Research ArticleOpen accessIn the abstractImpacts of the Quota System on Afro-Brazilians/Indigenous Education and Brazil's National InterestClifford Jaylen LouimeDespite Brazil's cultural diversity and the significant presence of Afro-Brazilians and indigenous people, who collectively make up 56% of the population, disparities persist in economic empowerment, political influence, and representation. In response, the Brazilian government enacted the Quota Law in 2012, reserving 50% of admissions slots in federal universities for Afro-Brazilians, indigenous people, and individuals from low-income backgrounds to enhance … …Journal of Social Sciences, Vol. 21, Issue 1 · 24 Nov 2025 · 3,404 accessesView PDFCite
Research ArticleOpen accessIn the abstractBoosting User Engagement in Ticketing System Through Gamification in IndonesiaFernandez, Willis Tan, Steven Lie, Sugiarto HartonoThe rapid growth of mobile applications in Indonesia, exemplified by the rise from 7.31 billion downloads in 2021 to 7.56 billion in 2023, poses a significant challenge in retaining user engagement post-download. This study explores how gamification can enhance user engagement in ticketing applications. Using the Self-System Model of Motivational Development (SSMMD), we investigate the influence of gamification elements achievement, … …Journal of Computer Science, Vol. 21, Issue 8 · 12 Oct 2025 · 2,459 accessesView PDFCite
Research ArticleOpen accessIn the abstractUtilization of Rumen Content by Indigenous Microorganisms in a Modified Anaerobic DigesterAlhassan Salihu Adam, Sani Yahaya, Haruna Musa et al.The current work was designed to assess the effect of modification of model digester on the kinetics that affects efficiency in biogas generation using bovine rumen content as the feedstock. A biogas plant consisting of conventional and modified fixed-dome digesters (each with 2 m3 capacity) was established; and bovine rumen content was used as feedstock. Standard methods were used to … …Energy Research Journal, Vol. 11, Issue 1 · 26 Sep 2020 · 6,784 accessesView PDFCite
Research ArticleOpen accessIn the abstractVisible Derivative Spectroscopic Monitoring of the Old Woman Creek National Estuary During a Historically Dry Year and a Wet YearLorita Nivanthi Mihindukulasooriya, Brenna Shae Mabry, Madison Slocum, Joseph Daniel OrtizVisible derivative spectroscopy was used to interpret the sediment and phytoplankton assemblages within the old woman creek natural estuarine reserve during the summers of 2016 and 2017. A Varimax-rotated Principal Component Analysis (VPCA) of reflectance data collected from four sampling sites in 2016 identified three Varimax-rotated Principal Components (VPCs): Diatom + Illite (2016-VPC 1), Dinoflagellate Algae + Cyanobacteria + Cryptophytes … …American Journal of Environmental Sciences, Vol. 19, Issue 6 · 11 Jul 2024 · 4,672 accessesView PDFCite
Case ReportOpen accessIn the abstractHistopathology of Microbially Induced Corrosion and Cluster Failure of Moderately Rough Surface Oral Implants in a Resident Bone MicrobiotaStephen Nelson, Helen Hu et al.This case report presents as a maxillary "cluster-failure", where six moderately rough-surface oral implants (1-2 microns) were installed to support a full-arch hybrid bridge. Understanding cluster failures requires the acknowledgment of biofilm science that recognizes the persistence of bacterial infection in bone following extraction and the need to bioremediate the bone-bed, by surgical debridement, before implant installation. The patient, a … …Current Research in Dentistry, Vol. 15, Issue 1 · 28 Feb 2024 · 8,486 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Deproteinization, Antioxidant Acticities and Inhibitory Effect on α-Amylase of Polysaccharides from Corn SilkYaping Li, Songbiao Shi, Xiudong Yang, Hongli ZhouAn approach of deproteinization of polysaccharides from corn silk (CSPs) was established to improve the purity and activities of CSPs by investigating Sevag method, trichloroacetic acid (TCA) method and HCl method. Deproteinization rate, polysaccharide retention rate, antioxidant activities and inhibition α-amylase effects were used as indicative mark to select suitable deproteinization method of CSPs. The crude CSPs was extracted by … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 2 · 23 May 2019 · 9,299 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Indoor CO2 Concentration Using Split Ventilation Systems as an Indicator of COVID-19 TransmissionManuel Batista, Oscar Bulgim, Ericka Matus et al.We measured the indoor CO2 concentration in occupied areas with ventilation systems that recirculate air without an external air supply. The average time required to achieve the highest probability of contagion was also measured based on the number of participants in the group. Three different experimental groups were evaluated: Group One (G1), which included 5 participants; Group Two (G2), with … …American Journal of Applied Sciences, Vol. 20, Issue 1 · 23 Aug 2023 · 6,057 accessesView PDFCite
Review ArticleOpen accessIn the abstractPreparation and Functional Evaluation of Compound Bletilla striata EssenceMengnan Zhu, Jiameng Shen, Hongju Zhang et al.The purpose of this study was to prepare a multi-functional skin care product and apply more plant resources to the skin care industry. The crude polysaccharides from Bletilla striata, Panax ginseng, and Tremella fuciformis were extracted under different conditions based on the characteristics of the plants. The formula ratio of the compound Bletilla striata essence was optimized through an orthogonal … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 1 · 8 Jan 2023 · 5,911 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Prescriptive Specialized Learning Management System for Academic Feedback towards Improved LearningAnnette van der Merwe, Tiny du Toit, Hennie KrugerThe dynamic nature of technological advances is causing changes in many fields and especially in tertiary education. Student numbers are increasing annually and institutions need to maintain education quality whilst ensuring student retention. A specialized learning management system (SLMS) was developed in this study that provides students with comprehensive feedback which will enable them to better manage their academic performance. … …Journal of Computer Science, Vol. 14, Issue 10 · 24 Oct 2018 · 7,487 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign and Analysis of SRAM Cell for Smart ApplicationPushkar Praveen, Rakesh Kumar SinghIn today's circuittechnology, power consumption and savings are key concerns. The driving reasonsbehind these innovations are portable devices that require high throughput andlow power dissipation, such as computers, phones, and Personal DigitalAssistants (PDAs). In portable devices, reducing or decreasing IC dissipatedpower through design optimization is a big problem, and restricted batterylifespan places very severe restrictions on overall power usage.
