Se analiza el comportamiento del material a utilizar mediante probetas combinando los refuerzos en diferentes capas y sometiendo posteriormente a ensayos de tracción, flexión e impacto bajo normas ASTM. En el diseño de la carrocería se usó software CAD que permite evaluarla bajo condiciones aerodinámicas reales y determinar la geometría más adecuada. Para el conformado de las piezas se aplicó estratificación manual, posteriormente se pulieron y pintaron las partes. Los resultados obtenidos fueron favorables debido a que el material presentó excelentes características mecánicas a los diferentes esfuerzos, reduciendo considerablemente la masa en un 41.95 %, con relación a la carrocería 2012 que sirvió como referencia, y que fue fabricada con fibra de vidrio y resina poliéster.","PeriodicalId":21335,"journal":{"name":"Revista Mexicana de Ingeniería Química","volume":"28 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79449005","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}

Accordingly, the VG010 betabaculovirus has been identified as an effective agent in controlling the hornworm Erinnyis ello. The development of a wettable powder formulation using VG010 as an active ingredient in a biopesticide must have a guaranteed efficacy. An analysis of the unit operations involved in the formulation was carried out using proper operating conditions and production equipment. The active ingredient and finished product characterization revealed the repeatability of variables among batches. The mixing and drying processes were evaluated using operational parameters such as the mixing index and drying kinetics. From this analysis, the most favorable mixing time and drying temperature were selected to obtain a homogeneous product and high insecticidal activity. Viral concentrations, pH of the liquid mixtures, and drying temperature were established as control parameters of the critical points.","PeriodicalId":21335,"journal":{"name":"Revista Mexicana de Ingeniería Química","volume":"238 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77628835","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}

Por separado, se adapto un lodo anaerobico a condiciones reductoras de sulfato y se activo un lodo aerobico. Una vez concluida la activacion de los lodos, se integro el sistema IAAB, compuesto por un reactor anaerobico reductor de sulfato (ASRr) y un reactor aerobio oxidante de sulfuro (ASOr), y se hizo funcionar con una solucion sintetica rica en sulfato. Se variaron tanto la tasa de carga organica (OLR) como la relacion DQO / SO 4 2- . Durante los 43 dias de adaptacion de la ASRr, un 1 COD / SO 4 2-La relacion causo un desplazamiento casi completo de la actividad metanogenica por la actividad reductora de sulfato. Las eficiencias de remocion en el sistema IAAB para DQO, sulfato y sulfuro producido fueron 90%, 60% y 99%, respectivamente. Al final de la operacion del sistema IAAB, el flujo de electrones se dirigio principalmente a la actividad sulfidogenica, que representa el 91%. Este estudio demuestra que un sistema biologico anaerobico / aerobico de dos pasos que opera a OLR alto puede usarse para la remocion de sulfato y materia organica de aguas residuales ricas en sulfato como una alternativa a los metodos convencionales.","PeriodicalId":21335,"journal":{"name":"Revista Mexicana de Ingeniería Química","volume":"50 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79857485","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 type of reactors comprise an aerobic tank (where the biochemical reactions take place) and a membrane tank (where the final filtration process occurs). Mathematical modeling of these systems is a practical tool for the design, control and optimization of wastewater treatment plants. Among the modeling approaches, there is no mathematical model that is specifically designed for membrane bioreactors, and that captures the hierarchical nature of these systems. In the present work, new mathematical models for mass and momentum transport are derived from the fundamental equations at the continuum level. With the use of the volume averaging method, effective medium models for both the aerobic and membrane tanks were developed. This modeling approach has the advantage that the coefficients involved in the model can be predicted from closure schemes, without representing a demanding computational effort. This deterministic model allows predicting the most favorable design and operating conditions. Additionally, numerical simulations of these models give rise to a better understanding of the involved mass transport mechanisms in the membrane tank, this is achieved through the prediction of the fluid velocity, and the dynamics of the total mass flux and the concentration at each point in the tank. The models derived here are valuable because they allow analyzing the effect of each (operational and/or design) parameter over the dynamics of long-chain fatty acids and oxygen concentrations.","PeriodicalId":21335,"journal":{"name":"Revista Mexicana de Ingeniería Química","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85126715","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}

There is an evident need for the creation of a Brazilian Regulatory Agency for the carbon market that acts transparently and according to international agreements. In this study, we analyzed Braskem's greenhouse gas emission reports from 2010 to 2018 regarding the production of green polyethylene or other actions related to depollution of the environment. Furthermore, we sought to investigate Braskem’s relationship with the ICO2 index of the Sao Paulo Stock Exchange, which takes into account the degree of efficiency of greenhouse gas emissions of each member in this indicator. We discussed how the Stock Exchange manipulates ICO2 values through their calculation methods. Companies that participate in the ICO2 market have competitive advantages over stakeholders, even though they have agreed to abide by the Sarbanes-Oxley Act, which requires transparency regarding how the reduction of greenhouse gases emission occurs. We concluded that the lack of transparency and the ICO2 calculation methods also created a new derivative through which companies listed in the ICO2 could profit and reduce the risk of losses.","PeriodicalId":21335,"journal":{"name":"Revista Mexicana de Ingeniería Química","volume":"21 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85556457","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}
