In this research, influence of adding Li2CO3 (at 0%, 2%, 4%, 6%) on electrical and magnetic properties of [Formula: see text][Formula: see text]Fe2O4 (with 60% Ni and 40% Mg) ferrite has been studied. The samples are prepared by solid state reaction method and sintered at 1300∘C for 6[Formula: see text]h. X-ray diffraction (XRD) patterns show the samples belong to single-phase cubic structure without any impurity phase. The magnetic properties (saturation magnetization and coercivity) of the samples have been investigated by VSM and found that the higher concentration of Li2CO3 reduces the hysteresis loss. DC resistivity increases with Li2CO3 contents whereas it decreases initially and then becomes constant at lower value with temperature which indicates that the studied samples are semiconductor. The dielectric dispersion occurs at a low-frequency regime and the loss peaks are formed in a higher frequency regime, which are due to the presence of resonance between applied frequency and hopping frequency of charge carriers. Notably, the loss peaks are shifted to the lower frequency with Li2CO3 additions.

ABSTRACT As a consequence of being diploid, retroviruses have a high recombination rate. Naturally occurring retroviruses contain two repeat sequences (R regions) flanking either end of their RNA genomes, and recombination between these two R regions occurs at a high rate. We deduced that recombination may occur between two sequences within the same RNA molecule (intramolecular) as well as between sequences present within two separate RNA molecules (intermolecular). Intramolecular recombination would usually result in a deletion within the progeny provirus. In this report, we demonstrate that intramolecular recombination between two identical sequences occurred within a chimeric RNA vector. In addition, high rates of recombination between two identical sequences within the same RNA molecule resulted mostly from intramolecular recombination.
