Published: January 2021

Abstract
Fungal diseases are a persistent problem in the cultivation of white button mushrooms (Agaricus bisporus). The chemical control of pathogens is becoming less effective and less desirable, so new ways to limit these infections are urgently required. What is more, the disease is mostly controlled through cultural practices and good hygiene on mushroom farms. The aim of this study was to evaluate the fungicidal effects of ozone on fungal pathogens of common mushrooms. Experiments with the use of ozone gas for disinfection of growing rooms after the completion of the mushroom growing cycle were carried out. The fungicidal effectiveness of ozone fumigation was evaluated on the basis of the survival rate of the spores of the pathogens tested (Lecanicillium fungicola, Cladobotryum dendroides, Mycogone perniciosa, and Trichoderma aggressivum). Spore suspension was applied to aluminum plates and then was exposed to gaseous ozone. The assessment of the growth of colonies of fungal isolates obtained from infected surfaces was carried out using Rodac contact test plates. The results showed that L. fungicola, M. perniciosa, and C. dendroides isolates were sensitive to the gas ozone. In order to achieve 100% efficacy against Mycogone strains, a minimum of 6 hours of ozonation had to be applied, whereas for Cladobotryum strains, a minimum of 8 hours had to be applied. The Lecanicillium species was the most sensitive to ozonation because 30 minutes of ozonation was enough to gain 100% inhibition of its growth. No satisfactory results were obtained in the case of the pathogenic species of Trichoderma, regardless of the experimental conditions. Nevertheless, this study has demonstrated the usefulness of ozone as a disinfectant for empty growing rooms after the completion of the mushrooms’ cultivation cycle.

Abstract
China aster and gaillardia are flowering plants with high economic importance in floriculture. In the present investigation, response of China aster and gaillardia seedlings to inoculation with the arbuscular mycorrhizal fungus Funneliformis mosseae + the plant growth-promoting rhizobacterium Bacillus sonorensis was studied by growing in multipots (pro trays). The germination percentage and plant growth parameters: length of shoots, roots and whole seedlings, stem diameter, biovolume index, plant strength, vigor index, dry weight and nutrient uptake, were analyzed 60 days after sowing. The microbial parameters, mycorrhizal root colonization and spore count, and the population of B. sonorensis in the substrate were also determined. The results brought out that growth of inoculated seedlings was significantly improved as compared to uninoculated seedlings. Based on the plant growth and microbial parameters studied, it was concluded that inoculating the substrate in pro trays with the microbial consortium results in producing vigorously growing seedlings.

Abstract
The democratisation of national defence policies and systems plays a vital role in making any country more democratic. The democratic transition of this sector in Slovenia and Montenegro has experienced a challenging reform process and it is now time for reflection. This paper aims to identify the main characteristics and issues of the democratisation process in the field of national defence in both countries and, by comparing them, to look for key similarities and differences. The paper argues and confirms that the Slovenian and Montenegrin national defence and security systems were initially faced with serious post-socialist democratic deficits, but gradual democratisation then brought drastic improvements to the quality of their democracy. The process of joining NATO and the change from a military threat perception to a non-military threat perception created space for many reforms. Greatest steps forward in democratisation in both countries entailed nominating civilian defence ministers, having a reasonable number of civilian defence experts involved in the military business, establishing working parliamentary monitoring committees, reducing defence budgets and reallocating funding to other sectors. Progress was also observed in reducing the total number of soldiers, establishing a fully professional armed force, assuring that women in the armed forces were properly represented and increasing the deployment of soldiers to foreign stabilisation operations in a sign of becoming security providers.

Authors: Postnikov Ivan 
Published: January 2021

Abstract
The general idea of the methodology for the comprehensive reliability analysis of district heating systems (DHS), developed earlier by the author of this paper, is a joint considering and modelling of each technological processes, including fuel supply to heat sources (HS), generation of heat energy by these HS and its distribution on district heating network (HN). For solving this problem different methods and models are applied: statistical testing method, Markov random processes, methods of the theory of hydraulic circuits, basic laws of district heating and heat transfer processes, etc. In this paper the main attention is paid to the results of the practical application of methods and models of a comprehensive reliability analysis of DHS using the example of calculations performed for the actual DHS scheme of the Shelekhov city (Irkutsk region, Russia). Different stages of the case study are considered, including preparation of initial data, simulation modelling of fuel supply to HS, modelling of the Markov random process describing operate of DHS, calculation of post-failure modes in HN, evaluation of nodal reliability indices (RI), decomposition analysis of reliability. Based on the analysis of calculation results some preliminary directions are formulated to the increase of reliability for studied DHS. These data are the basis for a comprehensive reliability synthesis (optimization) of DHS, the solution of which is the subject of special perspective stage in development of the research.

Published: January 2021

Abstract
Water quality in small agricultural catchments is affected by anthropogenic (crops, field management operations, fertilizer application) and natural (soil texture, topography, meteorological and hydrological conditions) factors. It is important to estimate long-term (1995–2018) trends of nitrogen losses from small agricultural catchments and subsurface drainage fields to surface water bodies in order to evaluate the impacts of anthropogenic and natural factors and to cover management needs such as implementation of national legislation and the EU directives. The content of the Common Agricultural Policy is currently under development, therefore, there is a need to consider existing monitoring results to address water quality goals within the next planning period. This study examines temporal trends in water discharge, total nitrogen (TN) and nitrate–nitrogen (NO3-N) concentrations and losses from three agricultural runoff monitoring sites in Latvia including Berze, Mellupite, and Vienziemite. The yearly data series of TN and NO3-N concentrations and loss were tested for statistical trends using the Mann-Kendall test. The study results show high variations in TN and NO3-N concentrations and losses among monitoring sites both in subsurface drainage field and small catchment scale. For TN and NO3-N losses five out of six monitoring sites showed an upward trend, while for TN concentrations three out of six monitoring sites and NO3-N four out of six monitoring sites showed an upward trend. The results of this study indicate that the upward trends in TN losses are affected by hydrological conditions at the study sites.

Published: January 2021

Abstract
The aim of this study is to prove technical feasibility of combined refuse derived fuel (RDF) torrefaction and oily wastewater treatment approach by using RDF derived biochar as a sorption media. Biochars prepared from refuse derived fuels in torrefaction, carbonization and pyrolysis modes were analysed as fuels and as hydrocarbon sorbents. Changes of elemental composition and properties of material during thermal treatment and subsequent washing process have been analysed. Experimental evaluation of sorption behaviour of toluene and diesel fuel on obtained biochar performed. Our results show that torrefaction/carbonization of RDF coupled with the subsequent washing of biochar is a method allowing to overcome absolute majority of the quality problems of waste derived fuels, including the most important one: high chlorine content. In spite the fact that optimal temperatures for upgrading waste derived fuels and to produce high quality sorbent does not coincide, technically it is possible to combine the washing of torrefied/carbonized waste derived fuels with the treatment of wastewaters that are polluted with oils or hydrocarbons.
Quantitative and Financial Aspects of Resilience Bonds in the Context of Recursive Insurance Contracts. A Cost Benefit Analysis

Published: January 2021

Abstract
It is now well known that the world community must share the risks and hazards deriving from climate change and, more generally, from the environment. At the end of summer 2019, the European Bank for Reconstruction and Development (EBRD) issued the World’s first dedicated climate resilience bond and this confirms the thesis according to which financial, social and economic instruments are always most necessary for the development of society and to avoid that natural hazards can, as occurred in the past, cause extremely heavy damage with negative repercussions on every single area of a community. Starting from the characteristics of resilience bonds and reinsurance, the paper seeks to highlight the potential advantages that would derive from a systematic application of recursive contractual instruments (smart contracts). The authors focused on the study of the projection of financial and quantitative data of resilience and catastrophe bonds on the basis of a determined timeline, a fixed insurance premium, mitigation works related and connected to the main contract (insurance). In particular, the study concerns the correlation of the urban implementation of risk mitigation works with the specific catastrophic flood risk. The paper implements a purely economic and social cost-benefit analysis (ACB) in the sense that includes, among others, a public approach and the goal of maximizing social welfare, according to efficiency economic criteria. In a nutshell, the authors highlight as the main result not only the possibility, but also the convenience of the joint and multidisciplinary application of the quantitative method (resilience bonds) to infrastructure resilience.

Abstract
Water contamination by various bacteria, viruses and other pathogens is a great threat to human health. Amongst other Advanced Oxidation Processes TiO2 photocatalysis is considered as one of the most efficient treatment for the polluted wastewater disinfection. Usually, the wastewater produced by higher risk objects, such as hospitals, implicates diverse contaminants, but efficiency of most of the Advanced Oxidation Processes is tested by using only single pathogens and information on inactivation of bacteria mixtures is still limited. In this study, photocatalytical inactivation of three commonly found bacterial pathogens (gram-positive (Micrococcus luteus) and gram-negative (Salmonella enterica, Escherichia coli)) was investigated. Efficiency of traditional photocatalytic disinfection process using single bacterial pathogens was compared to the one observed for their mixtures. The impact of photocatalytical process parameters and treatment time on bacteria disinfection efficiency was studied. Photocatalytic disinfection efficiency testing with bacteria mixtures revealed, that in the presence of TiO2 photocatalyst and UV irradiation tested gram-positive cells were inactivated slower than gram-negative cells. Another important finding was that an overall photocatalytic disinfection efficiency of bacteria mixtures is not a straight forward sum of inactivation rates of individually tested pathogens but has a strong relationship to the properties of their competitive growth.

Published: January 2021

Abstract
Large-scale heat pumps (HPs) and refrigeration plants are essential technologies to decarbonise the heating and cooling sector. District heating and cooling (DHC) can be supplied with low carbon footprint, if power generated from renewable energy sources is used. The simultaneous supply of DHC is often not considered in energy planning, nor the characteristics of the heat source and sink. Simplified approaches may not reveal the true potential of HPs and chillers. In this paper, different heat sources and sinks and their characteristics were considered for the simultaneous supply of DHC based on large-scale HPs and refrigeration plants. An optimization model was developed based on mixed-integer linear programming. The model is able to identify ideal production and storage capacities, heat sources and sinks based on realistic hourly operation profiles. By doing so, it is possible to identify the most economical or sustainable supply of DHC using electricity. The optimization model was applied to the Nordhavn area, a new development district of Copenhagen, Denmark. The results show that a combination of different heat sources and sinks is ideal for the case study. A HP that uses the district cooling network as a heat source to supply DHC was shown to be very efficient and economical. Groundwater and sewage water HPs were proposed for an economical supply of district heating. The Pareto frontier showed that a large reduction in annual CO2 emissions is possible for a relatively small increase in investments.

Published: January 2021

Abstract
Due to growing topicality of indirect land use change, greater shift towards second generation biofuels should be observed. In order to help smaller biogas and bioethanol producers, multi-criteria analysis of lignocellulose pre-treatment is conducted to elucidate the most preferable approach for lignocellulose pre-treatment. There are four main pre-treatment groups – biological, chemical, physical and physochemical pre-treatment. In this article three pre-treatment types were described by highlighting their specific approaches; using multi-criteria analysis a conclusion was reached that the most preferable pre-treatment option for lignocellulose biomass like corn stover or sugarcane is microbiological pre-treatment, as it showed the closest proximity to ideal solution.

Published: January 2021

Abstract
The Automated External Defibrillator (AED) is an intuitive device used by witnesses of an incident without medical training in cases of sudden cardiac arrest. Its operation consists in delivering an electrical pulse to the cardiac conduction system, as a result of which normal heart rate is restored. The lack of awareness in society concerning the usefulness of the device and the inadequate deployment of AEDs result in their too infrequent application by witnesses of incidents. The aim of this paper is to verify whether cluster analysis is the appropriate statistical method to determine the appropriate deployment of AED devices on the basis of cases of sudden cardiac arrest in out-of-hospital conditions. The initial cluster analysis showed the validity of using the method in question for planning the appropriate locations of AEDs.
Using “Text Mining” Analysis for the Assessment of the Health Quality of Dietary Supplements

Published: January 2021

Abstract
Techniques of text data analysis have been known for many years and commonly used in many areas of life. Text mining enables, among others, the acquisition of information from the text, its filtering, and studying of similarities and relationships. The aim of this paper is to design a method that would make it possible to assess the health quality of dietary supplements, on the basis of text mining techniques. A fictional plant-based product was used in the study, which was compared with other products containing at least one of the tested ingredients registered in the years 2007–2019 in the register of dietary supplements kept by the Chief Sanitary Inspectorate (GIS), which were given either the “consistent” or “to be clarified” status. The obtained results concern the frequency of occurrence of the individual ingredients (St John’s wort/Hypericum, melissa, rose root/Rhodiola) in other products, considering their status in the register. The data thus obtained was subjected to classical statistical analysis in order to find correlations between the presence of a given ingredient and the product status. In view of the obtained results, the text mining analysis may be considered as a helpful tool in the process of internal risk assessment performed by manufacturers of dietary supplements.

Published: January 2021

Abstract
Approx. 60–80 million couples globally are affected by the problem of infertility. The issue is important both for the couple trying to conceive and for the whole society in which the couple lives. Lifestyle, including nutrition, may have both a positive and a negative impact on the outcomes of infertility treatment. The aim of this paper is to assess the relationship between knowledge in the area of fertility diet and its actual use, and types of fertility disorders among women undergoing treatment in a fertility clinic. A group of women was analyzed statistically, divided into 3 groups according to their couple’s cause of infertility – the causes of infertility were described as: the male factor, the female factor, and the idiopathic factor. The study group answered questions that comprised a fertility diet knowledge test; the frequency of consumption of particular food products in a individual groups was also analyzed. Correspondence analysis showed differences between the groups in the number of points scored in the fertility diet knowledge test, as well as in the consumption of sweets, crisps and sticks, and nuts and seeds. Women among whom the main cause of infertility was defined as the male factor scored the highest numbers of points in the fertility diet knowledge test, women with the idiopathic cause of infertility scored slightly lower numbers of points, while women whose main cause of infertility was defined as the female factor scored the lowest numbers of points. Women from couples with idiopathic infertility consumed sweets, crisps and sticks the most often, followed by women with the cause of infertility identified on their side, with the lowest frequency of consumption of sweets identified among women whose partner was infertile. Nuts and seeds were consumed the most frequently by women whose partners were infertile, followed by women with the cause of infertility identified on their side, while women with the idiopathic cause of infertility consumed nuts and seeds the least frequently. These examples show that correspondence analysis is well suited to the assessment of the influence of lifestyle on fertility; in addition, it makes it possible to recognize certain correlations that may not be observed in standard statistical tests.

Published: January 2021

Abstract
The increase in suicidal behaviour among elderly people makes it necessary to take action in the field of broadly understood prevention. This includes helplines, which play an essential role in anti-suicidal measures. The aim of this study was to obtain information about the experience of Polish helpline workers in communicating with older people in suicidal crisis. The study was conducted among 106 helpline workers from various helpline centres across Poland. It proved that helpline workers in Poland have considerable experience in communicating with elderly people in suicidal crisis, albeit the majority of respondents feel they need additional training in the area of broadly understood suicidology.
