Impact of Uniaxial Pressure on Structural and Magnetic Phase Transitions in Electron-Doped Iron Pnictides
We use neutron resonance spin echo and Larmor diffraction to study the effect
of uniaxial pressure on the tetragonal-to-orthorhombic structural () and
antiferromagnetic (AF) phase transitions in iron pnictides
BaFeNiAs (), SrFeNiAs,
and BaFe(AsP). In antiferromagnetically ordered
BaFeNiAs and SrFeNiAs with and
(), a uniaxial pressure necessary to detwin the sample also
increases , smears out the structural transition, and induces an
orthorhombic lattice distortion at all temperatures. By comparing temperature
and doping dependence of the pressure induced lattice parameter changes with
the elastoresistance and nematic susceptibility obtained from transport and
ultrasonic measurements, we conclude that the in-plane resistivity anisotropy
found in the paramagnetic state of electron underdoped iron pnictides depends
sensitively on the nature of the magnetic phase transition and a strong
coupling between the uniaxial pressure induced lattice distortion and
electronic nematic susceptibility.Comment: 18 pages, 15 figure
Negotiating The Maze: Confronting Dysphagia Together With My Stroke-Afflicted Family Member
Aim: To generate a descriptive theory grounded in the responses of family caregivers caring for their family stroke survivors with dysphagia during hospitalization. Design and Method: A qualitative study employing the grounded theory method was used. Fifteen family caregivers participated in comprehensive interviews. The interview data were analyzed using the constant comparative method. Findings: âNegotiating the maze: Confronting dysphagia with my stroke-afflicted family memberâ was the core category guiding the care process for dysphagia family members among caregivers. After surviving stroke, the caregivers felt âmore confusion less rejoicingâ as the antecedent condition. The following three interaction categories were identified: (1) âbeing overwhelmed by nasogastric (NG) tube issuesâ; (2) âsearching for the right helper and informationâ; and (3) âfood culture conflicts with the formula diet administered through the NG tubeâ. Additionally, âMaintaining positivityâ described the consequence of this process. Conclusions: This study highlights the critical perspective of family members who care for dysphagia stroke survivors in the hospital. Participants were under tremendous pressure during the disease treatment process. However, all attempted to maintain a positive attitude and treasured the chance to accompany their family members. Clinical Relevance: These findings can assist health professionals in charting the effects of dysphagia and in understanding the problems and needs according to the subjective perspectives of family caregivers. They can also provide a necessary foundation for comprehensive care interventions for family caregivers of stroke survivors with dysphagia
Ecosystem-Driven Design of In-Home Terminals Based on Open Platform for the
AbstractâIn-home healthcare services based on the Internet-of-Things (IoT) have great business potentials. To turn it into reality, a business ecosystem should be established first. Technical solutions should therefore aim for a cooperative ecosystem by meeting the interoperability, security, and system integration requirements. In this paper, we propose an ecosystem-driven design strategy and apply it in the design of an open-platform-based in-home healthcare terminal. A cooperative business ecosystem is formulated by merging the traditiona
Engaging service users and carers in health and social care education: : challenges and opportunities in the Chinese Community
This is an accepted manuscript of an article published by Taylor & Francis Group in Social Work Education on 25 June 2010, available online at: http://dx.doi.org/10.1080/02615479.2010.491542.Service users' and carers' involvement in health and social care education has become a mainstream activity in Britain. However, members from black and minority ethnic communities (BME) remain under-represented in this area of participation. In this article, we will take the readers across the globe to explore the difficulties and opportunities of engaging such an under-represented group, the Chinese community. The journey will begin in Britain where barriers to engagement of service users and carers from the Chinese community will be discussed. We will then travel to Hong Kong, a cosmopolitan city, where successful engagement in work with Chinese service users and carers will be explored. Throughout the journey, we will highlight the importance of the consideration of cultural factors, particularly Confucian beliefs such as social harmony and collectivism, when working with Chinese people. We will also fully explore the issue of âtrustâ as a culturally laden concept in Chinese societies and its significance for successful engagement in work with Chinese service users and carers in different parts of the world.Peer reviewedFinal Accepted Versio
Host factors do not influence the colonization or infection by fluconazole resistant Candida species in hospitalized patients
Nosocomial yeast infections have significantly increased during the past two decades in industrialized countries, including Taiwan. This has been associated with the emergence of resistance to fluconazole and other antifungal drugs. The medical records of 88 patients, colonized or infected with Candida species, from nine of the 22 hospitals that provided clinical isolates to the Taiwan Surveillance of Antimicrobial Resistance of Yeasts (TSARY) program in 1999 were reviewed. A total of 35 patients contributed fluconazole resistant strains [minimum inhibitory concentrations (MICs) ⧠64 mg/l], while the remaining 53 patients contributed susceptible ones (MICs ⊠8 mg/l). Fluconazole resistance was more frequent among isolates of Candida tropicalis (46.5%) than either C. albicans (36.8%) or C. glabrata (30.8%). There was no significant difference in demographic characteristics or underlying diseases among patients contributing strains different in drug susceptibility
Sensitivity to Gravitational Waves from Compact Binary Coalescences Achieved during LIGO's Fifth and Virgo's First Science Run
We summarize the sensitivity achieved by the LIGO and Virgo gravitational
wave detectors for compact binary coalescence (CBC) searches during LIGO's
fifth science run and Virgo's first science run. We present noise spectral
density curves for each of the four detectors that operated during these
science runs which are representative of the typical performance achieved by
the detectors for CBC searches. These spectra are intended for release to the
public as a summary of detector performance for CBC searches during these
science runs.Comment: 12 pages, 5 figure
