Opis:
We present new experimental evidence indicating the importance of magnetic field component of microwave field (f=9.4 GHz) for magnetoresistive properties of polycrystalline La$\text{}_{0.7}$Ca$\text{}_{0.3}$MnO$\text{}_{3}$ films. The microwave measurements revealed a different character of the temperature-dependent electrical resistance of polycrystalline La$\text{}_{0.7}$Ca$\text{}_{0.3}$MnO$\text{}_{3}$ films placed in the centre (maximal amplitude of H$\text{}_{10}$ wave vector) and at a narrow wall of the wave-guide (reduced H$\text{}_{10}$ amplitude). Theoretical estimations of the influence of substrate onto distribution of microwave electric and magnetic fields in the waveguide were performed using the finite-difference time-domain method.

Opis:
The paper reviews recent work in the area of high-k dielectrics for application as the gate oxide in advanced MOSFETs. Following a review of relevant dielectric physics, we discuss challenges and issues relating to characterization of the dielectrics, which are compounded by electron trapping phenomena in the microsecond regime. Nearly all practical methods of preparation result in a thin interfacial layer generally of the form SiOx or a mixed oxide between Si and the high-k so that the extraction of the dielectric constant is complicated and values must be qualified by error analysis. The discussion is initially focussed on HfO2 but recognizing the propensity for crystallization of that material at modest temperatures, we discuss and review also, hafnia silicates and aluminates which have the potential for integration into a full CMOS process. The paper is concluded with a perspective on material contenders for the "end of road map" at the 22 nm node.

Opis:
The transition regions of GdSiO/SiOx and HfO2/ SiOx interfaces have been studied with the high-k layers deposited on silicon substrates. The existence of transition regions was verified by medium energy ion scattering (MEIS) data and transmission electron microscopy (TEM). From measurements of thermally stimulated current (TSC), electron states were found in the transition region of the HfO2/SiOx structures, exhibiting instability attributed to the flexible structural molecular network expected to surround the trap volumes. The investigations were focused especially on whether the trap states belong to an agglomeration consisting of a single charge polarity or of a dipole constellation. We found that flat-band voltage shifts of MOS structures, that reach constant values for increasing oxide thickness, cannot be taken as unique evidence for the existence of dipole layers.

Opis:
Artykuł prezentuje proces tworzenia narzędzia do badania oczekiwań doradczych zbudowany na podstawie koncepcji stylów poradnictwa opracowanej przez Bożenę Wojtasik (1997). Badanie pilotażowe przeprowadzono z udziałem 268 uczniów szkół średnich (techników i liceów), w tym 169 chłopców i 99 dziewcząt w wieku od 17 do 20 lat. Analiza psychometryczna narzędzia nie potwierdziła istnienia skal teoretycznych, określonych kategoriami takimi, jak ekspert, informator, leseferysta, konsultant i spolegliwy opiekun oraz wyłoniła dwie nowe kategorie – „Doradca humanistyczny” (10 pozycji, alfa Cronbacha = 0,834) i „Doradca racjonalny” (10 pozycji, alfa Cronbacha = 0,741). Do weryfikacji trafności zewnętrznej testu zastosowano dwa testy osobowości: Kwestionariusz NEO-FFI Costy i McCrae oraz Test Przymiotnikowy ACL Gougha i Heilbruna. Sprawdzono również, że jest on także metodą stabilną w czasie. Opracowano ostateczną wersję kwestionariusza wraz z normalizacją.
The article presents the process of creating a tool for research of counselling expectations based on the concept of counselling styles elaborated by Bożena Wojtasik (1997). The pilot study was done with the help of 268 high school students [technical and liceum (comprehensive)] comprised of 169 boys and 99 girls aged between of 17 – 20. A psychometric analysis of this tool has not confirmed the existence of theoretical scales relating to categories such as expert, informant, laissez-faire, consultant, submissive guardian, but has lead to two new categories – "humanist counsellor" (10positions, Cronbach's alfa = 0,834) and "rational counsellor" (10positions, Cronbach's alfa = 0,741). To verify the adequacy of an external test, two personality tests were used: the NEO-FFI questionnaire by Costy and McCrae and Guough's and Heilbrun's ACL Adjective test. It has also been verified whether the method described is stable over time. A final version of the questionnaire has been prepared along with a normalisation.

Opis:
We report on the X-ray powder diffraction and magnetic measurements of the polycrystalline and the two nanocrystalline samples of $DyMnO_{3}$ compound synthesized at temperatures of 800 and 850°C. All samples at room temperature crystallize in the orthorhombic crystal structure (space group Pnma). The crystal structure parameters determined change only slightly with preparation methods but the average grains size of the nanoparticles determined from X-ray data increases significantly with increasing annealing temperature. Temperature dependence of the magnetic susceptibility indicates the antiferromagnetic order in Dy sublattice at low temperatures.

Opis:
A systematic indoor radon survey in elementary schools of Serbia is underway since 2008. Its current first phase covers all elementary schools in predominantly rural communities of Southern Serbia. The design of the survey, its implementation and the current state of its realization is shortly described. Part of this paper is devoted to discussion of the question if this survey could produce results representative also of the radon concentration in dwellings and of radon exposure of the general population, discussing some statistical aspects of representativity which arose during the work, namely, if the implementation leads to an unbiased estimate of the targeted quantities.

Opis:
In this paper, we propose a new and efficient short signature scheme from the bilinear pairings. Our scheme is constructed by bilinear inverse-square Diffie-Hellman problem (BISDHP) and does not require any special hash function. The exact security proofs are also explained in the random Oracle model. We give the implementation and comparison results of our proposed signature scheme with the signature scheme proposed by Boneh, Lynn, Shacham (BLS) and Zhang, Safavi, Susilo (ZSS). Furthermore, we use this signature scheme to construct a ring signature scheme.

Opis:
The fatty acid methyl esters (FAME's) - in Europe mostly RME *) (Rapeseed methyl ester; Abbreviations see at the end of this paper) - are used in several countries as alternative biogenic Diesel fuels in various blending ratios with fossil fuels (Bxx). Questions arise often about the influences of these biocomponents on the modern exhaust after-treatment systems and especially on the regeneration of Diesel particle filters (DPF). In the present work different regeneration procedures of DPF systems were investigated with biofuels B0, B20 & B100. The tested regeneration procedures were: - passive regenerations: DOC + CSF; CSF alone, - active regenerations: standstill burner; fuel injections & DOC. During each regeneration on-line measurements of limited and unlimited emission components (nanoparticles & FTIR) was conducted. It can be stated that the increased portion of RME in fuel provokes longer time periods to charge the filter with soot. This is due to the lower PM-emissions of the engine, as well as to the higher reactivity and higher SOF-portion of the particle mass from RME. With the passive regeneration system with stronger catalytic activity (DOC + CSF) there is a stronger NO2-production with B100 and due to the NO2-supported oxidation of PM the balance point temperature is approx. 20 centigrade lower, than with B0. For the active regenerations the time courses of emissions and temperatures are closely connected with the chosen regeneration strategy - switching, timing and intensity (of burner, or fuel aerosol generator). A higher portion of biocomponent causes usually a stronger break-down of the instantaneous DPF filtration efficiency during the regeneration procedure - this is an effect of stronger artifact of spontaneous condensation after DPF. In summary there is no negative short term effect of bio-blended-fuels on the investigated regeneration procedures. Some recommendations for a successful long term operation, basing on other works and literature are given at the end of the paper.
