“We are a nation of laws.
You can't just make up things whole piece,”
said Senator Bill Cassidy,
following his primary loss.
“People are concerned about making ends meet, not about putting a slush fund together without a legal precedent.”
It’s not clear yet what approach Cassidy will take in his final months in office,
but he’s got plenty of opportunities to make his voice heard,
including on the effort to limit U.S. hostilities against Iran wi…

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.

A few highlights from the Turkish-Persian section of a random carpet symbolism book I skimmed while stopped at a random library in New Jersey a couple days ago

Tree of life: one of the oldest and most universal symbols of mankind.

It supports the sky, and provides a path from earth to heaven. In different cultures it is called by names such as haoma, asherak, yggdrasil, irminsu or asvattha.

Thus, one often sees it in prayer rugs, as a reminder of the passage from this existence into a higher life.
Diamond or Lozenge:

It has been conjectured that this omnipresent motif in Anatolian kilims is a male triangle attached to a female triangle, and thus signifies creation. There are doubtless many interpretations. A diamond surrounded by hooks is called in Turkish kirkbudatz, 'forty branches'.

Among some semi-nomadic pastoral (terekme) tribes of Azerbaijan, a favourite symbol is a large diamond, signifying woman. Smaller diamonds within the large one signify a pregnant woman or her progeny. A …
Celestial creature: Recognizable because flames appear from flanks or shoulders.
Arabesque or Tendril:

The basic unit of the arabesque, a favourite Islamic decorative theme, may be described as a split leaf seen in profile, called islimi in Persian. Derived from a Sassanian motif, it developed under the Abbasids in the ninth and tenth centuries, and matured under the Seljuks in the twelfth and thirteenth. It became central in Turkish and Persian carpet design only after the fifteenth century. In its fascinating fully developed form one sees interlaced lattice systems of sp…

Also worth noting that cellular/mobile phones still provided an actual working service.
Yes there were trade-offs, but the core functions that people wanted were there.

The Newsom administration is suing five more California cities
— Calexico, Costa Mesa, Half Moon Bay, Ridgecrest and Turlock — for failing to complete state-mandated housing plans, known as the “housing element.”

Huntington Beach was the first city to face such a legal action, and it recently finalized its housing element plans following a court-order and massive fines.
The law, which has been in place since 1969, requires cities and counties every eight years to d…

I may be able to get a similar engine for the mower for €100-150 if the guy at the mower shop can actually get it off the machine it is currently on in an amount of time congruent with its value. Failing that, we're looking at €800-1200 for a new unit to fix a mower I paid €1400 for. Brutal.
Ireland is a small, isolated market. You really feel it when trying to get anything that isn't the most bog-standard commodity product.

Even naar de glasbak gefietst, met de #trike, mijn oude Koga staat ongebruikt in de schuur, om glas te recycleren. Daarna naar een in een Albert Hein verstopte geldmaat om mijn nieuwe bankpas van een gewenste pincode te voorzien. En toen maar even over de fietssnelweg naar fietsknoop 6 en dan weer naar huis. Ik had er flink de pas in, of hoe heet dat bij fietsen. 20,3 kilometer

het begin van de fietssnelweg
knoop 6, tevens keerpunt.
