Procesos comunicativos en la medicina ancestral andina, cantón Otavalo, comunidad de Kotama
Los procesos comunicativos son importantes en la perspectiva de que pueden llegar a
determinar las relaciones socio-culturales existentes en los distintos sistemas políticos y
económicos. Si partimos del reconocimiento que en estos sistemas hay temáticas
significativas, necesarias para el conocimiento y mejoramiento de las formas de vida, se
puede aseverar que la Medicina Ancestral Andina, en los pueblos del Ecuador, forma
parte de los elementos comunicativos existentes en los procesos sociales.
La medicina ancestral es de vital importancia para la sobrevivencia de la población y
por esto se ha convertido en: una opción que ayuda a las personas y es el complemento
a otro tipo de prácticas medicinales. Por tal motivo, dar a conocer la Medicina Ancestral
es aportar a la revitalización de la historia de los pueblos Andinos y al fortalecimiento
de nuestra identidad, a fin de generar nuevas formas de convivir con la naturaleza, en
interacción con el ser humano, sin destruirla, entendiéndola como el entorno donde es
posible dar y recibir la vida.
En el presente estudio se establecen algunos criterios para entender los procesos
comunicativos dentro de la medicina tradicional andina en la actualidad. Entendemos
que la medicina alopática o medicina convencional tiene un carácter curativo o de
extensión de la vida del ser humano, mientras que la medicina ancestral, a través del
conjunto de todos sus saberes, es aplicada con la finalidad de prevenir y curar
enfermedades, para que tanto el ser humano como la naturaleza mantengan su armoní
Perspectivas de cambio para una adecuada protección social en el Ecuador de los vendedores informales en condición de vulnerabilidad
En el Ecuador, la protección social de las y los vendedores informales ambulantes en condición de vulnerabilidad requiere el resquebrajamiento de los paradigmas actuales en materia de seguridad social y el establecimiento de otros nuevos que se sustenten efectivamente en principios como la universalidad, la igualdad, la solidaridad y la no discriminación, dentro de un grupo de la población que históricamente ha sido marginado y mal visto. La exigibilidad del derecho humano a la seguridad social cuya evolución histórica en materia de políticas públicas es reciente, consagrado en la Constitución y en diferentes instrumentos internacionales se muestra prioritaria y esquiva, así como el establecimiento de modelos y esquemas diferenciados no contributivos que permitan dar cobertura, a las personas más pobres y vulnerables, entre las cuales destacan las y los vendedores informales ambulantes de la tercera edad. Tornándose en la práctica la exigibilidad del derecho humano a la seguridad social un problema de justiciabilidad, pues mientras no se logren establecer los medios e instrumentos jurídicos idóneos para hacer efectivo un derecho ante los tribunales, el mismo no pasa de ser un enunciado de buenas intenciones que se dilatan bajo una errada concepción de los derechos sociales, económicos y culturales. Para lograr la universalización del derecho es indispensable una legislación coherente y progresista que permita que el Estado se haga cargo de una obligación que demanda la Constitución e instrumentos internacionales y que se pretende desvanecer de la mano de teorías que buscan diferenciar entre los derechos humanos de primera y segunda generación o a través de principios mal entendidos como la solidaridad, bajo esquemas contributivos que dejan de lado a quienes no pueden aportar económicamente con el sistema de seguridad social
Analysis of pollutant emissions and fuel consumption, during real driving cycles in different intake temperature scenarios
[EN] Current European vehicle homologation regulations are increasingly restrictive. Recently, World-wide light-duty test cycle (WLTC) and Real driving emissions (RDE) cycles have been introduced as type approval tests for new vehicles. This document studies the effect of intake temperature on pollutant emissions and fuel consumption of a Euro 6 Diesel engine when tested under WLTC and RDE. The tests have been performed by setting the temperature at the outlet of the water charge air cooler (WCAC) at 35 degrees C and 20 degrees C in different tests. To do that, the air-cooler was immersed in a temperature-controlled water bath. This temperature reduction can be produced due to an improvement in the WCAC in the same ambient temperature or also with the same WCAC in case of the ambient temperature is lower. All tests have been carried out in an engine test bench, eliminating the uncertainty involved on the road (driving mode, traffic, ambient temperature, etc.). Once the WLTC and RDE cycles were performed, carbon dioxide (CO2) and pollutant results were analyzed. Nitrogen oxides (NOX) emissions were considerably reduced when the engine intake temperature air was decreased, concretely a 7.1% in RDE and 11.63% in WLTC and the CO2 emissions were also cut down around 1%.Luján, JM.; Climent, H.; Ruiz-Rosales, S.; Redondo-Puelles, F.

RESUMEN: Durante años en el ámbito del desarrollo de software siempre ha sido de preocupación la entrega de nuevas soluciones de una manera ágil y segura, en la búsqueda de una solución a esta necesidad fue surgiendo el término de entrega continua y con el paso del tiempo tomó mucha fuerza hasta hoy en día, que pasó a ser una práctica de desarrollo bastante adoptada en el medio, con la que se busca integrar un conjunto de técnicas con el fin de llevar de manera ágil los cambios en el código de una aplicación para pasar a producción de manera más segura. La Universidad de Antioquia no es ajena a esta necesidad, por ende en el presente trabajo se busca entregar un marco de trabajo que permita implementar metodologías para hacer entregas permanentes de cambios al software, especialmente integración continua y control de los cambios tanto de aplicaciones móviles como web de manera ágil, encontrando que la implementación de dicho proceso asegura la calidad del software a la hora de pasar a producción y la automatización de este proceso. Para esto se implementó un servidor con Jenkins el cual nos permite la integración con todo el conjunto de herramientas necesarias para la implementación de esta práctica de desarrollo y siguiendo el marco de trabajo desarrollado se configuraron 2 aplicaciones para adoptarlas en este proceso de integración continuaABSTRACT: For years in the field of software development has always been of concern the delivery of new solutions in an agile and secure way, in the search for a solution to this need was emerging the term of continuous delivery and over time took much strength until today, which became a development practice quite adopted in the environment, which seeks to integrate a set of techniques in order to quickly implement changes in the code of an application to move to production more safely.
The University of Antioquia is no stranger to this need, therefore, in this work we seek to provide a framework that allows us to implement methodologies to make permanent deliveries of changes to the software, especially continuous integration and control of changes to both mobile and web applications in an agile manner, finding that the implementation of this process ensures the quality of the software when going into production and the automation of this process. For this purpose, a server was implemented with Jenkins which allows us to integrate with all the tools necessary for the implementation of this development practice and following the framework developed, two applications were configured to be adopted in this continuous integration process
Soft Tissue Extramedullary Plasmacytoma
We present the uncommon case of a subcutaneous fascia-based extramedullary plasmacytoma in the leg, which was confirmed by the pathology report and followed up until its remission. We report the differential diagnosis with other more common soft tissue masses. Imaging findings are nonspecific but are important to determine the tumour extension and to plan the biopsy
The human CD53 gene, coding for a four transmembrane domain protein, maps to chromosomal region 1p13
The rat OX44/CD53 protein is the prototypic member of a"novel" family of proteins. These proteins are characterizedby four highly hydrophobic transmembrane domains, twosmall extracellular domains, one of which is extensively N-glycosylated,and both the amino and the carboxy terminus intracytoplasmic.This work has been supported by grants from Fundación Ramón Areces and CICYT (SAL90-0209 and SAL91-0043) to P.A.L. and FIS(92-0889) to S.R.CS
In vitro gas production kinetics and degradability of a diet for growing lambs: effect of fibrolytic enzyme products at different dose levels
The objective of this study was to evaluate the effects of three fibrolytic enzyme products (cellulase (CEL), xylanase (XYL) and a 1:1 mixture of CEL and XYL (MIX)) at three dose levels (0, 1 and 3 lL/0.5 g DM) on the in vitro fermentation of a diet for growing lambs. Bottles were incubated for 96 h at 39 C. A mathematical model was used to estimate the parameters describing the gas production (GP) curve (b, c and L). Dry matter degradability (DMD) and fibre (NDFD and ADFD) degradability were determined at the end of the incubation period. Metabolisable energy (ME) and short chain fatty acids (SCFA) were calculated at 24 h of incubation. The asymptotic GP (parameter b) was affected (p<0.02) by enzyme product and dose level, with a significant linear response (p<0.05). Dose level affected ME and SCFA with a significant linear (p<0.05) and quadratic (p<0.01) response. The interaction between enzyme product and dose level was significant (p<0.05) for cumulative GP up to 72 and 96 h of incubation, pH, ADFD and DMD. The results suggest that application of exogenous cellulases has the potential to alter asymptotic GP and degradability of ADF and DM of a diet for growing lambs, but most of the results depend on the interaction between enzyme product and dose level. Future studies are required to determine the ideal combination between enzyme product and dose level for optimal degradation of ruminant feeds
Rigid polyurethane foams with infused nanoclays: Relationship between cellular structure and thermal conductivity
Producción CientíficaA water blown rigid polyurethane (PU) formulation has been used to manufacture cellular
nanocomposites containing different concentrations of montmorillonite nanoclays. The PU
foams have been produced using a low shear mixing technique for dispersing the nanoclays
and by reactive foaming to generate the cellular structure. A detailed characterization
of the cellular structure has been performed. The effect of the nanoparticles on the
reaction kinetics and the state of intercalation of the nanoparticles in the foams has been
analyzed. The thermal conductivity and extinction coefficient of the different materials has
been measured and the results obtained have been correlated with the materials structure.
A strong reduction of cell size and modifications on cell size distribution, anisotropy ratio
and fraction of material in the struts has been detected when the clays are added. In addition,
a reduction of the thermal conductivity has been observed. Different theoretical models
have been employed to explain thermal conductivity changes in terms of structural
features. It has been found that, in addition to the modifications in the cellular structure,
changes in the extinction coefficient and thermal conductivity of the matrix polymer play
an important role on the final values of the thermal conductivity for these materials.We would like to acknowledge to Mr. Vela and Mr. Ferrer, from BASF Española S.L., for supplying the PU formulation employed in this research.

Inferring the Significance of the Polyamine Metabolism in the Phytopathogenic Bacteria Pseudomonas syringae: A Meta-Analysis Approach
To succeed in plant invasion, phytopathogenic bacteria rely on virulence mechanisms to subvert plant immunity and create favorable conditions for growth. This process requires a precise regulation in the production of important proteins and metabolites. Among them, the family of compounds known as polyamines have attracted considerable attention as they are involved in important cellular processes, but it is not known yet how phytopathogenic bacteria regulate polyamine homeostasis in the plant environment. In the present study, we performed a meta-analysis of publicly available transcriptomic data from experiments conducted on bacteria to begin delving into this topic and better understand the regulation of polyamine metabolism and its links to pathogenicity. We focused our research on Pseudomonas syringae, an important phytopathogen that causes disease in many economically valuable plant species. Our analysis discovered that polyamine synthesis, as well as general gene expression activation and energy production are induced in the early stages of the disease. On the contrary, synthesis of these compounds is inhibited whereas its transport is upregulated later in the process, which correlates with the induction of virulence genes and the metabolism of nitrogen and carboxylic acids. We also found that activation of plant defense mechanisms affects bacterial polyamine synthesis to some extent, which could reduce bacterial cell fitness in the plant environment. Furthermore, data suggest that a proper bacterial response to oxidative conditions requires a decrease in polyamine production. The implications of these findings are discussed.Fil: Solmi, Leandro.
