A flotation device was used to navigate around wetlands where thick woody vegetation and/or deep water impeded effective monitoring from the shore.
But those hopes quickly sank as water shortages impeded growth and as chain stores like Kmart and Wal-Mart opened in towns, helping them grow but draining business from smaller communities with stores that could not compete.
These phenolic compounds acidify the water and impede decomposition of organic matter leading to peat accretion.
The higher basicity of 2,6-diaminopurine, p Ka 5.2, leads to more protonation at neutral pH, increasing its hydrophilicity and interaction with water, thereby impeding its interaction with its complementary partner.
We hypothesize that if low temperature impedes water uptake then less soil water would be removed by northern than by southern-selected cultivars.
That has always irritated the Galápagos's 16,000 residents, who must now also worry about befouled waters further impeding their livelihood.
If the US allows China to stake out control over international waters and impede the freedom of navigation in the region, then it opens the doors for China making similar claims [elsewhere], or other countries making similar claims," Davis explained.
Excessive tillage leaves the soil susceptible to crusting, impedes water intake, increases runoff, and thus reduces water storage for crop use.
Electrode materials efficiency and stability are two indispensable bottlenecks in solar-driven water splitting which impedes its large-scale productions.
