Estudio de basaltos mediante espectroscopía de plasma inducido por láser (LIBS) para la fabricación de bloques de lapilli

Se analizaron mediante espectroscopía de plasma inducido por láser (LIBS), espectroscopía Raman y difracción de rayos x (XRD) muestras seleccionadas de diversas zonas de Tenerife, con el objetivo de identificar su composición química elemental y mineralógica. Los resultados mostraron los elementos mayoritarios siguientes: O, F, Na, K, Mg, Al, Si, Ca, Ti y Fe. La identificación de las muestras, mediante espectroscopía Raman y XRD, mostró una mineralogía de tipo basáltica coincidente con los resultados de composición elemental LIBS. Los resultados de los análisis con instrumentación portátil demuestran la aplicabilidad de la espectroscopía LIBS y, en especial, en combinación con la espectroscopía Raman, para su utilización en la detección mineralógica-química en las zonas de extracción de basaltos y picón para la construcción en Tenerife

e-VALUACIÓN en tiempo real

Los sistemas de evaluación de prácticas actuales, incluyendo los automáticos, plantean el problema de que un estudiante entrega una práctica y no sabe la nota hasta transcurrido un tiempo, sin darle la posibilidad de corregir sus errores. Todo esto puede provocar en el estudiante desmotivación, abandono, falta de seguimiento, desconocimiento y, consecuentemente, el suspenso. Como una forma de solucionar este problema y teniendo en cuenta nuestro trabajo y aportaciones en los proyectos de investigación docente referidas al Espacio Europeo de Educación Superior (EEES, ver [1] y [2]), planteamos la evaluación de prácticas mediante un sistema automático de control de entrega online, disponible las 24 horas del día, y con carácter objetivo al 100%. Dicho sistema presenta muchas ventajas tanto para el estudiante (actualización instantánea de la nota, feedback inmediato para corregir posibles fallos) como para el profesor (dedicar más tiempo a enseñar y no a corregir, seguimiento continuo del trabajo de los estudiantes).Peer Reviewe

Characteristics of vineyard soils derived from Plio-Quaternary landforms (raña or rañizo) in southern Europe

Soil is an essential component in viticulture. The study reported here concerns the assessment of the morphology chemical and physicochemical features of typical, well-developed and representative evolved Mediterranean soils near Anchuras (Spain, southern Europe), a site with soils that developed on old landforms (Plio-Quaternary) called ‘raña’ and/or ‘rañizo’. The soils under study were described and sampled by conducting soil surveys. Selected soil properties, such as texture, bulk density, pH, electrical conductivity (EC), cation exchange capacity (CEC) and contents of organic matter, nutrients, etc., were analysed using standard procedures. The results showed that these landscape surfaces were, linked with specific soil properties such as low pH (from 4.4 to 5.3) and EC (from 0.15 to 0.02 dSm 1 ), clay contents (20.1%–48.8%), high CEC (26–39 cmol/kg), and low base saturation values (from 11.2% to 17.2%), and have an adequate and singular pedological potential in relation to the ‘terroir’ or ‘terron’ concepts that meet suitability criteria. Furthermore, the information provided by this study, fundamentally through the weathering indices, supports the role of soil-forming factors and their influence on soil properties. In addition, as these landforms and underlying materials have abundant and extensive rock fragments, the role of these soils in the context of vineyard growth and development has been investigatedThis research was supported by the Winerin Eldoze (Project number UCTR180065

Cognitive status among patients with chronic obstructive pulmonary disease

We investigated the association between cognitive impairment and chronic obstructive pulmonary disease (COPD), taking into account demographic and clinical variables evaluated during routine practice. We performed a post hoc analysis of a cross-sectional study that included subjects with stable COPD. Sociodemographic and clinical information was recorded using the Body mass index, airflow Obstruction, Dyspnea and Exacerbations index and the Charlson comorbidity index. Cognitive performance was studied by the mini-mental state examination, with a score less than 27 indicating clinical impairment. Depressive symptoms, physical activity, and quality of life (EuroQoL-5 dimensions and COPD Assessment Test) were also evaluated. The analysis included 940 subjects. The prevalence of cognitive impairment was 39.4%. Multivariate logistic regression models revealed that cognitive impairment was associated with educational level (odds ratio [OR] =0.096, 95% confidence interval [CI] =0.011-0.447) and poorer quality of life measured by the EuroQoL-5 dimensions social tariff (OR =0.967, 95% CI =0.950-0.983). When questionnaires were not included in the analysis, cognitive impairment was associated with educational level (OR =0.063, 95% CI =0.010-0.934), number of exacerbations (OR =11.070, 95% CI =1.450-84.534), Body mass index, airflow Obstruction, Dyspnea and Exacerbations index score (OR =1.261, 95% CI =1.049-1.515), and the Charlson comorbidity index (OR =1.412, 95% CI =1.118-1.783). Cognitive impairment is common in COPD and is associated with low educational level, higher disease severity, and increased comorbidity. This could have therapeutic implications for this population

A morphological approach to evaluating the nature of vineyard soils in semiarid Mediterranean environment

La Mancha (Central Spain) is one of the most extensive vineyard regions in the world, and ‘Valdepeñas’ is a representative Protected Denomination of Origin (PDO) in this region. However, what are their main soil types? what kind of horizons are the most common? and what is the role of the geomorphological positions in their pedodiversity? After describing and sampling 90 soil profiles in this area, Alfisols, Inceptisols and Entisols were mainly identified in Soil Taxonomy terms; in other words, Luvisols, Cambisols, Regosols, Leptosols and a highly significant proportion of Calcisols according to FAO-UNESCO-ISSS. The accumulation of carbonate, the thickness of which varies from a diffuse or powdery form to crusted forms, appear sometimes like polycyclic. The presence of red soils, with or without a calcic or petrocalcic horizon, indicates the most representative edaphic stages in this region. Consequently, the morphological signature is calcic or petrocalcic, followed by argillic and/or cambic horizons, under ochric horizons. It can be concluded that the nature of soils in Valdepeñas can be considered a differential factor to bear in mind for quality viticultural production. Highlights: There are unknown conceptual zones in support production of wine. A comprehensive study in a local case was performed due to its traditional production of vineyards. This study highlights the importance and uniqueness of the calcic and petrocalcic horizons. A disconnect exists between some tradicional viticultural zones with low reputation and the real value of their soil

Reproductive desire in women with HIV infection in Spain, associated factors and motivations: A mixed-method study

Background: Antiretroviral therapy has created new expectations in the possibilities of procreation for persons living with HIV. Our objectives were to evaluate reproductive desire and to analyze the associated sociodemographic and clinical factors in HIV-infected women in the Spanish AIDS Research Network Cohort (CoRIS).Methods: A mixed qualitative-quantitative approach was designed. Women of reproductive age (18-45) included in CoRIS were interviewed by phone, and data were collected between November 2010 and June 2012 using a specifically designed questionnaire. Reproductive desire was defined as having a desire to be pregnant at present or having unprotected sex with the purpose of having children or wanting to have children in the near future.Results: Overall, 134 women were interviewed. Median age was 36 years (IQR 31-41), 55% were Spanish, and 35% were unemployed. 84% had been infected with HIV through unprotected sex, with a median time since diagnosis of 4.5 years (IQR 2.9-6.9). Reproductive desire was found in 49% of women and was associated with: 1) Age (women under 30 had higher reproductive desire than those aged 30-39; OR = 4.5, 95% CI 1.4-14.3); 2) having no children vs. already having children (OR = 3.2; 1.3-7.7 3); Being an immigrant (OR = 2.2; 1.0-5.0); and 4) Not receiving antiretroviral treatment (OR = 3.6; 1.1-12.1). The main reasons for wanting children were related to liking children and wanting to form a family. Reasons for not having children were HIV infection, older age and having children already. Half of the women had sought or received information about how to have a safe pregnancy, 87% had disclosed their serostatus to their family circle, and 39% reported having experienced discrimination due to HIV infection.Conclusions: The HIV-infected women interviewed in CoRIS have a high desire for children, and the factors associated with this desire are not fundamentally different from those of women in the general population. Maternity may even help them face a situation they still consider stigmatized and prefer not to disclose. Health-care protocols for handling HIV-positive women should incorporate specific interventions on sexual and reproductive health to help them fulfill their procreation desire and experience safe pregnanciesThe RIS cohort (CoRIS) is funded by the Instituto de Salud Carlos III through the Red Temática de Investigación Cooperativa en Sida (RIS C03/173
