Combining stable isotope ratios with elemental concentrations to improve the estimation of terrestrial carnivore diets

Global Ecology and Conservation, 2023
Stable isotopes of animal tissue have been used to estimate diet for many consumer species and places, but the ability to assign contributions to all food items is limited by the number of tracers used, and the separation of the tracer data among the ...

Introducing a Precise System for Determining Volume Percentages Independent of Scale Thickness and Type of Flow Regime

Mathematics, 2022
When fluids flow into the pipes, the materials in them cause deposits to form inside the pipes over time, which is a threat to the efficiency of the equipment and their depreciation.

TITAN's Digital RFQ Ion Beam Cooler and Buncher, Operation and Performance

, 2012
We present a description of the Radio Frequency Quadrupole (RFQ) ion trap built as part of the TITAN facility. It consists of a gas-filled, segmented, linear Paul trap and is the first stage of the TITAN setup with the purpose of cooling and bunching ...

Bound states of 3He at the edge of a 4He drop on a cesium surface [PDF]

, 2003
We show that small amounts of 3He atoms, added to a 4He drop deposited on a flat cesium surface at zero temperature, populate bound states localized at the contact line. These edge states show up for drops large enough to develop well defined surface and

Short-term dispersal of Fukushima-derived radionuclides off Japan: modeling efforts and model-data intercomparison [PDF]

Biogeosciences, 2013
The Great East Japan Earthquake and tsunami that caused a loss of power at the Fukushima nuclear power plants (FNPP) resulted in emission of radioactive isotopes into the atmosphere and the ocean.

Atomic Parity Violation : Principles, Recent Results, Present Motivations

, 2005
We review the progress made in the determination of the weak charge, Q\_w, of the cesium nucleus which raises the status of Atomic Parity Violation measurements to that of a precision electroweak test.

Ultrasensitive detection of radioactive cesium isotopes using a magneto-optical trap [PDF]

SPIE Proceedings, 2002
We report the first magneto-optical trapping of mdioactive {sup 135}Cs and {sup 137}Cs and a promising means for detecting these isotopes to ullrasensilive lcvels by a system coupling the magneto-optical trap (MOT) to a mass separator. The mass separator efficiently delivers a 20 kV ion beam of either isotope into a quartzcube MOT cell having in one ...

Optimization of the Solidification Method of High-Level Waste for Increasing the Thermal Stability of the Magnesium Potassium Phosphate Compound

Energies, 2020
The key task in the solidification of high-level waste (HLW) into a magnesium potassium phosphate (MPP) compound is the immobilization of mobile cesium isotopes, the activity of which provides the main contribution to the total HLW activity. In addition,
