Research ArticleOpen accessIn the abstractStudy on Optical Constants and Refractive Index Dispersion of Neutral red Doped Polymer FilmHussain A. BadranProblem statement: The some optical constants polymer thin film with red dye 3-amino-7-dimethylamino-2-methyl phenazine (NR) as the guest material and Polyvinylpyrrolidone (PVP) as the host material were prepared by adulteration and spin-coating methods. Approach: The values of some important parameters (refractive index n, extinction coefficient K and dielectric constant ε∞) of polymer thin film are determined from these spectra. Results: … …American Journal of Applied Sciences, Vol. 9, Issue 2 · 26 Dec 2011 · 8,923 accessesView PDFCite
Research ArticleOpen accessIn the abstractTheoretical Study of the Proton Transfer in EnaminonesRita Sabah EliasProblem statement: Hydrogen bonding has a vital rule to unrevealed the nature of many different interactions both in gas phase and condensed media thus it is one of the most important concepts in chemistry. Enaminoes with their ability to form intrahydrogen bonded cheated rings represent one of the suitable compounds to study such concept. Approach: The three possible tautomers of … …American Journal of Applied Sciences, Vol. 9, Issue 1 · 23 Nov 2011 · 7,421 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Data Mining Technique to Find Optimal Customers for Beneficial Customer Relationship ManagementG. Babu, T. BhuvaneswariProblem statement: Modern companies and organizations are efficiently implementing a CRM strategy for managing a company interactions and relationships with customers. CRM systems have been developed and designed to support the areas of marketing, service process and sales. Many literature studies are available to preserve the customer relationship but small drawbacks occur in the existing methods. One method to maintain … …Journal of Computer Science, Vol. 8, Issue 1 · 1 Nov 2011 · 7,263 accessesView PDFCite
Research ArticleOpen accessIn the abstractIncorporation of Bentazone with Exserohilum rostratum for Controlling Cyperus iriaFranklin Ragai Kundat, Loo Hong Shen, Osumanu Haruna AhmedProblem statement: Various methods are used to counter the population of Cyperus iria in rice fields and among the most common method are chemical approaches. Chemical control methods are preferred by rice farmers due to their efficacy, speed, ease of storage and affordable cost. The concern of chemical herbicides is on its effects on the environment. Less attention had been … …American Journal of Agricultural and Biological Sciences, Vol. 5, Issue 2 · 5 Sep 2011 · 9,529 accessesView PDFCite
Research ArticleOpen accessIn the abstractArthropods in Natural Communities in Mescal Agave (Agave durangensis Gentry) in an Arid ZoneMaría P. González-Castillo, Manuel Quintos Escalante, Gabriela Castaño-MenesesProblem statement: The arthropods have a very important role in the arid zones due to their interactions with many organism and because they constituted an important element in the structure of the plant community. Nevertheless their importance there are few knowledge about the community of arthropods associated to vegetation in arid zones in the North of Mexico. The present study … …American Journal of Applied Sciences, Vol. 8, Issue 10 · 20 Aug 2011 · 8,665 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntrahydrogen Bonding and Transition States Between Enol and Enethiol Tautomers in β-ThioxoketonesBahjat A. Saeed, Rita S. Elias, Ebraheem Abdu MusadProblem statement: Hydrogen bonding is one of the most important concepts in chemistry because it is crucial to understand many different interactions both in gas phase and in condensed media. A particular subset is presented by the intramolecular hydrogen bonds where two ends of the same molecule interact, resulting in a ringlike structure. Approach: The study involved theoretical investigation of … …American Journal of Applied Sciences, Vol. 8, Issue 8 · 18 Jul 2011 · 7,457 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructured Integration Test Suite Generation Process for Multi-Agent SystemZina Houhamdi, Belkacem AthamenaProblem statement: In recent years, Agent-Oriented Software Engineering (AOSE) methodologies are proposed to develop complex distributed systems based upon the agent paradigm. The implementation for such systems has usually the form of Multi-Agent Systems (MAS). Testing of MAS is a challenging task because these systems are often programmed to be autonomous and deliberative and they operate in an open world, … …Journal of Computer Science, Vol. 7, Issue 5 · 7 May 2011 · 7,452 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteractive Effects of the Feeding of Leucaena Leaves and Curcumin on Macronutrient Digestion and Nitrogen Balance in Beef CattleC. Yuangklang, J. Khotsakdee, K. Vasupen et al.Abstract: Problem statement: The feeding of curcumin to beef cattle has been shown to increase nitrogen retention and decrease the apparent digestibility of acid detergent fiber in beef cattle. It was suggested that there could be interactions between the effects of curcumin and the composition of the ration. Approach: In this study with beef cattle, concentrates without or with curcumin … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 1 · 15 Dec 2010 · 8,071 accessesView PDFCite
Research ArticleOpen accessIn the abstractOptimization of Clustering Time by a Group of Autonomous Robots Making Use of an Exclusive Multi-MarkingMohamed Rida Abdessemed, Kamel Khoualdi, Azeddine BilamiProblem statement: For solving complex issues, the current tendency goes towards the swarms behaviors, realized on a basis of collective interactions, which results from a cooperative work favoring exchanges between individuals of a same group at microscopic level and allowing the emergence of complex collective behaviors at macroscopic level. Many models were inspired by these attitudes to find simple rules, … …Journal of Computer Science, Vol. 6, Issue 12 · 9 Nov 2010 · 6,892 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling and Analysis of MRR, EWR and Surface Roughness in EDM Milling through Response Surface MethodologyA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) has grown over the last few decades from a novelty to a mainstream manufacturing process. Though, EDM process is very demanding but the mechanism of the process is complex and far from completely understood. It is difficult to establish a model that can accurately predict the performance by correlating the process parameters. The optimum … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 9,615 accessesView PDFCite
