China and Transparency Norm Development in Global Extractives Governance

Growing global demand for extractive resources, such as metals and minerals, particularly to produce low-carbon products, requires international society to develop effective global governance mechanisms to mitigate some of the environmentally and socially negative impacts of mining operations beyond national borders. Since early 2000, several transnational extractive governance initiatives (TEGI)

Volatile organic compound emissions when drying wood particles at high dewpoints

Emission of volatile org. compds. (VOCs) during drying of wood particles for particleboard manuf., or for prodn. of refined biofuels, is a potential environmental problem. The aim of this work is to study the emissions of VOCs during drying, and the influence on the emissions by different drying parameters. The expts. have mainly been done in a batch fluidized bed dryer, but measurements have also

Radiative lifetimes of doubly ionized terbium

Radiative lifetimes of two short-lived levels (i.e. 4f(8) (F-7(6))6p(1/2) (6,1/2)(11/2,13/2)) in Tb II are measured by time-resolved laser-induced fluorescence (LIF) technique with a two-step excitation process. Free Tb III ions are produced in a laser-induced plasma. Lifetime values are evaluated with a deconvolution procedure of the time-resolved fluorescence signal with the temporal shape of se
