Small containers generally

J Chem. Phys., 52, 431 (1970)] is a relatively inexpensive one and can be used for calculations on quite large molecules. It is minimal in the sense of having the smallest number of functions per atom required to describe the occupied atomic orbitals of that atom. This is not exactly true, since one usually considers Is, 2s, and 2p, i.e., five functions, to construct a minimal basis set for Li and Be, for example, even though the 2p orbital is not occupied in these atoms. The 2sp (2s and 2p), 3sp, 4sp, 3d,. .., etc. orbitals are always lumped together as a shell , however. The minimal basis set thus consists of 1 function for H and He, 5 functions for Li to Ne, 9 functions for Na to Ar, 13 functions for Kand Ca, 18 functions for Sc to Kr,. .., etc. Because the minimal basis set is so small, it generally can not lead to quantitatively accurate results. It does, however, contain the essentials of chemical bonding and many useful qualitative results can be obtained. 

Droplet Dispersion. The primary feature of the dispersed flow regime is that the spray contains generally spherical droplets. In most practical sprays, the volume fraction of the Hquid droplets in the dispersed region is relatively small compared with the continuous gas phase. Depending on the gas-phase conditions, Hquid droplets can encounter acceleration, deceleration, coUision, coalescence, evaporation, and secondary breakup during thein evolution. Through droplet and gas-phase interaction, turbulence plays a significant role in the redistribution of droplets and spray characteristics. 

BIB refers to a sealed, sprouted (small too large, with or without dispensing valves) plastic film bag inside a molded rigid container, generally for packaging liquid products. Outer box may be made of disposable corrugated cardboard, disposable or reusable... 

Labpack Generally refers to any small containers of hazardous waste in an overpacked drum, but not restricted to laboratory wastes.

Incinerators that accept only liquid wastes either blend them with fuels or incinerate directly. In either case, the disposer generally pumps the contents from the container. Small containers are less desirable than the standard 200-liter drum. Incinerators that accept solid waste generally incinerate without removing the waste from the container, avoiding the hazards of opening containers. Some facilities will accept a variety of containers, including individual bottles. Others prefer to accept wastes in fiber packs, which is a combustible version of the lab pack used in landfills. 

Electron micrographs of the surfaces of salt crystallites decomposed to small extents (generally a < 0.09) revealed a very marked inhomogeneity in the density of nuclei [7]. Some surfaces contained large numbers of closely-spaced product crystallites, while others remained apparently unreacted. No dependence of nucleation density on reaction temperature could be recognized. 

Three channels have been implicated as potentially having a role in the access to the active site of CAT. The perpendicular (relative to the plane of the heme) or main channel has been considered as an access channel. The lateral or minor channel has been shown to be important, possibly as an inlet channel, in HPII and in small-subunit enzymes. A third channel has been identified, leading from the heme to the central cavity of the tetramer [200]. All three channels are quite narrow, particularly as they approach the heme-containing active-site cavity, and this restricts accessibility to relatively small molecules, generally not much larger than H2O2. Subtle differences in the size and shape of the channels may influence substrate entry or product exit, contributing to the differences in the reaction rates between different CATs [201]. 

Besides the comparatively long species discussed so far, short single-walled carbon nanotubes can be prepared as well (Figure 3.30). Generally they measure 2-6nm in diameter and about 50 nm in length. A conical tip with an internal angle of ca. 20° is situated on one end. The structure resembles a small container not unlike...

D. Generally, these ORM-D materials are destined for use in the home, industry, and institutions. The materials are in small containers, including aerosol cans, with a quantity that is usually a gallon or less.
