Influence of synthesis parameters on the structure of boehmite sol particles
(Powder Technology, 2003)
Influence of the type and amount of acid, used for aluminium hydroxide peptization, on the crystallinity and specific surface area of the dispersed phase of boehmite sols as well as the pH of sols, was investigated. The ...
Dosimetric characteristics of tissue equivalent thermoluminescent solid TL detectors based on lithium borate
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2001)
This paper presents the main dosimetric characteristics of newly prepared, complete tissue-equivalent thermoluminescent dosimeters Li2B4O7:Cu,In, and Li2B4O7:Cu, in the form of sintered pellets. The dosimetric characteristics ...
Dynamical symmetry breaking and the Nambu-Goldstone theorem in the Gaussian wave functional approximation
(Journal of Mathematical Physics, 2003)
We analyze the group-theoretical ramifications of the Nambu-Goldstone (NG) theorem in the self-consistent relativistic variational Gaussian wave functional approximation to spinless field theories. In an illustrative example ...
Light hadron spectra in the constituent quark model with the Kobayashi-Kondo-Maskawa-t Hooft effective U-A(1) symmetry breaking interaction
(Annals of Physics, 2006)
We make a critical comparison of several versions of instanton-induced interactions present in the literature, all based on ITEP groups extension to three colours and flavours of t Hoofts effective lagrangian, with the ...
Elevated plasma levels of transforming growth factor-beta(1) (TGF-beta(1)) in patients with advanced breast cancer: association with disease progression
(European Journal of Cancer, 2003)
We examined the association between an elevated plasma TGF-beta(1) level and the disease progression of advanced breast cancer (BC) patients (n = 44). TGF-beta(1) levels were detected by an enzyme-linked immunosorbent assay ...
Design of the central region in the Warsaw K-160 cyclotron
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2001)
This paper describes the design of the central region for h=2 and 3 modes of acceleration in the Warsaw K-160 cyclotron. The central region is unique and compatible with the two above-mentioned harmonic modes of operation. ...
Thermal and mechanical properties of cross-linked and uncross-linked linear low-density polyethylene-wax blends
(Polymer Degradation and Stability, 2003)
The influence of the wax content and different concentrations of the crosslinking agent on the thermal and mechanical properties of linear low-density polyethylene-wax blends has been investigated. It was found that an ...
Rapid synthesis of LiCr0.15Mn1.85O4 by glycine-nitrate method
(Solid State Ionics, 2006)
LiCr0.15Mn1.85O4 spinel has been successfully synthesized by glycine-nitrate method (GNM). The presence of pure spinel phase was confirmed by long term XRPD measurements and the Rietveld structural refinement. Lattice ...
Digital gamma-ray spectroscopy based on FPGA technology
(Nuclear Instruments and Methods in Physics Research. Section A: Accelerators, Spectrometers, Detectors, and Associated Equipment, 2002)
A digital pulse processing system convenient for high rate gamma-ray spectroscopy with NaI(Tl) detectors has been designed. The new programmable logic device has been used for implementation of dedicated high-speed pulse ...
Thermal conductivity and thermal diffusivity of selected oxide single crystals
(Journal of Materials Research, 2001)
Values for the thermal conductivity kappa and the thermal diffusivity D of four oxide single crystals were obtained. Near room temperature, the values for kappa (W cm(-1) K-1) and D (cm(2) s(-1)) are as follows: LaAlO3, ...
