We report first principle numerical study of domain wall (DW) depinning in two-dimensional magnetic film, which is modeled by 2D random-field Ising system with the dipole-dipole interaction. We observe nonconventional activation-type motion of DW and reveal the fractal structure of DW near the depinning transition. We determine scaling functions describing critical dynamics near the transition ...

thermal rearrangement of 7,7-dichloro-[a,c]-dibenzo-[4,1,0]-bicycloheptane (1) to 5,6-dichloro-5hdibenzo-[a,c]-cycloheptene (2) was studied in the solid phase and in solvents with different polarities. thefirst-order constants at various temperatures for the rearrangement process were evaluated from theabsorption time data. the activation parameters for this rearrangement were obtained from the...

The electrical conductivity of LiCl-GdCl3 molten systems with the gadolinium chloride additions ranging from 0 to 23 mol% was measured depending on both temperature and concentration GdCl3. molar GdCl3-LiCl system is calculated taking into account assumption additivity volume mixture. obtained dependencies can be approximated by Arrhenius-type equation. effective activation energy Ea increased ...

This study has modeled the rheological behavior of thermosonic extracted pink-fleshed guava, pink-fleshed pomelo, and soursop juice concentrates at different concentrations and temperatures. The effects of concentration on consistency coefficient (K) and flow behavior index (n) of the fruit juice concentrates was modeled using a master curve which utilized the concentration-temperature shifting...

1. The effect of temperature on the photosensory latent period in Pholas dactylus is accurately described by the Arrhenius equation when micro = 18,300. 2. The adequacy of this equation has already been found for two other photosensitive animals, Mya and Ciona, which are very similar in behavior to Pholas. The value of micro is different for each of the three species studied. 3. This is taken t...

The removal of radionuclides from the primary coolant system nuclear power plants occurs with dissolution corrosion metal oxide layers deposited radionuclides. Kinetic experiments were conducted a synthetic magnetite specimen in form thin plate using an aqueous solution oxalic acid as reducing agent. effects concentration and temperature investigated on kinetics reductive specimen. In particula...

The aim of the present work was to evaluate with different statistical criteria the suitability of nine equations for describing and optimizing the simultaneous effect of temperature and pH on glucanex activity using two characteristic polysaccharides (curdlan and laminarin) as substrates. The most satisfactory solutions were found with an empirical equation constituted with parameters of pract...

We consider two-dimensional overdamped double-well systems perturbed by white noise. In the weak-noise limit the most probable fluctuational path leading from either point attractor to the separatrix (the most probable escape path, or MPEP} must terminate on the saddle between the two wells. However, as the parameters of a symmetric double-well system are varied, a unique MPEP may bifurcate int...
