Violence against women and girls is a serious human rights violation, reflecting gender inequality and impacting the health of victims. This study aimed to understand sexual violence against women and girls in Espírito Santo by analyzing SUS reports from 2017 to 2023. This study aimed to identify, in a comparative way, the factors associated with sexual violence in relation to other types of interpersonal violence against women and girls, describing singularities and intersections between victim profiles, contexts of occurrence and temporal trends, including possible impacts of the COVID-19 pandemic in Espírito Santo, between 2017 and 2023. The methodology consisted of a serial cross-sectional study using secondary data on reports of sexual violence and other interpersonal violence against women and girls in Espírito Santo. Data were collected from the Notifiable Diseases Information System (SINAN) for 2017–2019 and from the State Health Surveillance System (e-SUS VS) for 2020–2023. The analysis period covered three years before and three years after the first case of COVID-19 in the state. The results showed that, in Espírito Santo, among the women and girls reported for sexual violence, 69.9% were Black, 54.3% were under 14 years of age, 46.3% had less than 9 years of education, and 13.2% had some disorder or disability. Furthermore, 56.8% had no partner, 11.4% were pregnant, and 2.3% had accessed legal termination of pregnancy. The majority (86.5%) lived in urban areas, 71.1% in the Metropolitan Region, and 67.1% of the cases occurred in the victim's own residence, with 42.4% being repeat cases. The perpetrators were predominantly men (91.8%) over 24 years of age (51.8%), with 19.0% suspected of having consumed alcohol prior to the incident. Poisson regression analysis (PR; 95%CI; p < 0.001) revealed a high prevalence ratio for children up to 9 years old (PR=10.84) and adolescents aged 10 to 14 years old (PR=12.30), decreasing with increasing age (15-19 years: PR=6.89; 20-29 years: PR=2.73; 30-59 years: PR=1.71), reinforcing the robustness of the associations. In conclusion, Sexual violence against women and girls in Espírito Santo presents distinct patterns associated with gender inequality, invisibility, and the heightened vulnerability of children, adolescents, pregnant women, and persons with disabilities. The findings highlight the urgent need to strengthen the Violence and Accident Surveillance System (VIVA) through improved training, human resources, integration, and data quality to enhance the response of the SUS/ES to sexual violence.

This dissertation evaluates the technical feasibility of using ferronickel slag (FeNi) as a stabilizing agent and gradation corrector in two soils: a sandy soil (SL) and a silty fine soil (SR), with the aim of application in pavement layers. Mixtures with 30% and 60% FeNi, with and without 3% cement (CPIII and CFN50), were studied. The experimental program encompassed physical characterization (particle size distribution, specific gravity, organic matter content, Atterberg limits), chemical characterization (pH and cation exchange capacity), mineralogical characterization (XRF and XRD), and mechanical testing (compaction, California Bearing Ratio and swelling, as well as resilient modulus), with curing periods of 7 and 63 days. Results showed that FeNi is distinctly granular and of high density, shifting the mixtures towards a framework-controlled behavior and reducing plasticity, especially at 60% replacement. The SUCS, AASHTO and MCT classifications confirmed the trend toward more sandy materials. In compaction, the maximum dry unit weight increased, while the optimum moisture content decreased or remained stable with FeNi incorporation. The CBR increased significantly in SL mixtures with 3% cement, qualifying them as base course material, whereas pure SL and SL with FeNi but without cement met the requirements for subbase. In SR, relevant improvements occurred with FeNi, with or without 3% cement, placing the mixtures in the subbase category. Swelling remained very low in FeNi mixtures, complying with DNIT specifications. The resilient modulus increased with confining stress; in SR, the gain was governed by FeNi while cement had a secondary role, whereas in SL, cement was decisive and FeNi additionally contributed to the granular response. According to DNIT specifications, only SR+60%FeNi, with or without 3% cement, simultaneously met all requirements for subbase; considering only CBR and swelling, several SL formulations satisfied the base course criteria. It is concluded that FeNi is technically feasible as a component for base and subbase layers, with best performance at 60% content and in combination with low cement dosages, contributing to the valorization of by-products and to circular economy practices in pavement engineering.

This work presents a systematic study of complex numbers, ranging from their algebraic construction to some of their practical applications. It begins with formal definitions, properties, and geometric and trigonometric representations, emphasizing the role of complex numbers in extending the real number system. Subsequently, applications in engineering are discussed, particularly in the analysis of alternating current electrical circuits through phasor theory, which illustrates the importance of complex numbers in modeling oscillatory phenomena. In the context of trigonometry, the study demonstrates how the polar representation of complex numbers enables the proof of fundamental identities, such as addition formulas, while also providing an elegant method for calculating powers and roots. Finally, Cardano’s formulas for cubic and quartic equations are presented and examined. The work concludes that complex numbers, beyond extending the numerical structure of mathematics, possess an interdisciplinary character that bridges theory, practical applications, and the history of mathematics, thereby consolidating their role as an indispensable tool in scientific and technological development.

Mangroves are important carbon sinks, capable of sequestering and storing organic matter through its accumulation in both vegetation and soils. In Vitória Bay, these ecosystems face increasing pressures from mean sea level rise and urban expansion, which limits the landward migration of mangroves. This study was based on the hypothesis that mangroves located at lower elevations, due to their greater exposure to potential erosive processes and frequent inundation, would exhibit lower carbon stocks, as such processes could have removed part of the previously accumulated carbon and compromised their retention capacity. This study aimed to quantify total ecosystem carbon stocks in mangrove forests and to compare these stocks with coastal vulnerability indices in the metropolitan region of Vitória, southeastern Brazil. Total carbon stocks were quantified for six mangrove sites, including aboveground vegetation and soils down to 3 m depth. A guided classification of Vitória Bay was conducted to assess vulnerability based on spatial interpolation maps and the Coastal Sensitivity Index (CSI) developed by Machado and Albino (2024), which considers parameters such as overall vulnerability, elevation, geology/geomorphology, sedimentary features, and proximity to the coastline and river mouths.To compare with the CSI, in situ data on flood frequency and duration, water column depth, and elevation of the mangrove fringe (using RTK GPS) were collected at the six sampled sites. Our results showed that total carbon stocks in the six mangrove forests ranged from 717 to 1481 Mg C ha⁻¹, with an average of 1028 Mg C ha⁻¹, with over 90% of the carbon stored in the soils. The CSI indicated the sampled areas had high overall vulnerability, with site A classified as very high vulnerability, particularly due to its geology/geomorphology and sedimentary characteristics. In situ data classified site A as highly vulnerable, as it showed the lowest average elevation (-1.28 m), indicating greater exposure to flooding. Contrary to the initial hypothesis that mangroves in lower areas would have lower carbon storage capacity due to potential erosion, the lower areas of the Bay of Vitória showed the highest carbon stocks. This suggests that, even under greater physical vulnerability to these pressures, these mangroves continue to play a significant role in carbon retention, possibly due to soil accretion driven by aboveground plant material associated with root systems. This study indicates that, in the protected estuarine mangroves of Vitória Bay, carbon stocks are not primarily associated with vulnerability to coastal erosion related to wave action, highlighting the importance of integrating local hydrodynamic characteristics and terrain topography into conservation strategies and adaptive management in the context of climate change.

Proper management of pasture nutrition is essential for normal crop growth and development. Incorrect management of pasture nutrition makes crop areas susceptible to degradation, a common and prevalent problem in pasture-grown areas. Therefore, more efficient use of fertilizer nutrients becomes essential to increase productivity, plant quality, reduce nutrient losses through leaching, volatilization or immobilization, and improve sustainability in the agricultural sector. The objective of this study was to remotely monitor, through the use of vegetation indices, the vegetative development of pasture cultivated with different controlled-release fertilizers. The study was conducted in the experimental field of the Federal University of Espírito Santo (UFES), located in the municipality of Alegre, in a flat area cultivated with Tanzania grass (Panicum maximum cv. Tanzania). The experimental design of the study was a randomized block design (RBD), with a split-plot scheme in time, with two factors. The first factor (plot) involved four fertilization processes, two conventional (split - FCP and non-split - FCNP); two controlled release (non-split) and one control without fertilization. The second factor (subplot) consisted of four evaluation periods (pasture cuts) treated as subplots, in the pre-grazing simulated by mechanical mowing. From remote sensing and in loco evaluations, vegetation indices (NDVI, GNDVI, NDRE, MPRI, MSAVI, VARIG, EVI, CCCI and CI), apparent leaf chlorophyll indices and biometric variables, such as canopy height, fresh and dry mass, were calculated to monitor the effect of fertilizers. The results highlighted the similar performance between controlled release fertilizers (FLC) and conventional split fertilizer (FCP) in maintaining vegetative vigor and fresh and dry mass production of the pasture throughout the study period. Several vegetation indices showed significant correlation with the biometric variables collected in situ of canopy height, fresh mass, dry mass and apparent leaf indices of chlorophyll A, B and total of the pasture over time. The NDRE vegetation index was more sensitive and effective for monitoring and managing pasture fertilization, as it was able to detect, describe and be strongly correlated with the biometric variables collected in situ throughout all the studied cuts. The integration of FLC with vegetation indices proved to be a promising and effective approach for monitoring and sustainable management of pasture fertilization.
