A new explicit WET model for the turbulent heat fluxes is derived and developed from the transport equation of the scalar passive flux. In order to study the performance of the model itself, all other turbulent quantities are taken from a DNS channel flow data-base and thus the error source has been minimized. This anisotropic eddy diffusivity model can be solved with a two-equation model for the

The purpose of the article is to identify and look into the function of a number of means of legal international cooperation in administrative law. In this discussion on function, the roles and the interplay of the different tools are highlighted as striking a balance between international cooperation, national self-determination and individual rights. Within this theoretical framework, two main t

Some metal ions, such as copper and zinc, are essential nutrients and catalysts in biochemical reactions. Other metal ions, e.g. cadmium and mercury, are highly toxic elements. Heavy metals detection has proven difficult with classical as well as experimental analytical methods. Novel techniques are required for the measurement of bioavailable toxic elements and for detecting small ligands binding

A formula is proposed for the longshore sediment transport in the swash based on the study by Larson et al. on swash-zone transport and foreshore evolution. Hydrodynamics needed to predict the local transport rate were derived from ballistics theory, where both the cases with and without friction were investigated. The formula was validated with data from two experiments carried out in the Large-s

This paper describes a novel tool for eliciting user requirements early in the design process of mobile applications. The "Mobile Oracle", as we have called it, is intended to help developers and designers obtain a better understanding of what the user wants at different points in space and time. It is an extension of a lo-fi version of the well-established Wizard of Oz technique, but it adds an "

The Bremmer series is used to reduce a complex scattering problem to a sequence of simpler single scattering problems. In the Bremmer series, the wave equation is first decomposed into a coupled system of one-way wave equations. The system is then decoupled into a sequence of one-way wave equations with a fixed point iteration. In this paper, a left symbol representation of the decomposition opera

We report laboratory measurements of oscillator strengths for 44 transitions in the Mn T spectrum covering the wavelength range 209-2780 nm. Nine energy level lifetimes have been measured using time resolved laser-induced fluorescence (LIF). The lifetimes have been combined with branching fractions measured by Fourier transform spectroscopy to obtain absolute oscillator strengths. In total, 24 of
