The impact of UV radiation on the high-temperature behavior of polyphenylene sulfide (PPS) fiber was investigated in this study.The ultimate strength, failure strain elasticity modulus and toughness were employed to evaluate the degradation caused by the coupling effects of UV radiation and high temperature.The degradation characteristics of PPS fi

Expansions and collapses of a vapor bubble at the pressure antinode of a standing acoustic wave in liquid acetone at temperatures 273 K and 293 K were compared.In the first case, the acoustic excitation amplitude and frequency were 15 bar and 19.3 kHz, whereas in Bioflavonoids the second case they were varied on the condition that the maximum radiu

In this study, we identify a novel two-component system in Acinetobacter baumannii (herein named AmsSR for regulator of alternative metabolic systems) only present in select gammaproteobacterial and betaproteobacterial species.Bioinformatic analysis revealed that the histidine kinase, AmsS, contains 14 predicted N-terminal transmembrane domains and

Programmed SKIN CARE death-1 (PD-1), an immunoinhibitory receptor on T cells, is known to be involved in immune evasion through its binding to PD-ligand 1 (PD-L1) in many chronic diseases.We previously found that PD-L1 expression was upregulated in cattle infected with bovine leukemia virus (BLV) and that an antibody that blocked the PD-1/PD-L1 int

This paper presents the results of research on transverse shrinkage of welded butt joints conducted according to the principles of experimental design and under production conditions for two main welding techniques used in shipbuilding (FCAW and SAW).Analysis took into account the technological and structural parameters influencing the assembly sui
