Development of an Antibiotic Resistance Free Bivalent Vaccine Against Swine Brucellosis and Swine Influenza
… over-expressed Brucella derived antigens SOD, L7/L12 and WboA in three different constructs. Against a virulent challenge of B. suis, the candidate vaccine strain over-expressing both SOD and WboA protected mice more significantly than the control group and was also found to be better protective …

Nanocrystalline Fe-Pt alloys: phase transformations, structure and magnetism
… case of the Fe-rich and Pt-rich compositions, L12 Fe3Pt and FePt3 phases, respectively. Whereas in Pt-rich alloys the decoupling effect of the FePt3 phase leads to coercivity improvement, in Fe-rich nanocomposites a peculiar nanometer scale multilayer structure gives rise to remanence …
