    Notes: Summary 1. Within the cat geniculate ganglion three distinct neural populations were definable on the basis of single unit recordings. These three neural populations were designated “ear units”, “regular discharge units” and “tongue units.” Units from these three populations tended to be located in different regions of the ganglion and were influenced by different types of stimulation to different parts of the body. 2. Ear units seemed to constitute a uniform functional population, with the major differences between units being the external locus of projection. Ear units typically had no spontaneous activity. They were discharged by dynamic displacements of hairs on the skin of the inner surface of the ear. 3. Regular discharge units were classified into three types on the basis of their spontaneous activity patterns. Discharge of most of the units could be affected by static dislocations of tissues of the soft palate and pharynx. Discharge patterns, evoked and spontaneous, tended to be extremely regular. 4. Tongue units seemed to constitute an extremely diverse population. Wide variability was shown on every measure taken of tongue unit activity. Spontaneous activity patterns varied markedly from unit to unit, with bursting discharge common. Most units could be discharged by electrical stimulation of papillae of the tongue, although the number of stimulatable papillae varied from unit to unit as did latency measures. Some tongue units were discharged by mechanical stimulation of the tongue, most by chemical stimulation of the tongue (with salt, acid, quinine and common cat foods), and some by both.

    Dynamic mechanical relaxation effects in some poly(arylene sulfones) (1970)

    Notes: Poly-4,4′-oxydiphenylenesulfonyl and poly-4,4′-methylenediphenylenesulfonyl were synthesized by an electrophilic substitution polymerization of the arylene monosulfonyl chloride monomers. The glass-transition temperatures Tg of these polymers were determined by calorimetric and dynamic mechanical measurements, and the number-average molecular weights were determined by vapor-pressure osmometry. Both polymers were found to have the same Tg at equivalent molecular weight; the limiting value at high molecular weight is 238°C. Both polymers have two dynamic mechanical relaxation peaks at temperatures far below Tg. One is in the neighborhood of 0°C, and the other is at -110°C. Plausible origins for these relaxations, and the absence of any near 0°C in poly(4,4′-isopropylidenediphenylene-co-4,4′-sulfonyldiphenylene dioxide), are discussed.

    Carbon-13 NMR of ethylene-1-olefin copolymers: Extension to the short-chain branch distribution in a low-density polyethylene (1973)
    New York : Wiley-Blackwell

    Notes: As model polymers for isolated short-chain branches in low-density polyethylene, a series of ethylene-1-olefin copolymers was examined by use of 13C NMR at 25.2 MHz. An array of 13C resonances was observed that could be associated independently with methyl through amyl branches. The 13C chemical shifts became insensitive to branch length with hexyl and longer branches. Assignments of the various carbon resonances associated with branching were accomplished by using off-resonance decoupling techniques and the behavior of alkane chemical shifts previously observed by other investigators. The ratio of certain backbone and branch resonances could be used to establish the short-chain branch distribution in a low-density polyethylene.

    Dielectric relaxation of collagen and gelatin (1973)

    Notes: Dielectric dispersions of reconstituted collagens and gelatin were measured from 0.1 to 10 kHz and -160 to +160°C. At 0.1 kHz there is a γ transition at -80°C which is attributed to the H2O-coupled local modes. The process has an activation energy of 7.5 kcal. A devitrification process is observed at 10-20°C. Both of these processes have their counterparts in the dynamic mechanical measurements. The tan δ values are up to 3 times as great for the dynamic mechanical dispersions. There is an additional hightemperature dielectric loss transition which does not correspond to any seen with the mechanical experiments. A probable mechanism for this absorption is the Maxwell-Wagner-Sillars effect.
