La integración de la educación ambiental en la ESO : datos para la reflexión

We present in this paper the analysis and principal results of a research carried out among 438 teachers and 126 headmasters. The issues concern the situation of environmental education in Obligatory Secondary School. The purpose of the study was to identify teacher and headmaster's opinions, perceptions and feelings about the situation of environmental education in their centres

Dietary pesticide chlorpyrifos-methyl affects arachidonic acid metabolism including phospholipid remodeling in Atlantic salmon (Salmo salar L.)

The pesticide chlorpyrifos-methyl (CLP-m) has been identified in plant ingredients intended for aquaculture feed production. To investigate systemic effects of CLP-m with emphasis on lipid metabolism, post-smolt Atlantic salmon were fed in duplicate (n = 2) either diets with no CLP-m (Control) or CLP-m at different concentrations (0.1, 1.0 or 8.0 mg kg(-1)) for a total of 67 days (Low, Medium, High). Fish in all groups almost doubled their weight during the feeding trial from 262 +/- 26 g (mean +/- SD) to 465 +/- 64 g (overall mean), with no significant effects on any growth parameters. There was a significant dose-dependent inhibition of plasma cholinesterase activity (BuChE) after 67 days. The CLP-m biotransformation metabolite, TCP was detected in liver and bile, with low levels of the parent compound in the organs. Spleen somatic index decreased significantly with increasing dietary CLP-m intake. Hematocrit (%) decreased linearly with increasing dietary exposure to CLP-m after 30 days of exposure, but this decrease was less at 67 days of exposure. A significantly reduced content of arachidonic acid (ARA 20:4n - 6), accompanied by a significantly increased content of the saturated fatty acid, palmitic acid (PA 16:0), was observed in liver phospholipids (PLs) with increasing dietary content of CLP-m. Major effects were seen on the PL classes in liver which showed a significantly decreased absolute content, possibly indicating inhibition of PL remodeling pathways or other membrane perturbation effects from CLP-m exposure. In conclusion, this study shows that the pesticide CLP-m is a relatively potent toxicant in Atlantic salmon, especially affecting liver PLs and ARA metabolism

Photocatalytic fabrics based on reduced graphene oxide and TiO2 coatings

Supplementary data associated with this article can be found, in the online version, at: http://dx.doi.org/10.1016/j.mseb.2015.04.013The purpose of this work is to obtain photocatalytic fabrics based on reduced graphene oxide (RGO) and TiO2 coatings on polyester fabrics. The influence of the applied number of RGO coatings on properties such as light absorption, conductivity, electroactivity and photocatalytic properties of the fabrics was established. An improvement of these properties with the number of RGO coatings applied was obtained. FESEM, EDX, XPS and FTIR-ATR showed the incorporation of the TiO2 nanoparticles on the fabrics. FTIR-ATR showed the formation of a bidentate carboxylic ligand with titanium atoms. The photocatalytic properties of the fabrics were tested with Rhodamine B dye solutions. Photocatalytic efficiency increased with the number of RGO coatings, due to the increased light absorption, and better electrical properties. The charge transfer resistance (Rct) and its time constant (τ) decreased, indicating a better electron transfer which helps to increase the lifetime of the pair electron/hole.Authors wish to thank to the Spanish Ministerio de Ciencia e Innovación (contract CTM2011-23583) for the financial sup port.

Superficial radiotherapy as haemostatic treatment in breast cancer

Poster Session [EP-1661] Purpose or Objective Breast cancer is a common pathology in which o = 25% in tumor size and absence of bleeding was observed. Conclusion Surface radiotherapy is a treatment modality that should be taken into account in patients with breast cancer who present bleeding as a consequence of local tumor growth, given that this is a treatment comfortable for the patient, non invasive and increases the quality of patient’s life

Reversal of economic fortunes: institutions and the changing ascendancy of Barcelona and Madrid as economic hubs

This paper looks at the divergent economic trajectories of Barcelona and Madrid since Spain's transition to democracy. It highlights how Barcelona, the city that was better positioned four decades ago to emerge as the main Spanish economic hub, has lost out to Madrid. We argue that the contrasting trajectories of the two cities have less to do with the pull of Madrid as the capital of Spain, with the development of new infrastructure in the country, or with agglomeration economies, and more with institutional factors. A growing societal divide in Barcelona along economic, social, and identity lines has led to a greater breakdown of trust and to the development of strong groups with limited capacity to bridge with one another than in Madrid. This has entailed the emergence of negative externalities that have limited the economic potential for growth in Barcelona and facilitated the rise of Madrid as the main economic hub within Spain

Territorio, lugares y salud : redimensionar lo espacial en salud pública

RESUMEN: El propósito de este escrito es avanzar en la lectura del proceso de salud-enfermedad en clave territorial. La teorización sobre el vínculo salud y ambiente debe extenderse desde las tipologías médicas, y su énfasis en la distribución del riesgos ambientales (físico, biológico, químico), hacia el reconocimiento de la producción social y subjetiva de los territorios. Para avanzar en esta teorización la salud pública debe enriquecerse con la integración de nociones propias de las ciencias sociales como la apropiación del espacio, territorio-territorialidades y lugares. Además, ha de orientarse desde una mirada escalar hacia los microterritorios, pues es en el escenario de los territorios locales y en los lugares cotidianos de la vida, donde se concretan los modos de vivir, de enfermar y de construir salud
