The influence of sulfate-reducing bacteria (SRB) on the corrosion behaviors X80 pipeline steel was investigated in a soil environment by electrochemical techniques and surface analysis. It found that SRB grew well acidic further attached to coupon surface, resulting microbiologically influenced (MIC) steel. process significantly affected biofilm surface. Steel inhibited highly bioactive at earl...

* Rates are per 100,000 population. † Suicides are identified with International Classification of Diseases (ICD) 8th Revision codes E950–E959 for 1975–1978; ICD 9th revision codes E950–E959 for 1979–1998; and ICD 10th revision codes U03, X60–X84 and Y87.0 for 1999–2015. In 1975, in the United States, there were 1,289 suicides among males and 305 suicides among females aged 15–19 years. In 2015...

Electronic structure of X60 molecules (X=C, Si) is considered in terms of 60 odd electrons and spin-dependent interaction between them. Conditions for the electrons to be excluded from the covalent pairing are discussed. A computational spin-polarized quantumchemical scheme is suggested to evaluate four parameters (energy of radicalization, exchange integral, atom spin density, and squared spin...
