Research ArticleOpen accessIn the abstractA New Hybrid Model to Predict the Performance of Trainee Teachers Based on Clustering and ClassificationYissam Lakhdar, Khawla EL-Bendadi, Brahim BakkasThis article explores how artificial intelligence, particularly machine learning, can be used to assess and predict the performance of trainee teachers in Morocco. Considering the country's focus on integrating technology into education and the challenges posed by the COVID-19 pandemic, the authors propose a novel hybrid model that combines clustering and classification algorithms. This model aims to understand the Information … …Journal of Computer Science, Vol. 20, Issue 9 · 26 Jun 2024 · 5,100 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 · 8,482 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultilevel Mixed Analysis and Mapping on Divorce Problem in UAEFaisal G. KhamisDespite the wealth of research investigating the divorce problem in the developed countries, few and inconsistent studies investigated this problem at emirate-level in developing countries, such as United Arab Emirates (UAE). The Questions are raised whether divorce is changed over time and whether clustering in divorce exists within emirates in UAE. The objectives are to investigate the change in divorce … …Journal of Mathematics and Statistics, Vol. 12, Issue 4 · 31 Oct 2016 · 7,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractLong-Term Changes in Mangrove Landscape of the Niger River Delta, NigeriaPing Wang, Aroloye O. Numbere, Gerardo R. CamiloThe Niger Delta mangrove is the third largest in the world and the largest in Africa. Since the 1960s oil and gas exploration has become an important economic activity, resulting in significant alteration of the landscape via pollution, urbanization and invasion. Landsat images of six different years (1984, 1986, 2000, 2003, 2005 and 2007) were used to determine land cover … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 18 Jun 2016 · 8,839 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Association between Total Mixed Ration Particle Size and Fecal Scores in Holstein Lactating Dairy Cows from Florida, USAPedro Melendez, Elizabeth RoyThe objective of this study was to determine the association between the proportion of particles greater than 19 mm in a total mixed ration fed to dairy cattle and their fecal score. Over a 22 day period, random feed samples were collected twice a day from a one-side barn and assessed for particle size using the Pennsylvania State Particle Separator. … …American Journal of Animal and Veterinary Sciences, Vol. 11, Issue 1 · 6 Jan 2016 · 8,084 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination and Source Apportionment of Selected Heavy Metals in Aerosol Samples Collected from SebeleAlfred Sello Likuku, Gilbert Kabelo Gaboutloeloe, Khumoetsile B. MmolawaBush fires and dust in the dry winter months establish moderately high background levels of aerosols. Emissions into the atmosphere by copper mines, coal mines and vehicular emissions are all possible sources of air pollution with heavy metals. Although there has been assessment and monitoring of heavy metals and their air pollution in other countries such as Brazil, Europe and … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 25 Apr 2013 · 7,441 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Analysis of Operationalization and Acceptability of Business to Business Transaction: A mixed Method ApproachYusuf Muhammad-Bashir Owolabi, Ahamed Kameel Mydin Meera, Gairuzazmi Mat Ghani et al.Business to business barter exchange is a form of transaction that is gaining popularity during the economic downtown despite the fact that money exchange supersede the traditional barter exchange due to a number of inherent problems it has. This study explores the operation and user’s acceptance of business to business barter exchange in Malaysia that has made barter exchange feasible … …American Journal of Applied Sciences, Vol. 9, Issue 9 · 30 Jul 2012 · 7,727 accessesView PDFCite
