Can microbial growth yield be estimated using simple thermodynamic analogies to technical processes?

In view of the prime importance of the biomass yield in microbial growth for research, for environmental and for industrial applications some thermodynamic concepts are reviewed that were developed over the years in order to understand the large variations ...

Enzyme States Allow Identification of Rate-Limiting Steps

Vassily Hatzimanikatis, Ljubisa Miskovic

A precise quantification of the effect of perturbations in a metabolic network depends on explicit knowledge of the kinetic properties of the enzymes of the individual reactions. However, a comprehensive knowledge of enzymes kinetics in a metabolic network ...

A path integral formalism of DNA looping probability

Ludovica Cotta-Ramusino

In this thesis we describe a path integral formalism to evaluate approximations to the probability density function for the location and orientation of one end of a continuum polymer chain at thermodynamic equilibrium with a heat bath. We concentrate on th ...

Cold denaturation of yeast frataxin offers the clue to understand the effect of alcohols on protein stability

Paolo De Los Rios

Although alcohols are well-known to be protein denaturants when present at high concentrations, their effect on proteins at low concentrations is much less well characterized. In this paper, we present a study of the effects of alcohols on protein stabilit ...

Domain switching contribution to piezoelectric response in BaTiO3 single crystals

Li Jin, Zhuo Xu

Piezoelectric responses of barium titanate single crystals are investigated along the [720] and [111] directions, respectively, in order to verify the ultrahigh piezoelectric constant (2000 pC/N) reported in a previous study [Appl. Phys. Lett. 86, 012905 ( ...

Reactivity of electrogenerated free hydroxyl radicals and activation of dioxygen on boron-doped diamond electrodes

Agnieszka Kapalka

Synthetic boron-doped diamond (BDD) thin film is an electrode material with high chemical and dimensional stability, low background current and a very wide potential window of water stability. Upon anodic polarization, BDD generates hydroxyl radicals that ...

Evaporation from three water bodies of diﬀerent sizes and climates: Measurements and scaling analysis

Shirit Cohen, Marc Parlange, Gabriel George Katul, Scott W. Tyler

Evaporation from small reservoirs, wetlands, and lakes continues to be a theoretical and practical problem in surface hydrology and micrometeorology because atmospheric ﬂows above such systems can rarely be approximated as stationary and planar-homogeneous ...

Small scale SOFC systems

Nordahl Autissier

The increasing cost of carbon based fuels pushes the electricity generation market towards more efficient electricity generation technologies. In this context, fuel cells offer the opportunity to increase efficiency and lower CO2 and NOx emissions, in part ...

Seismic design of torsionally eccentric buildings with U-shaped RC walls

Katrin Beyer, Alessandro Dazio

The objective of the present work is that of making a contribution to the performance-based seismic design of RC buildings with U-shaped walls. Since U-shaped walls are often placed at the perimeter of a building and are typically stiffer and stronger than ...

Quo vadis thermodynamics and the city: a critical review of applications of thermodynamic methods to urban systems

Jean-Louis Scartezzini, Darren Robinson, Nataliya Filchakova

Cities are complex dynamic entities. From a thermodynamic perspective, they represent open systems, constantly importing and exporting energy and matter across their boundaries; the output invariably being less ordered due to irreversible internal processe ...
