In this paper, to investigate the impact of environmental loadings on short-term and creep mechanical characteristics different types clayey soil-Geocomposite Drainage Layers (GDL) interfaces, a series rapid loading shear tests were conducted Mercia Mudstone Clay-GDL interfaces Kaolin subjected drying-wetting cycles, thermal cycles elevated temperature, etc, using bespoke temperature stress-con...

Nowadays, fatigue life of engineering components is a major topic. In the literature, extensive works have been reported in order to assess machining-induced surface integrity which known be first-order parameter for resistance. This paper lies framework turning-induced residual stress prediction by presenting an up-dated method based on two-scale approach. Previous aimed at building 3D hybrid ...

UNLABELLED BACKGROUND Historically, acid pretreatment technology for the production of bio-ethanol from corn stover has required severe conditions to overcome biomass recalcitrance. However, the high usage of acid and steam at severe pretreatment conditions hinders the economic feasibility of the ethanol production from biomass. In addition, the amount of acetate and furfural produced during...

In this study, the incorporation of glass fibers in concrete bridge decks has been studied for improving its mechanical properties as well energy absorption capacity and toughness indices. The mix proportion 1:3:2 (cement:sand:aggregate) was selected having water-cement ratio 0.71. For manufacturing fiber reinforced (GFRC), (2-inch) were incorporated at a percentage level 1 %, 2 3 % 4 by weight...

BACKGROUND Many of the practices currently underway to reduce nitrogen, phosphorus, and sediment loads entering the Chesapeake Bay have also been observed to support reduction of disease-causing pathogen loadings. We quantify how implementation of these practices, proposed to meet the nutrient and sediment caps prescribed by the Total Maximum Daily Load (TMDL), could reduce pathogen loadings an...

A key challenge in reducing the burden of lead poisoning is to identify cost-effective interventions that minimize lead-based paint hazards. One-time professional cleaning of lead-contaminated dust and debris was conducted in 37 housing units with deteriorated lead-based paint and dust lead hazards. These study units are a subset of a larger cohort of the nearly 3500 housing units enrolled in t...
