1. Pre-copulatory bite wounds as evidence of aggressive competition for mating in the neotropical freshwater stingray Potamotrygon motoro
RESUMO Os aspectos reprodutivos das raias de água doce ainda são pouco estudados, no entanto, sabe-se que algumas espécies apresentam comportamento de cópula relacionado com as estações hidrométricas (águas altas e baixas). Com o intuito de avaliar as atividades reprodutivas que antecedem a cópula, nós examinamos as lesões por mordidas em Potamotr

2. What If the Forecaster Knew? Assessing Forecast Reliability via Simulation
ABSTRACT The FIFA Men’s World Cup (FWC) is the most important football (soccer) competition, attracting worldwide attention. A popular practice among football fans in Brazil is to organize contests in which each participant informs guesses on the final score of each match. The participants are then ranked according to some scoring rule. Inspired by these c

3. Industry Competition and Performance Persistence in Brazilian Equity Mutual Funds
RESUMO A indústria de fundos nacional, apesar de contar com um patrimônio cada vez mais elevado, se concentra em torno de poucas e grandes administradoras. Por isso, cabe questionar em que medida esse nível de concentração pode impactar o desempenho entregue ao cotista, pois a maior concentração implica em menor concorrência. Dessa forma, o objetivo

5. Osmotic dehydration kinetics of fresh and frozen blueberries considering volume shrinkage in a novel ternary solution
Abstract Osmotic dehydration is a nonthermal processing technology, that is limited in blueberries because of the osmotic agent, temperature and efficiency. This study was to prepare a novel ternary solution considering low-sugar, low-salt and low-viscosity requirements and to dehydrate blueberries at 20 °C. The mass transfer kinetics of fresh and frozen bl

6. Genetic parameters estimation in common bean under weed plant competition
ABSTRACT The present study aimed to estimate genetic parameters of 20 common bean genotypes, commercial and regional bean on weed interference. The agronomic characters analyzed were: average stem diameter (ASD); average plant length (APL); number of pods per pot (NPP); number of locules per pod (NLP); number of grains per pod (NGP); percentage of empty locu

7. Perovskite-Type Oxides La0.6M0.4Ni0.6Cu0.4O3 (M = Ag, Ba, Ce) towards the Oxygen Reduction Reaction (ORR) in Alkaline Medium: Structural Aspects and Electrocatalytic Activity
In this work, La0.6M0.4Ni0.6Cu0.4O3 (M = Ag, Ba, and Ce, denoted as LANC, LBNC, and LCNC, respectively) electrocatalysts were synthesized by the Pechini method at 1023 K for two hours in air. Rietveld refinement allowed the identification of the crystallographic phases present in all oxides. The electrocatalytic performance of these oxides towards the oxygen

8. Effect of high temperature and recovery from stress on crop–weed interaction
ABSTRACT Biotic and abiotic stresses, either individually or in combination, may affect soybean growth and development negatively, besides competitiveness with weeds. This study aimed at evaluating the effect of heat stress and plant recovery on crop–weed interaction by analyzing growth variables. Experiments were set up as replacement series of soybean wi

9. Signaling Honesty: Institutional Strength and Voters’ Concern About Corruption in a Model of Electoral Competition
Resumo Quando os eleitores se preocupam com a honestidade de seus líderes políticos, políticos office seekers — sejam corruptos ou não — têm fortes incentivos para se comportar como se fossem realmente honestos. Construímos um jogo simples de sinalização no qual o político no poder desconhece a parcela do eleitorado que se preocupa com a corrup�

10. Comparative study of inclusion removal from liquid steel in the RH and argon purging processes
Abstract In order to improve steel quality, it is necessary to increase the cleanliness of the liquid steel; that is, to reduce the number and size of the inclusions in the liquid steel, as well as to control their chemical composition. For this purpose, processes (with different operating costs) are used, such as the bubbling of inert gas in the steel ladle

11. REMEDIACIÓN ELECTROCINÉTICA DE UN SUELO REAL CONTAMINADO CON PLOMO ASISTIDA CON LA ADICIÓN DE UN AGENTE COMPLEJANTE
The use of ethylenediaminetetraacetic acid disodium salt (Na2EDTA) as a chelating agent presents ideal characteristics to be used for the removal of lead from a contaminated site. Batch experiments together with a simple local equilibrium model were carried out to evaluate the role of EDTA as enhancing agent in electrokinetic remediation of a Pb-contaminated

12. HOW COMPETITION INDICES BEHAVE AT DIFFERENT NEIGHBORHOOD COVERAGES AND MODIFICATIONS IN A NATURAL ARAUCARIA FOREST IN SOUTHERN BRAZIL
ABSTRACT Tree-level growth models are being more used in heterogeneous forests, for they can take underlying processes, such as competition, into account. Although it is common in the forest literature to test several indices in order to define the most suitable for each study, the evaluation of plot sizes or competition radii is poorly addressed in competit
