Only three mass ratios were associated with the inoculated drywall at High 95% ERH: 77.94 (FDR p=0.04), 97.95 (FDR p=0.04) and 314.11 (FDR p=0.04), though the chemical formula and compound for these masses are undetermined. However, certain compounds that are likely mVOCs such as C2H6...
SNA15896. Based on their HR-MS data, the molecular formulae of the SW-163 derivatives were determined (3: C52H60N10O14S2;8) 4: C53H62N10O14S2; 5: C54H64N10O14S2;8) 6: C55H66N10O14S2; 7: C56H68- N10O14S2). These data show that the difference among these homologs ...

Relative Sensitivity Factors (RSFs) for the rare earth elements Ce, Nd, Sm, Eu, Gd, Dy, Er, and Lu have been determined in U3O6-graphite and pure graphite matrices under similar experimental conditions employing Spark Source Mass Spectrometry (SSMS) with electrical detection system in magnetic...
It remains to be seen whether the world can maintain its linguistic( 语言的) and cultural diversity in the centuries ahead Many powerful forces appear to work against it: Population growth, which pushes migrant populations into the world's last isolated locations, mass tourism; global...
An assembly mixes and kneads a viscous mass of paste, and has two parallel shafts (3, 6) rotating in the same direction and fitted with mixer blades set at a pitch angle alpha. The position of one of the shafts (3, 6) may be adjusted with respect to the circumference of the other ...
