^14CO2 Fixation and Translocation of Photoassimilates as Selection Criteria of Egyptian Taro Genotypes

Journal of Integrative Plant Biology 2006年第5期48卷 563-566页

The growth characterlstlcs, different physlological parameters, photosynthetic activity （^14CO2 fixation）, and the translocatlon rate of photoassimllates In different taro （Colocasia esculenta L. Schott） genotypes was studled In order to determlne the posslble use of these parameters as selectlon crlterla for dlfferent wldely used genotypes of taro （Delta No. 9, 15, 20, 21, and balady）. The results obtalned suggest that Delta No. 21 shows the most slgnlflcant increase In all parameters tested compared wlth the control （balady）, followed by Delta No. 9, 15, and 20, respectively. The results show a positive correlation between photosynthetlc actlvlty, translocatlon efflclency, and total yield. The selected clone Delta No. 21 Is recommended for cultlvatlon In the delta reglon of Egypt.

Changes in the sucrose metabolism of Cur-cuma longa *** were studied under treatment with different triazole compounds viz.,triadimefon(TDM)and propiconazole(PCZ).Plants were treated with TDM at 15mg/L and PCZ at 10mg/L separately by soil drenching on 80,110,and 140 days after planting(DAP).The plants were harvested randomly on 90,120,and 150DAP to determine the effect of both the triazoles on sucrose metabolizing enzymes and phenol *** sucrose metabolism was studied by analyzing sucrose metaboliz-ing enzymes like sucrose synthase and sucrose phosphate *** the analyses were assayed in leaves and tubers of both control and treated *** was found that both of the triazole compounds had profound effects on these parameters.

UV/O<sub>3</sub>Preirradiated Cotton Fabric-Containing Chitosan for Effective Removal of Heavy Metals

引用

Materials Sciences and Applications 2014年第10期5卷 698-707页

作者： A. Hebeish Kh. Elnagar M. H. helal M. S. ragab M. F. Shaaban Chemistry Department Faculty of Science Helwan University Cairo Egypt Textile Metrology Laboratory National Institute for Standards (NIS) Giza Egypt Textile Research Division National Research Centre (NRC) Giza Egypt

The present work aims at studying the effect of Ultra-Violet/Ozone (UV/O3) irradiation of cotton fabrics on their interaction with chitosan/citric acid based formulation and, the onset of this on the ability of treated fabrics to remove heavy metal ions from their aqueous solutions. To achieve the goal, the cotton fabrics were preirradiated for 90 minutes using UV/O3 as radiation source. The irradiated and the unirrdadiated cotton fabrics were submitted to finishing formulation consisting essentially of chitosan as a finishing agent and citric acid as crosslinking agent in combination with sodium hypophosphite (SHP) as a catalyst. Finishing formulation containing different concentrations of chitosan (0 - 4) along with citric acid (8 g/l) and SHP (4 g/l) were used and the interaction of chitosan with the cotton fabric was assessed through nitrogen measurement. The preirradiated and chemically finished fabrics vis-à-vis the unirrdadiated fabrics were examined for metal ion removal. Results conclude that the preirradiated cotton fabrics exhibit higher nitrogen content than the unirrdadiated fabrics. The same holds true for heavy metal removal, exemplified by Zn2+ and Cd2+ ions from their aqueous solutions. That is, preirradiated fabrics containing chitosan display higher percent heavy metal removal than their unirrdadiated mates.

Examination and Conservation of helal El-Beah Mosque, Dakahlia, Egypt

引用

Journal of Building Construction and Planning Research 2016年第2期4卷 103-118页

作者： Nabil A. Bader ragab Abu El- Hassan Conservation Department Faculty of Archaeology South Valley University Qena Egypt Misr University for Science & Technology (MUS) Conservation Department Giza Egypt

helal El-Beah mosque in Egypt was built from many different materials as sandstone, bricks and marble. These building materials were in a bad condition due to many degradation factors, mainly ground water and salt weathering, so many deterioration phenomena were appeared as horizontal and vertical cracks, salts, loss of the Islamic decorations in the fa?ade and mihrab (Prayer niche), detachment of the plaster, biological colonization and featured dark of the stone surface. Prior to the conservation intervention, the building materials were characterized to identify their components. Scientific conservation treatment was carried out for the long-term conservation of the mosque. Conservation operations at the mosque included: repairing and roof insulation, wet and dry cleaning, joining of cracked parts and surface consolidating, replacement of the Portland cement plaster with lime plaster, re-cladding the lower part of the interior brick walls with sandstone tiles, replacement and completion of the stone blocks.
