We assessed each independent variable in our model to ensure that the proportional hazards assumption was met by entering each variable in the model separately and calculating its interaction with time.
Ultra-Orthodox boys and girls are educated separately, and have little interaction with the opposite sex until their marriage night, when they are expected to consummate their union.
The aim was to study the leukemic cell viability under the action of HL1 and HL2 separately and in combination with C60 fullerene and to estimate their interaction with DNA in silico.
The interaction of DNA molecule with HL separately and in combination with C60 fullerene has been studied.
The interactions of DNA molecule with HL1 or HL2 separately and in combination with C60 fullerene have been studied.
By use of computer simulation, the interactions of DNA molecule with HL1 or HL2 separately and in combination with C60 fullerene were studied.
HV and PY performed the computer modeling of interaction of DNA molecule with dimorfolido-N-trichloroacetylphosphorylamide or dimorfolido-N-benzoylphosphorylamide separately and in combination with C60 fullerene.
To evaluate the interaction between the major constituents of the essential oil, some constituents were tested separately and in mixtures with concentrations equal to those in the essential oil.
However, all these areas tend to be investigated separately and in parallel with human factors studies.
Explanatory variables with P ≤ 0.20 when assessed separately and the interaction terms; parity by WIM, parity by milk yield, and WIM by milk yield were included in an extended model.
