    Notes: Abstract The Rp3 locus of maize conditions race-specific resistance to a fungal rust pathogen, Puccinia sorghi. Both morphological and DNA markers were employed to characterize alleles of Rp3 and to accurately position Rp3 on the maize genetic map. DNA marker polymorphisms distinctive to each Rp3 allele were identified, allowing the identification of specific Rp3 alleles in cases where rust races that differentiate particular alleles are not available. In a population of 427 progeny, Rp3 and Rg1 were found to be completely linked, while Lg3 was approximately 3 cM proximal on the long arm of chromosome 3. In this same population, 12 RFLP markers were mapped relative to Rp3; the closest markers were UMC102 (about 1cM distal to Rp1) and NPI114 (1–2 cM proximal). These and additional DNA probes were used to characterize the nature and extent of flanking DNA that was carried along when six different Rp3 alleles were backcrossed into a single background. Depending upon the allele investigated, a minimum of 2–10cM of polymorphic DNA flanking the Rp3 locus was retained through the introgression process. In addition, many of the probes that map near Rp3 were found to detect an additional fragment in the Rp3 region, indicating that portions of this chromosomal segment have been tendemly duplicated. The materials and results generated will permit marker-assisted entry of Rp3 into different maize backgrounds and lay the foundation for the eventual map-based cloning of Rp3.

    Notes: Abstract Rp1 is a disease resistance complex and is the terminal morphological marker on the short arm of maize chromosome 10. Several restriction fragment length polymorphisms (RFLPs), which map within 5 map units of Rp1, were examined to determine if they are also complex in structure. Two RFLP loci, which mapped distally to Rp1, BNL3.04 and PIO200075, existed in a single copy in all maize lines examined. These two loci cosegregated perfectly in 130 test cross progeny. Two RFLP loci that map proximally to Rp1 had unusual structures, which have not yet been reported for maize RFLPs; the loci were complex, with variable numbers of copies in different maize lines. One of the loci, NPI285, occasionally recombined in meiosis to yield changes in the number of copies of sequences homologous to the probe. The other proximal locus, detected by the probes NPI422, KSU3, and KSU4, was relatively stable in meiosis and no changes in the number of restriction fragments were observed. The similarity in map position between Rp1 and the complex RFLP loci indicate there may be genomic areas where variable numbers of repeated sequences are common. The structure of these complex loci may provide insight into the structure and evolution of Rp1.

    Description / Table of Contents: Summary Use of the Endochronic Theory on Rock Salt On the basis of the endochronic theory a material model which can describe the behavior of rock salt is developed. This study presents and follows in a modified form the earlier work of Valanis in metals and Bazant-Bhat in concrete. The deformation characteristics of rock salt, subject to extensive creep, are described and explained by an analogous rheological model. This model is used to determine the material functions and constants for the endochronic formulation. The material law is written in tensor form and keys for its use in a computer program are supplied.
    Abstract: Résumé Mise en application de la théorie d'endochrones au niveau de la roche saline A partir de la théorie d'endochrones, l'on développe une loi des matières pouvant décrire le comportement de la roche saline. Dans cette optique, l'on présente les conceptions de base de cette théorie générale, telles qu'elles ont été développées par Valanis pour les métaux et par Bazant-Bhat pour le béton. Le comportement de déformation de la roche saline, caractérisé par une tendance marquée à ramper, est explicité et décrit à l'aide d'un modèle rhéologique. Le modèle rhéologique sert à la détermination des fonctions et constantes de matières, se trouvant dans la formulation d'endochrones. La loi des matières est formulée de facon tensorielle et l'on donne des instructions quant à son application au niveau des ordinateurs.
    Notes: Zusammenfassung Anwendung der Endochronentheorie auf Salzgestein Es wird ein Stoffgesetz auf Grundlage der Endochronentheorie entwickelt, mit dem das Materialverhalten von Salzgestein beschrieben werden kann. Dafür werden die grundlegenden Vorstellungen dieser allgemeinen Theorie vorgestellt, wie sie von Valanis für Metalle und von Bazant-Bhat für Beton entwickelt wurde. Das Verformungsverhalten von Salzgestein, das durch eine ausgeprägte Kriechneigung geprägt ist, wird erläutert und durch ein rheologisches Modell beschrieben. Das rheologische Modell dient zur Bestimmung der in der Endochronenformulierung vorhandenen Materialfunktionen und Materialkonstanten. Das Stoffgesetz wird in tensorieller Weise formuliert, und es werden Hinweise für seinen Einbau in numerische Rechenmodelle gegeben.

    Notes: Abstract Electron attachment to clusters of HCl, H2O, D2O, C2H4(OH)2, NH3, and ND3 is compared. The clusters are produced in a seeded supersonic beam traversing a sustained gas discharge. For the first four moleculesN min=2 is the lowest number of molecules necessary to support a bound negative ion state. A much largerN min and an isotope effect is observed for ammonia,N min(NH3)=35, andN min(ND3)=41.

    Notes: Abstract Negatively charged cluster ions of hydrogen chloride are formed by electron attachment to HCl clusters, which are produced in a seeded supersonic beam traversing a sustained gas discharge. Cluster ions of (HCl) n − , withn=2, and tentatively withn=3 and 4 are observed. Cluster ions like Cl n − , Cl n − (HCl) m , and withAr attached to them are also seen. The relevance to radiation chemistry of HCl if briefly discussed. Atoms evaporating from the hot, thoriated tungsten filament of the glow discharge lead to clusters such as Th n − and its oxides.

    Notes: Abstract In the present study,57Fe is used as a local probe in order to monitor both the development of the Mn moment and its temperature dependence. The different crystal structures present (C15 and C14) were found to only insignificantly influence the hyperfine pattern. Both the simultaneous presence of magnetic and non-magnetic Mn atoms and the specific easy axis of magnetization in a given compound is found to lead to the occurrence of additional subspectra. Within the Mössbauer effect time window, no substantial magnetic correlations could be detected aboveT C.

    Notes: Summary The hydration of silicate glasses results in the formation of a layer which is depleted in alkali oxides. It is still unknown which of the species H+, H3O+ or H2O diffuses into the glass. In order to clarify the exchange mechanism in particular for reaction times less than 1 h, specimens of a model glass were leached in H2O, D2O, H2 18O and D2 18O. The hydrated layers were analyzed by means of NPB-SIMS, a method using neutral atoms as primary particles. The results indicate significant deviations from long-term leaching kinetics. From the 18O depth profiles it is clear that an oxygen species interdiffuses with sodium ions.

    Notes: Summary  Unseasonably cold weather episodes have the potential to cause dislocation to many aspects of society, regardless of the season in which they occur. In this work we devise a method for quantitatively identifying extreme cold events in such a way that it is not biased to the winter season (as is usual in most other studies). We have applied this method to the daily maximum temperatures (over the period January 1972 to June 1991) in the southern Australian cities of Melbourne and Perth. We identify 10 cold events in winter and summer for the cities. Analyses were performed to determine the synoptic environment in which these events occurred. The most common synoptic type in these samples was the ‘classic’, which is characterised by, amongst other factors, the passage of a cold front over the city on the day of the outbreak, and the transport of air from subantarctic latitudes. Melbourne recorded five such events in summer and six in winter, while seven and eight occurred in the two seasons for Perth. The circulation features and characteristics of other synoptic types identified with these episodes is also examined. The mean synoptic anomalies which are coincident with these cold events are analysed. For both cities and seasons there is a ‘high-low’ anomalous dipole in the regional MSLP pattern, with the high located in the ‘upstream’ quadrant from the anomalous cyclone. Having said this, the relative importance of the two features of the dipole in being associated with the cold event strongly depended on the city and season under consideration. The research shows that the regional structures associated with cold events in Melbourne and Perth bear some similarity, but also display a number of significant differences. These differences are associated partly with the different climatological and synoptic settings in which these cities find themselves, and the nature of their seasonality.
