Research ArticleOpen accessIn the author namesOn a Novel Closed-Form Analytical Solution for Unsteady Solidification: Theory and ApplicationGueber Elias Mendes Santos Júnior, Fernando S. Rocha, Ana Beatriz S. Silva et al.Numerical modeling of transient solidification under convective boundary conditions presents a significant challenge because accurately tracking the solid–liquid interface is essential for obtaining a stable solution. Although analytical solutions are generally straightforward to apply, the growing demand for energy storage driven by mismatches between supply and demand in renewable‑energy systems requires reliable predictive tools for Latent Heat Thermal Energy Storage … …American Journal of Engineering and Applied Sciences, Vol. 19, Issue 1 · 21 May 2026 · 1,680 accessesView PDFCite
Review ArticleOpen accessIn the author namesA Systematic Review on Wake-up Radios Applied to Wireless Sensor NetworksMarco Aurélio Spohn, Caetano Mazzoni Ranieri, Agnelo Rocha da Silva, Jó UeyamaWireless Sensor Networks (WSNs) are the backbone of many monitoring applications, especially in the Internet of Things (IoT) context. However, efficient power management becomes a critical challenge when sensor nodes rely on disposable batteries. The deployment of WSNs must ensure coverage and connectivity, but the resulting distribution of nodes and underlying protocols directly impact the network’s lifetime. The concept of … …Journal of Computer Science, Vol. 21, Issue 3 · 4 Feb 2025 · 6,212 accessesView PDFCite
Research ArticleOpen accessIn the author namesHepato and Nephrotoxicity Caused by Sub-Chronic Exposure to Relevant Concentrations of Human Exposure to Glyphosate-Based Herbicide: An Experimental Study in RatsFernanda de Maria Serra, Letícia Rocha Magalhães, Beatriz Bertholace Magalhães Silva et al.Glyphosate's remarkable effectiveness in weed control has made it among the foremost widely employed herbicides globally. Several Glyphosate-Based Herbicides (GBHs) contain 1-4 dioxane, a compound known to induce cancer in animals and potentially contribute to liver and kidney damage in humans. The objective was to assess the liver and kidney toxicity resulting from sub-chronic exposure to GBH in rats. Eighty … …OnLine Journal of Biological Sciences, Vol. 24, Issue 2 · 26 Dec 2023 · 5,198 accessesView PDFCite
Research ArticleOpen accessIn the author namesCanonical Correlation-based Tests for the Agreement of Sensory PanelistsMarcela C Rocha, Eric B Ferreira, Daniel F FerreiraThe reliability of the results of sensory analysis is directly linked to the performance of panel of assessors what, in general, means the ability of judges to identify small differences between products, the replicability of their ratings for the same product and the panel consonance. The panel consonance - usually called unidimensionality - can be understood as the agreement between … …Journal of Mathematics and Statistics, Vol. 16, Issue 1 · 11 Jan 2020 · 7,054 accessesView PDFCite
Research ArticleOpen accessIn the author namesEvaluation of the use of Polyurethane Residue Aggregated to the Plaster of Civil ConstructionGuilherme Moraes de Oliveira, Vittória Caroline Souza dos Santos, José de Souza, Tatiana Louise Ávila C. RochaThe study deals with the reuse of Polyurethane (PU) obtained from a kitchen sponge added to plaster for use in civil engineering. The kitchen sponge is an item widely used by the population in their daily lives, generating a significant accumulation of waste. Thus, from the analysis of the properties of the kitchen sponge, it was seeking possible reuse of … …American Journal of Engineering and Applied Sciences, Vol. 12, Issue 4 · 27 Nov 2019 · 7,147 accessesView PDFCite

Research ArticleOpen accessIn the author namesEvaluation of Different Oral Rehydration Solutions for Diarrheic Dairy CalvesEvangelina Miqueo, Jackeline Thais da Silva, Fernanda Lavínia Moura Silva et al.Regardless of the causative agent, diarrhea results in large loss of water and electrolytes, which leads to reduced performance and mortality. The aim of this study was to evaluate oral rehydration solutions in order to determine the most effective in restoring electrolytes and water while maintaining animal performance. Forty two calves (14 per treatment) were distributed in one of three … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 4 · 26 Nov 2018 · 8,387 accessesView PDFCite
Research ArticleOpen accessIn the author namesIncrease in Crude Protein Content of Milk Replacers with Vegetable Protein: Effect on Health and Dairy Calves' PerformanceEvangelina Miqueo, Thais Manzoni Torrezan, Nathalia Britto Rocha et al.The use of milk replacer instead of whole milk may be an economical alternative to calf-rearing systems. However, together with the volume fed, its composition is critical for high performance, especially regarding the origin of the protein. Two milk replacers with different protein content were evaluated to see the effect on the performance of calves. Thirty-three Holstein calves were distributed … …American Journal of Animal and Veterinary Sciences, Vol. 12, Issue 1 · 6 Feb 2017 · 7,779 accessesView PDFCite
