    Notes: Approximately 0.030%, 0.012% and 0.005% (v/w), in wet weight, of volatile oils were obtained from raw, baked and deep-fried shallots, respectively. These oils have been studied by a gas chromatograph coupled to a mass spectrometer. The flavor components of these oils can be classified in the following categories: thiols, monosulfides, disulfides, trisulfides, thiophenes and oxygen compounds. After heating (baking or deep-frying) of the shallot, a sharp increase in the amount of dimethylthiophenes was observed and the alkyl propenyl disulfides decreased.

    Notes: The influence of postmortem time and incubation temperature on the release of lysosomal enzyme activity and their effect on the muscle connective tissue have been investigated. Semimembranosus muscles from nine steers were restrained and held at 2°C (C) for 60 hr; five portions of each muscle were elevated to 37°C (HT) for different 12-hr sequences of the 60 hr. It was found that HT incubated samples showed a greater release of lysosomal enzymes (β-galactosidase and β-glucuronidase), regardless of the time postmortem when high temperature conditioning occurred. The inclusion of hyaluronidase or β-galactosidase in the sample incubation solution resulted in an increase in the dissolution of collagen fibers by collagenase, which indicates that lysosomal glycosidases may also participate in the dissolution of collagen fibers during postmortem aging.

    Notes: Summary The presence of cells exhibiting leucine-enkephalin-, substance P- and glutamate decarboxylase-like immunoreactivity was demonstrated in dissociated cultures from newborn rat neostriatum. The size and shape of the enkephalin-immunoreactive cells varied, but they were generally larger than substance P- and glutamate decarboxylase-immunoreactive cells, which formed relatively uniform cell populations. Cells of apparently non-neuronal origin did not show any immunoreactivity. It is unlikely that enkephalin is present in the same cells that contain substance P or glutamate decarboxylase because of norphological differences between these cells. The possible coexistence of substance P and glutamate decarboxylase in the same cells however, could not be excluded. The results of this study confirm that the cell bodies of neurons containing three possible neurotransmitters are located in the neostriatum.

    Notes: Summary Breeding tobacco resistant to CMV using Holmes' resistant line was initiated in 1966. The resistance was controlled by five genes. N from N. glutinosa, rm1 and rm2 from Ambalema and t1 and t2 from T.I. 245. The genotype of Holmes' resistant line was assumed to be NNrm1rm1rm2rm2t1t1t2t2, which showed a few-small-late (FSL) lesion reaction to TMV. This reaction facilitates the selection of CMV resistant plants in a segregating population. Hicks Broadleaf was crossed to Holmes' resistant line and backcrossed to the susceptible varieties Vam-fen-Hicks, Kutsaga 51 and T.T.4. Two resistant lines, 418 and 470, were selected and tested for their CMV resistance, yield and agronomic characters in 1976–1979. The % reduction of infection rate when compared with a check was 41.8% and 52.7% respectively. The two lines outyielded the check and had slightly higher value/kg leaf tobacco and lower % midrib. They were also taller and later maturing. Line 470 showed slight leaf-wilting in the early growth stage, which disappeared after topping. Smoking tests showed that the two lines had better scores than check T.T.5. The nicotine and tar contents in the cigarette smoke stream proved that the leaf quality was acceptable. The lines 418 and 470 were registered as T.T.6 and T.T.7.

    Notes: Summary 17β-Estradiol (E2) rapidly and reversibly decreases the synthesis of follicle-stimulating hormone (FSH) in primary dispersed cell cultures of ovine pituitaries. Similarly, E2 also causes a decrease in the messenger RNA for the beta subunit of ovine FSH (FSIIβ-mRNA) as measured in an in vitro translation assay. These results are consistent with the concept that E2 directly regulates either transcription of the FSHβ gene or processing of FSHβ-mRNA in sheep. Of additional interest is the observation that pituitary cultures from various species respond differently to E2 in terms of FSH synthesis. For example, E2 stimulates FSH synthesis in rat pituitary cultures, has no effect in similar rabbit cultures, and inhibits FSH synthesis in ovine cultures. Thus, a set of eukaryotic ‘mutants’ may exist to aid studies of the effect of E2 on FSH synthesis and secretion.

    Notes: Abstract For the first time the intrinsic tensile stress-strain behaviour of polystyrene was measured in an inert atmosphere (He) from 77 to 350 K. The intrinsic tensile strength decreases monotonically with increasing temperature with completely brittle behaviour below 231 K and crazing without shear flow at higher temperatures. The behaviour in N2, Ar, CH4, CO2, H2S, and N2O was observed with the relative pressure being the important parameter. The softening depended on the square root of the relative pressure. A calculation was made of the concentration of absorbed gas to produce a given amount of softening. The question of why polystyrene is a brittle solid and thus crazes instead of shear flows is discussed.

    Notes: An approach for the numerical solution of flow problems based on the concept of fundamental solutions of differential equations is described. This approach uses the finite element methodology but does not rely on the concept of variational principle or that of residuals. The approach is shown to be well-suited for many types of flow problems. Various applications of this approach are discussed in this paper, with particular emphasis placed on the solution of potential flows and viscous flows containing appreciable regions of separation.
