13. Genetic improvement of silage maize: predicting genetic gain using selection indexes and best linear unbiased prediction
RESUMO O objetivo deste trabalho foi avaliar quatro índices de seleção e o método BLUP na predição de ganhos genéticos em híbridos de milho para silagem. Foram comparados quatro índices de seleção e o método BLUP na predição de ganhos genéticos. Foram avaliados 19 híbridos topcrosses, e cinco testemunhas em delineamento experimental de blocos

14. Is thyroid nodule volume predictive for malignancy?
ABSTRACT Objective: We aimed to determine the roles of preoperative thyroid nodule diameter and volume in the prediction of malignancy. Subjects and methods: The medical records of patients who underwent thyroidectomy between January 2007 and December 2014 were reviewed. The nodule diameters were grouped as < 1 cm, 1-1.9 cm, 2-3.9 cm and ≥ 4 cm, and volu

15. Propagation of bichromatic-bidirectional waves
RESUMO Este trabalho tem por objetivo investigar as transformações sobre o nível médio da água e o tensor de tensão de radiação durante a propagação de ondas Bicromáticas e Bidirecionais (Bi-Bi) em um talude 1:22 e profundidades variando de 55 cm a 26 cm, simulando uma bacia de ondas em laboratório. Um modelo matemático escrito em Python foi ut

16. Robust volumetric models for supporting the management of secondary forest stands in the Southern Brazilian Atlantic Forest
Abstract The majority of Atlantic Forest fragments in Southern Brazil are second-growth forests dominated by fast-growing species with considerable market-value timber. Nevertheless, volume prediction models are scarce, especially to estimate tree total volume (i.e., stem plus branches). This study approached the issue through the following aims: to fit and

17. Repeatability coefficients and genetic gains in table grape progenies for the Brazilian semi-arid region
ABSTRACT: Table grape stands out among the main fruit-bearing plants of irrigated agriculture in the São Francisco Valley region of Brazil. This study estimated repeatability and heritability coefficients and predicted genetic gains in order to select superior genotypes in grape progenies from controlled hybridizations using the Restricted Maximum Likelihoo

18. Remote Sensing and Geostatistics Applied to Post-stratification of Eucalyptus Stands
ABSTRACT Brazil has many rural properties with unmanaged eucalyptus stands. These plantations are heterogeneous, presenting different tree sizes, advanced ages, and large wood volumes that can be quantified using forest inventories. The prediction error of dendrometric variables, mainly in highly heterogeneous areas, can be associated with inadequate forest

19. Prediction System for Diameter Distribution and Wood Production of Eucalyptus
ABSTRACT The aim of the present study was to propose a prediction system to estimate the diameter distribution and wood production in unthinned eucalyptus clone plantations. Data was obtained from permanent sample units, with ages from 28 to 78 months. The Weibull distribution was used to estimate the frequency of the number of trees per diameter class. Mod

20. Tree community variation in a tropical continental island according to slope aspect and human interference
ABSTRACT Associating description of unrecorded tropical tree community structure to sampling approaches that can help determine mechanisms behind floristic variation is important to further the comprehension of how plant species coexist at tropical forests. Thus, this study had the goals of (i) evaluating tree community structure on the continental island of

21. Expression of serum microRNA-378 and its clinical significance in renal cell carcinoma
Abstract Studies have demonstrated that miRNA-378 is expressed in various malignant tumors. In the present study, we aimed to explore the expression of serum miRNA-378 and its clinical significance in renal cell carcinoma (RCC) patients. A total of 75 RCC patients, 63 renal cysts (RC) patients and 75 healthy controls were selected. The miRNA-378 level in RCC

22. NUMERICAL PREDICTION OF BUBBLE SIZE AND INTERFACIAL AREA CONCENTRATION IN THE LIQUID BATH OF AN ENTRAINED-FLOW COAL GASIFIER
Abstract A CFD-ABND coupling model was used to study the flow characteristic of gas-liquid two-phase flow in the process of gas passing through the liquid bath of a water-coal-slurry entrained-flow gasifier. In this model, an average bubble number density (ABND) approach was employed and merged with the two-fluid model. A two-phase version of the RNG k-ε tu

23. Application of artificial neural networks in indirect selection: a case study on the breeding of lettuce
The efficiency of artificial neural networks (ANN) to model complex problems may enable the prediction of characteristics that are hard to measure, providing better results than the traditional indirect selection. Thus, this study aimed to investigate the potential of using artificial neural networks (ANN) for indirect selection against early flowering in le

24. Acrylamide inverse miniemulsion polymerization: in situ, real-time monitoring using nir spectroscopy
In this work, the ability of on-line NIR spectroscopy for the prediction of the evolution of monomer concentration, conversion and average particle diameter in acrylamide inverse miniemulsion polymerization was evaluated. The spectral ranges were chosen as those representing the decrease in concentration of monomer. An increase in the baseline shift indicate
