Research ArticleOpen accessIn the abstractComparisons of Phytotoxicity of Barley Parts Extracts in Three Growth Stages on Annual RyegrassKolahi Maryam, Kolahi MinaProblem statement: The importance of allelopathy in nature and in agroecosystem has attracted researcher's attention with the main goal of using the phenomenon in biological control of weeds. currently, active involvement of scientists from different disciplines made allelopathy a multidisciplinary subject, and transformed the research from basic to applied, enabling use of allelopathy in agriculture and forestry. Screening accessions of … …American Journal of Agricultural and Biological Sciences, Vol. 3, Issue 4 · 31 Dec 2008 · 7,602 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectric Voltage Control as an Implementation of Neural Network ApplicationsA. A. Al-Rababah, U. A.Al-RababahPresent study was proposed the monitoring of mathematical model of electric voltage source with using neural network for application in control systems as sensor and command signal. The monitoring system, consist of toroidal choke or transformer with high saturated ferromagnetic cores. The input information we receive from current periodic curves. The current was distributed into Fourier or walsh series. The … …Journal of Computer Science, Vol. 4, Issue 10 · 31 Oct 2008 · 6,297 accessesView PDFCite
Research ArticleOpen accessIn the abstractSkeleton Primitive Extraction Method on Textures with Different Nonlinear WaveletsV. V. Kumar, U. S.N. Raju, P. Premchand, A. SureshProblem Statement: A novel method for dominant skeleton extraction of textures using different nonlinear wavelet transforms is proposed in this study. In the present study 3×3 masks are used for extraction of skeleton primitives. For a 3×3 skeleton primitive there will be 29 skeleton primitive combinations. But the present study considered a skeleton primitive for the skeletonization purpose if and … …Journal of Computer Science, Vol. 4, Issue 7 · 31 Jul 2008 · 6,815 accessesView PDFCite
Research ArticleOpen accessIn the abstractPower Series Solution for a Two-step Reactive-diffusive Equation with Variable Pre-exponential FactorE.A. Adebile, O.K. Koriko, U.S. IdiongWe discussed in this research a power series method for solution of a two-step reactive-diffusive equation with variable pre-exponential factor. A transformation was used to fit in the geometry of the model to allow an asymptotic series expansion which is invoked in a two compartmental regions with respect to the spatial variable. Adequate matching conditions were used at the interface … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 6,855 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Survey of Content-Based Video RetrievalP. Geetha, Vasumathi NarayananThis study surveys current trends/methods in video retrieval. The major themes covered by the study include shot segmentation, key frame extraction, feature extraction, clustering, indexing and video retrieval-by similarity, probabilistic, transformational, refinement and relevance feedback. This work has done in an aim to assist the upcoming researchers in the field of video retrieval, to know about the techniques and methods … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 8,580 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Database System Model Design for Tender Management SystemA. Noraziah, R. Norhayati, Ahmed N. Abdalla et al.This research focus on the software design and database system model for Tender Management System (TMS) in Kadastra. TMS in Kadastra is an automated system that can calculates tender payment claims for the land surveyor company. The calculation is based on the Vide Federal Government Gazette PU (A) 169 Thirteenth Schedule (Regulation 99) Scale of Fees for Title Surveys given … …Journal of Computer Science, Vol. 4, Issue 6 · 30 Jun 2008 · 6,597 accessesView PDFCite
Research ArticleOpen accessIn the abstractThree Dimensional Hydrodynamic Model With Multiquadtree MeshesGregorio Posada Vanegas, Rodolfo Silva Casarín, Sébastien de BryeThis study presents a three dimensional model for the transport of conservative contaminants, which can be used for bodies of water which are affected by winds and/or tides. The model solves the equation of mass transport, based on results obtained using a hydrodynamic model for shallow waters that works in a finite volume scheme and a type of hierarchical grid, … …American Journal of Environmental Sciences, Vol. 4, Issue 3 · 30 Jun 2008 · 6,584 accessesView PDFCite
Research ArticleOpen accessIn the abstractPlants Responses to Nutrients Follow the Saturation Kinetic Typical of Enzyme Systems: Biological, Economical and Environmental ImplicationsR.P. LanaAgricultural efficiency has been associated with high plant productivity. However, it is dependent on fertilizers, which are nonrenewable resources. Crop production response to fertilizers is hyperbolic, following the Michaelis-Menten model and the law of diminishing return. Data of crop production (barley, bean, corn, cotton, soybean and wheat) as a function of nitrogen, phosphorus, and potassium fertilization were analyzed by Lineweaver-Burk … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 6,898 accessesView PDFCite
Research ArticleOpen accessIn the abstractHow Greece and Ireland Have Been Positioned in the World Developments Since 1945: A French Regulation ApproachLavrentios VasiliadisThis research analyses how Greece and Ireland have been positioned in the world development since 1945 by using the French Regulation Approach. In particular, this analysis describes three broad periods, notably the Fordist, post-Fordist and the New Economy ones. In each period, apart from the general approach that concerns the world economy transformation, the specific transformations of the economies of … …Journal of Social Sciences, Vol. 4, Issue 1 · 31 Mar 2008 · 7,362 accessesView PDFCite
Research ArticleOpen accessIn the abstractCancer may be caused by the Immune ReactionRichmond T. PrehnHormesis-like effects of immunity have been documented during tumor-growth experiments in mice, quantitatively large immune-reactions have inhibited while lesser quantities of the same specific immune-reactants have been stimulatory to the growth of implanted tumors. Likewise, carcinogenesis has been inhibited by a high quantities of immune reactants, but positively stimulated by lower levels of the same reactants. One observation suggests that … …American Journal of Pharmacology and Toxicology, Vol. 3, Issue 1 · 31 Mar 2008 · 7,462 accessesView PDFCite
