Aims and objectives: To explore the role of resilience in anxiety and depression and to clarify their relationships among patients with mild symptoms of coronavirus disease 2019 (COVID-19) in Wuhan, China. Background: The outbreak of COVID-19 has negatively affected some individuals, but resilience plays a decisive role in the response of individuals under pressure and can help them deal with pressure more effectively. Design: The cross-sectional descriptive correlational survey was reported in line with the STROBE guidelines. Subject and setting: In total, 296 patients from FangCang Hospital in Wuhan, Hubei, China, with mild symptoms of COVID-19 were recruited. Methods: Participants were recruited through convenience sampling. The data collected included their demographic information, the Connor-Davidson Resilience Scale and Hospital Anxiety and Depression Scale. Results: A small number of patients in this study had above threshold anxiety (subthreshold anxiety and major anxiety) and depression (subthreshold depression and major depression). The mean total resilience score of the participants was slightly below the normal level of ordinary Chinese adults. Resilience was inversely associated with and was a protective factor for both anxiety and depression in our samples. Risk factors for anxiety include being female and having colleagues with COVID-19, while a risk factor for depression was having family members with COVID-19. Conclusions: This study shows that after taking the general demographics into consideration, higher levels of resilience were associated with lower anxiety and depression among mild COVID-19 patients in Wuhan, China. Relevance to clinical practice: Health professionals, especially clinical nurses, need to be aware of the psychological status of COVID-19 patients and promote resilience to improve their mental health. | 4021 ZHANG et Al.
Alkanes and their mixtures (paraffins) have widely been used as phase change materials (PCMs) for low-tomedium temperature thermal energy storage. Among the various alkanes, eicosane, with a nominal melting temperature of 37 °C, has emerged in energy-storage-based passive thermal management technologies, for electronics for example. In an effort to increase the thermal conductivity of eicosane, the effect of adding graphene nanoplatelets (GNPs) as thermally conductive nanofillers was investigated experimentally. The composite PCM samples were prepared by dispersing GNPs in liquid eicosane at various loadings (0, 1, 2, 5, and 10 wt.%) without any surfactants. Thermal conductivity of the composite PCM samples in their solid phase was then measured by means of the transient plane source technique at elevated temperatures from 10 to 35 °C. Latent heat of fusion and melting point of the samples were also characterized using a differential scanning calorimeter. It was shown that for the highest loading examined (10 wt.%), the relative thermal conductivity enhancement is above 400% at 10 °C, indicating that the emerging GNPs have much better performance than the conventional nanofillers attempted in the available literature, such as metal/oxide nanoparticles and carbon nanotubes. Reduced thermal interface resistance, related to the unique two-dimensional planar morphology of GNPs, was interpreted to be responsible for their superior performance. The matrix/filler thermal interface resistance was estimated to range from 6 × 10 −9 to 9 × 10 −9 m 2 K/W. In contrast to the markedly increased thermal conductivity, however, the penalty of decrease in the energy storage capacity, caused by the presence of GNPs, was shown to be less significant.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
