Research ArticleOpen accessIn the abstractComparative Evaluation of the Epidural Dexmedetomidine, Ketamine or Fentanyl in Combination with Bupivacaine in DogsEman M. Nour, Mahmoud Mahmoud Othman, Gamal I.A. Karrouf, Adel E.I. ZaghloulCastration is one of the most common procedure. It is a potential source of mild to moderate pain which is enough to induce inflammatory process, necessitate the incorporation of analgesics. This study was designed to evaluate the effect of epidural bupivacaine alone or in association with fentanyl, ketamine or dexmedetomidine on analgesia for the first 24 h post surgical castration. … …American Journal of Animal and Veterinary Sciences, Vol. 8, Issue 4 · 8 Nov 2013 · 7,188 accessesView PDFCite
Research ArticleOpen accessIn the abstractStructural Consequences of the Polymorphism Q223R in the Human Leptin Receptor: A Molecular Dynamics StudyJonathan P. Carrillo-Vázquez, Brenda Chimal-Vega, Beatriz Zamora-López et al.Leptin Receptor (LEPR) is a component of a signaling pathway related to appetite and energy expenditure. Single Nucleotide Polymorphisms (SNP) of Leptin receptor gene (lepr) have been proposed as possible modulator of adipose tissue and body weight. The main phenomenological consequence reported of these SNPs is the modulation of the LEP-LEPR interaction promoting the weight gain. Particularly, Q223R polymorphism has … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 3 · 23 Sep 2013 · 7,835 accessesView PDFCite
Research ArticleOpen accessIn the abstractElectromagnetic Field and Γ Aminobutyric Acid a Receptors Interaction in the Fear ResponseM. Taherianfard, A. Bahaodini, M. Fazeli et al.Freezing behavior is a fearful reaction to specific stimuli, most commonly observed by animals. One of the neurotransmission system most consistently linked with fear response is the GABAergic system, in which GABA through GABAA receptor can influence fear response. The aim of the present investigation was to examine the effect of IP injection of muscimol (GABAA agonist) and bicuculline (GABAA … …Current Research in Psychology, Vol. 4, Issue 1 · 4 Sep 2013 · 7,515 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultichannel Cognitive Cross Layer Optimization for Improved Video TransmissionMeenakshi Murugappan, Manimekalai Thirunavukkarasu, Maneesha S. MohanMultimedia applications particularly real-time video transmission in wireless networks, envisions end to end user perceived video quality as an important QoS parameter to be achieved. Cognitive Radio promising efficient spectrum utilization combined with Cross layer optimization is seen as a powerful combination to achieve the desired video quality. This study proposes Optimal Channel Sensed Multichannel Cognitive MAC (OCSM-CMAC), a QoS … …Journal of Computer Science, Vol. 9, Issue 1 · 6 Feb 2013 · 7,199 accessesView PDFCite
Research ArticleOpen accessIn the abstractPerformance of Energy Detection and Matched Filter Receivers in Human Body Communication ChannelMohamad Abou El-Nasr, Heba Shaban, Mohammed Al-AbyadhThis study studies the Bit-Error-Rate (BER) performance of matched filter and energy detection receivers in Human Body Communication (HBC) channel model. HBC, as defined by the IEEE 802.15 Task Group (TG) 6, is a Body Area Network (BAN) at frequency band 5-50 MHz, where communication is from body surface to body surface. The Bit-Error-Rate (BER) performance is investigated for Energy … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 5 Jan 2013 · 6,694 accessesView PDFCite
Research ArticleOpen accessIn the abstractGenetic Based Plus Integral Controller for PMBLDC Motor Control using Resonant Pole InverterMuruganantham, PalaniPermanent Magnet Brushless DC (PMBLDC) motor drives are increasingly popular in industrial applications due to rapid progress of technologies in power electronics and the growing demand for energy saving. The increasing demand of energy saving from society is the external force for the development of PMBLDC motor drives. It is however driven by a hard-switching Pulse Width Modulation (PWM) inverter, … …American Journal of Applied Sciences, Vol. 9, Issue 12 · 5 Jan 2013 · 8,146 accessesView PDFCite
Research ArticleOpen accessIn the abstractγAminobutyrate B Receptors in Central Amygdaloid and Medial Amygdaloid Nuclei of Amygdala Modulate Aggression in Male RatsMahnaz Taherianfard, Zahed Abdolahi, Hamid Rajaian et al.One neurochemical system most consistently linked with aggression is the GABAergic system. The aim of the present investigation was to examine the effect of injection of baclofen (GABAB agonist) and CGP35348 (GABAB antagonist) in the Central Amygdaloid (CA) and Medial Amygdaloid (MA) nuclei of the amygdala on offensive aggression behavior in the animal model. Sixty six adult male rats weighing … …Neuroscience International, Vol. 3, Issue 1 · 3 Sep 2012 · 7,257 accessesView PDFCite
Research ArticleOpen accessIn the abstractReview 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 PDFCite
Research ArticleOpen accessIn the abstractA Cross Layer Frame Work for Enhanced Quality of Service Provisioning in Worldwide Interoperability for Microwave Access NetworksS.J.K. Jagadeesh Kumar, T. PurusothamanProblem statement: The demand for multimedia applications in WiMAX networks is growing at a rapid pace. A method for guaranteeing Quality of Service (QoS) for different classes of traffic is therefore gaining importance.
