Research ArticleOpen accessEvery word in the titleUsing Thermal Infrared Imagery (TIR) for Illustrating the Submarine Groundwater Discharge into the Eastern Shoreline of the Dead Sea-JordanEmad Akawwi, Abdallah Al-Zouabi, Maher Kakish et al.Many of thermal anomalies that are indicator of discharge zones of warmer water were observed along the Dead Sea shoreline at the areas of Zarka Ma’in, Zara and Al-Mujeb. The groundwater discharge locations were mapped along eastern shores of the Dead Sea by using aerial thermal infrared imagery (λ = 8-13 µm). A digital thermal infrared camera was used for … …American Journal of Environmental Sciences, Vol. 4, Issue 6 · 31 Dec 2008 · 7,417 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleAn Investigation of Valve Lift Effect on Air Flow and Coefficient of Discharge of Four Stroke Engines Based on ExperimentAbdul Rahim Ismail, Rosli Abu Bakar, SeminThe coefficient of discharge (CD) is defined as the ratio of actual discharge to ideal discharge. In an engine environment, ideal discharge considers an ideal gas and the process to be free from friction, surface tension, etc. Coefficients of discharge are widely used to monitor the flow efficiency through various engine components and are quite useful in improving the performance … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 7,431 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleEnd Discharge Relationship for Free Overfall Affected by Upstream Bed Roughness and SlopeJaafar S. MaatooqThe experimental program of this paper was restricted to free vertical drop structure at the end of the rectangular channel. The roughness and slope of the bed of approach channel are the aim of this study to show their effects on End Depth Ratio (EDR). Three different roughness from smooth (n = 0.009) to rough (n = 0.019) with four-bed … …American Journal of Engineering and Applied Sciences, Vol. 10, Issue 2 · 5 Jun 2017 · 7,498 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePerformance of Difference Electrode Materials in Electrical Discharge Machining of Tungsten CarbideP. Janmanee, A. MuttamaraProblem statement: Electrical Discharge Machining (EDM) is now a well-established machining option in many industries. Tungsten carbide (WC-Co) is an important tool and die material mainly because of its high hardness, strength, wear resistance and high melting point. Normally, EDM is capable of machining geometrically complex or hard material component, that are precise and difficult to machine. The objective of … …Energy Research Journal, Vol. 1, Issue 2 · 31 Oct 2010 · 8,871 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Process Parameters on Electrical Discharge Machined Job Surface IntegrityA.K.M. Asif Iqbal, Ahsan Ali KhanProblem statement: Electrical Discharge Machining (EDM) is the most widely used non conventional machining process for removing material from workpiece by means of a series of repeated electric discharges. Electrical Discharge milling (ED-milling) is an emerging technology where a cylindrical tool electrode follows a programmed path in order to obtain the desired shape of a part. During machining of metals … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 2 · 30 Jun 2010 · 8,584 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleStudy of Benthic Fauna in the Discharge Lagoon of a Shrimp Farm With Special Emphasis on the PolychaetesLuis Rafael Martínez Córdova, Luis Fernando Enríquez OcañaA study of benthic fauna, with special emphasis on polychaetes, was made in the discharge lagoon of an experimental shrimp farm and a pond of the farm. The discharge lagoon was divided into three sections and stocked with shrimp at low density (6 Pl/m2). Neither formulated feed nor fertilization was used in these sections. The control pond was stocked with … …OnLine Journal of Biological Sciences, Vol. 7, Issue 1 · 31 Dec 2007 · 6,680 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleElectrical Sterilization of Juice by Discharged HV Impulse WaveformHee Kyu LeeIn the sterilization system by using HV impulse waveform, apple juice was sterilized with HV discharged oscillatory decay waveform. The optimal condition of impulse waveform for electrical sterilization has presented the excellent condition at 40kV cmˉ1, 4mH and over. The characteristics of this waveform shows oscillatory decay waveform with multiple pulses. And this impulse waveform was more effective to kill … …American Journal of Applied Sciences, Vol. 3, Issue 10 · 31 Oct 2006 · 7,962 accessesView PDFCite
