    Phyton-International Journal of Experimental Botany, Vol.94, No.9, pp. 2797-2814, 2025, DOI:10.32604/phyton.2025.068089 - 30 September 2025

    Abstract Due to its tolerance to water deficit and salinity, sorghum is considered a suitable crop for cultivation in regions affected by these stress conditions, enabling the efficient use of limited water resources. This study evaluated the resilience of the sweet sorghum cultivar BRS 506 under water deficit and salinity stress, focusing on water relations and yield performance in semiarid conditions. A randomized complete block design was employed in a 3 × 3 factorial arrangement with four replicates. Treatments consisted of three levels of irrigation water salinity (1.50, 3.75, and 6.00 dS m−1) and three irrigation levels… More >

    Luiz Felipe Souza Fonseca1, Heitor do Nascimento Andrade1, João Marcelo Fernandes Gualberto de Galiza2, Raphael Abrahão1, Hamid Boleydei3, Silvia Guillén-Lambea4, Monica Carvalho1,*

    Energy Engineering, Vol.122, No.8, pp. 3265-3283, 2025, DOI:10.32604/ee.2025.066218 - 24 July 2025

    Abstract The application of different coatings on solar photovoltaic (PV) panels can be an efficient solution to increase performance and further mitigate the emission of greenhouse gases. This study uses the Life Cycle Assessment (LCA) methodology and the environmental payback concept to analyze the effects of the application of a nano-silica coating on a solar PV system installed in the Brazilian Northeast. Firstly, an uncoated reference 16.4 MW PV system is designed, and the detailed inventory is presented (PV panels, supporting structure, inverters, junction boxes, cables, transportation, maintenance and operation—including the replacement of equipment). The results… More > Graphic Abstract

    Techno-Economic Comparison of Electrochemical Batteries and Supercapacitors for Solar Energy Storage in a Brazil Island Application: Off-Grid and On-Grid Configurations

    Alex Ximenes Naves1, Gladys Maquera2, Assed Haddad1, Dieter Boer3,*

    Energy Engineering, Vol.122, No.7, pp. 2611-2636, 2025, DOI:10.32604/ee.2025.061971 - 27 June 2025

    Abstract The growing concern for energy efficiency and the increasing deployment of intermittent renewable energies has led to the development of technologies for capturing, storing, and discharging energy. Supercapacitors can be considered where batteries do not meet the requirements. However, supercapacitors in systems with a slower charge/discharge cycle, such as photovoltaic systems (PVS), present other obstacles that make replacing batteries more challenging. An extensive literature review unveils a knowledge gap regarding a methodological comparison of batteries and supercapacitors. In this study, we address the technological feasibility of intermittent renewable energy generation systems, focusing on storage solutions… More > Graphic Abstract

    Oncology Research, Vol.32, No.10, pp. 1565-1573, 2024, DOI:10.32604/or.2024.052179 - 18 September 2024

    Abstract Objectives: The Brazilian Unified Health System (Sistema Único de Saúde−SUS) is the universal public healthcare system of Brazil that maintains a nationwide database of its patients. Our primary objective was to analyze regional and temporal trends, while our secondary goal was to establish correlations between states’ health economy status and their prostate cancer (PCa) epidemiology. Methods: We analyzed Brazil’s nationwide data on prostate cancer (PCa) incidence, mortality, and care gathered between 2013 and 2021 by the Information Technology Department of SUS (DATA-SUS), updated monthly using the International Classification of Diseases (ICD-10) code. Results: In the period,… More >

    Gustavo Foronda1,2, Vanessa Ferreira Amorim de Melo2,3,*, Claudia Regina Pinheiro de Castro Grau4, Ingrid Magatti Piva1, Glaucia Maria Penha Tavares4, Ana Cristina Sayuri Tanaka1, Nana Miura1

    Congenital Heart Disease, Vol.18, No.6, pp. 649-656, 2023, DOI:10.32604/chd.2023.027987 - 19 January 2024

    Abstract Background: Children with congenital heart disease (CHD), even after surgical approaches, and especially those who undergo staged procedures in the first months of life, remain vulnerable to readmissions and complications, requiring very close monitoring and differentiated intervention strategies. Methods: Descriptive and exploratory study, of the experience report type, which presents the process of building the high-risk outpatient clinic for complex congenital heart diseases (AAR) at the Instituto do Coração (InCor). Results: Report of the path taken to structure the AAR, demonstrating the organization, interface with the multidisciplinary team, admission and discharge criteria, training, and patient profile.… More >

    Digital Social and Emotional Literacy Intervention for Vulnerable Children in Brazil: Participants’ Experiences

    Louise Freeland1, Michelle O’Reilly2, Juliana Fleury3, Sarah Adams4, Panos Vostanis1,*

    International Journal of Mental Health Promotion, Vol.24, No.1, pp. 51-67, 2022, DOI:10.32604/ijmhp.2022.015706 - 20 December 2021

    Abstract Social emotional literacy (SEL) interventions are widely implemented through schools, with growing evidence for a range of positive child outcomes. Increasingly, such interventions are delivered on online platforms. To date, there is limited evidence about digital SEL interventions in low- and middle-income countries (LMIC). The aim of this study was to explore the perceptions and experiences of children, parents and facilitator of the potential value of addressing SEL via tailored digital intervention. The intervention was designed to help children, in Brazil, to cope during the first COVID-19 pandemic lockdown. The intervention was delivered via a… More >

    Qualitative Comparison between the Brazilian Labeling Program for Buildings and the Portuguese Energy Certification System for Buildings: Proposals for Improving Brazilian Regulations

    Jaime Francisco de Sousa Resende1,*, Andrea Lucia Teixeira Charbel2, Teresa Cristina Bessa Nogueira Assunção3

    Energy Engineering, Vol.118, No.3, pp. 615-629, 2021, DOI:10.32604/EE.2021.014588 - 22 March 2021

    Abstract Buildings represent a significant share of the world’s energy consumption, and the sector has drawn the attention of governments, which have adopted policies to reduce energy expenditure. The Certifications of Energy Efficiency in Buildings stand out as one possible solution to achieve this goal, employed in several countries worldwide. The European Union presents advanced energy assessment programs for buildings, being a reference and model for several other regulations in the world. The Energy Certification System for Buildings (SCE) of Portugal is considered a success case, reflected in the significant number of energy certificates issued. The… More >

    CMES-Computer Modeling in Engineering & Sciences, Vol.125, No.3, pp. 991-1031, 2020, DOI:10.32604/cmes.2020.012503 - 15 December 2020

    Abstract We have proposed a new mathematical method, the SEIHCRD model, which has an excellent potential to predict the incidence of COVID-19 diseases. Our proposed SEIHCRD model is an extension of the SEIR model. Three-compartments have added death, hospitalized, and critical, which improves the basic understanding of disease spread and results. We have studied COVID-19 cases of six countries, where the impact of this disease in the highest are Brazil, India, Italy, Spain, the United Kingdom, and the United States. After estimating model parameters based on available clinical data, the model will propagate and forecast dynamic… More >

    Morphological Characterization of Brazil Nut Tree (Bertholletia excelsa) Fruit Pericarp

    Gustavo P. Petrechen1,4,*, Marcos Arduin3, José D. Ambrósio1,2

    Journal of Renewable Materials, Vol.7, No.7, pp. 683-692, 2019, DOI:10.32604/jrm.2019.04588

    Abstract This article presents the overall morphological structure of the Brazil nut tree (Bertholletia excelsa) fruit pericarp, from macro to nano scale. The acquired knowledge would be used for the development of new applications, like using the materials as fillers for biocomposites, or as a hierarchical architecture model for biomimetics. This research was performed using stereo and light microscopy and conventional and force field emission scanning electron microscopy. The pericarp presents three layers: the exocarp, a dark gray, brittle and fragile outer layer; the mesocarp, a beige, dry, rigid, impermeable and fibrous intermediate layer; and the… More >
