Opis:: Systematic analysis based on the assumption of rational behaviour of human being in addition to the mathematical models is based on the inherent factors in quantification of global risks. Decisions are made based on all available information, to act in order to maximize the utility. However, the current state of global quantification of risks based on the probability of economic loss scenarios, rationality of action in emergencies excludes and puts to the forefront scenarios likelihood and severity based on information asymmetry. If all risk takers were fully informed, it would avoid the moral hazard and the amount of individual risks would be stable in the global context.

Opis:: Nowadays, when we try to automatize all activities, there is a growing demand for energy in all forms. Increasingly we reach for new energy sources that can be problematic to store or to transport, owing to their toxicity or explosive propensity. The article examines the issues of determining danger zones occurring as a result of liquefied natural gas (LNG) release. The range of danger zones caused through LNG release depends on a multitude of factors. The basic parameter that needs to be considered is a type of the released substance as well as the manner of its release. The range of a danger zone is determined by, inter alia, the concentration of a released substance and the atmospheric conditions existing at the time when depressurization occurs. The article analyses the problem of the range of danger zones in a function of wind speed and surface roughness with a defined value of Pasquill stability for various LNG types, starting with pure methane, and ending with the so-called LNG-heavy. The difficulty of the task becomes more complicated when the analysed surface over which a depressurization incident takes place involves water. The problem deepens even further when the analysed substance possesses explosive properties. Then, apart from regular substance concentration, upper and lower flammability limit ought to be considered. Calculations were conducted with DNV-Phast software, version 7.11.

Opis:: The paper continues from previous joint studies and their practical application at the confluence of human geography, safety-related research and Geographic Information Systems (GIS). The objective of the study was to identify the land cover types most at risk from fire. The study has contributed an original angle by taking into account various land cover types with a potential influence on the distribution of fires geocoded at the address level. The analysis considered 27,651 fire interventions, as recorded by the Polish State Fire Service between 2014 and 2016 in the country’s central region known as Łódzkie Voivodeship. The main methods employed include various GIS tools, including Voronoi tessellation (to identify the areas most at risk of fire) and the fire location quotient (FLQ, a measure of the colocation between the number of fires and land cover). The most important conclusion is that of all the land cover types considered in the study, the built-up area type, especially the multi-family residential and retail and service area subtypes, was virtually the only one with a strong influence on the location of fires. The fire high-risk areas (FH-RA) identified here were primarily limited to urban areas.

Opis:: Kanalizacja podciśnieniowa jest rozwiązaniem o krótkiej historii w stosunku do powszechnie stosowanych systemów odprowadzających ścieki bytowo gospodarcze z budynków mieszkalnych. Jednak dzięki nowatorskiemu podejściu oraz zaangażowaniu się przedstawicieli świata nauki z Europy Zachodniej szybko stała się systemem, który zapewnia bardzo wygodny i bezpieczny transport ścieków bytowo-gospodarczych. Dzięki przyjętym rozwiązaniom zapewniającym praktycznie 100% szczelność systemu, kanalizacja podciśnieniowa jest rozwiązaniem, którego stosowanie wskazane jest w terenach zalewowych oraz o trudnych warunkach gruntowo-wodnych. Przykładem takiego zastosowania mogą być instalacje w całym świecie m.in. gminie Odolanów (południowa Wielkopolska).
The vacuum sewerage system is a relatively recently found solution in relation to the systems commonly used for discharging domestic sewage from residential buildings. However, due to an innovative approach and commitment of Western European scientific community representatives, it has quickly become a system, which provides very convenient and safe transportation of domestic and industrial wastewater. Thanks to the adopted solutions resulting in almost 100% tightness of the system, the vacuum sewerage is particularly suitable for use in floodplains and areas with difficult land-water conditions. Examples of such applications are installations found throughout the world, for instance in Odolanów municipality (Southern Wielkopolska).

Opis:: Podobieństwo układów wsi olęderskich oraz założeń wiejskich w Holandii jest wynikiem przeniesienia przez kolonistów rodzimych tradycji budowlanych, w tym również metod kształtowania rzeźby terenu. Specyficzne antropogeniczne formy ukształtowania terenu są charakterystyczne dla układów ruralistycznych lokowanych w dolinach rzecznych, gdzie występuje zagrożenie powodziowe. Zastosowanie terpów, wałów, rowów melioracyjnych zwiększa odporność na destrukcyjne działanie żywiołu w trakcie epizodów powodziowych. Przeprowadzona analiza wskazuje na potrzebę uwzględniania tych form przestrzennych, mających istotny wpływ na przyszłe funkcjonowanie obszarów osadnictwa olęderskiego, w trakcie prac rewitalizacyjnych czy planistycznych.
The resemblance of the olender settlement in Poland and the rural pattern of villages in Netherland is the result of native construction tradition transition by colonist, including methods of landform creation. Specific anthropogenic landforms are characteristic for rural patterns located in river valleys, where flood danger exists. The usage of terps, foodbanks, ditches increasing endurance of areas on the flood disaster. The research analysis shows necessity to include in revitalization or planning works that landforms, which has essential impact on functionality of olender settlement.

Opis:: Introduction: Stem cell-based therapies have shown promise in adults with ischemic cardiomyopathy and children with congenital heart diseases, especially those without available therapeutic options. Human neonatal mesenchymal stem cells (nMSCs) have greater regenerative potential than adult stem cells. Aim: To describe our experience with a novel catheter system for transcoronary delivery of cell-based therapies (CIRCULATE catheter) in the intra-coronary delivery of nMSCs in a swine acute myocardial infarct model. Material and methods: A newly developed catheter system (CIRCULATE catheter) with several unique features, including an expandable intra-coronary reservoir with spirally placed side holes of varying diameter, was used. nMSCs together with their secretome were used for the treatment. Pigs underwent myocardial infarction by inflating a 2.5 mm angioplasty balloon in the left anterior descending artery for 60 min. After reperfusion, stem cell therapy or placebo was administered via the novel catheter. TTE was performed at baseline, 1 h after the procedure, and before the euthanasia. Troponin blood concertation was evaluated at baseline, and after 48 h. The heart was harvested, sliced, and stained with triphenyl tetrazolium chloride (TTC). Infarct size to area-at-risk ratio was calculated. Troponin was assessed at baseline and after 48 h. Results: Thirty-nine pigs were operated with the mortality rate of 5.13% (exclusively malignant arrhythmia). Infarct size to area-at-risk ratio was significantly lower in the treatment group. Treated animals had higher ejection fraction than controls. Conclusions: Intra-coronary delivery of neonatal mesenchymal stem cells reduces the infarct size and restores myocardial function in a swine model. The novel catheter system (CIRCULATE catheter) tested in this study was safe and effective in transcoronary cell delivery of human neonatal mesenchymal stem cells.

Opis:: Ecological and geochemical indicators have been widely accepted as tools with the potential for rapid risk assessment of metal contamination of bottom sediments. In this study we propose a selection of such indicators to characterize the potential ecological risks stemming from metal contamination of the bottom sediments of the Chechło reservoir (S Poland). The Chechło reservoir is located in an area formerly occupied by zinc and lead ore mining and processing industry. High amounts of metals, especially zinc (39.37–4772.00 mg/kg d.m.), cadmium (0.37–21.13 mg/kg d.m.) and lead (4.50–434.49 mg/kg d.m.) have been found in the bottom sediments. Both geochemical (CD – contamination degree) and ecological indices (mean PECQ) were indicative of bottom sediment contamination and their potential toxicity to living organisms. Most of the bottom sediment samples (71%) examined were toxic for Heterocypris incongruens, while only 9% of the samples were toxic to Sinapis alba. However, no significant correlations between the metal content and the response of the test organisms were observed. Correlation and principal component analyses (PCA) showed that silt and clay fractions were the key factors influencing the metal content in the sediments. Our study makes a contribution to building evidence of the need to integrate several indices for the assessment of environmental risks related to the presence of metals in bottom sediments rather than relying on a single one.

Opis:: This study discusses the marine accident involving the Cosco Busan, the container ship that hit the base of the Delta Tower of the San Francisco-Oakland Bay Bridge in November 2007. An analysis of the elements resulting in the accident and its consequences has been carried out, followed by an analysis of the navigational risk using mathematical and tabular values. Mathematical values refer to the navigational risk in a specific sailing area, while tabular values refer to the navigational risk using a risk assessment. The main goal of this research was to identify and propose new measures that are correlated with a risk assessment. These measures should be applied in areas where an accident takes place so that future marine accidents can be reduced.

Opis:: Considering that approximately 20% of the nation’s land remains under the occupation of Russian forces, assessing the impact of the invasion in the midst of ongoing conflict is a formidable challenge. However, even the limited available data offers a distressing glimpse into an ecological catastrophe. The detonation of rockets and artillery shells leads to the generation of a variety of chemical compounds containing elements such as zinc (Zn), copper (Cu), lead (Pb), chromium (Cr), nickel (Ni), and cadmium (Cd). The primary goal of this research was to ascertain the presence of potentially hazardous elements (PTE) within the soil in areas subjected to targeted rocket attacks within the Lviv districts. Soil samples were gathered from four locations in the city of Lviv, which had been impacted by rocket fire, using a concentric circle sampling methodology. Two distinct instrumental techniques, namely X-ray fluorescence spectroscopy (XRF) and Inductively Coupled Plasma-Optical Emission Spectrometry (ICP-OES), were employed to quantify the concentration of heavy metals within the soil samples. Results revealed that all soil samples exhibited a significant exceedance of the maximum allowable concentrations for titanium (Ti), zinc (Zn), lead (Pb), and nickel (Ni). To assess the leachability and bioavailability of these elements within the soil, various extraction methods were applied in aqueous conditions and in the presence of ammonium citrate. The latter method demonstrated high effectiveness in extracting zinc (Zn), copper (Cu), chromium (Cr), and cadmium (Cd) from the soil. The level of soil contamination was evaluated using diverse criteria, including the contamination factor (Cf), the environmental risk factor (Er), the potential environmental risk index (Ri), the geoaccumulation index (Igeo), and the environmental risk factor (NIPI – National Iron plus Initiative). The computed cumulative environmental impact of all elements (NIPI = 49.001 and NIRI = 54.941, National Investor Relations Institute) underscores the substantial pollution within the surveyed area.
