Research ArticleOpen accessAll words, across the recordVerification of Anchoring in Foundations of Wind Turbine TowersNafsika Stavridou, Evangelos Efthymiou, Charalampos C. BaniotopoulosTubular steel towers are the most common supporting structure of wind converters. The towers’ foundation covers an important part of the initial cost and its configuration depends heavily on the type of subsoil. Onshore structures are founded on spread footing foundations or pile foundations with the first being the commonest. In these spread footing foundations, the tower is either embedded … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 23 Nov 2015 · 8,398 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordWelded Connections of Wind Turbine Towers under Fatigue Loading: Finite Element Analysis and Comparative StudyNafsika Stavridou, Evangelos Efthymiou, Charalampos C. BaniotopoulosIncreased contemporary energy needs have led to multiple investments on wind power plants and structural improvements are considered necessary for the construction of taller, more robust and more economical structures. Tubular steel wind turbine towers that are the prevailing structural configuration, demand welding of circular subparts to construct the tower structure. These circumferential welds between tower subparts and between the … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 4 · 18 Aug 2015 · 8,899 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordHEAVY METAL ANALYSIS IN RED OAK (QUERCUS RUBRA) POPULATIONS FROM A MINING REGION IN NORTHERN ONTARIO (CANADA): EFFECT OF SOIL LIMING AND ANALYSIS OF GENETIC VARIATIONAnh Tran, K. K. Nkongolo, M. Mehes-Smith et al.Understanding the dynamic of metals in soil and plants and population diversity in Northern Ontario is essential in determining progress toward ecosystem sustainability in reclaimed sites. The objectives of the present study were to assess the levels of metal content in soils and their accumulation in red oak plants from limed and unlimed sites. Genetic variation in red oak populations … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 25 Jun 2014 · 7,737 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordOptimization 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 · 7,793 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. The statistical analysis of … …American Journal of Applied Sciences, Vol. 5, Issue 12 · 31 Dec 2008 · 7,323 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordFactor Affecting Technical Efficiency of Smallholder Rubber Farming in Northeast ThailandS. Poungchompu, S. ChantanopWith the increase of rubber production, Para rubber farmers in Northeastern Thailand have faced the limited physical and socio-economic conditions that have given rise to the improvement of technical efficiency. This study investigated the technical efficiency of Para rubber farmers. A multi-stage random sampling technique was used to collect cross sectional data on 300 farmers. The data was analyzed using … …American Journal of Agricultural and Biological Sciences, Vol. 10, Issue 2 · 24 Jun 2015 · 8,655 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordACCUMULATION OF RADIONUCLIDES BY PYLAISIELLA MOSS (PYLAISIA POLYANTHA) UNDER URBOECOSYSTEM CONDITIONST. V. Varduni, T. M. Minkina, E. A. Buraeva et al.Contamination of environment by radionuclides in territories under urboecosystem conditions is actual problem. The search of new express methods for radioactivity determination of environment is important task of research. In present work it was shown that mosses are bioindicators of radioactive contamination, because they accumulate radioactive substances in high concentrations. Using of bryoindication methods are promising techniques for the assessment … …American Journal of Applied Sciences, Vol. 11, Issue 10 · 1 Dec 2014 · 6,455 accessesView PDFCite
