Social services of proximity, a reflection of a society
Social services of proximity, a reflection of a society
The communities, large and small, across Europe are in a phase of economic and social transformation through the decline in traditional industries, the rapid immigration, an ageing population and higher prices for housing, and by an increase in street crime and anti - social.
Social services and its partners in the sectors of education, health, employment and housing, realize that they must work together to make a difference in the lives of vulnerable individuals and to strengthen community cohesion.
On July 4 and 2.3, is organized in Paris by the European Social Network, the 16th European Conference of social services. The conference recognizes the important role of proximity services in the communities in constant change, sometimes divided on issues and they work, and explores the experiences of many European countries in this field. http://www.esn-eu.org

Reduction of fuels by 15%
Engineers at the University of Delft (Netherlands) have developed a system of carenagens side for lorries, which reduces fuel consumption by up to 15%. The new solution aerodynamic tests showed the practical results higher than predicted by computer simulations on.
The set is composed of aerodynamic "skirts" side and a "tail" that reduces the so-called "track", a set of vacuum and air currents that exist in the rear of the trailer to the extent that the truck moves.
Based on the real tests, the researchers estimate that the investment in the placement of side skirts and tail of the truck is recovered in two years. The set aerodynamic as a whole reduced air resistance by 30%, which translates into a fuel economy of 15%.
