Rearing density

Estimation of the rearing density is a more complex process and depends upon the type of substrate used for rearing the spat ropes or screens. 

Polachrome films are used in standard 35-mm cameras, and the sHdes are mounted in standard size 5x5 cm (2x2 in.) mounts for projection in conventional 35-mm equipment. Because of the density of the color base (about 0.7) the Polachrome sHdes are most effective when viewed either using a bright rear projection unit or in a weU-darkened projection room. 

For material of 40-lb/ft maximum bulk density. Mixer can be tilted. Rear end charger. 

So far as steric effects are concerned, the least energy-demanding direction of approach by the nucleophile to the carbonyl carbon atom will be from above, or below, the substantially planar carbonyl compound. It is also likely to be from slightly to the rear of the carbon atom (cf. 12), because of potential coulombic repulsion between the approaching nucleophile and the high electron density at the carbonyl oxygen atom ...

Introduction. In the absence of all contact with an external solid, a prime mover placed in a fluid of finite or even zero density can propel itself by ejecting a fluid or solid mass toward the rear. By convention we say that this mover is propelled by jet propulsion, although the propulsive thrust really results from the effects of pressure and friction exerted on the wall of the hollow interior of the mover by the solids or fluids moving in the interior toward the exhaust nozzle ... 

A fin-stabilized projectile must have its center of mass well forward of its center of pressure. This means that the point thru which gravity can be said to act must be well in advance of the point at which the aerodynamic forces act. A good example of this is a metal dart which has a brass body of considerable density and fins placed on a lightweight wooden boom well to the rear...
