1. The Harbin Medical University nephrectomy score: a quantitative system for evaluating the complexity of laparoscopic retroperitoneal simple nephrectomy
ABSTRACT Background: Laparoscopic retroperitoneal simple nephrectomy (LRSN) has been widely accepted as a mainstay option for benign non-functioning kidney. The complexity of the procedure, however, differs and remains a subject of controversy. Objective: To develop a standardised Harbin Medical University nephrectomy score (HMUNS) system for evaluating LR

2. Habitat structure and their influence in lizard’s presence
Abstract Many species are declining due to environmental and physical changes in their habitats. Such disturbs alter the availability of micro-habitats and influences the presence of lizards, being even worse for threatened and endemic species. Glaucomastix littoralis is a teiid species restricted to four restingas areas of Brazil. The understanding about th

3. Estimativa da resistência característica à tração da madeira na direção paralela às fibras por meio de modelos probabilísticos
RESUMO Para um dimensionamento de estruturas de madeiras dentro das exigências de segurança, a resistência para determinada solicitação mecânica é calculada com base em seu valor característico, correspondente ao percentil de 5% de um determinado modelo de distribuição de probabilidades. A norma brasileira NBR 7190 [1] estabelece, para pequenas amo

4. Uncertainty estimation in hydrodynamic modeling using Bayesian techniques
RESUMO A avaliação de incertezas tem emergido como estudo primordial para se conhecerem os efeitos dos erros inerentes aos processos de modelagem de perfis de escoamento de vazões de cheia, de natureza aleatória e epistêmica, presentes em dados de entrada como vazões e topobatimetria, na estrutura e parametrização dos modelos matemáticos utilizados

6. Adaptive Filtration of Parameters of the UAV Movement Based on the TDOA-Measurement Sensor Networks
ABSTRACT: In modern conditions unmanned aerial vehicles (UAVs) generate new classes of threats, including their use for terrorist purposes. A feature of modern UAVs is the ability to perform sudden maneuvers and to keep the same position in the point in space. For the description of the UAV movement with various types of maneuver it is used a rectangular coo

7. COMPETITION POLICY EVALUATION THROUGH DAMAGE ESTIMATION IN FUEL RETAIL CARTEL IN LONDRINA, BRAZIL
RESUMO Este trabalho estima os danos causados pelo cartel nos postos de gasolina na cidade de Londrina, Paraná, na região sul do Brasil, usando tanto uma equação, quanto um modelo estrutural de demanda e oferta. Documentos do Conselho Administrativo de Defesa Econômica (CADE) ajudam a caracterizar os postos envolvidos na colusão nos mercados de etanol

8. NPV analysis of multiple surface constraints for pit expansion scenarios under geological uncertainty
Abstract To optimize a mining project, it is necessary to deal with several technical aspects and constraints, such as orebody modelling, reserve estimation, blending strategy, optimal and operational pit designs, cost control, environmental issues, among others. In this sense, locating surface infrastructures is one of the most critical mine planning concer

9. ESTIMATION OF THE CHARACTERISTIC VALUE OF WOOD STRENGTH
ABSTRACT For safety reasons, wood strength values, essential for structural dimensioning, are calculated based on the characteristic value, which corresponds to the 5% percentile of a given probability distribution model. For small samples, the Brazilian normative document ABNT NBR 7190 establishes an estimator of the characteristic wood strength, which can

10. Measurement uncertainty of plane-strain fracture toughness KIC testing by the Monte Carlo Method
Abstract The reliable determination of materials' mechanical properties is a fundamental factor for their application in engineering, and the estimation of the measurement uncertainty in testing laboratories has a direct impact on the interpretation of the results. Recent literature demonstrates that one of the most widely used methodologies for uncertainty

11. OAB score: A clinical model that predicts the probability of presenting overactive detrusor in the urodynamic study
ABSTRACT Purpose To create a predictive model of involuntary detrusor contraction (IDC) to improve the diagnostic accuracy of overactive detrusor (OAD), associating overactive bladder (OAB) symptoms with other clinical parameters in the female population. Materials and Methods A total of 727 women were studied retrospectively. In all of them, urodynamic st

12. Error variance of short duration sieving
Abstract In this study, the variance of ordinary sieving test error was determined concerning the specification limit of sized iron ore product by subtracting the fundamental error (described by the Gy's formalism for sampling), from the global error (recoverable from database of historical values). The results allowed the calculation of the confidence inter
