Loose packed

Ammonia. Small quantities of ammonia may be prepared with the aid of the apparatus depicted in Fig. II, 48,4. Concentrated ammonia solution (sp. gr. 0-88) is gently heated in the flask surmounted by an efficient reflux condenser. The gas is dried by passage through the tower which is loosely packed with soda lime or quicklime, and is then passed... 

For plastic-bonded materials, no clear-cut expression for the coercivity is known. It may be expected that it is rather similar, but with a smaller influence of B. For loosely packed powders, the B influence has become zero and should be multiphed by 0.48 to account for the isotropy (71). In all cases high coercivity is obtained by using small grains with limited plate-like shape, ie, the value of Nis not too high. 

Although most cakes consist of polydisperse, nonspherical particle systems theoretically capable of producing more closely packed deposits, the practical cakes usually have large voids and are more loosely packed due to the lack of sufficient particle relaxation time available at the time of cake deposition hence the above-derived value of 17.6 pm becomes nearer the 10 pm limit when air pressure dewatering becomes necessary. 

Mica splittings are processed from lower quaUty blocks and from sheets too thin for blocks and unsatisfactory for producing film. The splittings are packed for sale in three ways book form, which are laminae spHt to the desired thickness from the same book of mica, then dusted with mica dust, and restacked in book form pan packed, in which splitting layers are placed evenly in a pan, and each layer separated by a thin sheet of paper then pressed together and loose packed, in which splittings are si2ed with screens then padded loosely in a wooden box for shipment. 

Variations on the a helix in which the chain is either more loosely or more tightly coiled, with hydrogen bonds to residues n + 5 or n + 3 instead of n + 4 are called the n helix and 3io helix, respectively. The 3io helix has 3 residues per turn and contains 10 atoms between the hydrogen bond donor and acceptor, hence its name. Both the n helix and the 3to helix occur rarely and usually only at the ends of a helices or as single-turn helices. They are not energetically favorable, since the backbone atoms are too tightly packed in the 3io helix and so loosely packed in the n helix that there is a hole through the middle. Only in the a helix are the backbone atoms properly packed to provide a stable structure. 

Ruths and Granick [95] have studied the self-adhesion of several monolayers and adsorbed polymers onto mica. For loose-packed monolayers, the adhesion, in excess of a constant value observed at low rate, increased as a power law with the square root of the separation rate. In the case of adsorbed diblocks, the excess adhesion increased linearly with logarithmic separation rate. The time effects were ascribed to interdigitation and interdiffusion between the contacting layers. 

Permeability. The low density of plastics is an advantage in many situations but the relatively loose packing of the molecules means that gases and liquids can permeate through the plastic. This can be important in many applications such as packaging or fuel tanks. It is not possible to generalise about the performance of plastics relative to each other or in respect to the performance of a specific plastic in contact with different liquids and gases. 

Whenever the polymer crystal assumes a loosely packed hexagonal structure at high pressure, the ECC structure is found to be realized. Hikosaka [165] then proposed the sliding diffusion of a polymer chain as dominant transport process. Molecular dynamics simulations will be helpful for the understanding of this shding diffusion. Folding phenomena of chains are also studied intensively by Monte Carlo methods and generalizations [166,167]. 

Soil specific weight is the measure of the concentration of packing of particles in a soil mass. It is also an index of compressibility. Less dense, or loosely packed, soils are much more compressible under loads. Soil specific weight may be expressed numerically as soil ratio and ptorosity (porosity for soils being basically the same definition as that for rocks discussed earlier in this section). Soil porosity e is... 

Experiment shows that heat is absorbed as iodine dissolves. The regular, ideally packed iodine crystal gives an iodine molecule a lower potential energy than does the random and loosely packed solvent environment. We see that the second factor, tendency toward minimum energy, favors precipitation and growth of the crystal. 

The tube B is loosely packed with purified glass wool soaked in lead acetate solution (to remove hydrogen sulphide and trap acid spray), and C is a capillary tube (4 mm external and 0.5 mm internal diameter). Place 1.0 mL... 

It also can be detond by an initiator when loosely packed in shells (Ref 57)...
