Horizontal Visibility Obstruction Due to LTV
In spring 2002, the Center for Advanced Traffic System Simulation (CATSS), at the University of Central Florida, acquired a sophisticated reconfigurable driving simulator. This driving simulator is capable of supporting research in driving simulation, driver training, traffic engineering and human factors. However, it is crucial to assess the validation of the driving simulator since the credib...
متن کاملCharacterization of anopheline (Diptera: Culicidae) larval habitats in Nouakchott, Mauritania.
BACKGROUND & OBJECTIVES Despite the increasing number of reported autochthonous malaria cases in Nouakchott and the identification of Anopheles arabiensis as the major malaria vector in this Saharan city, anopheline larval habitats have never been identified so far. The objective of this study was to identify and characterize anopheline larval habitats in Nouakchott. METHODS During September ...
متن کامل[HIV seroprevalence among STD patients in Nouakchott and Nouadhibou (Mauritania)].
This work presents the results of the behavioural and serologic survey on HIV/AIDS conducted from December 2007 to December 2008 among the group of STD (sexually transmitted disease) patients, supposed to be at HIV infection risk. In Mauritania, the last survey of HIV seroprevalence among the STD patients goes up to the year 1995 (the prevalence was estimated then to be 0.9%). The goal was to d...
متن کاملMalaria in Mauritania: the first cases of malaria endemic to Nouakchott.
The current situation of endemic malaria in Mauritania is not clear since, in most health centres, suspected malaria cases are not confirmed by parasitological analysis and diagnosis is based on clinical symptoms alone. To obtain reliable data about malaria in this country, thin and thick blood smears were taken from patients with symptoms compatible with the illness, who attended two hospitals...
متن کاملHeat transfer enhancement due to air bubble injection into a horizontal double pipe heat exchanger
If an air flow is injected into a liquid fluid, many ambulant air bubbles are formed inside the fluid. Air bubbles move inside the liquid fluid because of the buoyancy force, and the mobility of these air bubbles makes sizable commixture and turbulence inside the fluid. This mechanism was employed to enhance the heat transfer rate of a horizontal double pipe heat exchanger in this paper. Howeve...
