ADENOMA SUPRARRENAL PRODUCTOR DE ALDOSTERONA: REPORTE DE UN CASO DE HIPERALDOSTERONISMO PRIMARIO
Authors: Pérez Fernando
Published: September 2020

El Hiperaldosteronismo Primario es una entidad clínica caracterizada por una producción autonómica excesiva de aldosterona, independiente del sistema renina-angiotensina-aldosterona, su regulador fisiológico. La presentación clínica más común del hiperaldosteronismo primario es la hipertensión resistente, la cual puede estar asociada en algunos casos a hipokalemia y alcalosis metabólica. El 10% de los casos de hipertensión secundaria se encuentra asociado a hiperaldosteronismo primario, en donde el 50% de las veces se debe a un adenoma suprarrenal productor de aldosterona, un tumor benigno de la glándula suprarrenal el cual típicamente es unilateral y es una de las excepcionales causas curables de hipertensión. Jerome Conn describió esta entidad, su diagnóstico y tratamiento por primera vez en el año 1955. Se presenta el caso de un paciente masculino de 53 años con antecedente de hipertensión arterial de 11 años de evolución de difícil control, quien es estudiado por presentar calambres musculares, fatiga e hipokalemia. Ante la sospecha clínica de hiperaldosteronismo primario se realiza la prueba del cociente aldosterona:renina plasmática, en donde se encuentra una relación elevada. Se le realiza una adenalectomia laparoscópica posterior al hallazgo por tomografía computarizada contrastada de una lesión nodular de centro hipodenso de 1 cm en la glándula suprarrenal derecha. El estudio histopatológico confirma el diagnóstico. El paciente no ha vuelto a presentar cifras de hipertensión arterial después de la cirugía razón por la cual se le suspende la medicación antihipertensiva.

Max Weber ja Euroopan Unioni
Authors: Palonen Kari
Published: September 2020

Emeritusprofessori Kari Palonen avaa Max Webein yhteyttä Euroopan Unioniin. Koska Weber kuoli espanjantautiin kesäkuussa 1920, hänellä ei kuitenkaan voinut olla mitään käsitystä Euroopan unionista, sellaisena kuin me sen tunnemme. Palonen lähestyykin Euroopan Unionia Weberin ajatusten kautta, joissa esimerkiksi ymmärretään toteutuneita mahdollisuuksia vertaamalla niitä toteutumattomiin. Palonen ei myöskään ole ainoa Weber-tutkija, joka on pohtinut Weberin suhdetta Euroopan integraatioon.

ABSTRACTIn the current condition, the Covid-19 pandemic has an impact that is enough to make everyone feel distress until the government really carries out regional autonomy appropriately. The Covid-19 pandemic is not over and causes a lot of adversity, especially for the community both in terms of income and social aspects. This study aims to 1) analyze the regional policies that have been applied in dealing with a pandemic 2) Look at the influence of local policies on the socio-economic conditions of the community. The method used in this study is the analytical descriptive method approach. The data used are analytic qualitative data and literature literature study. Based on the results and discussion in this study, regional autonomy policy allows regional governments to freely apply large-scale social restrictions with quarantine or temporary lockdown in order to stop covid-19 transmission. Local government policy has a significant influence on the handling of Covid-19 due to the potential potential of workers who stop working as much as 16% so that the government reopens economic places such as the market as an effort to improve the economy and the welfare of the community who are sinking while continuing to implement health protocols.

Diversificación de exportaciones: ¿es Chile diferente a Australia y Nueva Zelanda?
Authors: González Hermann , Larraín Felipe , Perelló Óscar
Published: September 2020

Este trabajo analiza el grado de diversificación de la economía chilena en relación con Australia y Nueva Zelanda durante el período 1990-2018, utilizando datos de exportaciones desagregados y distintas medidas de concentración. Australia y Nueva Zelanda se desarrollaron en un período reciente, comparten características estructurales con la economía chilena y, cuando tenían el nivel de ingreso de Chile, tenían mayores similitudes con la economía chilena que otros países que podrían usarse como modelo de desarrollo. Nuestros principales resultados indican que (i) Chile tiene un grado de concentración de exportaciones equivalente o inferior al de Australia, de acuerdo con la medición que se considere, pero superior al de Nueva Zelanda; (ii) el grado de concentración actual en Chile es similar al que tenía en 1990, a pesar del aumento observado durante el ‘superciclo’ de las materias primas; (iii) Australia y Nueva Zelanda han aumentado la concentración de sus exportaciones a lo largo del tiempo, lo cual estuvo asociado a una mayor participación de sus productos ‘tradicionales’. La experiencia de Australia y Nueva Zelanda sugiere que la diversificación hacia bienes de mayor sofisticación económica no es una condición necesaria para el desarrollo de Chile, mientras que la evidencia económica sugiere enfocar la política comercial hacia potenciar el sector exportador y no tener la diversificación de exportaciones como un objetivo en sí mismo. Finalmente, se discuten políticas públicas alternativas, como potenciar la diversificación dentro del sector de recursos naturales e impulsar las exportaciones de servicios.

Authors: Machado Vinicius , Machado Pedro Leineker Ochoski , Machado Vitor Otávio Ochoski
Published: September 2020

O presente artigo apresenta relato do ensaio de uma atividade experimental desenvolvida para o ensino de Física em cursos de Engenharia em um laboratório didático de Física. Nessa atividade buscou-se determinar por dois métodos distintos o momento de inércia de um disco cilíndrico oco com eixo perpendicular à sua face plana e situado em seu centro de massa. Em um dos métodos determinou-se o momento de inércia a partir do uso de sua equação própria. No outro método utilizou-se da equação do torque, grandeza responsável pelo impulso angular provocado sobre o disco. Ao final da atividade os valores obtidos em cada metodo foram comparados por meio do cálculo de percentual de erro e obteve-se o resultado de 2,26% para a média dos tempos medidos e zero% para um valor específico entre os tempos medidos.

Authors: Machado Vitor Otávio Ochoski , Peres Pedro Elias Muniz , Parise Maria Regina , Behainne Jhon Jairo Ramírez
Published: September 2020

Apresenta-se, neste trabalho, um estudo sobre o comportamento fluidodinâmico do escoamento interno gás-sólido em um ciclone com entrada tangencial, acoplado a um leito fluidizado circulante, em função da variação do coeficiente de especularidade associado à interação das partículas com as superfícies do separador. Para isso, o método dos volumes finitos foi aplicado por meio do programa computacional ANSYS®Fluent®v. 19.2, a fim de resolver as equações governantes do escoamento multifásico descrito pela abordagem Euleriana-Euleriana com o uso da Teoria Cinética do Escoamento Granular (KTGF). Os modelos de Gidaspow, Schaeffer e k-epsilon foram empregados para traduzir os efeitos do arrasto, da viscosidade friccional e da turbulência, respectivamente. Os resultados das simulações foram confrontados com dados experimentais de pressão estática e da eficiência de separação de partículas em um ciclone de mesma geometria, conectado a uma unidade de leito fluidizado circulante em escala de laboratório e operada em condições atmosféricas.
Evaluation of the quality of the shielded metal arc welding process using speckle interferometry
Authors: Prado Felipe Maia , Toffoli Daniel José , Da Silva Sidney Leal
Published: September 2020

Speckle, which is a branch of optics that studies the interference pattern caused by the incidence of coherent light in a material’s surface, has some optical techniques and methods that can be successfully applied to determine properties of materials. In this work we used the method called THSP, Time History Speckle Pattern, in samples made of AISI 1020 carbon steel that were submitted to the shielded metal arc welding (SMAW) process, with the objective of identifying (qualitatively) the level of irregularity on its welded surface, by comparing these samples with a default sample, made with the same material. The technique of spekle by reflection was used for data collection. The results showed quantitative diferences between the default welded sample and the other samples, and there are good perspectives that speckle can be applied to determine the quality of the welding process, since the results showed more accuracy than visual inspection.
Relações da termoquímica via formas diferenciais exterior: aplicação em células galvânicas
Authors: A. B. da Silva Jr Carlos , Filardo Bassalo José Maria , Valente Zínia de Aquino
Published: September 2020

Este trabalho é uma extensão dos artigos de Bassalo e Cattani (1999) e Bassalo, Valente e Cattani 2000) que tratam das aplicações da Termodinâmica via relações de Maxwell usando formas diferenciais exterior para sistema PVT. Na tentativa de tornar a Termodinâmica mais familiar, este trabalho apresenta as relações da Termoquímica, que inclui as Relações de Maxwell aplicadas a um sistema eletroquímico, tal como a célula galvânica (ou pilha). Para tanto, os conceitos e as formulações matemáticas são baseados na Termodinâmica e nas formas diferenciais exterior que podem ser explorados em um curso de graduação do ponto de vista da Físico-Química e da Termodinâmica. Uma grande vantagem do tratamento dos problemas físicos via forma diferencial exterior comparado aos diagramas mnemônicos e as derivadas parciais é que: 1- um número maior de relações de Maxwell pode ser obtido, como aplicação a célula galvânica; 2- elas generalizam como tensores, porém com a simplicidade dos vetores.
Vortex generators project for an unmanned small airplane
Authors: Duarte Neto João Barreto , Martinez Maria Elisa Marciano , Reis Marcello Carvalho dos , Wehmann Claus Franz
Published: September 2020

Since the Cold War period, turbine generators have proved to be an important alternative to the development of aerodynamic aircraft designs, and even so, there was little adherence to their use, among which we highlight, short takeoff and landing aircraft (STOL) and some models of military aircraft and commercial jet aircraft. In the USA and Brazil, in addition to other countries, they hold competitions to awaken technological innovation in the aeronautical field for engineering students: the SAE AeroDesign Competition (SAE - Society of Automotive Engineers). These contests allow teams from their countries to use points of difference in their design and, in some cases, to use small unmanned aircraft devices that have already been designed for huge aircraft, such as vortex generators. Therefore, we intend to adopt a Vortex Generator model for the Avoante Aeromec AeroDesign team airplane project (team from the Federal University of Ceara, Brazil - UFC), use Computational Fluid Dynamics (CFD) with turbulence modeling, as well as perform tests in a wind tunnel. Despite the problems found in comparing the results of the computational models with the prototype tests, it was possible to prove the efficiency of these vortex generators in the design of the team's airplane, observing the increase in the stall angle, reduction of the drag coefficient and increase of the coefficient lifting.

Published: September 2020

A fragilidade ambiental é uma das ferramentas de estudos que permitem compreender e visualizar áreas vulneráveis ou não aos processos erosivos, e quando aliada ao uso impróprio dos recursos hídricos e ambientais potencializam os desastres naturais. Diante desse contexto, o objetivo do trabalho foi caracterizar a fragilidade ambiental da sub-bacia do rio Congonhas, MG, localizada entre os municípios de Grão Mogol e Itacambira, e tendo como projeto futuro a construção da barragem de Congonhas. A análise foi construída a partir do modelo SRTM (Shuttle Radar Topography Mission), dados oficiais e uma imagem de satélite Sentinel-2, e integradas ao ambiente SIG obteve as variáveis ambientais que influenciam nos processos erosivos. Através de informações de pluviosidade, declividade e tipos de solos da área gerou-se o Mapa de Fragilidade Potencial (MFP) e a partir da combinação deste mapa com as informações de uso e ocupação do solo obteve-se o Mapa de Fragilidade Emergente (MFE). Verificou-se que a maior parte da região possui nível de fragilidade (potencial e emergente) nas classes médias a muito forte. Já as áreas de média fragilidade ambiental ocupam 25,54% (MFP) e 18,88% (MFE) e as áreas de baixa fragilidade correspondem a 36,73% (MFP) e 32,55% (MFE). O modelo produzido gerou informações importantes para a gestão ambiental e planejamento territorial para futuros projetos governamentais, municipais e sociedade civil, incentivando o uso racional dos recursos naturais e principalmente, o monitoramento das áreas instáveis.
Ciência-tecnologia-sociedade: dos fundamentos histórico-ontológicos aos princípios analíticos
Authors: Oliveira Loryne Viana
Published: September 2020

O presente estudo, de natureza bibliográfica, tem por objetivo passar em revista os sentidos e perspectivas das relações entre Ciência, Tecnologia e Sociedade – CTS, com a finalidade de caracterizar e sintetizar princípios teórico-analíticos do campo CTS. Tomou-se, como fio condutor, uma reflexão conceitual e histórica sobre o que sejam tais relações e como foram encaradas ao longo do tempo. Para tanto, procedeu-se à caracterização destas relações na Idade Antiga, com o surgimento da técnica e sua dimensão ontológica, na qual as relações entre CTS eram elididas por uma compreensão, sobretudo de ascendência platônica – para qual a técnica e em algum sentido, a tecnologia, seriam inferiores ao saber teórico. Em seguida, na modernidade, quando o desenvolvimento destas percepções institui o paradigma da ciência moderna, autônoma, livre de valores e neutra; para então situar a emergência dos Estudos Sociais sobre Ciência e Tecnologia, percorrendo o pensamento de Robert Merton, Thomas Kuhn e outros. Analisa-se, em seguida, os pressupostos teóricos do Programa Forte da Sociologia do Conhecimento, seminais para o Programa Empírico do Relativismo e para a Construção Social da Tecnologia. O artigo finaliza apresentando o que há de estrutural na reflexão empreendida desde os Estudos Sociais da Ciência e da Tecnologia, isto é, seus princípios teórico-analíticos.

Avaliação sistêmica de tolerância a falhas em sistemas de proteção de reatores nucleares
Authors: Busse Alexander Lucas , Moreira João Manoel Losada , Ozeki Tatiana Yuri Boncristiano , Da Silva Luis Geraldo Gomes
Published: September 2020

O conceito de tolerância a falhas tornou-se importante nas últimas décadas na indústria nuclear devido à utilização de sistemas de Instrumentação e Controle (I&C) digitais. Uma falha é uma anomalia indesejada em um item ou sistema que pode levar a um estado inseguro e eventualmente gerar incidentes ou acidentes de consequências indesejáveis do ponto de vista socioambiental. Atualmente as soluções digitais são muito atraentes, não obstante, requererem avaliações de software quanto a tolerância a falhas. Nosso artigo pretende realizar uma investigação teórica de confiabilidade e taxa de falha, com base em um Diagrama de Blocos de Confiabilidade, em um sistema de proteção digital para reatores nucleares. Adicionalmente, discute sobre a necessidade de cultura de segurança nos segmentos de operação do reator, monitoramento e fiscalização para garantir que eventos acidentais indesejados sejam evitados.

The article represents an overview of 29 biological species of the radicine snails (generaAmpullaceanaServain, 1882,BullastraBergh, 1901,RacesinaVinarski & Bolotov, 2018,KamtschaticanaKruglov & Starobogatov, 1984,MyxasG.B. Sowerby I, 1822,OrientogalbaKruglov & Starobogatov, 1985;PeregrianaServain, 1882,RadixMontfort, 1810, andTibetoradixBolotov, Vinarski & Aksenova, 2018) recovered during our previous molecular taxonomic study (Aksenova et al. 2018a; Scientific Reports, 8: 11199). For each species, the following information is provided: scientific name, a (non-exhaustive) list of synonyms, type locality, type materials, shell and copulative apparatus morphology, distribution, and nomenclatural and taxonomic remarks. The colour images of shell(s) of each species are also given as well as illustrations of the copulatory apparatuses. We revealed a great conchological variation in the radicines, both intra- and interspecific, alongside with striking uniformity in the structure of their copulatory apparatuses. The latter was once thought to be a reliable tool for species delineation and identification in this snail group. The total of 29 species characterised here represents, probably, only a subset of the global taxonomic richness of the radicine snails, which approaches 50 species.

Published: September 2020

Oritrophium (Kunth) Cuatrec. is a neotropical genus with a disjunct distribution in the Andes (Bolivia, Colombia, Ecuador, Peru, and Venezuela), the center of Mexico, and the mountains of the Guiana Shield in Venezuela, with a remarkable diversity in Ecuador. We present a taxonomic study for Ecuador that represents the first modern and exhaustive revision of this genus in this country. We recognize eight species and four subespecies. We provide a dichotomous key, descriptions, synonyms, morphological and nomenclatural notes, distribution maps, and photographs of living plants. Three names are lectotypified and two names are neotypified.
Tecnología andina y española: Características constructivas de la torre de adobe de la iglesia virreinal San Cristóbal de Huánuco, Perú
Authors: Hurtado-Valdez Pedro
Published: September 2020

La presencia de alarifes españoles en Perú durante el siglo XVI dio inicio al empleo de técnicas constructivas novedosas en los Andes. Pronto se observó que dichas técnicas no soportaban fenómenos sísmicos frecuentes y de elevadas magnitudes muy comunes en estas tierras. Los maestros constructores estudiaron la tecnología andina y adaptaron la arquitectura española a las características sísmicas del nuevo territorio ante los persistentes daños ocasionados por los terremotos en sus edificaciones. El presente trabajo analiza las características constructivas de los edificios construidos en los Andes centrales de Perú, como fruto de un mestizaje constructivo para mejorar el desempeño de sus estructuras, a partir del relevamiento y análisis del colapso de la torre construida con adobe en la iglesia de San Cristóbal en Huánuco-Perú.

A 70-year-old man presented to the emergency department with blood hypotension associated to a sudden paraplegia and thermalgesic analgesia. He had an history of colic and prostatic adenocarcinoma, hypertension and non-dialyzed Chronic Kidney Disease (CKD) related to an idiopathic membranous glomerulonephritis type 1 discovered 9 years ago. Magnetic resonance imaging confirmed a diagnosis of Spinal Cord Infarction (SCI). Few months later, he presented a blurred vision due to central Retinal Vein Occlusion (RVO), which was improved by Anti-VEGF therapy. This is the first reported case of a concomitance of retinal vascular event and SCI highlights the links between the central nervous system and retinal vascularization despite separate involvement of the two events in the arterial and venous systems. Additionally, CKD worsened the risk of cardiovascular incidents by induced oxidative stress, thrombophilia, chronic inflammation, and endothelial dysfunction. SCI occurrence indicates severe vascular dysfunction and elevates the risk of additional vascular disorders.
The author's arsenal: loosening standards for protectability and substantial similarity in video game copyright
Authors: Brown Oliver
Published: September 2020

This article examines and critiques the American copyright regime's increasingly protective approach to video games and their subject matter. Over the past decade, a trio of district court decisions have bolstered protection for video games by relaxing standards for protectability and substantial similarity. Subsequent rulings, concerning both games and other forms of intellectual property, suggest this protective streak will continue. While heightened protection might provide a necessary deterrent to ‘cloning’ and other kinds of impermissible copying, it will also endanger valuable forms of appropriation. After decades of limited copyright involvement, mimesis has become an important element of game creation – widely tolerated by the gaming community as a source of inspiration, interoperability, and cultural conversation. A more expansive view of protectability may inhibit imitative behavior that has, in the past, benefited new creators and fans without harming the economic expectations of prior authors. Moreover, that new approach, which relies heavily on juries for unpredictable, case-by-case determinations, may restrict the financial and creative outlook of the video game industry at large.

In its first section, this article identifies the elements of video games that have been deemed protectable under copyright law. The second section summarizes foundational video game case law, in which courts established restrictive standards for protectability and substantial similarity. The third then discusses the paradigm shift towards more expansive protectability, recounting cases where courts found games worthy of heightened protection. In its fourth section, this article argues that the protective trend has yet to peak, looking to evidence gleaned from recent copyright suits. A concluding section outlines the risks of overprotection, cautioning against a potentially unreasoned and impractical copyright standard.
Digital advertising: regulations and challenges in Russia
Authors: Shurmina Irina
Published: September 2020

Advertising on the Internet showed fascinating results in Russia in 2019 – according to the statistics of the Association of Communication Agencies of Russia (ACAR), the Internet was the only growing platform of advertising distribution, while such channels as TV, radio and printed media shortened their advertising profits. Along with growth of the online advertising market the interest and attention to legal aspects of digital advertising is increasing. Cases on digital advertising are always creative just like advertising itself is. The main challenges relate to the application of regular requirements of the advertising law, which are already well understood in the TV or radio business, to the Internet. While doing this, we in Russia also take into account international experience and trends in the field of digital advertising and try to predict further development of legal landscape and practice.

In Indian freshwater fish myxosporean infections are among the most cosmopolitan parasites, they are relatively well studied morphologically but their phylogenetic relationships were unclear and the genetic data is limited only to a few species. The study aims to present molecular data for two myxosporean species, Henneguya namae Haldar et al. 1983 and Myxobolus sophorae Jayasri, 1982 collected from Indian freshwater fish, the elongate glass-perchlet Chanda nama (=Ambassis nama) and pool barb Puntius sophore, respectively. In the present study molecular data are provided for H. namae and M. sophorae using nested PCR. The obtained partial 18S rDNA gene sequences were analyzed using maximum likelihood (ML) and Bayesian inference (BI) methods. The 18S rDNA gene sequences of H. namae showed similarity with the sequences of H. chaudhuryi, Henneguya sp. RA-2015, H. voronini and H. setiuensis about 72.1 to 78% and M. sophorae with Myxobolus ticto was about 90% respectively. The aim of this paper was to identify H. namae and M. sophorae morphologically and using molecular methods.

Knowledge of the microbial diversity on hospital bed linens has implicit significance for infection control because bed linens are likely reservoir and vehicles for healthcare-associated Infections (HAIs). In this study, the diversity of microorganisms that persist on bed linens at Benue State University Teaching Hospital (BSUTH), Makurdi, Nigeria was evaluated. Patients’ bed and surface areas on bed linens were chosen at random from ten different wards and the swab sampling method employed. Of the 30-bed linens sampled, bacteria were more prevalent at 63.3%, and fungi at 34.48%. We identified both bacteria and fungi from eight wards, only fungi from the antenatal ward and no contamination from the amenity ward. Staphylococcus aureus, Escherichia coli, Klebsiella, and coagulase-negative Staphylococcus dominated the bacterial profile. Similarly, Aspergillus niger, Candida albicans, and Microsporium ferrugenium fungi were also recovered from the bed linens. Amongst the bacteria identified, Escherichia coli gave the highest prevalence at 36.84%, whereas, Candida albicans revealed the highest among the fungi isolates with 50%. Chi-square analysis showed a significant relationship (χ2 = 68.48, df =8, P<0.05) between the microbial contamination and the wards sampled. The mean bacterial count (cfu/ml) was checked for each ward and the female surgical ward showed the highest count of 31.3 × 103 and the paediatric ward had the least count of 2.3 × 103. Control beddings were also contaminated with 1.3 × 103. These results suggest that the bed linens from the hospital wards were contaminated with pathogenic microbes which can contribute to HAIs.

This study pretends to verify the attending with the practices stipulated by the National Solid Waste Policy (PNRS) Law No. 12,305 of August 2010, mainly when it comes to the verification of the availability of information in websites of computer manufacturers. As a research methodology, the availability of aspects related to Reverse Logistics (LR) was adopted through research in the electronic sites of computer manufacturers, with the application of a research protocol. The research was conducted between October and November 2017, the results presented show that computer manufacturers are still very distant from the compliance of PNRS, and only one of them had a performance considered good, regarding the commitment to the availability of information pertinent to the PNRS. Another aspect observed by the study reflects the low concern with LR, being that the last criterion pondered, in the statistics. The results presented show the need for great advances, improvement processes, thinning of methods and a more real and assertive commitment of computer manufacturers to the establishment of PNRS.
