Influence of a thin horizontal weak layer on the mechanical behaviour of shallow foundations resting on sand
2021
The presence of minor details of the ground, including soil or rock masses, occurs more frequently than what is normally believed. Thin weak layers, shear bands, and slickensided surfaces can substantially affect the behaviour of foundations, as well as that of other geostructures. In fact, they can affect the failure mechanisms, the ultimate bearing capacity of footings, and the safety factor of the geotechnical system. In this research, numerically conducted through Finite Element Code Plaxis 2D, the influence of a horizontal thin weak layer on the mechanical behaviour of shallow footings was evaluated. The obtained results prove that the weak layer strongly influences both the failure me…
A generalized model of elastic foundation based on long-range interactions: Integral and fractional model
2009
The common models of elastic foundations are provided by supposing that they are composed by elastic columns with some interactions between them, such as contact forces that yield a differential equation involving gradients of the displacement field. In this paper, a new model of elastic foundation is proposed introducing into the constitutive equation of the foundation body forces depending on the relative vertical displacements and on a distance-decaying function ruling the amount of interactions. Different choices of the distance-decaying function correspond to different kind of interactions and foundation behavior. The use of an exponential distance-decaying function yields an integro-d…
ECO Experts’ consensus on establishing renal cancer healthcare quality measures in Spain.
2020
220 Background: The ECO Foundation (Excellence and Quality in Oncology) proposes to establish a set of healthcare quality measures (including indicators and standards) for the diagnosis, treatment and follow-up of renal cancer in Spain which all healthcare professionals involved can assume, being suitable for implementation in the continuous improvement process of our healthcare system. Methods: a) International literature review on the quality of healthcare in renal cancer; b) multidisciplinary driving group (9 oncologists with expertise in renal cancer plus 2 methodologists) to identify and choose possible quality measures to be applied in Spain; c) global evaluation of the relevance of …
Non-clinical needs of cancer patients in Spain under different perspectives: A comparative study.
2019
e18266 Background: Patients with cancer and their caregivers express unmet needs beyond the clinical approach to cancer. The ECO Foundation (Quality and Excellence in Oncology) and the Spanish Association Against Cancer (AECC) have promoted a qualitative research study with the objective to compare the perceptions of newly diagnosed and 2-3 years after diagnosis cancer patients, caregivers, oncologists, nurses and social workers in relation to a set of non-clinical needs expressed by cancer patients and caregivers, and to obtain concrete and feasible proposals for improvement aimed at satisfying these needs. Methods: A multidisciplinary group of experts developed a questionnaire containing…
‘I changed my life’s course’ : The impact of the Helsingin Sanomat Foundation fellowship on the career path of a journalist
2017
This study focuses on the fellowship program of Helsingin Sanomat Foundation, which has sent a hundred mid-career journalists from Finland to study abroad at prominent universities. Based on two surveys, one on the fellows (n = 45) and one on a control group (n = 52), the article discusses the impact the fellowship education has on the journalists and their careers. The surveys are complemented with in-depth interviews of 10 fellow journalists. The results are discussed in the context of protean career concept, and they indicate that the fellowship period has a notable positive impact on the career of an individual journalist, but a contradictory impact on the journalist’s home organizatio…
Centrifuge tests on strip footings on sand with a weak layer
2017
Tests on small-scale physical models of a strip footing resting on a dense sand bed containing a thin horizontal weak soil layer were carried out at normal gravity (1 g ). The results, reported in a companion paper, point out that the weak layer plays an important role in the failure mechanism and the ultimate bearing capacity of the footing if it falls within the ground volume relevant to the behaviour of the sand–footing system. The same problem was also investigated by means of centrifuge tests on reduced-scale models at 25 g and 40 g . The results of these tests, reported and discussed in this paper, confirm that failure mechanisms are governed substantially by the presence of the weak…
Luminescence dating applied to Saint-Irénée’s church (Lyon, France)
2014
The aim of the study presented here is to propose a new view on the chronology of early medieval buildings in Europe and on the related building modes. If several studies have proved the efficiency of this multidisciplinary process, the case of St. Irenee’s church is very representative of the contributions of such an approach. This church is one of the oldest witnesses of the Christianization in Lyon, capital city of Gauls, and of its evolution under the aegis of Burgonds. However the small number of preserved remains of its early states has shown uncertainties in the interpretation of the chronology of the building use. There are two possibilities: is it the monument described by Gregory …
The identity type weak factorisation system
2008
We show that the classifying category C(T) of a dependent type theory T with axioms for identity types admits a non-trivial weak factorisation system. We provide an explicit characterisation of the elements of both the left class and the right class of the weak factorisation system. This characterisation is applied to relate identity types and the homotopy theory of groupoids.
Towards a methodological toolset for the psycholinguistics of translation
2021
Abstract The manuscript provides readers with a basic methodological toolset for experimental psycholinguistic studies on translation. Following a description of key methodological concepts and the rationale behind experimental designs in psycholinguistics, we discuss experimental paradigms adopted from bilingualism research, which potentially constitute a methodological foundation for studies investigating the psycholinguistics of translation. Specifically, we show that priming paradigms possess several inherent advantages which make them particularly suitable for research on translation. The manuscript critically discusses key methodological problems associated with such paradigms and ill…
Analysis of block random rocking on nonlinear flexible foundation
2020
Abstract In this paper the rocking response of a rigid block randomly excited at its foundation is examined. A nonlinear flexible foundation model is considered accounting for the possibility of uplifting in the case of strong excitation. Specifically, based on an appropriate nonlinear impact force model, the foundation is treated as a bed of continuously distributed springs in parallel with nonlinear dampers. The statistics of the rocking response is examined by an analytical procedure which involves a combination of static condensation and stochastic linearization methods. In this manner, repeated numerical integration of the highly nonlinear differential equations of motion is circumvent…
