At the same time, the map unification and harmonization should be taken into account dur-ing the design process, since some visual conflicts appear when map symbols overlaid on the true color image. The objective of this research is to explore the rules in the process of true color image city map design based on chromatic and aesthetic knowledge. At the end, taking the Image Atlas of Guangzhou as an example, image color adjustment, road network presentation, and symbol de-signing issues will be discussed in the application.展开更多

The group M (Major) is the dominant group in Sub-Saharan Africa and its distribution is very heterogeneous;the diversity of the virus is more heterogeneous in this region than elsewhere in the world which follows a complex and specific algorithm because of geographical positions and countries. This distribution is very dynamic, evolving and unpredictable. This review aimed to expose the specifics of the HIV Type 1 epidemic in Central Africa, in terms of the different molecular variants of HIV published for the region compared to the geographic location. Both Type 1 and Type 2 of HIV are prevalent in sub-Saharan Africa due to distinct geographical contexts. HIV-2 is mainly documented in West and Central Africa, particularly in Cameroon, Guinea-Bissau, Gambia, Senegal, Ivory Coast and Burkina-Faso however HIV-1 infection is widely distributed across the continent. The HIV-1 epidemic in Sub-Saharan Africa is dominated by the Group M. The different subtypes respect a certain geographical distribution across the continent. West Africa is dominated by subtype A, East and South Africa are dominated by subtype C, while Central Africa is dominated by strains A, C, D, F, H, J, CRF01-AE and CRF02-AG. This review is the first to present de molecular diversity of HIV-1 in metropolitan cities in all central African countries. The Circulating Recombinant Form (CRF02_AG) and subtypes A and G are present in all Central African countries and are also the most commonly encountered;followed by the subtypes D, F, G, C, B, J, K and several Circulating Recombinant Forms that are not represented in all Central African countries.展开更多
