Effect of artificial shading on the tannin accumulation and aromatic composition of the Grillo cultivar (Vitis vinifera L.)
2013
Abstract Background White wine quality, especially in warm climates, is affected by sunlight and heat stress. These factors increase the probability that ambering processes will occur and reduce the potential flavour compounds. This study aimed to investigate the effect of sunlight reduction on the accumulation of polyphenolic and aromatic compounds. Results This study was conducted in a commercial vineyard containing V. vinifera L. cv Grillo. Opaque polypropylene boxes (100% shading) and high-density polyethylene (HDPE) net bags (50% shading) were applied at fruit set. The effect of the shaded treatments was compared to the exposed fruit treatment. The shaded treatments resulted in heavier…
Etude de la gouvernance d’une association dans un contexte de fusion
2018
International audience; L’objet de ce travail est d’étudier la gouvernance cognitive au sein d’associations qui ont fusionné. Une étude de cas réalisée au sein d’une association d’aide à domicile permet de mettre en lumière les confrontations entre les différents acteurs et le processus d’apprentissage qui nourrit des adaptations dynamiques et innovantes.
Agder Living Lab: From Ideas to Large-Scale Deployment and Long-Term User Adoption of Inclusive Health Solutions
2016
End-user involvement is a central part in the strategy of public and private organisations to generate user-driven innovative solutions to real-world problems. The Living lab concept is an instrument to create user-centered solutions, with almost 400 recognized in the European Network of Living Labs (ENoLL) since 2006. Living labs cover diverse topics, such as smart-cities, innovative learning and digital health. A national initiative in Southern Norway has funded the Agder Living Lab (ALL) for eHealth, a user-centered innovation environment participated by multisectorial public and private partners. ALL implements a quadruple-helix model represented by citizens, industry, academia and gove…
Mapping nonlinear gravity into General Relativity with nonlinear electrodynamics
2018
We show that families of nonlinear gravity theories formulated in a metric-affine approach and coupled to a nonlinear theory of electrodynamics can be mapped into General Relativity (GR) coupled to another nonlinear theory of electrodynamics. This allows to generate solutions of the former from those of the latter using purely algebraic transformations. This correspondence is explicitly illustrated with the Eddington-inspired Born-Infeld theory of gravity, for which we consider a family of nonlinear electrodynamics and show that, under the map, preserve their algebraic structure. For the particular case of Maxwell electrodynamics coupled to Born-Infeld gravity we find, via this corresponden…
NATURALLY AVAILABLE SOLUTIONS FOR BUILDING NEW METABOLIC TERRITORIES
2021
Building new metabolic territories is a proactive way of responding to the challenges and precariousness of the contemporary city. Byintegrating solutions inspired by new scientific advances in urban ecology, cities are able to address some of the environmental threats. Many European cities are implementing alternative nature-based solutions to protect their health and tackle water scarcity, land consumption and climate change, to increase citizens' well-being. Wellbeing and health (Agenda 2030) are the most important analytical parameters for measuring the results and impacts of environmental project actions. With this in mind, the study presents a "nature-action" project hypothesis for wh…
Valoración de los cambios de los aniones orgánicos que participan en el equilibrio ácido-base al introducir un regimen de biofiltración sin acetato
2011
VALORACIÓN DE LOS CAMBIOS DE LOS ANIONES ORGÁNICOS QUE PARTICIPAN EN EL EQUILIBRIO ÁCIDO-BASE AL INTRODUCIR UN REGIMEN DE BIOFILTRACIÓN SIN ACETATO. La corrección de la situación de acidosis metabólica común a la insuficiencia renal crónica es uno de los objetivos prioritarios del tratamiento de sustitución dialítico. La diálisis es capaz de producir cambios en el perfil metabólico dependientes de la modalidad y del líquido empleados. Realizamos un estudio con 22 pacientes estables en programa de hemodiálisis que se sometieron de forma cruzada a dos modalidades de hemodiafiltracion una con 34 mmol/l de bicarbonato y 3 mmol/l de acetato (HDF) y la otra biofiltración sin acetato (AFB). Según …
Halloysite Nanotubes: Smart Nanomaterials in Catalysis
2022
The use of clay minerals as catalyst is renowned since ancient times. Among the different clays used for catalytic purposes, halloysite nanotubes (HNTs) represent valuable resources for industrial applications. This special tubular clay possesses high stability and biocompatibility, resistance against organic solvents, and most importantly be available in large amounts at a low cost. Therefore, HNTs can be efficiently used as catalysts themselves or supports for metal nanoparticles in several catalytic processes. This review reports a comprehensive overview of the relevant advances in the use of halloysite in catalysis, focusing the attention on the last five years.
Hot Impression Die Forging Process: An Approach to Flash Design for Tool Life Improvement
2005
In impression die forging the role of the flash geometry is fundamental since a proper design of the flash land strongly influences both the complete die filling and the die wear (i.e. the die life and the related costs). In this paper an integrated approach between numerical simulations and statistical tools was developed with the aim to optimize flash thickness in order to reduce die wear and to minimize material wasting. As wear is regarded, an analytical model depending on sliding velocity, temperature, die hardness and contact pressure was utilized during the numerical simulations of the process in order to reach a wear evaluation for different values of the flash design variables. Thu…
Pomological, Sensorial, Nutritional and Nutraceutical Profile of Seven Cultivars of Cherimoya (Annona cherimola Mill)
2020
In this work, the food quality of four international (Campas, Chaffey, Fino de Jete and White) and three local (Daniela, Torre1 and Torre2) cultivars of Cherimoya (Annona cherimola Mill) was investigated. With this aim, pomological traits, sensorial attributes, physiochemical parameters (pH, total soluble content and total acidity), nutritional composition (macro- and micro-nutrients) and nutraceutical values (bioactive compounds, radical scavenging and antioxidant properties) were evaluated. Among the seven observed cultivars, Fino de Jete was identified as the best, not only for its commercial attributes such as pomological traits and physiochemical values, but also for its nutritional co…
Acceptance of Online Health Services for Self-Help in the Context of Mental Health : Understanding Young Adults Experiences
2018
This paper explores the understanding of the acceptance of online health services from a selfhelp perspective in the context of mental health. By examining the experiences of young adults, this paper develops a framework to leverage the current understanding of the factors that would support the acceptance and use of these types of services. To this end, a multidisciplinary perspective incorporating knowledge from the service marketing, health, and information systems literature is used. The results suggest that the production of online services that are meant for self-help purposes necessitates a focus on the acceptance of technology and, more importantly, instrumental value creation, as t…
