Effect of ultrasonication on microbial quality, colour and ascorbic acid of passion-fruit juice during storage

Passion fruit juice (PFJ) has a delicate flavour very susceptible to thermal degradation. This study pursued to test the effect of sonication as non-thermal preservation method on some quality parameters of PFJ. The effect of ultrasound (20 kHz, 263 W, 89.25 µm) on the indigenous microflora, colour and ascorbic acid content of PFJ was studied. Firstly, the kinetic of microbial inactivation was determined for aerobic mesophilic counts and yeasts counts. Data was fitted to Weibull model, and a treatment time of 8 min was selected for stability studies. To this, untreated and sonicated juice was stored at 4 and 10 ºC up to 10 days and microbial quality, instrumental colour, pH and ascorbic acid content were evaluated. In general, ultrasound kept juice microbiologically stable for up to 10 days at 4 ºC without markedly affecting other parameters evaluated. Ultrasound seems suitable to stabilize microbiologically PFJ.Ciencias de la Alimentació

Aesthetical Appeal and Dissemination of Architectural Heritage Photographs in Instagram

Image-based social networks are environments where users share their photographs and involuntarily contribute to evolve and to spread the meaning of things. For this reason, it is essential to use this source of information to determine how people perceive cultural heritage, specifically building heritage. These interactive spaces have a visual component that is essential to understand users' perception of heritage architecture and that may also influence the dissemination of images. This research aims to describe the social concept of architectural heritage on Instagram and to explore whether the aesthetic appeal resources influence its dissemination. Images indexed to the hashtag #patrimonioarquitectonico (Spanish language version of #architecturalheritage) were collected for the period of three months (n = 180 images). A graphical and observational analysis was performed on categories of four variables of aesthetical appeal: human dimension, color, linear perspective and aesthetical quality. Subsequently, descriptive, cross-tabulation and variance analyses were applied. The findings have proven that regular users share a fairly heterogeneous vision of building types concerning architectural heritage, and that there are stakeholder accounts that could be altering their meaning due to strategies to protect residential areas. The paper describes how the aesthetic appeal variables add meaning to the social perception of the building heritage and which ones statistically influence its dissemination in terms of likes and engagement on Instagram

Purpose Adequacy as a Basis for Sustainable Building Design: A Post-Occupancy Evaluation of Higher Education Classrooms

[Abstract] Building design is one of the essential elements to consider for maximizing the sustainability of construction. Prior studies on energy and resource consumption and on indoor environmental quality indicators (IEQs) are increasingly frequent; however, attention has not been focused on design as supporting the function performed within architecture. Educational buildings have specific conditions related to teaching methodologies, including activating students and promoting participation and interaction in the classroom. This manuscript aims to explore whether the social dimension of physical space in educational settings can explain a student’s academic outcome. For this, the Learning Environment and Social Interaction Scale was designed and validated and applied to 796 undergraduate students at the University of Coruña, and multiple linear regression analysis was applied to the academic results. The results display a structure comprising five factors; these include novelties such as the division of conventional IEQs into two groups: the workspace and the classroom environment. In addition, place attachment, the design of the classroom as a facilitator of social interaction, the learning value of social interaction, and the satisfaction of the IEQ demonstrated their influence on the academic result

Modelling hydrological connectivity in burned areas. A case study from South of Spain

Overland flow connectivity depends on the spatio-temporal interactions of hydrological and geomorphic processes as well as on the human footprint on the landscape. This study deals with the modelling of hydrological connectivity in a burned area with different levels of fire severity. Namely, the objectives are to: i) characterize and ii) modelling the pre- (PreF) and post-fire (PostF) scenarios, as well as iii) evaluate the effect of the vegetation changes due to the fire and the initial post-fire management practices (construction of new skid trails and check-dams) on the magnitude and spatial pattern of connectivity. Four post-fire scenarios are simulated: immediately after the fire (PostF1), with new skids and without check-dams (PostF2), with new skids and check-dams and without vegetation recovery (PostF3), and with new skids and check-dams and incipient vegetation cover (PostF4). The study area corresponds to eleven headwater sub-catchments (total area of 329 ha) that cover the entire burned area of the mountain in the West and Southwest facing hillslopes (ca. 200 ha). This site is located in the province of Malaga, South of Spain, and all sub-catchments are disconnected between them. The fire started in 2014, 27 June and lasted two days. The landscape is mainly mountainous, with very steep slopes and marble rocks, Mediterranean climate, and a land use of shrubs and pine forests (pre-fire scenario). Settlements appear at the bottom of the slopes. After the wildfire, land management were carried out in order to remove completely the burned trees and thus new skid trails were built. Then, eleven concrete check-dams and twelve wooded check-dams were built in the main gullies. The different scenarios of linear landscape elements, vegetation cover and modifications on the topography related to the construction of new trails and check-dams were included in the simulations. The IC index of hydrological connectivity was chosen to perform this metric at a spatial resolution of 5 x 5 meters. The analysis of the different spatial patterns and temporal changes was done considering the different levels of fire severity and changes on hydrological connectivity were also analysed at the outlet of each sub-catchment.Universidad de Málaga.

Putting health in all policies: The National Institute for Welfare Enhancement

Welfare is a rather vague term whose meaning depends on ideology, values and judgments. Material resources are just means to enhance people’s well-being, but growth of the Gross Domestic Production is still the standard measure of the success of a society. Fortunately, recent advances in measuring social performance include health, education and other social outcomes. Because “what we measure affects what we do” it is hoped that social policies will change. The movement Health in all policies and its associated Health Impact Assessment methodology will contribute to it. The task consists of designing transversal policies that consider health and other welfare goals, the short term and long-term implications and intergenerational redistributions of resources. As long as marginal productivity on health outside the healthcare system is higher than inside it, efficiency needs cross-sectoral policies. And fairness needs them even more, because in order to reduce social inequalities in health, a wide social and political response is needed. Unless we reduce the well-documented inefficiencies in our current health care systems the welfare states will fail to consolidate and the overall economic wellbeing could be in serious trouble. In this article we sketched some policy solutions such as pricing according to net benefits of innovation and public encouragement of radical innovation besides the small type incremental and market-led innovation. We proposed an independent agency, the National Institute for Welfare Enhancement to guarantee long term fair and efficient social policies in which health plays a central role.Public health policies; Health Impact Assessment; Welfare; Health in All Policies.

Drivers and Impacts of R&D Adoption on Transport and Logistics Services

Actually, technologies and applications in industries are changing via business restructuring, new business models, new knowledge and supply chains. So R&D is not focused primarily on manufacturing industry as it used to be, but on different kinds of industries as logistics and transport (TLS). Nevertheless, the characteristics of the TLS industry determine the introduction of specific R&D solutions accordingly to sectors operations. The objective of this paper is to describe the R&D opportunities in the TLS industry and how managers use them to make their businesses more innovative and efficient. Using the Structure-Conduct-Performance (SCP) model the paper identifies the links between R&D adoption and innovation dynamics. Relating the findings, on the driver’s side there are three points that are worth mentioning: increasing market competition, the relationships of firms interacting with each other and the availability and quality of complementary assets such as employee skills and IT know-how. On the impacts’ side, firms advanced in terms of implementing R&D solutions are more likely to implement organizational changes. Finally, a set of recommendations on how to further improve the continuous innovation in the TLS industry is presented

Classical Tradition in Spain: Some Perspectives from Classical Philology

Se definen conceptos previos relacionados con el estudio de la fortuna de lo clásico y se destacan algunas obras críticas fundamentales para esta disciplina. Se pone de relieve en especial la importancia de la producción de María Rosa Lida de Malkiel como modelo para el estudio de la presencia de lo clásico en la literatura española. Y se analizan, en general y en pasajes concretos, dos obras de la literatura española en relación con su recepción de lo clásico: el Libro de buen amor del Arcipreste de Hita (siglo XIV), ejemplo de recepción medieval, y la Fábula de Faetón del Conde de Villamediana (siglo XVII), ejemplo de recepción barroca. El ingrediente clásico en la obra del Arcipreste proviene mayoritariamente de fuentes intermedias (Pamphilus, Compendium moralium de Geremia da Montagnone, etc.) y es sobre todo de carácter material (elementos doctrinales, morales, tópicos). La fábula mitológica de Villamediana no solo es deudora de lo clásico en su argumento mitológico-ovidiano, sino en su estilo oscuro, que se fundamenta en el latinismo constante y en el recurso a la perífrasis culta y frecuentemente mitológica; estas características de la obra requieren una especial pericia para su correcta edición y glosa.This paper defines previous concepts related to the study of the fortune of the classical and highlights some key critical works to this topic. The importance of María Rosa Lida de Malkiel’s production is brought to light as a model for the study of the presence of the classical in Spanish Literature. Two works of Spanish literature are also analyzed, in general and in specific extracts, according to the relation with their reception of the classical: the Libro del buen amor by Archpriest of Hita (14th century), example of medieval reception, and the Fabula de Faetón by the Count of Villamediana (17th century), example of reception in the Baroque period. The classical element in the Archpriest’s work comes chiefly from intermediate sources (Pamphilus, Compendium Moralium by Geremia da Montagnone, etc.) and is mainly of a material nature (doctrinal, moral, commonplace elements). Villamediana's mythological fable is not only influenced by the classic in its mythological-Ovidean plot, but also in its obscure style, based on the constant Latinisms and on the frequent use of learned and mythological periphrasis; these characteristics of this work demand a special expertise for its correct edition and comment

The supossed vanishing of the body: Political identities, suspicions and variations in the LGBTI+ videogames

En el cruce entre la filosofía, la sociología y los estudios culturales, así como desde una perspectiva LGBTI+, en este artículo se aborda primero la problemática de los cuerpos desde un enfoque filosófico para situarla en la política y en la historia como herramienta de conocimiento. Para después considerar cómo se desarrolla esta problemática en los espacios virtuales, en concreto en tres videojuegos (dos de ellos explícitamente LGBTI+), relacionando la representación de los cuerpos virtuales con la configuración de identidades LGBTI+Crossing Philosophy, Sociology and Cultural Studies, and using a LGTBI+ political approach, in this article we deal with the problematic of the bodies from a philosophical approach to place them in the historical and political field as tools of knowledge. Afterwards, it’ll be considered how to tackle those issues in the virtual space, primarily in three videogames (two of them specifically LGTBI+), and linking the representation of the virtual bodies towards the configuration of LGTBI+ identitie
