The latest Intergovernmental Panel on Climate Change (IPCC) report shows that sea-level rise, which has been accelerated since the 19th century resulting to the global warming, threatens coastal areas with high population growth. A Global Sea Level Observing System (GLOSS) assessment highlighted the lack of data in Africa, and in Côte d’Ivoire in particular. In order to estimate the evolutionary trend of sea level along the Ivorian coast, and to draw up preventive plans to protect properties and populations, we digitized 65 years of historical tidegrams recorded in the Ebrie Lagoon, using the “Surfer” and “Nunieau” software, then processed them using “T-Tide” and “U-Tide” software. The average levels were calculated using the Demerliac filter from complete daily (day and night) recordings for providing a usable database of 31 years of hourly lagoon data from 1979 to 2015. Our results show that a mean water level in lagoon is 1.04 m. The evolutionary trend in sea level, estimated in the lagoon via the Vridi canal, during the rainy season is the most significant at 2.93 mm/year. This is followed by the dry season, with a trend of 2.89 mm/year. The flood season trend is 2.78 mm/year. This suggests that marine water inflows dominate continental inflows. Our results highlight the vulnerability of Côte d’Ivoire’s coasts to the risk of marine submersion.

We determine the left eigenvector of a stochastic matrix M associated to the eigenvalue 1 in the commutative and the noncommutative cases. In the commutative case, we see that the eigenvector associated to the eigenvalue 0 is (N1,Nn) , where Ni is the i–th iprincipal minor of N=M–In , where In is the identity matrix of dimension n. In the noncommutative case, this eigenvector is (P1-1,Pn-1) , where Pi is the sum in Q《αij》 of the corresponding labels of nonempty paths starting from i and not passing through i in the complete directed graph associated to M .

Background: The advent of antiretroviral treatment has considerably increased the life expectancy of people living with HIV in recent years. The Central African Republic, despite challenges related to the socio-political context, is committed to achieving the UNAIDS 90-90-90 targets and to the elimination of AIDS by 2030 advocated by the WHO. Objective: To analyze survival among HIV-positive adult patients on antiretroviral therapy from 2015 to 2020. Methods: This was a history-based cohort study of patients started on ART. The main variable was survival. The Kaplan-Meier method was used to describe the survival curve since inclusion in the cohort and a multivariate Cox model was used to investigate factors associated with mortality on ART. Results: A total of 145 naive patients started ART at the Outpatient Treatment Centre (OTC) in 2015. A female predominance was observed in our study with 78.08% of cases. The analysis of the patients’ fate at the time of point of treatment showed that 58.62% of them were still in active care and 13.10% died. The probability of survival at 5 years was 0.82 and mortality was significantly associated with very advanced disease (WHO stage IV) (p = 0.047) and anemia (p = 0.039). Conclusion: The majority of patients were still in care at the endpoint and mortality was significantly related to advanced disease and anemia. Early management of people living with HIV combined with better quality of care would improve their survival.
