Structural and magnetic properties of amorphous and partly crystallized Fe_{73.5−x}Ce_{x=0,3,5,7}Si_{13.5}B_9Nb_3Cu_1 alloys, were analysed in the temperature ranging from RT to 800 °C with scanning calorimetry and ... -
Badania warstw związków organicznych o właściwościach paramagnetycznych z uwzględnieniem procesu samoorganizacji i badań materiałów biologicznych
(2015)W pracy przedstawiono badania paramagnetycznych rodników nitroksylowych oraz znakowanych spinowo polipeptydów zaadsorbowanych na dobrze zdefiniowanych powierzchniach. Wyniki eksperymentalne zostały uzyskane przy pomocy ... -
Redukcja zakłóceń interferencyjnych w detektorach radiowych Obserwatorium Pierre Auger
(2015)W ciągu ostatnich lat dokonany został ogromny postęp w elektronice, który umożliwił rozwój technik detekcji pęków atmosferycznych, inicjowanych przez cząstki promieniowania kosmicznego. Postęp ten spowodował również, że ... -
Examination of some heavy metal pollution in roadside plants using X-ray spectroscopy
(2015-09-01)PhD thesis of mgr Punsiri Dam-o is dedicated to studies of the heavy metal pollution in samples of biological origin using the X-ray spectroscopy technique. The thesis contains the 156 pages, is preceded by a table of ... -

The observation of ultrahigh energy neutrinos (UHE𝜈�s) has become a priority in experimental astroparticle physics. UHE𝜈�s can be detected with a variety of techniques. In particular, neutrinos can interact in the ... -
Semientwining Structures and Their Applications
(Hindawi Publishing Corporation, 2012-10-31)Semientwining structures are proposed as concepts simpler than entwining structures, yet they are shown to have interesting applications in constructing intertwining operators and braided algebras, lifting functors, ... -
Chiral fermions, massless particles and Poincare covariance
; Kijanka Dec, Agnieszka; ; (Elsevier, 2015-05-19)
The coadjoint orbit method is applied to the construction of Hamiltonian dynamics of massless particles of arbitrary helicity. The unusual transformation properties of canonical variables are interpreted in terms of nonlinear ... -

(2015)W pracy przedstawiono wyniki analizy danych z eksperymentów, w których metodą korelacji kątowych badano jądra 130Ba, 140Sm i 124Cs wyprodukowane z użyciem wiązek ciężkich jonów dostarczonych przez cyklotron U-200P należący ... -
Modification of thin films induced by slow heavy ions analysed with PIXE and SRIM
(Springer, 2015-03-17)In the present work the particle induced X-rays (PIXE) emitted during interaction of inert and active slow heavy (HI) ions with specially prepared thin films were measured. Kinematics of the interaction was simulated ... -
Induced gravity and gauge interactions revisited
(North-Holland, 2009)It has been shown that the primary, old-fashioned idea of Sakharov's induced gravity and gauge interactions, in the “one-loop dominance” version, works astonishingly well yielding phenomenologically reasonable results. As ... -
Quantum gravity stability of isotropy in homogeneous cosmology
(North-Holland, 2011)It has been shown that anisotropy of homogeneous spacetime described by the general Kasner metric can be damped by quantum fluctuations coming from perturbative quantum gravity in one-loop approximation. Also, a formal ... -
Scaling violation and the inelasticity of very high energy proton–proton interactions
(North-Holland, 2011)The pseudorapidity measurements at LHC, although in the central region only, allows us to perform preliminary tests of the multiparticle production extrapolation formula inspired by the analysis of recent cosmic ray data. ... -
Hidden Lorentz symmetry of the Hořava–Lifshitz gravity
(North-Holland, 2014)In this Letter it is shown that the Hořava–Lifshitz gravity theory admits Lorentz symmetry preserving preferred global time foliation of the spacetime. -
Perturbative quantum damping of cosmological expansion
(North-Holland, 2014)Perturbative quantum gravity in the framework of the Schwinger–Keldysh formalism is applied to compute lowest-order corrections to expansion of the Universe described in terms of the spatially flat Friedman–Lemaître–Robe ... -
Conformal Newton–Hooke symmetry of Pais–Uhlenbeck oscillator
(North-Holland, 2014)It is demonstrated that the Pais–Uhlenbeck oscillator in arbitrary dimension enjoys the l -conformal Newton–Hooke symmetry provided frequencies of oscillation form the arithmetic sequence ωk=(2k−1)ω1, where k=1,…,n, and ... -
“Isochronic” dynamical systems and nullification of amplitudes
(North-Holland, 2003)We construct the set of theories which share the property that the tree-level threshold amplitudes nullify even if both initial and final states contain the same type of particles. The origin of this phenomenon lies in ... -
On the triviality of higher-derivative theories
(North-Holland, 2012)The higher-derivative theories with degenerate frequencies exhibit BRST symmetry [V.O. Rivelles, Phys. Lett. B 577 (2003) 147]. In the present Letter meaning of BRST-invariance condition is analyzed. The BRST symmetry is ...
