    Notes: The effects of antioxidants (0.01 or 0.02% of total fat), salt level (0.375 or 0.750%) and salt type (NaCl, KCl or a 65% NaCl + 35% KCl combination) in a 2 × 2 × 3 factorial arrangement on the quality of restructured beef steaks were determined. Meat blends with 0.02% antioxidant had lower thiobarbituric acid (TBA) values than those with 0.01% after 85 to 155 days of frozen storage. Steaks with no salt (pooled across antioxidant levels) had lower TBA values than steaks with any salt type after 85 days storage or either level of salt after 155 days storage. Steaks with either level of added salt resulted in higher ratings for juiciness, saltiness and overall palatability than steaks with no added salt. Juiciness, flavor desirability, saltiness and overall palatability ratings generally were higher for restructured steaks made with NaCl or NaCl + KCl compared to those made with KCl. KCl at 35% of total salt could serve as a NaCl substitute in restructured beef steaks.

    Single-Link Cluster Analysis As A Method to Evaluate Spatial and Temporal Properties of Earthquake Catalogues (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Geophysical journal international 100 (1990), S. 0

    Notes: Single-link cluster analysis is a straightforward method to quantitatively measure the degree of clustering or isolation of groups of elements in a set, such as a catalogue of earthquakes. to apply single-link cluster analysis to a set of N earthquakes, individual earthquakes are first linked to their nearest neighbours to form event sub-groups. the process is then repeated and each sub-group linked to its nearest neighbour, recursively, until N-1 links are found to join all the earthquakes. This paper shows how knowledge of these links can be used to divide a group of earthquakes into any number of spatial clusters. With various modifications this analysis can identify earthquake nests, isolated events, aftershock sequences, and zones of seismic quiescence. to illustrate this method we apply it to; (i) a global data set of 2178 earthquakes having mb of 5.8 or greater reported by the International Seismological Centre (ISC) between 1964 and February 1986, and (ii) sets of earthquakes having mb of 4.9 and greater as reported by the ISC, occurring in Central America and in the Aleutians. to facilitate comparison with real data, this study also investigates the distribution of link lengths for synthetic events placed randomly on 1-D (circular line), 2-D (circular area) and 3-D (spherical volume) geometries. If we remove links between nuclear explosions from the ISC data, the resulting link distribution is quite similar to that for synthetic events placed along a 1-D fault. For the shortest links, the similarity improves markedly if the synthetic fault has a finite width, or if relative location errors cause events to be located away from the fault trace, with a standard deviation of about 15 km.

    [14C]-Assimilate translocation in the light and dark in celery (Apium graveokns) leaves of different ages (1990)

    Notes: The 2 major photosynthetic products and translocated carbohydrates in celery (Apium graveolens L.) are sucrose and the sugar alcohol, mannitol. Sucrose is produced and utilized in leaves of all ages. Mannitol, however, is synthesized primarily in mature leaves, utilized in young leaves and stored in all leaves. Here we show that mannitol export was lower from young, expanding leaves than from older leaves. After a 10 min pulse of 14CO2 and a 2 h chase in the light or dark there was more radioactivity in sucrose than in mannitol in petiole tissues from leaves of all ages. However, after a chase of 15 h in the dark or 6 h in the light followed by 9 h in the dark, mannitol was the predominant [14C]-labeled carbohydrate remaining in all leaf and petiole tissues. Thus, newly synthesized sucrose was apparently exported at a faster rate than mannitol and more mannitol was partitioned into vacuolar storage pools than was sucrose. It also appears that in the light both sucrose and mannitol were exported, but in the dark, once sucrose pools were depleted, mannitol remained as the predominant substance translocated. Both mannitol and sucrose were unloaded into petiole storage parenchyma tissue, but sucrose was hydrolyzed prior to storage.

    Uniconazole-induced thermotolerance in soybean seedling root tissue (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 79 (1990), S. 0 
    Details
    ISSN: 1399-3054
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Soybean [Glycine max(L.) Merr. cv. A2] seeds were germinated in 0 or 1 mg 11 (3.4 uM) uniconazole, after which seedling roots were excised and exposed to 22 or 48°C for 90 min. Prior to the temperature treatments there were few ultrastructural differences between uniconazole-treated seedling roots and the controls. Following exposure to 48°C, electron micrographs revealed near complete loss of normal ultrastructure in control epidermal root cells, whereas cellular integrity was maintained in treated roots, indicating that uniconazole conferred tolerance to high temperature. Total electrolyte, sugar and K+ leakage were all greater from control roots than treated roots during exposure to 48°C. Proline content in the roots was unaffected by uniconazole at 22°C but was 25–30% greater in treated tissue than in controls following exposure to 48°C. Malondialdehyde content was unaffected by uniconazole at 22°C but was nearly 20% less in treated tissue than in controls following high temperature exposure. This indicates that uniconazole decreased high-temperature-induced lipid peroxidation. Uniconazole elevated several antiox-idant systems in the roots, including water-soluble sulfhydryl concentration and catalase, peroxidase and superoxide dismutase activities. These findings are consistent with the hypothesis that uniconazole-induced stress tolerance is due, at least in part, to enhanced antioxidant activity which reduces stress-related oxidative damage to cell membranes.

    Notes: Egg yolk solids defatted with hexane were incorporated into frozen and spray-dried scrambled egg products. Part of the egg oil removed was replaced with nonfat oil replacers. Both products were evaluated by sensory panels. The frozen product was compared with frozen whole egg and a nonyolk, commercial frozen product. The spray-dried product was compared with a nonyolk, commercial dried product. In the frozen products, the whole egg was preferred over both the defatted frozen product and nonyolk, commercial frozen product, with the defatted and nonyolk products being equally acceptable. In the dried products, the spray-dried scrambled eggs were preferred over the nonyolk, commercial dried product. The products formulated from defatted yolk solids contained 84% less lipid and 79% less cholesterol than products made from fresh whole eggs.

    A Proposal to Use Chlorine-36 for Monitoring the Movement of Radionuclides from Nuclear Explosions (1990)

    Ground water monitoring & remediation 10 (1990), S. 0

    Notes: Chlorine-36 has been produced in large amounts by hundreds of nuclear explosions on the Nevada Test Site as well as 12 off-site explosions at eight locations in five states. Continued monitoring of the redistribution of radionuclides by subsurface water is of concern in most of the areas affected by the detonations. Chlorine-36 has the following advantages as a built-in tracer for this redistribution: its mobility is equal to or greater than water, its long half-life assures its continued usefulness over long periods, collection and storage of samples is simple, it is not subject to vapor transport at ordinary temperatures, its natural background is very low, and it does not form insoluble precipitates. Chlorine-36 from the Gnome event near Carlsbad, New Mexico, illustrates how 36C1 can be used to help study the redistribution of radionuclides in the soil profile. Chlorine-36 is also potentially useful as a tracer to study movement of contaminants around large nuclear reactor complexes and near respositories for radioactive waste.

    Notes: Abstract Chromosomal restriction fragments of Corynebacterium ulcerans and C. diphtheriae, containing an integration site for corynephages of the β family, show homology on Southern blots. Homologous DNA in also found in the soil isolate C. glutamicum, although this strain is not susceptible to gb-corynephages. Three of these DNA fragments, one for each bacterial strain, and a fragment of γ-corynephage DNA previously shown to contain the phage integration site, were cloned and sequenced. Alignment of the 3 bacterial sequences shows a very high degreee of homology in a stretch of ca 120 nucleotides, whereas the rest of the sequences is generally non-homologous. Within this common bacterial portion, a segment of ca. 96 nucleotides (core sequence) is also highly homologous to the plague sequence. The first half (ca. 50 bp) of the core sequence is identical in all aligned sequences whereas the second half, which is largely occupied by a stem-and-loop structure, contains point mutations peculiar to each clone. The described sequences are likely to be involved in phage integration/excision processes.

    Notes: Abstract Subcloning and protoplast transformation studies identified a 2.6 kb fragment of Corynebacteriumdiphtheriae plasmid pNG2 which contains an origin of replication (oriR). Molecular combination of the 2.6 kb oriR cartridge with Escherichia coli plasmid pUC18CmR enabled the E. coli cloning vector to replicate within several species of Corynebacterium host cells. A 2.6 kb plasmid formed from the oriR cartridge alone is capable of replicating in E. coli. This suggests that a single origin could be used in vectors shuttling between Corynebacterium spp. and E. coli.
