Quark interactions inside baryons depend on the spin states of the quarks. We investigated the contribution of the spin–spin interactions of quarks in comparison with other factors necessary for diquark formation in baryons, concluding that the eff

Nuclear Medicine and with it, the production of radiopharmaceuticals, represent an increasingly important part of the global medical market. This market is estimated at over $3 billion per year and growing. In this study, we compare the current Brazi

Diquarks, or metastable clusters of two quarks inside baryons, are shown to be produced by angular momentum excitation. In baryons with a light quark and two heavy quarks with large angular momentum (L>2), the centrifugal barrier that appears in the

We analyze the dynamics of diquark formation in baryons containing one light and two heavy quarks. Due to the slower motion of the heavy quarks, we consider the motion of the light quark in a reference frame fixed in the two heavy ones. The potential

Summary The macroscopic aspects of moisture transmission in whey protein films were determined by measuring water vapour adsorption. A theoretical model was constructed in which two kinds of water vapour fluxes were considered: one originating from d

Summary We show that the moisture adsorption by a chocolate film is best described by a non-linear diffusion equation. We found an approximate analytical solution and determined the diffusion parameters by fitting this solution to experimental data.

The energy distribution of a “monoenergetic” and a “white” neutron source were determined with an NE 213 detector system by neutron time-of-flight spectroscopy and by the unfolding of the simultaneously measured scintillation pulse height spe

A technique to obtain neutron emission energy spectra above 2 MeV from (x,n) nuclear reactions using NE-213 liquid scintillator and a pulsed accelerator was investigated. After selection of the neutron light pulses both by pulse shape discrimination
