A correlative attitude study of community education and municipal recreation professionals
(1976)
The purpose of this study was to determine the attitudes of municipal recreators toward community education and the attitudes of community educators toward public recreation. The sample populations consisted of a random ...
Preparation and evaluation of food grade copra
(1976)
Copra (dried coconut meat) meal after oil extraction is not used for human food because of microbial contamination during drying and storage. The objective of this research is to investigate the possibility of producing ...
Estimation of population abundances using auditory information
(1976)
Estimators of the mean individual calling rate and density of a wildlife population in a fixed area are derived on the basis of auditory information obtained by one or more listeners within the fixed area. An estimator of ...
Differential response of half-sib families of American sycamore (Platanus occidentalis L.) to contrasting moisture, pH, and fertilizer conditions
(1976)
This study was initiated to determine if differential response in growth and uptake of nutrients occurred among open-pollinated families of American sycamore when they were subjected to all combinations of three moisture ...
Peripheral plasma levels of l7-hydroxyprogesterone and progesterone in cyclic pluriparous cows during the preovulatory, estrous and ovulatory periods
(1976)
Peripheral plasma levels of 17-hydroxyprogesterone (17-OHP), progesterone (P) and luteinizing hormone (LH) were determined by radioimmunoassay procedures in cyclic pluriparous cows from 36 hr before estrus until time of ...
An investigation on spatial price discrimination in three countries
(1976)
The economics of space, particularly the theory of spatial pricing, has remained largely outside the basic structure of traditional (nonspatial) economic theory. This isolation stems from the fact that most of the literature ...
On-line suboptimal feedback control of a trickle-bed absorption column
(1976)
Suboptimal feedback controllers often yield a substantial improvement in control loop performance compared to that achieved with conventional feedback controllers. In this study, the design scheme proposed by Crosby [1] ...
Evaluating methods to predict potassium levels for optimum greenhouse tomato production (Lycopersicum escolentum Mill. var. Tropic)
(1976)
Two techniques were evaluated to predict the potassium (K) status of greenhouse tomatoes produced on a Lakeland loamy sand, "with a deficiency in K", "with an adequate K" and "with K accumulating in the soil". The three ...
Nitrification and heavy metal removal in the activated sludge treatment process
(1976)
A bench-scale, continuous flow, completely mixed activated sludge system was used to investigate the relationship of nitrification and other system parameters to heavy metal removal in the activated sludge waste treatment ...
Discriminant analysis with missing data
(1976)
A procedure is proposed as a solution to the problem of constructing a classification rule based on samples which contain incomplete vectors. Simulation studies are made comparing this procedure to the standard procedure ...
