Research ArticleOpen accessEvery word in the titleThermodynamic Profile of Some Heavy Metal Ions Adsorption Onto Biomaterial SurfacesMedhat A. ShakerThe adsorption of Co2+, Zn2+, Pb2+ and Hg2+ onto dried non-living biomass (NB) of different Pseudomonas strains has been investigated in detail. Maximum adsorption of these cations is achieved at optimum pH values from 3.5 to 4.5 to avoid hydrolysis, polymerization and precipitation of metal cations in the treatment solutions. The experimental data obtained at different temperatures were fitted to … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 6,877 accessesView PDFCite
Research ArticleOpen accessIn the keywordsSequence Stratigraphic Analysis from Well Logs of an X-Field, Niger Delta, NigeriaGodwin Omokenu Emujakporue, Alphonsus Joseph EyoThe sequence stratigraphic analysis of the area was studied using well log information in order to determine the lithostratigraphy, chronostratigraphy, possible reservoir sands, age and depositional environment of the study area for opportunities that will support exploration program. The depositional environment penetrated by the wells interpreted from log signatures gave three major facies association. The blocky and coarsening upward (funnel … …Current Research in Geoscience, Vol. 6, Issue 2 · 11 Jul 2016 · 13,975 accessesView PDFCite
Research ArticleOpen accessIn the keywordsForm to FabricationHenning Duerr, Sagar Vanapalli, Christian Pfuetze et al.A creative idea is always constrained with lot of factors such as aesthetics, material, fabrication, tools etc. With the introduction of the digital and robotic fabrication, some constrains can be denied and at the same time some new constrains are added. In this study, we discuss how to prototype a creative idea with different fabrication approaches in the framework of … …International Journal of Structural Glass and Advanced Materials Research, Vol. 4, Issue 1 · 23 Mar 2020 · 6,860 accessesView PDFCite
Literature ReviewOpen accessIn the keywordsOn Destructive Peri-implant Bone LossAndre J. ViljoenDestructive peri-implant bone loss is distressing for both the patient and the treating dentist(s). In severe cases peri-implant bone loss may cause jawbone mutilation, making re-treatment highly complex or impossible and violating the treatment philosophy of “first, do no harm”. There are a multitude of causes of bone loss around a dental implant. These include, but are not limited to, … …Current Research in Dentistry, Vol. 10, Issue 1 · 25 Nov 2019 · 7,472 accessesView PDFCite
Research ArticleOpen accessIn the keywordsComparison of Stochastic and Deterministic Methods for Mapping Environmental Noise from Opencast QuarriesDario Lippiello, Guido Alfaro Degan, Mario PinzariAn accurate mapping of the acoustic spatial variability generated by quarrying plants constitutes an important step in the assessment of the environmental compatibility of the extraction site with the surrounding area. This paper refers to the results of a study comparing performances obtained by stochastic and deterministic methods to determine the acoustic climate of the areas surrounding opencast quarries. To … …American Journal of Environmental Sciences, Vol. 12, Issue 2 · 28 Mar 2016 · 7,394 accessesView PDFCite
Research ArticleOpen accessIn the keywordsDeposition and Characterization of CdS Nano Thin Film with Complexing Agent TriethanolamineK. Manikandan, C. Surendra Dilip, P. Mani, J. Joseph PrinceThe equimolar concentration thin films of Cadmium Sulfide (CdxSx) with the complexing agent TEA were deposited on a glass substrate by the SILAR technique. The crystalline nature with face centered cubic crystal system of the CdS films is determined from X-ray diffraction analysis. The broadened diffraction peaks indicated nano sized particles of the film materials. The surface morphology of the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 1 Jun 2015 · 8,419 accessesView PDFCite
Research ArticleOpen accessIn the keywordsExact Solutions of Mass Transfer over a Stretching Surface with Chemical Reaction and Suction/InjectionHassan A.M. El-ArabawyProblem statement: In this research the researchers studied and made an analysis to the effects of suction/injection and chemical reaction on mass transfer characteristics over a stretching surface. The researcher studied the effects of some parameters appear on mass transfer. Approach: Transforming the system of partial differential equations to a system of ordinary differential equations and obtaining the exact analytical … …Journal of Mathematics and Statistics, Vol. 5, Issue 3 · 30 Sep 2009 · 7,510 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
Literature ReviewOpen accessIn the abstractOptimizing the Surface-Active Performances of Cat-Anionic Mixtures: A Short ReviewCamillo A. La MesaMixtures of oppositely charged surfactants are used for applications requiring extensive foaming. This holds true for cat-anionic systems. Their bulk behavior is known in detail, when surface, or interface, properties do not attract the same attention. The thermodynamic features of such systems and the strategies interrelating the behavior in bulk to that at surfaces are outlined. Such systems are strongly … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 4 · 4 Nov 2023 · 4,931 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomated Terrain Classification with a Bayesian Hyperparameter Optimized Deep Supervised Autoencoder ModelTiny Du Toit, Hennie Kruger, Annette Van Der MerweTerrain classification according to specific terrain attributes, has become increasingly important in certain decision-making scenarios. Automated robots are often utilized to traverse a specific surface to collect data that can be used in classification models to identify a specific terrain. In this study, a supervised autoencoder model (i.e., an autoencoder combined with a supervised learner such as a multilayer perceptron) … …Journal of Computer Science, Vol. 19, Issue 9 · 31 Aug 2023 · 5,019 accessesView PDFCite
