MODERN ASPECTS OF MULTIFOCAL INTRAOCULAR CORRECTION: A REVIEW
Authors: Morozova T. A. , Pokrovskiy D. F. , Medvedev I. B. , Kerimov T. Z.
Published: September 2017

During the last decade multifocal intraocular lenses (IOL) became widely used in cataract surgery and proved to be effective in recovery of visual functions. Lots of clinical studies with different multifocal IOL models showed high effectiveness of multifocal correction to achieve good visual quality for far, intermediate, and near distances. Uncorrected visual acuity at a distance is equal to multifocal and monofocal correction, while uncorrected near vision is significantly better with multifocal IOLs. Additional segment position in asymmetric multifocal IOL models did not significantly influence on visual acuity. Multiple multifocal IOL designs (bifocal, trifocal) and ADD power level provide different functional results for near and intermediate distances which allows to select the specific IOL model depending on the patient`s needs. The review covers the following aspects of multifocal intraocular correction: update for classification of multifocal IOLs, visual acuity (functional results) at different distances after multifocal IOL implantation, comparison of clinical results with different multifocal IOL designs and add power levels, influence of add segment position in asymmetric multifocal IOLs on visual quality, comparison between multifocal and monofocal correction.
What’s in a name? A discussion of what medical students and junior doctors call their senior colleagues, and why it matters
Authors: Lefroy Janet , Bartlett Maggie , Gay Simon , Hawarden Ashley , Kinston Ruth
Published: September 2017

This article was migrated. The article was marked as recommended. How should a medical student address their clinical tutor?Sociolinguistic ideas such as politeness theory tell us that the choice of formal or informal terms of address is determined by the positions of those communicating on two axes; relative status and degree of intimacy. This positioning is influenced by the interaction of personal characteristics of the individuals involved, but there are cross-cultural variations to these rules which are also changing as the world changes. The purpose of the communication will also influence terms of address.There is evidence that reducing social distance within teams improves team-working and that the perception of hierarchy prevents medical students asking for help. Such evidence forces us to take an honest look at how we train our junior colleagues to address us.Students may discover that the etiquette of the medical school classroom differs from that of the clinical placement and find themselves uncertain about how to address their colleagues appropriately. We suggest that it may be helpful in such a quandary to 'mind the gap' rather than ignoring it or trying to close it by imposing a blanket rule on it.We conclude by calling for sociological study with healthcare professionals and their students to discover whether formal or informal forms of address help or hinder aspects of learning and clinical teamwork.

Published: September 2017

In this article, the authors defined the procedure for maintaining the material and technical base of medical centers providing high-tech assistance (especially, transplant care) to Russian citizens. The current regulatory and methodological base determining the procedure for repairs of fixed assets is evaluated, the main issues of capital repair planning in budgetary medical centers providing high-tech medical care are considered. The innovations introduced at the present time into the legislation determining the procedure for capital repairs are defined; the applicable concepts and scope of regulation are disclosed; the procedure for the implementation of major repairs in accordance with the current regulations is considered; the key issues that make it difficult to start capital repairs of the premises in budgetary medical centers providing high-tech medical care to Russian citizens are identified. Administrative and financial discipline while ensuring the working conditions of the material and technical base has been strengthened. Considerable attention should be paid to the medium-term planning of works, preparation of technical documentation, and procurement of funds for preparatory works. Whereas it is necessary to coordinate such decisions with the Ministry of Healthcare of Russia and other governmental institutions in Russia the timing of the implementation of such projects has significantly increased.

Published: September 2017

Aim. The study was aimed to assess the prevalence and risk factors of hypertension in cardiac recipients.

Materials and methods. End-stage heart failure patients who received cardiac transplant between 01.01.2013 and 31.12.2016 in V.I. Shumakov Federal Research Center of Transplantology and Artificial Organs (Moscow) and survived 3 months after surgery were included and followed up for 999.4 ± 774.3 (108–1587) days. Young patients (<18 y/o) and patients after repeated (n = 18) or multi-organ transplantation (n = 3) were excluded.

Results.353 cardiac recipients aged 45.6 ± 1.6 years (18.1% females and 81.9% males) were enrolled into the study. Hypertension was prevalent in 17.6, 42.8, 62.3 and 71.4%, respectively, before, in 3 months, in 1 year, and 3+ years after the transplantation. The study revealed significant relationship between post-transplant hypertension incidence and pre-op body mass index (р = 0.026), serum creatinine (р < 0.001), preexisting hypertension (RR = 1.36, р = 0.022) and renal failure, as well as donor heart posterior wall thickness (р = 0.034), post-transplant dialysis (RR = 1.85, р < 0.001), and antibody mediated rejection episodes (RR = 1.7, р = 0.001). Uncontrolled hypertension in cardiac recipients was related to poor compliance and new-onset post-transplant renal failure.

Conclusion. Hypertension is highly prevalent among our population of cardiac recipients. The combination of various etiologic mechanisms, multiplex therapy and subjective factors calls for the careful individual patient management.
The Effect Tourism Development on Mitigating Urban-Rural Income Inequality: A Comparison of Differences among the Eastern, Central, and Western Regions of China
Authors:   The Tourism Sciences Society Of Korea, Kim Joon-Ho
Published: September 2017

This study investigates the effect of tourism development on urban-rural income inequality in China, a nation having fast economic growth and intense income disparity. While always remaining conscious of regional disparities of economic growth, this study examines the differences in the magnitude of effect tourism development has on mitigating urban-rural income inequality among the Eastern, the Central, and the Western regions of China. The sample period spans from 1994 to 2014, and the final sample consists of 30 provinces with 424 province-year observations. The results of this analysis demonstrate that tourism development has a decreasing effect on urban-rural income inequality. Moreover, the effect of tourism development on mitigating urban-rural income inequality is stronger throughout inland regions than it is in coastal regions. The results further imply that tourism contributes to improving economic conditions in rural areas as a result of spillover effects into related industries. This is especially true throughout inland regions.

Potential for domestic biogas as household energy supply in South Africa
Authors: Msibi Sunset S. , Kornelius Gerrit
Published: September 2017

Biogas is a clean and renewable form of energy accessible to low-income households through anaerobic digestion of readily available organic waste. The objectives of this desktop study were to investigate the feasibility of biogas use for substitution of presently used solid fuels in rural and peri-urban households, the subsequent health co-benefits, and the constraints to adoption of domestic biogas technology in South Africa. The energy demand of low-income South African households for cooking with fuelwood was found to be 27 MJ/day and the total energy demand 68 MJ/day. This is equivalent to 2 500 L/day/household of biogas for cooking and 6 250 L/day/household of biogas for complete substitution of conventional domestic fuels. Complete substitution of fuelwood used for cooking and household fuelwood use with biogas can result in the avoidance of 43% and 85.4% respectively of total disability adjusted life-years lost (702 790) and mortalities (22 365) from indoor smoke as a consequence of solid fuel use. Approximately 625 000 households in South Africa can potentially benefit from bio-digester fed with cattle and pig waste, on the basis of livestock numbers. It is infeasible to operate a domestic bio-digester fed solely with human waste, chicken waste and food waste because of insufficient feedstock. Non-sewered households with access to on- and off-site water supply generate sufficient greywater for feeding a domestic bio-digester for cooking purposes. This is, therefore, recommended over the use of drinking water.
Dezentral kooperierende sensorbasierende Subsysteme

Published: September 2017

Industrie 4.0 ist einer der Bausteine der Hightechstrategie der Bundesregierung [1]. Das Förderprojekt Dezentral kooperierende sensorbasierende Subsysteme für Industrie 4.0-Produktionsanlagen (DnSPro) adressiert eine Reihe von Aspekten, die für die Etablierung derartiger Systeme erforderlich sind. Um beispielsweise die häufig geforderte dynamische Produktionsanpassung zu ermöglichen, ist eine Abkehr vom aktuell vorherrschenden zentralisierten Automatisierungskonzept erforderlich. Denn dieser durch die Automatisierungspyramide charakterisierte Ansatz verhindert die notwendige Kooperation zwischen Anlagenkomponenten des Produktionsprozesses und Teilsystemen anderer Bereiche der Wertschöpfungskette. Neben der konzeptionellen Hierarchisierung stellt hierbei das Fehlen einer einheitlichen Infrastruktur zur Kooperation ein Kernproblem dar. Der Beitrag zeigt am Beispiel einer Getränkeabfüllanlage, wie mit Hilfe des DnSPro-Ansatzes der Informationsdurchgriff von der Planungs- bis zur Feldgeräteebene realisiert werden kann. Dafür werden Subsysteme definiert und konzipiert, die Teilabläufe autark integrieren. Die Integration dieser Module erfolgt über standardisierte, selbst­beschreibende Protokolle wie OPC UA.

Published: September 2017

Die zunehmende Produktvielfalt und die Verkürzung der Produktlebenszyklen erfordern eine schnelle und kostengünstige Rekonfiguration bestehender Produktionssysteme. Dafür ist ein aktuelles digitales Modell der bestehenden Fertigungszelle, ein digitaler Zwilling, eine geeignete Lösung. Der digitale Zwilling verringert die Kosten und verkürzt die Umrüstzeiten durch virtuelle Planung und Simulation – basierend auf dem aktuellen Zustand der realen Produktionsanlage und durch eine frühzeitige Erkennung von Konstruktions- oder Prozessablauffehlern in der Produktionsanlage. Voraussetzung ist allerdings, dass ein aktuelles (virtuelles) Anlagenmodell von den mechatronischen Bestandteilen der realen Anlage während der verschiedenen Phasen ihres Lebenszyklus existiert. Im Beitrag wird die domänenübergreifende, mechatro­nische Datenstruktur virtueller Fertigungszellen in der Automobilindustrie diskutiert. Es wird eine systematische Ankerpunktmethode vorgestellt, mit Hilfe derer sich die Abweichungen zwischen den virtuellen Modellen und der Realität ermitteln lassen. Basierend darauf wird eine regelbasierte Konsistenzprüfung zur durchgängigen, domänenübergreifenden Synchronisierung der aktuellen mechatronischen Ressourcen­komponenten der Produktionssysteme mit deren virtuellem Anlagemodell vorgestellt.

The Problem of Classification when the Data are Non-precise
Authors: Alvo Mayer , Théberge François
Published: September 2017

Non-precise data arise in a natural way in several contexts. For example, the water level of a river does not usually consist of a single number as can be seen from the intensity of the wetness as a function of depth of a survey rod. The temperature of a room varies as a function of distance from a reference point. The color intensities associated with a pixel which describe observations from remote sensing are non-precise numbers because they vary as a function of the reflection from the sun. In these examples, it is the imprecision of the observation itself that is of interest rather than the uncertainty due to statistical variation. Even in the absence of stochastic error, there would still be an imprecision in the measurement. Viertl (1997) developed the subject of statistical inference for such non-precise data and associated it very closely to fuzzy set theory. Precise data can be described by an indicator function whereas non-precise data is described by characterizing functions. In this article, we first review the notation and then consider the problems of classification for non-precise data.

Conditional versus Marginal Covariance Representation for Linear and Nonlinear Models
Authors: Pinheiro José C.
Published: September 2017

Grouped data, such as repeated measures and longitudinal data, are increasingly collected in different areas of application, as varied as clinical trials, epidemiological studies, and educational testing. It is often of interest, for these data, to explore possible relationships between one or more response variables and available covariates. Because of the within-group correlation typically present with this type of data, special regression models that allow the joint estimation of mean and covariance parameters need to be used. Two main approaches have been proposed to represent the covariance structure of the data with these models: (i) via the use of random effects, the so-called conditional model and (ii) through direct representation of the covariance structure of the responses, known as the marginal approach. Here we discuss and compare these two approaches in the context of linear and non-linear regression models with additive Gaussian errors, using a real data example to motivate and illustrate the discussion.
Asymmetric Loss Functions and Sample Size Determination: A Bayesian Approach
Authors: Stüger Hans Peter
Published: September 2017

In designing monitoring systems for public health tasks it can be important to give different weights to the cases of under- and overestimation of a binomial parameter. We show how asymmetric loss functions can be used for this aim. Bayesian interval-based approaches can be combined with these loss functions and with prior knowledge about diagnostic classification errors to determine optimal sample sizes.

Development methodology for a pulsation damper of gas control valves
Authors: Kryuchkov Alexander , Balyaba Maxim , Ermilov Mikhail , Shabanov Konstantin
Published: September 2017

The background for the proposed methodology is based on the principle of stage throttling with simultaneous equalizing and stabilizing the outflow, as well as elimination of gas-dynamic self-oscillating modes of the control valve. Having conducted an analysis of suppression and dampening means and according to established patterns of occurrence of self-oscillations we have suggested an integrated pulsations damper performing the following functions: elimination of gas-dynamic self-oscillations, reducing pressure pulsations in the source by reducing pressure drop, stage throttling with a reduced flow rate and outflow stabilization. A distinctive feature of our methodology is combining experimental dependencies with numerical simulation of natural modes and gas-dynamic processes taking place in the control valve and pressure pulsation damper. As initial data for designing the damper we have set its desired efficiency while ensuring specified operating modes of the gas distribution station and specified restrictions on dimensions and hydraulic resistance. The methodology allows for a significant reduction of broadband pressure pulsations and vibration by the damper due to the rational and maximum permissible distribution of pressure differences in the control valve and damper under operating conditions in which the total vibrational power of the control valve and damper is maintained close to the minimum.
What is the Best Way to Develop Information Literacy and Academic Skills of First Year Health Science Students? A Systematic Review
Authors: Munn Joanne , Small Jann
Published: September 2017

Abstract

Objective – This systematic review sought to identify evidence for best practice to support the development of information literacy and academic skills of first year undergraduate health science students.

Methods – A range of electronic databases were searched and hand searches conducted. Initial results were screened using explicit inclusion and exclusion criteria to identify 53 relevant articles. Data on study design, student cohort, support strategy, and learning outcomes were extracted from each article. Quality of individual studies was considered and described narratively. Articles were classified and findings synthesized according to the mode of delivery of the intervention (Embedded, Integrated, or Adjunct) and classification of the study’s learning evaluation outcome (Organizational change, Behaviour, Learning, or Reaction).

Results – Studies included in this review provide information on academic skills and information literacy support strategies offered to over 12,000 first year health science students. Courses targeted were varied but most commonly involved nursing, followed by psychology. Embedded strategies were adopted in 21 studies with Integrated and Adjunct strategies covered in 14 and 16 studies respectively. Across all modes of delivery, intervention formats included face-to-face, peer mentoring, online, and print based approaches, either solely or in combination. Most studies provided some outcomes at a level higher than student reaction to the intervention. Overall, irrespective of mode of delivery, positive learning outcomes were generally reported. Typically, findings of individual studies were confounded by the absence of suitable control groups, students self-selecting support and analysis of outcomes not accounting for these issues. As a result, there is very little unbiased, evaluative evidence for the best approach to supporting students. Nonetheless, our findings did identify poor student uptake of strategies when they are not interwoven into the curriculum, even when students were encouraged to attend on the basis that they had been identified at academic risk.

Conclusions – The majority of studies included have reported positive learning outcomes following the implementation of academic skills and information literacy support strategies, irrespective of their mode of delivery (Embedded, Integrated, or Adjunct). Clear, rigorous evidence that embedded strategies offer superior learning outcomes compared to other delivery modes is lacking. However, because of poor student uptake of strategies offered outside curricula, embedded modes of academic and information literacy support are recommended for first year health science courses.
Ethical Culture, Employee Intention to Stay and Employee Productivity in the Rivers State Civil Service
Authors: Sylva Waribugo , Comfort T. Dan-Jumbo
Published: September 2017

The study investigated the relationship between ethical culture and employee productivity in the Rivers State Civil Service. Also, the moderating effect of intention to stay on the relationship between the variables was examined. A sample of 321 was determined using Krejcie and Morgan sample size table from a population of 1905 Civil Servants from five top ministries in the Rivers State Civil Service. Data for the study was obtained through the utilization of a self-administered and structured questionnaire. The Spearman’s Rank Order Correlation Coefficient was used in analyzing the data with the aid of the Statistical Package for Social Sciences version 21. The results indicated moderate and positive correlations among the dimensions of ethical culture and employee productivity. Also, employee’s intention to stay slightly moderated the relationship between the two variables. However, the moderating role was not significant enough to reject the null hypothesis. This means that positive ethical culture enhances employee productivity in the Civil Service and hence should be encouraged.
Co-Creation of the Tourist Experience via Internet: Towards Exploring a New Practice
Authors: Berrada Mohamed
Published: September 2017

The purpose of this article is to explore the potential value added to the concept of value co-creation applied to the tourism sector and to investigate how tourists can conceive their participation through the Internet in the design of their trip with tourist producers. To do so, a survey was conducted on tourists in Morocco who have never used this practice which still does not exist locally. The objective behind this choice is to explore whether this new approach will raise the interest of the tourists and be accepted as an innovative way to live differently the tourist experience. The results of the descriptive analysis showed that Moroccan tourists – by using the Internet – think they can create value by being involved in the process which makes them satisfied. It would be stimulating as a future research to test tourists’ satisfaction after living an experience they really co-created. After all, co-creation is still a new concept in tourism that will be developed through further research and become a real trend. Especially tourists are currently looking for meaning, support, interaction, involvement, participation, authenticity, personalization of offers and unique experience. This article opens up new paths of research and allows tourist producers to know the future trends in this sector.

Authors: Huang Fan , Wang Mingjiu , Li Zhiyong
Published: September 2017

In order to create new forage variety, caucasian clover (Trifolium ambiguum Bieb.) with strong tolerance to drought and cold introduced from New Zealand as the female parent was hybridized with a white clover (T. repens L.) collected from northeast China, which has strong nitrogen fixation capacity. Hybrid embryos of caucasian clover×white clover were successfully raised using embryo rescue. 13.8% of these embryos grew to maturity. The successfully grown plants were transferred to sterilized vermiculite after 5-6 weeks and then to field after 3-4 months. The hybrid plant showed intermediate morphological features and a chromosomal number of 2n=5X=40. In order to obtain more plants for backcross, a tissue culture system was established for the hybrids, using MS+0.1mg l-1 2, 4-D+2mg l-1 6-BA, MS +0.5mg l-1 NAA+1mg l-1 6-BA+1mg l-1 KT and 1/2MS as the medium for bud-induction, differentiation and root-induction respectively. 80% of the cultured plantlets survived these growing conditions. Hybridity of the plant was also confirmed by ISSR markers using 16 primers.
In vitro callus induction and regeneration of multiple shoots through callus derived from leaf and epicotyl explants in pigeon pea (Cajanus cajan L.)
Authors: Thangella Padmavathi A.V. , Fakrudin B.
Published: September 2017

An efficient in vitro protocol was developed for callus induction, high frequency plant regeneration through callus cultures derived from cotyledonary leaf and epicotyl explants, rooting of shoots derived from callus and establishment onto the natural conditions in two cultivars of pigeon pea; ICPL 87119 and ICPL 8863. Cotyledonary leaf and epicotyl explants were tested for callus induction across 48 different combinations and concentrations of auxins and cytokinins in MS medium, wherein, higher doses of auxins (15 mg/1 NAA) in combination with lower doses of cytokinins (0.5 mg/l kinetin) induced regenerable callus from leaf explants while lower doses of auxins (0.2 mg/1 NAA) in combination with higher doses of cytokinins (8 mg/1 kinetin) induced regenerable callus from epicotyl explants in both the genotypes. Plantlet regeneration from leaf and epicotyl derived callus was optimized at 0.05 mg/l TDZ in both genotypes. Rooting was optimized on ½ MS + 0.5 mg/1 IBA media in both genotypes. Well-rooted plants were acclimatized and established successfully into natural conditions in potting mixture-containing soil: FYM in 1:1 ratio resulting in 48.01 per cent survivability. Regenerated plants were uniform morphologically with normal leaf shape and growth. This protocol finds its significance in rapid multiplication of transgenic plants.

Authors: Abohassan R. A. , Abusuwar A. O.
Published: September 2017

Different concentrations of Moringa leaf extract were used to evaluate their effects on three leguminous crops (Alfalfa and Clitoria as forage crops and Mung bean as grain legume) Three independent experiments were carried out at King Abdulaziz University Experimental Station in Makkah province during 2015 and 2016. Treatments consisted of four concentrations of Moringa leaf extract (C1=1ml of juice+10 ml of distilled water, C2=1ml of juice+20ml of distilled water, C3=1ml of juice+30 ml of distilled water and C4=1ml of juice+40 ml of distilled water) and only distilled water as control. Results showed that the higher concentration C1 contained the highest concentrations of inorganic elements and growth hormones compared to the other concentrations. Thisæ in turnæ was reflected in significantly higher growth and forage yields of both alfalfa and clitoria and significantly higher growth and grain yield of mung bean. The highest concentration C1 increased number of pods, pod dry weight, seed dry weight, and shelling out turn of mung bean compared to the control in year 2015 by 85, 60, 47 and 92%, respectively. Corresponding increments in 2016 for the same characters were 40, 47, 27 and 94%, respectively.

Published: September 2017

A total of 2,456 germplasm accessions of pigeonpea (Cajanus cajan) and its wild spp. having essential geo-coordinates (latitude and longitude)/locality information were analysed for spatial and diversity distribution through GIS tools. Analysis of passport data revealed that maximum number of germplasm accessions are collected from the states of Madhya Pradesh (438 accessions) followed by Jharkhand (387), Andhra Pradesh (326), Telangana (253), Bihar (249), Gujarat (230), Uttar Pradesh (188) and Maharashtra (178). India being the centre of origin and diversity of this crop, collecting resulted in augmentation of 86 landraces from 14 states. Among wild relatives of pigeonpea, only Cajanus scarabaeoides (46) and C. cajanifolius (6) were augmented. GIS mapping of 107 selected trait-specific germplasm (with regard to eight important morpho-agronomic traits) identified few areas – Akola (Maharashtra) for pod bearing length; Srikakulam (Andhra Pradesh) for bold seed; and Banaskantha (Gujarat) for high pod number. Unexplored and underexplored areas as well as crop wild relatives belonging to genepool one and two are identified for future collection.

A field experiment was conducted at Research farm, BCKV, West Bengal during rabi 2010-11 and 2011-12 to evaluate the effect of irrigation and mulch on growth, nodulation, yield and water use efficiency of chickpea (Cicer arietinum L.). Chickpea irrigated at IW/CPE of 0.6 showed 7.14% and 23.53% higher seed yield compared to IW/CPE of 0.4 (0.98 t/ha) and Rainfed (0.85 t/ha), respectively and was significantly superior. Maximum seed yield of about 1.01 t/ha under the treatment receiving black polythene mulch, which was about 3.59%, 7.45% and 9.78% higher over the treatments receiving straw @ 5 t/ha, water hyacinth @ 5 t/ha and no mulch, respectively. Straw mulch @ 5 t/ha performed best regarding nodule dry weight and number per plant. Water use efficiency was highest with rainfed treatment and treatment receiving black polythene. Irrigation applied at IW/CPE of 0.6 maintained its superiority with highest net return, B:C, production and economic efficiency. Among mulches, highest return, B:C and efficiencies were recorded with the application of black polythene.

Partindo da ideia de que é possível se pensar a transversalidade em educação, em que não haja solidão nem isolamento em áreas distintas - modelo disciplinar, em que projetos façam mais do que funcionar em parcerias de professores - modelo interdisciplinar, em que o conhecimento seja mais do que um tema que atravessa as várias disciplinas separadas - modelo transversal dos PCNs, em que até a seriação possa ser questionada, apresentamos neste trabalho experiências que levaram alunos à experimentação com imagens a partir da leitura da obra Morte e Vida Severina, de João Cabral de Melo Neto, também feita nas aulas de Geografia do Ensino Fundamental. Mostramos trabalhos com imagens em três tempos, disciplinar, interdisciplinar e transversal, defendendo este último como aquele que possibilita o envolvimento e permite a criação em projetos educacionais, nos dias de hoje. Nesse projeto destacou-se uma ênfase na organização do conhecimento que envolve o tempo, espaço e sociedade, que se movimentam para além das definições em si. A tecnologia, como instrumento de análise, de conhecimento e de experimentação, leva a possíveis deslocamentos e a um transbordamento dos sentidos. Afinal, o que era esse sertão, a migração, o mandacaru, a caatinga? Quem foi Lampião? Propomos, de acordo com a filosofia de Gilles Deleuze e Félix Guattari, abandonar verticalismos e horizontalismos, em favor de fluxos que possam tomar qualquer direção, sem hierarquia definida de antemão, rizomáticos; em favor da pulverização, da multiplicidade, de interesses e da diferença; defendendo a imagem como possibilidade de policompreensões infinitas na educação.
O folclore e a escrita da História: a cultura popular como fonte
Authors: Néia Vitor Hugo Silva
Published: September 2017

Desde o século XIX, o folclore tem sido objeto de controvérsia nas Ciências Humanas. Parte disso se deve à posição de que suas manifestações constituem vestígios de tradições cristalizadas, passadas de geração a geração, que se confundem em um passado pouco apreensível pelo tempo histórico e estão imunes a transformações. Considerando a tradicionalidade e a longa duração que caracterizam essas manifestações da cultura popular, este artigo traça um panorama do desenvolvimento dos estudos folclóricos, em especial a partir da Folklore Society britânica, a fim de propor abordagens contemporâneas sobre o uso de suas fontes e a recuperação de sua importância para a escrita da História. Com isso, espera-se iluminar alguns aspectos relevantes ao trabalho do historiador, entendendo que o folclore se expressa e se transforma em consonância com as dinâmicas sociais e históricas.
Texto historiográfico como “discurso de justificação”: Cecília Westphalen e a construção de um lugar para si
Authors: Machado Daiane Vaiz
Published: September 2017

Fazemos, neste artigo, a leitura de textos de história da historiografia como “discurso de justificação”. Os textos objetos foram produzidos entre 1983 e 1984 pela historiadora Cecília Westphalen (1927-2004) e promovem um balanço sobre a historiografia paranaense. Nestas produções, a autora buscou criar um sistema de referências para classificar os produtores de história e, assim, organizou uma linha evolutiva do modo como se fez história em diferentes temporalidades. Sua baliza decisiva foi a historiografia universitária da década de 1960 que, por sofisticar o campo historiográfico, corporificou o métier do historiador cientista. Seu exercício avaliativo retrospectivo também colocou em perspectiva as reminiscências de sua formação como historiadora e, então, apropriando-se deste gênero de escrita, Westphalen sugeriu o lugar que deveria ocupar na história da historiografia paranaense. É este processo de construção distintiva do historiador universitário, concomitante à construção da justificação de sua trajetória intelectual, que este artigo interpretará.

O presente dossiê propõe como eixo reflexivo repensar possibilidades de escrita da história e, consequentemente, problematizar formas, intenções narratividades e potenciais representativos, ressaltando assim a força evocativa do suporte visual, o posicionando como elemento constituinte da linguagem, extrapolando, portanto, uma função meramente ilustrativa, e redimensionando o poder da imagem como expressão em si.  Os artigos aqui reunidos inscrevem-se nesse horizonte e são resultantes de pesquisas inovadoras tanto nos temas quanto na forma, recolha e análise de fontes.

Published: September 2017

This research aimed to investigate the feasibility of using self-compacting concrete in civil engineering applications as a producing a precast hollow unit. The behavior of the hollow sections cast with self-compacted concrete beneath line-load was evaluated. An experimental work was carried out and a finite element model with ANSYS (version 15) was adopted. A total of fourteen hollow beams were cast and tested. The most variables taken into thought were; the types of reinforcement (reinforced steel bar and steel wire meshes), the types of steel wire meshes (expanded and welded steel wire mesh), number of layers of steel meshes (one layer and two layers), cross section thickness of concrete (40 mm and 60mm), concrete cover thickness (15mm and 20 mm) and also the shapes of cross section (square or circular). Special attention to initial cracking load, ultimate load, deflection, cracking pattern, energy absorption and ductility index were investigated. Good agreement was found compared with the experimental results. Out of this research; this paper presents applications of self-compacted concrete for casting skinny structural hollow members. These members can be used as precast units within the construction of the tunnel to decrease the problems in highway roads due to the difficulty of using crossing bridges particularly for kids and old people which are very useful for developing countries with great economic advantages.

This study aims to investigate modal parameters such as mode shapes, natural frequencies and damping ratios of a reduced scale one-span historical masonry arch bridge constructed in laboratory conditions by performing numerical and experimental analysis. Sarp Dere historical masonry bridge, in Ordu, Ulubey, has 15.5m in length and 4.75m in width was chosen as a prototype model. The reduced-scale bridge model and structural details were carried out in the scale of 1:12.5. Operational Modal Analysis (OMA) technique was used for experimental study. The experimental modal parameters of the bridge model were figured out by using Enhanced Frequency Domain Decomposition (EFDD). ANSYS software was used to create 3D finite element (FE) model and to expose the analytical modal parameters of the reduced-scaled bridge model. Moreover, FE model of the reduced-scale bridge model was calibrated based on the experimental results by using the Response Surface based FE model calibration technique to obtain more accurate results. The analysis results of experimental, initial and calibrated FE model were compared. It is noted that there are significant differences between the modal parameters obtained from experimental and initial FE model. Model calibration techniques are beneficial to get a more reasonable FE model.
Vertical stiffeners and internal pressure - influencing factors on distribution of meridional stresses in steel silos on discrete supports
Authors: Zdravkov Lyubomir A.
Published: September 2017

Steel silos are interesting, complicated facilities. In order to ensure unloading of whole amount of stored product by gravity, they are often placed on supporting structure. Values of stresses in joints between thin sheets and supporting frame elements are very high, which could cause local loss of stability in thin shells. Many researchers have worked on values and distribution of the meridional stresses in that joints. Their traditional approach is to divide in their minds cylindrical shell on two parts - discretely supported ring beam and continuously supported shell above it. As a result of their efforts critical height of shell Hcr and ideal position of intermediate stiffening ring on shell are determined. The scientific results are based on semi-membrane theory of Vlasov, in which influence of vertical stiffeners and internal pressure is not accounted. On other hand all steel silos are loaded with an internal pressure and majority of them have vertical stiffeners above supports. Is it possible the obtained scientific results to be applied to these silos? In a present article the author will show that stiffeners and pressure should not be ignored in an analysis.
Spatial Dependence Modeling of Wind Resource under Uncertainty Using C-Vine Copulas and Its Impact on Solar-Wind Energy Co-Generation
Authors: Narayan Apurva , Ponnambalam Kumaraswamy , Pagsuyoin Sheree A.
Published: September 2017

Investments in wind and solar power are driven by the aim to maximize the utilization of renewable energy (RE). This results in an increased concentration of wind farms at locations with higher average wind speeds and of solar panel installations at sites with higher average solar insolation. This is unfavourable for energy suppliers and for the overall economy when large power output fluctuations occur. Thus, when evaluating investment options for spatially distributed RE systems, it is necessary to model resource fluctuations and power output correlations between locations. In this paper, we propose a methodology for analyzing the spatial dependence, accurate modeling, and forecasting of wind power systems with special consideration to spatial dispersion of installation sites. We combine vine-copulas with the Kumaraswamy distribution to improve accuracy in forecasting wind power from spatially dispersed wind turbines and to model solar power generated at each location. We then integrate these methods to formulate an optimization model for allocating wind turbines and solar panels spatially, with an end goal of maximizing overall power generation while minimizing the variability in power output. A case study of wind and solar power systems in Central Ontario, Canada is also presented.
