Thermal Instability of Self-Gravitating Partially-Ionized Gaseous Plasma
Authors: Pensia Ram K. , Shrivastava V. , Kumar Vishal , Patidar Ashok K. , Prajapat Vikas
Published: May 2018

The effect of radiative heat-loss function on the Jeans instability of an infinitely conducting, homogeneous partially ionized gaseous plasma is investigated. It is assumed that the medium is carrying a uniform magnetic field in the presence of porosity and thermal conductivity. With the help of relevant linearized perturbation equations of the problem, a general dispersion relation is obtained for a such medium using the normal analysis technique, which is reduced for both the transverse and the longitudinal mode of propagation. The longitudinal mode is found to be modified by Alfven speed and parameter of porosity. The thermal mode is obtained separately having the effects of thermal conductivity and arbitrary radiative heat-loss functions. The effect of collision with neutrals and magnetic field have a stabilizing effect, while thermal conductivity has destabilizing influence on the Jeans instability of gaseous plasma. In the transverse mode of propagation, we find the condition of radioactive instability depends on thermal conductivity, magnetic field and the porosity of the medium.

A spin to spark creativity: The role of early Jamaican popular music recordings in Los Angeles’ traditional ska scene
Authors: Cole Nina
Published: May 2018

In the late 1980s, a revival movement dedicated to 1960s Jamaican popular music began taking shape in Los Angeles, CA. Hepcat and Jump With Joey were two bands at the forefront of this movement, playing their own interpretations of Jamaican ska, rocksteady and reggae, interlaced with genealogically related influences. Using oral history interviews I conducted with band members, I analyse the role of recorded media in shaping Angeleno adaptations of 1960s Jamaican popular music. In doing so, I highlight how audio recordings help stimulate cross-cultural and inter-generational communication and explore the complexities of music revival subcultures and generic classifications.

Authors: López-Negrete Miranda Christian Eugenio
Published: May 2018

This article discusses various issues surrounding the presence of Jamaican popular music in Mexico and focuses on issues of great importance as the arrival, development, adoption and adaptation of these musical practices that arise in specific times or time periods; in different levels of locality that are related to each other, at the same time related to the global; and that they express themselves by reinterpreting these genres in their own ways. Each period has characteristics that distinguish it and at the same time coexist today in a same musical scene that involves several smaller scenes, as much regional as stylistic, in which continue to arise new expressions of reggae in Mexico.
A liberdade de consciência do jornalista precisa de proteção especifica a bem da independência no seu trabalho, do pluralismo e da democracia?
Authors: Leitão Otília
Published: May 2018

Poucos conhecem a real profundidade da garantia de independência e da cláusula de consciência (artigo 12.º do Estatuto do jornalista). São raros os que as invocam e outros, perante a precariedade laboral, preferem, tornear os atropelos de quem os tenta submeter. Nesta nova era de apropriação cidadã das novas tecnologias que potenciam a liberdade de expressão e exigem maior credibilidade ao modus de fazer jornalismo, começa a desenhar-se a necessidade de novas práticas, direitos e deveres num desempenho mais interativo, enquadrado numa ética cada vez mais global. Nesse sentido é importante refletir a pertinência da reavaliação da “cláusula de consciência” enquanto direito do jornalismo e da sã democracia, princípio irredutível da dignidade e que assume para os jornalistas uma acentuada especificidade pela “imaterialidade “ do seu trabalho, ou, ainda da criação de um mecanismo complementar que garanta a independência do trabalho jornalístico de acordo com as regras éticas e deontológicas reconhecidas e que responsabilize o jornalista, mas também os media para quem trabalham.

Authors: Suryana Joko
Published: May 2018

This paper presents a new approach in designing an ultra wideband minimum dispersion antenna optimally to avoid the degradation of broadband communications system performance. Design and iterative optimization are applied to an arbitrary shape of planar monopole antenna using a genetic algorithm combined with the moment method, abbreviated as AGMM method, and implemented with Matlab. Two arbitrary shapes of planar monopole antennas have been implemented in compact physical size using AGMM optimization, each having 9.1 GHz and 7.4 GHz bandwidths, the lowest frequency of 1.9 GHz and 2.7 GHz and fidelity 0.6 and 0.64 for any arbitrary discrete antenna and edge profile antenna. This method can be applied to design any arbitrary shapes of an ultra-wideband antenna with each has wide bandwidth more than 7 GHz, the lowest frequency below 3 GHz and a minimum fidelity of 0,55 that is suitable for high- speed communication, such as 5G system.

Multi-color imaging of sub-mitochondrial structures in living cells using structured illumination microscopy
Authors: Opstad Ida S. , Wolfson Deanna L. , Øie Cristina I. , Ahluwalia Balpreet S.
Published: May 2018

The dimensions of mitochondria are close to the diffraction limit of conventional light microscopy techniques, making the complex internal structures of mitochondria unresolvable. In recent years, new fluorescence-based optical imaging techniques have emerged, which allow for optical imaging below the conventional limit, enabling super-resolution (SR). Possibly the most promising SR and diffraction-limited microscopy techniques for live-cell imaging are structured illumination microscopy (SIM) and deconvolution microscopy (DV), respectively. Both SIM and DV are widefield techniques and therefore provide fast-imaging speed as compared to scanning based microscopy techniques. We have exploited the capabilities of three-dimensional (3D) SIM and 3D DV to investigate different sub-mitochondrial structures in living cells: the outer membrane, the intermembrane space, and the matrix. Using different mitochondrial probes, each of these sub-structures was first investigated individually and then in combination. We describe the challenges associated with simultaneous labeling and SR imaging and the optimized labeling protocol and imaging conditions to obtain simultaneous three-color SR imaging of multiple mitochondrial regions in living cells. To investigate both mitochondrial dynamics and structural details in the same cell, the combined usage of DV for long-term time-lapse imaging and 3D SIM for detailed, selected time point analysis was a useful strategy.
Molding light with metasurfaces: from far-field to near-field interactions
Authors: Hassani Gangaraj Seyyed Ali , Monticone Francesco
Published: May 2018

The field of metasurfaces is revolutionizing the way we control and manipulate light and electromagnetic fields based on engineered ultrathin structures. In this review article, we discuss the theory, modeling, and applications of metasurfaces, with particular focus on controlling the near-field response of sources close to the artificial surface. Although metasurfaces have attracted large attention for their ability to control and mold the wavefront of propagating waves, hence acting as flat lenses, they can also be used to modify the emission/radiation from near-field sources and control the generation and propagation of surface waves guided and confined along the surface. We discuss the analytical modeling of metasurfaces treated as homogenized impedance sheets and elucidate the application and limits of this approach for near-field sources. We devote a large part of the review article to anisotropic and hyperbolic metasurfaces, which enable some of the most exciting and extreme examples of anomalous surface-wave propagation on planarized artificial structures, with important implications for light focusing, confinement, and subwavelength imaging. We also connect these ideas with the emerging area of 2D materials and discuss how to implement hyperbolic metasurfaces with graphene and black phosphorus. We hope that this review article may provide the reader with relevant physical insights and useful analytical tools to study metasurfaces and their near-field interactions with localized sources and, more generally, offer an overview of this field and its ambitious goal of ideal light control on a surface.
From photoinduced electron transfer to 3D metal microstructures via direct laser writing
Authors: Waller Erik Hagen , von Freymann Georg
Published: May 2018

We review the fundamental concepts of direct laser writing (DLW) of 3D metallic structures via photoreduction and give an overview over the state-of-the-art. On the one hand, metallic microstructures and nanostructures play an important role in photonic applications such as resonators, antennas, metamaterials, and polarizers. On the other hand, DLW offers a flexible and fast way to fabricate microstructures. Because the underlying mechanisms from the first photoreaction to the final 3D microstructure are quite complex and not yet well controlled, we believe that a review of the photochemistry and photophysics of the direct writing process of metal structures helps to promote development in this field. To this end, we first summarize the principles of electroplating and electroless plating as this helps understand the photoresist’s components. Next, we describe the different photoreducing agents and photoreactions that lead to metal seeds and in consequence to nanoparticles. This is followed by insights into the physics of nanoparticle agglomeration to the desired microstructure. Finally, we give an overview over the state-of-the-art of DLW metallic 3D microstructures.

Published: May 2018

INTRODUCTION: The aim of this study was to present our current practice of counseling patients and families with the most severe congenital malformations in the 3rd trimester of pregnancy and to develop practical guidelines for our team and involved healthcare/ socialcare professionals. MATERIAL & METHODS: It was a retrospective evaluation of a series of fetal cases in 2017 from single tertiary center. Maternal obstetrical medical history, time of prenatal detection of the anomaly (1st, 2nd or 3rd trimester), time between last fetal echocardiography and delivery, type of delivery, neonatal birth weight and time of neonatal demise. The total study group was subdived into early demise (during the 1st day after delivery) or late demise > 1st day after delivery. RESULTS: Mean maternal age was 30,4 +/- 5,6 years, and varied between 26 and 38 years. No chronic maternal diseases were found in medical history and no congenital malformations were present in previous children. All women had 1st trimester ultrasound, in 9 cases, it was reported as normal (with NT measurement < 2 mm), in 2 cases extracardiac abnormalities were detected: diaphragmatic hernia and omphalocele ( in both fetal karyotype 46,XY). In nine cases, the abnormalities were detected in midgestation and with maternal wish to continue the pregnancies. There were 8 neonatal deaths within 60 minutes after delivery, including one intrapartum death and 3 “late” neonatal deaths in the intensive care unit (on 12th, 21st and 22nd day). We stress upon the prenatal team approach and counseling of future parents, in order to prepare them for poor neonatal outcome. CONCLUSIONS: 1. In the most severe cases when fetal or neonatal demise was suspected, the two different opinions of specialists might not be enough and a third opinion should be recommended before final decision. 2. A Fetal Team of specialists is necessary in cases of expected fetal/neonatal demise in order to prepare a written report of recommended perinatal management for all sides involved in this difficult problem.

Published: May 2018

RESUMO O objetivo deste artigo é avaliar a composição, abundância e riqueza das diatomáceas presentes na zona intermaré da Praia de Itupanema e relacionar esses atributos à hidrodinâmica atual, evidenciada pela textura do sedimento. Foram coletadas 10 amostras em duas transecções perpendiculares, em intervalos de 5 m nas coordenadas 01º31'03"S e 48º43'28"W em março de 2006, sendo analisadas segundo as técnicas convencionais no estudo de diatomáceas. Os resultados mostraram a ocorrência de 58 espécies, 82,75% bentônicas/epifíticas e 17,25% planctônicas, comuns em águas doces a oligo-mesohalinas, as mais abundantes e freqüentes em ordem decrescente foram Staurosirella pinnata, Aulacoseira granulata, Thalassiosira sp., Staurosira obtusa, Encyonema silesiacum, Gomphonema parvulum, Planothidium lanceolatum, Thalassiosira eccentrica, Cyclotella meneghiniana, Encyonema minutum, Nitzschia amphibia e Frustulia sp. Os dados também revelaram a influência da relação areia/argila sobre a composição e a abundância das diatomáceas, o que pode explicar a prevalência local de agrupamentos de espécies ora planctônicas, ora bentônicas na zona intermaré, como resposta aos processos hidrodinâmicos atuais. Há de se salientar a provável contribuição da vegetação herbácea, atenuando a energia das ondas e marés, retendo os sedimentos finos argilosos, promovendo assim, a redução de processos de abrasão na zona intermaré e a conseqüente preservação dos táxons planctônicos.

Objectives: The aim of this study was to analyze high risk breast cancer patients with
involvement of five or more axillary lymph nodes with an overall survival of at
least five years, and to determine the predictive and prognostic factors by
comparing patients by recurrence/metastases status retrospectively. Methods: From a total of 500 patients those were followed up in Adnan Menderes University,
Medical Oncology department, 37 were eligible for the study; 23 were disease
free and 14 had recurrence/metastases in the follow up period. The patients
were analyzed, for demographical (such as age, menopausal status, obesity),
anatomical and histological characteristics of tumor (primary tumor’s diameter,
stage, grade, Ki-67, hormon receptors and Her-2 status), treatment modalities
and prognosis. Results: Both number of metastatic lymph nodes and
(metastatic/sampled) lymph node ratio were not significantly different between
the recurrence-free and metastatic patients. In the recurrence-free patients
both grade 3 (48% vs none, p = 0.03)
and p53 negative tumors (64% vs 36%, p
= 0.036) were significantly more than metastatic patients. Also in the recurrence
free patients as compared to metastatic patients, adjuvant chemotherapy was applied
more than 6 cycles (87% vs 43%, p = 0.004),
the regimens included more taxane based regimens (91% vs 64%, p = 0.042), aromatase inhibitors were
used higher (100% vs 75%, p = 0.019)
and the period of tamoxifen treatment in switch regimens were shorter. Conclusion: The results of this study suggested that, high risk breast cancer patients with
involvement of five and more nodes that have the predictive factors as grade 3 and/or
p53 negative tumors are propably more responsive to adjuvant treatments. Chemotherapy
of more than 6 cycles, administering taxane based regimens and aromatase inhibitors
in the adjuvant regimens may favourably effect the prognosis.
Fusion of Infrared Thermal Image and Visible Image for 3D Thermal Model Reconstruction Using Smartphone Sensors

Published: May 2018

Thermal infrared imagery provides temperature information on target objects, and has been widely applied in non-destructive testing. However, thermal infrared imagery is not always able to display detailed textures of inspected objects, which hampers the understanding of geometric entities consisting of temperature information. Although some commercial software has been developed for 3D thermal model displays, the software requires the use of expensive specific thermal infrared sensors. This study proposes a cost-effective method for 3D thermal model reconstruction based on image-based modeling. Two smart phones and a low-cost thermal infrared camera are employed to acquire visible images and thermal images, respectively, that are fused for 3D thermal model reconstruction. The experiment results demonstrate that the proposed method is able to effectively reconstruct a 3D thermal model which extremely approximates its corresponding entity. The total computation time for the 3D thermal model reconstruction is intensive while generating dense points required for the creation of a geometric entity. Future work will improve the efficiency of the proposed method in order to expand its potential applications to in-time monitoring.

Grupo de sociedades y reconocimiento de créditos en el concurso de acreedores de alguna de las sociedades del grupo
Authors: Espigares Huete José Carlos
Published: May 2018

A los efectos de la Ley Concursal se entenderá por grupo de sociedades lo dispuesto en el artículo 42.1 del Código de Comercio. Esta remisión de la Disposición adicional sexta de la Ley Concursal (introducida por el número ciento catorce del artículo único de la Ley 38/2011, de 10 de octubre, de reforma de la Ley 22/2003, de 9 de julio, Concursal) permitió aligerar la cuestión de la definición de grupo societario en esta sede. Y no era poca cosa, porque la remisión condicionaba cuestiones varias de una repercusión práctica evidente. Es el caso, por ejemplo, del serial de personas especialmente relacionadas con el deudor concursado (art.93 LC), la eventual tramitación coordinada del concurso para las sociedades de un grupo (arts. 25, 25 bis y 25 ter LC), las incompatibilidades que afectan a la designación del cargo de administrador concursal (art.28.1 LC), las presunciones de perjuicio patrimonial en las acciones de reintegración (art.71.3.1º LC) o la subordinación de créditos en el concurso (art.92.5ºLC).
Primeras impresiones sobre la resolución de la Sala de Competencia de la Comisión Nacional de los Mercados y de la Competencia (CNMC) de 13 de febrero de 2018 en el expediente S/DC/0579/16
Authors: Martín Baumeister Bruno
Published: May 2018

Resumen: En su resolución de 13 de febrero de 2018 la CNMC sanciona a cuatro entidades de crédito por infracción muy grave del artículo 1 de la Ley de Defensa de la Competencia (LDC) así como del artículo 1 del Tratado sobre el Funcionamiento de la Unión Europea (TFUE) por actuación concertada en la fijación de precios por encima de las condiciones de mercado en los derivados extrabursátiles utilizados como cobertura del riesgo de tipo de interés en préstamos sindicados en financiación de proyectos. La CNMC acepta que ni la fijación del precio de los tipos floor y swap ‘en condiciones mercado’ o con ‘coste cero’ ni tampoco –aunque con algunas dudas– la fijación de dichos tipos con un margen (spread) representan una conducta prohibida del apartado 1 de los artículos 1 LDC y 101 TFUE. Sin embargo, la determinación de un precio de los tipos superior al precio que hubiera derivado de su fijación en condiciones de mercado es ilícita cuando se realiza con desconocimiento de la parte financiada, lo que representa una restricción por objeto en forma de infracción única y continuada en el tiempo en el sentido del artículo 1 LDC y del artículo 101 TFUE.Palabras clave: Crédito sindicado; derivado de cobertura de tipo de interés; práctica colusoria.

Del Uti Possidetis iure a la corte internacional de la Haya: la decadencia de la diplomacia colombiana en la defensa del territorio
Authors: Acevedo Vélez John Jairo
Published: May 2018

Objetivo: está en el orden de analizar desde el ámbito de la historia política de Colombia y las relaciones internacionales la fragmentación del territorio nacional derivado de una política exterior débil acompañada de una diplomacia politizada que ha debilitado el Estado. Método: Estudio histórico hermenéutico que busca indagar la evolución histórica del territorio colombiano a partir de fuentes primarias como la prensa del siglo XIX y publicaciones académicas especializadas que estudian la controversia limítrofe entre Colombia y Nicaragua. Resultado: La diplomacia colombiana ha actuado frente a falsos sofismas de corte democrático e internacional, socavando la soberanía nacional frente a intereses geopolíticos y geoestratégicos que han fracturado la unidad territorial que a lo largo de doscientos años de independencia el Estado colombiano ha sido pasivo frente a intereses de Estados que buscan desconocer la larga tradición y soberanía sobre sus territorios derivados de cédulas reales que legitima su posesión y dominio territorial. Conclusiones: El Estado social de derecho, en el marco de su política exterior, evidencia una política internacional débil por la carencia de una escuela diplomática que defienda los intereses de Colombia en el concierto internacional y frente a instancia judiciales como la Corte de la Haya.

La movilidad urbana se ha convertido en uno de los temas de mayor interés para la academia y la institucionalidad pública, pues coinciden que son múltiples los retos y desafíos para su eficiente intervención. Parte de las investigaciones han girado en torno al estudio de movilidad eficiente, medio ambiente y propuestas para mejorar los sistemas de movilidad urbana. Otro grupo se ha centrado en el análisis del alcance de la intervención estatal, dejando de lado el estudio de otras variables como la percepción de la ciudadanía, que permita caracterizar su ideal de movilidad. En ese sentido la percepción de la ciudadanía permite identificar los principales problemas a resolver frente a la Movilidad Urbana, para así, tener en cuenta las posibles soluciones planteadas por la ciudadanía y servir de insumo para futuras intervenciones que faciliten los desplazamientos, la eficacia del transporte público, las alternativas de movilidad y la educación vial. De esta manera, para analizar la percepción de la ciudadanía de Popayán se acudió al diseño metodológico de tipo cuantitativo mediante la realización de un sondeo y complementado por el análisis documental a partir de la revisión de prensa local, permitiendo colegir que el mejoramiento de la movilidad debe estar articulado a alternativas de diferente tipo.
