Open Journal of Applied Sciences 2024年第3期14卷 687-706页

Perovskites are a category of materials with a unique crystal structure that allows them to absorb sunlight efficiently. This efficiency is particularly high in the case of CH3NH3Pb1-xSnxI3 mixed perovskites. The combination of lead (Pb) and tin (Sn) in this matrix provides a broad spectrum of sunlight absorption, enabling the generation of a larger voltage and, subsequently, increased power. The primary objective in solar cell development is to maximize the conversion of sunlight into electricity. Mixed perovskites like CH3NH3Pb1-xSnxI3 have demonstrated significant potential in this regard. Their tunable bandgap, courtesy of varying the Pb: Sn ratio, allows for the optimization of sunlight absorption. The result is solar cells that surpass many conventional counterparts in terms of energy efficiency. Another significant advantage of these mixed perovskite solar cells is their cost-effectiveness. They can be manufactured using solution-based processes, which are less expensive than the high-vacuum methods required for traditional silicon solar cells. While the prospects for mixed perovskite solar cells are undeniably promising, there are concerns about the toxicity of lead, a key component of these cells. Lead is known to have harmful effects on the environment and health. The aim of our work is to reduce or eliminate lead toxicity in the perovskite cell while maintaining its efficiency. Thus, in a theoretical and experimental approach, we obtained following efficiencies of samples: CH3NH3PbI3 (22.49%) CH3NH3Pb0.75Sn0.25I3 (22.72%), CH3NH3Pb0.5Sn0.5I3 (23.00%) CH3NH3Pb0.25Sn0.75I3 (22.61%), CH3NH3SnI3 (22.38%).

Aim: This paper aims to evaluate the epidemiological and pathological aspects of stomach cancer at Koutiala District Hospital. Methods: This was a retrospective study carried out in the General Surgery Department of the Koutiala District Hospital Health Centre. The records of patients admitted for stomach cancer in the period from August 1, 2017 to December 31, 2022 were collected. Patients who underwent surgery for stomach cancer were included in the study. Patients who had not undergone surgery were excluded. Results: We collected records from 40 patients operated on for stomach cancer. The median age was 58.4 years ± 5.7. Men were in the majority with 72.5% The sex ratio was 2.6. The incidence rate of stomach cancer in the general population in the circle was 4.9 cases per 100,000 population. Patients had a history of gastric ulcer in 90%, Helicobacter pylori infection in 47.5% and a notion of excessive salt consumption in 47.5%. The median duration of disease progression was 5 years ± 2.3. The seat was antro-pyloric in 77.5%. The cancer was ulcerative budding in 23 patients. Adenocarcinoma was the histological type in all patients. The cancer was classified as stage III in 30 cases and stage IV in 10 cases. Palliative surgical treatment was the most performed (47.5%). Postoperative morbidity was 15% and mortality was 42.5% at one year. Conclusion: Stomach cancer is common in the ward. Most patients consult at the stage of metastasis. Palliative surgery remains the most practical. Postoperative morbidity and mortality is very high.

Introduction: Vaccination coverage in Côte d’Ivoire over the period 2011 to 2015 was below the target of 95% for all antigens. The objective of this study was to analyze the vaccination status of children aged 6 to 30 months with a view to improving vaccination coverage. Patients and Methods: This was a descriptive cross-sectional study which took place from June to September 2018 in a tertiary health center, focusing on children aged 6 to 30 months with a correctly completed health record. The parameters studied were sex, age, educational level of mothers, dates of vaccine administration and reason for missed vaccination opportunities. Results: We retained 212 children. The sex ratio was 1.21 and 93% had received the BCG vaccine before the age of 1 month. The average ages of combined and co-administered vaccines for the 1st and 2nd doses were 7.66 ± 3.81 and 12.88 ± 3.95 weeks, respectively. The median was 16.57 weeks for the 3rd dose. The proportion of vaccinated subjects was greater than 90% for the BCG vaccine and the 3 doses of combined vaccines, and 77% for the yellow fever and measles vaccines. The reasons for non-vaccination were attributable to the children’s parents and health facilities. Conclusion: Improving vaccination coverage requires regular supply of vaccines to centers, and the involvement of all health professionals, community and religious leaders in the vaccination awareness process.
