Opis:
The IgM paraprotein secretion is most frequently associated with Waldenström’s macroglobulinemia. In very rare cases it may also occur in multiple myeloma. The diagnostic and therapeutic process of a 84 year old male suffering from IgM multiple myeloma is described, including difficulties in establishing this diagnosis. Due to infectious complications, after the first cycle of melphalan– prednisone–bortezomib treatment, melphalan was stopped, subsequently, bortezomib and prednisone doses were also reduced. Two treatment interruptions have occurred. Despite reduced treatment intensity, the patient was in very good partial remission, while the toxicity profile was acceptable. IgM multiple myeloma should be included in the differential diagnosis of IgM paraproteinemia, also when osteolytic lesions and translocation 11:14 are not detected. Bortezomib-based therapy can be effective in elderly patients (also in those suffering from cardiac insufficiency), even when dose reduction is required.

Opis:
In this work, research on influence of multiwalled carbon nanotubes (MWCNTs), produced in Catalic Chemical Carbon Vapor Deposition, NANOCYLTM NC7000CNTs on a structure and properties of AISI 301 steel remelted by TIG arc. In the assessment of influence a type of carbon on properties and structure of austenitic steel, as a carbon filler was use also carburizer. In the specimens (AISI 301 plates) with dimensions 155×60×7 [mm] were drilled holes with 1.3 mm diameter and placed 0.5 mm under specimen surface. Next, to the drilled holes was implemented CNTs, carburizer and mixture of these both powders. Prepared specimens were remelted by TIG method on the CASTOTIG 2200 power source with 2.4 mm tungsten thoriated electrode with parameters sets for obtain 3.0 mm penetration depth. Remelted specimens were cut into the half of the welds distance and prepared for metallographic examinations. Cross sections of the specimens were tested on classical metallography microscopes, hardness tests, SEM analyses (on JEOL 5800 LV SEM EDX equipment) and phase identification by X-ray phase analysis on Philips APD X’Pert PW 3020 diffractometer. Hardness analysis indicates about 25% increase of hardness in the remelted area when the CTNs are used. In the specimens with carburizer there is no significant changes. SEM analyses of remelted areas on AISI 301 specimens modificated with CNTs, indicates that dark areas, initially interpret as one of the phase (based on optical microscope) is finally densely packed bladders with dimensions from 50 nm up to a few µm. These bladders are not present in the specimens with carburizer filler. High resolution scanning microscopy allow to observe in the this area protruding, longitudinal particles with 100-300 nm length. For identification of this phase, X-ray analysis was done. But very small dimensions of used CNTs (diameters about 9,5 nm), random orientation and small weight amount can make difficult or impossible to CNTs detection during XRD tests. It means that it is not possible to clearly determine nature of particles filling the cavities, it is only possible to suppose that they are CNTs beams with nanoparticles comes from their disintegration. Results of the researches indicates, that fill in the weld pool with different form of carbon (CNTs and carburizer) it is possible to achieve remelted beads with different structure and hardness distribution. It confirms validity of the research continuation with CNTs as a modifier of steels and also other metals and theirs alloys.

Opis:
The paper presents an original approach to device location detection in a building. The new method is based on a map of individual interiors, drawn up based on the measurements of the strength of wireless network signals for each building venue. The device is initially assigned to all venues whose descriptions sufficiently correspond with the current measurements taken by the device. A fuzzy assignment level for each of the potentially considered venues depends on the difference between the averaged network strengths for the venue and the signal strengths currently measured with the device for localization purposes. Ultimately, the device is assigned to the venue with the highest level of assignment.
W pracy przedstawiono oryginalną metodę lokalizowania urządzeń w budynku. Nowa metoda bazuje na mapie poszczególnych pomieszczeń, stworzonej w oparciu o pomiary sygnałów sieci bezprzewodowych zmierzonych w tych pomieszczeniach. Wstępnie urządzenie przypisywane jest do tych pomieszczeń, których opis w odpowiednim stopniu pokrywa się z pomiarami dokonanymi przez urządzenie. Stopień rozmytej przynależności do każdego z wstępnie wytypowanych pomieszczeń zależy z kolei od różnicy pomiędzy uśrednionymi wartościami sygnałów sieci bezprzewodowych i aktualnie zmierzonymi do celów lokalizacji. Ostatecznie urządzeniu przypisywane jest to pomieszczenie, dla którego stopień przynależności jest największy.

Opis:
Many museums in Poland and all over the world make use of mobile technologies. Unfortunately, neither Polish nor overseas applications offer universal solutions for users with different levels of knowledge and different disabilities. People with sight and hearing disabilities, as well as those physically handicapped, are very often culturally excluded, which means they are excluded from an important aspect of social life. As part of the project ‘OPENArt – Contemporary Art for All,’ a multimedia guide was developed in the form of an application for portable devices. It was designed in accordance with the participatory design methodology and principles of universal design. It facilitates access to works of art exposed to people with hearing and visual impairments. The application can be used to educate the blind, visually impaired, the deaf and hard of hearing, as well as people working with non-disabled children in arts and language classes. In the paper the innovative features of the guide were presented, and its educational values were characterized.

Opis:
This paper presents the results of the research on the physical activity of school youth in three European countries (Poland, Bulgaria, Kosovo) which are at different stages of socio-economic development and, therefore, of different possibilities and conditions in terms of leisure and mobility. The purpose of this cognitive study was to diagnose certain aspects of the lifestyle of young people aged 13-16 from Kosovo, Bulgaria and Poland, with a particular focus on physical activity. The practical aim, however, was an indication of such actions, arising from past experience that would aim at improving lifestyle, and could lead to the elimination or prevention of certain causes of physical inactivity by the youth of the countries surveyed. The research was conducted by the use of a diagnostic survey of a group of 524 people aged 13-16, among whom there were 88 people from Bulgaria, 136 people from Poland and 300 people from Kosovo. The research material was collected in 2012. The research that was carried out shows that the level of wealth (not so much of the family, but of the specific country) may have an impact on the choice of activities chosen by the youth. Undoubtedly socio-cultural factors and the tradition of social life, which impose certain ways of spending leisure time (as can be seen particularly in the case of the Bulgarian and Kosovar youth) are also of great importance. The above observations, taking into account local conditions, should be the starting point for all those who plan to introduce changes in the physical education systems in each of these countries in the future.

Opis:
A non-exclusive approach in conducting survey-based research which assumes the participation of people with disabilities is one of the important ethical aspects of the research process. The use of the tool, which has been designed in accordance with the universal user-oriented design, makes it possible for people with disabilities to take an active part in surveys. This means that they can present their attitudes and express opinions within the conducted surveys. The aim of the article is to present the issue of conducting surveys using an electronic questionnaire among deaf people, modelled on the Avatar PJM project. People with a hearing impairment, whose first or primary language used for communication is a sign language, should be given a questionnaire in an appropriate form enabling them to complete it easily. The discussed project presents a proposal to construct a questionnaire using the LimeSurvey software. The questionnaire has been adapted to the needs and expectations of the recipient group. The presented solution for designing a user-friendly research tool can be used in other types of research in this group of respondents (e.g. industrial or educational research) or can become an inspiration for further research in this field.

Opis:
In fungi transfer of the first mannosyl residue to proteins during their O-glycosylation is catalyzed by protein O-mannosyltransferases encoded by pmt genes. Disruption of the pmt1 gene in Trichoderma caused a significant decrease in the total activity of protein O-mannosyltransferases. Moreover, disruption of the pmt1 gene also led to osmotic sensitivity of the strain, indicating an essential role of the PMTI protein activity for cell wall synthesis. At the same time, the strain was defective in septa formation, producing only half the number of septa per unit length of hypha compared with the wild type. Disruption of the pmt1 gene decreased protein secretion but had no effect on glycosylation of secreted proteins, which suggests that PMTI protein O-mannosyltranferase does not take part in glycosylation of these proteins.
