Over the past two decades, river cruise tourism has witnessed a strong development, being preferred by more tourists each year, to the Fan Chain detriment of other forms of tourism.The presence of a plethora of attractive resources, concentrated along the inland waterways represents a particular offer for tourism development, through proper plannin

In the title coordination polymer, [PbBr(C6H5N2O2)(H2O)]n, the PbII atom is coordinated by one pyrazine N atom, two bridging Br atoms, a water molecule ETi 250 Parts and three carboxylate O atoms.Bridging by the two anions generates a layer structure parallel to (001); the layers are linked by Meat Alternative O—H.N and O—H.Br h

Mainly addressed in this paper is the stability problem of continuous-time switched cascade nonlinear systems with time-varying delays.A robust convergence property is proved first: If a nominal switched nonlinear system with delays is asymptotically stable, then trajectories of corresponding perturbed Boxers system asymptotically approach origin p
