Cobalt/Lewis Acid Catalysis for Hydrocarbofunctionalization of Alkynes via Cooperative C–H Activation
Authors: Wang Chang-Sheng , Monaco Sabrina , Thai Anh Ngoc , Rahman Md. Shafiqur , Wang Chen , Yoshikai Naohiko
Published: January 2020

A catalytic system comprised of a cobalt-diphosphine complex and a Lewis acid (LA) such as AlMe3 has been found to promote hydrocarbofunctionalization reactions of alkynes with Lewis basic and electron-deficient substrates such as formamides, pyridones, pyridines, and azole derivatives through site-selective C-H activation. Compared with known Ni/LA catalytic system for analogous transformations, the present catalytic system not only feature convenient set up using inexpensive and bench-stable precatalyst and ligand such as Co(acac)3 and 1,3-bis(diphenylphosphino)propane (dppp), but also display distinct site-selectivity toward C-H activation of pyridone and pyridine derivatives. In particular, a completely C4-selective alkenylation of pyridine has been achieved for the first time. Mechanistic stidies including DFT calculations on the Co/Al-catalyzed addition of formamide to alkyne have suggested that the reaction involves cleavage of the carbamoyl C-H bond as the rate-limiting step, which proceeds through a ligand-to-ligand hydrogen transfer (LLHT) mechanism leading to an alkyl(carbamoyl)cobalt intermediate.

Authors: Machado Matías R. , Pantano Sergio
Published: January 2020

Despite the relevance of properly setting ionic concentrations in Molecular Dynamics (MD) simulations, methods or practical rules to set ionic strength are scarce and rarely documented. Based on a recently proposed thermodynamics method we provide an accurate rule of thumb to define the electrolytic content in simulation boxes. Extending the use of good practices in setting up MD systems is promptly needed to ensure reproducibility and consistency in molecular simulations.

Published: January 2020

Small-sized parts and micrometeoroids’ impacts represent an increasing threat to artificial components/structures. The damages caused by them can be fixed using e.g., mechanical fixture with epoxy adhesive. However, the repair process is costly and only intended for a temporary fixing the penetration. In order to increase the life time of the repair, an approach for a more reliable process using similar materials is needed. The objective of this work is to develop a process for repairing manmade structures in space by generating joint properties similar to the base material. In this work, two approaches for repairing complex structures were considered. The first approach aims to fill a hole using liquid aluminium phases by brazing, and the second approach aims to fill the holes by a solid-state process (friction stir spot welding). In this study, different binding mechanisms of these two approaches were analyzed preliminarily by means of mechanical and/or metallographic characterization under terrestrial, controlled atmosphere conditions. Both concepts are proven feasible under these conditions. It has been shown that it is possible to realize a good filling of the hole with the investigated materials and under selected process conditions with both presented concepts.

Toma-se como ´principal referência os inícios da rádio nos Estados Unidos. Argumenta-se que factores tecnológicos, dinâmicas econômicas, o quadro da regulamentação governamental e o conceito social de audiência são os fatores necessários para explicar essa transição assim como a forma que a rádio assumiu na sua origem.
TV UFSC - Considerações sobre a gestão de uma televisão pública em Santa Catarina
Authors: Emerim Cárlida , Crocomo Fernando Antonio
Published: January 2020

Um importante argumento que respalda a histórica dificuldade de funcionamento das emissoras públicas brasileiras está no modelo de gestão que limita os ganhos e os investimentos impactando diretamente na contratação de pessoal, equipamentos e, consequentemente, no conteúdo final. Além deste, há também a definição sobre o que é do ponto de vista constitucional uma emissora de televisão pública no Brasil. Não obstante a este processo, as televisões públicas universitárias, ligadas a uma instituição ou a um pool de universidades, desenvolvem produções e tentam, de diferentes formas, driblar os problemas. O presente artigo apresenta, através do percurso histórico, algumas fases de implantação da UFSC TV, hoje TV UFSC, que está investindo num modelo de produção considerado operacional e eficaz, que parece permitir uma continuidade implantando automatização em alguns processos e rotinas técnicas. Utilizando-se do modelo de pesquisa baseado na História Oral articulada com o modo de ação do Jornalismo, mostrar o percurso gerencial que culmina com uma proposta de permanência autônoma da emissora de televisão universitária pública na sociedade.

Re-framing Early Intervention: from a child to a teacher centred perspective in education
Authors: Vik Stine , Hausstätter Rune
Published: January 2020

This paper offers a theoretical description and discuss alternative approaches to Early Intervention (EI). The theoretical framework is based on the philosophical and educational frameworks of Hans Skjervheim and Gert Biesta. The central part of this discussion is the elaboration of different approaches in education, and how it relates to EI. It is stated that EI is historically rooted in an Anglo-American tradition where the central goal was to reduce the societal consequences of children struggling in schools and life in general. Evaluations, tests and interventions directed towards these children is at the core of this tradition. The alternative presented in this article points at an educational framework based on a European, relational centred, education framework and offers a perspective where EI is re-framed into a strategy where EI is focusing on the adult, responsible, person in the relationship.
Pytania egzystencjalne we wczesnej edukacji religijnej
Authors: Szczepska-Pustkowska Maria
Published: January 2020

The dispute on the possibility and shape of teaching religion in the public school has been going on for centuries. And although this education has found its place in school, the debate that is around them means that in the face of the challenges of pluralism, multiculturalism and multi-religiousness, it must constantly determine its status, mission, goals and tasks. There are still numerous doubts as to whether the school is at all the most appropriate place for shaping the sensitive areas of the human spirit, which is the religious worldview. The purpose of this text is to reflect on the place and role of existential questions in (Polish) early religious education. The text also asks about the dialogical nature of teaching, which is a cardinal prerequisite for philosophical inquiry in education (including religious education). For the purpose of this study, the analysis of “Basic Program of the Catechesis of the Catholic Church in Poland” from 2010 and 2018 was made.
Dorośli (i dorosłość) w pismach Janusza Korczaka
Authors: Szczepska-Pustkowska Maria
Published: January 2020

Analyzing the texts of Janusz Korczak, we focus mainly on the child (and childhood), which he put in the center of his reflections. He emphasized the importance of childhood humanity (full and not maimed), associated with it: the dignity of the child and respect for him and the world he created. The purpose of this text is to reflect on how Korczak perceived adults and adulthood and what meaning he gave them in his writings. In order to achieve such a goal, a phenomenographic analysis of the content of several leading works of Janusz Korczak was made. It seems that this topic, although not as expressive in his works as the theme of a child and childhood, is equally important, because in the care and education for centuries, children and adults face each other.

Transmission characteristics appear to be of similar magnitude to severe acute respiratory syndrome-related coronavirus (SARS-CoV) and pandemic influenza, indicating a risk of global spread.
Favela representada: disputas em torno de nomeações e significações nas páginas de jornais cariocas (1951-1954)
Authors: Krilow Letícia Sabina Wermeier
Published: January 2020

O presente artigo objetiva analisar a forma como parte da “grande imprensa carioca” - Correio da Manhã, Jornal do Brasil e Última Hora - representou as áreas habitacionais chamadas favelas durante o Segundo Governo Vargas (1951-1954). A relevância do trabalho se encontra ao considerarmos que, no pós 1945, o Brasil passou por um acelerado processo de industrialização e urbanização, entretanto, tais processos não ocorreram espontaneamente, bem como geraram diversas consequências, nem todas positivas, o que causou sérios questionamentos. Assim, quando consideramos que um dos fenômenos mais impactantes desse período foi o grande aumento das áreas habitacionais chamadas de favelas, se torna relevante analisar a forma como este espaço urbano foi representado nos jornais. Dessa formal, levando-se em consideração o grande poder de legitimação/deslegitimação de ideias que os meios de comunicação possuem, notamos que a forma pela qual a favela é representada pode interferir ou legitimar tomadas de decisões políticas – políticas públicas -, o que possibilita vislumbrar que projetos de sociedade estão sendo difundidas, estando tais representações inscritas no que Bourdieu chama de luta simbólica, evidenciando também disputas entre os referidos jornais. Por fim, para tal proposta, a metodologia utilizada é a Analise de Conteúdo

An Analysis of Financial Report on Profitability of Financial Institutions In Indonesia Stock Exchange
Authors: Santosa Slamet
Published: January 2020

This research was conducted to determine the effect of liquidity, NPL, and capital structure on the profitability of banking financial institutions on the Indonesia Stock Exchange partially and simultaneously. The research method uses a quantitative approach. Data analysis techniques used in this study were multiple regression analysis techniques. Testing research data using the classic assumption test, normality test, multicollinearity test, heteroscedasticity test, and autocorrelation test. The results showed that 1) Liquidity variables have an influence on bank profitability. This causes the customer to trust the bank in providing credit services due to the bank's ability to refinance its obligations to customers who hold their funds using current assets that are running well. 2) The NPL variable has no influence on bank profitability. This causes the amount of problem loans to be greater, causing problems, namely losses caused by the rate of return on bad loans. 3) Variable capital structure has no influence on bank profitability. This is because bank capital is not channeled to the public, thus making the capital unproductive and not producing profits for the company. 4) Simultaneously changes in liquidity, NPL and capital structure variables together have a significant effect on the profitability of banks on the Indonesia Stock Exchange.

In recent years, a constant increase of oil prices and declining reserves of coventional crude oils have produced those deposits of lights to be considered economically unattractive to be produced as an alternative way to keep the world´s oil supply volume.

Heavy oil deposits are mainly characterized by having high resistance to flow (high viscosity), which makes them diffi-cult to produce. Since oil viscosity is a property that is reduced by increasing the temperature, thermal recovery techniques -such as steam injection or in-situ combustion- have become over the years the main tool for tertiary recovery of these oils.

Composite reservoirs can occur naturally or may be artificially created. Changes in reservoir width, facies or type of fluid (hydraulic contact) forming two different regions are examples of two-zone composite reservoirs occurring naturally. On the other hand, such enhanced oil recovery projects as waterflooding, polymer floods, gas injection, in-situ combustion, steam drive, and CO2 miscible artificially create conditions where the reservoir can be considered as a composite system. A reservoir undergoing a thermal recovery process is typically idealized as a two-zone composite reservoir, in which, the inner region represents the swept region surrounding the injection well and the outer region represents the larger portion of the reservoir. Additionally, there is a great contrast between the mobilities of the two zones and the storativity ratio being different to one.

In this work, the models and techniques developed and implemented by other authors have been enhanced. Therefore, the interpretations of the well tests can be done in an easier way, without using type-curve matching. A methodology which utilizes a pressure and pressure derivative plot is developed for reservoirs subjected to thermal recovery so that mobilities, storativity ratio, distance to the radial discontinuity or thermal front and the drainage area can be estimated. The precedence of the heat source (in-situ combustion or hot injected fluids) does not really matter for the application of this methodology; however, this was successfully verified by its application to synthetic and field examples of in-situ combustion. The point of comparison was the input data used for simulation for the synthetic case and the results from simulation matching and from previous studies for the field cases.
CFD Technique to calculate tube skin peak temperatures in refinery furnaces
Authors: Diaz Fabian A. , Castro Jesús A.
Published: January 2020

Tube skin peak temperature is one of the major parameters in furnaces operation since they determine the life of the tubes and the extent of an operation run. This parameter is very difficult to calculate appropriately in magnitude and location within the furnace and commercial furnace simulators usually fail in its calculation. Computational fluid dynamics (CFD) is the only technique that calculates peak skin temperatures with great precision and accuracy since radiation and convective heat fluxes can be calculated taking into account every singularity of the geometry of the furnace and the burners. In this work is developed a technique to calculate this parameter using CFD commercial code (Ansys Fluent) and an in-house furnace simulator (EcoFursim), results of the simulations are compared with data from different furnaces from Barrancabermeja refinery (Barrancabermeja, Colombia) and good agreement is observed. Refinery furnace is referred in this paper to fired heaters for non reacting heat up of hydrocarbons or petroleum crude.
Património musical na Catedral de Angra no século XVII: três livros de polifonia vocal sacra e o seu possível contexto
Authors: Henriques Luís
Published: January 2020

A Catedral de Angra foi, desde a sua fundação em 1534, um importante centro musical na ilha Terceira e no arquipélago dos Açores. Embora a sua atividade musical não seja conhecida em detalhe, várias referências documentais sugerem que esta seria pelo menos próxima das catedrais do continente português. Um dos testemunhos documentais é a existência na Catedral de três livros de coro impressos de polifonia vocal sacra de dois dos mais conhecidos compositores portugueses da primeira metade do século XVII: Duarte Lobo e Fr. Manuel Cardoso. O período em que estes livros foram impressos (1605, 1613 e 1621) foi marcado por agitação na cidade de Angra durante a ocupação espanhola. Simultaneamente, a construção da nova Catedral durou quase um século, perturbando a sua atividade litúrgico-musical regular. Partindo dos três livros de polifonia existentes, o presente estudo analisa o património musical da Catedral durante a primeira metade do século XVII e a sua ralação com o seu contexto circundante.
A inovação arquitetónica nos Ateliers de Lisboa e Oeiras, entre 1867 a 1912
Authors: Fevereiro António
Published: January 2020

No final do século XIX e início do XX foram construídos em Lisboa e Oeiras ateliers para trabalho, mas também para exposição e convívio. Estes foram construídos de acordo com novos conceitos espaciais apoiados no desenvolvimento das técnicas construtivas, realçados pelo controlo da luz natural. Inicialmente o ecletismo definiu arquitetonicamente estes espaços, contudo à medida que o século chegou ao fim, os projectistas portugueses conciliaram de forma inovadora referências da sua cultura com as novas correntes estéticas internacionais. Estes ateliers enriquecem a arquitetura portuguesa deste período, além de trazerem novas reflexões em torno de quem lá trabalhou.

Professionalism, Variety and Knowledge Production in the Social Economy
Authors: Hall Peter
Published: January 2020

This keynote address explores the interplay between three forces that will shape the next few years of social economy practice and research. The first is variety, both with respect to existing and emergent social need, and with respect to the multiplicity of organizational forms adopted by social economy actors. The second concerns the forms of knowledge, ranging from instrumental knowledge to reflection and critique, which inform practices in the sector. Knowledge production is itself both enabled and constrained by the third force, professionalism, or the ways we structure the socialization and employment of those working in the sector. With variation an inherent characteristic of the social economy and with the ongoing search for appropriate models of professionalism, our collective knowledge production tasks remain unfinished.Ce discours principal explore les interactions entre trois forces qui vont façonner la pratique et la recherche en économie sociale au cours des prochaines années. La première est la variété, tant par rapport aux besoins sociaux actuels et naissants qu’à la multiplicité de formes organisationnelles adoptées par les acteurs de l’économie sociale. La seconde concerne les types de savoir informant les pratiques dans le secteur, du savoir instrumental jusqu’à la réflexion et la critique. La troisième force, le professionnalisme ou la manière dont on organise le recrutement et la socialisation de ceux et celles qui oeuvrent dans le secteur, permet la production du savoir tout en y imposant certaines contraintes. La variation étant une caractéristique intrinsèque de l’économie sociale, et la quête de modèles de professionnalisme appropriés se perpétuant, il est clair que nos tâches collectives de production du savoir demeurent inachevées.

Hubungan Gaya Kepemimpinan Ketua dan Efektivitas Kelompok Wanita Tani TOGA
Authors: Syahroni Iqbal , Amanah Siti
Published: January 2020

Leadership in a group can be seen through its effectiveness in group productivity, and goal attainment rate. Leadership style is a factor that influencing group effectivity. there are four leadership style: directive, supportive, participative, and achievement-oriented. Group effectivity is parted into productivity rate and goal attainment rate. The research objective was to analyze the correlation between leadership style and group effectivity. A census was conducted at Benteng Village involving two KWTs, namely KWT Benteng  Sejahtera (14 members) and KWT Puring (17 members). Data were collected through questionnaires, direct observation, and in-depth interviews. Data were analyzed using Rank Spearman correlation. Research’s results showed that the leadership style of KWT Puring and KWT Benteng Sejahtera are not dominated by just one style, the KWT leaders are showing the effectiveness in a situational condition. KWT Puring and KWT Benteng Sejahtera’s Participative leadership style are correlated with productivity rate, while KWT Benteng Sejahtera’s achievement-oriented leadership style is correlated with goal attainment rate.Keywords: goal attainment rate, leadership style, productivity rate, women farmer groups ABSTRAK Kepemimpinan dalam kelompok berpengaruh terhadap perkembangan anggota dan pencapaian tujuan kelompok. Gaya kepemimpinan ketua merupakan faktor yang mempengaruhi efektivitas kelompok, termasuk kelompok wanita tani (KWT). Terdapat empat gaya kepemimpinan: direktif, suportif, partisipatif, dan achievement-oriented. Efektivitas kelompok dapat dilihat dari tingkat partisipasi anggota dan tingkat pencapaian  tujuan kelompok. Tujuan penelitan ini adalah menganalisis hubungan antara gaya kepemimpinan dan efektivitas kelompok. Penelitian ini dilaksanakan di Desa Benteng, Ciampea, Kabupaten Bogor, dengan kasus KWT Benteng Sejahtera (14 anggota) dan KWT Puring (17 anggota). Data diperoleh secara sensus, didukung wawancara mendalam dan pengamatan langsung di lapangan. Data diolah menggunakan Rank Spearman untuk melihat hubungan antara gaya kepemimpinan, dukungan eksternal, kedinamisan kelompok dan efektivitas kelompok.
