Research ArticleOpen accessAll words, across the recordReview of Energy Detection for Spectrum Sensing in Various Channels and its Performance for Cognitive Radio ApplicationsR. Suresh Babu, M. SuganthiSpectrum sensing is the basic and important operation in Cognitive Radio (CR) to find the unused spectrum. Energy detector is a popular sensing method because it doesn’t require transmitted signal properties, channel information, of even the type of modulation. This study summarizes the performance result of energy detector over Additive White Gaussian Noise (AWGN), Rayleigh fading and Nakagami fading channels. … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 2 · 4 Aug 2012 · 7,766 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordEffects of Intraarticular Tramadol Administration on Biochemical and Cytological Properties of Equine Synovial Fluid: Comparison with LidocaineAlireza Raayat Jahromi, Abutorab Tabatabaei Naeini, Saeed NazifiProblem statement: Diagnostic and therapeutic arthroscopic surgeries are procedures performed quite frequently in equine practice; and are considered to cause some degree of postoperative pain. The aim of the present study was to evaluate the equine synovial fluid biochemical and cytological changes following intra-articular administration of tramadol as a potential analgesic. Approach: Six adult healthy donkeys were selected after clinical … …American Journal of Pharmacology and Toxicology, Vol. 6, Issue 1 · 14 Jun 2011 · 7,514 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordSome Properties of Certain Subclass of Meromorphically Multivalent Functions Defined By Linear OperatorF. Ghanim, M. DarusProblem statement: By means of the Hadamard product (or convolution), a linear operator was introduced. This operator was motivated by many authors namely Srivastava, Swaminathan, Owa and many others. The operator was indeed needed to create new ideas in the area of geometric function theory. Approach: The linear operator of meromorphic p-valent functions was proposed and defined. The preliminary concept … …Journal of Mathematics and Statistics, Vol. 6, Issue 1 · 31 Mar 2010 · 7,342 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordConcentration and Physicochemical Properties of Chitosan Derivatives Determine the Induction of Defense Responses in Roots and Leaves of Tobacco (Nicotiana tabacum) PlantsAlejandro B. Falcón-Rodríguez, Juan C. Cabrera, Eduardo Ortega, Miguel Ángel Martínez-TéllezProblem statement: The chitosan derivatives promote diverse defensive responses in plants, which are affected by chitosan chemical features and concentration. Glucanase (EC 3.2.1.6), Phenylalanine Ammonia-Lyase (PAL, EC 4.3.1.5) and peroxidase (POD, EC 1.11.1.6) are key enzymes in tobacco defense responses. Thus, the aim of this study was to know the behavior of their enzymatic activity in leaves and roots of … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 3 · 30 Sep 2009 · 9,263 accessesView PDF Cite
