Hardness Depth

The effects of small amount (1 or 2 wt.%) of Ni additionson the irradiation hardening of the reduced-activation ferritic/martensitic steel, F82H, used as fusion reactor blanket structural materials were investigated by means of Fe-ion irradiation experimental test method and nano-indentation technique. The ion-irradiation hardening of Ni-added F82H is larger than that of the steel without Ni addition. The methodology to derive the irradiation hardening of ion-irradiated F82H steel was proposed from the results of hardness depth profile.

First Time

The irradiation hardening behavior in a commercial ferritic/martensitic steel P92 has been investigated through 250KeV Ar-ions irradiations to a dose of 10dpa at 473, 673 and 973K combined with nanoindentation techniques. The results show that irradiation-induced hardening was observed at the all irradiation temperatures. There appear to have no previous reports of the irradiation-induced hardening at the temperature higher than 873K in ferritic/martensitic steels. Irradiation-induced hardening at elevated temperature of 973K has been found, for the first time, in ferritic/martensitic steel. The irradiation-induced hardening at 973K in the ferritic/martensitic steel P92 may be ascribed to the defects in the steel generated by Ar-ions irradiation.

Traditional Medical Model

Purpose Person-centered care shifts the focus of treatment away from the traditional medical model and moves toward personal choice and autonomy for people receiving health services. Older adults remain a priority for person-centered care because they are more likely to have complex care needs than younger individuals. Even more specifically, the assessment and treatment of swallowing disorders are often thought of in terms of setting-specific (i.e., acute care, skilled nursing, home health, etc.), but the management of dysphagia in older adults should be considered as a continuum of care from the intensive care unit to the outpatient multidisciplinary clinic. In order to establish a framework for the management of swallowing in older adults, clinicians must work collaboratively with a multidisciplinary team using current evidence to guide clinical practice. Private practitioners must think critically not only about the interplay between the components of the evidence-based practice treatment triad but also about the broader impact of dysphagia on caregivers and families. The physical health and quality of life of both the caregiver and the person receiving care are interdependent. Conclusion Effective treatment includes consideration of not only the patient but also others, as caregivers play an important role in the recovery process of the patient with swallowing disorders.
