Secondary Metabolites of Pathogenic Fungi in Triticum durum Grain Protected with Debaryomyces hansenii in Two Different Locations in Poland

Durum wheat grain can accumulate mycotoxins because it is highly sensitive to infections caused by pathogens of the genera Fusarium and Alternaria. Reduced fungicide use increases the demand for biological methods of pathogen control. The aim of the experiment was to evaluate the efficacy of Debaryomyces hansenii (Dh) yeast in reducing the content of secondary fungal metabolites present in the spikes of five durum wheat cultivars grown in southern and northern Poland. A total of 27 Fusarium metabolites and nine metabolites produced by other fungi were identified in the grain. The application of the Dh yeast strain decreased deoxynivalenol concentration in all samples relative to control treatments (by 14–100%) and treatments inoculated with F. graminearum (by 23–100%). In northern Poland, the biological treatment also led to a considerable reduction in the content of culmorin (by 83.2–100%) and enniatins A1 and B (by 9.5–65.3% and 6.7–70%, respectively) in the grain. An analysis of multiple fungal metabolites is a highly useful tool for determining grain quality and its suitability for consumption. When applied in the flowering stage, yeasts can partly complete fungicides in reducing Fusarium head blight.

Biological Properties of 12 Newly Isolated Acinetobacter baumannii-Specific Bacteriophages.

Infections with the opportunistic Gram-negative bacterium Acinetobacter baumannii pose a serious threat today, which is aggravated by the growing problem of multi-drug resistance among bacteria, caused by the overuse of antibiotics. Treatment of infections caused by antibiotic-resistant A. baumannii strains with the use of phage therapy is not only a promising alternative, but sometimes the only option. Therefore, phages specific for clinical multi-drug resistant A. baumannii were searched for in environmental, municipal, and hospital wastewater samples collected from different locations in Poland. The conducted research allowed us to determine the biological properties and morphology of the tested phages. As a result of our research, 12 phages specific for A. baumannii, 11 of which turned out to be temperate and only one lytic, were isolated. Their lytic spectra ranged from 11 to 75%. The plaques formed by most phages were small and transparent, while one of them formed relatively large plaques with a clearly marked 'halo' effect. Based on Transmission Electron Microscopy (TEM), most of our phages have been classified as siphoviruses (only one phage was classified as a podovirus). All phages have icosahedral capsid symmetry, and 11 of them have a long tail. Optimal multiplicity of infections (MOIs) and the adsorption rate were also determined. MOI values varied depending on the phage-from 0.001 to 10. Based on similarities to known bacteriophages, our A. baumannii-specific phages have been proposed to belong to the Beijerinckvirinae and Junivirinae subfamilies. This study provides an additional tool in the fight against this important pathogen and may boost the interest in phage therapy as an alternative and supplement to the current antibiotics.

Study of Polonium (210Po) Activity Concentration in Fruit Wines Derived from Different Locations in Poland.

This study aimed at assessing the activity concentration and the annual effective dose of polonium-210 (210Po) in fruit wines derived from four locations in Poland (Warmian-Masurian, Podlaskie, Lubelskie and Małopolskie voivodeships). The fruit wines differed significantly (p < 0.05) in 210Po activity depending on the production site, with the Małopolskie site having the highest activity (61.4-221.4 mBq/L) and the Podlaskie having the lowest (3.5-97.1 mBq/L). The site differentiation was due to environmental conditions-soil parameters (uranium concentration), precipitations and terrain characteristics, e.g., the proximity of the lakes. The increased activity concentration of 210Po in samples from Małopolska compared with the other sites probably derived from the environment polluted with aqueous wastes and particulate air pollution. The annual effective dose due to the ingestion of fruit wines ranged from 0.112 to 1.214 µSv/year. These levels of exposure are safe according to the WHO criterion (0.1 mSv per year for ingestion) and to the IAEA reference level for public exposure including food (1 mSv per year). Summing up, the data obtained provide information on the activity concentration of 210Po in fruit wines and increase databases on the natural radioactivity of foodstuffs. Future work is needed to examine 210Po activity in samples from all vineyard regions in Poland.

Antinutritional Nitrogen Compounds Content in Potato (Solanum tuberosum L.) Tubers Depending on the Genotype and Production System

This experiment analyzed the effect of genetic determinants, the production technology, and the location on the nitrate and nitrites content in potato tubers directly after harvest. Nitrates and nitrites are anti-nutritional compounds, which limit or prevent the use of nutrients from consumed products and have a detrimental effect on the human body. The study was conducted on seven tetraploid potato (Solanum tuberosum L.) clones (‘13-VIII-10’, ‘13-VIII-27’, ‘13-VIII-45’, ‘13-VIII-49’, ‘13-VIII-50’, ‘13-VIII-60’, ‘TG-97–403’), and three cultivars (‘Jelly’, ‘Satina’, and ‘Tajfun’) at four locations in Poland under either an integrated (Młochów, Boguchwała) or organic (Radzików, Chwałowice) production system. The results showed that the production system, location, and year significantly affected the nitrate and nitrites content in potatoes. Potato tubers originating from organic farming exhibited a lower content of the tested compounds (NO3−—124.1 mg kg−1 FW; NO2−—2.4 mg kg−1 FW) than that in the tubers obtained from an integrated production system (NO3−—203.7 mg kg−1 FW, NO2−—4.0 mg kg−1 FW). Under conditions of moderate stress as usual in the case of organic farming, the production of nitrates and nitrites are significantly lower than in the integrated production system. In our research potatoes from an integrated production system were characterised by a nitrate content at the limit of the established standard, i.e., 200 mg kg−1 FW. Tubers from the locality Chwałowice were characterised by the lowest nitrates and nitrites content, due to adequate environmental conditions, in addition to the best agricultural practice. The nitrates content depended to a greater extent on the environmental conditions than the potato on the genetic conditions. A higher content of nitrates and nitrites was found in the following potato clone 13-VIII-10 in Boguchwała from an integrated production system (NO3−—269.2 mg kg−1 F; NO2−—6.0 mg kg−1 FW), and in the ‘Tajfun’ cultivar (235.8; 5.8 mg kg−1 FW, respectively). Such a relationship was not found in integrated production in Młochów, which indicates the influence of the environment.

Divergent or convergent? Prioritization and spatial representation of ecosystem services as perceived by conservation professionals and local leaders

Application of the ecosystem services (ES) concept in policy and decision-making is one of the prime endeavors in conservation and land use planning. Previous studies call for a meaningful inclusion of different stakeholders in decision-making processes. One of the solutions that emerged to address these two aspirations is participatory mapping of ES. It enables the inclusion of different perspectives, knowledge, needs, or values into decision-making and has already been applied in various contexts. However, little is known about the similarities and differences between stakeholder groups reflecting on the same specific area. This study aimed to identify and explore differences in the conceptualization and application of the ES concept by two groups of stakeholders – experts and local leaders. The study was conducted in five locations in Poland and included 100 participants overall. At each site, we organized two workshops. One included nature conservation and spatial planning professionals, and the other non-professional local leaders. The results exhibit a new perspective on the comprehending of the ES by conservation and spatial planning stakeholders. The study unveils that the ES conceptualization and reasoning behind their prioritization tend to be convergent for both studied groups. Also the three approaches to mapping ES provisioning areas that we identified were used parallelly by both studied groups. The extent to which the resulting maps overlap depends on respondents’ interpretation of a mapped ES and the approach to mapping taken by a particular group. Both conservation professionals and local leaders included facts and values when applying the ES concept in practice.

The Microbial Community of the Respiratory Tract of Commercial Chickens and Turkeys.

Respiratory tract health critically affects the performance of commercial poultry. This report presents data on the microbial community in these organs from a comprehensive study of laying chickens and turkey breeders. The main objective was to characterize and compare the compositions of the respiratory system bacteria isolated from birds of different ages and geographical locations in Poland. Using samples from 28 turkey and 26 chicken flocks, the microbial community was determined by 16S ribosomal RNA sequencing. There was great variability between flocks. The diversity and abundance of upper respiratory tract (URT) bacteria was greater in chickens than in turkeys. At the phyla level, the URT of the chickens was heavily colonized by Proteobacteria, which represented 66.4% of the total microbiota, while in turkeys, this phylum constituted 42.6% of all bacteria. Firmicutes bacteria were more abundant in turkeys (43.2%) than in chickens (24.1%). The comparison of the respiratory tracts at the family and genus levels showed the diversity and abundance of amplicon sequence variants (ASV) differing markedly between the species. Potentially pathogenic bacteria ASV were identified in the respiratory tract, which are not always associated with clinical signs, but may affect bird productivity and performance. The data obtained, including characterization of the bacterial composition found in the respiratory system, may be useful for developing effective interventions strategies to improve production performance and prevent and control disease in commercial laying chickens and turkeys.

Greening of the District Heating Systems—Case Study of Local Systems

The integration of renewable energy resources into district heating systems is gaining momentum across Europe, as heat producers are expected to work towards the EU Directive of Efficient District Heating and Cooling to achieve carbon neutrality by 2050. This paper studies the techno-economic implications of transforming conventional district heating systems of six locations in Poland, generating 8.5 PJ of heat annually, into sustainable and efficient district heating systems. These new systems consist of flat solar collectors integrated with seasonal pit thermal energy storages and gas heating plants, acting as flexible heat sources, covering residual heat demand and/or increasing the parameters of the working medium in the network. Using the IEA-TIMES software, two scenarios were considered, namely STAT and DYN. The results show that reaching a 20% share of heat production by solar thermal would demand extra construction of seasonal heat storage facilities with a total capacity of 197 TJ, which is approximately 4.5 times bigger than the largest seasonal heat storage located in Vojens, Denmark. The projected increase in the prices of natural gas and CO2 emission allowances accelerates the transformation of systems towards greater use of solar heating plants. In the period 2025–2050 the heat generation costs increase by ca. 65%. The contribution of the CAPEX and OPEX costs components are presented.

What hides in the beach sand? A multiproxy approach and new textural code to recognition of beach evolution on the southern and eastern Baltic Sea coast

Sand beaches occur along the southern and eastern coasts of the Baltic Sea, and their sediments serve as an excellent archive of the past environment. In this study, we explore four beach locations in Poland and Latvia, taking a special interest in their sediments at the microscale. We determine sediment properties, potential extreme event records and type of transportation by applying grain-size analysis, and analysis of shape and character of sand grain surfaces under a binocular microscope and in a Camsizer M1 automated particle shape analyser, followed by statistical analysis. For a large dataset (of grains), the statistical approach reveals sediment grain characteristics that are hidden when looking at results in a traditional way. This approach allows a new textural code to be proposed that helps identify beach evolution and sedimentary environment conditions. Additionally, we define the threshold sphericity values for incidental storm records, and conversely, for long-lasting transportation and mature beach sediments, which are 0.8 and 0.9228, respectively. Both the textural code and threshold values can be utilised in sandy beach settings elsewhere. All in all, we detect (1) beaches with mature sediments that have experienced long-lasting transportation and reworking, (2) beaches and ancient beach ridges with medium sediment reworking and sediment mixing due to medium transport duration and pedestrian traffic, respectively, and (3) beaches that combine records of incidental storm events with grain inheritance from pre-Quaternary environments.

Methodology for the Determination of a Process Safety Culture Index and Safety Culture Maturity Level in Industries.

A mature of safety culture is crucial to preventing and mitigating accidents, incidents, and unsafe behaviors in the process industry, so as to make it more sustainable and economically responsible. Measurement, investigation, and assessment of the safety culture using interviews, questionnaires, behavior observation, reviewing documentation, and its impact on the safety performances of an organization is complicated, challenging, and requires a commitment to all employees. The aim of this study was to propose a novel, unique semi-quantitative methodology for the determination of a total process safety culture index and parametric model of process safety culture maturity in an organization based on the Bradley model. The methodology includes a questionnaire concerning different process safety culture factors, calculation procedures, and a graphical tool. In addition, three quantitative survey indicators were proposed: indicators of direct communication, average communication time, and the applicability rate of the proposed changes by employees. A fully-developed total process safety culture index allows for identifying, hierarchizing, and benchmarking different factors of the safety culture among companies and sectors. Moreover, it will enable identifying the area of actions required to improve safety practices and elements applied to the organization analyzed. The proposed methodology was verified in a case study of one energy company with three locations in Poland and can be easily applied to different industrial fields, including logistics and warehousing, the food industry, the paper industry, security services, fire services, and environmental and other agencies.

Applying TOPSIS to evaluate labour market resources as a factor of regional investment attractiveness

Investment attractiveness, defined as the ability to induce investors to choose a particular location for investment, plays a key role in the process of foreign direct investment inflow to the host country, also regarding its individual regions. The investment attractiveness is determined by an optimal combination of numerous factors, including resources and labour costs. This article evaluates labour market resources on a regional basis and, using the TOPSIS method (Technique for Order Preference by Similarity to Ideal Solution) that permits ordering of decision variants in terms of their similarity to the benchmark, being the most desirable alternative, a ranking of provinces was made in this respect for 2012, 2016 and 2020. The results of the study may be useful in the decision-making process concerning the choice of investment location in Poland by companies involved in foreign direct investment (FDI).

Waste Heat Recovery by Air-to-Water Heat Pump from Exhausted Ventilating Air for Heating of Multi-Family Residential Buildings

The paper presents an analysis of the application of an air-to-water electric compressor heat pump (AWHP) for the recovery of waste heat from the exhaust air in a typical multifamily residential building and the use of this heat for space heating, as well as the impact of this solution on the building energy performance (the PPR index). Simulations were performed in TRNSYS for five locations in Poland (Koszalin, Wrocław, Lublin, Białystok, Suwałki), for various heating system parameters (80/60 °C, 75/65 °C, 70/50 °C, 55/45 °C, 35/28 °C), for various temperature limitations of heat pump operation. It was shown that the analyzed system has great potential from an energy and environmental point of view. It can provide significant benefits in terms of the energy performance of the building, depending on the system parameters. The results show that the most energy-efficient system is the one with the lowest heating system temperatures. Moreover, implementing a temperature limitation on the heat pump operation improves its efficiency, but the higher the design parameters of the heating installation and the lower the limitation, the lower the heat pump contribution, and the higher the SCOP and the PPR. The energy effect is also influenced by location, but its scale depends on the parameters of the heating system and the temperature limitation of the heat pump’s operation. It is more significant for lower heating system parameters. This system enables the possibility of further reducing the demand for nonrenewable primary energy by powering the heat pump with photovoltaic cells.

Strength Properties of Structural Glulam Manufactured from Pine (Pinus sylvestris L.) Side Boards.

The aim of this study was to assess the static bending strength of pine glulam manufactured when obtaining the main yield, i.e., structural timber or timber to be used in the production of structural glulam. Analyses were conducted on pine timber harvested from three different locations in Poland. Two beam variants were manufactured, differing in the timber arrangement, horizontal vs. vertical. It was shown that the static bending strength of beams manufactured in the vertical timber arrangement variant is slightly higher than that of beams produced from horizontally arranged layers, with the latter beams characterised by a smaller confidence interval for this strength. Moreover, it was found that the difference in the value of the 5th percentile for both beam types is slight and both beam types are considered to exhibit a high bending strength of over 40 N/mm2.

Vernacular historical practices on Holocaust non-sites of memory in Poland

The approach employed by memory activists to sites of memory often involves historical practices. This paper presents the results of the examination of historical practices undertaken in locations of Holocaust violence during World War II and the disposal of victims’ remains that were not memorialised properly according to local residents or other groups with an interest in the sites’ past. The analysed practices were observed in the course of field research in various locations in Poland. The goal of the research was to describe these practices, discuss their critical potential, and indicate their distinct features as activities pertaining to contested sites of memory. A central tool for approaching this task is found in concepts of “non-site of memory” and “vernacular historian” as introduced to the debate by Claude Lanzmann and Lyle Dick. As a result, the article presents the cases of four vernacular historians whose practices are experimental combinations of the components of the work of professional historians and ways of working conditioned by local cultural environments, individual experience and commitment to communal life. Although vernacular history is sometimes considered of little value by academic historians, the research shows that the practices in question have the potential to produce new, socially relevant knowledge. Two distinct features of vernacular historical practices in non-sites of memory were observed: these unmarked sites of burial attract activists and prompt them to undertake historical practices; vernacular historians of these locations often undertake unconventional, sometimes experimental activities..

Measurement and Analysis of Infrasound Signals Generated by Operation of High-Power Wind Turbines

The development of wind energy and the increasing number of installed wind turbines make it necessary to assess them in terms of the nuisance of the emitted infrasound noise generated by such devices. The article presents the results of measurements and analyses of infrasound emitted during the operation of wind turbines installed in various locations in Poland. Comparative analysis of noise levels in the infrasound and audible range has shown that acoustic energy is mainly in the low and infrasound frequency range, and the measured levels depend significantly on the weighting curves used. On the basis of the results, it was confirmed that the sound pressure level of infrasound signals emitted by the operation of high-power wind turbines, regardless of wind velocity, weather conditions, design solutions of turbines, operating time, rated capacity, does not exceed the criteria specified in the applicable legislation dealing with the assessment of infrasound noise on the working environment.

Neighbourhood cohesion and territorial cohesion: in search for conceptual integrity

Neighbourhood cohesion is a concept describing the residents’ sense of community, engagement in acts of neighbouring, and attractiveness of living in the neighbourhood. Since 2000’s the term ‘cohesion’ has also been used in geography and in spatial policy to represent the distribution of functions and opportunities in space. The two approaches seem be complementary, but they lack consistency and appropriate conceptual framework. This paper aims at developing an integrated methodological framework which will include both social and spatial aspects of cohesion at the local level. Its empirical content refers to studies conducted in 2017–2019 in five locations in Poland. Three methods of spatial analysis are presented depicting various aspects of territorial cohesion of a neighbourhood: functional balance, accessibility of facilities and match between supply and demand. Such approach enables effective measurement and comparison of neighbourhoods representing various settlement types. The results show that the highest levels of cohesion were obtained for large cities where the density of amenities is the highest, and the lowest levels were noted in suburban settlements which confirms their malfunctioning character. The paper concludes with a critical revision of the concept of neighbourhood cohesion which can serve as a guideline for local urban policy.

New Pathotype Nomenclature for Better Characterisation the Virulence and Diversity of Blumeria graminis f.sp. avenae Populations

Fungal cereal pathogens, including Blumeria graminis f.sp. avenae, have the ability to adapt to specific conditions, which in turn leads to overcoming host resistance. An important aspect is the standardized way of characterizing the races and pathotypes of the pathogen. In the presented work, for the first time it was proposed to use a unified letter code that allows describing the pathotypes of B. graminis f.sp. avenae. The set of 14 oat genotypes were used as a differential set. This set included genotypes having so far described powdery mildew resistance genes Pm1–Pm11, and two genotypes (A. sterilis and A. strigosa) with effective sources of resistance to Bga. Based on the analysis of 160 Bga isolates collected in 2016–2019 from 4 locations in Poland, the most numerous was the TBBB pathotype, represented by 30% of the tested isolates. It was present in all analyzed populations. Subsequently, 8.1% and 6.3% of the isolates represented the TBCB and RBBB pathotypes, respectively.

Bioactive Components, Volatile Profile and In Vitro Antioxidative Properties of Taxus baccata L. Red Arils.

This study aimed at assessing the composition of bioactive compounds, including ascorbic acid, carotenoids and polyphenols, the volatile compound profile and the antioxidant activity of red arils (RAs) of Taxus baccata L. grown in diverse locations in Poland. Among the carotenoids assayed in high quantities (3.3–5.42 μg/g), the lycopene content (2.55–4.1 μg/g) was remarkably higher than that in many cultivated fruits. Samples collected from three sites were distinguished by higher amounts of ascorbic acid (125 mg/100 g, on average) than those found in many cultivated berries. Phenylpropanoids quantitatively dominated among the four groups of phenolic compounds. Chromatographic separation enabled the detection of two phenylpropanoid acids: ferulic and p-coumaric. Irrespectively of the growth site, RAs contained substantial amounts of (-)-epicatechin (1080 μg/100 g, on average). A higher ability to scavenge DPPH● and ABTS●+ radicals was found in the hydrophilic fraction of RAs from two sites (Warsaw and Koszalin) compared with the other two sites. The volatile compound profile of RAs was dominated by alcohols, followed by ketones, esters and aldehydes. The presence of some volatiles was exclusively related to the specific growth site, which may be regarded as a valuable indicator. The combination of bioactive and volatile compounds and the fairly good antioxidant potential of RAs render them an attractive source for preparing functional foods.

Air Pollution Observations in Selected Locations in Poland during the Lockdown Related to COVID-19

The coronavirus disease (COVID-19) has caused huge changes in people’s daily habits and had a significant impact on the economy. The lockdowns significantly reduced road traffic and meant that many people worked remotely. Therefore, the question arose as to how the reduced road traffic and stays of residents at home affected the degree of pollution and the structure of major air pollutants. To answer this question, the article presents an analysis of changes in typical air pollutants (PM10, PM2.5, NO2) in the five largest Polish cities and one of the voivodships. The data from the Polish State Environmental Monitoring were used for the analysis. The analysis showed that the period of the first lockdown in Poland (April 2020), despite the reduced road traffic, resulted in a significant increase in PM10 emissions (9–91% during working days and an average of 30% on Saturdays and Sundays), a slight increase in PM2.5 emissions (on average from 2% to 11% for all analyzed locations), and a reduction in NO2 emissions (on average from 6% to 11% for all analyzed locations) compared to the period before the lockdown. However, the changes were not homogeneous—in Łódź and Warsaw, in most cases, an increase in all analyzed pollutants was observed, and the greatest decrease in pollution took place in Małopolska voivodship (including Kraków). Comparing the data from April 2020 to the data from April 2019, the overall difference in the PMs concentrations was small, although there are places where there has been a significant decrease (Wrocław, Poznań), and there were also places where the concentration increased (Warsaw, Łódź, Małopolska). In the case of nitrogen dioxide, pollution concentration decreased in most locations. The only exception was the background stations in Warsaw, where the increase was 27%.

An Energy Efficiency Estimation Procedure for Small Wind Turbines at Chosen Locations in Poland

Contrary to the extensive amount of research on large wind turbines, substantial analyses of small wind turbines are still rare. In the present study, the wind energy potential of three locations in Poland is analyzed using real wind data from a five-year period and the parameters of the selected turbine model. Appropriate simulations are performed to assess the energy efficiency of the analyzed investments at a coastal, foothill, or lowland site. According to the results, the most favorable location for a small wind turbine is the coastal site (wind zone I). The payback time at this location is approximately 13 years, whereas the payback times at the other two analyzed are more than 3 times longer. The payback periods for the latter locations significantly exceed the estimated lifetime of the wind turbine, ruling out their economic viability. The cost of electricity generation varies greatly, from 0.16 EUR/kWh at the coastal location to 0.71 EUR/kWh at the lowland location. These results provide a reference for developing more efficient solutions, such as the use of a turbine with a shielded rotor, which can increase the power of the turbine by approximately 2.5 times.

Relationship between concentrations of elements and geographic location in Poland.

Interactions occur between concentrations of metals in the human body and the environment in various geographic locations, which can be of importance for both the proper development and the course of pregnancy. The aim of the study was to assess the concentrations of Zn, Cu and Cd and Zn:Cu and Zn:Cd molar ratios in the placenta, umbilical cord and in the foetal membrane, and to examine the relationship between concentrations of these elements and the place of residence. The research material was obtained from 99 healthy women from north-western and central Poland. Data for the study were collected from the medical history and documents of admission to the ward and documents confirming the birth of the newborn. Concentrations of zinc (Zn), copper (Cu) and cadmium (Cd) were determined using the ICP-AES method (spectrophotometry of atomic absorption) in inductively coupled argon plasma. The average concentration of Zn, Cu and Cd in afterbirths was ~ 0.01 mg/kg of dry weight (dw). In central Poland, the results revealed a significant increase in zinc in the membrane (OR=1.098, p=0.002), cadmium in the placenta (OR=1.324, p=0.006), Zn:Cu in the membrane (OR=1.012, p<0.001). In north-western Poland, an increase in copper in the membrane (OR=1.239, p=0.025) was revealed. The use biological materials, such as the placenta, foetal membrane and umbilical cord to assess exposure to heavy metals and necessary elements is justified.
