This study investigates an internal erosion site along the Crawford County Levee System in Arkansas, USA using electrical resistivity tomography (ERT) lines, complemented by multichannel analysis of surface waves (MASW) and capacitively coupled resistivity (CCR) surveys. The goal of the testing was to identify internal erosion areas and establish “best recommend practices” for future investigations of internal erosion. For the...

Biological waste degradation is the main driving factor for landfill emissions. In a 2-year laboratory experiment simulating different landfill in-situ aeration scenarios, the microbial degradation of solid waste under different oxygen conditions (treatments) was investigated. Nine landfill simulation reactors were operated in triplicates under three distinct treatments. Three were kept anaerobic, three were aerated for 706 da...

Summary When resources are limited, the hypocrealean fungus Trichoderma guizhouense can overgrow another hypocrealean fungus Fusarium oxysporum , cause sporadic cell death and arrest growth. A transcriptomic analysis of this interaction shows that T. guizhouense undergoes a succession of metabolic stresses while F. oxysporum responded relatively neutrally but used the constitutive expression of several toxin‐encoding genes as...

Summary T richoderma guizhouense NJAU 4742 ( Harzianum clade) can suppress the causative agent of banana wild disease F usarium oxysporum f. sp. cubense 4 (Foc4). To identify genes involved in this trait, we used T ‐ DNA insertional mutagenesis and isolated one mutant that was unable to overgrow Foc4 and had reduced antifungal ability. Using the high‐efficiency thermal asymmetric interlaced‐ PCR , the T ‐ DNA was located in th...
