    Opis:
    The indoor environment of buildings significantly affects the well-being and health of room users. Experiencing thermal discomfort reduces concentration and productivity during study or work, causing drowsiness, fatigue or deterioration in general well-being. The study focuses on presenting the results of the questionnaire study on the symptoms of sick building syndromes (SBS), namely: dizziness, nausea, eye pain and nasal mucosa, experienced by 69 students during a lecture in a large and modern auditorium of Kielce University of Technology. The results show that many students experienced SBS symptoms, which seem to have affected their concentration during the class. The article also discusses the thermal sensations of the students with a focus on comparing the obtained results with the Fanger model of thermal comfort. The discrepancy between the model calculation results and the experimental data has been observed and discussed.

    Opis:
    A novel approach to a trigger mode in the Gas Electron Multiplier (GEM) detector readout system is presented. The system is already installed at WEST tokamak. The article briefly describes the architecture of the GEM detector and the measurement system. Currently the system can work in two trigger modes: Global Trigger and Local Trigger. All trigger processing blocks are parts of the Charge Signal Sequencer module which is responsible for transferring data to the PC. Therefore, the article presents structure of the Sequencer with details about basic blocks, theirs functionality and output data configuration. The Sequencer with the trigger algorithms is implemented in an FPGA chip from Xilinx. Global Trigger, which is a default mode for the system, is not efficient and has limitations due to storing much data without any information. Local trigger which is under tests, removes data redundancy and is constructed to send only valid data, but the rest of the software, especially on the PC side, is still under development. Therefore authors propose the trigger mode which combines functionality of two existing modes. The proposed trigger, called Zero Suppression Trigger, is compatible with the existing interfaces of the PC software, but is also capable to verify and filter incoming signals and transfer only recognized events. The results of the implementation and simulation are presented.

    Opis:
    Genistein, the principal isoflavone constituent of soybean, attracts much attention as a natural molecule with significant affinity towards targets of potential medicinal interest, but also as a food supplement or prospective chemopreventive agent. Since its physicochemical properties are considered suboptimal for drug development, much effort has been invested in designing its analogs and conjugates in hope to obtain compounds with improved efficacy and selectivity. The aim of this article is to summarize current knowledge about the properties of synthetic genistein derivatives and to discuss possible clinical application of selected novel compounds. Some basic information concerning chemical reactivity of genistein, relevant to the synthesis of its derivatives, is also presented.

    Opis:
    The validation of the measurements quality after on-site diagnostic system installation is necessary in order to provide reliable data and output results. This topic is often neglected or not discussed in detail regarding measurement systems. In the paper recently installed system for soft X-ray measurements is described in introduction. The system is based on multichannel GEM detector and the data is collected and sent in special format to PC unit for further postprocessing. The unique feature of the system is the ability to compute final data based on raw data only. The raw data is selected upon algorithms by FPGA units. The FPGAs are connected to the analog frontend of the system and able to register all of the signals and collect the useful data. The interface used for data streaming is PCIe Gen2 x4 for each FPGA, therefore high throughput of the system is ensured. The paper then discusses the properties of the installation environment of the system and basic functionality mode. New features are described, both in theoretical and practical approach. New modes correspond to the data quality monitoring features implemented for the system, that provide extra information to the postprocessing stage and final algorithms. In the article is described also additional mode to perform hardware simulation of signals in a tokamak-like environment using FPGAs. The summary describes the implemented features of the data quality monitoring features and additional modes of the system.

    Opis:
    The “Polish Research on Gastric Cancer” project has been continued since 1986. The main aim of this project, which is a multicenter and interdisciplinary research, is enhancing the treatment results of gastric cancer patients by developing and promoting the use of optimal methods for diagnosis and treatment, both surgical as well as combined. One of the more important achievements of the project is the development and publication of a document named “Polish Consensus on Treatment of Patients with Gastric Cancer”, whose first version was published in 1998. Following versions were updated adequately to changing trends in the proceedings in patients with gastric cancer. A scientific symposium on “Polish Consensus on Treatment of Gastric Cancer – update 2016” was held in 3-4 June 2016 in Cracow. During the symposium a panel session was held during which all authors publicly presented the Consensus assumptions to be discussed further. Moreover, the already mentioned session was preceded by a correspondence as well as a working meeting in order to consolidate the position. It has to be underlined that the directions and guidelines included in the Consensus are not the arbitrarily assumed rules of conduct in a legal aspect and as such every doctor/team of doctors is entitled to make different decisions as long as they are beneficial to a patient with gastric cancer. The Consensus discusses as follows: a) recommended qualifications (stage of advancement, pathological, lymph node topography and the extent of lymphadenectomy, division of cancer of the gastroesophageal junction), b) rules for diagnostics including recommendations regarding endoscopic examination and clinical evaluation of the advancement stage, c) recommendations regarding surgical treatment (extent of resection, extent of lymphadenectomy, tactics of proceedings in cancer of the gastroesophageal junction), d) recommendations regarding combined treatment with chemotherapy or radiotherapy, e) place of endoscopic and less invasive surgery in the treatment of gastric cancer. This publication is a summary of the arrangements made in the panel session during the abovementioned scientific symposium in Cracow in 2016.

    Opis:
    Traces of mechanical wear appear on co-working surfaces in the operation of precision fluid bearings. This should not be the case, since fluid friction and uninterrupted oil film should be present in a friction pair, which is a concept that this paper attempts to outline. The way friction forces, resistance, and oil film vary as unit pressure rises linearly is discussed. Three stages of the variations are distinguished. At the first stage, the oil film thickness and force of friction remain steady while the resistance declines. Stage two is temporary: Triboelectrical phenomena already escalate considerably and begin to decide effects of the friction process while a lubricant loses rheological properties of the Newtonian fluid. Hydrodynamic friction continues at the third stage, yet the triboelectrical effects are decided by stabilised triboelectrical phenomena. The third range can be identified as boundary friction where the layer separating surfaces is thicker than in the area of Newtonian rheology. This is very good in respect to wear, but higher-energy (not electrically neutral) particles cause increases in friction resistances. This range seems to exhibit a very high potential for being controlled with an adequate selection of oil based additions.
    W trakcie eksploatacji precyzyjnych łożysk ślizgowych na współpracujących powierzchniach pojawiają się ślady zużycia mechanicznego. Zjawisko takie nie powinno mieć miejsca, gdyż w węźle ciernym powinno występować tarcie płynne z nieprzerwanym filmem olejowym. W publikacji przedstawiono, w jaki sposób zmieniają się wartości siły tarcia, rezystancji oraz filmu olejowego wraz z liniowym wzrostem nacisku jednostkowego. Wyodrębniono trzy etapy zachodzących zmian. W pierwszym etapie zaobserwowano utrzymywanie się na zbliżonym poziomie grubości filmu olejowego i siły tarcia, przy jednoczesnym zmniejszaniu się wartości rezystancji. Etap II jest etapem przejściowym, w którym znacząco narastają już zjawiska triboelektryczne i one zaczynają decydować o efektach procesu tarcia, a środek smarowy traci właściwości reologiczne cieczy newtonowskiej. W etapie III nadal występuje tarcie hydrodynamiczne, ale o efektach tarcia decydują ustabilizowane zjawiska triboelektryczne. Wobec powyższego zakres trzeci możemy identyfikować jako tarcie graniczne, w którym warstewka rozdzielająca powierzchnie jest grubsza niż w obszarze reologii newtonowskiej. Jest to bardzo korzystne z punktu widzenia zużycia, ale cząsteczki o wyższej energii (nieobojętne elektrycznie) powodują zwiększenie oporów tarcia. Wydaje się, że ten zakres posiada bardzo duże potencjalne możliwości sterowania nim poprzez odpowiedni dobór dodatków do bazy olejowej.

    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.

    Opis:
    Liver transplantation is a well-established treatment of patients with end-stage liver disease and selected liver tumors. Remarkable progress has been made over the last years concerning nearly all of its aspects. The aim of this study was to evaluate the evolution of long-term outcomes after liver transplantations performed in the Department of General, Transplant and Liver Surgery (Medical University of Warsaw). Material and methods. Data of 1500 liver transplantations performed between 1989 and 2014 were retrospectively analyzed. Transplantations were divided into 3 groups: group 1 including first 500 operations, group 2 including subsequent 500, and group 3 comprising the most recent 500. Five year overall and graft survival were set as outcome measures. Results. Increased number of transplantations performed at the site was associated with increased age of the recipients (p<0.001) and donors (p<0.001), increased rate of male recipients (p<0.001), and increased rate of piggyback operations (p<0.001), and decreased MELD (p<0.001), as well as decreased blood (p=0.006) and plasma (p<0.001) transfusions. Overall survival was 71.6% at 5 years in group 1, 74.5% at 5 years in group 2, and 85% at 2.9 years in group 3 (p=0.008). Improvement of overall survival was particularly observed for primary transplantations (p=0.004). Increased graft survival rates did not reach the level of significance (p=0.136). Conclusions. Long-term outcomes after liver transplantations performed in the Department of General, Transplant and Liver Surgery are comparable to those achieved in the largest transplant centers worldwide and are continuously improving despite increasing recipient age and wider utilization of organs procured from older donors.
