The existence of two separate lineages of Escherichia coli 0157:H7 has previously been reported, and research indicates that one of these lineages (lineage 1) might be more pathogenic toward human hosts. We postulated that the lineage more pathogenic expresses higher levels of Shiga toxin 2 (Stx2) than do the nonpathogenic lineage II. A comprehensive set of methodologies were used to investigat...

The accurate measurement of oxygen is essential to evaluate the effectiveness of tire suppressant agents and to model the dynamics of the suppression process. We employed tunable diode laser absorption spectroscopy (TDLAS) at 760nm to detect molecular oxygen. This technique has sensitivity to oxygen, minimal interference from other species, and capability of in-situ operation. Measurements were...

L-edge XANES of a series of gold (AuA12, AuGa and Au2Ag) and nickel (NiSb, Ni Fe NiA1, and NiAl ) intermetallic compounds have been measured. !?t6Ys f86%gYthat the LI1 I : edges of AuA12 and AuGa2 exhibit very intense whiteline indicating a sign$flcant depletion of d character at the Au site of these compounds. This observation is interpreted in terms of a mechanism in which s-d interplay deter...

Present status and pers ectives of further ex eriments on electron-impact excitation of a ! omic autoionizing s ? ates by the col.ncidence (e,2e) method are discussed on the basis of the current theoretical investigations in the Moscow-Dubna-Ulan-Bator group (Balashov, Cm-Crzhimailo, Lhagva, Iagunov,Strakhova). 1 . INTRODUCTION It was more than twenty years ago when it was shown that the coinci...
