Antioxidant, antimicrobial and anti-inflammatory activities of ling-heather honey powder obtained by different methods with several carriers
Get PDFHoney powder is being increasingly used in food, cosmetic and pharmaceutical industry, because it avoids inconveniences of raw honey, such as high viscosity, stickiness and formation of sugar crystals. It is of paramount importance to know if honey powders keep the features of raw honeys. This is the first study, in which total phenolics, total flavonoids, and biological properties of ling-heather (Calluna vulgaris (L.) Hull) honey powders obtained by different drying methods (spray drying, vacuum drying and freeze drying), using different carriers (Arabic gum, whey protein isolate and maltodextrin) were assessed. Results showed that all the drying procedures and carriers retained the honey phenolics in the honey powders. Honey powders' antioxidant activities against different free radicals (ABTS•+, ROO•, •OH and O2•-) were higher than those of the raw honeys, while honey powders’ anti-inflammatory and antimicrobial activities against several microorganisms (Staphylococcus aureus, Listeria monocytogenes and Escherichia coli) were lower. Concentration of honey in the powder and type of carrier used for dehydration were the key factors for the quality of honey powders. However, the drying procedure did not strongly influence the parameters and properties studied.Junta de Castilla y León (Spain) for financial support (BU041G18), and for the research assistant contract given to Ms. Leire Cantero (Grant No. UBU-09-A)

Guía práctica ATEX MADERA
No full textLa presente guía se ha elaborado con el fin de ayudar a los profesionales de la industria de la madera y a los técnicos de prevención, para que conozcan el comportamiento del polvo de madera ya que, en determinadas condiciones, explota.
Este polvo es capaz de generar lo que se conoce como atmósferas explosivas, lo cual sucede cuando sustancias inflamables en forma de gases, vapores, nieblas o polvos mezcladas con el aire y en condiciones atmosféricas, si entran en contacto con una fuente de ignición, pueden encenderse y la combustión se propaga a la totalidad de la mezcla.
Con este trabajo se aportan distintas gráficas y diagramas que sirven como herramientas, junto con el Documento de Protección contra Explosiones, para facilitar la evaluación de riesgos a los técnicos de prevención.Proyecto subvencionado por la Junta de Castilla y León al amparo de la Orden de convocatoria de 210 de marzo de 2019, de la Consejería de Empleo, por la que se convocan para el año 2019, subvenciones públicas para la realización de proyectos de investigación en Prevención de Riesgos Laborales por las Universidades Públicas de Castilla y León
An Intelligent Visualisation Tool to Analyse the Sustainability of Road Transportation
Get PDFRoad transport is an integral part of economic activity and is therefore essential for its development. On the downside, it accounts for 30% of the world’s GHG emissions, almost a third of which correspond to the transport of freight in heavy goods vehicles by road. Additionally, means of transport are still evolving technically and are subject to ever more demanding regulations, which aim to reduce their emissions. In order to analyse the sustainability of this activity, this study proposes the application of novel Artificial Intelligence techniques (more specifically, Machine Learning). In this research, the use of Hybrid Unsupervised Exploratory Plots is broadened with new Exploratory Projection Pursuit techniques. These, together with clustering techniques, form an intelligent visualisation tool that allows knowledge to be obtained from a previously unknown dataset. The proposal is tested with a large dataset from the official survey for road transport in Spain, which was conducted over a period of 7 years. The results obtained are interesting and provide encouraging evidence for the use of this tool as a means of intelligent analysis on the subject of developments in the sustainability of road transportation

Preparation of Water-in-Oil Nanoemulsions Loaded with Phenolic-Rich Olive Cake Extract Using Response Surface Methodology Approach
Get PDFIn this study, we aimed to prepare stable water-in-oil (W/O) nanoemulsions loaded with a
phenolic-rich aqueous phase from olive cake extract by applying the response surface methodology
and using two methods: rotor-stator mixing and ultrasonic homogenization. The optimal nanoemulsion formulation was 7.4% (w/w) of olive cake extract as the dispersed phase, and 11.2% (w/w) of
a surfactant mixture of polyglycerol polyricinoleate (97%) and Tween 80 (3%) in Miglyol oil as the
continuous phase. Optimum results were obtained by ultrasonication for 15 min at 20% amplitude,
yielding W/O nanoemulsion droplets of 104.9 ± 6.7 nm in diameter and with a polydispersity index
(PDI) of 0.156 ± 0.085. Furthermore, an optimal nanoemulsion with a droplet size of 105.8 ± 10.3 nm
and a PDI of 0.255 ± 0.045 was prepared using a rotor-stator mixer for 10.1 min at 20,000 rpm. High
levels of retention of antioxidant activity (90.2%) and phenolics (83.1–87.2%) were reached after
30 days of storage at room temperature. Both W/O nanoemulsions showed good physical stability
during this storage period.Junta de Castilla y León (JCyL) and the European Regional Development Fund (ERDF) through grant number BU050P20, and by the Agencia Estatal de Investigación (grant number PID2019-104950RB-I00/AEI/10.13039/501100011033)
The Contribution of Interdisciplinary Education to the Development of Students Competences with Intellectual Disabilities. An Analysis from the Social and Rights Model
No full textInterdisciplinary education is presented as an opportunity to address the challenges of education, especially in the case of the most vulnerable groups. People with intellectual disabilities, because of their specific cognitive processes that influence their learning, have particularly suffered the consequences of school exclusion. In recent years, international treaties have addressed the inclusive education of people with disabilities as one of the problems to be tackled, in a context of diversity and learning for all, and at all stages of life. In the face of difficulties, the foundations that define interdisciplinary education make it a good practice for achieving equal educational opportunities, by addressing content in a holistic way that is close to real problems. This chapter delves into interdisciplinary education as a strategy available for the learning of people with intellectual disabilities, under the approach of the social and rights model, establishing links between the context and the person through new approaches, thus offering a new framework of opportunities for lifelong, quality and inclusive learning
Preventing violent extremism in youth through sports: An intervention from the 3N model
No full textPreventive approaches have gained weight with regard to violent extremism. However, although the number of
interventions aimed at prevention has increased, many of them do not have a solid theoretical basis and very few
have been evaluated, so we do not know the real impact of these interventions. Based on these limitations, a
sport-based intervention program was designed to prevent violent extremism. Using the 3N model of radicalization as a theoretical reference, the program was designed and implemented trying to influence the needs,
narratives, and social networks of the participants. Thus, the objective of the present research was to evaluate the
impact of the program, for which two studies were designed. The first study used a quantitative approach using
questionnaires that were answered by the participants and by a control group. The second study used a qualitative approach that included open-ended questionnaires that were completed by the participants’ referents.
Both studies assessed the needs, narratives, and social networks of the participants. Overall, the results showed
an improvement in social networks and differences in the effects on needs and narratives depending on the study.
We conclude by highlighting the role of sports-based interventions in generating a sense of belonging and
improving social support as preventive factors.This work was supported by the European Commission [grant SANT-609085F8]
