Many manufactured articles are made of composite materials often bonded by a phenolic resin.Through a D-optimal design, we optimized a Watch Accessory method to characterize phenolic resins after the extraction process by GC-MS analysis.The study was conducted on three different phenolic resins and four manufactured articles with the same inorganic
Evaluating the energy performance of existing buildings is critical for improving the efficiency and resilience of the building stock as a Oral Pain whole.The importance of this information holds at different scales, both locally and at the national and international levels.A major problem arises from the difficulty in obtaining information from ex
Due to the built-in axle box suspension, the EMU bogie with an inner axle box causes an obvious decrease in the anti-roll stiffness of the carbody and accordingly affects the running performance.The inner axle box bogie is usually accompanied with the measures of installing anti-rolling torsion bars and increasing the vertical stiffness of primary
Abstract Numerous vaccine candidates against SARS-CoV-2, the causative agent of the COVID-19 pandemic, are under development.The majority of vaccine candidates to date are designed to induce immune responses against the viral spike (S) protein, although different forms of S antigen have been incorporated.To evaluate the yield and immunogenicity of
