Consideraciones críticas sobre el prestigio y la diginidad personal y profesional de los bibliotecarios por Torres Reyes, José Antonio

“…As for the library guild activities, it criticises the demogogical charlatanism and opportunism of guilds such as AMBAC (standing from the Mexico-wide Mexican Library Association, Nuevo Leon chapter), where their leaders only take advantage of the ineptitudes of the three levels of the Mexican government (municipal, state, and federal) on library issues, and they use the natural disasters against libraries or librarians by appealing to people’s sentimentalisms just to appear themselves in the picture and in the press, but without analysing, criticising and denouncing the deep structural faults underneath the Mexican State, and from all the three levels of the Mexican governments.…”

The Use of Concentrates and Other Soy Products in Shrimp Feeds por P Forster, Ian, Dominy, Warren, G.J. Tacon, Albert

“…Soy products have continued to be employed in a range aquaculture feeds, principallybecause they provide an acceptable source of amino acids at a very reasonable price.Advances in processing have led to the production of higher protein content soy products,namely soy protein concentrate (SPC) and protein isolate, which are manufactured byselective removal of carbohydrates. The protein level of these ingredients is similar to thatof standard fish meal, although there are some important differences in amino acid profile.This paper discusses the use of soy products, especially SPC, in aquaculture feeds, anddescribes work conducted with SPC in diets for Pacific white shrimp Litopenaeusvannamei.Two growth trials were conducted to ascertain the ability of SPC to replace fish meal inshrimp diets. …”
