Low streamflow in the Myakka River Basin Area in Florida
The Sarasota-Manatee area is a water-short area and the study
was undertaken in 1963 in order to determine the storage capability
and discharge rates of the Myakka water shed. It was found
that many of the streams of the water shed were virtually dry
during part of every year. However, the basins of the Myakka
lakes, through which the river flows offer some storage potential,
that if properly developed would provide a continuance drift of
about seven million gallons of water per day of good quality water
that would be high in color and temperature upon occasion. With
reasonable treatment some of this water could be used to meet
the present needs of the rapidly expanding coastal areas. (PDF contains 40 pages.
Test well exploration in the Myakka River Basin area, Florida
In recent years, difficulties encountered in obtaining ground-water supplies
with acceptable chemical characteristics in the Myakka River basin area led to
the implementation of a test drilling program. Under this program, well drilling
and data collection were executed in such a manner that all water-producing
zones of the local aquifers, together with the quality and quantity of the water
available, were effectively identified.
A step-drilling method was utilized which allowed the collection of
formation cuttings, water samples, and water-level data, from isolated zones in
the well as drilling proceeded. The step drilling procedure is described. The
driller's logs, geophysical logs, and chemical quality of water tables are
presented.(Document has 66 pages.
Quotients of finite-dimensional operators by symmetry representations
A finite dimensional operator that commutes with some symmetry group admits
quotient operators, which are determined by the choice of associated
representation. Taking the quotient isolates the part of the spectrum
supporting the chosen representation and reduces the complexity of the problem,
however it is not uniquely defined. Here we present a computationally simple
way of choosing a special basis for the space of intertwiners, allowing us to
construct a quotient that reflects the structure of the original operator. This
quotient construction generalizes previous definitions for discrete graphs,
which either dealt with restricted group actions or only with the trivial
representation.
We also extend the method to quantum graphs, which simplifies previous
constructions within this context, answers an open question regarding
self-adjointness and offers alternative viewpoints in terms of a scattering
approach. Applications to isospectrality are discussed, together with numerous
examples and comparisons with previous results.Comment: 43 pages, 8 figure
Is there any room for the doctrine of fundamental rights of states in today's international law?
This article serves as a general substantive introduction to the special issue on the fundamental
rights of states in international law. It introduces the concept in theoretical and doctrinal terms, and
lays out the questions that will be addressed by the contributions to the special issue. These questions
include: 1) What do attributes like ‘inherent’, ‘inalienable’ and ‘permanent’ mean with regard to
state rights?; 2) Do they lead to identifying a unitary distinct category of fundamental rights of
states?; 3) If so, what is their source and legal character?; 4) What are their legal implications, eg,
when they come into conflict with other obligations of the right holder or with the actions of other
states and international organisations?; and ultimately, 5) Is there still room in today’s international
law for a doctrine of ‘fundamental’ rights of states? The article reviews the fundamental rights of
states in positive law sources and in international legal scholarship, and identifies the reasons for
a renaissance of attention for this doctrine
