Microscopic investigations of Shisr 007 meteorite
(Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2009)
Elemental composition, mineral composition and microstructure of Shisr 007 meteorite found in 2001 have been studied by analytical electron microscopy. It was established that the main meteorite minerals: olivines, pyroxenes, ...
The effect of contrasting selected graphical elements of a web page on information retrieval time
(Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2009)
As online presence plays an increasingly important role in corporate success, the high usability of a company’s website becomes one of its most valuable assets. The time required to reach the needed information, which plays ...
Dielectric relaxation modes in liquid crystalline mixture
(Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2009)
Mixture of two liquid crystalline compounds (which do not exhibit antiferroelectric or ferrielectric phase separately) shows ferrielectric phase in a broad temperature range. The dielectric spectroscopy technique was used ...
Numerical investigation of deformations of planar flexoelectric nematic layers containing ions
(Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2008)
Deformations of planar nematic layers of conducting nematic liquid crystal possessing flexoelectric properties and subjected to external d.c. voltage were studied numerically. Various kinds of electrodes, from strongly ...

Effect of temperature on the refractive index and Kerr effect of the transformer oil Nynas Nytro Taurus
(Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2009)
The temperature dependence of refractive index of the mineral transformer oil Nynas Nytro Taurus within the range 278-385K is determined. Changes with temperature in the quadratic electrooptic response of the oil are ...
Activation processes for two chosen aromatic hydrocarbon materials
(Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2009)
The activation process and the transport process for electrons in the tetracene layers and holes in the p-quaterphenyl layers is considered. Obtained results may suggests the hopping transport through the localized states ...
Numerical studies of significance of anchoring strength energy for behaviour of flexoelectric homeotropic nematic layer subjected to DC electric field
(Wydawnictwo Politechniki ŁódzkiejLodz University of Technology. Press, 2009)
Elastic deformations of homeotropic nematic liquid crystal layers subjected to a d.c. electric field were studied numerically. The flexoelectric properties of the nematic material and the presence of ionic space charge ...
