Die #EU ist eine großartige Idee und wir sollten sie erhalten, gerade unter Druck von außen.

Einige Dinge gehen mir aber zu weit: zu viel Bürokratie, zu viel Regulierung - das gilt im Übrigen nicht nur für die #EU, sondern auch für #Deutschland.

Erhalten und besser machen!

My son is having a public health strategy for his packed lunch today.

Congratulations! Well deserved.

We use teflon tubing for water critical parts before the chiller.

So why did they change it? Is it cheaper?

We sometimes make liqueur or chutney out of them. But yes it was more than I expected.

I just made 45 jars of quince jelly but with a steam juicer. Our tree in the garden had almost 30 kg of quince. We never had so many before.

While roaming in Paris, you can typically use all available networks while at home you can only use one. Therefore it is likely that the coverage provided by all networks is better.

But the worst problem are devices that rely on external servers. Because there is never a guarantee that they will be supported for more than the lifetime of the current management. I avoid them at almost all costs.

I agree, this is a problem but probably not for washing machines/dryers/fridges and stuff like this. They might not get new features but usually this is not a problem. TVs are different since they have to interact with the outside.

Why would you connect a fridge to the WIFI?

"High field" is in the same league as (ultra-)fast MAS.

Why?

When performing spin dynamics simulations under MAS, it is necessary to do 3-angle averaging. Conventionally this is done with 2-angle averaging and a gamma-carousel average. We show that this convention should be avoided in favor of proper integrated 3-angle averaging.

Spezi - Wikipedia

Mezzo Mix is a brand name. The generic name (at least in southern Germany) which is also a trade name to make things complicated is Spezi.

Gibt es da eigentlich genauere Informationen was gemacht wurde und was passiert ist, dass die Bauarbeiten nicht abgeschlossen werden konnten?

Bumps on the Road: The Way to Clean Relaxation Dispersion Magic-Angle Spinning NMR Microsecond-to-millisecond motions are instrumental for many biomolecular functions, including enzymatic activity and ligand binding. Bloch-McConnell Relaxation Dispersion (BMRD) Nuclear Magnetic Resonance (NMR) spectroscopy is a key technique for studying these dynamic processes. While BMRD experiments are routinely used to probe protein motions in solution, the experiment is more demanding in the solid state, where dipolar couplings complicate the spin dynamics. It is believed that high deuteration levels are required and sufficient to obtain accurate and quantitative data. Here we show that even under fast magic-angle spinning and high levels of deuteration artifactual “bumps” in 15N R1ρ BMRD profiles are common. The origin of these artifacts is identified as a second-order three-spin Mixed Rotational and Rotary Resonance (MIRROR) recoupling condition. These artifacts are found to be a significant confounding factor for the accurate quantification of microsecond protein dynamics using BMRD in the solid state. We show that the application of low-power continuous wave (CW) decoupling simultaneously with the 15N spin-lock leads to the suppression of these conditions and enables quantitative measurements of microsecond exchange in the solid state. Remarkably, the application of decoupling allows the measurement of accurate BMRD even in fully protonated proteins at 100 kHz MAS, thus extending the scope of μs dynamics measurements in MAS NMR.

Our latest publication in @jacs.acspublications.org is out: pubs.acs.org/doi/10.1021/...
We show clean ways to probe dynamics on microsecond time scales by relaxation-dispersion MAS #NMR. Microsecond motions are often essential for function e.g. in enzymes.

An example is when you do polarization transfer and only one of the exchanging species is generated for whatever reason.

If the initial state at the start of the experiment is not the equilibrium state and the system evolves towards the equilibrium. I am not sure what your experiment was.
