OBJECTIVES Our first objective was to make an inventory of available instruments for the assessment of disabilities in gait and related activities in patients with rheumatic disorders. Our second aim was to investigate which of these instruments have acceptable methodological quality with regard to reliability and validity. Our third aim was to investigate the assumption that the evaluation of ...

the quantitative structure–property relationship (qspr) method is used to develop the correlation between structures of crude oil hydrocarbons (80 compounds) and their boiling point and water solubility. sub-structural molecular fragments (smf) calculated from structure alone were used to represent molecular structures. a subset of the calculated fragments selected using stepwise regression (fo...

the quantitative structure-property relationship (qspr) method is used to develop the correlation between structures of refrigerants (198 compounds) and their critical temperature. molecular descriptors calculated from structure alone were used to represent molecular structures. a subset of the calculated descriptors selected using a genetic algorithm (ga) was used in the qspr model development...

OBJECTIVES To develop and conduct a preliminary validation of selected subscales of an elder-friendly emergency department (ED) assessment tool. DESIGN Content validation of tool by an international panel. Construct validation using care ratings of ED lead physicians and nurses. SETTING Quebec, Canada. PARTICIPANTS The international panel comprised 34 clinicians, administrators, and resea...

the quantitative structure-retention relationship (qsrr) of nanoparticles in roadside atmosphere against the comprehensive two-dimensional gas chromatography which was coupled to high-resolution time-of-flight mass spectrometry was studied. the genetic algorithm (ga) was employed to select the variables that resulted in the best-fitted models. after the variables were selected, the linear multi...
