Coracoid Process Fracture Associated With a Distal Clavicle Fracture: A Case Report

Background. Fracture of the distal clavicle fracture associated with a coracoid process fracture is extremely rare in the practice of an orthopedic surgeon. Therefore, there is no common approach to the treatment of patients with this type of bone injuries of the shoulder girdle. Aim of the study to demonstrate positive experience of conservative treatment of the coracoid process fracture combined with hook plate fixation for distal clavicle fracture. Case presentation. We present a rare clinical case of a closed distal clavicle fracture associated with coracoid process fracture. Trauma occurred when the patient fell down the stairs on his abducted upper limb. After examination, the distal clavicle fracture was fixed with a hook plate. Intraoperatively, X-rays showed a satisfactory position of the coracoid process of the scapula. Therefore, it was decided not to fix it additionally. CT scans three months after the surgery showed bone fragments consolidation. Removal of the hook plate and screws from the clavicle was performed. Conclusion. Presented clinical case illustrates successful treatment result of this type of fractures without fixation of the coracoid process fracture. The hook plating allows to stabilize bone fragments and restore ligament tension, which makes this implant non-alternative for fixation of this type of injuries

Светская христианская двуименность в эпитафиях Московской Руси (вокруг трех неопубликованных надписей XVI–XVII вв.)

The article analyses the little-explored cultural practice of dual Christian naming as reflected on 16th and 17th century gravestones. The study focuses on key linguistic aspects of representing several names of the deceased; the principles of name-giving and dual name functioning – both during a person's life and after their passing—are reconstructed with special attention to epitaphic texts. By adopting an onomastic approach, the authors are able to attribute several gravestones; a number of inscriptions, previously unstudied, are researched for the first time. DOI: 10.31168/2305-6754.2022.11.2.14Настоящая работа посвящена малоизученному феномену запечатления светской христианской двуименности на надгробных плитах XVI–XVII вв. В исследовании анализируются основные лингвистические параметры репрезентации нескольких имен усопшего и воссоздаются те принципы имянаречения и функционирования разных имен одного и того же человека при его жизни и после кончины, которые можно проследить, опираясь на эпитафии. Благодаря ономастическому ракурсу авторам удалось атрибутировать несколько надгробных плит, в научный оборот вводятся ряд ранее не публиковавшихся надписей. DOI: 10.31168/2305-6754.2022.11.2.1

Challenges in QCD matter physics - The Compressed Baryonic Matter experiment at FAIR

Substantial experimental and theoretical efforts worldwide are devoted to explore the phase diagram of strongly interacting matter. At LHC and top RHIC energies, QCD matter is studied at very high temperatures and nearly vanishing net-baryon densities. There is evidence that a Quark-Gluon-Plasma (QGP) was created at experiments at RHIC and LHC. The transition from the QGP back to the hadron gas is found to be a smooth cross over. For larger net-baryon densities and lower temperatures, it is expected that the QCD phase diagram exhibits a rich structure, such as a first-order phase transition between hadronic and partonic matter which terminates in a critical point, or exotic phases like quarkyonic matter. The discovery of these landmarks would be a breakthrough in our understanding of the strong interaction and is therefore in the focus of various high-energy heavy-ion research programs. The Compressed Baryonic Matter (CBM) experiment at FAIR will play a unique role in the exploration of the QCD phase diagram in the region of high net-baryon densities, because it is designed to run at unprecedented interaction rates. High-rate operation is the key prerequisite for high-precision measurements of multi-differential observables and of rare diagnostic probes which are sensitive to the dense phase of the nuclear fireball. The goal of the CBM experiment at SIS100 (sqrt(s_NN) = 2.7 - 4.9 GeV) is to discover fundamental properties of QCD matter: the phase structure at large baryon-chemical potentials (mu_B > 500 MeV), effects of chiral symmetry, and the equation-of-state at high density as it is expected to occur in the core of neutron stars. In this article, we review the motivation for and the physics programme of CBM, including activities before the start of data taking in 2022, in the context of the worldwide efforts to explore high-density QCD matter.Comment: 15 pages, 11 figures.

New ceramic materials from MSWI bottom ash obtained by an innovative microwave-assisted sintering process

Preliminary results on the production of new ceramic bricks by an innovative microwave-assisted sintering process employing MSWI bottom ashes are reported. Microwave heating technique was compared with a conventional thermal treatment with the aims to: (1) study the influence of heat treatment method on the crystallization behavior and on the microstructure of obtained samples; (2) define the crystallization evolution in microwave field; (3) gain an insight into the physical properties of the new samples. Higher crystallinity and new crystal phases were observed in the samples prepared by microwave heating, where precipitation of new sodium rich crystal phases was observed, together with quartz and anorthite, formed in the conventionally prepared samples. The possibility to obtain novel bricks with huge waste amount, in a very short thermal cycle and at relatively low temperatures was demonstrated with significant reductions in the energy demand for their production. Finally, the samples obtained by microwave-assisted sintering are characterized by improved mechanical properties

Synthesis and characterisation of new tripodal lanthanide complexes and the investigation of their optical and magnetic properties

This paper presents the synthesis of a tripodal ligand (H3L) via the Schiff base condensation of N,N-diethylsalicylaldehyde and tris(2-aminoethyl)amine. The neutral complexes of type [EuL], [GdL] and [DyL] were synthesized and characterized by FT-IR, SEM-EDS, PXRD, single crystal X-ray diffraction, CHN analysis and high resolution ESI-MS. X-ray crystallographic studies demonstrated that the heptadentate ligand incorporating a cavity pre-organized by hydrogen bonding binds the Ln(iii) ions to yield a face capped octahedral coordination geometry with three-fold symmetry. Photoluminescence studies show a typical Ln(iii) absorption character for the three complexes, with [EuL] demonstrating considerably stronger lanthanide-based luminescence peaks, and a Eu(iii) centered luminescence lifetime of 0.144 + 0.01 ms. Temperature/field-dependent DC and temperature/frequency-dependent AC magnetic measurements carried out for the Dy(iii) complex indicated obvious magnetic anisotropy and suggested slow relaxation behaviour with considerable quantum tunnelling of the magnetization contribution
