By establishing rapport and confidentiality with one respondent, using established principles of qualitative interviewing [ 14], information is gained on four other households (an average of 20 females in the current study), achieving the statistical power usually limited to quantitative surveys.
The provision of biological samples or performing analysis using established techniques cannot by itself be considered an inventive step, and therefore does not in principle justify claims for intellectual property by the Expert Centres or a biobank.
In 1979 the Belmont Report established principles for the use of human subjects in scientific research.
A robust NN structure is established by using principle design data from the Matlab diagrams of system functions.
Sufficient conditions for the global stability of the endemic equilibrium are established by using the comparison principle.
In the present paper, we are concerned with a class of nonlinear Sturm-Liouville problems and we establish some qualitative properties of the eigenvalues by using variational principles.
Furthermore, by using homogenization principle, we give their error estimates by establishing the integral equation which reflects the relation between exact and approximate solutions.
By using the maximum principle and Ekeland's variational principle, we first establish a necessary condition for near-optimality, which reveals the 'minimum' qualification for an admissible control to be ε-optimal.
Here we aim to establish the potential of PtG as a new adsorbent for HF and SO3 molecules by using first-principles simulation.
The uniqueness of solutions of the fractional differential system is established by using the Banach contraction principle.
