Published: September 2019

A contracted RF (40.68 MHz) arc discharge of atmospheric pressure, stabilized between two rod electrodes, was used to obtain trichlorosilane by the reaction of hydrogen reduction of silicon tetrachloride (SiCl4). In model mixtures of macro-composition in the ratio H2/SiCl4/CCl4=10/1/1, it was shown that C and SiC are the main solid-phase product which are deposited on the surface of electrodes in the form of dendrides. The temperature of the ends of the electrodes determined using emission thermometry is 1600 K. The thermodynamic analysis of H2+SiCl4+CCl4 system confirms that the formation of C and SiC occurs in the temperature range of 1600 K. The deposition of solid-phase products occurs on the electrodes in the zone of high electric field strength.

Published: September 2019

Gas mixtures containing fluoro-nitriles C4F7N or fluoro-ketones C5F10O as minority components (<20%) have been identified as promising alternatives to SF6 in medium voltage gas-insulated switchgear (GIS) applications, because of their low Global Warming Potential together with their dielectric strength values being comparable to SF6. The buffer gases in such fluoro-nitrile or fluoro-ketone based gas mixtures are usually N2, O2, CO2, or air. In this contribution, we provide calculation results of transport properties, assuming local thermodynamic equilibrium (LTE), of thermal plasma containing following gas mixtures: C4F7N-CO2 and C4F7N-CO2-O2. The modifications in the thermodynamic and transport properties upon the addition of oxygen to the C4F7N-CO2 mixtures in the temperature range 300 K-30 kK at 1 bar are provided and discussed. These properties have been utilized to calculate the plasma temperature profile for a free-burning arc in a companion paper.

Authors: Babou Y. , Corfdir P. , Suetterlin R.-P.
Published: September 2019

The study addresses the post arc ablation (PAA) of PTFE (Polytetrafluoroethylene) material after being stressed by high current arcs. Arcs were generated in ambient air applying AC or DC current profiles to reach energy input in the range 7-22 kJ. The characterization has been performed essentially based on standard optical measurement techniques. The shadowgraph technique enabled us to show that the PAA flow is composed by a significant amount of carbonaceous soots lasting for several dozens of milliseconds after current interruption. The pyrometry technique allowed to estimate the soots temperature in the range 1400-2200 K.

Authors: Liška Vladimír , Dostálek Miroslav
Published: September 2019

Purpose: To confirm the influence of multilevel metabolic disturbance of insulin dependent diabetes mellitus (IDDM) on the vision even before the onset of the other changes routinely evaluated by ophthalmologists. Methods: Contrast sensitivity functions (CSFs) were estimated using the VCTS 6500 board. The standardised measurement procedure was performed. The value of the threshold contrast sensitivity was obtained for five spatial frequencies (1.5 - 3 - 6 - 12 - 18 c/deg). Other data was collected (duration of diabetes, BCVA, funduscopy, fluoresceine angiography, HbA1C). The study group consisted of 48 IDDM patients (94 eyes) without diabetic retinopathy and with Snellen BCVA > 1.0. The control group (56 normals, 98 eyes) was age and BCVA matched. Results: Highly statistically significant decrease of the CSFs in all spatial frequencies in the study group was obtained. Correlation between duration of the diabetes and impaired degree of CSFs was present in the middle spatial frequency. No significant changes in CSFs were found among patients with pathological value of glycated hemoglobin HbA1c (>7.8 %). Conclusions: If compared with routinely used Snellen visual acuity, the CSFs are more complex descriptors of the subjects vision abilities. IDDM has an influence on these sensitive functions, especially during examination in the middle spatial frequency of 6 and 12 c/deg, before disturbing visual acuity and before changes in the retinal morphology. Decrease of CSFs was influenced mainly by the patients’ age and partially (in the middle spatial frequency) by the IDDM duration.

Published: September 2019

Liposomes are nanocapsules successfully applied in pharmacy and medicine. Their usage in the food industry could be increased by the development of alternative, cost-efficient lecithin materials. This work is a continuation of the previous two papers describing five different extractions of egg yolk lecithins and the preassessment of their usefulness for liposome formation. Physicochemical properties of extracts differed due to distinct composition. The aim of this research was to further characterise the extracts-based liposomes, especially in terms of nanomechanical properties and structural diversity. Five previously described extracts were used for liposomes preparation employing Bangham technique. Vesicles were analysed with the use of dynamic light scattering, flow cytometry, and atomic force microscopy. The results were tested for correlation with the composition of the extracts. It was proved that the chemical composition of the shell-forming material determined the size, structure, stability, and mechanical properties of the vesicles. The observed effects were found to result not only from differences in the content of major components, i.e. phospholipids, acylglycerols, and cholesterol, but also in the relative proportions. Minor constituents, i.e. tocopherols and carotenoids, were also found to be of significance. Strong correlations between size and Zeta potential of the vesicles with the content of carotenoids were determined.

The Gamification of Political Participation
Authors: Loh Wulf
Published: September 2019

Political participation lies at the heart of normative democratic theory. To foster participatory interactions between citizens, some advocates and designers are resorting to gamification as the use of psycho-motivational involvement strategies from games in non-game contexts. The hope is that through gamification mechanisms, citizens will be drawn more easily towards participation platforms, apps, and digital services, as well as remain there longer, thereby effectively enhancing participation numbers and time. In this article, I will explore the potential problems of these involvement strategies, namely the worry that they may be able to undermine citizen’s individual and political autonomy by manipulating them into participating. Depending on the severity of the psycho-motivational effect as well as the covertness of the mechanism, gamification may constitute inadmissible forms of paternalism.

Published: September 2019

Zahlreiche Fragestellungen bei Design, Errichtung und Betrieb von Windenergieanlagen erfordern Vibrationsmessungen, insbesondere auch an Rotorblättern unter Betriebsbedingungen. Verbaute Sensoren können diese Aufgabe nur punktuell, extern angebrachte nur mit großem Aufwand und eventueller Beeinflussung des Messobjektes erfüllen. Als anlagenunabhängiges, distantes Messverfahren soll hier eine Kombination aus Laser-Doppler-Vibrometer mit einem Trackingverfahren für die Verfolgung der Rotordrehung vorgestellt werden. Es erfordert eine Trennung der Effekte, die durch die makroskopische Bewegung des Rotors auftreten, von den zu messenden Vibrationsbewegungen. Neben dem Doppler-Effekt der schnellen Rotorbewegung werden dazu das Signalrauschen der zurückgestreuten kohärenten Laserstrahlung, sowie Bewegungsartefakte aufgrund des schrägen Blickwinkels erörtert. Erste Testmessungen konnten trotz dieser Herausforderungen die Anwendbarkeit der Methode demonstrieren.

Published: September 2019

The present study explores the effects of constant and space-dependent viscosity on Eyring–Powell fluid inside a circular pipe. The heat transfer analysis is also considered. Using the normalised quantities, the governing equations are transformed into dimensionless form, and then the solution of the constructed nonlinear differential equations is calculated. The perturbation method is used to find the analytical expressions of velocity and temperature profiles as a function of pipe radius. The perturbation solution is validated against explicit finite difference numerical method, and errors of each case are plotted. The accuracy in velocity and temperature of finite difference method relative to the perturbation method is of order 10−2 and 10−4, respectively, in both cases of constant and space-dependent viscosity. The effects of various emerging parameters, namely, modified rheological parameter

Authors: Faramarzi Masoumeh , Sadighi Mehrnoosh , Mirhashemi Sayeh
Published: September 2019

Background. The aim of the current study was to evaluate implant surface changes following radiation with diode laser beams at various energy levels. Methods. Twenty implants (Dentis, Korea) were irradiated with diode laser, and two implants were considered as controls. The samples were irradiated at energies of 1.5, 2.5, 3.5, 4.5, 5.5 W for 5 and 10 seconds. Then surface implant changes were evaluated using Scanning Electron Microscopy (SEM). Results. At irradiation with laser beam energies of 1.5, 2.5, 3.5 W, there were no significant morphologic changes and any melting on implants and the surfaces in SEM analyses were similar to the control group surfaces. However, irradiation with 4.5 and 5.5 W for 5 and 10 seconds resulted in surface changes. In particular, after irradiation with 5.5-W diode laser beams for 10 seconds, extensive melting was visible. Conclusion. The results of the current study showed that diode laser beams up to 3.5 W did not damage implant surfaces; therefore, they might be useful for treatment of peri-implantitis.

Published: September 2019

Boundaries in the Drosophila bithorax complex (BX-C) enable the regulatory domains that drive parasegment-specific expression of the three Hox genes to function autonomously. The four regulatory domains (iab-5, iab-6, iab-7, and iab-8) that control the expression of the Abdominal-B (Abd-B) gene are located downstream of the transcription unit, and are delimited by the Mcp, Fab-6, Fab-7, and Fab-8 boundaries. These boundaries function to block cross talk between neighboring regulatory domains. In addition, three of the boundaries (Fab-6, Fab-7, and Fab-8) must also have bypass activity so that regulatory domains distal to the boundaries can contact the Abd-B promoter. In the studies reported here, we have undertaken a functional dissection of the Fab-8 boundary using a boundary-replacement strategy. Our studies indicate that the Fab-8 boundary has two separable subelements. The distal subelement blocks cross talk, but cannot support bypass. The proximal subelement has only minimal blocking activity but is able to mediate bypass. A large multiprotein complex, the LBC (large boundary complex), binds to sequences in the proximal subelement and contributes to its bypass activity. The same LBC complex has been implicated in the bypass activity of the Fab-7 boundary.

FORMULAÇÃO ESPECULATIVA DO PENSAMENTO TRANSCENDENTAL: a dialética enquanto radicalização do pensamento transcendental
Authors: Oliveira Manfredo Araújo de
Published: September 2019

Klaus Hartmann interpreta a Dialética como uma radicalização do pensamento transcendental. A opção ontológica, tal como ela é feita pelo autor, significa que o método transcendental transborda, sai de seus limites clássicos, sai de si mesmo e se constitui como filosofia dialética. As categorias, ligadas umas às outras por relações de negação, só possuem fundamento e legitimação enquanto são mediadas por um grande "sujeito conclusivo", que é o próprio pensamento enquanto ideia absoluta.
A ONTOLOGIZAÇÃO DA LÓGICA EM HEGEL COMO CRITICA À CRITICA KANTIANA À ONTOLOGIA CLÁSSICA
Authors: Costa Regenaldo Rodrigues da
Published: September 2019

Durante aproximadamente vinte séculos o que se entendia predominantemente como ciência era a ontologia clássica (Metafísica clássica), entretanto, a partir da modernidade ela começou a perder o status de cientificidade e foi a filosofia crítica de Kant que de forma radical apontou para a sua impossibilidade enquanto ciência. Hegel, porém, acha que a ciência só é verdadeiramente efetiva enquanto ontologia, de modo que ele toma como tarefa de sua filosofia o resgate da ontologia enquanto ciência. Neste horizonte, Hegel através da ontologização da lógica se propõe a resgatar a ontologia enquanto ciência, porém esta é uma nova concepção de ontologia e se apresenta como crítica em relação à ontologia clássica e a crítica kantiana à ontologia clássica.

Building on a set of criteria used as a scientific basis for conservation zoning of natural marine resources is essential. In this study, we propose the set of criteria to select the suitable natural clam beds of Lutraria rhynchaena for protection priority from 16 sites in Cat Ba - Ha Long bay. Research results have built a set of 13 different criteria, including area, density, benthic substrate, food organisms, turbidity, water flow, water depth, predators, salinity, benthic organisms, pollution, area location and zoning conflicts. The criteria are divided into 5 groups, in which the area and density have the highest coefficent of 5, followed by the zoning conflict with the coefficient of 4, the pollution with the coefficient of 3, the efficient of benthic substrate and  water flow is 2, the remaining criteria have a same coefficient of 1. The highest points are evaluated at Tung Sau bed (station 12) with a score of 254 points, followed by Van Boi beach (station 7) with a score of 235 points, the bed is in Trinh Nu Cave (Station 13) with a score of 229 points, which are proposed to be prioritized sites for conservation.

Published: September 2019

ABSTRACT Alice in Wonderland syndrome (AIWS) is a paroxysmal, perceptual, visual and somesthetic disorder that can be found in patients with migraine, epilepsy, cerebrovascular disease or infections. The condition is relatively rare and unique in its hallucinatory characteristics. Objective: To discuss the potential pathways involved in AIWS. Interest in this subject arose from a patient seen at our service, in which dysmetropsia of body image was reported by the patient, when she saw it in her son. Methods: We reviewed and discussed the medical literature on reported patients with AIWS, possible anatomical pathways involved and functional imaging studies. Results: A complex neural network including the right temporoparietal junction, secondary somatosensory cortex, premotor cortex, right posterior insula, and primary and extrastriate visual cortical regions seem to be involved in AIWS to varying degrees. Conclusions: AIWS is a very complex condition that typically has been described as isolated cases or series of cases.

ABSTRACT Obstructive sleep apnea (OSA) occurs in up to 66% of Parkinson's disease (PD) patients, higher than in the general population. Although it is more prevalent, the relationship between OSA and PD remains controversial, with some studies confirming and others denying the relationship of OSA with some risk factors and symptoms in patients with PD. Objective: To determine the factors associated with OSA in PD patients com DP. Methods: A cross-sectional study was performed with 88 consecutive patients with PD from the outpatient clinic. Participants underwent clinical interviews with neurologists and a psychiatrist, assessment using standardized scales (Epworth Sleepiness Scale, Parkinson's Disease Questionnaire, Pittsburgh Sleep Quality Index and, for individuals with a diagnosis of restless legs syndrome/Willis-Ekbom disease, the International Restless Legs Syndrome Rating Scale), and video-polysomnography. Results: Individuals with PD and OSA were older and had less insomnia than those with PD without OSA. Regarding the polysomnographic variables, we observed a lower percentage of stage N3 sleep, a higher arousal index, and a higher oxygen desaturation index in those individuals with OSA, relative to those without OSA. In the multivariate analysis, only the percentage of stage N3 sleep and the oxygen desaturation index were significantly different. Besides this, most of the PD patients with OSA had a correlation with sleeping in the supine position (58% of OSA individuals). Conclusion: The PD patients showed a high prevalence of OSA, with the supine position exerting a significant influence on the OSA in these patients, and some factors that are associated with OSA in the general population did not seem to have a greater impact on PD patients.
Single incision laparoscopic surgery (SILSTM) using an umbilical hernial approach for cryptorchidectomy of a degenerated testis in a dog

Published: September 2019

ABSTRACT: SILSTM via an umbilical hernia opening was used in the correction of an abdominal cryptorchidism in a dog. The SILSTMport was inserted through a 2.5 cm skin incision on the umbilical hernia and pneumoperitoneum was established with CO2. A 10mm telescope, 5mm laparoscopic Babcock clamp, and a clamp with combined cutting and coagulation features were used for the dissection and removal of the testicle through the SILSTM port. The treatment proved to be effective, easy, and quick to perform. However, the lack of triangulation between clamps and telescope limited the movement of the instruments, making it more laborious than a multiple-trocar approach. It can be concluded that the use of a SILSTM port through a pre-existing opening of the abdominal wall enables a reduction of the risks associated with multiple incisions; such as injury and manipulation of internal organs, pain, bleeding, and development of new hernias.

ABSTRACT: The objective of this research was to establish soil patterns and foliar standards for clonal crops of cocoa CCN51 and PS1319 in the Atlantic regions within the northern Espírito Santo and southern Bahia States. Samples were collected from September to October 2015, in 45 high productive plots, being 23 plots of clone CCN51 and 22 of clone PS1319. Sufficiency ranges for soil and foliar standards were recommended for cocoa clones CCN51 and PS1319 planted in the Northern Espírito Santo and Southern Bahia states. Differences in the contents of foliar macronutrients K, Ca, Mg, S and micronutrients Fe and Mn, were verified between clones CCN51 and PS1319. Differences reported for standards from different geographical regions confirmed that these standards need to be regional and specific for different cocoa clones.
Epidemiology of domestic cat behavioral problems in the city of Porto Alegre/Brazil: a survey of small animal veterinary practitioners
Authors: Albuquerque Nathalia Saraiva de , Soares Guilherme Marques
Published: September 2019

ABSTRACT: The popularity of cats as a companion animal has been growing. Additionally, there is also an increase in the number of complaints regarding behavioral problems associated with the species. Behavioral problems interfere with the animal welfare and quality of people’s lives that are living with them, and are one of the main reasons for abandonment and euthanasia in some countries. This study aimed to investigate the prevalence of behavioral problems among cats with the help of veterinary practitioners in the city of Porto Alegre/Brazil. This evaluation was performed through a questionnaire in veterinary clinics and hospitals of small animals, which was answered by veterinarians responsible for clinical care. The study showed that most veterinarians (92.0%) have been sought to assist with behavioral problems and that dogs were the most consulted species (72.0%). Regarding cats, scratching was the most common owners’ complaints (40.0%), followed by aggressiveness (39.0%), and inappropriate elimination of urine (38.0%). Aggression (73.8%) and scratching (56.9%) were the most frequent reasons that may lead to the abandonment or euthanasia of cats. Results of this research highlighted the importance of having a better understanding about the normal behavior of cats, and the fundamental role of the veterinarian in preventing behavioral problems and abandonment of these animals.

Abstract This study analyzed the changes in the structure of the political network of the footwear Local Productive Cluster (LPC) of Jaú, São Paulo in the period from 1996 to 2016. Network theory was used as theoretical basis because it has gained space in organizational studies in the last decades, besides providing explanations for various phenomena, especially to the study of productive arrangements. The sample involved 90 actors divided into three periods: 1996-2001, 2002-2010 and 2011-2016. For construction of the networks, the software Ucinet and Gephi were used. In addition to a contextual analysis, the ARS metrics (centrality, density, geodesic distance and subgroups) made it possible to identify the interactions among the actors. The results identified structural changes in the network. The number of actors that increased from 29 in the first period to 70 actors in the second period (+141%) and reduced to 39 in the following period (-44%). As for density, it was identified a dense network in the period 1996/2001 and later a diffuse network and pulverized access of information and resources in the periods 2002/2010 and 2011/2016. The central actors were Sindicalçados, Sebrae and directors of the employers' union. The participation of Sebrae and other entities influenced the creation of bonds and provided economic gains to the companies of Jaú, especially in the period 2002/2009, since the entities and the partnerships signed, not only sought the articulation of the entrepreneurs, they often became the protagonists of the changes. However, the decrease in Sebrae's shares as of 2010, has potentiated the reduction of economic indicators such as the number of companies and jobs, when compared to other shoe producing regions in Brazil.
How diseases became “genetic”
Authors: Löwy Ilana
Published: September 2019

Abstract This article examines the origins of the term “genetic disease.” In the late 19 and early 20th century, an earlier idea that diseases that occur in families reflect a vague familiar “predisposition” was replaced by the view that such diseases have specific causes, while Mendelian genetics provided then clues to the patterns of their transmission. The genetictisation of inborn pathologies took a decisive turn with the redefinition, in 1959, of Down syndrome as a chromosomal anomaly, then the development of tests for the diagnosis of other hereditary pathologies. At that time, geneticists distinguished “hereditary” diseases that run in families, from “genetic” conditions that are the result of new mutations during the production of egg and sperm cells. In the latter case, the inborn impairment is produced by an anomaly in the genetic material of the cell, but is not hereditary, because it is not transmitted from one or both parents. In the late 20th and early 21st century, new genomic technologies blurred the distinction between hereditary and genetic impairments, extended the concept of genetic disease, and modified the experience of people living with such a disease.

Published: September 2019

Abstract This study aims to compare the differences between clinical practice guidelines (CPGs) of the Ministry of Health (MoH) and those of other Brazilian health institutions. A systematic review of Brazilian CPGs was carried out. CPGs with recommendations for the pharmacological treatment of non-communicable disease (NCDs) were included. CPG methodological quality and transparency was independently assessed by 2 reviewers using the AGREE II. CPGs were rated as high, moderate, and low quality (ranging from A to C). Twenty-six CPGs were assessed for quality. MoH CPGs were published more recently, and were of better quality than the others: 6/6 (100%) were rated as Moderate-A. Although CPGs presented a wide range of methodological quality and transparency, MoH CPGs presented better consistency in the preparation method. To avoid confusion and to improve the quality of care within finite resources in Brazil, and to avoid potential bias, conflicts of interest, national CPGs used within SUS should be developed by Conitec with partners who have no conflict of interest.
Demanda por contracepção no Brasil em 2006: contribuição para a implementação das preferências de fecundidade
Authors: Carvalho Angelita Alves de
Published: September 2019

Resumo Este estudo buscou estimar a demanda por contracepção no Brasil a partir dos últimos dados disponíveis e identificar possíveis associações entre características sociodemográficas e econômicas das mulheres com a ocorrência desse fenômeno. Para isso, utilizaram-se dados da Pesquisa Nacional de Demografia e Saúde da Mulher e da Criança (PNDS) de 2006 e o método de estimação revisado por Bradley et al. (2012). Apesar do elevado percentual de uso de contracepção no Brasil, estimou-se uma necessidade não atendida por planejamento da fecundidade de 8,3% entre mulheres casadas/unidas de 15 a 49 anos. Isto é, existe um grupo específico de mulheres (no início e no final da vida reprodutiva, de estratos econômicos inferiores, evangélicas e sem religião) que não gostariam de ter mais filhos ou tê-los mais tardiamente e não conseguem fazê-lo devido à falta de acesso aos meios de regulação da fecundidade. Conclui-se que houve uma irrisória redução da demanda em relação à 1996 e com isso, tem-se reforçada a necessidade de investimentos públicos focalizados para que se consiga reduzir os níveis e diferenciais da demanda não atendida por contracepção no país e se tenha garantido os direitos de implementação das preferências reprodutivas.

Abstract Age and growth of two populations of Pugilina cochlidium were studied. to address the lack of basic information on the growth rates and the size at sexual maturity of organism in a commercially harvested area, which will be important in considering the size limits to conserve this resources in future. In the present study the results showed more or less similar growth patterns in the males and females of two populations of Pugilina cochlidium. The age and growth estimation of these two populations of Pugilina cochlidium were completed using several methods and the outcome of one method will act as a check and control over the other using the FISAT 1 software. The values of asymptotic length (Lα) values obtained in the present study using various methods did not vary greatly. Lα values obtained for the first population of Pugilina cochlidium was 95.55 mm for males and 106.05 mm for females and the growth rate (K) for males (0.588 yr-1) and females (0.620 yr-1) was given by k-scan routine in ELEFAN. Similarly, the values of asymptotic length (Lα), obtained for second population of Pugilina cochlidium, was 96.15 mm for males and 106.05 mm for females and the growth rate (K) for males (0.540 yr-1) and females (0.950 yr-1) was given by k-scan routine in ELEFAN.
Wildlife rehabilitation: A case study of the neo-tropical, opossum Didelphis marsupialis insularis, Allen 1902.

Published: September 2019

Abstract Wildlife rehabilitation facilities in the Caribbean region are limited, yet they can provide relevant information on wild populations. Didelphis marsupialis insularis is a popularly hunted, under-studied, neo-tropical marsupial species that is increasingly being admitted for rehabilitation. The aim of this study was 1. To record the experiences of rehabilitating D. marsupialis insularis in the neo-tropical island of Trinidad and Tobago and 2. To extract and highlight information on the biology of this opossum sub-species. Using admission records, obtained over a roughly four year period, two breeding periods (February to March and August to October) were illustrated. Litter sizes averaged five individuals, with a range of 1 to 8 young. This species was found to be common in urban areas of the country, with dog attacks reported as the major cause for admission. Thus the information recorded by this wildlife rehabilitation facility has provided great insight on the sparsely studied opossum, D. marsupialis insularis.

ABSTRACT This study evaluated the compaction of a Bruno Nitisol caused by traffic intensities by a directional feller and skidder used to wood harvesting in a Pinus taeda stand. Data were collected at a forest company located in Parana State, Brazil. Samples were performed using an installation of four blocks (30 × 15 m) with subdivided plots and the treatments included a combination of five traffic simulations of directional feller and skidder machines, with the simulations performed in the plots at four soil depths, referred to as subplots. Compaction was evaluated by soil density, total porosity, microporosity, and macroporosity. The data were submitted to analysis of variance and the means were compared with the Tukey test at a 5% level of significance. Linear regression equations were also adjusted to represent the relation between traffic intensity, depth, and the variable of interest. The results showed that machine traffic caused higher compaction of the superficial soil layers, resulting in a 14.6% increase in soil density compared to the soil subjected to no machine traffic. The increase in traffic intensity of the skidder tractor reduced macroporosity by 62.5% and 53.8% at depths of 0-10 and 10-20 cm, respectively. Dragging of the logs by the skidder tractor increased soil compaction due to the several trips by the machine in a single line.

Authors: Lorenzi Bruno Rossi , Andrade Thales Haddad Novaes de
Published: September 2019

O presente artigo propõe analisar as políticas e as iniciativas nacionais relacionadas com a produção, a pesquisa e o desenvolvimento de etanol de segunda geração (E2G) no Brasil. Utilizando a Teoria Ator-Rede como referencial teórico e metodológico, buscamos identificar, a partir de levantamento bibliográfico e documental, quais são as políticas imbricadas com o E2G, os principais atores que fazem parte dessa rede, suas alianças, as tecnologias relacionadas e as principais questões envolvidas nesse processo. Ao mapear essa rede e acompanhar suas controvérsias, tentamos demonstrar como o E2G ainda é uma caixa-preta aberta a associações de atores humanos e não humanos, políticas e (in)definições. Por fim, apontamos as implicações desse artefato com as políticas relacionadas, buscando contribuir com o debate atual sobre a política energética e a ciência e a tecnologia brasileira.
NEGRITUDE E PAN-AFRICANISMO NO PENSAMENTO SOCIAL BRASILEIRO: A TRAJETÓRIA DE IRONIDES RODRIGUES (1923-1987)
Authors: Barbosa Muryatan S. , Costa Thayná Gonçalves dos Santos da
Published: September 2019

Este artigo tem como objetivo analisar a trajetória e as contribuições do escritor e pedagogo mineiro Ironides Rodrigues aos movimentos negros da diáspora e ao pensamento social brasileiro. Em particular, por sua incorporação da negritude francófona e de certo pensamento pan-africanista em sua luta e reflexão sobre a realidade étnico-racial do negro brasileiro. Para isso, serão examinados escritos diversos (memórias, ensaios, textos analíticos) de sua autoria, que, por não terem sido publicados anteriormente, ainda não foram alvo de pesquisas acadêmicas. A tese deste artigo é que o cerne de sua contribuição prática e teórica à luta negra mundial é sua compreensão da questão negra como direito de autoafirmação, que se consolidou a partir de sua práxis no Teatro Experimental do Negro, nas décadas de 1940-1950.
LAS POLÍTICAS DEL NOMBRE PRÓPRIO: DILEMAS DE REPRESENTACIÓN EN LAS CIENCIAS SOCIALES
Authors: Ascanio-Sánchez Carmen , Rostecka Barbara
Published: September 2019

El objetivo de este artículo es contribuir al debate sobre la representación de los sujetos de estudio en las ciencias sociales y, concretamente, aquel relacionado con las políticas del nombre propio y, por tanto, del anonimato/ identificación o nombramiento. Se debaten las raíces teóricas de dicha práctica y sus implicaciones, tanto en la reformulación del método científico como en los sujetos de estudio y las políticas de representación. Todo ello a través de dos investigaciones empíricas, realizadas por las autoras, dónde estos asuntos requirieron de especial atención. En la discusión se explicitan las divergencias existentes, la utilidad y/o usos de nombrar en procesos de democratización de la investigación y, en especial, la necesidad de una nueva reflexividad ligada a un dialogo más radical entre quiebras del conocimiento, autobiografías críticas y propuestas etnográficas emergentes.

Published: September 2019

Neste trabalho, investigamos os componentes das redes pessoais de agentes prisionais e problematizamos se a maior restrição ao ambiente custodial pode ser vista como um efeito do trabalho em penitenciárias. Para tanto, foram utilizadas as entrevistas em profundidade (realizadas entre 2015 e 2017), com presos e agentes da Região Metropolitana de Belo Horizonte (RMBH), e os questionários sociométricos aplicados a esses mesmos sujeitos. A partir desses dados, comparamos as redes pessoais dos agentes penitenciários com as dos presos, e utilizamos os seus discursos sobre padrões de interação, dentro e fora da prisão, para entendimento das configurações assumidas. Com isso, constatamos que, muitas vezes, os funcionários do cárcere têm redes mais restritas ao universo prisional, do que os próprios internos, o que é descrito por tais entrevistados como um processo de aprisionamento decorrente do trabalho custodial.
