The present work seeks to present viable and economical alternatives for teaching laboratories to investigate chemical deposition processes in aqueous solutions and produce thin layers of materials of interest in solid-state chemistry and new materials. The metals studied were copper, cobalt and, nickel in different types of salts and reducing agents, hydrazine hydrochloride, phenylhydrazine and, sodium borohydride. The main results show that it is possible to use cheaper chemicals to study depositions in an aqueous solution, a viable alternative for laboratories.","PeriodicalId":18592,"journal":{"name":"Minerva endocrinologica","volume":"45 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88308761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to analyze the continuous training of mathematics teachers and its relationship with pedagogical practice. The applied methodology was a non-experimental design with a mixed approach and a systematic literature review. Therefore, the techniques used were the survey and the focus group. A conventional population of teachers and vice-chancellors of the different educational units of Quevedo was selected as an object of study. According to the results in the last two years, the number of training carried out by teachers is negligible, ranging from 1 to 5. Consequently, the requirement of the courses is dissimilar.","PeriodicalId":18592,"journal":{"name":"Minerva endocrinologica","volume":"356 1","pages":""},"PeriodicalIF":4.1,"publicationDate":"2023-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77150615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In analyzing the primality of a particular term, the divisions by factor 3 are excluded.

Los ensayos se valoran de forma sencilla, y se han ejecutado en 180 probetas, del mismo material, proveniente del sector Cojitambo, provincia del Cañar (Ecuador). Los resultados permiten su caracterización, estableciendo que la resistencia a compresión varía entre 75.9 MPa y 124.8 MPa, lo que categoriza al material como roca dura.
