Abstract The presence of helminths and protozoans in public squares lawns the city Maringá, southern Brazil, during winter summer was assessed order to evaluate their seasonal fluctuations relation edaphic climatic factors. Samples were collected from January 2003 through June 2004 90% (13) all covered by sand, 30% (4) used as leisure areas. samples analysed quantitatively modified centrifugal-flotation sedimentation water techniques, qualitatively a method based on positive larval...

Abstract Thousands of women all over the world annually suffer vulvovaginal candidiasis (VVC), an infection caused by yeasts, which mainly affect mucosa vulva and vagina. The adherence yeasts to mucosae is essential step for colonization predisposes start infectious process. In this study, a technique capable evaluating adhesion human vaginal epithelial cells (HVEC) was employed. Twenty‐five yeast isolates (10 Candida albicans , nine C. glabrata two parapsilosis one tropicalis Saccharomyces...

This paper shows the Bayesian approach as an alternative to classical analysis of nonlinear models for ruminal degradation data. The data set was obtained from a Latin square experimental design, established testing dry matter, crude protein and fiber in neutral detergent three silages: elephant grass (Pennisetum purpureum Schum) with bacterial inoculant or enzyme-bacterial corn silage (Zea mays L.). incubation times were 0, 2, 6, 12, 24, 48, 72 96 hours. parameter estimates equations fitted...

The foremost factor necessary for plant growers cultivating large acreages of Stevia rebaudiana (Bert) Bertoni is the production qualitative bedding plants. objective this study was to evaluate influence osmotic-priming on uniformity seed germination. First, we evaluated percentage normal seedlings from two samples harvested in 2011 and 2012. seeds 2012 produced 71.4% thus they were used next experiments. subjected osmotic stress using five concentrations polyethylene glycol (PEG-6000) at...

Comparison between two distinct groups using a partial diallel and considering reciprocal effects has not been described in the scientific literature, limiting analysis results. This study compared of parents diallel, analyzed general specific combining ability effects, divided into maternal cytoplasmic. A was established with nine maize hybrids, including F1 hybrids for grain yield. For this application, were significant. The proposed model would provide plant breeders additional...

The experiment had the objective of fitting regression models to data height bedding plants cultivated in three multicellular Styrofoam trays with different cell volumes. We proposed two types current experiment. First, we fit a model normal errors and next skew-normal distribution errors. was suitable for modelling both cases. when included time covariate size part model. However, value parameter l multivariate very high, which is an indication that also not best. Thus, suggest further...

SUMMARY Analysing the stability and adaptation of cultivars to different environments is always necessary before recommending them for planting on large areas. Additive main effects multiplicative interaction (AMMI) models have been used analyse genotype-by-environment interactions (G × E). AMMI require data with homogeneous variance, normal errors additive effects. However, agronomic do not conform these statistical assumptions. The objective present study was G E severity incidence grey...

Este trabalho foi desenvolvido com o objetivo de ajustar um modelo regressão não-linear para estimar desempenho germinativo sementes três lotes comerciais milho híbrido OC 705, submetidas ao teste envelhecimento acelerado, à temperatura 43ºC. Utilizou-se logístico y(t)=C/(1+exp(B(t-M))) os dados. As medidas viés Box e curvaturas paramétrica intrínseca foram usadas diagnóstico do modelo. O proposto ajusta-se adequadamente aos dados percentuais germinativos todos lotes. Com base nas...

The objective of this analysis was to fit germination data Rhipsalis cereuscula Haw seeds the Weibull model with three parameters using Frequentist and Bayesian methods. Five parameterizations were compared a prior distribution. parameter estimates from method similar responses considering following non-informative priori distribution for vectors: gamma (10³, 10³) in M1, normal (0, 106) M2, uniform Lsup) M3, exp (μ) M4 Lnormal (μ, M5. However, achieve convergence models M5, we applied μ...

O cancro cítrico, causado pela bactéria Xanthomonas citri subsp. é uma das doenças mais importantes da citricultura. estudo condições de isolamento e manutenção isolados X. citri, o conhecimento sua exigência nutricional escolha um meio cultura eficiente para seu desenvolvimento imprescindível posteriores estudos in vitro, como no diversidade genética. Assim, objetivo deste trabalho foi avaliar a eficiência 8 diferentes meios na isolado proveniente pura (isolado Xcc 306) obtida junto ao...

Citriculture is one of the most important agricultural activities globally, with Brazil being leading world producers. Thus, such activity essential for country's economy and producers who depend on it. In this sense, fight against Huanglongbing, devastating citrus diseases caused by vector insects, to guarantee quality fruit avoid economic losses. The present work analyzed counting insect vectors in a commercial orange orchard an observational study carried out municipality Paranavaí, state...

In order to conduct a study on the effect of important design parameters in nickel desorption from macroalgae Sargassum filipendula, four agents were tested sets full 23 factorial designs (eluant agent, load, initial acid concentration and solid:liquid ratio). Two responses analyzed: amount desorbed for weight loss during process. The results showed that all factors significant both responses. Additionally, several interactions among also significant. Analyzing contribution each factor, it...

Giardia duodenalis cysts obtained from fresh fecal samples, samples kept under refrigeration and treated with formalin were studied as to their floatability on sucrose solutions the following specific gravities: 1,040 kg/m3; 1,050 1, 060 1,070 1,080 1,090 1,100 kgm3; 1,150 1,200 1,250 kg/m3, contained within counting-chambers 0.17 mm high. Cysts that floated those settled down sediments counted, had percentages estimated. Sucrose of kg/m3 gravity (the average diluting liquids employed in...

The effects of process variables on the oil extraction from passion fruit seeds by three techniques, ultrasound shaker, and soxhlet, environment-friendly solvents are evaluated. Ratio seed weight, solvent volume (R), time (T), type (S) were significant for R S shaker techniques T soxhlet extraction. Comparison showed that technique had highest yield with 65% total in initial matrix.

INTRODUÇÃO: Os portadores de doença Chagas frequentemente apresentam a hipertensão arterial sistêmica (HAS) como principal comorbidade. Em indivíduos hipertensos com e sem Chagas, o controle HAS geralmente é medicamentoso. Medidas alternativas intervenção exercício físico aeróbio têm sido preconizadas maneira mais efetiva para reduzir os níveis pressão arterial.OBJETIVO: Avaliar influência do sobre mulheres hipertensas Chagas.MÉTODOS: Dezenove voluntárias divididas nos grupos G1 (nove...

Attitudes related to the science of Statistics from Scientific Initiation Program students State University Maringa during 2000 are provided. Scale toward (SAS) and a questionnaire for additional information were used. Ninety-eight participated in sample. About 70% had already worked research projects. Most (75%) agree that needed work; 11.23% do not trust results; only 38.78% considered them important. Score average obtained by SAS reached 56.16 points (showing positive attitude). Reality...

In Brazil, the production of sweet oranges has been threatened by Citrus Variegated Chlorosis (CVC) incited gram-negative bacterium Xylella fastidiosa (Wells). Commercial citrus groves in two counties at Northwestern Paraná state were evaluated to estimate disease progression using parameterizations nonlinear models. Groves sinensis Osbeck, variety “Pêra”, “Valência”, “Natal” and “Folha Murcha” had all plants for presence symptoms. Thereafter, different Logistic Gompertz models fitted these...
