  • Пути разрешения кризиса идентичности инженера-технолога в производственной среде 
    КОНДРАТЕНКО, Ольга; ИРОВАН, Марчела (Asociaţia Tinerilor Cercetători din Moldova „PRO-Ştiinţa”, 2009)
    Связывая кризис идентичности с процессом развития личности инженера-технолога, можно предположить, что подобные кризисы не только неизбежны, но и по-своему необходимы для профессионального самоутверждения личности в ...
  • Use of non-traditional methods of constructing garments with three-dimensional elements

  • The property of universality for some monoid algebras over non-commutative rings 
    COJUHARI, Elena P. (Institutul de Matematică şi Informatică al AŞM, 2006)
    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 derivations of the ring A. A monoid algebra of G ...
  • 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 ...
  • An abstract approach to the study of derivation mappings on non-commutative rings 
    COJUHARI, Elena P. (Institutul de Matematică şi Informatică al AŞM, 2007)
    An abstract approach to the study of derivation mappings on non-commutative rings is undertaken. These mappings are indexed by elements of multiplicative monoid. We describe completely the derivation mappings in the case ...

    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 ...
