Experiences of perinatal women and public healthcare providers in a community affected by the great east Japan earthquake and tsunami: Concerns that …
2020
Abstract Particular support needs of perinatal women in a disaster have been difficult to grasp through preexisting quantitative epidemiological studies. This study aimed to extract concerns that must be considered for perinatal women's mental healthcare in postdisaster settings based on lessons from the Great East Japan Earthquake. Narrative messages regarding protective and risk factors for mothers' mental health from a representative population of mothers who had given birth and all official maternal caregivers, in a coastal town devastated by the catastrophe were subjected to qualitative analyses. Eight concerns were extracted as specific support needs: (1) improve information pathways,…
Benchmark study of undrained triaxial testing of Opalinus Clay shale: Results and implications for robust testing
2021
Triaxial testing of argillaceous rocks and shales is significantly more challenging than conventional rock mechanical testing. The challenges are mainly related to the very low permeability of these geomaterials, and their sensitivity to exposure of atmosphere and brines, which induces variations of water content, suction and effective stress. There are currently no international standards to guide service laboratories for robust testing procedures for shales. A benchmark study of undrained triaxial testing was therefore initiated with three leading service laboratories in shale testing, performing 13 tests and using two different methods of establishing sample saturation prior to deformati…
A Top-Down Approach Based on the Circularity Potential to Increase the Use of Reclaimed Asphalt
2023
Resource depletion and climate change, amongst others, are increasingly worrying environmental challenges for which the road engineering sector is a major contributor. Globally, viable solutions that comply with the principles of circular economy (CE) are being investigated that can replace conventional asphalt mixtures in a post-fossil fuel society. The use of reclaimed asphalt (RA) is a widely used and well-established method to reduce the environmental and economic impacts of asphalt mixtures while increasing their circularity. However, RA’s market supply and demand have not yet been systematically analyzed and established. Moreover, the actual circularity potential and the opportu…
User behavior in Smart and Sustainable Offices (SSO)
2017
Smart and Sustainable Offices (SSO) require synergies between technologies and users behaviors. The sociotechnical approach considers users’ motives, attitudes, cognitions and behaviors when designing work environments. This note will describe those phenomena in office environments. It will also present a set of tools to assess those phenomena and will provide guidelines to improve them.
Local vs. National Environmental Spending: A Stochastic Frontier Analysis
2012
This work studies the impact of public environmental spending in a fiscal federalist framework. The main question is studying when the centralization of this public economic function is welfare improving. Applying the Stochastic Frontier Approach (SFA) on Italian, Portuguese and Slovakian data, the paper tries to test this issue. Our results highlight the superiority of centralized environmental spending with respect to the decentralization of this particular public good.
Technical issues in beginning violin: an exploratory study in the classroom with 4-5 years old preschoolers
2018
Conocer los errores técnicos de los alumnos en la enseñanza de la música puede ser de gran ayuda en la planificación de la enseñanza instrumental en sus fases iniciales. Esto es particularmente valioso en el trabajo con alumnado de 4-5 años. Este estudio explora esta cuestión mediante una Investigación-Acción realizada con 11 estudiantes voluntarios de dichas edades. A lo largo de 30 sesiones individuales de 30 minutos, se recogieron datos mediante observación participante realizada por el profesor en una Escuela Municipal de Música, comparándose dos aproximaciones didácticas de iniciación al violín. Una aproximación se centró en el manejo de la mano derecha (aproximación MD), introduciendo…
Normal pressures and frictional tractions on shallow conical hopper walls after concentric filling: Predictions and experiments
2013
Author's version of an article in the journal: Chemical Engineering Science. Also available from the publisher at: http://dx.doi.org/10.1016/j.ces.2012.11.028 A silo with a shallow hopper is designed to achieve the required silo capacity when the headroom available is limited, provided that the issue of segregation of stored particulate solids is not a problem. Several analytical models have been proposed to try to predict the design loads for such shallow silo hoppers to guarantee their structural integrity. In this study, a novel finite element analysis has been conducted to explore the development of pressures and tractions on the wall of a full scale shallow hopper when it is filled wit…

Stability of Embankments Resting on Foundation Soils with A Weak Layer
2021
The presence of weak layers in geotechnical systems, including soil or rock masses, both natural and man-made, is more frequent than is normally believed. Weak layers can affect both failure mechanisms, in drained and in undrained conditions, as well as in static and seismic conditions, and the safety factor. In the present study, conducted numerically using the finite-element method (FEM) Plaxis 2D code, the influence of a horizontal thin weak layer on stress and strain distribution, on failure mechanisms and on the overall stability of an embankment was evaluated. The results obtained prove that when the weak layer is located at a significant depth from the foundation plane, the failure m…
Toward the Development of Load Transfer Efficiency Evaluation of Rigid Pavements by a Rolling Wheel Deflectometer
2020
The jointed rigid pavement is currently evaluated by the Falling weight deflectometer which is rather slow for the testing of the jointed pavements. Continuous nondestructive evaluation of rigid pavements with a rolling wheel deflectometer can be used to measure the load transfer and is investigated. Load transfer is an important indicator of the rigid pavement&rsquo
