New Technologies in Extrusion Process for Shrimp Feed por Muñoz, Osvaldo

“…This is why the feed must also generate lower levels of waste.It is well known that the extrusion process compared with the pelleting process, produce better nutritional quality feed, but in the particular case of shrimp, where a feed of high density and stable in the water is required, the extrusion by itself is not able to achieve these levels of desired density.The main characteristics of the shrimp feed are:- Water Stability, Digestibility, Quick sinking, Smaller size of the pellet, Reduces pollution in the water, - Lowering costs in the feed and OtherAlthough the extrusion process requires a highest investment and also the operational costs are higher than the pelleting process, if the extrusion process has the appropriate technology for densification, it would be much cheaper with a much greater profit than the pelleting process and most importantly, with a better quality feed as a result.In this work we show the latest technological advances in this direction to achieve a feed for shrimp in high quality and low cost through the extrusion process.…”

The social class struggles concept with an interdisciplinary approach: a paramount concept for research in library and information science (LIS) por Muela Meza, Zapopan Martín

“…This concept is complemented from philosophy (Marx and Engels, [1848] 1976a), and the natural sciences (Hauser, 2006; Sagan and Druyan, 1992), and it served the author to understand better the bigger dimensions of the underlying issues behind social classes and human conflicts. It also served to understand better the contradictions between people (e.g. …”
