The common use of soil-fertility control data in Croatia includes properties such as soil pH, organic matter content and plant-available phosphorus (P) and potassium (K) extracted by ammonium lactate (AL) solution. These data are commonly used for fertilizer recommendations for both field vegetable (Lončarić et al., 2003) and arable crops (Vukadinović et al., 1996). Also, the same soil data hav...

This paper begins a series studying D-modules on the Feigin-Frenkel semi-infinite flag variety from the perspective of the Beilinson-Drinfeld factorization (or chiral) theory. Here we calculate Whittaker-twisted cohomology groups of Zastava spaces, which are certain finite-dimensional subvarieties of the affine Grassmannian. We show that such cohomology groups realize the nilradical of a Borel ...

Semiconductor ZnO aerogels were synthesized by a sol–gel process with different concentrations (2.5–7.5 wt.%) of Al (n-type) or Na (p-type) and dried under supercritical CO2. The materials calcined at 500 °C to remove the organic content crystallize ZnO. microstructure ZnO-based comprises porous structure hexagonal platelet-shaped interconnected particles. bandgap doped decreased significantly ...
