1. Dynamic anisotropy and non-linear geostatistics supporting short term modelling of structurally complex gold mineralization
Abstract Non-linear geostatistical methods are known to deal appropriately with the geological and geometrical complexity of gold deposits. This article reports the results related to an investigation to improve the gold content estimate based on restricted ore modeling to honor the structural aspects that control the mineralization. The grade domains are de

2. Increase in COVID-19 inpatient survival following detection of Thromboembolic and Cytokine storm risk from the point of admission to hospital by a near real time Traffic-light System (TraCe-Tic)
Abstract Introduction Our goal was to evaluate if traffic-light driven personalized care for COVID-19 was associated with improved survival in acute hospital settings. Methods Discharge outcomes were evaluated before and after prospective implementation of a real-time dashboard with feedback to ward-based clinicians. Thromboembolism categories were “medi

3. Emissões de poluentes atmosféricos em condições reais de pavimentação asfáltica: material particulado, black carbon e hidrocarbonetos policíclicos aromáticos
Intensive use of asphalt generates pollutants into the atmosphere which are harmful to the environment and worrying for occupational health. The application of asphalt products leads to emissions of significant concentrations of polycyclic aromatic hydrocarbons (PAHs) and particulate matter (PM) to the atmosphere. This paper aims to assess the pollutant emis

4. Analysis of neonatal mortality risk factors in Brazil: a systematic review and meta-analysis of observational studies
Resumo: Objetivo: Identificar, através de uma revisão sistemática e da metanálise de estudos observacionais, quais fatores de risco associam-se significativamente com a mortalidade neonatal no Brasil e construir uma análise nacional abrangente sobre a mortalidade neonatal. Fontes: Foram avaliados os estudos observacionais sobre mortalidade neonatal re

5. Spectral analysis in determining water quality sampling intervals
RESUMO Para gerar séries históricas de qualidade da água mais representativas desenvolvem-se técnicas de monitoramento em tempo real. Contudo, estas técnicas possuem obstáculos quanto ao uso: alto custo, dificuldades de instalação, manutenção e calibração dos equipamentos. Uma alternativa seria o chamado monitoramento da qualidade da água em tem

6. Improved Bayes estimators and prediction for the Wilson-Hilferty distribution
Abstract: In this paper, we revisit the Wilson-Hilferty distribution and presented its mathematical properties such as the r-th moments and reliability properties. The parameters estimators are discussed using objective reference Bayesian analysis for both complete and censored data where the resulting marginal posterior intervals have accurate frequentist c

7. A new class of lifetime models and the evaluation of the confidence intervals by double percentile bootstrap
Abstract: In this paper, we introduce a new three-parameter distribution by compounding the Nadarajah-Haghighi and geometric distributions, which can be interpreted as a truncated Marshall-Olkin extended Weibull. The compounding procedure is based on the work by Marshall and Olkin 1997. We prove that the new distribution can be obtained as a compound model w

8. Data assimilation using the ensemble Kalman filter in a distributed hydrological model on the Tocantins River, Brasil
RESUMO Neste trabalho, o método de assimilação de dados por filtro de Kalman por conjunto (EnKF) é aplicado na bacia do rio Tocantins. Esse método atualiza as vazões do rio usando um modelo hidrológico distribuído. O desempenho de EnKF é também comparado com um método de assimilação empírico a intervalos de tempo horário, onde duas aplicaçõ

9. Diseño y Evaluación de una Trayectoria Hipotética de Aprendizaje para Intervalos de Confianza basada en Simulación y Datos Reales
Abstract This article discusses the design of a hypothetical learning trajectory to introduce the confidence intervals in a basic university course, from an informal perspective based on the use of data obtained from surveys and samples simulation. The trajectory consists of four activities and was evaluated as part of a first improvement cycle with a group

10. Experimentation and modeling of soil evaporation in underground dam in a semiarid region
RESUMO Nas regiões semi-áridas, as altas taxas de evaporação interferem na disponibilidade de água no solo. Normalmente, é difícil medir e modelar a evaporação devido à complexidade dos métodos disponíveis, ao baixo teor de umidade do solo e à baixa concentração de vapor de água no ar. Isso também pode dificultar o monitoramento e a simula�

11. Different intervals of behavioral observation in the scanning method and the real behavior of pigs
ABSTRACT The objective of this work was to study the behavior of swine females in the grower phase using different observation intervals (continuous, 5, and 10 min). A total of 42 swine were used, 14 of them for each treatment, which were identified with a marker stick. These animals were observed using the focal sampling method for 5 h. The treatments were

12. Molecular response to imatinib mesylate of Brazilian patients with chronic myeloid leukemia
Abstract Background Imatinib mesylate has revolutionized the treatment of chronic myeloid leukemia leading to significant reductions of BCR-ABL1 transcript levels in peripheral blood. Objective To evaluate the response to imatinib mesylate treatment (400 mg/day) in Brazilian patients in the chronic phase of chronic myeloid leukemia monitored by quantitativ
