Medium induced parton energy loss is not conclusively established neither in very peripheral heavy-ion collisions nor proton-ion collisions. However, the standard interpretation of azimuthal momentum anisotropies theses systems implies some partonic rescattering. The upcoming light-ion runs at LHC provide a unique opportunity to search for different similar size. Here, we make predictions expec...

Lead (II) ion adsorption capacity of clinoptilolite from artificial polluted tap water was investigate in this study. For the experimental studies, Clinoptilolite mineral which is 25-140 mesh size was used by activating with HCl, and lead ion removal efficiencies were examined. Experiments were studied under laboratory batch conditions were run at different pH values, temperatures. The highest ...

There is growing concern about the accumulation of metals in tropical agricultural soils. In this study, experimental results from batch studies were used to test whether multi-surface geochemical models could describe metal binding in selected Vietnamese soils. The multi-surface models considered metal binding to iron hydroxides (using the diffuse layer model), organic matter (Stockholm Humic ...

We have observed a distinct surface phase transition for an important class of colossal magnetoresistive materials, La0.65D0.35MnO3 (with D = Sr, Pb) occurring in a surface layer compositionally different from the bulk. The surface phase transition occurs around 240 K compared to 350 K for the bulk and is fundamentally different. In the bulk, a ferromagnetic metal to paramagnetic ‘bad metal’ oc...

About a 10-15% difference was observed by comparing (CDC) bovine blood to a lead standard addition curve using human blood. Results similar to the mean of the CDC survey were obtained by adding lead directly to the bovine blood using standard addition techniques. These results indicate that standard additions of lead should be made to the same matrix and that matrix effects can occur when blood...

A new 3-D mercury model has been developed within the Danish Arctic Monitoring and Assessment Programme (AMAP). The model is based on the Danish Eulerian Hemi-spheric Model, which in the original version has been used to study the transport of SO 2 , SO 2− 4 and Pb into the Arctic. It was developed for sulphur in 1990 and in 1999 5 also lead was included. For the current study a chemical scheme...

Recent ice core measurements show lead concentrations increasing since 1970, suggesting new nonautomobile-related sources of Pb are becoming important worldwide (1). Developing a full understanding of the major sources of Pb and other metals is critical to controlling these emissions. During the March, 2006 MILAGRO campaign, single particle measurements in Mexico City revealed the frequent appe...
