The lifetime risk of acquiring HIV infection in many rural as well as urban areas of southern Africa is currently as high as two-in-three. For women, much of this risk still accrues rapidly at young ages despite high levels of knowledge about HIV/AIDS. Thus, programmes that are more participatory and address underlying structural and community-level factors appear to be essential. We use cross-...

More than 200 large-eddy simulations of long-lived contrails from several-seconds age until their demise have been performed and their lifetime-integrated behavior has been analyzed. The simulations employ sizeresolved microphysics and include variations of effective ice crystal number emission index, temperature, relative humidity with respect to ice, stratification, shear, supersaturated-laye...

conclusions the results of this study showed that self-management interventions are effective in promoting self-efficacy in patients with sickle cell disease. thus, the use of self-management programs is advisable to change behaviors and promote self-efficacy in such patients. background patients with sickle cell disease suffer from various complications during their lifetime. in order to cope ...

This article presents a very successful technique for reducing the energy consumption and increasing lifetime of wireless sensor networks. To evaluate the efficiency of the proposed Adaptive Scheduling Algorithm in term of network lifetime, we built up a scenario containing network topology, synchronization techniques, energy model and management of data transmission and scheduling. For the sam...
