Also we evaluate garlic yield and possible health risks as resulting from the organic amendments and the wastewater use. We found that: a) different doses and types of amendments did not have any significant effects on soil fertility; b) chicken manure and soil before planting, had E. coli and Salmonella spp.; and c) crop yields were quite similar in all treatments, only treatments with 8 Mg ha-1 of both amendments (chicken manure and vermicompost) without N fertilized, were significantly higher than control in both garlic assays. These results are probably the consequence of heavily tilled soils and poor quality of irrigation water with high abundance of enteric bacteria and labile organic matter content. We conclude that to obtain beneficial effects on soil fertility from organic amendment application, wastewater treatment systems must be improved and tillage practices must be reduced.

Agr. 36(2):177-190. Ethanol is the liquid combustible that has become the most promising alternative substitute for gasoline because of the experience gained in its production, the possibility of mixing it with gasoline in different proportions, the possibility of using the existing gasoline distribution infrastructure, and the fact that major changes in engines are not required for its use. Lignocelluloses offer great potential as a biomass source for ethanol production, although their use still requires in-depth analysis with an objective and holistic focus that includes present and future technologic implications. The present article reviews current knowledge about the characteristics and sources of vegetable biomass, as well as the development and possibilities for obtaining ethanol from lignocellulosic sources.

Alcohol-dependent people are also stigmatized from a social point of view, a process that each one of them can come to terms with subjectively. The answer to that situation is linked to a risk of suffering anxiety and marginalisation and could engender self-excuse strategies; those strategies could prevent overcoming such dependency. Fieldwork is based on active observation in Therapy Groups in two biomedical public centres in Catalonia (Spain), along with interviews with alcohol-dependent people, both in prolonged abstinence scenarios and going through a recovery process, and with professionals working in those centres, in order to have a deeper understanding of the therapeutical practices with users undergoing treatment.

El síndrome de la borrachera seca es un conjunto de síntomas que ocurren conjuntamente y que constituyen una anormalidad. Dado que la anormalidad de las actitudes y conducta del alcohólico durante su carrera de bebedor es generalmente reconocida, la persistencia de los rasgos de carácter después de que el alcohólico deja de beber deben parecer igualmente anormales. En consecuencia, el término "borrachera seca" se refiere a la ausencia de un cambio favorable en las actitudes y conducta del alcohólico que no bebe. Se infiere, de esta falta de cambio, que el alcohólico (hombre o mujer) esta sufriendo de un malestar en su vida. El síndrome puede ocurrir en todos los alcohólicos, y prácticamente no hay duda respecto de la causa de ese malestar.
