    Notes: Abstract For the period December 1970, comparison is made between the monthly average analyses (mapped fields) of the Backscatter Ultraviolet (BUV) total ozone data and the ground-based observations. In particular, significant differences of over 50 Dobson units are noted over the region of the North Atlantic Ocean with the BUV of greater magnitude than the ground-based data. As part of the overall verification program, both analyses are compared against the 100 mb height fields. The results indicate that the BUV analysis in the region of question is the more consistent of the two.

    Notes: Abstract  Degradation of land in vulnerable areas can be significantly reduced by the maintenance or establishment of plant cover and diversity. Animals can facilitate plant diversity by grazing, by dispersing seeds or by contributing, through excreta, to the heterogeneous distribution of nutrients in soil. We investigated the latter property by examining the effects of rabbit (Oryctolagus cuniculus L.) dung deposition on soil properties in three adjacent plant communities at a semi-arid site in south-east Spain. Rabbit faecal pellets had concentrations of total N and P comparable to dung of stock animals, with K and Mg somewhat lower, although decomposition rates at this site are evidently very low. There was no significant difference in pH, but conductivity and concentrations of organic C, N (as NH4 + and NO3 –), K, P and Mg in soils from rabbit latrines were significantly greater relative to controls in each community. Barley plants grown as a bioassay of soil fertility had significantly greater total biomass, and lower root : shoot ratios in latrine compared to control soils. There were differences among communities in conductivity and concentrations of N, P and organic C under latrines which were reflected in the bioassay. Although latrines only comprised approximately 0.1% of the ground surface area in each community, they make significant localised contributions to soil fertility and may therefore be important in establishing and maintaining plant cover.

    Notes: Meat emulsions or batters made with a retail food processor were compared to batters produced by three commercial machines (silent cutter, Schnellkutter, and emulsifier) and two laboratory machines (small size cutter and blender) for suitability in laboratory studies. Batters were evaluated for post-heating fat losses and smokehouse water losses. Stabilities of the finished frankfurters were evaluated by severe cooking weight changes, penetration forces, fat droplet sizes, and sensory qualities. The food processor was comparable to the other machines for producing high quality batters and had the advantage of being inexpensive, economical with ingredients, and time-saving.

    Notes: The effects of processing and use of pro- and antioxidant additives on the methionine content of frankfurters were examined. Emulsification and cooking-smoking had no significant effect on the methionine content, but high peroxide fat or sodium ascorbate lowered the methionine content of the raw emulsions, presumably by oxidation. Cooking-smoking acted to restore the methionine level. Interaction of spice and nitrite on methionine levels was significant. Cooking and/or spices reduced the peroxide numbers of the frankfurters.

    Notes: We have demonstrated the use of superconducting transition edge sensors for the wide-band detection of individual photons from the mid infrared (IR), through the optical, and into the far ultraviolet (UV). These tungsten transition edge sensors are squares about 18 μm on a side and detect single photon events above a threshold of 0.3 eV (4 μm wavelength), with an energy resolution of 0.15 eV full width at half maximum, and with a risetime (falltime) of .5 μs (60 μs). The calibration data extend up to the UV cutoff of the fiber optic feed at 3.5 eV (350 nm). © 1998 American Institute of Physics.

    Notes: A comprehensive study of x-ray stimulated luminescence has been carried out on four types of high-purity, amorphous silica (a-SiO2). Both high OH and low OH as well as oxygen-excess and oxygen-deficient materials were studied. The room-temperature, visible x-radio luminescence (XRL) was measured continuously as a function of x-ray dose from zero to 400 Mrad volume average dose. In addition to the XRL measurements, electron paramagnetic resonance (EPR) was used to determine the concentrations of the two key radiation-induced defects, the E′ center and the nonbridging oxygen hole center (NBOHC). The XRL spectra were deconvolved into four Gaussian components with centers at 1.9, 2.2, 2.6, and 2.75 eV. The same centers and widths could be used to describe the spectra in all four types of a-SiO2, only the intensities varied. The 2.6 and 2.75 eV lines are strongly dose dependent, rising from near zero intensity at zero dose in all four materials. These two lines are strongly correlated with each other; they have essentially the same dependence on dose and sample type. This correlation suggests that these two lines are due to the same radiation-induced defect, or to closely related defects. The dose dependence and sample-to-sample variation of these two lines bear some similarities to the E′ concentrations. In contrast to the 2.6 and 2.75 eV lines, the 1.9 eV line has a high intensity at the lowest doses measurable. A simple phenomenological model is proposed to describe the 1.9 eV XRL line. This model involves two populations of defects; one population is present at zero dose and is assumed to be dose independent, while the second population is dose dependent. Evidence is presented that the dose-dependent defect is the NBOHC. The XRL due to the dose-independent population may be associated with a transient response to the x rays, or to a metastable defect; this population may not be observable in post-irradiation experiments such as EPR and conventional photoluminescence. Similar to the 1.9 eV line, the 2.2 eV line also has relatively high intensity at the lowest measurable x-ray dose. The behavior of this line is in general agreement with the self-trapped exciton model. © 1999 American Institute of Physics.

    Notes: The effect of nitrate uptake on the subcellular distribution of tissue nitrate in 2–5 mm maize root tips was investigated by two complementary methods. First a novel in vivo analysis using 133Cs nuclear magnetic resonance (NMR) was used to demonstrate changes in the cytoplasmic and vacuolar pools during caesium nitrate uptake. This method depended on interpreting the nitrate-induced changes in the positions of the cytoplasmic and vacuolar caesium signals. The assignment of the signals was confirmed by using in vivo39K NMR to observe the displacement of cytoplasmic potassium into the vacuole during caesium uptake, and in vivo133Cs NMR to observe the displacement of cytoplasmic caesium into the vacuole during potassium uptake. Secondly nitrate-selective microelectrodes were used to quantify the change in the cytosolic nitrate activity that occurred in the outermost cells of root tips under the same conditions. Both methods showed that the detected nitrate pool increased over a period of 8–10 h in the presence of 10 m m nitrate and it is concluded that the data provide support for the view that homeostasis in the cytosolic and cytoplasmic nitrate pools is not necessarily an invariant characteristic of root tips.
