Opis:
Computational dosimetry play a significant role in an industrial radiation processing at dose measurements in the product irradiated with electron beams (EB), X-ray and gamma ray from radionuclide sources. Accurate and validated programs for absorbed dose calculations are required for computational dosimetry. The program ModeStEB (modelling of EB processing in a three-dimensional (3D) multilayer flat targets) was designed specially for simulation and optimization of industrial radiation processing, calculation of the 3D absorbed dose distribution within multilayer packages. The package is irradiated with scanned EB on an industrial radiation facility that is based on the pulsed or continuous type of electron accelerators in the electron energy range from 0.1 to 25 MeV. Simulation of EB dose distributions in the multilayer targets was accomplished using the Monte Carlo (MC) method. Experimental verification of MC simulation prediction for EB dose distribution formation in a stack of plates interleaved with polyvinylchloride (PVC) dosimetric films (DF), within a packing box, and irradiated with a scanned 10 MeV EB on a moving conveyer is discussed.

Opis:
A medium−diversity fauna of late Ordovician rhynchonelliformean brachiopods occurs in the Tauken Formation (upper Caradoc–lowermost Ashgill) of north Central Kazakhstan.It demonstrates close similarity to the approximately contemporaneous faunas characteristic of shallow clastic shelves (BA 2–3) of the Chingiz and Chu−Ili ranges (both in Kazakhstan) and South China, but is characterized by a high proportion of endemic new species, including Tetraphalerella bestiubensis sp.nov., Glyptomena kaskolica sp.nov., Dinorthis taukensis sp.nov., Rhynchotrema seletensis sp.nov., and Nalivkinia (Pronalivkinia)zvontsovisp.nov.The abundance of Rhynchotrema is somewhat unusual by comparison with faunas from other Kazakhstanian terranes, where rhynchonellides of the family Ancistrorhynchidae are usually dominant in near−shore biofacies.The occurrence of the atrypides Sulcatospira and early Nalivkinia demonstrates a clear biogeographical linkage with approximately contemporaneous faunas of South China.

Opis:
Thermal expansion Δl/l(T) and magnetostriction λ$\text{}_{∥, ⊥ }$(H,T) in the pulsed magnetic fields H up to 250 kOe were studied in the single La$\text{}_{1-x}$Sr$\text{}_{x}$MnO$\text{}_{3}$ crystals (x=0.1, 0 .125, and 0.15) at temperatures T=10-320 K. Anomalies in the Δl/l (T) curves were observed near a charge (polaron) ordering (T$\text{}_{p}$) and structural transitions between orthorhombic Jahn-Teller distorted O' phase and high temperature orthorhombic (pseudocubic) O$\text{}^{*}$ one (T'$\text{}_{s}$). A noticeable increase in the field-induced magnetostriction λ$\text{}_{∥, ⊥ }$(H) was revealed in the O' phase at T$\text{}_{p}$
