The popularity of gravity-return skyline logging systems is now increasing in the Western United States. Simplicity seems to be the basis for their success. While two drum yarders are most commonly used, ·some systems, such as the Wyssen, use only a single drum for yarding. Carriages commonly used with these...
Gradeability of log trucks is limited by either
vehicle rimpull or ground-tire adhesion. The analysis presented shows that log trucks in current use in the Pacific Northwest are limited by tire-slip gradeability rather than by rimpull. Analytic techniques were used to determine that gradeability is greatest for piggyback and least...
The comercial thinning of second-growth stands in the Pacific Northwest is becoming increasingly important for satisfying the demand for timber. Cable logging will require the rigging of smaller intermediate support trees rather than those utilized on old-growth timber sales. This paper reports on the results of a study designed to...

A two year experiment demonstrated electrical energy savings
through evaporator fan cycling in part of a full-sized refrigerated
controlled atmosphere apple storage facility in Yakima, Washington.
Room cooling demand and evaporator fan operation was controlled by
the bulk fruit temperature. Refrigerant temperature was regulated
by a computer controlled ramping sequence...
This study explored factors that lead to adaptation among married women in the military during the stressor of deployment. The Double ABCX Model of Family Stress and Adaptation (McCubbin & Patterson, 1 983a, 1 983b, 1 983c) provided a strong theoretical model for this study, on which the empirical model...
