Se evaluó un sistema de centrifugación con tela filtrante con el objeto de analizar una alternativa que permita reducir el tiempo de tratamiento, costo y buscar obtener beneficios ambientales para el sector curtidor. Los materiales filtrantes fueron 5 tipos de telas (cambre, madre selva, jean, militar y gladiador) y se determinó que la resistencia a la filtración que ofrece cada material no es significativa, por otra parte, el lodo producto del tratamiento de agua residuales de pelambre ofrece alta resistencia a la separación sólido/agua (r= 7,0179E+13 s²/kg) y por lo tanto un bajo alcance de filtración (Y= 0,000413 kg/m²*h), hecho que hace que un sistema de centrifugación para este tipo de lodo requiera de una considerable área y alto consumo energético. \u0000 ","PeriodicalId":33457,"journal":{"name":"Revista Vinculos","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46873678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A way to achieve these goals is by the substitution of fossil fuels with biofuels. This study compares three Andean countries: Colombia, Ecuador and Peru, in terms of bioethanol blending mandates current scenario and its sustainability. For this analysis, a review of the state of the art of first and second generation bioethanol in the three countries were developed, including a social network analysis to understand the interactions that have enhanced or delayed the achievement of their blending objectives as countries. So far, Colombia is near to reach its blending target; Ecuador has recorded a bioethanol deficit, estimated at 75%; and regarding Peru, in the last years they have achieved their national target. In addition to blending mandates, the countries appear not to rely on a sustainability policy for the development of first or second generation bioethanol. Furthermore, these Andean countries are planning to increase their blending targets. In order to achieve this, political efforts must be focused on feedstock availability as well as on the development of guidelines related to sustainability and technologies to be applied in their own context.","PeriodicalId":33457,"journal":{"name":"Revista Vinculos","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42096429","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This analysis is important to identify which are the areas that present greater deterioration, considering that the bones lose their property of self-recovery over the years increasing the probability of presenting a fracture, having this information clear the prosthetic studies and medical treatments focused on the femur can be deepened. In this analysis, it can be identified that the male femur has greater resistance to tension and deformation than the female femur and how the femoral head is the most critical area of both the female and male fêmur.","PeriodicalId":33457,"journal":{"name":"Revista Vinculos","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46194474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
