Account of Non-Diagonal d-d-Electron Couplings in CoNi Liquid Alloy
The partial Wills-Harrison effective pair potentials in liquid equiatomic Co-Ni alloy are considered. It is shown that the account of the non-diagonal d-d couplings between electrons leads to similar changes in characteristics of the pair-potential first minimum as for Fe-Co and Fe-Ni equiatomic alloys.
Account of non-diagonal coupling between d electrons at describing the transition-metal pair potentials
In the framework of the Wills-Harrison (WH) model the correction due to the non-diagonal coupling between d electrons in different atoms is suggested. Effect of this correction on the WH effective pair interaction is studied for liquid Fe, Co, and Ni. It is found that our approach gives a shift of the WH pair potential to the right-hand side for all metals under consideration (in most degree for Fe and in less degree for Ni). As a rule, such tendency leads to significant changes in calculating thermodynamic properties.
The Alzheimer's Disease Home Hospice Knowledge Scale: development, validity and reliability.
BACKGROUND
Several instruments are available to assess knowledge about hospice care, but none specifically address knowledge about home hospice for persons with Alzheimer's disease (AD).


AIM
To develop and validate the Alzheimer's Disease Home Hospice Knowledge Scale (AD-HHK-S).


METHODS
A total of 107 Israeli family caregivers of persons with dementia (mean age=71.2; 73% female) participated in the study.


RESULTS
The AD-HHK-S included 28 true/false items assessing 3 areas of knowledge: knowledge about hospice, knowledge about home hospice, and knowledge about home hospice for AD. Good internal reliability was found, with Cronbach alpha ranging from 0.72 to 0.85. Good face, construct and predictive validity were found.


CONCLUSIONS
The AD-HHK-S proved to be a valid and reliable tool to assess knowledge about hospice care in the area of AD. It might provide an effective tool for palliative care nurses to communicate with family caregivers of persons with AD at the end of life.
