Structural similarities of some secondary lead minerals

Some structural analogies found in tsumebite, vauquelinite, forns.cite, and brackebuschite make it possible to place these secondary lead minerMs in the s~me series with general formula Pb~MeII(Z)(XQ)(Y04), where MelI is a bivalent cation as Cu 2+ or Mn 2+, Z is the hydroxyl group or the w~ter molecule, X is S, Cr, or V, ~nd Y is P, As, or V. Some crystallochemical considerations are developed ...

Morphology Change and Structural ‎Evaluation of Carbon Nanostructures

   In this study, the change of porosity and roughness of carbon nanostructures, including fullerenes, carbon nanotubes and graphene was investigated according to oxidation process. The effect of oxidation was more sensible on smoother surface of nanostructures. Oxidation increases surface roughness of graphene up to 5.2% and porosity up to 35.2%. While, roughness of hummers graphene is 13....

Forecasting under structural change

Forecasting strategies that are robust to structural breaks have earned renewed attention in the literature. They are built on weighted averages downweighting past information and include forecasting with rolling window, exponential smoothing or exponentially weighted moving average and forecast pooling. These simple strategies are particularly attractive because they are easy to implement, pos...

Aging and Structural Change

Many studies analyzed in depth how aging affects aggregate economic performance. But analyses of these effects on the employment structure are scarce and they do not consider that consumption patterns, the supply of goods and services, and also sectoral labor productivity are all likely to adjust to aging and will change. Hence, regression analysis of sectoral employment shares is proposed that...
