Battling the waste sector´s common enemy: moisture content

Moisture content has always been a barrier to maximizing profit from many waste streams. The problematic moisture content is mainly contained in the cell structure of organic materials. Conventional mechanical and thermal dryers like belt, drum, and liquidized bed dryers can’t open the cell structures of organic material and remove the moisture inside. Any dryer with mechanical pulverizing ...

Greenhouse Gas: You can`t manage what you can`t measure

The world is readying itself for greenhouse gas (GHG) regulation coming with the next US administration. Because GHGs have so far not been regulated, the imposition of restrictions on emissions has the potential to drive a fundamental restructuring of our carbon-based economy. If analysts are correct, the “right” to emit GHGs, which today is “free” in the United States, could cost industry up to ...

Oil and water don`t mix

Small spots of motor oil on your driveway look tacky enough. Leaks of hydraulic oil from the hydro turbine of a big pumped-storage plant are not only more noticeable, but they also could end up in the facility's sump or in its reservoir, as well. At the Blenheim-Gilboa Pumped Storage Power Project in New York's Catskill Mountains, there's another reason leaks are unacceptable. The New York Power ...

Using the Terrestrial Residue EXposure (T‐REX) model to assess threatened and endangered bird exposure to and risk from pesticides

The Terrestrial Residue EXposure (T‐REX) model, a spreadsheet‐based model developed by the U.S. Environmental Protection Agency (USEPA), is used to estimate the concentrations of pesticides on some representative avian terrestrial food items following a foliar pesticide application. T‐REX uses 5 or 6 categories of food items to assess exposure for birds. Different body size classes are used to ...

Micro Pulse LiDAR: A Critical Tool for Emissions Source Detection

Micro Pulse LiDAR remote sensing data are used to calculate a highly accurate Planetary Boundary Layer (PBL) height to improve plume models that help assess emissions sources. Poor air quality is a growing health issue that has a negative impact on the quality of life for millions of people. To help alleviate this serious problem, scientists at Bubbleology Research International (BRI) have ...

Dependence of T-lymphocyte activation on the extent of cellular damage

Mechanically damaged cells release intracellular substances, resulting in the activation of CD4- and CD8-positive T-lymphocytes. The goal of this investigation was to quantify and compare fractions of activated CD4- and CD8-positive T-lymphocytes, based on the quantity of damaged cells in a given blood sample. Blood samples were mechanically stressed by vortexing intensely. Subsequently, ...

The principal rapamycin-sensitive p70(s6k) phosphorylation sites, T-229 and T-389, are differentially regulated by rapamycin-insensitive kinase kinases

Mitogen-induced activation of p70(s6k) is associated with the phosphorylation of specific sites which are negatively affected by the immunosuppressant rapamycin, the fungal metabolite wortmannin, and the methylxanthine SQ20006. Recent reports have focused on the role of the amino terminus of the p85(s6k) isoform in mediating kinase activity, with the observation that amino-terminal truncation ...
