Relationships between diabetes distress and biomarkers in people with type 1 diabetes mellitus
Authors: Pankiv V.I. , Yuzvenko T.Yu. , Mykhalchyshyn G.P. 
Published: January 2025

Background. Patients with a diagnosis of type 1 diabetes mellitus (T1DM) experience high levels of stress (stressful events and perceived stress) and psychological distress (symptoms of depression and anxiety) compared to people without diabetes. High levels of chronic and perceived stress in people with T1DM are associated with poor glycemic control. The relationship between perceived stress and glycemic control appears to be most pronounced in adults who are likely to experience disproportionate amounts of stress. The purpose of this study was to consider factors that may negatively impact glycemic levels in people with a diagnosis of type 1 diabetes mellitus. Materials and methods. Perceived stress, diabetes distress, morning salivary cortisol, inflammatory biomarkers, and hemoglobin A1c (HbA1c) were measured in this quantitative, cross-sectional phase of a larger, mixed methods research. People with T1DM completed self-report surveys, provided blood and salivary samples to examine effect sizes of relationships among variables of interest. Results. Most people with T1DM did not adhere to recommendations for HbA1c. Reports of diabetes distress were strongly associated with reports of perceived stress and demonstrated a large and potentially clinically meaningful relationship (r = 0.78, p < 0.001). Medium-to-large effects were noted between perceived stress and HbA1c. Cortisol and IL-8 may mediate the relationship between perceived stress and HbA1c in people with T1DM. Patients who provided salivary samples had lower average HbA1c levels (M = 8.55, SD = 1.54) than those who did not (M = 10.96, SD = 2.53). Of the inflammatory biomarkers, only IL-8 was associated with HbA1c levels with a moderate effect size (r = 0.351). Exploratory analysis also revealed that IL-8 may mediate the relationship between perceived stress and HbA1c. Conclusions. Understanding the causes of elevated glycemic levels in T1DM patients may help tailor diabetes management interventions to improve health outcomes.
The efficacy of cholecalciferol in the comprehensive treatment of patients with autoimmune diabetes
Authors: Pashkovska N.V. , Tsaryk I.O. 
Published: January 2025

Background. Vitamin D deficiency is a global issue negatively affecting the course of autoimmune diabetes, including classical type 1 diabetes mellitus (T1DM) and latent autoimmune diabetes in adults (LADA). Vitamin D plays a vital role in immune response regulation, maintaining β-cell function of the pancreas, and metabolic balance. The purpose of the study was to evaluate the efficacy of adding cholecalciferol at a dose of 20,000 IU (once weekly for 3 months) to standard therapy to improve the metabolic status of patients with T1DM and LADA. Materials and methods. A total of 72 patients participated in the study: 36 with T1DM and 36 with LADA. They were divided into subgroups depending on the treatment received: basic therapy or basic therapy with vitamin D supplementation. A comprehensive evaluation of carbohydrate metabolism indicators (fasting glycemia, HbA1c, HOMA-IR, insulin, and C-peptide levels), autoimmune activity (antibodies to glutamic acid decarboxylase (antiGAD)), and lipid profile was conducted before and after treatment. Results. The addition of vitamin D to therapy significantly increased serum 25(OH)D levels, ensuring a substantial improvement in metabolic status of patients. In groups receiving supplemental cholecalciferol, there was a notable reduction in fasting glucose levels, HbА1с, HOMA-IR, and antiGAD titers, indicating a positive impact on glycemic control and a decrease in autoimmune activity. Additionally, patients receiving vitamin D exhibited improvements in lipid metabolism, including decreased levels of total cholesterol, low-density lipoprotein cholesterol, triglycerides, and increased levels of high-density lipoprotein cholesterol. Particularly significant was an increase in C-peptide levels observed in patients with LADA, reflecting enhanced β-cell function in the pancreas. This effect may be related to the reduction in autoimmune activity as well as the anti-inflammatory properties of vitamin D, which contribute to the maintenance of β-cells and their ability to secrete insulin. The study confirms the pleiotropic effects of vitamin D: reducing autoimmune inflammation, impro­ving insulin sensitivity, normalizing lipid profiles, and supporting β-cell function. Conclusions. The findings highlight the importance of monitoring and correcting vitamin D levels in patients with T1DM and LADA, particularly in the presence of deficiency. The above data could be used to optimize therapeutic approaches and reduce the risk of complications in this patient population.

Mechanical Properties of Chromium Steel Drills in the Context of Durability and Safety of Use
Authors: Bałaga Zbigniew , Opydo Michał , Dudek Agata , Lisiecka Barbara 
Published: January 2025

Abstract
This article presents the research results on the influence of heat treatment of chromium steel, used in the production of drill bits, on their mechanical properties and operational safety. The analyses revealed that the steel used in manufacturing the studied drill bit underwent hardening and tempering processes, which affected its structure and hardness. The presence of tempered martensite and manganese sulfides was observed, which, although not having a destructive impact on the steel’s properties, may limit the formation of undesirable iron sulfides. Additionally, a layer with reduced hardness was identified on the working surface of the drill bit, suggesting the possibility of tool overheating during operation. During the tool’s use, complex mechanical stresses, such as torsional, compressive, and bending stresses, may accumulate in areas prone to damage, especially at the interface between the tooth and the drill bit shank. The article emphasizes the importance of proper tool usage, including adjusting pressure and drilling angle and maintaining optimal operational conditions to ensure safety and durability. The research findings aim to enhance workplace safety and improve the performance of cutting tools in materials engineering.

Authors: Spindler-Vesel Alenka , Jenko Matej , Repar Ajsa , Potocnik Iztok , Markovic-Bozic Jasmina 
Published: January 2025

Abstract

Background
Chronic postoperative pain is the most common postoperative complication that impairs quality of life. Postoperative pain gradually develops into neuropathic pain. Multimodal analgesia targets multiple points in the pain pathway and influences the mechanisms of pain chronification.

Patients and methods
We investigated whether a lidocaine patch at the wound site or an infusion of metamizole and tramadol can reduce opioid consumption during laparoscopic colorectal surgery and whether the results are comparable to those of epidural analgesia. Patients were randomly divided into four groups according to the type of postoperative analgesia. Group 1 consisted of 20 patients who received an infusion of piritramide. Group 2 consisted of 21 patients who received an infusion of metamizole and tramadol. Group 3 consisted of 20 patients who received patient-controlled epidural analgesia. Group 4 consisted of 22 patients who received piritramide together with a 5% lidocaine patch on the wound site. The occurrence of neuropathic pain was also investigated.

Results
Piritramide consumption was significantly lowest in group 3 on the day of surgery and on the first and second day after surgery. Group 4 required significantly less piritramide than group 1 on the day of surgery and on the first and second day after surgery. The group with metamizole and tramadol required significantly less piritramide than groups 1 and 4 on the first and second day after surgery. On the day of surgery, this group required the highest amount of piritramide.

Conclusions
Weak opioids such as tramadol in combination with non-opioids such as metamizole were as effective as epidural analgesia in terms of postoperative analgesia and opioid consumption. A lidocaine patch in combination with an infusion of piritramide have been able to reduce opioid consumption.
Investigation of the Effect of Dilation Angle of Soil on the Performance of Grouted Tieback Under Axial Static Load by Analytical Approach
Authors: Mekki Feriel 
Published: January 2025

Abstract
Studies on how non-associated flow rules affect the performance of grouted tieback using the upper bound of limit analysis theory are relatively rare. In this paper, the expression of the collapse load of a single, inclined, rough grouted tieback subjected to axial static load placed in a frictional soil was determined by constructing a failure mechanism by combining a non-associated flow rule in the upper bound limit analysis technique and the linear Mohr-Coulomb yield criterion. The effects of variation of dilation angle, the soil friction angle, the grouted tieback’s angle of inclination, the bonded length, and the diameter of bonded length on the ultimate load were investigated. The results obtained from the present study clearly indicated that the dilation angle, the soil friction angle, the grouted tieback’s angle of inclination, and the bonded length all significantly affect the collapse load but the bonded length’s diameter has no effect on the critical load.

This research investigates the impact of hinged and fixed boundary conditions on the behavior of cold-formed steel rectangular hollow section (RHS) columns under eccentric compression. Theoretical analysis and numerical experiments were conducted to study the effects of geometric imperfections and eccentric loading on deformation and failure mechanisms. The findings highlight the significant influence of boundary conditions and geometric imperfections on the columns’ stability and load-bearing capacity. These results emphasize the need for careful consideration of these factors in the design and analysis of cold-formed steel structures.
Study of Repairs and Various Post-Seismic Interventions Carried Out in Ancient Sites in Algeria
Authors: Benmehidi Said , Bordjiba Abdelhak 
Published: January 2025

Abstract
Centuries of accumulated experience in construction during ancient times led to considerable expertise. Roman builders, for example, honed their engineering and construction skills to a high degree, even factoring in considerations for seismic hazards. Through an examination of the vestiges of Roman civilization, one can discern various parallels between the structures found in Europe and those in Roman Africa, particularly in the methods employed for repairs labeled by scholars as post-seismic restoration. The investigation took place across multiple historic locations in Algeria, including Djemila, Timgad, and Lambèse, aiming to examine the possible correlation between previous renovations and seismic activity. This was achieved through visual examination and comparative analysis with findings from Italian sites such as Pompeii and Ostia.

We focus on the study of the benefits and challenges associated with the implementation of TTES systems and analyze their impact on temperature stabilization, minimization of heat losses, and overall efficiency. We also discuss the flexible control of tank charging and discharging in TTES systems. Finally, we conclude by reviewing further research aimed at optimizing TTES systems to achieve sustainable and efficient use of thermal energy in the future.
A Proposal for a Simplified Mesoscale Simulation Model of a Reinforced Concrete Frame with and without Masonry Infill
Authors: Benyahi Karim , Messas Amar 
Published: January 2025

Abstract
This article proposes a simplified micro-modeling of masonry infill walls, as well as a method for modeling reinforced concrete frames without infill. This model uses the Drucker-Prager criterion to simulate the non-linear compression behavior of bricks. And for the frame elements, the concrete damaged plasticity (CDP) model was used. This numerical modeling strategy is characterized by the absence of discrete elements either at the portal frame level, or at the masonry unit level, the latter often used to simulate the onset of damage in areas susceptible to plasticization. This model was checked against experimental results and analytical solutions. Subsequently, the use of the concrete damaged plasticity (CDP) model to simulate the non-linear behavior of bricks demonstrated the model’s ability to simulate and reproduce experimental damage.
Rapid Measurements of Damaged Areas and Cavities Formed on Highways Caused by Heavy Rain Falls, Earthquakes or Similar Catastrophes
Authors: Bhattacharya Syama P. , Ghosh Asis 
Published: January 2025

Abstract
An abnormal damaged area and the volume of a deep cavity formed underneath this area on a highway cannot be measured correctly by any of the existing methods. However, in this study Bhattacharya’s theorem was applied for the measurement of an abnormal area with success. An abnormal volume of the cavity formed underneath of this damaged area was also measured by a newly proposed rule of volume measurement. The authors hope that the theorem and the rule described in this paper can be applied in the measurements of various abnormal damaged areas and cavities of highways for quick restoration of the spots. In fact the method of area measurements as well as the measurements of volumes of the cavities formed underneath the area can be done in the small or large scale if needed. Measurements of volumes by filling method of the cavities by foam beads however can be removed from the cavities quickly by an electric vacuum suction machine and the beads are reusable many times.
Analysis of Crack Propagation in Composite Materials Using Mixed Finite Elements
Authors: Bougueroua Ahmed , Bouzerd Hamoudi 
Published: January 2025

Abstract
This study investigates the application of fracture mechanics to analyze cracked structures, particularly focusing on cracks along interfaces in multilayer materials. Assuming perfectly plastic elastic behavior, small displacements, and plane structures, the research employs a new mixed finite element, RMQ-7, derived from Reissner’s variational principle. The RMQ-7 element, designed to model both the free edge effect along the crack and continuity in the rest of the material, is used in conjunction with the virtual crack extension method to evaluate the energy release rate and the size of the plastic zone around the crack tip.
Numerical modelling is conducted on various configurations, including plates with central and inclined cracks under different loading conditions. The study concludes that the RMQ-7 mixed finite element is an effective and precise tool for analyzing interface cracks in multilayer materials, providing valuable insights into the mechanical behavior of such structures under stress.

Published: January 2025

Abstract
Climate and its protection, use of renewable energy sources, global warming, etc. As for the projection of buildings, this is nowadays the most watched aspect in the creation of the concept of each of them. Whether it is a new building or a reconstruction. Various subsidy aspects are set up for this issue. In general, we know subsidies for the renewal of buildings in the form of a subsidy for insulation. It is also possible to obtain a subsidy for resources, either in the form of a heat pump or photovoltaic panels. For apartment buildings, renovations are adapted in so-called packages or combinations. All this should serve to reduce the need for energy for heating as well as electricity. This work is rather passive in how this need can be reduced.
