These attributes are usually neglected because of the longstanding difficulty in treating "mixed-level" data, that is, combining both qualitative observations and quantitative information in a single powerful s
2. Example of a qualitative and a quantitative research questions: Research question Qualitative: ¬ In the topic of substance abuse cases in the emergency department, how does nursing substance abuse intervention compared to no intervention improve the outcomes of the patients in relationship to the...
The paper eventually gives the results of the work in the form of quantitative and qualitative reliability analysis of the observed process, which served to obtain complete information on the probability of top event in the process, as well as objective decision making and alternative solutions....
What is an example of a qualitative variable? What is the difference between physical and chemical properties in science? Explain how a chemical reaction can either release energy or store energy. What are the input and output reactions in photosynthesis? What are some tips on how to do stoichi...
The so called “failure mode and effects analysis” (FMEA) can give additional information which is useful during process characterization. The qualitative FMEA shown in Fig. 6 is based on the Ishikawa-diagram for extraction, similar to the one shown in Fig. 5. The ranking of parameters ...
Spectroscopy has the advantages of being non-destructive, rapid and efficient, and has gradually become an important research method for quality control and qualitative analysis of traditional Chinese medicine in recent years [10]. Fourier Transform Infrared Spectrometer (FTIR) has been reported to be...
It is interesting to note from a comparison between Fig.2and Fig.5that for a given set of impurities, the observed transition levels might occur at different absolute positions but follow the same qualitative trend. For instance, going from Pb\({}_{{\rm{Cd}}}\)to Cu\({}_{{\rm{Cd}...
Methods of model preselection used so far are based on qualitative criteria such as the identification of physical and chemical mechanisms of sorption for the investigated deposit and the migrating substances (an adequacy criterion) and on the basis of the simplicity criterion (Limousin et al. 2007...
Recent work on the solid-phase extraction of225Ac from urine showed one of the first examples for a qualitative and quantitative radiochemical analysis of low225Ac activities (Cusnir et al.2022). However, these authors used a self-made Y-imprinted resin for solid-phase extraction chromatography...
Location of detailed analysis are linked to corresponding figures. 1.4. Methods Twenty-three cores were logged in this study. Of these, 17 cores penetrate “A” Valley strata and are used to describe qualitative changes in the sedimentological and ichnological character of the IHS in individual ...
