Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...
Bacteria found in clarified ovine rumen fluid are capable of degradation of high-energy explosives such as RDX (Hexahydro-1,3,-trinitro‐1,3,5‐triazine) and HMX (Octahydro‐1,3,5,7‐tetranitro‐1,3,5,7-tetrazocine).
A simple, fast liquid-liquid extraction method was developed for studying hexahydro-1,3,5-trinitro-1,3,5 triazine (RDX) biodegradation using small sample volumes. The method was tested
in vitro with anaerobic incubations of RDX with whole rumen fluid (WRF) and a commercial S.
acetigenes strain in methanogenic media for RDX. Additionally, validation experiments were
conducted...
A new class of information intensive applications is emerging [Fuch82;
Ohsu82] for which neither Artificial Intelligence (AI) nor Database technologies
alone are well suited. Database systems do not provide the general inferential
capabilities required for problem solving, while AI techniques have not been
adapted to handle massive amounts of structured...
“Perennial ryegrass staggers” is a neurological condition characterized by muscular tremors and ataxia in livestock that ingest the indole diterpene lolitrem B from endophyte-infected perennial ryegrass. While the neurotoxic mechanism of action of ryegrass staggers has been defined, little is known about metabolic and other molecular processes that lolitrem B...
Accurate estimates of soil nitrogen (N) mineralization rate and timing are needed for refining N management practices. This paper describes a buried bag method that has been successfully included within agronomic field trials in the Pacific Northwest, USA. We have found this method to be technically simple and reproducible, and...
En los niños, el plomo puede causar daño cerebral.
Por eso puede ser que no haya ningún síntoma
inmediato después de la exposición del niño al
plomo; los efectos pueden tardar años en aparecer.
Los niños de entre 6 meses a 6 años de edad corren el
mayor riesgo. En...
Lead contamination of the environment is an important human health problem. This publication is designed to help homeowners evaluate and manage lead hazard in their landscape or garden. We explain:
• How soils get contaminated with lead
• How to test your soil for lead contamination
• How to reduce...
