The cell membrane is a double-walled structure containing a cell's genetic code.
Luxury caskets often have a double lid, sometimes even a triple lid (the innermost being made of glass). In rare cases, caskets are even double walled (triple walled would be absolutely unusual), which means that the outer casket contains a complete inner casket, which can be taken out. Double walled caskets are much more heavy than double lid caskets, of course.
Because single pane glass is a lousy insulator. The layer of air between the two panes works as an insulator. This improves energy efficiency
it consists a double walled glass vessel having a vaccum between the walls.both these walls are silvered on the vaccum side.no heat can enter or leave the inner flask by convection oor conduction across vaccum.a small amount of heat can be gained by the flask through by radiation but the silver surface to control radiant heat and reduce it to a minimum
Conducted a lab at school measuring the strain on a soda can when it was opened. Back solving for the force as if the can were a thin walled pressure vessel led us to P = -54.447 +- 0.047288 Psi to 95% confidence.
this is question related to the strength of materials rather than the hydraulics the basic equation for the stresses in thick walled cylinders will give you the pressure at which the respective hydraulic cylinder can be operated. for radial stress=((piri2 )/ (r02 -ri2)) * ((1 - (ro2/r2))) where pi is the internal pressure of the cylinder ri is the internal radius of the cylinder. r0 is external radius of the cylinder. r is the radius of the point you have selected on the cylinder (this is mostly ri because it is the point were high stress is felt .apparently this formula gives the value of radial stress at point selected by you that is the 'r' value) for tangential stress=((piri2 )/ (r02 -ri2)) * ((1 + (ro2/r2))) adding the 'tangential stress' and the 'radial stress' would give you the value of the 'axial stress' this along with some 'factor of safety' value can determine the operating pressure of the hydraulic cylinder or in this case the internal pressure of the cylinder.
Pumpkins are plant and eukaryote. They have a double walled nuclear membrane binding the genetic material and many membrane bound organelles.
Chloroplast is a double walled structure which has a chorophyll (green pigment) which is responsible for the process of photosynthesis It is jelly like.
Eukarya has a doubled walled nucleus containing the genetic material and Bacteria and Archaea do not have contained genetic material. Eukarya has membrane bound organelles and the other two Domains do not. These are the pertinent differences.
A cell that is double walled is a plant cell. This is because the plant cells can't move so they need extra protection.

A double phospholipid bilayer surrounds the nucleus.
The walled citadel of Moscow containing the government offices of Russia is the Kremlin. The Kremlin consists of five palaces, four cathedrals, and the enclosing Kremlin Wall with Kremlin towers. The complex serves as the official residence of the President of the Russian Federation.
