Effect of conditions of extraction on solubility and composition of extracted humus substances


, : Effect of conditions of extraction on solubility and composition of extracted humus substances. Agrokhimiya, 10, 141-144

Increasing the temperature and the duration of standing with 0.1 N H2SO4, 0.1 N NaOH, or 0.1 M Na4P2O7 + 0.1 N NaOH increased the solubility of humus substances and altered the qualitative composition of the compounds extracted.

Expiratory muscle activity has been shown to occur in awake humans during lung inflation; however, whether this activity is dependent on consciousness is unclear. Therefore we measured abdominal muscle electromyograms (intramuscular electrodes) in...

IGF-I has a pivotal role in bone growth and could be one of the putative disease-modifier genes in AIS. Two SNPs in IGF-I gene promoter region were studied for any association with occurrence of AIS and for their effect on the curve severity among...
