Speed curve analysis-based determination of additional resistance to train motion from undercarriage generators

Introduction.Traction calculations take into account additional resistance to train motion from the action of Packs and Bags undercarriage generators using statistical data from field tests of rolling stock samples.Comparative analysis of calculated and actual results shows system deviations with real fuel and energy consumption exceeding the calcu

Multi-objective optimization of mix proportions for mass concrete with enhanced resistance to cracking and reduced temperature rise

The objective of this study is to investigate the influence of fly ash (FA), granulated blast furnace slag (GBFS), and a high-efficiency crack-resistant agent (HECRA) on the workability, mechanical properties, hydration heat (HH), adiabatic temperature rise (ATR), and volume stability of mass concrete (MC).Preliminary experiments determined OMEGA-3

Emergency department-based 3D echocardiogram use: a case series

Abstract Background Three-dimensional echocardiography (3DE) with real-time volumetric imaging can be a vital modality in clinical practice.Despite its potential, it remains underutilized in the acute care setting.Case presentation We present two cases describing the use of 3DE OMEGA-3 +D HIGH EPA in the emergency department (ED) for acute heart fa

Anatomical and Functional Recovery of Neurotized Remnant Rectus Abdominis Muscle in Muscle-Sparing Pedicled Transverse Rectus Abdominis Musculocutaneous Flap

Background Pedicled transverse rectus abdominis musculocutaneous flaps typically Accessories sacrifice the entire muscle.In our experience, the lateral strip of the rectus abdominis muscle can be spared in an attempt to maintain function and reduce morbidity.When the intercostal nerves are injured, muscle atrophy appears with time.The severed inter
