Opis:
Ochrona klimatu wymaga wdrożenia bezemisyjnych źródeł energii, takich jak reaktory jądrowe. Reaktory wysokotemperaturowe mogą stanowić doskonałe uzupełnienie wielkoskalowej energetyki jądrowej, poprzez zaopatrzenie rynku energetycznego w wysokotemperaturowe ciepło, do różnych procesów technologicznych. Pierwszym krokiem na drodze do wdrożenia technologii reaktorów wysokotemperaturowych w Polsce była realizacja projektu GOSPOSTRATEG-HTR. Niniejszy artykuł stanowi podsumowanie najważniejszych celów i osiągnięć projektu.
Climate protection requires the deployment of zero-emission energy sources, such as nuclear reactors. Hightemperature reactors can be a perfect complement to large-scale nuclear energy by supplying the energy market with hightemperature heat for various technological processes. The first step towards the implementation of high-temperature reactor technology in Poland was the implementation of the GOSPOSTRATEG-HTR project. This article is a summary of the most important goals and achievements of the project.

Opis:
Proteins with a non-trivial topological structure are currently well recognized, while a knotted protein chain represents a new motif in protein three dimensional folds. Recent comprehensive analysis of the Protein Data Base shows that knotted proteins represent 1.5% of known protein structures. Determination of a free energy landscape of knotted proteins, and its understanding provides a serious challenge for both experimentalists and theoreticians. Moreover the role of a knot for biological activity of protein still remains elusive. In this work we study the smallest knotted proteins ( PDB code 2efv) to understand/investigate their free energy landscape, by means of extensive molecular dynamics simulations. We explore the dependence of the thermodynamics, kinetics and protein folding pathways on the native-likes contact maps and on the length of the chain. We analyze two sets of native-like contacts , which differ by a number of long range interactions, and we consider the 2efv protein with two different lengths of its C-terminus end. We identify the subset of native contacts sufficient to explore the entire free energy landscape. Then, we analyze the influence of the remaining set of native contacts – we show that the set of additional contacts may enhance folding kinetics, and that it has an influence on folding pathways.

Opis:
In this study plasma concentrations of IL-1α and IL-8 in 29 female dogs with malignant mammary gland tumours (19 without metastasis and 10 with metastasis) and in 10 healthy control animals were determined. Concentrations of IL-1α and IL-8 were analysed using a specific canine ELISA assay. Mean plasma concentrations of IL-1α and IL-8 were significantly higher (p<0.05) in female dogs with both non-metastatic and metastatic malignant tumours compared to the healthy animals. The concentrations of both tested cytokines were significantly increased (p<0.05) in the dogs with metastasis. In female dogs with mammary carcinomas, the plasma concentration of IL-1α was significantly higher (p<0.05) in the animals with grade 3 tumours compared to the dogs with grade 1 tumours. The concentration of IL-8 was significantly higher (p<0.05) in the dogs with grade 3 tumours compared to that found in the animals with grade 1 and grade 2 tumours. A moderate correlation (r=0.433) was found between IL-1α and IL-8 concentrations in the female dogs. These findings suggest that increased malignancy and invasiveness of canine mammary tumours is associated with an increased production of IL-1α and IL-8 in the tumour microenvironment, which, in turn, leads to an increase in their circulating levels. This may indicate that circulating levels of the cytokines investigated could be considered as diagnostic and prognostic markers in canine malignant mammary tumours. However, further studies in this fields are needed.

Opis:
The natural range of the dwarf birch (Betula nana L.) includes the boreal, subarctic and arctic regions of Europe, Asia and North America, where it is relatively common. In Poland, it is a relict species occurring in fragmented populations. Using the random amplification of polymorphic DNA (RAPD) technique, we investigated the genetic diversity of the four Swedish populations representing a part of the continuous range of dwarf birch. With the knowledge of the level of genetic diversity of a population from a continuous distribution, we can assess the genetic status of polish populations and answer the question if habitat fragmentation and a decrease in population size lead to a loss in genetic diversity. Knowledge of genetic diversity is important for species conservation, especially to predict their ability to respond to environmental pressures. We found that the populations Abisko, Malbo, Gällivare and Storlien, which are located at the edge of the natural range of B. nana and occupy different habitats, are genetically diverse to varying degrees. The northern populations from Abisko and Gällivare showed a lower level of genetic polymorphism than the population from Malbo, the southernmost site of dwarf birch in Sweden. The data presented indicate higher genetic diversity existed within populations, whereas genetic differentiation between populations was lower. The high level of genetic differentiation within B. nana populations that were analysed in the present study may be explained by a limited capacity for dispersal among populations via both pollen and seeds. We found that the level of genetic diversity in one of the Polish populations of B. nana is comparable to that in areas in Scandinavia where populations are large and continuous. Based on these studies, we conclude that the “Linje” population has sufficient genetic resources.

Opis:
Silicon is the second most prevalent element in the Earth’s crust and the third most abundant trace element in the human body. Silicon compounds counteract the crystallization of minerals in the urinary tract, impede the deposition of lipid plaques in the walls of blood vessels and through their presence prevent the absorption of calcium compounds, which reduce the elasticity of blood vessels and may cause diseases of the circulatory system. The article presents the results of studies on the level of silicon and magnesium in the hair of patients with atherosclerosis (N=137, age 60-94) and the control group of healthy people (N=242, age 20-80). The measured silicon content by ICP-OES in healthy people decreases with age, especially after 40 years of age, and ranges from 43.3±7.8 to 22.4±8.4 µg g-1. The average level of silicon in patients with atherosclerosis is much lower and ranges from 14.0±6.7 to 7.9±4.9 µg g-1, depending on the age range. However, a wide spread of Si values is observed in every age group, even in the group of healthy military students living for several years in the same conditions and using the same diet. Among the patients, there is a group with Si levels below 10 µg g-1, a value that does not appear in healthy people, even those aged 70-80. Due to the presence of a concentration range of 10-20 µg g-1 among all tested samples, the Si content in the hair cannot be unequivocally considered a certain atherosclerosis marker, although particularly low Si content below 10 µg g-1 should be a clear signal heralding a disease. In such patients, there is also a significantly reduced level of magnesium (5-15 µg g-1) compared with the norms adopted in Poland (25-35 µg g-1).

Opis:
The operating zone of a radio navigation system is one of its main operating features. It determines the size of a water body in which the system can be used, while guaranteeing vessels’ navigation safety. The DGPS system in the LF/MF range is now the basic positioning system in coastal waters around the world, which guarantees not only metre positioning accuracy, but it is also the only one to provide navigators with signals on positioning reliability. This paper describes and summarises over twenty years of studies dealing with the operating zone of the Polish DGPS reference station network. This paper is the fifth in a series of publications whose aim was to present in detail the process of installation, testing and long-term evaluation of the navigational parameters of the Polish DGPS system, launched in 1995. This paper includes the theoretical foundations of determination of the Dziwnów and Rozewie DGPS reference station operating zones in the years 1995-2018. Moreover, it presents the measurement results for the signal levels and the results of their analyses, which determine the station operating zones.

Opis:
Satellite measurement techniques have been used for many years in different types of human activity, including work related to staking out and making use of rail infrastructure. First and foremost, satellite techniques are applied to determine the tramway track course and to analyse the changes of its position during its operation. This paper proposes using the least squares with conditional equations method, known in geodesy (LSce). When applied, this method will allow for improvement of the final determination accuracy. This paper presents a simplified solution to the LSce alignment problem. The simplification involves replacement of the parameter binding equations with equivalent observational equations with properly selected weights. The results obtained with such a solution were demonstrated with a randomly selected section of a tramway track in Gdańsk. The article presents the theoretical foundations of the test method, the experiment organisation and the results obtained with MathCad Prime 3.0 software. It also presents the outcome of a study associated with the execution of the project No POIR.04.01.01-00-0017/17 entitled “Developing an innovative method of precision determination of a rail vehicle trajectory” executed by a consortium of the Gdańsk University of Technology and Gdynia Maritime University.

Opis:
Maintaining airway patency is an essential issue in many fields of medicine. The modern approach to CPR, which focuses on maintaining airway, breathing, and circulation was finally established by Peter Safar in his book ABC of Resuscitation (1950). At present, along with the development of evidence-based medicine, techniques which are proven to be clinically effective are regularly published in a convenient form – as bundles and guidelines. Regarding airway management, ERC and DAS guidelines are the most reliable and useful sources of knowledge and practical clinical advice. Among the medical staff, there is emphasis put on the mastery of AB C techniques. Airway management is the first step in the resuscitation algorithm. It consists of a variety of procedures ranging from simple and non-invasive to more complex, requiring professional training and experience. Currently, the most clinically effective and life-saving actions are incorporated into whole procedures and bundles, such as ERC or DAS guidelines, which are evenly checked, evaluated and, eventually, modified. This method of regular revision allows us to keep all medical professionals at the same level of competence. The aim of the study was to describe basic and advanced techniques, methods, and devices which are currently used to provide it. Currently applicable guidelines regarding CPR and airway management were reviewed and summarized.

Opis:
The autothermal termophilic aerobic digestion (ATAD) technology is used in the municipal and industrial wastewater treatment plants (WWTPs) with personal equivalent up to 30.000. The process provides a high level of sewage sludge stabilization and its hygienization. The main operation problems are caused by the high concentration of nitrogen and phosphorus in the reject water from sewage sludge treatment and air purification (odor removal). Reject water usually is returned to the main sewage treatment, which has a negative impact, especially on the sewage treatment systems based on the sequence batch reactors (SBR). Applying high-performance and expensive separate reject water treatment methods such as SHARON, Anammox or CANON in small facilities is not justified economically. The article presents the research results concerning the effectiveness of applying subsurface vertical flow constructed wetlands (SS VF) for reject water treatment from the ATAD process. An innovative type of bed filling was used, which was produced from waste (ash from a heat and power plant). The efficiency of reject water treatment during the research period was on average at 45.6% for ammonia nitrogen, 32.3% for total phosphorus and 85.1% for BOD5. Applying SS VF beds for separate reject water treatment might ensure a stable and effective functioning of municipal WWTPs by decreasing the load of biological part of a WWTP.

Mechaniczne zużycie szyn jest zjawiskiem znanym i opisywanym w literaturze, a także widocznym w torowisku dla postronnego obserwatora. Zelektryfikowanie prądem stałym transportu szynowego wywołuje w torowisku dodatkowe zagrożenia w stosunku do szyn. W literaturze technicznej istnieje wiele pozycji dotyczących oddziaływania prądów błądzących na podziemną metalową infrastrukturę oraz sposobom ochrony tych konstrukcji. W niniejszym artykule zwrócono uwagę na fakt, że prądy błądzące przyczyniają się również do zużycia – zmiany geometrii szyn – w miejscach innych niż główka szyny. Podano przykłady takiego zużycia oraz warunki jakie muszą wystąpić, aby skutki zjawiska prądów błądzących mogły się uwidocznić.
Mechanical wear of rails is a phenomenon known and described in the literature and also visible in the track for an outside observer. The electrification by direct current of rail transport causes additional hazards in the track in relation to the rails. In the technical literature, there are many items regarding the impact of currents straying on underground metal infrastructure and ways to protect these structures. In this work, attention is paid to the fact that stray currents also contribute to wear – changes in the geometry of rails – in places other than the rail head. Examples of such wear are given to the conditions that must occur in order for the effects of stray currents to become visible.

Opis:
The paper describes issues related to pressure drop that accompanies the phenomenon of maldistribution of working fluid between the channels of a model minichannel plate heat exchanger. The research concerns a single exchanger’s plate containing 51 (in every geometry) parallel rectangular minichannels of hydraulic diameters 461 µm, 571 µm, 750 µm, and 823 µm. In addition, more complex geometry has been investigated, equipped with additional diagonal channels (so called extended geometry). The moment of the liquid phase transition through the heat exchanger was recorded at the flow rates ranging from 0.83 g/s to 13.33 g/s in the inlet manifold. The paper discusses the total pressure drop as a function of the flow rate and the characteristic dimension of minichannels, as well as the pressure drop as a function of the time of the fluid passage through the main part of the measuring section in which measurements were done. The resulting profiles correlate with the images of the flow distribution between channels recorded using the fast shutter speed camera, that allows to draw a further conclusions about the specifics of the maldistribution process. The impact of the total pressure drop on the actual range of optimum operating conditions of the heat exchanger was analyzed.
