BACKGROUND Despite its semi-commercial status, ethanol production from lignocellulosics presents many complexities not yet fully solved. Since the pretreatment stage has been recognized as a complex and yield-determining step, it has been extensively studied. However, economic success of the production process also requires optimization of the biochemical conversion stage. This work addresses t...

A vast majority of material processing in industry involves homogeneous phase reactions. These reactions are carried out in batch mode as well as continuous mode. The empty tubular reactors are widely used reactor systems for continuous processing in chemical and allied industry. The heat effects due to these reactions necessitate the use of some heat removal/addition system with these reactors...

A model of temperature dynamics was developed as part of a general model of activated-sludge reactors. Transport of heat was described by the one-dimensional, advection-dispersion equation, with a source term based on a theoretical heat balance over the reactor. The model was compared to several reference models, including a tanks-in-series model and the dispersion model with heat components ne...

KamLAND has measured the flux of nu;(e)'s from distant nuclear reactors. We find fewer nu;(e) events than expected from standard assumptions about nu;(e) propagation at the 99.95% C.L. In a 162 ton.yr exposure the ratio of the observed inverse beta-decay events to the expected number without nu;(e) disappearance is 0.611+/-0.085(stat)+/-0.041(syst) for nu;(e) energies >3.4 MeV. In the context o...

Membrane reactors are currently under extensive research and development. Hardly any concept however is realized yet in practice. Frequently, forgotten as membrane reactors are electro-catalyic membrane reactors where electrodes perform chemical conversations and membranes separate the locations of conversion. In this chapter we extensively describe a technology where the membrane itself is cat...

In a previous paper, we proposed that QCD gas may be possible candidate for the general theory of gravity (GR) ether comprised ud~du~ exotic mesons. A method to determine effective mass meson and Friedmann-Robertson-Walker (FRW) metric scale factor equation state dimensionless parameter, w, by measuring pseudo-first order ? decay rates expected inversely proportional atmospheric density was giv...
