Authors: Sialini P. , Sajdl P. , Havránek V. , Vrtílková V. 
Published: March 2016

Abstract
In the active zone of a nuclear reactor where zirconium alloys are used as a coating material, this material is subject to various harmful impacts. During water decomposition reactions, hydrogen and oxygen are evolved that may diffuse through the oxidic layer either through zirconium dioxide (ZrO2) crystals or along ZrO2 grains. The diffusion mechanism can be studied using the Ion Beam Analysis (IBA) method where nuclear reaction 18O(p,α)15N is used. A tube made of zirconium alloy E110 (with 1 wt. % of Nb) was used for making samples that were pre-exposed in UJP PRAHA a.s. and subsequently exposed to isotopically cleansed environment of H2
18O medium in an autoclave. The samples were analysed with gravimetric methods and IBA methods performed at the electrostatic particle accelerator Tandetron 4130 MC in the Nucler Physics Institute of the CAS, Řež. With IBA methods, the overall thicknesses of corrosion layers on the samples, element composition of the alloy and distribution of oxygen isotope 18O in the corrosion layer and its penetration in the alloy were identified. The retrieved data shows at the oxygen diffusion along ZrO2 grains because there are two peaks of 18O isotope concentrations in the corrosion layer. These peaks occur at the environment-oxide and oxide-metal interface. The element analysis identified the presence of undesirable hafnium.

Published: March 2016

Abstract
In recent years, there has been significant research focus that revolves around harvesting and minimising energy consumption by wireless sensor network nodes. When a sensor node is depleted of energy, it becomes unresponsive and disconnected from the network that can significantly influence the performance of the whole network. The purpose of the present research is to create a power supply management module in order to provide stable operating voltage for autonomous operations of radio signal repeaters, sensors or gateways of WSN. The developed management module is composed of a solar panel, lithium battery and power supply management module. The novelty of the research is the management module, which ensures stable and uninterrupted operations of electronic equipment in various power supply modes in different situations, simultaneously ensuring energy protection and sustainability of the module components. The management module is able to provide power supply of 5 V for electronics scheme independently, without power interruption switching between power sources and power flows in different directions.

Published: March 2016

Abstract
Research on the photovoltaic module efficiency in the south of Poland was conducted in 2009 in Stryszawa and afterwards in 2012 in Zabrze and Stryszawa. The research involved taking measurements of electric energy produced by systems of various power and technical solutions. The efficiency of PV modules was compared to the intensity of solar radiation in the locations under consideration and, thus, the efficiency of converting solar energy into electricity was determined. The research results facilitated designing and mounting of forty PV microsystems in Zabrze in 2014 (power from 2000 Wp to 3000 Wp). To the satisfaction of their users, they operate without failure.
The impact of brand image fit on attitude towards a brand alliance
Authors: Riley Debra , Charlton Nathalie , Wason Hillary 
Published: March 2016

Abstract
Co-branding has become an increasingly popular strategy over recent decades. Studies have found that the pre-existing attitudes to the parent brands, fit between their product categories and perceived fit in the brands themselves as important drivers of a co-brand success. Despite its importance, most studies have treated brand fit as a simple measure of complementarily and consistency. Recently, a few papers have challenged this view, suggesting that a broader range of brand attributes (such as personality, functional and hedonic characteristics, cultural meaning) should also be considered when investigating brand alliances. The current study draws on these findings, exploring the fit between partners’ brand images and how they influence perceptions of a brand alliance. We treat brand image as a multi-dimensional construct, consisting of economic, symbolic, sensory, futuristic and utilitarian elements. Using an experimental design with nine hypothetical brand pairings with 221 respondents, we find brand image fit provides greater explanatory power over a traditional unidimensional measure of brand fit, with economic, futuristic and utilitarian dimensions having a significant influence on co-brand perceptions.
Promises of silent salesman to the FMCG industry: an investigation using linear discriminant analysis approach
Authors: Shekhar Suraj Kushe , Raveendran P.T. 
Published: March 2016

Abstract
Packaging which is often called as the ‘silent salesman’ is an important component of marketing. Today the importance of packaging has risen to such an extent that product packaging is rightly called as the fifth ‘P’ of marketing mix. FMCG are products which are utilized by large number of people. The present study examined the discriminating power of five selected FMCG packaging variables namely ‘picture’, ‘colour’, ‘size’, ‘shape’ and ‘material’ amidst those who purchased FMCG based on these packaging variables and for those who purchased FMCG not based on these packaging variables. Descriptive research was carried out in the study. Respondents (students) were asked to rate four packaging variable on a five point Likert’s scale. Discriminant analysis showed that only two variables namely ‘Colour’ (.706) and ‘Shape’ (–.527) were good predictors. Variables ‘Picture’, ‘size’ and ‘material’ were considered as poor predictors as far as the student communities were considered. The cross validated classification showed that out of the 240 samples drawn, 91.8% of the cases were correctly classified.

The aim of this paper is to explore the impact of gender and country of origin in relation to entrepreneurial intentions and innovative cognitive style. Research was conducted using a sample of students majoring in information and communication technologies from Croatia and Slovenia. The results revealed the influence of gender, country, attitudes toward entrepreneurship, and innovative cognitive style on entrepreneurial intentions.
Understanding Management Concepts through Development of their Tool Box: The case of total quality management
Authors: Ćwiklicki Marek 
Published: March 2016

Abstract
This paper offers an alternative approach to defining the management concept. The proposed methodology relies on the identification of tools supporting the given concept. The author assumed that the identification of tools’ evolution gives clearer insights into circumstances of constant development of—by its nature—a more general concept. The tools’ classification resembles a phylogenic tree and is based on the idea of an affinity diagram. To provide the proof for such reasoning, the total quality management (TQM) concept was chosen. This proposition can be useful for better understanding origins and the development of management thought. It clarifies relationships among methods constituting frameworks of quality management.
Application of the Böhm chamber for reference beta dose measurements and the calibration of personal dosimeters
Authors: Skubacz Krystian 
Published: March 2016

Abstract
Thermoluminescent dosimeters (TLDs) currently used in personal and area dosimetry are often utilized to measure doses of ionizing radiation in fields with a more complex structure and therefore they should be calibrated in relation to different radiation types. The results of such calibration presented for UD-813 TLDs allowed for evaluation of their capability in relation to different radiation types like the beta and photon radiation of different energies and neutron radiation generated by the 241Am-Be source. The detector response for 60 keV photons was 10% higher than for the 662 keV gamma radiation of 137Cs. There were also response differences in relation to photon and beta radiation between detectors with an enhanced concentration of lithium 6Li and boron 10B and detectors containing a natural level of these isotopes. Measurements of the reference beta doses were performed with the help of the Böhm chamber. This method is relatively more complicated compared to determining the reference photon and neutron doses and is described thoroughly in this paper. The corrected current measured by the Böhm chamber for the chosen parameters was a linear function for an entire available range of the chamber depths. The percentage of errors related to the evaluated reference beta doses were below 2% despite a rather large number of corrections that should be taken into account. The calibration distances varied from 11 cm to 50 cm. For this range and beta particle energy, the absorption of radiation in the air was negligible and their attenuation had a predominantly geometric character.

Abstract
Intraoperative electron radiation therapy (IOERT) is a cancer treatment method that combines oncologic surgery with electron beam radiotherapy. This method can reduce the duration of entire tumor treatment and increase its effectiveness. Moreover, shortening the treatment time significantly reduces the cost and accessibility of the therapy. As a result of interdisciplinary research, an innovative accelerator for IOERT, the IntraLine, was developed. In the course of this work, four patent applications were filed. Today, the work is half way through. In the near future, the device will be optimized. New mechanical design solutions will be developed. Mechanical optimization will significantly reduce the weight of the device. Accelerators control system, which today is in the demo phase, will also be significantly upgraded. This paper describes the stages of the IntraLine accelerator development, its current state and plans for the future R&D work, within the scope of our new Intra-Dose project.

Authors: Giżyńska Marta , Blatkiewicz Dorota , Czyżew Beata , Gałecki Maciej , Gil-Ulkowska Małgorzata , Kukołowicz Paweł 
Published: March 2016

Abstract
Nowadays in radiotherapy, much effort is taken to minimize the irradiated volume and consequently minimize doses to healthy tissues. In our work, we tested the hypothesis that the mean dose distribution calculated from a few first fractions can serve as prediction of the cumulated dose distribution, representing the whole treatment. We made our tests for 25 prostate cancer patients treated with three orthogonal fields technique. We did a comparison of dose distribution calculated as a sum of dose distribution from each fraction with a dose distribution calculated with isocenter shifted for a mean setup error from a few first fractions. The cumulative dose distribution and predicted dose distributions are similar in terms of gamma (3 mm 3%) analysis, under condition that we know setup error from seven first fractions. We showed that the dose distribution calculated for the original plan with the isocenter shifted to the point, defined as the original isocenter corrected of the mean setup error estimated from the first seven fractions supports our hypothesis, i.e. can serve as a prediction for cumulative dose distribution.

Authors: Kilian Krzysztof , Pękal Anna , Juszczyk Julia 
Published: March 2016

Abstract
A method of 11C-methionine synthesis using ‘bubbling’ method is presented. 11C-methionine was synthesized via 11C methylation from L-cysteine thiolactone (2 mg) in a 300 μL solution of 2:1:1 (v/v) 1 M NaOH, ethanol, and water at ambient temperature (85°C, 5 min). The radiochemical purity of radiotracer was higher than 99% and enantiomeric purity (L-11C-methionine) was 91.6 ± 0.4%. The final product met the requirements of European Pharmacopoeia monograph. The proposed 11C-methionine synthesis is a reliable tool for routine manufacturing in clinical applications and animal studies.
Application of instruments of nuclear physics to the calculation of theoretical dose distributions in various organs of the human body for beams used in hadrontherapy
Authors: Maliszewska Weronika , Sękowski Przemysław , Skwira-Chalot Izabela 
Published: March 2016

Abstract
The area of interests of nuclear physics are studies of reactions, wherein atomic nuclei of projectile collide with target nuclei. An amount of energy lost by projectile nucleus during its passing through the target is a major issue – it is important to know how charged particles interact with matter. It is possible to afford this knowledge by using theoretical programs that calculate energy loss applying the Bethe-Bloch equation. Hadrontherapy, which is a field of still growing interest, is based on the interactions of charged particles with matter. Therefore, there exists a need of creating a simple model that could be used to the calculation of dose distributions in biological matter. Two programs (SRIM, Xeloss), used to the calculation of energy loss by nuclear physicist, have been adapted to determine the dose distributions in analogues of human tissues. Results of the calculations with those programs for beams used in hadrontherapy (e.g. 1H, 12C) will be compared with experimental data available in references.

Published: March 2016

Abstract
Magnesium tetraborate doped with dysprosium (MgB4O7:Dy) is known as a good thermoluminophor for personal dosimetry of gamma ray and X-ray radiation because of its high sensitivity and close tissue equivalence. This material can be produced by different routes. The sintered pastilles of magnesium tetraborate mixed with Teflon (40%) used in this work were manufactured at the Federal University of Sergipe, Department of Physics by the solid-state synthesis. Magnesium tetraborate was already used for high-dose dosimetry, exhibiting linearity for a wide range of doses. In this work, the authors examined its main characteristics prior to potential use of detectors in everyday dosimetry, comparing this material to a widely used LiF:Mg,Ti phosphor. The following tests influencing dosimetric peaks of MgB4O7:Dy were presented: (1) the shape of the glow curves, (2) annealing conditions and post-irradiation annealing and its influence for background of the detectors, (3) the choice of the heating rates at the read-out and (4) the threshold dose, that is, the lowest possible dose to be measured. Similar tests were performed with LiF:Mg,Ti detectors, produced and widely used in Poland. The results were compared and discussed.
New amino bisphosphonate compound for skeletal imaging: Comparison study with methylenediphosphonic acid (MDP) and (1-hydroxyethane-1,1-diyl) diphosphonic acid (HEDP)
Authors: Assaad Thaer 
Published: March 2016

Abstract
A novel bisphosphonate derivative (1-aminoethane-1,1-diyl)diphosphonic acid (AEDP) has been prepared and successfully labeled with 99mTc at high labeling yields. The in vivo biodistribution of 99mTc-AEDP has been investigated and compared with two reference compounds Tc-99m methylene diphosphonate (99mTc-MDP) and Tc-99m (1-hydroxyethylidene) diphosphonate (99mTc-HEDP). The biodistribution studies have demonstrated a high uptake of the radiotracer 99mTc-AEDP in the bone and a rapid clearance from the blood (such as the two technetium-labeled bone imaging agents in current use: 99mTc-MDP and 99mTc-HEDP). Additionally, the scintigraphic images of 99mTc-AEDP in normal rats have revealed high selective skeletal uptake.
Preliminary PM2.5 and PM10 fractions source apportionment complemented by statistical accuracy determination
Authors: Samek Lucyna , Stegowski Zdzislaw , Furman Leszek 
Published: March 2016

Abstract
Samples of PM10 and PM2.5 fractions were collected between the years 2010 and 2013 at the urban area of Krakow, Poland. Numerous types of air pollution sources are present at the site; these include steel and cement industries, traffic, municipal emission sources and biomass burning. Energy dispersive X-ray fluorescence was used to determine the concentrations of the following elements: Cl, K, Ca, Ti, Mn, Fe, Ni, Cu, Zn, Br, Rb, Sr, As and Pb within the collected samples. Defining the elements as indicators, airborne particulate matter (APM) source profiles were prepared by applying principal component analysis (PCA), factor analysis (FA) and multiple linear regression (MLR). Four different factors identifying possible air pollution sources for both PM10 and PM2.5 fractions were attributed to municipal emissions, biomass burning, steel industry, traffic, cement and metal industry, Zn and Pb industry and secondary aerosols. The uncertainty associated with each loading was determined by a statistical simulation method that took into account the individual elemental concentrations and their corresponding uncertainties. It will be possible to identify two or more sources of air particulate matter pollution for a single factor in case it is extremely difficult to separate the sources.
Evaluation of Scabiosa ochroleuca L. vitality after introduction on post-flotation wastes1
Authors: Muszyńska Ewa , Hanus-Fajerska Ewa 
Published: March 2016

Abstract
The aim of this study was to evaluate the Scabiosa ochroleuca suitability for growth on heavy metals contaminated substrate obtained as a result of Zn–Pb ores exploitation and their processing. Three variants of cultivation were tested in vegetative hall conditions: post-flotation wastes (control), wastes enriched with either mineral fertilisation or with sewage sludge. The possibility of future direct use of the studied species on post-flotation settling pond was determined on the basis of biometric measurements and analysis efficiency of photosynthetic apparatus, that is, pigments content and chlorophyll a fluorescence. The results showed that untreated wastes negatively influenced on plants morphological and physiological status. On the contrary, the application of sewage sludge improved growth and development of cream scabious. Thus, not only the selection of proper plant material, tolerant to toxic levels of heavy metals and other hostile conditions, but also the waste treatment are crucial when metalliferous areas are to be reclaimed.
