Research ArticleOpen accessEvery word in the titleEcological Studies of Epiphytic Microalgae and Epiphytic Zooplankton on Seaweeds of the Eastern Harbor, Alexandria, EgyptN. G. Shams El-Din, N. A. Shaltout, M. Z. Nassar, A. SolimanA qualitative and quantitative study on the epiphytic microalgae and epiphytic zooplankton were conducted in order to follow up their community structures on seaweeds in relation to some physico-chemical variables in the coastal waters of the Eastern Harbor of Alexandria. Water and macroalgal samples were collected seasonally during two years successively: Winter, summer, autumn (2012) and spring (2013). The collected … …American Journal of Environmental Sciences, Vol. 11, Issue 6 · 9 Dec 2015 · 7,587 accessesView PDF Cite

Research ArticleOpen accessIn the author namesDietary Management Strategies to Mitigate Decreased Feed Intake Associated with Terminal Implant Administration in Finishing Beef SteersAlexandria Kelly, Warren Rusche, Forest Francis et al.Re-implanting with a terminal implant often reduces subsequent dry matter intake (DMI). Crossbred steers (n = 27, initial body weight = 385 ± 30.8 kg) were used to assess the effects of locomotion immediately after terminal implantation and increased forage inclusion 7-d post-implantation on feed and water intake, rumination, and activity. Steers were implanted with 100 mg trenbolone acetate and … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 4 · 30 Oct 2024 · 4,854 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPresents Some Aspects and Applications of Projective GeometryRelly Victoria Virgil PetrescuProjective geometry is that area of geometry that treats geometric figures from the point of view of the perspective and the horizon line, figures that are considered invariable by projection. The origins are found in the Pappus works of Alexandria (4th century AD), which, referring to the results of Apollonius in Perga, introduces the concept of an anarchic report. The … …Journal of Mechatronics and Robotics, Vol. 3, Issue 1 · 10 Jul 2019 · 11,799 accessesView PDF Cite

Research ArticleOpen accessIn the abstractAnaerobic Digestion of Pulping Wastewater Using Up-flow Anaerobic Sludge Blanket (UASB) Reactor at Mesophilic ConditionRanda M. Osman, M. HamadThe waste considered for this study was the effluent of the pulping process produced during the manufacture of pulp and paper in the Rakta integrated pulp and paper mill in Alexandria. The pulping process in Rakta mill is conducted under pressure of 7-8 bar, 165°C using 10% NaOH based on straw weight for 2 h. The spent liquor after alkali … …OnLine Journal of Biological Sciences, Vol. 15, Issue 3 · 11 Aug 2015 · 6,927 accessesView PDF Cite

Research ArticleOpen accessIn the abstractA Dynamic Voltage Restorer for Voltage Sag Mitigation in a Refinery with Induction Motors LoadsTarek I. El-Shennawy, Abdel-Mon’em Moussa, Mahmoud A. El-Gammal, Amr Y. Abou-GhazalaProblem statement: ANRPC is a refinery based in Alexandria, Egypt. The plant was subjected to several shutdowns due to tripping of large induction motors, either by under voltage or by over current relays, sometimes by the mechanical protection. The main cause for such unplanned shutdowns was voltage sags. The Dynamic Voltage Restorer (DVR) has recently been introduced to protect the … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,922 accessesView PDF Cite

Research ArticleOpen accessIn the abstractRETRACTED: On the New Branch of Mathematical ScienceM. Sivasubramanian, S. KalimuthuThe origin of geometry dates back 30000(Thirty thousand years) B.C[3]. Euclid of Alexandria (2300 B.C.) complied the Elements which is the first scientific text book. Euclid assumed five postulates. There is no proof for the fifth postulate. Almost all the celebrated mathematicians tried their best to deduce this from the first four postulates. But unfortunately, nobody was successful. Saccheri and … …Journal of Mathematics and Statistics, Vol. 4, Issue 2 · 30 Jun 2008 · 7,893 accessesView PDF Cite
