Background: Data analysis is a complex and contested part of the qualitative research process, which has received limited theoretical attention. Researchers are often in need of useful instructions or guidelines on how to analyze the mass of qualitative data, but face the lack of clear guidance for using particular analytic methods.
For qualitative analysis, time-varying capacitors are introduced and a lumped parameter model, considering nonlinear electrostatic force and midplane stretching of microbeam, is adopted to examine ...
For qualitative analysis, time-varying capacitors are introduced and a lumped parameter model, considering nonlinear electrostatic force and midplane stretching of microbeam, is adopted to examine the system statics and dynamics. The Method of Multiple Scales (MMS) is applied to determine the primary resonance solution under small vibration ...
A total of 132 components in RYP including flavonoids, triterpenoid saponins, phenylpropanoids, and monoterpenoid glycosides were identified or tentatively characterized by authentic compounds or accurate masses and fragmentation, in which 52 characteristic components were selected for further quantitation by UPLC-MS/MS.
The direct detection, without extensive sample preparation, is a clear advantage of DEMS/OEMS, enabling qualitative and quantitative analysis of volatile products and …

The results showed that the ultra-high-performance liquid chromatography coupled with linear ion trap quadrupole Orbitrap high resolution mass spectrometry (UHPLC-LTQ-Orbitrap) could comprehensively elucidate the chemical constituents of Fufang Gancao Tablets and their migrating components in rat plasma, providing scientific basis for further studying the …
Qualitative research is the opposite of quantitative research, which involves collecting and analyzing numerical data for statistical analysis. Qualitative research is commonly used in the humanities and social sciences, in subjects such as anthropology, sociology, education, health sciences, history, etc.
Most qualitative data analysis approaches begin with a coding process, in which significant parts of text are first identified and then coded.
Qualitative conventional content analysis guided the data analysis and consisted of 3 phases: preparation, organizing, and reporting. 6, 7 During the preparation phase, the team (all with previous qualitative research experience) immersed themselves in the data by independently and then jointly reviewing transcripts to get a sense of the whole. The team …
Analyzing the HPLC-collected components by IR or mass spectroscopy enables reliable qualitative analysis. Fig. 11 Identification by comparing retention times in a standard sample (upper) and an unknown …
Qianggan capsule (QGC) is a complex preparation composed of 16 traditional Chinese medicines (TCM) that can clear heat and dampness, fortify the spleen and blood, typify qi and relieve depression. However, the chemical composition of QGC remains incompletely understood, despite its clinical use in t …
The composition of relatively complex mixtures of metal ions can be determined using qualitative analysis, a procedure for discovering the identity of metal ions present in the mixture (rather than quantitative information about their …
With your data prepped and coded, it''s time to move on to the heart of the qualitative research process: analysis.This is where you uncover insights and make sense of the data through the lens of your research questions.. There are many different qualitative methods available, but the four most common ones are:. Thematic Analysis: Focuses on identifying, analysing, and …
Advances have been made in the electronic characterization and analysis of thin-film ferroelectric (FE) memory capacitors using capacitance vs. voltage (C-V) measurements.
