Each year, more than 25 percent of highway fatalities in the United States occur at or near horizontal curves, according to the Federal Highway Administration (FHWA). In an attempt to save lives and prevent injuries, some 30 states across the U.S. are applying high friction surfaces (HFS) to improve skid resistance at locations with a high incident of vehicle crashes such as severe horizontal c...

Lithium is one of the secondary mineral elements occurring in bauxite. The behavior lithium-bearing bauxite digestion process was investigated, and effect conditions on extraction rates lithium studied. results demonstrate that mass ratio added CaO to bauxite, KOH concentration, temperature had a significant efficiency. An L9(34) orthogonal experiment demonstrated order each factor for from pri...

The versatility of FTIR spectrometry was explored by considering a variety of samples drawn from industrial applications, materials science and biomedical research. These samples included polymeric insulators, bauxite ore, clay, human hair and human skin. A range of sampling techniques suitable for these samples is discussed, in particular FTIR microscopy, FTIR emission spectroscopy, attenuated...

Abstract Sending microwaves through bauxite ore allows almost continuous measurement of moisture content during offload by conveyor belt from a ship. Data and results microwave analyser were brought to European Study Group with Industry at the University Limerick, over-arching question whether are accurate enough. The equipment uses linear regression against phase shifts signal attenuation infe...

Inorganic turbidity can limit light penetration in water and reduce phytoplankton photosynthesis. Anthropogenic activities such as mining produce or augment the amount of suspended inorganic particles water. Recent disasters Brazil have released tons mine tailings into aquatic ecosystems, with known unknown negative consequences for life, biodiversity, ecosystem services beyond human material l...

nitrogen oxides and carbon monoxide gases together with dust are known as the major pollutants arising during the blasting operations using the ammonium nitrate-fuel oil (anfo) explosive at the sungun surface mine, located in the northwest of iran. the pollutants were monitored during some blasting operations at the mine. it was concluded that the gases and dust clouds initially went up to the ...

Bauxite formation is usually possible in humid and tropical weather conditions with the enrichment of minerals containing Al2O3 environment. These are found chemical compositions that rich major trace elements, REEs. Karst-type bauxites have different characteristics terms REE elements since they undergo alteration processes. Various correlations can be evaluated using geostatistical methods to...
