Viscosity loss of high-molecular-weight partially hydrolyzed polyacrylamide (HPAM) solution was observed in a water injection pipeline before being injected into subterranean oil wells. In order to investigate the possible involvement of microorganisms in HPAM viscosity loss, both bacterial and archaeal community compositions of four samples collected from(More)
The title compound, [CoBr(2)(C(18)H(12)N(6)S)], is a mononuclear complex in which a twofold rotation axis passes through the Co and S atoms. The Co(II) center is six-coordinated by four N atoms from one bis-[4-(2-pyrid-yl)pyrimidin-2-yl] sulfide (L) ligand and two bromide anions, forming an octa-hedral coordination geometry, where the four donor N atoms are(More)
