National parks are deteriorating. There’s a fix Congress isn’t making.
The national park system faces a maintenance backlog of $24 billion in crumbling roads, aging water systems, washed-out trails and dilapidated visitor facilities.
That is more than seven times the National Park Service’s annual budget.
Last month, committees in both the House and Senate advanced bipartisan bills to dedicate roughly $1.3 billion annually for park maintenance over the next five years. …

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.

Van Dijk's declining speed means the backline discipline is not consistent. The shape is skewed because he sags to prevent being exposed by speedier players and it instead allows space in behind on the flanks.
Chiesa thought he had played it correctly and was stunned to find Digne onside.

Andi Tepelena, a prominent activist and art curator organizing the 2026 civic protests in Tirana, Albania
made these remarks to emphasize the deepening political crisis.
He stated that m
"the regime has activated an army of patronage Nazis to tarnish the protest,"
but added that this battle has been won by the citizens and their supporters.
Tepelena stressed that protesters are united around the demand for the removal of the government and a profound c…
