Vegetation growth parameters and leaf temperature: Experimental results from a six plots green roofs' system
2016
Abstract The paper provides a contribution for populating database of three physical parameters needed to model energy performance of buildings with green roofs: “coverage ratio” ( σ f ), leaf area index (LAI) and leaf temperature ( T f ). On purpose, six plant species were investigated experimentally: Phyla nordiflora, Aptenia lancifolia , Mesembryanthenum barbatus , Gazania nivea, Gazania uniflora , and Sedum . Proper ranges of the cited parameters have been found for each species. The here indicated ranges of σ f values refer to different growth levels of the species in the same lapse of time, that is four months. Single measured LAI values are also reported for the same plants. As for t…
Impact of building automation control systems and technical building management systems on the energy performance class of residential buildings: An …
2014
Abstract The paper focuses on the evaluation of the impact on residential buildings of building automation control (BAC) and technical building management (TBM) systems. This work shows how the control, monitoring and automation functions considered by the European Standard EN 15232 can considerably influence the energy performance of a single-family test house and, consequently, its energy performance class. The study puts into evidence that the benefit that can be drawn from the installation of BAC and TBM systems depends on the type of technical appliances in the household and on the starting energy performance class. Finally, the economic impact due to the introduction of BACS or TBM fu…
Development and validation of the neighborhood environment walkability scale for youth across six continents
2019
Abstract Background The IPEN International Physical Activity and Environment Network Adolescent project was conducted using common study protocols to document the strength, shape, and generalizability of associations of perceived neighborhood environment attributes with adolescents’ physical activity and overweight/obesity using data from 15 countries. Countries did not use identical versions of the Neighborhood Environment Walkability Scale for Youth (NEWS-Y) to measure perceived neighborhood environment attributes. Therefore, this study derived a measurement model for NEWS-Y items common to all IPEN Adolescent countries and developed a scoring protocol for the IPEN Adolescent version of t…
Zinc-blende AlN and GaN under pressure: structural, electronic, elastic and piezoelectric properties
2004
In this paper we report a theoretical study of the structural, elastic, electronic and piezoelectric properties of zinc-blende AlN and GaN under the pressure effect. The study is focused on the first-principles all electron full-potential augmented plane wave plus local orbitals calculations within the density-functional theory. The results of bulk properties, including lattice constants, bulk modulus and derivatives and band structures are obtained and compared using both the local density approximation (LDA) and the generalized gradient approximation (GGA) for the exchange-correlation functional. We find that the GGA does not give a significant improvement over LDA. We also report calcula…
On the hyperporous non-linear elasticity model for fusion-relevant pebble beds
2010
Abstract Packed pebble beds are particular granular systems composed of a large amount of small particles, arranged in irregular lattices and surrounded by a gas filling interstitial spaces. Due to their heterogeneous structure, pebble beds have non-linear and strongly coupled thermal and mechanical behaviours whose constitutive models seem limited, being not suitable for fusion-relevant design-oriented applications. Within the framework of the modelling activities promoted for the lithiated ceramics and beryllium pebble beds foreseen in the Helium-Cooled Pebble Bed breeding blanket concept of DEMO, at the Department of Nuclear Engineering of the University of Palermo (DIN) a thermo-mechani…
Empirical molecular dynamics study of structural, elastic and thermodynamic properties of zinc-blende-like SiGe compound
2004
Abstract A three-body potential coupled with a molecular-dynamics method is used to calculate structural and thermodynamic properties of the hypothetical IV–IV compound SiGe in zinc-blende phase. A good agreement between the calculated and theoretical values of the lattice constant, the bulk modulus and its derivative, and the cohesive energy is obtained. We also compute the elastic constants, Debye temperature, lattice thermal expansion, and the specific heat. We investigate also, the structural properties of SiGe when rock-salt phase appears.
Construal Level Theory - Eine Theorie für die Grenzenlose Unternehmung? (Construal Level Theory - A Theory for the Boundaryless Organization?)
2010
Der Umgang mit Distanz ist eine Kernaufgabe grenzenloser Unternehmen. Trotz der grosen praktischen Relevanz von Distanz fur Organisationen und obwohl bereits empirische Befunde zu den Auswirkungen von Distanz auf organisationales Verhalten vorliegen, ist das theoretische Konzept der Distanz nur unzureichend in die Organisationstheorie und -forschung integriert. Der vorliegende Artikel bietet eine individuumzentrierte Perspektive auf den Umgang mit Distanz in verteilt arbeitenden, insbesondere virtuellen, Organisationen und Teams. Die Construal Level Theory ist eine sozial-kognitive Theorie, die sich in besonderer Weise zur Erklarung und Vorhersage der Auswirkungen von wahrgenommener Distanz…
Enthalpies of solution and dilution of butanol and pentanol in dodecyltrimethylammonium bromide micellar solutions
1987
The enthalpies of solution and of dilution of 1-butanol and 1-pentanol were measured in micellar solutions of dodecyltrimethylammonium bromide by systematically changing the concentration of alcohols and surfactant. The enthalpies of solution at infinite dilution of alcohols at each surfactant concentration were evaluated from a linear plot. This quantity increases with surfactant concentration (up to 0.8m) with a curvature which depends on the alcohol alkyl chain length. The difficulties arising for a quantitative treatment of both the enthalpies of dilution and of solution at finite alcohol concentrations are discussed. The dependence on the surfactant concentration of the standard enthal…
La reconstrucción de la iglesia de san Juan de Elche y otras empresas neobizantinas de Serrano Peral
2016
Se lleva a cabo el estudio de la reconstrucción de la iglesia San Juan Bautista de Elche por Serrano Peral, a partir del análisis de los documentos custodiados en el Archivo General de la Administración del Estado correspondientes a la Junta Nacional de Reconstrucción de Templos Parroquiales, en los que se ponen de manifiesto dos modos de entender la arquitectura por parte de un mismo autor: un primer proyecto, dentro de las características acciones reconstructivas de la posguerra, y un segundo, enmarcado en los cambios experimentados por la arquitectura española a partir de los años 50, ejemplificadores del quehacer polifacético del arquitecto ilicitano y en el que se destaca su peculiar e…
