1. INFLUENCE OF SEED TUBE CURVATURE ON SEED LONGITUDINAL DISTRIBUTION
ABSTRACT Studies on the longitudinal distribution of seeds in the sowing row seek to improve crop homogeneity, thus generating high productivity. In this context, seed tubes must be analyzed for their angular curvature. Thus, this study aimed to evaluate the influence of the seed tube curvature on the longitudinal distribution of corn and soybean seeds at di

2. INTERFERENCE OF THE NUMBER OF REMOTE CONTROL VALVES IN USE ON THE ENERGY PERFORMANCE OF AN AGRICULTURAL TRACTOR WITH PRODUCTIVITY MANAGEMENT
ABSTRACT The hydraulic remote control system allows the transfer of energy from the engine through a flow of hydraulic oil to engines and implements pulled by agricultural tractors, which can interfere with its energy and operational performance. This study aimed to evaluate the interference of the number of remote control valves in use on the operational an

6. Randomized clinical study comparing active heating methods for prevention of intraoperative hypothermia in gastroenterology
RESUMO Objetivo: comparar a eficácia de três métodos de aquecimento ativo na prevenção da hipotermia intraoperatória em cirurgias gastroenterológicas por via aberta. Método: ensaio clínico randomizado com amostra de 75 pacientes, com temperatura corpórea inicial mensurada por termômetro timpânico. Considerou-se hipotermia a temperatura esofági

7. Variability, plot size and border effect in lettuce trials in protected environment
ABSTRACT The variability within rows of cultivation may reduce the accuracy of experiments conducted in a complete randomized block design if the rows are considered as blocks, however, little is known about this variability in protected environments. Thus, our aim was to study the variability of the fresh mass in lettuce shoot, growing in protected environm

8. Genotypic variation of traits related to quality of cassava roots using affinity propagation algorithm
The conservation, sustainable evaluation and use of cassava (Manihot esculenta Crantz) genetic resources are essential to the development of new commercial varieties. This study aimed to evaluate the quality of cassava roots and to estimate genetic variation and clustering in cassava germplasm using the Affinity Propagation algorithm (AP), which is based on

9. A morphometric study of the lumbar spinous process in the Chinese population
Our goal was to analyze the anatomical parameters of the lumbar spine spinous process for an interspinous stabilization device designed for the Chinese population and to offer an anatomical basis for its clinical application. The posterior lumbar spines (T12-S1) of 52 adult cadavers were used for measuring the following: distance between two adjacent spinous

10. Analysis of variance of primary data on plant growth analysis.
Plant growth analysis presents difficulties related to statistical comparison of growth rates, and the analysis of variance of primary data could guide the interpretation of results. The objective of this work was to evaluate the analysis of variance of data from distinct harvests of an experiment, focusing especially on the homogeneity of variances and the

11. Modelos de regressão PLS com erros heteroscedásticos
Two problems related to Partial Least Squares method are considered in this work. Heteroscedastic errors and an asymmetrical error distribution. In the _rst part of this work a methodology is developed which allows, based in PLS methods, to estimate the model parameters in the presence of non-constant error variance. This technique is compared with the usual

12. Diagnóstico de lesões da tireóide pela espectroscopia de absorção no infravermelho por transformada de Fourier-FTIR / Thyroid lesions diagnosis by fourier transformed infrared absorption spectroscopy (FTIR)
Thyroid nodules are a common disorder, with 4-7% of incidence in the Brazilian population. Although the fine needle aspiration (FNA) is an accurate method for thyroid tumors diagnosis, the discrimination between benign and malignant neoplasm is currently not possible in some cases with high incidence of false negative diagnosis, leading to a surgical interve
