Use of generalized additive mixed models in the comparison of mortar types in d...

Generalized additive mixed models (GAMM) are useful when the nature of the data is longitudinal, which include the nonlinearity of the individual trajectories of the subjects, associating these with the assumption of the existence of random effects for each individual. In these models it is possible to rewrite the predictor as a sum of smooth nonparametric functions and then use the smooth technique P-spline. T...

Biological activities of basil essential oil: a review of the current evidence

Currently, natural products are being used as a therapeutic alternative in the treatment and prevention of several diseases due to their low toxicity and relevant pharmacological potential. Thus, we can highlight basil (Ocimum basilicum L), one of the most used aromatic plants worldwide. Therefore, we provide some current evidence and insight into the potential therapeutic effect of basil essential oil to expan...

Modeling citrus huanglongbing data using a zero-inflated negative binomial dist...

Zero-inflated data from field experiments can be problematic, as these data require the use of specific statistical models during the analysis process. This study utilized the zero-inflated negative binomial (ZINB) model with the log- and logistic-link functions to describe the incidence of plants with Huanglongbing (HLB, caused by Candidatus liberibacter spp.) in commercial citrus orchards in the Northwestern ...

Pesticide use and cholinesterase inhibition in small-scale agricultural workers...

Realizou-se um estudo transversal controlado, com hortifruticultores, durante o período de outubro de 2009 a outubro de 2010, a fim de caracterizar o uso de praguicidas, estabelecer o perfil sócio demográfico e analisar a atividade das colinesterases em trabalhadores rurais do sul do Brasil. Os dados foram obtidos de 173 trabalhadores e 179 controles. Um formulário estruturado foi aplicado obtendo informações s...

Adult carbohydrate feeding affects reproduction of Phthorimaea operculella (Zel...

Variables associated with the post-treatment healing of lesions in patients wit...

The purpose of this study was to investigate the relationship of several variables to the healing of lesions in patients with American cutaneous leishmaniasis (ACL). The patients with clinical and/or laboratorial diagnoses of the disease were followed up for varying periods after treatment by clinical evaluation and indirect immunofluorescence assay (IFA), from September 2000 to December 2003. The lesions of 85...

A study about the size of the sample and the supervision of production of the s...

The quality of the silk thread produced by Cocamar is evaluated through the following characteristics: rupture, cleaning, purity, evenness variation I, II and III, title deviation, maximum deviation, conditional title, tenacity and elongation. The objectives of this study had been: to verify if the sample and lot formation are in agreement the statistical methodology and the quality control; to verify if the ma...

Estimate of the condition factor of fish of the Tracydoras paraguayensis specie...

The factor of fish condition expresses the weight-lengthrelationship and it is accepted as an indicator for the evaluation of the animal "well-being";as larger the weight, best should be your survival condition. This work aims to fit a Gammamodel, from the exponential family with power link function, to data of lengthmeasurements and weight of fish from the Trachydoras paraguayensis species, observed in thebasi...
