Reliability Determination of Bridge Span Based on Structural and Functional Approaches
Authors: Ogurtsov G. L. , Ermoshin N. A. 
Published: February 2025

Despite measures taken to improve the quality of design, construction and operation of bridge structures, failures in the structural elements of bridges do not decrease. This is largely due to the intensified traffic flow and aggressive effect of chemically-active atmospheric gases and deicing materials on structural materials. However, regulatory documents on the road and bridge design do not take these factors into account to justify their reliability and durability and suggest to use safety margin coefficients based on retrospective statistical data on traffic and bridge operation. The result is a contradiction between ensuring the bridge safety and scientific and methodological base for solving these issues. It is thus necessary to develop a method for predicting the bridge reliability, which takes into account the joint operation of its structural elements, stochastic nature, dynamic parameters of traffic flow, and a destructive effect of aggressive environment on the bridge during its service life.Purpose: The development of a methodological approach to the assessment and prediction of reliability indicators of reinforced concrete bridge spans.Methodology: The proposed method to determine reliability indicators of bridge spans is based on the mathematical apparatus for structural reliability functions of complex systems, determining the diffusion of liquids and gases and simulating the span operation.Research findings: The distribution density functions of superstructures obtained during the method implementation, taking into account the stochastic nature of the composition and intensity of traffic, technological processes of construction, maintenance of bridge structures and materials used, natural and climatic factors, allow to predict the duration of the inter-repair service of bridges, develop organizational, technical and constructive solutions to improve the bridge safety.

У технологічних процесах машинобудування для з’єднання одно- та різнорідних матеріалів усе частіше застосовують метод паяння в інертних газах за допомогою зварювальних півавтоматів. Цей метод ще називають MIG-паяння. Попри всі його переваги, оператори зварювального обладнання не мають чітких рекомендацій щодо вибору режимів роботи обладнання та їх впливу на параметри швів зварних з’єднань.
Дослідження процесу MIG-паяння сталі 09Г2С зварювальним півавтоматом Trans Puls Synergic (TPS) 2700 СМТ від Fronius проводили з використанням спеціального мідно-кремнієвого дроту CuSi3 діаметром 1,2 мм в захисному середовищі чистого аргону з використанням зварювальної колони, призначеної для виконання лінійних зварних швів з метою виявлення особливостей впливу режимів і параметрів технологічного процесу на форму та якість отримуваних з’єднань.
У результаті проведених досліджень встановлено, що процес MIG-паяння сталі за допомогою зварювального півавтомата апаратом Fronius TPS 2700 CMT має певні особливості налаштування технологічних параметрів на різних режимах його роботи. Синергетика джерела живлення дозволяє задавати основні параметри процесу в певних межах залежно від обраного режиму його роботи.
Найкраща якість MIG-паяння була досягнута при роботі зварювального півавтомата в режимах Synergic та СМТ. Для зварювання листової сталі товщиною 1…3 мм на цих режимах струм зварювання слід задавати в діапазоні 90…160 А при швидкості подачі дроту 3…5 м/хв відповідно. Також встановлено, що зі збільшенням швидкості переміщення пальника ширина шва зменшується, а отже, опуклість шва зростає.
У результаті досліджень сформовані рекомендації щодо налаштування зварювального півавтомата з врахуванням синергетичного ефекту його роботи.

Authors: Delgado Bruno Miguel , Lopes Ivo , Rodrigues Fátima , Neto Célia , Pereira Ana Seixas , Novo André 
Published: February 2025

INTRODUCTION: Heart Failure inpatients have a significant functional dependence, impairment of performance in activities of daily living and low exercise tolerance... The amount of Exercise is directly related to its benefits and the volume of exercise performed must be adjusted to safety issues. The aim of this study is to evaluate the volume of exercise performed and it’s relation with functional capacity and find a baseline volume level safe and effective.
METHODS: Quasi-experimental study involving 72 inpatients who performed an aerobic exercise training program. Volume of exercise was registered in terms of number of cycloergometer turns, meters walked, steps climbed and the total time exercising. Subjective perception of exertion was evaluated in every training session at beginning and in the end. Patients performed two 6-minute walking tests (6MWT).
RESULTS: 987 exercise sessions were performed. The majority of the patients were significant impaired: 81.9% are NYHA III and 73.6% present HFrEF. Patients achieved lower levels of perceived exertion throughout the inhospital stay: 6 (±3) (admission) and 2(±2) (discharge). Patients who performed more volume of exercise walked a higher distance in the discharge 6MWT.
CONCLUSION: A bigger volume of aerobic exercise is related to a better improvement on functional outcomes. An average of more than 10 minutes per session seems to be more effective in terms of improvement of the functional capacity.

Published: February 2025

This research explores the protective laws and enforcement of human rights in Indonesian correctional facilities, especially by observing systematic problems in exercising the ruling on prisoners' rights.Â This study uses a juridical-empirical method based on analyzing legal sources with additional field research to cover what legal contents advocate for in what contexts more effectively. It analyzes primary legal materials,including relevant legislation and gathers empirical data throughinterviews and direct observations. This approach allows for an enhanced understanding of the interplay between legal theory and practice to evaluate the legal framework of prisoners' rights protection critically. The findings reveal significant legal gaps, particularly regarding the unclear constitutional arrangements regarding the separation of powers in the execution of sentences as well as the protection of prisoners' rights. These issue are notably prevalent in correctional institutions in Central Java, which has been the case that the enforcement mechanism has not been running optimally. The analysis identifies systematic violations of prisoners' rights stemming from structural weaknesses in the legal relationships between correctional institutions, courts, and other law enforcement entities. As outlined in the examination of statutory interpretation and legal principles throughout this study, legislative reform is also necessary to better protect prisoners' rights, particularly concerning clarification of institutional authority and improved oversight mechanisms. These findings highlight the necessity for legal harmonization between human rights standards and correctional practices to increase the integrity of the Indonesian criminal justice system.

Published: February 2025

IntroductionPsoriatic arthritis (PsA) is a chronic immune-mediated inflammatory disease displaying heterogeneous symptoms. However, the association between the clinical heterogeneity of PsA and disease immunopathogenesis remains poorly understood complicating diagnostic precision. A knowledge gap remains on whether it is possible to distinguish the clinical PsA phenotypes on the immune cellular level. The primary aim of the study was to explore the differences in gene expression profiles comparing PsA patients without cutaneous psoriasis (PsA-only) and PsA patients with cutaneous psoriasis (PsA/PsC). The secondary aim was to describe the transcriptional patterns in PsA patients compared with healthy controls.MethodsThe study applied single-cell RNA sequencing (scRNAseq) using the BD Rhapsody™ Single-Cell Analysis System to evaluate peripheral blood mononuclear cells (PBMCs) from 70 PsA patients and 10 healthy controls. Differential expression (DE) analysis and gene set enrichment analysis (GSEA) were applied to evaluate differentially expressed genes (DEGs) and enriched signaling pathways, respectively.ResultsThe DE analysis and GSEA comparing PsA-only and PsA/PsC patients with healthy controls, respectively, revealed divergent results involving both innate and adaptive immune mechanisms, which might be associated with differences in the clinical phenotype. No DEGs were discovered in the direct comparison of PsA-only and PsA/PsC patients.DiscussionThe single-cell transcriptome profiling provided insight into the heterogeneity of PsA patients as the discovered DEGs and the GSEA did demonstrate differences in signaling associated with inflammation comparing PsA patients with and without cutaneous psoriasis.

Carlo Linati (Como 1878-1949) was a cyclist and traveller and at the same time one of the most active writers, translators and critics of the first half of the 20 th century. In 1919, he published one of the most beautiful bicycle rides in the Italian literature, following in the footsteps of Renzo, one of the main characters of Alessandro Manzoni’s novel The Betrothed . From Milan to Bergamo, following the Naviglio Martesana and the Adda, Sulle orme di Renzo
was a great success with the public and critics, stimulating reflection between geographical and literary spaces. After a century, the little book and the Lombard landscape deserve to be rediscovered, through the pages and by bicycle.
Influence of filler mixing technique on the properties of silica-filled natural rubber vulcanizates
Authors: Sony Athira , Kurian Thomas 
Published: February 2025

A simple process for the preparation of 40 parts silica incorporated dry natural rubber by latex stage master batching followed by quick coagulation and drying was developed. This environment friendly process avoids the loss of silica during mixing associated with the conventional dry rubber – filler mixing on an open two roll mill. The processing and the evaluation of the properties of the vulcanizates based on the dry rubber prepared by the latex stage filler incorporation technique shows improved scorch safety, mechanical properties, abrasion resistance and DeMattia flex resistance compared to a control formulation processed by conventional dry rubber -filler mixing process. The novel latex stage silica incorporation in natural rubber latex followed by quick coagulation and drying is effective at combining significant quantities of silica with natural rubber without the need of additional chemicals such as coupling agents for compatibility.
