Few-body insights of multiquark exotic hadrons

2018

In this contribution we discuss the adequate treatment of the $4-$ and $5-$body dynamics within a constituent quark framework. We stress that the variational and Born-Oppenheimer approximations give energies rather close to the exact ones, while the diquark approximation might be rather misleading. Hall-Post inequalities provide very useful lower bounds that exclude possible stable states for some mass ratios and color wave functions.

Oscillatory periodic pattern dynamics in hyperbolic reaction-advection-diffusion models

2022

In this work we consider a quite general class of two-species hyperbolic reaction-advection-diffusion system with the main aim of elucidating the role played by inertial effects in the dynamics of oscillatory periodic patterns. To this aim, first, we use linear stability analysis techniques to deduce the conditions under which wave (or oscillatory Turing) instability takes place. Then, we apply multiple-scale weakly nonlinear analysis to determine the equation which rules the spatiotemporal evolution of pattern amplitude close to criticality. This investigation leads to a cubic complex Ginzburg-Landau (CCGL) equation which, owing to the functional dependence of the coefficients here involve…

Effect of Boron Doping on the Wear Behavior of the Growth and Nucleation Surfaces of Micro- and Nanocrystalline Diamond Films

2016

B-doped diamond has become the ultimate material for applications in the field of microelectromechanical systems (MEMS), which require both highly wear resistant and electrically conductive diamond films and microstructures. Despite the extensive research of the tribological properties of undoped diamond, to date there is very limited knowledge of the wear properties of highly B-doped diamond. Therefore, in this work a comprehensive investigation of the wear behavior of highly B-doped diamond is presented. Reciprocating sliding tests are performed on micro- and nanocrystalline diamond (MCD, NCD) films with varying B-doping levels and thicknesses. We demonstrate a linear dependency of the we…

Kuvasta valoon : lavastettava valokuva menetelmänä turvallisuuden paikkakokemukseen

2015

Käsittelen tutkimuksessani itse kehittämäni lavastettavan valokuvan mahdollisuuksia taidekasvatusmenetelmänä. Menetelmälleni ominaista on, että se hyödyntää siirto-objektia, eli trasitionaaliobjektia kuvan päähenkilönä, jonka kautta teemaan perehdytään. Menetelmälleni on erityistä se, että ryhmääni osallistuva kuvaaja pysyy koko ajan kameran takana ja saa päättää itse kuvaan kuuluvista symbolisista elementeistä. Kuvasta valoon -projektin aikana olen taiteilijana itse määrittänyt transitionaaliobjektiksi mallinuken jalat, jotka aseteltiin jokaiseen paikkakuvaan. Tutkimuksesnäkökulmassani perehdyn raportoimaan saamistani tuloksista työpajan aikana, suhteuttamaan omaa tutkimustani suhteessa mu…

Symbols of fear in the studies of drawings by Polish and Turkish children

2021

The authors present results of their studies dealing with symbols of fear identified in drawings made by Polish and Turkish children. The studies consisted in comparing results with regard to the categories and content of symbols recognized in the drawings presented by younger school-age children of the two nationalities. For the needs of the comparative analysis the following questions were formulated: In what way did the children present their fears in their drawings? How can the similarities in the symbols of fear presented in the drawings by Polish and Turkish children be interpreted? What do the observed differences testify to? Comparison of the symbols of fear allowed recognizing the …

Statistical Approximation of Fourier Transform-IR Spectroscopy Data for Zinc White Pigment from Twentieth-Century Russian Paintings

2017

We present a statistical model for approximation of experimental Fourier transform-IR spectroscopy (FTIR) data for paint samples from paintings of different ages. The model utilizes random variations in some parameters (initial ageing rate, degree of change in ageing rate and time at which the change occurs). We determine the parameters characterizing variation in the paint composition and the storage conditions for the paintings. The numerical calculation is qualitatively consistent with the experimental data. In the proposed model, changes in the initial composition of the paint and the storage conditions make about the same contribution to the experimentally observed scatter in the data …
