TL;DR: In this paper, the saturation properties on the saturation line of ordinary (light) water substances were studied. And the authors developed compact and accurate representative equations for the following properties: vapor pressure, density, enthalpy and entropy of both the saturated liquid and the saturated vapor.
Abstract: Consistent with the latest experimental data and the recent internationally recommended values for the critical parameters, we have developed compact and accurate representative equations for the following properties on the saturation line of ordinary (light) water substance: vapor pressure, density, enthalpy and entropy of both the saturated liquid and the saturated vapor. These equations form the basis of a ‘‘Supplementary Release on Saturation Properties of Ordinary Water Substance’’ issued by the International Association for the Properties of Steam (IAPS).

TL;DR: In this article, the hadronic structure function F2γ(x, Q2) of the photon in the Q2 range from 10 to 100 GeV2 was measured with the PLUTO detector at the e+e- storage ring PETRA.

TL;DR: In this paper, the photon structure function was measured in the reactionee→eeX for Q2 in the range 0.2
Abstract: We present a measurement of the photon structure functionF2γ in the reactionee→eeX forQ2 in the range 0.2

TL;DR: In this article, a Monte Carlo algorithm for the evaluation of functional integrals is introduced, which is not based on the approximation of the functional integral by a finite-dimensional integral.

TL;DR: In this article, the invariant masses of the hadronic system are limited to the range 4.6 and 12.2 GeV/c, respectively, by a Vector Dominance derived model.
Abstract: We present results on jet production in γγ interactions where both photons are quasi-real. The invariant masses of the hadronnic system are limited to the range 4≦W
vis≦12 GeV/c2. The data approach the quark-Parton-Model (QPM) expectation at the highestp
jet
values (≧4 GeV/c). Jet production at lowp
T
(≦1 GeV/c) can be described by a Vector Dominance derived model. The data also have a component with no apparent jet structure in the range, 1.0 ≦P
jet
≦4.0 GeV/c which can be described by phase space or by models of the QCD hard scattering processes cesses
