Electrical Properties, Tunability and Applications of Superconducting Metal-Mixed Polymers

Andrew Stephenson Unknown Date (has links)
We investigate the newly discovered, superconducting metal-mixed polymers made by embedding a surface layer of metal (a tin-antimony alloy) into a plastic substrate (polyetheretherketone - PEEK). Focusing initially on pre-implanted systems, we show that while the substrate morphology does affect the distribution of metal deposited on the surface, the morphology has no affect on the film's electrical properties. We find that the metal content can be characterised via the film's optical absorption, which along with the conductivity, scales with thickness. By conducting low temperature resistivity measurements we observe that the superconducting critical temperature, $T_c$, remains at that of bulk Sn but the transition broadens with decreasing film thickness. Studying N-implanted metal-mixed polymers, we find that the implant temperature can influence the electrical properties of these systems, as higher implant temperatures result in greater disorder, which in turn causes higher residual resistances and broader superconducting transitions. We observe peaks in the magnetoresistance of superconducting/insulating systems, which we attribute to the competition between superconductivity and weak localisation in a granular network. We determine that the substrate morphology does not influence the electrical properties of implanted systems. We investigate the role sputtering plays by implanting heavier ions (Sn) and show that this technique can be used to overcome the issue of inhomogeneity inherent with using thinner initial films. We study the effect the fabrication parameters of implant dose, beam energy and film thickness have on Sn-implanted metal-mixed polymers and find that with only minor changes in the fabrication conditions, it is possible to tune the conductivities of these materials between a zero-resistance superconducting state, through a metal-insulator transition, to a severely insulating state ($R_s > 10^{10}~\Omega/\Box$). We find that the electrical properties can be further controlled by annealing the samples, and that it is possible to induce optical changes at temperatures approaching the glass transition temperature of PEEK. We demonstrate that metal-mixed polymers are suitable for use in resistance-based temperature sensors by comparing their performance directly against commercially available products and find that the metal-mixed polymers perform at least as well as the commercial models and, indeed, pass the highest industry standards.

Temperature Recording of Pregnant Women in Labor: Analysis of Two Non-invasive Thermometers

Longcoy, Joshua, Elkattah, Rayan, Foulk, Brooke, Zheng, Shimin, Alamian, Arsham 02 April 2014 (has links)
The objective of this study is to compare two non-invasive thermometer technologies in pregnant women admitted for labor at the Family Birthing Center in Johnson City Medical Center. A total of 50 patients were recruited in the study. Temperature measurements using the oral 3M® Tempa.Dot and the Exergen 5000 Temporal Artery Thermometer (TAT) were obtained by trained personnel. These recordings were obtained once upon admission, at 2-hour intervals until delivery (to a maximal time of 20 hours), 1 hour before and after epidural placement, and 2 hours after vaginal delivery. The temperatures readings were then compared over all time points, and at each time point using SPSS and Student paired t-test. Trends of temperature changes in labor between both thermometers were also evaluated. We noted that over all time points, the skin temperature was 0.38°F higher than the oral temperature. This difference was statistically significant as well (98.19°F ±0.681 vs. 97.81°F ±0.750, p

Deprese, úzkost a kvalita života u dospělých pacientů po popáleninovém traumatu / Depression, anxiety and quality of life in adult patients after burn injury

Sedláčková, Thea January 2021 (has links)
The diploma thesisfocuseson the issue of depression,anxiety and quality of life in adult patients after burn trauma. The literature review section presents current scientific studies that apply to the diagnosis,prevalence,treatmentand selectedrisk factorsfordepressionand anxiety in this patient population. This part of the thesis also deals with the definition and methodsof assessing the quality of life in patients with burns, including factors that may affect the subjectively perceived quality of life in this population. The empirical part aims to identify patients with MDE and GAD according to M.I.N.I. and to examine risk factors not only for these mental disorders but also for reduced quality of life. Furthermore, the research focuses on the validation of the visual analog screening method of Emotional Thermometers in patients after burn trauma. A total of 292 hospitalized patients with burns participated in the study, of which 27 (9 %) met the diagnostic criteria for MDE (current, past, recurrent). 10 patients (3.5 %) met the diagnostic criteria of GAD. Statistically significant predictors of MDE are: antidepressant use and surprisingly a lower extent of burns. The use of antidepressants and unexpectedly a less frequent occurrence of burns in visible places of body (head, neck, upper limbs)...

No. of bitstreams: 1 Roberta Neves.pdf: 2013363 bytes, checksum: 02dd0656ebbb2438dc6715d64f374fdb (MD5) Previous issue date: 2014 / Mestrado Profissional em Enfermagem Assistencial / O estudo aborda os processos de limpeza e desinfecção dos principais dispositivos de monitoramento não críticos (termômetros, esfigmomanômetro, cabos de eletrocardiograma e oxímetro) considerando a sua participação na transmissão das infecções relacionadas à assistência à saúde. Estes equipamentos têm sido apontados como uma das principais fontes de infecção por bactérias multirresistentes causadoras de surtos infecciosos em ambiente hospitalar portanto, exigem padronização da limpeza e desinfecção, mediante um protocolo que norteie o processo de trabalho. Este estudo teve como objetivos: elaborar um protocolo de limpeza/desinfecção dos principais dispositivos de monitoramento não críticos, com base nas boas práticas e evidências na literatura, e validar este protocolo com avaliação de experts em infecção hospitalar. Trata-se de estudo descritivo e exploratório, que no seu desenvolvimento seguiu as seguintes etapas: revisão integrativa da literatura, elaboração do protocolo de limpeza e desinfecção dos principais dispositivos de monitoramento não críticos e validação do protocolo por experts em infecção hospitalar. A elaboração do protocolo ocorreu a partir das boas práticas identificadas nos estudos selecionados na revisão integrativa, livros, teses, dissertações e documentos de órgãos nacionais e internacionais sobre a temática. Para validação do protocolo foram selecionados cinco experts em infecção hospitalar, de acordo com os critérios de seleção sugeridos no estudo. Após avaliação de cada recomendação do protocolo proposto, em um questionário, foi calculado o grau de concordância entre eles por média ponderada. A partir da análise dos registros dos experts e, considerando o grau de concordância das respostas, foi elaborado o protocolo final. Assim, respondendo aos objetivos do estudo, inicialmente tem-se o protocolo construído a luz do conhecimento científico que foi chancelado por um grupo de experts gerando o protocolo final. Este protocolo é portanto, o produto desta pesquisa e com ele pretende-se padronizar os processos de limpeza e desinfecção destes dispositivos, visando preencher as lacunas do conhecimento teórico/prático identificadas sobre a temática e reduzir os riscos de transmissão de infecção por estes artigos. Este protocolo será proposto à Comissão de Controle de Infecção Hospitalar da Secretaria Estadual de Saúde do Rio de Janeiro, a fim de implementá-lo nas unidades de pronto atendimento 24 horas (UPAs 24hs) testando sua aplicabilidade e futuramente sua eficácia. / The study discusses the procedures of cleaning and disinfection of the main non-critical monitoring devices (thermometers, sphygmomanometer, electrocardiography wires and oximeters wires) considering their participation in the transmission of infections related with health care. These equipments have been identified as the major source of infection by multiresistant bacteria that causes hospital infections, therefore, require standardization of cleaning and disinfection, by using a protocol that guides the work process. This study aims to: develops a protocol for cleaning / disinfection of the main non-critical monitoring devices, based on best practices and evidence in the literature, and validate this protocol with assessment of experts in hospital infections. It is descriptive and exploratory study, which involved the following steps: integrative literature review, development of the protocol for cleaning and disinfection of the main devices of non-critical monitoring and a validation of this protocol by the experts of hospital infection. The protocol development is based on best practices identified in the studies selected in integrative review, books, thesis, dissertations and national and international documents on the subject. To validate the protocol, five experts in hospital infection were selected according to the selection criteria suggested in the study. After evaluating each recommendation of the proposed protocol, in a questionnaire, the degree of agreement was calculated by weighted average. From the analysis of the observations of experts and considering the degree of agreement of answers, a final protocol was developed. So, to answer the aim of this work, first of all, a protocol was developed with scientific knowledge and afterward judged by some experts, which leads to a final protocol. Therefore this final protocol is the result of this study and it is intended to standardize the process of cleaning and disinfection of these devices, fill gaps in theoretical/practical knowledge on the subject and reduce the risk of infection transmission by these objects. These protocol will be proposed to the of Hospital Infection Control Committee at the State Department Health of Rio de Janeiro, to implement it in emergency care unit (called “UPAs 24 hs”) testing its applicability and future effectiveness.
