Pannello precompresso di vetromattoni assemblati a secco per la realizzazione di involucri traslucidi
2012
L’invenzione riguarda la realizzazione di un pannello di vetromattoni montati “a secco” -da impiegare per la realizzazione di involucri edilizi traslucidi anche nel caso di edifici alti- che è in grado di rispondere adeguatamente alle sollecitazioni orizzontali (quali quelle dovute a vento e sisma) grazie all’applicazione della tecnica della precompressione mondirezionale. Per offrire una risposta ai limiti imposti dalla tecnica di assemblaggio tradizionale dei vetromattoni (“ad umido”), l’applicazione della precompressione consente, infatti, di dare ai pannelli preassemblati “a secco” una rigidezza adeguata anche in direzione normale al loro piano di posa, sfruttando le buone caratteristic…
Demanda y escalas de equivalencia: evidencia para España
2004
El objetivo de este trabajo es plantear teoricamente el estudio de los efectos que los hijos imponen sobre las decisiones de demanda del hogar (los costes de los hijos, por ejemplo), tanto desde el punto de vista dinamico como estatico, utilizando el concepto de separabilidad demografica. Ademas, establecer la relacion entre ambos conceptos teoricos nos permitira investigar el grado de imprecision o el sesgo que se produce cuando se utiliza una medida estatica frente a una medida intertemporal. El ejercicio empirico se lleva a cabo utilizando un panel de datos extraido de la Encuesta Continua de Presupuestos Familiares, que cubre el periodo 1985-1995. Se estima un sistema de demanda Marshal…
Creatine consumption and liver disease manifestations in individuals aged 12 years and over
2022
Despite the overwhelming safety evidence concerning creatine intake in various settings, there is still incomplete information whether dietary creatine affects liver health at the population level. The main aim of this cross-sectional population-based study was to evaluate the association between creatine intake through regular diet and liver disease manifestations, including liver fibrosis and hepatic steatosis, among individuals aged 12 years and over, using open-source data from the 2017–2018 U.S. National Health and Nutrition Examination Survey (NHANES). A total of 9254 male and female participants of all ages were included in the 2017–2018 NHANES round. We extracted data from the total…
Thermal conductivity measurement of insulating innovative building materials by hot plate and heat flow meter devices: A Round Robin Test
2019
Abstract The characterization of thermal insulation properties of construction materials represents a fundamental step on the building insulation assessment. In recent years innovative materials have been introduced in the market to fulfill the continuously growing requirements of energy saving and sustainability, and their performance is not so reliable and mature as it happens for traditional insulators. The work presents a Round Robin Test realised among six European laboratories hosting hot plates devices to measure the thermal conductivity of four different materials: aerogel, vacuum insulation panels, polystyrene and birch wood fibre insulation boards. After the definition of the comm…
Nanofilm metal layers as vacuum quality sensors
2010
Abstract A monitoring device for vacuum quality is realized by lowest cost single use oxygen sensors for vacuum insulation panels. They use the pressure dependence of oxide layer growth thickness on electrically measured metal nanofilms. These films were manufactured by e-beam evaporation, characterized in terms of resistance change with subsequent modeling of underlying mechanisms.
Visual Search Performance Depending on Target-Distractor Difference on Volumetric Display and Flat Panel Display
2019
The search items were demonstrated on the volumetric display and flat panel display. In contrast to the correct response rate, the search time and number of interactions were considerably affected by the type of visualization.
Sistema automatico di protezione e di sicurezza per sistemi fotovoltaici.
2016
Sistema automatico di protezione e di sicurezza per sistemi fotovoltaici. The aim of the invention is to define a safety device for workers and/or operators in photovoltaic systems (PV) both during interventions of normal use (maintenance) and during emergency condition (fire, etc.).Thus, the permanence of continuous voltage along the stretch-line included between the inverter and the panel is still a problem that has not found solution. The scientific-technical objectives of the invention can be considered in the context of the evolving technology of PV system providing great security of the system itself. The system consists of a device, which prevent irradiation of the solar rays from th…
Combining Olfactory and Gustatory Clues in the Judgment of Aging Potential of Red Wine by Wine Professionals
2010
International audience; The study was aimed at determining the relative importance of olfactory and gustatory information for the vin de garde concept, which refers to wine that is intended for aging. First, the study investigated how olfactory information contributed to the assessment of the aging potential of young wine. Burgundy wine professionals categorized 26 red wines (vintage 2005) according to their aging potential in two experimental conditions: orthonasal evaluation and overall evaluation. Second, the aromatic notes associated with wines perceived with an aging potential were examined. A trained descriptive panel described the odor of the 26 red wines to determine whether the win…
In search of the taste of terroir: a challenge sensory science
2020
International audience; The definition of terroir has evolved throughout history, from something clearly negative in the XVIth-XVIIIth century to a complex multi-parametric construct with positive connotations but also with many scientific unknowns. Terroir has always been linked more or less explicitly to the sensory properties of the resulting products. Wine consumers have little access to objective terroir information and even if they had, it would be very difficult for them to interpret in terms of wine quality. In Europe, the proxy for terroir is the Protected Designations of Origin (PDO) system, which is what consumers have come to know. According to INAO “It is the notion of soil (te…
Climate and agriculture: empirical evidence for countries and agroecological zones of the Sahel
2022
International audience; ow heterogenous is the impact of climate change across space and the type of agricultural production? In this paper, we investigate the relationship between climate change and variability, measured by temperature and rainfall, and agricultural production at the country and agroecological zone levels of the Sahel. We consider a crop production index and five cereals (maize, millet, sorghum, wheat and rice). Based on an original climate database and an agricultural production function estimated for the period 1961–2016, we show that average rainfall and temperature during the growing season indeed have highly heterogeneous effects on agricultural production, depending …
