Heterogeneous mixture

Environment degradation is the major threat confronting the world and rampant use of chemical fertilizer contribute largely to the deterioration of the environment. Soil fertility highly affected due to imbalance use of fertilizers that has deep impact on productivity and soil degradation. This study gives an idea to identification of effects of variable diet on growth and reproduction of Eisenia fetida which leads to enhancement of soil quality.

Petroleum mixtures consist primarily of relatively unreactive complex hydrocarbons covering a wide boiling range. Such mixtures are difficult to separate by most analytical techniques. Therefore, the petroleum industry has for many years played a leading role in the development of chromatographic methods of analysis. Since the last book specifically concerned with chromatographic analysis of petroleum appeared 15 years ago, numerous advances have been made including developments in liquid and supercritical fluid chromatography, ...

Structural elucidation of the lipopolysaccharide (LPS) from three nontypeable Haemophilus influenzaeclinical isolates, 1209, 1207 and 1233 was achieved using NMR spectro-scopy and ESI-MS on O-deacylated LPS and core oligo-saccharide (OS) material as well as ESI-MS n on permethylated dephosphorylated OS. It was found that the organisms expressed a tremendous heterogeneous glyco-form mixture resulting from the variable length of the OS chains attached to the common structural element of H.
