Experimental Procedures of Accelerated Aging and Evaluation of Effectiveness of Nanostructured Products for the Protection of Volterra (Italy) Panchi…
2022
The aims of the research were to evaluate the effectiveness of the application of nanostructured products on Volterra calcarenite stone and to define the experimental conditions and procedures of accelerated aging tests, able to simulate different degradation on the studied lithotype. The work focused on methods of performing accelerated aging tests in order to simulate different effects of environmental decay involving stone used on a historical site. The rock samples were examined before and after three treatment types: cyclic salt spray chamber, cycles of freezing–thawing and cycles of thermal shock. After each artificial aging cycle, changes in appearance were noted and chemical and phy…
La pierre et les hommes en Bourgogne. Archéologie et histoire d'une ressource en œuvre du Moyen Âge à l'Époque Moderne
2014
In order to go further limits inherent to subject disjunction, or those imposed by sources, periods or sites, this thesis emphasises a multidisciplinary and diachronic approach of stone supply on medieval and modern building sites. Thanks to the confrontation of buildings with different origins and functions, this work tries to dissect process of choices and stone supply network. It finally considers connection between people and a natural ressource.
Le Clos de Vougeot (Côte-d’Or) : nouvelles observations sur les matériaux de construction et la chronologie du bâti médiéval
2009
Mithilfe sehr unterschiedlicherMethoden hat es sich diese Arbeit vor allem zur Aufgabe gemacht, bestimmte Phasen der Baugeschichte des Clos de Vougeot zu verstehen, um die Organisation und die Entwicklungen eines Zisterzienserhofsin Hinsicht auf diesozialen und historischen Wandlungen besser zu verstehen. Diese Studie bot ebenfalls Gelegenheit, die geologischen Eigenschaften der im Clos de Vougeot eingebrachten Baumaterialien genauestens zu untersuchen und neue Erkenntnisse zum Bau dieser Gebäude zu gewinnen und zu präzisieren.
Il diportismo nautico e le attività economiche in Sardegna
2013
Operating in a complex globalized world, tourism destinations are continuously challenged to improve their performance in order to stay competitive in a dynamic environment they have to identify new potential markets, to develop networks, clusters and new products. Today the current forms of tourims that are emerging request to spend leisure time as actively as possible and the development of niche tourism with these characteristics can represent a sustainable development strategy for destinations ...
The redesign of an Italian building to reach net zero energy performances: A case study of the SHC Task 40 - ECBCS Annex 52
2011
In the framework of international actions to reduce the energy requirements and greenhouse gases emissions due to buildings, a new International Energy Agency task has been recently established in order to study Net Zero Energy Buildings (NZEBs). The commonly shared concept of NZEB, is a building whose annual balance of energy consumptions tends to zero. This concept is still too imprecise and the authors of this paper participate to the activities of SubTask B of IEA Task40 with the aim of establishing an internationally agreed understanding on NZEBs. The task is based on a common methodology for identifying and refining design approaches and tools to support industry adoption of innovativ…
Non-linear analysis of plane steel prestressed truss in fire
2002
The concept of analysis of 2-D static loaded prestressed steel trusses till failure during fire using a modified method of forces is presented. Failure of steel trusses in fire is based on the criterion of stresses. Behaviour of steel is described by non-linear constitutive model (based on hypo-elastic Ramberg-Osgood formula and Dorn creep theory) and Plem proposition (for string). Both models are approximated in calculations by hyperbolic Norton-Bailey rule. Fire simulates thermal force as an action of high temperature that increases linearly up to some level. The complete formulation of this method is illustrated by the algorithm of model parameters identification. Analysis of results for…
Fighting the Consequences of the COVID-19 Pandemic: Mindfulness, Exercise, and Nutrition Practices to Reduce Eating Disorders and Promote Sustainabil…
2023
Over the past two years, the world’s population has been tested by the COVID-19 health emergency. This has changed population habits worldwide by encouraging a sedentary lifestyle and overnutrition. Isolation and reduction of social life, for most of the population, was mandatory but it quickly became a new lifestyle. Nowadays, we are encountering the consequences with an increase in nutritional associated disorders and conditions that cause illnesses in the general population. These disorders include diet excesses that lead to obesity and diet deficiencies and malnutrition which could rapidly lead to death. These eating disorders are very complex to manage because they become mental disord…
Organisational climate and employee health outcomes: a systematic review
2019
Organisational climate, particularly safety climate, has been documented as a crucial element in promoting occupational health and safety. However, most previous studies have focused more on safety issues (e.g., injuries and accidents) rather than health outcomes (e.g., illnesses, stress, etc). A comprehensive review is also lacking in relation to understanding the organisational climate–health relationship between different levels of analysis, different data sources and different analytical procedures. We conducted a systematic review to investigate previous scholarly contributions to organisational climate and health. The reviewed articles were obtained from three databases: ISI Web of Kn…
#How Can We Help You?: An Instagram-Based Online Self-Help for Eating Disorders
2023
In recent years, there has been a noticeable increase in online self-help treatments and peer-support programs for eating disorders. The possibility of easily accessing them anytime makes these programs an important support tool and an influencing source for increasing motivation to change. The aim of this work is to describe the #How can we help you? project, its initial feedback received from users, and its future directions. Researchers and clinicians developed an Instagram profile (Dicci Come Aiutarti) based on psychoeducation, aimed at orienting those suffering from a self-reported eating disorder towards clinical care, providing information about eating concerns and related constructs…
Assessing the Open Trenches in Screening Railway Ground-Borne Vibrations by Means of Artificial Neural Network
2009
Reducing ground borne vibrations in urban areas is a very challenging task in railway transportation. Many mitigation measures can be considered and applied; among these open trenches are very effective. This paper deals with the study of the effect, in terms of reduction of vertical and horizontal displacements and velocities, of the open trenches. 2D FEM simulations have been performed and several open trench configurations have been analysed varying the main geometric features such as width and depth, distance from the rail, thickness of the soil layer over the rigid bedrock, type of the ground, ratio between the depth of the trench, and the thickness of the soil layer. For quantifying t…
