Extraction and mass transfer study of Cupressus sempervirens L. oil by hydro-distillation method
...Show More Authors

The extraction of Cupressus sempervirens L. or cypress essential oil was studied in this paper. This cypress oil was extracted by using the hydro-distillation method, using a clevenger apparatus. Cupressus sempervirens L. leaves were collected from Hit city in Al-Anbar province – Iraq. The influences of three important parameters on the process of oil extraction; water which used as a solvent to the solid ratio (5:1 and 14:1 (ml solvent/g plant), temperature (30 to 100 °C) and processing time, were examined to obtain the best processing conditions to achieve the maximum yield of the essential oil. Also, the mathematical model was described to calculate the mass transfer coefficient. Therefore, the best conditions, that were obtained in this study, were at 4hr as a reaction time, the temperature of about 100 °C, solvent to solid ratios of 10:1 ml solvent/g plant. The volumetric mass transfer coefficient at ratios 10:1 and 14:1 solvent to solid ratio were 0.017 and 0.007 min−1 respectively. Thus, it took less time to extract the Cupressus Sempervirens L. oil by using the 10:1 compared to using 14:1 solvent to solid ratio. The composition compounds of extracted C. sempervirens L. essential oil was analyzed and identified by Gas Chromatography Mass Spectrometry (GC-MS).

Enhancing the human resources quality by adopting an adventure learning method in their development
...Show More Authors

The research aims to identify how to enhance the quality of the human resources, focusing on four dimensions (efficiency, effectiveness, flexibility, and reliability), by adopting an adventure learning method that combines theoretical and applied aspects at the same time, when developing human resources and is applied using information technology, and that Through its dimensions, which are (cooperation, interaction, communication, and understanding), as the research problem indicated a clear deficiency in the cognitive perception of the mechanism of employing adventure learning dimensions in enhancing human resources quality, so the importance of research was to present treatments and proposals to reduce this problem. To achieve

Extraction, Partial Purification and Characterization of Lipase Enzyme from Different Animal and Plant Sources
...Show More Authors

The study aimed to extract the lipase enzyme from different sources, estimate its enzymatic activity, choose the best sources in terms of enzymatic activity, partially purify, and characterize it. The enzyme was extracted from plant sources (pumpkin seeds, melon seeds, and orange peels). The enzyme extract was precipitated with ammonium sulfate at a saturation level of 80%. The dialysis and lyophilization processes were performed for the partially purified enzyme. The optimum temperature for the partially purified enzyme was 40°C and the optimum pH was 7. The enzyme activity of the plant sources was 2.598, 0.723, and 1.333 units g-1, respectively. Animal sources (chicken pancreas and intestinal tract of carp fish). The enzymatic ac

Extraction, Purification and Characterization of Peroxidase from Pseudomonas aeruginosa and Utility as Antioxidant and Anticancer
...Show More Authors

        Peroxidase is a class of oxidation-reduction reaction enzyme that is useful for accelerating many oxidative reactions that protect cells from the harmful effects of free radicals. Peroxidase is found in many common sources like plants, animals and microbes and have extensive uses in numerous industries such as industrial, medical and food processing. In this study, P. aeruginosa was harvested to utilize and study its peroxidases. P. aeruginosa was isolated from a burn patient, and the isolate was verified as P. aeruginosa using staining techniques, biochemical assay, morphological, and a sensitivity test. The gram stain and biochemical test result show rod pink gram-ne
