Research ArticleOpen accessEvery word in the titleExtraction of Ca(II) and Mg(II) from Hydrochloric Acid Solutions by N,N-Dioctyl-1-Octanamine in Methyl Isobutyl KetoneFatmir Faiku, Arben I. Haziri, Haxhere FaikuProblem statement: Amines as organic molecules are able to form complexes with metals ions and this is the reason why we can use them to extract metals ions from hydrometallurgical solutions. Approach: Based on that, we have investigated the extraction of Calcium and Magnesium with N,N-dioctyl-1-octammine from the mixture of elements prepared in artificial manner. We investigated the influence of … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,439 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleAn Improved Handwritten Tamil Character Recognition System using Octal GraphR. J. Kannan, R. PrabhakarProblem Statement: Handwriting recognition has attracted voluminous research in recent times. The segmentation and recognition of the characters from handwritten scripts incorporates considerable overhead. Almost all the existing handwritten character recognition techniques use neural network approach, which requires lot of preprocessing and hence accomplishing these problems using neural network is a tedious task. Approach: In this study we propose a … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 7,405 accessesView PDF Cite

Approach: Based on that, we have investigated the extraction of Calcium and Magnesium with N, N-dioctyl-1-octan ammonium chloride from the mixture of elements (Ca and Mg) prepared in artificial … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 8 Jun 2012 · 7,592 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleGPS Ionospheric Total Electron Content and Scintillation Measurements during the October 2003 Magnetic StormMohammad Awad Momani, Takialddin A. Al Smadi, Farouq M. Al Taweel, Khaldoon A. GhaidanProblem Statement: Ionospheric scintillations, cause significant effects on satellite signals for communication and navigation in equatorial region and polar regions mainly during sever magnetic storms periods. This phenomenon is not fully understood due to few studies performed. The study investigates variability of Total Electron Content (TEC) and ionospheric scintillation during October 2003 magnetic storm over Antarctica using ground based GPS … …American Journal of Engineering and Applied Sciences, Vol. 4, Issue 2 · 13 Jul 2011 · 8,508 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleProduction of (E) 10-Hydroxy-8-octadecenoic Acid with Lyophilized Microbial CellsA. Bódalo, J. Bastida, M.F. Máximo et al.Lyophilized non-proliferating microbial cells of Pseudomonas sp. 42A2 showed their ability to catalyze the bioconversion of oleic acid into (E)-10-hydroxy-8-octadecenoic acid (MHOD) and (E)- 7,10-dihydroxy-8-octadecenoic acid (DHOD). The reaction conditions were optimized in order to produce the maximum amount of MHOD. At 30°C and using phosphate buffer (0.1 M and pH=8), an initial substrate concentration of 10 mg mL-1 and … …American Journal of Biochemistry and Biotechnology, Vol. 1, Issue 1 · 31 Mar 2005 · 7,162 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsHuffman Based Code Generation Algorithms: Data Compression PerspectivesAhsan Habib, M. Jahirul Islam, M. Shahidur RahmanThis article proposes two dynamic Huffman based code generation algorithms, namely Octanary and Hexanary algorithm, for data compression. Faster encoding and decoding process is very important in data compression area. We propose tribit-based (Octanary) and quadbit-based (Hexanary) algorithm and compare the performance with the existing widely used single bit (Binary) and recently introduced dibit (Quaternary) algorithms. The decoding algorithms for … …Journal of Computer Science, Vol. 14, Issue 12 · 9 Dec 2018 · 7,701 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsNON-INVASIVE OPTICAL METHOD FOR EPIDERMAL THICKNESS ESTIMATIONAdrian Pena, Miguel Arronte, Eduardo De Posada et al.A non-invasive method to determine epidermal thickness from the intensity of transmitted visible light is proposed. A simple model for passing light through the epidermis layers, then measuring what is transmitted back out of the surface, is implemented by using the Montecarlo method. Simulations revealed that the transmittance is linearly dependent on the thickness of the epidermis and so demonstrated … …OnLine Journal of Biological Sciences, Vol. 14, Issue 2 · 25 Jun 2014 · 7,478 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsThe Role of SLC22A4 Gene Polymorphisms in the Response to Salbutamol in Asthmatic PatientsAlshymaa A. Ahmed, Nora M. Said, Alia A. El Shahaway, Nagwan A. IsmailResponse to Bronchodilators is influenced by many factors including genetics. To evaluate the influence of SLC22A4 gene polymorphisms (rs3792876 and rs2073838) on the response to inhaled salbutamol in asthmatic patients, bronchodilator response was assessed in 180 bronchial asthma patients via measuring changes of the Forced Expiratory Volume in one second (FEV1) after the administration of inhaled salbutamol and genotyping for … …American Journal of Immunology, Vol. 15, Issue 1 · 30 Jun 2019 · 7,470 accessesView PDF Cite
