Exposure to Ultraviolet (UV-C) Radiation Increases Germination Rate of Maize (<i>Zea maize</i> L.) and Sugar Beet (<i>Beta vulgaris</i>) Seeds
No full textThis study investigated the effect of ultraviolet (UV-C) radiation on the germination percentage, germination rate, radicle length, and plumule length of maize and sugar beet seeds. The experiment was implemented in six replicates of 30 seeds per replicate and in sterilized petri dishes under laboratory conditions. Treatments included UV-C (254 nm) radiation exposure durations of 0 min (control), 30 min, 2 h, 4 h, 8 h, and 12 h. The UV-C radiation treatments did not significantly affect the germination percentage of the seeds (p < 0.05). However, the seeds germination rate was significantly affected by the UV-C radiation treatments. The treatments of 8 h and 12 h exposure duration led to the highest seed germination rates in maize and sugar beet, respectively. Lowest seed germination rates belonged to the controls. The radicle length of maize seeds was significantly affected by the UV-C radiation treatments, but the treatments did not significantly affect the radicle length of sugar beet seeds. The 12 h exposure to UV-C radiation treatment resulted in the largest radicle in maize, which was 2.08 cm larger than the radicle of the control seeds. The UV-C radiation treatments had a statistically significant effect on the plumule length of maize and sugar beet seeds. The treatment 8 h UV-C exposure duration led to the largest plumule in maize and sugar beet, which were 0.32 cm and 0.83 cm larger than the plumule of the control seeds, respectively. Breaking down the seed coat and increasing the temperature by UV-C radiation are potential reasons for the observed positive effects

Perspectivas de transcender na educação no trabalho: tendências da enfermagem latino-americana
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde. Programa de Pós-Graduação em Enfermagem.O objetivo deste estudo está em evidenciar as tendências de educação no trabalho na América Latina as quais estão sendo veiculadas nos periódicos de enfermagem, analisando-as crítica e reflexivamente. Na revisão da literatura utilizaram-se autores de diferentes áreas de atuação, em especial da enfermagem. A construção do referencial filosófico teve como base a Teoria Problematizadora de Paulo Freire e a Práxis de Adolfo Sánchez Vázquez, secundados por outros autores. Metodologicamente este estudo pode ser classificado como qualitativo, exploratório, com pesquisa documental. Para organizar os dados da pesquisa foi construído um software que permitiu o armazenamento de dados como: origem dos artigos publicados; formação, titulação e área de atuação dos autores; as revistas foram catalogadas pela denominação, número volume, ISSN, ano, mês e cidade em que foram publicadas. A pesquisa envolveu 18 periódicos que disponibilizam textos integrais e livres, com a revisão de 299 exemplares, 3310 de resumos e palavras chaves, dos quais foram retirados 70 artigos completos sobre a educação no trabalho de 07 diferentes países latino-americanos. Na contextualização do cenário do estudo evidenciaram-se pontos críticos na enfermagem, tais como: diversidade de formação, insuficiência quantitativa e qualitativa de pessoal, migração de enfermeiras, concentração em grandes centros urbanos. Estratégias de resolução a serem implementadas a médio e longo prazo são preconizadas na Agenda de Saúde para América-OPAS/OMS, associações profissionais e de classe, fundações filantrópicas, entre outras. No tratamento dos dados obtidos construíram-se seis categorias e as subseqüentes estruturas de resposta: as tendências de educação no trabalho, educação no trabalho e níveis de práxis, a educação no processo de trabalho na enfermagem, a educação no trabalho e a relação entre cuidar e educar, a educação no trabalho e a construção do conhecimento e a educação no trabalho na perspectiva do empoderamento dos sujeitos. Evidencia-se a possibilidade de transcendência em países como Brasil, Chile, Colômbia e México, em razão da amplitude das propostas de educação, embasamento em teorias educativas, formação, capacitação e titulação de recursos humanos, a articulação entre docência/serviços e as políticas de saúde. Na Argentina as ações educativas estão mais para a conservação em moldes tecnicistas. Em Cuba, a ênfase na obtenção dos resultados reforçam o tecnicismo com viés ideológico, enquanto que no Paraguai as propostas de educação no trabalho são praticamente incipientes. A construção desta pesquisa mostra que as possibilidades de transcendência estão na aproximação de teoria e prática, estruturação dos serviços, com propostas de educação no trabalho que permitam o empoderamento dos sujeitos. The objective of this study is to show the tendencies of education at work in Latin America which are linked with the Nursing periods, analyzing the critics and reflexive. In the revision of the authors literature different areas of actuation were used, especially nursing. The construction of philosophical references has as a base the Problematical Theory of Paulo Freire and the customs of Adolfo Sanchez Vasquez, supported by other authors. Methodologically this study can be classified as qualitative, exploratory, with documental study. To organize the data of the study a software was constructed that permits the storage of data like: the origin of articles published; formation, title and area of actuation of the authors; the magazines were cataloged by denomination, volume number, ISSN, year, month and the city in which they were published. The study involves 18 periods that permits a availability of integral texts and are free, with the revision of 299 examples, 3310 of abstracts and keywords, out of which 70 complete articles on education at work of 07 different Latin # Americans countries. In the contextualization of study scenario we can see the critical points of nursing, like: the diversity of formation, insufficient quantitative and qualitative of people, migration of nurses, concentration in grand urban centers. The strategy and resolution that are to be implemented in medium and long period are pre agenda in the Health Agenda for America # OPAS / OMS, professionals associations and the class, philanthropic foundations, among others. In the treatment of data obtained six categories are constructed and next structures of reply: the tendency of education at work, education at work and the level of the practice, education in the work process in nursing, education at work is the relation between care and educate, education at work is the construction of knowledge and education at work in the perspective of empowerment of people. As shown the possibility of transcending of countries like Brazil, Chile, Colombia and Mexico, in the light of the amplitude of the education proposal, based on educative theories, formation, capacity and titled of human resources, the articulation between docent/services and the health political. In Argentina the educative actions are more of conservation in technical model. In Cuba, the emphasis in obtaining of results reforces the technical with ideological line while in Paraguai the proposals of education at work are practicalment incipient. The construction of this study shows the possibility of transcendences are in the approximation of theory and practical, construction of services, with proposals of education at work that permits the empowerment of people
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe 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.
