Research ArticleOpen accessIn the abstractNeurophysiological Mechanisms of Rapidity Quality Development in Female Students Going in for Basketball and Volleyball at Sports ClubsAngelina Shakhanova, Aida Cheuzheva, Ekaterina Kalnaya, Tatiana PetrovaUsing the “NS-Pshykho Test” certified software package (Ivanovo, Russia), we studied the measurements of Simple Hand-Eye Response time (SHER), tapping test frequency, time of Reaction To Moving Object (RMO), Critical Flicker Fusion Frequency (CFFF) in female students going and not going in for sports (volleyball, basketball) at sports clubs. The basis of neuromotor state is formed by variants of classical … …American Journal of Applied Sciences, Vol. 13, Issue 5 · 17 May 2016 · 7,603 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Association of HLA Class II Alleles with the Response to Alfa-Interferon/Ribavirin Therapy in Chronic Hepatitis C PatientsAwny Aly Abol-Ez Gawish, Nahla Abd El-Hamid Mohammed, Rasha Adel Sayed Ahmed Hussein, Elsaid Galal El-BadrawyHuman Leucocyte Antigens (HLA) class II appears to play an important role in the individual’s immune response to viral infection. The present study was aimed at assessment of the relationship between HLA DRB1 alleles and the response to HCV combined therapy in Chronic Hepatitis C patients (CHC). We enrolled a total of 44 chronically infected HCV patients without Hepatitis B … …American Journal of Immunology, Vol. 11, Issue 3 · 12 Nov 2015 · 6,700 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Modulation Technique for 5G Mobile Communication SystemArun Kumar, Manisha GuptaBy the year 2020, the data traffic can be approximately increase by 30%, which cannot support by existing mobile technologies. Hence, there is a requirement of next generation wireless communication (5G) which aim to provide a high capacity, data-rate at the speed of 1Tbps. By selecting a better modulation technology, the required capacity and data-rate can be achieved. In this … …American Journal of Applied Sciences, Vol. 12, Issue 9 · 28 Sep 2015 · 7,652 accessesView PDFCite
Research ArticleOpen accessIn the abstractDigital High-Pass Filters with Milder High-Pass Effect on Digital ImagesIssa A. Al-ShakhrahImage filtering consists of modifying the original image by logically "reimaging" it with a mathematical imaging device in which spatial response can be controlled by the user. Image filtering is performed by a mathematical operation called convolution, which is simply the successive replacement of each point in the original image by a new value produced by a weighted combination of … …American Journal of Engineering and Applied Sciences, Vol. 8, Issue 3 · 11 Jun 2015 · 7,950 accessesView PDFCite
EditorialOpen accessIn the abstractImpact of Quantitative Pharmacology on Drug DevelopmentAna Ruiz-Garcia, Kourosh ParivarThesuccess of drug development rests over two well defined pillars, a goodunderstanding of the drug’s clinical pharmacology and the appropriate targetpopulation for whom the clinical use is intended. The label for human prescription drugsrequires a good understanding of the pharmacological effects (pharmacodynamicsor PD) and the mechanism of action of the drug as well as detailed informationof the drug’s Pharmacokinetics (PK): … …American Journal of Pharmacology and Toxicology, Vol. 9, Issue 4 · 24 Apr 2015 · 7,158 accessesView PDFCite
Research ArticleOpen accessIn the abstractInteraction of γ Aminobutyric Acid B Receptors and Electromagnetic Field in the Fear ResponseM. Taherianfard, A. Bahaodini, M. Fazeli, S. Karimi HaghighiOne of the most neurotransmission system consistently linked with fear response is GABAergic system. GABA through GABAB receptor can influence fear response. The aim of the present investigation was to examine the effect of IP injection of baclofen (GABAB agonist) and CGP35348 (GABAB antagonist) along with EMF exposure on frequency of fear response. Fifty adult male rats weighing 180-200 g … …Neuroscience International, Vol. 4, Issue 2 · 1 Apr 2014 · 6,691 accessesView PDFCite
Research ArticleOpen accessIn the abstractNEURO FUZZY BASED PERFORMANCE ANALYSIS OF MULTIBAND ULTRA WIDE BAND ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING SYSTEMG. Joselin Retna Kumar, K. S. ShajiThis study proposes an efficient channel-estimation scheme for Multiband (MB) Orthogonal Frequency Division Multiplexing (OFDM)-based Ultra Wide Band (UWB) communication systems. One of the challenges in wireless system is the frequency selective fading caused due to multipath channel between the transmitter and receiver. The signal bandwidth in broad band cellular wireless systems typically exceeds the coherence bandwidth of the multipath … …Journal of Computer Science, Vol. 10, Issue 8 · 5 Mar 2014 · 6,616 accessesView PDFCite
Research ArticleOpen accessIn the abstractMOLECULAR CHARACTERIZATION AND IMMUNOPROTECTIVE ACTIVITY OF CAPSULAR POLYSACCHARIDE OF KLEBSIELLA PNEUMONIAE ISOLATED FROM FARM ANIMALS AT TAIF GOVERNORATEAhmed M.A. Mansour, Hoda M. Zaki, Nibal A. Hassan, Abdulrahman A. Al-HumianyKlebsiella pneumoniae is a Gram-negative enterobacterium that has historically been and currently remains, a significant cause of human disease and several kinds of infections in animals. In the present work, trials for the isolation of Klebsiella pneumoniae from diseased and apparently healthy farm animals (cows, sheep, goats and camels) were done for recognition of Klebsiella pneumoniae subspecies. It was noticed … …American Journal of Infectious Diseases, Vol. 10, Issue 1 · 6 Jan 2014 · 7,937 accessesView PDFCite
Research ArticleOpen accessIn the abstractA Novel Channel Estimation Technique for Complexity Reduction of Least Minimum Mean Square ErrorHany Mohamed El-Ansary, Hussein Ghouz, Ashraf Mamdouh Aziz, Gamal MabroukChannel estimation technique is to predict the frequency response of the radio channel using pilot signal. Channel estimation technique is important part of LTE receiver design. Such technique is used to recover the transmitted signal correctly and to know how the channel conditions are changed over frequency and time. Each channel estimator has a specified complexity computed according to its … …American Journal of Applied Sciences, Vol. 10, Issue 10 · 5 Sep 2013 · 6,999 accessesView PDFCite
Research ArticleOpen accessIn the abstractEmbedded Computer Based Active Vibration Control System for Vibration Reduction of Flexible StructuresVenkata Ratnam Tatavolu, Seetha Ramaiah PanchumarthyResearch on Active Vibration Control System (AVCS) is being carried out to reduce structural vibrations caused by unwanted vibrations in many application areas such as in space, aircraft structures, satellites, automobiles and civil structures (bridges), particularly at low frequencies.
