Research ArticleOpen accessIn the abstractMeasuring Multi-Ethnic Students Citizenship Competence: Domains and IndicatorsMohd Mahzan Awang, Alfitri, Abdul Razaq Ahmad, Norila La UluThe current study aims at developing and validating an instrument to measure citizenship competences among multi-ethnic students. It was developed based on the Iceberg Competency Model (McBer, 1996) and citizenship competence from the works of (Ten Dam and Volman, 2007; Ten Dam et al., 2010; 2011). The Citizenship Competences Framework was developed prior to indicators/items development. The Framework contained four … …American Journal of Applied Sciences, Vol. 13, Issue 1 · 1 Feb 2016 · 7,579 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemediation of Feedlot Nutrients Runoff by Electrocoagulation ProcessArjun Thapa, Shafiqur Rahman, Md. Saidul BorhanNutrient runoff from Concentrated Animal Feeding Operations (CAFOs) may cause ground and surface water pollution. Scientists and researchers are continually searching for appropriate technologies to mitigate feedlot nutrient runoff pollution. In this study, suitability of electrocoagulation treatment process was examined under laboratory conditions to mitigate nutrient pollutants from the feedlot runoff. Feedlot runoff was treated with three different type of … …American Journal of Environmental Sciences, Vol. 11, Issue 5 · 9 Nov 2015 · 7,087 accessesView PDFCite
Research ArticleOpen accessIn the abstractScorpius: sFlow Network Anomaly SimulatorMarcos V.O. de Assis, Mario Lemes Proença Jr.Due to the increasing amount of data traveling computer networks every day, efficient management of this information is required to ensure the quality of the services provided by them. Development of new network management tools and mechanisms is a widely approached area due to its importance, not only to the current technology, but also to next generation network standards and … …Journal of Computer Science, Vol. 11, Issue 4 · 23 Jul 2015 · 7,534 accessesView PDFCite
Research ArticleOpen accessIn the abstractMultiple-Input Multiple-Output Transmission Over a Multipath Faded ChannelsI.A.Z. QatawnehThe use of multiple antennas at the transmitter as well as at the receiver can greatly improve the capacity of a wireless link when operating in a rich scattering environment. In such an arrangement all transmitting antennas radiate in the same frequency band so the overall spectral efficiency becomes very high. Such a multiple antenna scheme, popularly known as Multiple … …American Journal of Applied Sciences, Vol. 10, Issue 3 · 11 Mar 2013 · 6,420 accessesView PDFCite
Research ArticleOpen accessIn the abstractAn Efficient Prediction of Missing Itemset in Shopping CartV. Palanisamy, M. NirmalaMany researches has focused mainly on how to expedite the search for frequently co-occurring groups of items in &#34shopping cart&#34 and less attention has been paid to the methods that exploit these &#34frequent itemsets&#34 for prediction purposes. This study contributes to this task by proposing a technique that uses the partial information about the contents of a shopping cart for … …Journal of Computer Science, Vol. 9, Issue 1 · 8 Feb 2013 · 7,044 accessesView PDFCite
Research ArticleOpen accessIn the abstractMoringa Oleifera Leaves Extract Attenuates Male Sexual DysfunctionWipawee Thukhammee, Supaporn Muchimapura, Sitthichai Iamsa-ard et al.Problem statement: At present, the novel agent that is effective, cheap and easy to approach for treating male sexual dysfunction is required due to the current poor therapeutic efficacy. Though Moringa oleifera is reputed for aphrodisiac activity in traditional folklore, no scientific evidence is available. Therefore, we aimed to determine the effect of M.oleifera leaves extract on male sexual behaviors … …Neuroscience International, Vol. 3, Issue 1 · 1 Sep 2012 · 32,907 accessesView PDFCite
Research ArticleOpen accessIn the abstractGeneral Circulation in the Malacca Strait and Andaman Sea: A Numerical Model StudySyamsul Rizal, Peter Damm, Mulyadi A. Wahid et al.In the Andaman Sea and Malacca Strait, as in other parts of the Indian Ocean, the seasonal change of the wind plays a most important role: the south-west (hereafter SW) is monsoon active from June through September and the north-east (hereafter NE) monsoon is active from December through February. During the NE monsoon the winds are directed from the north … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 11 Aug 2012 · 18,578 accessesView PDFCite
Research ArticleOpen accessIn the abstractNeuroprotective Effect against Cerebral Ischemia of Passiflora foetidaJintanaporn Wattanathorn, Natcha Sattroopinat, Terdthai Tong-Un et al.Problem statement: Although cerebral ischemia induced by stroke has been regarded as the important problem worldwide, the therapeutic efficacy is still inadequate. Since the free radicals are implicated in the pathophysiology of cerebral ischemia, the prophylactic protection against stroke with neuroprotective agent possessing antioxidant effect has gained much attention. Therefore, this study was designed to determine whether the alcoholic extract … …American Journal of Applied Sciences, Vol. 9, Issue 4 · 16 Feb 2012 · 8,245 accessesView PDFCite
Research ArticleOpen accessIn the abstractCritical Retrospect on Conventional and Luminescent Solar Concentration DevicesHamzah Abdul-Rahman, Chen WangProblem statement: Conventional solar concentrators are only sensitive for the beam radiation and they function poorly in overcast sky conditions. Even under a clear sky condition, trackers are always needed for conventional solar concentrators. Static concentrators always come with a poor concentration rate without a tracker and the light concentrated by normal Luminescent Solar Concentrators (LSC) could not be transported … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 6,930 accessesView PDFCite
