    Description / Table of Contents: Zusammenfassung An drei Kreuzungsreihen von Sorten unterschiedlicher Hülsenfarbe (schokoladenbraun, rostrot, grün mit schokoladenbraunen Streifen und grün mit rostroten Streifen) wurde die Vererbung dieses Merkmals bei der Straucherbse (Cajanus cajan (L.) Millsp.) untersucht. Für das Auftreten der schokoladenbraunen Hülsenfarbe ist das GenL verantwortlich,L r, ein bisher unbekanntes Allelomorph vonL, für die rostrote Farbe, während das GenD die Verteilung der Farbe steuert.L ist vollständig dominant überL r undD unvollständig dominant überd. Auf Grund der gemachten Feststellungen werden die Genotypen für die einzelnen Phänotypen angegeben.
    Notes: Summary From three sets of crosses involving the phenotypes chocolate, red oxide, green with chocolate streaks and green with red oxide streaks, the action of the genes governing the phenotypes of the pods ofCajanus cajan (L.) Millsp. has been proposed. GeneL controls production of chocolate colour,L r an allelomorph ofL hitherto unreported, controls production of red oxide colour and geneD controls distribution of this colour. As regards inheritance of these two genes, the relationships betweenL andL r isL〉L r andD is incompletely dominant overd. The genotypes of the different phenotypes have been presented.

    Notes: Summary Various alterations in Giemsa banding technique have been introduced to observe their influence on band formations in M-chromosome of Vicia faba root tip dividing cells. With the introduction of some minor alterations in the technique, revelation of a large number of classes of constitutive heterochromatin has been made possible. Apparently such Giemsa banding pattern is comparable to the ones observed in a routine way amongst mammalian chromosomes.

    Regional metamorphism of pelitic rocks around Kandra, Singhbhum, Bihar (1967)
    Springer
    Contributions to mineralogy and petrology 16 (1967), S. 210-232 
    Details
    ISSN: 1432-0967
    Source: Springer Online Journal Archives 1860-2000
    Topics: Geosciences
    Notes: Abstract A suite of pelitic rocks around Kandra, Singhbhum District, Bihar, displays a metamorphic gradient registered by the index minerals chlorite, biotite, garnet, staurolite and sillimanite in a Barrovian sequence. Metamorphism was by and large coeval with folding movements, and correlating the internal fabric of minerals and deformational characters, a regular sequence of the index minerals is derived. It is argued that the chronological order by itself is not sufficient to prove that metamorphism was progressive in time. Among the index minerals, garnet appears to have formed by the reaction chlorite+biotitea+quartz ⇌ garnet+biotiteb+H2O. For the origin of sillimanite, a new reaction, 3 staurolite+muscovite+quartz=7 sillimanite+biotite+3H2O, is suggested on the basis of significant textural features. Textural and petrological indications regarding the formation of staurolite are in discordance. Staurolite was either derived from the biotite zone phases, or should be taken to have formed, against textural evidences, from chloritoids of the garnet zone. Graphical analysis of the assemblages by Thompson's ‘AFM’ projection reveals that chlorite and staurolite are excess phases owing to retrogression and incomplete reaction. Shifting of apices of triangular fields and intersection of garnet-biotite tie lines within a zone can be satisfactorily explained in terms of extra components CaO and MnO or their ratios. It is pointed out that if MgO/(MgO + FeO) between two phases show a linear relation, their tie lines will be concurrent on the AF side of the projection, the point of concurrence reflecting equilibrium and temperature of recrystallisation.

    Formation of chiasmata in the synchronous meiotic cycle of Lilium longiflorum (1977)

    Notes: Abstract The results of treatment of meiotic cells of Lilium longiflorum by cycloheximide at the time of chiasma initiation and formation suggest that in the sequential phases of nuclear development, complete chiasma suppression resulting in achiasmate cells is attained prior to a quantitative reduction of chiasma frequency. Reduction of chiasma frequency and complete suppression are believed to be based on two different mechanisms.

    Structural Characterization of Titanium Nitride Coatings on AISI M2 Steel (2007)
    s.l. ; Stafa-Zurich, Switzerland

    ISSN: 1662-9752
    Source: Scientific.Net: Materials Science & Technology / Trans Tech Publications Archiv 1984-2008

    Notes: In this work, some surface properties of AISI M2 steel were improved by a thermoreactivedeposition process. Gas nitriding was realized on AISI M2 steel at 550°C for 2 h in anammoniac atmosphere and then, titanizing treatment performed on pre-nitrided steel in the powdermixture consisting of ferro-titanium, ammonium chloride and alumina at 1000°C for 1-4 h.Structural characterization of titanium nitride layer formed on the surface of AISI M2 steel wascarried out by using optical microscopy, scanning electron microscopy, electron microprobe and Xraydiffraction (XRD) analysis. The hardness measurements of titanium nitride layer wereconducted under 10 g loads by using Vickers microhardness indenter. Structural analysis studiesshowed that titanium nitride layers formed on the AISI M2 steel samples were smooth, compact andhomogeneous. XRD analysis show that the coating layer formed on the steel samples includes TiN,Fe6Mo7N2, C0.7N0.3Ti, C0.3N0.7Ti and V2N phases. The hardness of titanium nitride layers formed onthe steel samples is between 2040±186 and 2418±291 HV0.01. The thickness of titanium nitridelayer formed on the steel samples ranged from 3.86±0.43 9m to 6.13±0.47 9m, depending ontreatment time
