In this paper, we study the stability of the nonlinear hybrid system describing the concentrations of extracellular and intracellular substances in the process of bio-dissimilation of glycerol to 1,3-propanediol. We prove an asymptotical stability lemma in nonlinear impulsive hybrid systems and obtain the strict stability and uniformly asymptotical stability for the nonlinear hybrid system. The...

In this paper, I will give a detailed account of vowel harmony, disharmony, dissimilation, and elision in Yucatec Maya. These phenomena provide insights for the treatment of assimilation in Optimality Theory (Prince & Smolensky 1993). The theoretical topics to be dealt with are (i) an adequate formalisation of phonological feature assimilation within Correspondence Theory (McCarthy & Prince 199...

A mixture of L-(U-14C) amino acids was added to cultures of 11 strains of rumen anaerobic fungi belonging to Neocallimastix frontalis, Neocallimastix joyonii, Sphaeromonas communis and Piromonas communis. Fungi were grown in a complex medium with glucose for 4 days. The radioactivity was found in cellular protein (27.7-65.3% of the total radioactivity recovered), lactate (16.9-41.8%), volatile ...

SEPTICITY WITHIN A sewerage system occurs when microorganisms present in sewage and adhering to submerged surfaces have utilised all the dissolved oxygen and any nitrates that may be present in the sewage (derived from ground-water infiltration or present in the water supply). When anaerobic conditions have developed, bacteria in the sewage reduce the organic compounds of sulphur to sulphide an...

The stochastic counterpart to the deterministic description of continuous fermentation with ordinary differential equation is investigated in the process of glycerol bio-dissimilation to 1,3-propanediol by Klebsiella pneumoniae. We briefly discuss the continuous fermentation process driven by three-dimensional Brownian motion and Lipschitz coefficients, which is suitable for the factual ferment...
