Roll waves in floods on inclines

The unstable nature of kinematic waves, resulting from outburst floods on steep inclines, is investigated theoretically using the shallow water equations. A numerical experiment is designed in order to efficiently perform a stability analysis. By analysing ...

Nonparallel spatial stability of shallow water flow down an inclined plane of arbitrary slope

Roll waves are known to occur in the frictional flow of a thin layer of water down an inclined solid surface. For a layer of constant depth, the formation of these waves on a solid plane with small slope angle have been explained as a hydrodynamic instabil ...

Time-lag in Derivative Convergence for Fixed Point Iterations

Daniel Kressner

In an earlier study it was proven and experimentally confirmed on a 2D Euler code that fixed point iterations can be differentiated to yield first and second order derivatives of implicit functions that are defined by state equations. It was also asserted ...

Heterosubstituted or functionalized derivatives of 1- and 2-(trifluoromethyl)naphthalenes emanating from aryne adducts

Frédéric Bailly, Fabrice Cottet

More than two dozen new CF3-substituted naphthalene derivs. were prepd. in an expedient way by employing 3- and 4-(trifluoromethyl)benzyne as the key intermediates. 2- And 4-Chlorobenzotrifluoride were treated with butyllithium and the organometallic speci ...

Explaining the physics of tsunamis to undergraduate and non-physics students

Giorgio Margaritondo

After the recent devastating tsunami in southern Asia, I tried to find a simple way to present the physics of this phenomenon to students-in particular, the origin of the dispersion relation and the consequent wave properties. Being unable to locate a suit ...

Scope and limitations of the double [4+3]-cycloadditions of 2-oxyallyl cations to 2,2 '-methylenedifuran and derivatives

Pierre Vogel, Marc-Etienne Schwenter, Kai Torsten Meilert

The reactivity of various 2-oxyallyl cations toward 2,2'-methylenedifuran (1b), 2,2'-(hydroxymethyl)difuran (1c), 2,2'-(trimethylsilylmethylene)difuran (1d), and di(2-furyl)methanone (1e) has been explored. Difuryl derivatives 1c, 1d, and le refused to und ...

Water wave-driven seepage in marine sediments

David Andrew Barry

The action of water waves moving over a porous seabed drives a seepage flux into and out of the marine sediments. The volume of fluid exchange per wave cycle may affect the rate of contaminant transport in the sediments. In this paper, the dynamic response ...

Derivatives of (2R,3R,4S)-2-Aminomethylpyrrolidine-3,4-diol are Selective alpha-Mannosidase Inhibitors

Pierre Vogel, Sandrine Gerber, Inmaculada Robina, Eliazar Rodriguez Garcia, Raynald Demange

A collection of (2R,3R,4S)-3,4-dihydroxypyrrolidin-2-yl derivatives have been tested for their inhibitory activities toward 25 glycosidases. Competitive (K-i=7.4 VM) and selective inhibition of alpha -mannosidase from jack bean has been found for (2R,3R,4S ...
