Determination of blue water footprint in forages crops from irrigation disctrict 017, Comarca Lagunera, Mexico

El objetivo de este trabajo fue la determinación de la huella hídrica azul en los cultivos forrajeros del DR-017 Comarca Lagunera, México. Mediante el uso de indicadores de productividad y eficiencia se desarrollaron modelos matemáticos que permitieron estimar la huella hídrica azul de los cultivos. Los resultados muestran que los forrajes ocuparon 45% de la superficie total agrícola, empleando 94,7% del agua subterránea, generando 33% del Valor Bruto de la Producción agrícola. Los índices de productividad física fueron en promedio 252 L kg-1 (sorgo forrajero 181 L kg-1, avena forrajera 413 L kg- 1, alfalfa L kg-1). El ingreso por m3 empleado fue de US$0,04 m-3 en promedio (maíz forrajero US$ 0,07 m-3, alfalfa US$0,05 m-3). El indicador de eficiencia social mostró que en promedio se generaron 0,048 empleos hm-3 (0,037empleos hm-3 en alfalfa y 0,076 empleos hm-3 en rye grass). Finalmente bajo las mismas condiciones de cultivo, así como de mercado, la cantidad mínima que se requiere producir para tener una operación viable (punto de equilibrio) en promedio fue 39,02 t ha-1. En conclusión, la producción de maíz y sorgo forrajero en la región resultó altamente eficiente y productiva en comparación con los demás cultivos forrajeros lo que se tradujo en una menor huella hídrica azul.The aim of this work was the determination of the blue water footprint in forage crops from DR-017 “Comarca Lagunera", México.

Shoulder exoskeleton for rehabilitation actuated with shape memory alloy

Proceedings of RoboCity16: Robots for citizens: Open Conference on Future Trends in Robotics, May 2016This paper presen ts the preliminary design of a rehabilitation exoskele ton for the shoulder joint with three degrees of freedom (DOF), actuated with Shape Memory Alloy (SMA) based actuators. Due to the actuation system, the proposed exoskeleton presents a light weight , low noise and everything in a simple design structure. The number of actuators and the preliminary designed was calculated after a biomechanical simulation of the human body with a specific cat egory of patients.The research leading to these results has received funding from the RoboHealth (DPI2013-47944-C4-3-R) spanish research project and the from the RoboCity2030-III-CM project (Robótica aplicada a la mejora de la calidad de vida de los ciudadanos.

Apomorphine effects on the hippocampus

Apomorphine is a non-specific dopamine receptor agonist that has been used in the treatment of some diseases and mental disorders. Its use has particularly well documented in Parkinson's disease (PD). The dopaminergic agonists like apomorphine are related to oxidative processes that could induce cell damage and the functional impairment of some structures in the brain. However, most information about apomorphine in literature is focused on the improvement of the motor problems characteristic of PD, but little is known about the effects on cognitive behaviors and brain structures indirectly related to motor function. The presence of dopaminergic receptors in the hippocampus has recently been discovered, in connection with cognitive behaviors like learning and memory, these receptors are needed in neuronal plasticity. There has been a growing interest to know if this structure could be compromised by the effect of apomorphine and elucidate if part of the cognitive impairment present in the PD is due to the effect of apomorphine. In this mini-review, we summarized how apomorphine has been used since its creation, we discuss the latest information about its effect on the hippocampus and also the future perspectives to fully understand the effects of this compound

Position control of a shape memory alloy actuator using a four-term bilinear PID controller

Shape memory alloy (SMA) actuators have a number of appealing features, such as their low weight or their high force-to-weight ratio, that make them a potential alternative to traditional actuation technologies in fields such as space applications, surgical devices or wearable robotics. In this paper, a type of bilinear controller consisting of a conventional PID controller cascaded with a bilinear compensator, known as BPID, is proposed. Bilinear controllers are a subset of nonlinear controllers, which is why the BPID may be a promising alternative to control the position of a SMA actuator. Nonlinear control techniques are commonly applied to control SMA actuators, because of their nonlinear behavior caused by thermal hysteresis. The BPID controller is simpler and easier to implement than other nonlinear control strategies, which makes it a very appealing candidate to control SMA actuators. The performance of the BPID controller has been compared with other two controllers, a conventional PID and a commuted feed-forward PIPD, controlling a real SMA actuator. To this end, a set of five tests has been defined, in which the controlled actuator must follow a series of position references. From these tests, the position and error of the actuator have been plotted, and a series of metrics has been computed to have quantitative measurements of the performance of the three controllers. It is shown that, in most of the experiments, the BPID has a better performance than the other two tested controllers, especially tracking step references. However, the power consumption is slightly higher when the actuator is controlled with this strategy, although-the difference is minimal. Also, the BPID imposes greater energy variations to the SMA actuator, which might affect its service life. Overall, the BPID controller has proved to be a viable alternative to control SMA actuators.The research leading to these results has received funding from the STAMAS (Smart technology for artificial muscle applications in space) project, funded by the European Union’s Seventh Framework Programme for Research (FP7) (grant number 312815), and from the RoboHealth (DPI2013-47944-C4-3-R) Spanish research project

Gene discovery for facioscapulohumeral muscular dystrophy by machine learning techniques

Facioscapulohumeral muscular dystrophy (FSHD) is a neuromuscular disorder that shows a preference for the facial, shoulder and upper arm muscles. FSHD affects about one in 20-400,000 people, and no effective therapeutic strategies are known to halt disease progression or reverse muscle weakness or atrophy. Many genes may be incorrectly regulated in affected muscle tissue, but the mechanisms responsible for the progressive muscle weakness remain largely unknown. Although machine learning (ML) has made significant inroads in biomedical disciplines such as cancer research, no reports have yet addressed FSHD analysis using ML techniques. This study explores a specific FSHD data set from a ML perspective. We report results showing a very promising small group of genes that clearly separates FSHD samples from healthy samples. In addition to numerical prediction figures, we show data visualizations and biological evidence illustrating the potential usefulness of these results.Peer ReviewedPostprint (published version

Evaluación del Entorno de Aprendizaje Clínico con la versión española de la escala CLES+T: el antes y el después de la Declaración de Bolonia

En esencia la enfermería es una profesión basada en la práctica, y consecuentemente, la formación durante las prácticas clínicas de las y los estudiantes, resultan un componente esencial del curriculum de pregrado en el conjunto de países vinculados al Espacio Europeo de Educación Superior. La firma de la Declaración de Bolonia, supuso para los países europeos la implicación en la restructuración del sistema educativo, la adecuación de los programas educativos a la legislación comunitaria, y la promoción de la movilidad de discentes y de docentes entre los mismos. Acontecidos los principales cambios y desarrollados e implantados los programas de pregrado, nos hemos propuesto en este trabajo determinar cómo evalúan los estudiantes del grado en Enfermería de la Universidad de Alicante el entorno de aprendizaje clínico hospitalario, y comparar estos resultados con las evaluaciones emitidas por las/los anteriores estudiantes de la diplomatura. Para tal fin se realiza un estudio transversal en el que se utiliza como instrumento la versión española de la escala CLES+T (Clinical Learning Environment, Supervision and Nurse Teacher)
