Microstructural Effects of Sulphate Attack in Sustainable Grouts for Micropiles

Nowadays, the use of micropiles has undergone a great development. In general, they are made with cement grout, reinforced with steel tubing. In Spain, these grouts are prepared using OPC, although the standards do not forbid the use of other cements, like sustainable ones. Micropiles are in contact with soils and groundwater, in which the presence of sulphates is common. Their deleterious effe...

TSA: Mission Creep Meets Waste

Mass media regularly feeds on the Transportation Security Administration (TSA)’s checkered past, and for good reason. According to a recent ABC News exclusive, “an internal investigation of the Transportation Security Administration revealed security failures at dozens of the nation’s busiest airports, where undercover investigators were able to smuggle mock explosives or banned weapons through...

Alterations in Total Sialic Acid (TSA), Total Proteins (TP) and TSA/TP ratio in cancer patients

Total serum sialic acid (TSA), total proteins (TP) and TSA/TP ratio (as tumor markers) have been estimated in 108 cancer patients, 30 pathological controls and 50 normal healthy controls. Data analysis indicated a significant increase (p< 0.001) in the TSA and TSA/TP ratio in cancer patients (98.41 ± 13.5 mg/dl and 15.31 ± 2.57 mg/gm) as compared to pathological controls (77.57 ± 21.09 mg/dl an...
