Relationships between planktonic, epiphytic, and epipelic diatom populations in selected ponds of Brazos County, Texas
(1969)
Three ponds located in Brazos County, Texas, were sampled regularly for a period of one year, from August 1964 through August 1965, in order to study diatom populations on a seasonal basis. Samples were collected from each ...
An economic model for evaluating alternative government programs in rice
(1969)
An economic model of the rice demand and supply relationships was developed that permits the estimation of domestic and export quantity-price relationships for rice and the determination of the effects of selected changes ...
Adsorption equilibria of multicomponent mixtures
(1969)
A model based on kinetic principles is developed for the adsorption of mixtures of gases in any number of layers by solid adsorbents. These models are hereafter referred to as the kinetic models. Equation of state which ...
Development of a model program in engineering graphics based upon behavioral objectives evaluated by authorities in the field
(1969)
The purpose of this study is to develop a model program in engineering graphics based upon behavioral objectives evaluated by a panel of experts in educational technology and in engineering graphics. Behavioral objectives ...
A genetic and biochemical analysis of [alpha][subscript s1]-casein and [beta]-casein in bovine species
(1969)
Data for this study were obtained from milk collected from samples of five beef breeds and one dairy breed of cattle located at Livestock and Forage Research Center, McGregor, Texas; Beef Cattle Center and Dairy Cattle ...
Nuclear structure studies in the mass-90 region with the (³He, d) reaction
(1969)
The (³He,d) reaction on target nuclei of ⁹⁰Zr, ⁹¹Zr, ⁹²Zr and ⁹³Nb was studied using 31-MeV ³He ions from the Oak Ridge Isochronous Cyclotron. The deuteron groups corresponding to low-lying excited states in the residual ...
Chromosome patterns of Boophilus annulatus, Boophilus microplus and their F₁ hybrids
(1969)
Chromosome patterns in excised gonads from laboratory-reared Mexican Boophilus annulatus (Say), B. microplus (Canestrini) and their reciprocal F₁ hybrids were studied. Mitotic and meiotic divisions were observed in males ...
Direct numerical solution of the Schrödinger equation for H³
(1969)
The importance of the three-nucleon problem to understanding the nucleon-nucleon interaction is discussed. The general formulation of the three-nucleon problem is discussed. A reduction of the problem to a coupled set of ...
Relationship between primary productivity (C¹⁴ method) and phytoplankton in a mesotrophic lake
(1969)
The relationships between primary productivity and phytoplankton numbers and volume were studied in a small mesotrophic lake near College Station, Texas, between April 1966 to February 1967. Each of four seasonal experiments ...
Movement and distribution of ⁴²K and ¹³⁴CS in Schizachyrium scoparium (Michx.) Nash tillers, clones, and associated habitat
(1969)
Movement and distribution of ⁴²K and ¹³⁴Cs were investigated within individual Schizachyrium scoparium (Michx.) nash (little bluestem) tillers grown in a greenhouse and under natural conditions. The field studies were ...
