Research ArticleOpen accessEvery word in the titleStudy of the Drying Kinetics of Lemon GrassMustafa Ibrahim, K. Sopian, W. R.W. DaudProblem statement: The thin- layer drying experiments were conducted to examine the effect of drying air temperature and humidity on the drying kinetics. Approach: A model to estimate the drying behavior of Lemon grass was developed). Results: Four different thin-layer drying models were compared with respect to their coefficient of determination (R2), Mean Bias Error (MBE) and Root Mean Square … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,432 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleComparison and Parametric Study of Flameless Oxidation in a Gas Turbine Using Two Kinetics MechanismsMohamed Hamdi, Hmaïed Benticha, Mohamed SassiThe so-called "Flameless Oxidation" is a novel combustion mode, in which combustion products are re-circulated and mixed into the fresh incoming fuel and air streams. This reduces the concentration of the reactants and thereby reducing the reaction rate through avoiding the formation of sharp high temperature zones in the combustion chamber. Flameless combustion has been acknowledged as one of the … …American Journal of Environmental Sciences, Vol. 4, Issue 5 · 31 Oct 2008 · 6,950 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleA Method for Transmitting Spacecrafts in Space with Velocity of at Least 0.01 of the Light Speed Using Materials with Very High Kinetic Energy in High Electric FieldsMario Nady AiadMany space new missions are on calendar this decade for Moon, Mars and other planets. Some of these missions are depending on simple reliable chemical thrusters and others on the nonchemical advanced propulsion techniques. In most of nonchemical techniques a nuclear source of energy is necessary as in nuclear electric rockets where the maximum velocity produced is around 20 km/s. … …American Journal of Engineering and Applied Sciences, Vol. 16, Issue 4 · 22 Dec 2023 · 5,365 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDetermination of Kinetic Parameters of a Super Heavy Chisel Plow Under Various Operating ConditionsS. A. Al-Suhaibani, A. Al-Janobi, A. E. GhalyProblem statement: Tillage is a process of creating a desirable soil condition for seed germination and growth. The tillage of soil is considered to be one of the biggest farm operations as the tillage operation requires the most energy on the farm. Chisel plow is widely used by farmers as a primary tillage tool. Performance data for chisel plow operation … …American Journal of Applied Sciences, Vol. 7, Issue 8 · 31 Aug 2010 · 7,652 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleKinetic Study of the Effect of Selected Surfactants on Corrosion of CopperHowaida M. El-KashlanThe rates of copper corrosion were determined by measuring the limiting current of anodic dissolution of copper in phosphoric acid in presence and in absence of cetyl trimethyl ammonium bromide (CTAB) and cetyl pyridinium bromide (CPYB). The rate of corrosion is found to decrease by increasing the concentration of the surfactant. The percentage of inhibition ranged from 1.85 to 33.97% … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,137 accessesView PDFCite
Research ArticleOpen accessEvery word in the titlePlants Responses to Nutrients Follow the Saturation Kinetic Typical of Enzyme Systems: Biological, Economical and Environmental ImplicationsR.P. LanaAgricultural efficiency has been associated with high plant productivity. However, it is dependent on fertilizers, which are nonrenewable resources. Crop production response to fertilizers is hyperbolic, following the Michaelis-Menten model and the law of diminishing return. Data of crop production (barley, bean, corn, cotton, soybean and wheat) as a function of nitrogen, phosphorus, and potassium fertilization were analyzed by Lineweaver-Burk … …OnLine Journal of Biological Sciences, Vol. 8, Issue 1 · 31 Mar 2008 · 6,895 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptical Properties and Kinetic Behavior of Chlorine in Pure Water and Swimming Pool Water using Surface Plasmon Resonance TechniqueW.Y.W. Yusmawati, W. Mahmood Mat YunusAn optical sensor based on surface plasmon resonance phenomenon for detection of chlorine in pure water and swimming pool water is presented. The measurement was carried out at room temperature using Kretschmann surface plasmon resonance technique. When the air medium outside the metal film is changed to chlorine solution, the resonance angle shifted to the higher value. The shift of … …American Journal of Applied Sciences, Vol. 4, Issue 12 · 31 Dec 2007 · 7,363 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleInfluence of Supplementary Bioavailable Carbon on the Thermal and Biological Kinetic Parameters of the Composting Process of Tomato Plant TrimmingsA.E. Ghaly, F. AlkoaikThree laboratory-scale bioreactors were used to investigate the influence of bioavailable carbon addition on the composting process of tomato remains. Sugar, cheese whey and used cooking oil were used as bioavailable carbon sources. The amounts of materials added to the compost mixture had equal energy contents. The initial moisture contents and C: N ratios of the compost mixtures were maintained … …American Journal of Environmental Sciences, Vol. 2, Issue 1 · 31 Mar 2006 · 6,563 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleOptimalization of the Swim-Up Method for Bali Bull Sperm: Effect of Incubation Time and Medium on Sperm KineticsAthhar Manabi Diansyah, Muhammad Yusuf, Rahmat et al.Bali bulls (Bos javanicus) are an essential part of Indonesia’s indigenous livestock, prized for their ability to thrive in challenging environments, their natural disease resistance, and their strong reproductive capabilities. The aim of this study was to refine the swim-up technique for preparing Bali cattle sperm. We evaluated the effects of two commonly used media Tyrode's Albumin Lactate Pyruvate (TALP) … …American Journal of Animal and Veterinary Sciences, Vol. 20, Issue 4 · 9 Feb 2026 · 1,687 accessesView PDFCite
