The transition from eco-harmful chemical processes to bio-based production of organics has been challenged by the complex nature fermentation processes. growth kinetics and modelling oxalic acid cassava whey Aspergillus niger (MW188538) was studied in a batch system. study fitted into Monod, Leudeking-Piret Andrews kinetic models. acid, reducing sugar, cell dry weights were determined according...

We propose a method to create a nontrivial Haldane phase in an atomic two-component Fermi gas loaded on a one-dimensional optical lattice with trap potential. The Haldane phase is naturally formed on a p-band Mott core in a wide range of the strong on-site repulsive interaction. The present proposal is composed of two steps, one of which is theoretical derivation of an effective 1D S=1 interact...

We study the entanglement structure and the topological edge states of the ground state of the spin-1/2 XXZ model with bond alternation. We employ parity-density matrix renormalization group with periodic boundary conditions. The finite-size scaling of Rényi entropies S2 and S∞ are used to construct the phase diagram of the system. The phase diagram displays three possible phases: Haldane type ...

We have analysed the dose-response curve for halothane and isoflurane according to the Monod-Wyman-Changeux (MWC) model. This model describes the nature of the physiological data reported by Wakamori, Ikemoto and Akaike for inhibitory Cl currents induced by GABA or glycine in dissociated rat brain neurones and by Herrington and colleagues for Ca2+ currents in clonal pituitary cells. With some a...

kinetics of single cell protein production from natural gas by a microorganism (a methylomonas sp.) was studied experimentally and by modeling at equal amount of air and natural gas. kinetic models of monod, moser, teissier, aiba, andrews, and noack were used for illustrating cell growth. methane and oxygen were considered as limited substrates with concentration in the range 2-10 mg/lit. death...

We study a spin-$\frac{1}{2}$ XXZ model with four-spin interaction on two-leg ladder. By means of effective field theory and matrix product state calculations, we obtain rich ground-state phase diagrams that consist eight distinct gapped phases. Four them exhibit spontaneous symmetry breaking either magnetic or valence-bond-solid (VBS) long-range order. The other four are featureless, i.e., the...

In this work, we focus on the mathematical analysis of the model of chemostat with enzymatic degradation of a substrate (organic matter) that can partly be under a solid form Simeonov and Stoyanov (2003). The study of this 3-step model is derived from a smaller order sub-model since some variables can be decoupled from the others. We study the existence and the stability of equilibrium points o...

The wave functions of the Haldane-Rezayi paired Hall state have been previously described by a non-unitary conformal eld theory with central charge c = ?2. Moreover, a relation with the c = 1 unitary Weyl fermion has been suggested. We construct the complete unitary theory and show that it consistently describes the edge excitations of the Haldane-Rezayi state. Actually, we show that the unitar...
