Trump victory: Slap in the face for big data or desperate cry for more?
Stats are the lifeblood of everything, we’re told. Analytics are the new creed, we’re all meant to believe in (and even semi-worship). But overwhelming evidence shows they’re not always that trustworthy. And the fundamental kicker might have come this morning when all those big data predictions on the US election proved so dramatically wrong. Trump didn’t just edge past ...

Water Resources in a Low- to No-Snow Future
Researchers predict a less snowy future in which water reuse can make every drop of available water count Mountain snowpacks provide vital water storage for downstream communities, ecosystems, agriculture, and industry. They release water gradually into the summer, when demand is high and precipitation is low. The warming climate, however, is shrinking mountain snowpacks globally, and climate ...

Soil fertilization with wastewater biosolids – monitoring changes in the ‘soil–fertilizer–plant’ system and phosphorus recovery options
The aim of this study is to establish changes that may occur after a prolonged application of wastewater sludge treated to biosolids, in the ‘soil–fertilizer–plant’ system. Thirteen experimental plots with different soil types planted with experimental crops were investigated in order to evaluate the suitability of these biosolids as soil conditioners and fertilizers. The biosolids were ...

Model 5100 Verification/Validation case study
Background Many sensors used in gas analyzer systems come into direct contact with the process gas, and there is the potential for degradation over time especially with streams that contain contaminants like glycol, moderate to high levels of hydrogen sulfide etc. With sensor degradation, the analyzer response characteristics change resulting in inaccurate readings. In order to address this ...

Lead (Pb) in Workplace Air by Niton 700 Series Field Portable X-Ray Fluorescence (XRF) Analyzer
Procedure: Air samples are collected by drawing workplace air, using personal sampling pumps, through 37-mm mixed cellulose ester (MCE) filters mounted in polystyrene cassettes. Samples are prepared for XRF analyses by transferring each filter, along with the support pad, to a special air filter sample holder, specifically designed for a Niton XRF analyzer. Three separate 60-second readings are ...

Lead in Paint and Soil in Karnataka and Gujarat, India
Blood lead surveys in several areas of India have found very high percentages of children with elevated blood lead levels. Fifty-three percent of children under 12 years of age in a sevencity screening had blood lead levels equal to or greater than 10 μg/dL, the level currently considered elevated by the U.S. Centers for Disease Control and Prevention (CDC). A number of these surveys ...
