Ecological validity of laboratory assessments of child temperament: evidence from parent perspectives.

The structure, stability, and validity of child temperament traits have primarily been examined with parent questionnaire methods, but laboratory methods represent an important complement. However, the novel setting and contrived scenarios of laboratory methods and their low convergence with parent questionnaire methods have led some to question their ecological validity. We tested this assumption by employing parents as sources of information regarding the ecological validity of laboratory assessments of child temperament.

Finding seconds count after contact with blood (and that is all I did).

On a surface, upon its contact with plasma at least five proteins in succession displace each other within 1 min. It took me about 30 years to discover that.

Effects of secondary flow caused by a curved channel on plasma protein adsorption to artificial surfaces.

The effects of secondary flow induced by a curved channel on fibrinogen deposition and replacement on a glass surface were studied. Platelet adhesion to surface-bound fibrinogen was also studied to indicate how secondary flow may affect thrombogenesis on artificial surfaces. A saline pre-wetted channel with straight and curved sections was exposed to flowing plasma at a Reynolds number of 28.
