Authors: Mohiddin M. N. , Saleh A. A. , Reddy A. N. R. , Hamdan S.
Published: October 2018

Biodiesel is one of the promising renewable sources to fulfill the future energy demand of the world. Sustainable feedstock for biodiesel production is one of the major criteria to ensure the process of renewability. Chicken fat is an encouraging feedstock for biodiesel. In this study, waste chicken fat was converted to biodiesel via catalysed transesterification. Optimised process parameters were recorded at 1:4 oil-to-methanol volume ratio and 0.5 wt% KOH catalyst concentration with a biodiesel yield of 96%. The FT-IR spectral analysis of chicken fat and chicken fat biodiesel confirmed the conversion of chicken fats into biodiesel. The physico-chemical properties of biodiesel were tested in accordance with ASTM D6751 and EN 14214 biodiesel standards. The specific fuel properties of chicken fat biodiesel that include calorific value, viscosity and acid value were found to be lower than that of petrodiesel. The diesel engine performance tests confirmed that the biodiesel blends performance was similar to petrodiesel.  It is noted that while the brake horsepower increased with the increase of biodiesel blending percentage, the engine power output was found to decrease. Specific fuel consumption also increased along with the biodiesel blending percentage.

Authors: Kumara Pavana , Purohit G. K.
Published: October 2018

Roller burnishing process was carried out on free cutting brass materials in the presence of fine silicon carbide abrasives in the form of paste on a pre-machined surface. The results of ‘without-paste’ burnishing (plain burnishing, PB) and ‘with-paste’ burnishing (abrasive assisted burnishing, AAB) processes are compared to examine the effect of abrasive particles in the burnishing process. A 24 full factorial design is adopted to develop the mathematical model for surface roughness regarding four process parameters like burnishing force, burnishing speed, burnishing feed and number of passes for both the cases, i.e. PB and AAB. Analysis of variance (ANOVA) was carried out to find the effect of process parameters and to check the adequacy of the models. The results show that the parameters have a significant effect on the response in PB to improve the surface roughness by 75 % than the turned components. Whereas in AAB, fine abrasive particles as a single entity controlling the response and making other parameter effects as non-significant. Surface roughness further improved by 15 % in AAB process.
Air Flow Thermal and Dynamic Behavior Inside Ventilated Cavities
Authors: Harnane Y. , Bouzid S. , Brima A.
Published: October 2018

This work presents a numerical study of the dynamic and thermal behavior of the air flow circulating in the vertical rectangular cavity of height H and width W. The geometry consists of a vertical wall of low thermal conductivity and an opposite wall which acts as a ventilated facade with five openings subjected to a heat flow. The methods of analyzing the flow input and output behavior through the openings throughout the ventilated facade, make the use of CFD tools "Fluent 14.0" mandatory for a detailed description. The flow is considered to be turbulent, steady, incompressible and bi-dimensional and computations are performed using the standard k-ε and RNG k-ε models for Rayleigh number ≈ 1011. The results included mean velocity profiles; flow structure and thermal field which were presented and discussed. A comparative study with conventional cavity (closed) and classical cavity with two openings (input-output) under the same thermal conditions was conducted to quantify energy savings by the use of such configuration. The increase of the number of the openings enhances the wall cooling. Moreover, above a certain heat flux absorbed by the ventilated wall, natural cooling is obsolete, it is necessary to use forced devices.
Low Temperature Machining of Nitrile Rubber
Authors: Rajesh Nayak , Akshay Nayak , Raviraj Shetty
Published: October 2018

This paper presents an innovative methodology to improve machining of nitrile rubber. The research comprises of turning of nitrile rubber under ambient (dry) and low- temperature (dry ice) condition against HSS cutting tool. Individual machining force data for all the tests were documented with the help of a Kistler dynamometer. The low temperatures freeze the material previous to machining so that it cannot alter or adhere to the cutting edge, thus resulting in low wear on the edge and improved machining. To achieve a stable condition for the rubber machining, a mandrel was designed to hold the rubber workpiece.  It was observed that 36.19% reduction in cutting force, 6.08% decrease in radial force and 23.3% drop in feed force were obtained when cutting was made at low-temperature machining as compared to dry cutting with cutting speed increased from 162.58 m/min to 226.19 m/min, with 1 mm depth of cut and tool feed of 0.5 mm/rev. This concludes that a remarkable decrease in cutting force value can be obtained by adopting low-temperature cooling. Thus, this new approach concludes that dry ice machining of nitrile rubber should be amended in a directive to acquire better machining results.

Thyroid hormone (T3) and its receptor (TR) are involved in cancer progression. While deregulation of long non-coding RNA (lncRNA) expression has been detected in many tumor types, the mechanisms underlying specific involvement of lncRNAs in tumorigenicity remain unclear. Experiments from the current study revealed negative regulation of BC200 expression by T3/TR. BC200 was highly expressed in hepatocellular carcinoma (HCC) and effective as an independent prognostic marker. BC200 promoted cell growth and tumor sphere formation, which was mediated via regulation of cell cycle-related genes and stemness markers. Moreover, BC200 protected cyclin E2 mRNA from degradation. Cell growth ability was repressed by T3, but partially enhanced upon BC200 overexpression. Mechanistically, BC200 directly interacted with cyclin E2 and promoted CDK2–cyclin E2 complex formation. Upregulation of cell cycle-related genes in hepatoma samples was positively correlated with BC200 expression. Our collective findings support the utility of a potential therapeutic strategy involving targeting of BC200 for the treatment of HCC.
Role of Cis, Trans, and Inbreeding Effects on Meiotic Recombination in Saccharomyces cerevisiae
Authors: Raffoux Xavier , Bourge Mickael , Dumas Fabrice , Martin Olivier C , Falque Matthieu
Published: October 2018

Meiotic recombination is a major driver of genome evolution by creating new genetic combinations. To probe the factors driving variability of meiotic recombination, we used a high-throughput method to measure recombination rates in hybrids between SK1 and a total of 26 Saccharomyces cerevisiae strains from different geographic origins and habitats. Fourteen intervals were monitored for each strain, covering chromosomes VI and XI entirely, and part of chromosome I. We found an average number of crossovers per chromosome ranging between 1.0 and 9.5 across strains (“domesticated” or not), which is higher than the average between 0.5 and 1.5 found in most organisms. In the different intervals analyzed, recombination showed up to ninefold variation across strains but global recombination landscapes along chromosomes varied less. We also built an incomplete diallel experiment to measure recombination rates in one region of chromosome XI in 10 different crosses involving five parental strains. Our overall results indicate that recombination rate is increasingly positively correlated with sequence similarity between homologs (i) in DNA double-strand-break-rich regions within intervals, (ii) in entire intervals, and (iii) at the whole genome scale. Therefore, these correlations cannot be explained by cis effects only. We also estimated that cis and trans effects explained 38 and 17%, respectively, of the variance of recombination rate. In addition, by using a quantitative genetics analysis, we identified an inbreeding effect that reduces recombination rate in homozygous genotypes, while other interaction effects (specific combining ability) or additive effects (general combining ability) are found to be weak. Finally, we measured significant crossover interference in some strains, and interference intensity was positively correlated with crossover number.
Tempo e História em Santo Agostinho
Authors: Julião José NICOLAO
Published: October 2018

O objetivo principal deste ensaio é o de apresentar como se constituiu um modelo teológico da filosofia da história em Santo Agostinho que tem a Providência divina como o seu princípio de determinação, o tempo linear sucessivo como a sua forma de desenvolvimento e a salvação como a sua finalidade. Para o proposto, focamos nossa análise em A Cidade de Deus, especialmente, nos livros de XI a XXII e nas Confissões, no livro XI, acerca do tempo. Apresentamos a seguinte estratégia expositiva em nossa interpretação: 1°, analisamos o entendimento que Agostinho tem do conceito de tempo, como sentido interno na alma e sucessivo em sua relação com a eternidade, exposto no livro XI das Confissões, para melhor, compreendermos a ideia de tempo linear progressivo projetada em A Cidade de Deus como fio condutor da história humana; 2°, nós interpretamos a distinção estabelecida pelo autor na origem, entre duas cidades, a de Deus e a terrena, enfatizando que há uma tensão entre ambas, entre o bem e o mal, em decorrência do livre-arbítrio humano, que faz com que história se desenvolva. 3º, por fim, consideramos o processo de desenvolvimento e os fins das duas cidades, narrada na perspectiva bíblica da ação dos grandes patriarcas em suas relações de obediência e desobediência a Deus, ligando à história progressiva da salvação.
Da justiça como princípio de vontade igualitária para a justiça como aumento de potência. Nietzsche e a justiça como meio de inversão da má consciência em aumento da potência afirmadora da vida
Authors: Feiler Adilson Felicio
Published: October 2018

Conceber a justiça como princípio que iguala, é colocar-se no processo contrário ao aumento da vida. É esta a ideia principal que se depreende dos escritos de Nietzsche, em especial, em Humano, demasiado humano e Para a Genealogia da moral. Compreendida como jogo de forças, a vida se eleva na medida em que, a ela, se opõe obstáculos, como é o caso da violência, da guerra, da ofensa e da exploração. À medida em que a justiça sacraliza a vingança, eleva os afetos reativos, colocando-se numa posição de hostilidade à promoção da vida. Pelo contrário, à justiça cabe romper com aquela instituição da lei que somente enxerga a proposição do prejudicado, para colocar-se ao lado do ser humano ativo, violento e excessivo. À justiça se liga, portanto, um valor biológico que eleva e estimula os afetos ativos que querem dominar e possuir, de modo a inverter a má consciência em boa consciência, substituindo a vingança e o ressentimento pela afirmação das forças. Em que medida a justiça, que lida sob este prisma biologicista, é capaz de dar conta daquilo que lhe compete enquanto promoção do bem comum?
A Ontologia da Semiformação em tempos de neoliberalismo
Authors: Pucci Bruno
Published: October 2018

Este artigo se propõe estabelecer um diálogo com o ensaio Teoria da Semiformação, de Theodor Adorno, escrito em 1959, no contexto do capitalismo do bem-estar social. O objetivo é ressaltar sua atualidade na abordagem da crise da formação cultural contemporânea, em que prevalece a forma de capitalismo neoliberal e, ao mesmo tempo, detectar novas nuances constitutivas da referida teoria nesse momento histórico. Nessa trajetória, o texto percorrerá os seguintes passos: a Teoria da Semiformação como um diagnóstico da crise da formação cultural no final da década de 1950; as formas de como a ontologia da semiformação se constitui em tempos de neoliberalismo; as novas roupagens com que essa crise cultural vai se instalando progressivamente nas salas de aulas; e a necessidade de se lhe contrapor novas manifestações de resistência. O artigo buscou apoio teórico em Dardot e Laval (2016) para captar as especificidades do neoliberalismo contemporâneo.

Some linguistic features of the Old Kashmiri language of the Bāṇāsurakathā
Authors: Verbeke Saartje
Published: October 2018

The Bāṇāsurakathā is a sharada manuscript in Old Kashmiri composed by Avtar Bhatt, dated between the 14th and 16th centuries. It retells the love story of the demon Bāṇa’s daughter Uṣā with Krishna’s grandson Aniruddha, and the ensuing fight between Bāṇa and Krishna, as it is found in the Harivaṃśapurāṇa. This paper focuses on the linguistic features of the Old Kashmiri language in which this manuscript is composed. Old Kashmiri belongs to the Early New Indo-Aryan language stage, a stage crucial for a number of syntactic developments which determined the Indo-Aryan languages of today. First, the language found in the Bāṇāsurakathā is situated among the attestations of Old Kashmiri found in other manuscripts. The language is younger than that of the Mahānaya-Prakāśa, but older than the language used in the Lallā-Vākyāni. Second, a number of linguistic features of Old Kashmiri are presented, such as the case marking and the verb agreement. Third, the paper focuses on the phenomenon of pronominal suffixation, well known in Modern Kashmiri, but not present in Apabhraṃśa. It is shown that the first traces of pronominal suffixation already existed in the Bāṇāsurakathā, but their use was not yet grammatically fixed.
Supplements to the theoretical reconstruction of the articular church of Vadosfa
Authors: Danielisz Dóra , Krähling János
Published: October 2018

Articular church architecture is a less-researched subfield of the Hungarian architectural history. Beyond some memories of particular interest – such as the Lutheran church of Nemeskér – the memories of early Protestant architecture in the area of today’s Hungary and their influences are largely unknown to us. This paper aims at studying and preparing the theoretical reconstruction of an articular church no longer existing today. The church building of Vadosfa, standing between 1732 and 1911, is the subject of our study, in connection with which the most important sources are the demolition protocols available in the diocese’s archives. By reviewing, analyzing and utilizing the data of the still unpublished archival sources with the use of a new methodology, new knowledge will enrich the image of the articular church architecture in Hungary. We attempt to evoke the old articular church of Vadosfa. The results of the theoretical reconstruction, and the summaries of architectural relationships provide an opportunity to review and expand our knowledge of the regional types of articular architecture.
A study on the relationship between exercise addiction, abnormal eating attitudes, anxiety and depression among athletes in Israel
Authors: Levit Maayan , Weinstein Ayelet , Weinstein Yitzhak , Tzur-Bitan Dana , Weinstein Aviv
Published: October 2018

Background and aims

The aim of this study was to investigate the relationship between exercise addiction, abnormal eating attitudes, anxiety, and depression among competitive and amateur athletes.

Methods

Participants were 100 athletes of mean age 28.3 years (18–62), of which there were 67 males and 35 females. The sample consisted of competitive and amateur athletes who participated in individual and group sports. They filled in the Exercise Addiction Inventory, Body Shape Questionnaire, a questionnaire assessing Eating Attitudes Test, Spielberger State-Trait Anxiety Inventory, and Beck Depression Inventory (BDI).

Results

Ratings of exercise addiction were positively correlated with BDI scores across the study sample. Exercise addiction ratings were associated with abnormal eating attitudes, but not with trait or state anxiety. Athletes engaging in individual sports scored marginally higher on depression scores than group athletes but there was no difference in depression scores between competitive and amateur athletes. Multiple regression analysis revealed that abnormal eating attitudes contributed significantly to ratings of exercise addiction and explained 7.7% of the variance. According to the Sobel test, the difference in the association between exercise addiction and eating disorder was significant. Therefore, body shape was a mediating factor between eating disorder and exercise addiction.

Discussion and conclusions

This study extends our preliminary findings of an association between exercise addiction and depression. Second, abnormal eating attitudes may explain most of the variance of exercise addiction. This is a further support for previous evidence of comorbidity between exercise addiction and eating disorders.

Authors: Martinotti Giovanni , Chillemi Eleonora , Lupi Matteo , Risio Luisa De , Pettorruso Mauro , Giannantonio Massimo Di
Published: October 2018

Introduction

Gambling disorder (GD) is a major public health concern with currently no validated and efficacious treatments approved. In this single case study, we report the short- and long-term effect of bilateral transcranial direct current stimulation (tDCS) of dorsolateral prefrontal cortex (DLPFC) on craving and impulse control in a subject with GD.

Methods

The patient is a 26-year-old Caucasian male with an 8-year history of GD as well as alcohol and cocaine misuse. Treatment consisted of twice-a-day stimulation for 10 days. According to the literature, both the left (to control craving) and the right (to control emotional impulses) DLPFC were stimulated. Patients subsequently received tDCS once a week for 3 months and then once every 2 weeks for another 3 months.

Results

After 10 days of treatment, the subject reported improved psychiatric symptoms (depression, anxiety, and impulsivity), as well as reduced gambling craving symptom severity. After 3 and 6 months of treatment, the clinical picture further improved.

Discussion

This is the first report of tDCS effectiveness in a single case study of GD. Therapeutic effects, both on the addictive behavior and on psychiatric comorbid symptomatology, were lasting and continued over 6 months of tDCS maintenance treatment. Future case–control studies are required to test the efficacy of this tool in patients with GD.
Does level of training predetermine the success rate of prehospital sepsis assessment? A prospective survey on early recognition
Authors: Kanizsai P , Molnár GY , Sztudva R , Berényi T , Hornyák I
Published: October 2018

Introduction

Sepsis is a challenge for health professionals. The increasing number of cases emphasizes the importance of early recognition resulting in better survival.

Materials and methods

Questionnaires were spread focusing on the prehospital recognition, treatment, and care pathway of septic patients. After presenting an initial scenario, other sepsis-like diseases were given as diagnosis of choice and the answers were registered. After redefining the situation, the same potential diagnoses were given and the difference in correct answers was detected.

Results

The number of responders was 120. Among them, 33% of responders chose hypovolaemia, 10% allergic reaction, 2.5% endocrine disease, 30.8% systemic inflammatory response syndrome/sepsis, 0.83% internal bleeding, 0.83% drug effect, 2.5% pulmonary embolism, and 19.17% metabolic disorder as primary diagnosis with a significantly higher number of trained paramedics highlighting the correct answer. After redefining the scenario, 63% changed the diagnosis, while 37% did not change (p < .001). Further management was correctly chosen by the majority of responders.

Discussion

The small number of correct answers from non-paramedics highlights the need for more education in identifying the pitfalls of early recognition and therapy of those who attend patients first.

Conclusion

Trained paramedics recognize the sepsis better than other representatives, necessitating the introduction of new guidelines.
THE MEANING OF ACOSMIA IN ARISTOTLE, POLITICS II, 1272b1-16
Authors: Laffon Amarande
Published: October 2018

La palabra griega acosmia, en oposición a cosmos, se refiere al desorden y a la mala conducta a nivel físico, moral o social. En Política de Aristóteles II, 1272b1-16, la palabra acosmia es usada en la descripción de las instituciones cretenses. En este contexto particular, se han dado interpretaciones contrapuestas para el término acosmia, en la medida en que Cosmos es también un título de magistrado en Creta. Examinaré aquí las cuestiones filológicas y filosó­ficas planteadas por este uso puntual de “acosmia”.

ABSTRACT Objective: to reflect on the medicalization process of childbirth and birth and its consequences based on a Brazilian audiovisual media artifact. Method: reflective and interpretive analysis of the documentary O Renascimento do Parto (The Rebirth of Childbirth) based on Critical Discourse Analysis. Results: c-section emerges as an alternative to adverse conditions of pregnancy. However, it has become a routine and abusive practice of a medicalized obstetric care, thus becoming a social problem. In order to the incidence of c-sections decrease, women's protagonism must be restored, in addition to considering psychological, affective, emotional, spiritual, cultural, and contextual aspects in childbirth. Conclusion: childbirth is established as a material element and a mental phenomenon of social practices. We must interrupt the predominant model, allowing the body to express itself through the release of oxytocin, and decrease the segregation that c-section causes, thus enabling affective bonds.

ABSTRACT Objective: To present a reflection on the forms of violence in health care settings and on preventive actions. Method: This is a theoretical reflection about the phenomenon of violence and its possible coping actions. Results: Nurses and other professionals working in health care environments may experience situations of aggression and disrespect through institutional or managerial violence, horizontal violence and patient violence. Final considerations: Violent practices are not applicable in any workplace, especially in care settings. Actions or measures of control should be taken in pursuit of healthier environments and in harmony with the culture of peace.
A paradigmatic visionary perspective: professional master's in nursing
Authors: Souza Cláudio José de , Silvino Zenith Rosa
Published: October 2018

ABSTRACT Objective: To reflect on the key concepts of the book The Structure of Scientific Revolutions and its applicability in professional master's in nursing. Method: This is a theoretical-reflective study that uses the philosophical and epistemological conceptions of the philosopher Thomas Samuel Kuhn to consider its applicability on the paradigm shift of stricto sensu graduate courses in nursing. The main concepts of Kuhn were used as support: paradigm, anomaly, scientific community and scientific revolution. Results: The propositions of this philosopher are applied to and support the theoretical reflection on professional master's programs, contributing to clarify what would be a paradigmatic visionary perspective in stricto sensu master's models in nursing. Conclusion: From Kuhn's propositions it was possible to conclude that professional master's programs in nursing can break away from the dominant paradigm, strengthening a scientific revolution within the academia.
Radiation-induced angiosarcoma of the breast: a retrospective analysis of 15 years' experience at an oncology center
Authors: Alves Ines , Marques José Carlos
Published: October 2018

Abstract Objective: To characterize a population of patients with radiation-induced angiosarcoma (RIAS) of the breast treated at an oncology center, focusing mainly on the imaging features, although also on the clinical presentation, diagnosis, and management. Materials and Methods: We performed a retrospective review of patients with histologically proven angiosarcoma of the breast or chest wall, all of whom received radiotherapy, after conservative or radical breast surgery, between 2000 and 2015. Results: Eleven patients met the inclusion criteria. The median age at the time of diagnosis of RIAS of the breast was 71.5 years (range, 58-87 years), and the median latency period was 8.9 years (range, 4-27 years). The rate of local recurrence was 54.4%, RIAS recurring after a median period of 10 months (range, 3-18 months), and distant metastases occurred in three patients (27.3%). All of the tumors were accompanied by skin changes, and a palpable mass was seen in four. Most of the imaging findings were nonspecific. Six patients underwent magnetic resonance imaging, which revealed pronounced skin enhancement in all six. Ultrasound-guided core needle biopsies were negative in three of the eight patients. Conclusion: RIAS of the breast is a rare but recognized complication of radiotherapy for breast carcinoma, with a poor prognosis and high recurrence rate, which requires a high index of suspicion for a prompt diagnosis.

RESUMO Objetivou-se verificar o potencial de folhas de girassol mexicano (Tithonia diversifolia) como alternativa de manejo ao nematoide Pratylenchus brachyurus em quiabeiro. Foram conduzidos dois ensaios em casa de vegetação, em delineamento inteiramente casualizado, com sete repetições, sendo cada parcela composta por um vaso contendo uma planta. Utilizou-se o quiabeiro como planta indicadora e o sorgo como testemunha suscetível. Os tratamentos foram cinco níveis de fitomassa verde e seca (0, 5, 10, 15 e 20 g kg-1 de solo) de T. diversifolia, incorporada ou na forma de cobertura do solo, para avaliar o efeito sobre a população de P. brachyurus. A incorporação de folhas frescas de T. diversifolia no solo, como adubo verde, reduziu a população de P. brachyurus 60 dias após a inoculação, com destaque para o nível de 20 g kg-1 de solo que possibilitou reduzir a população do nematoide (FR=0,00). Com 5 g de fitomassa seca, em cobertura, de T. diversifolia foi possível reduzir 2,96 % a população do nematoide, enquanto que os níveis de fitomassa seca de 10, 15 e 20 g kg-1 de solo eliminou o patógeno. Conclui-se que a incorporação ao solo de folhas frescas de T. diversifolia, e a cobertura morta com folhas de T. diversifolia sobre o solo, na forma de fitomassa seca, proporcionaram redução na população de P. brachyurus no solo e nas raízes de quiabeiro, sendo uma alternativa importante para o manejo de P. brachyurus
Reflexo econômico e desenvolvimento da resistência de Phakopsora pachyrhizi a fungicidas em função do número de aplicações
Authors: Reis Erlei Melo , Reis Andrea Camargo , Zanatta Mateus
Published: October 2018

RESUMO O objetivo do controle de doenças de plantas com fungicidas é minimizar os danos causados à cultura, incluindo a redução de produção. No entanto, o uso de fungicidas impacta no custo de produção e aumenta o risco de seleção de linhagens de fungos resistentes. Esses dois fatores são dependentes do número de pulverizações. Atualmente, no uso de fungicidas na cultura da soja visando, principalmente, ao controle da ferrugem (Phakopsora pachyrhizi) não se adota qualquer critério científico, para definir quando efetuar a primeira aplicação. Nessa revisão é abordada a importância do monitoramento das lavouras de soja, da diagnose e da quantificação de danos causados pela ferrugem. Apresentam-se os principais indicadores empíricos para a primeira aplicação e o critério científico. A ocorrência da resistência cruzada e múltipla de P. pachyrhizi aos fungicidas sítio específicos carboxamidas, estrobilurinas e triazóis pode ter sido acelerada pelo uso desnecessário de aplicações desses fungicidas.
Assessment of grain discoloration in the main rice genotypes of Corrientes Province, Argentina
Authors: Dirchwolf Pamela Maia , Gutiérrez Susana Alejandra , Carmona3 Marcelo Aníbal
Published: October 2018

ABSTRACT Rice grain discoloration affects grain yield and quality. Corrientes is the main rice producing province in Argentina. Previous studies were carried out in this province, where only panicle incidence (PI) was evaluated. In view of the need to obtain more agronomic parameters to more exhaustively investigate the effects caused by this disease, the present study was carried out to evaluate panicle incidence (PI), percentage of discolored grains per panicle (GD), weight loss (WL), disease severity index (DSI) and sterility (S) in eight rice genotypes. Although PI and GD are estimated as disease incidence, both were significantly different. GD is obtained by the grain-by-grain evaluation, while PI considers a panicle diseased when the latter presents at least one spotted grain; thus, this last method overestimates the disease incidence. The genotype IRGA 424 recorded maximum and minimum GD and S values, which may be explained by different sowing dates in different regions in the province, with their corresponding environmental conditions during the critical period of the infection and during spikelet formation. WL and DSI had lower values than those reported by other authors, which indicates that the effects of rice grain discoloration on these parameters in Corrientes Province, Argentina, are less severe than in other rice cultivating countries.
QUÉ PUEDE DECIRNOS LA RELATIVIDAD GENERAL RESPECTO DE LA FLECHA DEL TIEMPO
Authors: LÓPEZ CRISTIAN
Published: October 2018

Resumen Tradicionalmente, desde la filosofía de la física el problema de la flecha del tiempo ha sido abordado en términos de las propiedades que exhiben las leyes físicas fundamentales ante determinadas operaciones, en particular, ante la operación de inversión temporal: si las leyes permanecen invariantes ante inversión temporal, entonces no es posible distinguir un sentido temporal privilegiado desde un punto de vista físico; por el contrario, si una determinada ley no permanece invariante ante inversión temporal, mediante esa ley es posible dar un argumento físico para sostener la existencia de una flecha del tiempo. Sin embargo, esta estrategia ha conducido a numerosos problemas y ha instalado un clima escéptico en el ámbito de la filosofía de la física respecto del potencial de las ciencias físicas para recoger la idea intuitiva de un tiempo asimétrico. En el presente artículo se busca mostrar que la relatividad general constituye un fructífero y prometedor campo de discusión filosófica respecto del problema flecha del tiempo, campo aún no suficientemente explorado. Se argumentará que para abordar esta problemática en el terreno de la relatividad general, es necesario dejar de focalizar en las propiedades formales de las leyes físicas y en el concepto de invariancia temporal, para orientar nuestra búsqueda hacia las propiedades del espacio-tiempo.
A irredutibilidade das paixões em Descartes
Authors: Andrade Érico
Published: October 2018

Resumo: O presente artigo tem como objetivo central apresentar uma visão alternativa para o debate sobre o dualismo cartesiano mente e corpo. Nessa perspectiva, vou sustentar a tese de que o dualismo de substâncias cartesiano está presente apenas na metafísica cartesiana e não serve para explicar a condição humana, marcada, notadamente, pelo composto mente e corpo. Desse modo, vou procurar mostrar que as paixões ou emoções, responsáveis por nossos estados mentais, são decorrentes da interação entre a mente e o corpo e, de modo nenhum, podem ser reduzidas à mente ou ao corpo, tomados separadamente. Elas são propriedades que emergem, no sentido heterodoxo do termo emergência, da relação da mente com o corpo.
Repetição, negação e ideologia. Marx, Hegel e o problema do sujeito
Authors: Laureano Pedro
Published: October 2018

Resumo: Este artigo parte da análise da influência de Hegel na construção do conceito de capital e de ideologia, na obra de Marx. Para tal, buscou-se analisar a passagem dos primeiros escritos humanistas de Marx à sua teoria tardia. Da ruptura realizada por Marx em relação a suas obras de juventude, surge o problema de como determinar o sujeito, uma vez que a perspectiva humanista inicial é abandonada. A ideia é a de que, paradoxalmente, quando critica a dialética hegeliana, Marx termina por encontrar problemas que poderiam ser resolvidos através de conceitos hegelianos, como a questão do sujeito de classe. É o que procuraremos argumentar por meio de uma análise sobre o papel da negatividade em Hegel.
Descobrindo Modelos de Previsão para a Inﬂação Brasileira: Uma Análise a partir de uma Gama Ampla de Indicadores
Authors: Silva Anderson Moriya , Marçal Emerson Fernandes
Published: October 2018

Resumo Este trabalho visa avaliar o poder preditivo que séries macroeconômicas têm sobre o índice de preços ao consumidor amplo brasileiro (IPCA) utilizando técnicas de séries de tempo. As previsões são realizadas para um horizonte de até 12 períodos à frente e comparadas com um processo autoregressivo como referência. O período vai de janeiro de 2000 até agosto de 2015. Utilizou-se um conjunto amplo de informação de 1170 séries. Para cada momento e horizonte de tempo selecionou-se um novo modelo utilizando o algoritmo Autometrics desenvolvido por Hendry e Doornik (2014). O desempenho preditivo dos modelos foi comparado utilizando o Model Confidence Set, desenvolvido por Hansen, Lunde and Nason (2010). Os resultados sugerem que há ganhos expressivos de previsão principalmente para os horizontes mais longos.
