Opis:
The aim of the study was to analyze indications and results of the first one thousand liver transplantations at Chair and Clinic of General, Transplantation and Liver Surgery, Medical University of Warsaw.Material and methods. Data from 1000 transplantations (944 patients) performed at Chair and Clinic of General, Transplantation and Liver Surgery between 1994 and 2011 were analyzed retrospectively. These included 943 first transplantations and 55 retransplantations and 2 re-retransplantations. Frequency of particular indications for first transplantation and retransplantations was established. Perioperative mortality was defined as death within 30 days after the transplantation. Kaplan-Meier survival analysis was used to estimate 5-year patient and graft survival.Results. The most common indications for first transplantation included: liver failure caused by hepatitis C infection (27.8%) and hepatitis B infection (18%) and alcoholic liver disease (17.7%). Early (< 6 months) and late (> 6 months) retransplantations were dominated by hepatic artery thrombosis (54.3%) and recurrence of the underlying disease (45%). Perioperative mortality rate was 8.9% for first transplantations and 34.5% for retransplantations. Five-year patient and graft survival rate was 74.3% and 71%, respectively, after first transplantations and 54.7% and 52.9%, respectively, after retransplantations.Conclusions. Development of liver transplantation program provided more than 1000 transplantations and excellent long-term results. Liver failure caused by hepatitis C and B infections remains the most common cause of liver transplantation and structure of other indications is consistent with European data.

On 21 of July 2001, small fragment of metal has been found on side walk, near branch of Silesian University in Cieszyn, by Ms. Małgorzata Kotowiecki. After a few years, the metallic fragment was carefully study. The investigation show that the metallic element has meteoritic origin. The mineral composition of the meteorite (kamacite, taenite, tetraenite, troilite, daubreelite) classify it as an iron meteorite and the most probably is representative of octahedrite. The meteorite has features of shock metamorphism and represent very old fall. It could be supposed that the meteorite has been transported to the destination place, together with gravel.

Opis:
Morasko meteorite (IAB octahedrite) contains numerous graphite-troilite inclusions. Within these inclusions, many mineral phases have been found, including native elements, sulphides, tellurides, oxides, phosphates and silicates. Apart from dominant graphite and troilite, the following minerals occur: copper, sphalerite, daubreelite, chromite, cosmochlor, enstatite, albite and orthoclase; phosphates (buchwaldite and brianite) are found occasionally, whereas djerfischerite, altaite, olivine and silica are rare. The mineral composition of the nodules suggests a more complex origin of the Morasko-type meteorites than currently assumed.

Opis:
Sixteen specimens of the Morasko, one specimen of Seeläsgen and one specimen of Jankowo Dolne irons were analyzed with INAA to determine contents of 14 siderophile elements. The samples selected for analyses have their structures described and the presence or absence of cohenite checked. For preliminary interpretation, we have chosen elements determined with highest accuracy: Co, Ni, Ga, As, Ir and Au. The results are shown in tables and diagrams. It has been found that there are no significant differences in composition between fragments with and without cohenite. The observed low contents if iridium are not accompanied by lower contents of elements showing similar behavior during crystallization: platinum and tungsten, which suggests that fractional crystallization was not the reason of lower iridium content. Similar concentrations of elements have been found in all the Morasko specimens, and in the Seeläsgen and Jankowo Dolne irons, which suggests that all these meteorites come from one iron shower.

Opis:
Since its discovery, the Morasko meteorite has been the subject of many studies. Among the publications summarising the mineralogical and geochemical characteristics of the Morasko meteorite, two monographs are worth mentioning by: Dominik (1976) and Muszyński et al. (2012), in which the essentialfeatures of the Morasko meteorite were presented. Since the first piece of the Morasko meteorite was to be explored, the analysis of mineral composition has been conducted with more and more specialised and sophisticated instrumental methods. As it is well known, the Morasko meteorite is classified into the group of iron meteorites IAB MG, and consists mainly of the crystalline Fe-Ni alloy in the form of two minerals: kamacite and taenite, accompanied by tetrataenite. A commonly found structure of the mineral composition of the Morasko meteorite, as regards other iron meteorites, are graphite-troilite nodules, which contain silicate and phosphate minerals. This paper presents a review ofresearch on the mineralogy and geochemistry of the Morasko meteorite, where a number of instrumental tests have been used, from microscopic observations to microchemical semiquantitative analyses using scanning electron microscopy (SEM-EDS), microchemical quantitative analyses using an electron microprobe (WDS), to the structural methods applying Raman spectroscopy. The results of microscopic, microchemical and microstructural investigations, which have included the outer layer of the meteorite known as a fusion crust, have been presented against the petrographic composition of the meteorite. Besides, the type of sediment attached to the outer meteorite layer was examined. The research, conducted on two dozen meteorite fragments, allowed distinguishing two different zones concerning mineralogy and geochemistry, and to determine microstructural changes within them, most probably created in the processes related to the moment of the meteorite impact.

Opis:
For many years, satellite systems have seen widespread use in a variety of technical applications, as well as in operations related to setting-out and the exploitation of track infrastructure. Their main applications include an inventory of the trackage course and detecting changes in its position. In both of these tasks, the most important element that determines the quality of an analyses is the high accuracy of the determinations being carried out. Satellite surveying techniques are not always sufficiently accurate, and in such cases, it is necessary to employ other land surveying methods to process surveying data. This article presents the authors’ considerations with regards to the possibility of applying one of the most common land surveying adjustment methods, the parametric method, to operations related to an inventory of tram infrastructure in Gdańsk. The results are based on surveys carried out during a surveying campaign in the autumn of 2018. The considerations presented in the article concern a small part of the research conducted under project No. POIR.04.01.01-00-0017/17 entitled “Development of an innovative method for determining the precise trajectory of a railborne vehicle” which is being implemented by a consortium of Gdansk University of Technology and Gdynia Maritime University

Opis:
Determining the course of a railway track axis using satellite methods relies on ensuring the precise assembly of GNSS receivers in dedicated measuring devices. Depending on the number of receivers, solutions that are based on placing the apparatus directly above the railway track axis (as well as in eccentric positions) are used to indirectly obtain data to form the basis of the desired results. This publication describes the installation of five GNSS receivers on a mobile measuring platform as part of the InnoSatTrack project. The methodology and the procedure of the geodetic measurements required to obtain the geometrical configuration of the measuring apparatus, specified in the technical project, are presented. The publication presents the principles of total station measurement methods as well as the steps taken to achieve precise results from staking out. The process of acquiring the same configuration of the GNSS receivers, based on the geometry of the squares on the two measuring platforms that were used in the research, has been shown. The final determination of the position of the receivers did not exceed an error of 0.010 m with an average error of 0.003 m, despite the occurrence of mounting difficulties. The results have demonstrated the high credibility and effectiveness of the presented solution.

Opis:
Each year, global navigation satellite systems (GNSS) improve their accuracy, availability, continuity, integrity, and reliability. Due to these continual improvements, the systems are increasingly used in various modes of transport, including rail transport, the subject of this publication. GNSS are used for rail passenger information, rail traffic management, and rail traffic control. These applications differ in the positioning requirements that satellite navigation systems must meet. This article presents the methods and systems of rolling stock location and tracking using the Polish State Railways (PKP) as an example. The information on the equipment used for train positioning is not specified anywhere, hence they may differ, even for the same multiple units travelling in different parts of the country. In addition, the publication presents the progress of the European Train Control System (ETCS) implementation by the PKP.

Opis:
This article examines one of the basic issues related to the technique of mobile satellite measurements in railway tracks. This problem concerns the correction of the determined coordinates of the track centerline. The need to perform this operation results from the GNSS receivers positioning at a certain height above the level of the existing track axis, leading to longitudinal and lateral shifts of antennas. The key problem here is the determination of the local horizontal coordinate system in each measured position. For the analysis, the authors defined the directional baseline vector of the measuring platform on the basis of positions given by two satellite antennas, positioned over the pivots of its bogies. This work presents the procedure for determining the corrections values.
W pracy poruszono jedną z podstawowych kwestii związanych z techniką mobilnych pomiarów satelitarnych w torze kolejowym – korygowanie wyznaczonych współrzędnych osi toru. Konieczność przeprowadzenia tej operacji wynika z ustawienia anten GNSS na pewnej wysokości nad poziomem istniejącej osi toru, przy występowaniu jego pochylenia w kierunku podłużnym i poprzecznym. Kluczowym problemem staje się przy tym konieczność określania w każdym punkcie pomiarowym kierunków osi układu współrzędnych w płaszczyźnie poziomej. W omawianej metodzie posłużono się kierunkowym wektorem bazowym, wyznaczonym na podstawie współrzędnych anten usytuowanych nad czopami skrętów obydwu wózków platformy. W pracy przedstawiono procedurę określania wartości korekt.

Opis:
The article discusses the applicability of a novel method to determine horizontal curvature of the railway track axis based on results of mobile satellite measurements. The method is based on inclination angle changes of a moving chord in the Cartesian coordinate system. In the presented case, the variant referred to as the method of two virtual chords is applied. It consists in maneuvering with only one GNSS (Global Navigation Satellite System) receiver. The assumptions of the novel method are formulated, and an assessment of its application in the performed campaign of mobile satellite measurements is presented. The shape of the measured railway axis is shown in the national spatial reference system PL-2000, and the speed of the measuring trolley during measurement is calculated based on the recorded coordinates. It has been observed that over the test section, the curvature ordinates differ from the expected waveform, which can be caused by disturbances of the measuring trolley trajectory. However, this problem can easily be overcome by filtering the measured track axis ordinates to obtain the correct shape – this refers to all track segments: straight sections, circular arcs and transition curves. The virtual chord method can also constitute the basis for assessing the quality of the recorded satellite signal. The performed analysis has shown high accuracy of the measuring process.
