Research ArticleOpen accessIn the abstractChloride Penetration Resistance Studies on Concretes Modified with Alkali Resistant Glass FibersK. Chandramouli, P. Srinivasa Rao, N. Pannirselvam et al.Problem statement: This research study presented the durability performance of glass fibre reinforced concrete. Approach: The influence of fiber content on the durability performance of glass fibre reinforced concrete specimens having different percentage of glass fibres with varying grades of concrete were investigated. Results: The parameter of investigation included rapid chloride permeability test for a period of 365 days. Specimens … …American Journal of Applied Sciences, Vol. 7, Issue 3 · 31 Mar 2010 · 7,253 accessesView PDFCite
Research ArticleOpen accessIn the abstractFeature Extraction for Characterization of Breast Lesions in Ultrasound Echography and ElastographyShirley Selvan, M. Kavitha, S. Shenbagadevi, S. SureshProblem statement: Elastography is developed as a quantitative approach to imaging linear elastic properties of tissues to detect suspicious tumors. We propose an automatic feature extraction method in ultrasound elastography and echography for characterization of breast lesions. Approach: The proposed algorithm was tested on 40 pairs of biopsy proven ultrasound elastography and echography images of which 11 are cystic, 16 … …Journal of Computer Science, Vol. 6, Issue 1 · 31 Jan 2010 · 8,315 accessesView PDFCite
Research ArticleOpen accessIn the abstractEvaluation of the Toxic Effects of Dihydroartemisinin on the Vital Organs of Wistar Albino RatsA. U. Utoh-Nedosa, P. A. Akah, T. C. Okoye, C. O. OkoliProblem statement: The current surge in the use of Artemisinin based Combination Therapy (ACT) in the treatment of falciparium resistant malaria in the tropics and the potentials of Dihydroartemisinin (DHA), a member of the artemisinin family, to produce toxic effect in the vital organs (such as the liver, heart, lungs, intestine, spleen kidney and blood cells) necessitated this research. Approach: … …American Journal of Pharmacology and Toxicology, Vol. 4, Issue 4 · 31 Dec 2009 · 9,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractImpedance Analysis of Heat Treated Polyethylene Oxide Polymeric Material for a Neural Storage ApplicationMahmoud Z. IskandaraniProblem statement: From the early days of, researchers have developed electronic models of neurons designed to emulate neural behavior with electrical signals that mimic in some ways the measured potentials of biological neurons. Researchers interested in fabricating artificial neurons have long sought a simple and techniques to produce devices that efficiently store synaptic weights, which is behind holding a particular … …American Journal of Applied Sciences, Vol. 6, Issue 7 · 31 Jul 2009 · 7,085 accessesView PDFCite
Research ArticleOpen accessIn the abstractEnhanced Survival and Nodule Occupancy of Pigeon pea Nodulating Rhizobium sp. ST1 expressing fegA Gene of Bradyrhizobium japonicum 61A152Falguni R. Joshi, Dhwani K. Desai, G. Archana, Anjana J. DesaiProblem statement: Rhizobial isolates belonging to genera (Rhizobium sp. and Mesorhizobium sp.) in our laboratory produced only catecholate type of siderophores. Although FhuA and FegA (ferrichrome receptors) homologs were found to be present in the sequenced genomes of few rhizobia (e.g., 1 in R. etli and 2 in Mesorhizobium sp. BNC1), laboratory isolates of the corresponding genera failed to utilize … …OnLine Journal of Biological Sciences, Vol. 9, Issue 2 · 30 Jun 2009 · 7,865 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrengthening of Corrosion-Damaged Reinforced Concrete Beams with Glass Fiber Reinforced Polymer LaminatesA. Leema Rose, K. Suguna, P. N. RagunathProblem statement: This study showed the results of an experimental investigation on the strengthening of corrosion damaged reinforced concrete beams with unidirectional cloth glass fiber reinforced polymer (UDCGFRP) laminates. Approach: All the beam specimens 150×250×3000 mm were cast and tested for the present investigation. One beam specimen was neither corroded nor strengthened to serve as a reference. Two beams were … …Journal of Computer Science, Vol. 5, Issue 6 · 30 Jun 2009 · 7,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractClassification by Discriminant Analysis of Energy in View of the Detection of Accented Syllables in Standard ArabicA. Chentir, M. Guerti, D. J. HirstProblem Statement: Current algorithms for the recognition and synthesis of Arabic prosody concentrate on identifying the primary stressed syllable of accented words on the basis of fundamental frequency. Generally, the three acoustic parameters used in prosody are: Fundamental frequency, duration and energy. Approach: In this study, we exploited the acoustic parameter of energy by means of a classification by a … …Journal of Computer Science, Vol. 4, Issue 8 · 31 Aug 2008 · 6,824 accessesView PDFCite
Research ArticleOpen accessIn the abstractOut of Focus Blur Estimation Using Genetic AlgorithmMohsen E. MoghaddamIn this study, we have presented a method to estimate out of focus blur that works in noisy images precisely. The presented method has been designed based on two rough estimates of blur function parameters and then the real parameter has been calculated using a genetic algorithm. The structure of out of focus function was analyzed in frequency domain to … …Journal of Computer Science, Vol. 4, Issue 4 · 30 Apr 2008 · 6,918 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffects of Carcass Weight and Muscle on Texture, Structure, Rheological Properties and Myofibre Characteristics of Roe DeerJoanna Żochowska-Kujawska, Kazimierz Lachowicz, Małgorzata Sobczak, Leszek GajowieckiMyofibre characteristic, texture, structure and rheological properties of selected muscles (BF, SM and L) of roe deer of different carcass weight were compared. Muscle texture and rheological properties was determined with the TPA and relaxation test, respectively, performed with a Instron 1140 device. Fibre type percentage and structural elements (muscle fibre cross sectional area and perimysium thickness) were measured in … …American Journal of Animal and Veterinary Sciences, Vol. 2, Issue 4 · 31 Dec 2007 · 7,579 accessesView PDFCite
