2. Physiology of the forage cactus cultivate Opuntia stricta (Haw.) Haw under different irrigation frequencies in the Semiarid
ABSTRACT The objective of this work was to evaluate the physiological variables of the cultivar Opuntia stricta (Haw.) Haw in the first cycle and in the regrowth, under different frequencies of drip irrigation, cultivated in the Agreste da Paraíba mesoregion. Therefore, a randomized block design was used, with 2 treatments (irrigation frequencies) and 4 rep

3. Flexible pavement with mining waste proposal - execution and analysis of an experimental section
Abstract The extraction of iron ore has a fundamental role in the Brazilian economy. However, such activity generates considerable volumes of waste whose disposal, even if regulated and licensed, has a significant environmental impact. The worldwide concern for sustainable practices along with the urgency for measures to mitigate environmental damage, justif

4. Optimum design of steel columns filled with concrete via genetic algorithm: environmental impact and cost analysis
Abstract The use of concrete-filled tubular columns as part of structural systems has steadily increased throughout the years. The growing demand for structural elements of this nature is a direct result of the possibility to use various cross-section shapes that have increased strength, along with resistance to fire and other corrosive agents. The main obje

5. Impact of Air Pollutant on Heart Rate Variability in Healthy Young Adults
Abstract Background: Air pollution and sex independently affect cardiac autonomic control, which can be assessed by heart rate variability (HRV). The research hypothesis is that individuals exposed to low concentrations of pollution have higher cardiac autonomic modulation compared to those exposed to high concentrations and that women have better cardiac a

6. Offspring of mothers with bipolar disorder: a systematic review considering personality features
Objective: To examine personality/temperament features and mental health vulnerability in offspring of mothers with bipolar disorders (BD), including dimensions which may impact psychological characteristics or therapeutic measures. Methods: A systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidel

7. Microplastics in Latin America Ecosystems: A Critical Review of the Current Stage and Research Needs
The ubiquity of microplastics ecosystems has gained global attention. In this context, Latin America, which is responsible for 8% of the world’s consumption of plastic material and has a small recycling rate (4.5%), does not have enough data on microplastics contamination in its environmental matrices. This systematic review analyzed 196 studies from 16 te

8. Agro-Industrial Waste Valorization: Transformation of Starch from Mango Kernel into Biocompatible, Thermoresponsive and High Swelling Nanogels
Mango industry processing disposes 40-60% of this fruit as residues, such as peels and kernels. The exploration of bioproducts from these industrial rejects can reduce environmental impact besides of producing high value-added materials. In this scenario, carboxymethyl starch nanoparticles were produced from mango (Mangifera indica L.) kernel starch. These n

9. Utilization of the Corncob Agro-Industrial Residue as a Potential Adsorbent in the Biosorption of Bisphenol-A
The presence of plastic waste in water bodies has led to a growing concern due to the impact on human health. Among the most important plastic additive molecules is bisphenol-A (BPA). On the other hand, micro-pollutant removal processes that make use of agro-industrial waste have aroused the interest of researchers. This is because the accumulation of lignoc

11. COMPARAÇÃO DE MÉTODOS PARA DETERMINAÇÃO DE SUBSTÂNCIAS HÚMICAS EM FERTILIZANTES LÍQUIDOS COMERCIAIS
The beneficial effects of humic substances (HS) on crop development have been evidenced in the last decade, leading to the commercialization of HS products with fertilizing properties. Currently, three methods are frequently used for HS determination: method described in the manual of the Brazilian Ministry of Agriculture, Livestock and Supply (MAPA); method
