  • The Perception of the Role of Post-Lesson Discussion in the Professional Development of Omani English Teachers
  •     Waleed Salim Amer Al-Harthy,

    This study aims to investigate the perceptions of Omani senior English teachers and teachers towards the role of post-lesson discussion in developing teachers. The study findings illustrated that both SETs and teachers hold a positive attitude towards the importance of feedback in developing effective teachers and that cooperation governs the relationship between them during feedback sessions. Also teachers play an active role in the lesson....


  • Decolorization and degradation of sunset yellow in aqueous solutions by advanced Fenton oxidation
  •     Gamal O. El-Sayed, Said M. Teleb, Heba M. Gouda

    Decolorization of sunset yellow dye (SY) in an aqueous solution was investigated by Fenton reaction using H2O2/Fe2+ system. Different parameters controlling the degradation efficiency as pH and H2O2 and Fe2+ concentrations were evaluated. The optimal operational conditions were found to be [Fe2+] = 2.55x10-3 mmol, [H2O2] = 0.2425 mmol at pH 2.7. The study of the Kinetics of decolorization indicated that the degradation kinetics of SY followed....


  • Molecular Identification of Strawberry Latent Ring Spot Virus (SLRSV) In Egypt
  •     Sh. I. EL-Morsy, M. A. EL-Sheikh*, R.A. Abd El-Razik*, Sahar A.Youssef**, and A.A. Shalaby**

    Strawberry latent ringspot virus (SLRSV) isolated from symptoms and symptomless strawberry plants and identified with a specific antiserum using Double Antibody Sandwich ELISA (DAS-ELISA). Survey was conducted through three successive seasons during 2013-20l6 on commercial strawberry fields in four governorates in Egypt. The percentages of infection which recorded from the survey were 7.5, 6.3, 5.9% (Al-Dair-region) and 9.4, 10.6, 10.5% (Kafer....

  •     Waleed Salim Amer Al-Harthy,

    The current study aims to determine the best principles and practices of educational management among the private colleges in Muscat City, Sultanate of Oman. To achieve that, the study examines the influence of teamwork, organizational culture, nature of leadership, professional development, motivations and innovations on college improvements. The SEM analysis results indicated that that the research variables such as Organizational Culture,....


  • Response of Wheat Yield to Irrigation Scheduling Program under Egyptian Sandy Soil Conditions
  •     M. M. Abou El –Enin ,

    Two field experiments were performed in EL-Busily region, EL-Behira governorate under the condition of sandy soil during 2009/2010 and 2010/2011 seasons, to study the impact of three amount of water irrigation (60, 70 and 90% from evapotranspiration rate (1216 m3) and three compost rates (2, 4 and 6 ton/fed.) on some growth, yield and its components of two wheat varieties (sakha 93 and Gemmieza 9). In both of seasons, the treatments were....


  • Cu (II), Mn (II) and Zn (II) Adsorption with Modified Grafted Cellulose from Aqueous Solution
  •     Alaa M.M. EL-Torky, Gamal O. El-Sayed, Enas E.Abd-Elmonem

    Cellulose powder where modified by grafting with acrylamide to improve the swelling characters. The conditions of grafting such as monomer concentration, initiator ratio, time of grafting and grafting temperature were evaluated. The grafting efficiency, The swelling characters as water retention values and sodium binding capacity were determined and nitrogen content were also evaluated for grafting cellulose powder The structure of these....


  • Synthesis and Inhibition Effect of Two New Fatty Amido-Cationic Surfactants on Carbon Steel Corrosion in 1 M HCl Solution
  •     A. Y. EL- Etre, Wagdy I. El-Dougdoug, Salah Eid and Ahmed N. El-Din

    Two new cationic surface-active compounds namely; N,N-dimethyl-N-(3-tetradecanoamidopropyl)-1-ammonium bromide and N,N-dimethyl-N-(3-hexadecanoamidopropyl)-1-ammonium bromide referred as (ACS3.1 and ACS3.2), respectively were synthesized and their chemical structures confirmed by spectra tools (FT-IR and 1H-NMR). The inhibition effect of the synthesized cationic surfactants on carbon steel in 1 M HCl solution was evaluated using weight loss and....


  • Antibacterial activity of Cu@Ag nanocomposites against water bacterial pollution
  •     Ahmed M. Azzam, Mahmoud M. Hazaa, Ashraf M. El Saeed and Mai A. Abdel-Naem

    Nanomaterials have a great potential in purifying water and wastewater treatment due to their tremendous antibacterial activity. In the present study, Cu@Ag nanocomposite (NC) was synthesized and characterized using scanning electron microscopy (SEM) and transmission electron microscope. The antibacterial activity of Cu@Ag NC was tested against water Gram-positive bacteria (Staphylococcus sp.) and Gram-negative one (Escherichia coli) using well....


  • Antibacterial activity of cupric oxide nanoparticles against pathogenic bacteria
  •     Ahmed M. Azzam, Mahmoud M. Hazaa, Ashraf M. El Saeed and Marwa R. Hamed

    Nano materials have a wide range of applications due to their interesting size-dependent chemical and physical properties compared to particles of size in the range of micrometer. In this study, we studied the structural and antimicrobial properties of cupric oxide nanoparticles (CuO NPs) that synthesized by the sol–gel method and characterized by using scanning electron microscopy (SEM) and transmission electron microscopy (TEM).....


  • Synthesis of nonionic polymeric surfactants with amide oxime terminal groups
  •     A. M. F. Eissa, M. A. Radwan, M. M. Azab, M. El Hefnawy, M. M. Deef Allah

    Nonionic polymeric surfactants were prepared by formation of polymer from reaction of allyl alcohol with acrylonitrile. Then product reacted with different fatty acids (Capric, myrestic and stearic) inorder to obtain half ester polymer. Then propylene oxide was added directly to polymer (5, 10, 15 and 20 mole), in the presence of KOH as catalyst, then nitrile group in polymer react with hydroxyl amine in the presence of NaOH to obtain amide oxime....
