In this thesis we investigate the extension of certain theorems
of additive number theory to three algebraic systems. A generalization
of a theorem by Cauchy and Davenport on the cardinality of the
sum of two sets of residue classes is given. We obtain and compare
estimates for the order of...
Allen Freedman defined a density space to be the ordered pair
(S,𝓕) where S is a certain kind of semigroup called an s-set and 𝓕
is a special type of family of finite subsets of S called a fundamental
family on S. Several properties for density spaces are
obtained, and...
The fate of hexachlorophene, a widely used bactericide, was
investigated using both intact male rats and rabbits and liver microsomes
from male rats. Hexachlorophene administered intraperitoneally
was found to be rapidly absorbed and distributed to all the
tissues of the animals. Excretion of the chemical in both species
occurred slowly,...
The subcellular fractions of liver and kidney from three bearded
seals (Erignathus barbatus nauticus) and three walrus (Odobenus
rosmarus divergens) were analyzed for cadmium and mercury content,
and the results were compared with the results of subcellular
fractionation of the same organs from two sea lions (Zalophus callfornianus
californianus) obtained...
Geometric design standards have not been developed specifically for low volume roads. Design standards and criteria are extrapolated from higher standard roadways that are often not relevant to low volume roads. Safety is a primary criterion used for selection of design standards along with economic, financial, social and environment factors....
Evaluation of the safety hazards along a highway is usually
performed at specific locations and on known hazards. But, it is also
important to find any unrecognized hazards and their locations. Many
factors contribute to accident potential, and the combined effect of
several of them could produce a hazard that...
The development of a pavement management system for low-volume roads is a difficult task. There are many interrelated activities that must be considered, such as planning, design, construction, maintenance, and pavement evaluation. This paper addresses the evaluation and maintenance components of a pavement management system for low-volume roadways and provides...
Numerous analytical aids are available to apple producers to assist them in the decision problem of choosing among alternative apple harvesting systems. However, a majority of these techniques
fail to recognize the effect of apple orchard yield variability on system performance and economic efficiency. Furthermore, many of the suggested procedures...
