Summary: Brazil is an important source of arbovirus diversity, particularly in the Amazon region. The Atlantic Forest, including Vale do Ribeira in the Southeastern region, may also be a hotspot for emerging viruses like Bunyaviruses. A new isolate of Bruconha virus (BRCV) was recently obtained in Iguape city, showing high genetic variations compared to a prototype isolated 35 years earlier. This finding emphasizes the need for continued surveillance and genomic studies in the area.

Summary: Most water bodies are currently facing pollution from industrial and domestic sectors. The Biobio river is under various anthropogenic pressures, including industrial water supply, drinking water, hydroelectric power generation, agriculture, and industrial and urban waste. A water quality model was used to determine the Biological Oxygen Demand Loading Capacity in a basin with limited water quality data under strong anthropogenic pressures, showing a high carrying capacity in the studied section of the river.

Summary: This study investigates the role of natural resources, digitalization, governance, and economic growth in improving the load capacity factor (LCF) of high-resource-consuming economies. The long-run results reveal that reliance on natural resources and economic growth reduce LCF, while digitalization and good governance improve LCF.

Summary: The Vale do Ribeira in southeastern Brazil is known for its many caves containing osteological material, including remains of several extinct species such as the sabertooth cat Smilodon populator. A specimen found in the Abismo Ponta de Flecha Cave represents one of the smallest ever found specimens of S. populator, comparable in size to an adult lion.

Summary: Research conducted in the Ribeira do Iguape Valley watershed in Brazil revealed low concentrations of arsenic and lead in water samples, which were within Brazilian regulatory limits, but elevated levels of these elements were found in sediment samples. Arsenic showed higher mobility in sediment, while lead was mostly bound to the sediment matrix.

Summary: With concerns about environmental issues increasing, attention has shifted to the utilization of limited materials supplies. Rapid economic growth heavily relies on resource use, leading to reduced biodiversity and ecological footprints. Scholars and policymakers are actively seeking approaches to improve environmental load capacity without hindering economic growth. This research analyzes the effect of digitalization, natural resources, GDP, globalization, and governance on the improvement of load capacity in selected economies. The findings suggest that dependence on natural resources, globalization, and economic growth diminish load capacity, while digitalization and sound governance bolster it. The study recommends financial and policy support for initiatives such as zero-emission vehicle production and energy-efficient building construction to attract domestic and private investors through low-interest credit.

Summary: Recently, carbon emissions and ecological footprint have been criticized for being used as substitutes for assessing pollution in some empirical studies. This study differs from previous research by utilizing load capacity factor (LF) as a measure of ecological quality. LF takes into account both the demand and supply sides of nature, providing a comprehensive evaluation of ecological quality through the analysis of ecological footprint and biocapacity.

Summary: The study developed an analytical model to predict the load-carrying capacity of CLT walls under combined out-of-plane bending and compression loads, proposing an explicit formula based on compression failure mode for accurate predictions. This model considers the distribution of rolling shear stress, rolling shear-induced axial force, and moments in CLT beam-columns, and shows good agreement with test results.

Summary: India's decision not to reduce coal consumption at COP26 highlights the importance of analyzing environmental quality. This study examines the impact of human capital, geopolitical risk, globalization, natural resources, urbanization, and income on the country's load capacity factor (LCF) under the load capacity curve (LCC) hypothesis. The results show that natural resource rents, human capital, and globalization support environmental quality improvement, while urbanization has a negative impact on LCF and geopolitical risk has no effect. The study also finds that the LCC hypothesis is valid for India and that the Kyoto Protocol has a short-term negative impact on LCF but no long-term environmental impact.

Summary: Project portfolio networks (PPNs) are becoming more interdependent to achieve enterprises' strategic objectives. However, these interdependencies increase the potential for risk cascading propagation, which can lead to the collapse of the entire PPN. To maintain PPN robustness and controllability, a risk cascading propagation model is developed using a load capacity model. The results show that the proposed model can improve the robustness and controllability of the PPN, providing a basis for risk management in a specific context.

Summary: Oxide-rich materials like red mud are efficient adsorbents for soil pollutants, with an evaluation of sorption reactions of selected cations/anions on aluminum-mining by-product proposing a new distribution constant to assess sorption efficiency. Anionic adsorbates showed higher affinity for the by-product than cationic ones, with lead and copper being more adsorbed compared to zinc and cadmium.

Summary: The study evaluated the impact of different use and management systems on the physical quality and total organic carbon content of Haplic Ferralsols (Densic) in northeastern Brazil. Agroforestry systems, specifically those 7 and 12 years old, showed the best soil structure-related variables for maintaining or regenerating soil aggregation. Overall, agroforestry systems had less impact on physical soil quality parameters compared to conventional planting and pasture systems.

Summary: Changes in land use in riverside ecosystems affect the spatial variability of soil physical-mechanical attributes, especially during the rainy season. This study evaluated the impact of cultivating banana trees on the spatial variability of these attributes in riparian zones of the Ribeira de Iguape River in Brazil. The results showed that flood conditions increased the spatial variability of soil attributes, and soil closer to the water body was more affected.

Summary: This study evaluated the impact of nitrogen fertilizer application on soil CO2, CH4, and N2O emissions during different stages of banana cultivation. The results showed that nitrogen fertilization increased N2O emissions, especially in young banana plantations. Additionally, banana plantations showed lower CH4 uptake compared to the forest remnant. Therefore, reducing nitrogen application rates should be considered in young banana plantations due to the negative effect of N2O emissions.
