Directory of Open Access Journals Sweden. Actividad posmdernidad en suelos de sabanas de los Llanos Orientales de Venezuela convertidas en pasturas. Microbial activity in Eastern Venezuelan savannas turned into grasslands.

We studied the effects of season and management practices on chemical properties and biochemical parameters in a typical Ultisol soil of native and introduced pastures of the Eastern savannas of Venezuela. Sseason, soil management, and their interaction, significantly affected chemical properties and biochemical parameters. The total carbon and the water soluble carbon experienced a significant decrease during the wet pereiod. The basal respiration, the arginine ammonification AA and the fluoriscein diacetate hydrolysis showed showed a relatively low microbial activity.

The transformation of native savannas to pastures systems of B. The AA and the basal respiration were sensible indicators to estimate changes in soil.

An introductory chapter of world wide petroleum history is followed by a comprehensive record of the petroliferous basins of Venezuela. Exploration, productivity, production statistics, reserves, geologic structures, and the distribution of oil and gas fields are described separately for the Maracaibo-Falcon basin, Apure-Barinas basin, E. Venezuela basin, and Tuy-Cariaco basin. The descriptions include geographic distribution, geomorphologic outline of the basins, lithology and thickness of sediments, structural development, present structural conditions in which oil and gas fields occur, and their distribution in the basins.

Economic factors are discussed in an appendix. Gran Sasso, posmodernidwd sigillato. The authorities closed half of the Gran Sasso Centre and the experiments were stopped yesterday after faults were discovered in the security system in one of the three halls of the Laboratory 1 page.

Evaluation of the ” Sabana de Bogota” aquifer using isotopes techniques. Groundwater from the Sabana de Bogota area was studied by means of isotopic techniques such as isotope analysis, injection of tracers for determination of hydrogeological parameters, velocity measurements using tracers. These results combined with the ones obtained by conventional techniques were used to determine recharge area, origin, equipotencial lines and direction of groundwater.

The results show that a combined application posmoderniad classical and nuclear methods may establish rather reasonable hydrogeological concepts without investing much time and money. The Laguna de La Herrera alt. This part of the Sabana has a relatively dry climate appr. Mochima, estado Sucre Venezuela.
