The application of electron paramagnetic resonance (EPR) spectroscopy in pharmacy of melanin complexes with netilmicin and Cu(II) was presented. The continuous microwave saturation of EPR spectra of DOPA-melanin and the complexes was performed. EPR spectra were measured on an X-band (9.3 GHz) spectrometer at temperatures in the range of 105-300 K. Paramagnetic copper ions decrease the intensity...

Electron paramagnetic resonance (EPR) spectroscopy has been successfully employed to determine radiation dose using alanine. The EPR signal intensity reflects the number of stable free radicals produced, and provides a quantitative measurement of the absorbed dose. The aim of the present study was to explore whether this principle can be extended to provide information on spatial dose distribut...

The enhanced principal rank characteristic sequence (epr-sequence) of an n×n matrix is a sequence `1`2 · · ·`n, where each `k is A, S, or N according as all, some, or none of its principal minors of order k are nonzero. There has been substantial work on epr-sequences of symmetric matrices (especially real symmetric matrices) and real skew-symmetric matrices, and incidental remarks have been ma...

Health care organisations are extremely complex because they consist of heterogeneous groups of people (clinical professions, patients, managers), use advanced technology (medical devices and patient record systems), and apply many organisational and clinical routines. When introducing Electronic Patient Record systems (EPR) in health care organisations, all these aspects get affected. Using a ...

The paper investigates, in the framework of branching space-times, whether an infinite EPR-like correlation which does not involve finite EPR-like correlations is possible.

The enhanced postoperative recovery (EPR) program is designed to reduce organ dysfunction after surgery, which improves morbidity and speeds recovery by attenuating surgical stress or pain. The main focus of the program is to reduce the use of nasogastric tubes, drains, urinary catheters, and preoperative bowel preparations as compared to conventional recovery procedures and to initiate oral fe...

BACKGROUND In heart failure, the cardiovascular response to activation of the skeletal muscle exercise pressor reflex (EPR) is exaggerated. Group IV afferent neurons, primarily stimulated by the metabolic by-products of skeletal muscle work, contribute significantly to the EPR. Therefore, it was postulated that alterations in the activity of group IV neurons contribute to the EPR dysfunction ma...

Optical and magnetic properties of SiO2:C nanopowders obtained by chemical and thermal modification of fumed silica were studied by Fourier transform infrared spectroscopy, Raman, continuous wave (CW) electron paramagnetic resonance (EPR), echo-detected EPR and pulsed electron nuclear double resonance (ENDOR) spectroscopy. Two overlapping signals of Lorentzian lineshape were detected in CW EPR ...

A bstract The ER = EPR correspondence relates a superposition of entangled, disconnected spacetimes to connected spacetime with an Einstein-Rosen bridge. We construct examples in which both sides may be described by weakly-coupled string theory. relation between them is given Lorentzian continuation the FZZ duality two-dimensional Euclidean black hole CFT one example, and another example simila...
