The ring compression test: Analysis of dimensions and canonical geometry

The compression ring test is universally accepted as a perfectly valid method by which determine simply and reliably the adhesion friction factor in a plastic deformation process. Its methodology is based on the application of geometric changes as both the reduction in thickness as the decrease in bore inner diameter in the strained ring itself. In this paper the performance of that test is the basis for establishing the coefficient of friction on a forging process so that, given this, its application to Upper Bound Theorem (UBT) by model Triangular Rigid Zones (TRZ), enable the establishment an intercomparison with empirical force, reaching a cuasivalidation of this Theorem in a certain range.Universidad de Málaga.

Disc volume properties from MRI in adolescent idiopathic scoliosis: correlation to surgical outcome

In young scoliotic patients, the post-operative consequence of spine fusion upon the free lower lumbar spine is one of the major concerns of the surgical treatment. The remodeling of free-motion segment and the role of discs below thoraco-lumbar fusions remains unknown. However, disc hydration and mass exchange flow between disc and vertebral body should play a significant role in the mechano-biology of the vertebral segment. Magnetic resonance imaging is relevant to study intervertebral discs in young scoliotic patients since related to hydration and non-radiant

Mulheres que tecem memórias e narram histórias

Estudar o processo de construção social das contadoras de história da região do Cariri do Estado do Ceará, Nordeste do Brasil sob a perspectiva da dimensão cultural, requer da pesquisa que evidencie os modos como essas mulheres percebem e narram a história social e suas próprias vidas. Contar história é uma forma de trazer as experiências das mulheres e as singularidades da arte de fazer e dizer o passado e o presente. Trabalhar com a dimensão da memória é chegar ao passado através da narrativa do presente. Por ser uma pesquisa qualitativa, privilegia-se o trabalho de campo utilizando técnicas que possibilitam a escuta, a experiência das mulheres. Apoia-se na proposta da pesquisa qualitativa de caráter etnográfico com abordagens metodológicas da história oral. Tecendo memórias, as mulheres dessa pesquisa contam a história da sua cidade, da sua família, dos personagens religiosos que habitam a fé e os oratórios das suas casas e comunidade. Utilizam canetas, computadores e rimas quando constroem as histórias narradas em cordéis, e lápis, agulhas, linhas e retalhos quando bordam os personagens das suas histórias nos panôs.A study about the social construction process of Cariri's Region storytellers in the Ceara State, Northeast of Brazil under the cultural dimension's perspective requires a research methodology which is able to demonstrate the ways these women perceive and narrate the social story and their own lives. Storytelling is a way to bring women's experiences and the art's singularities of reconstructing and telling the past and the present. The exploration of the memory's dimension means to achieve the past through the narrative of the present. Since this is a qualitative research, it focuses on field work that utilizes techniques which enable the listening of the women's experience. It may be characterized as a qualitative research with an ethnographic character based on an oral story methodological approach. By reconstructing their memories, the women of this research narrate the history of his city, his family, religious characters related to their faith and the oratories of their homes and community. They use pens, computers and rhymes while they reconstruct the histories which are narrated in "cordel"3. They also use needles, threads when they embroil their characters in ornamental panels

Digital inclusion of the elderly : multiple intelligen- ces and ergonomic approach for teaching material development

Este artigo apresenta um estudo da participação direta de usuários idosos no processo de elabo¬ração de material didático, utilizando o design centrado no usuário com o intuito de deixá-lo mais atrativo, acessível e didático. Procurou-se alicerçar todas as atividades desse material com as inteligências múltiplas defendidas por Howard Gardner. Para o processo de validação desse material didático, utilizou-se a técnica empírica de oficinas de interação, que exige a participação direta dos envolvidos. Assim, foi realizada uma avaliação qualitativa desses materiais pelos usuários, cujos resultados são aqui apresentados. Participaram deste estudo 31 idosos, com média de idade de 65 anos e com grau de escolaridade heterogênea, frequen¬tadores do projeto de extensão “Oficinas de Informática para a Terceira Idade”, da Universidade Federal de Santa Catarina. _________________________________________________________________________________ ABSTRACTThis paper presents the study of elderly users direct participation in the preparation of teaching material using user-centered design in order to make it more attractive, accessible and educational.

The sources of authority for shamanic speech : Examples from the Kham-Magar of Nepal

Among the Kham-Magar, an indigenous population of West Nepal, shamans end their long ritual chants with the promise to keep to the terms of the contract that bind human beings to the supernatural entities. In this paper I identify the sources of authority that allow the ritual specialists of this community to act as its spokespersons toward invisible partners. Taking up the debate initiated in the introduction to this special issue, I begin by confronting the notion of "social magic" that Bourdieu (1982:97-161) sees as the source of all authority, with the "discourse of magic" proposed by the linguist Tzvetan Todorov (1978:246-82), showing that the two approaches are less inconsistent than might first appear to be the case: both suggest that the efficacy of ritual speech rests on deception. The second part of the paper turns to Kham-Magar ethnography; it examines the staging of the sources of shamanic authority in the ceremony of consecration of a new shaman. I partly challenge Bourdieu's (1982:20) vision that ritual techniques are mainly techniques of domination, ensuring that the dominant power is reproduced, rather than being a source of authority for ritual specialists: "Rituals represent the limit of all situations of imposition1 where, through the application of a technical competence, however imperfect, a primarily social competence is exercised: the competence of the speaker who is authorized by his or her group to speak with authority." The third part looks precisely into the "competence of the speaker," shamanic speech itself, for possible sources of his or her ritual authority. I explore the pragmatic effects of the ritual use of language, including a reflexive definition of the performer. I argue that these techniques set up the conditions for the emergence of a transcendent authority.Issue title: Authoritative Speech in the Himalayas. Anne de Sales is an anthropologist, who holds the position of Senior Researcher in the French National Centre for Scientific Research (CNRS). Her publications on Nepal include a monograph on an ethnic minority, the Kham-Magar, and numerous articles on shamanic practices and oral literature.

Application of the Upper Bound Theorem to indentation processes with tilted punch by means of Modular Model

Nowadays, the indentation processes are resuming it importance due to the new deformation processes that are being developed, as the Incremental Forming Process (IFP) or the Localized-Incremental Forming Process (LIFP) [1]. In this paper, a tilt punch is considered in order to cover the largest possible number of cases in the study of the indentation,. Thus, using combinations of flat and tilt punches, it will be possible to analyze complex geometries in future studies. Present study shows the analysis of the indentation process by the Upper Bound Theorem (UBT), when it is performed with a tilt punch. A modular model is developed, compound by two modules of Triangular Rigid Zones (TRZ) each [2], which adapts to the configuration of the punch.Universidad de Málaga.
