Os sentidos de competência no trabalho: discurso da mídia e discurso acadêmico

open access: yesFilologia e Linguística Portuguesa, 2007
This article aims to deal with the notion of competence in prescriptive discourses related to the theme work. Our object of study is the discourses that speak about the way of behaving at work and of thinking about work.

Polynomial tempered distributions

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
In the article polynomial (nonlinear) analogue of tempered Schwartz distributions is constructed. Generalized operation of differentiation in the space of polynomial generalized functions as well as Fourier-Laplace transformation of such distributions ...

Complete Pathway Refactoring and Combinatorial Biosynthesis of Anthracyclines for Modulation of Histone Eviction and DNA Damage Bioactivities

open access: yesAngewandte Chemie, EarlyView.
A synthetic biology platform was established for the complete refactoring of complex anthracycline biosynthetic pathways in Streptomyces coelicolor using standardized, chemically synthetic DNA parts. This modular construction enabled streamlined combinatorial biosynthesis, yielding novel analogs that decouple DNA damage from chromatin damage (histone ...

On local smooth solutions for the Vlasov equation with the potential of interactions ±r−2

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
For the initial value problem for the Vlasov equation with the potential of interactions ±r−2, we prove the existence and uniqueness of a local solution with values in the Schwartz space S of infinitely differentiable functions rapidly decaying at ...

Access to Unsupported Iminobismuthane and Tetraazabismole Species Enabled by a Rigid and Bulky Organobismuthinidene

open access: yesAngewandte Chemie, EarlyView.
By employing a sterically bulky monocoordinate bismuthinidene, the synthesis and characterization of the first examples of an unsupported iminobismuthane and tetraazabismole was achieved via reactions with organic azides. The corresponding amines could be accessed by reduction, leading to the regeneration of the Bi(I) compound. Hence, we also highlight

Life Values of Today’s Young University Students: Problems of Teacher Education [PDF]

open access: yesARPHA Proceedings, 2019
What makes this research relevant is the changes in the society’s and an individual’s value space, which affect the young the most, as the youth is more dynamic and sensitive to social changes, to changes in the society’s ideology and values.

Further Results on Colombeau Product of Distributions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2013
Results on Colombeau product of distributions and are derived. They are obtained in Colombeau differential algebra of generalized functions that contains the space of Schwartz distributions as a subspace and has a notion of “association” that is a ...

Distributional celestial amplitudes

open access: yesJournal of High Energy Physics
Scattering amplitudes are tempered distributions, which are defined through their action on functions in the Schwartz space S ℝ $$ \mathcal{S}\left(\mathbb{R}\right) $$ by duality.

An embedding of Schwartz distributions in the algebra of asymptotic functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1998
We present a solution of the problem of multiplication of Schwartz distributions by embedding the space of distributions into a differential algebra of generalized functions, called in the paper “asymptotic function,” similar to but different from J.
