in this paper, we used tetranuclear copper (ii) schiff base complexes, [cu4 (μ-sal2hn) (μ-n3)2(n3)2] (1) and [cu4 (μ-salophen) (μ1, 1-n3)2(n3)2] (2), as new precursor in solid-state thermal decomposition for the synthesis of cuo nanoparticles. the crystallinity, purity and morphology of the cuo nanoparticles were characterized by fourier transform infrared (ft-ir), x-ray diffraction (xrd) and s...

Energy-momentum tensor of Liénard-Wiechert field is split into bound and emitted parts in Rindler frame, by generalizing the reasoning of Teitelboim used in inertial frame. Our discussion proceeds with the the notion of “energy” defined with respect to the Killing vector field attached to the frame. We obtain the “radiation formula in Rindler frame”(Rindler version of Larmor formula) and it is ...

Large scale traffic congestion often stems from local traffic jam in single road or intersection. In this paper, macroscopic method was used to explore the formation and propagation of local traffic jam. It is found that (1) the propagation of traffic jam can be seen as the propagation of traffic signal parameters, that is, virtual split and virtual green time; (2) for a road with endogenous fl...

Suppose that λ = μ and μ is singular. We consider two aspects of the square property on subsets of λ. First, we have results which show e.g. that for א0 < κ = cf(κ) < μ, the equality cf([μ],⊆) = μ is a sufficient condition for the set of elements of λ whose cofinality is ≤ κ, to be split into the union of μ sets with squares. Secondly, we introduce a certain weak version of the square property ...

Suppose that λ = μ+ and μ is singular. We consider two aspects of the square property on subsets of λ. First, we have results which show e.g. that for א0 < κ = cf(κ) < μ, the equality cf([μ]≤κ,⊆) = μ is a sufficient condition for the set of elements of λ whose cofinality is ≤ κ to be split into the union of μ sets with squares. Secondly, we introduce a certain weak version of the square propert...

Searching for achieving an ambitious reduction in greenhouse gas emissions, the EU has set as a goal modal shift freight transport of 30% by rail near future. In this context, it is vital to use choice models road versus assess shippers’ acceptance actions promoting rail. This paper develops combined model jointly evaluating split and railway flows, addressed case when based on random utility a...
