Agujero Transverso Bipartito en población rural del siglo XVII y en poblablación actual
2015
INTRODUCCIÓN La columna cervical se diferencia claramente de la región torácica y lumbar, tanto en su anatomía como en su biomecánica (Kapandji IA, 2007). Asimismo, la región cervical debe conciliar su gran movilidad con su papel clave en el paso de estructuras vasculares y nerviosas relacionadas con la región craneal (Gray H, 1989; Das, S et al, 2005; Drake RL et al, 2010; White TD et al, 2011). En este sentido, entre los rasgos anatómicos distintivos de las vértebras cervicales, se encuentra un orificio en las apófisis transversas, denominado foramen transverso, a través del cual asciende la arteria vertebral (White TD et al, 2011; Moore KL et al, 2013). Con respecto a los diámetros anter…
Diorganotin(IV) complexes ofD-galacturonic acid: solid-state and solution-phase structural study
2003
Three diorganotin(IV) complexes of D-galacturonic acid (H2GalA; R = Me, n-Bu, Ph), two of which are new derivatives (R = Me, Ph), have been synthesized and their solid-state and solution-phase investigated by IR, Mossbauer, 1H, 13C and 119Sn NMR spectroscopy. The FTIR data suggest that H2GalA, in the dialkyltin derivatives, behaves as a dianionic ligand, coordinating the tin(IV) atom through an ester-type carboxylate and deprotonated alcoholic hydroxo groups, whereas a bridging carboxylate occurs in the diphenyltin(IV) complex. Octahedral and trigonal bipyramidal local geometries on tin(IV) atoms are proposed for dialkyltin(IV)GalA and diphenyltin(IV)GalA complexes respectively on the basis…
Performance Analyses of Innovative Glassblocks for BIPV
2014
The paper illustrates the results of the performance analyses conducted on an innovative glassblock integrated with 3rd generation dye-sensitized solar cells, designed for enabling the construction of translucent and sustainable building envelopes. The analyses encompass the simulation of both thermal and optical performance referring to different configurations of the PV-integrated glassblock, showing the results obtained by using two different software tools: Comsol Multiphysics and WINDOW. The configurations may differ, for example, because of the position of the module inside the glassblock, the type of dye-sensitized solar module used (composition, transparency, design), and glassblock…
Many-body Green's function theory for electron-phonon interactions: ground state properties of the Holstein dimer
2015
We study ground-state properties of a two-site, two-electron Holstein model describing two molecules coupled indirectly via electron-phonon interaction by using both exact diagonalization and self-consistent diagrammatic many-body perturbation theory. The Hartree and self-consistent Born approximations used in the present work are studied at different levels of self-consistency. The governing equations are shown to exhibit multiple solutions when the electron-phonon interaction is sufficiently strong whereas at smaller interactions only a single solution is found. The additional solutions at larger electron-phonon couplings correspond to symmetry-broken states with inhomogeneous electron de…
Analysis of Electrical Loads and Strategies for Increasing Self-Consumption with BIPV Case study : Skarpnes Zero-Energy House
2017
Master's thesis Renewable Energy ENE500 - University of Agder 2017 At Skarpnes village (Southern Norway), the houses as zero energy buildings (ZEB) are installed with Building Integrated Photovoltaic (BIPV) systems, and these houses are not containing smart control of equipments. The aim of such buildings is that the amount of electrical energy produced is the same as that consumed in the buildings on an annual basis. In this thesis, the main objective is to analyse the methods for increasing self -consumption in BIPV, by minimizing the cost of purchasing electricity from the grid at time with no PV production, and maximizing the utilization of solar PV generated power, which reduces the po…

Kestääkö ääni? : laulunopetuksen vaikutus opettajaksi valmistuvien äänen laatuun ja ilmaisuun
2017
The aim of this study was to investigate how regular singing lessons and deliberate practice impact future teachers’ voice quality and their expression in speech and singing. Previous research about teachers’ speaking voice has shown that kindergarten teachers and classroom teachers are at high risk of showing symptoms or developing disorders, which weaken their effectiveness of expression. The study is qualitative and experimental and it includes longitudinal vocal education, which lasted one academic year. This thesis was approached theoretically through existential phenomenology with a holistic conception of man. Data was gathered from eleven subjects and divided into three research grou…
Inequality of Spanish household expenditure for the 2006-2016 period- are we converging?
2019
The depth and persistence of the Great Recession that started in 2008 had a considerable impact on income distribution and inequality. Therefore, studies of living standards and evolution of income inequality are trend topics nowadays. Our goal was to estimate the impact of the economic crises on household expenditure and the trends and evolution of regional inequality. We applied our analysis to the Spanish case based on Household Budget Survey data from Instituto Nacional de Estadística (INE, the National Statistics Institute) and the period of eleven years between 2006 and 2016. A model that showed good results in modelling income was the biparametric gamma model, which is further very u…
Azonia spiro polyaza macrocycles containing biphenyl subunits as anion and cation receptors
2011
Abstract The reaction of N-Boc triprotected cyclam with bis(chloromethyl)biphenyl followed by the corresponding deprotection of the nitrogen atoms allows the preparation of receptor 3 containing an azonia spiro subunit. This receptor shows slightly increased basicity than cyclam, in particular for the formation of the appropriate triply charged species as a consequence of the reduced capacity of the structure present in 3 to stabilize the species with lower protonation degrees through the formation of intramolecular hydrogen bonds. The properties of 3 as a receptor for Cu2+ and Zn2+ and the anions derived from PO 4 3 − ( Pi ) , P 2 O 7 4 − ( PPi ) , P 3 O 10 5 − ( TPP ) and ATP have been st…
4,4′-bis(dimethylamino)biphenyl containing binding sites. A newfluorescent subunit for cation sensing
2002
The emission behaviour of the 4,4′-bis(dimethylamino)biphenyl subunit covalently attached to aza-crown ethers is studied. Some new ligands have been synthesised in order to test the properties of this new fluorophore. The fluorescence of these new ligands and some other compounds previously described has been studied in acetonitrile in the presence of Ni2+, Cu2+, Zn2+, Hg2+, Pb2+, Cd2+ and also in the presence of some alkali and alkaline-earth cations.
