Most of the adhesives used in the marine industry are polymers with a mechanical behaviour which is strongly influenced by the strain rate. Therefore, it is important to predict with accuracy their ...viscous behaviour. To describe their mechanical behaviour in a bonded joint, a viscoelastic-viscoplastic constitutive law is proposed here. The viscous effects on the elastic behaviour are described using a spectral distribution, which divides the viscous strain as the sum of the strains of several viscous mechanisms, each of them with a different characteristic time and weight. The viscoplastic component of the model permits a better description of the strong non-linear behaviour of the adhesives. The parameters of the constitutive law are obtained using an inverse identification procedure coupled with a finite element model. Two creep tests, in two loading directions, are needed in order to identify the viscoelastic part. The viscoplastic part is identified using monotonic tests. In order to validate the behaviour law and the identification procedure, the adhesive HuntsmanTMAraldite 420A/B has been investigated and modelled. All the experimental tests have been conducted using the modified Arcan device.

KM3NeT is a deep-sea infrastructure composed of two neutrino telescopes being deployed in the Mediterranean Sea: ARCA, near Sicily in Italy, designed for neutrino astronomy, and ORCA, near Toulon in ...France, designed for neutrino oscillation physics. To achieve the best performance, the exact location of the optical modules, affected by sea current, must be known at any time and the timing resolution between optical modules must reach the nanosecond. Moreover, the properties of the environment in which the telescopes are deployed must be continuously monitored because they affect the timing and positioning calibration. KM3NeT is going to deploy several dedicated Calibration Units to meet these calibration goals. Because of the difference in size between ARCA and ORCA, the design of the Calibration Unit is not the same for the two sites. This proceeding describes all the devices, features and purposes of the Calibration Units with a focus on the ORCA Calibration Unit.
Abstract
The KM3NeT collaboration is currently deploying the first detection units of a neutrino observatory in the Mediterranean Sea, which, once completed, will be equipped with thousands of ...so-called digital optical modules. In addition to the detection units KM3NeT has designed an independent calibration unit, housing a set of calibration instruments, including e.g. an acoustic beacon and a laser beacon. The calibration unit and the embedded software developed to operate it are presented here.

O estudo tem como foco a negociação de identidades em situação de conflito em contexto de consulta médica pediátrica de crianças e adolescentes com diagnóstico de Transtorno de Déficit de Atenção e ...Hiperatividade (TDAH), em atendimento de rotina conduzido pela médica. O objetivo consiste em criar inteligibilidades sobre os conflitos familiares consequentes do transtorno e as identidades projetadas/negociadas por pais, crianças e adolescentes com TDAH, para si e para o outro. A pesquisa está ancorada em linhas teóricas da fala-em-interação em atendimento clínico. Situa-se na Linguística Aplicada das Profissões, em articulação com a Análise da Conversa Etnometodológica, em contexto institucional, com a Sociolinguística Interacional e com os estudos discursivos sobre identidades. A metodologia da pesquisa, de natureza qualitativa e interpretativista, com gravação em vídeo de quatro consultas pediátricas, tem caráter etnográfico, mediante observação participante na antessala de atendimento. Os dados foram transcritos de acordo com convenções da Análise da Conversa Etnometodológica. Os resultados das análises mostram a prática profissional da médica nos enquadres de consulta clínica e de orientação psicoeducativa. A médica realiza tanto atividades relacionadas a tarefas de avaliação física e comportamental das crianças e dos adolescentes, em ações que visam ao tratamento medicamentoso e psicológico do TDAH, quanto atos comunicativos como formuladora, mediadora e conselheira na intermediação de conflitos emergentes da inter-relação TDAH, família e escola, resultantes do comportamento dos filhos nas relações familiares e do baixo rendimento acadêmico destes no contexto escolar. Os pais se alinham junto à médica, no enquadre de transtornos escolares dos filhos, e estabelecem enquadres conflitantes junto aos filhos; projetam para si identidades cujos atributos oscilam entre participativos, compreensivos e responsáveis, e impacientes, frustrados e esgotados. As identidades que projetam para os filhos apresentam-se, por vezes, contraditórias, entre filhos amorosos, perspicazes e irritantes; e alunos inteligentes, ineptos e displicentes. As crianças e os adolescentes, embora se alinhem com a médica, nos enquadres de consulta e orientação, rejeitam o estigma de TDAH e projetam para si identidades de alunos e filhos respeitosos e intelectualmente capazes; e para seus pais, na maioria das vezes, de pais impacientes e exigentes em sua educação. O estudo proporciona maior entendimento da complexidade e das múltiplas atividades da atuação profissional da médica na consulta pediátrica, e contribui para uma melhor compreensão das experiências cotidianas de pais, crianças e adolescentes com TDAH, marcadas por conflitos desestruturantes da harmonia entre esses atores sociais nos contextos da escola e da família.
The study focuses on the negotiation of identities during conflict situations in the context of pediatric appointments for children and teenagers diagnosed with Attention Deficit Hyperactivity Disorder (ADHD), in routine care conducted by the doctor. The main purpose consists on creating intelligibilities about the family conflicts resultant from the disorder and the identities projected/negotiated by the parents, children and teenagers with ADHA, for themselves and others. The research is based on theoretical lines of speech-in-interaction regarding clinical care. It is situated on Professions Applied Linguistics, in articulation with the Ethnomethodological Conversation Analysis, in an institutional context, in Interational Sociolinguistics and on discursive studies about identities. The research methodology, of a qualitative and interpretive nature, with video recording of four pediatric appointments, has an ethnographic character, by a participant observation in the Doctor’s office waiting room. Data were transcribed in accordance with conventions of the Ethnomethodological Conversation Analysis. The analyzes results indicate the professional practice of the Doctor concerning clinical care and the psycho-educative orientation. The Doctor carries out activities related to physical evaluation and behavior tasks of children and teenagers, in actions that aim at the ADHA medicated and psychological treatment, and also the communicative acts as a formulator, mediator and advisor when intermediating conflicts emerging from the ADHA, family and school inter-relation, resultant from the behavior of the children in family relation and the their low academic performance in the school context. The parents align with the Doctor, in the framings of their children school disorders, and stablish conflicting framings together with their children; they project to themselves the identities whose attributes oscillate between participative, comprehensive and responsible, and impatient, frustrated and exhausted. The identities that project toward children are occasionally presented as contradictory, among the children considered lovely, insightful and annoying; and intelligent, inept and ungracious students. Children and teenagers, although being aligned with the Doctor, in the framings of appointments and orientation reject the ADHA stigma and project to themselves the identities of students and children considered to be respectful and intellectually capable; and for their parents, most of the time, identities of impatient and demanding parents regarding education. The study provides a greater understanding of the complexity and the multiple activities of the professional performance of the Doctor during the pediatric care, and contributes for a better understanding of the daily experiences of parents, children and teenagers with ADHA, marked by destabilizing conflicts of harmony between these social authors in the school and family contexts.

Occupational safety and health is increasingly considered to be a distinct scientific discipline, with a well-defined place in the labor sciences system. The evolution of research in recent years at ...European and international level has highlighted an increasing interpenetration of occupational safety and health with other scientific disciplines circumscribed or related to the field of industrial engineering, such as medicine and occupational hygiene, ergonomics, sociology, mathematics, computer science etc. In national legislation, the intervention and rescue activity in toxic / explosive / flammable environments has so far proved to be generally appropriate both in terms of prevention and in terms of limiting the effects of technological damage of lesser or greater magnitude. The theoretical and instrumental aspects presented in the paper have a wide applicability, being intended for all rescue stations, regardless of the branch of activity, as well as for specialists in the field of occupational safety and health. Understanding the relationship between the environment, equipment and rescue station personnel and ho-w these three components interact is fundamental to achieving increased efficiency in rescue work.
In the first part of the research, the five concepts used in industrial practice, quality, reliability, maintainability, maintenance and availability are defined, the definitions of which result in ...the structural links between them, all of which equate to the characterization of the functionality of a product. For defining the concept of quality, it is absolutely necessary to detail the four elements that have been defined. The complexity of the concept of reliability is highlighted, which, in a complete presentation, should include technical, operational, commercial and management approaches. The factors that contribute to defining the quality of a mining equipment or equipment are highlighted, given the particular circumstances in which they are exploited. The cause-effect diagram, or the Ishikawa diagram, is a complex way of analyzing a product's quality. The method is based on the detailed determination of the causes that may lead to the appearance of a defect, so that the best possible measures can be taken to remedy it or even prevent it from occurring.
In order to obtain success both in sport, but also in the management, a football organisation must know the marketing environment in which it is operating. The analysis of the environment and the ...planning of the actions corresponding to it are factors that the football club managers have to take into consideration when making administrative and economic decisions with the aim of development. The paper presents a marketing analysis of the LaLiga, the most valuable football league in Spain. As other football leagues, LaLiga can be analyzed as a market, with its characteristics known in economics. Football clubs are active on this market and are influenced by it.

Like any new field in our country, sports marketing needs to be defined in order to perceive, at its true value, the importance it has in economic development (through the income it generates) and ...social (by involving the population in sports activities). The conceptualization of this field must start from the general framework in which sports marketing appeared and developed. With this in mind, this paper aims to discuss the different points of view encountered in theory regarding the definition and classification of sports marketing.
