Impacto de los sólidos suspendidos totales sobre la obstrucción en emisores de riego localizado de alta frecuencia
Authors: Sánchez Luis D. , Viáfara Christian A.
Published: April 2019

Este estudio a escala piloto evaluó el impacto de los sólidos suspendidos totales, SST, sobre la obstrucción en emisores de riego localizado de alta frecuencia, RLAF, empleando como tratamiento para mejorar la calidad de agua un filtro de grava de flujo ascendente con mantas sintéticas (FGAC Manta). El efluente de dicho tratamiento alimentó cuatro tipos de sistemas RLAF: Lyn, Autocompensado, Microjet y Cinta de riego, para evaluar la incidencia del aporte de los SST sobre cada uno de ellos. Para ello se evaluó el riesgo de obturación, el coeficiente de uniformidad (Cu), la concentración de sólidos depositados en las paredes de los conductos y el tamaño de partícula que ingresó a los RLAF. Los resultados mostraron que cuanto mayor fue la concentración de SST, menor fue el tiempo de riego alcanzado por las tecnologías RLAF. La relación de los SST aportados a los RLAF con el tamaño de partícula que ingresó a los conductos y emisores presentó partículas hasta de 129 micras, que contribuyen a la obturación de los emisores. El régimen laminar contribuye a la deposición de sólidos en los conductos de los emisores de las tecnologías RLAF afectando el Cu.

Published: April 2019

ResumenLos estudios de planificación del transporte urbano adelantados en Colombia muy pocas veces incluyen la modelación de los viajes peatonales, en especial para establecer la probabilidad de caminar. Este artículo reporta los resultados de la investigación para analizar la elección del modo caminata de las personas en un contexto urbano con base en datos de encuestas domiciliarias. El objetivo principal de la investigación es demostrar cómo la información proveniente de encuestas domiciliarias sirve para modelar la probabilidad de caminar en una ciudad. Son utilizados datos de encuestas realizadas en dos ciudades colombianas (Barrancabermeja y Cajicá) con los cuales se estiman modelos de elección. Los resultados del estudio indican que la probabilidad de caminar disminuye a medida que aumentan los valores de atributos tales como tiempo de viaje, número de autos en la familia e ingreso personal, y aumenta cuando se trata de personas jóvenes y grupos familiares de mayor tamaño.

Análisis de sensibilidad de los resultados del modelo de gestión SUE (Sistema Universitario Estatal) basado en el análisis envolvente de datos
Authors: Amariles Juan M. , Soto-Mejía José A.
Published: April 2019

El Sistema Universitario Estatal (SUE) colombiano utiliza un modelo matemático para evaluar las universidades públicas “rankeandolas” según su desempeño. Sin embargo, se hace necesario proponer otro(s) enfoque(s) pues los resultados han generado inconformidades. Este trabajo propuso un modelo alternativo (Soto & Arenas, 2005) basado en Análisis Envolvente de Datos (DEA) que permite calcular el desempeño de las universidades del SUE.El modelo DEA convencional no incluye directamente la posibilidad de evaluar la sensibilidad de la eficiencia a variaciones en la información. Tener una medida de hasta qué punto un conjunto de Unidades de Decisión (Decision Making Unit-DMU) conserva su eficiencia debido a estas variaciones es fundamental para conocer la robustez de los resultados.Este artículo propone utilizar el enfoque de Análisis de sensibilidad de modelos DEA para cambios simultáneos en la información, desarrollado por (Seiford & Zhu, 1998), para medir la sensibilidad de los resultados del modelo SUE basado en DEA. Inicialmente se expondrán algunas de las razones para analizar la sensibilidad del modelo. Luego se presentará el enfoque escogido describiendo su metodología y se aplicará al modelo SUE basado en DEA. Finalmente se presentarán sus resultados y conclusiones

Published: April 2019

1. La necesidad actualmente difundida de competir a través de la diferenciación del mercado, ocasionada por la globalización y liberalización del comercio, ha puesto a la innovación tecnológica y a su administración efectiva en el centro de las estrategias empresariales exitosas.2. Aún más, hay un número creciente de señales que indican que el crecimiento y la sostenibilidad del sistema económico global, incluyendo el libre comercio, está amenazado por desigualdades cada vez mayores, la explosión demográfica y el desequilibrio en el poder mundial.3. La preservación de la calidad de vida en los países ricos, la cual depende del consumo de una mayor proporción de los recursos y la energía mundial, convierte a estos países en rehenes del crecimiento continuo del sistema económico global y la liberación del comercio.4. La única solución sostenible al planteamiento anterior es el crecimiento económico masivo y acelerado de los países tercermundistas sobre la base de productos y servicios ambientalmente seguros, que satisfagan las aspiraciones mundiales de consumo.5. Esta solución clama por una nueva revolución industrial basada en tecnologías radicalmente nuevas, la cual representa una oportunidad para los países en desarrollo, de defender un desarrollo industrial acelerado y equilibrar la distribución de la riqueza y el poder mundial.6. Para poder aprovechar esta oportunidad y lograr el desarrollo acelerado , las empresas de los países en desarrollo deberán ser capaces de administrar efectivamente las innovaciones tecnológicas estratégicas requeridas para generar las nuevas tecnologías, productos y servicios que caracterizan a la nueva revolución industrial.7. Algunas personas podrían interpretar las señales actuales de manera diferente y plantear un escenario futuro en el cual prevalece la evolución de los patrones actuates. De cualquier forma, la capacidad de administrar efectivamente las innovaciones tecnológicas, está llamada a desempeñar un papel central.8. Las agencias especializadas de las Naciones Unidas son por consiguiente las indicadas, para ayudar a los países en desarrollo en la aceleración de este proceso, a través de nuevas herramientas y servicios adecuados.
Influencia de la Localización del Almidón Nativo de Yuca en el Canal de Sedimentación sobre la Calidad del Almidón Agrio
Authors: Tischer Irene , Moreno Martín
Published: April 2019

El proceso productivo del almidón de yuca realizado artesanalmente en el Norte del Departamento del Cauca, incluye una etapa de sedimentación que actualmente se lleva a cabo en canales. Entre los procesadores de yuca de la región existe la opinión, que del inicio del canal se obtiene almidón agrio con un poder de expansión más alto, y por lo tanto se podría vender a un mejor precio. En la presente investigación se analiza si existe una estratificación de calidades de acuerdo a la posición del almidón en el canal. Se evaluaron dos estrategias de recoger el almidón de los canales, a lo largo o perpendicular al canal. Los resultados obtenidos son negativos. Ninguna de las estrategias permite una estratificación de calidades tan significante para que se logre obtener almidones que respondan a las exigencias de los diferentes mercados. Si se busca una calidad homogénea, se recomienda recoger el almidón perpendicular al canal.

Published: April 2019

O artigo a seguir trata das principais implicações da atuação do Supremo Tribunal Federal no reconhecimento de direitos das pessoas LGBT, principalmente trans (transgêneras, travestis e transexuais). Desta forma, além de estabelecer um panorama acerca do que significa o neoconstitucionalismo e as discussões dogmáticas que engendra, debruça-se sobre a Ação Direta de Inconstitucionalidade nº 4.275 proposta pelo Ministério Público Federal, que reconheceu a autodeterminação das pessoas trans para alteração no nome social, sem que haja condicionamento à autorização judicial ou cirurgia de transgenitalização. Pontua que não visa estabelecer um novo rol, que amplia o previsto na Constituição Federal, mas sim, por meio de princípios e fundamentos como isonomia e dignidade da pessoa humana e pela hermenêutica constitucional erigida pós-redemocratização no Brasil, assegurar que as garantias da Carta Magna sejam observadas também na vida da população que compõe essa minoria social.

Highly proton conductive membranes based on carboxylated cellulose nanofibres and their performance in proton exchange membrane fuel cells
Authors: Guccini Valentina , Carlson Annika , Yu Shun , Lindbergh Göran , Wreland Lindström Rakel , Salazar-Alvarez Germán
Published: April 2019

The performance of thin carboxylated cellulose nanofiber-based (CNF) membranes as proton exchange membranes in fuel cells has been measured in-situ as a function of CNF surface charge density (600 and 1550 µmol g-1), counterion (H+or Na+), membrane thickness and fuel cell relative humidity (RH 55 to 95 %). The structural evolution of the membranes as a function of RH as measured by Small Angle X-ray scattering shows that water channels are formed only above 75 % RH. The amount of absorbed water was shown to depend on the membrane surface charge and counter ions (Na+or H+). The high affinity of CNF for water and the high aspect ratio of the nanofibers, together with a well-defined and homogenous membrane structure, ensures a proton conductivity exceeding 1 mS cm-1at 30 °C between 65 and 95 % RH. This is two orders of magnitude larger than previously reported values for cellulose materials and only one order of magnitude lower than Nafion 212. Moreover, the CNF membranes are characterized by a lower hydrogen crossover than Nafion, despite being ≈ 30 % thinner. Thanks to their environmental compatibility and promising fuel cell performance the CNF membranes should be considered for new generation proton exchange membrane fuel cells.

Published: April 2019

Traditional natural products discovery workflows implying a combination of different targeting strategies including structure- and/or bioactivity-based approaches, afford no information about new compound structure until late in the discovery pipeline. By integrating a MS/MS prediction module and a collaborative library of (bio)chemical transformations, we have developed a new platform, coined MetWork, that is able of anticipating the structural identity of metabolites starting from any identified compound. In our quest to discover new monoterpene indole alkaloids, we demonstrate the utility of the MetWork platform by anticipating the structures of five previously undescribed sarpagine-like N-oxide alkaloids that have been targeted and isolated from the leaves of Alstonia balansae using a molecular networking-based dereplication strategy fueled by computer-generated annotations. This study constitutes the first example of a natural product discovery workflow, termed CANPA, in which the targeted structures were initially generated and therefore anticipated by a computer prior to their isolation.
Applied Process Simulation-Driven Oil and Gas Separation Plant Optimization using Surrogate Modeling and Evolutionary Algorithms
Authors: Andreasen Anders
Published: April 2019

In this article the optimization of a realistic oil and gas separation plant has been studied. Two different fluids are investigated and compared in terms of the optimization potential. Using Design of Computer Experiment (DACE) via Latin Hypercube Sampling (LHS) and rigorous process simulations, surrogate models using Kriging have been established for selected model responses. The surrogate models are used in combination with a variety of different evolutionary algorithms for optimizing the operating profit, mainly by maximizing the recoverable oil production. A total of 10 variables representing pressure and temperature various key places in the separation plant are optimized to maximize the operational profit. The optimization is bounded in the variables and a constraint function is included to ensure that the optimal solution allows export of oil with an RVP < 12 psia. The main finding is that, while a high pressure is preferred in the first separation stage, apparently a single optimal setting for the pressure in downstream separators does not appear to exist. In the second stage separator apparently two different, yet equally optimal, settings are revealed. In the third and final separation stage a correlation between the separator pressure and the applied inlet temperature exists, where different combinations of pressure and temperature yields equally optimal results.

Canadian Narcotics Policy: A Relic of Settler Colonialism
Authors: Mytrunec Michael
Published: April 2019

In this paper, I examine the formation and enforcement of Canadian narcotics policy through the lens of settler colonialism. By examining the rationale for Canadian policies towards opium, cannabis, and quat, I challenge the notion that public health and safety played a material role the formation of Canadian narcotics policy. Rather, racialized targeting of minority groups was a key driver for creating laws to prohibit certain narcotics and incidentally target undesirable subcultures. Evidence that punitive and enforcement-oriented strategies for controlling narcotic  drugs are ineffective have frequently been met by the continuation of these very strategies, further undermining the stated purposes for enacting strict drug laws. Language of “law and order” and the propensity to crack down on drug users, coupled with racial profiling and police biases, has continued the disproportionate racial impacts of drug laws, and the successes of narcotics policy in entrenching the status quo have outweighed their failures in reducing drug consumption. I conclude that, as it exists currently, Canadian narcotics policy is inseparable from Canada’s past as a settled, colonial nation-state.

Published: April 2019

El prurito crónico se define como una sensación no placentera de la piel que induce el rascado y que dura más de seis semanas. Este síntoma puede ser la manifestación de una enfermedad cutánea o sistémica y compromete la calidad de vida de los pacientes, alterando de forma consistente el sueño y las actividades diarias. La fisiopatología es compleja e incluye múltiples mediadores y sus respectivos receptores, que a través de diferentes vías de señalización llevan información por las fibras nerviosas tipo C hacia el tálamo, desde donde se distribuye a diversas zonas de la corteza cerebral. La comprensión de estos mecanismos ha permitido identificar posibles blancos terapéuticos y el desarrollo de moléculas cada vez más efectivas y seguras para los pacientes. La presente revisión pretende dar una visión acerca del manejo diagnóstico y terapéutico de los pacientes con prurito crónico.

Philanthropy can be learned: A qualitative study of student experiences in experiential philanthropy courses
Authors: Li Huafang
Published: April 2019

Experiential philanthropy is an innovative service-learning pedagogy that allows students to study social problems and nonprofit organizations and then make decisions about investing funds into nonprofits working to address these problems. Although prior research has shown that instructors’ use of experiential philanthropy is positively associated with a number of student learning outcomes, few studies have employed in-depth qualitative methods to assess the effectiveness of experiential philanthropy—especially from the perspective of students. Therefore, in this study, we utilize computer-assisted technologies to mine data from students (n=973) concerning their perceptions about participating in an experiential philanthropy course. Overall, our results show that similar to the results of prior research, students do believe that experiential philanthropy enhances their learning as well as their willingness to contribute to their community. However, for some students, engaging in experiential philanthropy is less likely to enhance their desire to contribute monetarily to nonprofit organizations and more likely to enhance their desire to contribute in the form of voluntary action.

Adjective forms and functions in British English child-directed speech
Authors: Davies Catherine , Lingwood Jamie , Arunachalam Sudha
Published: April 2019

Adjectives are essential for describing and differentiating concepts. However, they have a protracted development relative to other word classes. Here we measure three and four year-olds’ exposure to adjectives across a range of interactive and socioeconomic contexts to: i) measure the syntactic, semantic, and pragmatic variability of adjectives in child-directed speech (CDS); and ii) investigate how features of the input might scaffold adjective acquisition. In our novel corpus of UK English, adjectives occurred more frequently in prenominal than in postnominal (predicative) syntactic frames, though postnominal frames were more frequent for less familiar adjectives. They occurred much more frequently with a descriptive than a contrastive function, especially for less familiar adjectives. Our findings present a partial mismatch between the forms of adjectives found in real-world CDS and those forms that have been shown to be more useful for learning. We discuss implications for models of adjective acquisition and for clinical practice.
Lessons learned: The longitudinal effects of Austria’s labor market integration policies on Bosnian refugees
Authors: Hussain Isra Syed
Published: April 2019

The response to the recent influx of refugees in Europe indicates a need to reevaluate systems of reception and integration in a global society that is marred by increased xenophobia and nationalist rhetoric. Nearly three decades ago, the Austrian government deployed special accommodations to handle a similarly sized influx of refugees entering Europe, individuals and families who were fleeing ethnic cleansing from the Bosnian War. These accommodations, and their eventual economic integration components, provide longitudinal data that indicates a system that allowed employment rates of Bosnian refugees to match the rate of host country populations within a generation. Through thematic analysis of an extensive literature review and field consultations in Vienna, this research will investigate what lessons the global community can learn from Austria’s treatment of Bosnians refugees, and whether these lessons can contribute to improved procedures for integrating refugees into host societies. Preliminary results indicate the role of social capital, civil society, and religion as factors of labor market integration, while also acknowledging rates of underemployment and stagnation in the asylum process as deterrents to positive relationship formation between host societies and refugee populations. The culmination of this year-long project will be a series of recommendations on how local and national actors can enact services that will benefit the longer-term goals of both refugee populations and host societies.
Awareness of oral cancer and potentially malignant oral disorder among final year medical and dental undergraduate students of Chitwan Medical College, Nepal
Authors: Subedi Sushil , Shrestha Bijayata
Published: April 2019

Background: Oral Cancer (OCA) is a common malignancy in South East Asia and the burden of the disease is increasing. OCA is usually preceded by Potentially Malignant Oral Disorder (PMOD). The early detection of these diseases may limit the high mortality and morbidity. The objectives of this study were to assess the awareness of burden, associated risk fac­tors, early detection and prognosis of OCA and OPMD among final year medical and dental students..

Methods: This cross sectional study was conducted among final year Medical and Dental undergraduate students of Chitwan Medical College, Nepal in April 2017 using a pre tested self-administered questionnaires. All the final year students present at their respective classes (Dental= 50 and Medical=75 students) responded to the questionnaires after giving informed consent. Data entered in SPPS 20 software was analyzed using Pearson Chi Square test and Fisher exact test.

Results: Dental students had better awareness concerning PMOD. Yet, the dental students did not differ significantly from their medical coun­terpart in most of the responses related to OCA. Surprisingly, more Dental students had misconception that OCA is not preventable and early detec­tion is difficult. Few of both groups were confident in having sufficient knowledge in OCA prevention and detection. Only 18.6% of Medical stu­dents had examined PMOD and few students of both groups had exam­ined OCA.

Conclusions: This study revealed the deficient aspect in the knowledge concerning OCA and OPMD among Medical and Dental students indicat­ing the need to emphasize on these aspects of medical education.
