Opis:
In this paper we present the results of ESR and photo-ESR measurements on YAlO$\text{}_{3}$(YAP) single crystals and powder samples doped purposely with about 1 at.% Nd$\text{}^{3+}$ and undoped crystals in which Er$\text{}^{3+}$ was observed as residual dopant. The ESR measurements were carried out at X-band spectrometer in 4-300 K temperature range. The photo-ESR was performed at 5 K using a mercury arc lamp. For the Nd$\text{}^{3+}$ doped crystals the intensity of ESR signal decreased about 2 times during illumination conditions. Moreover, the calculations of the g tensor and A hyperfine structure parameters for Nd$\text{}^{3+}$ and Er$\text{}^{3+}$ were carried out.

Opis:
We studied lateral silicon p-i-n junctions, doped with phosphorus and boron, regarding charge sensing feasibility. In order to examine the detection capabilities and underlying mechanism, we used in a complementary way two measurement techniques. First, we employed a semiconductor parameter analyzer to measure I−V characteristics at a low temperature, for reverse and forward bias conditions. In both regimes, we systematically detected Random Telegraph Signal. Secondly, using a Low Temperature Kelvin Probe Force Microscope, we measured surface electronic potentials. Both p-i-n junction interfaces, p-i and i-n, were observed as regions of a dynamic behaviour, with characteristic time-dependent electronic potential fluctuations. Those fluctuations are due to single charge capture/emission events. We found analytically that the obtained data could be explained by a model of two-dimensional p-n junction and phosphorus-boron interaction at the edge of depletion region. The results of complementary measurements and analysis presented in this research, supported also by the previous reports, provide fundamental insight into the charge sensing mechanism utilizing emergence of individual dopants.

Opis:
New results concerning paramagnetic defects in SrLaAlO$\text{}_{4}$ and SrLaGaO$\text{}_{4}$ high-T$\text{}_{c}$ substrates connected with unavoidable impurity Fe$\text{}^{3+}$ are reported. The identification was checked by measuring the spectra in SrLaAlO$\text{}_{4}$ crystals intentionally doped with 0.5 at.% Fe. Angular dependences of three lines were distinguished at X-band frequency in the temperature range from 4 K to 300 K. We attribute these lines to the transitions inside the doublets ±1/2, and "forbidden" doublets ±3/2, ±5/2, respectively. By diagonalization of spin-Hamiltonian, parameters |D| > 1.2 cm$\text{}^{-1}$, |E| ≈ 0.1 cm$\text{}^{-1}$ and g$\text{}_{x}$=g$\text{}_{y}$=g$\text{}_{z}$= 1.987(13) for SrLaAlO$\text{}_{4}$ and SrLaGaO$\text{}_{4}$ were calculated and within the margin of error they were of the same value.

The effect of annealing SrLaAlO$\text{}_{4}$ (SLA) and SrLaGaO$\text{}_{4}$ (SLG) crystals in oxidizing and reducing atmospheres in the temperature range of 950°C-1300°C was investigated. Three kinds of anisotropic defects D$\text{}_{1}$, D$\text{}_{2}$, and E at the temperature range of 4-300 K were found. By diagonalization of orthorhombic spin-Hamiltonian parameters: |D|=0.0541(10) cm$\text{}^{-1}$, |E|=0.0108(10) cm$\text{}^{-1}$, g$\text{}_{∥}$=0.883(5), and g$\text{}_{⊥ }$=1.922(5) for D$\text{}_{1}$ defects for SLG and SLA were calculated and they had the same values within the margin of error.

Opis:
Accurate reproduction of colors requires methods of calibrating a digital camera. In case of a camera which employs filters with spectral characteristics deduced from the color matching functions, a set of reference calibration colors must be used to obtain a conversion matrix between raw data from imaging sensor and colorimetric tristimulus values XYZ, from which the output signal is formed. The XYZ camera used for testing of the presented calibration me thod is capable of acquiring colors accurately in the whole vision gamut due to its filters. However, the well-established color references, like the Macbeth Chart or other similar color checkers, are not entirely sufficient for the calibration due to their enclosure in smaller color gamut (HDTV - High Definition Television) than the whole vision gamut. The presented method is based on choosing the calibration colors by their spectral distributions, which are related with the spectral characteristics of the filters. The obtained result was found to be ?E=1.57 for the designed colors.

Opis:
The paper presents results of numerical analysis of AFM images of a surface of sandblasted Ti6Al7Nb alloys before and after wet etching procedure usually used for preparing commercially viable dental implants. Obtained results demonstrate that etching procedure efficiently cleans the implants as it leaves almost pure Ti-Al-Nb surface with trace amounts of alkali metals and increased hydrophobicity. Apart of that, it turned out that simple statistical measures of the height variations (root mean square roughness) only slightly change upon the treatment procedure, especially for scan lengths below 20 μm. On the other hand, correlation analysis exhibits bifractal surface patterns composed of regular residues left on otherwise helical ridges of the base material. Etching leaves its fingerprint in fractal dimension, but not in the corner frequency.

Opis:
Single electron devices (SEDs) are candidates to become a keystone of future electronics. They are very attractive due to low power consumption, small size or high operating speed. It is even possible to assure compatibility with present CMOS technology when natural potential fluctuations introduced by dopant atoms are used to create quantum dots (QD). However, the main problem of this approach is due to the randomness of dopant distribution which is characteristic for conventional doping techniques. This leads to scattered characteristics of the devices, which precludes from using them in the circuits. In these work we approach the problem of correlating the distribution of QD's with the device characteristics. For that, we investigate with a Kelvin probe force microscope (KFM) the surface potential of Si nanodevice channel in order to understand the potential landscape. Results reveal the features ascribable to individual dopants. These findings are supported also by simulation results.

Opis:
The uniaxial anisotropy of magnetic properties of SrLa$\text{}_{1-x}$Nd$\text{}_{x}$AlO$\text{}_{4}$ single crystals (x = 0.01 and 0.05) was found from the measurements of temperature dependencies of magnetic susceptibility. Results of measurements, with magnetic field along a- and c-axis, are compared with the similar data obtained for CaNdAlO$\text{}_{4}$ crystal. The successful description of experimental data was done in frames of the crystal field approximation. The anisotropy of magnetic susceptibility appears due to crystal field acting on magnetic neodymium ions in a system without exchange interactions.

Superconductivity of indium diffused GaAs was investigated. The superconductivity in these samples was identified by the magnetic susceptibility and the characteristic field modulated microwave absorption. The static magnetic susceptibility was measured from 40 K down to 2.5 K. The result shows two distinctive diamagnetic contributions within 7 K-2.5 K range. These diamagnetic contributions were correlated with the excess of In and Ga metal in GaAs.

Intelligent transportation systems (ITS) are evolving in response to a range of factors, which are discussed in this paper in conjunction with major directions of future ITS development. The technology of cooperation between the various elements of infrastructure and vehicles will determine further evolution of telematic solutions, leading to synergies arising from both existing and new applications, as well as from the advent of the Internet of things in transportation. The next step in the development of such systems is Cooperative ITS. It already has a solid foundation in the European Union’s strategic documents on transportation, and the first implementations are under way.

Opis:
The implementation of ITS is carried out with the use of standard project management tools. Therefore, it includes certain phases. One of the most difficult and risky phase of ITS implementation is launching of such projects. An important factor causing this difficulty is the fact that launching is being done on „living organism”. Thus it has to be time-consuming mostly due to the necessity of a proper real-time city traffic data collection. Additional factors are occurring failures (eg. the tram network or traffic lights system) or accidents. Another problem are social expectations, which does not take into account the specifics of ITS implementation. The citizens expect immediate results. The aim of people responsible for the launching phase of such systems is to ensure smooth operation of all its components and to provide local community with information on a relatively long system activation to its full operation. This article presents the analysis of the launching phase of the biggest ITS in Poland.

Opis:
Haemophilus parasuis belongs to opportunistic microorganisms of undefined virulence. The purpose of the studies was to compare suitability of PCR/RFLP in our modification and ERIC PCR for epidemiological study of domestic strains of H. parasuis. The results were evaluated taking into account two different aspects: suitability of the tests for isolating the highest possible number of clone groups and subjective evaluation of the method judged with respect to the following criteria: difficulty, availability of equipment and reagents as well as time and cost of the study. The results obtained in the present study show that the two methods used for typing of H. parasuis had high discriminatory power. Taking into account this parameter it can be concluded that ERIC PCR is more suitable than PCR/RFLP. This justifies the use of ERIC PCR for routine epidemiological analyses of mentioned pathogen. Taking into account the complexity of method used, ERIC-PCR based on random amplification of DNA, proved to be comparable to PCR/RFLP. The last mentioned technique is relatively less expensive and labour-consuming, especially when diagnostic PCR method is used for the epidemiological studies.

Introduction and objectives. Surgical treatment due to brest cancer have an impact on women sexuality. There is a need for research about effective indications for sexology consultation in women after such treatment. The aim of this study is to determine the indications for sexology consultation in women after surgical treatment for breast cancer. Materials and method. We tested 42 women patients diagnosed with breast cancer who had undergone mastectomy 3 months before the study. 3 months after the surgery the women were surveyed using the Polish version of FSFI assessing sexual functioning in women. The result of PL-FSFI were compared with the control group. Results. It was found that the mean score of PL-FSFI in the study group 3 months after the surgery was 13.33 points (score range: 1.2–31.7; median 8.3 points) with a statistically significant difference in terms of areas: desire, arousal, lubrication and orgasm in favour of the control group. The total score of PL-FSFI was significantly lower in women after mastectomy than in women after breast-conserving surgery. It has been shown that sexually active women in whom the surgery concerned the right breast (on the side of the dominant hand) scored lower on the scale “sexual functioning” of QLQ-BR-23 than women with surgery of the left breast, with this difference being statistically significant. There was a statistically significant correlation between the baseline performance status on the Zubrod scale and the scales: desire, lubrication and satisfaction of PL-FSFI. Living in a small town proved to be statistically significant for predicting a lower risk of sexual dysfunction among the surveyed women. Conclusions. The women who underwent surgery due to breast cancer had a higher risk of sexual dysfunction compared to the general population. Higher risk of sexual dysfunction especially concerns women after mastectomy, those who underwent breast surgery on the side of the dominant hand, and those with a worse preoperative overall level of functioning of ≥ 1 point on the Zubrod scale. A lower risk of disorders was observed in women living in smaller towns. The above factors indicate the advisability for sexology consultation in women with breast cancer.
