Research ArticleOpen accessIn the abstractUsing Worldview-2 Satellite Imagery to Support Geoscience Studies on Phlegraean AreaPasquale Maglione, Claudio Parente, Andrea VallarioWorldView-2 satellite imagery includes half-meter panchromatic resolution and 2 m multispectral resolution. Because of the reduced dimensions of pixels and articulated spectral acquisition these images supply detailed information that can be used for geoscience applications, above all to investigate areas, identify land cover, bound vegetated zones, outline transformations (change detection). The aim of this study is to remark possibilities to … …Current Research in Geoscience, Vol. 3, Issue 1 · 4 Sep 2013 · 7,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractAutomatic Measurement of Drilling Parameters to Evaluate the Mechanical Properties of SoilsDaniele Pettinau, Pierpaolo Oreste, Marilena Cardu, Davide GuidarelliAny underground work, carried out either to perform excavations, should be based on detailed knowledge of the geological, hydrogeological and geomechanical conditions of the underlying materials. The continuous automatic diagraphy is a test that consists in the continuous surveying of drilling parameters, with total destruction of the core, which can be used, together with geognostic probing surveys and a detailed … …American Journal of Applied Sciences, Vol. 10, Issue 7 · 17 Jun 2013 · 7,553 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparative Analysis of Satellite Image Pre-Processing TechniquesT. Sree Sharmila, K. Ramar, T. SreeRenga RajaSatellite images are corrupted by noise in its acquisition and transmission. The removal of noise from the image by attenuating the high frequency image components, removes some important details as well. In order to retain the useful information and improve the visual appearance, an effective denoising and resolution enhancement techniques are required. In this research, Hybrid Directional Lifting (HDL) technique … …Journal of Computer Science, Vol. 9, Issue 2 · 1 Apr 2013 · 7,310 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Contribution of Art Museums to Art EducationBassam N. Al-RadaidehOver the years, in recognition of the need to increase opportunities for art education and art learning, schools have endorsed the value of museum learning and its role in facilitating knowledge acquisition and enriching the educational experience of students. Nevertheless, Jordanian schools ignored the enormous advantages of art museums and they consider them as an additional resource for classroom art. … …Journal of Social Sciences, Vol. 8, Issue 4 · 18 Mar 2013 · 8,252 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntioxidant Potential in Lipophilic and Hydrophilic Extracts from Medicinal Herbs (Salvia officinalis and Echinacea angustifolia). A Comparison Between Assays Based on Electron Paramagnetic Resonance and SpectrophotometryFlavia Navari-Izzo, Riccardo Izzo, Mike F. Quartacci et al.Recently, detection of antioxidant activity of plant extracts has caught the attention of researchers. Determination of antioxidant activity is usually performed using stable free radicals. A number of assays is available for screening the antioxidant activity of food constituents, but few of these methods are applicable to lipophilic substances. EPR is the analytical technique that directly measures free radicals making … …American Journal of Agricultural and Biological Sciences, Vol. 7, Issue 4 · 6 Nov 2012 · 9,013 accessesView PDFCite
Research ArticleOpen accessIn the abstractPro-Active Prevention of Clone Node Attacks in Wireless Sensor NetworksK. M. Anandkumar, C. JayakumarProblem statement: Wireless mobile sensor networks are deploying large, self-organized and adaptable sets of sensors for many applications such as military, environmental, health care, remote monitoring and other applications. Unfortunately, the simplicity and low-cost of these sensors make eases cloning of compromised nodes by attackers in the network. Due to the unattended nature of wireless sensor networks, an adversary can … …Journal of Computer Science, Vol. 8, Issue 10 · 28 Aug 2012 · 7,075 accessesView PDFCite
Research ArticleOpen accessIn the abstractAntibiotic Resistance and Chromium Reduction Pattern Among ActinomycetesPreeti Jain, Alina Amatullah, Samiul Alam Rajib, Hasan Mahmud RezaActinomycetes, one of the most important groups of microbes, exhibit many interesting activities such as degradation and transformation of organic and metal substrates together with production of antibiotics. With these bioactivities, actinomycetes would play an important role in the webs of the marine environment. The present study was designed to evaluate the antibiotic resistance pattern, antibiotic producing potential and chromium … …American Journal of Biochemistry and Biotechnology, Vol. 8, Issue 2 · 22 Jun 2012 · 8,908 accessesView PDFCite
Research ArticleOpen accessIn the abstractPalmprint Recognition using Feature Level FusionR. Gayathri, P. RamamoorthyProblem statement: Palmprint based biometric method has gained high impact over the other biometric methods due to its ease of acquisition, reliability and high client acceptance. Multiple feature extraction from image gives higher accuracy of the authentication system. Approach: This study presents the palmprint based identification methodology which uses the Gabor wavelet entropy to extract multiple features existing on the … …Journal of Computer Science, Vol. 8, Issue 7 · 19 May 2012 · 6,989 accessesView PDFCite
Research ArticleOpen accessIn the abstractStrains of Klebsiella Pneumoniae from Intensive Care Unit Producing CTX-M-15 Extended Spectrum Beta LactamasesI.R. Iroha, A.E. Oji, A.E. Nwakaeze et al.Problem statement: Resistance to third generation cephalosporins due to acquisition and expression of Extended Spectrum β-Lactamase (ESBL) among Gram-negative bacteria is on the increase. Infections involving extended spectrum beta lactamase bacteria are associated with significant morbidity and mortality. Therefore, infections due to ESBL isolates continue to pose a serious challenge to infection management worldwide. Since screening for ESBL is not … …Current Research in Microbiology, Vol. 2, Issue 2 · 6 Mar 2012 · 7,828 accessesView PDFCite
Research ArticleOpen accessIn the abstractEffect of Diurnally Cyclic Temperature on the Performance of a Continuous Mix Anaerobic DigesterAbdel E. Ghaly, Mariam T. Al HattabProblem statement: Concentrated livestock production is a major contributor to environmental problems through the production of large quantity of husks on relatively small land area. Anaerobic digestion represents a valuable means of cover by these husks into methane while reducing manure pollution problems. Methodology: An experimental apparatus, including data acquisition and control system, was developed and used to investigate the … …American Journal of Biochemistry and Biotechnology, Vol. 7, Issue 4 · 19 Jan 2012 · 9,230 accessesView PDFCite
