The secondary lamella is covered by a squamous epithelium that generally shows a thickness of one or two cell layers.
1], slight alterations were observed such as epithelial lifting, fusion of secondary lamellae, aggregation of cells in the primary lamella and severe alterations such as telangiectasia and aneurysms in a few secondary lamellae.
Histological sections of gills of Oreochromis niloticus specimens: a) Normal gill (1: primary lamella, 2: secondary lamella, H&E, 400x), b-d) Histopathological alterations.
The goal of this project was to design such an automatic system for continuous monitoring of lamella geometry quality after re-sawing using sash-gang saws.
A two-sided laser triangulation system known as a sandwiching measurement method has been proposed for assessment of lamella thickness (Fig.
The lamella principle is to have a series of closely spaced inclined plates to increase the settling area available per unit of plan area.
The thickener consists of an upper tank containing the lamella plates which are inclined at 45 [degrees] or 55 [degrees], and a conical or cylindrical sludge hopper.
At the end of the pressing zone is a flying cutoff saw which reads the gap between the top lamellas
and cuts the planks to the length of the top lamellas
It is easy for the operator to make adjustments to different block sizes and lamella
sizes on the touch screen.
The higher the nickel content, the faster the cooling rate occurred, the narrower the kamacite lamellas
