Research ArticleOpen accessIn the keywordsHomogeneous Bubbles during Jet Impingement QuenchingM. A. Islam, S. F. AhmedProblem statement: Jet impingement quenching has a very effective and large cooling potential and is a very effective means of cooling for many applications. It gives rise to heterogeneous and/or homogeneous nucleation of bubbles, which is yet to be explored. Approach: Analytically investigate the phenomenon that happened during a brief contact of a water jet impinging on a hot surface. … …American Journal of Applied Sciences, Vol. 7, Issue 6 · 30 Jun 2010 · 7,162 accessesView PDFCite
Research ArticleOpen accessIn the keywordsLandslide Susceptibility Assessment using Frequency Ratio Model Applied to an Area along the E-W Highway (Gerik-Jeli)Tareq H. Mezughi, Juhari Mat Akhir, Abdul Ghani Rafek, Ibrahim AbdullahProblem statement: The study area is frequently subjected to landslides especially alongside the E-W high way. This study demonstrates the implementation of the Frequency Ratio (FR) model with the aid of GIS tool to assess the contribution of every predisposing factor on landslides and produce a landslide susceptibility map to the area. Approach: A landslide location map of the study … …American Journal of Environmental Sciences, Vol. 7, Issue 1 · 28 Feb 2011 · 9,093 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Monitoring of Endocrine-Disrupting Chemicals: Analytical Chemistry and Biological Assessment ApproachesChangjin Li, Jing Huo, Zijun Dou et al.Endocrine-Disrupting Chemicals (EDCs) in aquatic environments pose significant threats to ecosystems and human health. These compounds interfere with hormonal regulation at low concentrations and have non-monotonic dose-response relationships, posing challenges to conventional risk assessment. This review systematically compares current EDC monitoring methods, including instrumental chemical analysis and receptor-based biological detection systems, to evaluate sensitivity thresholds, sample throughput, and mechanistic selectivity … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 2 · 3 Jul 2026 · 1,081 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Hydrodistillation Extraction by Response Surface Methodology and Evaluation of the Antioxidant and Antimicrobial Activities of Essential Oils from Phragmites communis (Cav) TrinXin-Tong Zou, Hong-Yuan Ma, Yu-He Li et al.The principal objectives of this study encompass three distinct aspects: firstly, to streamline the extraction process of Phragmites communis (Cav) Trin essential oil; secondly, to systematically analyze the essential oil’s chemical composition; and finally, to evaluate biological activity. Through the system optimization experiment, the optimal extraction process was determined: the crushing size was set to 10 mesh, the total solid-liquid … …American Journal of Biochemistry and Biotechnology, Vol. 21, Issue 3 · 6 Jan 2026 · 2,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractNovel LC-MS/MS Method for CJ-023423 (Grapiprant) Determination in Rabbit PlasmaElena Baralla, Virginia De Vito, Maria Vittoria Varoni et al.Grapiprant is a new anti-inflammatory drug that preferentially targets the EP4 receptor of prostaglandin E2 limiting the wide range of adverse effects caused by the classical non steroideal anti-inflammatory drugs. The aim of this study was to develop and validate a new, simple, sensitive and rapid Liquid Chromatography tandem Mass Spectrometry method (LC-MS/MS) in order to quantify this novel drug … …American Journal of Animal and Veterinary Sciences, Vol. 13, Issue 2 · 24 May 2018 · 7,988 accessesView PDFCite
Research ArticleOpen accessIn the abstractDirect Analysis of Six Pharmaceuticals using Online Solid Phase Extraction Liquid ChromatographySiti Norbayu Mohd Subari, Rozita Osman, Norashikin SaimIn this study, three parameters (sample volume, cleanup and elution step) in large volume injection online Solid Phase Extraction Liquid Chromatography with diode array detection (SPE-LC) were optimized for the determination of six pharmaceuticals in wastewater samples. Preconcentration and separation were carried out using 2 columns, Dionex Ion Pac AG14A and Acclaim Polar Advantage II. Response Surface Methodology (RSM) was … …American Journal of Applied Sciences, Vol. 14, Issue 5 · 31 Mar 2017 · 7,513 accessesView PDFCite
Research ArticleOpen accessIn the abstractDetermination of Abscisic Acid and its Relationship to Drought Stress Based on Cowpea Varieties with Different Capability of Drought ResistanceWei Lei, Shian Huang, Shaohu Tang et al.Cowpea (Vigna unguiculata L.) is one of the most important grain legume supplying necessarily dietary proteins. Although its can tolerate drought environment, still the severe condition can limit the growth and development of this plant. Abscisic acid (ABA) has a crucial function in stress physiology, but little information is available for methods describing ABA determination in cowpea and its relationship … …American Journal of Biochemistry and Biotechnology, Vol. 12, Issue 1 · 30 Mar 2016 · 8,458 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Nickel and Zinc by Residual SoilsNur ’Aishah Zarime, W. Y. Wan Zuhairi, Sivarama KrishnaSoil has long been utilized as low cost liner material to prevent contamination from leachate to groundwater media. To find a suitable soil material for this purpose is a great challenge. This study describes the potential use of residual soil to functions as engineered clay liner for waste disposal landfill in Malaysia. Three types of residual soils were investigated namely … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 5 Dec 2014 · 7,116 accessesView PDFCite
Research ArticleOpen accessIn the abstractCOLORIMETRIC DETERMINATION OF CEFQUINOME SULPHATE IN BULK AND DOSAGE FORM USING AMMONIUM MOLYBDATEShaza Wageialla Shantier, Elrasheed Ahmed GadkariemThis study was designed to develop two colorimetric methods for the determination of Cefquinome Sulphate (CS) in bulk and dosage forms using two different concentrations of molybdenum solution. The developed methods were based on the oxidation of CS with 2% ammonium molybdate, in the presence of sulphuric acid, producing a green colored product with λmax at 409 nm (Method I) … …American Journal of Applied Sciences, Vol. 11, Issue 2 · 20 Dec 2013 · 7,051 accessesView PDFCite
