Rio Jacutinga - Coronel Vivida/PR: qualidade da água para abastecimento público da área urbana
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em Geografia.Buscou-se com esta pesquisa analisar a qualidade da água do rio Jacutinga. Atualmente a SANEPAR utiliza água de dois rios para abastecer a população da cidade de Coronel Vivida/PR, do Jacutinga, captada desde 1981 e do Barro Preto, captada desde 1977. Como o rio Barro Preto possui uma capacidade relativamente pequena para abastecimento, a SANEPAR aumentará a captação do rio Jacutinga, cuja bacia possui uma área de 186 Km2, para depois que a nova ETA (estação de tratamento de água) for construída, torná-lo praticamente a única fonte de abastecimento de água para quase 18 mil pessoas na cidade de Coronel Vivida. A área de estudo caracteriza-se por ser predominantemente agrícola, sendo cultivados principalmente soja, milho e feijão. Além disso, é praticada a pecuária extensiva de gado bovino. A quantidade de suínos não é significativa. Elaboraram-se diversos mapas para a representação e melhor visualização de alguns elementos da bacia, tais como planialtimetria e hidrografia, hipsometria, declividade e uso do solo. Foram realizadas 12 amostragens de água, no período de setembro de 2005 a agosto de 2006, na captação de água da SANEPAR e foz do rio e em uma das nascentes principais - "ponto branco", para fazer a comparação entre eles. Foram analisados 23 parâmetros, enquanto que a SANEPAR analisa somente 4 parâmetros para a realização do tratamento da água. Alguns resultados dos parâmetros físicos, químicos e biológicos estiveram mais baixos, outros iguais, enquanto outros estiveram acima dos valores obtidos no ponto branco. Nas análises referentes a agrotóxicos apenas trihalometanos foram detectados em algumas das amostragens. Trabalhou-se também com os resultados das análises realizadas pela SANEPAR a cada 2 horas, da água bruta que chegava a ETA para ser tratada, e, com aqueles das análises realizadas após o tratamento da água. Um dos problemas que afeta a qualidade da água é o fato de a vegetação ripária ou mata ciliar, tanto nas nascentes como ao longo do rio ser muito pobre ou inexistente. Os órgãos responsáveis tais como Prefeitura Municipal e SANEPAR devem tomar providências para que a legislação seja cumprida e a mata ciliar seja preservada e que, além disso, as atividades desenvolvidas na bacia se dêem de maneira sustentada, evitando a degradação das condições da bacia, bem como da qualidade da água do rio

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
Data associated with the publication: Recalde-Coronel G. C. et al. (2024) Contributions of initial conditions and meteorological forecast to subseasonal-to-seasonal hydrological forecast skill in western tropical South America. Journal of Hydrometeorology
No full textThis archive contains data used in the publication Recalde-Coronel G. C. et al. (2024).
The sub-seasonal to seasonal hydrological forecast systems (S2S-HFS) dataset contains monthly spatial meteorological forcing fields (e.g., Tair, Qair, Rain) and hydrological variables (e.g., evapotranspiration, surface runoff) for Western Tropical South America (WTSA) for ten ensemble members. WTSA includes Peru, Ecuador, Colombia, and portions of Venezuela, Brazil, Bolivia, and Chile. We conducted the S2S-HFS hindcast simulations from 2000 to 2017 using the Noah-Multi-parameterization (Noah-MP) land surface model in offline mode within NASA’s Land Information System. The S2S-HFS hydrological simulations consist of daily outputs at 10-km spatial resolution over WTSA (1°N–18°S, 82°–67°W). The S2S-HFS is run using the downscaled NASA Goddard Earth Observing System Model - sub-seasonal to seasonal (GEOS-S2SV1) dataset as a meteorological forcing, and the Western Tropical of South America Land Data Assimilation systems (WTSA-LDAS; Recalde et al. 2021) retrospective simulation dataset as initial conditions. Further details of the S2S-HFS methodology are provided in Recalde-Coronel et al. (2024).
Code for the NASA Land Information System used to generate these model outputs is maintained by NASA and is available at https://github.com/NASA-LIS/LISF.

Dynamics of supercoiled DNA with complex knots: Large-scale rearrangements and persistent multi-strand interlocking
No full textKnots and supercoiling are both introduced in bacterial plasmids by catalytic processes involving DNA strand passages. While the effects on plasmid organization has been extensively studied for knotting and supercoiling taken separately, much less is known about their concurrent action. Here, we use molecular dynamics simulations and oxDNA, an accurate mesoscopic DNA model, to study the kinetic and metric changes introduced by complex (five-crossing) knots and supercoiling in 2 kbp-long DNA rings. We find several unexpected results. First, the conformational ensemble is dominated by two distinct states, differing in branchedness and knot size. Secondly, fluctuations between these states are as fast as the metric relaxation of unknotted rings. In spite of this, certain boundaries of knotted and plectonemically-wound regions can persist over much longer timescales. These pinned regions involve multiple strands that are interlocked by the cooperative action of topological and supercoiling constraints. Their long-lived character may be relevant for the simplifying action of topoisomerases

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.
