Crack detection using electrostatic measurements
2001
In this paper we extend recent work on the detection of inclusions using electrostatic measurements to the problem of crack detection in a two-dimensional object. As in the inclusion case our method is based on a factorization of the difference between two Neumann-Dirichlet operators. The factorization possible in the case of cracks is much simpler than that for inclusions and the analysis is greatly simplified. However, the directional information carried by the crack makes the practical implementation of our algorithm more computationally demanding.
Numerical modelling of out-of-plane response of infilled frames: State of the art and future challenges for the equivalent strut macromodels
2017
Abstract Infill-frame interaction constitutes a still open question both in research and in practicing engineering. Computational models used to predict this interaction are, in most cases, addressing the estimation of the response of the infilled frames when subjected to actions parallel to their plane. However, the observation of the post-earthquake damage has demonstrated that infills, weakened by the in-plane actions, may fail out-of-plane increasing the risks associated to the earthquake scenarios. In spite of this, different studies have shown that infills, if properly designed and supported by the frame, exhibit a significant strength and displacement capacity when called to resist t…
The Assessment of Professionalism for Ambulance Personnel – Problems and Challenges
2015
The purpose of this paper is to clarify whether annual knowledge testing at a work place promotes Ambulance professionals for personnel development, and if it providesthe possibility to assess personnel’s competence and professionalism. The results of 1693 ambulance personnel’s annual knowledge testing in years 2011, 2012,2013 are analysed in the research. The results obtainedreflect that in all stages knowledge improves, but there are not possibility to assess personnel’s competence and professionalism for building personnel development programs in the future.
Investigating consumers' representations of beers through a free association task: A comparison between packaging and blind conditions
2013
International audience; Food behavior has been shown to be influenced by top-down processes such as expectations generated from the mental representations of product. Investigating how a product is represented in consumers' mind is therefore essential to a better understanding of food behavior. As traditional and typical products are particularly prone to expectation effects, these products are well suited to explore consumer's mental representations. Among traditional products, beers are certainly of interest for both product development and marketing. A free association task was conducted in two evaluation conditions. Participants were asked to state what came to their mind while evaluati…
S3 guidelines: Epicutaneous patch testing with contact allergens and drugs – Short version, Part 1
2019
Epicutaneous patch testing is the diagnostic standard for the detection of allergic contact dermatitis. The present guidelines are aimed at residents and board-certified physicians in the fields of dermatology and allergology as well as other medical specialties involved in establishing the indication for patch testing and its execution in patients with contact dermatitis and other forms of delayed-type hypersensitivity. The target audience also includes other health care providers and insurance funds. Based on a systematic literature search and a formal consensus process (S3), the guidelines were developed by dermatologists in collaboration with pediatricians, occupational medicine physici…
Characterization of chronic obstructive pulmonary disease in dairy farmers
2020
International audience; Background - Although farming is often considered a risk factor for COPD, data regarding the burden and characteristics of COPD in dairy farmers are sparse and conflicting. Objectives - To characterize COPD in dairy farmers. Methods - 4788 subjects entered two parallel COPD screening programs, one in agricultural workers and one in general practice from 2011 to 2015. Subjects with COPD were invited to participate in the characterization phase of the study. Those who accepted were included in two subgroups: dairy farmers with COPD (DF-COPD) (n = 101) and non-farmers with COPD (NF-COPD) (n = 85). Patients with COPD were frequency-matched with subjects with normal spiro…
Influence of roasting and different brewing processes on ochratoxin A content in coffee determined by high-performance liquid chromatography-fluoresc…
2008
A rapid and reliable procedure has been developed for the determination of ochratoxin A (OTA) in green and roasted coffee. The method consists of extraction of the sample with methanol-5% aqueous sodium hydrogen carbonate/1% PEG8000 (20:80), followed by immunoaffinity column (IAC) clean-up and, finally, high-performance liquid chromatography (HPLC) determination with fluorimetric detection. Mean recoveries for green and roasted coffee spiked at different levels ranging from 94 and 105% were obtained. The limit of determination (S/N = 3) was 0.032 ng g(-1) and the precision (within-laboratory relative standard deviation) was 6%. The method described has been used to assess the influence of r…
Growth, Phenology, Production and Oil quality of the Cultivar Arbequina in high-density hedgerow in four different areas of Italy
2012
The success of the traditional olive-growing sector in EU countries – characterised by high production costs and a low selling price for the oil – was mainly determined by EU subsidies available for the sector. With the opening of the "free trade" area and a cut in subsidies in 2014, crucial changes in the sector are now needed. In order to increase the competitiveness of EU olive production, attention should be given to new high-yielding, mechanized cultivation systems. In the 90s, Spain introduced new high-density planting systems (1,200-2,000 plants/ha) using three low-vigour and early-fruiting cultivars (‘Arbequina’, ‘Arbosana’ and ‘Koroneiki’). Italian olive production lies in a geogra…
Evaluation of hand-arm vibrations during the use of portable olives harvesters
2013
The use of portable shakers in olives harvesting is becoming increasingly, especially in Sicily, both to reduce the costs of production and to assure the oil quality. Nevertheless, it’s well known that the use of such tools may involve risk of exposure to hand-transmitted vibration. Such exposure to vibrations is a potential cause of muscular/skeletal pains in hand–arm system, and specific pathologies such as Vibration-Induced White Finger (VWF) and Carpal Tunnel Syndrome (CTS), Hand–Arm Vibration Syndrome (HAVS). The aim of this study was to assess the level of exposure to hand-arm vibration of the operators during the use of portable shakers for olives harvesting. Two different commonly u…
Cultural institutions as agents of urban and community regeneration in the (post-)pandemic city. The case of the «Laboratorio Zen Insieme» in Palermo
2022
Although all cities in the world have been affected by the COVID-19 pandemic, its impacts on the territories, yet to be understood, are unevenly distributed, revealing extremely varied imbalances depending on the places. However, it is clear that the virus and its variants have aggravated pre-existing socio-spatial inequalities, creating new ones and bringing attention back to those implications between space, planning, public health and citizenship that are at the origins of contemporary urbanism. In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and g…
