Community mobilization and peer education in a HIV-STI prevention program for university students

Popular Abstract in Swedish Det är en viktig uppgift för samhället att förebygga HIV och STI (sexuellt överförbara infektioner) bland ungdomar. Under de första åren av 1990-talet, när denna studie genomfördes, ökade dessa infektioner på ett oroväckande sätt. Detta gällde särskilt klamydiainfektionerna och nästan 25% av studenterna vid Lunds universitet rapporterade att de hade haft en konstaterad Slowing the incidence of HIV and STI among young people requires that they change their sexual behaviours. There is evidence that community-based interventions that target multiple levels of influence can be effective. In community mobilization different segments and sectors of a population are directly involved in problem identification and in the design and implementation of programs. The proces

Applicable science categories are planets and planetarysystems, stars and stellar systems, galaxies and galaxy clusters, andcosmology. ELT observations are needed for our own and other pla

Retrofocusing of Acoustic Wave Fields by Iterated Time Reversal

In the present paper an iterative time-reversal algorithm, that retrofocuses an acoustic wave field to its controllable part is established. For a fixed temporal support, i.e., transducer excitation time, the algorithm generates an optimal retrofocusing in the least-squares sense. Thus the iterative time-reversal algorithm reduces the temporal support of the excitation from the requirement of neglig

Optical spectroscopy for tissue diagnostics

Biomedical Optics as an interdisciplinary field of science has been developed during many years and is experiencing tremendous growth, to cover a wide range of optical techniques and methods, utilized for medical therapeutic and diagnostic purposes. Biomedical optics contributes in the introducing methods and creation of devices used in healthcare of various specialties, such as ophthalmology, car
