The necessity to reduce the weight of transport structures, such as cars and airplanes, has become more important due to gas emission regulations. In this regard, the use of hybrid structures made of steel and aluminum i...

Abstract Currently, conventional single-sided friction stir welding is primarily suitable for joining thin plate aluminum alloys, and its application to thick plates is still challenging in terms of welding efficiency an...

With the continuous improvement of lightweight requirements for equipment, Mg alloys are increasingly widely used, and their joining with traditional steel materials is essential. However, Mg and Fe have almost no solid ...

As the water pressure of shield tunnel increases, the key to tunnel construction is to strengthen the water resistance of joints. By analyzing the characteristics of stress and deformation of the gaskets in the joints of...

Abstract Penetration and non-penetration lap laser welding is the joining method for assembling side facade panels of railway passenger cars, while their fatigue performances and the difference between them are not compl...

Concrete-filled steel tubular (CFST) truss arch bridges are widely used in long-span bridge construction due to their high strength, good stiffness, and excellent durability. However, arch rib joints, as critical load-be...

The present study focused on the evaluation of critical influencing parameters of the FSW of AA6061-T6 and AA2024-T351 alloys. The materials properties of AA6061-T6 are heat-treatable alloys possessing properties of good...

Abstract 6082-T6 aluminum alloy is a commonly used aluminum alloy material in the field of rail transit because of its good molding properties, high mechanical properties, excellent corrosion resistance and weldability. ...

Butt welding between SLM-formed AlSi10Mg and rolled 6061 alloy (T6 state) was conducted by the tungsten inert-gas arc welding(TIG) method. The microstructure and mechanical properties of TIG welded joints under different...

A study on the microstructure, mechanical properties, and heat treatment process of pure tantalum TIG joints was conducted. Industrial computed tomography (CT), OM, and SEM were used to characterize the microstructure of...

In the present study, 22 hip joints of Whippet (four), Rottweiler (five) and Labrador Retriever (two) young dogs were evaluated with the aim of comparing the ultrasonic examination of coxofemoral joints with the radiogra...

In modern construction, steel trusses remain one of the most common types of load-bearing structures used in the construction of industrial, civil, and public buildings. Their use is driven by high load-carrying capacity...

Abstract Friction Stir Welding (FSW) is the most promising solid-state metals joining method introduced in this era. Compared to the conventional fusion welding methods, this FSW can produce joints with higher mechanical...

Abstract Devices with variable stiffness are drawing more and more attention with the growing interests of human-robot interaction, wearable robotics, rehabilitation robotics, etc. In this paper, the authors report on th...

Abstract Objectives To develop and evaluate a deep learning model for diagnosing untreated rheumatoid arthritis (RA) using digital camera images of bilateral dorsal hands, benchmarking its performance against the widely-...

Wegener’s Granulomatosis is a multisystemic granulomatous inflammation of small vessels that typically effects the kidney, skin, joints and lower and upper airway tracts. Because of the multisystemic involvement, the s...

Abstract Due to the different microstructures caused by the heat source effect, welding joints exhibit significant differences in mechanical properties compared to the base material. Precise characterization of the const...

OBJECTIVE: Patients with malignancies may develop autoimmune and rheumatic manifestations as a result of generation of autoantibodies, paraneoplastic syndromes, direct invasion of joints and muscles by the tumour cells, ...

La Formación Chenque (Mioceno Inferior-Medio) en la cuenca del Golfo San Jorge representa los depósitos de un evento transgresivo atlántico con evidencias mesoscópicas de tectónica extensional. Se presentan los resu...

Abstract In order to assess the pain phenomenon, a pilot cross-sectional study was conducted. The aim of this study was to determine the correlation between segmental body composition and cervical spine mobility in indiv...

During tunnel construction using the drilling and blasting method, layered jointed rock masses often pose engineering challenges such as over- and under-excavation of the crown and working face. The authors addressed the...

Abstract Non-penetration laser welding of lap joints in austenitic stainless steel sheets is commonly preferred in fields where the surface quality is of utmost importance. However, the application of non-penetration wel...

The calcified chondroid mesenchymal neoplasm (CCMN) was first recognized as a distinct pathologic entity in 2021 at the University of Washington, and fewer than 100 cases of CCMN have been described in the literature. Th...

The case study of closely spaced twin tunnels excavated vertically beneath the adjacent Chaoyangmen station in Beijing, China is introduced. The existing subway station is part of the Beijing subway Line 2. The new recta...
