1. Seguro contra risco de downside de uma carteira : uma proposta híbrida frequentista-Bayesiana com uso de derivativos
Seguros de carteiras proporcionam aos gestores limitar o risco de downside sem renunciar a movimentos de upside. Nesta dissertação, propomos um arcabouço de otimização de seguro de carteira a partir de um modelo híbrido frequentista-Bayesiano com uso de derivativos. Obtemos a distribuição conjunta de retornos regulares através de uma abordagem estat

2. The effect of positron emission tomography/computed tomography in axillary surgery approach after neoadjuvant treatment in breast cancer
SUMMARY OBJECTIVE: The aim of this study was to determine the role of positron emission tomography/computed tomography in the decision to perform axillary surgery by comparing positron emission tomography/computed tomography findings with pathology consistency after neoadjuvant chemotherapy. METHODS: Patients who were diagnosed for T1-4, cN1/2 breast cance

4. RING CURRENT IN ANTHRACENE AND PHENANTHRENE: CORRECTION TO HÜCKEL PARAMETERS
Excessive degeneracy in the ground state of the π-electron energy levels of anthracene was removed using the Hückel method by correcting the Coulomb integral of the four central carbon atoms. A further correction to the resonance integral was proposed based on the ring-current model, which describes the π-ring current flow along the molecule’s perimeter

5. Direct onion sowing under soil tillage methods
ABSTRACT Onion production is conditioned to the adopted techniques during the cultivation. Sowing depth, soil preparation and cultivars are determinant factors for productivity to be increased. Two experiments were developed, the first with the objective of evaluating the effect of sowing depths and soil preparation methods on the germination and development

6. Gas exchange and water stress index in soybean cultivated under water deficit and soil compaction
ABSTRACT Water stress is intrinsically related to soil water availability which is determinant in gas exchanges, as well as soil compaction in soybean growth and development. This study aimed to evaluate the leaf gas exchange, water stress index, and dry mass accumulation of soybean cultivated in different daily irrigation depths and bulk density. The treatm

7. Renal volume of five-year-old preterm children are not different than full-term controls
Abstract Objective: In previous studies, smaller renal volumes were reported in prematurely born infants, however, these renal volumes were not corrected for body surface area, the main determinant of renal size. Given the rapid growth of the renal cortex after premature birth, the authors hypothesized that corrected volumes would not differ from healthy co

8. Predicting latent classes of drug-related problems among adolescents: secondary analysis of a cluster randomized controlled trial
Objective: To detect latent patterns of drug-related problems and their predictors among adolescents. Methods: A three-wave randomized controlled trial was conducted among 6,391 7th and 8th graders (51.02% girls) at 72 public schools in six Brazilian cities to evaluate the #Tamojunto school-based drug prevention program. Patterns of drug use and behavior p

12. SHADING AS A DETERMINANT FACTOR FOR THE SURVIVAL AND GROWTH OF Cabralea canjerana IN SOUTHERN BRAZIL
ABSTRACT Plantations with native tree species, which emphasize biodiversity conservation, may not succeed because of a lack of forestry knowledge about the native species. Cabralea canjerana is an important tree species, which is rarely present in area restoration programs because of the difficulty in establishing it in plantations. Despite this, the species
