The study of external renderings in the scope of conservation and restoration has acquired in the last years great methodological, scientific and technical advances.These renderings are important elements of the built structure, for besides possessing a protection function, they possess often a decorative function of great relevance for the image o
Cyclic or fluctuating populations experience regular periods of low population density.Genetic bottlenecks during these periods could give rise to temporal or spatial genetic differentiation of populations.High levels of movement among increasing populations, however, could ameliorate any differences and could also synchronize the dynamics of geogr
At least 150 human proteins are glycosylphosphatidylinositol-anchored Art by Era proteins (GPI-APs).The protein moiety of GPI-APs lacking transmembrane domains is anchored to the plasma membrane with GPI covalently attached to the C-terminus.The GPI consists of the conserved core glycan, phosphatidylinositol and glycan side chains.The entire GPI-AP
