Abstract: We present a comprehensive framework for gravity-driven, surfactant-laden thin films flowing over slippery substrates, elucidating how wall slip modifies the coupled hydrodynamics and interfacial transport. A long-wave model is formulated with a conservative bulk-surface mass balance and a Navier slip condition. The Orr-Sommerfeld eigenvalue problem governs the linear regime, while a weighted-residual model captures the nonlinear evolution over a range of equilibrium surfactant coverages, Marangoni strengths, and adsorption kinetics. The analysis predicts a non-monotonic variation of the critical Reynolds number with equilibrium coverage, exhibiting a maximum at intermediate $\Gamma_e$, and a slip-induced transition from single- to double-hump solitary structures with increasing Marangoni number, accompanied by attenuated capillary ripples. Under fast adsorption kinetics, the surface field homogenizes, preserving the mean film shape and flux while flattening both the surface concentration $\Gamma$ and the bulk inventory $\chi h\phi$. A spurious interfacial mass growth reported by Pascal et al.(PRF, 2019) and D'Alessio et al.(JFM, 2020) is resolved through a revised surface balance ensuring strict conservation. Wall slip thus emerges as a key control parameter, reducing viscous resistance and mitigating Marangoni back-stress. The slip parameter $\beta$ is a useful control knob for surfactant-laden films. Slip prevents fragile multi-hump bound states, promoting a single broad crest or an almost flat, uniform sheet by carefully bonding $\beta$ to wave selection, ripple damping, and the bulk-surface surfactant balance.

Ok. I have to accept that I have a problem. Despite a massive cull a few months ago, my current Firefox tab count, across 4 windows, has crept up to 2020. This madness has to stop. Problem is that for each one I want to close, I have to load it and look at it to make sure I can handle letting it go. I may be some time. Wonder where this activity would fall with regard to our national 'GDP'.

Ce qui est intéressant dans la décision, c'est que la justice française s'aligne sur une classification faite par la justice allemande il y a 6ans (BGH Urt. v. 18.06.2020, Az. 4 StR 482/19). Le cas allemand était encore moins claire, car la volonté n'avait pas été relevé avec la même clarté. Selon le BGH, il suffisait que l'automobiliste était indifférent au sort des autres.
May 2026 was the second-warmest May on record globally, in between 2024 and 2025.
The global average temperature was 15.81°C, 0.55°C above the 1991-2020 average for May and 1.42°C above the estimated 1850-1900 pre-industrial average for the month.

What Kent wears, the glasses, the business suit... that's the costume that Superman wears to blend in with us. Clark Kent is how Superman views us. And what are the characteristics of Clark Kent? He's weak, he's unsure of himself, he's a coward. Clark Kent is Superman's critique on the whole human race.

Both solar and wind power now produce more of the world's electricity than nuclear.
More importantly, they're the growth engines, ready to finally make a dent in the amounts of coal and gas used for electricity. And in the emissions arising from that!
