This study traces the evolution of federal legislation to control water pollution in the period between 1935 and 1965. In this legislative history, the function of interest groups, the actions of congressmen and congressional committees, and the role of the President and the Executive Branch are reviewed. The water pollution...
A complex and sometimes serious problem facing modern day forest
managers is that of estimating and analyzing potential on-site impacts
which result from forest activities. A major type of adverse impact
is man-Initiated forest erosion. This consequence can be substantially
magnified when forest harvest and road activities are implemented in...
Although some of the most difficult problems in forest management occur as a result of timber harvest operations, present methodology in harvest planning emphasizes guidelines which rely heavily upon the experience of the individual forest manager for their correct application. This study was undertaken in an effort to develop a...
Herbicides are being used as a tool by forest managers to speed
the restocking of sites where tree seedlings face competition from
grasses for limited moisture, light and nutrients. Retarded growth
or, more commonly, death of the seedlings would occur if a selective
herbicide was not used to control competing...
This thesis consists of two parts. Part I (Chapters 1,
2, 3) of this thesis concerns finding the best way of
running a reactor whose catalyst decays with use, and must
consequently be replaced or regenerated at regular
intervals. Chapter 1 introduces the problem, and Chapter 2
develops a one...
During the First World War, the need to secure a domestic supply
of nitrate compounds necessary to the manufacture of explosives caused
the federal government to undertake an extensive program of research
and development of industrial nitrogen fixation processes. These
government activities were to have far-reaching consequences for the
development...
Let K be a field, and G a finite group. G is said to be
K-adequate if there exists a division ring D, finite dimensional
over K, and with center K, such that G is contained in the
multiplicative group of nonzero elements of D.
In this dissertation we investigate...
A theory of higher order connections is developed as
a reduction of the structure group of the jet bundle of
sections of a smooth vector bundle. This definition leads
naturally to higher order curvatures and covariant derivatives.
Curvature Conditions for a second order partial differential
operator to have constant coefficients...
The topic of summability methods has been studied by many
although the name of G. H. Hardy and his classical work "Divergent
Series" is best known. Almost all of the early work was done using
single sequences or series. In the past 30 years research has been
done extending some...
