Research ArticleOpen accessIn the abstractAbout the Internal Structure of a Bone and its Functional RoleAntonio Apicella, Raffaella Aversa, Francesco Tamburrino, Florian Ion Tiberiu PetrescuThe human skeleton has the primary role of supporting all the organs that make up the body and at the same time to protect them permanently. It is made up so that it can hold and hold together all internal human organs, protecting them permanently, but also allowing them to move and exercise all their functionalities. This paper wants to … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 26 May 2018 · 8,402 accessesView PDFCite
Research ArticleOpen accessIn the abstractEquilibrium Studies and Optimization of Phosphate Adsorption from Synthetic Effluent Using Acid Modified Bio-SorbentBabayemi Akinpelu Kamoru, Onukwuli Okechukwu DominicAdsorption potential of periwinkle shell (PRW), an agricultural waste, for the removal of phosphate from aqueous solution was investigated through equilibrium studies at various experimental conditions. PRW was carbonized and chemically activated with 1MH2SO4 before it was subjected to characterization using Fourier Transform Infrared (FT-IR), Energy Dispersive X-ray (EDX) and Scanning Electron Microscopy (SEM). Adsorption data were analyzed using various … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 4 · 15 Dec 2017 · 7,666 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe 'Umbrella' Function Describing the Density of External Electrons Injected in NaCl CrystalSiti Wahyuni, Akrom Khasani, Wipsar Sunu Brams Dwandaru, Muhammad Farchani RosyidElectrons injected in NaCl crystal are studied using Thomas-Fermi-Dirac-von Weizsacker (TFDW) model. The external potential that contributes to the TFDW energy functional is not only due to the nuclei but also to the internal electrons. In order to obtain the potential term due to the internal electrons, the density of the internal electrons in the crystal is derived from the … …American Journal of Applied Sciences, Vol. 13, Issue 12 · 1 Dec 2016 · 8,296 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Improved Scheme for Digital Watermarking Using Functional Link Artificial Neural NetworkBanshidhar Majhi, Hasan ShalabiThe present study proposes a novel technique for copyright protection by utilizing digital watermarking of Images. The watermark is embedded and detected by using Functional Link Artificial Neural Network (FLANN) and Discrete Cosine Transform (DCT). The exhaustive simulation results of the proposed scheme show improved performance over the existing methods in all cases, i.e. when the watermarked image is subjected … …Journal of Computer Science, Vol. 1, Issue 2 · 30 Jun 2005 · 6,861 accessesView PDFCite
Research ArticleOpen accessIn the abstractCHARACTERIZATION OF OIL PALM EMPTY FRUIT BUNCH AND RICE HUSK BIOCHARS AND THEIR POTENTIAL TO ADSORB ARSENIC AND CADMIUMNorazlina Abu Sari, Che Fauziah Ishak, Rosenani Abu BakarBiochar as a new soil amendment has a potential in controlling the fate of trace elements in the soil system. However, the production of biochar from different feedstocks and pyrolysis conditions resulted in variable biochar properties which have an influence on trace elements availability. The experimental works are focused on physical and chemical properties of biochars produced from Empty Fruit … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 13 Aug 2014 · 10,585 accessesView PDFCite
Research ArticleOpen accessIn the abstractSYNTHESIS AND CHARACTERIZATIONOF ORGANIC FUNCTIONALIZED MESOPOROUS SILICA AND EVALUATE THEIR ADSORPTIVE BEHAVIOR FOR REMOVAL OF METHYLENE BLUE FROM AQUEOUS SOLUTIONSameer H. Kareem, Inaam H. Ali, M. G. JalhoomThree Mesoporous Silica (MPS) with different functional groups were prepared by one-step synthesis based on the simultaneous hydrolysis and condensation of tetraethoxy silane with organo-silane in the presence of template surfactant Polydimethylsiloxane-Polyethyleneoxide (PDMS-PEO). The prepared materials were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) and nitrogen adsorption-desorption experiments. The results indicate that the preparation of methyl and … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 28 Feb 2014 · 7,287 accessesView PDFCite
Research ArticleOpen accessIn the abstractLow Power Multiplier Design Using Latches and Flip-FlopsC. N. Marimuthu, P. ThangarajProblem statement: Power dissipation is designated as critical parameter in modern VLSI design field. In VLSI implementation low power concept is necessary to meet Moore’s law and to produce consumer electronics with more back up and less weight. To save significant power consumption of a VLSI design, it is a good direction to reduce its dynamic power which is the … …Journal of Computer Science, Vol. 6, Issue 10 · 30 Jul 2010 · 7,372 accessesView PDFCite
