Published: September 2020

The disposition teachers have for resorting to communication and collaboration strategies mediated by Information and Communication Technologies (ICT) is key for establishing academic networks inside and outside the institution either at a national or international levels. With the aim of exploring the complex relationship that may exist between the usages of ICT mediated academic networks and the academic discipline, we have conducted a research on the digital tools Higher Education Educators use to communicate and collaborate with academic purposes. In this article we present the frequency educators use digitals tools and strategies for communicating, socializing and collaborating in Internet depending on the characterization of the academic discipline depending on the hardness of the discipline (soft and hard disciplines) ant its purity (pure and applied disciplines).

Indisciplinando la didáctica. Reflexiones sobre una experiencia filosófico-pedagógica compartida
Authors: Cerletti Alejandro , D’Odorico Gabriela
Published: September 2020

This paper addresses the question of the "Teaching of Philosophy," elucidating, in particular, the possibility of a "Philosophical Teaching of Philosophy" focused, fundamentally, on conceptual creation rather than on the repetition or transfer of some canonical, philosophical knowledge, from teachers to their students. Therefore, the originality of thinking is privileged rather than the repetition of some recipes to learn. As a display of the proposed ideas, some philosophical teaching and learning experiences are described, which are intended to be consistent with these ideas.
Educación insumisa ante el pensamiento único: ¿Quién te vigila?
Authors: Hernández Navarro Carlos Estéban , Cruz Icabalceta Sofía , Rodríguez Soto Luis Miguel
Published: September 2020

In this paper, based on the novel written by George Orwell titled 1984 published in 1948, certain aspects will be analyzed that, when considered in the pedagogical context, could allow the outline of some criteria that contribute to the understanding of the need, in our present time, to propose an educational practice for life, as a political conscience. The objective of supporting human emancipation is pursued, in the fight against a violent system that is reproduced from the educational institutions, which is, due to its actions and selection of techniques, repressive and oppressive.
Educación, comunidad y liberación. Comentarios a partir del pensamiento pedagógico de Paulo Freire y Alejandro Cerletti: aportes a la enseñanza de la filosofía
Authors: Gómez Torres Juan Rafael
Published: September 2020

In this paper, we will give some criteria on the importance of the community as a total social fact necessary to achieve an education that, in addition to being critical and rigorous, is, in turn, pertinent, significant and transformative. For this, we analyze the proposals of Paulo Freire and Alejandro Cerletti to problematize reality through the emergence of the other, or to learn through our questions, considering students from a subject-subject relationship and not as objects of education, who from their reality and needs, can assume education as a liberation process where philosophy plays a fundamental role.
Molecular identification of microbial communities in the methane production from vinasse: A review
Authors: Ordaz-Díaz Luis A. , Bailón-Salas Ana M.
Published: September 2020

Sugars, starches, and cellulose materials are used for ethanol production. When producing a liter of alcohol, 10 to 15 liters of liquid waste are generated. This waste is called vinasse, and it generates negative impacts on the environment. The process of storing and disposing vinasse in soils generates emissions to the atmosphere, mainly methane. Anaerobic treatment allows for the capture and generation of more biogas, therefore allowing mitigation of the environmental impacts. The microbial diversity present in the anaerobic digestion (AD) of vinasse is strongly related to the efficiency and quality of methane production. The gene 16s rDNA-based molecular techniques have been the most commonly used techniques for monitoring microbial communities present in the digesters. However, the identification is not enough. Rather, it is necessary to know the metagenomic functionality in this type of habitat. This review provides a comprehensive overview of methods to identify the microorganisms in the anaerobic digestion of vinasse. In addition, microbial community identification in vinasse reactors and their relationship with methane production are reviewed.

Authors: Fahira Raihan Nurul , Trisnawati Ririn Kurnia , Taufiqurrohman Muhammad
Published: September 2020

The research aims to figure out the gender roles which are used to look at how the film constructs and upholds gender roles. The qualitative method is used to analyze the data in which the primary data are taken from Brad Bird’s Incredibles 2 (2018). Additionally, the researcher used gender roles and cinematography theory to look at how gender is a performance and also to gain a result that gender roles are changing overtimes. The use of Judith Butler’s theory of performativity is to show that the portrayal of gender roles in the movie is slightly different from social construction. Butler’s notion of performativity refers to an act of performance that an individual is doing repeatedly as described in Incredibles 2 (2018) where Bob and Helen do the gender role reversal and share the same responsibilities in the family. Bob is previously shown as the breadwinner of the family and the main earner while Helen is a full-time stay-at-home mother who takes care of the children and the house. Since they no longer hold the traditional gender role; therefore, the movie demonstrates how they start to swap gender assigned tasks. Accordingly, the gender roles are showcased as Bob is being the househusband and the caretaker of the family while Helen is a working woman.

This journal concerns symbols in Trolls Movie by Mike Mitchell. This theme was chosen by the author because the author knows that denotation is examined in the science of signs known as semiotics. Semiotics is part of the study of literature, with symbols that can be anywhere and anytime included in a film. Most of all people watch movies as mere entertainment, without paying attention to other things that come from the show, such as denotation. Here, the author intends to explore how many color denotations in a film, because of their unlimited use. Based on the background of the problem above, the writer chose the film from Mike Mitchell, the Troll film to be analyzed as an object of research. There is one problem statement that the writer found. That is the question of color denotation in the film Troll. Of the three problem statements above, it will be analyzed using two-phase significance by Roland Barthes. By using this theory, denotation will emerge on its own.

Authors: Duangrithi Duangjai , Polsracoo Khuntikun , Bhuddhataweekul Titiwut
Published: September 2020

In the era of highly active antiretroviral therapy (ART), traditional risk factors for metabolic syndrome are presented as increasing age. In low- and middle-income countries, the restricted benefit package of national health security for human immunodeficiency virus (HIV) does not facilitate the early detection of metabolic disorders. In order to assess the rational of national health security for metabolic abnormalities among people living with HIV (PLHIV), this retrospective study aims to determine the occurrence of metabolic abnormalities and its predicting factors. The study was approved by the hospital ethics committee and conducted at the internal medicine clinic, Pathum Thani Hospital, Thailand. Patients with HIV having had at least 1 year of first-line ART, and having their fasting glucose, fasting lipid profile, and blood pressure assessed before ART were recruited into the study. Those with any abnormal metabolic component prior to ART or absent history of ART were excluded. The metabolic abnormalities were defined as any of the following: elevated triglyceride, reduced high-density lipoprotein (HDL), elevated blood pressure, elevated fasting glucose, or on drug treatment for these metabolic abnormalities. The occurrence of metabolic abnormalities was found in 102 of 340 patients (30.0%). Hypertension (11.4%) was the most common abnormality. Age became the single predictor of metabolic abnormalities (odds ratio [OR] = 1.03, 95% confidence interval [CI] = 1.00–1.06). Aging patients with HIV should be the target group for monitoring and treating metabolic abnormalities. The revision of the benefit package on metabolic abnormalities is urgently needed to promote a better quality of life.

Prisons and Drug Abuse Correctional Centre (DACC) play a significant role in recidivism. This study aims to understand the role of prisons and DACC in drug user recidivists, the implementation of Law no. 12 of 1995 concerning correctional facilities, and the law. No. 35 of 2009 concerning narcotics to find out how the process of guidance in prisons and DACC for drug user recidivists, and to find out the effectiveness of coaching in both prisons. This qualitative research uses a case study approach. The data collection method used interviews with 8 subjects and observations on the subject and prison conditions. The data analysis method combines the analysis stages of Morse and Miles and Huberman. Purposive sampling technique was used, with the criteria of the research subjects: drug user recidivists; have experienced convictions in prisons and DACC; of legal age; case of article 127 of Law no. 35 of 2009 concerning Narcotics or article 36 of Law No. 5 of 1997 concerning Psychotropics and in conjunction with other articles; BI and BIIa classification; the level of drug use is not addiction. The results showed that these two laws have not been fully implemented in prisons and DACC. This is evidenced by the different treatment of prison officers, while the treatment of DACC officers is the same and more humane to DACC so that it has an impact on recidivism. In both, there is personality development and independence but still emphasizes religious development. Medical and social rehabilitation is perceived as ineffective. The two correctional institutions do not raise self-contempt but do raise a cognitive bias. Prison and DACC are different environments that play an important role in becoming drug user recidivists, but DACC is an environment that is more conducive to achieve the correctional goals for drug user recidivists
Uma Estratégia de Desenvolvimento com Estabilidade
Authors: Bresser-Pereira Luiz Carlos , Nakano Yoshiaki
Published: September 2020

RESUMO A retomada do crescimento econômico após 20 anos de quase estagnação depende de uma estratégia de crescimento que combine estabilidade macroeconômica com políticas orientadas para o crescimento. O Plano Real estabilizou os preços, mas, como contrapartida, a taxa de juros disparou enquanto a taxa de câmbio permanece artificialmente apreciada. O principal desafio é reduzir a taxa básica de juros, que é consideravelmente mais alta que a dos países com classificação de risco-país semelhante. Existem várias razões para isso, incluindo pouca preocupação das autoridades monetárias em reduzir a taxa de juros, e a relação inversa entre a taxa de juros e o risco de default: a alta taxa de juros definida pelo Banco Central influencia em alta o risco-Brasil.
Prêmio de Risco Endógeno, Metas de Inflação e Câmbio Flexível: Implicações Dinâmicas da Hipótese Bresser-Nakano para uma Pequena Economia Aberta*
Authors: OREIRO JOSÉ LUÍS
Published: September 2020

RESUMO O objetivo deste artigo é analisar as implicações da hipótese de Bresser-Nakano, de que o prêmio de risco é positivo em relação à taxa de juros - ao longo do tempo, trajetórias de taxa de juros nominal e taxa de câmbio nominal em uma pequena economia aberta cujo regime de política econômica é caracterizada por taxas de câmbio flexíveis, metas de inflação e mobilidade de capital de curto prazo. No arcabouço teórico desenvolvido no artigo, podemos demonstrar que, no caso de um forte feedback positivo da taxa de juros nominal sobre o prêmio de risco, (i) existem múltiplos caminhos temporais da taxa de juros nominal e da taxa de câmbio nominal; (ii) todos esses caminhos são compatíveis com algum grau de estabilidade de preços e (iii) alguns desses caminhos, no entanto, estão relacionados a um aumento no déficit em conta corrente e/ou um aumento contínuo no déficit fiscal. A conclusão lógica desses resultados é que a conquista da conta corrente e do equilíbrio fiscal só pode ser obtida com uma mudança no regime da política econômica.

Published: September 2020

RESUMO O artigo examina alguns aspectos constitutivos do capitalismo do ponto de vista histórico e institucional. O argumento básico desenvolvido no artigo é que a constituição de um modo de produção especificamente capitalista implica a imposição de algumas instituições cujo significado geral é a dissolução das particularidades típicas do mundo pré-moderno. O resultado desse processo é uma sociabilidade pseudo-universal, cuja principal instância é o fetichismo das mercadorias.

Authors: França Karla Eveline Ximenes de , Vilela Mirella Bezerra Rodrigues , Frias Paulo Germano de , Sarinho Silvia Wanick
Published: September 2020

ABSTRACT Objective: To compare 2012 and 2016 data on early neonatal near miss indicators from Health Information Systems at a university hospital. Methods: This is a cross-sectional study conducted in 2012 and 2016. We considered early neonatal near misses the live births that presented one of the following risk conditions at birth: gestational age <33 weeks, birth weight <1,750g or 5-minute Apgar score <7, or Neonatal Intensive Care Unit (NICU) admission, and were alive until the 7th day of life. Data were collected from the Live Birth Information System, Hospital Information System, and Mortality Information System. We calculated the early neonatal mortality rate, neonatal near miss rate, severe neonatal outcome rate, early neonatal survival index, and early neonatal mortality index, compared by year of birth. Results: In 2012, 304 early neonatal near misses were registered, with a higher proportion of cases with very low birth weight and mothers who had zero to three prenatal visits. In 2016, the number of cases was 243, with a predominance of more NICU admissions. The incidence of early neonatal deaths and early neonatal near misses was higher in 2012 than in 2016. Conclusions: Neonatal near miss indicators identified difference between years. The cases were more severe in 2012 and there were more NICU admissions in 2016.
Not all viruses in nature are human enemies: a perspective on aquatic virus ecology in Brazil

Published: September 2020

Abstract: Viruses cause various diseases in humans through vector-borne (e.g., Zika and dengue fever), airborne (e.g., measles) and water-borne (e.g., hepatitis) transmission, as well as direct physical contact (e.g., AIDS and herpes). Recently, the new coronavirus (SARS-CoV-2) pandemic has triggered the greatest global health crisis in a century. However, not all viruses in nature are human enemies. A vast body of literature indicates that viral infection is vital for ecosystem functioning by affecting nutrient cycling, controlling species growth and enhancing biodiversity. Here we provide a perspective on the ecological role of viruses in nature, with special focus on Brazilian aquatic ecosystems.
The Parameterized Complexity of Motion Planning for Snake-Like Robots
Authors: Gupta Siddharth , Sa'ar Guy , Zehavi Meirav
Published: September 2020

We study the parameterized complexity of a variant of the classic video game Snake that models real-world problems of motion planning. Given a snake-like robot with an initial position and a final position in an environment (modeled by a graph), our objective is to determine whether the robot can reach the final position from the initial position without intersecting itself. Naturally, this problem models a wide-variety of scenarios, ranging from the transportation of linked wagons towed by a locomotor at an airport or a supermarket to the movement of a group of agents that travel in an “ant-like” fashion and the construction of trains in amusement parks. Unfortunately, already on grid graphs, this problem is PSPACE-complete. Nevertheless, we prove that even on general graphs, the problem is solvable in FPT time with respect to the size of the snake. In particular, this shows that the problem is fixed-parameter tractable (FPT). Towards this, we show how to employ color-coding to sparsify the configuration graph of the problem to reduce its size significantly. We believe that our approach will find other applications in motion planning. Additionally, we show that the problem is unlikely to admit a polynomial kernel even on grid graphs, but it admits a treewidth-reduction procedure. To the best of our knowledge, the study of the parameterized complexity of motion planning problems (where the intermediate configurations of the motion are of importance) has so far been largely overlooked. Thus, our work is pioneering in this regard.

Eremophilus mutisii (Humboldt, 1805) es un pez endémico del altiplano cundiboyacense, cuya categoría de amenaza actual es vulnerable. El programa nacional para la conservación de esta especie sirvió de base para el plan de conservación en la jurisdicción CAR Cundinamarca de 2018. Este plan se sustentó en el diagnóstico del estado de conservación de la especie presentado en este estudio. Para ello, se investigó su distribución geográfica a partir de colecciones biológicas y salidas de campo a ecosistemas acuáticos previamente identificados por la CAR y el grupo investigador. Se evaluó la presencia de E. mutisii en los ríos Suárez, Bogotá (cuenca alta), Ubaté, Veraguas, Frío, Aguas Claras y Muña, y en la laguna de Fúquene y los embalses del Neusa y Tominé, mediante un protocolo de muestreo basado en la pesca eléctrica y la toma de parámetros fisicoquímicos. El esfuerzo de pesca fue de 0,044 y 0,054 individuos/hora para los ríos y lagunas (o embalses), respectivamente. Se capturaron en total 17 individuos, 53% fueron adultos, 41% juveniles y 6% alevines. La relación longitud-peso encontrada indica que el coeficiente de crecimiento de la especie fue alométrico positivo. Se corroboró que E. mutisii se distribuye geográficamente en un rango altitudinal de 2540–3000 m s. n. m., aunque no se registró en las cuencas de los ríos Bogotá, Veraguas, Ubaté, Suárez y Frío. El declive de estas poblaciones se debe principalmente a factores antrópicos, como la transformación y fragmentación de los ecosistemas, la introducción de especies invasoras y la contaminación de los cuerpos hídricos.
Introducing Security to Efficient Tree-based Self-organizing Protocol
Authors: Kerimov V. O.
Published: September 2020

Wireless sensor networks are widely used in many modern settings. In order to build substantial networks each sensor must be cheap. So it follows that, since resources of individual sensor are limited, there is a need to create protocols that would use them sparingly and evenly in order to maximize lifetime of the network. To reach this goal some useful self-organizing tree-based protocols were created that use different properties of the network nodes, such as number of children, number of hops from the ultimate sink, distance and remaining energy, to optimally select and reselect parent node in a network. However, there is also a challenge of providing security of the network. In this paper we propose a way of integrating a simple security method akin to iterative filtering into the protocol and discuss corresponding trade-off between attack prevention and increase of energy consumption.
S-boson production in the reaction of Coulomb scattering of a nucleus by a proton or electron
Authors: Barabash O. , Kovtoniuk V. S.
Published: September 2020

The production cross-section of the beyond the standard model (BSM) scalar boson (S boson) have been considered it the article. Scalar boson produced via photon fusion reaction in the deep inelastic scattering of a charged particle (proton or electron) on heavy nucleus of the target. This process is one of the possible mechanisms of BSM boson production at the SHiP (Search for Hidden Particles) experiment at the CERN LHC and may be dominating among others processes due to large nuclear charge. Previously [1], the amplitude and the production cross-section of this reaction were found. The found cross-section was analyzed for the case of proton scattering on the lead nucleus and compared with the production cross-section in the decay of Ds meson. In this paper we make estimate of the process more accurate and consider also electron-nucleus scattering. It was found that the photon fusion reaction pZ \to S may be effective only in the case of massless S boson.

THERMO-HYDRAULIC PERFORMANCE ANALYSIS OF PARABOLIC CONCENTRATING SOLAR WATER HEATER
Authors: BHAKTA Amit Kumar , SİNGH S.n.
Published: September 2020

This paper concerns the thermo-hydraulic performance analysis of a PCSWH (parabolic concentrating solar
water heater) with placing the PTT (perforated twisted tape) in the absorber tube. The experiments are performed
using water as testing fluid. In this analysis, the mass flow rate changes from 0.0326 kg/s to 0.0667 kg/s and
Reynolds number ranges from 2100 to 4250 respectively. The analysis is based on the effect of porosity of the PTT
and mass flow rate over the pressure drop and heat transfer enhancement during the flow into the absorber tube of
the PCSWH. At last to guess the increment in pressure drop and enhancement of heat transfer the empirical
correlations for friction factor and the Nusselt number have been formulated considering the turbulent effect caused
by PTT inside the absorber tube. The major observations of this analysis are that PTT enhances the pressure drop and
heat transfer and also both enhances with increasing porosity of the PTT.

Tests were conducted for turbulent flow, using air as medium through a uniformly heated steel pipe containing a novel kind of insert named as Conical offset Vortex Generator (COVG). The simulation tests were performed for turbulent flow with varying Reynolds number in the range 4000 to 50000. The parameters were analyzed during tests are pitch to smooth tube diameter ratio (p/d) and angle of attack (α). Various simulation tests were carried out with the help of ANSYS Fluent software to optimize the geometry. The simulation tests were carried out for different angle of attack (α = 15°, 30°, 60°). COVG with angle of attack (α = 60°) shows more enhancement in heat transfer rate, hence it was used for the experimentation purpose. The experimentation is conducted for various pitch to diameter (p/d = 1.18, 1.97, 3.94). The numerical and experimental results show improvement in heat transfer rate as there is decrease in pitch to smooth tube diameter ratio (p/d) and it also increases the value of friction factor. The reason behind the improvement in heat transfer rate is that, the braking of thermal boundary layer near the wall surface. Experimental results show the enhancement of Nusselt number from 3.46 – 6.7.

The connecting rod is the intermediate component between the piston and the crankshaft, and its primary function is to move the up and down from the piston pin to the crankshaft converting the reciprocating motion into rotary motion of the piston and crankshaft.

This study describes a numerical analysis of connecting rod for determining the critical stress regions. During the analysis of connecting rod, loads corresponding to different engine speeds were assumed to be statically applied, and their corresponding stress and deformation values were evaluated. The power and torque values of engine were utilized to be used as the load boundary conditions in static simulation model, other parameters those of used as input values were geometric dimensions of connecting rod and its material properties.

Numerical analyses were performed for the connecting rod made of SS 304 material. A 3D CAD model was developed for the connecting rod through the SOLIDWORKS software, then drawn solid model was transferred to the ANSYS software with Workbench module. Von mises stress and deformation analyses were evaluated under the different engine speeds with indicating that connecting rod did not failure and fractured under the applied external loads.

In current study, exhaust emission, vibration and noise features of diesel engine with addition of metallic based nanoparticles into diesel fuels were investigated experimentally. Various nanoparticles called as silver (II) nitrate (AgNO3), manganese (II) nitrate hydrate (Mn(NO3)2. xH20) and nickel(II) nitrate hexahydrate (Ni(NO3)2.6H2O) were used as an additive to diesel fuel at 25 ppm and 50 ppm dosing level so as to obtain six different fuel samples. Diesel engine with air-cooled and a single cylinder were utilized for engine tests altering engine speed from 1200 to 2800 rpm at the intervals of 400 rpm. The results demonstrated that of the nanoparticle addition did not remarkably affect the physicochemical features of the diesel test blends. But, the addition of nanoparticles slightly raised viscosity, cetane number and the heating value of test fuels especially, at the higher nanoparticle concentrations. In all experiments, with nanoparticle added blend fuels, CO, HC, NOx emission values and brake specific fuel consumption (BSFC) declined in parallel with the increase in nanoparticle concentration. In addition, it was shown that the Sound Pressure Level (SPL) and vibration characteristics of the engine block also decreased with increasing nanoparticle concentration of test fuels. As a result, AgNO3 addition to diesel fuel has an effective role in both reducing emission and vibration values and reducing BSFC values.

Ischemic heart disease is the leading cause of mortality that raised the demand for pre-hospital emergency care in Sri Lanka. Understanding the performance of Sri Lanka's 1990 Suwa Seriya ambulance service is essential to improve its quality and to reduce morbidity and mortality associated with the disease. This study aims to describe socio-demographic characteristics and evaluate the clinical assessment and management process of patients presenting with acute chest pain of cardiac in origin. A descriptive study was conducted in Gampaha District of the Western Province of Sri Lanka. A total of 154 records of patients with acute chest pain who rang the 1990 call centre over a 3-month period were selected. Composite values for treatment and examinations as a percentage were plotted on run charts to assess the performance and its variations over the study period. About 47.4% of the study group were in 35–65 age group, 53.2% were males, and 81.8% had a typical presentation. The median for composite value for examination as a percentage was 89.5%, indicating substantial control and alignment with the reference package with normal cause variation. The median composite value for treatment as a percentage was 9.96%, a low value with normal cause variation. A good control of the processes of clinical examination and treatment is apparent. A higher median for composite value for examination as a percentage attributed to the formal training process of the ambulance staff. Although a low median was obtained for the composite value for treatment as a percentage, it was stable and pointed room for improvement.
The limits of magic: A study in breaking through barriers in fantasy fiction
Authors: Poradecki Mateusz
Published: September 2020

The article analyses the theme of magic in the works of Andrzej Sapkowski (the Witcher series) and Jarosław Grzędowicz (Pan Lodowego Ogrodu) in terms of their potential, limitations, and the social consequences of using them. Magic is a genre-forming element of fantasy fiction, yet in most works – e.g. Tolkien’s The Lord of the Rings or Robert E. Howard’s Conan series – readers do not learn about it more than they do from fairy tales. Magic is subject to extensive descriptions much later, i.e. in the works by Sapkowski and Grzędowicz. In Sapkowski’s texts, it is a natural force of nature, which is studied and developed by the members of an academy. In Grzędowicz’s novel, it is a highly advanced technology, often mistaken for spells by the fairly undeveloped inhabitants of the planet Midgard. Magic is an attempt at breaking through barriers enforced by the laws of nature as well as social barriers. An uncontrolled development may lead to the self-annihilation of an entire civilisation.
