Atraso da poda hibernal em "Chardonnay" e "Pinot Noir" (Vitis vinifera L.) na Serra Gaúcha-RS.

Nos últimos anos tem sido observado no Sul do Brasil alterações climáticas que culminam com picos de calor no inverno e frio estendido na primavera. Os picos de calor podem fazer com que as videiras precoces brotem antecipadamente e sejam danificadas posteriormente por frentes frias na primavera

How a Diverse Research Ecosystem Has Generated New Rehabilitation Technologies: Review of NIDILRR’s Rehabilitation Engineering Research Centers

Over 50 million United States citizens (1 in 6 people in the US) have a developmental, acquired, or degenerative disability. The average US citizen can expect to live 20% of his or her life with a disability. Rehabilitation technologies play a major role in improving the quality of life for people with a disability, yet widespread and highly challenging needs remain. Within the US, a major effort aimed at the creation and evaluation of rehabilitation technology has been the Rehabilitation Engineering Research Centers (RERCs) sponsored by the National Institute on Disability, Independent Living, and Rehabilitation Research. As envisioned at their conception by a panel of the National Academy of Science in 1970, these centers were intended to take a “total approach to rehabilitation”, combining medicine, engineering, and related science, to improve the quality of life of individuals with a disability. Here, we review the scope, achievements, and ongoing projects of an unbiased sample of 19 currently active or recently terminated RERCs. Specifically, for each center, we briefly explain the needs it targets, summarize key historical advances, identify emerging innovations, and consider future directions. Our assessment from this review is that the RERC program indeed involves a multidisciplinary approach, with 36 professional fields involved, although 70% of research and development staff are in engineering fields, 23% in clinical fields, and only 7% in basic science fields; significantly, 11% of the professional staff have a disability related to their research. We observe that the RERC program has substantially diversified the scope of its work since the 1970’s, addressing more types of disabilities using more technologies, and, in particular, often now focusing on information technologies. RERC work also now often views users as integrated into an interdependent society through technologies that both people with and without disabilities co-use (such as the internet, wireless communication, and architecture). In addition, RERC research has evolved to view users as able at improving outcomes through learning, exercise, and plasticity (rather than being static), which can be optimally timed. We provide examples of rehabilitation technology innovation produced by the RERCs that illustrate this increasingly diversifying scope and evolving perspective. We conclude by discussing growth opportunities and possible future directions of the RERC program

The co-operative university: Labour, property and pedagogy

I begin this article by discussing the recent work of academics and activists to identify the advantages and issues relating to co-operative forms of higher education, and then focus on the ‘worker co-operative’ organisational form and its applicability and suitability to the governance of and practices within higher educational institutions. Finally, I align the values and principles of worker co-ops with the critical pedagogic framework of ‘Student as Producer’. Throughout I employ the work of Karl Marx to theorise the role of labour and property in a ‘co-operative university’, drawing particularly on later Marxist writers who argue that Marx’s labour theory of value should be understood as a critique of labour under capitalism, rather than one developed from the standpoint of labour

Formação de profissionais para a participação na gestão de desastres e emergências em saúde

An investigation had the objective of developing and testing a model for health professionals’ education in disaster management. The methodology developed by the Association for Prevention Teaching and Research, adapted for use in the Brazilian context was used. The research was developed in three phases: (1) selection of competences and search of referential in the databases: MEDLINE via PubMed, Google Scholar, Lilacs and Scielo; (2) development of educational modules; (3) application to a group of students at a University of Southern Brazil. In the 27 references identified, 71 competences were selected and organized according to the National Curriculum Guidelines. The model was available at the Moodle Platform, as a self-directed course to undergraduate students. In comparing the results of pre and post-test a significant difference in all modules was found. The method proved to be effective and the model can be applied to undergraduate students, and its content assimilated in their Curriculum at Universities in Brazil.A investigação teve o objetivo de desenvolver e testar um modelo para a formação de profissionais de saúde em gestão de desastres. A metodologia desenvolvida pela Association for Prevention Teaching and Research, adaptada para uso no contexto brasileiro foi utilizada. A pesquisa foi desenvolvida em três fases: (1) busca de referenciais e seleção de competências em bibliografia nas bases de dados MEDLINE via PubMed, Google Scholar, Lilacs e Scielo em Português, Espanhol e Inglês; (2) desenvolvimento de módulos de educação a partir de objetivos educacionais que nortearam a escolha dos conteúdos; (3) aplicação a um grupo de estudantes da área da saúde de uma Universidade do Sul do Brasil e avaliação da aprendizagem por meio de pré e pós-teste. Nos 27 referenciais identificados foram selecionadas 71 competências. Estes foram organizados segundo as habilidades das Diretrizes Curriculares Nacionais. O modelo foi disponibilizado em Ambiente Virtual de Aprendizagem na Plataforma Moodle, sob forma de curso auto instrutivo para estudantes de graduação da área de saúde de julho a setembro de 2020. Na comparação dos resultados do pré e pós-teste houve diferença significativa em todos os módulos. Os estudantes consideraram que o curso atendeu as expectativas, que os conteúdos foram suficientes e que a organização foi adequada para ser assimilada nos currículos. Os resultados obtidos evidenciam que o método adotado se mostrou eficaz, podendo ser aplicado aos estudantes da área da saúde e assimilado nos currículos de Instituições de Ensino Superior em todo o Brasil e em países cujo idioma seja o português

From Cleanroom to Desktop: Emerging Micro-Nanofabrication Technology for Biomedical Applications

This review is motivated by the growing demand for low-cost, easy-to-use, compact-size yet powerful micro-nanofabrication technology to address emerging challenges of fundamental biology and translational medicine in regular laboratory settings. Recent advancements in the field benefit considerably from rapidly expanding material selections, ranging from inorganics to organics and from nanoparticles to self-assembled molecules. Meanwhile a great number of novel methodologies, employing off-the-shelf consumer electronics, intriguing interfacial phenomena, bottom-up self-assembly principles, etc., have been implemented to transit micro-nanofabrication from a cleanroom environment to a desktop setup. Furthermore, the latest application of micro-nanofabrication to emerging biomedical research will be presented in detail, which includes point-of-care diagnostics, on-chip cell culture as well as bio-manipulation. While significant progresses have been made in the rapidly growing field, both apparent and unrevealed roadblocks will need to be addressed in the future. We conclude this review by offering our perspectives on the current technical challenges and future research opportunities

Complex Calculations during Cardiopulmonary Bypass—1987 Technology

(J. Extra-Corpor. Technol. 19[4]: p. 408-411 Winter 1987). Programmable calculators have become increasingly valuable to the conduct of cardiopulmonary bypass (CPB). We report the upgrading of our previous system with current technology. A Sharp PC-2500 portable microcomputer was chosen because of its low cost, easy programmability, rechargeable battery, and built-in printer. This system has allowed perfusionists to perform an increasing number of complex calculations with more accuracy and efficiency. In addition, it offers expanded memory and a permanent record of its calculations. We have used the new system in over 250 cases of CPB without problem. Although the flexibility of such a system allows customization to fit individual needs, we advise that any program be carefully tested and debugged to prevent serious mishap
