Opis:
Differential scanning calorimetry is discussed as a tool for characterization of shape memory alloy materials with the example of $Ni_{51at.%}-Ti$ polycrystalline material. Some inconsistencies connected with the differential scanning calorimetry analysis results present in the contemporary literature are indicated, for example large discrepancies in the registered heats of phase transition or differences in registered heats of forward and reverse phase transition, especially in the case of multi-stage phase transition sequences. An attempt is undertaken to explain some of the discrepancies. The overall conclusion from the present work is that forward and reverse sensible heats of phase transition are equal, and discrepancies reported in the literature are artefacts. It is recommended that as a standard practice of differential scanning calorimetry analysis of shape memory alloy materials not only characteristic temperatures but also sensible heat of phase transition should be reported, which can be done at practically no additional cost.

Opis:
The aim of this article is to indicate the need for a deepening, systematizing and codifying of the theoretical and practical knowledge on IT project management, in the area of management decision-making processes. The scope of decisions made by managers is constantly on the increase. Project managers make decisions not only within the classic triangle of constraints, which consists of a schedule, a budget and the project scope, but also in reference to a number of other problems which occur during project execution. The observed need to identify and define all the factors which are present in projects results in the identification of a finite set of variables for decision-making and for the decisions themselves and, finally, in determining their mutual correlation.

Opis:
The aim of this paper is to present the quantitative perspective of the agile transformation processes in IT organisations. The phenomenon of agile transformation becomes a complex challenge for an IT organisation since it has not been analysed in detail so far. There is no research on the readiness of IT organisations to realise agile transformation processes. Such processes also prove to have uncontrolled character. Therefore, to minimise the risk of failure referring to the realisation of transformation processes, it is necessary to monitor them. It is also necessary to identify and analyse such processes to ensure their continuous character.

Opis:
Objective: To evaluate the health-related quality of life (HRQOL) in patients aroused from prolonged coma after a severe traumatic brain injury (TBI) treated by physiotherapists trained in the ‘Academy of Life’ programme. It was assumed that physiotherapists who acquired this knowledge and experience would create a better therapeutic milieu, and would be more effective than physiotherapists who had not received this training. Material and methods: 40 patients who had suffered a severe TBI in a motor vehicle accident and had been aroused from prolonged coma were examined. All the patients underwent long-term rehabilitation according to a standard, phased programme. They were divided into two numerically even groups: an experimental group, treated by therapists trained in the ‘Academy of Life’ programme, and a control group, treated by physiotherapists who were not trained in this programme. The research instruments included an analysis of documentation, a structured clinical interview, and the Quality of Life Scale. Results: As hypothesized, the experimental group showed significant improvement in HRQOL, whereas in the control group improvement was statistically non-significant. Conclusions: The patients from the experimental group, treated by physiotherapists trained in the ‘Academy of Life’, obtained a significantly greater improvement in physical and social functioning, and thus in HRQOL, than patients from the control group.

Opis:
The paper presents a comparative analysis of the emission of CO, NOx, CO2 and gas mileage for two heavy-duty long haulage vehicles. The tests were performed on the same test road. The test route reflected typical daily operation of heavy-duty vehicles – a drive to the loading/unloading zone and cruise on national roads. In the investigations, the authors used a portable exhaust emissions analyzer (SEMTECH DS, PEMS – Portable Emissions Measurement System). Based on the performed analysis, optimum engine was selected for long haulage vehicles under conditions of Polish transport and logistic infrastructure in terms of fuel consumption.

Opis:
The neutron emission rate is a crucial parameter for most of the radiation sources that emit neutrons. In the case of large fusion devices the determination of this parameter is necessary for a proper assessment of the power release and the prediction for the neutron budget. The 14 MeV neutron generator will be used for calibration of neutron diagnostics at JET and ITER facilities. The stability of the neutron generator working parameters like emission and angular homogeneity affects the accuracy of calibration other neutron diagnostics. The aim of our experiment was to confi rm the usefulness of yttrium activation method for monitoring of the neutron generator SODERN Model: GENIE 16. The reaction rate induced by neutrons inside the yttrium sample was indirectly measured by activation of the yttrium sample, and then by means of the γ-spectrometry method. The pre-calibrated HPGe detector was used to determine the yttrium radioactivity. The emissivity of neutron generator calculated on the basis of the measured radioactivity was compared with the value resulting from its electrical settings, and both of these values were found to be consistent. This allowed for a positive verifi cation of the reaction cross section that was used to determine the reaction rate (6.45 × 10–21 reactions per second) and the neutron emission rate (1.04 × 108 n·s–1). Our study confi rms usefulness of the yttrium activation method for monitoring of the neutron generator.

Opis:
Air pollution has become an important worldwide problem. The European Commission credits road and water transport as the major source of NOx pollution, and of being responsible for around 50% of the total air pollution in urban areas. In Poland, around 45% of the country NOx emissions are attributed to transportation. During the last decade, the use of SCR technologies have gained popularity as a method for NOx reduction, the technology is widely considered as one of the solutions for road transport emissions. SCR technology had previously been employed in stationary plants, maritime transportation and other installations using combustion processes in which exhaust conditions are easier to control. The advance on the technology led to the introduction of the first heavy-duty vehicle with an SCR system into the market in 2004. New technologies and applications are constantly appearing, for example, SCR exhaust gas cleaning systems for reciprocating engines are still under development and compression ignition engines can be found in a number of different applications. The technology still needs to be studied and improved as constant problems and knowledge is required in issues such as urea injection, crystallization and NOx reduction efficiency. Moreover, the designs intended for heavy duty vehicles need to meet vehicle limitations and EURO emissions restrictions. This paper presents a review of the different SCR system designs derived from the various factors and regulations in the automotive industry, which have influenced the technology, along with a parametric study of a proprietary SCR system for heavy-duty application.

Opis:
The power output of plasma experiments and fusion reactors is a crucial parameter. It is determined by neutron yields that are proportional and directly related to the fusion yield. The number of emitted neutrons should be known for safety reasons and for neutron budget management. The PF-1000 is the large plasma facility based on the plasma focus phenomenon. PF-1000 is operating in the Institute of Plasma Physics and Laser Microfusion in Warsaw. Neutron yield changes during subsequent pulses, which is immanent part of this type device and so it must be monitored in terms of neutron emission. The reference diagnostic intended for this purpose is the silver activation counter (SAC) used for many years. Our previous studies demonstrated the applicability of radio-yttrium for neutron yield measurements during the deuterium campaign on the PF-1000 facility. The obtained results were compared with data from silver activation counter and shown linear dependence but with some protuberances in local scale. Correlation between results for both neutron monitors was maintained. But the yttrium monitor registered the fast energy neutron that reached measurement apparatus directly from the plasma pinch. Based on the preliminary experiences, the yttrium monitor was designed to automatically register neutron-induced yttrium activity. The MCNP geometrical model of PF-1000 and yttrium monitor were both used for calculation of the activation coefficient for yttrium. The yttrium monitor has been established as the permanent diagnostic for monitoring fusion reactions in the PF-1000 device.

Opis:
The paper refers to a kind of nanoscale characterization of superparamagnetic materials above and below the so-called blocking temperature. It is propose to apply the Stoner-Wohlfarth model of nanoparticles magnetization supplemented by the two-level kinetic model, determining behavior in T>0. This approach allows determination of distribution of magnetic moments and energetic barriers of magnetic objects based on magnetization curves. In many cases, the determined distribution of magnetic moments can be recalculated into average size of the magnetic objects giving finally a nano/microscaled picture of the material. The proposed method was successfully used in characterization of diluted magnetics, nanocomposites, powders and even for human hemoglobin. In the paper the basic theory and its application to the nanoscale characterization is discussed in detail.
