Fundamental equation of state for mixtures of nitrogen, oxygen, and argon based on molecular simulation data.

A fundamental equation of state in terms of the Helmholtz energy is presented for mixtures of nitrogen, oxygen, and argon at any composition. It is expressed in terms of the residual Helmholtz energy and can be used to calculate all thermodynamic equilibrium properties including vapor-liquid equilibria. The parameters of the equations for the pure-fluid and mixture contributions are fitted exclusively to molecular simulation data so that the model has a predictive character.

Equation of state for the Mie (λ,6) fluid with a repulsive exponent from 11 to 13.

An empirical multi-parameter equation of state in terms of the reduced Helmholtz energy is presented for the Mie (λ-6) fluid with a repulsive exponent λ from 11 to 13. The equation is fitted to an extensive dataset from molecular dynamics simulation as well as the second and third thermal virial coefficients. It is comprehensively compared with the SAFT-VR model and is a more accurate description of the considered fluid class.

Data on the thermochemical potential of six Cuban biomasses as bioenergy sources.

Data on the rapid, elemental and calorimetric analysis, such as ash melting behaviour and thermogravimetric profiles of six Cuban biomass feedstock are shown, in order to assess their potential for bioenergy production. The studied biomasses are husk, husk, , , and . Seed, kernels or stems and algae were characterized by weight.

Role of the plasmid-encoded tet(O) gene in tetracycline-resistant clinical isolates of Campylobacter jejuni and Campylobacter coli.

The prevalence of tetracycline resistance, tetracycline MICs and tet(O) gene localization were investigated in 83 Campylobacter isolates from patients suffering from acute gastroenteritis in Germany. Combined biochemical and molecular markers identified 74 isolates (89 %) as Campylobacter jejuni, including seven atypical isolates that failed to hydrolyse hippurate, and nine isolates (11 %) as Campylobacter coli. Tetracycline resistance was detected in six out of nine Campylobacter coli isolates (67 %) and 13 out of 74 C.

Identification and characterization of a major subgroup of conjugative Campylobacter jejuni plasmids.

Objectives: Enterocyte invasion of Campylobacter jejuni 81-176 has been reported to depend upon the virulence plasmid pVir. The objective of this study was to determine the prevalence of pVir in clinical C. jejuni isolates, to investigate DNA homologies between C.
