DOWN at the bottom of the specifications sheet for the Porsche Panamera Turbo, past the eyebrow-raising power rating of the 4.8-liter V-8 and beyond the head-spinning acceleration figures (and 188-mile-per-hour top speed), lies a pleasant surprise: this supersedan, with an E.P.A. rating of 15 m.p.g. in town and 23 on the highway, incurs no federal guzzler tax.
To keep the juice flowing to the road, the SSR will also get a performance TORSEN differential that transfers power away from either rear wheel if it spins under acceleration.
On the contrary, in W-directed subduction zones, where volcanism develops in back-arc extensional regime, Earth's spin accelerations (LOD decrease) produce larger differential stresses by enhancing the σ 3 tensor (Fig. 4).
Conversely, an opposite trend is observed in the year after significant Earth's spin accelerations with ΔLODeff, below the 25th percentile, when r E/W = 0.46 decreases by ~28%%.
Klein points to a salient fact about natural accelerators: a small, rapidly spinning object must accelerate particles very rapidly; this requires an extremely energy-dense environment, and there are many ways the particles could lose energy during the acceleration process.
Non-linear dynamic responses are analyzed for a flexible spinning disc with angular acceleration.
Neutrophil adherence was achieved by plating a suspension of sorted neutrophils in seahorse assay media with 2 mM glutamine and 25 mM Glucose and spinning at the lowest acceleration to 45×g followed by natural deceleration.
Purified neutrophils were plated in 96-well U-bottomed plates at 0.125 × 106 cells per well in RPMI supplemented with (Pen/Strep, 10% FCS, 2 mM L-glutamine, 1 M HEPES, 0.1 mM nonessential amino acids) and adhered by spinning at the lowest acceleration to 45×g followed by natural deceleration.
PαMS was spin-cast from toluene solution with 3 and 10 mg mL−1 concentration to give 6 and 10 nm thick films, respectively; spin speed and acceleration were 4000 rpm and 10,000 rpm min−1 in both cases.
During the process of writing and editing (with Jay Cornell) a book about these types of advances, I got to experienced the head spinning vertiginous nature of technological and scientific acceleration.
Traction control, which maximises acceleration by preventing the rear wheels spinning, has been banned from F1 since 2009.
