    Relationships between texture, pH, organic matter and exchange capacity in the top horizon of a soil over serpentlnes

    [Abstract] A statistical analysis of texture, pH, organic matter content and CEC in the rop horizon of a soil over serpentine underneath was undertakan. The studied properties showed a considerable variability. Significant correlations were deteeted between organic matter content, day content and CEe. Likewise these three ahead mentioned properties were correlated with exchangeable Ca and Mg. In the exchange complex Mg prevailed over Ca so that the ration Cal Mg was low and was found ro increase as the pH diminished

    [Abstract] To investigate the spatial behavior of topsoil Fe, Mn, Cu and Zn in a small (1,8 ha) field 53 samples were taken acording to a nested sampling pattern. Metal contents extracted by 0.05 EDTA, both at pH = S and pH = 7 were analyzed and the Fe, Mn, CuandZndegree ofbinding was assessed by a mobility . index, calculated as the difference between the concentrations released at pH = S and at pH = 7. Both the extractable content and the mobility index of these four metals displayed a wide range of variability. As expected, at the pHs range studied, field-averaged solubility was constant for Fe and increased for the other metals following the rank Zn =:: Cu < Mn. Mobility indexdata analyzed bygeostatistical techniques, specificallyvariogram computation, were found to have a spatial structure. Block-kriged contourmaps allowed to identify microregions with significantly increased risk ofMn, Cuand Zn mobilization. Organic matter content, exchangeable cation capacity and silt content appeared to be the main factors responsible for the observed distribution of metals extractability and mobility index within the studied field.

    Parásitos intestinales en fangos de depuradora y posible riesgo asociado a su reutilización

    Get PDF
    La reutilización de fangos de salida de depuradora se ha convertido en un valioso recurso dado su contenido en nutrientes. Sin embargo, puede suponer un riesgo para la salud pu´blica si su higienización no es adecuada, por la variedad de potenciales pato´genos que pueden contener. La normativa vigente sobre reutilización de fangos (RD 1310/90 y AAA/1072/2013) únicamente hace referencia a la presencia de E. coli y Salmonella spp. Sin embargo, varios estudios sugieren que el uso tradicional de bacterias indicadoras de contaminacio´n fecal no predice la presencia de otros pato´genos como para´sitos y protozoos1. Giardia duodenalis, Cryptosporidium spp. o Entamoeba spp. son protozoos distribuidos mundialmente, causantes de trastornos gastrointestinales en gran número de hospedadores y transmitidos principalmente por el consumo de agua y alimentos de consumo crudo contaminados

    Lichen Sclerosus et Atrophicus with Cutaneous Distribution Simulating Lichen Planus

    Get PDF
    Lichen sclerosus (LS) et atrophicus is a disease of unknown etiology, although hereditary, endocrine, and autoimmune factors are known to be involved. While the anal and genital regions are predominantly affected, only 2.5% of patients present with extragenital lesions, particularly of the trunk, neck, and upper limbs. The possible relationship between lichen sclerosus et atrophicus and both lichen planus (LP) and localized scleroderma (morphea) has not been clearly established, although in a number of cases, several of these conditions have been found simultaneously. We report the case of a 31-year-old woman with LS lesions affecting the neck, upper back, wrist and dorsum of the feet. The unusual character of this presentation is pointed out, along with its clinical similarity to LP

    The Effect of Balance Training on Postural Control in Patients with Parkinson s Disease Using a Virtual Rehabilitation System

    Get PDF
    [EN] Objectives: Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by motor clinical alterations among others. Postural problems have serious consequences for patients, not only limiting their daily life but also increasing some risks, like the risk of fall. Inadequate postural control and postural instability is a major problem in PD patients. A Virtual Motor Rehabilitation System (VMR) has been tested in patients with PD in the intervention period. Our pur-pose was to analyze the evolution of the spatial postural control during the intervention period, to see if there are any changes caused precisely by this intervention. Methods: Ten people with PD carried out 15 virtual rehabilitation sessions. We tested a groundbreaking system based on Virtual Motor Rehabilitation in two periods of time (baseline evaluation and final evaluation). In the training sessions, the participants performed a customizable treatment using a low-cost system, the Active Balance Rehabilitation system (ABAR). We stored the pressure performed by the participants every five hundredths of a second, and we analyzed the patients' pressure when they maintained their body on the left, on the right, and in the center in sitting position. Our system was able to measure postural control in every patient in each of the virtual rehabilitation sessions. Results: There are no significant differences in the performance of postural control in any of the positions evaluated throughout the sessions. Moreover, the results show a trend to an improvement in all positions. This improvement is especially remarkable in the left/right positions, which are the most important positions in order to avoid problems such as the risk of fall. With regard to the suitability of the ABAR system, we have found outstanding results in enjoyment, success, clarity, and helpfulness. Conclusions: Although PD is a progressive neurodegenerative disorder, the results demonstrate that patients with PD maintain or even improve their postural control in all positions. We think that the main factor influencing these results is that patients use more of their available cognitive processing to improve their postural control. The ABAR system allows us to make this assumption because the system requires the continuous attention of patients, promoting cognitive processing.This contribution was partially funded by the Gobierno de Aragon, Departamento de Industria e Innovacion, y Fondo Social Europeo "Construyendo Europa desde Aragon" and by the Programa Ibercaja-CAI de Estancias de Investigacion.Albiol-Perez, S.; Gil-Gómez, J.; Muñoz-Tomás, M.; Gil Gómez, H.; Vial Escolano, R.; Lozano Quilis, JA.

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

    Get PDF
    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
