This thesis touched upon the effect of iron doping on the structural, morphological, compositional, optical and dielectric properties of bismuth oxide thin films. Bismuth oxide thin films with a thickness of 0.50 μm were deposited by thermal evaporation of bismuth oxide powders on glass substrates under a vacuum pressure of approximately 4-10 mbar. This was followed by doping the films with iron by mixing the iron nano-powders with the bismuth oxide powders before evaporation. The researcher used three increasing amounts of iron for this purpose.

This study aimed to examine the effectiveness of a structured educational program on patient knowledge and practice regarding colostomy care in the West Bank. The researcher used a quasi-experimental study design (pre-test and post-test) to achieve the objectives of the study. The sample consisted of 37 adult male and female patients, who had a colostomy operation, as a non-probability convenience sample for this study. The samples were taken in surgical and medical outpatient clinics and oncology clinics in governmental and private hospitals in the West Bank.
