新型高粘改性剂改性OGFC混合料性能研究

广东建材 2024年第4期40卷 7-10页

作者：林也坚漳州城投建工集团有限公司

本文研究了一种新型的开级配沥青磨耗层(OGFC)改性剂ats,并通过实验测试了其改性效果。由于OGFC的孔隙率较大,易受外界环境的影响,因此要求采用的沥青具有耐久的握裹力、较强的粘着力及抗老化性能。本文在水稳定性、低温性能及动稳定度... 详细信息

本文研究了一种新型的开级配沥青磨耗层(OGFC)改性剂ats,并通过实验测试了其改性效果。由于OGFC的孔隙率较大,易受外界环境的影响,因此要求采用的沥青具有耐久的握裹力、较强的粘着力及抗老化性能。本文在水稳定性、低温性能及动稳定度等方面对ats进行了研究,并与传统改性剂TPS进行了对比。实验结果表明,通过ats进行改性的OGFC混合料在各项性能表现上均优于TPS,具有更好的耐久性和稳定性,表明ats是一种具有潜力的OGFC改性剂。

Purpose: The purpose of this study was to determine whether practicing athletic trainers(ats) were using the stepwise progression to make return-to-play(RTP) decisions after concussion and to determine what factors influenced their decision to use the stepwise progression.Methods: A total of 166 ats(response rate = 16.6%) completed a 21-item questionnaire that evaluated participant demographics, methods of concussion management, and RTP decision-making using the stepwise progression. Descriptive statistics and a logistic regression were completed to analyze data.Results: Factors such as education level(p = 0.05) and number of concussions treated(p = 0.05) predicted use of the stepwise progression,whereas sex(p = 0.17), employment setting(p = 0.17), state law(p = 0.86), and years practicing(p = 0.17) did not predict whether ats were following the stepwise progression.Conclusion: The majority of the ats from this study are employing the stepwise progression to safely return athletes to play after sustaining a concussion. This demonstrates that ats are providing a standard of care for concussed athletes across various athletic training settings; however,having a graduate degree and treating more concussions per year are predictors of whether an AT follows all steps of the stepwise progression.

The complete genome of methanol-utilizing Amycolatopsis methanolica strain 239T was generated,revealing a single 7,237,391 nucleotide circular chromosome with 7074 annotated protein-coding sequences(CDSs).Comparative analyses against the complete genome sequences of Amycolatopsis japonica strain MG417-CF17T,Amycolatopsis mediterranei strain U32 and Amycolatopsis orientalis strain HCCB10007 revealed a broad spectrum of genomic structures,including various genome sizes,core/quasi-core/non-core configurations and different kinds of episomes.Although polyketide synthase gene clusters were absent from the A.methanolica genome,12 gene clusters related to the biosynthesis of other specialized(secondary)metabolites were identified.Complete pathways attributable to the facultative methylotrophic physiology of A.methanolica strain 239T,including both the mdo/mscR encoded methanol oxidation and the hps/hpi encoded formaldehyde assimilation via the ribulose monophosphate cycle,were identified together with evidence that the latter might be the result of horizontal gene transfer.Phylogenetic analyses based on 16S rDNA or orthologues of AMETH_3452,a novel actinobacterial class-specific conserved gene against 62 or 18 Amycolatopsis type strains,respectively,revealed three major phyletic lineages,namely the mesophilic or moderately thermophilic A.orientalis subclade(AOS),the mesophilic Amycolatopsis taiwanensis subclade(ats)and the thermophilic A.methanolica subclade(AMS).The distinct growth temperatures of members of the subclades correlated with corresponding genetic variations in their encoded compatible solutes.This study shows the value of integrating conventional taxonomic with whole genome sequence data.

Discerning electromagnetically induced transparency(EIT) from Autler–Townes splitting(ats) is a significant issue in quantum optics and has attracted wide attention in various three-level configurations. Here we present a detailed study of EIT and ats in a five-level atomic system considered to be composed of a four-level Y-type subsystem and a three-level Λ-type subsystem. In our theoretical calculations with standard density matrix formalism and steadystate approximation, we obtain the general analytical expression of the first-order matrix element responsible for the probe-field absorption. In light of the well-known three-level EIT and ats criteria, we numerically show an intersection of EIT with ats for the Y-type subsystem. Furthermore, we show that an EIT dip is sandwiched between two ats dips(i.e., multi-dip mixture of EIT and ats) in the absorption line for the five-level system, which can be explained by the dressed-state theory and Fano interference.

随着电子设备更加精密和复杂,ats逐渐暴露出通用性差的问题。业界产生了面向信号的测试,并提出相关标准,以实现通用化。该测试方法在信号和虚拟资源描述方面的标准较为成熟,但在实际中还需要完成虚实映射等工作。针对该问题,提出一种面向信号的ats运行时系统方案,以ATML标准为基础,设计具备初始化通道、信号能力匹配和路径择优与处理功能的运行时系统,完成虚拟资源到物理仪器的虚实映射,对该方案进行仿真验证,其匹配结果以及通道输出符合预期。对于ats的开发与使用而言,在减少专用设备、实现通用化、易于开发维护等方面均有着重要意义。
