Research ArticleOpen accessIn the abstractInduced Microcracking Affects Osteoblast Attachment on Hydroxyapatite Scaffolds for Tissue EngineeringIan O. Smith, Melissa J. Baumann, Eldon D. CaseBone microdamage caused by routine activity plays an important role in triggering targeted and nontargeted bone remodeling. Targeted remodeling occurs near localized areas of microdamage[1-4]. We hypothesize that bone remodeling may be directly and positively influenced by inducing microcracks in hydroxyapatite (HA) scaffolds for bone tissue engineering. A study by Case et al. showed microcracking in HA discs having >98% … …American Journal of Biochemistry and Biotechnology, Vol. 2, Issue 3 · 30 Sep 2006 · 6,560 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Use of Real Options Methodology to Pasturelands EvaluationA. Michailidis, F. Chatzitheodoridis, I. Mountousis, K. PapanikolaouThis study demonstrates the utility of the real options approach to pasturelands investment analysis. The main objectives are to discuss the real options theory and show how it can be adopted to model uncertainty and managerial flexibility in pasture management (enlargement plan) and investment. Secondly, we show how to calculate the option values of selected options that may be available … …American Journal of Applied Sciences, Vol. 3, Issue 8 · 31 Aug 2006 · 6,766 accessesView PDFCite
Research ArticleOpen accessIn the abstractRadiation Measurement from Mobile Base Stations at a University Campus in MalaysiaMd. Rafiqul Islam, Othman O. Khalifa, Liakot Ali et al.The tremendous growth of telecommunication industry results the number of hand phone users increases everyday. In order to support the growing number of users, the mobile base stations can be seen in almost everywhere. This scenario has created uncomfortable feelings to the people that they may be affected by the radiations from antennas. A measurement was done at student hostels … …American Journal of Applied Sciences, Vol. 3, Issue 4 · 30 Aug 2006 · 7,292 accessesView PDFCite
Research ArticleOpen accessIn the abstractConstruction of a Glucose Biosensor by Immobilizing Glucose Oxidase within a Poly(o-phenylenediamine) Covered Screen-printed ElectrodeMiao Yuqing, Chen Jianrong, Wu XiaohuaThe glucose biosensors were prepared by the electropolymerization of the non-conductive polymer, Poly(o-phenylenediamine), onto a planar screen-printed electrode. A fabrication procedure was performed to decrease the waste of expensive enzyme. The amperometric glucose response was measured by the potensiostating of the prepared glucose biosensors at a potential of 0.3 V with ferrocene as mediator. Results show that the obtained biosensors … …OnLine Journal of Biological Sciences, Vol. 6, Issue 1 · 30 Jun 2006 · 6,843 accessesView PDFCite
Research ArticleOpen accessIn the abstractLeishmania donovani: Immunomodulatory Role of 63KDa Leishmania Antigen in the Promotion of IFN-gamma Response (VL vs HIV-VL Co-infection)Pranati, Sanjiva Bimal, K. Pandey et al.Cytokine behavior of T-lymphocytes is not very clear when a patient is co-infected with Leishmania donovani and HIV. To achieve this we studied groups of patients comprising of VL infected, HIV infected and HIV-VL co-infected cases. As compared to lone infections by either of the infecting agent, the co-infection cases showed greatly diminished CD4 T-cell counts and slightly enhanced values … …American Journal of Immunology, Vol. 2, Issue 2 · 30 Jun 2006 · 7,005 accessesView PDFCite
Research ArticleOpen accessIn the abstractResearch Note: Standard Scores Based on the Median and Inter-quartile RangeJames CarifioRecently when asked to help with statistical analyses of the Medicare Provider Analysis and Review (MEDPar) Data, I encountered a common statistical and analytical problem with this national database, which is also common to many national and health databases. This problem was the problem of extremely skewed distributions (g1 and/or g2 typically exceeding 20), which creates numerous difficulties in comparing … …Journal of Mathematics and Statistics, Vol. 2, Issue 1 · 31 Mar 2006 · 6,843 accessesView PDFCite
Research ArticleOpen accessIn the abstractDesign of a Neural Networks Classifier for Face DetectionF. Smach, M. Atri, J. Mitéran, M. AbidFace detection and recognition has many applications in a variety of fields such as security system, videoconferencing and identification. Face classification is currently implemented in software. A hardware implementation allows real-time processing, but has higher cost and time to-market. The objective of this work was to implement a classifier based on neural networks MLP (Multi-layer Perception) for face detection. The … …Journal of Computer Science, Vol. 2, Issue 3 · 31 Mar 2006 · 6,887 accessesView PDFCite
Research ArticleOpen accessIn the abstractEstimating the Optimal Farm Size under Uncertainty: an Application of Real Options MethodologyAnastasios Ch. Michailidis, Konstadinos A. MattasFarm structure and optimal farm size have always attracted the interest of research as they constitute some of the intense problems of farm efficiency and farm income. Although several approached have been employed to handle with this problem a real options approach can significantly contribute on this matter. This article provides an empirical example of applying real options approach in … …American Journal of Agricultural and Biological Sciences, Vol. 1, Issue 1 · 31 Mar 2006 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Comparison of Spatio-Temporal Bayesian Models for Reconstruction of Rainfall Fields in a Cloud Seeding ExperimentSujit k. sahu, Giovanna Jona Lasinio, Arianna orasi, Kanti V. MardiaIn response to the drought experienced in Southern Italy a rain seeding project has been setup and developed during the years 1989-1994. The initiative was taken with the purpose of applying existing methods of rain enhancement technology to regions of south Italy including Puglia. The aim of this study is to provide statistical support for the evaluation of the experimental … …Journal of Mathematics and Statistics, Vol. 1, Issue 4 · 31 Dec 2005 · 6,813 accessesView PDFCite
Research ArticleOpen accessIn the abstractA New Compressing Ultrasonic Data Algorithm Based on WaveletsMounir Hergli, Jamel Baili, Faouzi Bouslama, Kamel BesbesIn this paper, we propose a novel and effective algorithm for compressing large volumes of data recorded in underwater applications, using a laboratory designed experimental setup. This data represents samples of ultrasonic signals acquired at different geometric positions of a water tank. The proposed algorithm was based on Wavelets and consists of two processing phases including a prefiltering stage using … …American Journal of Applied Sciences, Vol. 2, Issue 12 · 31 Dec 2005 · 7,002 accessesView PDFCite
