Purification and characterization of surfactant-stable protease from Bacillus lichenformis: A potential additive for laundry detergent by Mardina, Vivi, Yusof, Faridah

“…The enzyme was stable at temperature range of 35 oC to 65 oC and also at pH 6.0 and 7.0 for 60 min. The presence of Mn2+ and Ca2+ ions in the produced protease stimulated strongly the activity of the enzyme by 176.65% and 119.07% respectively, while inhibitory effects were found in the presence of Cu2+, Zn2+, Mg2+, and EDTA. …”

Two Potts Models on Cayley Tree of Arbitrary Order by Ganikhodjaev, Nasir, Nawi, Ashraf Mohamed, Rodzhan, Mohd Hirzie

“…On a Cayley tree of arbitrary order k we consider two different Potts models with competing nearest-neighbour interactions J1 and next-nearest-neighbour interactions Jp and Jo, where coupling Jp corresponds to interaction of spins belonging to the same branch of the tree (prolonged) and coupling Jo corresponds to interaction of spins belonging to the same shell of the tree (one-level) and find for each model in addition to the expected paramagnetic, ferromagnetic and antiferromagnetic phases, an intermediate range of coupling values where the local magnetization has chaotic oscillatory glass-like behaviour. …”
