    Aquifer Response in the Ultramafic Field Area of Sukhinda Valley — Orissa (India) (1980)
    Oxford, UK : Blackwell Publishing Ltd
    Ground water 18 (1980), S. 0 
    Details
    ISSN: 1745-6584

    Topics: Energy, Environment Protection, Nuclear Power Engineering , Geosciences
    Notes: Analysis of a long-duration aquifer performance test utilizing a well near Kansa in the Sukhinda ultramafic body of the Cuttack District in Orissa has demonstrated that nonequilibrium formulae can be applied to hard-rock regions depending upon the stage of hydrogeological regime and the vertical leakage in the system. Graphical analysis of test results under nonsteady and steady-state conditions have helped in understanding the behavior of aquifers and their characteristics. A comparative examination of results obtained by different methods and careful insight has helped in delineating the boundary conditions, long-term withdrawal effects and well spacing problems in the present area, and this approach could be applied in similar well fields.

    Role of differential shrinkage and creep in time dependent behaviour of composite members (1977)
    Springer
    Materials and structures 10 (1977), S. 79-84

    Description / Table of Contents: Résumé Le comportement dans le temps des poutres de béton précontraint composite dépend du retrait différentiel et du fluage des bétons de l'âme et du tablier, sans compter d'autres paramètres, tels que la relaxation de l'acier, la présence d'acier non tendu et d'acier de compression etc. Cette étude a séparé les effets du retrait différential et du fluage de ceux des autres paramètres qui leur sont associés, au moyen d'un essai de charge de longue durée sur un prisme de béton composite, et l'on décrit aussi une méthode d'analyse dite «méthode de rigidité variable» pour en prédire le comportement: Les contraintes et déformations du prisme composite constitué de deux bétons différents et soumis à une charge de longue durée sont déterminées analytiquement. Les caractéristiques de fluage et de retrait des deux bétons sont fournies par des expériences préliminaires selon les recommandations du C.E.B. et de l'A.C.I. Les résultats analytiques concordent bien avec les valeurs expérimentales obtenues sur trois prismes de béton chargés durant 160 jours ce qui corrobore également la méthode analytique utilisée.
    Notes: Abstract The time dependent behaviour of composite prestressed concrete beams depends upon the presence of differential shrinkage and creep of the concretes of web and deck, in addition to other parameters, such as relaxation of steel, presence of untensioned steel, and compression steel etc. In view of the interrelationships among these various parameters, it is proposed to isolate the effects of differential shrinkage and creep from other parameters by studying the behaviour of composite prisms under sustained load. The stresses and strains in composite prisms made up of two different concretes under sustained load are analytically determined using varying stiffness method of analysis. Creep and shrinkage characteristics of the two concretes are obtained from preliminary experiments using C.E.B. and also A.C.I. recommendations. The analytical results are found to be in close agreement with the experimental values obtained on three concrete prisms under sustained load for 160 days and thus also confirm the method of analysis.

    In vitro hybridization in an incompatible cross Nicotiana glutinosa X Nicotiana megalosiphon (1985)
    Springer
    Theoretical and applied genetics 71 (1985), S. 545-549 
    Details
    ISSN: 1432-2242
    Keywords: In vitro hybridization ; Phenotypic variation ; Chromosomal range ; Functional disharmony
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary Using conventional techniques interspecific hybridization between N. glutinosa (2n=24) and N. megalosiphon (2n=40) results in failure while the reciprocal is successful. Attempts were made here to obtain an F1 hybrid of N. glutinosa X N. megalosiphon by embryo rescue. These reciprocal hybrids resembled each other in their phenotypic and chromosomal behaviour, i.e. there is broad spectrum of phenotypic variation coupled to chromosomal range from 2n-28 to 32. This may be due to the functional disharmony between chromosome sets of two unrelated species resulting in the elimination of chromosomes.

    Genotypes and their response to in vitro production of haploids in F1 lines of Nicotiana tabacum (1985)
    Springer
    Theoretical and applied genetics 70 (1985), S. 225-226 
    Details
    ISSN: 1432-2242
    Keywords: Anther culture ; Nicotiana ; Haploids ; Genotype ; Mutants
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary The present article reports on pollen embryogenesis resulting in haploid plants in 14 different F1 lines of Nicotiana tabacum. The response for pollen embryogenesis was high in cultures where the F1 lines were derived from mutants. Present observations are in agreement with previous reports on Secale cereale where one of the parents is from a mutant MII. These observations indicate that plant genotype is the main factor for differences in the induction of pollen embryogenesis.

    ISSN: 1573-0824
    Keywords: Multidimensional systems ; transfer functions ; digital filters ; separable numerator ; denominator ; blocks ; configuration ; optimum realization
    Source: Springer Online Journal Archives 1860-2000
    Topics: Electrical Engineering, Measurement and Control Technology
    Notes: Abstract In this paper a straightforward z-domain procedure for realizing multidimensional transfer functions with either numerator or denominator polynomial separable is presented. This procedure yields structures with minimum number of multipliers. It is shown that the number of delay elements can be reduced by selecting the optimum values for certain parameters. To facilitate this theorems that are applicable for some special cases are presented.
