Brazil has 8.1 million hectares dedicated to eucalyptus cultivation, establishing itself as the main forestry crop in the country. The wood produced from eucalyptus plantations is used for the paper and pulp industries, charcoal, wood panels, laminated flooring, sawn timber, cosmetics, and pharmaceuticals. In recent years, the intensification of climate change has been causing serious harmful alterations in soil and climate conditions worldwide, primarily resulting in changes in precipitation patterns and increased temperatures, expanding eucalyptus planting regions that are susceptible to water stress and posing a new challenge for forestry. Thus, the advancement of research to understand which plant mechanisms can be used for resilience to water stress becomes essential. Roots are essential for mechanisms of drought stress tolerance, as a robust root system can confer greater ability to capture water from the soil. The present study aimed to understand the feasibility of aeroponics as a suitable early screening method for identifying genotypes with superior root systems. Two clonal trials and one progeny trial were conducted, followed by the estimation of statistical and genetic parameters for root development traits using mixed linear models. The results reveal that there was a high mean heritability for progenies and clones, and moderate to high individual heritabilities in the progeny trial, indicating variability for individual selection in the progeny trial, with good capacity for estimating the combining ability of the parents, as well as a reliable estimation of the genetic values of the clones in the clonal trial. In this way, aeroponics has proven to be a viable phenotyping method for the identification and selection of superior clones and progenies for the root system, and it can be a practical and reliable tool for early phenotyping and selection of superior genotypes.

This undergraduate thesis comprises two main components: an undergraduate research project and a reflection on the author’s journey as a medical student, from admission to graduation, exploring how curricular and extracurricular experiences shaped his education. The research project aimed to assess the correlation between wrist circumference (WrC) and body mass index (BMI) z-score in elementary schoolchildren, with analyses stratified by sex and age, as an exploratory step for studies on the use of this measurement in the nutritional assessment of children. Childhood obesity is a major public health concern, and there is interest in simple, low-cost anthropometric measures that may complement its assessment. This cross-sectional, descriptive, quantitative study used a pre-existing database of 286 children of both sexes, aged 6–7 years, enrolled in municipal public schools in São Carlos, SP, Brazil. After excluding three children with WrC measurement errors and three with BMI z-scores above +5 (the WHO AnthroPlus flag limit), 280 were analyzed. The correlation between WrC and BMI z-score was estimated with Spearman’s coefficient. A statistically significant positive correlation of moderate to strong magnitude was observed in the total sample (ρ = 0.754) and in all subgroups (ρ = 0.692 to 0.811; p < 0.001). WrC thus showed a consistent anthropometric association with BMI z-score. However, because WrC was compared only with BMI, without a gold-standard measure of adiposity, metabolic outcomes, cut-off values or diagnostic accuracy analysis, the study cannot validate WrC as a screening tool for excess weight or metabolic risk; its findings support future studies with that purpose.

This study presents a reflective narrative on the author's personal experience with illness, medical treatment, and hospitalizations, which occurred concurrently with her seven years of undergraduate medical education at the Federal University of São Carlos (UFSCar). The author's experiences as a patient were varied, encompassing a diagnosis of epilepsy, recurrent tonsillitis, migraine attacks, and two hospital admissions — one resulting from sepsis and the other due to an anticonvulsivant medication toxicity presenting with encephalopathy. Through autobiographical accounts, this work reflects on the overlap between these health events and academic life, including participation in research projects, community outreach, and the cultivation of friendships, as well as the need for a medical leave of absence in 2024 due to her health condition. Furthermore, it highlights how the experience of being cared for reshaped the process of learning to provide care during medical training, fostering humanistic competence in medical practice and integrating technical knowledge with empathy, active listening, and critical reflection on practice. The study concludes that experiencing the vulnerability of being a patient provides a medical student with a deeper dimension of understanding, essential for cultivating a solid physician-patient relationship throughout their training.

In this thesis we study topics in Valuation Theory, with a particular focus on key polynomials, graded rings associated to valuations and the defect of a valued field extension. We first study, via direct limits, the graded ring associated to a valuation v that is an upper bound of an increasing family of valuations in the valuative tree. In particular, we describe the graded ring associated to a limit key polynomial via a direct limit of graded rings. We then parametrize subsets of the space of valuations using suprema of increasing families of valuations. These families are constructed from pseudo-Cauchy sequences and from approximation types. Finally, we study the defect of a valued field extension (L|K,v). We investigate the relationship between unibranched defectless valued field extensions and the complete sequences of key polynomials for the induced valuation on the polynomial ring K[x].

This study examined how data from the Diagnostic Assessment of the Municipal School System of Uberaba (MG), Brazil, can guide an intervention with mathematical games for learning recovery in the four fundamental operations in the 5th year. Using a qualitative approach supported by descriptive statistics, the study applied the games Magic Square, Zig-Zag, Five in a Row and Advancing with the Remainder in Class B, with “Bateu, respondeu!” as a complement; Class A served as a point of comparison. From the initial to the final stage, both classes had more problem-solving items rated satisfactory, although the items varied across stages. Division with remainders remained weak, especially in Class B. It is concluded that diagnostic assessment, combined with teacher mediation and games, can support learning recovery, although the results cannot be attributed to the games alone.
