Investigation of PH effect in a mixture of basalt and iron on co2 sequestration in synthetic brines
Authors: Ajayi Toluwaleke
Published: September 2019

CO2 sequestration in deep saline aquifers is a critical component of long-term storage options. It is suggested that the precipitation of mineral carbonates is mostly dependent on brine pH and is favoured above a basic pH of 9.0. However, brine pH will drop to acidic values once CO2 is injected into the brine. Therefore, there is a need to raise brine pH and maintain it stable. Synthetic brines were used here instead of natural brines because of the difficulty in obtaining and storing natural brines. Therefore, experiments were conducted to prepare a series of synthetic brines and to compare their suitability to natural brines for carbon sequestration. A typical formation rock (basalt) and a buffer solution (0.3M Tris buffer solution) were selected to buffer brine pH. The results show that synthetic brines prepared can be used as analogues to natural brines for carbon sequestration studies in terms of chemical composition and pH response. This study investigates the effect of iron ( ) in the pH of six synthetic brines prepared as analogue to oil-field brine by conducting a pH stability studies for CO2-brine experiment and CO2-basalt-brine experiment. In a subsequent step, studies were conducted to correlate how brine samples respond in the presence of basalt and the buffer solution. X-Ray powder Diffraction (XRD) analyses were also carried out to characterise the mineralogy of the synthetic brines. The result of the XRD confirmed that calcite was the major component that was dominated in the -brine–experiment while slight occurrence of calcite, iron oxyhydroxides and dolomite precipitated in the -rock-brine experiment. It was observed that ferric iron  and its reaction with host rock (basalt) did not contribute to pH instability therefore making it suitable for precipitation of carbonate mineral while ferrous iron in the absence of host rock did not contribute to pH instability therefore making it also suitable for precipitation of carbonate mineral.
Treynor Ratio to Measure Islamic Stock Performance in Indonesia
Authors: Qudratullah Mohammad Farhan
Published: September 2019

Treynor Ratio merupakan model pioner inovatif ukuran kinerja saham yang dikemukakan Jack Treynor pada tahun 1965 yang terdiri atas 3 (tiga) komponen, yaitu return saham, return bebas risiko, dan beta saham. Banyak penelitian mendekati return bebas risiko dengan suku bunga termasuk saat mengukur kinerja saham syariah, sedangkan suku bunga dilarang dalam konsep keuangan islam. Tulisan ini membahas variabel alternatif untuk mendekati return bebas risiko selain dengan suku bunga (BI-Rate), yaitu dengan 4 (empat) pendekatan, yaitu: menghilangkan suku bunga, mengganti dengan zakat rate, mengganti dengan inflasi, dan mengganti dengan gross domestic produc (GDP) pada model Treynor Ratio yang diimplementasikan pada pasar modal syariah di Indonesia periode Januari 2011-Juli 2018. Hasil yang diperoleh adalah terdapat kesesuaian yang sangat tinggi hasil pengukuran model Treynor Ratio dengan suku bunga dengan keempat model lainnya. Namun, model-model tersebut tidak menjamin bahwa saham yang memilki kinerja terbaik pada saat ini akan memilki kinerja terbaik dimasa yang akan datang atau sebaliknya. Dilihat dari kedekatan hasil pengukuran kinerjanya, kelima model Treynor Ratio tersebut dapat dikelompokan jadi 2 (dua), yaitu model dengan suku bunga, model dengan inflasi, dan model dengan GDP sebagai kelompok pertama, sedangkan model tanpa suku bunga dan model dengan zakat-rate sebagai kelompok kedua.

[Treynor Ratio is an innovative pioneer model the size of stock performance proposed by Jack Treynor in 1965 which consists of 3 (three) components, namely stock returns, risk free returns, and stock beta. Many studies approach risk-free returns with interest rates, including when measuring the performance of Islamic stocks, while interest rates are prohibited in the concept of Islamic finance. This paper discusses alternative variables to approach risk-free returns other than interest rates (BI-Rate), namely with 4 (four) approaches, namely: eliminating interest rates, changing zakat rates, changing inflation, and substituting gross domestic products (GDP) in the Treynor Ratio model that is implemented in the Islamic capital market in Indonesia for the period January 2011 - July 2018. The results obtained are very high conformity in the measurement results of the Treynor Ratio model with interest rates with the other four models. However, these models do not guarantee that stocks that have the best performance at this time will have the best performance in the future or vice versa. Judging from the closeness of the results of performance measurement, the five Treynor Ratio models can be grouped into 2 (two), namely models with interest rates, models with inflation, and models with GDP as the first group, while models without interest rates and models with zakat-rate as second group.]

Published: September 2019

Nereis sp. is an invertebrate member of Familia Nereidae, Classis Polychaeta that lives in the estuarin ecosystem as benthic. Nereis sp. is one of the natural foods that can trigger the maturation of shrimp gamete cells up to 70% because they contain high levels of amino acids and unsaturated fatty acids, but the fulfillment of Nereis sp. still rely from nature. That condition encourages the cultivation of Nereis sp., but there is not much information about it. This study aims to determine the metabolic rate and nutritional content of Nereis sp. with different maintenance salinity and feed.  This reasearch used immature Nereis sp with two different type of feed, i.e. with vegetable protein and animal protein. They were maintained in three different salinity i.e. 5, 15, and 25 ppt. The results showed that oxygen consumption rate of Nereis sp was affected by salinity of the medium, but was not influenced by the type of feed given. The highest oxygen consumption was observed in Nereis sp. that maintained at 25 ppt. The body protein content is influenced by the salinity and the type of feed given, while the fat content is not affected by the salinity and the feed. The highest protein, fat and carbohydrate content of the body was detected in salinity of 15 ppt and fed with vegetable protein foods.

Deduktive Schlüsse in der literaturwissenschaftlichen Praxis
Authors: Descher Stefan
Published: September 2019

It is sometimes suggested that deductive reasoning has no place in literary studies, particularly when it comes to the justification of literary interpretations. The thesis is that deductive arguments (almost) never occur and deductive reasoning plays no or at most a marginal role in the actual practice of interpretation. In this essay I will argue that this thesis is false. Using counterexamples, it can be shown that deductive arguments are de facto used in the practice of literary interpretation. Although only an exemplary and not comprehensive investigation of argumentative practices in literary studies can be made here, it can also be made plausible that deductive arguments are not exceptions, but a normal, regularly encountered and legitimate phenomenon of this practice. Furthermore, it can be shown that the thesis criticized here is based on a too narrow understanding of deductive reasoning. Finally, I will argue that (from a methodological point of view) it would be an unnecessary restriction to exclude deductions from our methodological toolbox: to abandon deductive reasoning from the practice of interpretation would be tantamount to renouncing a useful method of justifying (and refuting) interpretive hypotheses. Therefore, a fundamental methodological scepticism about deductive reasoning is unfounded.

The essay is structured as follows: First, I will present a current example of how the sceptical attitude towards deductions in literary studies is motivated (Section 1). I will show that the concept of deduction underlying this scepticism is usually based on the assumption that deductive arguments contain ›general rules‹ or ›law-like assertions‹ in their premises. Second, I will confront the concept of deduction assumed there with the understanding of deductive arguments as it is usually assumed in logic (Section 2). It will become apparent that a conception of deductive arguments based on general rules or law-like assertions is (though not false) too narrow. After a short caveat concerning the reconstruction of ›real‹ arguments in general (Section 3), I will present some examples of deductive arguments in interpretations of literary texts (Section 4). These arguments have the logical form of arguments from modus ponens, modus tollens and disjunctive syllogism. The examples not only show that deductive reasoning actually occurs in the practice of literary interpretation, but also make it plausible that deductive arguments are an unproblematic and legitimate method of justifying and/or refuting interpretations. After considering what causes may have led to the dissemination of the thesis that deductions do not occur in practice (Section 5), I conclude with a plea to accept deductive arguments as a legitimate tool of justification among many others (Section 6).

Published: September 2019

La reciente ocurrencia de infecciones por el virus vaccinia en animales y humanos en distintos lugares de la geografía colombiana, sumadas a otras por éste y por otros virus pertenecientes al género Orthopoxvirus (familia Poxviridae), ocurridas en algunos países de Suramérica, África, Asia y Europa se convierten en evidencia de la inminente emergencia y re-emergencia de este género, con características biológicas y epidemiológicas que le confieren gran interés para la salud pública del mundo, como lo fue en el pasado una de sus especies representativas: el virus de la viruela. Esta emergencia y re-emergencia parecen estar relacionadas con la suspensión en las décadas de los 70s y 80s de las campañas de vacunación contra la viruela, las cuales; insospechadamente estuvieron protegiendo a la población, no únicamente contra este virus, sino contra otros del mismo género. En el presente artículo se hace una revisión de la biología y epidemiología de los principales miembros del género Orthopoxvirus, su presentación clínica, antecedentes históricos, contexto social, e impacto en la salud pública mundial en el pasado, presente y a futuro.

Published: September 2019

Introducción. Los sistemas silvopastoriles se presentan como una alternativa para el uso sostenible de los recursos naturales, por ello, surge la necesidad de identificar especies potenciales para su establecimiento en el trópico de altura. Objetivo. El objetivo fue evaluar el crecimiento inicial de ocho especies leñosas en un diseño silvopastoril para protección de fuente hídrica. Materiales y métodos. El estudio se realizó en el centro de investigación Obonuco de la Corporación Colombiana de Investigación Agropecuaria (Pasto, Colombia) entre septiembre 2017 y junio 2018, se desarrolló un diseño de bloques al azar en arreglo factorial, donde interactuaron especies arbóreas/arbustivas diferenciadas por su hábito de crecimiento (estrato alto: Cedrela montana, Quercus humboldtii, Ficus andicola; estrato medio: Salix babylonica, Alnus acuminata, Smallanthus pyramidalis; estrato bajo: Morella pubescens y Sambucus nigra) y altitud (2750, 2770 y 2800), con cuatro repeticiones para evaluar variables morfométricas y calidad de plántulas. Resultados. En la variable altura, el mejor comportamiento se presentó en Ficus andicola a 2750 msnm con 191,37 cm y Alnus acuminata a 2800 msnm con 181,83 cm. En diámetro de tallo sobresalieron Ficus andicola a 2750 msnm con 42,98 mm, Smallanthus pyramidalis a 2800 msnm con 37,24 mm y Sambucus nigra a 2800 msnm con 8,16 mm. El número de rebrotes no evidenció efecto significativo de la interacción y, en calidad de plántulas, Quercus humboldtii a 2750 y 2700 msnm y Ficus andicola a 2750 msnm, presentaron la mejor calidad de individuos; mientras que, Cedrela montana mostró mortalidad en las tres altitudes evaluadas. Conclusiones. Las especies nativas sobresalieron por su capacidad de adaptación, reflejada en un rápido y óptimo crecimiento y desarrollo; lo cual evidencia su gran potencial para ser evaluadas en sistemas silvopastoriles de manera asociada, para determinar sus beneficios y potencial contribución con el desarrollo sostenible de la ganadería en la región.

Authors: Mojica-Rodríguez Edwin , Castro-Rincón Edwin , Carulla-Fornaguera Juan Evangelista , Lascano-Aguilar Carlos Eduardo
Published: September 2019

Introducción. Se ha sugerido que el perfil lipídico en la leche bovina afecta la salud humana y se ha identificado que el ácido linoleico conjugado (ALC c9 t11) podría tener efectos anticarcinogénicos. En trópico alto se ha investigado el efecto de la alimentación sobre el perfil lipídico de la leche, pero pocos estudios se han hecho en trópico bajo. Objetivo. El objetivo fue evaluar el efecto de tres intensidades de pastoreo (1, 2 y 3 animales ha-1) en pasto Guinea cv. Tanzania (Megathyrsus maximus) sobre la producción, composición y perfil lipídico en la leche de vacas mestizas en diferentes tercios de lactancia. Materiales y métodos. De septiembre a octubre de 2013, se seleccionaron dos grupos de nueve animales (tres vacas en cada tercio de lactancia) y se asignó una vaca por tercio de lactancia a cada intensidad de pastoreo (tratamiento), durante 42 días de evaluación, en un diseño de cuadrado latino 3 x 3 replicado. Resultados. La producción de leche fue similar (p>0,05) entre tratamientos y fue mayor (p<0,05) en vacas en inicio de lactancia. Los tratamientos no afectaron (p>0,05) la composición de la leche, pero el tercio de lactancia tendió (p<0,10) a incrementar la concentración de sólidos totales y grasa. La grasa de la leche bovina en el pasto manejado con intensidad de pastoreo de 2,0 y 3,0 animales ha-1 tuvo una concentración mayor (p<0,05) de ALC c9 t11 y de ácidos grasos poliinsaturados (AGPI), que cuando el pasto fue manejado con 1,0 animal ha-1. El tercio de lactancia no afectó (p>0,05) la concentración de ALC y AGPI. Conclusión. El manejo del cultivar Tanzania con intensidades de pastoreo de 2,0 y 3,0 animales ha-1, resultó en las concentraciones más altas de ALC (c9 t11) y AGPI en la grasa de la leche, lo cual podría tener efectos positivos en salud humana.
Remoción mecánica del material senescente para la recuperación de pasturas
Authors: Villalobos-Villalobos Luis A. , WingChing-Jones Rodolfo
Published: September 2019

Introducción. La acumulación de material senescente en pasturas tropicales es resultado de la alta producción de biomasa y bajo nivel de aprovechamiento en pastoreo. La remoción de senescencia en pasturas permite que el ganado acceda a estratos bajos durante el pastoreo, lo que genera un rebrote con mayor concentración de nutrientes. Objetivo. El objetivo de este estudio fue evaluar la respuesta de los pastos Estrella africana (Cynodon nlemfuensis Vanderyst.) y Mombasa (Megathyrsus maximus Jacq.) a la remoción de material senescente, con base en sus componentes estructurales, biomasa y contenido de nutrientes. Materiales y métodos. El experimento se llevó a cabo entre abril y agosto de 2017 en dos fincas, una ubicada en Turrialba, Cartago y la otra en San Carlos, Alajuela. Se utilizó un diseño de chi-cuadrado para evaluar la remoción de material senescente versus los respectivos controles. Resultados. La remoción de pasto senescente incrementó la proporción de hoja en ambos pastos. La biomasa producida tuvo un contenido proteico mayor y menos pared celular, siendo a su vez más digestible que el control sin remoción. Los cambios estructurales tuvieron una mayor duración en el pasto Mombasa, lo cual se atribuyó a las diferencias en arquitectura de la planta respecto al pasto estrella. Conclusión. La remoción del pasto senescente es una estrategia para modificar la composición estructural de las pasturas, con lo que se mejora el perfil nutricional de la materia seca producida. El sistema e intensidad de pastoreo pueden contribuir a una menor acumulación de senescencia, y producir un forraje de mayor valor nutricional por un plazo mayor.

Published: September 2019

El presente capítulo los autores discernimos sobre la intricada relación en la que se desenvuelven las empresas cooperativas mexicanas, en el ámbito del turismo de naturaleza, en sus modalidades: ecoturismo, rural y de aventura. Entre las principales dificultades a las que se enfrentan, se puede mencionar el contexto y modelo económico en el cual se desenvuelven, (sistema que privilegia el libre mercado, la competencia, y el sostén a la empresa privada). Si bien es cierto que hay políticas y leyes que disponen apoyo al cooperativismo, estas empresas se han considerado como formas de asistencia a las comunidades rurales y grupos vulnerables. Dicha situación les permite participar dentro de esta modalidad para obtener fondos para realizar sus emprendimientos, sin embargo, se ha detectado que debido a la falta de experiencia de los socios; tanto en el cooperativismo, la gestión de la empresa y el establecimiento de relaciones con otros sectores; muchas de ellas colapsan ante las circunstancias y dinámicas de la sociedad. El objetivo del trabajo aquí plasmado es teorizar precisamente, cómo se entrelazan los factores del sistema social, turístico, económico para favorecer el desarrollo turístico sustentable a la luz del enfoque sistémico.

Se cuestionan también algunos mitos entre educación y globalización y se identifican algunos de los efectos negativos de las deficiencias del sistema educativo nacional y su impacto en la vida económica, social y política contemporánea.
UNA MIRADA AL RELATO DE LA HUMANIDAD Y EL PANORAMA DEL DESARROLLO SUSTENTABLE EN LOS ALBORES DEL TERCER MILENIO
Authors: Covarrubias - Tovar Natividad
Published: September 2019

El abordaje multidimensional del medio ambiente desde las diferentes ciencias o disciplinas ha generado en los distintos escenarios o sedes, un sinnúmero de reflexiones y debates registrados en un universo de documentos, como fieles testimonio de las conceptualizaciones y el cambio de percepción del ambiente, aunado a ello la reorientación de los modelos de desarrollo han forjado un cambio de paradigma, en el que los involucrados: individuos, empresas, organizaciones y gobiernos, deben asumir nuevos compromisos bajo la actuación consciente y de mejora continua, donde la trasparencia, equidad, ética, eficiencia, responsabilidad, pero sobre todo la voluntad, constituyen el motor de un nuevo

desarrollo. Como respuesta a este nuevo enfoque en materia de la administración del medio ambiente emergieron nuevas instituciones y organismos en busca de dar respuesta a la problemática del deterioro ambiental, desafortunadamente el esfuerzo ha sido entorpecido por la falta de continuidad de los programas de protección y conservación, manifestados principalmente en un desgaste de recursos económico, humano y hasta ecológico reflejados en el desarrollo pasivo del país y sus actividades productivas.

Hasta hace relativamente poco tiempo se asumía que el papel del desarrollo era solo generar capital, visión que actualmente no es suficiente ni aceptable, el desarrollo ahora implica la consideración de dimensiones básicas: económica, social y ambiental y las complementarias como la tecnología y la política. Se requiere, además, de cambios no solo en los procesos productivos, sino en los hábitos de consumo y en consecuencia en la oferta de nuevos productos y la modificación de sistema de gestión y políticas, que no solo mitiguen el deterioro ambiental, sino que prevengan y lo minimicen.

Published: September 2019

El desarrollo como fenómeno complejo presenta contradicciones naturales entre sus múltiples dimensiones, mostrando  conflictos que lo llevan al plano de lo político, donde por consecuencia; el ejercicio de la política deviene como un elemento fundamental en su promoción y gestión.

En este contexto, emergen las políticas públicas donde el papel del Estado como actor definitivo en la gestión del desarrollo de la sociedad queda de manifiesto, estableciendo pautas que resultan trascendentes o irrelevantes en función de los resultados obtenidos a partir de la instrumentación de las mismas.

En México, se ha diseñado e instrumentado  la política de desarrollo atendiendo el contexto nacional e internacional en diferentes momentos históricos, originando el planteamiento de reformas estructurales que al aplicarse han influido determinantemente en  las condiciones que vive actualmente la sociedad mexicana, donde las disparidades  y  desequilibrios son evidentes.

La inserción de México al proceso de globalización como etapa de desarrollo del capitalismo, ha sido el origen de las reformas estructurales de primera generación en la era moderna del país, en las cuales al igual que en las reformas subsiguientes,   uno de los objetivos primordiales en su diseño e instrumentación ha sido la estabilidad y el crecimiento económico. Hoy en día,  se han plateado las reformas estructurales consideradas como de tercera generación que entre otros objetivos, vuelven a retomar el crecimiento económico como prioridad.

En un análisis prospectivo se presenta un primer acercamiento respecto de los posibles efectos en el crecimiento económico y el desarrollo de la sociedad mexicana, de las reformas estructurales propuestas en 2014 por el gobierno federal, buscando vincular las repercusiones en el turismo que de igual forma, se estima prioritario en la política sectorial. Para realizar este análisis se lleva a  cabo un breve recuento de los efectos de las reformas estructurales de primera y segunda generación como experiencia y antecedente a lo actual.

The article mentions the results of the new analysis of gas-geochemical and high resolution shallow seismic data acquired by the sea surveys in 2016, which revealed a remarkable coincidence between the seabed gas anomalies at river mouth area of Gulf of Tonkin and the gas distortion/accumulation phenomena in the near-surface sediment layers, especially right above the large tectonic fault systems, such as Red river, Lo river and Chay river. The gas-geochemical analysis reveals the existences of thermogenic and metamorphic methane and carbon dioxide gases within the faults of Red river and on Cat Ba island, anomalies of helium and hydrogen as well as the “heavy” isotopic carbon signals of methane and carbon dioxide in the areas of near-surface active faults. These new results suggest the initial conclusions about the relationship between gas-geochemical field and tectonic fault activities in study area.

Authors: Cuong Le Duc , Thao Nguyen Van
Published: September 2019

Delft3D model employed to simulate the distribution and transport of suspended sediment and black carbon in Ha Long bay shows outcomes meeting with results from previous experiment studies. In the rainy season, suspended matter in surface layer is mainly in waters of western and southwestern Cat Ba island regions, and from Cua Luc toward the south nearshore areas with concentration of 50–130 g/m3. The concentration of suspended setdiment in the waters from Cua Luc to the north nearshore area is from 20 g/m3 to 50 g/m3 and that of offshore areas is 2–20 g/m3. In the dry season, the average concentrations of suspended matter are lower, approximately 110–150 g/m3 compared to the rainy season. In the rainy season, the total particulate carbon in surface layer is 0.0016–0.0028 kg/m3 and in the dry season, it ranges from 0.0001–0.005 kg/m3.
Why from Didactics the teacher’s education is not favored?
Authors: Gascón Agustin de La Herrán , Fortunato Ivan
Published: September 2019

Abstract This essay could also have been titled: “What if teacher training was radically disoriented?” It is part of other broader question: “What if our education and Pedagogy were radically wrong?”. In its content, the authors’ arguments are presented with the aim of expressing possible insufficiencies of teacher training and, therefore, of Didactics, as a science of formation by antonomasia. It is presented the possibility that it prevailed in education and training a general bias towards the outside and consequently a deficit of radical attention, and it is an imperative refocusing completely the teacher training. In the following lines they are condensed over two decades of observations in this regard. From a methodological perspective it will proceed with a dialectical and hermeneutical orientation supported by the “radical and inclusive training approach”, from which critical arguments with a constructive purpose will be offered. After responding to the target, the work offers an alternative model of training, bringing in new development to pedagogical knowledge in a relevant subject for researchers and teaching professionals.

Uma “catástrofe do tempo”: narrativa e historicidade pelas Vozes de Tchernóbil
Authors: Manna Nuno , Lage Igor
Published: September 2019

Resumo Este artigo propõe uma análise das experiências do tempo registradas no livro Vozes de Tchernóbil, de Svetlana Aleksiévitch. A partir da expressão “catástrofe do tempo”, que a própria autora utiliza para referir-se ao desastre nuclear, buscamos entender de que maneiras as narrativas presentes na obra tentam lidar com a potência desse acontecimento-limite, que rompe com os parâmetros de compreensão temporal antes estabelecidos. Na leitura crítica dos esforços de comunicação das testemunhas ouvidas e nos excertos autorreferentes de Aleksiévitch, propomos uma reflexão sobre as historicidades possíveis diante da incompreensibilidade da catástrofe, por meio da narrativa e do cotidiano.
A tradição como problema nos estudos de comunicação: reflexões a partir de Williams e Ricoeur
Authors: Leal Bruno Souza , Sacramento Igor
Published: September 2019

Resumo Neste artigo, buscamos refletir sobre a tradição como um problema a ser enfrentado nos estudos em Comunicação. A partir da retomada de dois importantes pensamentos sobre o tema, nas obras de Raymond Williams e de Paul Ricoeur, explicitamos a dimensão interpretativa e os complexos movimentos temporais presentes na tradição. A retomada desses autores, de filiações e preocupações teóricas bem diversas, não visa buscar conexões entre eles, mas mostrar como ambos, a seu modo, entendem a tradição como algo instável, imersa em conflitos epistêmicos, éticos e ideológicos e encontram, na disputa sobre o passado, a configuração do presente e a projeção de futuros.
Effect of orthodontic treatment on alveolar bone thickness in adults: a systematic review
Authors: Sendyk Michelle , Linhares Daniele Sigal , Pannuti Claudio Mendes , Paiva João Batista de , Rino Neto José
Published: September 2019

ABSTRACT Objectives: This review aimed at evaluating changes in alveolar bone thickness after completion of orthodontic treatment. Methods: Only prospective clinical studies that reported bone thickness in adult patients undergoing non-surgical orthodontic treatment were considered eligible. MEDLINE, EMBASE and LILACS databases were searched for articles published up to July 2018. Results: A total of 12 studies met the selected criteria. Most of the studies showed that orthodontic treatment produces a reduction in bone thickness of incisors, mainly at the palatal side. Conclusion: On patients undergoing different orthodontic treatment techniques, there was a significant bone thickness reduction, mainly on the palatal side. Clinical relevance: These findings are relevant and have to be considered in diagnosis and planning of tooth movement, in order to prevent the occurrence of dehiscence and fenestration in alveolar bone.

Published: September 2019

ABSTRACT Introduction: Conventional direct and indirect bonding techniques fail to obtain the ideal bracket position. Objective: To compare the accuracy of virtual and conventional direct bonding of orthodontic accessories. Methods: A single virtual configuration (dental mannequin with Class I malocclusion) served as basis for generating the reference model (treated virtually) and the intervention models (10 digital models and 10 solid models, obtained by means of prototyping). A total of 560 teeth were then equally distributed between a group of orthodontists (Group I, direct bonding; and Group II, virtual bonding), working in two different time intervals. The individual positions of the accessories were measured after three-dimensional superimposition with customized software. The Student’s-t test for paired samples, and Chi-square tests were used for statistical analysis, both at the level of significance of 5%. Results: In comparison of the errors in raw values, there were significant differences only in the vertical (p< 0.001) and horizontal dimensions (p< 0.001). Considering the groups of ranges by clinical limits of the deviations, these differences were significant in the three dimensions, vertical (p< 0.001), horizontal (p= 0.044) and angular (p= 0.044). Conclusion: Virtual bonding made it possible to obtain more precise/accurate positioning of the orthodontic accessories. The potential accuracy of this method brings new perspectives to refining the indirect bonding protocols.
Biomechanics of extra-alveolar mini-implants
Authors: Almeida Marcio R.
Published: September 2019

ABSTRACT It is undeniable that extra-alveolar mini-implants anchorage has revolutionized Orthodontics. Correspondingly, the proper understanding of mini-implants biomechanics allowed to broaden the range of dental movements as never seen before in clinical practice. However, in order to produce better treatments, especially regarding the effects in occlusal plane, it is important to be aware of the numerous possibilities of applying force systems based on skeletal anchorage. Thus, this paper aims to address, by means of clinical cases, the application of biomechanics concepts that are extremely relevant to the proper employment of extra-alveolar mini-implants.

Abstract Objective: To describe the therapeutic itinerary of people with tuberculosis in face of their health needs. Method: Descriptive, qualitative study. Semi-structured interviews were carried out with ten patients. Hermeneutic-dialectic method of analysis and concept of therapeutic itinerary as driver of the analysis. Results: Most had classic symptoms at the beginning, however there was a case with coughing for more than one year. Entrance door, access to diagnosis and treatment were predominant in Primary Care, through smear microscopy and X-ray; patients had to pay for exams. Decentralization of treatment for other services when necessary or by link with the professional. The patient followed the decisions of the professionals and the support of relatives; prejudice regarding the disease was noted. Conclusions and implications for practice: Fragility in disease management, importance of bonding and family. It should be considered the impact of the disease and the need to support patients to ensure continuity of care.

Resumo Abordaremos neste texto as relações entre o programa de pesquisa em sociologia da arte liderado por Roger Bastide na Faculdade de Filosofia, Ciências e Letras da Universidade de São Paulo (FFCL-USP), nas décadas de 1940 e 1950, e a tese incompleta de Antonio Candido sobre o cururu. A análise desse material e de seu contexto permite avaliar conexões teóricas e metodológicas entre os autores e flagrar as possíveis disputas em jogo nesse momento em torno da sucessão do sociólogo francês na USP por seus discípulos e discípulas paulistas.
DOIS PAÍSES, O MESMO DILEMA? REFLEXÕES SOBRE A DEMOCRACIA E O RACISMO NOS ESTADOS UNIDOS E NO BRASIL
Authors: MESQUITA GUSTAVO
Published: September 2019

resumo Roger Bastide e Florestan Fernandes atuavam em pesquisas sobre relações raciais financiadas por organizações internacionais quando, na década de 1960, os Estados Unidos criaram ações afirmativas para responder à desigualdade racial. As conclusões dos sociólogos estimularam discussões acerca do mesmo problema no Brasil. Entendeu-se naquela época que também temos um dilema, ou seja, uma democracia fracionada, excludente da população negra. Discuto neste artigo a formação do pensamento sociológico de Bastide e Fernandes à luz de teses norte-americanas de relações raciais, assim como o impacto desse pensamento no debate sobre racismo brasileiro.
HISTORY OF THE “HUMAN SCIENCES” AND WALLACE’S SCIENTIFIC VOYAGE IN THE AMAZON: NOTES ON HISTORIOGRAPHICAL ABSENCES
Authors: SILVA VICTOR RAFAEL LIMEIRA DA
Published: September 2019

Abstract This essay analyses a particular historiographical bibliography with the aim of addressing the divergence between history and history of science. I argue that the absence of the history of the human sciences in the historiography of science expands the distance between the history of science and other disciplines of historical studies. To ponder this hypothesis, I will analyse the historiography of Alfred Russel Wallace’s scientific voyage in the Amazon (1848-1852), arguing that the omission of the ethnographic dimension of this expedition exposes important aspects to understand the nature of such dissension and its effects on the construction of the history of the human sciences.
HERS: Modeling Influential Contexts with Heterogeneous Relations for Sparse and Cold-Start Recommendation

Published: September 2019

Classic recommender systems face challenges in addressing the data sparsity and cold-start problems with only modeling the user-item relation. An essential direction is to incorporate and understand the additional heterogeneous relations, e.g., user-user and item-item relations, since each user-item interaction is often influenced by other users and items, which form the user’s/item’s influential contexts. This induces important yet challenging issues, including modeling heterogeneous relations, interactions, and the strength of the influence from users/items in the influential contexts. To this end, we design Influential-Context Aggregation Units (ICAU) to aggregate the user-user/item-item relations within a given context as the influential context embeddings. Accordingly, we propose a Heterogeneous relations-Embedded Recommender System (HERS) based on ICAUs to model and interpret the underlying motivation of user-item interactions by considering user-user and item-item influences. The experiments on two real-world datasets show the highly improved recommendation quality made by HERS and its superiority in handling the cold-start problem. In addition, we demonstrate the interpretability of modeling influential contexts in explaining the recommendation results.
