PurposeSubglottic stenosis (SGS) is defined as an obstruction of the subglottic area, potentially extending towards the first tracheal rings. Although endoscopic procedures are frequently preferred as first-line treatment, (partial) cricotracheal resection (PCTR) offers the most durable results. This study aims at reporting and analysing complications and respiratory and vocal outcomes after PCTR.MethodsFor this retrospective cohort analysis, the files of 37 patients with SGS who underwent PCTR in a tertiary referral center were reviewed. Patient- and stenosis-characteristics along with postoperative outcomes and complications were analyzed using descriptive statistics.ResultsThe majority of patients were female (95%), which reflects the high incidence of idiopathic SGS in our patient group (89.2% vs. 2.7% postintubation SGS and 8.1% SGS related to systemic inflammatory disease). Most patients presented with a Cotton grade II (35.1%) and III (54.1%) stenosis, with a mean craniocaudal stenosis length of 17.5 mm. The vast majority of patients (89.2%) had undergone previous endoscopic procedures. The most common complication after PCTR was fibrin deposit/granulation tissue formation at the anastomotic site (n = 15, 40.5%). Other complications were rare, with anastomotic dehiscence, postoperative haemorrhage and vocal cord paralysis each in 1 patient (2.7%), temporary tracheostomy in 2 patients (5.4%), and postoperative wound infection in 3 patients (8.1%). During follow-up, only 2 patients (5.4%) developed restenosis which was successfully salvaged by endoscopic procedures. No patients were long-term tracheostomy dependent. Post-operative mean peak expiratory flow (PEF) percentage showed a 43.7% increase compared to pre-operative. For the mean increase in maximum inspiratory flow (MIF) at 50% this was 1.3 L/s. VHI (voice handicap index) scores increased significantly from baseline preoperative score of 27.5 (±23.7) to a mean value of 54.9 (±18.7) (p = 0.002) 1-month postoperatively but decreased below preoperative scores after 2 years (22.2 ± 18.1, p = 0.036).ConclusionPCTR is an efficient treatment for SGS, with low complication rates, a low rate of long-term restenosis and good vocal outcomes.

Study of joints in wooden structures with glue and screw connections for stiffening diaphragms and disks in multi-story buildings
Authors: Smirnov P. N. , Salimullin A. R. 
Published: February 2025

Introduction. The stiffness of prefabricated disks and diaphragms is considered a key parameter in designing multi-story buildings with wooden frames. Under the action of horizontal wind and seismic loads, the stiffness of wooden structures and their connections affects the distribution of forces among the structural elements and floors of the building. The stiffness and ductility of the joints in disks and diaphragms determine the dynamic characteristics of the building frame, such as the structural logarithmic decrement and damping ratio. The stiffness of vertical and horizontal joints influences the natural frequencies of multi-story buildings, while ductility affects the efficiency of energy dissipation during seismic events.Aim. To investigate the load-bearing capacity, stiffness, and ductility of joints with glue and screw connections for horizontal and vertical joints in stiffening diaphragms and disks in multi-story wooden buildings.Materials and methods. Following the methodologies outlined in State Standard 33082-2014, a comprehensive experimental study was conducted to assess the strength and deformation characteristics of connections using glued and screwed rods and joints based on them for inter-slab and inter-panel joints in stiffening diaphragms and disks made from laminated wood structures.Results. The load-bearing capacity, stiffness coefficients, and ductility of glue and screw connections with varying depths of screw rod insertion and joint connections for wooden disks and diaphragms were determined under various loading types (shear, tension, and compression).Conclusions. The analysis showed that the developed joints for wooden structures with glue and screw connections meet the requirements for high stiffness and can be utilized for joints in floor disks and wall diaphragms of multi-story wooden buildings. The obtained values of ductility coefficients for the tested joint connections indicate their capability to effectively dissipate energy during seismic impacts on the structure.

Introduction. Current Russian standards for the design of foundations on permafrost soils (SP 25.13330.2020) fail to sufficiently address the issue of accounting for negative forces during the thawing of the active layer when designing pile foundations in permafrost soils. As a result, designers face a choice either to account for negative forces, thereby increasing the reliability of the foundation design and its cost, or to neglect them, which reduces the cost of foundations but decreases their reliability. The present paper describes the results of studies on negative forces acting on the lateral surface of metal piles during seasonal thawing of permafrost soils represented by moderately saturated and fully saturated sands.Aim. To obtain a sufficient amount of experimental data for developing recommendations on accounting for negative friction forces acting on the lateral surface of pile foundations during the seasonal thawing of sandy soil.Materials and methods. The methodology involved conducting trough tests in a cooling chamber using pile models immersed in sand and suspended on crane scales. For tests, metal pipes of different lengths were immersed in sandy soils of medium and full water saturation. In addition, the study involved numeric thermotechnical calculations of the soil thawing rate and analytical calculations of the negative friction force based on SP 24.13330.2022 using reference values.Results. Proposals have been formulated to consider negative friction forces when designing pile foundations in thawing sandy soil.Conclusions. The analysis of experimental data revealed no negative forces on the lateral surface of piles during seasonal thawing of sandy soil.

Introduction. The jet grouting technology is considered to be one of the most relevant methods in geotechnics. Geotechnical structures based on this technology are hidden and require special control of the intended properties. Currently, the regulatory documentation primarily establishes control measures only after the completion of work on the stabilized soil that has gained strength. Such control methods has no impact on the results of the work but merely confirm it. The controlled influence on the results requires developing a method for operational process control in order to adjust the process in real-time and achieve the desired outcome. A solution to this issue may involve operational control of the stabilization quality based on the parameters of the soil-cement slurry discharged during jet grouting.Aim. To investigate control issues in soil stabilization using jet grouting based on the physical and mechanical characteristics of the soil cement slurry discharged during the stabilization process.Materials and methods. The study was conducted on samples obtained under laboratory conditions. The materials for the laboratory samples included fine, medium, and coarse sand; loam; clay; CEM 0 42.5N cement; water. Laboratory samples were created by mixing various compositions of the soil cement mixture, simulating the soil cement slurry that transforms into soil-cement during the hardening process. Studying the laboratory samples involved determining the density in a liquid state and the density and strength after hardening.Results. The study revealed the dependence of an increase in the strength of soil cement on a growth in the density of soil cement slurry while changing the ratio of components of the slurry composition.Conclusions. The conducted studies were instrumental in assessing the impact of the quantitative ratio of the components in the models of the soil-cement mixture (slurry) on its density and, as a result, on the strength and density of soil-cement samples.

Abstract
Whether the X-ray emissions of strong jet sources originate from disk+coronas or jets is still controversial. In this work, we constructed a strong jet sample containing 50 flat-spectrum radio quasars, 51 low-synchrotron-peaked BL Lac objects, and 18 intermediate-synchrotron-peaked BL Lac objects to explore the origin of X-ray emissions. Generally, blazars are the typical radio-loud active galactic nucleus with a powerful jet toward the observer, causing their broadband emissions to be boosted. By considering the Doppler boosting effect, we obtain the intrinsic radio–X-ray correlation and the fundamental plane (FP) of black hole activity for the strong jet sources: the intrinsic radio–X-ray correlation is

Our results suggest that the X-ray emissions of strong jet sources are dominated by the jets, but there may also be a small contribution from the disk. In addition, the radio–X-ray correlation and FP of strong jet sources do not have a significant dependence on the Eddington-ratio.
Le Mécanisme COVAX : une tentative d’intégration de principes éthiques dans l’ordre juridique international
Authors: Serrurier Enguerrand 
Published: February 2025

Élaboré en urgence pour répondre de façon équitable et multilatérale à la pandémie du SARS-Cov-2, le Mécanisme COVAX est l’une des branches de l’initiative internationale lancée par l’Organisation mondiale de la Santé (l’« Accélérateur ACT »), dédiée à la recherche, l’achat et la répartition mondiale des vaccins. Ce mécanisme est désormais opérationnel. L’objectif de couvrir les besoins en vaccination de 20 % de la population fragile des pays les plus vulnérables face à la COVID-19 (soit 1,3 milliard de personnes) est certes ambitieux ; trente-huit millions de vaccins ont été à ce jour distribués dans cent pays grâce à lui. Il est donc proposé d’en faire une analyse juridique, car le Mécanisme COVAX exprime en effet nombre de problèmes de la solidarité contemporaine (fondés sur l’éthique et les partenariats volontaires) tout en faisant progresser une conception transversale et unifiée de la vulnérabilité au niveau mondial.
