Research ArticleOpen accessIn the abstractThe Bioaccumulation and Detoxification Mechanism of Neodymium on the Shoot of Rice SeedlingsKailun Shi, Cheng Kun Liu, Keliang Lyu et al.Neodymium (Nd) potentially pollutes environment for its wide usage in agriculture and industry. In this study, the chemical forms of Nd and effect of Nd on rice shoots were studied after rice seedlings were exposed with 0, 1, 10, 100 and1000 μM Nd. The higher concentration of Nd inhibited shoot growth, but the lower concentration of Nd induced shoot growth. … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 11 Apr 2021 · 6,291 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Forensic Profiling of Primer-Derived Inorganic Gunshot Residues Using SEM-EDX SpectroscopyAhmed M. Bendary Salem, Aldo Barbaro, Bolaji OladipoGunshot Residue (GSR) analysis presents a significant challenge in forensic science due to the need to detect and identify minute traces of powders and initiating compositions formed during the chemical decomposition and deflagration processes within cartridge cases. This research is a qualitative comparative profiling study, designed to create a reference database of the most characteristic elemental markers for commonly used … …American Journal of Applied Sciences, Vol. 22, Issue 1 · 6 Mar 2026 · 2,726 accessesView PDFCite
Research ArticleOpen accessIn the abstractDirect Geometry and Cinematic to the MP-3R SystemsRelly Victoria Petrescu, Raffaella Aversa, Bilal Akash et al.Mechatronic robotic systems are today widely used worldwide to ease human work, but especially where work is dangerous, in toxic, radioactive, chemical, explosive atmospheres, without air such as underwater or in the cosmos, or in places hard to reach the man. Robots can take the tedious repetitive work under any circumstances and they can perform a difficult operation for a … …Journal of Mechatronics and Robotics, Vol. 1, Issue 1 · 23 Nov 2017 · 7,511 accessesView PDFCite
Research ArticleOpen accessIn the abstractSpecific Features of the Accumulation and Distribution of Heavy Metals in Soils of the Floodplain and Deltaic Landscapes of the Don RiverTatiana M. Minkina, Dina G. Nevidomskaya, Yuriy A. Fedorov et al.The purpose of this work was to study specific features of the accumulation and distribution of the total content and mobile forms of Heavy Metals (HM) in soils of the estuarine ecosystems of the floodplain and deltaic landscapes of the Don River. The results allowed us to detect regional specific features in the formation of HM compounds in floodplain soils … …American Journal of Applied Sciences, Vol. 12, Issue 11 · 19 Nov 2015 · 6,586 accessesView PDFCite
Research ArticleOpen accessIn the abstractNATURE TOURISM PLANNING USING RIVER-BASED RESOURCES AND RECREATIONAL ASSESSMENT FOR SUNGAI DINDING, PERAK, MALAYSIAAhmad Ainuddin Nuruddin, Ali Muhammad AliRivers and stream corridors provide a variety of valuable resources including aquatic habitats for fish and other organism, riparian habitats for fish and other organism, riparian habitats for vegetation and terrestrial wildlife. They also provide potential recreational and nature tourism activities. In order to fully identify potential recreational and activities, assessment of recreation resource element should be carried out.

Research ArticleOpen accessIn the abstractSugar Beet Performance Affected by Uniformity of N FertigationH. Nouri, M. S.M. Amin, S. J. Razavi et al.In common with the majority of crop species, in sugar beet nutrition nitrogen is an important element due to its role in sucrose utilization and plant growth. Application of precision agriculture, in order to apply the right amount of input at the right time in the right area, is appropriate to decrease chemical use and increase plant growth. Problem statement: … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,931 accessesView PDFCite
HypothesisOpen accessIn the abstractNew Opportunities for Fullerenes and for GrapheneClive DelmonteThis is a conjecture which defines a new class of electrically conducting polymer that chemically confines metals, ions or clusters within an electric potential constraining them to react in ways novel to chemistry. The polymers are planar on a planar surface and adhere as a П-bonded electron sheet to planar, electron-delocalized surfaces as in Fullerenes, graphene (both sides) and graphite. … …Current Research in Nanotechnology, Vol. 6, Issue 2 · 1 Jan 2016 · 13,958 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization 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.
