Introduction: Work environments create the basis for arduous nursing work. This is what led us to research the factors of arduousness in the exercise of the health profession in North Benin, through this study. Methods: This is a cross-sectional and descriptive study which focused on health professionals in the health zones of Parakou-N’dali and Tchaourou. The sampling was an exhaustive census. All health workers who had given their free and informed consent were included. The data was collected using a questionnaire. The variables studied were the factors of arduous work and socio-professional characteristics. The data collected was processed and analyzed with the Epi info 7.***.0.1 software. Results: A total of 692 were surveyed, the participation rate was 85.11% and the sex ratio (M/F) equal to 0.7. The average age was 38 years old. Nurses made up 32.66% of the sample. They were 86.42% subject to night work and 82.66% to alternating work. Overall, 70.23% worked more than 40 hours per week. Between 78.12% and 96.46% of non-specialist doctors, nurses, midwives and biomedical analysis technicians were required to work night shifts. Nurses, midwives, radiology and laboratory technicians were between 89.53% and 97.35%, organized in alternating work. In the sample, 55.20% complained about the insufficient number of work materials, 26.29% handled harmful chemical substances. Among those surveyed, 58.14% had been attacked.

Introduction: Living and working conditions are increasingly conducive to a sedentary lifestyle. Many administrative workers are exposed daily to long hours of work in a prolonged sitting position, which can favour the onset of diabetes. The aim of the study was to determine the prevalence and factors associated with diabetes among workers at a town hall in Benin in 2019. Methods: This was a descriptive cross-sectional study conducted from December 2018 to January 2019. Exhaustive recruitment was carried out. Data were collected during a face-to-face interview, using a standardized questionnaire including socio-professional factors, behavioral factors, anthropometric measurements, and blood glucose. Frequencies were calculated. Frequencies were compared using the chi-square and Fisher tests. The significance threshold was 5%. Results: A total of 85 workers were included. Their mean age was 41.55 ± 9.82 years, with a sex ratio of 6.1. = The prevalence of diabetes was estimated at 8.2% [95% CI: 3.38 - 16.23%] and 3 of the workers knew they had diabetes. A family history of diabetes was associated with diabetes (p = 0.032). Occupationally, 10.77% of permanent employees had diabetes, compared with 0.0% of non-permanent employees;12.50% of employees with at least 10 years’ seniority had diabetes, compared with 7.25% of those with less seniority;19.05% of employees who spent at least 6 hours a day sitting at work had diabetes, compared with 4.69% of those who spent less time sitting. Conclusion: Preventing chronic disease in the workplace is part of promoting workers’ health, and must take into account occupational factors such as prolonged sitting.

Introduction: Coronavirus 19 disease (COVID-19) often presents several serious complications in patients. 25-hydroxyvitamin D [25(OH)D] deficiency is considered a risk factor for severe forms of the disease. Objective: The objective of this work was to determine the prevalence and factors associated with vitamin D deficiency in patients with COVID-19 in Parakou in 2021. Methods: The method used was a descriptive and analytical cross-sectional study with prospective data collection that covered the period of August 1, 2021, to December 30, 2021. It concerned patients with COVID-19, symptomatic or not, in the commune of Parakou, selected by non-probability sampling. The 25(OH)D assay was performed by an enzyme immunoassay using the heterogeneous phase competition technique. Logistic regression was used to determine the factors associated with 25(OH)D deficiency at the 5% threshold. Results: A total of 197 patients with COVID-19 were included in the study with a mean age of 35.4 ± 15.2 years;with a female predominance (52.3%). The overall prevalence of 25(OH)D deficiency was 31.5% (95% CI [25.1 - 38.5]);it was 32.0% in females and 30.8% in males. 25(OH)D deficiency was more observed in patients ≥ 60 years than in patients < 60 years with no significant difference (p = 0.121), and in females (32.0%) than in males (30.8%) with no significant difference either (p = 0.857). Diabetes (p = 0.036), overweight or obesity (p = 0.032), severe disease forms (p = 0.003) and rhinitis (p = 0.009) were significantly associated with 25(OH)D deficiency. Conclusion: One-third of patients with COVID-19 in Parakou in 2021 were 25(OH)D deficient. 25(OH)D deficiency is associated with the severe form of the disease and with comorbidities justifying supplementation of this vitamin to patients with COVID-19.

The effect of side walls on particles mixing in rotating drums

引用

Particuology 2023年第1期72卷 112-121页

作者： Aman Jain fabien Evrard Berend van Wachem Chair of Mechanical Process Engineering Otto-von-Guericke-University MagdeburgUniversitaetsplatz 2Magdeburg 39106Germany

In this paper, we study the effects of the presence and shape of side walls and of the overall length of rotating cylindrical drums on the mixing of particles with differing sizes by application of the discrete element method (DEM). By varying the semi-axis of the spheroidally shaped side walls and the length of the overall drum, we observe the formation of circulation patterns near the side walls. Although there is a vast amount of literature studying mixing regimes in rotating drums, little is known about the effect of the side walls of the drum on particle mixing. The results of our study demonstrate that introducing curved side walls induces a strong circulation pattern near these side walls, but has, paradoxically, a negative impact on mixing and actually promotes segregation. The cause for this segregation is the difference in velocity of differently sized particles near the curved side walls. Large particles accumulate at the curved side walls, whereas small particles move away from the curved side walls. When the length of the drum is increased, the overall effect of the side walls is decreased, although it does remain observable, even in very large drums.
