Journal of Geophysical Research: Solid Earth, Volume 128, Issue 8, August 2023., 2023 Abstract Over the years, it has been clear to seismologists that the crustal structure beneath Mexico City is highly complex. This fact may influence the seismic waves' behavior when traveling through it. Consequently, many studies have been done to understand this crustal structure.

Analysis of plant secondary metabolism using stable isotope‐labelled precursors
Phytochemical Analysis, Volume 32, Issue 1, Page 62-68, January/February 2021., 2021 Abstract Introduction Analysis of biochemical pathways typically involves feeding a labelled precursor to an organism, and then monitoring the metabolic fate of the label. Initial studies used radioisotopes as a label and then monitored radioactivity in the metabolic products.

Airborne geoid determination [PDF]
Earth, Planets and Space, 2014 Airborne geoid mapping techniques may provide the opportunity to improve the geoid over vast areas of the Earth, such as polar areas, tropical jungles and mountainous areas, and provide an accurate “seam-less” geoid model across most coastal regions. Determination of the geoid by airborne methods relies on the development of airborne gravimetry, which ...

Geoid or Quasi-Geoid? A Short Comparison
, 2023 AbstractThis article is a short introduction to the debate on choosing the geoid and orthometric heights or the quasi-geoid and normal heights as the vertical coordinate system. It mainly compiles some more or less already known facts for comparing the two systems.

BioMed Research International, Volume 2014, Issue 1, 2014., 2014 The in vitro and in silico analysis of Rubus fairholmianus acetone extract for antioxidant, antiproliferative, and anti‐inflammatory activity led to the isolation of six compounds. Amongst all the six isolated compounds tested, 1‐(2‐hydroxyphenyl)‐4‐methylpentan‐1‐one (compound 1) and 2‐[(3‐methylbutoxy) carbonyl] benzoic acid (compound 2) were found ...
