Finite Element Modelling of Circular Concrete-Filled Steel Tubular Columns Under Quasi-Static Axial Compression Loading

This paper presents a modified finite element analysis (FEA) model for predicting the axial compression strength of large-diameter concrete-filled steel tubular (CFST) stub columns, addressing the gap in research that has often focused on smaller diameters. The size effect, which significantly impacts the structural performance of large-diameter CFST columns, is a key focus of this study. The goal is to validate the accuracy and reliability of the modified FEA model by comparing its predictions with experimental data from the literature, specifically examining ultimate axial load capacity, failure modes, and deformed shapes. In addition to validating the model, this study includes a comprehensive parametric analysis that explores how critical geometric parameters such as the diameter-to-thickness (D/t) ratio and length-to-diameter (L/D) ratio affect the axial compressive behavior of CFST stub columns. By systematically varying these parameters, the research provides valuable insights into the load-bearing capacity, deformation characteristics, and failure mechanisms of CFST columns. Furthermore, the material properties of the steel tube—particularly its yield strength—and the compressive strength of the concrete core are investigated to optimize the design and safety performance of these columns. The results indicate that the FEA model shows excellent agreement with experimental results, accurately predicting the axial load-strain response. It was observed that as the diameter of the steel tube increases, the peak stress, peak strain, strength index, and ductility index tend to decrease, underscoring the size effect. Conversely, an increase in the yield strength and thickness of the steel tube enhances the ultimate strength of the CFST columns. These findings demonstrate the reliability of the modified FEA model in predicting the behavior of large-diameter CFST columns, offering a useful tool for optimizing designs and improving safety margins in structural applications.

Splitting tensile strength of shale cores: intact versus fractured and sealed with ureolysis-induced calcium carbonate precipitation (UICP)

AbstractUreolysis-induced calcium carbonate precipitation (UICP) is a biomineral solution where the urease enzyme converts urea and calcium into calcium carbonate. The resulting biomineral can bridge gaps in fractured shale, reduce undesired fluid flow, limit fracture propagation, better store carbon dioxide, and potentially enhance well efficiency. The mechanical properties of shale cores were investigated using a modified Brazilian indirect tensile strength test. An investigation of intact shale using Eagle Ford and Wolfcamp cores was conducted at varying temperatures. Results show no significant difference between shale types (average tensile strength = 6.19 MPa). Eagle Ford displayed higher strength at elevated temperature, but temperature did not influence Wolfcamp. Comparatively, cores with a single, lengthwise heterogeneous fracture were sealed with UICP and further tested for tensile strength. UICP was delivered via a flow-through method which injected 20–30 sequential patterns of ureolytic microorganisms and UICP-promoting fluids into the fracture until permeability reduced by three orders of magnitude or with an immersion method which placed cores treated with guar gum and UICP-promoting fluids into a batch reactor, demonstrating that guar gum is a suitable inclusion and may reduce the number of flow-through injections required. Tensile results for both delivery methods were variable (0.15–8 MPa), and in some cores the biomineralized fracture split apart, possibly due to insufficient sealing and/or heterogeneity in the composite UICP-shale cores. Notably in other cores the biomineralized fracture remained intact, demonstrating more cohesion than the surrounding shale, indicating that UICP may produce a strong seal for subsurface application.

Testing selected movement patterns using the ohmbelt

Over the last two decades, interest and the resulting need for objectification has grown steadily in the regulation of intra-abdominal pressure, coactivation of trunk muscles and biomechanics of stabilization of the lumbar region. Raising awareness of the research issue contributes to improving the prevention and therapy of various pathologies related to core stabilization. The aim of the study was to evaluate the usability of Ohmbelt in practice with complex movement patterns to accelerate the diagnosis of stabilization strategy of the lumbar region. The Ohmbelt system is a relatively new, non-invasive method for examination intra-abdominal pressure. In our study, we found that the use of the Ohmbelt system is possible in the examination of the stabilization strategy of the lumbar region in both static and dynamic positions. Based on our results, it is possible to use Ohmbelt for other complex movement patterns.

Fracture strength of direct occlusal veneers with different short fiber-reinforced composite cores and veneering materials: an in-vitro study

ObjectiveThe objective of this study is to evaluate the effectiveness of two different viscosities of short fiber-reinforced composite resin (SFRC) cores and two different viscosities of veneering composite resins on the fracture strength of direct occlusal veneers.Materials and methodsOne maxillary premolar was virtually prepared for an occlusal veneer and printed into resin dies. In total, (n = 48) resin dies were printed and assigned into three groups according to the type of core material of the occlusal veneer; mono-structured without a SFRC core, a high viscosity SFRC core, and a low viscosity SFRC core. Each group was re-divided into two subgroups (n = 8) according to the veneering composite resin; packable composite resin and injectable composite resin. Mono-structured and bi-structured direct occlusal veneers were fabricated on the resin dies using the mentioned core and veneering materials with the occlusal replica technique. Fracture strength was evaluated using a universal testing machine and the mode of failure was inspected. Statistical analysis to compare the core and veneering materials was performed using independent t test (P ≤ 0.05) and one-way ANOVA followed by tukey’s post hoc test (Pa ≤ 0.0166) when appropriate. Interactions between subgroups were tested using two-way ANOVA, and one-way ANOVA was used to compare all subgroups followed by tukey’s post hoc test (Pa ≤ 0.0033). Intergroup comparison between failure modes were performed using chi square test (Pa ≤ 0.0033).ResultsThe presence of a SFRC core significantly improved the fracture strength of the specimens. There was no significant difference between the fracture strength of high viscosity SFRC and low viscosity SFRC cores. Specimens veneered with injectable composite resin had significantly superior fracture strength compared to packable composite resin. Additionally, there was a weak correlation between fracture strength and mode of failure.ConclusionShort fiber reinforced composite resin significantly increases the fracture strength of direct occlusal veneers. Injectable composite resin has significantly higher fracture strength than packable composite resin as veneering materials of direct occlusal veneers.Clinical relevanceBi-structured direct occlusal veneers fabricated of injectable composite resin with low viscosity SFRC cores can withstand high masticatory forces in stress-bearing areas.

Evaluate the effect of exercise core strength training on antioxidant enzyme activity in women from a biomechanical perspective

At present, the incidence rate of chronic diseases is increasing year by year. A variety of antioxidant enzymes in the human body, such as Superoxide Dismutase (SOD), Nitric Oxide Synthase (NOS), Glutathione Peroxidase (GSH Px), Malonic Dialdehyde (MDA) and Catalase (CAT), help to inhibit the generation of oxygen free radicals and play a certain role in preventing the occurrence of chronic diseases. The research on the activity of antioxidant enzymes and the delivery of antioxidant drugs has gradually become the focus of relevant scholars. The physical quality of women is lower than that of men, so it is of great practical significance to study the antioxidant enzyme activity of women. Therefore, this paper explores the influence of exercise core strength training on women’s antioxidant enzyme activity from a biomechanical perspective and concludes that core strength training can improve female students’ SOD content level by 2.58%, and can improve female students’ NOS content level, GSH-Px content level, and MDA content level. Sports core strength training has a positive impact on women’s antioxidant enzyme activity.

Impact of strength training on the prevention of orthopedic injuries in sports: a literature review.

Introduction: The perception of physical activity has evolved, influenced by urbanization, media, and public health initiatives. While regular physical activity offers health benefits, musculoskeletal injuries in athletes remain a concern, often going unnoticed due to subtle symptoms. Preventing these injuries is crucial, with strength training (ST) emerging as a strategy to enhance stability and reduce injury risk. Purpose of the Study: This review examines the impact of strength training on preventing orthopedic injuries in athletes, focusing on mechanisms like muscle strengthening, joint stabilization, improved endurance, and correcting imbalances. It evaluates research on ST's effectiveness in preventing knee, ankle, hip, back, and upper limb injuries. Methodology: A comprehensive search of databases, including PubMed, Scopus, and Google Scholar, was conducted using keywords such as "strength training," "orthopedic injury prevention," "musculoskeletal stability," "injury risk reduction," and "sports injuries." Results: Strength training plays a key role in preventing sports injuries by enhancing muscle strength, joint stability, and endurance, addressing musculoskeletal weaknesses and imbalances. Studies show ST significantly reduces knee, ankle, hip, and back injuries. For instance, knee injuries are prevented by strengthening the hip abductors and quadriceps, while ankle injuries are mitigated by improving core and lower limb strength. ST also prevents injuries in "overhead sports" by enhancing shoulder stability. Keywords: strength training, orthopedic injury prevention, musculoskeletal stability, sports injuries, injury risk reduction.

Method to improve the bonding strength of polyethylene terephthalate core with glass fiber reinforced skins in a sandwich composite

AbstractComposite materials provide an alternative to conventional structural materials. Sandwich composites show high bending strength and superior strength‐to‐weight ratio. The major drawback in sandwich composites is debonding of skin from core, that causes failure of a component during the usage at different loads. To overcome this issue, the current work identifies a solution of introducing nylon screws (M6 × 32) to adhere firmly the skins consisting of glass fibers with PET (Polyethylene Terephthalate) core. The sandwich composites were fabricated by vacuum infusion process. Two flat sandwich composites were fabricated; one with nylon screws placed perpendicular to the skin and the other a plain sandwich composite. Mechanical characteristics of the specimens such as fracture toughness, flexural strength and shear strength were studied. Specimens with nylon screws showed 21.78% more fracture toughness compared to plain specimen. The presence of screws acts as hindrance to the propagation of cracks in the interfacial region resulting in the enhancement of debonding resistance of the specimens. Also, sandwich specimens with nylon screws exhibited 136% and 142% improvement in flexural and shear strength respectively when compared to plain sandwich specimens. The investigation of scanning electron microscope (SEM) images of tested specimens indicates strong interfacial bonding between skin and the core of specimens with nylon screws.Highlights Introduction of light‐weight nylon screws in z‐direction enhanced the bonding between face sheets and foam core. Sandwich composites with nylon screws exhibited superior bending and shear strength compared to plain specimens. Crack propagation in the interfacial region is restricted by the presence of nylon screws. Investigation of fractured specimens indicated a strong interfacial bonding in the specimens with screws.

A newly identified photosystem II Subunit P gene TaPsbP4A-1 in Triticeae species negatively regulates wheat powdery mildew resistance

The photosystem II (PSII) Subunit P (PsbP) protein is a component of its oxygen-evolving complex, which can oxidize water to produce oxygen using light energy and is critical to the core components and stability of PSII. Using the whole-genome information, the PsbP genes of 10 plant species were comprehensively identified. The expression patterns of wheat PsbPs under Blumeria graminis f. sp. tritici (Bgt) infection were assessed using qRT-PCR, and the functions of TaPsbPs in wheat powdery mildew resistance were studied using barley stripe mosaic virus-induced gene silencing. In total, 122 PsbP genes were divided into 8 classes with similar gene structures. No tandem repeat events were identified in wheat PsbP, suggesting that the PsbP genes in common wheat were donated by its diploid progenitor species. The expression levels of TaPsbP2A-1, TaPsbP3A-1, TaPsbP4A-1, TaPsbP4A-2, and TaPsbP7A-2 were induced by Bgt. The silencing of TaPsbP4A-1 increased the resistance of common wheat ‘Bainong AK58’ to Bgt. This study provides valuable information for functional and evolutionary research on the PsbP gene family.

Effects of percussive massage therapy on fascia echo intensity and fascia thickness in firefighters with chronic non-specific low back pain: a randomized controlled trial

BackgroundChronic non-specific low back pain (CNSLBP) is prevalent among firefighters and may negatively affect their job performance. Alterations in the thoracolumbar fascia (TLF) structure are associated with CNSLBP. Percussive massage therapy (PT) has demonstrated potential in modifying fascial properties and alleviating pain. However, its effects on TLF structure in CNSLBP patients have not been thoroughly investigated. This study evaluates the effects of 6 weeks of PT on TLF echo intensity, thickness, pain, and disability in firefighters with CNSLBP, utilizing ultrasound imaging as a primary assessment tool.MethodsThis six-week randomized controlled trial involved 38 firefighters with CNSLBP. Participants were randomly assigned 1:1 to either the PT group (receiving PT and core stability exercise) or the control group (receiving only core stability exercise). TLF echo intensity and thickness were measured using ultrasound imaging, and disability was assessed using the Roland-Morris Disability Questionnaire (RMQ) at baseline and post-intervention. Pain was measured using the Visual Analog Scale (VAS) at baseline, immediately after the first intervention, three weeks post-intervention, and post-intervention. Paired t-tests were conducted to analyze within-group changes in RMQ and ultrasound data, while ANCOVA was used to assess between-group differences, and repeated measures ANOVA for VAS scores.ResultsParticipants in the PT and control groups were aged 26.6±4.1 and 23.6±1.7 years, respectively, with BMI of 23.1±1.8 and 21.8±1.2 kg/m². The PT group showed significant reductions in bilateral TLF echo intensity post-intervention (left side: mean difference -6.4, 95% CI -9.7 to -3.1, p < 0.001, effect size 0.67; right side: mean difference -7.6, 95% CI -11.8 to -3.3, p < 0.01, effect size 0.60). Changes in TLF thickness were not statistically significant (p > 0.05). The PT group demonstrated significantly lower VAS scores than the control group (mean difference - 0.626, 95% CI -1.087 to -0.165, p = 0.009, effect size 0.63). RMQ scores decreased by -1.3 (95% CI -2.1 to -0.4, p < 0.01, effect size 0.5).ConclusionSix weeks of percussive massage therapy significantly reduced thoracolumbar fascia echo intensity, alleviated pain, and improved functional disability in firefighters with chronic non-specific low back pain, but was not effective in altering fascia thickness. Percussive massage therapy emerges as an effective and safe strategy for managing chronic non-specific low back pain in firefighters.Trial registrationRetrospectively registered in Thai Clinical Trials Registry (TCTR20221223001) on December 22, 2022.

Ballistic characteristics of ceramic core sandwich structures

The ceramic core sandwich structure (CCSS) is a lightweight material with advantages of high anti-ballistic impact performance, high energy absorption and high specific strength. The ballistic performances of the CCSS with metal face plates hit vertically by projectiles with the nose shapes of conical, flat, and hemispherical are studied analytically and numerically in this paper. Based on the principle of energy conservation, an analytical model of ballistic characteristics of the sandwich ceramic core structure is developed. Numerical calculations are conducted, and the numerical model has been verified by experimental results from references by others. In addition, the analytical results agree well with finite element results. The effects of shape of projectile head, the thickness ratio of three plates of CCSS, and the ratio of shear strength of ceramic core to yield strength of metal face plates on the ballistic characteristics of the CCSS are discussed. It is shown that the conical-nosed projectile achieved the highest ballistic limit velocity (BLV) and the sharper nose increases the normal stress at the impact area thereby enhancing the BLV. The thickness of the ceramic core significantly influences the resistance of the CCSS and the thicker ceramic core enhances the ability of CCSS to absorb kinetic energy from the projectile. Furthermore, an appropriate increase in the yield strength of face plates can enhance the anti-ballistic impact performance of the CCSS. These insights have practical implications for the design of protective systems in military and civilian applications, where optimizing materials for impact resistance is crucial.

Effects of adding core stability training to conventional rehabilitation protocol on shoulder function after rotator cuff repair

Background. Rotator cuff tear (RCT) is a prevalent cause leading to shoulder disability and is widely recognized as one of the primary causes of pain as well as dysfunction in the shoulder. The core stabilization exercise program improved the strength of the shoulder muscles. The core stability training (CST) may be utilized during the early phases of shoulder rehabilitation. Purpose. To assess the impacts of adding CST to the conventional rehabilitation protocol on function, proprioception, as well as range of motion (ROM) of shoulder joint following rotator cuff repair (RCR). Methods. Fifty-two participants after RCR were assigned to two groups in a random manner; group I (n = 26) and group II (n = 26). Participants in groups I and II were engaged in a conventional rehabilitation protocol for 12 weeks after RCR. Group II additionally performed CST after the 8th week until the 12th week of RCR. Outcome measures were shoulder function using the Arabic shoulder pain and disability index (SPADI), shoulder joint position sense (JPS) (proprioception accuracy through detecting absolute angle of error) using digital inclinometer, ROM in shoulder flexion, abduction, internal rotation, as well as external rotation using the digital inclinometer. Unpaired t-test, chi square, and MANOVA test were implemented for data analysis. Results. Compared to the pre-treatment condition, the post treatment results revealed that there were statistical substantial improvements (p &lt; 0.05) in SPADI score, absolute angle of error, and ROM flexion, abduction, external rotation and internal rotation) in both groups, even though there were substantial differences among both groups at all post-treatment measures (p &lt; 0.05) in favor of group II. Conclusion. Incorporating CST into the conventional rehabilitation protocol after RCR leads to notable enhancements in shoulder joint function, proprioception, and ROM for flexion, abduction, internal rotation, as well as external rotation.

Impact of three weeks of integrative neuromuscular training on the athletic performance of elite female boxers.

To investigate the effects of integrative neuromuscular training (INT) on the athletic performance of elite female boxers. A before-and-after controlled experiment was conducted on 37 elite Chinese female boxers (Age: 26.00±3.11 years). All included athletes have competed at the international level. The INT intervention was administered 11 times per week for 3 weeks. This training includes strength training, explosive training, core stability, agility exercises, high intensity intervals and sprint intervals. Basic physical fitness tests, including the deep squat and bench press one-repetition maximum (1RM), vertical long jump, 30 m sprint run, 400 m run, 3,000 m run, 1-minute hexagonal jump, and 3-minute double shake; as well as specialized striking ability tests, including single-punch striking and 10-second, 30-second, and 3-minute continuous punching, were conducted before and after the intervention. Compared with pre-intervention baseline data, significant differences were found in the athletes' post-intervention baseline physical fitness, including squat and beach press (1RM), vertical jump, 30 m sprint run, 400 m run, 3,000 m run, 1-minute hexagonal jump, and 3-minute double shake (p<0.05). Additionally, 10-second, 30-second, and 3-minute continuous punching were significantly different compared with pre-intervention (p<0.05). However, no significant differences were found in single punch power (p>0.05). The 3-week INT can significantly improve the maximum strength, vertical explosive power, linear acceleration, agility, and continuous punching abilities of Chinese elite female boxers. The use of INT in physical training may enhance their athletic performance.
