TRENDS AND DETERMINANTS OF POST-INTEGRATION AGRICULTURAL TRANSFORMATION IN POLAND AND BULGARIA


ERK1/2 signalling dynamics promote neural differentiation by regulating chromatin accessibility and the polycomb repressive complex.

Fibroblast growth factor (FGF) is a neural inducer in many vertebrate embryos, but how it regulates chromatin organization to coordinate the activation of neural genes is unclear.Moreover, for differentiation to progress, FGF signalling must decline.Why these signalling dynamics are required has not been determined.Here, we show that dephosphorylat

Estimation of soil permeability

Soils are permeable materials because of the existence of interconnected voids that allow the flow of fluids when a difference in energy head exists.A good knowledge of soil permeability is needed for estimating the quantity of seepage under dams and dewatering to facilitate underground construction.Soil permeability, also termed hydraulic conducti
