BACKGROUND During strategic planning of a biogas plant, the local availability of resources for start-up and operation should be taken into consideration for a cost-efficient process. Because most bioethanol/sugar industries in Brazil are located in remote areas, the use of fresh cattle manure from local farms could be a solution for the inoculation of the biogas process. This study investigate...

Abstract: In this paper, we investigate the non-cooperative reaction-diffusion model of nuclear reactors subject to the homogeneous Neumann boundary condition. By establishing appropriate Lyapunov functions, we prove the global stability of the unique positive constant equilibrium solution.

Giant vesicles (GVs) are artificial chemical systems largely used as cell models [1-3], since they are micrometer-sized closed compartments bounded by a semi-permeable membrane, which in turn is composed by self-assembling amphiphiles. By opportunely engineering the lipid membrane and by entrapping cascade-reaction enzymes inside GVs, it comes possible to design micro-sized reactors where metab...

BACKGROUND The microbial community in a biogas reactor greatly influences the process performance. However, only the effects of deterministic factors (such as temperature and hydraulic retention time (HRT)) on the microbial community and performance have been investigated in biogas reactors. Little is known about the manner in which stochastic factors (for example, stochastic birth, death, colo...
