Published: November 2017

La migración de menores y jóvenes ha sido tradicionalmente entendida como parte de una estrategia que busca la unión familiar. Y en algunos de los casos es una decisión propia, ante la necesidad de escapar de la violencia intrafamiliar. El fenómeno de los niños y jóvenes que se desplazan solos a través de las fronteras internacionales es cada vez más frecuente. La migración de menores no acompañados no es sino una manifestación de las transformaciones que los procesos migratorios están experimentando en los últimos años. Ante dicha problemática, el estudio hace una descripción y una reflexión sobre las causas y factores que motivan la migración de menores no acompañados, quienes fueron repatriados por la frontera de Reynosa, Tamaulipas-McAllen, Texas, (Estados Unidos), durante el periodo de estudio de enero de 2008 a diciembre de 2009. Así como el género dominante del flujo migratorio, el rango de edad y su nacionalidad.

Published: November 2017

Este artículo permite ampliar el panorama sobre la vasta información existente en la controversia sobre el cultivo de Jatropha curcas y sus posibilidades de producción de aceite para la generación de biodiesel. Se destacan sus múltiples bondades y se discute la falta de estudios básicos científicos que sustenten la implementación de cultivos no solo para el estado de Tamaulipas, sino a nivel nacional, lo que establece restricciones mayores para que esta especie sea un cultivo exitoso para la producción de biocombustibles. Finalmente, se plantean las perspectivas del estudio de otras especies silvestres emparentadas (i.e. Jatropha sotoi-nunyezii), discutida en esta investigación, que en su momento aporten información sobre aspectos fundamentales tales como son: genéticos, ecológicos, ecofisiológicos, sanitarios y agroecológicos, entre otros. Con lo resultante se esperaría contribuir al conocimiento básico necesario, anterior a cualquier propagación vegetal masiva, tanto de ésta, como de otras especies.
Dinámica paisajística y cambio de cobertura en la comunidad indígena de Cuzalapa, Reserva de la Biosfera Sierra de Manantlán (1972 a 2000)
Authors: Cárdenas-Hernández Oscar Gilberto , Gerritsen Peter R.W. 
Published: November 2017

Las transformaciones del paisaje, como los cambios de cobertura y uso del suelo, son procesos que modifican los ecosistemas, particularmente en las áreas tropicales del planeta. Por ello, se analizaron los patrones de cambio en el paisaje de la comunidad indígena de Cuzalapa, ubicada dentro de la Reserva de la Biosfera Sierra de Manantlán, Jalisco, México, durante el periodo comprendido entre 1972 a 2000. Estos patrones se explican a través del estudio de la dinámica agraria de la comunidad desde un enfoque sociológico con la ayuda de la percepción remota. La cobertura en Cuzalapa cambió durante el periodo de estudio, la superficie boscosa disminuyó en casi 20 %, lo que coincidió con la apertura de áreas dedicadas a la agricultura y la ganadería; siendo la expansión ganadera el factor principal de transformación del paisaje de la comunidad. Este es un claro ejemplo de la dinámica agraria y del paisaje en muchas de las comunidades del país, en las que la apertura de áreas para actividades agrícolas y pecuarias, a expensas de las superficies boscosas, ha moldeado el territorio con los consecuentes impactos ambientales y sociales.

Arahan Desain Fasad Koridor Jalan Songoyudan untuk Memperkuat Citra Visual Area Perdagangan Bersejarah di Surabaya
Authors: Rizqiyah Fardilla 
Published: November 2017

Songoyudan road corridor is an essential corridor in the area of CBD I which is located in the Old Town of Surabaya. As a commercial corridor, it is filled by rows of shophouses that sells both variety of goods and secondary needs of most citizens in Surabaya. Initially, the existing buildings are the dutch heritage building which were converted into a shophouses. Yet, there are several shop buildings that has been renovated and reconstructed by the owner into a modern style building. As a corridor which is located both in the developing region and high density of activity, the reducing of the colonial heritage buildings is feared to eliminate the visual distinctiveness of the region. This can also be an unfavorable precedent for other buildings owners when renovating or reconstructing their buildings. So that, their vulnerable heritage building will be reconstructed into a new modern style building that can eliminate the historical value in it. This study aims to find an alternate facade design of shophouses in the corridor as a commercial building which can be used as a reference in designing a new one. The used methodology is descriptive qualitative through technical analysis of visual character of colonial buildings. The elements observed included style, color, texture, pattern, and scale of the building. These findings are expected to provide a guidance to the community, including architects and building owners in reconstructing the existing shophouses especially in the road corridors of Songoyudan and generally in the area of the Old Town Hall Kembang Jepun Surabaya.
Evaluation of the thixoformability of 318.1 aluminum alloy

Published: November 2017

Abstract
The objective of this study was to evaluate the thixoformability of 318.1 aluminum alloy in terms of its thermodynamic, metallurgical and rheological characteristics. The influence of processing parameters on the microstructural evolution of the alloy in the semisolid state and, consequently, its rheological behavior and thixoformability, were studied. The processing parameters investigated were temperature, heating rate and duration of heat treatment. The study was motivated by the dearth of articles in the literature on the thixoformability of this material in industrial environments. The alloy was first subjected to heat treatment to spheroidize its microstructure and observe the microstructural evolution. Hot-pressing tests were then performed to observe the rheological behavior. Micrographs were used to determine average primary-phase grain size, globule size and shape factor. The results confirmed the material to be suitable for semisolid processing from a metallurgical perspective because of its good morphological consistency. Heat treatment successfully spheroidized the microstructure, giving shape factors as high as 0.62 and primary-phase globule and grain sizes as high as 70 μm and 110 μm, respectively. The apparent viscosity was of the order of 105 Pa · s, which is similar to that of liquid glass according to the literature, indicating very good formability. Little variation in the results was observed, showing the suitability of the material for thixoforming from a rheological perspective.
Au fondement de l’altruisme : le lien comme fin

Lorsque l’économie comportementale a voulu s’inspirer des recherches sur l’empathie pour modifier le modèle de l’ homo œconomicus en interaction, elle s’est heurtée à l’impossibilité de penser les émotions dans le cadre d’une théorie des préférences sociales toujours ancrée dans la rationalité du modèle individualiste interactionniste de la théorie des jeux. Cette impossibilité est due au fait que la théorie des jeux tout d’abord, puis l’économie comportementale ensuite, n’ont pas voulu remettre en question l’objectif fondamental de l’individu lorsqu’il agit en interaction avec les autres. Or, se pencher sur la question des émotions et de l’empathie émotionnelle en particulier devait amener à remettre en question les ressorts du comportement. Que nous disent en effet les autres sciences du comportement ? Que si la survie de l’organisme est sans doute un objectif fondamental et commun à tous les êtres vivants, ce dernier tire par ailleurs sa spécificité de mécanismes fondamentaux et pré-câblés qui le spécialisent pour la vie en interaction avec ses semblables. Grâce à ces mécanismes fondamentaux l’espèce humaine a pu élaborer des modes de coopération productifs et sociétaux à grande échelle. Nous proposons en conséquence un changement de perspective en économie comportementale qui permettrait de considérer que l’objectif ultime de l’individu en société n’est pas d’assurer sa survie et ses besoins, mais de créer et d’entretenir le lien aux autres.
Economic Evil and the Other
Authors: Mildenberger Carl David 
Published: November 2017

L’objectif de cet article est double. Premièrement, nous proposons une définition économique du mal. Un agent accomplit une action économique malfaisante s’il blesse (ou incite à blesser) intentionnellement, matériellement, un autre agent, s’il subit une perte matérielle à la suite de cette action et si la possibilité d’un choix plus gratifiant pour lui existait. Deuxièmement, nous discutons de la manière dont nous pouvons catégoriser différentes théories du mal économique et différentes actions économiquement malfaisantes sur la base d’une analyse de la relation entre l’agent malfaisant et l’autre blessé. Notre article met en lumière qu’un type particulier de mal économique n’a pas encore reçu l’attention requise. Ce type de mal économique se caractérise par une relation spécifique entre l’agent et l’autre : l’agent ne se soucie de l’autre que dans la mesure où le gain matériel de l’autre est concerné – et seulement dans la mesure où il s’assure que ce dernier sera négativement impacté par son action. L’article cite également des preuves de tels comportements. JEL Codes : D74, P16, P48, Z13.

Dietary treatment of chronic renal deficiency in dogs and cats.
The aim of nutritional management of chronic renal failure in veterinary practice is to minimize the increase of uraemic toxins in the bloodflow (phosphorus and nitrogenous waste) and to slow the progression of the renal failure, while maintaining a positive nutritional state in a patient with numerous metabolic disorders. In practice, the dietary treatment must be installed early and respect precise nutritional requirements. The patient’s clinical status must be reassessed and its blood levels monitored regularly.

Human cryptosporidiosis : an emerging parasitic disease of increasing importance in public health.
Cryptosporidiosis in human is an emerging parasitosis due to an intestinal and opportunistic protozoan : Cryptosporidium parvum. This parasite was described 100 years ago in calves and lambs. This zoonosis had emerged as a global public health problem in industrial countries for essentially two reasons. One is linked to its potentially life threatening evolution which remains practiccaly incurable, in severely immunocompromised patients (AIDS patients, transplant patients, young children with immature immunological system...). The other is the important warterbome outbreaks in industrial countries. Clinical forms of cryptosporidiosis range from asymptomatic to acute intestinal illness in immunocompetent host. In immunocompromised host, chronic or severe diarrhoeal diseases increase the morbidity and mortality. Moreover extra intestinal dissemination of parasites can accured (cholangitis) and pulmonary cryptosporidiosis are also frequently discribed. This parasitosis is also caracterized by the lack of efficient therapy and insuffisant prophylactic measures. Numerical standard and legal regulation of Cryptosporidium was proposed. Furthermore the oocyts are extremelly resistant to conventional disinfectants. The control of water treatment is necessary to determine the efficiency of prophylactic measures. The significance of different Cryptosporidium parvum isolates could suggested the existence of different transmission cycles in human and merits futher investigations. The virulent potential of Cryptosporidium strains as well as individual susceptibility need further works to a better undestanding of epidemiological risk.
Vegetation greenness and land carbon-flux anomalies associated with climate variations: a focus on the year 2015

Published: November 2017

Abstract. Understanding the variations in global land carbon uptake, and their driving mechanisms, is essential if we are to predict future carbon-cycle feedbacks on global environmental changes. Satellite observations of vegetation greenness have shown consistent greening across the globe over the past three decades. Such greening has driven the increasing land carbon sink, especially over the growing season in northern latitudes. On the other hand, interannual variations in land carbon uptake are strongly influenced by El Niño–Southern Oscillation (ENSO) climate variations. Marked reductions in land uptake and strong positive anomalies in the atmospheric CO2 growth rates occur during El Niño events. Here we use the year 2015 as a natural experiment to examine the possible response of land ecosystems to a combination of vegetation greening and an El Niño event. The year 2015 was the greenest year since 2000 according to satellite observations, but a record atmospheric CO2 growth rate also occurred due to a weaker than usual land carbon sink. Two atmospheric inversions indicate that the year 2015 had a higher than usual northern land carbon uptake in boreal spring and summer, consistent with the positive greening anomaly and strong warming. This strong uptake was, however, followed by a larger source of CO2 in the autumn. For the year 2015, enhanced autumn carbon release clearly offset the extra uptake associated with greening during the summer. This finding leads us to speculate that a long-term greening trend may foster more uptakes during the growing season, but no large increase in annual carbon sequestration. For the tropics and Southern Hemisphere, a strong transition towards a large carbon source for the last 3 months of 2015 is discovered, concomitant with El Niño development. This transition of terrestrial tropical CO2 fluxes between two consecutive seasons is the largest ever found in the inversion records. The strong transition to a carbon source in the tropics with the peak of El Niño is consistent with historical observations, but the detailed mechanisms underlying such an extreme transition remain to be elucidated.
How big is the influence of biogenic silicon pools on short-term changes in water-soluble silicon in soils? Implications from a study of a 10-year-old soil–plant system

Abstract. The significance of biogenic silicon (BSi) pools as a key factor for the control of Si fluxes from terrestrial to aquatic ecosystems has been recognized for decades. However, while most research has been focused on phytogenic Si pools, knowledge of other BSi pools is still limited. We hypothesized that different BSi pools influence short-term changes in the water-soluble Si fraction in soils to different extents. To test our hypothesis we took plant (Calamagrostis epigejos, Phragmites australis) and soil samples in an artificial catchment in a post-mining landscape in the state of Brandenburg, Germany. We quantified phytogenic (phytoliths), protistic (diatom frustules and testate amoeba shells) and zoogenic (sponge spicules) Si pools as well as Tiron-extractable and water-soluble Si fractions in soils at the beginning (t0) and after 10 years (t10) of ecosystem development. As expected the results of Tiron extraction showed that there are no consistent changes in the amorphous Si pool at Chicken Creek (Hühnerwasser) as early as after 10 years. In contrast to t0 we found increased water-soluble Si and BSi pools at t10; thus we concluded that BSi pools are the main driver of short-term changes in water-soluble Si. However, because total BSi represents only small proportions of water-soluble Si at t0 (< 2 %) and t10 (2.8–4.3 %) we further concluded that smaller (< 5 µm) and/or fragile phytogenic Si structures have the biggest impact on short-term changes in water-soluble Si. In this context, extracted phytoliths (> 5 µm) only amounted to about 16 % of total Si contents of plant materials of C. epigejos and P. australis at t10; thus about 84 % of small-scale and/or fragile phytogenic Si is not quantified by the used phytolith extraction method. Analyses of small-scale and fragile phytogenic Si structures are urgently needed in future work as they seem to represent the biggest and most reactive Si pool in soils. Thus they are the most important drivers of Si cycling in terrestrial biogeosystems.

Acquired Factor V inhibitors are a rare condition, associated frequently with at times severe bleeding. Patients can show no symptoms and in exceptional cases thrombosis can be reported. In this article we report two cases of acquired FV inhibitors associated with thrombosis. We systematically reviewed the literature on FV inhibitors and thrombosis. A patient had acquired FV inhibitors and thrombosis. He had no bleeding and was treated with anticoagulant. Despite initial improvement, he died from legionaire’s disease. The second patient had septicemia, acquired FV inhibitors and deep vein thrombosis. The patient’s condition improved with anticoagulation and antibiotic therapy. Ten case reports were considered in the systematic review. The median age at admission was 67. Seven patients had bleeding episodes. The median peak inhibitor titer was 2.7 BU (0.62-8) while the median FV activity was 2% (1-75). Except for 2 patients, all recovered. FV has two activities: a procoagulant action activating prothrombin, as well as an anticoagulant action activating protein C. This property could be associated with thrombosis activity. Inhibitor could also have a through effect on activated protein C. In our study, because of underlying diseases, it was not possible to clearly demonstrate that inhibitors give thrombosis. Immunosuppressive therapies were administered in cases of severe bleeding. Heparin seemed efficient for thrombosis without major bleeding. The prognosis of acquired FV inhibitors appeared to be related to the underlying disease.

<p>Fotovoz es una metodología de investigación-acción participativa que a través de un uso de fotografías y otros recursos producidos por los participantes promueve la reflexión y mejora sobre cuestiones relacionadas con sus propias necesidades y la comunidad a la que pertenecen. Este artículo, constituye un primer acercamiento a la reflexión sobre el papel que fotovoz puede jugar en la promoción de prácticas inclusivas. Basándonos en su desarrollo en una investigación llevada a cabo en seis escuelas de Educación Infantil y Primaria de una misma localidad gallega, se describe dicha metodología y se analiza su posible valor no solo como estrategia de investigación sino también como estrategia didáctica considerando su capacidad para crear y desarrollar procesos y materiales educativos pensados para todos y con la participación de todos. El análisis señala cómo en fotovoz se dan cita cuestiones conceptuales, de carácter epistemológico, ético y práctico, que convergen de manera clara con los principios y planteamientos de la Educación Inclusiva. Esto nos permite resignificar fotovoz como una metodología participativa, de investigación y enseñanza-aprendizaje, de marcado carácter inclusivo.</p>
