The conducted study compares the phytochemical and the antimicrobial potential of four varieties of Brassica napus seed oils. The plant seeds were cultivated during the winter growing season. Soxhlet extractor and Gas Chromatography-Mass Spectrometer (GC-MS) were used for essential oil analysis. The micro broth dilution
assay was applied to test the antimicrobial potential (MIC: Minimum inhibitory concentration, MBC: Minimum bactericidal concentration) of the extracted essential oils against different bacterial strains. A total of 56 phytochemicals were found, including 23 and 25 compounds in the oils of Pactol and Rapifera seed varieties,
respectively, and 21 compounds in each of Bacara and Rally seed oils. Oleic acid constituted about 35.79 %, 15.62%, 7%, and 2.41 % for Rally, Bacara, Rapifera, and Pactol seed oils, respectively. Gram-positive bacteria, Streptococcus pyogenes and Streptococcus agalactiae, showed lower resistance potentials (MIC= 0.78%, 3.125%
respectively) (MBC=1.36%, 6.25% respectively) to the essential oils compared with Staphylococcus aureus. Escherichia coli showed higher sensitivity (6.25% and 12.5% for MIC and MBC, respectively) than Klebsiella pneumonia and Pseudomonas aeruginosa to the B. napus seed oils. Gram-positive bacteria were
more sensitive to the tested essential oils than Gram-negative bacteria. Overall, four different seed varieties have important chemicals and fatty acids. Oleic acid was the most common carboxylic acid (fatty acid) and 2,4-decadienal with hexanal were the most prevalent aldehydes in four seed oils. Tested B. napus seed essential oils
showed antimicrobial activities against various Gram-positive and negative bacteria and Candida albicans, with Pactol seed oils exerting the highest activity.
The primary objective of this study is to examine the effects of a do-it-yourself (DIY) technique on the reading comprehension performance of fifth-grade students in preparatory schools. In order to accomplish the objective of this research, it is posited that a null hypothesis can be established, suggesting that there are no statistically significant disparities between the average scores of the experimental group, which is instructed using a do-it-yourself (DIY) strategy, and the control groups, which are instructed using a prescribed method, in terms of their reading comprehension attainment. Developing a pre- and post-achievement test. Both groups have been equalized in terms of characteristics such as parental educational leve

Show MoreKnowing the distribution of the mechanical rock properties and in-situ stresses for the field of interest is essential for many applications concerning reservoir geomechanics, including wellbore instability analysis, hydraulic fracturing, sand production, reservoir compaction, subsidence and water/gas injection throughout the filed life cycle. Determining the rock's mechanical properties is challenging because they cannot be directly measured at the borehole. The recovered carbonate core samples are limited and only provide discrete data for specific depths. This study focuses on creating a detailed 1D geomechanical model of the Mishrif reservoir in the Nasriyah oil field to identify the fault regime type for each unit in the format

The research aims to identify the impact of the visual teaching strategy by using infographics mathematics achievement for intermediate grade students. The experimental research method was adopted, as the experimental design of two independent and equal groups with a post test was used, whereas the experiment was applied on a sample consisting of (52) male students from first- intermediate grade students in (Al-Haq Al-Mubin intermediate school for Boys) of the General Directorate in Anbar Governorate - Department Education in Fallujah for the academic year (2021-2022), and the research sample was distributed equally on the two research groups, and Division (B) was chosen randomly to be the experimental group, while Division (A) was the cont
