Most important, in their ambivalence about letting their son or daughter go, parents need to beware giving a series of double messages that can weaken the only child s resolve to break the final ties of dependence upon them. 

If parents have any reason to believe that, despite their wishes and their warnings, experimentation is likely to occur, then they may want to consider giving that dreaded double message "For all the reasons we have told you, we do not want you to experiment but if you do, here are some precautions to take that might keep you from harm." This preparation for doing what parents do not want the child to do is not permission. It is protection. It is based on their realistic assessment of what the child is likely to do. And it begins with a statement about the nature of experimentation itself. 

Three insecurities can bedevil a young person at this departure point from doubt, from confusion, and from guilt. In response, parents need to beware their feelings of ambivalence at this trying time and avoid giving double messages that can place the late adolescent in a painful bind. 

Doubt arises when fear erodes confidence, with the young man or young woman wondering "Will I be able to separate from family and stand alone " Courage is going forward when confidence is lacking. Parents need to avoid the double message "We want you to be independent, but we re not sure you can make it on your own." Instead, an expression of faith would help "We believe you have what it takes to learn independence."... 

Confusion arises when lack of direction creates fear of an undetermined future. Courage is going forward when you don t know which way to go. Parents need to avoid the double message "We want you to make your own choices, but we don t want you to make the wrong ones." Instead, acceptance of uncertainty would help "It takes exploring, and trial-and-error learning, for people to figure out what they want to do in life."... 

The take home message of this section is that local and GGA functionals perform more or less similarly for IR and Raman intensities, whereas the hybrid ones offer a significant improvement, yielding results comparable or even better than MP2 for significantly less computational cost. In terms of basis sets, at least double-zeta sets augmented by flexible polarization and diffuse functions are needed. The POL basis set seems to offer a particularly good price/performance ratio. 

The reverse genetic approach relies on the construction of suitable libraries. The initial step is to homogenize the tissue and isolate the mRNA population. As mRNAs are single stranded and relatively unstable, they are first converted to their complimentary DNA (cDNA) sequence, and then into the more stable double-stranded cDNA molecule. The next step is to find a suitable vector that can carry the cDNA molecule and replicate itself multiple times. This will allow each message to be amplified to the large numbers of copies required for isolation and purification.

The surface tension was stated (Section 6.4.5), on general grounds, to be related to the surface excess of species in the interphase. The surface excess in turn represents in some way the structure of the interface. It follows therefore that electrocapillaiy curves must contain many interesting messages about the double layer at the electrode/ electrolyte interface. To understand such messages, one must learn to decode the electrocapillary data. It is necessary to derive quantitative relations among surface tension, excess charge on the metal, cell potential, surface excess, and solution composition. 

The genetic instructions for a cell are found in the DNA molecules. All DNA is derived from four different kinds of monomers, which we call nucleotides. DNA molecules are double-stranded two polymer chains are coiled together, their nucleotide units being associated as nucleotide pairs (see Fig. 5-7). The genetic messages in the DNA are in the form of... 

It turns out that we must protect the phenol as its methyl ether 127 and that 126 is best used as an amidine-ester rather than the double enamine. The synthesis is then quite short. We have barely scratched the surface of aromatic heterocyclic synthesis in this chapter but the encouraging message is that cyclisation is easy and that cyclisations to form aromatic compounds are the easiest of all. Disconnect with confidence ... 

The molecule of DNA is like a coded message. This message, the genetic information contained in and transmitted by nucleic acids, depends on the sequence of bases from which they are composed. It is somewhat like the message sent by telegraph, which consists only of dots, dashes, and spaces in between. The key aspect of DNA structure that enables storage and replication of this information is the famed double helix structure of DNA mentioned above.
