Letter from Karl I. Zimmerman and T.R. Martinez to Toshiko Chuman
No full textA letter to Toshiko Chuman (nee Nakamura) from Karl I. Zimmerman, District Director of Immigration and Naturalization Service (INS) in Philadelphia, and T.R. Martinez, Acting Chief, Detention, Deportation and Parole Section. The letter regards his release from INS into the custody of her attorney, Wayne M. Collins.The Chuman (Hayao "Sam" and Toshiko) Papers documents the World War II experiences of Hayao "Sam" and Toshiko Chuman, who were Kibei Nisei born in the United States but grew up and completed school in Japan, and then returned to the U.S. prior to the war. It chronicles the Chuman's incarceration from the Santa Anita Assembly Center, through Jerome, Rohwer, Tule Lake camps, and the Santa Fe and Crystal City internment camps as well as their struggle for restoring their U.S. citizenships in the 1960s. The digital collection consists of mostly textual material, including correspondence, affidavits, incarceration camp records, lease agreements, financial documents, receipts, pamphlets, and booklets

Season 10 Episode 11: Healthcare Around the World
No full textFans of U.S. health care reform point out that many other countries provide coverage for all their citizens, and no one files for bankruptcy due to medical bills. But how exactly do these countries do it? January Series guest & journalist T.R. Reid, author of The Healing of America: A Global Quest for Better, Cheaper, and Fairer Health Care, tells of his travels comparing systems around the world. Shirley Hoogstra hosts. Episode #1011

Gender dynamics in data collection on reproductive health: field experiences in Kerala, India
No full textReproductive health researchers tend to choose interviewers of the same sex as those interviewed. In many societies, it is considered unacceptable for men to interview women on topics of an intensely personal nature like sexuality or contraceptive use. In this paper, the author analyzes 21 interviews and 16 focus group discussions (FGDs) undertaken during a field study on the Quality of Services in the Indian Family Welfare Programs conducted in Kerala. The analysis was based on the model which identifies the principal participants in the interview as the respondent and the interviewer. In all these cases the contradiction between the gendered roles of the interviewer and interviewee are visible. However, if viewed in the context of the model provided by Briggs, it is clear that these contradictions are due to the differences in the social roles that the interviewers assumed and that the respondents ascribed to them and in the interactional goals of the interviewers and the respondents. Contradictions were also experienced during the FGDs. Educational sessions on contraception are a good tool for gathering sensitive information instead of the conventional interview, where the gendered roles are so crucial to the information gathering exercise itself
Projeto de elementos magnéticos planares utilizados em fontes de alimentação chaveadas visando a redução das perdas de energia
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro Tecnológico. Programa de Pós-graduação em Engenharia ElétricaEste trabalho aborda o estudo de transformadores e indutores planares bem como apresenta o desenvolvimento de uma metodologia para projeto destes elementos magnéticos, os quais são utilizados em fontes de alimentação que operam em comutação sob freqüência elevada (de 50 kHz a 100 kHz). O estudo engloba desde os materiais utilizados na confecção de um elemento magnético até seu projeto e otimização. É realizada uma análise dos efeitos devidos à operação em alta freqüência. Entre estes efeitos, destacam-se as perdas no núcleo e nos enrolamentos, as indutâncias de dispersão e a capacitância entre enrolamentos. Para análise das perdas no núcleo e nos enrolamentos, foi desenvolvida uma bancada experimental, composta por um circuito inversor em ponte completa e um instrumento virtual, que permite fazer uma série de medidas e traçar gráficos do comportamento das perdas com variação de diversos parâmetros. A partir dos valores adquiridos, foi possível obter modelos para as perdas magnéticas, incluindo o valor dos seus parâmetros. Com estes modelos e com a utilização de ferramentas de otimização, foi estabelecida uma relação entre a indução magnética e a densidade de corrente que possibilita o funcionamento do transformador ou do indutor com perdas magnéticas mínimas. Para auxiliar no desenvolvimento dos projetos, foi desenvolvido um programa computacional, no qual foram inseridos os modelos analíticos e os valores dos parâmetros correspondentes, obtidos no decorrer do trabalho. Vários indutores e transformadores foram projetados, montados e avaliados, mostrando através dos resultados o bom funcionamento da metodologia proposta. This work concerns the study of planar transformers and inductors as well as presents the development of a methodology for designing these magnetic elements, which are used in power supplies operating at high frequencies (from 50 kHz to 100 kHz). The study includes the materials used in the manufacture of a magnetic element, the design and its optimization. It was made an analysis of the effects due to operation at high frequencies. Among these effects, there are the core and winding losses, the leakage inductance and inter-winding capacitance. For the analysis of core and winding losses, it has been developed a workbench consisting of a full bridge inverter and a virtual instrument, which allows making a series of measures and drawing graphs of the behavior of losses with different parameters. From the obtained values, it was possible to construct models for the magnetic losses, including their parameter values. With these models and the use of optimization tools, it was established a relationship between the magnetic induction and current density that allows operation with minimum losses. In order to assist in the development of projects, a computer program has been developed, which includes the analytical models and the corresponding parameter values, obtained in the course of this work. Several inductors and transformers were designed, assembled and evaluated, and the obtained results show the validity of the proposed methodology

Optimalisatie staalconstructies met beperkt aantal verschillende profielen
No full textHet is mogelijk om lichte en goedkope staalconstructies te ontwerpen terwijl de rekenkracht ten opzichte van bestaande methodes beperkt is. Dit volgde, na parametrisch onderzoek, uit een afstudeeronderzoek vorig jaar aan de TU Delft, bij de faculteit Civiele Techniek. Deze methode is tevens toegepast op het constructief ontwerp van een ligger zoals ontworpen door Royal HaskoningDHV. Op verzoek licht de auteur toe hoe een optimaal ontwerp, volgens een nieuwe groeperingsmethode, met een beperkt aantal verschillende profielen goed toepasbaar is.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Applied Mechanic
