  • Skew ring extensions and generalized monoid rings 
    COJUHARI, E. P.; GARDNER, B. J. (Springer Nature Switzerland, 2018)
    A D-structure on a ring A with identity is a family of self-mappings indexed by the elements of a monoid G and subject to a long list of rather natural conditions. The mappings are used to define a generalization of the ...
  • Radicals and idempotents I 
    COJUHARI, E. P.; GARDNER, B. J. (Taylor & Francis, 2021)
    A corner of a ring A is a subring eAe, where e is an idempotent. Radical and semi-simple classes which are hereditary for corners and cases where the radical of a ring contains all radical corners are studied.
  • Preservation of radicals by generalizations of derivations 
    COJUHARI, E. P.; GARDNER, B. J. (Institutul de Matematică şi Informatică al AŞM, 2017)
    By results of Anderson and Slin’ko, derivations preserve the locally nilpotent and nil radicals of algebras over a field of characteristic 0. There is also a well known and elementary result that derivations preserve ...
  • Monoid algebras over non-commutative rings 
    COJUHARI, E. P. (Abdullah HARMANCI, 2007)
    We define on an arbitrary ring A a family of mappings (σx,y) subscripted with elements of a multiplicative monoid G. The assigned properties allow to call these mappings as derivations of the ring A. Beside the general ...
  • Generalized higher derivations 
    COJUHARI, E. P.; GARDNER, B. J. (Australian Mathematical Publishing Association Inc., 2012)
    A type of generalized higher derivation consisting of a collection of self-mappings of a ring associated with a monoid, and here called a D-structure, is studied. Such structures were previously used to define various kinds ...
  • Further Remarks on Elementary Radicals and Associated Filters of Ideals 
    COJUHARI, E. P.; GARDNER, B. J. (Australian Mathematical Publishing Association Inc., 2021)
    Ryabukhin showed that there is a correspondence between elementary radical classes of rings and certain filters of ideals of the free ring on one generator, analogous to the Gabriel correspondence between torsion classes ...

  • Sorption of Cr(III)-containing cations on strongly basic anion exchangers 
    DRUTSA, Raisa; GUTSANU, V.; RUSU, V. (Wiley Periodicals, 2006)
    It is shown that strongly basic anion exchangers AV-17 and Varion-AD in definite conditions are able to retain Cr(III)-containing ions from Cr(III) sulfate solution. It is found that the sorption of Cr(III)-containing ions ...

    Simulatoarele metrologice de impedanţă (SIM) în coordonate Carteziene prezintă circuite, care asigură reproducerea impedanţelor de referinţă cu caracter diferit, utilizate la măsurarea impedanţelor. Impedanţa reprodusă de ...
  • The comparative analysis of map projections for the Republic of Moldova territory 
    CHIRIAC, V.; VLASENCO, A. (Видавництво Львівської політехніки, 2016)
    Starting from 2001 a new reference system MOLDREF99 based on European Terrestrial Reference System (ETRS89) and Transversal Mercator for Moldova (TMM) map projection was established to provide large scale mapping from 1:500 ...
  • Study of the inclinometer calibration method using geodetic measurements 
    IACOB, Mihail; CHIRIAC, Vasile; CICLICCI, Vladimir (Editura Aeternitas, 2018)
    The inclinometer is used for small-angle measurement and can be fixed on the radio-communication tower to obtain changes relative to the construction’s vertical plane. The real inclination of the tower can be calculated ...

  • Relation between chemical composition of oak wood used in cooperage and sensory perception of model extracts 
    PRIDA, Andrei; HEYMANN, Hildegarde; BALANUTA, Anatol; PUECH, Jean-Louis (John Wiley & Sons, Inc., 2009)
    Oak wood samples (140) were analysed both chemically (using gas chromatography/mass spectrometry after extraction with dichloromethane) and using sensory descriptive analysis of oak-extracted model wine solutions.
  • Impactul originei lemnului de stejar asupra indicilor specifici ai vinului roşu
