The fossil record of amphisbaenians in Europe has recently been augmented through the description of new finds across the continent. It has been suggested that the post- Miocene range of amphisbaenians followed a progressive southward constriction that ultimately lead to their extant disjunct distribution. We herein describe amphisbaenian vertebral material from the Pliocene of northern...

The fossil record of Chamaeleonidae is very scarce and any new specimen is therefore considered important for our understanding of the evolutionary and biogeographic history of the group. New specimens from the early Miocene of Aliveri (Evia Island), Greece constitute the only fossils of these lizards from southeastern Europe. Skull roofing material is tentatively attributed to the Czech species...

The productive efficiency of a firm can be decomposed into two parts, one persistent and one transient. So far, most of the cost efficiency studies estimated frontier models that provide either the transient or the persistent part of productive efficiency. This distinction seems to be appealing also for regulators. During the last decades, public utilities such as water and electricity have...

Endogenous quaternary ammonium compounds are involved in various physiological processes in the central nervous system. In the present study, eleven quaternary ammonium compounds, including acetylcholine, choline, carnitine, acetylcarnitine and seven other acylcarnitines of low polarity, were analyzed from brain extracts using a two dimension capillary liquid chromatography–Fourier transform...

We present a neutron-scattering investigation of the crystal structure formed by pH-sensitive poly(2-vinylpyridine) microgel particles with 5 wt % of cross-linker. We focus on highly swollen particles and explore concentrations ranging from below close packing to well above close packing, where the particles are forced to shrink and/or interpenetrate. The crystal structure is found to be random...
