Mobile communication, in particular mobile telephony, is a service whose nonexistence nowadays is unimaginable. The ongoing, ever increasing penetration of mobile communication equipment, presently intensified by the transition from second generation1 to t ...
The performance of commonly used pseudopotentials for calcns. of nucleus-independent chem. shifts (NICS) at the center of coinage-metal rings (M4Li2 (D4h), M = Cu, Ag, Au) was studied. The scalar relativity, which has a nonnegligible effect on NICS, is acc ...
In this paper, we apply speaker diarization strategies from a single source to the task of estimating the dominant person in a group meeting. Previous work has shown that speaking length is strongly correlated with perceived dominance. Here we investigate ...
Ruthenium-based anticancer chemotherapies are making significant advances in clinical trials. Until recently, the focus has been on coordination complexes, and mechanisms such as "activation by reduction" and "transferrin-targeted delivery" have been propo ...
We studied the relationships between testate amoeba communities and heavy metal (Pb, Cd, Zn, Ni, Cu, Mn, and Fe) concentrations in the moss Barbula indica sampled at 29 sites in and around the city of Hanoi (Vietnam). Our first approach was to compare the ...
Some plants able to take up heavy metals from contaminated soils offer a possibility to clean up sites contaminated with heavy metals. Plants thus act as a solar driven pump, which can extract and concentrate heavy metals from the environment. Since most o ...
In vitro breeding and somaclonal variation were used as tools to improve the potential of Indian mustard (Brassica juncea L.) to extract and accumulate toxic metals. Calli from B. juncea were cultivated on a modified MS medium supplemented with 10–200 μM C ...
Since most of the metal-hyperaccumulating wild plants only produce very low biomass and many high-yielding crops accumulate only moderate amounts of metals, the current research is mainly focused on overcoming these limitations and the optimization of meta ...
Low energy collisions of atomic ions and cluster ions with rare gas covered metal substrates can lead to strong light emission which is element and size specific. Instead of a direct energy transfer into the electronic system of the cluster the observed em ...
