Biological activities of the harvester ant, Pogonomyrmex owyheei Cole, in central Oregon

Creator:: Willard, John Royal Alexander
Abstract:: The mound-building harvester ant, Pogonmyrmex owyheei Cole, (formerly included in the species occidentals) is widely distributed on the semi-arid rangeland east of the Cascade mountains in Oregon. Because of its seed foraging and vegetation clearing habits, this ant has been considered as a possible competitor with livestock and wildlife for...

The steady state flow of water through unsaturated soil in the low capillary potential region

Creator:: Stammers, William Norman
Abstract:: Several investigators have recently called attention to the fact that the flux equation for water movement in unsaturated soils may not be an appropriate mathematical model for the development of the theory of unsaturated flow phenomena. An analytical theory is developed for the purpose of testing the validity of the...

A study of relative speeds of medical x-ray film and intensifying screen combinations

Creator:: Gross, Richard Eugene
Abstract:: The objective of this study was to determine the relative speeds of available medical x-ray films exposed directly to x-rays and exposed in combination with various types of intensifying screens. The information obtained from this sensitometric data was used to obtain factors by which a radiographic exposure technique with one...

Dynamic simulation model of transpiration process with stomatal control mechanism

Creator:: Woo, Kwang Bang
Abstract:: Because the life processes of the plant are related in a complex way to the balance between the water demand of the atmosphere and the water availability to the plant root, an exploration of the dynamic status of water in the plant is very important. The stomata constitute the main...
