The health of family carers may affect not only their own lives but also the lives of the people for whom they provide care. This article describes how the caring role can affect the health and well-being of a carer of a person who has a mental or physical disorder. Suggestions are made about how to recognise and ameliorate some of the detrimental effects of the caring role on the carer's own health.
cw power conversion efficiencies of 57% have been obtained on uncoated diode lasers emitting nearly 300 mW per facet. This performance is achieved by using a low-resistance graded index separate confinement single quantum well AlGaAs/GaAs structure with high (84%) differential quantum efficiency and low threshold current.
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.
