EVALUATION OF THE COST-EFFECTIVENESS OF GRID-CONNECTED PHOTOVOLTAIC SOLAR ENERGY IN WINERIES

The objective of this study was to analyze the cost-effectiveness of photovoltaic (PV) solar energy in wineries. The factors analysed were solar radiation, cost of PV installation, prices in the public electricity grid, size of the winery, power of installed panels, influence of the decreased consumption during weekends, and seasonality in the consumption. The study has been based on the European TESLA project, in which 39 energy audits were carried out in wineries in four European countries. A winery of 30,000 hL/year was characterized as a representative winery. The results showed that seasonality was key in the profitability of the system for self-consumption, related to the optimum power to be installed of PV. It was recommended to install, as an optimal PV power, the stable electrical power that is demanded in the daytime period. Optimizing the installed power of PV panels in the representative winery, the percentage of electrical energy consumption covered by photovoltaic energy varied between 16% and 22%. The percentage of the cost of electric energy covered varied between 18% and 24%, with payback values between 18 years (3.1 peak sun hours of solar radiation -PSH) and 10 years (5.6 peak sun hours of solar radiation - PSH). All the factors involved were analyzed

Desarrollo de los componentes sociales de la deportividad en futbolistas alevines

El fútbol base demanda de un tratamiento ético que incluya nosolo aspectos como el respeto, sino también: la cortesía, generosidad y ayuda.El objetivo del presente estudio fue elaborar un programa de intervenciónespecíficamente diseñado para jugadores de fútbol alevín centrado enla mejora de los aspectos sociales de la deportividad y analizar el cambioque genera. Participaron ciento veintiséis (n = 126) futbolistas federados deentre 10 y 12 años de edad. Se utilizó un diseño cuasi-experimental, conuna fase de intervención de seis semanas de duración. Se administró la subescalafactores sociales de la deportividad de la Escala Multidimensionalde Orientaciones hacia la deportividad adaptada al fútbol base (Lamoneda,Huertas, Córdoba y García, 2014). En el análisis estadístico se recurrió a laprueba de Willcoxon y al test exacto de Fisher´s. Se encontraron mejorías enaquellos jugadores que participaron en el programa en la cortesía hacia eloponente, atención e interés por el jugador lesionado y respeto al colegiadoincluso cuando se equivoca. Se hallaron grandes limitaciones en la mejorade la capacidad del jugador para alentar al árbitro a que rectifique una situacióninjusta para el oponente. En el grupo control se apreció un descensode la percepción de conductas de fair play. Los resultados obtenidos en esteestudio permiten pensar que la inclusión de programas educativos en lasplanificaciones deportivas resulta beneficiosa como elemento preventivofrente a la tendencia hacia la pérdida de valores en el fútbol

Local lung immune response to mycobacterium bovis challenge after BCG and M. Bovis heat-inactivated vaccination in European Badger (meles meles)

Tuberculosis (TB) vaccination could be used as a key part of integrated strategies for the disease’s control if an effective and safe vaccine under field conditions is obtained. Recent studies in Spain have evaluated the protective efficacy of two oral vaccines against experimental challenge with live intra-bronchial Mycobacterium bovis in captive badgers: the live-attenuated M. bovis BCG vaccine (Danish strain) and a heat-inactivated M. bovis (HIMB) vaccine. With the objective of increasing the knowledge of the cellular development progress of infection and generating further tools to discriminate between mild and severe TB lesions between and within animals, the immunopathology of tuberculous lesions was studied to characterize the local immune response (cell type profile) within lung granulomas from control (non-vaccinated), BCG vaccinated and HIMB-vaccinated experimentally infected badgers with M. bovis. Four immunohistochemical protocols, for the specific detection of macrophages, T lymphocytes, B lymphocytes and plasma cells within TB granulomas in formalin fixed sections of the right middle lung lobe (lobe targeted for the M. bovis delivery), were performed. Immunolabelled sections were scanned and five randomly selected areas were analyzed with digital image analysis software. The results were expressed as the proportion of the positively immunolabelled area within the total area of the selected site. Data was analyzed using the statistical analysis software (SAS). In the three treatment groups, macrophages were the most abundant inflammatory cells within the granulomas, followed by B lymphocytes and plasma cells. T lymphocyes were absent in those granulomas. This would suggest a predominance of a non-specific innate response mediated by phagocytic cells over an adaptative humoral immune response. The proportion of macrophages and plasma cells was higher in BCG and HIMB-vaccinated badgers, respectively, suggesting the establishment of an adaptative humoral response in HIMB-vaccinated badgers. The lower bacterial load at the lung level, as well as the volume of lesions in lungs using magnetic resonance imaging in badgers with the HIMB vaccine in relation with local immune response presented, must be highlighted, since it would be an advantage in favor of its use under field conditions in terms of reducing TB transmission and environmental contamination.This work has been funded by Ministerio de Ciencia, Innovación y Universidades (MCIU) and the Agencia Estatal de Investigación (AEI) reference project RTI2018-096010-B-C21 (FEDER co-funded) and, by PCTI 2018–2020 (GRUPIN: IDI2018-000237) and FEDER.

Cultivo larvario de atún rojo (Thunnus thynnus) en el Centro Oceanográfico de Murcia (IEO)

In the frame of the SELFDOTT project (From capture based to SELF-sustained aquaculture and Domestication Of bluefin tuna, Thunnus thynnus) captive-reared Atlantic bluefin tuna housed in captivity for 4 years in El Gorguel (Cartagena, Spain) have produced massive spawning, during the natural spawning period for this species in the Mediterranean Sea (June-July) since 2009. Egg collection was accomplished by placing a special curtain around the perimeter of the cage and with collection taking place at night and at sunrise using nets from the surface of the water. Larval rearings were done using pseudogreenwater technique. The survival was of 73 days in 2009 and 110 days in 2010. In 2011 several thousand one month old fingerlings have been produced being transported to floating cages.Este trabajo ha sido llevado a cabo con el soporte financiero de la UE, Proyecto SELFDOTT.

Obtención de puestas masivas de huevos de atún rojo (Thunnus thynnus) en cautividad, durante 3 años consecutivos

Within the framework of the SELFDOTT project, captive-reared bluefin tuna (Thunnus thynnus) maintained in captivity since 2007 in Cartagena (Spain) produced massive spawning during the natural period for this species in the Mediterranean Sea (June-July). The fish were induced with GnRHa implants in 2008 and 2009. In 2008 no spawnings were detected. From 2009, massive spawnings occurred being spontaneous (without hormone implants) in 2010 and 2011. The total egg collection was 140 million in 2009, 60 million in 2010 and 160 million in 2011.7º Programa Marco de la Unión Europea, “Food, Agriculture, Fisheries and Biotechnology" del Proyecto SELFDOTT (From capture based to SELF-sustained aquaculture and Domestication Of bluefin tuna, Thunnus thynnus)” GA 212797

Elevated plasma succinate levels are linked to higher cardiovascular disease risk factors in young adults

Background: Succinate is produced by both host and microbiota, with a key role in the interplay of immunity and metabolism and an emerging role as a biomarker for infammatory and metabolic disorders in middle-aged adults. The relationship between plasma succinate levels and cardiovascular disease (CVD) risk in young adults is unknown. Methods: Cross-sectional study in 100 (65% women) individuals aged 18–25 years from the ACTIvating Brown Adipose Tissue through Exercise (ACTIBATE) study cohort. CVD risk factors, body composition, dietary intake, basal metabolic rate, and cardiorespiratory ftness were assessed by routine methods. Plasma succinate was measured with an enzyme-based assay. Brown adipose tissue (BAT) was evaluated by positron emission tomography, and circulating oxylipins were assessed by targeted metabolomics. Fecal microbiota composition was analyzed in a sub-sample. Results: Individuals with higher succinate levels had higher levels of visceral adipose tissue (VAT) mass (+42.5%), tri‑ glycerides (+63.9%), C-reactive protein (+124.2%), diastolic blood pressure (+5.5%), and pro-infammatory omega-6 oxylipins than individuals with lower succinate levels. Succinate levels were also higher in metabolically unhealthy individuals than in healthy overweight/obese peers. Succinate levels were not associated with BAT volume or activity or with fecal microbiota composition and diversity. Conclusions: Plasma succinate levels are linked to a specifc pro-infammatory omega-6 signature pattern and higher VAT levels, and seem to refect the cardiovascular status of young adults.Spanish Ministry of Economy and Competitiveness via Retos de la Sociedad (DEP2016-79512-R to JRR and RTI2018-093919-B to SFV)European Regional Development Funds (ERDF)Spanish Ministry of Education (FPU16/02828, FPU16/05159, FPU17/01523 and FPU19/01609)University of Granada Plan Propio de Investigación 2016-Excellence actions–Unit of Excellence on Exercise and Health (UCEES)Junta de Andalucía, Consejería de Conocimiento, Investigación y Universidades (ERDF: ref.

Development and clinical evaluation of a simple optical method to detect and measure patient external motion

A simple and independent system to detect and measure the position of a number of points in space was devised and implemented. Its application aimed to detect patient motion during radiotherapy treatments, alert of out-of-tolerances motion, and record the trajectories for subsequent studies. The system obtains the 3D position of points in space, through its projections in 2D images recorded by two cameras. It tracks black dots on a white sticker placed on the surface of the moving object. The system was tested with linear displacements of a phantom, circular trajectories of a rotating disk, oscillations of an in-house phantom, and oscillations of a 4D phantom. It was also used to track 461 trajectories of points on the surface of patients during their radiotherapy treatments. Trajectories of several points were reproduced with accuracy better than 0.3 mm in the three spatial directions. The system was able to follow periodic motion with amplitudes lower than 0.5 mm, to follow trajectories of rotating points at speeds up to 11.5 cm/s, and to track accurately the motion of a respiratory phantom. The technique has been used to track the motion of patients during radiotherapy and to analyze that motion. The method is flexible. Its installation and calibration are simple and quick. It is easy to use and can be implemented at a very affordable price. Data collection does not involve any discomfort to the patient and does not delay the treatment, so the system can be used routinely in all treatments. It has an accuracy similar to that of other, more sophisticated, commercially available systems. It is suitable to implement a gating system or any other application requiring motion detection, such as 4D CT, MRI or PET

Un nuevo grupo de manos paleolíticas pintadas en el sur de la Península Ibérica. La cueva de las Estrellas (Castellar de la Frontera, Cádiz)

Presentamos en este trabajo la revisión de las manifestaciones de arte rupestre conservadas en una estación localizada en la comunidad autónoma de Andalucía, conocida en la literatura precedente como cueva de Las Estrellas (Castellar de la Frontera, Cádiz). Se trata de un abrigo rocoso de grandes dimensiones, abierto al aire libre, en el que ya se había constatado, en los primeros años del presente siglo, la presencia de diversas pictografías de estilo esquemático. Durante una visita reciente al enclave se ha advertido, además, la existencia de un importante conjunto figurativo de cronología paleolítica que incluye representaciones de fauna y una pequeña serie de improntas de manos en negativo. Este artículo aborda el análisis genérico de las grafías catalogadas hasta el momento en la cavidad, atendiendo con especial detalle al conjunto de las citadas huellas de manos paleolíticas, que han sido documentadas usando tecnología digital 3d. De igual modo, se tendrán en cuenta su contextualización en el arte paleolítico andaluz y una primera aproximación cronológica a este interesante y variado complejo figurativo
