Mathematical modeling of a vehicle crash test based on elasto-plastic unloading scenarios of spring-mass models
2011
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher on SpringerLink: htp://dx.doi.org/10.1007/s00170-010-3056-x This paper investigates the usability of spring which exhibit nonlinear force-deflection characteristic in the area of mathematical modeling of vehicle crash. We present a method which allows us to obtain parameters of the spring-mass model basing on the full-scale experimental data analysis. Since vehicle collision is a dynamic event, it involves such phenomena as rebound and energy dissipation. Three different spring unloading scenarios (elastic, plastic, and elasto-plastic) are covered…
Investigation of vehicle crash modeling techniques: theory and application
2013
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-013-5320-3 Creating a mathematical model of a vehicle crash is a task which involves considerations and analysis of different areas which need to be addressed because of the mathematical complexity of a crash event representation. Therefore, to simplify the analysis and enhance the modeling process, in this work, a brief overview of different vehicle crash modeling methodologies is proposed. The acceleration of a colliding vehicle is measured in its center of gravity—this crash pulse contains detailed informati…
European energy balance research to prevent excessive weight gain among youth (ENERGY) project: Design and methodology of the ENERGY cross-sectional …
2011
Published version of an article from: Bmc Public Health. Also available from the publisher: http://dx.doi.org/10.1186/1471-2458-11-65. Open Access Background: Obesity treatment is by large ineffective long term, and more emphasis on the prevention of excessive weight gain in childhood and adolescence is warranted. To inform energy balance related behaviour (EBRB) change interventions, insight in the potential personal, family and school environmental correlates of these behaviours is needed. Studies on such multilevel correlates of EBRB among schoolchildren in Europe are lacking. The ENERGY survey aims to (1) provide up-to-date prevalence rates of measured overweight, obesity, self-reported…
Intensity of the phenomenon of refusal to subject children to preventive vaccinations in the years 2002-2016 based on analysis of primary health care…
2018
Background. Vaccinations are the most effective method for preventing infectious diseases. Massive implementation of long-term vaccinations strategies has resulted in elimination or a reduced incidence of many infectious diseases. Aim of the study. To evaluate the intensity of the phenomenon of refusal to subject children to preventive vaccinations by attempting to characterize the parental group who refuse to vaccinate their children, determining the type and number of unrealized vaccinations, and identifying the reasons for being unvaccinated. Material and methods. The research material was medical records from the Non-Public Heath Care Unit in Opole. It concerned implementation of the Pr…
Percezione della importanza della vaccinazione antinfluenzale tra gli specializzandi in Igiene e Medicina Preventiva Italiani. Studio conoscitivo del…
2012
Riassunto Uno studio conoscitivo condotto tra i medici in formazione specialistica in Igiene, Medicina Preventiva e Sanità Pubblica italiani è stato condotto in 25 scuole di specializzazione italiane di tale disciplina (78,1% del totale). Ciascun partecipante è stato intervistato tramite un questionario anonimo ed autosomministrato con domande riguardo attitudini, pratiche e conoscenze sull’influenza e la relativa vaccinazione. La vaccinazione contro l’influenza stagionale 2010-2011 e 2011-2012 è significativamente associata con l’essersi vaccinato almeno 3 volte nelle ultime cinque stagioni influenzali. Gli specializzandi che hanno preso parte durante il loro percorso formativo a campagne …
The Italian Version of the Adult Vaccine Hesitancy Scale (aVHS) for the Working-Age Population: Cross-Cultural Adaptation, Reliability, and Validity
2022
The adult Vaccine Hesitancy Scale (aVHS) is valid and reliable for evaluating attitudes toward vaccine preventable diseases (VPDs). The aim of the present study was to evaluate the cross-cultural adaptation, reliability, and validity of the Italian version of the aVHS. After cross-cultural adaptation of the aVHS, internal consistency (IC), intra-class correlation (ICC), and content validity (S-CVI) were evaluated through a survey on 160 workers. Results of the ICC were analyzed on questionnaires administered twice at a distance of two months and revealed a satisfactory reproducibility (0.87). The IC of the aVHS was assessed by the Cronbach alpha coefficient test, with a result of 0.94, demo…
Neumonía adquirida en la comunidad: tratamiento ambulatorio y prevención
2015
Resumen: La neumonía adquirida en la comunidad (NAC) en la edad pediátrica ha sufrido, en la última década, una serie de cambios epidemiológicos, clínicos, etiológicos y de resistencias a antibióticos, que obligan a replantear su abordaje terapéutico. En este documento, dos de las principales sociedades de especialidades pediátricas involucradas en el diagnóstico y tratamiento de esta entidad, como son la Sociedad Española de Infectología Pediátrica y la Sociedad Española de Neumología Pediátrica, así como el Comité Asesor de Vacunas de la AEP, proponen unas pautas consensuadas de tratamiento y prevención, con el fin de proporcionar a todos los pediatras una guía actualizada. En esta primer…
Starptautisku lielpasākumu ekonomiskās ietekmes novērtēšana.
2016
Starptautisku liepasākumu norise rada dažāda veida ietekmi vietējā, reģionāla un nacionālā līmenī, tostarp ekonomisko ietekmi, kuras novērtēšanas tradīcija pasaulē izveidota jau pagājušajā gadsimtā, bet Latvijā kļuvusi aktuāla vien pēdējos gados. Darba mērķis ir pētīt un apkopot informāciju par starptautiskiem lielpasākumiem, to radīto ietekmi un ekonomiskās ietekmes novērtēšanas metodēm, kā arī izstrādāt priekšlikumus lielpasākumu novērtēšanā un norisē ieinteresētajām pusēm. Bakalaura darba izstrādes rezultātā tika noskaidroti galvenie ieguvumi un ekonomiskā ietekme, ko rada starptautisku lielpasākumu norise Latvijā, kā arī to novērtēšanas iespējas. Bakalaura darbs sastāv no ievada, 3 noda…
Valuation Effects of Listing on a More Prominent Segment of the Stock Market: Evidence from France
2002
We examine the behaviour of stock prices during the period around the transfer to the Marchea Reglement Mensuel. First, we discuss the financial reasons, which can justify abnormal returns around the transfer. Second, an event study based on a sample of 71 firms is set up to test the existence of the exchange listing effect on the French market. Third, we explore three hypotheses in order to explain the impact on stock returns: the informative content of the transfer, the increase in the relative size of the firm’s investor base, and the reduction of trading costs (immediacy and adverse selection). Cross–sectional regressions show that the increase in the relative size of the firm’s investo…
A framework for identifying the legacies of a mega sport event
2015
A mega sport event involves huge investments in city infrastructure. After the event, the structures that remain may be an asset to the stakeholders, or they may be a burden. Faced with high costs, the taxpayer demands that the event-related social, economic and ecological changes will in the end have improved living conditions for the host city. But it is not easy to identify sport event legacies in their entirety, because event-related changes may be confused with non-event-related development, and because a wide variety of areas and stakeholders are affected. This paper looks at how to identify legacies, who is affected by the legacies, how long they last, and how to judge whether a lega…
