OBJECTIVES To identify plausible mechanisms by which resilience (low mortality rates despite persistent economic adversity) was achieved in some areas in Britain between 1971 and 2001. METHODS Mixed method observational study, combining quantitative analyses of cause- and age group-specific mortality rates, and area sociodemographic and environmental characteristics, with case studies of resi...

Abstract Cold recycling of asphalt is an effective solution to reduce the environmental impacts pavement construction and operation. This approach reduces use scarce resources fossil fuels, prevents spread greenhouse pollutants in air. Despite its benefits, recycled does have drawbacks, some which include nibbling, stripping, less resistance fatigue. The additives can improve mechanical propert...

Pavements are vulnerable to subgrade layer performance because it acts as a foundation. Due to significant increase in truck traffic, pavement engineers are challenged to build more strong and long-lasting pavements. To increase the load-bearing capacity of pavements, subgrade layer is often stabilized with cementitious additives. Thus, an overall characterization of cementitiously stabilized s...

In the current paper, finite element method is employed for numerical simulations and the study of influential parameters on elastic modulus of polymer-matrix nano-composites. Effects of different key parameters including particle elastic modulus, interphase elastic modulus, matrix elastic modulus, interphase thickness and particle volume fraction on total elastic modulus of nano-composite mate...

and resilient mice. (a) Schematic detailing time-course of chronic social defeat, social interaction testing and tissue collection. (b) To identify susceptible and resilient mice, a social interaction ratio (time in interaction zone with social target/time with target absent) was calculated for each mouse based on (c) behavior in the social interaction test 24 hr after CSDS (susceptible ratio <...

in this research, a braiding-pultrusion production line is developed by modifying a conventional textile maypole braiding machine and adding it to a pultrusion line for production of braid-pultruded (bp) composite rods. in order to evaluate the mechanical properties of bp rods and study the effect of some braiding parameters, they were produced with different braid roving linear densities and b...

OBJECTIVES To examine 10-year mortality and hospital use among individuals categorised as resilient and vulnerable to the impact of chronic pain. DESIGN A cohort record linkage study. SETTING Grampian, Scotland. PARTICIPANTS 5858 individuals from the Grampian Pain Cohort, established in 1996, were linked, by probability matching, with national routinely collected datasets. MAIN OUTCOME ...

The use of waste materials has been increasingly conceived as a sustainable alternative to conventional in the road construction industry, concerns have arisen from uncontrolled exploitation natural resources recent years. Re-refined acidic sludge (RAS) obtained material—acidic sludge—is an source for bitumen. This study’s primary purpose is evaluate resistance warm mix asphalt (WMA) mixtures c...
