Pages: 1 – 8 Mehdi Salih Shihab Abstract: A theoretical study on stable geometries of a nematic liquid crystal (LC) molecule (4-methoxybenzylidene-4′-n-butylaniline (MBBA)) assembled on the carbon nanosolid (CNS) surface models (graphite sheet and carbon nanotube (CNT): zigzag, armchair) has been carried out by using semi-empirical molecular quantum calculations within the parameterized model number 3method

Pages: 9 – 15 Nadia Altaee, Ayad Fahdil, Kumar Sudesh and Emad Yousif Abstract: In the present study, the ability of Rhodococcus equi for polyhydroxyalkanoates (PHA) production was closely observed in the presence of crude palm kernel oil as a carbon source. Gas chromatography analysis proved that the biopolymer was a homopolymer that comprised of 38%

Pages: 17 – 27 Hossam Altaher, Tarek E. Khalil and Reda Abubeah Abstract: In general, the production of potable water from raw water sources involves the coagulation or flocculation process to remove turbidity. Alum has been widely used as a coagulant; however, there is a concern about its associated risk of Alzheimer’s disease. As a result,

Pages: 29 – 42 Hossam Altaher, Fahd M. AL-Oufi, Yehia H. Magdy and Manar Hassan Abstract: Dates pits, a widely available agricultural waste, was used to produce two samples of activated carbon. The first sample was prepared by thermal treatment at 500 °C for two hours, and the other one was prepared through microwave irradiation for

Pages: 43 – 50 Mohmd Sarireh Abstract: The Tafila area (Jabal Al Hala) is covered with volcanic tuff, which has been tested and studied for its possible use as a construction material in the production of ordinary concrete. The volcanic tuff material was used at 10, 20, 30, 40, and 50% mix proportion of the

Pages: 51 – 59 Muhammad Yasir Amir Khan and Vali Uddin Abbas Abstract: Wheeled inverted pendulum (WIP) is an underactuated and a highly unstable system. In this paper we have proposed modelling and control of WIP as hybrid automaton based on torque equations rather than Lagrangian method. The model was simulated using Simulink® using Direct Inverse Neural
