For validation, a linear transducer (T-Force System Ergotech, Murcia, Spain) and videography analysis (SkillSpector version 1.3.2) were used. Participants developed the flat bench press in a SMITH machine. The protocol consisted of a repetition of flat bench press with a constant load (18 kg). Recovery between repetition was 15 seconds. In total 5 subjects developed 84 repetitions. The data were characterized by a minor difference between the values of the mean of the Wireless vs T-Force device (0.18) in contrast to Wireless vs. Videography (0.46). The results show that there are no statistically significant differences in the acceleration of displacement between the Wireless device, linear transducer and videography analysis; however, the reported Pearson correlation levels showed a moderate association (p <0.05) for the two tests. The assumption of independence of the errors was proven by the Durbin-Watson test. The results suggest that, although there were no high associations between the devices, the economic component of the production of the Wireless device makes it a viable alternative for the control and measurement of acceleration in sports.","PeriodicalId":30271,"journal":{"name":"Ingenierias USBMed","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45013039","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}

Materials and methods: exploratory - descriptive, purposeful study. For the design, a documentary review of qualitative and quantitative scientific research articles was carried out, in English, Spanish, they were consulted in sources of biomedical information with words from specialized thesauri such as MEsH and DeCS, they were consulted in databases: PubMed, Scielo, IEEE, among others. The search expressions were: Electromyography, uterine muscle and protocol. No specific protocols for uterine electrohysterography were found, which is why the publications referring to electromyography protocols in general were taken, finding a total of 193 publications, of which 23 articles were selected, published between the years 2012 to 2020. For the analysis the research method called integrative review was used. Results. The protocol establishes the criteria that must be taken into account before and during the procedure, the equipment and materials required, and contraindications, to capture the record of electrohysterographic signals. Conclusion. Health care protocols are fundamental since they standardize the processes that must be followed in capturing signals, minimizing possible complications during and after the procedure, to the benefit of the mother-pair son.","PeriodicalId":30271,"journal":{"name":"Ingenierias USBMed","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-05-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46415856","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 pesar de ello, estos materiales presentan desventajas como la sensibilidad de la película de perovskita a la humedad del ambiente, lo que resulta un tiempo de vida de los dispositivos corto. Una alternativa para estabilizar la celda es la aplicación de aditivos, los cuales son líquidos iónicos formados por un catión y un anión con un carácter altamente hidrófobo, basados en fosfonio (tetraburoborato de tetrabutil fosfonio(B4PBF4).
