Although Inner Mongolia has a vast territory with a sparse population, the pressure of the social environment brought to it by the increasing population is still very great, because more than 80% of its territory is arid and half arid desert, its ecological environment very weak, the bearing capacity of its land small, and its regional economy not developed.
In the course of the society development,problems of the population scale,as well as the bearing capacity of the environment and economy become more and more urgent and severe,and arouse lots of society and security problems.
At present, our country is carrying the maximum populationwith the most rigorous resources conditions in history. The issueon the land resources population carrying capacity was paidclose attention to.
Reported QSRR models are critically reviewed, bearing in mind their statistical predictability physical meaning.
Synthesis and evaluation of five different N,N-disubstituted aminoethanol ester derivatives of indomethacin bearing structural resemblance to the aminoethanol ester class of anticholinergics are reported herein.
Influence of the Mechanical Seals on the Dynamic Performance of Rotor-Bearing Systems
In this paper, to consider the effects of mechanical seals, a lumped-mass model and the transfer matrix method are used to establish the equations for the dynamics performance of rotor-bearing system.
To check the response of the rotor-bearing system under unbalance motivation, the Gauss method is used to calculate the dynamic response of the constrained vibration.
Compounds Ia-Ih were hydrogenated with Pd-C to give IIa-IIh, and their hypoglycemic activity was evaluated with a glucose oxidase kit and insulin load test on normal mice.
A complex load shading parameter is set up to describe various load shading schemes.
The imaginary part of the load shading parameter describes the states of switches of load shading schemes while the real part is the corresponding amount of shaded load.
The procedure to search the operation with the least amount of shaded load for a feeder and a connected domain are detailed.
Results of analysis show that the direct load shading scheme under the most balanced topology is not always the optimal scheme.
The persistence of the infectious disease and disease-related deaths can lead to a new equilibrium population size below the carrying capacity.
Chitosan-sodium alginate-hemoglobin microcapsules are expected to become an artificial oxygen-carrying therapeutic agent with sustained release for intravenous injection.
Results indicate that the annual accumulation of different forest litters is about 6.80-20.21 t/hm2 and the maximum water carrying capacity ranges from 1.8 to 4.6 mm.
Among them the water carrying abilities of the litter of Lithocarpus glabra and natural deciduous forests are larger than that of Pinus massoniana.
A power function relationship exists between the accumulated water-carrying volume and time.
With a loading molar ratio of Ag/Ti = 0.135 in TiO2 film, the maximum catalytic efficiency was observed.
The effects of experimental variables such as the buffer solutions, pH and the amount of loading enzyme were investigated for the optimum analytical performance.
The loading efficiency of porcine hemoglobin (pHb) in microcapsules is more than 90%.
The oxidation current of methanol on the Pt-CNTs/GC electrode did not always increase with the increase in the amount of Pt loading.
The result indicates that there is an optimal Pt loading for methanol oxidation.
