Radiological assessment for the East Baghdad oilfield-southern part was conducted in the current study. 10 samples (scale, soil, sludge, water, and oil) from the different stages of oil production were collected. 232Th, 226Ra, and 40K in the samples were analyzed with 40% efficiency for Gamma spectrometry. system based on HPGe. The findings indicated that the examined sites exhibit comparatively lower levels of NORM contamination, in contrast to other global oilfields. Nevertheless, certain areas, particularly those within separation stages, demonstrate relatively elevated NORM concentrations exceeding the global average in soil and sludge. The maximum value of 226Ra, 232Th, was found in sludge sample the findings indicated that over 70% of the sampled locations exhibited concentrations of Norm that surpassed the worldwide average values. The highest exposure dose rate readings within the study areas reached 0.13 µSv/h, which exceeds the worldwide dose rate of 58 nGy/h as reported by UNSCEAR. Radiation exposure dose and hazard indices were calculated using the concentrations of 232Th,226Ra and 40K within samples. Indeed, the indices encompass various factors, these metrics provide a comprehensive understanding of the radiation exposure and associated risks. The study indicated that the relatively more contaminated stages within the oil production stages are the 1st separation stage, desalter stage and the waste pit stage where the higher concentrations of 226Ra, 232Th and exposure rates are recorded. Generally, the site exposes dose rate within an acceptable rate. Generally, the values of all hazard indices indicate that samples of some locations have values higher than the values recommended by UNSCEAR and ICRP.
The research aims to achieve proof of convergence between optimal costs and standard costs in calculating costs for the economic unit, support efforts aimed at adopting optimal costs in cost accounts and accounting thought in general, and achieve benefit from the theory of convergence between optimal costs and standard costs in the field of achieving actual costs in The economic unit in order to reduce and converge, and this came to address the possibility of adopting the concept of optimal costs in the production costs calculations for the purposes of rationalizing administrative decisions, and rationalizing the preparation of financial statements within management accounting.

... Show MoreBackground: The novel coronavirus disease (COVID-19) is caused by Severe acute respiratory syndrome coronavirus 2 (SARS-Cov2) which utilizes angiotensin converting enzyme2 (ACE2) to invade the host cells. This membrane-bound peptidase is widely distributed in the body; its activity antagonizes the renin-angiotensin-aldosterone system (RAAS). Once SARS-Cov2 enters the cell, it causes downregulation of ACE2, resulting in the unopposed activation of RAAS. The unregulated activity of the RAAS system can deteriorate the prognosis in COVID-19 patients. A soluble form of ACE2 (sACE2) was reported to have a role in the SARS-Cov2 invasion of the susceptible cells.
