Ukraine strikes Ilsky Oil Refinery in Russia’s Krasnodar Krai

#Ukrainian #drones hit #Ilsky #Oil #Refinery in #Krasnodar Krai & #Kropotkinskaya oil #pumping station in #Kavkazsky District of #Kuban overnight on Feb. 17

“The SBU and SSO of the Armed Forces continued the introduction of ’drone sanctions’ against two important #Russian enterprises that work for the enemy #military-industrial complex,” the source said.

Flushing the Brain During Sleep

When we sleep, our brains flush out waste that builds up during our waking hours, but how this happens has been something of a mystery. A new study of sleeping mice has visualized and tracked the flow for the first time. The researchers found that, during a specific sleep phase (the non-rapid eye movement portion), the mice released pulses of norepinephrine — a cousin to adrenaline — that periodically contracted blood vessels in the rodents’ brains. As these blood vessels contract and relax, it forces the nearby cerebrospinal fluid to flow. In short, the pulsing of the blood vessels pumps the fluid bathing the brain, flushing it.

The team also found that certain medications — like the sleep aid Ambien — disrupted this flow in mice by suppressing the blood vessels’ oscillations. It’s not known yet whether our brains operate on the same pumping principle or whether medications could affect that, but it does suggest that a similar study in humans is worthwhile.

After #pumping the #DJT #stock since 23.Sep. from 12 US$ to 34 US$ yesterday the stock fell today by 9 US$ to 25 US$ which is in fact a huge #crash in this short time. I'm curious to see how it continues. Actually this company is already broke because it makes no profit and has much more expenses than income.

If this company discontinues its business for any reason every share will be worthless in no time.

"KEY POINTS
• Surface ice-melt water can migrate downward driven by the osmotic pressure associated with a cryopeg, a lens of salty water below
• Overpressure can cause the frozen soil to crack resulting in mechanical explosion.."

schematics - Warming causes melting in the active layer, which expands deeper into the permafrost. Meltwater then enters the salty cryopeg through osmosis, causing the expansion of the cryopeg, which cracks the overlying permafrost. When those cracks reach the surface, the rapid decrease in pressure in the cryopeg damages the methane hydrates below and triggers a rapid physical explosion. Images not to scale.
