The nuclear equation of state (EOS) is probed from statistical parameters, determined in an excitation function experiment on p + Xe-nat reactions at 200-1400 MeV. Total charge (Z) distributions follow a cascade-[multi]fragmentation-evaporation (CFEM) model well. The caloric curve in regions supposedly dominated by fast processes is compatible with a pure statistical multifragmentation (SMM) proce
We have used the Monte Carlo technique to investigate the mechanism of scattering-assisted charge transport in semiconductor superlattices under a strong applied electric field in the Wannier-Stark (WS) regime. The distribution function of quasi-two-dimensional carriers localized in each WS level is calculated, and the contributions of different scattering mechanisms to the total scattering probab
The inner mitochondrial membrane is selectively permeable, which limits the transport of solutes and metabolites across the membrane. This constitutes a problem when intramitochondrial enzymes are studied. The channel-forming antibiotic AlaM (alamethicin) was used as a potentially less invasive method to permearbilize mitochondria and study the highly branched electron-transport chain in potato tu
Change is sweeping through the world of museums, technologically, financially, and ideologically, impacting on the sociocultural evolution of their roles and status. We seek to contribute to ongoing reflections by offering a conceptual framework that links museums with democratic theory, to citizenship and its practices – a domain that is also in notable transition. We connect concretely with the
To talk about the internet as a civic space requires some preliminary conceptualization; thus, first I briefly discuss two models of democracy – elitist and republican – to show that the ideals of civic participation can vary considerably. This is illuminated by a discussion of the role of the net in electoral and alternative politics. From there I approach civic space through two key concepts: ci
