Traffic barriers are in widespread all around the USA as safety countermeasures for reducing the severity of run-off-road crashes. The effect of traffic barriers’ dimension had been ignored in past real-world crash studies due to the considerable cost and time needed for collecting field data. This paper presented two new analytical models to investigate the effect of different variables on the severity of crashes involving traffic barriers, and end treatments. For this reason, a field survey was conducted on over 1.3 million linear feet of traffic barriers (approximately 4,176 miles road) in Wyoming to measure traffic barriers’ geometric features like height, length, offset, and slope rate. The collected data included 55% of all non-interstate roads of Wyoming. Based on results, the crashes involving box beam barriers were less severe than the crashes involved with W-beam or concrete barriers. The traffic barriers with a height between 28 and 31 in. were found safer than the traffic barriers shorter than 28 in., while there was no significant difference between the traffic barriers taller than 31 in. to those shorter than 28 in. in terms of crash severity. The end treatments located nearer to the traffic lane had lower crash severity. 展开更多

Background Damage to the central nervous system(CNS)usually leads to the activation of astrocytes,followed by glial scar formation.For years,glial scar has been thought as a major obstacle for successful axon regeneration.However,increasing evidence suggests a beneficial role for this scar tissue as part of the endogenous local immune regulation and repair process.Surprisingly,in contrast to scars in other tissues,glial scars(mainly consist of reactive astrocytes)in both rat cortex and spinal cord were recently found to be significantly softer than healthy CNS tissues.Naive astrocytes have been found to change their phenotype to reactive astrocytes and gradually into scar-forming astrocytes,upregulating the astrocyte marker glial fibrillary acidic protein(GFAP),vimentin,and inflammatory proteins in almost all known brain disorders.Such phenotype transformation process has been widely thought unidirectional or irreversible.However,recent research revealed the environment-dependent plasticity of astrocyte phenotypes,with reactive astrocytes could revert in retrograde to naive astrocytes in proper microenvironment.In consideration of the important roles of mechanical cues in CNS and the unique softening behavior of glial scars,it is of great interesting to study the effects of dynamic changes of matrix stiffness on astrocyte phenotypic switch.Materials&methods Primary astrocyes were isolated from the cortex of SpragueDawley(SD)rats at PI.After cultured for 2 weeks,astrocytes were encapsulated into a set of three-dimensional(3D)hybrid hydrogel system composed of type I collagen and alginate.Immunofluorescence and Western blot expression analysis were applied for characterizting cell responses to different and dynamically changed matrix stiffness.A molecular dynamics model was developed for simulation.Results&discussion In this work,we established an in-vitro model to study the effects of dynamic changes of matrix stiffness on astrocyte phenotypic switchings in 3D.To simulate native cellular environment,we fabricated 展开更多

Based on 10 shale samples collected from 4 wells in Qinshui Basin,we investigate the full-sized pore structure and fractal characteristics of Marine-Continental transitional shale by performing organic geochemistry,mineralogical composition,Nitrogen gas adsorption(N2 adsorption)and Nuclear Magnetic Resonance(NMR)measurements and fractal analysis.Results show that the TOC content of the shale samples is relatively high,with an average value of 2.44wt%,and the thermal evolution is during the mature-over mature stage.The NMR T2 spectrum can be used to characterize the fullsized pore structure characteristics of shale.By combining N2 adsorption pore structure parameters and NMR T2 spectrums,the surface relaxivity of samples are calculated to be between 1.7877 um/s and 5.2272 um/s.On this basis,the T2 spectrums are converted to full-sized pore volume and surface area distribution curves.The statistics show that the pore volume is mainly provided by mesopore,followed by micropore,and the average percentages are 65.04%and 30.83%respectively;the surface area is mainly provided by micropore,followed by mesopore,and the average percentages are 60.8004%and 39.137%respectively;macropore contributes little to pore volume and surface area.The pore structure characteristics of shale have no relationship with TOC,but strong relationships with clay minerals content.NMR fractal dimensions Dmicro and Dmeso have strong positive relationships with the N2 adsorption fractal dimensions D1 and D2 respectively,indicating that Dmicro can be used to characterize the fractal characteristics of pore surface,and Dmeso can be used to characterize the fractal characteristics of pore structure.The shale surface relaxivity is controlled by multiple factors.The increasing of clay mineral content,pore surface area,pore surface fractal dimension and the decreasing of average pore size,will all lead to the decreasing of shale surface relaxivity. 展开更多

Since the 18th CPC National Congress,the Party Central Committee with General Secretary Xi Jinping as the core has been committed to the construction of ecological civilization,scientific and in-depth understanding of the law of human and economic and social development,creatively proposed a series of new strategies,and has formed a comprehensive and systematic Xi Jinping’s ecological view.The basic connotation is:adhering to the ecological economic view of green development,focusing on the domestic and international ecological political view,constructing an ecological cultural view in harmony between man and nature,and an ecological social view unifying environmental protection and people’s happinesses.Xi Jinping’s ecological view is the inheritance and development of Marxist ecological theory,the enrichment and perfection of theoretical system of socialism with Chinese characteristics (SCC),the new understanding of the laws governing the development of human civilization,the important content for the Chinese dream,and an action to build a beautiful China,thus contributing Chinese wisdom to global ecological governance. 展开更多

VII Conclusion Our British secondary school learners reported significantly higher levels of FLE than FLCA,with a weak negative relationship between both.It confirms the observation that FLE does not represent the positive pole of some generic emotion dimension with anxiety at the negative pole.FLE and FLCA are independent emotion dimensions with a very small amount of overlap.This means that students could score high,or low,on both dimensions.The pedagogical implication is that teachers’attempts to reduce FLCA will not automatically boost student’FLE. 展开更多
