   Författare :Ramiro Pillco; Avdelningen för Teknisk vattenresurslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENSO; terminal lake; bathymetry; lake level; water balance; lake routing; paleolakes; climate change; precipitation pattern; intermittent rivers.; Desaguadero River; Lake Titicaca; Lake Poopó;

   Sammanfattning : The Bolivian Altiplano is situated between two mountain ranges, the western and eastern central Andes in South America. It has two major lakes, Lake Titicaca to the north, and Lake Poopó to the south, which both are important for the nature as well as for the living conditions on the Altiplano. The two lakes are the remnants of large paleolakes. LÄS MER

   Sammanfattning : The Bolivian Altiplano (BA) is a high plateau located in the western part of the country at an altitude of 3,600 to 3,900 meters above sea level and is bordered by the Eastern and Western Cordillera. Within the BA there is a large endorheic hydrologic system linking the Titicaca Lake in the north the Desaguadero River, lakes Uru-Uru and Poopó in the central part; and the Lacajahuira River and Coipasa and Uyuni salt pans in the south.

   Sammanfattning : Certain climatologically-adverse conditions in the basin of the Poopo Lake, located on the high plateau of the Bolivian Altiplano, have prevented the existence of a reliable agricultural system and the impact on the population of the area has been severe. These problems have been the main motivation in choosing this region for this particular study. LÄS MER

5. 9. Patrones de Asentamiento Precolombino del Altiplano Boliviano : Lugares Centrales de la Región de Quillacas, Departamento de Oruro, Bolivia

   Nyckelord :HUMANIORA; HUMANITIES; Bolivia; Andean central places; socio-dynamic units; social construction; ayullus; Tiwanaku; Quillacas- Azanaques; markas; Archaeology; Arkeologi;

   Sammanfattning : Archaeology in Bolivia has two strong tendencies: nationalism and regionalism. The proposal aims for an academic reconstruction and expansion of this science in order to develop new scientific criteria, that can be institutionalized and become normative to the whole country to cover the expectations of different regions with regard to its past.

7. 10. Synthesis of Zeolites from Bolivian Raw Materials for Catalysis and Detergency Applications

   Författare :Gustavo Garcia; Linda Sandström; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical Technology; Kemisk teknologi;

   Sammanfattning : Zeolites are very useful in many technological applications such as catalysis, separation and purification of gases and solvents, ion-exchange, etc. The production of zeolites is nowadays carried out with a variety of reagents, such starting materials render large scale production of zeolites expensive.
