The marine macroalgae of Cabo Verde archipelago : an updated checklist

An updated list of the names of the marine macroalgae of Cabo Verde, an archipelago of ten volcanic islands in the central Atlantic Ocean, is presented based on existing reports, and includes the addition of 36 species. The checklist comprises a total of 372 species names, of which 68 are brown algae (Ochrophyta), 238 are red algae (Rhodophyta) and 66 green algae (Chlorophyta). New distribution records reveal the existence of 10 putative endemic species for Cabo Verde islands, nine species that are geographically restricted to the Macaronesia, five species that are restricted to Cabo Verde islands and the nearby Tropical Western African coast, and five species known to occur only in the Maraconesian Islands and Tropical West Africa. Two species, previously considered invalid names, are here validly published as Colaconema naumannii comb. nov. and Sebdenia canariensis sp. nov.The present work was generated in the context of the Project PADDLE - Planning in the liquid world with tropical stakes, funded by the European Union’s Horizon 2020 Research and Innovation Programme under Grant 734271.

Warty carcinoma of uterine cervix - review of the literature and case report

Introduction. The Histological Classification of Epithelial Tumors of the Uterine Cervix of the World Health Organization includes inter alia warty carcinoma as a variant of squamous cell carcinoma. Until now several case reports and studies have shown that this particular cancer is associated with human papillomavirus/ HPV infection. Case presentation. A 58-year-old woman presented with a vegetant cervical tumour. Biopsy samples were collected from the tumour, and the histological exam successively confirmed the warty cell carcinoma. Additional tests revealed the presence of single human papillomavirus/ type-45. An immunohistochemistry exam was performed in order to confirm the diagnosis, and also to highlight the relationship between the potential causal factors and the morphological appearance. This allowed the confirmation of the diagnosis, and added new elements able to define the characteristics of this form of cancer. The treatment included radiotherapy and radical hysterectomy with anexectomy, and pelvic lymphadenectomy. The evolution was favorable, with no signs of local recurrence or metastasis in the past five years. Conclusions. Warty carcinoma, relatively similar to condyloma acuminatum or verrucous carcinomas, has specific immune-histochemical features that differentiate it from other variants of squamous cell carcinoma. The HPV genotype 45 can be considered a causative factor in the pathogenesis of cervical warty carcinoma. Even so, warty carcinoma appears not to be caused by a specific HPV subtype (or a combination of several specific genotypes), being rather a multifactorial affection

Evolutionary processes and its environmental correlates in the cranial morphology of western chipmunks (Tamias).

The importance of the environment in shaping phenotypic evolution lies at the core of evolutionary biology. Chipmunks of the genus Tamias (subgenus Neotamias) are part of a very recent radiation, occupying a wide range of environments with marked niche partitioning among species. One open question is if and how those differences in environments affected phenotypic evolution in this lineage. Herein we examine the relative importance of genetic drift versus natural selection in the origin of cranial diversity exhibited by clade members. We also explore the degree to which variation in potential selective agents (environmental variables) are correlated with the patterns of morphological variation presented. We found that genetic drift cannot explain morphological diversification in the group, thus supporting the potential role of natural selection as the predominant evolutionary force during Neotamias cranial diversification, although the strength of selection varied greatly among species. This morphological diversification, in turn, was correlated with environmental conditions, suggesting a possible causal relationship. These results underscore that extant Neotamias represent a radiation in which aspects of the environment might have acted as the selective force driving species' divergence

A Simulation Model for Logical and Operative Clash Detection

The introduction of the Building Information Modeling (BIM) approach has facilitated the management process of documents produced by different kinds of professionals involved in the design and/or renovation of a building, through identification and subsequent management of geometrical interferences (Clash Detection). The methodology of this research proposes a tool to support Clash Detection, introducing the logical-operative dimension, that may occur with the presence of a construction site within a hospital structure, through the integration of a BIM model within a Game Engine environment, to preserve the continuity of daily hospital activities and trying to reduce negative impacts, times and costs due to construction activities

Relações bilaterais entre Argentina e China: aliança estratégica ou dependência?

Anais do IV Encontro de Iniciação Científica da Unila - “UNILA 5 anos: Integração em Ciência, Tecnologia e Cultura na Tríplice Fronteira” - 05 e 06 de novembro de 2015 – Sessão Relações InternacionaisA aproximação bilateral entre Argentina e China nos últimos anos, juntamente com os acordos de cooperação firmados no começo de 2015 e os seus possíveis impactos para a matriz econômica argentina, são pontos que tem gerado debates em torno do modelo de desenvolvimento escolhido pela argentina nos últimos anos. Na pós­conversibilidade, a Argentina aprofundou a presença de capital transnacional em relação ao período dos anos noventa. Com um cenário industrial fragilizado, devido aos anos de conversibilidade, o país continua sendo um grande exportador de commodities agrícolas e minérios e dependente dessa fonte de recursos externos. Com a ascensão do capital chinês no cenário internacional, como grande financiador e consumidor, fizeram com que as relações da China com a Argentina e com outros países latino­americanos fossem fortalecidas nos últimos anos, devido a busca chinesa por commodities agrícolas e minérios. O presente trabalho tem como objetivo analisar se as relações entre os dois países condicionarão a matriz econômica argentina a uma dependência estrutural, que poderá afetar o desenvolvimento nacional ou se essas relações promoverão cenários estratégicos para o desenvolvimento nacional.Voluntári

Integración educativa en el MERCOSUR: el problema de la revalidación de diplomas universitários

O CONGRESSO DE INTERNACIONALIZAÇÃO DA EDUCAÇÃO SUPERIOR – CIES 2019 é um evento in- ternacional, que reúne professores, pesquisadores e estudantes de graduação e pós-graduação para divulgar a produção científica no campo da Internacionalização do Ensino Superior e fortalecer a cooperação internacional entre diferentes instituições de ensino e grupos de pesquisa no âmbito do MERCOSUL. A iniciativa é fruto de uma parceria entre pesquisadores da Universidade Federal da Integra- ção Latino-Americana (UNILA - Brasil), a Universidad Nacional del Litoral (UNL - Argentina), a Uni- versidad Nacional de Asunción (UNA - Paraguay) e a Universidad de la República (UDeLaR - Uru- guay), que atuam em projetos vinculados ao Setor Educacional do MERCOSUL, no Núcleo de Estudos e Investigações em Educação Superior. O evento será realizado nos dias 4, 5 e 6 de Setembro de 2019 no campus PTI da UNILA, dentro do Parque Tecnológico da Usina Hidrelétrica de Itaipu, na cidade de Foz do Iguaçu, Paraná, Brasil. A UNILA, sede do evento, é uma universidade temática criada em 2010 pelo governo federal do Brasil com a missão institucional de formar recursos humanos aptos a contribuir com a integra- ção latino-americana, com o desenvolvimento regional e com o intercâmbio cultural, científico e educacional da América Latina, especialmente no MERCOSUL. Sua finalidade, portanto, é conver- ter-se em um espaço de encontros, de trocas e de aprendizagem mútua, que reforçam o compro- misso em prol da pertinência, da excelência e da construção sustentável de um mundo melhor.El Mercado Común del Sur (MERCOSUR) es un proyecto de integración de alcance subregional que nació en 1991 tras la firma del Tratado de Asunción por parte de Argentina, Brasil, Paraguay y Uruguay. Si bien este bloque se desarrolló en los hechos como una unión aduanera, algunas investigaciones señalan que el Tratado de Asunción contenía una serie de ideas para alcanzar una integración profunda, lo cual le daría al MERCOSUR cierta versatilidad frente a los cambios políticos y económicos en la región y sobrevivir a ellos. Estas características se habrían expresado, además, en las agendas sociales de integración, las cuales tuvieron mayor preponderancia en el periodo 2003-2012, etapa donde se produjo el relanzamiento de los procesos de integración (Peixoto Batista y Perrota, 2018). De estas agendas sociales de integración, nos interessa examinar el caso de la integración educativa, abordando, principalmente, los mecanismos y limitaciones para el reconocimiento y la revalidación de títulos universitarios. También se analiza el Sistema de Acreditación Regional de Carreras Universitarias (ARCU-SUR), entidad encargada de ejecutar la evaluación y acreditación de carreras universitarias, el cual puede llegar a constituir una alternativa a la revalidación de diplomas universitarios.Núcleo de Estudios e Investigaciones en Educación Superior del Mercosur - NUCLEO Grupo Interdisciplinar de Pesquisa em Educação na América Latina – EducAL/UNILA Instituto Mercosul de Estudos Avançados – IMEA/UNILA Pró-Reitoria de Relações Institucionais e Internacionais – PROINT/UNIL

Movimientos Sociales y conflicto: la experiencia de Argentina (1993-2012)

El conflicto social es un fenómeno que caracteriza la historia de la Argentina reciente y que se profundizó con el avance de las políticas neoliberales. Si bien la represión de la última dictadura cívico-militar (1976-1983) significó un duro golpe para los movimientos sociales de larga tradición -como el movimiento obrero y el movimiento estudiantil-, el retorno de la democracia demostró que estos actores seguían en pie. Con el final del último gobierno de facto se extendió el accionar público de nuevos sujetos ?en muchos casos de fuerte activismo en el contexto de terrorismo de Estado- que se relacionaban no sólo con los derechos humanos y el reclamo de derechos civiles sino también con las consecuencias generadas por el establecimiento progresivo del programa neoliberal.El presente texto se propone hacer un recorrido por las situaciones de conflicto social y acción colectiva más destacadas del período 1993-2012, considerando una breve reflexión teórica sobre el concepto de movimientos sociales y analizando la evolución de los modelos de acumulación por los que atraviesa el país a partir de 1976. Estos puntos resultan claves para comprender la experiencia de los sujetos y el conflicto social en la Argentina reciente.Fil: Fernández, Paula Daniela.

Characteristics of Gravity Waves over an Antarctic Ice Sheet during an Austral Summer

While occurrences of wavelike motion in the stable boundary layer due to the presence of a significant restoring buoyancy force are rarely disputed, their modalities and interaction with turbulence remain a subject of active research. In this work, the characteristics of gravity waves and their impact on flow statistics, including turbulent fluxes, are presented using data collected above an Antarctic Ice sheet during an Austral Summer. Antarctica is an ideal location for exploring the characteristics of gravity waves because of persistent conditions of strong atmospheric stability in the lower troposphere. Periods dominated by wavelike motion have been identified by analysing time series measured by fast response instrumentation. The nature and characteristic of the dominant wavy motions are investigated using Fourier cross-spectral indicators. Moreover, a multi-resolution decomposition has been applied to separate gravity waves from turbulent fluctuations in case of a sufficiently defined spectral gap. Statistics computed after removing wavy disturbances highlight the large impact of gravity waves on second order turbulent quantities including turbulent flux calculations
