Near Surface Geophysics, EarlyView.Abstract A better understanding of the near‐surface aquifer system of the Caxambu Water Park, located in the Minas Gerais State, Brazil, has been achieved. The study aimed to identify groundwater reservoirs and flow patterns and contribute to the hydrogeological conceptual model using a multi‐scale geophysical approach.

Determination of strontium isotope ratios in plant samples by wet ashing digestion
Results in Earth SciencesStrontium isotope provenance analysis has been widely applied across multiple disciplines, including archaeology, food science, and forensics. The establishment of bioavailable ⁸⁷Sr/⁸⁶Sr maps, known as isoscapes, which rely on a substantial number of ...

Spectroscopy of $^{87}\text{Sr}$ triplet Rydberg states
, 2018 A combined experimental and theoretical spectroscopic study of high-$n$, ${30 \lesssim n \lesssim 100}$, triplet $\text{S}$ and $\text{D}$ Rydberg states in $^{87}\text{Sr}$ is presented. $^{87}\text{Sr}$ has a large nuclear spin, ${I=9/2}$, and at high-$

A Review of Bioarcheological Investigations in Iron Age Cambodia
International Journal of Osteoarchaeology, EarlyView.ABSTRACT Archeological research within Cambodia is quite extensive, with significant projects led by both Cambodian archeologists and international researchers alike. Many of these projects have uncovered human skeletal remains. This article reviews archeological human skeletal studies in Cambodia, synthesizing published and unpublished data, primarily

Iowa Population Exposures to Metals and Metalloids in Well Water
Environmental Toxicology, EarlyView.ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions
X-Ray Spectrometry, EarlyView.ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244Cm$$ {}^{244}\mathrm{Cm} $$ sources, and come with severe concerns on radiation safety and ...

Methods in Ecology and Evolution, EarlyView.Abstract Environmental tracers, including both elemental concentrations and isotope ratios, are widely used to reconstruct the movement patterns of animals throughout landscapes. The methodology involves creating a map that describes the distribution of the environmental tracer across the landscape, an isoscape and then matching the values of the same ...

Repumping and spectroscopy of laser-cooled Sr atoms using the (5s5p)3P2 - (5s4d)3D2 transition
, 2009 We describe repumping and spectroscopy of laser-cooled strontium (Sr) atoms using the (5s5p)3P2 - (5s4d)3D2 transition. Atom number in a magneto-optical trap is enhanced by driving this transition because Sr atoms that have decayed into the (5s5p)3P2 ...
