Mapping malaria transmission in West and Central Africa.
We have produced maps of Plasmodium falciparum malaria transmission in West and Central Africa using the Mapping Malaria Risk in Africa (MARA) database comprising all malaria prevalence surveys in these regions that could be geolocated. The 1846 malaria surveys analysed were carried out during different seasons, and were reported using different age groupings of the human population. To allow c...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
Smallpox eradication in West and Central Africa.
The history of smallpox eradication in the 20 countries of West and Central Africa from Mauritania to Zaire is recounted, including background, evolution of strategy, assessment, maintenance, costs, and significance of the campaign. Smallpox was endemic in these countries, peaking each year at the end of the spring dry season, usually occurring in isolated villages only periodically. The aver...
متن کاملIsodose mapping and its radiological implications in Lagos state, Nigeria
Background: The annual effective dose equivalent (AEDE) due to ionizing radiation in a coaster area in Nigerian has been determined using Geiger-Muller counter. Materials and Methods: isolevels in the study area were represented by using the kriging interpolation technique on ArcGIS 10.1 software. Duncan multiple range test was performed using Statistical Package for Social Sciences (SPSS). Res...
متن کاملData Integration for Climate Vulnerability Mapping in West Africa
Vulnerability mapping reveals areas that are likely to be at greater risk of climate-related disasters in the future. Through integration of climate, biophysical, and socioeconomic data in an overall vulnerability framework, so-called “hotspots” of vulnerability can be identified. These maps can be used as an aid to targeting adaptation and disaster risk management interventions. This paper rev...
