Spanish’s experience on improving inspection of sprayers: official manual for ISO 16122 and ISO 16119

Mandatory inspections in Spain are organized following ISO 16122. In order to guarantee a clear and comprehensive inspection’s procedure in all of the official inspection’s workshops, the Spanish Ministry of Agriculture published an official inspection’s manual based on ISO 16122 in order to improve and harmonize the process. On the other hand, and considering the more and more cases of new sprayers with difficulties to fulfill the mandatory inspections requirements, an official manual for sprayer’s manufacturers have been published in collaboration with the Spanish Association of Agricultural Machinery Manufacturers (ANSEMAT) giving them a practical document to fulfill the requirements established in ISO 16119. Both documents have been written by the research team of UMA-UPC. In this paper will be presented the objectives, structure and success of the two official manuals.Mandatory inspections in Spain are organized following ISO 16122.

The mean age of subjects was 57.6 ± 15.4 years. To be eligible, subjects’ tear film break-up time (TFBUT) had to be <10 seconds, and subjects had to have at least one ocular discomfort symptom in addition to dryness. Saline was used for a wash-out period of 3–5 days. Subjects were re-examined, and those continuing to meet the inclusion criteria were dispensed Systane® and re-examined again after 28 days. At each visit, slitlamp examination was conducted, and ocular discomfort symptoms and TFBUT were evaluated. Subjects rated their overall satisfaction at baseline and on the last visit.Results: No significant changes in TFBUT or ocular discomfort symptoms were observed after saline use, compared with screening visit. After 28 days of Systane® use there was statistically significant improvement of TFBUT (p = 0.0001) compared with baseline. Subjects experienced significant symptomatic relief for all 6 ocular discomfort symptoms at the endpoint visit.Conclusion: Systane® effectively relieved the symptoms associated with moderate ocular dryness, with measurable improvement in objective TFBUT, subjective symptoms, and overall satisfaction.Keywords: Systane, lubricant eye drops, TFBUT, ocular dryness, ocular symptom

Older adults and sport and physical activity professionals in Spain

Presence of monitors in physical activities and sports practiced by adults older than 64 years of age in Spain is analyzed in this research. The objective of this study is to determine the existence of monitors in relation to the sociodemographic features of older adults, the size of municipalities, the activities practiced, and the organizations where they are performed. The methodology used included a cross-sectional survey applied to a sample of older adults in Spain. The most relevant conclusions are that the presence of monitors in physical activities and sports practiced by older adults is dominant (63.8%), hence, their importance, and that the presence of monitors is higher for women (81.3%) than for men (37.5%). In addition, it is concluded that the bigger the municipality the higher the tendency to have more instructors. Regarding the type of activity, wide diversification is obtained; finally, there is a larger presence of monitors in sports entities (87.5%) and nursing homes (79.5%)

Producción y evaluación de un biosurfactante para la biorremediación de suelos contaminados con hidrocarburos

147 páginas. Doctorado en Ciencias e Ingeniería de Materiales.Los crudos pesados están constituidos por diferentes fracciones de asfaltenos, resinas, compuestos aromáticos y saturados, que contribuyen a sus altas viscosidades, por lo que son intrínsecamente difíciles de biodegradar. Por otro lado, los suelos contaminados que contienen rocas calizas son preferiblemente mojables a los aceites, lo que dificulta su remoción. Los biosurfactantes son capaces de modificar la mojabilidad en el sistema roca/aceite/agua y reducir la tensión interfacial, lo que promueve la liberación del aceite, haciéndolo biodisponible. Este trabajo tuvo como objetivo producir y evaluar un biosurfactante biosintetizado por una cepa de Bacillus subtilis para mejorar la biodegradación del crudo pesado impregnado en arena de caliza. Se realizó la producción del biosurfactante en un reactor agitado de 3L. La actividad biosurfactante se determinó a diferentes temperaturas, pH y salinidades para establecer su estabilidad. Se evaluaron la tensión interfacial y el ángulo de contacto para determinar los mecanismos involucrados en la liberación de aceite pesado. Finalmente, se dilucidó el efecto del biosurfactante sobre la liberación del aceite pesado impregnado en arena de caliza, para su posterior biodegradación utilizando una cepa de Rhodococcus sp. Se encontró que la tasa máxima de producción de CO₂, utilizada como indicador de actividad biológica, mejoró en un 32.84% en los sistemas donde se utilizó biosu factante, en comparación con aquellos donde no se usó. Al menos el 67% de la fracción > C₂₀ se degradó en los sistemas con biosurfactante, reduciendo las fracciones aromática y de resinas (12.5% y 2%, respectivamente), mientras que en los sistemas sin biosurfactante solo se eliminó el 37% de la fracción> C₂₀ y la reducción de aromáticos y resinas fue nula. El biosurfactante demostró ser efectivo en la liberación del crudo y mejoró notablemente el proceso de biodegradación.Heavy crude oils are comprised of different fractions of asphaltenes, resins, aromatic and saturated compounds, which contribute to their high viscosities, making them intrinsically difficult to biodegrade. Besides, contaminated soils that contain limestone rocks are preferably oil wet, which makes their removal difficult. Biosurfactants are capable of modifying the wettability of rock/oil/water system and reduce interfacial tension, which promotes the release of oil, making it bioavailable. The objective of this work was to produce and evaluate a biosurfactant biosynthesized by a strain of Bacillus subtilis to improve the biodegradation of a heavy crude oil impregnated in limestone sand. The biosurfactant production was carried out in a 3L stirred reactor. The biosurfactant activity was determined at different temperatures, pH and salinities to establish its stability. Interfacial tension and contact angle were evaluated to determine the mechanisms involved in heavy oil release. Finally, the effect of the biosurfactant on the release of heavy oil impregnated in limestone sand was elucidated, for its subsequent biodegradation using a strain of Rhodococcus sp. It was found that the maximum CO₂ production rate, used as an indicator of biological activity, improved by 32.84% in systems where biosurfactant was used, compared to those where it was not used. At least 67% of the fraction > C₂₀ was degraded in the systems with biosurfactant, reducing the aromatic and resin fractions (12.5% and 2%, respectively), while in systems without biosurfactant only 37% was removed of the fraction > C₂₀ and the reduction of aromatics and resins was null. The biosurfactant proved to be effective in the release of crude oil and significantly improved the biodegradation process.Investigación realizada con el apoyo del Programa Nacional de Posgrados de Calidad del Consejo Nacional de Ciencia y Tecnología (CONACYT)

ET-1 plasma levels, choroidal thickness and multifocal electroretinogram in retinitis pigmentosa

Aim To assess the relationship between both photoreceptor function and choroidal thickness and endothelin-1 (ET-1) plasma levels in patients with early stage retinitis pigmentosa (RP). Main methods We compared 24 RP patients (14 males and 10 females), 25 to 42 years of age (mean age: 34 ± 7 years) with 24 healthy controls (12 males and 12 females) aged between 28 and 45 years (mean 36 ± 6.8 years). All patients underwent visual field test, electroretinogram and multifocal-electroretinogram and choroidal thickness measurement by using spectral domain optical coherence tomography. Key findings RP patients had a visual acuity of 0.95, a mean defect of the visual field of − 7.90 ± 1.75 dB, a pattern standard deviation index of 6.09 ± 4.22 dB and a b-wave ERG amplitude of 45.08 ± 8.24 μV. Notably RP subjects showed significantly increased ET-1 plasma levels and reduced choroidal thickness compared with controls: respectively, 2.143 ± 0.258 pg/ml vs. 1.219 ± 0.236 pg/ml; p < 0.002 and 226.75 ± 76.37 μm vs. 303.9 ± 39.87 μm; p < 0.03. Spearman's correlation test highlighted that the increase of ET-1 plasma levels was related with the decrease of choroidal thickness (r = − 0.702; p < 0.023) and the increase of implicit time in both ring 2 (r = − 0.669; p < 0.034) and ring 3 (r = − 0.883; p < 0.007) of mfERG. Significance Increased ET-1 plasma levels may play a key role in the impairment of retinal and choroidal blood flow due to the vasoconstriction induced by ET-1. This could lead to worsening of the abiotrophic process of the macular photoreceptors
