Transplantation and preliminary vegetative propagation studies of selected Chihuahuan Desert shrubs
(1977)
A survey of the literature indicated an increased interest in native arid-land shrubs as potential ornamentals and for other uses. Five Chihuahuan Desert shrubs were selected for study: Artemisia filifolia Torr. (Compositae), ...
Ecology and herbicidal control of selected perennial range weeds of South Texas
(1977)
Three species of perennial range weeds, common goldenweed (Isocoma coronopifolia (Gray) Greene), Drummond's goldenweed (Isocoma Drummondii (T.&G.) Greene), and spiny aster (Aster spinosus Benth.) were studied relative to ...
Effectiveness of teacher identification of gifted students as a function of training
(1977)
The purpose of this study was to (a) train teachers in the identification of gifted and talented students, (b) determine whether such training significantly improves teachers' ability to identify gifted and talented students, ...
The effect of growth hormones, container design, and grafting techniques on more rapid propagation of pecan cultivars on seedling rootstocks
(1977)
The influence of growth hormones, container design, and grafting techniques on more rapid propagation of pecan cultivars on seedling rootstocks was studied. GA₃ at 5000 ppm significantly promoted stem enlargement of seedlings ...
The nature of acidity in selected acid soils
(1977)
Most of the soils in the eastern one-third of Texas are acid. To this date little work has been done to evaluate the acid status of these soils. The present effort was initiated to study total acidity and the contribution ...
Standing crop, diets, travel and weight changes under short-duration and continuous grazing
(1977)
The influence of stocking pressure at a fixed stocking rate (5.6 ha/A.U.) was investigated by comparing continuous grazing with a short-duration grazing (SDG) system from March through December 1975. The SDG system consisted ...
Selection of the working set window size
(1977)
A function is developed which describes the cost of executing a program when using demand paging. The function includes the cost of paging operations and memory usage. Several theorems are proven which determine, in a ...
Constrained nonlinear estimation applied to earth resources satellite data
(1977)
A variate transformation model is employed to estimate the percentage of a large land segment covered by a particular crop based on spectral intensity data from National Aeronautical Space Administration's Earth Resources ...
Herbage dynamics and nitrogen cycling in two rangeland ecosystems on the Edwards Plateau, Texas
(1977)
This study was conducted on the Sonora Research Station near Sonora, Texas, in the southwestern portion of the Edwards Plateau. The objective of the study was to determine the effects of two long-term grazing systems on ...
Effects of selected processing parameters on rehydration and texture of freeze-dried compressed carrot bars
(1977)
The effect of moisture content, microwave plasticization time, compression force and dwell time on texture of freeze-dried compressed carrots was determined. Response Surface Methodology demonstrated that moisture was the ...
