The Energy Department has also evaluated the risk that fire could release radioactive elements that have contaminated the soil, grass, bushes and trees at its nuclear sites.
In ephemeral productions of great beauty and emotional power, a shape based on her own 4-foot-10-inch body is burned into wood, traced in blood, formed from mounds of soil, grass, gunpowder or flowers and shown floating on streams, erupting volcanically or otherwise merging with the landscape.
Hazardous radionuclides such as iodine-131, caesium 137, and other isotopes currently being released in the sea and air around Fukushima bio-concentrate at each step of various food chains (for example into algae, crustaceans, small fish, bigger fish, then humans; or soil, grass, cow's meat and milk, then humans).
In a gentler sequel, Tuqan depicts herself as a link in the chain of history: I ask nothing more Than to die in my country To dissolve and merge with the grass, To give life to a flower That a child of my country will pick, All I ask Is to remain in the bosom of my country As soil, Grass, A flower.
There was only a minor improvement for the other land cover classes (broadleaved forest, bare soil, grass and water).
Hyperspectral spectra of four common endmembers, bare soil, grass, tree, and shadow, were collected in situ, and images captured via video camera were interpreted into accurate areal ground cover fractions for evaluating the mixture models.
After the treatment application, we recorded the percentage ground cover of four categories, allowing for a sum higher than 100% due to overlapping layers; % bare soil, lawn grass, bunch grass, and forbs.
The concentration and exposure time-dependent potential toxicity of CeO2 NPs on soil microorganisms was examined by testing the activity of three enzymes urease, phosphatase, and β-glucosidase in a soil-grass microcosm system, and estimated through specific enzyme assays.
VIENNA, AUSTRIA--Whether their roots are ankle-deep in saltwater or toasting in superhot soils, grasses can tough out the weather.
Go to your local hardware store and buy soil and grass seeds (if you want the grass to look pretty you can pick up some flower seeds as well).
