La detección temprana del VIH mediante el acceso a la consejería y prueba voluntaria durante el control prenatal facilitan el tratamiento anti-retroviral oportuno que disminuye la transmisión durante el embarazo y el parto, y en el puerperio, asociado a la lactancia materna. En la presente revisión se condensan los principales aspectos del manejo de la infección materna con VIH y del recién nacido expuesto. La aplicación de un protocolo integral de atención facilita la disminución de la transmisión a niveles menores de 2%.

In the case of multiobjective evolutionary algorithms, the outcome is usually an approximation of the Pareto-optimal front, which is denoted as an approximation set, and therefore the question arises of how to evaluate the quality of approximation sets. Most popular are methods that assign each approximation set a vector of real numbers that reflect different aspects of the quality. Sometimes, pairs of approximation sets are considered too. In this study, we provide a rigorous analysis of the limitations underlying this type of quality assessment. To this end, a mathematical framework is developed which allows to classify and discuss existing techniques.

Problems regarding the overlapping of hunting and breeding season on wild boar (Sus scrofa L.) are very common in almost all European countries. In Portugal, despite the wild boar's demographical increase, the information about the characteristics of its reproduction and other ecological aspects is very scarce or absent. The wild boar population from central Portugal was monitored during the last four hunting seasons (1995/96, 1996/97, 1997/98, 1998/99). Several reproductive parameters were studied. Frequency of pregnancy was greater in older classes and the average litter size of harvested pregnant females was low (4,14 ± 1,15) in relation with other populations from northern Europe. The influence of litter size on the age of females and its geographical variability are discussed. One reproduction period is observed with the peak of births in March. According to the obtained reproductive season, several considerations about wild boar population hunting and management in the centre of Portugal are presented.

Estos términos son fundamentales para entender cómo se produce la reproducción de la cultura y la educación. Al finalizar se contextualizará la aplicación de estos términos en la Licenciatura en Ciencias Sociales de la Universidad Distrital Francisco José de Caldas, analizando cuáles son los dispositivos pedagógicos aplicados en este programa de formación docente a la luz de la aplicación del Decreto 272 de 1998.

Main results showed that the 0.48 Pa Ar treatment promoted the most favorable changes: roughness increased from 15 to 17 nm for PC and from 12 to 30 nm for PP, while ...
