Mutual gaze and visual co-orientation between mothers and infants :
(1980)
Tapes were coded as to the occurrence of mutual gaze and visual co-orientation, as well as any gestures and/or vocalizations which occurred during these visual interactions. Various visual and vocal measures derived from ...
Verbal interaction patterns in classes with teachers who had preservice training in the use of interaction process analysis compared to those without such training.
(1980)
Results indicated significant differences between the verbal interaction patterns of classes where the teacher had training in interaction process analysis, and the classes where the teacher had no such training. The trained ...

An investigation is made into the hail production characteristics of a supercell-type storm that occurred in Central Oklahoma on 29 May 1976. The main research tool employed is a three dimensional numerical hail growth ...
Development and properties of a self-bursting pellet as agglomerated from coal fines by use of an organic binder.
(1980)
In all aspects of the mining, processing, and handling of coal, fine particles are generated that are in many cases wasted. These fines can be agglomerated into strong and durable pellets by use of an organic binder which ...
