This study evaluates the drug abuse prevention needs for Spanish youth in municipalities with a population below 7, 000 inhabitants in the province of Valencia, Spain. The primary goal of the project was to generate policy and to identify possible courses of drug prevention in these towns. The project utilized the basic RARE model. Grounded Theory was used to frame the qualitative analysis. Interviews with local cultural experts provided strong evidence that many specifically mandated prevention needs are not adequately covered in small municipalities. The data emphasizes the ways in which young people are critical of the prevention actions directed at them. The recommended programs emphasize (1) joint actions using youth networks, (2) educating parents to take an active role in the prevention chain, (3) extending the range and availability of leisure activities, and (4) making sure that the information campaigns are adapted to the interests of young people.

A compact dual-band equatorial helical antenna for TTC (telemetry, tracking, and control) applications in satellites is presented. The network feeding system of the antenna was also designed, analyzed, and measured to achieve circular polarization. A Moment Method code was used to evaluate the performance of both the helical antenna and the feed-circuit network. The whole system was optimized to fulfill rather strict specifications, while maintaining quite small size and weight. A prototype of the helical antenna was fabricated and measured. The design process of the geometrical model, and comparisons between the predicted and measured values, are presented. The results led to the conclusion that it is a very suitable antenna for operating at S band. [ABSTRACT FROM AUTHOR]
