To fool the eye against them appearing narrower as they rise
"Entasis" refers to the taper of a column.
A convex curve in the shaft of a column
The main part of the Parthenon's column is called the shaft.
They did that through entasis, creating an optical illusion. Normally the columns would seem to become narrower higher up when you were looking up at them. Entasis, a little bulging out in the middle of the column segments made the column appear straight and of uniform width.
The Parthenon was a temple on the acropolis of Athens and was built by the Greeks.
Parthenon, Vatican Obelisk, Nelson's Column, Eiffel Tower,
The Parthenon is a temple of the Doric order with eight columns at the façade, and seventeen columns at the flanks.
Doric - styled column;) ~ In case your wondering... well everyone gets to put an answer so Idunno if it's right or not. Well... it is. It said so in my homework packet and history book. ;)
neural tissue damage, swelling, and infection into the spinal fluid and brain with an opening in the spinal column
Currently doing Classical Civilisation GCSE, not only did they have Doric style columns (characterised by their rather plain capital (that little ring thing at the top of the column) and lack of entasis/base) but they also housed Double Doric columns in the naos with it's cult statue. I don't why but I find that so cute, they're like mini-versions of the regular Doric Columns. You should check out the Assasin's creed Parthenon and look at their columns, or some artist reconstructions as I can't really put these into words that well. Plus, I'm only at GCSE, this might not be the most informed explanation of their columns. Feel free to correct me if need be
A congenital malformation in which the spinal column is cleft at its lower portion, and the membranes of the spinal cord project as an elastic swelling from the gap thus formed.
The molecular sieving matrix is swelled prior to packing the column to enhance its porosity and improve the separation efficiency of the packed column. Swelling allows the matrix to expand, creating more uniform pores that facilitate the selective passage of molecules based on size. This pre-treatment also helps to eliminate air pockets and ensures a more consistent packing density, which is crucial for optimal chromatographic performance. Overall, swelling optimizes the interaction between the matrix and the analytes, leading to better resolution in separations.
