Authors: Pereira Heloisa Ramos , Reboita Michelle Simões , Ambrizzi Tércio
Published: June 2017

Resumo O El Niño (EN) é caracterizado pelo aquecimento anômalo das águas superficiais do oceano Pacífico Tropical central e leste que afeta o clima global e regional através das anomalias da circulação da atmosfera. O EN 2015/2016 foi classificado como um evento muito forte. Portanto, esse estudo tem como objetivo mostrar as características da atmosfera durante a ocorrência desse evento nos meses de setembro, outubro e novembro de 2015. Entre os resultados, têm-se o deslocamento para leste da célula de circulação zonal de Walker, intensificação dos jatos subtropical e polar, presença de anomalias positivas de altura geopotencial no oceano Pacífico próximas ao sul da América do Sul e anomalias negativas no sudeste desse continente e no oceano Atlântico. Além disso, há maior frequência de ciclones nas latitudes subtropicais do oceano Atlântico e convergência do fluxo de umidade integrado na vertical sobre o sudeste da América do Sul. Essas características contribuem para anomalias de precipitação e temperatura do ar na América do Sul.

Published: June 2017

Resumo Este estudo investigou as principais características atmosféricas associadas a eventos extremos de precipitação com uma defasagem de três dias antes da ocorrência desses extremos. Os extremos foram definidos quando na maior parte dos pontos de grade sobre o Nordeste do Brasil (2° S-12° S e 45° W-37° W), as chuvas diárias foram iguais ou superiores a 50 mm. Foram utilizados dados diários de precipitação de um conjunto de estações pluviométricas distribuídas sobre o NEB, provenientes das redes observacionais pertencentes ao Instituto Nacional de Meteorologia, Agência Nacional de Águas e Núcleos Estaduais de Meteorologia e Recursos Hídricos, cobrindo o período de 1974-2003. Estes dados foram interpolados espacialmente, usando a técnica do inverso do quadrado da distância, para uma grade regular com resolução de 1° de latitude e longitude (aproximadamente 111 km). Para análises das características atmosféricas foram usados dados de reanálises de variáveis atmosféricas como: vento zonal meridional, temperatura do ar, umidade relativa e outras das reanálises do NCEP-NOAA desde a superfície até 200 mb. Os resultados mais expressivos mostraram que três dias antes dos eventos de precipitação considerados extremos, há uma incursão de ar frio para a área central do NEB, intensificando um dia antes dos dias dos eventos, com anomalias inferiores a −4 °C, que não aparecem para os eventos considerados de pouca precipitação sobre a região.
Rediscutindo conceitos na antropologia da saúde: notas sobre os agenciamentos terapêuticos
Authors: Tavares Fátima
Published: June 2017

Resumo Este artigo questiona o uso de alguns conceitos teóricos na investigação dos processos de cura na contemporaneidade. O argumento principal que apresento é que os modelos interpretativos ancorados em dicotomias e classificações podem “engessar” conceitos como corpo, sujeito e experiência, pouco auxiliando a investigação e compreensão das mediações e eficácias mobilizadas nos contextos terapêuticos. Para dar suporte a este argumento, começo apresentando alguns dilemas em torno da própria constituição do objeto da antropologia do corpo e da saúde, nas “escolhas” terapêuticas em situações etnográficas de populações indígenas e em contextos de adesão religiosa; a seguir, passo pela crítica de alguns conceitos-chave daquele campo da antropologia; ao final, proponho o conceito de agenciamento terapêutico como abordagem alternativa às discussões sobre experiência e itinerário terapêuticos.
Cardinal temperatures for the leaf development of Corymbia citriodora and Eucalyptus urophylla seedlings
Authors: Freitas Cleverson Henrique de , Martins Fabrina Bolzan , Abreu Marcel Carvalho
Published: June 2017

Abstract: The objective of this work was to estimate cardinal temperatures and phyllochron for the leaf development of the eucalyptus species Corymbia citriodora and Eucalyptus urophylla, in the seedling phase. A field experiment was carried out in a completely randomized design, in a 2x11 factorial arrangement, with the two eucalyptus species, 11 sowing dates, and five replicates, in the municipality of Itajubá, in the state of Minas Gerais, Brazil. The cardinal temperatures - base, optimum, and maximum - for leaf development were, respectively, 8.7, 17.1, and 41.3°C, for C. citriodora, and 11.5, 17.1, and 40.5°C for E. urophylla. The phyllochron of C. citriodora was 62.95°C day per leaf, and that of E. urophylla was 46.03°C day per leaf, which indicates that E. urophylla requires less energy accumulation than C. citriodora for leaf emission in the main stem.
Habitação de Interesse Social rural na região metropolitana de Maringá, PR: avaliação pós-ocupação
Authors: Moreira Fábia Rosas , Silva Ricardo Dias
Published: June 2017

Resumo Este artigo apresenta um estudo do projeto arquitetônico da unidade de habitação do programa Vila Rural (VR), implantado no estado do Paraná entre os anos de 1995 e 2002. O método utilizado foi a avaliação pós-ocupação (APO), e teve como instrumentos: walkthrough, entrevistas, questionário e medições físicas, por meio dos quais foi possível obter informações que dizem respeito à real apropriação que as famílias de moradores rurais fizeram de suas unidades com o passar do tempo, sendo observadas alterações significativas feitas em suas residências. A maioria dos moradores alteraram suas unidades de forma a quase não mais ser possível a identificação do projeto inicial. Os resultados apontam quais ambientes sofreram alterações, como a planta evoluiu em área e a técnica construtiva empregada nessas reformas. A metragem quadrada por morador obteve um grande acréscimo de seu valor. Assim, é possível afirmar que o projeto arquitetônico original e o programa habitacional não atenderam as reais necessidades dos usuários ao não considerarem seu modo de vida e as especificidades da moradia rural.
Predictions of footing and pressuremeter response in sand using a hardening soil model
Authors: Bagbag Ahmad A. , Lehane Barry M. , Doherty James P.
Published: June 2017

The paper presents the results and interpretation of triaxial compression tests for a uniformly graded fine to medium siliceous sand. These results are used together with data obtained from boundary value problems to provide an objective assessment of the predictive capabilities of a widely accessible and popular constitutive model, referred to as the HSS (hardening soil small) or hardening soil model with a small strain overlay. The triaxial compression tests, which involved a range of relative densities and stress levels, are used to derive model parameters providing the optimal fit to the triaxial experiments. Measurements obtained in pressuremeter and footing experiments performed in a laboratory testing chamber with the same reconstituted sand are then compared with finite-element analyses of these experiments using the selected model parameters These comparisons combined with a review of simulations for the triaxial tests are used to draw conclusions related to the application of the HSS model in sand.
The effect of spherical air blast on buried pipelines: a laboratory simulation study
Authors: Vivek Padmanabha , Sitharam Thallak G.
Published: June 2017

A new laboratory-scale experimental technique has been developed to study the blast wave effects on buried pipelines caused by an explosion at an altitude. A shock tube is used in this study to generate a blast wave in a controlled and repeatable manner, without the use of any explosives. The blast wave profile generated is characterised by peak reflected pressure and positive phase duration and is represented using tri-nitro-toluene equivalents. Shock tube experiments have been carried out on a reduced-scale pipe model in a sand deposit. The momentum transfer from the blast wave to the sand bed is indicated by the presence of compression stress waves. It is demonstrated from the experiments that the shock tube is an effective and versatile tool for investigating the interactions of blast wave with the buried structures. Using the dimensional analysis procedure, shock tube experimental results are scaled up to predict the real-scale damage imparted to the buried pipes during a spherical air-burst explosion. In addition, a three-dimensional finite-element analysis of the test condition is performed to investigate the fidelity of the scaling laws.
Disinfection ability of hibiscus seeds in water treatment
Authors: Jones Alfred Ndahi , Bridgeman John
Published: June 2017

The disinfecting ability of hibiscus seed proteins against Escherichia coli, total coliforms and faecal coliforms in water treatment was investigated. Hibiscus seeds are widely available as a primary source of protein in tropical countries. Using varying doses of extracts, partial inactivation of faecal coliforms and E. coli was achieved. Hibiscus sabdariffa crude extract (SCE) achieved 67% faecal coliform inactivation whereas Hibiscus cannabinus (kenaf) crude extract (KCE) achieved 57% using dosages of 200 mg/l. Additionally, E. coli were observed to be more sensitive to KCE than SCE, with maximum inactivations of 65% and 60%, respectively. Furthermore, complete bacterial regrowth was witnessed with the extracts after 72 h storage time. However, purified sabdariffa protein (PSP) and purified kenaf protein (PKP) showed complete (100%) bacterial inactivation post-treatment, using a dose of 1·48 mg/l. Additionally, PSP and PKP achieved 92% and 90% turbidity removal, respectively, from a value of 11·9 NTU. Therefore, the use of PSP and PKP in water treatment could improve access to clean water in developing countries.
Assessment and Evaluation Techniques
Authors: Baranovskaya Tatiana , Shaforostova Valentina
Published: June 2017

Assessment and evaluation have always been important; they are linked to language teaching methodology, program outcomes, language teacher competencies, language standards and second language acquisition training. They can serve many different policies and can come in different forms. Assessment and evaluation have always been seen as the responsibility of the specialists, but they have rarely been included as a component in English language teacher (ELT) training. However, the ELT field has been experiencing a major shift in assessment and evaluation with effects on teachers, and learners around the world. It has also been influenced by a major questioning of traditional forms of testing and the underlying psychometric principles of measurement in ELT. Recent studies reveal that the reconceptualization of English language assessment and evaluation provides systematic information about student learning in relation to their performance and contributes to better understanding of their strengths and weaknesses. In many ways ELT has lagged behind the rest of education in the exploration of new theories and assessment and evaluation tools, including self-assessment. This research gap was generated partly because of the lack of integration with mainstream educational theory and practice in many areas of ELT, and partly because of powerful positions of traditional English language tests. The attempt to bridge this gap has lead to the research carried out. The aim of this article is to elaborate different assessment techniques that may better address student learning needs, improve student learning and engage students in self-assessment, including the sequence of steps that could lead to self-assessment. The study shows that the techniques implemented to develop self-assessment enable students to perform well.

To the Problem of Normative Data in Pathopsychological Diagnostics
Authors: Sultanova A. , Ivanova I.
Published: June 2017

The article raises the question of the actuality level of normative data. This kind of data is necessary to compare the results of experimental studies with it, according to the traditions of Russian psychology. It can be assumed that the social changes that took place in the last decades should reflect on the process of forming of thinking and other mental functions. A pilot study for identifying the features of performing of classical pathopsychological techniques by healthy subjects was conducted. The study involved mentally healthy and socially adapted people of 20-39 years old, graduated or undergraduated. We used next several techniques: "Classification of objects", "Pictogram", filling in words missed in the text (Ebbinghaus test), "Interpretation of proverbs". The results of the experiment made it possible to identify two areas in which the changes were most significant. These spheres are emotional-motivational (personality) and thinking. Many subjects were characterized by: a wary-anxious attitude to the experiment, increased emotional - personal attitude to the stimuli material, a decrease in criticality to the results of their activities, neurodynamic disorders, inconsistency of thinking, versatility of thinking, a tendency to resonate, self-centered thinking (according to the authors these features are manifested in the form of "pathopsychology of everyday life" in everyday lifestyle). It is necessary to conduct special large-scale scientific research devoted to this problem.

El regionalismo en la arquitectura religiosa de posguerra en Asturias: el proyecto neoprerrománico para la reconstrucción de la iglesia parroquial de La Felguera, Langreo
Authors: Fernández García Noelia
Published: June 2017

RESUMEN:1Tras el establecimiento de la dictadura en la España de la posguerra, la arquitectura se vio supeditada a sus intereses políticos e ideológicos, hecho que unido al aislamiento del país desembocó en la recuperación de las formas constructivas anteriores y, por ende, de los historicismos. El proceso de reconstrucción de la arquitectura religiosa estuvo marcado, en gran medida, por la línea regionalista o casticista, motivo por el que, en el caso del Principado de Asturias, destaca la recuperación del prerrománico asturiano. El primer proyecto para la reconstrucción de la iglesia parroquial de Santa Eulalia de Turiellos se presenta como el ejemplo más patente del uso del neo-prerrománico para estas arquitecturas, a pesar de no haber llegado a materializarse.PALABRAS CLAVE:Franquismo, reconstrucción, Langreo, La Felguera, José Ramón del Valle Lecue, neoprerrománicoABSTRACT:After the establishment of Franco’s dictatorship in Spain, architecture was strongly controlled by the political and ideological state interests. This fact, joined to the international isolation of the country, led to the recovery of historical styles. Religious architecture reconstruction process was defined, mostly, by regionalisms and this is the reason why asturian pre-romanesque style was recovered in the Princedown of Asturias. The first project made for the reconstruction of Santa Eulalia de Turiellos parish church is a great example of the use given to pre-romanesque style in this architectures, although it wasn’t built finally.KEYWORDS:Franco’s dictatorship, reconstruction, Langreo, La Felguera, José Ramón del Valle Lecue, neopre-romanesque

RESUMEN:El análisis de la relación directa de los términos “estilo jesuítico” y “noster modus” con las teorías arquitectónicas del Humanismo como aglutinante de la llamada arquitectura de los jesuitas es una parte fundamental del trabajo. A partir de esta hipótesis, hemos utilizado la tipología de San Luis de los Franceses, (Sevilla), como ejemplo característico de la funcionalidad, ornato y lenguaje decorativo de la arquitectura jesuítica. Considerada como de las arquitecturas más notables de la Compañía de Jesús, es destacable su planta centrada en forma de cruz griega inscrita en un rectángulo, poco conocida en Sevilla. El diseño de la arquitectura basado en sus propias reglas constructivas ha sido un hito de la historia de arquitectura occidental. Esta forma de proceder respetaba el pensamiento humanista en el que la casa de Dios debía simbolizar la perfección, armonía, belleza e integridad del Creador.PALABRAS CLAVE:Humanismo; Arquitectura jesuítica; Barroco; Perspectiva Lineal; Noster modus.ABSTRACTThe analysis of the direct relationship of the terms “jesuit style” and “noster modus” (our way of proceeding), with the architectural theories of Humanism as a binder of what it is called Jesuit Architecture, it is also a fundamental part of this work. From this hypothesis, we used the typology of St. Louis of the French in Seville, as an example of ornamental and decorative language of Jesuit architecture. This church is considered one of the most remarkable architectures of the Society of Jesus. It is noteworthy its centered floor plan in the shape of a Greek cross inscribed in a rectangle. This is plan is little known in Sevillian Architecture. The design of the architecture based on Jesuitical construction rules has been a milestone in Western architectural history. This way of proceeding respected humanist thinking, in which the household of God was supposed to symbolize perfection, harmony, beauty and integrity of Creator.KEYWORDS:Humanism; Jesuit Architecture; Baroque; Linear Perspective; Noster modus.
Solitary bone cysts in children
Authors: Pozdeev Aleksander P. , Belousova Ekaterina A.
Published: June 2017

Summary. Solitary bone cyst (SBC) is one of the most common childhood pathologies of the skeleton. According to different authors, SBC represents 21 % to 57 % of the benign tumors and tumor processes in the bones of children. SBC usually consists of a single chamber cavitary formation filled with a transparent liquid with a straw colored lining of varying thickness, which consists of connective tissue and single giant cells. There is no consensus on the etiopathogenesis of SBC, and the choice of treatment. There are no clear indications for conservative and surgical treatment of SBC. Some authors are inclined to use puncture (minimally invasive) treatments, while others choose more radical surgical methods. Both methods have the same relapse rate at up to 27 %. In this article, we analyzed the published data on the etiology, pathogenesis, diagnosis, and methods of treatment of SBCs in children.

Published: June 2017

INTRODUCCIÓN: la menarca es un acontecimiento tardío en el desarrollo puberal y constituye el hito más significativo. Se ha descrito un adelanto progresivo en la edad de presentación de la menarca.OBJETIVO: determinar la edad de aparición de la menarca y su relación con la edad de la menarca materna.MATERIAL Y MÉTODOS: estudio retrospectivo, analítico, realizado entre mayo del 2014 y septiembre del 2015. Se estudiaron a niñas que presentaron su menarca con edad ginecológica menor a tres años. Se registró la edad de la menarca, seguro de salud y lugar de residencia de la niña y edad de la menarca de su madre, por el método de recuperación de datos. Se calcularon el índice de masa corporal (IMC) y el IMC/edad–Z score de la niña.RESULTADOS: se incluyeron 250 niñas que presentaron menarca a una edad promedio de 11.6 ± 1.1 años; con un adelanto significativo de un año respecto a la de su madre: 12.6 ± 1.6 años (p < 0.00001). Se observó una correlación negativa estadísticamente significativa entre la edad de la menarca de las niñas y su IMC/edad-Z score (p < 0.00001); se mantuvo independiente del lugar de residencia (p = 0.3903) y del seguro de salud (p = 0.6067).CONCLUSIÓN: en nuestra población, la menarca ocurrió un año antes en promedio en las hijas que en sus madres. Se observó una tendencia a la disminución de la menarca promedio en niñas con aumento del índice de masa corporal. No encontramos asociación entre la edad de la menarca y el nivel socioeconómico o lugar de residencia.

Two themes are discussed: how this novice teacher embraced bilingual teaching whilequestioning practices and policies and how she negotiated contradictionsthrough multiple attempts to redefine her teaching practices. Findings showhow the teacher’s ability to notice framed her possibility to bridge herunderstandings about teaching, her critical pedagogical discourse, and thecontextual contradictory discourses predominant in her school about bilingual education.
Whiter Shade of Pale: Making the Case for Jewish Presence in the Multicultural Classroom
Authors: Rubin Daniel Ian
Published: June 2017

Despite over 4,000 years of persecution, American Jews and antisemitism continue to be overlooked in university multicultural and social justice classroom discussions. This is due to many factors, such as the misconceptions that Jews are solely a religious group, are White and have completely assimilated into American culture, and are economically successful. Jews are a distinctive group in the United States who continue to experience racism and oppression. In order to validate the racism and discrimination of Jews in the United States, university multicultural and social justice programs must begin to discuss the issues pertaining to antisemitism.

Intercalation of Anthraquinone-2-Sulphonate into Magnesium- Aluminum Layered Double Hydroxide and its Calcined Products by Ion Exchange and Memory Effect Properties
Authors: Hussein M.Z.b. , Yahaya A.H. , Ibrahim M. , Tahir M. , Sulimat H.
Published: June 2017

Layered double hydroxide of Mg-Al-nitrate system (LDH) was prepared and its heat-treated products (LDHTs) were obtained by calcining the LDH at 250–750 °C, for 5 hours at atmospheric condition. The LDH and the LDHTs were used as an inorganic host for the intercalation of AQ2 via ion exchange or memory effect property by exposing the LDH and LDHTs in aqueous solution containing an anion, anthraquinone-2-sulfonate (AQ2) for the formation of an organic-inorganic layered nanohybrid materials. X-ray diffractograms showed that the layered structure of LDH collapsed when it was heated at around 350 °C, and an oxide phase, MgAl2O4 appeared. Due to the memory effect property, the regeneration of LDH from LDHT was observed and at the same time the AQ2 was intercalated when LDHT was treated with the aqueous solution containing AQ2. As a result, formation of an organic-inorganic layered nanohybrid material was also observed. Similarly, the same material can be formed by ion exchange of LDH with AQ2. The basal spacing of LDH was found expanded from 8.1 Å to around 20 Å in the resulting nanohybrid. This is to accommodate a bigger size of the AQ2 moiety with specific orientation inside the interlamella of the inorganic layered structure that warrants the layer expansion. Incomplete intercalation and ion exchange process resulted in a mixed LDH and a nanohybrid phase as observed in the PXRD pattern of the resulting material.
E-Preferred Approval Books at the University of Manitoba: A Comparison of Print and Ebook Usage
Authors: Horner Jan C.
Published: June 2017

Abstract

Objective – To compare the usage of print and ebooks received on University of Manitoba’s e-preferred YBP approval plan as well as to examine cost per use for the approval print books and ebooks.

Methods – Usage data was compiled for books received on approval in 2012/2013 to December 31, 2014. Counter reports were used to determine use and non-use of ebooks, while vendor reports from EBL and ebrary were used for the cost per use analysis. Print usage information was drawn from SIRSI and then ALMA when UML switched systems at the beginning of 2014.

Results – Ebooks received more use than p-books overall, but when examined by subject discipline, significant differences could not be found for the “STM” and “Other” categories. With ebooks, university press books tended to be used more than those from other publishers, but the same result was not found for print books. Ebrary ebooks tended to be used more often than EBL, EBSCO, and Wiley ebooks, and single-licence books tended to be somewhat more used than multi-user ones. Cost-per-use data was much lower for print books, though the comparison did not look at staffing costs for each medium.

Conclusions – This study finds that of approval books matching the same profile, ebooks are used more, but print books receive more substantial use. Both formats are needed in a library’s collection. Future comparisons of cost per use should take into account hidden labour costs associated with each medium. Usage studies provide evidence for librarians refining approval plan profiles and for budget managers considering changes to monographic acquisition methods and allocations.

Authors: Kabululu Mujuni Sospeter , Feyissa Tileye , Ndakidemi Patrick Alois
Published: June 2017

Fifty Tanzanian local maize cultivars, seven popularly grown commercial varieties in Tanzania and eleven elite lines from CIMMYT, Nairobi, Kenya were evaluated for agronomic performance. The genotypes were subjected to randomized complete block design at three sites in 2015, both conducted at Arusha region, in Tanzania. The analysis identified highly significant variances among genotypes evaluated and their interactions with environments. The GGE biplot analyses identified the winning genotypes on mean yield and stability. An open pollinated variety (OPV) Situka 1 and an hybrid DH 04 had generally the best performance in terms of grain yield and stability across all three locations. A local cultivar TZA 2793 emerged to be the promising landrace with overall appealing yield and stability performance. The obtained information through this current study may be a good source of new allelic diversity that could be used for developing different important elite maize materials.

The World Energy consumption has been increasing steadily since industrialization, this recent increase is also the major cause for the raise of CO2 concentration in the atmosphere. Fossil fuels play a central role in our energy consumption; actually the CCS technology and their operations in power systems must get a prominent role in reducing total CO2 emissions. An attempt to tackle the problem of solvent based Post Combustion Carbon Capture process optimization requires the availability of a rigorous process model along with a design methodology. During the modeling, much physical and chemical process should be considered in order to get more realistic results, this complexity process addressed as Reactive Separation. This report presents detailed descriptions of the process sections as well as technical documentation for the ASPEN Plus simulations including the design basis, models employed, key assumptions, design parameters, convergence algorithms, concentration and temperature profiles and calculated outputs. The main purpose is to minimize the amount of energy required in the desorption process through the optimum operating condition to the actual CO2 absorption experimental setup. The case of study is on MEA 30wt% in a coal Hired power plant. Electrolytic method is considered; the sensitive analysis was used for the Optimization.

Facing Alzheimer’s disease in the developing countries.
Authors: Marciani Dante J.
Published: June 2017

Aunque el incremento de casos de enfermedad de Alzheimer (EA) en los países desarrollados será limitado, en los países en desarrollo de América Latina, Asia y África será en el año 2050 tres veces el de los países desarrollados. Que ciertas correlaciones entre la EA y factores de riesgo válidas para los países desarrollados no son tan categóricas cuando se aplican a los países en desarrollo, sugiere diferencias en el desarrollo de fármacos para esta enfermedad. Es improbable que, debido al costo de las medicinas de los países industrializados, el tratamiento de la EA sea una prioridad en los países subdesarrollados; por lo tanto, una estrategia más efectiva sería el prevenir o retrasar esta enfermedad. De las opciones, la vacuna contra la EA es la más favorable a pesar de que todos los intentos para producirla han fracasado, resultado de productos desarrollados usando información insuficiente; lo que ha fomentado una opinión negativa de esta vacuna en los círculos científicos. Sin embargo, la información disponible revela que los antígenos de esas vacunas posiblemente indujeron una inmunidad perjudicial y que la respuesta inflamatoria estimulada por varias de esas vacunas agravó el inicio de EA. Además, debido al daño irreversible causado por la EA y la inmunosenescencia, es poco probable que las vacunas terapéuticas tengan valor práctico en el tratamiento de la EA en estado avanzado. Sin embargo, esta información provee bases sólidas para diseñar nuevas vacunas para prevenir o retardar esta enfermedad; información que ha sido ignorada y las vacunas para prevenir la EA, de hecho descartadas. No obstante, ahora hay un mejor conocimiento de los inmunógenos necesarios para inducir una inmunidad protectora y de los adyuvantes requeridos para estimular la producción de anticuerpos protectores e inhibir la inmunidad inflamatoria perjudicial. Considerando las opciones limitadas que tienen los países en desarrollo para controlar la epidemia de EA, sería razonable si estos países colaboraran y usaran los conocimientos disponibles para desarrollar vacunas para prevenir/retrasar la EA. Un avance que produciría beneficios médicos y económicos para América Latina y otras regiones del mundo.

La fistula carótido-cavernosa es una comunicación anómala entre la arteria carótida y el seno cavernoso que provoca un shunt arteriovenoso  patológico y cuyo origen es traumático o espontáneo. Las manifestaciones clínicas están relacionadas con el cambio de dirección del drenaje venoso y del flujo sanguíneo a través de la fístula e incluyen síntomas oculares tales como quemosis, exoftalmos y soplo orbitario, además de manifestaciones neurológicas como infartos venosos y hemorragias intracerebrales. Su presencia se confirma mediante la angiografía por sustracción digital (ASD) y la clasificación generalmente aceptada se basa en la propuesta por Barrow. El tratamiento endovascular ha sido el enfoque terapéutico preferido durante las últimas dos décadas; sin embargo, el tratamiento quirúrgico sigue siendo una opción cuando aquél falla o no está disponible. Se reporta el caso de una paciente de 71 años de edad, con antecedente de traumatismo cráneo-encefálico en la que se diagnósticó fístula carótido-cavernosa izquierda y síntomas neuro-oftalmológicos bilaterales asociados a un infarto venoso a nivel temporal izquierdo. La paciente fue intervenida quirúrgicamente y presentó una evolución clínica favorable.

Culm length (CL) is composed of different elongated internode lengths (EILs) and is closely correlated to the lodging resistance in rice (Oryza sativa L.). The objective of this study was to identify quantitative trait loci (QTLs) stably associated with CL and the first to fourth EIL from panicle base, which were abbreviated as FIL (first), SIL (second), TIL (third), and FOIL (fourth) in japonica rice, respectively. Association mapping was conducted using the genotypes determined by 154 simple sequence repeat markers and the phenotypes in 2010, 2011, and 2015 of 331 japonica rice accessions. The study mapped 6, 5, 15, 2, and 2 QTLs tagged by 22 markers on eight chromosomes and stably associated with CL, FIL, SIL, TIL, and FOIL, respectively. Five QTLs, qCL‐6‐2, qFIL‐6‐5, qSIL‐6‐2, qTIL‐6‐3, and qFOIL‐7‐5, explained the largest phenotypic variance of CL, FIL, SIL, TIL, and FOIL, respectively. RM1340, RM1374, RM281, RM233, and RM225 were stably and specifically associated with CL, FIL, SIL, TIL, and FOIL, respectively. Forty‐three effective alleles were identified. Four and three donors with negative and positive alleles were recommended. There was a highly significant phenotypic difference between accessions with or without effective alleles. These QTLs, associated markers, effective alleles, and their donors could be used to improve CL and specific EIL in japonica rice.

Core Ideas

The α,α'‐dipyridyl dye displayed a ferrous iron detection limit of 0.31mg L−1.

Liquid α,α' dipyridyl dye and indicator test strips exhibited similar reactivity.

Light and heat exposure led to potential α,α'‐dipyridyl dye degradation.

The α,α'‐dipyridyl dye provides a tool for hydric soil and wetland identification.

Chemical dyes, including α,α'‐dipyridyl, can be used to identify ferrous iron in hydric soil studies and aid in conducting wetland delineations. Indicator test strips containing α,α'‐dipyridyl have been developed; however, limited data addresses the reliability of indicator test strips and questions remain regarding potential degradation of α,α'‐dipyridyl in liquid and paper formulations. Laboratory studies found ferrous iron detection limits of 0.31 mg L−1 using both liquid and indicator test strips. The liquid dye and indicator test strips displayed similar reactivity in five soils under simulated field conditions. Results suggest that indicator test strips provide a useful tool for ferrous iron detection across a range of soil conditions. Degradation studies indicate that both liquid dye and indicator strips were impacted by light and heat exposure, with a loss of reactivity observed within as few as 3 d under extreme conditions. Maintaining both liquid dye and indicator strips in cool, dark conditions and testing reactivity with laboratory solutions will ensure the reliability of α,α'‐dipyridyl results.
A semi-analytical method for vibration analysis of thin spherical shells with elastic boundary conditions
Authors: Xie Kun , Chen Meixia , Li Zuhui
Published: June 2017

A semi-analytical method is proposed to analyze both axisymmetric and asymmetric vibrations of thin opened spherical shells with elastic boundary conditions and discontinuity in thickness. To establish the governing equation, the method is involved in dividing the shell into many narrow strips in meridional direction, and those strips are approximately treated as conical ones with uniform thickness. Flügge shell theory is used to describe the motions of strips and displacement functions are expanded as power series. Artificial springs are employed to restrain displacements at edges so that arbitrary boundary conditions can be analyzed. By assembling all continuity conditions of adjacent strips and boundary conditions, the governing equation is established. In numerical results discussion, many comparisons of frequency parameters of present method and those in literature are firstly presented and they illustrate high accuracy and wide application of present method. Furthermore, influences of elastic boundary conditions, open angle, ratio of thickness to radius and thickness discontinuity on natural frequencies of spherical shells are investigated. Results show that meridinoal and circumferential displacements have obvious effects on natural frequencies, and the influence of thickness discontinuity seriously depends on the location of discontinuity.

Vibration-based analysis is the most commonly used technique to monitor the condition of gearboxes. Accurate classification of these vibration signals collected from gearbox is helpful for the gearbox fault diagnosis. In recent years, deep neural networks are becoming a promising tool for fault characteristic mining and intelligent diagnosis of rotating machinery with massive data. In this paper, a study of deep neural networks for fault diagnosis in gearbox is presented. Four classic deep neural networks (Auto-encoders, Restricted Boltzmann Machines, Deep Boltzmann Machines and Deep Belief Networks) are employed as the classifier to classify and identify the fault conditions of gearbox. To sufficiently validate the deep neural networks diagnosis system is highly effective and reliable, herein three types of data sets based on the health condition of two rotating mechanical systems are prepared and tested. Each signal obtained includes the information of several basic gear or bearing faults. Totally 62 data sets are used to test and train the proposed gearbox diagnosis systems. Corresponding to each vibration signal, 256 features from both time and frequency domain are selected as input parameters for deep neural networks. The accuracy achieved indicates that the presented deep neural networks are highly reliable and effective in fault diagnosis of gearbox.

The present paper involves in the estimation and approximation of Eigen values and Eigen vectors of an Elliptical plate with a rectangular cut-out under simply supported boundary condition using Independent coordinate coupling method with an eight term deflection function. The study also investigates the effect of position and size of cut-out with rectangular shape on the natural frequencies of an elliptical plate. The variation of the natural frequencies with the change in position of cut-out along the axes of symmetry and along the radial line is studied. The present method ICCM utilizes independent coordinates separately for plate domain and hole domain. The deflection condition of plate and the hole is equated to derive the relationship between global axes and the local axes. The resulted transformation is useful in deriving the mass and stiffness matrices. The size and position of cut-out have been focused to investigate their effect on the natural frequency of an elliptical plate.
Analysis of blasting vibration wave propagation based on finite element numerical calculation and experimental investigations

Seismic waves created during explosions are transmitted in an outward direction via the surrounding medium, creating a seismic effect that compromises the security of facilities. The energy released during explosions forms dynamic pressure, which creates gas pressure-induced blast waves that cause the ground to vibrate. The damage extent and influence of a blast are dependent on the energy released by the blast shock waves. Blast waves influence the stability of materials. Therefore, controlling vibration hazards is imperative in ensuring material security. This study investigated the effect of explosion-induced vibrations on the surface of a leveled landform. Changes in dynamic load over time were analyzed by conducting numerical simulations and actual onsite experiments. The Multi-Material Arbitrary Lagrangian-Eulerian algorithm were employed to develop a structural model for coupling fluid with solid grids, which was used to analyze the ground acceleration induced by the blasting effect. The results were used to determine the appropriate distance from which vibration reduction, disaster prevention, and safety protection can be achieved.
