Alignment negative

The 1=34, 35, 36, 40 and 42 states essentially exhaust the possibilities to form low-lying positive parity states with 1 30 within the ten valence particles of 15 Er. The most low-lying fully aligned negative parity states are calculated for I = 38 , 39 corresponding to the rearrangements V(i13 2 7/2 13/2 h9/2 relative to the 42+ state. This seems consistent... 

FIGURE 5 The upper panel shows homogeneously aligned, negative contrast, and the lower panel shows homeotropically aligned, positive-contrast, single-polarizer guest-host device effects. 

Figure 6. Schematic drawing illustrating the dielectric reorientation of a homeotropically aligned negative dielectric anisotropy SmA phase being driven into a focal conic texture.

When no gap penalty is used then the Needleman-Wunsch alignment may contain a largt unrealistic number of gaps. The simplest type of gap penalty (other than not to have one) i to use a length-dependent scheme in which one assigns a fixed negative value for each insertio ... 

As shown by the above examples, the correct use of positive (4-) and negative (—) signs is important in shaft alignment. 

Orientation of polar molecules in an electric field. With the field off. polar molecules are randomly orientad. With the field on, polar molecules such as HF align their positive and negative ends toward the negative and positive poles of tire field, respectively. Nonpolar molecules such as H2 do not line up. 

Figure 12-5 illustrates the solvation of Na and Cl" ions as NaCl dissolves in water. A cluster of water molecules surrounds each ion in solution. Notice how the water molecules are oriented so that their dipole moments align with charges of the ions. The partially negative oxygen atoms of water molecules point toward Na cations, whereas the partially positive hydrogen atoms of water molecules point toward Cl" anions.
