Research ArticleOpen accessIn the abstractThe Effect of Acute Administration of Artemisia Persia Extracts on Arterial Blood Pressure and Heart Rate in RatsFarzaneh Esmaeili, Gholamreza Sepehri, Ghollam-Reza Moshtaghi-Kashanian et al.Problem statement: Artemisia Persia (AP) used for its therapeutic effects in folk medicine whiles some species of Artemisia shown a hypotensive effect. To determine the cardiovascular effect of AP, we tested the pharmacological responses of aqueous and methanolic extracts of AP on blood pressure (BP) and Heart Rate (HR) of normotensive and ephedrine induced hypertensive rats using a tail-cuff computerized … …American Journal of Applied Sciences, Vol. 6, Issue 5 · 31 May 2009 · 7,654 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Assessment of the Electric Power Quality and Electrical Installation Impacts on Medical Electrical Equipment Operations at Health Care FacilitiesMário César Giacco Ramos, Carlos Márcio Vieira TahanProblem statement: Medical electrical equipments at health care facilities presented malfunction and wrong medical information due to poor electric power quality and to inadequate electrical Installations. Some equipment such as X-ray, computerized axial tomography and magnetic resonance imaging are considered as polluting ones due to their high amount of harmonics and voltage transients produced on the electrical power supply when … …American Journal of Applied Sciences, Vol. 6, Issue 4 · 30 Apr 2009 · 7,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe New Variable-Length Key Symmetric CryptosystemDavood Rezaei Pour, Mohamad Rushdan Md Said, Kamel Ariffin Mohd Atan, Mohamed OthmanProblem statement: In this study, we proposed a new 64-bit block cipher that accepted a variable-length key up to 512 bits, which was suitable for implementation in a variety of environments. Approach: The cipher algorithm was a 16-round Feistel network with a bijective function f and was made up of two key-dependent 16×16 S-boxes, bitwise rotations, and a carefully designed … …Journal of Mathematics and Statistics, Vol. 5, Issue 1 · 31 Mar 2009 · 7,213 accessesView PDFCite
Research ArticleOpen accessIn the abstractPossibility of High Performance Quantum Computation by using Evanescent Photons in Living SystemsTakaaki MushaPenrose and Hameroff suggested that microtubles in living systems functioned as quantum computers by utilizing evanescent photons. On the basis of the theorem that the evanescent photon is a superluminal particle, the possibility of high performance computation in living systems has been studied. From the theoretical analysis, it is shown that the living system can achieve large quantum bits computation … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 6,359 accessesView PDFCite
Research ArticleOpen accessIn the abstractObject Based Video Analysis, Interpretation and TrackingA. Umamakeswari, A RajaramanThe role of computers in different facets of human life is increasing everyday, from one of supplementing his needs to one of integrating in the different activities, he is involved. This has become more predominant with the prolific developments in communication and internet. This brings in a need to raise the level of computers to the level of human beings … …Journal of Computer Science, Vol. 3, Issue 10 · 31 Oct 2007 · 6,680 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntroducing Radio-Opaque Radio-Lucent Graduated Root Canal Length Indicating Cones (GRCLIC) in EndodonticsMohammad Rashid Shahidi BonjarRadio Opaque-Radiolucent Graduated Root-Canal Length Indicating Cone (GRCLIC) is a new innovative device being introduced for the first time in endodontics literature. GRCLIC can present more accurate measurement of the root canal length in conventional radiographs in endodontic and root canal treatment. Like many other dental and medical specialties, endodontics has evolved and changed over the years. The changes that … …American Journal of Applied Sciences, Vol. 4, Issue 8 · 31 Aug 2007 · 7,095 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoving Useless Productions of a Context Free Grammar through Petri NetMansoor Al-A'ali, Ali A. KhanFollowing the proposal for a Petri Net (PN) representation of the Context Free Grammar (CFG)[1], we propose in this paper, an algorithm to eliminate the useless productions of CFG. First the CFG is represented by a PN. Then, based on the reachability, an algorithm is developed to eliminate Useless-productions. The algorithm is analyzed and implemented in Pascal using examples of … …Journal of Computer Science, Vol. 3, Issue 7 · 31 Jul 2007 · 6,670 accessesView PDFCite

Research ArticleOpen accessIn the abstractInvestigation of An Acoustic Temperature Transducer and its Application for Heater Temperature MeasurementMohammad A.K. Alia, Tariq Al MograbiRecent developments in temperature measurement have encouraged researchers to develop low-cost, simple structure, computerized generic transducers for environmental monitoring and industrial process control. The research presents a computerized technique which allows to measure temperature according to the variation of acoustic velocity (frequency) in a closed waveguide. Signal conditioning and processing was carried out using labVIEW (G Language) VIs. In order … …American Journal of Applied Sciences, Vol. 4, Issue 5 · 31 May 2007 · 6,817 accessesView PDFCite
Research ArticleOpen accessIn the abstractData Quality and IndicatorsJorge Matute, A.P. GuptaThis study highlights the importance of collecting good quality data from multidisciplinary studies. Bias in data may be the result of instrument inaccuracies, imprecise data recording techniques, inaccurate data entry to computers or inappropriate statistical analysis and presentation. Recommendations for good data quality control are given. Different types of data are discussed: raw data, simple indicators and complex indicators. It … …American Journal of Agricultural and Biological Sciences, Vol. 2, Issue 1 · 31 Mar 2007 · 7,857 accessesView PDFCite
