Carefully designed experiments of a single evaporating droplet subject to gas flow have also been conducted to provide the first hand data for model comparison.
The present study was conducted to assess and compare the environmental consequences of recycled aggregates production from C&D waste and waste glass, and natural aggregate production from virgin materials by LCA by using case specific and first hand data.
Herein we report our first hand data statistics regarding China mainland.
Direct observation is most preferred because it allows first hand data collection in a natural setting as used in prospective cohort studies in Nigeria and Brazil [ 40, 41].
Yet often, those agencies haven't done the research either, since they also rely on second-hand data.
They did so by gathering first-hand data and inserting it into public media like newspapers, billboards, even television.
The development of the telescope will allow Chinese scientists to have their own first-hand data and equipment, rather than having to rely on information supplied by foreign space telescopes.
As there are overlapping languages between the first-hand data and the second-hand data, the total data sources are from 69 languages.
The geometrical configuration repeated below has been verified by all the first-hand and second-hand data with no exception, thus enjoying universal validity (Fig. 24).
Among all the first-hand data and the second-hand data that we collected in this research, no such data is found to express only Repetition and Greater Degree.
Based on first-hand data collected from 40 languages and second-hand data from reference grammar of 38 languages, a conceptual space centering on the concept of Repetition is established in this research.
