Nursing Children and Young People is a nursing journal covering the practice of pediatric nursing. The journal was established in 1989 as Paediatric Nursing, obtaining its current title in 2014, and is published by RCN Publishing. It is abstracted and indexed in CINAHL, Embase, MEDLINE/PubMed, Scopus, ProQuest, EBSCO databases, and Thomson Gale.
A cycloconverter (CCV) or a cycloinverter converts a constant amplitude, constant frequency AC waveform to another AC waveform of a lower frequency by synthesizing the output waveform from segments of the AC supply without an intermediate DC link (Dorf 1993, pp. 2241–2243 and Lander 1993, p. 181). There are two main types of CCVs, circulating ...
A cycloconverter is also a type of frequency changer. Unlike a VFD, which is an indirect frequency changer since it uses an AC-DC stage and then a DC-AC stage, a cycloconverter is a direct frequency changer because it uses no intermediate stages. Another application is in the aerospace and airline industries. Often airplanes use 400 Hz power so ...
Children make up close to half the population in many African countries, but research suggests that children's nurses often make up less than 1% of the nursing workforce: a 2019 workforce survey found approximately 4,000 qualified children's nurses in South Africa, Uganda, Zambia, Malawi and Kenya. The majority (8/10) were in South Africa. [15]
Nursing Times was opposed to the lowering of the age for nurse training from 18 to 17, because it would ‘merely give rise to further exploitation of young people’ said an editorial in 1964. Nursing Times inadvertently provided a good opportunity to examine the issue of nursing administration that same year.
The tap converter is a variation on the cycloconverter, invented in 1981 by New York City electrical engineer Melvin Sandler and significantly functionally enhanced in 1982 through 1984 by graduate students Mariusz Wrzesniewski, Bruce David Wilner, and Eddie Fung.
A cycloconverter constructs an output, variable-frequency, approximately sinusoid waveform by switching segments of the input waveform to the output; there is no intermediate DC link. With switching elements such as SCRs, the output frequency must be lower than the input.
Nursing theories frame, explain or define the practice of nursing. Roy's model sees the individual as a set of interrelated systems (biological, psychological and social). The individual strives to maintain a balance between these systems and the outside world, but there is no absolute level of balance.
