Ambient groundwater quality of the Aravaipa Canyon Basin : a 2003 baseline study
No full textabstract: The Aravaipa Canyon groundwater basin covers approximately 517 square miles in southeastern Arizona within Graham and Pinal counties. Largely undeveloped, the remote basin has an estimated 135 residents and includes the community of Klondyke. Low-intensity livestock grazing is the predominant land use although there are some irrigated fields and orchards along Aravaipa Creek. Historic mining activity resulted in the creation of the Klondyke Tailings Water Quality Assurance
Revolving Fund site in 1998. Groundwater is used for all domestic purposes within the basin as well as most irrigation and stock water supplies. Irrigation uses the most groundwater in the basin.Open-file report (Arizona. Department of Environmental Quality) ; 13-01Fact sheet (Arizona. Department of Environmental Quality) ; FS 13-0
Ambient groundwater quality of the Lower San Pedro Basin : a 1999-2000 baseline study
No full textabstract: The Lower San Pedro Groundwater Basin (LSP) baseline groundwater quality study was conducted by the Arizona Department of Environmental Quality in 2000. Located in southeastern Arizona, this semiarid basin is drained by the San Pedro and Gila Rivers. The LSP is a rural landscape with scattered towns and two
extensive copper mining and processing operations. Groundwater from three aquifers (floodplain, unconfined basin-fill, and confined basin-fill or artesian) and fractured mountain hardrock is the principle source of water supply. For this study, 63 groundwater sites were sampled for inorganic constituents. In addition, fewer sites were also sampled for Volatile Organic Compounds (25), radiochemistry (19), radon (19), and pesticide (2) analyses. Eighteen (18) percent of sample sites had concentrations of at least one constituent that exceeded a health-based, Federal or State water-quality standard.Open-file report (Arizona.

Ambient groundwater quality of the Upper Hassayampa Basin : a 2003-2009 baseline study
No full textabstract: The Upper Hassayampa groundwater basin covers approximately 787 square miles within Maricopa and Yavapai counties and is located about 60 miles northwest of Phoenix. The basin is characterized by mid-elevation mountains and had an estimated population of 10,479 in 2000. The largest population center is the Town of Wickenburg. Other communities include Congress and Groom Creek. Low-intensity livestock grazing is the predominant land use and most ranches have limited acreages of irrigated pasture to raise additional animal feed. There are no surface water diversions or impoundments besides small stock ponds within the basin. Groundwater is the only source for public water supply, domestic, irrigation and industrial purposes. Public water supply uses the most groundwater in the basin.Open-file report (Arizona. Department of Environmental Quality) ; 13-03Fact sheet (Arizona. Department of Environmental Quality) ; FS 13-1
Groundwater quality in Arizona : a 15-year overview of the ADEQ ambient monitoring program (1995-2009)
No full textabstract: In pursuing its mandated mission to characterize groundwater quality in the state, the Arizona Department of Environmental Quality has collected samples from 1,477 sites over a 15-year period between 1995 and 2009. The sample sites consisted mainly of domestic, stock, irrigation and municipal wells and, to a lesser extent, springs used predominantly for watering stock and wildlife. Sampling activity was conducted within 35 of the state’s 51 officially designated groundwater basins and covered much of Arizona with the exception of Native American tribal lands. The data provide comprehensive and reliable information on the occurrence and concentrations of groundwater contaminants. This is critical knowledge for the estimated 100,000 private domestic wells in the state whose owners represent about 5 percent of Arizona’s population.Open-file report (Arizona.

Social software product lines
No full textSoftware product lines are an engineering paradigm meant to systematically configure software products of reusable assets so that development effort and time are minimized. Config-uring a high-quality product is a challenging design activity, main-ly because quality is a dynamic property and hardly predictable by designers at design time. In this position paper, we propose Social Software Product Lines (SSPL) as a new development paradigm which involves users as collaborators in judging software products quality and guiding configuration in a lifelong style. SSPL para-digm advocates two principles. The first is that quality has to be evaluated iteratively during the product operation so that quality evaluation is maintained up-to-date. The second is that users are the main evaluator of quality and their feedback is a primitive driver of reconfiguration. At runtime, SSPL keeps obtaining users’ quality feedback and planning upon reconfiguration to deliver the product shown most adequate by the users’ community. We discuss motivations and foundations of SSPL and outline a set of research directions
Prognosis in traumatic brain injury
No full textIntroduction:
The
general
purpose
of
this
thesis
was
to
study
prognosis
in
traumatic
brain
injury
(TBI)
patients,
with
the
aim
of
providing
useful
and
practical
information
in
clinical
practice
and
clinical
research.
The
specific
objectives
were:
to
develop
and
validate
practical
prognostic
models
for
TBI
patients
and
to
assess
the
validity
of
the
Modified
Oxford
Handicap
Scale
(mOHS)
for
predicting
disability
at
six
months.
Methods:
A
survey
was
first
conducted
to
understand
the
importance
of
prognostic
information
among
physicians.
A
systematic
review
of
prognostic
models
for
TBI
patients
was
then
carried
out.
Prognostic
models
were
developed
using
data
from
a
cohort
of
10,008
TBI
patients
(CRASH
trial)
and
validated
in
a
cohort
of
8,509
TBI
patients
(IMPACT
study).
Two
focus
groups
and
a
survey
were
conducted
to
develop
a
paper-based
prognostic
score
card.
The
correlation
between
the
mOHS
and
the
Glasgow
Outcome
Scale
(GOS)
was
assessed,
the
validity
of
different
mOHS
dichotomies
was
assessed,
and
the
discriminative
ability
of
the
mOHS
to
predict
GOS
was
evaluated.
Results:
Doctors
considered
prognostic
information
to
be
very important
in
the
clinical
management
of
TBI
patients,
and
believed
that
an
accurate
prognostic
model
would
change
their
current
clinical
practice.
Many
prognostic
models
for
TBI
have
been
published,
but
they
have
many
methodological
flaws
which
limit
their
validity.
Valid
prognostic
models
for
patients
from
high
income
countries
and
low
&
middle
income
.countries
were
developed
and
made
available
as
a
web
calculator,
and
as
a
paper
based
score
card.
The
mOHS
was
strongly
correlated
with
and
was
predictive
of
GOS
at
six
months.
Conclusion:
The
prognostic
models
developed
are
valid
and
practical
to
use
in
the
clinical
setting.
The
association
between
mOHS
and
GOS
suggest
that
the
mOHS
could
be
used
for
interim
analysis
in
randomised
clinical
trials
in
TBI
patients,
for
dealing
with
loss
to
follow-up,
or
could
be
used
as
simple
tool
to
inform
patients
and
relatives
about
their
prognosis

Factors Associated to Purchase of Quality-Labelled Beef
No full textThe aim of the present study is to identify the factors associated to purchase of quality-labelled beef. For this purpose a total of 364 surveys were carried out on buyers of beef in three Spanish cities. The sample was divided into three groups of buyers according to the beef purchasing habits with a quality label. A logistic regression analysis was used to estimate the differences between groups. The results show the importance of the production region as a quality aspect. Income level, association of quality-labelled beef with “guarantee and tradition” aspects, purchasing frequency, place of purchase, production systems and lifestyles are all variables that enabled us to establish differences between groups.beef quality, quality label, consumer perception, Demand and Price Analysis,
