  • Microbial deterioration of a 13 AH-century manuscript housed in Al-Azhar library in Egypt: A case study
  •     Noura Sh. A. Hagaggi, Taha Ayman Salah

    This paper focused on studying the bacterial and fungal infections attacked the manuscript that dated back to 1251 AH at Al-Azhar library in Cairo, Egypt. Based on the partial 16S rRNA gene sequence, the isolated bacteria were Acinetobacter indicus and Exiguobacterium aurantiacum. Two fungal colonies which belonged to the genera Stachybotrys chartarum and Aspergillus flavus were also isolated. The antibacterial and antifungal activities of Acacia....

  •     Ahmed Mohsen, , Dr.Mohammed Mostafa, Dr. Mohammed Mohammed Fawzy, Dr. Talaat Salah El-Din Ahmed, Dr. Amany Yaiha Shahine

    Radioactive materials concentration of four studied waste samples resulted from Phosphoric acid purification project and ore products project were measured using gamma ray spectrometry (high purity germanium-HPGe detector). These concentrations were measured for U- 238 in range of (471.6-5.8×103) Bq/kg [(38.02-469.6) ppm] , Th-232 ranged between (34-1.33×103) Bq/kg [(8.4-326.9)ppm] Ra-226 ( 227-8346) Bq/kg [(18.4-699.1) ppm] and K-40....


  • Application and Evaluation of DSSAT V.4.6.1 Program for Simulation of Wheat and Soybean yields in Egypt
  •     Abou El –Enin, M.M, Abo-Remaila S. I. and Mahmoud, A.S

    Adoption of conservation agriculture (CA) is increasingly being promoted as a way of adapting agricultural systems to increasing climate variability, especially for areas such as Africa where rainfall is projected to decrease. The DSSAT (Decision Support System for Agro Technology) crop simulation models can be a valuable tool in evaluating the effects of CA, which are viable both economically and environmentally. Our objectives were to evaluate....


  • Effect of applying Potassumage and Banana ash combination as bio fertilizers on productivity of the Egyptian wheat
  •     Abo-Remaila S.I, Abou El Enin, MM

    Two pot experiments and field experiment were carried out at Agric. Res. Station, Fac. Agric., Al-Azhar Univ. Nasr City and El-Aleg region, Kaliobia governorate, Egypt, during 2011/2012, 2012/2013 and 2013/2014 to investigate the influence of K fertilizer packages as bio fertilizer on the productivity of wheat varieties. The three studied K fertilizer packages treatments were Potassiumag (bio fertilizer), Banana ash 4%, Potassumage +Banana ach 4%....
