This paper assesses how considering variation in DOC availability and cell maintenance in bacterial models affects Bacterial Growth Efficiency (BGE) estimations. For this purpose, we conducted two biodegradation experiments simultaneously. In experiment one, a given amount of substrate was added to the culture at the start of the experiment whilst in experiment two, the same amount of substrate...

The original observation of Meyer Jackson ~ that nicotinic acetylcholine receptor (nAChR) channels may open spontaneously with the same intrinsic conductance and ion selectivity as the acetylcholine-gated channels provides strong support in favour of the Monod-Wyman-Changeux theory 2. It illustrates the interconversion of the protein between discrete conformations before ligand binding. In effe...

Repair rather than segregation of damage is the optimal unicellular aging strategy Model equations. In all cases, growth of active protein depends on substrate concentration S following Monod kinetics: (). (1) If repair of damaged protein takes place, the rate of repair is: (). (2) Basic model: damaged protein inert, and not repaired:

Despite significant advances in the understanding of lung cancer biology, the prognosis of cancer patients remains poor. Part of the failure of anticancer therapy is due to intratumoral heterogeneity in these patients that limits the efficacy of single agents. Therefore, there is an urgent need for new anticancer drugs or drug combination regimens that possess increased activity against all cel...

In this paper mathematical models of the composting process are examined and their performance evaluated. Mathematical models of the composting process have been derived from both energy and mass balance considerations, with solutions typically derived in time, and in some cases, spatially. Both lumped and distributed parameter models have been reported, with lumped parameter models presently p...

In this paper, we have studied the diffusive predator-prey model with Monod-Haldane functional response. The stability of the positive equilibrium and the existence of Hopf bifurcation are investigated by analyzing the distribution of eigenvalues without diffusion. We also study the spatially homogeneous and non-homogeneous periodic solutions through all parameters of the system which are spati...
