Under the National Pollution Discharge Elimination System (NPDES),
many municipal and industrial wastewater treatment facilities must
perform Whole Effluent Toxicity (WET) Testing. Regulatory agencies
determine the level of compliance of each facility by making
inferences about the results of these tests. There has been some
concern regarding appropriate ways to integrate WET tests into
NPDES permits. The central issue of this concern involves
determining the relationship between WET tests and instream
biological conditions. Previous research (WERF project 95-HHE-1)
has examined this issue using historical data. Because of issues
with data comparability, i.e. questionable data quality, and
project design, results were inconclusive. This study plan was
designed to collect new data on method performance for both WET and
bioassessment that would help answer the outstanding question. The
study plan was designed using a Data Quality Objective (DQO)
approach in which DQOs and MQOs were defined. These DQOs and MQOs
were characterized using technical input from many scientists from
federal, state, and private organizations. It was through this
effort that certain technical design issues arose that needed
further investigation before implementing the definitive study.
Among these issues were determining if DQOs and MQOs were
achievable, and determining appropriate biological assessment
methods for various ecoregions (e.g. effluent dependent streams in
the arid west). In order to appropriately address these issues, it
was determined that a pilot study would be implemented before the
definitive study. The pilot study is designed as a one-year study
in which participating facilities will perform quarterly WET tests
(Ceriodaphnia, P. promelas, Selenastrum) and at least one
bioassessment (macroinvertebrate, fish, algae) as well as providing
other prescribed data requirements. Results of the pilot will
provide answers to technique design issues and will ultimately
determine the most appropriate study design for the definitive
study.
A balanced combination of introductory and advanced topics provides
a new and unique perspective on the quantum field theory approach
to condensed matter physics. Beginning with the basics of these
subjects, such as static and vibrating lattices, independent and
interacting electrons, the functional formulation for fields and
different generating functionals and their roles, this book
presents a unified viewpoint illustrating the connections and
relationships among various physical concepts and mechanisms.
Advanced and newer topics bring the book up to date with current
developments and include sections on cuprate and pnictide
superconductors, graphene, Weyl semimetals, transition metal
dichalcogenides and topological insulators. Finally, well-known
subjects such as the quantum Hall effect, superconductivity, Mott
and Anderson insulators, and the Anderson-Higgs mechanism are
examined within a unifying QFT-CMP approach. Presenting new
insights on traditional topics, this text allows graduate students
and researchers to master the proper theoretical tools required in
a variety of condensed matter physics systems.
An argument that we must read code for more than what it does-we
must consider what it means. Computer source code has become part
of popular discourse. Code is read not only by programmers but by
lawyers, artists, pundits, reporters, political activists, and
literary scholars; it is used in political debate, works of art,
popular entertainment, and historical accounts. In this book, Mark
Marino argues that code means more than merely what it does; we
must also consider what it means. We need to learn to read code
critically. Marino presents a series of case studies-ranging from
the Climategate scandal to a hactivist art project on the US-Mexico
border-as lessons in critical code reading. Marino shows how, in
the process of its circulation, the meaning of code changes beyond
its functional role to include connotations and implications,
opening it up to interpretation and inference-and misinterpretation
and reappropriation. The Climategate controversy, for example,
stemmed from a misreading of a bit of placeholder code as a
"smoking gun" that supposedly proved fabrication of climate data. A
poetry generator created by Nick Montfort was remixed and
reimagined by other poets, and subject to literary interpretation.
Each case study begins by presenting a small and self-contained
passage of code-by coders as disparate as programming pioneer Grace
Hopper and philosopher Friedrich Kittler-and an accessible
explanation of its context and functioning. Marino then explores
its extra-functional significance, demonstrating a variety of
interpretive approaches.
