Evaluation of Innovation Expenditures and Patents in the Polish Industry
Authors: Zwolak Jan
Published: April 2020

The aim of the research has been to identify the elasticity of process and product innovation expenditures, the number of inventions as well as the number of patents in terms of net revenues generated from the sales of new and significantly improved products in the Polish industry over the years 2015-2017. Furthermore, a focus was also placed on the determination of the marginal and average productivity of innovation expenditures, as well as that of inventions and patents as observed in the Polish industry within the above-indicated period. The calculated marginal and average productivity values of independent variables allow for an indication of the areas of their rational management in the Polish industry. The research shows that the elasticity of inventions is greater (0.403) than the process and product innovation expenditures (0.333). On the other hand, the second power regression performed points to the fact that the elasticity of process and product innovation expenditures is higher (0.420) than the patent expenditure (0.251) within the relative increase in net revenues generated from sales of new and significantly improved products in the industry in Poland. A hypothesis has been confirmed claiming that the elasticity of patents – be it at its lowest – does increase the level of flexibility of process and product innovation expenditures in the Polish industry. A quality verification of inventions and their distinction as intellectual and legal property in the category of patents leads to the effective use of process and product innovation outlays within the relative increase in the net revenues obtained from the sale of new and significantly improved products in the industry in Poland. The conducted research reveals a new perspective on inventions and patents. Although the number of patents may show less elasticity, patents were significant in increasing the efficiency of process and product innovation expenditures effectuated within the industry in Poland over the years 2015-2017
Assessing the Intellectual Capital and Related Performance in the Teaching Process using FES models: first evidence in Italian Universities
Authors: Lucchese Manuela , Aversano Natalia , Di Carlo Ferdinando , Tartaglia Polcini Paolo
Published: April 2020

Our study provides to define two frameworks of indicators to assess both the Intellectual Capital (IC) employed in the Educational Process in the University sector and the Performance Educational Process reached. The scope is to obtain two tools for measuring, on the one hand, the level and the determinant variables of the IC that represents the input of the Educational Process. On the other hand, the level and the determinant variables of the outcome of the Educational Process. The comparison of the tools scores allows you to understand if at a high level of Educational Performance corresponds to a high level of IC trying to evaluate the ability of the IC to create value. The research questions are answered using a quantitative methodology using the FES models. We define two models to measure the IC Educational Index and Educational Performance. We construct the FES models in compliance with the previous literature on the IC and the theoretical model report of the Intellectual Capital of the Austrian Universities. To define the frameworks of indicators to assess the IC Educational Index and the Educational Performance we use, compliant to the previous literature, the SMA Indicators required by the AVA-MIUR for Italian University Sector. We collected 30 Italian public Universities. Thus, we determined and compared both the IC Educational Index and its determinants and Educational Performance Score and its determinants. Our main result is the construction of two toolboxes to assess the level of IC and the connected Performance of the Educational Process in the University sector. The findings suggest which are the indicators to improve the IC Index or the Educational Performance Score for an in-depth understanding of the value creation process.The paper is novel because it contributes to the literature examining the model to measure both the IC employed in the Educational Process and the Educational Performance. Moreover, comparing the resultant scores, we investigated the relation between input and output in the Educational value creation.
Natural Approach or Cognitive Approach. Learning or Acquiring a Foreign Language? Research Study at Centro de Lenguas de la Universidad Autónoma de Ciudad Juárez
Authors: Serrano Romero Enriqueta Claudia
Published: April 2020

There is a big dilemma among instructors teaching English as a foreign language. Competence and teaching grammar rules are the primary pedagogical concern. Competence is directly related to the ability of proper grammar use of a language. However, methodological discussions end up accepting that grammatical rules are neither sufficient nor demonstrating the acquisition of the language. Learner students may have correctly learned grammatical rules, but some studies disagree on teaching only grammar because it will not be enough for students to speak forcefully. These circumstances lead to the discussion on the English Teaching method used at the Autonomous University of Ciudad Juárez (UACJ). This study aims to answer 1.) Which of the following approaches are more suitable to teach a second language, Natural Approach vs. Cognitive Approach?  2.) As to what extent should we emphasis grammar rules on teaching a second language to obtain the most benefit? Lastly, a sizable neurolinguistics portion of information is added to help us understand how the brain responds to learning a foreign language.

Hatred of the Earth, Climate Change, and the Dreams of Post-Planetary Culture
Authors: Tabas Brad
Published: April 2020

This text examines the effects of climate change on cultural ideas regarding the colonization of space. More specifically, this paper explores the ways which the looming danger of climate catastrophe has fueled the growth of post-planetary culture: a culture that dreams of a human destiny beyond the Earth. It takes as its object both science fiction texts and non-fiction futurological pronouncements by scientists and entrepreneurs. What emerges from this study is the observation that unlike climate skeptics, post-planetarists believe that climate change is real. Yet like climate skeptics, they subordinate climate action to other priorities, putting the construction of a means of escaping this planet above climate action. But why do these post-planetarists wish to fly? Via a close reading of David Brin’s Earth, we argue that one of the key characteristics of post-planetary culture is a feeling of hatred and alienation towards the Earth. This hatred is both re-enforced by the ravages of climate change even as it contributes to this destruction by blocking post-planetarists from whole-heartedly engaging in climate action. In order to illustrate an antidote to this pathological cultural reaction to our current crisis, I present a close reading Kim Stanley Robinson’s Aurora, exploring how this text is both a critique of post-planetarism and a guide to renewing our love for the Earth.
Nichts als Katastrophen? Klimawandel als Herausforderung für die utopische Tradition
Authors: Herold Emanuel
Published: April 2020

Aktuelle klimapolitische Debatten sind von einem apokalyptischen Denken durchdrungen. Auch Bewegungen wie Fridays for Future sind davon geprägt – positive Zielsetzungen bleiben dagegen abstrakt, utopische Bilder einer nachhaltigen Gesellschaft stehen nicht im Vordergrund der öffentlichen Auseinandersetzungen. Ich möchte dafür argumentieren, dass eine Vergegenwärtigung und Fortschreibung der Tradition der literarischen Utopie Potentiale für alternative Zukunftskonstruktionen bieten. Ich möchte der Frage nachgehen, wie literarische Utopien Momente eines besseren Lebens in einer vom Klima verwandelten Zukunftswelt aufzeigen können. Dazu werde ich (1.) aktuelle literaturwissenschaftliche Diskussionen zum sogenannten „Cli-fi“-Boom betrachten. Insbesondere die zeitlichen Dimensionen des Klimawandels erweisen sich als eine beachtliche Schwelle für seine gelingende Literarisierung. Allerdings, so werde ich (2.) darlegen, gründet gerade die Wandelbarkeit literarischer Utopien auf ihrer Fähigkeit, Zeitlichkeit zu modellieren. Vor diesem Hintergrund werde ich (3.) mit Kim Stanley Robinsons New York 2140 einen aktuellen Text analysieren, der die utopische Tradition vor dem Hintergrund der aktuellen Debatten um Klimawandel und Anthropozän fortschreibt. Ich werde nachzeichnen, mit welchen Strategien es ihm gelingt, individuelle, soziale und klimatische Zeitebenen miteinander zu verknüpfen. Abschließend (4.) werde ich kurz diskutieren, weshalb eine kritische Reflexion der zeitgenössischen Dominanz apokalyptischen Denkens für aktuelle klimapolitische Debatten wichtig ist: Die Fixierung auf potentielle Verwüstungen und überambitionierte Reduktionsziele bergen die Gefahr, dass die derzeit mobilisierten Kräfte allzu schnell frustriert werden und in eine zynische Haltung umkippen.
Feature binding contributions to effect monitoring
Authors: Wirth Robert , Kunde Wilfried
Published: April 2020

Monitoring the perceptual effects of body movements is supposed to be a capacity-limited process that can interfere with processing of a concurrent task. Here we studied the contribution of feature binding to such effect monitoring interference. In three experiments, we varied the possibility of feature overlap between responses and effects in a primary task and responses in a secondary task. We show that responses in a secondary task are delayed when they partially, rather than completely, alternate or repeat features of responses/effects of a primary task. Yet, these partial feature repetition/alternation costs are small, and they occur on top of other factors that lengthen the critical effect monitoring process, such as the spatial compatibility of responses and effects in the primary task. The results thus show that feature binding contributes to, but cannot fully account for, delays in a secondary task caused by monitoring effects of a primary task.

Abstract:Background: Lymph node are located throughout the lymphatic system, they are concentrated in certain areas of the body including head and neck. Cervical lymph nodes are lymph nodes found in the neck. Of the 800 lymph nodes in the human body, 300 are in the neck. Cervical lymph nodes are subject to several different pathological conditions including tumours, infection and inflammation.Methodology: The Povidine-iodine and chlorhexidine for preoperative skin preparation in cervical lymph node biopsy procedure were used in this study and patients were asked for follow up after a week. On follow up day their wounds were checked, assessed and withdraw all stiches and complications were recorded accordingly and analysed them. It was discussed and showed that which one of Povidine-iodine and chlorhexidine is best to use for preoperative skin preparation in cervical lymph node biopsy procedures to reduce surgical site infection and economical one.Results: Out of 150 patients, 46% (69) were males and 54% (81) were females that had cervical lymphadenopathy after skin preparation by chlorhexidine antiseptic solution showed frequency of infection in total of 150 patients 16.67% (25) were infected while the other 83.33%(125) were not infected. Out of 150 patients who were underwent cervical lymphadenopathy after using povidine iodine skin preparatory antiseptic solution, 42% (63) were males and 58% (87) were females and among those frequency of infection showed 44.67% (67) were infected while the others 55.33% (83) were not.Conclusion: Preoperative scrubbing of the patient’s skin with chlorhexidine–alcohol is better than scrubbing with povidone–iodine for preventing surgical-site infection after cervical lymph node biopsy.

AbstractBackground: Obstructive lung disease (OLD) is one of the main causes of mortality and morbidity worldwide. Obstructive lung disease is the narrowing of bronchioles mainly due to excessive smooth muscle contraction. The objective of this study is to evaluate the Frequency of HIV in obstructive lung disease patients.Methodology: Samples were collected randomly, and study was completed in almost six months. 100 samples were taken with an informed consent taken from all the patients. EDTA and Clotted blood was collected for HIV ELISA and HIV screening.Results: In this study, 69% Males and 31%Females, 34% Smokers, 26% patients were Hypertensive, 10% patients were diabetic, 3% patients were diagnosed HIV positive by screening and ELISA.Conclusion: The frequency of HIV in obstructive lung disease patients in this research is not very high as compared to the previous researches, showing high frequency and relationship between HIV and obstructive lung disease patients. The reason behind low frequency is due to low sample size so by increasing the sample size we can get better understanding of frequency of HIV in obstructive lung disease patients. Another reason of insignificant results is low prevalence of HIV in Pakistan as compared to the previous researches in certain countries.

Published: April 2020

To understand drivers’ yielding behavior, field observations and semi-structured interviews were conducted. Cramer’s V and logistic regression analyses of the field observation on 1140 drivers and pedestrians demonstrated that driver gender and pedestrian age have significant relationships with the tendency to yield the right of way. Other than gender and age, road characteristics were also investigated to understand the nature of this relationship between drivers and pedestrians to a broader extent. From the interviews’ thematic analysis, four themes related to participants' thoughts about yielding behavior were obtained: "Places of Interaction," "Trust in Rules," "Factors Affecting Yielding Behavior", and "Future Solutions." Both the analysis of interviews and the observations showed that driver-pedestrian interaction is an essential factor regarding traffic safety.

Motivated by the identification of the blazar TXS 0506+056 as the first promising high-energy neutrino counterpart candidate, we search for additional neutrino blazar candidates among the Fermi–Large Area Telescope detected blazars. We investigate the multiwavelength behavior from radio to GeV gamma-rays of blazars found to be in spatial coincidence with single high-energy neutrinos and lower-energy neutrino flare candidates. In addition, we compare the average gamma-ray emission of the potential neutrino-emitting sources to the entire sample of gamma-ray blazars. We find that neutrino-emitting blazar candidates are statistically compatible with hypotheses of both a linear correlation and no correlation between neutrino and gamma-ray energy flux.
Conservation of terrestrial invertebrates: a review of IUCN and regional Red Lists for Myriapoda
Authors: Karam-Gemael Manoela , Decker Peter , Stoev Pavel , Marques Marinez I. , Chagas Jr Amazonas
Published: April 2020

Red Listing of Threatened species is recognized as the most objective approach for evaluating extinction risk of living organisms which can be applied at global or national scales. Invertebrates account for nearly 97% of all animals on the planet but are insufficiently represented in the IUCN Red Lists at both scales. To analyze the occurrence of species present in regional Red Lists, accounts of 48 different countries and regions all over the world were consulted and all data about myriapods (Myriapoda) ever assessed in Red Lists at any level assembled. Myriapod species assessments were found in eleven regional Red Lists; however, no overlap between the species included in the global IUCN Red List and the regional ones was established. This means that myriapod species considered threatened at regional level may not be eligible for international funding specific for protection of native threatened species (more than US$ 25 million were available in the last decade) as most financial instruments tend to support only threatened species included in the IUCN Red List. As the lack of financial resources may limit protection for species in risk of extinction, it is urgent to increase the possibilities of getting financial support for implementation of measures for their protection. A Red List of all Myriapoda species recorded in Red Lists at national or local (596) and global (210) scales totaling 806 species is presented. This list shows for the first time an overview of the current conservation status of Myriapoda species. Here, the urgent need of establishing a Myriapoda Specialist Group in the Species Survival Commission of IUCN is also stressed.
Social space and family reproduction among Quebec City leather workers in 1911

Published: April 2020

Cet article explore les caractéristiques de la reproduction familiale au sein du groupe socio-professionnel que forment les travailleurs du cuir dans la ville de Québec au tournant du xx e siècle. Il en examine les dimensions sociale, spatiale et familiale de manière à contextualiser les dynamiques de reproduction en période d’industrialisation. Ancrée dans une perspective d’histoire sociale, cette étude vise à outrepasser la dichotomie entre, d’un côté, les interprétations matérialistes, et, de l’autre, les interprétations culturelles des changements démographiques. Nous nous concentrons ici sur les dynamiques de l’économie familiale issues de l’enchevêtrement des expériences individuelles de travail et du vivre ensemble au quotidien ainsi que des perceptions des normes et rôles accolés aux hommes, femmes et enfants. Nous adoptons une perspective analytique qui s’appuie sur les concepts de communication communities et de réseaux familiaux multigénérationnels en examinant de manière très détaillée la distribution résidentielle et les réseaux de parenté de ces familles. Pour ce faire, nous tirons profit des microdonnées du recensement de 1911, lesquelles ont été géoréférencées à l’échelle du bâtiment et jumelées aux registres de l’état civil. Les résultats de cette micro-étude apportent un éclairage nouveau sur les comportements de fécondité et sur la complexité de l’articulation entre les modes de production et les stratégies de reproduction.
Fertility decline in the United States, 1850-1930: New evidence from complete-count datasets
Authors: Hacker J. David , Roberts Evan
Published: April 2020

De 1835 à 1935, la fécondité aux États-Unis a chuté de 7 enfants par femme à 2,1. Le dépouillement intégral du recensement américain réalisé par IPUMS pour les années 1850, 1880, 1910 et 1930 permet d’analyser très finement cette baisse. Pour cela, nous construisons des modèles inclusifs de la fécondité des couples qui prennent en compte une très large variété de facteurs économiques, sociaux, culturels et familiaux, y compris des mesures de la religiosité et de la disponibilité de membres de la famille résidant hors du ménage mais à proximité de celui-ci. Nos résultats mettent en évidence le rôle majeur dans la baisse de la fécondité joué par les pratiques et perceptions culturelles et religieuses, approchées par l’origine des parents – notamment le pays de naissance – et les choix de prénoms.
Le Hezbollah dans le rétroviseur de la guerre « civile »
Authors: de Clerck Dima , Malsagne Stéphane
Published: April 2020

De 1982 à 2020, le Hezbollah est passé du statut d’acteur parmi d’autres d’une guerre « civile » 1  destructrice (1975-1990), à celui d’acteur incontournable de la scène libanaise et régionale. Auréolé par son rôle décisif comme force de résistance à l’occupation israélienne, l’organisation s’est transformée et s’est progressivement imposée par la force de ses armes et par le jeu électoral au cours des années 2000. Si son rôle après 1990 est le mieux connu du public averti, cet article montre pourtant à quel point la Guerre du Liban fut le moment décisif pour la formation et l’affirmation du mouvement.

Published: April 2020

Cet article est le fruit d’un travail de recherche pionnier sur les relations druzo-chrétiennes présenté dans le cadre d’une thèse de doctorat en histoire soutenue en 2015. Il met en lumière les moyens mis en œuvre par Kamal Joumblatt puis par son fils Walid, leaders traditionnels de la communauté druze libanaise et porteurs par excellence du legs mémoriel de leur famille, pour tenter d’imposer leur mémoire clanique à l’ensemble de leur communauté. Cette étude permet d’aborder les enjeux d’une architecture mémorielle qui posent la question essentielle de la refondation d’une société déchirée par des dissensions internes et de rendre compte des limites de la tentative de greffe.
De l’espace public, des musulmans et des libertés…
Authors: Bistolfi Robert
Published: April 2020

Après chaque attentat islamiste, les demandes d’une régulation plus stricte de l’espace public se sont multipliées. Deux discours vont finalement dans le même sens : l’un entend délimiter autoritairement ce qui peut s’exprimer publiquement, l’autre se veut plus libéral mais définit un lieu de consensus obligé où ne seront vraiment tolérées que des expressions s’inscrivant dans la bande moyenne des sensibilités du moment. Cela tient partiellement au fait que l’espace public n’avait pas d’autonomie au départ et qu’il a d’abord été défini de l’extérieur.
Depopulation mechanism for incoherent terahertz source – THz torch – based on GaAsBi/GaAs quantum well in GaAs/AlGaAs parabolic quantum well
Authors: Karaliūnas Mindaugas , Udal Andres , Valušis Gintaras
Published: April 2020

Parabolic quantum wells (PQWs) are known as a promising candidate for a compact terahertz (THz) source. PQWs have equidistant subbands that can be designed to be separated by few meV to meet the THz frequency range. To enhance the efficiency and power of THz emission from PQWs, a new approach is proposed by employing depopulation of the lowest subbands of PQW. In this work, the theoretical analysis of an incoherent THz torch device is presented. The findings suggest that the introduction of narrower band-gap GaAsBi/GaAs rectangular quantum well within the GaAs/AlGaAs PQW can alter subbands arrangement to enable a faster depopulation mechanism exploiting LO phonon scattering. The calculated radiative power spectra show the increase of oscillator strength between the rearranged subbands of PQW due to the added GaAsBi rectangular potential. The increased intersubband radiative transition probability can lead to an efficient compact incoherent THz source – THz torch.
Volcanism and evolution of the landscapes in Cappadocia
Authors: Çiner Attila , Aydar Erkan , Sarıkaya M. Akif
Published: April 2020

Cappadocia, situated in the Central Anatolia Plateau in Turkey, is characterized by widespread volcanic rocks (lavas, ignimbrites and pyroclastic deposits) alternating with fluvio-lacustrine sediments of Miocene (around 10 million years) to Quaternary age. The evolution of the Cappadocian landscape starts with gently sloping plateaus, which are then dissected, usually along fractures of soft-unwelded ignimbrites, to form mushroom-like, cone-shaped structures known locally as ‘fairy chimneys’. We present here a brief description of the stratigraphy of the Cappadocian volcanic succession and explain types of volcanic products. Different landforms created by the erosion of the volcanic rocks are also explained. Because of the favorable engineering properties of the ignimbrites, ancient populations have carved their houses, churches and even underground cities for centuries. Today, this unique cultural and morphological heritage site, classified under UNESCO World Heritage List since 1985, is one of the most visited regions of Turkey.

Longtemps Reims n’était entré dans l’histoire qu’avec César et la guerre des Gaules. Il est vrai que, malgré une mythologie ancienne revendiquant une origine au moins aussi lointaine que celle de Rome, les témoignages archéologiques antérieurs étaient peu consistants mais surtout ignorés. L’archéologie préventive a progressivement accumulé des données attestant une occupation pouvant remonter au moins au iie s. av. J.-C. Le recensement des découvertes anciennes permet même d’imaginer des origines plus lointaines et de distinguer une évolution par grandes étapes successives qui ont abouti à la ville augustéenne et qui se matérialisent dans des interventions concrètes sur la forme urbaine. Des documents remontant à La Tène ancienne associent la naissance du site de Reims à celui de l’organisation du territoire des Rèmes. Un vaste espace, voué à une fonction indéfinie, a pu se développer très tôt sous l’égide d’un sanctuaire surplombant le site. Au iie s. av. J.-C., les occupations se multiplient au centre de la cuvette formant l’assiette de la future ville. Vers la fin de l’Indépendance, un oppidum circonscrit précisément les limites de l’agglomération qui connut un rapide développement au lendemain de la Conquête. Puis l’accession de la ville au statut de capitale de province coïncide avec une entreprise de refondation ambitieuse qui dessine une agglomération d’environ 500 ha, entourée d’une enceinte gigantesque dont le tracé semble rappeler l’ancienneté de la fondation du site, et illustre, par la même occasion, une continuité remarquable de l’implantation foncière et des tracés directeurs.

Nijmegen is the oldest city in the Netherlands. The modern name refers to its Roman origin. The history of Nijmegen during the first centuries of the Christian era mirrors events in the north-west of the Roman Empire. Around 19 BC, at the start of the third phase of conquest to the north with much military activity, the Oppidum Batavorum was founded in the centre of modern Nijmegen. Further growth of the town was cut short by increasing pressure on the local inhabitants, culminating in the Batavian Revolt of 69-70 AD, during which the Oppidum Batavorum was destroyed. A period of integration followed, resulting in the formation of the province of Germania inferior. During this period, the Batavian capital was moved westwards, to the low-lying western part of Nijmegen, where a new vicus was founded. In about 100 AD this settlement was granted municipal status and a new name (Ulpia Noviomagus), and grew into a town after the typical Roman model. After several generations of progress and prosperity, this settlement came to an abrupt end in the last quarter of the 2nd c.

Anterior cruciate ligament (ACL) rupture is an injury in young adults, triggering undesirable neuromuscular effects. A rehabilitation program is structured with exercises that aid in intensive care training, and proprioceptive training has been proposed as one of the training / rehabilitation methods in patients undergoing ACL reconstruction. Thus, this study aimed to analyze, through a systematic literature review, the effects of including proprioceptive training on different outcomes (stability / balance, proprioception, strength, functional capacity, coordination) after ACL reconstruction surgery in young adults. The search of the articles included studies in the last ten years, being a search conducted in November 2018. Searches were conducted in the electronic databases of PubMed and Science Direct with a following search methodology: (("Proprioception" [Mesh] ) OR "Proprioception" [Word Text]) AND ("Anterior Cruciate Ligament" [Mesh] OR "Anterior Cruciate Ligament Reconstruction" [Mesh] OR "Anterior Cruciate Ligament Injury" [Mesh]). Six studies were selected for the analysis and the results obtained there is insufficient scientific evidence showing the positive effects of training in proprioceptive training after ACL reconstruction in adults, in view of a shortage of studies, such as discrepancies in findings, without time of intervention and in the tests contracted in the analysis of the variables.
EFFECT OF HYBRIDIZATION ON THE MECHANICAL PROPERTIES OF POLYPROPYLENE (PP) FIBER-REINFORCED CONCRETE (FRC)

Published: April 2020

Esta pesquisa baseia-se na investigação das propriedades mecânicas do concreto reforçado com fibras (CRF) híbridas de Polipropileno (PP). São duas formas de fibras a serem investigadas: macrofibras e microfibras de PP, para tanto foram estudados 10 grupos de CRF. A premissa da pesquisa é que as duas formas de fibras de PP trabalhem conjuntamente contribuindo em estágios distintos do histórico de carregamento do material na flexão: as microfibras devido a maior dispersão na matriz atuem na interceptação de microfissuras e com as macrofibras, espera-se a contribuição no sentido de evitar a propagação da fissuração de forma a aumentar a tenacidade do material. Para tanto, foram desenvolvidos ensaios de flexão em quatro pontos em corpos de prova prismáticos (150 x 150 x 500 mm) seguindo-se a metodologia indicada pela norma Japonesa JSCE-SF4 (1984). Foram também moldados corpos de prova cilíndricos (100 x 200 mm) e submetidos a ensaios de compressão para obtenção da resistência axial e do módulo de elasticidade, bem como, a resistência à tração indireta. Os resultados mostraram que através do processo de hibridização foi possível a obtenção de CRFs com melhores resultados em termos de aumento da tenacidade, bem como das tensões residuais.

O trabalho apresenta os resultados de um experimento que teve como objetivo avaliar um possível declínio da infiltração de água em uma calçada construída com pavers. Uma calçada deste tipo de material geralmente é feita com peças justapostas e os vãos existentes entre eles são preenchidos com areia. As amostras apresentadas neste trabalho foram obtidas para três tipos de areia, relativamente ao tamanho máximo de seus grãos, sendo que a classificação foi feita por meio de peneiramento. O experimento foi realizado na cidade de Cascavel, Paraná, onde o solo é do tipo Latossolo Vermelho Distroférrico. Para os três tratamentos realizados a análise dos dados mostrou que este sistema de calçada perde grande parte da sua eficiência em um curto período de tempo
AVALIAÇÃO NUMÉRICA DA INFLUÊNCIA DO TIPO DE CARREGAMENTO NA LARGURA EFETIVA DE PONTES MISTAS DE AÇO E CONCRETO EM SEÇÃO CAIXÃO

As vigas mistas de aço e concreto apresentam melhor rigidez, resistência e ductilidade comparadas às vigas de concreto armado e de aço. Entretanto, no que diz respeito à distribuição dos esforços, as tensões na laje de concreto não são uniformes, acarretando em seções não planas após o carregamento. Visto isso, para utilizar a hipótese das seções planas de Navier-Bernoulli, surge o conceito de largura efetiva. O trabalho em questão avaliou numericamente no software Abaqus® a influência do tipo de carregamento na largura efetiva de pontes mistas de aço e concreto em seção caixão. Mais especificamente, realizou-se uma análise paramétrica variando a geometria da seção mista e o vão longitudinal, para situações de carregamento distribuído uniformemente no tabuleiro e pontuais no meio do vão. A largura efetiva mostrou-se proporcional à altura da laje e ao comprimento de vão longitudinal. Quanto à forma de aplicação do carregamento, os modelos com carregamento distribuído apresentaram valores de largura efetiva superiores aos com carregamento pontual.

In the present paper (1-x)Pb (Zr1-yTiy)O3 – xPb (Mn1/3Sb2/3)O3 – z at%E system, with E = Pr3+, Nd5+ and Gd3+ where x = 0.12; y = 0.48; z = 0 and 0.02 ceramic synthesized by solid state reaction technique is analysed. The investigation aims studying of the effect of dopants on the dielectric and piezoelectric properties of such piezoelectric ceramic. The prepared powders have been uniaxially pressed into discs with diameter of 10 – 12 mm and thickness of 1.2 mm. Sintering has been carried out in air atmosphere at temperatures of 1150°C and 1200°C, respectively, for 2 hours each, followed by a controlled cooling at a rate of 200°C /h. The piezoelectric properties have been investigated after a suitable preparation, including polishing, metallization. The structure of the samples has been determined by X-ray diffractometry (XRD), while the morphology and grains size have been investigated by the scanning electron microscopy (SEM). The piezoelectric properties have been studied by the resonance - antiresonance method. XRD analysis reveals a perovskite tetragonal structure and, as expected for ceramic materials, SEM analysis indicates that the average grain size increases as sintering temperature increases. The dielectric and piezoelectric properties have been determined measuring the ceramic discs, and properties, as dielectric permittivity (εr), dielectric loss (tg δ), and the electromechanical coupling factor (kp) have been obtained. The acquired results indicate a significant effect of the dopants on the dielectric and piezoelectric properties of such materials.

Authors: Alhawat Musab , Khan Amir , Ashour Ashraf
Published: April 2020

The impact-echo method is commonly used for detection of flaws in concrete elements based on the shift in the thickness frequency of a plate-like member. However, there is a need to develop this efficient technique for other applications. This paper investigates the feasibility of using the impact echo-method for identifying corrosion of steel reinforcement in concrete structures. For this purpose, 180 reinforced concrete cubes were cast and tested. The main parameters studied were the amount of recycled aggregate (i.e. 0%, 25%, 50% and 100%), nanosilica (1.5% and 3%) and the steel bar diameter (12 and 20mm). Different levels of corrosion were electrochemically induced by applying impressed voltage technique for 2, 5, 10 and 15 days. The impact-echo results were correlated against the actual corrosion levels obtained by the mass loss method. The experimental results showed that the response of impact echo in terms of frequency peaks is found to be sensitive to the high and moderate levels of corrosion. However, no clear trend was observed at the initial stage of corrosion. It is demonstrated that the impact-echo testing can be effectively used to qualitatively detect the damage caused by corrosion phenomenon in reinforced concrete structures.
