PISA is a cyclical cross-sectional study, with data collections occurring every three years.
The initial phase contents in the surface layer and its changes during the thermochemical cyclical treatment were studied by SEM analysis, metallography and microhardness measurements.
To further study the cyclical behavior of HSR wireless network link quality, we utilize HMC to describe the introduced reference model.
To further study the cyclical behavior of HSR wireless networks link quality, how the PLR and RTT vary against time is shown in Fig. 3.
In particular, it would useful to articulate a micro-analysis of labour market dynamics with a macro one and study the cyclical sensitivity of labour flows given each national institutional setting9.
Between 1949 and 1954 he worked on a sequence of seven Good Friday poems, "Horae Canonicae", an encyclopaedic survey of geological, biological, cultural, and personal history, focused on the irreversible act of murder; the poem was also a study in cyclical and linear ideas of time.
While these stages are often depicted in a linear fashion, the conceptual framework presented in this study is cyclical and dynamic, as some researchers have proposed [ 22, 23].
In animal studies, such cyclical loading prompts cartilage cells to divide and replenish the tissue, he said, while noncyclical loading, or the continued application of force, with little on-and-off pulsation, can overload the cartilage, and cause more cells to die than are replaced.
Our studies of cyclical E treatment in ovariectomized (OVX) young and aged rhesus monkeys have revealed compelling cognitive and synaptic effects of E in the context of aging.
Studies on cyclical upgrading of the labor force (Devereux 2004; Okun 1973) also suggest that less-skilled workers tend to lose their jobs in recessions, while more-skilled workers tend to move upward to higher-paying jobs in booms.
