5. 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

6. 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

7. Nitrogen Oxides Levels in the Atmosphere of Different Brazilian Urban Centers, by Passive Sampling
Urban air pollution is still an emerging environmental problem, it causes damage to health and is difficult to be controlled in urban centers. The population of large metropolises is often exposed to concentrations of nitrogen oxides (NOx), mainly due to vehicle emissions. Epidemiological studies claim that exposure to these oxides is strongly correlated wit

9. 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

10. Selective formation of neodymium phosphate from iron-neodymium magnet waste
Abstract Neodymium-iron-boron alloy, Nd2Fe14B, is used as a material for magnets. Neodymium is one of the valuable and expensive rare earth elements and is often recovered to reduce costs and environmental impact. Recently, a method for recovering neodymium as neodymium phosphate from mixed solutions was reported. This method was very useful because the main

11. Sustainable Synthetic Strategies for the Preparation of Low Molecular Weight Drugs by Biotech Routes
For billions of years, the phenomena of life and biocatalysis have been intertwined. If in the beginning biocatalysis was fundamental for the origin of life, currently it is very important for the cleaner production of pharmaceuticals and fine chemical intermediates. There is no doubt that drugs have brought great benefits to humanity, but currently, the exp
