However, the four light bulbs aligned on the sill yield electric lighting clues.
Recirculation within the basin affects the density at the outflow and thus influences the internal hydraulic control at the sill.
Intrusion is particularly prevalent in shale horizons because they are mechanically weak, and therefore preferential sites for the emplacement of sills.
All the main rooms had a low sill so that the pensioners could look out.
The software would search in its database and assign a standard sill height to the window.
It is of interest to know how the processes within the basin influence the exchange flow at the sill.
A 50 m thick, highly magnetic gabbro sill intrudes siltstones of the lower parts of the formation providing an excellent marker layer for mapping.
Include a continuous sill flashing with panned-up ends and inboard leg; the waterproofing layer should counterflash the inboard leg of the flashing system.
