This report is part of a serial study applying stable isotope labelling to rice microcosms to track the utilization of recently photosynthesized carbon by active microbiota in the rhizosphere. The objective of the present study was to apply phospholipid fatty acid-based stable isotope probing (PLFA-SIP) to detect the spatial variation of active microorganisms associated with rhizosphere carbon ...

Studying chemical reactions in an environment that closely mimics the system’s natural operating conditions can offer crucial insights into dynamic oxidation processes. Transmission Electron Microscopes (TEMs) and X-ray Nanoprobes allow use of imaging spectroscopy to access nanoscale structural information about these However, controlled constraints make design implementation situ sample enviro...

Using data from the 2010 Colombia Demographic and Health Survey and of the National Survey of the Nutritional Situation in Colombia (ENDS-ENSIN), we analyzed the evolution of the height for the Colombian birth cohorts in the period 1946-1992 by ethnic groups defined through self-classification. We find that there are statistically significant differences in height between the ethnic groups cons...

Using cross country regressions, this paper constructs a novel distance-to-frontier metric for tracking broad socio-economic inequality (including access of the poor to health infrastructure) over time for individual countries. Given the unavailability of reliable and consistent direct measures of inequality for most poor countries, especially related to nonincome aspects of living standards, t...
