With recent advances in scanning probe microscopy (SPM), it is now routine to determine the atomic structure of surfaces and molecules while quantifying the local tip-sample interaction potentials.Such quantitative experiments using noncontact frequency modulation atomic force microscopy is based on the accurate measurement PCB of the resonance fre
The headwaters of fluvial systems on the East SUPREME MULTIVIT WITH IRON European Plain between the boundaries of the Marine Isotope Stage 2 (MIS 2) and MIS 6 glaciations evolved during the last 150,000 years.At least three main events of high surface runoff caused intensive erosion: at the end of MIS 6, at the end of MIS 2 and in the Middle Holoce
We measured visual performance in achromatic and chromatic spatial tasks of mercury-exposed subjects and compared the results with norms obtained from healthy individuals of similar age.Data were obtained for a group of 28 mercury-exposed subjects, comprising 20 Amazonian gold miners, 2 inhabitants of Amazonian riverside communities, and 6 laborato
Ricers Health insurance companies are confronted with various tasks in order to offer life-long health care services to their customers.Increasing health expenditures and growing life expectancy necessitates doing annual calculations.At this point triggering factor is applied as a control instrument for continuously seen alteration of health expens
The bowmouth guitarfish (Rhina ancylostomus) is among the most endangered of marine vertebrates, and evidence of severe declines and localized extinctions has been reported.Yet its life history and ecology suffer from a lack of scientific attention due to the scarcity and unpredictable movements of the species.By collecting opportunistic records fr
