EFFECT OF DOSAGE OF REDISPUTABLE POWDERS AND THE TYPE OF LOW-MODULAR INCLUSIONS ON THE PROPERTIES OF FINE-AGGREGATE CONCRETE
Authors: Dolgova A. V. , Nesvetaev G. V.
Published: August 2019

Objectives Reliability and durability of structures using materials with various properties (plaster coatings, cement glue, new concrete during repair and restoration of structures, etc.) largely depends on the adhesion of the layers and the deformation properties of the coatings. To obtain the required properties of materials used for coatings, modifiers based on polymers and low-modulus inclusions are introduced into the composition of new concretes, for example, entrained air. The aim of the work is to identify some patterns of change in the properties of concrete with the joint introduction of these modifiers.

Method Experimental determination of the tensile strength in bending, compression, E-modulus, adhesion to the concrete base by standard methods.

Result The influence of separate and joint introduction of dispersible polymer powders and various low-modulus inclusions into the composition of fine-grained concrete has been established.

Conclusion The joint introduction to the composition of fine-grained concrete of various low-modulus inclusions and redispersible polymer powders provides a reduction in the stress level during forced deformations due to the different effects additives on the strength and deformation properties and contributes to increased adhesion to the concrete.
MODELS FOR DETERMINING MAXIMUM DEGREE FILLING CHANNELS OF CIRCULAR SECTION SHAPE
Authors: Alibekov A. K. , Аlibekov G. A.
Published: August 2019

Objectives The task was to obtain a model for determining the maximum possible degree of filling the circular section channels in the earthen channel based on the condition of ensuring the stability of slopes and the minimum volume of excavation during their construction, as well as finding the optimum degree of filling fortified channels of a closed profile corresponding to maximum throughput.

Method In work analytical methods of differential calculus and the solution of implicit equations are used.

Result The experience of domestic and foreign researchers was taken into account to solve the set tasks, select research methods and criteria for optimizing channel parameters. Two cases of circular-shaped channels are considered: 1) in the earth channel, 2) reinforced with a closed transverse profile. For the case of a hydraulically most advantageous circular channel in the earthchannel channel, equating the first derivative of the equation of a circle with the reciprocal of the allowable embedding coefficient of the slopes obtained an analytical solution for determining the maximum degree of filling from the slope stability condition, which was not dependent on hydraulic flow elements. In the case of non-cohesive soils that form the channel, the circular channel can be filled to a depth not exceeding 20 percent of the channel radius. At the same time, the average flow rate should remain in the range from non-venting to non-blurring. In order to be able to determine the flow rate, analytical expressions are given for finding hydraulic flow elements in a circular channel. When determining the volume of excavation for the construction of the channel, the excess of the channel edge above the maximum water level in the channel was taken into account. For the case of a fortified channel of a closed transverse profile, by taking the derivatives from the Chezy formula, we obtained the optimal values of flow rate and average velocity.

Conclusion A fortified closed circular profile channel has a maximum capacity with a relative degree of filling of 0.938, and the maximum average velocity of a fluid in a pressureless channel is achieved with a degree of filling of 0.815. To determine the maximum permissible relative degree of filling in the case of a circular section channel in the earthen channel, analytical dependences were obtained, before using which, according to the reference literature, it is necessary to take the value of the slope coefficient for this type of channel bed soil.
VERBAL MODEL OF MANAGEMENT OF A VULNERABLE PROCESS OF DEDICATING THE ACCESS OF USERS TO THE SOFTWARE OF THE ELECTRONIC DOCUMENT SYSTEM
Authors: Alferov V. P. , Drovnikova I. G. , Obukhova L. A. , Rogozin E. A.
Published: August 2019

Objectives Traditional methods for solving the problem of protecting the information resource of electronic document management systems based on protective basic functions (identification, authentication and verification of users, etc.) of available tools and information security subsystems have a significant drawback - inefficiency when an attacker masters the password of regular users. In order to eliminate it, it is necessary to develop new methods related to managing the weakly vulnerable process of delimiting user access not only to confidential information, but also to the software of the electronic document management system.

Method One way to solve this problem is to use the modified “soft administration” method, which consists in automatically generating lists of allowed source files in the authorization matrix by reducing the lists and comparing file integrity functions with a reference list for an existing software package. This allows you to automate the process of developing access control rules and provide management of the weakly vulnerable process of access control to software tools of the electronic document management system.

Result A verbal model is developed for automated control of a weakly vulnerable process of differentiating access to software tools of an electronic document management system, and a system of performance indicators for the functioning of a promising subsystem for protecting confidential information characterizing it as a control object is proposed.

Conclusion The presented verbal model provides for the possibility of distributed control, in which the security administrator directly controls the specified process using a remote software tool. The formation (change) of the authority establishment matrix for managing a weakly vulnerable process of access control using a promising subsystem for protecting confidential information and the development of a system of indicators to comprehensively evaluate the effectiveness of its functioning is one of the most important tasks of protecting information from unauthorized access, guaranteeing the implementation of a security policy throughout the entire operation period secure electronic document management system.
Extraordinary Renditions and State Secrets: A Human Rights Approach
Authors: Borenstein Juliana Gil
Published: August 2019

One of the world’s main concerns over the past decades has been the phenomenon of terrorism. It is evident that terrorism must be eradicated, especially considering the huge threat it poses to the basic values of democratic societies. However, it must be kept in mind that arbitrary governments also represent a huge threat to these same values and, therefore, safeguards must exist to guarantee that state authorities act within the framework of law. Unfortunately, some governments misuse the ‘state secrets privilege’ argument, created to protect their right to confidentiality in national security affairs, to prevent their gross violations of human rights from being assessed by the judiciary, violating victims’ rights and promoting impunity. This is particularly true in cases involving so-called ‘extraordinary renditions’ used to fight terrorism. This article defends the premise that as much as the existence of secrecy is essential for the protection of every nation, no secrecy can serve as an excuse for governments to violate human rights and disregard the rule of law. In order to ensure that state secrets privilege is not used as a way to promote impunity for serious human rights violations, it is very important that mechanisms are implemented in order to have the claim of secrecy in national security related issues closely scrutinised by an impartial judicial organ. It is in the interest of democracy and justice that a fair balance is struck between the interests of national security and the protection of human rights.
Seeking the Golden Fleece through Lampedusa: Situating Municipal Action in International Law
Authors: Eruaga Osatohanmwen OA
Published: August 2019

The crises of illegal migration by sea, currently plaguing the coastal States around the Mediterranean Sea, have created a situation of tightening border controls. Italy, as a choice destination State for many migrants, has continued to employ measures to ensure that the number of vessels carrying irregular migrants arriving onshore is reduced to the barest minimum. Push-back measures, which are conducted based on bilateral agreements with Libya, are one such method of seaward border management. This article questions the legality of the Italian push-back measures, as a representation of State interest, when placed next to international law. The paper argues that, since such measures of externalisation of border security may conflict with principles of international law, destination States should consciously adopt measures that are sensitive to migrant rights.
Wading in Troubled Waters: Supporting the Work of the International Criminal Court (ICC) through Domestic Legal Institutions in Kenya
Authors: Juma Laurence
Published: August 2019

This article discusses the role of Kenyan domestic legal institutions in supporting principles and institutions of international criminal justice. It discusses how these legal institutions have interacted, supported and even applied the principles of international criminal justice amidst a very hostile political climate. This article argues that the current calls for withdrawal from the Rome Statute of the International Criminal Court may be frustrated by these institutions because they have greater affinity to the principles of international criminal justice than political establishments. While acknowledging that the eradication of impunity should be a joint effort between domestic and international institutions and that the current tensions and calls for withdrawal are not good for everyone, the article argues that neither international institutions alone nor domestic systems can make progress unless there is collaboration as well as reforms in the entire international criminal justice system.
Emerging Legal Issues in Sub-Orbital Flight and Colonization under International Air and Space Law
Authors: Nkum King James , Julius Beida Onivehu
Published: August 2019

Space exploration activities constitute an important part of International Air and Space Law. Space Law, which governs matters in outer space beyond the Earth's atmosphere, is a rather new area of law and is to a very large extent connected to Air Law. Not only have we witnessed a tremendous increase in air travel recently, human activities in space has also skyrocketed. Sub-orbital flight and colonization (also known as space tourism) is one of such developments in space activities today and is not without legal implications. This article seeks to x-ray and situates some of these legal issues emerging out of contemporary space exploration activities against the overarching framework of the UN Space Treaties.
The Role of the Energy Charter Treaty in Fostering and Promoting Energy Efficiency and Sustainable Development
Authors: Masumy Naimeh
Published: August 2019

The paper aims to critically analyze whether the Energy Charter Treaty (hereafter “ECT”) can be considered a viable instrument to foster and safeguard the concept of sustainable development, whilst simultaneously promoting foreign investment. First, an overview of the investment protection regime under ECT will be set out, assessing whether or not the ECT ensures that investments are in line with environmentally sound practices. Secondly, this study examines whether references to energy efficiency and environmental concern could signify that this treaty does not only place importance on investment protection, but also considers energy efficiency an equally important objective.  Subsequently, this paper will argue that whilst the ECT can be read as promoting sustainable development, this goal is often not realized when the ECT provisions are applied in reality. Finally, the article will propose some reforms that could be made to the ECT which ensures observing key issue related to energy efficiency and sustainable development.
A New Dawn? Statelessness and Assam
Authors: Paulose Regina Menachery
Published: August 2019

This article explores the ongoing crisis of statelessness that has been created because of a petition made by the people of Assam, India to update the electoral rolls in the state. As a result of the process, which has been approved by the Supreme Court of India, an estimated 4 million people have become stateless. The government has stated that these 4 million people risk deportation back to Bangladesh. This article will briefly examine the history of the situation that has unfolded in Assam; discuss the role of statelessness and how it may lead to genocide, underscoring the importance to act and find robust solutions. Finally, the author will conclude by discussing potential actions that India should take in order to resolve future cases of statelessness, specifically examining the Global Compact on Refugees and other instruments provided for within international refugee law.

Objetivo. Evaluar el efecto de dosis crecientes del glucósido cianogénico Linamarina, en la reducción de metano ruminal in vitro. Materiales y Métodos. Se empleó líquido ruminal de dos ovejas fistuladas de la raza Merino Precoz, con el que se inoculó un sustrato fermentativo constituido por heno de alfalfa (Medicago sativa) y grano de avena molido (Avena sativa L.), se adicionó solución buffer y Linamarina (pureza de ≥98%) en dosis crecientes, lo que se llevó a incubación por ocho horas in vitro. El metano se midió cada hora, con un monitor de gases infrarrojo. Resultados. De acuerdo con el incremento de las dosis de Linamarina (0, 6, 13, 20 y 26 mg/L), la concentración de metano disminuyó de forma lineal (p≤0.05) en (9.7, 9.2, 18.1 y 29.4%) respectivamente. Se observó una reducción significativa de metano con la dosis más alta de Linamarina. Conclusión. La Linamarina, en su estado puro, fue eficaz en la reducción de metano durante la fermentación ruminal in vitro. Por lo tanto, este estudio constituye una base para futuros experimentos que incluyan fuentes vegetales de Linamarina y otras variables ruminales, lo que puede conducir a encontrar estrategias para reducir los gases de efecto invernadero.
Evaluación de la resistencia bacteriana frente a tres antibióticos usados en la maduración del camarón marino (Litopenaeus vannamei).
Authors: Luna G. Diana , De León L. Jorge , Vallejo I. Adriana , Velásquez L. Gustavo
Published: August 2019

La incidencia de las enfermedades bacteriana en camaronicultura, ha conducido a la utilización de terapéuticos, con el subsecuente problema de generación de resistencia a mediano y largo plazo, afectando la producción. Con el objetivo de evaluar la resistencia bacteriana en un sistema de maduración de Litopenaeus vannamei , fueron aisladas 18 cepas bacterianas correspondientes a V. parahaemolyticus (n=3), V. alginolyiticus (n=5), V. hollisae (n=5) y Flavobacterium spp. (n=5). La resistencia a antibióticos oxitetraciclina, trimetoprim-sulfa y ciprofloxacina, fueron evaluados siguiendo la metodología de Kirby-Bauer; la concentración mínima inhibitoria (MIC) se determinó según los métodos normalizados (Comité Nacional para las Normas de Laboratorio Clínico – NCCLS). El 66% de las cepas de V. parahaemolytucus , resultaron resistentes a la oxitetraciclina con una MIC entre 7.81 y 15 µg.ml -1 . El 40% de las cepas de V. hollidae presentaron

resistencia a este antibiótico con una MIC entre 3.9 y 7.81 µg.ml -1 para trimetrprim-sulfa y concentraciones entre 0.06 y 0.25 µg.ml-1 para ciprofloxacina. Como conclusión se advierte en este estudio la resistencia a la oxitetraciclina en las cepas de V. arahaemolyticus y V. hollisae , potencialmente patógenas para camarones. Tanto trimetoprim – sulfa como ciprofloxacina resultaron ser efectivos para la inhibición de todas las cepas bacterianas evaluadas; no obstante trimetroprim-sulfa requirió dosis hasta de 8µg.ml -1 , situación que hace poco práctico su uso por los costos y el riesgo de generar resistencia. Se recomienda el uso de ciprofloxacina solamente para casos especiales con el fin de evitar el desarrollo de cepas bacterianas resistentes arriesgando la salud pública veterinaria. Se sugiere estudios complementarios para otros antibióticos de uso en la Acuicultura.
Desempeño reproductivo del bocachico (Prochilodus magdalenae, Steindachner, 1878) inducido en un mismo año.
Authors: Mar P. Elkin , Petro M. Roberto , Atencio G. Víctor
Published: August 2019

Prochilodus magdalenae es la principal especie pesquera continental y la cuarta cultivada en Colombia. En su ambiente natural se reproduce en el cauce principal de los ríos, en el período lluvioso y lo hace una sola vez al año. No se reproduce en confinamiento por lo que la obtención de semillas para los programas de repoblamiento y fomento piscícola se obtienen mediante inducciones hormonales, principalmente con extracto pituitario de carpa (EPC). Para mantener la oferta de alevinos durante gran parte del año algunas estaciones productoras de semillas en la región inducen a una misma hembra por lo general dos veces al año. No se conocen estudios evaluando y comparando el desempeño reproductivo entre la primera y la segunda inducción hormonal. El objetivo de este estudio fue evaluar el desempeño reproductivo del bocachico sometido a dos inducciones hormonales con EPC durante el mismo año
Intraindividual Variability Measurement of Fine Manual Motor Skills in Children Using an Electronic Pegboard: Cohort Study
Authors: Rivera Diego , García Antonio , Ortega Jose Eugenio , Alarcos Bernardo , van der Meulen Kevin , Velasco Juan R , del Barrio Cristina
Published: August 2019

Background

Pegboard tests are a powerful technique used by health and education professionals to evaluate manual dexterity and fine motor speed, both in children and adults. Using traditional pegboards in tests, the total time that, for example, a 4-year-old child needs for inserting pegs in a pegboard, with the left or right hand, can be measured. However, these measurements only allow for studying the variability among individuals, whereas no data can be obtained on the intraindividual variability in inserting and removing these pegs with one and the other hand.

Objective

The aim of this research was to study the intraindividual variabilities in fine manual motor skills of 2- to 3-year-old children during playing activities, using a custom designed electronic pegboard.

Methods

We have carried out a pilot study with 39 children, aged between 25 and 41 months. The children were observed while performing a task involving removing 10 pegs from 10 holes on one side and inserting them in 10 holes on the other side of a custom-designed sensor-based electronic pegboard, which has been built to be able to measure the times between peg insertions and removals.

Results

A sensor-based electronic pegboard was successfully developed, enabling the collection of single movement time data. In the piloting, a lower intraindividual variability was found in children with lower placement and removal times, confirming Adolph et al’s hypothesis.

Conclusions

The developed pegboard allows for studying intraindividual variability using automated wirelessly transmitted data provided by its sensors. This novel technique has been useful in studying and validating the hypothesis that children with lower movement times present lower intraindividual variability. New research is necessary to confirm these findings. Research with larger sample sizes and age ranges that include additional testing of children’s motor development level is currently in preparation.
Curriculum, Assessment and Pedagogy: How These Dimensions are Enriching Visual Arts Education for Ethnically Diverse Students in New Zealand Secondary Schools
Authors: Smith Jill
Published: August 2019

This article reports on findings from two complementary research projects conducted in Auckland, New Zealand’s largest city. Both projects were motivated by changing demographic statistics from a largely European-ethnic student population in secondary schools in the past, to an ethnically diverse one in the present. Each project focused upon the nature of New Zealand’s national curriculum and assessment policies for visual arts education, and the pedagogical practices of art teachers. European-ethnic art teachers comprise the majority in secondary schools, thus the research in 2015 centred on how these teachers are working alongside ethnically diverse students. Given that there is a growing population of Asian-ethnic students in secondary schools, the follow-up project in 2018 focused on how art teachers of Asian ethnicity are supporting these students to engage in experiences that express their cultural identities. The findings provide evidence of how art teachers are using the curriculum, assessment policies and culturally responsive pedagogies to enrich the nature of visual arts education for students of all ethnicities in secondary schools in this country. The findings are exemplified through the ‘voices’ of a sample of art teachers, and ‘artworks’ by 15-18 year old students which encapsulate the role of images as a powerful form of data.
Presidential Power, Vetoes, and Public Policy: a Comparative Study between Brazil and the United States
Authors: Hebling Matheus Lucas , Contrera Flávio

[Poder presidencial, vetos y política pública: Un estudio comparativo de Brasil y Estados Unidos]

ABSTRACT

Much of the literature on Presidentialism focuses on the argument that bipartisan presidential systems are better able to avoid a conflictive Executive-Legislative relationship by facilitating the formation of coalitions in Congress and partisan ideological identification. From a comparative perspective, this study aims to identify and discuss the ability of the presidents of the United States and Brazil to promote public policy, and to examine the degree of conflict in the drafting of these policies by studying legislative vetoes. In addition, it analyzes the success rate of welfare bills voted in the lower chamber of the two countries and supported by their respective presidents. The period studied here covers 16 years (from 1995 to 2010 in Brazil and in the United States from 1993 to 2008), consisting of eight years of more liberal administrations and eight years of more conservative ones in each country. The presented hypothesis is that there is no significant difference between two-party or multi-party systems in terms of conflict, public policy drafting and presidential success rate. The data are analyzed using multivariate regressions and undergo qualitative treatment for a deeper understanding.

RESUMEN

Gran parte de la literatura sobre el presidencialismo se centra en el argumento de que los sistemas presidenciales bipartidistas son más capaces de evitar una relación conflictiva entre ejecutivo y legislativo al facilitar la formación de coaliciones en el Congreso y la identificación ideológica partidista. Desde una perspectiva comparativa, este estudio tiene como objetivo identificar y discutir los poderes de los presidentes de los Estados Unidos y Brasil para promover políticas públicas y verificar el grado de conflicto en la producción de dichas políticas mediante el control de los vetos legislativos. Analiza también la tasa de éxito de los proyectos de leyes de políticas de bienestar votadas en la cámara baja de los dos países y respaldados por sus respectivos presidentes. Abarca un período de 16 años (de 1995 a 2010 en Brasil y en los Estados Unidos de 1993 a 2008), con ocho años de administraciones más liberales y ocho años de gobiernos más conservadores en cada país. La hipótesis es que no hay una diferencia significativa con respecto al conflicto y la producción de políticas públicas en sistemas bipartidistas o multipartidistas y que las tasas de éxito son similares. Los datos se analizan mediante regresiones multivariables y se someten a un tratamiento cualitativo para una comprensión más profunda.
Lo político entre democracia y comunalidad
Authors: Wolfesberger Philipp
Published: August 2019

En el contexto de un sistema político en el que la democracia atraviesa por una crisis de representación y por un proceso de despolitización, coexisten experiencias de los pueblos indígenas en México que muestran, desde la resistencia, otras formas de pensar la vida comunitaria. Por medio de un estudio teórico se analiza la relación de la dimensión de lo político de la democracia con la comunalidad. Se discute la noción de poder solidario, derivado de la autoridad comunal indígena, como propuesta central de un concepto de poder no jerárquico, pero mandatorio y colectivo. La interrelación de diferentes epistemologías contribuye a un avance necesario de la teoría de la democracia y la democracia radical, y enfatiza, asimismo la necesidad de diálogos teóricos interculturales sobre la comunidad y lo político.
Instituciones y educación en México: bienes preferentes, movilidad social y premodernidad
Authors: Millán Valenzuela Henio , Pérez Archundia Eduardo
Published: August 2019

La educación es un bien meritorio o preferente y, al mismo tiempo, un bien meritocrático. La tarea de cualquier sistema educativo es conducir la transición entre estas dos dimensiones. Cuando la sociedad es muy heterogénea, esta tarea suele fallar. Este trabajo tiene como objetivo probar los fallos en esta transición, para lo cual se examina el caso de México, cuyo sistema político ha exhibido la necesidad de mantener el equilibrio entre actores modernos, premodernos y posmodernos, a fin de sortear con éxito el dilema entre gobernabilidad y democracia. La solución ha sido el divorcio entre instituciones formales e informales. Este divorcio ha propiciado la desactivación de todo intento de impulsar el conocimiento a través de la educación porque permite la prevalencia de mecanismos informales que gozan de gran legitimidad, en virtud de que así lo exige el equilibrio entre actores sociales.

Factors Of The Formation Of New Autonomous Regions And Its Impact On State Finances
Authors: Maulana Arief
Published: August 2019

The purpose of this study is to analyze the driving factors of the formation of new autonomous regions in Indonesia during the reformation era and its impact on state finance. This study is a policy study by collecting data and then analyzing it into a conclusion and recommendation. This type of study is a literature study with the method used is descriptive qualitative method. The results of the study show that since the reform era, the formation of a new autonomous region has been very massive. If calculated on average from 1999 to 2014, each year the new regions increase by 13 regions per year. The formation of the new autonomous regions requires considerable preparation and costs, starting from the initial formation to the implementation. In addition, in general the new autonomous regions show higher fiscal dependencies than the old regions. Thus, it can be stated that the establishment of the new autonomous regions has caused pressure on the state finances due to the large amount of funds that must be transferred to new regions.

Published: August 2019

This research focuses on how several internal factors influence the company’s stock prices through the company analysis and based on previous studies that have often been done with no consistent results. The purpose of this research is to analyze the size of the company, sales growth, CR, NPM and ROE as a review of the company's share prices on the Indonesia Stock Exchange's LQ45 Index. This research used a purposive sampling technique. Before employing the data analysis, a classic assumption test was performed. The hypothesis testing was carried out using multiple regression analysis. The results showed that the size of the company, sales growth, the NPM, and the ROE affect the stock prices, whereas the CR does not affect stock prices.
THE DEVELOPMENT OF CAPACITY BUILDING TO IMPROVE THE QUALITY OF HUMAN RESOURCES AMONG SMALL AND MEDIUM ENTERPRISES
Authors: Amboningtyas Dheasy , Yulianeu Yulianeu
Published: August 2019

Small and medium enterprises (SME) are those of business groups which are believed to survive even when economic crisis occurs. The increasing number of those business groups allows more job opportunities for people, and thus it could impact positively towards the decreasing number of unemployments. Unfortunately, the level of managerial skills and ability among SME are relatively low due to a number of SME entrepreneurs who still hold Bachelor degrees. In addition, the fact indicates that the quality of SME resources is low, especially in the fields of management, organization, mastery of technology and marketing. The low educational level among small and medium entrepreneurs was apparently not supported by capacity building through training, education, and programmed comparative studies. On the other hand, human resources (HR) also plays an important role in gaining success, because sophisticated and complete facilities cannot guarantee the success of an organization if they are not supported by quality of human resources who will use the facility. This study aims at examining strategies that can be used by SME as an effort to improve HR capacity using purposive sampling method; and then the data is analyzed using multi-linear regression. The result shows that capacity development which is proxied through education, skills and ability variables partially or simultaneously have positive and significant effects on HR development.
Fazendo a Base virar realidade: competências e o germe da comparação

Published: August 2019

Neste texto, foco, especificamente, em um conjunto de materiais que se dedica a “fazer a Base virar realidade nas salas de aula”, produzido por uma articulação entre o MEC, as secretarias de educação e entidades do terceiro setor. Parto de uma noção pós-fundacional de política, segundo a qual toda hegemonia é marcada, desde o seu interior, por uma fratura e precisa, portanto, seguir sendo reinstituída. Dedico-me a entender como a noção de competência geral, que passou a estruturar a Base pós-impeachment, vem sendo significada no momento atual. Argumento que há um alinhamento da política educacional do País à governança da OCDE baseada na comparabilidade que, defendo, inviabiliza a educação como empreitada intersubjetiva. Por fim, sugiro o uso de outras referências para a construção de uma base de valorização profissional e condições de infraestrutura para uma educação de qualidade.

Evaluación de FeCl3 y PAC para la potabilización de agua con alto contenido de color y baja turbiedad
Authors: Yanza-López Jeffrey , Rivera-Hernández Robert , Gómez-Torres Luisa , Zafra-Mejía Carlos
Published: August 2019

La fuente de agua para abastecimiento proveniente del páramo se caracteriza por su alto contenido de color y baja turbiedad, lo que representa un inconveniente por considerar en la mayoría de plantas potabilizadoras. Internacionalmente se han realizado estudios al respecto, pero en general, las soluciones que se plantearon fueron costosas y no se adaptaron totalmente a este tipo de fuentes colombianas (país con escasas investigaciones). El propósito de este trabajo fue la evaluación de FeCl3 como coagulante primario y PAC (Policloruro de aluminio) como auxiliar a escala de laboratorio para la potabilización de agua cruda con elevado color y baja turbiedad. Se realizó el ensayo de jarras con FeCl3, PAC, FeCl3 + PAC como ayudante de coagulación, y FeCl3 + PAC como ayudante de floculación. Los parámetros evaluados fueron pH, color y turbiedad, antes y después de los tratamientos; con un rango de dosis para FeCl3 entre 36-42 mg/L y para PAC entre 0,2-0,5 mg/L. Los resultados revelaron que en términos de eliminación de color la combinación FeCl3 + PAC como ayudante de coagulación presentó la mayor eficiencia entre los tratamientos estudiados (86,9 %), mientras que para remoción de turbiedad el rendimiento alcanzó 80,2 %. De igual manera, se demostró que dicha alternativa representó un ahorro en costos, si se compara con PAC como único coagulante (entre 25,5-34,2 %), dependiendo del caudal tratado. En cuanto al cumplimiento de la normatividad vigente colombiana, se cumplió con los valores máximos permisibles (Color = 15 UPC, Turbiedad = 2 UNT), con excepción del pH que debió estar entre 6,5-9,0, y que debió ser estabilizado antes de enviar el agua tratada por la red de distribución.

Published: August 2019

La enseñanza del uso sostenible del agua es un elemento clave para el cuidado del medio ambiente. Esto es cierto en todos los niveles de formación, pero cobra vital importancia en la educación básica, puesto que permite en los estudiantes la creación de hábitos adecuados y consciencia ambiental desde una edad temprana. Considerando esta situación, los docentes de ciencias naturales deben centrar sus esfuerzos en emplear estrategias para la enseñanza de esta temática, siendo una con gran potencial el uso de videojuegos, gracias entonces al interés que esta tecnología suele despertar en esa población. El objeto de este trabajo es la descripción de un videojuego para la enseñanza del cuidado del agua, el cual se diseñó en formato de sandbox 3D y con una estética similar a la del popular Minecraft. Se presenta su validación en un entorno educativo real en el que participaron 65 estudiantes de cuarto grado, de una institución educativa en el municipio de Bello, Colombia. Los resultados obtenidos permitieron determinar de forma cualitativa, pero también cuantitativa y con significancia estadística, que dicha estrategia propició una mayor apropiación en sí de los estudiantes, al tiempo que generó actitudes positivas hacía la estrategia y hacia la temática abordada.
Simple theoretical proposal of the dependence of the deGennes extrapolation parameter with the surface temperature of a superconducting sample
Authors: Barba-Ortega José José , González Jesús D. , Rincón-Joya Miryam
Published: August 2019

The Time-dependent Ginzburg–Landau model (TDGLM) is a robust tool widely used to analyze the magnetization of the single-vortex state of a mesoscopic superconducting sample in presence of a magnetic field. The algorithm implemented in this work is applied to a square geometry surrounded by diﬀerent kinds of materials simulated by deGennes extrapolation length . The inside of the sample remains at constant temperature , while its boundary remains at temperature . This temperature variation in the sample can be generated by a continuous laser wave injected into all the internal points, except for a thin surface layer in the boundary of the material. We found that the b value at , which mimics the magnetization curve for a corresponding , presents a linear dependence with the temperature. Therefore, although within the domain of validity TDGLM the parameter  is to be considered temperature-independent in the vicinity of the bulk critical temperature and that  depends on the density of states near the surface, we propose a simple dependence of using a TDGLM.

El desarrollo de Internet y las comunicaciones digitales generó uno de los mas grandes revolcones en la forma cómo se desarrolla la mayoría de las actividades en qué interviene el ser humano: y la divulgación científica no ha sido la excepción. La publicación en línea no sólo ha obligado a modificar los procesos editoriales de las revistas científicas, también ha obligado a replantear la función principal de estas. Mientras que hace algunos años las revistas científicas eran determinantes para decidir los contenidos que estarían disponibles para consulta por la comunidad científica, en la actualidad, el autor tiene la posibilidad de publicar sus documentos de forma autónoma y ponerlo a discusión en redes sociales académicas o blogs personales. En este escenario, las revistas científicas tienen la función principal de ser garantes de la calidad técnica, científica y del contenido de los trabajos que en ella se publican, y ofrecer a los autores la confianza de que su trabajo será evaluado de formar rigurosa y transparente.
Dairy supply chain in Southern Brazil: barriers to competitiveness
Authors: Beber Caetano Luiz , Carpio Andres Fabricio Ruales , Almadani Mohamad Isam , Theuvsen Ludwig
Published: August 2019

The Brazilian dairy industry is still in its infancy, especially in regards to competitiveness on foreign markets. Therefore, it is facing difficult challenges to upgrade in terms of professionalisation, productivity and technological improvements, but also to avoid exclusion of small-scale farms. This study identifies the main factors affecting the competitiveness and slowing the modernisation of the supply chain in one of the most promising and dynamic dairy production areas in the world – the mesoregion ‘Grande Fronteira do Mercosul’ in Southern Brazil. The analysis is based on the perceptions of supply chain leaders about the challenges to improving the industry’s competitiveness. The paper also presents various strategies already implemented by some actors to overcome such barriers to competitiveness. The empirical results have manifold implications. One of which is that the problems and strategies must be the target of managers and authorities in a sustainable common project of development to the benefit of the whole dairy supply chain.
Imaginários religiosos e políticos na América Latina
Authors: Oro Ari Pedro
Published: August 2019

Este texto apresenta uma série de idéias propostas pela equipe de pesquisadores do GRIPAL (Groupe de Recherches sur les Imaginaires Politiques en Amérique Latine), da Universidade de Quebec, em Montreal, acerca das relações entre os imaginários religiosos e políticos na América Latina. Tais formulações resultam de pesquisas de campo realizadas na Argentina, Brasil, Chile, México e Venezuela. A amostra é composta de dois terços de indivíduos das camadas desfavorecidas, pertencentes aos segmentos católico e evangélico (predominantemente pentecostais e neo-pentecostais), e de um terço de estudantes universitários. O texto analisa, em primeiro lugar, a impregnação do imaginário religioso nesses segmentos religiosos e sociais, em seguida, a presença do imaginário político e, por fim, analisa as relações existentes entre ambos os imaginários. No texto, é estabelecido um diálogo entre as formulações do mencionado grupo canadense e aquelas propostas por alguns autores latino-americanos acerca do mesmo objeto.
Repensando fronteiras sociológicas e estratégias de atuação
Authors: Duarte Tatiane dos Santos
Published: August 2019

Este paper trata da análise de aspectos do processo de construção da carreira religiosa de uma pastora envolvida em disputas por um espaço legítimo no campo evangélico através do re-conhecimento pela alta hierarquia evangélica local de sua “habilidade específica” como “porta-voz autorizada” de um novo Ministério. Diante deste quadro de referência, a etnografia é a opção metodológica que permite articular o local com os domínios mais amplos da vida social, como por exemplo, a atuação de evangélicos nos meandros da “grande política”.
apariciones de la Virgen. El fenómeno de las apariciones de la virgen en Salta
Authors: Ameigeiras Aldo , Suarez Ana Lourdes
Published: August 2019

El fenómeno de las apariciones de la virgen en Salta, al igual que cientos que actualmente tienen lugar en el mundo, se abre espacio a través de la conjunción de diversas prácticas: peregrinación, devoción mariana y sanación, conformando un campo religioso de creciente relevancia en América Latina. En este trabajo presentamos el fenómeno en términos de las lógicas y motivaciones de sus principales actores y de las tensiones y conflictos que lo atraviesan. Nos detenemos principalmente en la discusión de marcos analíticos que ayudan a comprender la complejidad y diversidad de significados y acciones que estructuran este tipo de campos sociales. A partir del mismo abordamos algunos interrogantes que nuestro caso suscita. Destacamos los aspectos que marcan continuidades con el patrón histórico de apariciones, y aquellos que lo singularizan: el fuerte protagonismo de la vidente, la oración de intercesión, el rol de la organización, y su particular misión evangelizadora.
Estéticas da existência em fluxo
Authors: Bizerril José
Published: August 2019

Análises macrossociológicas contemporâneas associaram as configurações sociais do capitalismo globalizado a certa forma de sujeito corporificado, tributária das biotecnologias e afinada com a lógica de consumo. Contudo, etnografias de realidades subculturais específicas podem ilustrar formas alternativas de subjetivação corporificada. Fora da China e das comunidades diaspóricas de imigrantes, sujeitos urbanos pertencentes a contextos multiculturais globalizados têm se aproximado do universo das práticas e do modo de vida taoista. Reflito neste artigo sobre o potencial desta tradição, ressignificada em situações de transplante cultural, para fazer frente aos dilemas decorrentes da instabilidade das condições de vida e de produção de sentido característicos da experiência dos segmentos sociais mais diretamente afetados pelas transformações socioculturais do mundo contemporâneo. Por meio de uma verdadeira estética da existência, esta tradição proporia uma rota alternativa à produção corporificada de si oferecida pelo consumo e pelas biotecnologias. Analiso esta situação a partir de um caso brasileiro.
Magia e cultura colonial brasileira
Authors: Santos Eurico Antonio González Cursino dos
Published: August 2019

O texto procura construir as bases metodológicas para uma interpretação “macro” da história religiosa brasileira, bem como das relações entre os processos religiosos e os políticos quando da formação dos fundamentos da cultura brasileira atual. A partir de um quadro teórico geral weberiano, que enfatiza as características racionais da ação individual, a análise indicou a importância dos conceitos de escravidão e de magia para a adequada interpretação de nossa história religiosa. A escravidão apareceu como a realidade última, inafastável, e a magia, como o instrumento cognitivo utilizado para interpretá-la.
Notas sobre las esferas diferenciadas de valor en Max Weber
Authors: Esquivel Juan Cruz
Published: August 2019

El trabajo examina algunas cuestiones que definen la metodología weberiana para la comprensión del mundo moderno; principalmente, la caracterización de las esferas de valor como órdenes autónomos en tanto sus fundamentos emanan de su propia legalidad interna. Desde esta perspectiva de análisis, intenta desentrañar los fundamentos exclusivamente religiosos presentes en la pretensión de las autoridades de la Iglesia Católica argentina de renunciar a los aportes económicos provenientes del Estado Nacional. Por detrás de tal propósito, es posible vislumbrar una confrontación entre las esferas en pugna por instalar sus valores y cosmovisiones en la sociedad. De esta forma, se podrá evaluar el alcance del esquema interpretativo propuesto por Weber en cuanto a su aplicabilidad a una situación determinada del mundo actual.
SOS Mulher
Authors: Machado Maria das Dores Campos
Published: August 2019

Trata-se de uma análise da mídia pentecostal com o objetivo de verificar a “imagem” da mulher transmitida por esses grupos religiosos: seus papeis, comportamentos e relações na família, na comunidade religiosa e na sociedade mais ampla. A inclusão de temas como o aborto, planejamento familiar, sexualidade, participação feminina na política e no mercado de trabalho sugere que, seja em atendimento as demandas das leitoras, seja pela incorporação de mulheres no seu corpo editorial, os dois grupos tentam se alinhar com os processos sociais que afetam a identidade feminina. As possibilidades da construção de uma imagem mais positiva e afirmativa das mulheres, bem como os limites dessa redefinição da identidade do gênero feminino no universo pentecostal serão apontados nas conclusões dessa comunicação.
Algumas técnicas corporais na Renovação Carismática Católica
Authors: Raymundo Heraldo Maués
Published: August 2019

Este artigo trata de algumas técnicas corporais na Renovação Carismática Católica, partindo clássica definição de Marcel Mauss a respeito dessas técnicas: “as maneiras como os homens, sociedade por sociedade e de maneira tradicional, sabem servir-se de seus corpos” (“Les façons dont les hommes, societé par societé, d’une façon traditionnelle, savent se servir de leur corps”). O trabalho de campo foi feito em Belém, Pará, Brasil, em quatro paróquias católicas. As técnicas descritas e interpretadas foram, entre outras: o toque corporal, a imposição de mãos, a dança, a glossolalia (orar em línguas) e o repouso no Espírito. Foi feita uma comparação com as técnicas corporais utilizadas numa espécie de culto xamanístico muito popular entre habitantes rurais (“caboclos”) da Amazônia Brasileira chamada “pajelança cabocla”. Embora muitas das técnicas sejam as mesmas, enfatiza-se que a diferença reside na maneira pela qual as pessas as concebem, isto é, em seus significados diversos.
Violência e sagrado
Authors: Freitas Eliane Tânia Martins de
Published: August 2019

Este artigo apresenta um exame preliminar de dois cultos religiosos populares que ocorrem atualmente no Nordeste do Brasil. Em dois cemitérios, no Rio Grande do Norte, o cangaceiro Jararaca e o ladrão homicida Baracho (espécie de ‘serial killer’, conhecido como ‘matador de motoristas’), são objetos de devoção religiosa por parte de crentes que afirmam ter alcançado milagres por seu intermédio ou que acreditam que virão a alcançá-los por meio de promessas que então, à beira de seus túmulos, não hesitam em fazer. A fé em seus milagres convive com a memória dos feitos dos bandidos que foram em vida, narrados com um misto de admiração e reprovação moral. O tradicional modelo do bandido social, que rouba para dar aos pobres, vem então em seu socorro, de modo a permitir uma continuidade entre o passado criminoso e o presente ‘santificado’. Dentre os fatores centrais nesse processo de ‘santificação’ do bandido, segundo o discurso dos entrevistados, estão a morte violenta e o sofrimento físico e moral a ela associados. O quadro esboçado aqui mostra-nos que se trata de santos muito especiais, isto é, santos precários, posto que sua santidade é objeto de constante controvérsia e contestação mesmo por aqueles que acreditam em seu poder de operar milagres. E parece ser mesmo isso o que os torna tão interessantes, mesmo do ponto de vista dos seus adeptos.
