the climatology of preindustrial simulations. We assemble a new gridded database of long-term ground surface temperatures (LoST database) obtained from geothermal data over North America, and we explore its use as a potential reference for the evaluation of GCM preindustrial simulations. We compare the LoST database with observations from the Climate Research Unit (CRU) database, as well as with five past millennium transient climate simulations and five preindustrial control simulations from the third phase of the Paleoclimate Modelling Intercomparison Project (PMIP3) and the fifth phase of the Coupled Model Intercomparison Project (CMIP5). The database is consistent with meteorological observations as well as with both types of preindustrial simulations, which suggests that LoST temperatures can be employed as a reference to narrow down the spread of surface temperature climatologies on GCM preindustrial control and past millennium simulations.
