Strategies for success as an industrial chemist
Authors: Ribes Carolyn
Published: December 2018

There are multiple factors that contribute to the success of an industrial chemist. In addition to technical knowledge, business acumen and interprofessional skills are required for growth and advancement. The technical expertise that is developed through formal training cannot stagnate; continuous learning is required to remain relevant and drive innovation. Business acumen refers to understanding not only the company’s competitive advantage and financial picture but also the value proposition for your department and yourself. Interprofessional skills, the ability to communicate and work effectively with others, are critical since many industrial projects are multidisciplinary and cross-functional. Recommendations for development in all three areas are described.
Influence of talc and rubber contents on surface replication of polypropylene injection molding application to automotive plastics
Authors: Kuroda Shinichi , Mizutani Atsushi , Ito Hiroshi
Published: December 2018

The influence of talc and rubber contents included in polypropylene (PP) on surface replication properties for microstructure was analyzed. By increasing the talc and rubber contents, surface replication on the injection-molded parts has been reduced. From the surface observation, an uneven microstructure surface was formed for a material containing talc during the shrinkage process. It was confirmed that if the PP resin contains talc, then the correlation between glossiness of the mold and glossiness of the molded product was lost and glossiness was decreased. On the contrary, as the rubber content increased, the replication properties improved. At the same time, generation of the streak pattern in the transferred area, which was generated in the base PP, decreased and glossiness increased. Moreover, the fine uneven structure of the nontransferred area, as observed in the talc-containing material, was not observed in the rubber-containing material.
Routine politeness in American and British English requests: use and non-use of please
Authors: Murphy M. Lynne , Felice Rachele De
Published: December 2018

This paper looks at the use and non-use of please in American and British English requests. The analysis is based on request data from two comparable workplace email corpora, which have been pragmatically annotated to enable retrieval of all request speech acts regardless of formulation. 675 requests are extracted from each of the two corpora; the behaviour of please is analyzed with regard to factors such as imposition level, sentence mood, and modal verb type. Differences in use of please between the two varieties of English can be accounted for by viewing this as a marker of conventional politeness rather than face-threat mitigation in British English and as a marker of relationship asymmetry in American English.

O presente artigo traz um recorte da minha dissertação de mestrado intitulada Educação Ambiental e Ações de Sustentabilidade na Escola, pesquisa que teve como objetivo analisar as experiências no âmbito de uma horta escolar, utilizada como estratégia pedagógica e interdisciplinar para o aprendizado de questões ambientais. A referida pesquisa partiu do pressuposto de que a presença de uma horta escolar pode servir como estratégia para despertar o interesse em alunos e professores sobre questões relativas à educação ambiental (EA), além de possibilitar o desenvolvimento de diversas atividades pedagógicas relacionadas ao assunto. A pesquisa foi realizada na Escola Municipal Vereador Américo dos Santos, localizada na Cidade de Mesquita, na Baixada Fluminense - Rio de Janeiro. Surgiu, em 2015, com o objetivo de auxiliar a formação dos alunos e da comunidade escolar em relação à educação ambiental. O Projeto envolve professores e alunos da primeira e da segunda etapa do Ensino Fundamental. O projeto de construção da horta foi desenvolvido em parceria com professores e alunos do Ensino Fundamental, buscando uma proposta de ação coletiva e organizada, com aportes de diferentes saberes e fazeres, com vistas à conscientização de alunos e de professores para a preservação do meio ambiente e para o desenvolvimento sustentável. A horta escolar se insere, portanto, nesse contexto, como ferramenta para a escola, que está entre os agentes mais importantes no processo de conscientização.

O instrumento EORTC IN-PATSAT32, que afere a satisfação de pacientes hospitalizados com câncer e sua percepção da qualidade dos cuidados hospitalares recebidos, tem demonstrado possuir a robustez necessária para ser utilizado em pesquisas científicas. Desta forma, o objetivo deste estudo é descrever a primeira fase do processo de adaptação trans­cultural da versão brasileira do EORTC IN-PATSAT32. Trata-se de um estudo metodológico baseado no mo­delo universalista que focalizou as quatro primeiras etapas do processo de adaptação trans­cultural: avaliação das equivalências conceitual, de itens, semântica e operacional. Para tanto, foram feitas revisão da li­teratura, discussão com especialistas, tradução e retrotradução dos itens, além de pré-testes. Os Pré-testes re­alizados com 24 pacientes hospitalizados revelaram que alguns itens ainda não captavam os construtos subja­centes pretendidos. Após mudanças em sua re­dação, os itens foram compreendidos corretamente por outros 16 pacientes hospitalizados, conforme proposto pelo instrumento original. Os resultados indicam que a ver­são brasileira do EORTC IN-PATSAT32 pa­rece promissora quando aplicada por entrevistador.

Published: December 2018

O microrrevestimento asfáltico a frio, por tratar-se de uma solução economicamente viável e de fácil aplicação, vem sendo utilizado constantemente em obras de manutenção e conservação de rodovias. Porém, como nem sempre os locais e condições de aplicação são ideais, os métodos de controle e execução do microrrevestimento não são suficientes para obter-se o desempenho ideal da mistura. Neste contexto, o presente estudo apresenta um levantamento sobre as variáveis que influenciam na aplicação do microrrevestimento, identificadas a partir da execução do mesmo em um trecho da rodovia BR-293 e de estudos realizados juntamente com empresas ligadas a este tipo de serviço, visando identificar como essas variáveis interferem no desempenho da mistura e assim, propor melhorias no processo de controle e execução. Pelo fato de existirem muitas variáveis que podem interferir diretamente no desempenho do microrrevestimento, pode-se afirmar tranquilamente que ainda há necessidade de realização de muitas outras pesquisas relacionadas com a utilização dessa solução, para que se tenha maior segurança em relação às potencialidades desse tipo de revestimento e para que se possa realizar o controle de sua execução de forma eficaz e eficiente.

Authors: Muta Luís Filipe
Published: December 2018

A construção civil é um setor de alta relevância para a economia, afetando de forma direta e indireta outros setores. Entretanto, as atividades e processos da construção civil consomem demasiados recursos naturais, acarretando em impactos ambientais, econômicos e sociais. Faz-se necessário o emprego de medidas que reduzam os impactos causados pelo setor, assim, tornando a construção civil um ramo mais sustentável e menos impactante. Nesse âmbito é apresentado o software EDGE, que demonstra de forma simples e rápida o dispêndio energético de uma edificação residencial unifamiliar, objeto de estudo, e propõe medidas para ampliar a eficiência energética. Foram simuladas três propostas para otimizar a eficiência energética da edificação. Após a adoção das estratégias, a melhor proposta apresentou redução de 33,16% no consumo de energia, 77,59% no consumo de água e 75,41% na energia incorporada na edificação.

Germline and mosaic mutations causing pituitary tumours: genetic and molecular aspects
Authors: Pepe Sara , Korbonits Márta , Iacovazzo Donato
Published: December 2018

While 95% of pituitary adenomas arise sporadically without a known inheritable predisposing mutation, in about 5% of the cases they can arise in a familial setting, either isolated (familial isolated pituitary adenoma or FIPA) or as part of a syndrome. FIPA is caused, in 15–30% of all kindreds, by inactivating mutations in theAIPgene, encoding a co-chaperone with a vast array of interacting partners and causing most commonly growth hormone excess. While the mechanisms linking AIP with pituitary tumorigenesis have not been fully understood, they are likely to involve several pathways, including the cAMP-dependent protein kinase A pathway via defective G inhibitory protein signalling or altered interaction with phosphodiesterases. The cAMP pathway is also affected by other conditions predisposing to pituitary tumours, including X-linked acrogigantism caused by duplications of theGPR101gene, encoding an orphan G stimulatory protein-coupled receptor. Activating mosaic mutations in theGNASgene, coding for the Gα stimulatory protein, cause McCune–Albright syndrome, while inactivating mutations in the regulatory type 1α subunit of protein kinase A represent the most frequent genetic cause of Carney complex, a syndromic condition with multi-organ manifestations also involving the pituitary gland. In this review, we discuss the genetic and molecular aspects of isolated and syndromic familial pituitary adenomas due to germline or mosaic mutations, including those secondary toAIPandGPR101mutations, multiple endocrine neoplasia type 1 and 4, Carney complex, McCune–Albright syndrome, DICER1 syndrome and mutations in theSDHxgenes underlying the association of familial paragangliomas and phaeochromocytomas with pituitary adenomas.
Rpd3L Contributes to the DNA Damage Sensitivity ofSaccharomyces cerevisiaeCheckpoint Mutants
Authors: Gómez-González Belén , Patel Harshil , Early Anne , Diffley John F X
Published: December 2018

DNA replication forks that are stalled by DNA damage activate an S-phase checkpoint that prevents irreversible fork arrest and cell death. The increased cell death caused by DNA damage in budding yeast cells lacking the Rad53 checkpoint protein kinase is partially suppressed by deletion of the EXO1 gene. Using a whole-genome sequencing approach, we identified two additional genes, RXT2 and RPH1, whose mutation can also partially suppress this DNA damage sensitivity. We provide evidence that RXT2 and RPH1 act in a common pathway, which is distinct from the EXO1 pathway. Analysis of additional mutants indicates that suppression works through the loss of the Rpd3L histone deacetylase complex. Our results suggest that the loss or absence of histone acetylation, perhaps at stalled forks, may contribute to cell death in the absence of a functional checkpoint.
El conflicto en las emociones recalcitrantes
Authors: Mesa Alvarado Laura
Published: December 2018

En general, todas las emociones comparten ciertas características que les son inherentes: tienen conductas asociadas y tienen objetos intencionales; además, en las emociones recalcitrantes el sujeto hace un juicio sobre el objeto intencional que entra en conflicto con la emoción. Un caso típico es el miedo a volar: una persona se rehúsa a volar en avión, pero juzga que no hay nada que implique peligro en esa acción. Dado que las conductas que involucra la emoción son acciones intencionales del sujeto que tienen un objetivo contrario a su juicio, se propone que dichas emociones son irracionales.
Holismo intencional y el problema de la comunicación
Authors: Rivera-Novoa Ángel
Published: December 2018

El holismo intencional captura rasgos intuitivos de nuestra vida mental, pero no explica cómo es posible la comunicación entre agentes. Aceptar el holismo parcial o molecularismo intencional como solución al problema, invoca la distinción entre juicios analíticos y sintéticos. En este artículo se propone que es consistente sostener el molecularismo, el rechazo a la distinción analítico/sintético y la posibilidad de la comunicación. Se defiende que la argumentación de Brandom para hacer consistentes las tres tesis presenta problemas metodológicos. Además, se proponen dos criterios que identifican la capacidad de una creencia para individuar el contenido de otras creencias, sin apelar a la distinción analítico/sintético.
Experiencia perceptual, vaguedad y realismo ingenuo
Authors: Amado Manuel Alejandro
Published: December 2018

Filósofos modernos como Berkeley y Hume desplegaron una argumentación de corte escéptico en contra del llamado realismo ingenuo: la idea de que la experiencia perceptual provee un accesodirecto al mundo. Dicha argumentación ha sido criticada por Michael Martin y John Campbell, quienes reclaman justicia por una nueva forma de realismo ingenuo llamado relacionalista. Se argumenta que tanto el realismo ingenuo como el relacionalista son falsos, y se defiende la tesis central de Berkeley y Hume: no hay experiencias perfectamente verídicas de objetos materiales.
Causal versus constitutivo. ¿Dónde debemos trazar los límites de la mente?
Authors: Toro Juan
Published: December 2018

¿Cómo saber qué entidades causan los procesos mentales y qué entidades los constituyen? La relevancia de esta pregunta cobra fuerza a partir de la objeción de Adams y Aizawa a la teoría de la mente extendida. Este artículo reconstruye algunos argumentos a favor la teoría de la mente extendida y del externalismo de la conciencia. Posteriormente, se evalúa la propuesta de Kirchhoff de una noción de constitución como una relación entre niveles. Actualmente la discusión carece de un acuerdo básico sobre los términos de la disputa, lo que hace indecidible el problema y debilita por igual la posición de ambas partes.
Valores hematológicos del mono choro común (Lagothrix lagotricha) mantenido en cautiverio en la ciudad de Lima (Perú)
Authors: Cuestas K. , Carlos N.
Published: December 2018

La disminución de las poblaciones del mono choro común (Lagothrix lagotricha) ha conllevado a categorizarlo como especie amenazada, además, muchos ejemplares se mantienen en cautiverio debido al tráfico ilegal. La hematología es una herramienta muy útil para evaluar el bienestar y diagnóstico de condiciones patológicas, siendo necesario contar con parámetros referenciales para todas las especies de primates mantenidas en cautiverio. El objetivo del presente estudio fue determinar los valores hematológicos de ejemplares de mono choro común (L. lagotricha) bajo cautiverio en los zoológicos de la ciudad de Lima, (Perú). Para ello, el estudio contó con una población total de 28 individuos distribuidos en siete zoológicos, 16 hembras y 12 machos de cuatro grupos etarios diferentes. Se realizó la captura y contención físico-química de los primates utilizando mallas y un protocolo anestésico combinando clorhidrato de ketamina y xilazina. Las muestras de sangre se obtuvieron por punción de la vena femoral, se colectaron en tubos estériles con anticoagulante EDTA y se mantuvieron en refrigeración hasta su análisis. Se obtuvieron los siguientes resultados: eritrocitos 8,76 x 106/μl (± 2,91); hematocrito 36,46% (± 3,38); hemoglobina 12,32 g/dl (± 1,89); VCM 60,61 fl (± 7,85); HCM 20,37 pg (± 3.07); CMCH 33,85 g/dl (± 4,61); leucocitos 6,12 x 103/µl (± 1,05); abastonados 0,05 x 103/µl (± 0,11); segmentados 5,54 x 103/µl (± 2,23); linfocitos 2,62 x 103/µl (± 1,60); monocitos 0,07 x 103/µl (± 0,02); eosinófilos 0,42 x 103/µl (± 0,23); basófilos 0,13 x 103/µl (± 0,14) y plaquetas 314,39 x 103/µl (± 78,09).

Published: December 2018

En los últimos años, el agronegocio porcino creció significativamente a nivel nacional y departamental. Esta cadena productiva está conformada por proveedores de insumos, productores primarios, comercializadores, agroindustria, comercio mayorista, comercio minorista y consumidores. Este estudio caracterizó los agentes del mercado que interactúan a lo largo de la cadena productiva, y además cuantificó los márgenes de comercialización de la carne de cerdo en la subregión del Valle de Aburrá, departamento de Antioquia. Se aplicó muestreo no probabilístico a conveniencia. Adicionalmente, se aplicó una encuesta a 30 productores y entrevista semiestructurada a cinco agentes de mercadeo. Se encontraron dos circuitos de comercialización principales: productor–expendedor de carne y productor–intermediario–expendedor de carne. Los precios pagados a los agentes que interactúan en el circuito de la carne de cerdo en el Valle de Aburrá presentan tendencia al alza. El precio pagado por el consumidor final al expendedor de carne crece en mayor proporción que los precios pagados a la intermediación y al productor primario.
Efecto del nivel de complementación con Metionina-Colina en vacas Holstein durante el periodo de transición sobre las concentraciones hepáticas de triglicéridos, colina y carnitina
Authors: Galvis R. D. , Montoya J. A. , Madrid L. V.
Published: December 2018

Con el objetivo de evaluar el potencial lipotrópico de metionina-colina en vacas lecheras durante el periodo de transición, dosis de 20 g/d de una Fuente Comercial Protegida de la Degradación Ruminal (FCPDR) de metionina, y sus combinaciones con una FCPDR de colina en dosis de 60 y 120 g/d fueron suministradas a vacas entre el día 260 de gestación y el día 20 posparto. Estas     pastoreaban kikuyo (Cenchrus clamdestinum) y recibieron un complemento alimenticio.  El día 270 de gestación y a los días 10 y 20 posparto se cuantificaron las concentraciones plasmáticas de Ácidos Grasos No Esterificados (AGNES), β-Hidroxibutirato (BHB) y Triglicéridos (TG), así como las concentraciones hepáticas de triacilglicéridos, de colina, carnitina total, carnitina libre y acil carnitina. Durante el preparto se presentaron los valores significativamente más altos (p < 0.05) de TG plasmáticos y los valores significativamente más bajos (p < 0.05) de AGNES y BHB.  Las concentraciones hepáticas de TG, de colina y de las diferentes formas de carnitina no difirieron significativamente entre periodos de muestreo y no se vieron afectadas por la suplementación con metionina-colina.  Las concentraciones plasmáticas de BHB aumentaron significativamente (p < 0.05) con la suplementación conjunta con metionina y colina, sugiriendo un aumento en la oxidación de ácidos grasos.  Se concluye que con concentraciones bajas de AGNES, la metionina y colina no son nutrientes limitantes para la exportación de TG desde el hígado a la sangre. Bajo esta condición no se observó lipidosis hepática y como consecuencia la suplementación con metionina-colina no ocasionó efectos significativos sobre las concentraciones hepáticas de TG.

Published: December 2018

Objectives

Fatigue is a limiting factor for sport performance. For this reason, optimal recovery after training is just as critical as the training program itself, if not more. Indeed, there is a need for strategies that can facilitate recovery after training, and one such strategy is the ingestion of supplements like melatonin (MEL). This study aimed to evaluate if MEL intake could improve recovery of athletes after an intermittent training session (ITS).

Methods

Fifteen elite female athletes (17.4 ± 0.4 years, 76.4 ± 5.6 kg, 1.76 ± 0.04 m; mean ± standard deviation) participated in two testing campaigns. During each period, they performed a battery of physical and cognitive tests before and after an ITS, as well as after ingesting MEL (6 mg tablet) or placebo in a randomized design. The ITS comprised the modified agility T-test, squat jump, counter movement jump, maximum standing ball-throw velocity test, maximum jump ball-throw velocity test, and 20-m sprint. Oral temperature (OT) and vigilance were evaluated before and after the ITS. Rating of perceived exertion (RPE), blood lactate [La], and glucose [Gl] were recorded after each ITS.

Results

Short-term performance, recovery of physical performance, and OT were not affected by MEL ingestion after the ITS. Moreover, MEL did not affect cognitive performance or RPE scores after the ITS. However, [La] and [Gl] (p < 0.05 for both) were decreased after MEL ingestion.

Conclusion

MEL has no effect on the recovery of physical performance but may affect glucose utilization and lactate metabolism during the team-handball training session.
Crack propagation in porous polymer sheets with different pore sizes
Authors: Takei Atsushi , Okumura Ko
Published: December 2018

Physical understanding of crack propagation is a fundamental issue in the industry. In the literature, crack velocities of polymer materials are strongly dependent on their visco-elastic properties and energy release rates. Recently, numerical and theoretical studies have proposed that structural sizes in polymers also influence on crack propagation. Here, using polymer sheets with similar visco-elastic properties but with different pore sizes, we vary explicitly the representative structural size and examine the effect of the size on crack propagation. Findings in this work help us to understand crack propagation in polymer materials and bio-inspired materials which have porous structures.
Effect of different nanoscale microelements containing formulations for seed treatment on germination and growth of maize seedlings
Authors: Hiền Đào Trọng
Published: December 2018

Effect of the nutrient formulations for pre-sowing seed treatment on germination and growth of maize seedlings was studied. The formulations comprised separate copper nanoparticles (NanoCu), IET1- based on a Novalon Seed Treatment product, IET2 - based on humate metal-organic-coordination complexes (MOC), Nualgi – based on nano silica, wherein microelements were adsorbed on the surface of the silica nanoparticles, and formulations with microelements in a form of Metal-EDTA complexes, based on commercial fertilizer products of Novalon, Wuxal and Comex companies. Results of the study showed that all the tested formulations, except for the separate nanocopper formulation, demonstrated visibly higher stimulation effects on the maize seedlings growth, among which the nanoscale microelements-containing seeds treatment formulations produced in Institute of Environmental Technology (IET1 and IET2) exhibited the best growth indices although non-significantly differed as compared with the control. The experimental data presented also proved that for obtaining stable stimulation effects on the plant growth kinetics instead of using separate nanosized microelement it is preferable to use complex formulations, wherein besides of microelements there are other components included such as plant regulators, amino- and carboxylic acids, plant protection agents etc.

The Magnetostratigraphy and the Age of So’a Basin Fossil-Bearing Sequence, Flores, Indonesia
Authors: Yurnaldi Dida , Setiawan Ruly , Patriani Emma Yan
Published: December 2018

DOI: 10.17014/ijog.5.3.221-234Three fossil-bearing intervals have been recognized in the Pleistocene So’a Basin, with the upper one holding important evidence of hominin fossils. The sequence also contains numerous in situ stone artifacts and fossils of other vertebrate taxa. Therefore, multiple dating techniques are crucial to secure the age of the fossil and artifact-bearing layers, especially the one with the hominin remains. This paper deals with the palaeomagnetic dating of the So’a Basin sequence to assist other dating methods that have been applied, and to refine the chronostratigraphy of the area. Palaeomagnetic sampling was conducted in four sections along a west to east transect. Four magnetozones can be recognized, consisting of two reverse and two normal polarity zones. By using the available radiometric ages as a guide and comparing the So’a Basin magnetostratigraphy with the Standard Geomagnetic Polarity Time Scale (GPTS), it became clear that both reverse magnetozones are part of the Matuyama Chron, while the normal magnetozones are the Jaramillo subchron and the Brunhes Chron. These palaeomagnetic dating results support the available radiometric dates and refine the age of the fossil-bearing deposits of the So’a Basin.
Tectonic Control on the Formation of Cleats in the Coal Beds of the Sajau Formation, Berau Basin, Northeast Kalimantan
Authors: Sudradjat Adjat , Hamdani Ahmad Helman
Published: December 2018

DOI: 10.17014/ijog.5.3.235-250Coal seams of lignite- to subbituminous rank of Pliocene-age from the Sajau Formation of the Berau Basin are characterized by the presence of a natural fracture system, including cleats. Often, these opening-mode fractures consist of two orthogonal sets (face and butt cleats), both almost perpendicular to the bedding. This paper describes the distribution of orientation, spacing, and aperture of cleats formed in the seams of the Sajau Formation. All observations and measurements were conducted at macroscopic, mesoscopic, and microscopic scales. The butt cleat mean orientations are NE-SW and NW-SE, whereas the face cleat mean orientations are NNE-SSW and NE-SE, and the cleat dip is at a high angle of 75° to the north. The angles between the orientations of these cleat sets are nearly 90°; that is, they are orthogonal. The spacing of the macroface cleats is between 9.52 and 14.46 cm (averaging 11.61 cm), while the spacing of the butt cleats is between 2.3 and 11.3 cm (averaging 5.35 cm). The mean aperture is 0.54 mm. In contrast, the mean spacing of the mesoface cleats is 3.09 mm, and the aperture measurements of these cleats range from 0.0478 to 0.0741 mm (averaging 0.0549 mm). The results obtained from outcrops and X-ray CT (computed tomography) scan clearly indicate that the NNE-SSW face cleat orientations are strictly parallel to the elongation of the main tectonic structures in the studied area. Their origin may be explained by their relationship with local tectonic stress (the maximum principal stress, σ1, was horizontal). Partial least square analysis of data collected from cleats and faults in the area indicates that a power law distribution exists between the cleat characteristics (spacing, density, and aperture), and the distance of the faults (R2 = 0.56). Cleat formation in the Sajau Formation was mainly controlled by the mechanical response to tectonic stresses, which generated a unique cleat network in the coal. Based on the SEM photography, it is concluded that the development of microcleats in the Sajau Formation resulted from both endogenic processes and tectonic activities as indicated by the change in the shape of the cleats, from straight line to curved shape and branching (intersection of multiple cleats that form a conical network at the end).

Published: December 2018

Objetivo: Analizar las dimensiones culturales del empleo y desempleo de jóvenes universitarios de Cali, Colombia.

Método: Estudio de antropología cognitiva. Se utilizaron listados libres y pile sort para identificar el contenido y la organización de las dimensiones. Participaron 80 jóvenes (40 hombres y 40 mujeres, con edad promedio de 20.5 años), seleccionados por muestreo propositivo.

Resultados: El empleo es una actividad laboral que genera satisfacción, permite contar con seguridad económica y acceso a beneficios materiales. Requiere de competencias, valores de tipo personal y contar con la oportunidad para acceder a ello. Implica esfuerzo a fin de tener crecimiento, superación, estabilidad, progreso y futuro. Puede generar frustración por falta o dificultad para alcanzar logros en el ámbito laboral así como la percepción de esclavitud por exceso de trabajo. Se le visualiza como una actividad que se desempeña en empresas o instituciones y en contacto con compañeros. El desempleo es un tiempo perdido que genera pobreza y necesidades, es producto de problemas sociales como la desigualdad, falta de oportunidades, así como por causa del sistema social. Produce situaciones delictivas e impactos comunitarios; en lo personal genera problemas, necesidades, complicaciones y la vivencia de emociones negativas. Es un desafío que lleva a destacar las responsabilidades que se tiene hacia la familia, mas no se especifica alguna alternativa de afrontamiento al mismo.

Conclusiones: los jóvenes participantes mostraron alto consenso en la forma de conceptualizar al empleo y al desempleo. Ello indica competencia cultural sobre los dominios culturales de los conceptos estudiados.

Published: December 2018

Se evaluó la variación fenotípica a través de 28 variables anatómicas y morfológicas mediante análisis discriminantes en poblaciones de Opuntia cantabrigiensis, O. leucotricha, O. rastrera, O. robusta y O. streptacantha que se encuentran separadas entre sí por distancias de entre 32 y 11O km. La altitud y la temperatura media anual no mostraron variación en el área de estudio. El análisis separa las poblaciones de O. cantabrigiensis , que es la especie con menor densidad (13 individuos ha-1),  mientras que para el resto de las especies, cuyas poblaciones pueden alcanzar hasta 1,852 individuos ha', algunas poblaciones se yuxtaponen. No hay diferencias en los niveles de ploidía entre las poblaciones, a pesar de que se registraron niveles de ploidía entre diploide ( O. cantabrigiensis ) a octoploide ( O. streptacantha ). Por lo tanto, las diferencias fenotípicas entre las poblaciones parecen estar relacionadas con la densidad de individuos y no con variables ambientales, dada Ja falta de gradientes ambientales o a cambios en el nivel de ploidía de las distintas especies.
Suspender el mundo. Crisis de la presencia y reciprocidad en un caso etnográfico
Authors: Martínez Hernáez Ángel
Published: December 2018

El concepto de «crisis de presencia» (crisi della presenza) fue acuñado por Ernesto de Martino en sus ensayos teóricos y desarrollado en sus estudios etnográficos sobre magia y ritual en el sur de Italia. Esta noción aborda la fragilidad de la presencia (esserci) en un mundo que amenaza con colapsarla, y que se expresa en la pérdida de la distinción entre sujeto y objeto, entre pensamiento y acción, entre representación y juicio. Para De Martino, una de sus expresiones radicales es el latah, un síndrome de filiación cultural del sudeste asiático y estado disociativo en el que el sujeto se convierte en vulnerable a las influencias externas hasta el punto de que se difumina la distinción entre presencia y mundo. Tomando como base algunos datos de mi trabajo etnográfico entre los madiha de Amazonas (Brasil), en este artículo propongo una redefinición de la teoría demartiniana donde la presencia y su crisis se abordan a través de una refiguración ontológica de la dualidad sujeto/objeto.
Revelar la violència, denunciar el mal
Authors: Fernández Miquel
Published: December 2018

Propulsats pels lemes de civisme i espai públic, les nostres institucions estan normalitzant la intolerància envers el desordre urbà, la brutícia, els fenòmens impredictibles o els segments poblacionals més vulnerables. Paradoxalment, aquesta mena de fonamentalisme de «l’ordre públic» pot estar convertint els barris més cobejats pel capital global immobiliari en llocs inhabitables i caracteritzats per una intolerància creixent. A partir d’una recerca historicoantropològica sobre el barri del Raval de Barcelona, aquest article il·lustra les contradiccions inherents i arquetípiques dels projectes anomenats de «revitalització» o «regeneració urbanística» i discuteix les seves implicacions morals, així com les que són consubstancials a l’ofici d’investigador social.

Medicina popular, medicinas alternativas y new age: hacia un «nuevo mundo mágico»
Authors: Riccò Isabella
Published: December 2018

En consecuencia de la desaparición progresiva del «modelo clásico de medicina popular» (a partir de los primeros años noventa), los estudios sobre los rituales terapéuticos tradicionales en España e Italia se han reducido drásticamente. No obstante, mediante este artículo se evidencia que muchas de estas terapias y creencias han sido recuperadas y readaptadas mediante las medicinas alternativas y complementarias (MAC) y las terapias New Age (NA). Asimismo, se destaca también la difusión del modelo holístico en relación a situaciones de sufrimiento social generadas por la «nueva crisis de la presencia» y la hegemonía de la cultura capitalista. Los tratamientos alternativos se presentan como una forma de resistencia al sistema y una herramienta de reimplantación de un (nuevo) mundo mágico. Sin embargo, el peligro de este nuevo mundo mágico emerge cuando el espíritu crítico está ausente y se incorpora un modelo en su totalidad sin cuestionarse sobre sus límites y contradicciones.
Protocol for Pilot Trial of a Longitudinal fMRI study in 5 Patients Treated with Pulsed Radiofrequency on the Dorsal Root Ganglion to Analyze Changes in Functional Connectivity of the Dynamic Pain Connectome in Neuropathic Pain v1
Authors: Bourgonjon Bram , De Coster Olivier , Forget Patrice , Poelaert Jan
Published: December 2018

Background Pulsed radiofrequency on the dorsal root ganglion is a technique frequently used in pain centres throughout the world for the management of lumbo-radicular neuropathic pain. Evidence regarding the clinical outcome of this intervention is still limited, although a fundamental pathophysiologic working mechanism at the spinal level has been published. Methods We propose a new hypothesis to explain the central effects of this technique: the modification of the pain signal at the spinal level should ultimately have its effect on the dynamic pain connectome. We are currently conducting a pilot trial to demonstrate these changes on fMRI imaging, where we compare the difference in activity of resting state fMRI before and after pulsed radiofrequency on the dorsal root ganglion Discussion This hypothesis and feasibility study should provide fertile ground for further investigations and clinical studies on this topic.
Assessing the Vibration Fatigue Life of Engine Mounted Components
Authors: Bonato Marco , Goge Philippe
Published: December 2018

As part of the design validation of components mounted on rotating machinery such as a car engine, it is essential to understand the environmental stress in which they operate. In the case of vibration loadings, the reliability must be verified according to accelerated tests that realistically reproduce the in-service stress. Indeed, a representative validation profile permits not only the assessment of the component durability, but also provides a reliable reference for design optimization (downsizing), reducing development cycle costs, and time scale. This paper proposes an innovative methodology to generate tailored vibration signals more representative of the real environment. First, the severity of the test is tailored to the specific engine usage profile, i.e., the time spent at each revolution per minute (RPM) for a given percentile of customer usage. Traditional signals of Power Spectrum Density (PSD) and sine sweep are developed according a fatigue damage approach (test tailoring). Then, a more representative vibration specification is obtained as a multiple-sine-on-random signal. The signal is expressed as a series of multiple sine sweeps (representing the engine harmonics) and a PSD (representing the random leftover signal). A case study applied to an engine mounted heat exchanger (a water-cooled intercooler) is presented. The generated specification is compared to the validation signals developed according to existing procedures. The results show that 1) the tailored approach decreases the risk of unnecessary over-testing and 2) the multi-swept-sine-on-random signal guarantees the best representativeness of the real environment.

AN ATTEMPT FOR THE PROTECTION OF SEXUAL DIVERSITY IN BRAZILIAN LAW
Authors: Pereira Marcos Vinicius Torres
Published: December 2018

This article intends to talk about a democratic initiative of the Brazilian Bar Association to promote human rights and sexual diversity in Brazil.  Brazil is walking up the road to protect LGBTI citizens and to legally recognize same-sex couples.  The country has guaranteed many rights to homosexual couples and their children, but the lack of a specific act to rule these matters is a problem in a country whose legal system is still very dependent to legal acts and positivism.  This work tries to show the state of art of homosexual couples’ rights in Brazil and how the proposal of a new statute to protect the rights of LGBTI people, in all aspects of their daily life could protect them and contribute for a democratic society.
THE MARRAKESH TREATY RATIFICATION IN BRAZIL: IMMEDIATE EFFECTS
Authors: Souza Allan Rocha de , Fairbanks Alexandre De Serpa Pinto
Published: December 2018

This paper willpresent the ratification process of the Marrakesh Treaty in Brazil, its place within the legal system and the likely effects on copyright limitations. We structure the paper in two parts. First we show how the Brazilian Constitution governs the reception of human rights international treaties and conventions and expose their effects throughout the system. We follow by the presentation of the Marrakesh Treaty’s ratification process in Brazil, concentrating on the justifications and results of the legislative procedures. Finally, we consider the likely and possible effects on public policy, legal change and the judicial interpretation of the limitations. We choose to use primary official sources to present the questions for analyses. Our method of choice is inductive, since we extensively use legislative records to elaborate on the political processes and legal rationales behind it.
DEMOCRACY AND JUSTICIABILITY OF THE RIGHT TO EDUCATION – THE BRAZILIAN EXPERIENCE
Authors: Ranieri Nina Beatriz
Published: December 2018

Democratic regimes establish themselves to the extent to which they are accepted by the majority of the population living under them. This acceptance is translated into a knowledge of and trust in their respective political and legal institutions. Quality education is relevant to democratic governance and citizenship building, as it provides access to the cognitive tools needed for significant political participation. This paper analyzes the interactions between democracy and quality education in the light of judicial proceedings being applied to the right to education, focusing on Brazilian Supreme Court (STF) activities in the period between 2000 and 2010.
Estudio exploratorio sobre lenguajes simbólicos de programación en tareas de resolución de problemas con Bee-bot/ Exploratory study on symbolic programming languages in problem-solving activities with Bee-bot
Authors: Pérez Buj Gema , Diago Nebot Pascual D.
Published: December 2018

En los últimos años movimientos relacionados con la robótica educativa, el movimiento maker o el movimiento STEM han potenciado la integración en las aulas de contenidos de matemáticas con otros propios de las ciencias de la computación. El uso de entornos tecnológicos en educación, así como el resurgimiento de la programación en la escuela son tendencia consolidada en el panorama educativo. En este estudio pretendemos explorar la capacidad de estudiantes de infantil y primaria para elaborar esbozos de programas a partir de su lenguaje propio así como explorar la conveniencia del uso de un lenguaje de programación simbólico para resolver un problema. Así, desde la perspectiva de la resolución de problemas de matemáticas, observaremos actuaciones en las que el estudiante debe idear, generar, desplegar y gestionar estrategias que le permitan abordar el problema (con o sin éxito) con la restricción de que la solución obtenida debe poder implementarse en un entorno tecnológico.
¿Qué explica la violencia letal en Paraguay? Un estudio con intención comparativa
Authors: Solís Delgadillo Juan Mario , Cerna Villagra Sarah Patricia , Peris Castiglioni Carlos Aníbal
Published: December 2018

En la lógica de los rankings, Paraguay es un país pacífico donde el crimen no representa un problema grave como sucede en otras naciones latinoamericanas; sin embargo, en algunos de sus departamentos las tasas de violencia solo se comparan con las de los territorios más violentos de la región. Este artículo busca identificar las condiciones de suficiencia que permitan explicar por qué ciertos departamentos paraguayos son notablemente más violentos que otros. Para ello se comparan nueve de ellos, dividiéndolos entre los más y los menos violentos. Los principales hallazgos muestran que aquellos con una orografía más accidentada y en los que se dificulta la cobertura efectiva por parte del Estado, son los que concentran las mayores tasas de homicidios, y que, en contraste con lo que ocurre en países como México, la coordinación política entre el gobierno nacional y los subnacionales tiene una correlación inversa a lo planteado en la teoría.
