Transferência de Conhecimento para o Setor Produtivo em Escala Regional: o Caso da FURB
Get PDFDesde que, no século XII, surgiram as primeiras Universidades , estas assumiram e refletiram peculiaridades do contexto social, econômico e político no qual estavam inseridas. No presente, a Universidade está desafiada a contribuir com a constituição de uma sociedade mais justa. É fato que ela vem buscando estreitar suas relações com a sociedade, inclusive com o Setor Produtivo [SP]. Um dos meios para concretizar o estreitamento de laços com o SP é pela via de Parques Tecnológicos e também de Incubadoras de Empresas. Aqui se parte da hipótese de que a FURB vem ampliando sua interação com a sociedade, inclusive com o SP da região em que ela se insere, assim contribuindo para o desenvolvimento socioeconômico do Médio Vale do Itajaí. A pesquisa de que resulta o presente artigo mostrou que, embora ainda de forma incipiente, a FURB tem produzido e transferido conhecimento a partir de demandas que lhe são encaminhadas pela sociedade regional – aí incluído o SP. O propósito central deste artigo é examinar as modalidades de interação entre a FURB e o SP, bem como suas repercussões em termos de desenvolvimento regional a partir de casos selecionados – Instituto Gene, BLUSOFT e Parque Tecnológico Regional

Application and Use of Multivariate Control Charts In a BTA Deep Hole Drilling Process
Get PDFDeep hole drilling methods are used for producing holes with a high length-to-diameter ratio, good surface finish and straightness. The process is subject to dynamic disturbances usually classified as either chatter vibration or spiralling. In this paper, we will focus on the application and use of multivariate control charts to monitor the process in order to detect chatter vibrations. The results showed that chatter is detected and some alarm signals occurs at time points which can be connected to physical changes of the process. --
Chain length dependent termination in butyl acrylate free-radical polymerization studied via stationary and pulsed laser initiated RAFT polymerization
No full textThe chain-length dependence of the termination rate coefficient, k t, in butyl acrylate free-radical polymerization has been determined by two independent methods, RAFT-SP-PLP and RAFT-CLD-T, both employing control of radical chain length by reversible addition fragmentation chain transfer (RAFT) polymerization. Within RAFT-SP-PLP, the polymerization induced by a laser single pulse is monitored via near-IR spectroscopy with a time resolution of microseconds. In RAFT-CLD-T, isothermal reaction rate measurements are carried out via DSC under stationary polymerization conditions. The resulting k t data refer to the situation of living/controlled radical polymerization, where both radical chain length and monomer conversion increase during the course of the reaction. The RAFT-SP-PLP measurements were carried out at 60°C and two pressures, 5 and 1000 bar. The RAFT-CLD-T experiments were run at ambient pressure and at two temperatures, 60 and 80°C, respectively. In absolute value, the termination rate coefficients for identical pressure and temperature deduced from the two methods differ by less than a factor of 2. For the dependence of kt on chain length, i, almost identical information is provided by the two techniques. The chain-length dependence of kt may be described by the power-law expression kt(i) = k t(1,1)i-α with, however, α being different for short-chain and long-chain radicals. RAFT-SP-PLP yields α1 = 1.25 for the short-chain regime from 1 < i < 30, and α2 = 0.22 for chain lengths above i = 50. RAFT-CLD-T results in α1 = 1.04 and α2 = 0.20 in identical chain length regimes. k t(1,1) values are found to be close to 1 × 109 L mol-1 s-1. © 2005 American Chemical Society
[Shock wave treatment for tennis elbow].
No full textRandomized controlled trials were evaluated to assess the effectiveness of extracorporeal shock wave treatment in the management of tennis elbow. Five trials had a mediocre methodology and four trials had a high-quality design. Well-designed randomized control trials have provided evidence of the effectiveness of shock wave intervention for tennis elbow
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Abstract
PURPOSE: To evaluate the role of topical mitomycin C in corneal wound healing (CWH) after photorefractive keratectomy (PRK) in highly myopic eyes.
DESIGN: Prospective, double-masked, randomized clinical trial.
PARTICIPANTS: Seventy-two eyes of 36 patients affected by high (>7 diopters) myopia.
METHODS: In each patient, one eye was randomly assigned to PRK with intraoperative topical 0.02% mitomycin C application, and the fellow eye was treated with a placebo. Postoperatively, mitomycin C-treated eyes received artificial tears (3 times daily, tapered in 3 months), whereas the fellow eye was treated with fluorometholone sodium 2% and artificial tears (3 times daily, tapered in 3 months).
MAIN OUTCOME MEASURES: Uncorrected visual acuity (UCVA) and best-corrected visual acuity (BCVA), contrast sensitivity, manifest refraction, and biomicroscopy. Contrast sensitivity was determined using the Pelli-Robson chart. Corneal confocal microscopy documented CWH.
RESULTS: Mean follow-up was 18 months (range, 12-36). No side effects or toxic effects were documented. At 12-month follow-up examination, UCVAs (logarithm of the minimum angle of resolution) were 0.4+/-0.48 and 0.5+/-0.53 (P = .03) in mitomycin C-treated eyes and corticosteroid-treated eyes, respectively. At 1 year, corneal haze developed in 20% of corticosteroid-treated eyes, versus 0% of mitomycin C-treated eyes. At 12, 24, and 36 months, corneal confocal microscopy showed activated keratocytes and extracellular matrix significantly more evident in untreated eyes (Ps = 0.004, 0.024, and 0.046, respectively).
CONCLUSION: Topical intraoperative application of 0.02% mitomycin C can reduce haze formation in highly myopic eyes undergoing PRK.
