Patients And Methods: Materials and Methods: Retrospective cohort study was conducted from January 2018 to December 2022 in four tertiary care hospitals of Ukraine. The diagnostic criteria were based on specific HAI site were adapted from the CDC/NHSN case definitions.
We utilized a metal propionate solution to prepare polycrystalline bismuth-substituted yttrium iron garnets through the metal-organic decomposition process. After conducting thorough optimization, we successfully synthesized a garnet that exhibited a high magneto-optic response directly at the end of an optical fiber. A notable achievement of our work lies in the ability to restrict the size and position of the garnet to match the dimensions of the fiber's core.

- Understanding how parton mass and Casimir color factors affect heavy quark emissions is key to studying quantum chromodynamics (QCD).
- This research presents the first experimental constraint on the charm-quark splitting function, obtained through measurements in proton-proton collisions at 13 TeV.
- Findings indicate that charm quarks show a steeper splitting function compared to gluons and light quarks, experiencing fewer emissions with a lower likelihood of large-angle emissions.
Objective: The aim: To study the hemodynamic parameters in patients with post-stroke pain syndromes.
Patients And Methods: Materials and methods: We examined the hemodynamic parametrs of 74 patients who were treated at the Departments of General Neurology, Vascular Neurology and Pain Center in the Clinical Hospital «Feofania» State Administrative Department. Main group (44 patients) had stroke in anamnesis and chronic pain (headache, back pain, joint pain).
