Distal biceps tendon repair: outcome and complications with single incision anchor fixation.

The purpose of this study is to evaluate the functional outcome and quality of life in distal biceps tendon repair with single incision technique and anchor fixation method. A retrospective cohort study was made of patients with complete distal biceps tendon rupture. The chosen repair method was single incision technique with anchor fixation. The outcome was assessed with functional testing of the elbow with strength and ROM. Additionally Mayo elbow performance index, Oxford elbow score, Disability arm hand shoulder questionnaire and patient rated elbow evaluation scores were used to evaluate quality of life. Of the 28 patients, the average strength in flexion and supination was decreased with 91% and 89% of the strength compared to the non-injured arm. ROM was preserved in flexion, extension, supination and pronation. The mean scores for quality of life evaluation were MEPS = 96 ± 7.8, OES = 46.8 ± 1.9, DASH = 1.0 ± 1.9 and PREE = 2.0 ± 3.6. LABCN injury was the most common temporary complication with 30% followed by pain with 23%. Two patients were identified with HO and 1 patient was identified with median nerve injury. There were no cases of radioulnar synostosis and PIN injury. Overall strength in flexion and supination were slightly decreased with preserved ROM. Patients reported nearly perfect quality of life as demonstrated with the scores. The complications rate was high with mainly minor complications. Distal biceps tendon repair with single incision technique and anchor fixation overall leads to a very satisfying outcome.

Experimental study on multiple self-healing and impact properties of 2D carbon fiber fabric-reinforced epoxy composites with shape memory properties

Fiber-reinforced thermoset polymers are widely used in aerospace as a material with excellent performance. However, for the low-velocity impact damage to which they are most susceptible, existing repair methods are difficult to maintain the aerodynamic performance of the components (back to its pre-damage shape) after repair. In this study, the multiple impact deformation recovery, internal damage healing, and post-repair impact properties of epoxy-PCL (ε-caprolactone) 2D carbon fiber fabric-reinforced polymers with shape memory and self-healing properties were investigated. The material is manufactured using a hot press tank-prepreg process, curing at 160 degrees for 3.5 hours at 6 atmospheres. The results show that the incorporation of thermoplastic PCL into the composite matrix can enhance the self-healing ability and impact resistance of the material. Composites after lower energy impacts retain their structural integrity and mechanical properties after healing. Materials can recover effectively from a single impact, but repeated impacts can lead to more extensive damage, which makes healing more difficult and causes a decrease in Healing efficiency. The shape memory effect of composites can restore plastic deformation caused by impact, which highlights the potential of shape memory smart composites for aerospace applications.

The vascularized dermal fat flap is a relatively reliable repair method for soft defects in Oral and Maxillary Area.

Performance of the polyurethane foam injection technique for road maintenance applications

Road infrastructure plays an important role in strengthening transportation and driving the economic advancement of countries. However, the increasing traffic volume has accelerated road deterioration, particularly at critical points like bridge-road junctions. Traditional repair methods involving demolition and reconstruction lead to extended closures and high costs. This study explores the polyurethane (PU) foam injection technique as an alternative solution, which can reduce both repair time and costs. The research evaluates the application of PU foam in various road projects across Thailand, highlighting its ability to repair pavement surfaces and structures, even in severely damaged areas. Despite its advantages, the use of PU foam faces challenges due to a lack of standardized quality control. This paper proposes a set of working guidelines for PU foam injection, aimed at key stakeholders such as the Department of Highways, the Department of Rural Roads, and the Department of Local Administration. The findings underline the importance of establishing standardized methods to ensure the long-term effectiveness of PU foam in road maintenance. Future research should focus on refining these guidelines for diverse road conditions to support the sustainable development of national transportation infrastructure

Design and Optimization of Elliptical B-shaped Sleeve Configuration for Oil&Gas Pipeline

Abstract Affected by external loads or pipeline corrosion, oil & gas transmission pipelines may encounter safety hazards during service. In terms of defect repair, both domestic and foreign standards currently stipulate that the permanent repair method is B-type sleeve or tube replacement. Compared to the costly tube replacement, B-type sleeves are undoubtedly the preferred choice for economy and safety. However, due to installation size limitations, conventional sleeves are difficult to repair large deformation defects such as wrinkles and buckling in oil and gas pipelines. This study aims at developing, designing, and optimizing a B-type sleeve for welding repair of irregular defects in oil and gas pipelines. By designing irregular B-shaped sleeves with different curve configurations, the stress levels and concentration coefficients of irregular sleeves at different defect heights and sleeve lengths are calculated. The optimal pumpkin shaped and elliptical curve sleeve configurations are selected as the repair solutions for irregular sleeves. Under the existing limitations of machining and detection accuracy, pumpkin shaped irregular sleeves can be prioritized for application in engineering, while elliptical curve sleeves are considered as alternative solutions.

Research Progress and Development Trend of Treatment Methods for Annular Pressure in Gas Storage Caverns

Abstract In recent years, pressure in the annulus of gas storage reservoir injection wells has become increasingly common. This presents a significant challenge to the safe and efficient operation of gas storage reservoirs and the integrity of injection wells. This paper presents a systematic introduction to the prevention and control measures of annular pressure. The introduction is based on research into the development status of prevention and control methods both domestically and internationally. The measures mainly include two aspects. Firstly, for the sealing failure of the tubular column, the differential pressure activated blocking agent is used for management. Secondly, for the sealing failure of the cement ring, the sealing agent is managed by extruding cement, resin, and other blocking agents. The text analyses the advantages and disadvantages of the treatment technology in depth, in combination with existing research. The repair methods for gas storage reservoir annulus with pressure have problems such as insufficient construction conditions, poor implementation effect, and limited types of blocking agents available. Additionally, the different working conditions and performances of the reservoir annulus are taken into account. To ensure high efficiency and cost-effectiveness, we propose a new method for treating annulus pressure. This involves repairing any damage to the cement ring, restoring the production packer’s seal, and rebuilding the integrity of the old wellbore. By doing so, we can guarantee the safety of gas storage reservoirs throughout the entire injection and production life cycle. It is important to maintain the integrity of the old wellbore to ensure the safety of gas storage during injection and extraction.

Evaluation of healing after arthroscopic repair of lateral meniscal tears around the popliteal hiatus

BackgroundThe popliteal hiatus stabilizes the lateral meniscus (LM). Variable failure rates for LM repairs have been reported in knees with lateral meniscal tears (LMTs), which may be attributable to low vascularity around the popliteal hiatus. An effective repair method is essential to enhance the biological healing and stability of LMTs around the popliteal hiatus. HypothesisArthroscopic repair of LMTs, including the popliteus tendon around the popliteal hiatus, is expected to produce a low reoperation rate and effective treatment, both clinically and radiographically. Material and methodsFrom June 2011 to August 2020, 93 patients (mean age 27.9 ± 13.5 years) who underwent arthroscopic repair of LMTs including the popliteus tendon around the popliteal hiatus were enrolled. Patients with LMTs were divided into three groups: isolated LMTs, discoid LMTs, and LMTs with ACL injury. Patients had a minimum clinical follow-up of 2 years (mean 37.9 ± 19.3 months) and Tegner activity, Lysholm knee, and Hospital for Special Surgery (HSS) scores were evaluated for all patients. The widths of the popliteal hiatus and LM extrusion were measured on the sagittal and coronal planes using preoperative and postoperative magnetic resonance imaging (MRI). ResultsThe Tegner activity (2.6 ± 1.2–4.5 ± 1.3), Lysholm (67.9 ± 14.2–88.1 ± 6.4), and HSS scores (79.8 ± 11.5–93.7 ± 5.1) were significantly improved in all knees (p < 0.001). The width of the popliteal hiatus measured on MRI was significantly decreased, when comparing the preoperative and postoperative MRI for all knees (sagittal plane, 2.9 ± 1.4–1.5 ± 0.5 mm; coronal plane, 3.8 ± 2.5 to 1.9 ± 1.0 mm) (p < 0.05). The LM extrusion measured on the sagittal plane of postoperative MRI was also significantly reduced after arthroscopic repair (24.8 ± 3.1–23.7 ± 2.8 mm) (p = 0.001). Five reoperations (5/93, 5.3%) were performed, suggesting a clinical failure. ConclusionArthroscopic repair of isolated, discoid and post-traumatic LMTs including the popliteus tendon around the popliteal hiatus, is an effective surgical treatment for LM stabilization.

Analysis of Measurements in Microwaves Oven with High Level of Non-Ionizing Radiation (NIR) Before and After Repair

Non-ionizing radiation is the subject of several applications, such as the microwave oven, which is very popular. Its use is characterized by direct user operation and reduced distances between users and the NIR source. Therefore, the level of human exposure in this scenario deserves attention as it is a potential cause of biological effects. In this sense, this paper presents the measurement of a microwave oven with a high level of NIR (above the limit defined by the standard) before and after two types of suggested repairs: the use of epoxy putty (Repair 1) and the replacement of the external surface of the oven (Repair 2). The definitions of measurement methodology, based on FDA and INMETRO standards, are presented and discussed. Finally, we describe an analysis of the efficiency of these repair methods aiming at the safety operation.

An experimentally validated thermomechanical model for a parametric study on reducing residual stress in cast iron repair welding

Remarkable casting properties and superior mechanical characteristics of cast iron make it an ideal material for a wide range of industrial applications. However, the production of cast iron components may result in the formation of cracks and defects, posing a significant threat to their structural integrity. Repair welding is a promising solution to resolve cast iron production defects. However, repair welding cast iron components poses unique challenges that stem from residual stress (RS) formation and the possibility of cracking during the repair process. Moreover, research on cast iron repair is scarce. To overcome these challenges, this paper presents a thermo-mechanical model validated by experiments to reduce RS in cast iron repair welding through the optimization of welding parameters and weld sequences as well as the geometry of the repair area. An experimental bead-on-plate weld is set up in order to validate the developed thermo-mechanical model. The temperature distribution in the weld is measured using thermocouples placed around the weld line. An X-ray diffraction technique is used to measure the axial and transverse RS at different points around the weld line. The developed finite element model is employed to simulate the repair welding process and analyze the effect of inter-pass temperature, the number of welding passes, welding sequences, and groove geometry on the RS. The numerical approach applied in this study provides a framework for repair welding optimization of cast iron and other materials, fostering the development of more efficient and reliable repair methods for industrial applications.

An Automatic Software Defect Repair Method Based on Multi-Objective Genetic Programming

Due to the explosive growth of software quantity and the mixed ability of software developers, a large number of software defects emerge during the later stages of software maintenance. The search method based on genetic programming is one of the most popular in search algorithms, but it also has some issues. The single-objective approach to validate and select offspring patches without considering other constraints can affect the efficiency of patch generation. To address this issue, this paper proposes an automatic software repair method based on Multi-objective Genetic Programming (MGPRepair). Firstly, the method adopts a lightweight context analysis strategy to find suitable repair materials. Secondly, it decouples the replacement statements and insertion statements in the repair materials, using a lower-granularity patch representation method to encode the patches in the search space. Then, the automatic software defect repair is treated as a multi-objective search problem, and the NSGA-II multi-objective optimization algorithm is used to find simpler repair patches. Finally, the test case filtering technique is used to accelerate the patch validation process and generate correct patches. MGPRepair was experimentally evaluated on 395 real Java software defects from the Defects4J dataset. The experimental results show that MGPRepair can generate test case-passing patches for 51 defects, of which 35 defect patches are equivalent to manually generated patches. Its repair the efficiency and success rate are higher to other excellent automatic software defect repair methods such as jGenProg, RSRepair, ARJA, Nopol, Capgen, and SequenceR.

Model test of in-situ remediation for heavy metal-contaminated clayey soil by artificial freezing and shaft washing

The low permeability of clayey soil and the pressure of liquid extraction and injection tend to form preferential flow paths in the soil, diminishing the remediation efficiency of shaft washing. Therefore, a new in-situ repair method combining artificial freezing and shaft washing is proposed. Using Pb and Cd contaminated clayey soil as the research object, in-situ model tests of different eluent types, concentrations, and suction modes were conducted to investigate the removal rate of heavy metals and the distribution of temperature and water field. The results demonstrated that the artificial freezing method can effectively induce the water (eluent) migration from the unfrozen zone to the freezing front. Besides, it effectively resolved the issue of poor washing efficiency caused by preferential flow between the extraction and injection wells during the extraction process. After five freeze-thaw cycles, the removal rate of Pb and Cd reached 46.16 % and 59.04 %, respectively. The combination of artificial freezing and plastic drainage plate technology merges artificial freezing and shaft washing methods to achieve the remediation of heavy metal-contaminated soil, providing a reference for the in-situ remediation of heavy metal-contaminated clayey soil.

Meta-Hybrid: Integrate Meta-Learning to Enhance Class Imbalance Graph Learning

The class imbalance problem is a significant challenge in node classification tasks. Since majority class samples dominate imbalanced data, the model tends to favor the majority class, resulting in insufficient ability to identify minority classes. Evaluation indicators such as accuracy may not fully reflect the model’s performance. To solve these undesirable effects, we propose a framework for synthesizing minority class samples, GraphSHX, to balance the number of samples of different classes, and integrate the XGBoost model for node classification prediction during the training process. Conventional graph neural networks (GNNs) yielded unsatisfactory results, possibly due to the limited number of newly generated nodes. Therefore, we introduce a meta-mechanism to deal with small-sample problems, and employ the meta-learning approach to enhance performance on small-sample tasks by learning from a large number of tasks. An empirical evaluation of node classification on six publicly available datasets demonstrated that our balanced data set method outperforms existing optimal loss repair methods and synthetic node methods. The addition of the XGBoost model and meta-learning improves the accuracy by more than 5% to 10%, with the overall accuracy of the improved model being 15% higher than that of the baseline method.

Influencing Factors, Design Methods, and Buoyancy Reduction Measures for Basement Anti-Flotation Engineering

Basement anti-flotation design is crucial in modern urban construction. An increase in groundwater buoyancy can cause basement structures to uplift, leading to structural instability or even damage. To ensure the stability and safety of underground structures under various hydrogeological conditions, anti-flotation design must comprehensively consider factors such as construction, design, supervision, structure, and hydrology. During construction, improper dewatering measures or unreasonable construction progress may lead to an abnormal rise in groundwater levels, increasing the risk of anti-flotation. Design considerations must include sufficient safety margins, supervision must fully recognize the impact of groundwater, and the structural dead load must be adequate. Anti-flotation stability verification includes both overall and local anti-flotation, involving the calculation of groundwater buoyancy, structural self-weight, and overburden, and selecting appropriate anti-flotation stability safety factors. The assessment and selection of the anti-flotation design water level are also critical. Common anti-flotation measures include adding counterweights, tension-resistant piles, compression and tension-resistant piles, and hydro-pressure reduction methods, while reinforcement and repair methods include epoxy resin grouting and steel plating reinforcement. Through systematic analysis and comprehensive research, scientific basis and technical support are provided for anti-flotation design, enhancing design efficiency and reliability and ensuring the safety and stability of underground spaces. Future research will develop more accurate calculation methods, improve design standards, and explore new anti-flotation technologies and materials.

Pengaruh Ukuran Kawat dan Jarak Alur Stator Terhadap Nilai Arus Starting Motor Induksi 3 Fasa

&lt;p&gt;&lt;strong&gt;The use of electric motors in industry often experiences damage caused by several things, including high &lt;em&gt;starting&lt;/em&gt; current surges, overload or full load, loss of one phase in the electric motor, and other causes of damage to the 3-phase motor. The main problem that occurred in this research was damage caused by high &lt;em&gt;starting&lt;/em&gt; currents, where in the case study many 3-phase motors were used to drive factory machines. The use of 3-phase motors to drive factory machines is often damaged by unstable currents in the machines. This is because the time and workers for monitoring are very minimal and the materials for repairing machines are inadequate. In this way, the solution for repairing a 3-phase motor is to replace and rewind the damaged motor so that it can be used again. This research aims to find a solution on how to reduce high &lt;em&gt;starting&lt;/em&gt; currents in 3-phase motors by utilizing the influence of replacing damaged induction motor components as well as repair methods used in &lt;em&gt;starting&lt;/em&gt; when &lt;em&gt;rewinding&lt;/em&gt; 3-phase motors. The research results from the groove distance with a wire size of 0.90 mm showed that the groove distance of 9, 9, 8 was 29.3, and at a distance of 10, 10, 10 it had a current of 31 A with no-load testing and recommended groove distances of 10, 10, 10. Next, testing wire sizes of 0.75 mm and 0.90 mm with distances of 10, 10, 10, and 9, 9, 8 without load obtained 26.1 A and 27.4 A while 0.90 mm was 30, 7 A and 28, 1 A. The load was 43.5 A and 43.9 A, while 0.90 mm was 51.3 A and 49.3 A. From the test results, the largest current decrease was at a distance of 10, 10, 10 with a wire size of 0.75 mm. &lt;/strong&gt;&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Keyword - &lt;em&gt;3 Phase Induction Motor, Groove Spacing, Starting, Wire Size.&lt;/em&gt;&lt;/strong&gt;&lt;/p&gt;

Sewing: A New Quilting Suture Method for Nasal Septum Repair

A deviated nasal septum leads to congestion and headaches. Surgery is the primary treatment, requiring careful postoperative septum positioning to prevent bleeding and hematoma. The study compared this method with nasal packing and traditional nasal septum suturing regarding surgical time, patient pain, nasal obstruction, and bleeding after septoplasty. The surgical time for nasal packing was significantly shorter than that for the other 2 suturing methods (P &lt; 0.0001), but there was no statistically significant difference between the two suture methods (P = 0.1358). The Visual Analog Scale scores showed that the pain in the packing group was significantly higher than that in the other 2 groups within 2 days after surgery (P &lt; 0.0001). The pain during suture removal was significantly higher in the packing group than in the “sewing group” (P &lt; 0.0001). The number of injuries to the outer wall of the nasal cavity by continuous suturing was significantly higher than that by sewing (P &lt; 0.0001). Tearing within 2 days after surgery was significantly higher in the packing group than in the other 2 groups (P &lt; 0.0001). Compared with nasal packing, nasal septum suturing can significantly reduce postoperative pain and tearing, improve comfort, and do not increase bleeding. The newly described nasal septum sewing method in this study has no difference in surgical time compared with the traditional suturing method and can reduce injuries to the outer wall of the nasal cavity. In addition, it is painless and easy to remove during suture removal.

Exploring the drivers behind visiting repair cafés: Insights from mental models

Community initiatives play a critical role in fostering a circular economy. Repair cafés, as free community repair events, have been found to be successful in promoting the culture of repair and educating diverse audiences on product durability. However, research on what drives visitors’ participation in such events is scarce. This information is needed to understand how the initiatives can develop and reach more visitors. This study aimed to explore the drivers behind visiting repair cafés using a mental model approach. Thirty visitors to Dutch repair cafés mapped their mental models of the motivational process behind attending the events by drawing influence diagrams and submitted to interviews that provided more in-depth discussions of their mapped mental models. The findings highlight the key drivers of repair café attendance — namely, environmental concerns; profiting from the knowledge, skills and materials available at repair cafés; the desire to demonstrate the importance of repair; and being part of a social movement. Interestingly, meeting others or experimenting with new repair methods were not seen as important drivers of visiting repair cafés. In conclusion, this study complements the earlier repair motivation literature and offers implications for how to promote consumer participation in repair initiatives.

An Underrated Performer in Repair of Rotator Cuff Tears: Single-row Suture Anchor Technique

Abstract Background: Single-row suture anchor technique is a well-established, economical, and relatively easier method of arthroscopic rotator cuff repair that has been recently tripped over by double-row technique which is proven to be biomechanically superior. However, this advantage is not reflected in the functional outcome scores which are reported to be identical with both single- and double-row techniques. Materials and Methods: A prospective cohort study was performed on 67 patients with degenerative rotator cuff tear, diagnosis was confirmed on radiological magnetic resonance imaging, treated surgically by single-row suture anchor method, and evaluated for functional outcome at minimum 1-year follow-up. Pre- and postoperative Visual Analog Scale (VAS) and American Shoulder and Elbow Surgeons (ASES) scores were calculated at initial evaluation and the end of 1-year follow-up. Results: Eighty-six percentage of the patients showed a clinically significant improvement in VAS and ASES scores. Conclusion: Consistent acceptable success rates in terms of outcome functional scores, including patient reported outcomes, depict single-row suture anchor technique as a reliable option for the management of degenerative rotator cuff tears 3 cm or less.
