Precision long-term measurements of beta-decay-rate ratios in a controlled environment
Physics Letters B, 2017 We report on measurements of relative beta-decay rates of Na-22, Cl-36, Co-60, Sr-90, Cs-137 monitored for more than one year. The radioactive samples are mounted in an automated sample changer that sequentially positions the five samples in turn, with ...

General decay for a nonlinear pseudo-parabolic equation with viscoelastic term
Demonstratio Mathematica, 2022 This work is concerned with a multi-dimensional viscoelastic pseudo-parabolic equation with critical Sobolev exponent. First, with some suitable conditions, we prove that the weak solution exists globally.

Decay rate of reindeer pellet-groups
Rangifer, 2008 Counting of animal faecal pellet groups to estimate habitat use and population densities is a well known method in wildlife research. Using pellet-group counts often require knowledge about the decay rate of the faeces.

On Global Well-Posedness and Temporal Decay for 3D Magnetic Induction Equations with Hall Effect
Mathematics, 2020 The main purpose of this paper is to study the global existence and uniqueness of solutions for three-dimensional incompressible magnetic induction equations with Hall effect provided that ∥u0∥H32+ε+∥b0∥H2 ...

On the decay rate of sunspots [PDF]
Geophysical Research Letters, 2003 We have analyzed the decay of 32 sunspots observed during the years 1988 through 2001 at the San Fernando Observatory (SFO). The data are from digital images obtained in the red (672 nm) with the Cartesian Full Disk Telescope No.1 (CFDT1). We find that the rate of decay is strongly correlated with the total sunspot area and the umbral to total area ...

Frontiers in Microbiology, 2019 For biogas-producing continuous stirred tank reactors, an increase in dilution rate increases the methane production rate as long as substrate input can be converted fully. However, higher dilution rates necessitate higher specific microbial growth rates,

The decay rate of orthopositronium [PDF]
AIP Conference Proceedings, 1991 We review recent measurements of the orthopositronium decay rate, λT, and present results of a new 230‐ppm measurement using the vacuum technique. It corroborates, at the 6.2 sigma level, the discrepancy between theory and a recent 200‐ppm measurement of λT in gases.
