Research ArticleOpen accessPhrase in the titleFabrication of X-Ray Optics for a Portable Total Reflection X-Ray Fluorescence Spectrometer Using Electrolytic in Process Dressing Grinding and Magnetorheological FinishingShinsuke Kunimura, Hiroshi Kasuga, Yosuke Hachisu, Hitoshi OhmoriProblem statement: A portable X-ray elemental analyzer (total reflection X-ray fluorescence spectrometer) has been developed since 2006 and this spectrometer made it possible to perform ultra trace elemental determination. The intensity of scattered X-rays that become background noise in a spectrum is reduced with the improvement in surface accuracy of an X-ray reflector used in the portable spectrometer and therefore … …Current Research in Nanotechnology, Vol. 1, Issue 2 · 21 Jun 2011 · 7,293 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleOptimization of Energy Dispersive X-Ray Fluorescence Spectrometer to Analyze Heavy Metals in Moss SamplesMohd Zahari Abdullah, Ahmad Saat, Zaini HamzahProblem statement: Mosses had been widely used as bioindicator especially to study the levels of trace metals pollutants in the surrounding ambient air because of their high efficiency to accumulate heavy metals contamination. There had been increasing demand to get a suitable analytical tools to determine the chemical contents of moss samples in this type of media. This study was … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 3 · 18 Aug 2011 · 7,787 accessesView PDFCite

Rahman, Adnan Jusoh, Mohd. Zobir HusseinProblem statement: The significance of Kampung Sungai Mas as an importance archaeology site in Lembah Bujang was revealed in the year 1979 when a cannel was built along Kampung Sungai Mas area. During the construction study of this cannel, thousands of ceramic pieces from India, Middle East, China, Southeast Asia and Europe was discovered, pieces of glasses from Middle East … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 12 Dec 2011 · 9,839 accessesView PDFCite
Research ArticleOpen accessIn the keywordsEnvironmental Pollution by Heavy Metals in the Gold Mining Region of East CameroonDallou Guy Blanchard, Ngoa Engola Louis, Abdourahimi et al.The main objective of this study is to assess the level of heavy metals pollution in soil samples collected around gold mines located in Betaré Oya (BO) and Batouri (BA) in Eastern Cameroon. Elemental analysis of soil samples was carried out using Quant´X EDXRF spectrometer. Its sensitivity and accuracy were increased by using the Fundamental Parameter approach for quantification of … …American Journal of Environmental Sciences, Vol. 14, Issue 5 · 7 Nov 2018 · 9,777 accessesView PDFCite
Review ArticleOpen accessIn the abstractReview on Different Algorithms and Techniques Used in Classification of Gender in SilkwormJyoti Sharma, Pradeep ChoukseySilkworm seed is the key factor for the success of sericulture industry. Silk seed production process at grain ages centre mainly involve procuration of seed cocoon, cutting of seed cocoon for pupae, separation of male and female pupae, emergence of moth, coupling of silk moth and further egg laying by female moth. Separation of male and female is very much … …Journal of Computer Science, Vol. 21, Issue 6 · 17 Jun 2025 · 4,031 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Impact of XRF-Escape on Energy Resolution of NaI: Tl Scintillation Detectors for Medical Imaging or Gamma-Ray SpectroscopyRaffaele Scafè, Marco Puccini, Rosanna Pellegrini, Roberto PaniThe effect of escape of X-ray fluorescence from scintillator elemental components on the detector energy resolution is investigated from a spectroscopic standpoint, for monolithic and pixelated crystals. Along with these, any other emissions in a given region of interest were also considered. In present spectral evaluations a range of ratios between the areas of the peaks (XRFesc) to (XRFesc + … …American Journal of Applied Sciences, Vol. 21, Issue 1 · 10 Jul 2024 · 5,024 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Heavy Metals by using Industrial Waste by Products in Acid Mine DrainageNuur Hani Mohammed, Mustapha Atta, Wan Zuhairi Wan YaacubAcid Mine Drainage (AMD) is one of the main important problems being combated today. Laboratory tank experiments were conducted to evaluate the use of industry waste to adsorb and control the mobilization of metals from contaminated acid mine water. The main physical conditions such as pH and treatment performance are displayed. The solution of acid mine were sampled from the … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 18 Dec 2017 · 7,342 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessment of Strength Development in Stabilized Soil with CBR Plus and Silica SandSeyedesmaeil Mousavi, Aliakbar KaramvandThis paper investigates the potential use of a nano polymer stabilizer, namely CBR PLUS for stabilization of soft clay and formulation of an optimal mix design of stabilized soil with CBR PLUS and silica sand. The highway settlements induced by the soft clay are problematic due to serious damages in the form of cracks and deformation. With respect to this, … …American Journal of Applied Sciences, Vol. 15, Issue 4 · 12 Apr 2017 · 7,889 accessesView PDFCite
