Methane hydrates and biohydrogen are two disparate subjects that are of interest in the growing field of alternative energy research. However, before commercial use becomes a viable option, each has challenges that need to be overcome. Methane hydrates require large investments of time and capital to locate. In this thesis,...
Traffic simulators are often utilized when researching turfgrass wear tolerance and recovery. However, the availability of a durable traffic simulator capable of producing dynamic force is limited. Therefore, the objectives of this research were to: 1) evaluate a novel traffic simulator with improved durability and capable of producing dynamic force...
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...
The fertilizer value of anaerobically-digested, dewatered biosolids in dryland cereal cropping systems was evaluated at six locations in central and eastern Washington (25 to 35 cm annual precipitation zone). Biosolids were applied at rates of 3 to 20 Mg/ha (approximately 150 to 900 kg N/ha). We measured increases in soil...
Agencies in the US with oversight for marine renewable energy development have idealistically sought space where this new use might proceed unhindered by other uses. Despite experiential evidence of spatial overlap among existing ocean uses, a lack of documentation makes the identification of potential space-use conflicts, communication among existing 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...
Temperature, salinity, density and turbulent dissipation profiles measured using the Rapid Sampling Vertical Profiler during the Coastal Transition Zone Experiment, July 1988.
The dynamic watershed acid-base chemistry model of acidification of groundwater in catchments (MAGIC) was used to calculate target loads (TLs) of atmospheric sulfur and nitrogen deposition expected to be protective of aquatic health in lakes in the Adirondack ecoregion of New York. The TLs were calculated for two future dates...
Eukaryotes contain a diversified set of small RNA-guided pathways that control genes, repeated sequences, and viruses at the transcriptional and posttranscriptional levels. Genome-wide profiles and analyses of small RNAs, particularly the large class of 24-nucleotide (nt) short interfering RNAs (siRNAs), were done for wild-type Arabidopsis thaliana and silencing pathway mutants...
