The ratio 1∕(1 + ecol,j) determines the fraction of the feasible output, which is the farm's eco-effi- ciency in the interval [0;1] . The following relationship holds: eco-efficiency to the system frontier equals the meta-technology ratio (MTR) multiplied by group-specific eco-effi...
The magnetite nanoparticles were synthesized using a co-precipitation method; they were synthesized by mixing ferric chloride FeCl3·7H2O and FeSO4·7H2O with ratio (1:2) in deionized water through a three-neck flask. The nitrogen purged was connected with the solution. NaOH solution was added ...
Afterward, except for a peak (0.52) at 4000 m ∼ 5000 m, the RSEI average value decreases with increasing altitude; Fig. 9b shows that the slope of the Yangtze River Basin is inversely proportional to the area ratio. The area accounts for the largest proportion (64.9%) when the slope ...
A PEMFC-CHP system installed in Yazd, Iran was configured by optimization with considering the highest unified operation to reduce the carbon dioxide emission ratio [9]. The domestic fuel cell CHP system for a kilowatt (kW) unit is widely explored [31] while the CHP system for a megawatt (...
In i) and iii), directional selection is revealed by the distribution of the ratio of the genetic distance by heterozygicity (FST/He), whereas in ii), the genetic distance among populations is decomposed in two components: a population-specific component (Beta) shared by all loci and a ...
Nonetheless, the ratio of phage genes found in the deep Mediterranean at 3000 m (Martin-Cuadrado et al., 2007) was higher compared with the North Atlantic at 700 m and 4000 m. In our case, both characteristics might reflect a more strict association to particulate material and relatively ...
