The co-evolution of social relationships and individual behavior in time and space has important implications, but is poorly understood because of the difficulty of closely tracking the everyday life of a com- plete community. We offer evidence that relationships and behavior co-evolve in a student dormitory, based on monthly surveys and location tracking through resident cellular phones over a period of nine months. We demonstrate that a Markov jump process could capture the co-evolution in terms of the rates at which resi- dents visit places and friends. Our co-evolution model will be useful in bridging sensor networks data and organizational dynamics theories, simulating different ways to shape behavior and relationships, and turning mobile phone data into data products.

The objective of this work is to improve the physical and mechanical properties of stabilized earth blocks (BTC) used in construction in the Ndé department of Cameroon. To achieve this, two stabilizers, cement and sawdust, were used at varying percentages of 0%, 4%, 6%, and 8%. Physical characterization tests, including natural water content, specific weight, jar test, Protor, and Atterberg limits, were conducted. Additionally, mechanical tests, such as compression and three-point bending, were performed. The results show that as the amount of stabilizer increases, the density of BTC decreases. The samples with 8% sawdust have the highest density, while those without stabilizers have the lowest. Porosity decreases as sawdust and cement content increases, with smaller values observed in samples with 8% sawdust or cement. Our tests indicate that blocks stabilized with cement have slightly higher compressive strength than those stabilized with sawdust. However, the water absorption rate increases with higher sawdust content.

Background: Hemodialysis is the most widely used renal replacement therapy in developing countries such as Cote d’Ivoire. Objective: To study the outcome of chronic hemodialysis patients in public centres in Abidjan using data from the Renal Registry of Cote d’Ivoire (2RCI). Method: This was a prospective analytical cohort study of End Stage Kidney Disease (ESKD) patients undergoing iterative hemodialysis in the network of public hemodialysis centres in Abidjan and who had been registered in the 2RCI register by September 2018. Results: Our study involved 363 cases out of 379 patients registered in the 2RCI registry database in 2018. The mean age of the patients was 47.3 ± 12.1 years, with a male predominance (sex ratio 1.97). In 70.24% of cases, they had no health insurance. The average duration of dialysis for our patients was 6.94 ± 4.1 years, with extremes of 2 and 28 years. This duration was less than 5 years in 44.3% of cases, between 6 and 10 years in 42.9% and more than 10 years in 12.6% of cases. The comorbidities found were hypertension in 95.6% of cases, diabetes in 7.8% and HIV in 4.6%. Anemia was found in 68% of cases and stroke in 8.6%. During the study period, 161 deaths were observed, representing a mortality rate of 44.35%. Acute lung oedema (29.8%), stroke (6.8%) and other cardiovascular diseases (19.3%) were the main causes of death. In multivariate analysis, factors such as age ≥ 65 years (HR = 3.66;CI 95% = 1.55 - 8.67;p = 0.003), “married/coupled” status (HR = 2.02;CI 95% = 1.24 - 3.31;p = 0.005) and normal weight at the start of dialysis (OR = 9.59, CI95% = 4.19 - 21.95;p = 0.001) were associated with the risk of death. Conclusion: Hemodialysis is performed in Abidjan on young patients. The mortality rate after three years of dialysis is very high. Hence the need to pursue the policy of decentralizing public centres and optimizing access to dialysis in terms of quality and quantity in order to improve patient survival.

Agroforestry systems strongly characterize the Cameroonian agrarian landscape. Agroforests are among those structuring the ecotones of Mbam and Inoubou in the Central Cameroon region. Numerous works on agroecosystems of Central and South Cameroon, few have come out contribution of the structure of these traditional systems in the dynamics of the vegetation of these forest-savannah ecotones. The present contribution has the overall objective of demonstrating the structural efficiency of agroforests the dynamics of ecotone vegetation, but also in the conservation of biodiversity. To do this, a participatory analysis was carried out with 56 farmers distributed in the five villages of Makénéné. Botanical inventories supplemented socio-economic household surveys. The data collected was subjected to various analyzes (univariate test, analysis of variance, multivariate test, PCA, CAH). The results reveal that 55.2% of agroforests are less than 15 years old and those with an area greater than 1500 m2 predominate (33%). They are mainly young with generally small surface areas. The horizontal structure reveals that the largest diameter classes are those of [20 - 30 cm[ and [10 - 20 cm[ with a very low rate of basal area. Agroforests with trees over 10 m high are dominant in five villages of Makénéné. Two types of structural profiles characterize the agroforestry flora of the area, namely intensive pluristratified home gardens on savannah and intensive pluristratified agroforests under forest-savannah transition vegetation. Principal Component Analysis (PCA) and Ascending Hierarchical Clustering (HAC) show three Agroforest Clusters each. The PCA distribution reveals that woody biomass (Y) is strongly correlated with tree diameter (DBH) and significantly with height (Cluster 2). The age (AAG) (Cluster 1) of these agroforests, on the other hand, remains independent of the density (DST) of these trees (Cluster 3). The agroforests in the Nyokon, Carrière and Mocksud vil
