One-dimensional heterogeneous solids with uncertain elastic modulus in presence of long-range interactions: Interval versus stochastic analysis
2013
The analysis of one-dimensional non-local elastic solids with uncertain Young's modulus is addressed. Non-local effects are represented as long-range central body forces between non-adjacent volume elements. For comparison purpose, the fluctuating elastic modulus of the material is modeled following both a probabilistic and a non-probabilistic approach. To this aim, a novel definition of the interval field concept, able to limit the overestimation affecting ordinary interval analysis, is introduced. Approximate closed-form expressions are derived for the bounds of the interval displacement field as well as for the mean-value and variance of the stochastic response.
New trends in science education
1996
I intend to review the main contributions from the impressive developments made in science education research during the last decade. These developments have made the construction of a coherent body of knowledge possible allowing us to expect a significant improvement in the science teaching/learning process. I shall refer, in particular, to the new trends in science education research, both in the domain of science learning and science teacher‐training.
Facility management, outsourcing and contracting overview
2009
The discipline of facility management has basically originated from the experience of the field and most of the business models are driven from the American market. The majority of surveys agree that organizational objectives vary according to different business environments. The link between a given company and its facility management department has been studied in details with a widespread agreement on the importance of tailoring to the specific context the facility management organizational model and the approach to the relationships with suppliers. In Europe two Technical Committees of the Comite Europeen de Normalisation (CEN) are currently adding to the body of knowledge terminologies…
A Non-Reductionist Physiologism: Nietzsche on Body, Mind and Consciousness
2013
This paper addresses the following questions from the point of view of Nietzsche’s philosophy: What is the mind, and which kind of relationship does it hold to the body? Accordingly, the aim of this paper is to show that Nietzsche’s philosophy suggested a view of the mind that allows to outline an alternative stance to both mentalism and physicalism, as well as to both dualism and reductionism. It is argued that Nietzsche’s rehabilitation of the body as the specific seat of the mind in opposition to the Cartesian supremacy of the Ego still is of a great interest for contemporary philosophy, since it is not equivalent either to a reversed form of Cartesian dualism or to a physicalist reducti…
Developmental differences in the uterus of Fasciola hepatica between livestock liver fluke populations from Bolivian highlands and European lowlands
2001
A morphometric study of the uterus area (UA) of Fasciola hepatica adults was carried out with the aid of a computer linked to a stereomicroscopic 3CCD colour video camera using image analysis software. The UA of adult liver flukes found in naturally infected sheep, cattle and pig from the endemic human fascioliasis zone of the northern Bolivian Altiplano highlands was compared with that of flukes found infecting sheep and cattle from Valencia, Spain and cattle from Corsica, France (collectively, European lowlands). Liver fluke UA was examined using an allometric model. A comparison of the allometry of the liver fluke UA in different host species from Bolivia revealed no significant differen…
The Bologna Process in France : Origin, Objectives and Implementation
2008
05010; In this paper, we will try to show why the evolution of the French higher education system has led to a deadlock and a deteriorating ranking on the world scene, how the new scheme has been effectively and rapidly adopted, but unfortunately, why this adoption has failed to achieve the initial objectives of transforming the French system into a more competitive one.
Comparison of various CI treatments for the description of potential curves for the lowest three states of O2
1972
Abstract Various ab initio CI treatments are reported for the 3 Σ − g , 1 Δ g and 1 Σ + g states of O 2 with particular emphasis on the agreement obtained between calculated and experimental results for binding energies and bond distances of these species and also for transition energies between them. The utility of off-center s and p gaussians in describing the bonding process is stressed and the possibility of optimizing the configurations used in the calculations at each internuclear distance is considered.
Bone regeneration at extraction sockets filled with leukocyte-platelet-rich fibrin: An experimental pre-clinical study
2022
We aimed to histomorphometrically evaluate the effects of Leucocyte-Platelet-Rich Fibrin (L-PRF), with and without the combination of a bone grafting material, for alveolar ridge preservation using an in vivo canine model. Seven dogs (Female Beagles, ~18-month-old) were acquired for the study. L-PRF was prepared from each individual animal by drawing venous blood and spinning them through a centrifuge at 408 RCF-clot (IntrasSpin, Intra-Lock, Boca Raton, FL). L-PRF membranes were obtained from XPression fabrication kit (Biohorizons Implant Systems, Inc., AL, USA). A split mouth approach was adopted with the first molar mesial and distal socket defects treated in an interpolated fashion of th…
Intraoral onlay block bone grafts versus cortical tenting technique on alveolar ridge augmentations: a systematic review
2021
To review systematically the bone gain and superficial resorption rate of the onlay block bone grafts versus the cortical tenting technique, as well as secondarily study the postoperative complications, implant survival and success rates, and peri-implant marginal bone loss. Following the recommended methods for systematic reviews and meta-analyses (PRISMA), an electronic search was performed in the PubMed (MEDLINE), EMBASE and the Cochrane Library of the Cochrane Collaboration (CENTRAL) databases to identify all relevant articles published up to March 2021 on onlay block bone grafts and cortical tenting technique. Eighteen papers complied with the inclusion criteria. In onlay grafts, the v…
Numerical simulations on periprosthetic bone remodeling: a systematic review
2021
Abstract Background and objective The aim of the present study was to review the literature concerning the analysis of periprosthetic bone remodeling through finite element (FE) simulation. Methods A systematic review was conducted on 9 databases, taking into account a ten-year time period (from 2009 until 2020). The inclusion criteria were: articles published in English, publication date after 2009, full text articles, articles containing the keywords both in the abstract and in the title. The articles were classified through the following parameters: dimensionality of the simulation, modelling of the bone-prosthesis interface, output parameters, type of simulated prosthesis, bone remodeli…
