Research ArticleOpen accessIn the abstractComparative Studies of the Determination of Divalent Cadmium, Lead and Copper in the Boiling Medicinal Herbs by Stripping Voltammetry and by Atomic Absorption SpectrometryAhmed Hassan, Jamal A. MayoufCadmium, lead and copper were determined in ten Libyian boiling medicinal herbs samples by differential pulse anodic stripping voltammetry as well as by atomic absorption spectrometry. Voltammetric method was done at Hanging Mercury Dropping Electrode (HMDE) in Briton-Robinson buffer solution of pH ~2.1 at 25± 0.1°C. The sample preparation was carried out by boiling 2.0g of a finely pulverized plant … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,033 accessesView PDFCite
Research ArticleOpen accessIn the abstractUptake and Recovery of Lead by Agarose Gel PolymersAnurag Pandey, Anupam Shukla, Lalitagauri RayProblem statement: The uptake and recovery of lead ions were investigated by using agarose gel polymers. Approach: The experimental results showed that the agarose gel were effective in removing Pb (II) from solution. Biosorption equilibrium was approached within 4 h. Pseudo second-order was applicable to all the sorption data over the entire time range. Results: The sorption data conformed well … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 7,632 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Pulverised Fly Ash (PFA) as an Ameliorant of Lead Contaminated SoilsEdmond Gatima, Mwinyikione Mwinyihija, Ken KillhamFly Ash (FA) is obtained by electrostatic or mechanical precipitation of dust-like particles from the flue gases of furnace fired with coal or lignite at 1100 to 1400°C. About 95-99% of Fly Ash consists of oxides of Si, Al, Fe and Ca, about 0.5 to 3.5% consists of Na, P, K and S and the remainder is composed of trace … …American Journal of Environmental Sciences, Vol. 1, Issue 3 · 30 Sep 2005 · 7,017 accessesView PDFCite
Research ArticleOpen accessIn the abstractOn the Stability of a Certain Class of Linear Time-Varying SystemsM. De la SenThis study firstly considers the exponential stability of unforced linear systems of slowly time-varying dynamics. Possible switchings of the system structure to unstable dynamics during certain finite time intervals are admitted. The maintenance of global exponential stability does not necessarily require at most a finite number of switchings in the dynamics while infinitely many switches can also lead to stability. … …American Journal of Applied Sciences, Vol. 2, Issue 8 · 31 Aug 2005 · 6,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Development of a New, Rapid, Amperometric Immunosensor for the Detection of Low Concentrations of Bacteria Part II: Optimization of the System for Escherichia coliEric Carnes, Ebtisam WilkinsThe optimization of a flow-through immunoassay system was conducted to achieve rapid detection of low concentrations of E. coli bacteria. The system includes a new immunosensor that uses newly developed, disposable immunofiltration membranes to yield a system that is sensitive as well as simple. Comparison of the performance of this system with conventional immunoassays demonstrated a significantly shorter time for … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 6,783 accessesView PDFCite
Research ArticleOpen accessIn the abstractTransformative Effects of Big Data on Advanced Data Analytics: Open Issues and Critical ChallengesShabnam Kumari, P. MuthulakshmiWe are living in the period of the information era (i.e., where data/information is the new oil for companies/industries). The term big data had been authored to depict this age. This study characterizes a lot on the idea of big data and its progress over the previous decade to till date. This study presents the meaning of this new idea … …Journal of Computer Science, Vol. 18, Issue 6 · 14 Jun 2022 · 6,354 accessesView PDFCite
Literature ReviewOpen accessIn the abstractLiterature Study on Factors Influencing the Biochemical Analytes Stability in Blood, Serum and Plasma: Systematic ReviewSamia El Mahi, Asmae Tantane, Sanaa Ait Hamou, Said OubraimBlood testing represents an essential phase in diagnosis and treatment. It is important to comprehend the biochemical analytes' stability. This research gathers information from different journals that have investigated the stability of biochemical analytes under different conditions. This research aims to collect and analyze data about conditions that promote stability, conditions that lead to instability, and how stability varies in … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 3 · 21 Aug 2024 · 5,198 accessesView PDFCite
Review ArticleOpen accessIn the abstractAdditive Manufacturing in the Aerospace IndustryLidong Wang, Reed Mosher, Patti DuettThe main advantages of Additive Manufacturing (AM) of metals in the aerospace industry are part consolidation; the reduction of lead time, the construction of complicated structures easily with a great Strength-to-Weight (S:W) ratio; production of parts on-demand with reduced inventory, uncertainty and the costs of supply chains. Ti6Al4V and nickel-based alloys are commonly used AM materials for aerospace parts. Ground-based … …American Journal of Engineering and Applied Sciences, Vol. 17, Issue 3 · 12 Jun 2024 · 8,116 accessesView PDFCite

Case ReportOpen accessIn the abstractBeyond Occam’s Razor: Diffuse Large B-Cell Lymphoma With Concurrent Acid-Fast Bacilli Positivity–A Case ReportOm Sharma, Shaurya Gupta, Prasan Kumar PandaIn tuberculosis-endemic regions, necrotizing lymphadenitis with Acid-Fast Bacilli (AFB) is often presumed to indicate tuberculous etiology, but this assumption may lead to misdiagnosis when immunophenotypic evaluation is not performed. In this report, we present the case of an immunocompetent elderly man who presented with prolonged high-grade fever, progressive abdominal distension, and stable cervical and submandibular lymphadenopathy. He had been empirically … …American Journal of Infectious Diseases, Vol. 22, Issue 1 · 24 Jul 2026 · 1,239 accessesView PDFCite
