With the increasing number of protein sequencing data, the first step in identifying this macromolecule is to compare proteins to identify their similarities with known proteins. This similarity analysis can identify evolutionary relationships between the compared spe cies. Similar sequences imply species that share a recent common ancestor. However, the sequences are not always conserved in evolution, so in this case, a comparison with the more conserved structure can be an alternative t...

In recent years, bacterial cellulose (BC) has been the object of much research due to its high potential for application in areas such as biomedicine or materials, as well as because its biosynthesis is environmentally friendly. The BC is characterized as a homopolymer and is differentiated from vegetable cellulose by its properties, highlighting mainly the biocompatibility and biodegradability of the materials produced. The production of BC composites with various polymers is an effe...

The use of renewable energy sources is a big step for the future of a nation, especially Brazil has been highlighted by the large availability of solar energy throughout its territory. However, the presence of clouds and aerosols in the atmosphere can compromise the use of this type of energy in the electrical system, predicting associated meteorological variables a challenging task. In this sense, in view of a sustainable model of energy generation and recent advances in the area o...

Arising from the combination of tailored chemical composition and thermomechanical processing, advanced high strength steels (AHSS) provide an important balance between mechanical strength and weight reduction desired in automobiles. In this context, 22MnB5 steel stands out for offering mechanical strength levels around 1500 MPa in the hot-stamped condition, after quenching. Joining of components in the automotive industry, usually achieved by the resistance spot welding (RSW) proce...

Super duplex stainless steels (SDSS) are steels with a high content of alloying elements. These steels were introduced in the oil and gas industry due to their high resistance to pitting corrosion. These steels are currently used in a wide range of applications due to their excellent corrosion resistance combined with high mechanical strength. They are often selected for applications in chloride-containing environments, such as seawater, where stress and pitting corrosion can occur....

The largest installed capacity for power generation in Brazil comes from hydroelectric plants. However, the scenario of water scarcity with population and economic growth has become a challenge for Brazilian authorities. After the energy crisis of 2001, the country developed public policies with the objective of encouraging the expansion of other renewable sources of electricity. As a highlight, wind energy added 17.747 MW of installed capacity to the National Interconnected System ...

In a context of high competitiveness and digital transformation, technological advances with the potential to increase the efficiency of industrial units are causing an exponential increase in the use of new technologies in these environments. Wireless communication is one of the most implemented solutions, allowing a high level of interconnectivity in different systems, including critical systems responsible for production control and safety. The performance gain with the increase in wireles...

The development of products and technologies (DP&T) is a process that involves several activities and a technical team, usually interdisciplinary, requiring considerable execution time and significant investments for the project to be effective. There are several methods, tools and procedures that intertwine throughout the development cycle. Currently, some DP&T methodologies are well established and are widely used by companies and technology centers. Additionally, in recent years,...
