Comparisons among studies are difficult due to the selection of different indicators on limitations and variations in wording and scales.
This facilitated identification of underserved areas and approximate distance as an independent indicator of limitation to access.
Health status was measured considering three subjective indicators of health: limitations, self-analysis of health, and self-satisfaction with health.
Several of these genes including FBP1 and STL1, as well as JEN1, ODC1, SFC1 and ATO2 have already been identified as being either induced under carbon limitation or being specific indicators of carbon limitation in yeast cultures [ 13], consistent with our own data.
Several motor tasks have been designated as potential indicators of mobility limitation.
However, N addition increased two indicators of C-limitation significantly (i.e., activity of β-D-glucosidase and vector length), both of which indicated that N addition aggravated microbial C-limitation.
In this study we analyze indicators of phosphorus limitation including phosphorus concentrations, phosphorus to nitrogen, and carbon ratios, oxygen isotope ratios of phosphate in vegetation, and phosphatase enzyme activity in soil to shed light on potential effects of climate change on phosphorus availability to grassland vegetation.
A study of the stoichiometry of exoenzymes concluded that increased C P ratios and decreased microbial growth efficiencies are indicators of nutrient limitation (Sinsabaugh et al.2009).2009
The methodological approach applied in the current study is easily transferable to other adverse environmental conditions, e.g. by selecting indicators of moisture-limitation.
Possibility of using such common type of indicators (limitations of physical activity) should be considered in epidemiological studies, such as the epidemiology of infection and the occurrence of multi-drug resistant organisms.
