The vast occurrence of mine drainage worldwide, documented in descriptive studies, presents a staggering challenge for remediation. Any tool that can move beyond descriptive study and helps to evaluate options for remediation in a way that maximizes improvements to the water quality of streams and minimizes cost of remediation could save valuable resources and time. A reactive solute transport ...

Grasslands established on drained peat soils are regarded as negligible methane (CH4 ) sources; however, they can still exhibit considerable soil CH4 dynamics. We investigated archaeal community composition in two different fen peat soils and one bog peat soil under permanent grassland in Denmark. We used terminal restriction fragment length polymorphism (T-RFLP) fingerprinting and clone librar...

We carried out two studies to test the hypothesis that altered central serotonergic function, as assessed by lower prolactin (PRL) response to fenfluramine (D-FEN), is more closely associated with suicidal behavior than a particular psychiatric diagnosis. A D-FEN test was performed in 85 major depressed inpatients, 33 schizophrenic inpatients, and 18 healthy controls. We showed that PRL respons...

We describe five demonstration programs for displaying variants of effects reported in the vision literature. The demonstrations use a windowed workstation environment, the X Window System Version 11. The performance of the window system is analyzed in terms of our implementation experience and suggestions are made for future window system architectures based on that experience. The visual effe...

BACKGROUND Fenugreek (Trigonella foenum-graecum) is a leguminous, annual plant originating in India and North Africa. In recent years Fenugreek has been touted as an ergogenic aid. The purpose of this study was to evaluate the effects of Fenugreek supplementation on strength and body composition. METHODS 49 Resistance trained men were matched according to body weight and randomly assigned to ...

Removal of flap DNA intermediates in DNA replication and repair by flap endonuclease-1 (FEN-1) is essential for mammalian genome integrity. Divalent metal ions, Mg(2+) or Mn(2+), are required for the active center of FEN-1 nucleases. However, it remains unclear as to how Mg(2+) stimulates enzymatic activity. In the present study, we systemically characterize the interaction between Mg(2+) and m...

Zoltai, S.C. 1995. Regional variations in peatland ecosystems of west-central Canada through time. Gunneria 70: 35-42. Peatland ecosystems respond to major changes in their environment induced by prolonged changes in climate. In the western boreal region of Canada, permafrost occurs only in Sphagnum-dominated peatlands. In the north, the palsas and peat plateaus are associated with well-defined...
