Abstract: Here, we review the key findings on the genetic characterisation of Berenice strains of Trypanosoma cruzi isolated from a 2-year-old child, Berenice, the first patient with Chagas disease described in the literature in 1909. Be-62 and Be-78 strains were isolated from Berenice when she was 55 and 71 years Leia mais…
Resumo: A discrição acústica é crucial para a sobrevivência e eficácia operacional de submarinos. Entre os diversos tipos de ruído emitidos, o ruído hidrodinâmico relaciona-se diretamente à operação do propulsor, à forma do casco e aos seus apêndices. Este estudo propõe um método numérico para avaliar a emissão de ruído Leia mais…
Abstract: Leveraging the well-established properties of gold nanoparticle (AuNP)-DNA conjugates, this research explored a novel methodology for controlled enzymatic DNA synthesis using gold nanoparticle (AuNP)-DNA conjugates as a solid platform. To this end, Hybrid Nanoparticles (HNPs) were meticulously engineered through the functionalization of AuNPs with rationally designed DNA initiator molecules. Leia mais…
Abstract: Monitoring concrete structures is crucial for assessing the corrosion risk of steel reinforcement and optimizing maintenance strategies. This study evaluated the MnO₂/NaOH, Ag/AgCl, and Ti/MMO permanent, embeddable reference electrodes, which are rarely known or used in Brazil for corrosion monitoring. The electrodes underwent assessment tests, immersion tests in solutions Leia mais…
Abstract: This paper introduces a novel methodology for addressing the complex behavior of axial pipe-soil interaction in soft marine clays, considering drained, undrained and partially drained soil responses. The results of the proposed methodology are compared with those obtained using the traditional alpha approach for determining the axial friction factor. Leia mais…
Abstract: Monitoring is an element of landslide early warning systems. Fukuzono’s method, based on displacement and velocity monitoring, is one of the most popular methods for slope time of failure (TOF) prediction. This critical literature review aimed to systematically analyze the state-of-the-art accelerometers used for slope monitoring and TOF prediction. Leia mais…
Abstact: The bulletin “Dam Safety in the State of Sao Paulo – 2024” reports that, in the state of Sao Paulo,424 dams are registered under the National Dam Safety Policy (PNSB), as per the criteriaestablished by Federal Law No. 12,334/2010. Of these, 125 dams are used for energy generation,with 115 Leia mais…
Abstract: Compacted soil dams are critical structures for mining, water supply and power generation, particularly in tropical regions. Monitoring these dams is essential throughout their lifetime, as variations in reservoir water levels due to drought, rainfall or operational changes can significantly affect soil saturation and stability. This study developed a Leia mais…
Abstract: This work evaluated the use of corncob as a support for the immobilization of an extracellular fructosyltransferase (E.C. 2.4.1.9) from Aspergillus oryzae IPT-301, aiming at the synthesis of a stable biocatalyst for the production of fructooligosaccharides. The transfructosylation activity of the immobilized enzyme was maximized via experimental design. Additionally, Leia mais…
Abstract: Fructooligosaccharides (FOSs) are carbohydrates of high nutritional value with various prebiotic properties. Optimizing their production process is of significant interest for expanding commercial-scale production. This review discusses the properties and potential applications of FOSs, addressing production challenges and providing an economic market analysis. Bibliometric analysis of data concerning the Leia mais…
