Reduced heat flow in light water (H2O) due to heavy water (D2O)

open access: yes, 2008
The flow of heat, from top to bottom, in a column of light water can be decreased by over 1000% with the addition of heavy water. A column of light water cools from 25 C to 0 C in 11 hours, however, with the addition of heavy water it takes more than 100

Ion Source Complementarity for Characterization of Complex Organic Mixtures Using Fourier Transform Mass Spectrometry: A Review

open access: yesMass Spectrometry Reviews, Volume 44, Issue 5, Page 808-829, September/October 2025.
ABSTRACT Complex organic mixtures are found in many areas of research, such as energy, environment, health, planetology, and cultural heritage, to name but a few. However, due to their complex chemical composition, which holds an extensive potential of information at the molecular level, their molecular characterization is challenging.

Rydberg-Klein-Rees 1-Sigma-positive potential curve turning points for the isotopes of carbon monoxide [PDF]

open access: yes
First order RKR turning points were computed for (C-12)O16, (C-12)O17, (C-13)O16, (C-12)O18, and (C-13)O18 for vibrational levels up to v = 40. These turning points should be useful in the numerical computation of matrix elements of powers of the ...

Isotope effect on superconductivity in Josephson coupled stripes in underdoped cuprates

open access: yes, 2007
Inelastic neutron scattering data for YBaCuO as well as for LaSrCuO indicate incommensurate neutron scattering peaks with incommensuration $\delta(x)$ away from the $(\pi,\pi)$ point. $T_c(x)$ can be replotted as a linear function of the incommensuration

Dynamics of Collembola ecomorphological groups within a no‐till arable system

open access: yesAgricultural and Forest Entomology, Volume 27, Issue 3, Page 357-368, August 2025.
Abstract Collembolan ecomorphological groups (i.e., epiedaphic, hemiedaphic and euedaphic) have been proposed as bioindicators of soil health with potential to be applied in agricultural systems. While some studies have investigated disturbance gradients, there is a lack of monitoring studies showing trends over time evaluating changes in management ...

The Effect of Location on the Value of Ornamental Trees Using the Example of a Green Space in Lublin

open access: yesReal Estate Management and Valuation, 2019
This paper examines and identifies, using a specific example, how the location of trees influences their value. For the valuation of trees outside a forest area, appraisers often employ methods recommended for estimating forest stands, which ...

Exact Polynomial Eigenmodes for Homogeneous Spherical 3-Manifolds

open access: yes, 2006
Observational data hints at a finite universe, with spherical manifolds such as the Poincare dodecahedral space tentatively providing the best fit. Simulating the physics of a model universe requires knowing the eigenmodes of the Laplace operator on the ...
