Malting quality data were collected on malts from three barley (Hordeum vulgare L.) breeding program trials. We tried to identify causal polymorphisms in the Bmy1 intron III and coding regions for use in marker-assisted selection. Abundant malting qu

In retrospective radon measurements, the 22-y half life of (210)Pb is used as an advantage. (210)Pb is often considered to be relatively immobile in glass after alpha recoil implanted by (222)Rn progenies. The diffusion of (210)Pb could, however, lea

In recent years there has been increasing interest in radio-epidemiological techniques to retrospectively measure the radon dose exposure by determining the activity of 210Pb, the longest-lived 222Rn progeny, in glass surface layers. In this study th

Two-particle correlation functions, involving protons, deuterons, tritons, and α -particles, have been measured at very forward angles ( 0.7 ° ⩽ θ lab ⩽ 7 ° ), in order to study projectile-like fragment (PLF) emission in E / A = 44 and 77 MeV

Small-angle two-particle correlation functions, involving neutrons and protons, have been measured for E/A = 61 MeV Ar + Sn-112,Sn-124 collisions, i.e. systems similar in size but with different isospin asymmetry. The correlation strength of neutron-

Finite size effects on cluster distributions are investigated within Ising and Fisher's Droplet Model. Fixed magnetization calculations suggest that the introduction of a complement correction of the emitting system is a promising approach for finite

We present the details of an experiment on light particle interferometry. In particular, we focus on a time-of-flight technique which uses a cyclotron RF signal as a start and a liquid scintillator time signal as a stop, to measure neutron energy in
