TiO2 nanotubes for room temperature toluene sensor

TiO2 nanotubes were used to prepare gas sensor and the gas sensing properties towards toluene were analyzed. Titania nanotube arrays were fabricated via electrochemical anodization method in glycerol electrolytes containing NH4F. The sensor fabricated from these nanotubes exhibits a good response to toluene at room temperature with good sensitivity. The toluene sensing properties were tested from 20 to 150 ppm concentrations.Fil: Perillo, Patricia Maria. Comisión Nacional de Energía Atómica.

PATIENT ENGAGEMENT:THE FACTORS CONTRIBUTING TO INDIVIDUALS USING THE PATIENT PORTAL

The patient portal is an electronic repository of health information, including doctor’s notes, laboratory test results, and diagnostic imaging reports. There are limited studies that explore how individuals make sense of their health information, and use that understanding to increase health literacy. Education leaders should consider the ways that students in allied health care fields might better understand the role of the portal, the federal investment in developing electronic records, and the perceived value of the portal by patients. The purpose of this study was to explore portal usage among employees at Suffolk County Community College, individuals’ experience with the health care environment, the individuals’ understanding of health information, and how these influence the individuals to become a more active participant in their own health care. To do so, this quantitative study examined the relationship between individual attributes, including health status, and education level that may determine a patient\u27s perceived value of the portal as measured by portal usage. Factors measured include individual beliefs that a patient can master the portal, the environment that supports the individuals, and their health literacy. The participants of the survey study were individuals employed by Suffolk County Community College. A twenty item self-reported questionnaire measured key variables in the study. Section one of the instrument including independent variables, demographic characteristics, health literacy, education level, and health status. The dependent variable is patient portal usage. A multiple linear regression analysis was conducted to test the null hypothesis to determine if health literacy, education level, and health status can predict portal usage. A Pearson’s correlation was used to examine the relationship between health literacy and portal usage, education level and portal usage, and health status and portal usage. An independent-samples t-test was conducted to compare portal usage with health status, specifically for major and minor health issues. Descriptive statistics also provided information for consideration. The findings support previous literature that indicates health status and health literacy are significant predictors of portal usage, and provide considerations for educational leaders in allied health

Obesidad como factor de riesgo de infección del tracto urinario en niñas febriles menores de 5 años en el Hospital Belén de Trujillo

Determinar si la obesidad es un factor de riesgo de infección del tracto urinario en niñas febriles menores de 5 años del Hospital Belén de Trujillo en el periodo enero del 2016 - octubre del 2019. Material y métodos: Se llevó a cabo un estudio de tipo retrospectivo, analítico de casos y controles en el que se incluyeron a 192 niñas menores de 5 años, según criterios de selección los cuales se dividieron en 2 grupos: el primero con 96 niñas con infección del tracto urinario y el segundo con 96 sin infección del tracto urinario, en los que se determina la prevalencia de obesidad. Resultados: No se apreciaron diferencias significativas entre las variables edad, lactancia materna no exclusiva y grado de instrucción materno entre las pacientes con o sin infección del tracto urinario. Proporción de obesidad en niñas febriles menores de 5 años con infección del tracto urinario fue de 27%. Proporción de obesidad en niñas febriles menores de 5 años sin infección del tracto urinario fue de 15%. La obesidad es factor de riesgo para infección del tracto urinario en niñas febriles menores de 5 años con un odds ratio de 2.17 (p<0.05). Conclusión: La obesidad es un factor de riesgo de infección del tracto urinario en niñas febriles menores de 5 años del Hospital Belén de Trujillo en el periodo enero del 2016 - octubre del 2019.To determine if obesity is a risk factor for urinary tract infection in febrile girls under 5 years of age at Belén de Trujillo Hospital the interval January 2016 - October 2019.

Two-stage quality monitoring of a laser welding process using machine learning – An approach for fast yet precise quality monitoring

In production, quality monitoring is essential to detect defective elements. State-of-the-art approaches are single-sensor systems (SSS) and multi-sensor systems (MSS). Yet, these approaches might not be suitable: Nowadays, one component may comprise several hundred meters of the weld seam, necessitating high-speed welding to produce enough components. To detect as many defects as possible in time, fast yet precise monitoring is required. However, information captured by SSS might not be sufficient and MSS suffer from long inference times. Therefore, we present a confidence-based cascaded system (CS). The key idea of the CS is that not all data are analyzed to obtain the quality weld, but only selected ones. As evidenced by our results, all CS outperform SSS in terms of accuracy and inference time. Further, compared to MSS, the CS has hardware advantages

Fragmentierte Solidarität: das Ende des organischen Zusammenhaltes durch subjektivierte Erwerbsarbeit

In diesem Beitrag soll das Verhältnis von Solidarität und Subjektivierung in Bezug auf Erwerbsarbeit in den Blick genommen werden. Für die gesellschaftliche Entwicklung ist Arbeit zentral, da die Formen, in denen Menschen diese leisten und vollbringen, maßgeblich in Wechselwirkung zu ihren Lebensbedingungen stehen. Die Herausbildung der modernen Arbeitsformen in kapitalistisch organisierten Wirtschaftssystemen im 19. und 20. Jahrhundert ist dabei durch Kollektivierung geprägt gewesen. Bis in die 1990er galt "Solidarität" als grundlegendes Scharnier arbeitsweltlicher Ordnung, in der Folgezeit entwickeln sich Individualisierung und "Subjektivierung" zu Phänomenen, welche die Arbeitswelt in vielerlei Hinsichten überlagern und verändern. Auf der Suche nach den zukünftigen Formen von Arbeit ist so bspw. der "Arbeitskraftunternehmer" bekannt geworden. Solidarische Einstellungen verschwinden jedoch auch mit dem Übergang zur Wissensgesellschaft, in der subjektivierte Formen von Erwerbsarbeit dominieren, nicht. Solidarität in einer durch subjektivierte Wissensarbeit geprägten Erwerbsgesellschaft nimmt aber eine neue Form an, die im Beitrag als subjektivierte Solidarität bezeichnet wird.In this paper, the relationship of solidarity and subjectification in matters of employ-ment is examined. Employment can be regarded as a main element for the develop-ment of societies since the forms, in which people work, significantly affect their living conditions. The development of modern forms of employment in capitalist economies in the 19th and 20th century has been influenced by collectivity and solidarity. Up to the 1990s solidarity can be regarded as a main mechanism of the arrangement of work and employment. In the following years, individualization and "subjectivication" ("Subjektivierung") have become phenomena that changed the employment relationship and working conditions in many ways. In the search of future forms of employment, the "entreployee" ("Arbeitskraftunternehmer") has experienced a lot of attention. In the transition towards a knowledge-based society (in which subjectificated forms of work are dominating) solidarity between working people does not become redundant. Instead, solidarity in such a working society will turn into new forms. In this paper, we call this subjectificated solidarity (subjektivierte Solidarität)
