This study expresses the hypothesis that historical patterns of national beef cow herd accumulation and liquidations (the cattle cycle) have been related to investment incentive differences across cow ages through time, resulting each year in changes in herd age structure,
performance and potentials for adjustment in subsequent years. A review...
An integrated sampling and gamma ray spectrometry system has
been developed for analysis of TRIGA reactor primary cooling water.
A microcomputer controls pumps and valves using BASIC and assembly
language programs to pump 300 ml liquid samples into a reference
geometry surrounding a Ge(Li) detector. Gamma ray spectra are
acquired...
Problems with aluminosilicate scales in pulp and paper recycle streams create an
interest in the formation mechanism and the chemical equilibrium of aluminosilicates.
Evaluating solubility data from a system containing Na⁺ CI⁻, and OH⁻ ions as well
as aluminium and silicon compounds, allowed to elucidate the characteristics of the
aluminosilicate...
This study develops an improved method for understanding
economic production relationships in small scale
fisheries. This method postulates that gross revenue is a
function of physical input quantities, and is based upon
the transcendental logarithmic function to derive factor
share equations for each of the five inputs in the model....
Fishing firms in Oregon operate in a complex and dynamic physical, biological and institutional environment. Within this environment, managers of these firms will attempt to maximize some objective function which may include profit. This maximization is dependent upon the level of output, or the levels of inputs. Given a relationship...
The research undertaken in this study deals with three topics related to the prediction of thermodynamic properties of electrolytes in aqueous solutions. In the first, Pitzer ion interaction parameters for 304 single electrolytes were evaluated from recently published osmotic coefficient data at 25°C by using multiple regression analysis to fit...
Rotary dryers are the most commonly used wood drying system in the particleboard industry. These dryers also play an increasingly important role in drying wood residues for fuel. Many potential benefits may be realized through an improved understanding of the rotary drying process. A rotary dryer simulation model was developed,...
