Research ArticleOpen accessIn the abstractEfficient Data Compression Scheme using Dynamic Huffman Code Applied on Arabic LanguageSameh Ghwanmeh, Riyad Al-Shalabi, Ghassan KanaanThe development of an efficient compression scheme to process the Arabic language represents a difficult task. This paper employs the dynamic Huffman coding on data compression with variable length bit coding, on the Arabic language. Experimental tests have been performed on both Arabic and English text. A comparison is made to measure the efficiency of compressing data results on both … …Journal of Computer Science, Vol. 2, Issue 12 · 31 Dec 2006 · 7,244 accessesView PDFCite
Research ArticleOpen accessIn the abstractSurface Roughness Prediction Model in Machining of Carbon Steel by PCD Coated Cutting ToolsYusuf Sahin, A. Riza MotorcuThe surface roughness model in the turning of AISI 1040 carbon steel was developed in terms of cutting speed, feed rate and depth of cut using response surface methodology. Machining tests were carried out using PVD-coated tools under different cutting conditions. The surface roughness equations of cutting tools when machining the carbon steels were achieved by using the experimental data. … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,968 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordSerum TGF-β and TNF-α During Psoriasis Therapy with Narrowband Ultraviolet BAhmad Taha Khalaf, Yan YuehuaAlthough it is now an accepted concept that narrow-band UVB therapy is an efficacious therapy for psoriasis, the relationship between the response rate and the potential effects on serum cytokines is less well-established. The purpose of this study was to investigate the correlation between the response rate and the changes of serum TGF-β and TNF-α necessary for understanding the underlying … …American Journal of Applied Sciences, Vol. 11, Issue 12 · 6 Jan 2015 · 6,095 accessesView PDFCite
Case ReportOpen accessAll words, across the recordConsumption of an Extremely Biodiverse Probiotic and a Supplement based on Microbial Chondroitin Sulfate is Associated with Very Low Serum Alpha-N-acetylgalactosaminidase (Nagalase) Activity and Decrease of C-reactive Protein ValuesMichael Carter, Stefania Pacini, Marco RuggieroWe describe the case of a 57-years-old male healthy professional who added to his nutritional plan a novel, extremely biodiverse, probiotic and a supplement based on microbial chondroitin sulfate, vitamin D3 and ultrapure phosphatidylcholine to improve his healthy life expectancy. After three months of such a nutritional regimen, serum alpha-N-acetylgalactosaminidase (nagalase) activity was 0.40 that is a value below the … …American Journal of Immunology, Vol. 16, Issue 1 · 22 Apr 2020 · 13,055 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEnvironmental 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 · 9,780 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordEffect of Intraperitoneally Injection of Different Doses of Lovastatin on Pain and Inflammatory Response Induced by Formalin in MiceKhayatnouri MirhadiProblem statement: The 3-Hydroxy-3-Methyl Glutaryl-CoA (HMG-CoA) reductase inhibitors (statins) have been unequivocally shown to reduce cardiovascular morbidity and mortality. Their lipid-lowering actions are by reversible and competitive inhibition of the enzyme HMG-CoA reductase, a precursor of cholesterol. It has been suggested that statins appear to have therapeutic benefits in diseases that are unrelated to elevated serum cholesterol levels, such as … …American Journal of Animal and Veterinary Sciences, Vol. 6, Issue 4 · 11 Jan 2012 · 7,685 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordGeochemistry of Sediment in the Major Estuarine Mangrove Forest of Terengganu Region, MalaysiaB.Y. Kamaruzzaman, M.C. Ong, M.S.Noor Azhar et al.Surface sediments collected from seven estuarine mangrove forests of Terengganu region (100 sampling points) were anaylzed for Pb, Cu and Zn using the sensitive Inductively Coupled Plasma Mass Spectrometer (ICP-MS). The average concentration of Pb, Cu and Zn were 10.5±7.12 µg g-1 dry weights, 31.1±16.5 µg g-1 dry weights and 20.8±13.3 µg g-1 dry weights, respectively.
