Conductive hydrogel-based wearable strain sensors with tough, stretchable, self-recoverable, and highly sensitive properties are demanded for applications in electronic skin human–machine interface. However, currently, put forward higher requirements on their biocompatibility, mechanical strength, sensitivity. Herein, we report a poly(vinyl alcohol)/phytic acid/amino-polyhedral oligomeric silsesquioxane (PVA/PA/NH2-POSS) conductive composite hydrogel prepared via facile freeze–thaw cycle...
Underground reservoirs in coal mines, consisting of goafs (By goaf, we mean the space that remains underground after extraction valuable minerals), are commonly utilized for mine water storage and drainage, with their primary load-bearing structures being “roof–coal pillar” systems. Consequently, this structure must endure repeated immersion behavior resulting from fluctuations level, risk geological disasters. This paper analyzes variation mechanical properties sandstone–coal composite...
Nine blasts with cylindrical granite specimens were carried out under different stemming conditions. All rock had a diameter of 240 mm and length 300 mm. Explosive Pentaerythritol tetranitrate (PETN) specific charges 0.2 0.3 kg/m3 used, the in large explosion chamber. Each specimen was enclosed by steel box chamber during blasting, without constraint or confinement to from lateral top sides. During blasting high-speed camera used film process monitor gas ejection. After each blast all...
Abstract Rolls are prone to surface wear, fracture, and other defects during operation. To investigate the enhanced performance of 9Cr5Mo roll steel, integrity microstructure steel following warm shot peening were analyzed under varying quenching parameters. The results showed that with increasing temperature, hardness specimen residual stress first increased then decreased, roughness decreased increased. stresses specimens greater was smaller when quenched at 1030°C. It found due producing...
Green manufacturing technology is a key pathway for achieving sustainable development in modern particularly the precision machining of automotive components. This study provides comprehensive overview core elements green manufacturing, focusing on four aspects: material selection, energy efficiency optimization, waste minimization, and recycling remanufacturing. The review also examines application advanced technologies, such as laser digital twins, process, highlighting their effectiveness...
Based on the data of global mineral production and ore recovery in mining processing, this paper presents annual 25 minerals calculates losses 20 from year 1920 to 2018. The results indicate that 23 has increased by between 1 930 times since 1920, similar increase GDP per capita 1960. At same time, a vast amount been lost processing 1920. Hence, discusses possibility increasing ratio.
Purpose To quantitatively evaluate the cartilage alteration of talus for chronic lateral ankle instability (LAI) with isolated anterior talofibular ligament (ATFL) tear and combined ATFL calcaneofibular (CFL) using T 2 ‐mapping at 3.0T. Materials Methods In all, 27 patients including 17 10 ATFL+CFL tear, 21 healthy subjects were recruited. All participants underwent scan 3T completed American Orthopaedic Foot Ankle Society (AOFAS) scoring. The total talar (TTC) was segmented into six...
The experimental investigation of the dynamic mechanical behavior graphene aerogel is still lacking due to its low impendence. present work, therefore, reports on preliminary characterization energy absorption characteristics by using split Hopkinson pressure bar emphasis influence drying method. aerogels were synthesized sol-gel method and dried, either supercritical CO2 (SD) or freeze-drying methods (FD). It was observed that under uniaxial compression, SD samples exhibited a negative...
Abstract Crack velocity, gas ejection, and stress waves play an important role in determining delay time, designing a blast understanding the mechanism of rock fragmentation by blasting. In this paper, emerging times earliest cracks ejection on lateral surfaces cylindrical granite specimens with diameter 240 mm length 300 were determined high-speed photography, strain measured instrument dynamic measurement during model The results showed that: (1) velocity penetration into radial was range...
Abstract A new CTOD calculation method is investigated in this study, considering the FPZ and effective Young’s modulus. The calculated values from four theoretical models are compared with measured three-point beam experiments, differences between them analyzed. consists of two parts: (1) displacement generated by elastic–plastic deformation crack tip region, (2) micro-damage FPZ. value caused accounts for 81–92% overall CTOD. Thus, modulus introduced to modify calculating result indicates...
To quantitatively assess changes in cartilage matrix after acute anterior cruciate ligament (ACL) rupture using T2- and T2⁎-mapping analyze the correlation between results of both methods.Twenty-three patients 23 healthy controls were enrolled underwent quantitative MRI examination. The knee was segmented into six compartments, including lateral femur (LF), tibia (LT), medial (MF), (MT), trochlea (Tr), patella (Pa). T2 T2⁎ values measured full-thickness as well superficial deep layers each...
Background: Rotator cuff tears with shoulder stiffness remain a difficult issue. Despite the reported satisfactory results of 1-stage surgery, little information is available regarding factors that affect clinical outcomes. Purpose/Hypothesis: To evaluate arthroscopic treatment rotator and to present influence duration symptoms (DOS) on postoperative functional The hypothesis was long preoperative DOS related worse Hypothesis: A Study Design: Cohort study; Level evidence, 2. Methods: cohort...
Background: Most patients return successfully to shoulder involving sports or activity after rotator cuff repairs. It has not been decided yet whether postoperative participation in adds the risk of retear. Purpose/Hypothesis: The purpose was verify who participate activities repair have a higher structural failure than nonactive and investigate relationship between function tendon integrity active patients. hypotheses were that (1) retear rate (2) is associated with worse functional...
The construction of the relation between critical energy release rate, GIc, and mode I fracture toughness, KIc, is great significance for understanding mechanism facilitating its application in engineering. In this study, experiments using NSCB CCCD specimens were conducted. effects specimen sizes, loading rate lithology on GIc KIc studied. was calculated by integrating load-displacement curve according to Irwin's approach. Based measured rock specimens, a found be different from classical...
Abstract In this study, the application of characteristic impedance in estimating specific energy and average fragment size rocks was investigated during rock breakage at high strain rates. To achieve this, specimen prepared accordance with recommendations International Society for Rock Mechanics broken rates using split Hopkinson’s pressure bar system. Results reveal that although rate is well related to rocks, product more reliable forementioned parameters. addition, dissipated generally...
Schwannomas (neurilemmomas) are benign nerve sheath tumor originating from Schwann cells. They well circumscribed and rarely infiltrate metastasize. of the head neck commonly occur in tongue followed by palate, floor mouth, buccal mucosa, mandible. Tongue base schwannomas could extend to pharyngeal cavity or mouse, it is difficult differentiate between tumors lingual, hypoglossal, glossopharyngeal nerves. Surgical treatment because limited operative exposure. Although mandibulotomy with lip...
