A Spectroscopic Study of Field and Runaway OB Stars
Identifying binaries among runaway O- and B-type stars offers valuable
insight into the evolution of open clusters and close binary stars. Here we
present a spectroscopic investigation of 12 known or suspected binaries among
field and runaway OB stars. We find new orbital solutions for five single-lined
spectroscopic binaries (HD 1976, HD 14633, HD 15137, HD 37737, and HD 52533),
and we classify two stars thought to be binaries (HD 30614 and HD 188001) as
single stars. In addition, we reinvestigate their runaway status using our new
radial velocity data with the UCAC2 proper motion catalogs. Seven stars in our
study appear to have been ejected from their birthplaces, and at least three of
these runaways are spectroscopic binaries and are of great interest for future
study.Comment: 21 pages, 1 figure, 7 tables; Accepted to Ap

Modeling of segmental excavator working tool for soil compaction
The development of a methodology for physical modeling of the working process and a replaceable working tool of an excavator for soil compaction in the construction, maintenance, and repair of man-made engineering structures in confined spaces are considered in the article. This methodology is based on a rheological model of the soil compaction process containing Hooke and Newton's elements connected in parallel (the Voigt model is the method of integral analogs that have been used to obtain the main similarity criteria that adequately characterize the process of static compaction during elastoviscoplastic soil deformation). The formulas for the transition from the model parameters to the parameters of the full-scale process of soil compaction by a segmental working tool are obtained based on similarity criteria for modeling the option without changing soil properties
Stability of the inverse resonance problem on the line
In the absence of a half-bound state, a compactly supported potential of a
Schr\"odinger operator on the line is determined up to a translation by the
zeros and poles of the meropmorphically continued left (or right) reflection
coefficient. The poles are the eigenvalues and resonances, while the zeros also
are physically relevant. We prove that all compactly supported potentials
(without half-bound states) that have reflection coefficients whose zeros and
poles are \eps-close in some disk centered at the origin are also close (in a
suitable sense). In addition, we prove stability of small perturbations of the
zero potential (which has a half-bound state) from only the eigenvalues and
resonances of the perturbation.Comment: 21 page

Objective. Radical nephrectomy with thrombectomy of the inferior vena cava is the preferred treatment for renal cell carcinoma with an tumor thrombosis. We describe our experience and presentreview of the literature evaluating the feasibility and safety of laparoscopic nephrectomy with inferior vena cava thrombectomy.Materials and methods. The study included 37 patients who underwent laparoscopic radical nephrectomy with level IβIII thrombectomy for renal cell carcinoma in our institution from 2018 to 2021. We analyzed the clinical, radiographic, intraoperative, pathological and postoperative parameters of the patients. The literature was reviewed by the Medline search engine, PubMed, with a review of publications on laparoscopic radical nephrectomy with inferior vena cava levelIβIIIthrombectomy.Results. The mean operation time was 275 Β± 60.1 min, the median blood loss was 450 Β± 81.6 ml (β₯50 % of the circulating blood volume β 32.4 %). Intraoperative complications were observed during 10 (27.0 %) operations. Postoperative complications developed in 29.7 % of patients and reached gradesIIIβIV according to the ClavienβDindo scale on 13.0 % ill. All patients are activated according to the fast track rehabilitation program. The average hospital stay was 5 days. A literature review identified clinical cases and small series demonstrating the technical feasibility and safety of laparoscopic radical nephrectomy with thrombectomy in selected patients.Conclusion. Laparoscopic radical nephrectomy with thrombectomy is a technically feasible approach in carefully selected patients with level IβIII tumor thrombosis. Optimal patient selection, extensive experience in laparoscopy and specialized centers are essential for the safe use of thistechnique.Π¦Π΅Π»Ρ ΠΈΡΡΠ»Π΅Π΄ΠΎΠ²Π°Π½ΠΈΡ β ΠΏΡΠ΅Π΄ΡΡΠ°Π²ΠΈΡΡ Π½Π΅ΠΏΠΎΡΡΠ΅Π΄ΡΡΠ²Π΅Π½Π½ΡΠ΅ ΡΠ΅Π·ΡΠ»ΡΡΠ°ΡΡ Π²ΡΠΏΠΎΠ»Π½Π΅Π½ΠΈΡ Π»Π°ΠΏΠ°ΡΠΎΡΠΊΠΎΠΏΠΈΡΠ΅ΡΠΊΠΎΠΉ ΡΠ°Π΄ΠΈΠΊΠ°Π»ΡΠ½ΠΎΠΉ Π½Π΅ΡΡΡΠΊΡΠΎΠΌΠΈΠΈ Ρ ΡΡΠΎΠΌΠ±ΡΠΊΡΠΎΠΌΠΈΠ΅ΠΉ ΠΈΠ· Π½ΠΈΠΆΠ½Π΅ΠΉ ΠΏΠΎΠ»ΠΎΠΉ Π²Π΅Π½Ρ IβIII ΡΡΠΎΠ²Π½Π΅ΠΉ Π² ΡΡΠ»ΠΎΠ²ΠΈΡΡ

HPV-Genotype Distribution and Oncogene Expression in HIV-Positive Adults and the Underlying Risk Factors for Anal, Oral and Genital Malignancy: An Atlantic Canada Prospective Cohort Study
THE ANALYSIS OF RESULTS OF TREATMENT A SHOULDER PRIMARY TRAUMATIC DISLOCATION
The analysis of results of treatment a primary traumatic dislocation of a shoulder in 36 patients is carried out. The significant amount of adverse results was revealed that testifies to necessity of change of a technique of treatment this pathology, especially in patients of elderly age
To the question of the immobilization after the reduction of primary traumatic shoulder dislocation (review)
The article presented the evolution of views on the conservative treatment of primary traumatic shoulder dislocation. The shortcomings of common method of conservative treatment for shoulder dislocation are listed, as well as the ways to eliminate them. The trends for further investigations for this problem are marked.The authors conclude that the standard treatment for primary traumatic shoulder dislocation is the immobilization of the damaged shoulder joint immediately after atraumatic traction reposition in the position of external rotation for a period of 3 to 7 weeks
