First results on the water chemistry, algae and trophic status of an Andean acidic lake system of volcanic origin in Patagonia (Lake Caviahue)
The acidic caldera lake Caviahue (Patagonia, Argentina) and its main tributaries were studied on two dates during September 1998. The main results are: The acidity of the Lake Caviahue (pH: 2.56,Expand

High-resolution video monitoring of hematopoietic stem cells cultured in single-cell arrays identifies new features of self-renewal.
To search for new indicators of self-renewing hematopoietic stem cells (HSCs), highly purified populations were isolated from adult mouse marrow, micromanipulated into a specially designedExpand

Release rates and biological availability of phosphorus released from sediments receiving aquaculture wastes
Aquaculture is an increasingly significant user of freshwater resources in Scotland. In 1989, the total fish biomass produced in Scottish freshwater amounted to 7000 t. 50% of this total was rearedExpand

Aquaculture and biodiversity.
The impacts of aquaculture on biodiversity are rarely positive, sometimes neutral, but usually negative to some degree. Impacts arise from the consumption of resources, such as land (or space),Expand

Analyzing the impacts of plug-in electric vehicles on distribution networks in British Columbia
The impact of uncontrolled charging of plug-in electric vehicles (PEVs) on distribution networks is investigated using a probabilistic approach based on Monte Carlo simulations. A model simulatingExpand

Particle size distribution of wastes from freshwater fish farms
Waste water treatment on freshwater fish farms is problematic as waste material and water flows can vary greatly on a daily basis, and, in terms of effluent standards, fish farm effluent represents aExpand

PPARalpha agonists reduce 11beta-hydroxysteroid dehydrogenase type 1 in the liver.
11beta-hydroxysteroid dehydrogenase type 1 (11betaHSD1) is an enzyme that converts cortisone to the active glucocorticoid, cortisol. Cortisol-cortisone interconversion plays a key role in theExpand

Real-time fluorescence tracking of dynamic transgene variegation in stem cells.
Transgene variegation is caused by epigenetic switching between expressing and silent states. gamma-retrovirus vectors can be variegated in stem cells, but the dynamics of epigenetic remodelingExpand
