To assist in the design of enhanced reductive dechlorination systems for in situ remediation of chlorinated solvent source zones, the software BUCHLORAC (BUffering of deCHLORination ACidity) was developed to predict the amount of buffer required to maintain the groundwater pH in a DNAPL treatment zone within the optimal range for dechlorinating bacteria. Reductive dechlorination is an acidformi...

In the cultural heritage area, it is of fundamental importance to characterize and classify the conservation state of the materials constituting ancient monuments, in order to study and monitor their decay. Generally, the decay diagnosis is provided by “naked eye” analysis done by expert scientists “walking around” the artifact and recording the conservation state of each individual element the...

During 2001, we used active acoustical sampling (Anabat I/) to survey foraging habitat relationships of bats on the Savannah River Site (SRS) in the upper Coastal Plain of South Carolina. Using an a priori information-theoretic approach, we conducted logistic regression analysis to examine presence of individual bat species relative to a suite of microhabitat, stand, and landscape-level feature...

Riparian vegetation is vulnerable to human impact worldwide, and this is especially so in arid areas, yet there have been few quantitative studies and this is especially so in Spain. The state of the riparian vegetation along three major rivers and seasonal watercourses of southeastern Spain was evaluated during 1992–93, using the species composition and community structure in watercourses of d...

The Anthropocene is an uneven phenomenon. Accelerated shifts in the functioning of Earth System are mainly driven by production and consumption wealthy economies. Social, environmental health costs such industrialization, however, bear on low-income communities inhabiting severely degraded territories polluting activities (i.e., sacrifice zones). How global, national local socio-economic govern...

This paper describes the scale and nature of agricultural production in urban, suburban and peri-urban zones of Mexico City and how these have adapted to the changing demands from urban populations for food, wood and recreation. It also demonstrates how agricultural producers have successfully adapted their products and their production methods, including building on traditional production syst...

Paper-based microfluidic devices are emerging as a new technology for simple, low-cost, portable, and disposable diagnostic and monitoring platform. This article presents a novel method for fabricating microfluidic devices on paper by means of octadecyltrichlorosilane self-assembling and UV/O3-patterning. The hydrophilic filter paper was uniformly coated with a hydrophobic layer of octadecyltri...

Throughout the boreal and temperate zones, forest restoration efforts attempt to counteract negative effects of conversion to other land use (afforestation and remediation) and disturbance and stress on existing forests (rehabilitation). A p forest restoration o ropriate silvicultural practices can be designed for any %.jective. Most common objectives include timber, wildlife habitat for game s...

A bacterium that was capable of metabolizing atrazine at very high concentrations (>1,000 ppm) was isolated from a herbicide spill site. The organism was differentiated by observing clearing zones on indicator agar plates containing 1,000 ppm atrazine. Detailed taxonomic studies identified the organism as a Pseudomonas sp., designated ADP, that was dissimilar to currently known species. Pseudom...
