Background: Forensic medicine is the branch of medicine that deals with applying medical knowledge to establish facts in civil or criminal cases, such as investigations into the cause and time of death. In Iraq, people's knowledge about forensic doctors' profiles is unknown, so this study aims to assess the general population's knowledge regarding forensic doctors. Methods: This is a cross-sectional study that involved 644 participants from different provinces in Iraq using a self-administered questionnaire published via social media websites. The survey involved questions about the sociodemographic status of participants and twelve questions about forensic doctor duties, which were listed in the Iraqi constitution. These were tested for internal consistency with an alpha Cronbach value of 0.82. The data was analyzed using Statistical Package for the Social science (SPSS) version 23. Results: The mean number of questions correctly answered was 7.35 with a standard deviation of 3, 9.5% of the sample answered all the questions correctly, 30.4% answered from 9 to 11 questions, 20.5% from 7 to 8, 28% from 4 to 6, 9.4% from 1 to 3 and 2.2% answered all questions wrongly. The highest awareness was about the duty of dissecting bodies, identifying the remnants' identity, and identifying the cause of death. The lowest awareness was about public morality issues as a duty of the forensic doctor. There was a statistically significant association between the number of correctly answered questions and gender, age, marital status, and education level. Conclusion This study shows moderate knowledge and awareness about forensic doctors among Iraq's general population.

This work aims to the identify level of hybrid nanocomposite coatings of a stainless steel alloy that is used in the manufacture of mineral reservoirs for the storage of oil products in the oil products distribution company (Opdc). Corrosion is one of modern society's most serious engineering problems where losses incurred due to it each year are estimated at billions of dollars. Technological options have to be exercised to protect against corrosion and an effort to combat these losses. To overcome this severe problem, several successful efforts have been made using corrosion inhibitors. Corrosion inhibitors are compounds used in low concentrations to prevent or slow down the corrosion process. The used metal (low carbon steel St-37) was coated with zinc phosphate as an initial layer, cellulose nitrate reinforced with MgO nanopowder by weight percentage (3 wt. %) as an intermediate layer, and epoxy resin reinforced with weight reinforcement percentage (2 wt. %) of particles (MgO+coke coal (1:1)) as a final layer. In addition, a cognitive scale was prepared from (hardness, adhesion strength, chemical corrosion test as well as electrochemical corrosion test. It was found the hardness increased with coated by an initial layer and the value of adhesion strength of triple coating layers was (232 Psi). Chemical and electrochemical corrosion tests have shown the efficiency of prepared coating layers in corrosion inhibiting and metal protection. The used inhibitors in the work are inexpensive materials that allow solving the problem of rational nature management by reducing corrosion and providing the transition to the use of environmentally safe efficient technologies
