Background: The high rates of infection and mortalities initially caused by COVID-19, made anxiety and fear very common. With the increase of vaccination coverage, it is expected to detect changes in risk perception and fear of COVID-19, especially with the emergence of what so called "Pandemic Fatigue". The aim of this study was to assess COVID 19 risk perception after the vaccination era. Methods: This is a cross-sectional analytical study, using an online questionnaire including socio-demographic questions and COVID-19 risk perception questions. Results: The questionnaire was filled by 509 participants. Sociodemographic characters of the participants didn't affect the COVID-19 risk perception. The mean and median perceived efficacy scores were significantly higher in participants with no prior history of COVID-19 infection. Participants with positive attitude towards COVID-19 vaccine had significantly higher risk perception. Conclusion: COVID-19 risk perception is still query and not fully understood. This necessitates more studies to be conducted to explore it among different groups which may relate it to different determinants. Social media is the main source of knowledge among participants and should be professionally used for enhancing positive attitudes towards COVID-19 vaccination. [ABSTRACT FROM AUTHOR]

A field experiment was conducted during the 2017-2018 and 2018-2019 cultivation seasons in Sheikh Mohamed location, which is about 25 km to the north of Mosul city in order to evaluate yield, yield components and quality of three sesame genotypes (Promo, Uzbekistan and Kenana), three rates of phosphorus fertilizer (0, 50 and 100 kg P2O5) and three plant densities (41666, 55555 and 83333 plant.ha-1). The trials were conducted according to Complete randomize block design with split - split plot with three replications. Analysis showed that yield and most of the yield components and quality were affected by fertilizers, genotypes, and plant density. The addition of 100 kg.ha-1 of phosphorus treatment gave higher seed and oil yield than that of control and 50 kg.ha-1 application. Genotypic difference was observed in all traits. Uzbekistan genotype gave a high level for plant height, number of primary branches, number of capsule.plants-1, number of seeds.capsule-1, 1000 seeds weight, seed yield, total seed yield, seed oil content and oil yield in the two growing seasons. Plant densities of 41666 plant.hectar-1gave the highest number of primary branches, number of capsule per plants-1, number of seeds.capsule-1 and 1000 seeds weight in the two growing seasons 2017-2018 and 2018-2019.
