Application of an Integral Methodological Approach to Measuring the Dynamics of the Basic Digital Divide
Authors: Dolničar Vesna
Published: February 2019

The paper illustrates that, when analysing the dynamics of the digital divide, the answer to the seemingly simple question ‘Is the digital divide increasing, decreasing, or is it constant?’ is not straightforward. An integral methodological tool that comprehensively addresses this question will be introduced. This methodological approach is based on the assumption that none of the existing statistical measures truly communicates the essence of a certain digital divide phenomenon (absolute measures, relative measures and S-time-distance are considered). In addition, even the simultaneous reporting of all three measures is insufficient. To monitor and interpret the dynamics of the digital divide it is therefore very important to explicitly take into account future scenarios of ICT diffusion among the observed subjects (e.g. population segments, countries…). We have developed these scenarios within the broad framework of the diffusion theory (Rogers, 1962, 2003), but with a distance from two of its implicit assumptions related to the deterministic conceptualisation of the diffusion process: the form of the diffusion function and the anticipated level of the final penetration rate. It is argued that the proper measure can only be provided if we anticipate and take into account the full distribution functions of the compared subjects or population segments and the location of the subject at a certain point in time.

Background

Anatomic location of primary tumors across the colon correlate with survival in the metastatic setting, whereas left-sided tumors may exhibit superior survival compared with right-sided tumors. The Oncotype Recurrence Score (RS) assay is a clinically validated predictor of recurrence risk in patients with stage II colorectal cancer (CRC). Previous studies had indicated that without adjuvant chemotherapy, CDX2-negative stage II CRC tumors are associated with a lower rate of disease-free survival than CDX2-positive stage II CRC tumors. We aimed to evaluate whether these two validated prognostic biomarkers may correlate with primary tumor location, and whether tumor location may reflect differential prognosis in stage II CRC.

Materials and Methods

We retrospectively analyzed patients with T3 mismatch repair-proficient (MMR-P) stage II CRC for whom RS assay was performed. Pathological report was reviewed for exact primary tumor location and CDX2 immunostaining. RS and CDX2 expression were correlated with primary tumor location.

Results

The analysis included 1,147 patients with MMR-P stage II CRC (median age 69 years [range 29–93]). Tumor distribution across the colon was as follows: 46% (n = 551) were right-sided and 54% (n = 596) were left-sided. RS was higher in right-sided tumors (p = .01). The RS results gradually decreased across the colon (cecum, highest score; sigmoid, lowest score; p = .04). Right-sided tumors exhibited more CDX2-negative tumors (p = .07).

Conclusion

Our study indicates that right-sided colorectal tumors may display worse prognosis compared with left-sided tumors in MMR-P stage II CRC. Primary tumor location may serve as a prognostic factor that should be taken into account for recurrence risk assessment and consideration of adjuvant treatment.
Material and glass-fibre-reinforced polymer bond properties of geopolymer concrete
Authors: Dong Minhao , Feng Wei , Elchalakani Mohamed , Li Gang Kevin , Karrech Ali , Sheikh M. Neaz
Published: February 2019

Geopolymers are recognised for their environmental benefits and excellent chloride and sulfate resistance. However, information on the material characteristics and bond behaviour of geopolymers based on fly ash (FA) and slag is still relatively scarce. This paper presents a comprehensive study on the integration of two modern construction materials – geopolymer concrete (GPC) based on FA and ground granulated blast-furnace slag and glass-fibre-reinforced polymer (GFRP) bars. The aim of the study was to assist concrete structural design by identifying the key preparation parameters such as hardening and bond behaviour. It was found that the hardening of the GPC was much faster than that of ordinary Portland cement (OPC) concrete at an early age and the stress–strain curves, elastic moduli and splitting tensile strengths of the GPC were accurately predicted by existing models developed for OPC concrete. The GFRP bars in the GPC outperformed those in the OPC concrete in terms of normalised bond strength. The GPC reinforced with both GFRP and steel rebars exhibited similar bond–slip curves to the OPC concrete. Overall, the behaviour of the GFRP-reinforced GPC was found to be analogous to that of the OPC concrete while providing adequate compressive, tensile and bond strength for the construction of foundations of low-rise buildings.

Produção de subjetividade pelas práticas do vestir no Brechó de Troca: novos campos para a psicologia social
Authors: Soares Helena De Barros
Published: February 2019

O presente artigo mostra como o sistema da moda vem produzindo modos efêmeros de práticas do vestir calcadas no consumo frenético, a partir do olhar problematizador da relação do sujeito com a roupa enquanto produção de subjetividade. Se outrora a moda foi ferramenta para diferenciação de classes e setores sociais, hoje a produção de subjetividade implica em modos de parecer para ser.  Tal efemeridade produz efeitos que a Psicologia Social pode ler como demanda para produção de projetos e modos de escuta de atuações já existentes. O projeto do Brechó de Troca é descrito como campo da Psicologia Social, de abordagem ético-estética e política. E um espaço de convívio onde o escambo é um chamariz para possíveis encontros, um grupo que resiste aos modos efêmeros de consumo de moda. O artigo mostra as condições de possibilidade para a criação do Projeto que, em janeiro de 2019 faz 10 anos de existência sempre resistindo aos recursos perversos do mercado de moda.
METÁFORAS MULTIMODAIS SOBRE A REFORMA DA PREVIDÊNCIA SOCIAL NO BRASIL: UMA ANÁLISE SEMÂNTICO-COGNITIVA NO GÊNERO CHARGE
Authors: Andrade Luiz Henrique Santos , Silva Marcos Antônio da
Published: February 2019

Este artigo tem como objetivo descrever e analisar as metáforas multimodais acionadas pela representação pictórica aliada às manifestações linguísticas presentes em charges que versam sobra a reforma da previdência social no Brasil. A fim de atingir o objetivo firmado, nosso trabalho está balizado na Teoria das Metáforas Multimodais, conforme os estudos de Forceville (2009), Forceville e Urios-Aparisi (2009) e Sperandio (2014). Lançamos mão também dos estudos sobre o Sistema Metafórico da Moralidade, de acordo com Lakoff e Johnson (1999) e Lakoff (2016 [1996]). O corpus é composto por seis charges que foram coletadas nos meses de setembro, outubro, novembro e dezembro de 2017 em dois sites especializados, a saber: A Charge Online e Humor Político. Através desta pesquisa, concluímos que os produtores de charges categorizam a reforma da previdência social ora como comércio/negociata, ora como assalto e ora como sujeira. Foi constatado que as metáforas multimodais corroboram com as críticas feitas pelos chargistas, e possuem também a função semântico-discursiva de denunciar/criticar situações e pessoas públicas do nosso dia a dia.
Figurações multimodais com bandeiras nos grafites de Banksy: a arte como protesto sociopolítico
Authors: Bastos Arantes Rita de Cássia , Almeida Maria Clotilde
Published: February 2019

À luz da Linguística Cognitiva (LAKOFF; JOHNSON, 1980 e LAKOFF; TURNER, 1989) e da Teoria da Metáfora Multimodal (FORCEVILLE, 2008, 2009), este estudo tem por objetivo analisar três grafites de Banksy: Sweatshop boy, Les Misérables e Brexit, apresentando os mapeamentos metafóricos e metonímicos que estruturam as suas representações multimodais e monomodais. Adicionalmente, com base no conceito cognitivo de arte (DONALD, 2006) e no conceito de cultura visual como prática social (BARNARD, 1998), demonstraremos que a criatividade metafórica de Banksy não está a serviço simplesmente de uma forma de arte auto expressiva, mas sim fortemente orientada para a crítica social, como é o caso do uso de bandeiras para retratar os modelos sociopolíticos das nações que elas representam. Por último, a partir da concepção de que ARTE É ARMA, apresentaremos a nossa interpretação para cada um dos grafites, mostrando que além de instituírem manifestações da estética elaborada, os grafites de Banksy são sobretudo poderosos instrumentos de protestos sociopolítico.

Published: February 2019

O trabalho do homem, quando executado de forma exaustiva, pode trazer consequências prejudiciais ao seu corpo, pela exigência física, esforços transmitidos pelos equipamentos e, principalmente, pela postura necessária para o desenvolvimento de uma determinada atividade. Com isso, o objetivo do trabalho foi avaliar as posturas realizadas durante a jornada de trabalho de um operador de trator agrícola na atividade de preparo do solo em área de várzea. Para a coleta de dados, foi realizado o acompanhamento da atividade em uma propriedade rural, no município de Ivorá – RS, por meio de registros fotográficos das posturas do operador ao longo da jornada de trabalho diária, além da contagem do número de viradas do operador para trás e o tempo em que permanecia nessa posição. A análise postural foi efetuada com os métodos OWAS, RULA e REBA, sob uso do software Ergolândia 6.0. As análises permitiram observar que as posturas de rotação do tronco para trás diminuíram ao longo da jornada de trabalho e foram impulsionadas, possivelmente, pela fadiga ocasionada pelo trabalho. Ainda, a análise geral dos métodos demonstraram a necessidade de intervenção ergonômica à curto prazo, como o apoio de membros superiores durante a realização da tarefa.

O Brasil se destaca como grande produtor mundial na avicultura, liderando como o maior exportador de carne de frango do mercado, sendo sete anos de liderança nas exportações. O bem-estar animal está intimamente ligado à produtividade e as condições de ambiência devem respeitar as normas estabelecidas para que haja maior rendimento de produção e ética para com as aves; é preciso utilizar estratégias para modificar o ambiente interno das instalações destinadas á criação de aves. Desta forma este trabalho teve por objetivo produzir painéis arquitetônicos para forro, utilizando resíduos provenientes da agroindústria (casca de arroz, fibra de coco e polipropileno) e que foram aplicados em um protótipo para os aviários. Para avaliação dos painéis produzidos foram realizados os ensaios de propriedades físico-mecânicos e térmicos, de acordo com a norma NBR 14810 (2013), e selecionado o tratamento com 50% polipropileno + 30% casca de arroz + 20 fibra de coco. Foi avaliado o desempenho dos painéis aplicados nos protótipos como galpões em escala reduzida, situados na Faculdade de Ciências Engenharia, UNESP (Tupã) onde o clima da região é tipo Cwa (Clima tropical de altitude) segundo a classificação de Köppen, estação seca bem definida durante o inverno. A avaliação destas instalações demostraram que o uso do forro com o material proposto atingiu as faixas de termoneutralidade e de conforto térmico para aves com três semanas de vida em dois horários (12h e 16h), complementando com a análise termográfica, onde constatou valores médios superiores em 10,6°C para a instalação sem forro, comprovando o isolamento térmico para a instalação com forro.

THE AGREEMENT BETWEEN THE COMMUNIST POWER AND THE POLISH EPISCOPATE OF 1950
Authors: Antoniuk O.
Published: February 2019

The article explores the process of preparation and signing of the Agreement between the representatives of the government of Polish Republic (PR) and the Polish Episcopate during the first four months of 1950. The main focus is on the policy of communist power regarding the Catholic Church. The essence of this policy was to continue to exert pressure on the church in order to force it to sign an agreement on favorable conditions for the power. Repressive measures of the ruling regime are highlighted. The principal position of the Polish primate S. Vyshynsky concerning the negotiation process is established. The main provisions of the Agreement between the representatives of the government of PR and the Polish Episcopate are analyzed. The article gives an assessment of the results of the agreement by the party-state leadership of Poland, which has made from the Catholic Church its official recognition and some significant concessions. However, the authorities continued to declare their tolerance towards religion and pledged not to restrict church activities and teach religion in schools. The results of the signing the agreement for the Catholic Church in Poland, which received a temporary respite in confrontation with the authorities, are described. The agreement became a kind of shield for the church from the further aggression of party-state structures.

Published: February 2019

The tragic Deepwater Horizon accident in the Gulf of Mexico in 2010 as well as the increase in deepwater offshore activity have increased public interest in counter-measures available for subsurface
releases of hydrocarbons. To arrive at proper contingency planning, response managers urge for a system for instant detection and characterization of accidental releases. Along these lines, this
paper describes the application of a heterogeneous robotic system of unmanned vehicles: autonomous underwater vehicle (AUV), unmanned surface vehicle (USV) and unmanned aerial vehicle (UAV)
extended with the oil spill numerical modeling, visualisation and decision support capabilities. A first set of field experiments simulating oil spill scenarios with Rhodamine WT was held in Croatia during
the early autumn 2014. and the second set of experiments were held in Spain during the summer 2015. The objectives of this experiment were to test: effectiveness of the system for underwater detection of
hydrocarbons, heterogeneous multi-vehicle collaborative navigation and communication as well as decision support system, visualisation of the system components and detected spill.

Published: February 2019

The study presents an analysis of the impact produced by the construction and modernization of road connections on the improvement and development of the port of Rijeka container terminal and on the growth of its competitiveness on the northern Adriatic traffic route. The paper focuses on the smoothing technique implementation as a quantitative prognostic method for road traffic. Considering the importance of container traffic within the total freight traffic in the port of Rijeka, prognostics is presented for lorry traffic on State road D – 404, which connects the container terminal of Brajdica to the expressway network to the hinterland. Thereby, the potential substratum gravitating to the container terminal and to the pertaining traffic route has been evaluated. Following description of the geographical, traffic-related and logistic situation of the port of Rijeka, the paper continues with technical and technological features of the container terminal of Brajdica and, in addition, with the significance of State road D – 404 for development of the container terminal of Brajdica and an analysis of lorry traffic trends on State road D – 404. Whereas there are confirmed assertions that there are significant differences found quite often between projected values and those ones actually obtained, the expected traffic trend values obtained by applying the smoothing technique using the moving averages method for 2017 have been assessed as satisfactory.

Este trabajo parte de la premisa de que en países desarrollados la industria de alta tecnología (IAT) presenta mayor encadenamiento productivo, que le permite propagar cualquier tipo de impulso al crecimiento. El documento cuestiona el papel de la IAT en la expansión de innovaciones  para las economías de Colombia y México. Con el análisis cualitativo de insumo – producto, se prueba que el grado de propagación de la IAT es parecido entre las economías. Los resultados señala a groso modo, mientras que Colombia tiene una propagación innovadora más alta que México, este último tiene mayor efecto sobre el producto, no obstante, en ambas economías la IAT es difusora, pero no recibe innovaciones tan solo cuando se utilizan los insumos intermedios importados en el proceso productivo.
La Organización del Tratado del Atlántico Norte y la ampliación al Este: ¿hasta Ucrania?
Authors: Martínez Carmena Maria
Published: February 2019

En este estudio se analiza la política de ampliación de la OTAN durante la Posguerra Fría, y las razones del actual estancamiento de la denominada política de puertas abiertas. Si bien es probable que todos los Estados balcánicos acaben integrados en la OTAN, otros Estados han sido configurados por parte de Rusia como el muro infranqueable de este proceso ampliador. En este sentido, Georgia y, de forma clara, Ucrania han marcado un punto de inflexión en la relación entre la OTAN y Rusia. El “factor Rusia” siempre ha determinado el avance de la Alianza Atlántica hacia el Este de Europa, pero actualmente los miembros de la OTAN, principalmente los socios europeos más relevantes, podrían verse afectados por graves implicaciones de orden político, económico y geoestratégico (energía, coordinación para combatir el terrorismo yihadista, etc.) si su relación con Rusia empeora. Por ello, se considera adecuado que la estrategia de la ampliación en esta etapa atienda a todas las variables, revise sus objetivos y no se realice de forma precipitada, dado que la reconstrucción de la relación con Rusia es fundamental para que exista un equilibrio euroasiático.
La importancia de corea del norte para China
Authors: Patiño García Camilo
Published: February 2019

El presente trabajo examina la reciprocidad de alianza y dependencia de la República Popular de China (China) con la República Popular Democrática de Corea (Corea del Norte), estableciendo desde una posición neorrealista en Relaciones Internacionales que, si bien Corea del Norte depende de China para su estabilidad interna y de seguridad externa, China mantiene esta alianza como elemento prioritario de desarrollo y seguridad geopolítica. Se plantea una visión historica de la relación para mostrar el factor de conveniencia en sus constantes distanciamientos y acercamientos, y se analizan los componetes militar y economico como factores de poder, así como el institucionalismo internacional como un elemento que aporta al realismo en la política China hacia Corea del Norte. De tal forma, se muestra  que las acciones de China en apoyo a Corea del Norte, sobre todo en el ámbito económico y políticos, no están supeditados al alejamiento norcoreano de las normas y estándares del sistema internacional, sino a la estructuración de una península coreana estable, con un aliado que le permita un equilibrio de poder geopolítico no supeditado a otros Estados.
Estimadores encogidos en modelos de ecuaciones simultáneas para el análisis del mercado de carne de bovino en México
Authors: López García María del Rosario , Ramírez Valverde Gustavo , Ramírez Valverde Benito , Terrazas González Gerardo H.
Published: February 2019

El objetivo principal en este trabajo fue usar regresión LASSO (Least Absolute Shrinkage and Selection Operator) como método de selección de instrumentos en la estimación de mínimos cuadrados en dos etapas (Mc2E) en un sistema de ecuaciones simultáneas propuesto para realizar un análisis econométrico del mercado de carne de bovino en México en el periodo 1972-2011. Un factor determinante en el desempeño de los estimadores es el grado de correlación de los instrumentos con las variables endógenas en la primera etapa. Cuando los instrumentos son débiles, los estimadores de Mc2E son inconsistentes, sesgados, y tienen varianzas grandes; los resultados asintóticos fallan incluso con muestras grandes. Los resultados muestran que mediante lasso es posible seleccionar instrumentos relevantes, y obtener mejores estimadores que redunden en un mejor diseño de políticas.
Estudio empírico sobre el tipo de cambio mxn/usd: movimiento browniano geométrico versus proceso varianza-gamma
Authors: Mosiño Alejandro , Salomón-Núñez Laura Andrea , Moreno-Okuno Alejandro Tatsuo
Published: February 2019

En este artículo examinamos el comportamiento del mercado cambiario en México, el cual se caracteriza por movimientos extremos muy frecuentes ocasionados por la información generada dentro del mercado financiero y el entorno macroeconómico internacional. Modelamos estos movimientos extremos utilizando un proceso varianza gamma, el cual nos permite capturar el sesgo y el exceso de curtosis de los rendimientos del tipo de cambio. Concluimos que, en general, este proceso ajusta mejor a los datos que el movimiento browniano geométrico – basado en la densidad normal– y nos permite estimar con mayor precisión el Valor en Riesgo (VaR). Mostramos, además, que el ajuste mejora conforme aumenta la ventana temporal utilizada para calcular los rendimientos del mercado cambiario.Finalmente, realizamos un backtesting del VaR mediante la prueba de Kupiec.
Effect of the Fexofenadine on the expression of HRH-1 and HRH-4 receptor in Peripheral Blood Mononuclear Cell isolated from children with diagnosed allergy – in vitro study Short communication
Authors: Kordulewska Natalia , Cieślińska Anna , Fiedorowicz Ewa , Jarmołowska Beata , Kostyra Elżbieta
Published: February 2019

Purpose: Fexofenadine (FXF) is the active metabolite of terfenadine with selective peripheral H1 receptor antagonist activity. FXF is a third-generation antihistamine, non-sedating, rapid and very long acting used in symptoms associated with allergic diseases such as allergic rhinitis, asthma and dermatitis. The pleiotropic effects of histamine are mediated by four types of receptors that belong to the G-protein-coupled receptor family: histamine H1 receptor (HRH-1), histamine H2 receptor, histamine H3 receptor, and histamine H4 receptor. Our hypothesis is that HRH-4 opens new possibility in treatment in allergy diseases and FXF could be the antagonist of both HRH-1 and HRH-4. Methods: We isolated a peripheral blood mononuclear cell (PBMC) from children with diagnosed allergies and healthy – control group and measured the HRH-1 and HRH-4 mRNA gene expression using Quantitive Real-Time PCR. We obtained the results from basal gene expression and after FXF and histamine stimulation. Results: HRH-1 mRNA basal gene expression shows significantly higher, and HRH-4 shows significantly lower expression in allergy group compared to control. In both groups HRH-1 mRNA gene expression was observed as statistically significant increased after histamine stimulation compared to cells not treated, while in HRH-4 only in allergy group we observed statistical increase. FXF successively blocked histamine affinity in HRH-1 mRNA gene expression but not in HRH-4, where we not observed any reaction. Conclusions: Results clearly overturned our hypothesis about the possibility of using FXF to block over-expression HRH-4 and open new way of treatment in allergy diseases.
Acceptable noise levels in Arabic-Persian bilinguals
Authors: Taheri Fateme , Geshani Ahmad , Fatahi Jamileh , Jalaie Shohreh , Tavakoli Mojtaba
Published: February 2019

Background and Aim: Acceptable noise level (ANL) test is a reliable measure of people’s abi­lity to tolerate background noise. Central ner­vous system is one of the determinant factors in subject’s tolerance of noise. Bilinguals’ diffe­rent central activity pattern may yield different ANL test results from monolinguals. This study aims to compare noise tolerance function in Arabic-Persian bilinguals with Persian monolin­guals via Persian version of ANL.
Methods: In the present study, the Persian ver­sion of ANL was administered on 115 cases with normal hearing (56 male, 59 female) aged 18–37 years in three groups of the Persian mon­olingual, sequential Arabic-Persian bilinguals, and simultaneous Arabic-Persian bilinguals.
Results: The statistical analysis revealed sig­nificant difference in most comfortable level (p = 0.002) and background noise level (p = 0.011) among three groups, i.e. between Persian monolinguals and sequential Arabic-Persian bil­inguals and between Persian monolinguals and simultaneous Arabic-Persian bilinguals. In other words, mean scores of bilingual were higher than monolingual scores. There was no signifi­cant difference among three groups with regard to ANL scores (p = 0.114).

Conclusion: Despite the difference between Persian monolinguals and Arabic-Persian bilin­guals in most comfortable level and background noise level, there is no significance difference in ANL results. Therefore, auditory central proce­ssing acts similarly in normal hearing monolin­gual and bilingual subjects. As a result, Persian version of ANL can be used for Arabic-Persian bilinguals, too.

Objective: The present study aimed at estimating the case fatality rates of suicide acts in different marital status subgroups and to find interrelation with a population living in Bushehr province along the coastal region of the Persian Gulf coast in southwest of Iran.
Method: In this analytical and observational study, suicidal data were gathered in 5 successive years (2008–2012) in the population of Bushehr. Data were extracted from suicide registration forms provided by the Psychiatric Health Unit of Ministry of Health. Questions mainly focused on demographic characteristics, including age, sex, literacy, residency, marital status, birth rank, the number of previous suicide attempts, and probable reasons of suicide, such as family conflicts or/and psychiatric complications. Fatality rates in different subgroups (male/female; married/unmarried; etc.) were compared and odds ratios were computed. The main limitation of this study was the lack of a specific grouping for those who cohabited together (Those who live together and have a sexual relationship without being married). The logistic regression model was used in data analysis.
Results: Case mortality rates of suicides were found to be 3.5% for both sexes, 5.2% in males and 2.7% in females. However, among the single population, either divorced or widowed, the probability of death due to suicide was 3.5 times higher (95% CI: 1.5–2.9) as compared to the unmarried. Age as a confounding factor in fatality rates made a significant difference between married and unmarried people, and differences disappeared after adjusting for age. However, fatality rate was still higher in the widowed /divorced group compared to other groups even after adjusting for age.
Conclusion: Fatality rate was higher in married people compared to the unmarried, however, after adjusting for age as a determinant factor, no significant difference was observed between the 2 groups. The highest death rate belonged to the age-specific widowed /divorced individuals as compared to all other marital status subgroups.

Pollution with the heavy metals of Kosovo's rivers has been and continues to be a serious concern not only for the population, but also for responsible institutions that deal with environmental protection in our country. Based on this fact and our doubts regarding the quality of the river waters of the Municipality of Gjilan, we were motivated to conduct a study of the quality of the Mirusha, Stanishor and Morava river waters. During our research, we have set eight monitoring points for determining the exact level of concentration of heavy metals in the river waters quoted above. The heavy metals analyzed in this study were: Pb, Hg, Mn, Cu, Fe, Ni, Cr, Cd, Zn and Ba. The analytical technique used to determine the concentration of heavy metals was ICP-OES. The obtained results show that Fe, Mn and Ba exceed the allowed level at several monitoring points of the Mirusha and Stanishor rivers and appears in the degree of pollution with these metals of Morava river waters. The presence of heavy metals in the waters of these rivers negatively affects habitat waters and indirectly human health. Therefore, the identification and then suggestions regarding elimination of polluting sources are the subject of this study.

Le développement folliculaire et l’occurrence de l’ovulation ont été étudiés chez la chèvre du Sahel en œstrus induits. Quinze femelles d’âges et de poids moyens respectifs de 37,25 ± 1,5 mois et 32,5 ± 7,3 kg, et de parité comprise entre 1 et 3 ont été traitées à l’aide d’éponges intravaginales (acétate de fluorogestone, 20 mg/éponge) pendant 11 jours. Ce traitement a été associé à l’administration intramusculaire par animal de 400 UI de gonadotrophine chorionique équine (eCG) et de 2 ml de cloprosténol le neuvième jour. La détection de l’œstrus a été réalisée par observation visuelle après l’introduction de deux boucs fertiles dans le troupeau. Le développement folliculaire a été suivi par échographie à intervalles de 12 heures au moyen d’une sonde linéaire de 5 MHz. Le délai moyen d’apparition de l’œstrus a été de 15,4 ± 2,9 h. L’œstrus a été matérialisé par des écoulements vulvaires et des tentatives de chevauchements entre congénères. Sa durée moyenne a été de 32,3 ± 3,8 h. A l’arrêt du traitement, 13 follicules ont été observés sur l’ovaire droit et 13 follicules sur l’ovaire gauche avec des diamètres moyens respectifs de 5,26 ± 1,25 mm et de 4,73 ± 1,45 mm. Le diamètre moyen du follicule préovulatoire a été 7,6 ± 2,1 mm. Ce diamètre a varié selon l’ovaire. Au total 17 ovulations ont été enregistrées dont huit dans l’intervalle entre 45 et 50 heures après la fin du traitement. Ces résultats sont des éléments de repère précieux pour l’application des biotechnologies de la reproduction chez cette race.

Published: February 2019

Edifícios de escritório com múltiplos pavimentos, em sua maioria, possuem grandes superfícies envidraçadas que possibilitam aos usuários usufruir de luz e ventilação natural, além do contato do observador com o meio externo. Entretanto, sem um devido tratamento, essas superfícies podem possibilitar aumento/redução de carga térmica para o edifício, assim como causar ofuscamento nos trabalhadores. Neste sentido, a janela fotovoltaica poderia ser utilizada tanto para melhorar a distribuição da iluminação natural quanto para suplementar energia para iluminação artificial quando necessária. O objetivo dessa pesquisa é avaliar o potencial da aplicação de Dispositivos Orgânicos Fotovoltaicos (OPV) em janelas laterais de edifícios de escritórios com múltiplos pavimentos e salas profundas, a fim de verificar a sua contribuição em relação à qualidade da iluminação natural no ambiente interno. Realizou-se a avaliação por meio de um experimento com um modelo em escala reduzida de uma sala de escritório genérica, iluminada por uma janela lateral, a qual corresponde a 100% da área da fachada Norte. Compararam-se três tipos de materiais para a janela sob condição de céu real em Curitiba-PR: Cenário A - vidro simples 3 mm; Cenário B – vidro e OPV; e, Cenário C – vidro com aplicação de película solar. Apesar da redução da iluminância com a utilização dos materiais dos cenários B e C em relação ao material do cenário A, constatou-se uma melhor distribuição da iluminação natural no interior da sala, sendo que no cenário B existe a possibilidade de utilizar a energia gerada na janela fotovoltaica para a iluminação artificial.
