S-shaped curve threshold analysisTwo-dimensional modelThe evaluation of regional water resource carrying capacity has been repeatedly conducted to provide a scientific basis for the local water resource management and the sustainable development, in particular in the water-limited regions. However, the ...
Carrying Capacity of an Ecosystem Populations grow at a rate limited by the availability of the Earth’s resources. A population may grow at a faster rate and follow a J-shaped curve. When the birth rate surpasses the death rate of the species, this results in exponential growth. However, ...

(MTATP6-8993 T > G), the maximal respiration (Fig.5e) was significantly reduced by 34% when compared to the healthy control BJ-hiPSC. However, the spare respiratory capacity was not significantly different from the healthy control BJ-hiPSC, which indicated that the cells could overcome ...
1,293,528 discloses the use of a plurality of chain rings as an “inexpansible” bond to provide a pneumatic tire having a cross section under inflation to present a most advantageous width for weight carrying capacity and which will have only the minimum radial height necessary to provide ...
