In this research a model is developed to predict population for relatively
rural areas experiencing rapid economic development. Of the many
ways to predict population size, in this research a "demographic-economic"
model is chosen for use. The economic variables which aid in projecting
population are total employment, and net changes...
A comparison was made of the d.c. conductivity of KCI:Pb²⁺
and KCl:PbO single crystals at temperatures greater than 325°C.
The energy of activation was 0.72 ev for all crystals. Lead concentration
was determined by chemical, optical and electrical methods. The
half band width of the UV absorption band at 273...
The simultaneous diffusion of Ca 2+ and Sr 2+ ions in purified
single crystals of KC1 and NaC1 was studied over the temperature
ranges from 451°C to 669°C in KC1 and from 448°C to 683°C in NaCl.
A radioactive tracer technique was used in two types of measurements:
diffusion from...
Linear programming is now widely accepted and used by researchers and industrial management people, but its adoption by farm managers has been slow. This study concentrates on the development of improved data transmittal techniques for farm organization linear programming. The program model is designed to analyze crop production alternatives. Models...
The investigation
of impurity effects on the properties of alkali
halide crystals has often been difficult because of the variation of procedures used in various experiments.
The purpose of this work is to
develop a self consistent method of measuring the IV dipole polarization properties of single crystals while eliminating...
