Cuando creces, yo crezco contigo”: La configuración de áreas de protección ambiental y de subjetividades en el Humedal de Córdoba y la vereda El Verjón Bajo

La configuración de lugares como áreas de protección ambiental puede ser vista como un proceso técnico y objetivo, en el que se crean políticas públicas que definen prácticas adecuadas e inadecuadas en el lugar. Pero esta configuración es un proceso histórico y negociado. Este se construye en contante diálogo entre diferentes actores que se preocupan por definir qué es la naturaleza y el cuidado ambiental, y las percepciones que individuos que habitan en o cerca a estos lugares construyen en su diario vivir. Es así como la configuración socioambiental de lugares como áreas de protección ocurre por transformaciones en la forma de percibir un lugar, la relaciones con este y sobre todo, prácticas y relaciones que se traducen en formas de negociar nociones de naturaleza y cuidado ambiental. Esta negociación tiene grandes implicaciones en los individuos, particularmente en su subjetividad. Es decir, en hechos como la forma de nombrarlo, caminarlo, observar las especies, iniciar proyectos de agricultura orgánica, cambiar prácticas productivas, el cerramiento de zonas para proteger las fuentes de agua o zonas de vegetación. También sobre su subjetividad, la manera como se sienten frente al lugar, como juzgan sus acciones y las de otros y cómo construyen objetivos personales con respecto a la idea de cuidado ambiental.The process of recognizing a place as a natural protected area can be seen as a technical one. In which objective criteria is used to define its characteristics and the appropriate or inappropriate practices in it. But this configuration is a historical and negotiated process. Understanding a place as a natural protected area is a constant dialogue between multiple actors, those who are willing to define nature and environmental care or conservation and the people that live in or near these places, who in their daily lives, build upon these concepts. This social and environmental process occurs in the transformation of perception of places, the relation people build with them and specific practices and relations that are ways of negotiating notions of nature and environmental care. These have great impact on individuals, especially on their subjectivity. Implications that can be seen in facts such as the changes of how people name place, walk on them, observe the species, start agricultural projects, and change their production practices, between others. But mainly on a subjective level, the way they feel over the place, they judge themselves and other´s actions and how they create personal goals over the idea of environmental care

LEUCOENCEFALOPATÍA MULTIFOCAL PROGRESIVA SECUNDARIA A VIH

Una de las complicaciones más temidas de la infección por el virus de la inmunodeficiencia humana (VIH) es la leucoencefalopatía multifocal progresiva (LMP), la cual se debe a la activación del virus JC en la sustancia blanca del cerebro, lo cual produce muerte de los oligodendrocitos, las células encargadas de la síntesis de sustancia blanca a nivel del sistema nervioso central. Se presenta el caso de una paciente de 37 años con el diagnóstico de infección por VIH hace 15 años, la cual ingresó al servicio de emergencia con un cuadro compatible con deterioro del nivel de conciencia, síndrome confusional agudo; fue trasladada al servicio de Infectología donde la resonancia magnética practicada demostró lesiones compatibles con LMP

Development of an estimation model for the evaluation of the energy requirement of dilute acid pretreatments of biomass

This study aims to develop a mathematical model to evaluate the energy required by pretreatment processes used in the production of second generation ethanol. A dilute acid pretreatment process reported by National Renewable Energy Laboratory (NREL) was selected as an example for the model's development. The energy demand of the pretreatment process was evaluated by considering the change of internal energy of the substances, the reaction energy, the heat lost and the work done to/by the system based on a number of simplifying assumptions. Sensitivity analyses were performed on the solid loading rate, temperature, acid concentration and water evaporation rate. The results from the sensitivity analyses established that the solids loading rate had the most significant impact on the energy demand. The model was then verified with data from the NREL benchmark process. Application of this model on other dilute acid pretreatment processes reported in the literature illustrated that although similar sugar yields were reported by several studies, the energy required by the different pretreatments varied significantly

Novel Variant in the CNNM2 Gene Associated with Dominant Hypomagnesemia

The maintenance of magnesium (Mg2+) homeostasis is essential for human life. The Cystathionine-beta-synthase (CBS)-pair domain divalent metal cation transport mediators (CNNMs) have been described to be involved in maintaining Mg2+ homeostasis. Among these CNNMs, CNNM2 is expressed in the basolateral membrane of the kidney tubules where it is involved in Mg2+ reabsorption. A total of four patients, two of them with a suspected disorder of calcium metabolism, and two patients with a clinical diagnosis of primary tubulopathy were screened for mutations by Next-Generation Sequencing (NGS). We found one novel likely pathogenic variant in the heterozygous state (c.2384C>A; p.(Ser795*)) in theCNNM2gene in a family with a suspected disorder of calcium metabolism. In this family, hypomagnesemia was indirectly discovered. Moreover, we observed three novel variants of uncertain significance in heterozygous state in the other three patients (c.557G>C; p.(Ser186Thr), c.778A>T; p.(Ile260Phe), and c.1003G>A; p.(Asp335Asn)). Our study shows the utility of Next-Generation Sequencing in unravelling the genetic origin of rare diseases. In clinical practice, serum Mg2+ should be determined in calcium and PTH-related disorders.This study was supported by three grants from the Department of Health (2017111014, 2018111097 and 2019111052) and one grant from the Department of Education (IT1281-19) of the Basque Government.

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis
