To create a stable road surface, the road construction techniques are time-consuming and expensive for a traditional construction which requires compaction of soil, aggregate base, sub-base and asphaltic layers. A Geosynthetic Access Mat (GAM) system can serve as an alternative to other traditional construction techniques to accommodate temporary construction. Due to its rigidity, the mat system can provide substantial vertical resistance to the applied load under a large deflection subject to soil conditions. This paper provides details of GAM specifications, soil conditions, applications, installation procedure, comparison with other soil stabilization methods and Aramco experience for deployments of these mats.展开更多
冠突散囊菌(Eurotium cristatum)闭囊壳的产生和数量受各种与有性产孢相关的基因控制,而MAT基因(Mating type gene,MAT)是其中的关键基因之一,为调查MAT基因在冠突散囊菌不同发育阶段的表达量变化,应用实时荧光定量PCR技术对该菌的营养...冠突散囊菌(Eurotium cristatum)闭囊壳的产生和数量受各种与有性产孢相关的基因控制,而MAT基因(Mating type gene,MAT)是其中的关键基因之一,为调查MAT基因在冠突散囊菌不同发育阶段的表达量变化,应用实时荧光定量PCR技术对该菌的营养生长时期、无性产孢时期和有性产孢时期3个阶段的MAT基因表达量进行检测。结果显示:以营养生长时期为对照,在有性产孢时期MAT1-1-1基因上调31.12倍,MAT1-2-1基因上调5.87倍;在无性产孢时期MAT1-1-1基因上调4.25倍,MAT1-2-1基因仅为对照的0.03倍。表明,MAT基因与冠突散囊菌的有性产孢相关,其中MAT1-1-1基因还可能与无性产孢相关。展开更多
