The current cement industry has several environmental and social problems, including high greenhouse gas emissions, air pollution, water consumption, the generation of large quantities waste. This matter grown into a significant concern, there is now pressing requirement to substitute conventional binding material in concrete, namely Ordinary Portland Cement (OPC). paper presents report on hybr...

BACKGROUND Atherosclerotic plaque behaviour is influenced by intra-plaque inflammation, matrix turnover, and the lipid core volume. Peroxisome proliferator activated receptor gamma (PPARgamma) modulates atherosclerosis by its anti-inflammatory and anti-protease activity. PPARgamma promotes lipid efflux through the liver X receptor alpha (LXRalpha) and the ATP binding cassette transporter A1 (AB...

On the UK Continental Shelf, up to 80,000 tonnes wet weight of oily drill cuttings are produced annually. These are heterogeneous wastes generated from the petroleum drilling industry, composed of significant percentages of hydrocarbons, heavy metals and chlorides. Since 1992, the discharge of drill cuttings containing more than 1% oil-on-cuttings has been prohibited. Moreover, the extensive in...

Additive Manufacturing (AM) methods in the construction industry typically employ ground-based deposition methods. An alternative to transform role of AM is introduce an aerial capability. A recent project titled Aerial (AAM), first system use untethered, unmanned vehicles (or ‘drones’), has demonstrated 3D-printing cementitious materials during flight. autonomous would minimise requirements fo...

Abstract Literature lacks data on the performance of waste plastics in controlling NOx emissions practical combustors operating typically temperature window 1000–1200 °C, under a range fuel-oxygen equivalence ratios, preventing recycling this application. In contribution, we demonstrate that plastics, particular polyethylene, can serve as reburning fuel for converting nitrogen oxides (NOx) into...

There is an increasing need to identify the effect of mix composition on the rheological properties of composite cement pastes using simple tests to determine the fluidity, the cohesion and other mechanical properties of grouting applications such as compressive strength. This paper reviews statistical models developed using a fractional factorial design which was carried out to model the influ...

This paper presents the strength and leaching performance of stabilized/solidified organic and inorganic contaminated site soil as a function of time and the effectiveness of modified clays applied in this project. Field trials of deep soil mixing application of stabilization/solidification (S/S) were performed at a site in Castleford in 2011. A number of binders and addictives were applied in ...

Grinding coals to a pulverised coal specification for blast furnace injection can be costly, which is why some iron manufacturers choose a larger granulated coal size specification. However, there is a concern that these coals may have lower burnout in the raceway region so there is a technical and economic balance with coal grinding. This paper investigates how the process of grinding alters t...

Non-cytotoxic concentrations (1.5, 3 and 6 microM) of sodium arsenite (SA) were used to study its cytogenetic effects with special reference to the frequency and nature of chromosomal aberrations on the X chromosome at Xq21 and at centromeric regions in CHO9, EM-C11, V79, V-H4 and CHE cell lines using Giemsa and FISH techniques. A high frequency of chromosomal breakpoints was distributed on the...
