Air Force interest in performance-based service contracts preceded Dr. Gansler's memorandum. On April 1, 1999, the Air Force issued Air Force Instruction (AFI) 63 - 124, Performance-Based Service Contracts (PBSC), which contains guidance on implementing performance-based practices for purchasing a...

Review Reports Versions Notes Abstract The subgrade layer’s stability considerably influences the long-term performance of pavement systems. This study investigates the influence of lime as a traditional stabiliser and activated carbon with coir fibre (ACF) as waste materials and an environmentally frien...
From previous reports, two-dimensional (2D) SiO2 nanomesh was successfully prepared and supported Ni nanoparticles for CO methanation [10,11]. Versus three-dimensional (3D) MCM-41 Catalysts 2018, 8, 363; doi:10.3390/catal8090363 www.mdpi.com/journal/catalysts Catalysts 2018, 8, 363 2 of 13...
This paper discusses physical measurements of indoor temperature in a case study building at the University of Cambridge and reports findings of a workshop with researchers, building professionals and graduate students working on environmental performance in the built environment. The workshop addressed ...
There have been reports of cracking and settlement in the finish mortar caused by upper load, due to the varying densities of the resilient material and varying shapes of the floor plate (corrugated, embossed, flat, etc.). It has also been reported that the use of a ceramic resilient ...

After adjusting dynamic elastic moduli of control boards to 12% MC (Figure 8c), no significant differences in mean is in line with the literature, which reports that axial dynamic stiffness in timber is typically overestimated 10–20...
However, reports on multi-axial stress performance of SCC, including composite compression-shear stress, are relatively bare. Yu et al. [16] discussed the self-compacting lightweight aggregate concrete under combined compression-shear stress and proposed the damage criteria based on the experimental ...
Therefore, the above reports all indicate that the linear dependence is related to the small size effect of SnO2 materials. However, the detailed reason needs further investigation since the sensing property of SnO2 nanomaterials is not only affected by the small size effect, but also related to ...
