Characterization allowed evaluating the effect of Sm3+ insertion on thestructural, morphological and magnetic properties of the bismuth ferrite. Structural characterization was made by X-rayDiffraction (XRD) and Rietveld refinement, indicating the formation of a rhombohedral majority phase of the space groupR3c (161) with a proportion higher than the reported up to now. The morphological characterization through scanning electron microscopy (SEM) allowed concluding that the insertion of samarium decreases the particle size from 7.5 μm to 2.5 μm, thanks to the smaller ionic radius, which also led to the contraction of the lattice parameters. The magnetic analysis showed a typical ferromagnetic behaviour in all of the synthesized samples, with the presence of a PM-AFM transition at 260 K.","PeriodicalId":31506,"journal":{"name":"Ingenieria Investigacion y Desarrollo","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43950305","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}

Esto se debe a la desconfianza que existe en la población acerca de la calidad del agua de grifo y el acceso es igual e intermitente a los sistemas de agua potable. La contaminación del agua embotellada por bacterias se ha reportado alrededor del mundo, pero no se ha investigado la presencia de otros microorganismos, como las amibas de vida libre patógenas, que pueden estar en el ambiente, pero también pueden causar infecciones en el humano. El objetivo de la presente investigación fue determinar la presencia de las amibas de vida libre patógenas en agua embotellada. Se analizó el agua de 47 garrafones de 20 litrosque se venden en el Área Metropolitana de la Ciudad de México. Se analizaron 2 muestras de cada garrafón, una al abrirlo y otra a la mitad del volumen. Las amibas se determinaron por cultivo en el medio agar no nutritivo y se identificaron por morfología. Treinta y un garrafones fueron positivos para la presencia de las amibas, de estos 21 fueron de purificadoras locales y 10 de purificadoras grandes. Se encontraron 15 especies de amibas, la mayoría de ellas no son patógenas, solamente del del género Acanthamoeba han reportado como patógenas oportunistas, lo que representa un riesgo para la salud de las personas con defensas bajas. Por lo que además de la calidad bacteriológica y fisicoquímica, también sedebería de tomar en cuenta la calidad amebológica del agua embotellada.","PeriodicalId":31506,"journal":{"name":"Ingenieria Investigacion y Desarrollo","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49269636","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}

Yard waste may represent a problem to Municipal Solid Waste Management Programs due to its large volume thus, it is necessary to incentivize local composting programs. In this study we show a brief disposal cost estimation from different cities from United States of America and Canada and we discuss how this biowaste can be managed in order to reduce costs with storage, transportation and disposal fees, encouraging the utilization of the final product as a soil amendment, stimulating and reinforcing the circular economy concept. The composted yard waste may not substitute the use of commercial products but it can reduce the cost of acquisition of this soil conditioner as well costs waste management. Update in environmental public policies is essential to foment sustainable economy in this context.","PeriodicalId":31506,"journal":{"name":"Ingenieria Investigacion y Desarrollo","volume":"41 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88790541","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}

For this purpose, the performance of the natural tannin coagulant in relation to the inorganic coagulants of polyaluminium chloride (PAC) and ferric chloride was analyzed. The parameters studied were related to the removal of apparent color, turbidity and COD. The bench scale treatment consisted of the physical-chemical processes of coagulation, flocculation and sedimentation, and the determination of the amount of tests required and the processing of the results obtained were carried out using the Statistica software. The test variables were the coagulant dosages and the coagulation pH, and after the discovery of the ideal treatment, the performance of the tannin coagulant in relation to the removal of phosphorus, nitrogen, suspended solids and total solids, as well as changes in conductivity and alkalinity were also verified. All coagulants reached results of removing turbidity, apparent color and COD above 97%, with emphasis on tannin, which in addition to exceeding 99%, facilitates the disposal of sludge, as it is a biodegradable coagulant.","PeriodicalId":31506,"journal":{"name":"Ingenieria Investigacion y Desarrollo","volume":"744 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76841133","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}
