A simple 2D non-stationary parcel model has been elaborated by coupling kinematics and microphysics of ice crystals, for the purpose retrieving realistic trajectories in a cirrus uncinus, with hooked-shape head or cap, trail virga, observed lifetimes. Prescribed ambient physics includes vertical profiles horizontal winds updraft, air temperature humidity. Modelled combines mass variation deposi...

Studying the spatial and temporal variability of soil micronutrients their effects on plant growth is important for implementing precision-farming and/or economizing fertilizer management. The present investigation was done through sampling (0–20 cm depth) from three locations in central Ethiopia. tools employed include, descriptive classical statistics. concentrations available copper ra...
