Published: October 2017

Introdução: a doença Hipertensiva Específica da Gravidez (DHEG), possui alta prevalência, sendo importante causa de morbidade materna e fetal. A síndrome de Anticorpos Antifosfolipídeos (SAAF) é sabidamente fator de risco para DHEG; porém, em doentes sem diagnóstico prévio de SAAF, poucos estudos são feitos em relação à soroprevalência de anticorpos antifosfolipídeos na DHEG. Objetivos: Estimar, a partir da comparação da positividade de anticorpos antifosfolipídeos entre dois grupos de pacientes, uma possível relação causal entre estes e a presença de doença hipertensiva específica da gravidez. Metodologia: realizamos um estudo observacional, com puérperas diagnosticadas com DHEG, sem diagnóstico prévio de doenças autoimunes ou SAAF, dosando-se os títulos de anticorpos anticardiolipina, anti-beta2glicoproteina1 e anticoagulante lúpico em comparação com puérperas sem patologias em um hospital de ensino terciário. Resultados: Foram avaliadas 69 pacientes, sendo 60 pacientes com DHEG em seu espectro de gravidade, 9 pacientes em grupo de controle normal, sendo observada que a incidência de algum AFL foi 31,6% no grupo de casos e 0% no grupo controle (p=0,00). Conclusão: concluímos que um número importante de puérperas possuem, durante a DHEG, níveis elevados de anticorpos antifosfolipídeos. Acreditamos que essas doentes se beneficiarão de novo screening para SAAF após 12 semanas, com o objetivo de, em gravidez futura, evitar novos eventos mórbidos.

Authors: Farias Luis Arthur Brasil Gadelha , Pires Neto Roberto da Justa
Published: October 2017

A 81-years-old caucasian man presented with acute burning pain in external auricular region and inside the auditory canal of right ear, associated with vesicular lesions on face, jugal and lingual mucosa. Physical examination revealed vesicular lesions in external auricular region and inside the auditory canal. Red blood cell count, leukocytes and platelets were normal. Presented HIV-1 and 2 both negative. Patient denied previous history of Diabetes and Hypertension. Treatment was initiated with Ceftriaxone 2g, Acyclovir 250mg, Prednisone 60mg and Bicarbonate Water for rinsing. After eight days of hospitalization, patient reported hearing loss in the right ear, chewing difficulty and mild pain in face. Auditory hearing loss and hypoacusis may suggest involvement of vestibulocochlear nerve. Figure 1 shows cicatricial crusted lesions following trigeminal nerve mandibular branch trajetory. Figure 2 reveals cicatricial crusted lesions following trigeminal nerve maxilar branch, trigeminal branch and erythematous scarring lesions in tongue, hypoglossal nerve region. Figure 3 reveals small crusted lesions following the trigeminal ophthalmic branch. Herpes zoster is caused by Varicella zoster virus (VZV) reactivation in individuals who had Varicella in childhood or who were vaccinated. The presence of more than one dermatome affected is rare in immunocompetent individuals, being more prevalent in immunosuppressed individuals such as HIV positive and transplanted patients.1Disseminated herpes zoster can occur in any immunocompetent patient but predominates in elderly due to factors that compromise cellular immune response. 2,3
Endoplasmic reticulum-to-Golgi transitions upon herpes virus infection
Authors: Wild Peter , Kaech Andres , Schraner Elisabeth M. , Walser Ladina , Ackermann Mathias
Published: October 2017

Background: Herpesvirus capsids are assembled in the nucleus before they are translocated to the perinuclear space by budding, acquiring tegument and envelope, or releasing to the cytoplasm in a “naked” state via impaired nuclear envelope. One model proposes that envelopment, “de-envelopment” and “re-envelopment” are essential steps for production of infectious virus. Glycoproteins gB/gH were reported to be essential for de-envelopment, by fusion of the “primary” envelope with the outer nuclear membrane. Yet, a high proportion of enveloped virions generated from genomes with deleted gB/gH were found in the cytoplasm and extracellular space, suggesting the existence of an alternative exit route.

Methods: We investigated the relatedness between the nuclear envelope and membranes of the endoplasmic reticulum and Golgi complex, in cells infected with either herpes simplex virus 1 (HSV-1) or a Us3 deletion mutant thereof, or with bovine herpesvirus 1 (BoHV-1) by transmission and scanning electron microscopy, employing freezing technique protocols that lead to improved spatial and temporal resolution.

Results: Scanning electron microscopy showed the Golgi complex as a compact entity in a juxtanuclear position covered by a membrane on thecisface. Transmission electron microscopy revealed that Golgi membranes merge with membranes of the endoplasmic reticulum forming an entity with the perinuclear space. All compartments contained enveloped virions. After treatment with brefeldin A, HSV-1 virions aggregated in the perinuclear space and endoplasmic reticulum, while infectious progeny virus was still produced.

Conclusions: The data strongly suggest that virions are intraluminally transported from the perinuclear space via Golgi complex-endoplasmic reticulum transitions into Golgi cisternae for packaging into transport vacuoles. Furthermore, virions derived by budding at nuclear membranes are infective as has been shown for HSV-1 Us3 deletion mutants, which almost entirely accumulate in the perinuclear space. Therefore, de-envelopment followed by re-envelopment is not essential for production of infective progeny virus.
ВОЗНАГРАЖДЕНИЕ АВТОРУ ЗА СОЗДАНИЕ И ИСПОЛЬЗОВАНИЕ СЛУЖЕБНОГО РЕЗУЛЬТАТА ИНТЕЛЛЕКТУАЛЬНОЙ ДЕЯТЕЛЬНОСТИ: ИСТОРИКО-ФИЛОСОФСКИЙ АСПЕКТ
Authors: Vilmova Tatyana Aleksandrovna
Published: October 2017

В гражданском законодательстве в области регулирования правоотношений между автором-работником и работодателем по поводу создания и использования служебных результатов интеллектуальной деятельности (РИД) существует ряд неразрешенных вопросов. Один из которых касается размера, порядка определения и уплаты вознаграждения автору произведения. Не смотря на наличие на сегодняшний день достаточного количества законных и подзаконных актов (которые отсылают друг к другу, но не дают ответы на поставленные вопросы), остается нерешенным вопрос о юридической природе вознаграждения, как материального блага, выплачиваемого автору. Ввиду чего работодатели или третьи лица часто злоупотребляют законодательными пробелами с целью заполучения объекта творческой труда без выплаты работнику по справедливости причитающегося блага.После создания служебного РИД встает вопрос о выплате или о не выплате работнику вознаграждения. Ведь для работодателя будет выгодным признать объект, созданный мыслительным путем, выполненный работником в рамках трудовой деятельности или конкретного задания работодателя. При чем, такое задание не должно выходить за рамки должностной инструкции. Поскольку вознаграждение, как правило, будет невелико. А что делать, когда объект создан за рамками трудовой функции? Каков будет справедливые и законный размер вознаграждения? Поэтому именно такие понятия как «трудовая обязанность» и «конкретное задание работодателя» становятся в практике камнем преткновения. И при решении поставленных вопросов, авторы часто начинают поиск ответов с философских истоков зарождения вознаграждения за творческих труд, используя методы сравнительного анализа, историко-правовые способы и даже философские учения древних мыслителей.Целью научной стати является разрешение проблемы при взыскании авторами служебных результатов интеллектуальной деятельности вознаграждения за созданные и использованные объекты интеллектуальной собственности с применением категорий «справедливости», «законности», «соразмерности», имеющих философский генезис.Методами научного исследования выступают: анализ действующего гражданского законодательства в области защиты авторских прав, сравнительно-исторический подход к изучению становления и развития законодательства в сфере интеллектуальной собственности, синтез знаний, сформулированных древнегреческими и средневековыми мыслителями, с целью рассмотрения выплаты вознаграждения автору через призму распределения благ в политически-организованном обществе.Область применения результатов: данные знания применимы в области защиты прав авторов своих субъективных прав на результаты интеллектуальной деятельности, созданные в рамках трудовой обязанности или конкретного задания работодателя.

Introduction
Authors: O’Leary Alan , Ghosh Shoba Venkatesh
Published: October 2017

This special issue is intended to take forward a sympathetic reconceptualization of the pleasures of popular film and of related forms such as soap operas and pornography. The five articles contained in the special issue vary in length and scope, and are followed by a response piece from a senior scholar. We hope that the dialogic mix of case studies and theoretical or survey approaches brings a liveliness to the treatment of pleasure, and indeed that it encapsulates our sense that pleasure retains a conceptual elusiveness, no matter how often discussed (or experienced). We acknowledge the elusiveness in this introduction, which we have cast in the form of a dialogue to acknowledge our individual motivations and to indicate the different academic and cultural contexts in which we, the two editors, work. We jointly describe the content of the articles at the end of the dialogue.
Beyond the pleasure principle: Exploring the limits of a pervasive term
Authors: Bayman Louis
Published: October 2017

This article aims to discuss pleasure as a way of understanding film. I do not seek to judge the correctness, political or otherwise, of certain pleasures, or to offer any overarching theory of pleasure. Instead I investigate what film scholars talk about when we talk about pleasure. Understanding pleasure more as an attitude to film spectatorship rather than an object in and of itself, I consider the importance not solely of the rational pursuit of prima facie pleasures but also of more enigmatic emotional needs relating to intimacy, pain and the confirmation of shared values. Separating cinematic pleasure from any necessary association with positivity, I caution against the potential for pleasure to be instrumentalized as part of a neo-liberal ethic of happiness.
Queer effractions: Male to male porn and the pursuit of self-shattering
Authors: Champagne John
Published: October 2017

The changing status of HIV disease has significantly influenced cinematic representations of sex between men and the pleasures these representations offer. This article examines two different cinematic explorations of ‘risky’ sex: one, the documentary Chemsex, on the combining of sex and drugs; the other, raw (condomless) porn – including auto-porn, porn made by the people engaged in the sex being filmed. It argues that, because the sexual is the site of so much ambivalence, its representation engages sensibilities far more nuanced than the term pleasure suggests.
Response: It has been a pleasure
Authors: Barker Martin
Published: October 2017

This response is a commentary that reflects upon a certain shared characteristic in the five essays in this Section: that is, a shared sense that the ways in which ‘pleasure’ has been understood and theorized in film studies are not adequate to the particular cases examined in each essay. This commentary explores the issues addressed, beginning with a consideration of the long list of words available in English (and in other languages) for describing positive feelings. Their subtle differences and nuances reflect the complex ways in which people ordinarily understand and describe their enjoyments of films. These are contrasted with the restrictive ways in which ‘pleasure’ is conceived within three major film theoretic traditions: psychoanalysis, cognitive film theory and phenomenology. The article argues, finally, for wider attention to the ways in which audience research can take us beyond the ways of understanding ‘pleasure’ currently on offer within film theory.

Published: October 2017

Increase in consumption of conventional plastics lead to environmental problems. Therefore, some efforts are needed to overcome it, one of them by using bioplastics. However, in Indonesia, companies engaged in bioplastics sector are still rarely found. Without the readiness of the bioplastics industry in Indonesia, development of bioplastics which ends to solve environmental problems cannot be realized. Through Socio-Technical Systems (STS) approach with Multi Level Perspective framework, this Papper analyze the dynamics of the transition of bioplastics in Indonesia. The results show the presence of pressure from landscape to underdeveloped niche, regime actors would give respond by modifying path development from its innovation activities. In other words, bioplastics in Indonesia has not yet experiencing a transition to replace conventional plastics. Precisely, technology in regime level experiencing change by developing additive plastic. However, there are several things that hinder further development of the niche, which include the high price of bioplastics and implementation of regulations related with incentives and disincentives and there is no coordination and shared vision between actor in niche level.

Bound-Constrained Multiple-Image Least-Squares Matching for Multiple-Resolution Images
Authors: Hu Han , Wu Bo
Published: October 2017

Satellite images from multiple sources with different resolutions are currently able to observe the same region. Reliable image matching between these images is the first step in their integrated use. Image matching of multiple-resolution images is not trivial because of the large geometric
differences among the images, which can cause failure of matching and losses of matching accuracy. This paper presents a bound-constrained, multiple-image, least-squares matching (LSM) method that extends the classical LSM in two ways for
better performance. First, the a priori metadata of the images, including the geo-referencing and scale information, are used for initial matching and to provide bound constraints in the LSM to improve its stability. Second, multiple images are matched in a single
optimization rather than the traditional pairwise matching. This brings additional observations in the least-squares optimization, which makes the matching aware of both larger and local context and improves matching quality even with inaccurate initializations for high resolution images.
Experimental analysis using multiple-source satellite images with multiple resolutions collected on Mars and in Hong Kong reveals that the proposed method is capable of obtaining reliable multiple-fold matches effectively, even in challenging cases with resolution differences as much as 20-fold.
The method proposed in this paper has significance for the synergistic use of multiple-source satellite images in various applications.
Thematic Accuracy of Agriculture in Land Cover Layers of Select Virginia Counties
Authors: Kokkinidis Ioannis , Hodges Steven C. , Wynne Randolph H.
Published: October 2017

NLCD and NASS CDL are freely available moderate resolution land cover datasets, but their accuracies vary widely and are untested for agricultural land in Virginia. We performed validation through aerial photointerpretation of agriculture
at the field level, using cadastral parcels as proxies for fields, over Albemarle, Charles City, Chesterfield, and Henrico Counties for NLCD 1992, 2001, 2006 and CDL 2002, 2008, 2009, 2010, and 2011. The extent of agricultural land remained
generally stable over 19 years but is generally overestimated by the datasets in all four counties, ranging from 70.06 percent to 697.48 percent of validation layer extent. Extent of agricultural land in our validation layer also differed from the Census of Agriculture, likely due to differing
definition. Comparison of layer pairs on extent of agricultural land mostly reveals classification artifacts rather than change. The limited extent of agriculture and mixed land cover characteristics of the region suggest the use of multitemporal data to extract agricultural land cover.
A Geometric Correspondence Feature Based-Mismatch Removal in Vision Based-Mapping and Navigation
Authors: Li Zeyu , Wang Jinling , Toth Charles
Published: October 2017

Images with large-area repetitive texture, significant viewpoint, and illumination changes as well as occlusions often induce high-percentage keypoint mismatches, affecting the performance of vision-based mapping and navigation. Traditional methods for mismatch elimination tend to fail
when the percentage of mismatches is high. In order to remove mismatches effectively, a new geometry-based approach is proposed in this paper, where Geometric Correspondence Feature (GCF) is used to represent the tentative correspondence. Based on the clustering
property of GCFs from correct matches, a new clustering algorithm is developed to identify the cluster formed by the correct matches. With the defined quality factor calculated from the identified cluster, a Progressive Sample Consensus (PROSAC)
process integrated with hyperplane-model is employed to further eliminate mismatches. Extensive experiments based on both simulated and real images in indoor and outdoor environments have demonstrated that the proposed approach can significantly improve the performance of mismatch elimination
in the presence of high-percentage mismatches.
Registration of Images To Lidar and GIS Data Without Establishing Explicit Correspondences
Authors: Barsai Gabor , Yilmaz Alper , Nagarajan Sudhagar , Srestasathiern Panu
Published: October 2017

Recovering the camera orientation is a fundamental problem in photogrammetry for precision 3D recovery, orthophoto generation, and image registration. In this paper, we achieve this goal by fusing the image information with information extracted from different modalities, including
lidar and GIS. In contrast to other approaches, which require feature correspondences, our approach exploits edges across the modalities without the necessity to explicitly establish correspondences. In the proposed approach, extracted edges from different modalities
are not required to have analytical forms. This flexibility is achieved by minimizing a new cost function using a Bayesian approach, which takes the Euclidean distances between the projected edges extracted from the other data source and the edges extracted from the reference image as its
random variable. The proposed formulation minimizes the overall distances between the sets of edges iteratively, such that the end product results in the correct camera parameters for the reference image as well as matching features across the modalities. The initial solution can be obtained
from GPS/IMU data. The formulation is shown to successfully handle noise and missing observations in edges. Point matching methods may fail for oblique images, especially high oblique images. We eliminate the requirement for exact point-to-point matching. The feasibility
of the method is experimented with nadir and oblique images.
Morfologia Construcional e alguns desafios para a análise de dados históricos da língua portuguesa
Authors: Simões Neto Natival Almeida
Published: October 2017

A Morfologia Construcional é um modelo proposto pelo linguista holandês Geert Booij (2010, 2014), e que tem despontado nas análises morfológicas, dentro de uma perspectiva mais semântica, o que o aproxima de alguns pressupostos teóricos da Linguística Cognitiva. Autores brasileiros, como Soledade (2013) e Gonçalves & Almeida (2014), fizeram aplicações do modelo booijiano para a língua portuguesa, salientando que, apesar de alguns avanços, há questões que precisam ser aprimoradas. O artigo que ora se apresenta segue os passos dessas leituras críticas anteriores, a que se somam as observações de Simões Neto & Soledade (2015) e Soledade (2016a, 2016b, ambas no prelo), reforçando que há muitos desafios no tratamento de dados do português, sobretudo nas questões relativas à Linguística Histórica, tanto no sentido da mudança linguística, quanto para a descrição/interpretação do português arcaico.
“Filha do leiteiro”
Authors: Albuquerque Rodrigo
Published: October 2017

A interação humana prevê, a todo instante, a negociação de sentidos entre os interagentes, a partir de suas enunci(ações). Estes, por sua vez, nem sempre revelam seus sentidos na superfície dos enunciados, o que demanda, assim, um exercício inferencial frente às ações do outro. Em relação a encontros interculturais, tal propriedade se torna ainda mais acentuada, em virtude das (possíveis) distintas convenções socioculturais. Este estudo visa a analisar como a professora de português brasileiro e as colaboradoras do estudo (colombianas) negociam, por meio de pistas de contextualização linguísticas e extralinguísticas, um enunciado irônico. Para a geração de dados, contamos com a participação da professora do curso e de duas estudantes (Laudiel e Mercedes), que permitiram o registro das imagens e se comprometeram com o visionamento das próprias ações e a reflexividade acerca destas. Por fim, constatamos que o enunciado irônico “filha do leiteiro”, proferido pela professora, foi adequadamente processado por Mercedes e pelos demais estudantes, com exceção de Laudiel, que sinalizou essa dificuldade com pistas de natureza não verbal e com posterior relato. O estudo de pistas de contextualização torna-se fundamental na prevenção de ruídos interacionais, provenientes da não partilha de sentido entre sujeitos de culturas distintas.

Buscando compreender as relações que levaram a figura controversa do Anonymous à posição de autor, recorreu-se aos conceitos de autoria, de memória e de narrativa transmídia para fundamentar a análise de três excertos aqui expostos. Neles, apontaremos como a dinâmica entre memória e mídia possibilitou a construção de diversas representações do Anonymous, formando uma complexa rede que sustentou sua legitimidade e o materializou como pilar de sustentação da verdade em um momento histórico tão turbulento.
Processos metonímicos e interpretação
Authors: Miki Yoshioka Jenny , Silva dos Santos Odair José
Published: October 2017

Como matéria do pensamento e veículo de comunicação, a linguagem nos traz conceitos que, conforme Lakoff e Johnson (1980) apontam, estruturam a forma como percebemos, como transitamos no mundo, na realidade que nos cerca, e como nos relacionamos com o outro. Portanto, ao estabelecer um diálogo entre Linguística e Literatura, este artigo tem o objetivo de fazer uma análise acerca dos processos metonímicos presentes no conto, Olhar, de Rubem Fonseca, interpretando e realizando leituras possíveis. O trabalho partiu dos estudos de Feltes (2007), Silva (1997) e Martelotta e Palomanes (2008) referentes à Linguística Cognitiva, dando enfoque à metonímia com Lakoff e Johnson (1980) e Radden e Kövecses (1999). Como resultado, constatou-se que a forma como pensamos, as nossas experiências e vivências diárias são questões intimamente ligadas não só à metáfora, mas, especialmente, à metonímia, por se caracterizar como um processo primário que nos permite definir um elemento por sua relação com outro. Assim, visto como mais do que um simples recurso poético ou retórico, a metonímia ultrapassa a questão de linguagem para se situar no social, tornando-se um dos meios pelos quais interagimos com o outro, como percebemos o mundo e, o mais importante, o significamos.
Variabilidade e estabilidade na produção de sinais da Libras
Authors: Xavier André Nogueira , Barbosa Felipe Venâncio
Published: October 2017

Semelhantemente às línguas orais, a realização concreta de palavras nas línguas sinalizadas é suscetível à variação intra e inter-sujeito. Objetivando ilustrar esse fenômeno na língua brasileira de sinais (Libras), o presente artigo reporta a análise de três produções de seis itens lexicais dessa língua por 12 sinalizantes surdos da cidade de São Paulo. Os resultados mostram que, apesar da variabilidade em alguns parâmetros articulatórios, as diferentes produções desses sinais exibem alguma estabilidade. Tal fato deve garantir a percepção destas como diferentes realizações de uma mesma palavra e não como realizações de palavras distintas.

O estudo do léxico de um determinado recorte geográfico possibilita o registro da herança sociocultural de uma comunidade e do patrimônio linguístico de seus antepassados, que podem ou não se manter vigentes nos discursos mais atuais. O objetivo deste trabalho foi colher o maior número de Expressões Idiomáticas (EI) – preferencialmente faladas e reconhecidas por cidadãos de idade mais avançada – a fim de contribuir para a preservação da riqueza e da singularidade linguística do povo eloiense. Esse estudo mostra uma maneira de manter viva e registrada parte da afortunada herança sociocultural do município, o que só faz comprovar a mutabilidade do léxico por causa da cultura – mutabilidade esta que é percebida na interação social, que se utiliza de um conjunto de palavras e expressões comuns a uma determinada comunidade linguística.

Performance evaluation of existing sunshine-based computing models for estimating global solar radiation at Lagos, Nigeria
Authors: Nwokolo Samuel , Ogbulezie Julie
Published: October 2017

Several empirical models have been fitted in literature for estimating global solar radiation across the globe in order to produce global solar radiation data and also as a baseline for further scientific and environmental research without the substantial cost of instrumental network that would otherwise be needed. However, peers and researchers have reported that the most commonly employed parameter for predicting global solar radiation is sunshine duration as a result of its availability and simplicity in course of measurement globally. In this research, the author considered the performance of 63 sunshine-based models for the prediction of global solar radiation at Lagos, Nigeria. Numerous models are found unreliable for use in this location, and others vary in performance. On the whole, the best model was identified due to its values of statistical indicators.
O desempenho da investigação em gestão em Portugal: Algumas causas e consequências
Authors: Pinheiro Margarida M.
Published: October 2017

Motivados pela revisão da literatura em torno das questões da qualidade, da investigação, do reconhecimento académico e da atividade docente, o objetivo deste estudo é o de identificar causas e consequências do desempenho da investigação em gestão que é feita nas universidades portuguesas. A análise empírica tem por base as fichas curriculares dos docentes submetidas, obrigatoriamente, à Agência Nacional de Avaliação e Acreditação do Ensino Superior. Os dados dizem respeito ao, à data, único censo nacional de acreditação de cursos. Regressão logística, análise de clusters e optimal scalingsão os métodos utilizados no tratamento empírico da informação. O estudo parece confirmar o que já era apontado por alguns autores de que quem faz investigação tende a conseguir uma maior promoção académica, quer porque atinge categorias profissionais mais elevadas, quer porque obtém graus académicos mais avançados ou vínculos contratuais mais estáveis. Contrariamente, a carga horária não se apresenta como fator capaz de influenciar a investigação que é realizada. De salientar, é a clara ausência de contributo da idade, do género, da internacionalização, da experiência profissional ou da endogamia na produção da investigação científica.
Una dimensión real con vida propia: el espacio-tiempo mítico y su relación con la construcción histórica
Authors: López Saco Julio
Published: October 2017

El espacio del mito se revela como formador de imágenes significativas. En él el ser humano es capaz de relacionarse afectivamente con el mundo. Es un espacio imaginario, transcultural e implicativo (no acumulativo como el de la historia), y posee una realidad vivenciable, con una dimensión existencial. Naturalmente, es independiente del espacio geográfico y del contemplado por la física. El espacio mítico es plural: son espacios cualitativamente análogos, no pensados, pero si experimentados. En forma de células aisladas se interrelacionan, sin embargo, entre sí. El tiempo mítico, por su parte, es prístino y fundacional. Es una temporalidad no explicativa fundamentada en simultaneidades, que es presentificadora, pues en el momento en que el mito es contado se hace actual y se lleva a cabo, en una suerte de permanencia todo-temporal. Por tanto, no se puede calificar de duración, sino como una actualización.
El Amaru como emblema de los Incas del Cusco (siglos XVI - XVII)
Authors: Gentile Margarita E.
Published: October 2017

Este artículo aporta a los estudios andinos de convergencia de creencias prehispánicas y europeas el estudio y análisis de dos casos, su continuidad y adaptación en espacio y tiempo. El tema central es la frontera Este de los Andes durante el Tahuantinsuyu, graficada mediante las boas que poblaban esa región. Los constantes intentos de paliar los cataclismos –que se creía producían con sus movimientos– datan de varios siglos antes que Pachacutec refundase el Cusco y el éxito de las tecnologías implementadas cada vez (Chavín, Tiwanaku, Inka y sus epígonos) dejaron su marca en la línea del tiempo prehispánico.
El posicionamiento de la revista El Renacimiento (1847) en el debate arquitectónico entre clasicismo y romanticismo en la España isabelina
Authors: Álvarez Rodríguez María Victoria
Published: October 2017

La Europa decimonónica asistió al surgimiento de una de las aportaciones más novedosas y originales al campo de la historiografía artística contemporánea: las publicaciones periódicas en las que se abordaba el estudio de las Bellas Artes desde una perspectiva bastante alejada de la seriedad característica de las academias. El caso español no fue una excepción en este sentido, aunque hubo que esperar hasta el reinado de Isabel II (1806-1878) para que la recién conquistada libertad de prensa permitiera la aparición de publicaciones de este tipo. En algunos casos estaban estrechamente relacionadas con la defensa de los ideales románticos, mientras que en otros tenían como finalidad servir de entretenimiento al gran público sin comprometerse con ninguna ideología. Y entre las más interesantes que vieron la luz durante el reinado isabelino, El Renacimiento (1847) posee una especial relevancia tanto por su preciosismo como por la seriedad con la que trató la cuestión artística. En el presente estudio nos centraremos en el análisis de los artículos publicados en ella sobre el debate entre clasicismo y romanticismo que estaba teniendo lugar en España por aquel entonces, comparando las opiniones de sus redactores a este respecto y las razones por las cuales poseían posicionamientos ciertamente diferentes.

Cetuximab is a chimeric monoclonal antibody that acts as a competitive antagonist, by binding to EGFR. This cell signalling pathways regulates tumor progression. The oral squamous cell carcinoma undergoes to regional spreading and distant metastasis. This study aimed to evaluate the effect of treatment with Cetuximab on cell migration and invasion in OSCC cells, by using the SCC-4 cell line. Cell migration and cell invasion assay were performed and actin cytoskeleton of control and treated with Cetuximab cells were evaluated. Differences were considered significant when p<0.05.Cetuximab inhibited the migration of SCC-4 cells at three concentrations: 1 µg/mL, 50 µg/mL and 100 µg/mL (p<0.0001) in a dose-dependent manner. The number of SCC-4 treated cells with 1 Î¼g/mL that migrated through the membrane was statistically different from 50 Î¼g/mL (p<0.001) and 100 Î¼g/mL (p<0.0001), and between 50 Î¼g/mL and 100 Î¼g/mL (p<0.01). Cetuximab 50 Î¼g/mL inhibited cell invasion through the MatrigelTM compared with SCC-4 control cells (p<0.01). Cetuximab 50 Î¼g/mL affected the organization of the actin cytoskeleton. Cetuximab has an inhibitory effect on actin cytoskeleton organization, cell migration and invasion, suggesting that Cetuximab treatment can be important to avoid oral squamous cell carcinoma metastasis.

β-galactosidase is an enzyme with hydrolytic and transgalactosylation activity. The origin of the enzyme dictates the balance between both activities. Industrially used β-galactosidases are obtained with recombinant production from filamentus funghi Aspergillus sp. and yeasts Kluyveromyces sp. Recently thermostabile β-galactosidases have been subject of many research. The enzyme can be industrially used in free or immobilized form. Immobilization often provides better stability, reusability and lower expenses. Application of β-galactosidase is most common in food processing and nutrition, it is also used in medicine and ecology. Hydrolytic activity of the enzyme has long been used for reducing lactose content in milk, while transgalactosylitic activity is used for synthesis of products such as galactooligosaccharides, lactosucrose and others. The latter have a great potential in food industry for obtaining products with reduced lactose content and increasing of nutritional value by adding dietetic fibers such as galactooligosaccharides. Despite the potential it is vital that reaction mechanisms become better understood and optimization is in place in order to reach the usability of this enzyme at industrial level.

A special Slag-Prop Cu database has been developed to archive data from laboratory and industrial tests related to post-reduction slags. In order to enrich the data areas, it was decided to design a system for measuring the temperature of the liquid slag and its viscosity. Objectives of research work are to gather information on the properties of post-slags such as the temperature of liquid slag and its viscosity. The discussed issues are especially important in the foundry practice. Designed research stand and using of database applications can greatly facilitate the work of metallurgists, foundrymen, technologists and scientists. The viscosity measurement was developed and presented earlier. The author’s analytical methodology was supplemented by a thyristor measuring system (described in the article). The system temperature measurement can be performed simultaneously in 3 ways to reduce the measurement error. Measurement of the voltage mV - using the Seebeck effect can be measured throughout the entire range of thermocouple resistance, up to 1300 °C. Direct temperature measurement °C - measurement only below 1000 °C. Additional measurement - the measurement can also be read from the pyrometer set above the bath. The temperature and the reading frequency depend on the device itself. The principle of measurement is that in a molten metal / slag crucible, we put a N-type thermocouple. The thermocouples are hung by means of a tripod above the crucible and placed in a crucible. The thermocouple is connected to a compensating line dedicated to this type of thermocouple. The cable is in turn connected to a special multimeter that has the ability to connect to a computer and upload results. Temperature measurement can be performed simultaneously in 3 ways to reduce the measurement error. The Sn-Pb alloy has been subjected to testing for proper operation of the device. In this foot should be observed the supercooling of the liquid, which initiates the crystallization process and in which latent heat begins to exude raising the temperature until the coagulation temperature is reached.
Effect of Soft Annealing Treatment on Impact Strength and Hardness of the EN AC-AlSi11 Alloy
Authors: Jarco A.
Published: October 2017

The paper presents research on the effects of soft annealing parameters on a change of the impact strength KC and Brinell hardness (HB) of the EN AC-AlSi11 alloy. The research has been performed according to the trivalent testing plan for two input parameters – temperature in the range between 280°C and 370°C and time in the range between 2 and 8 hours. The application of such heat treatment improves the plasticity of the investigated alloy. The improvement of the impact strength KC by 71% and the decrease of the hardness HB by 20% was achieved for the soft annealing treatment conducted at a temperature 370°C for 8 hours, compared to the alloy without the heat treatment. A change of the form of eutectic silicon precipitations which underwent refinement, coagulation and partial rounding, had a direct effect on the hardness HB and impact strength KC. The results obtained were used to prepare space plots enabling the temperature and time for soft annealing treatment to be selected with reference to the obtained impact strength KC and hardness HB of the alloy with the heat treatment.

Published: October 2017

The paper presents the results of research of impact strength of aluminum alloy EN AC-44200 based composite materials reinforced with alumina particles. The research was carried out applying the materials produced by the pressure infiltration method of ceramic preforms made of Al2O3particles of 3-6μm with the liquid EN AC-44200 Al alloy. The research was aimed at determining the composite resistance to dynamic loads, taking into account the volume of reinforcing particles (from 10 to 40% by volume) at an ambient of 23°C and at elevated temperatures to a maximum of 300°C. The results of this study were referred to the unreinforced matrix EN AC-44200 and to its hardness and tensile strength. Based on microscopic studies, an analysis and description of crack mechanics of the tested materials were performed. Structural analysis of a fracture surface, material structures under the crack surfaces of the matrix and cracking of the reinforcing particles were performed.
Effect of Annealing on Nature of Corrosion Damages of Medium-nickel Austenitic Cast Iron
Authors: Medyński D. , Janus A. , Chęcmanowski J.
Published: October 2017

Within the presented research, effect of annealing on nature of corrosion damages of medium-nickel austenitic nodular cast iron castings, containing 5.5% to 10.3% Ni, was determined. Concentration of nickel, lower than in the Ni-Resist cast iron, was compensated with additions of other austenite-stabilising elements (manganese and copper). In consequence, raw castings with austenitic matrix structure and gravimetrically measured corrosion resistance increasing along with nickel equivalent value EquNi were obtained. Annealing of raw castings, aimed at obtaining nearly equilibrium structures, led to partial austenite-to-martensite transformation in the alloys with EquNi value of ca. 16%. However, corrosion resistance of the annealed alloys did not decrease in comparison to raw castings. Annealing of castings with EquNi value above 18% did not cause any structural changes, but resulted in higher corrosion resistance demonstrated by smaller depth of corrosion pits.
Repairs of Damaged Castings Made of Graphitic Cast Iron by Means of Brazing

Published: October 2017

The article summarizes the theoretical knowledge from the field of brazing of graphitic cast iron, especially by means of conventional flame brazing using a filler metal based on CuZn (CuZn40SnSi – brass alloy). The experimental part of the thesis presents the results of performance assessment of brazed joints on other than CuZn basis using silicone (CuSi3Mn1) or aluminium bronze (CuAl10Fe). TIG electrical arc was used as a source of heat to melt these filler materials. The results show satisfactory brazed joints with a CuAl10Fe filler metal, while pre-heating is not necessary, which favours this method greatly while repairing sizeable castings. The technological procedure recommends the use of AC current with an increased frequency and a modified balance between positive and negative electric arc polarity to focus the heat on a filler metal without melting the base material. The suitability of the joint is evaluated on the basis of visual inspection, mechanic and metallographic testing.
Long-term Effects of Relative Humidity on Properties of Microwave Hardened Moulding Sand with Sodium Silicate
Authors: Stachowicz M. , Granat K.
Published: October 2017

Moulding sands containing sodium silicate (water-glass) belong to the group of porous mixture with low resistance to increased humidity. Thanks to hydrophilic properties of hardened or even overheated binder, possible is application of effective methods of hydrous reclamation consisting in its secondary hydration. For the same reason (hydrophilia of the binder), moulds and foundry cores made of high-silica moulding sands with sodium silicate are susceptible to the action of components of atmospheric air, including the contained steam. This paper presents results of a research on the effect of (relative) humidity on mechanical and technological properties of microwave-hardened moulding mixtures. Specimens of the moulding sand containing 1.5 wt% of sodium water-glass with module 2.5 were subjected, in a laboratory climatic chamber, to long-term action of steam contained in the chamber atmosphere. Concentration of water in atmospheric air was stabilized for 28 days (672 h) according to the relative humidity parameter that was ca. 40%, 60% and 80% at constant temperature 20 °C. In three cycles of the examinations, the specimens were taken out from the chamber every 7 days (168 h) and their mechanical and technological parameters were determined. It was found on the grounds of laboratory measurements that moulds and cores hardened with microwaves are susceptible to action of atmospheric air and presence of water (as steam) intensifies action of the air components on glassy film of sodium silicate. Microwave-hardened moulding sands containing sodium silicate may be stored on a long-term basis in strictly determined atmospheric conditions only, at reduced humidity. In spite of a negative effect of steam contained in the air, the examined moulding mixtures maintain a part of their mechanical and technological properties, so the moulds and foundry cores stored in specified, controlled conditions could be still used in manufacture.
