Previous measurement campaign, realized in France in 2005, has shown that an infrasound station can clearly measure thunder when lightning occur within 75 km from the station. In this paper, infrasound data recorded in Ivory Coast since 2005 are analyzed and compared to WWLLN data in order to quantify statistically the main trends observed in 2005. The main results are : (1) the (infrasonic) th...

Ecological surveys were carried out to assess the population characteristics and epidemiological importance of Glossina palpalis palpalis (Rob-Desv.), 1830 in the human trypanosomiasis focus of Vavoua in the forest zone of Ivory Coast. G. p. pulpalis was widespread in all components of the ecosystem: forest, interstitial savannahs, coffee plantations, tracks and villages. Most flies were caught...

Isolates of yellow fever (YF) virus from Africa (Senegambia, Central African Republic, Ivory Coast, Burkina Faso) and from South America (Panama, Ecuador, Trinidad) were examined by oligonucleotide fingerprinting of the 40S genome RNA. Geographically isolated and epidemiologically unrelated viruses were very distinct. On the basis of the T1 oligonucleotide fingerprints of each isolate, four geo...

Towards the consolidation of peace and national development, Ivory Coast must overcome the lack of cohesion, responsible for the emergence of two civil wars in the last years. As in many African countries, ethnic violence is a result of the way territories are organized and the prevalence of some groups over others. Nowadays the increasing availability of electronic data allows to quantify and ...

Objectives: The main objective of this study was to identify some yam assessions that are tolerant to the most invasive nematodes like Scutellonema bradys and Meloidogyne spp. Methodology and results: New assessions of Dioscorea spp. were screened in the savanna zone of central Côte d’Ivoire. Fourteen of D. alata and thirty seven assessions of D. rotundata were tested respectively and separatel...

(from Central African Republic, Ivory Coast, and Senegal) nilensis Linsenmaier, 1959 (Ivory Sudan). lectotype of leachi var. cyanea du Buysson, 1908 designated. Illustrations are presented.

This study examines the determinants of households’ decision to migrate from Burkina Faso to Cote d’Ivoire, a leading country in the Regional West African Union. The paper, unlike most of the previous works, uses a dataset constituted from a two-sided survey conducted in 2002 at the origin and the host country. Therefore, it enables to study two groups of migrants: the seasonal and the permanen...

Economic growth and child welfare are simultaneously affected not only by HIV but also by other economic, military and social events, such as natural disasters, humanitarian conflicts and changes in terms of external trade. Disentangling the individual impact of each of these different effects is complex. It is possible – for instance – that the economic impact of HIV rises more than proportion...
