Research ArticleOpen accessEvery word in the titleSeasonal Variation of Soil Resistivity and Soil Temperature in Bayelsa StateJohn Tarilanyo Afa, C. M. AnaeleProblem statement: Due to the climatic variation for the year and it's sever harmattan during the month of December to March with the high keraunic level (80-90) in the areas, it was necessary to know the seasonal variation of soil resistivity. The seasonal variation and the nature of soil have considerable influence on electrical characteristics and therefore affect the earthling … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 5 Nov 2010 · 8,724 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleVariation in the Thickness of A Fluid Interface Due to Internal Wave Propagation: A Lattice Boltzmann SimulationJ.M. Buick, D.B. Hann, J.A. CosgroveThe change in the thickness of an interface between two immiscible fluids due to the propagation of an internal capillary-gravity wave along the interface is considered using a Bhatnagar, Gross and Krook (BGK) lattice Boltzmann model of a binary of fluid. The vertical thickness of the interface is recorded from the simulations since this is the most easily measured quantities … …American Journal of Applied Sciences, Vol. 1, Issue 1 · 31 Mar 2004 · 7,248 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCritical Amino Acid and Energy Balancing to Address MaizeGrade Variation in Broiler PerformanceMd. Shahidur Rahman, Muhammad Farhad Hossain, Million Maksuda et al.This study aimed to evaluate the effects of maize grade variationin broiler performance. A total of 189 Cobb 500 broilers were randomly andevenly assigned to three dietary treatments having three replications of 21 birds each. The treatments were: T0 (feed formulated with grade-A maize), T1 (feed formulated with grade-B maize, with Metabolizable Energy (ME) deficiencies compensated by additional Soybean Oil … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 2 · 10 Jul 2025 · 2,958 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleThree Dimensional Investigation of Mode I Stress Intensity Factor Variations in Crack Front Using Finite Element MethodM. M. MirsayarOverall failure may occur in many engineering structures due to the initiation and growth of cracks. Stress intensity factors are extensively used to investigate crack growth in Linear Elastic Fracture Mechanics (LEFM). In many cracked specimens, the stress singularity varies through the thickness and therefore, investigation of stress intensity factor variation in crack front and determination of its maximum value … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 1 · 26 Jan 2015 · 7,331 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAnalysis of Rheological Properties of MR Fluid Based on Variation in Concentration of Iron ParticlesVikram G. Kamble, Shreedhar KolekarThe main aim of this study is to synthesize magneto-rheological fluid in laboratory using silicon oil as carrier oil and it is mixed with variation in concentration of iron particles of size around 4-9 µm, fine lithium grease is used as surfactant. Prepared MR fluid is tested under plate and cone type rheometer for finding is rheological properties like shear … …Current Research in Nanotechnology, Vol. 5, Issue 2 · 14 Jan 2015 · 7,710 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleHEAVY 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 · 7,732 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIMAGE RETRIEVAL USING CERTAIN BLOCK BASED DIFFERENCE OF INVERSE PROBABILITY AND CERTAIN BLOCK BASED VARIATION OF LOCAL CORRELATION COEFFICIENTS INTEGRATED WITH WAVELET MOMENTSB. Thenkalvi, S. MurugavalliContent Based Image Retrieval (CBIR) is an evolving topic under image processing. Retrieval on medical images plays a vital role in saving mankind. Medical Content Based Image Retrieval (MCBIR) does not stop its work in displaying similar images; it also goes one step further for diagnosis to decide the method of therapy by comparing the query image and database image. … …Journal of Computer Science, Vol. 10, Issue 8 · 3 Apr 2014 · 6,979 accessesView PDFCite

Loss of biodiversity must be taken into account when proposing sustainable management actions for this resource. In this study we identified the morphological variants of this species, as well as the weight and Total Content of Reducing Sugars (TRS) in the stem of the agave. Approach: … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 4 · 21 Oct 2011 · 8,553 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenetic Variation and Relationship Between Turkish Flint Maize Landraces by RAPD MarkersA. OkumusA comparative characterization of 17 flint maize landraces (Zea mays L.) was carried out using RAPD markers. Fourteen primers giving reliable and consistent polymorphic bands amplified 125 fragments (89%) with an average of 8.90 fragment per primer.
