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...

The shape and flow rate of the Air Intake manifolds can make a big difference to fuel mixing and power on the K20. It's not uncommon that air intake manifolds are in dire need of aftermarket tuning parts, although a few makers like Honda actually provide reasonably good air intake manifold...
Review Reports Versions Notes Abstract One of the major challenges in the removal of organic pollutants is to design a material with high efficiency and high flux that can remove both cationic and anionic dyes, oil-in-water (O/W) emulsion and heavy metal ions. Herein, we constructed novel ch...

In recent years, the research trend on water-based lubricants added with nanoparticles (NPs) is continuously ascending due to their excellent tribological properties and promising potential in hot steel rolling, even though the relevant reports are still scarce [8,16–23]. For instance, Bao et ...
These reports showed increased electron mobility between the cerium buffer layer and support, favouring the formation of oxygen vacancies in CeO2. Rangaswamy et al. [19] studied CeO2–Sm2O3 and CeO2–La2O3 catalysts, which could oxidize 50% of diesel soot under loose contact mode at 517 ...
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...
Even though most reports state that anatase performs better than rutile [79,80], recent experimental and theoretical studies have demonstrated that a mixture of anatase and rutile in the right proportions should provide even better photocatalytic activity due to the fact that, in the mixed titania ...
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 ...
