The underlying mechanisms for screening disparities for immigrant women may lie in sociodemographic barriers, barriers rooted in the health care system, cultural or migration-related barriers or, most likely, some combination of the three [ 4, 17- 23].
The extent of rhizosphere interactions between Zhongyouza I and pai-tsai was controlled by different root barriers, or without barrier.
In general there are three major rate limiting steps or barriers for efficient Zn accumulation in rice grain: 1) soil-to-root barriers; 2) root-to-shoot barriers; and 3) barriers in loading Zn into grains.
In four-year-old jatropha intercropping, root barriers reduced yields 80% by limiting jatropha root access to soil moisture and nutrients in the maize plantings.
Institutional barriers identified, encompass organizational barriers rooted in organizational processes (system and process barriers) and the limited availability of resources.
Institutional barriers found encompass organizational barriers rooted in the organizational processes (system and process barriers) and the limited availability of resources.
But a rubber-root barrier is the only way to keep the plant's aggressive runners from colonizing the block.
On top of that a root barrier, polystyrene insulation, drain mat (resembling an upside down egg crate) for water retention and aeration and finally, 3 to 12 inches of soil mix, depending on the crop, like shallow-rooted mesclun, or deep-rooted tomatoes.
After slicing open the bags and emptying them into bins perched atop motorized buggies, workers ferried the mix — over and over again, making hundreds of trips — to the other side of the roof, where another group spread it out eight inches deep over layers of root barrier, felt and drainage material deployed to minimize the need to water and protect the skin of the roof.
Intercropping without root barrier and with leaf mulch produced the largest yields of 25 kg ha−1.
There was some evidence of an increased root barrier effect of the grass strips in areas with a compacted topsoil.
