The objective of the study was to make an assessment of the pre-donation capillary hemoglobin dosage for the year 2020 of the fixed collection, of the Blood Transfusion Center of Yamoussoukro. Method: This is a retrospective study that took place at the Yamoussoukro Blood Transfusion Center. The data collection related to all old and new blood donors were deemed suitable for the fixed collection of the year 2020. The method chosen for the pre-donation control is that of the portable hemoglobinometer of the HémoCue<sup>®</sup> type, more precisely 201+. Results: Of the 1160 blood donors in the study, the pre-donation hemoglobin level was not measured in 787 (67.8%) subjects of either sex. Of the subjects who had a pre-donation hemoglobin level performed, 97 (26%) blood donors had a sub-standard hemoglobin level, including 15 females and 82 males. Conclusion: Pre-donation hemoglobin testing of blood donors is effective in Yamoussoukro. However, efforts must still be made to improve the quality of the blood collected and to protect blood donors.展开更多

Each leader has a constrained correspondence. By using a collective fixed point theorem in locally FC-uniform spaces due to author, some existence theorems of equilibrium points for the multi-leader-follower generalized constrained multiobjective games are established under nonconvex settings. These results generalize some corresponding results in recent literature.展开更多

As applications, some new collectively fixed point theorems and coincidence theorems for two families of set-valued mappings defined on product space of noncompact topological spaces are obtained under very weak assumptions.
