Tires are an example of products subject to extended producer responsibility in many industrialized countries. Extended producer responsibility (EPR) is a strategy to add all of the estimated environmental costs associated with a product throughout the product life cycle to the market price of that product, contemporarily mainly applied in the field of waste management.

Electron paramagnetic resonance (EPR) or electron spin resonance (ESR) spectroscopy is a method for studying materials that have unpaired electrons. The basic concepts of EPR are analogous to those of nuclear magnetic resonance (NMR), but the spins excited are those of the electrons instead of the atomic nuclei. EPR spectroscopy is particularly ...
In broad EPR spectra where Δω > ω 1 it is not possible to tip all the magnetization into the xy-plane to generate a strong FID signal. This is why it is important to maximize ω 1 or minimize the π/2 pulse length for broad EPR signals. So far the magnetization was tipped into the xy-plane and it remained there with the same magnitude.

The Bell measurement is an important concept in quantum information science: It is a joint quantum-mechanical measurement of two qubits that determines which of the four Bell states the two qubits are in. Quantum circuit that performs Bell decoding. Bell states are sometimes called EPR pairs.
The EI-EPR spectra can be collected in two ways: (1) difference spectra [7] (2) frequency modulated rf field without Zeeman modulation. This technique was established by Hyde [7] and is especially useful for separating overlapping EPR signals which result from different radicals, molecular conformations or magnetic sites. EI-EPR spectra monitor ...

But EPR had to cut its dividend during the pandemic. The big culprit was its movie theater exposure, as movie chains weren't in a particularly strong state entering the global health crisis. Given ...
