Opis:
In the process of shaping particular academic disciplines, there is a need to synthesise the existing research results and on their basis propose new methodological approaches and indicate the possibility of applying new directions of theoretic-cognitive and application research. This is the idea to which the theme and purpose of this paper refers. It proposes a new holistic research concept. The first part of the article reviews the hitherto research problems concerning the operation of an industrial plant (enterprise). Presented are the changing research concepts that initially treated the industrial plant as a landscape element, and then as a production plant affecting the processes of industry concentration, as well as socio-economic and cultural changes of the surroundings. In the second part, in the light of the theory of the dynamic system, the assumption was made that an industrial enterprise is not an isolated element of geographical space, but one of its functional components. Its role changes under the influence of endogenous and exogenous factors, as well as in the process of civilisation development. Using the idea of a dynamic system and the model of the functioning of geographical space, a new, holistic concept of research into the operation and development of an industrial enterprise is proposed. It includes various relationships: between the enterprise and the elements of geographical space (natural, socio-economic, cultural), between the rules of economic development, between different functional types of enterprises, competitive, between the categories of the environment, between the power elites and types of policies. The proposed model approach makes it possible to define various relations with the enterprise and allows for a comprehensive understanding of its functioning in a diversified surroundings, and it provides for the definition of a more precise strategy for its development.

Opis:
Ongoing pressure on prices for construction projects adds to the significance of cost estimation accuracy in building construction. Due to competition from Asian entrants, main contractors in the plant engineering industry are facing a similar situation. In the present paper, the cost estimation standards for industrial plant engineering are analyzed and compared with the respective standards for Building Construction (BC). In particular, cost estimation guidelines by the Association for the Advancement of Cost Engineering (AACE) are checked against a guideline known as the ‘cone of cost’ following the Official Scale of Fees for Services by Architects and Engineers (German: HOAI) for comparable phases of performance. It is shown that the plant engineering industry cost estimation guidelines are much more tolerant in terms of accuracy than the ones for Building Construction in Germany, especially in the early phases of a project. A set of possible reasons is identified and categorized by (1) competition intensity, technology impact and frequency of project occurrence, (2) demands on cost estimation professionals, (3) materials and supplies, (4) duration of project execution, (5) certainty of projected cash flows. Finally, the study marks starting points for further research: First, to use non-German BC estimation standards for the comparison, and second, to empirically validate and extend the set of reasons.
Trwający nacisk na ceny projektów budowlanych zwiększa znaczenie dokładności szacunku kosztów. Dotyczy to również głównych wykonawców z przemysłu maszynowego. W artykule przedstawiono standardy szacowania kosztów dla inżynierii zakładu przemysłowego. Wykonano je zgodnie z odpowiednimi standardami Building Construction. W artykule pokazano, że niemieckie wytyczne przemysłu maszynowego dotyczące szacowania kosztów są znacznie bardziej tolerancyjne niż dla budowania konstrukcji, szczególnie dla wczesnych etapów projektu. Zbiór możliwych powodów: (1) intensywność konkurencji, wpływ techniki 30 A. Erbe i częstotliwość zdarzenia projektu, (2) żądania w stosunku do profesjonalistów szacunku kosztów, (3) materiały i zaopatrzenie, (4) czas trwania projektu, (5) pewność przewidzianych przepływów gotówki.

Opis:
The power industry is one of the most water-consuming industries, therefore water management in this sector of the economy is a very important element of sustainable development. The analysis of the management of water streams at the surface water treatment plant (WTP) with decarbonization and ion exchange for water softening and demineralization was done. The main emphasis was placed on the effect of recycling of water used for the WTP’s own purposes on the quantity of water taken from the river and the quality of treated water. The article shows that water savings should also be sought at WTP in combined heat and power plants. Accurate distribution of used technological water streams and determination of their quality allows for the appropriate indication of the points of their return to the main technological line without additional treatment or only with the use of basic technological processes, e.g. sedimentation. In the analysed WTP, the quality of the backwash water returned after treatment was in terms of parameters, i.e. conductivity, hardness, alkalinity, CODKMnO4 and iron concentration, better than the quality of raw surface water. The reduction in the amount of water abstracted due to recycling of water treatment plant technological waters was about 8.3% (approximately 130 000 m3/year).

Opis:
The objective of the study was to perform micromorphological analyses of the secretory structures of leaves and stems of oil-bearing industrial plants from the Lamiaceae family such as lemon balm (Melissa officinalis L.), peppermint (Mentha × piperita L.), sage (Salvia officinalis L.), marjoram (Origanum majorana L., syn. Origanum dubium Boiss.), rosemary (Rosmarinus officinalis L.) and common thyme (Thymus vulgaris L.) using light microscope and scanning electron microscope. In addition, an estimation of the content of volatile substances in the plant species under study was performed using GC-MS, as well as the qualitative and quantitative analysis of essential oil, that is an important component in terms of the estimation of raw material applicability for use in the industry. In the epidermal cells of studied plants, 2 types of Lamiaceae-type glandular trichomes were identified: short- and long-stalked capitate glandular trichomes with single- and bicellular secretory capitulum, and peltate glandular trichomes with eight- and over a dozen-cell secretory capitulum. Capitate trichomes were densely distributed on the surface of the epidermis, while peltate trichomes were sparse, though regular, and were situated in depressions. Glandular trichomes were found more frequently on leaves than on stems. The cuticle of the abaxial of leaf was characterized in most cases by the occurrence of larger average diameter peltate trichomes compared to the cuticle of the adaxial side of leaf. Peppermint produced the largest structures accumulating essential oil on the leaves (average diameter of peltate trichomes – 78.48 µm on the adaxial side of leaf, up to 96.43 µm), while on the stem, the highest average diameter of the peltate trichomes was observed in sage (an average of 75.53 µm, up to 85.99 µm). The lemon balm was characterized by the presence of capitate and peltate trichomes with the smallest diameter (an average of 44.26 µm). Lemon balm was characterized by the greatest density of glandular trichomes compared to other plant species. Among the plants studied, the highest content of oil was noted in the case of thyme and peppermint (2.22% and 2.20% v/w, respectively), and the lowest in green parts of lemon balm (0.17% v/w). The isolated essential oils contained predominantly components from the groups of monoterpenes and sesquiterpenes, and it is the presence of those substances that determines the possibility of utilizing the plants studied for a variety of purposes.

Opis:
Phytoremediation is considered of a cost effective and environmentally friendly technology and has been used successfully for the remediation of soils and water contaminated with various pollutants. Specifically for full scale application to treat industrial wastewater, phytoremediation is used as sole technology for different types of wetlands. However, phytoremediation of polluted water in wetland type reactor has been mostly studied as black box. The method to measure the performance is only based on pollutant removal efficiency and there is very limited information available about of the pollutant removal mechanisms and process dynamics in these systems. Thus, the aim of this chapter was to briefly review basic processes of phytoremediation, its mechanisms and parameters, and its interaction between rhizo-remediation and microbe-plant. In addition, this chapter also elaborated phytoremediation challenges and strategies for full-scale application, its techniques to remove both organic and inorganic contaminants by aquatic plants in water, and some examples of applications in industries.

Coke oven battery is a complex and multifaceted facility in terms of air pollutant emissions. As far as stack or quenching tower does not cause major difficulties of emission measurement, the fugitive emission measurement from such sources as battery top elements (charging holes, ascension pipes) or oven doors is still complicated and not fully solved problem. This article presents the discussion concerning main problems and errors likely to be made in particular stages of procedure of fugitive emissions characterization from coke oven battery (selection of sampling points, sampling itself, measurement of air velocity over battery top and laboratory analyses). In addition, results of concentrations measurements of selected substances characteristic for the coking process (naphthalene, anthracene, 4 PAHs and TSP) originating from fugitive sources of coke oven battery and subjected to reporting under the E-PRTR are presented. The measurements were carried out on a coke oven battery top in points selected on the basis of the preceding detailed air convection velocity measurements over the battery top. The results of the velocity measurements were compared with results of numerical modelling using CFD software. The presented material is an attempt to cross-sectional presentation of issues related to the quantitative evaluation of fugitive emission from coke oven battery, discussed on the example of PAHs emission as a group of substances characteristic for coking of coal.

This study presents the results of examination of the vegetation on the waste landfill of ArcelorMittal-Warszawa steel mill and the furnace waste landfill of Siekierki Power Station, both sites in Warsaw. The presented analyses of the field research contain detailed floristic-phytosociological data as well as botanical and ecological evaluation of the identified plants. The vegetative structures, together with the succession trends of the vegetation cover of two examined landfills, have been shown. Ecological habitat adaptations of plants and their spatial structure have been evaluated. The inventoried flora has been subjected to taxonomic, syntaxonomic and ecological classification. 154 plant species from 48 taxones in the range of families have been identified. Families characterized by the biggest abundance of species were: Compositae, grasses and Fabaceae. More than half of the live forms indentified were hemicryptophytes. The vegetation of two landfills has been dominated by synantrophic communities (Stellarietea mediae, Artemisietea vulgaris, Molinio-Arrhenatheretea), with apophytes being in the largest number. With the use of ecological indicators a broad ecological tolerance of the majority of species toward ecological factors has been observed.

Opis:
This paper presents calculations based on results of a field experiment, in which selected potato cultivars grown for industrial processing received different fertilization. The data originated from trials on three potato cultivars: Adam, Pasja Pomorska and Ślęza, at set up at the Research Station in Bałcyny, owned by the University of Warmia and Mazury in Olsztyn, and completed in 2008-2010. The economic analysis included planned and performed treatments as well as such information as the type of technical equipment, labour and draught force input, or material outlays. Based on the analysis, it can be concluded that the three starch potato cultivars responded differently to foliar fertilization. The cv. Pasja Pomorska yielded the highest under soil fertilization with 280 kg·haˉ¹ NPK (80 N, 80 P, 120 K) and foliar application of Basfoliar 12-4-6 in a dose of 8 dm3·haˉ¹. Considering the ratio of the yields to costs, cv. Ślęza was characterized by the best profitability index, which in every technological variant reached a value of over 2.0. From the point of view of rational economy, the most profitable was the fertilization combination which consisted of soil fertilization with 420 kg·haˉ¹ NPK (120 N, 144 P, 156 K) and foliar application of Basfoliar 12-4-6 with Solubor DF in amounts of 4 + 1 dm³·haˉ¹.
W pracy zaprezentowano obliczenia będące wynikami doświadczenia polowego związanego z wpływem zróżnicowanego nawożenia wybranych odmian ziemniaka do przetwórstwa przemysłowego. Zamieszczone zestawienia dotyczą badań nad odmianami: Adam, Pasja Pomorska i Ślęza, wykonanych w latach 2008-2010, prowadzonych w Stacji Doświadczalnej Uniwersytetu Warmińsko-Mazurskiego w Bałcy-nach. Analizy ekonomicznej dokonano na podstawie zaplanowanych i zrealizowanych zabiegów oraz danych dotyczących rodzaju sprzętu technicznego, nakładów siły roboczej i pociągowej oraz nakładów materiałowych. Na podstawie eksperymentu stwierdzono, że badane odmiany ziemniaka skrobiowego bardzo różnie reagowały na nawożenie dolistne. Najlepiej plonowała odmiana Pasja Pomorska przy nawożeniu doglebowym 280 kg·haˉ¹ NPK (80 N, 80 P, 120 K) i dolistnym stosowaniu Basfoliaru 12-4-6 w ilości 8 dm3·haˉ¹. Biorąc pod uwagę relacje uzyskanych wyników do poniesionych kosztów, odmiana Ślęza charakteryzowała się najlepszym wskaźnikiem opłacalności, który przy każdym wariancie osiągał wartość ponad 2.0. Najkorzystniejszą z punktu widzenia racjonalności gospo-darowania była kombinacja nawożenia na poziomie 420 kg·haˉ¹ NPK (120 N, 144 P, 156 K) oraz z zastosowaniem Basfoliaru 12-4-6 z Soluborem DF w ilości 4 + 1 dm³·haˉ¹. Uzyskano w tym przypadku najwyższy poziom wskaźnika opłacalności.

Statistical data on occupational diseases registered by the Institute of Occupational Medicine in Łódź indicates a renewed increase in the number of pneumoconiosis in Poland in recent years, especially in the section of PKD (Polish Classification of Business Activities) – mining. Simultaneously, in 2018, because of the implementation of Directives of the European Parliament and the Council of the European Union, changes were introduced to Polish legislation in the field of protection of workers against the risk of exposure to carcinogens or mutagens related to the respirable fraction of crystalline silica formed during work. Considering this information, the members of the Department of Safety Engineering of the Silesian University of Technology attempted to assess the dust hazard and the frequency of occurrence of respiratory diseases among the employees of the preparation plant of mine X exposed to the harmful effects of industrial dust produced in the work process. The following methods were used as part of the research: individual dosimetry, infrared spectrometry, directional interview, diagnostic tests, and spirometry. The obtained results made it possible to identify workstations with the highest exposure to the harmful effects of industrial dust and to recognize the impact of this action in the form of pathological changes in the respiratory system in 18.4% of the miners surveyed

Scentless mayweed (T. indorum (L.) Schultz-Bip., Asteraceae), as the dominant weed in winter cereals, on account of producing big biomass makes dangerous concreation for the crops cultivated in the vicinity of GŁOGÓW Copper Foundry (GCF) situated in the Silesia region. The aim of this study was to compare the influence of increasing doses of copper in two temperature ranges on the growth and chlorophyll content among biotypes of scentless mayweed coming from the vicinty of GCF and Wielkopolska province. The experiments were conducted in greenhouse conditions in two temperature ranges: 40/10 °C and 25/5 °C (day/night). The seedlings of T. indorum were grown in pots filled with the soil including different doses of copper (CuSO4 o 5H2O): O, 50, 100, 200,400, 600 and 800 mg Cu/kg of dry soil. The higher doses of copper inhibited the shoot growth and decreased leaf chlorophyll content. The reduction ratę of both parameters was considerably slower in lower temperatures.
Maruna bezwonna to chwast dwuliścienny, dominujący w zbożach ozimych uprawianych na terenie Śląska, gdzie usytuowana jest Huty Miedzi "GŁOGÓW" (HMG). Ze względu na wytwarzanie dużej biomasy stanowi ona silną konkurencję dla rośliny uprawnej. Celem badań było porównanie wpływu wzrastających dawek miedzi w dwóch zakresach temperatur na wzrost i zawartość chlorofilu między biotypami maruny bezwonnej pochodzącymi z rejonu oddziaływania emisji przemysłowych HMG a biotypem pochodzącym z Wielkopolski. Doświadczenia prowadzono w warunkach szklarniowych w przedziale temperatur: 40/10 st.C i 25/5 °C (dzień/noc). Siewki maruny rosły w doniczkach wypełnionych ziemią zawierającą wzrastające dawki miedzi (CuSO4 o 5H2O): O, 50, 100, 200, 400, 600 i 800 mg Cu/kg suchej gleby. Większe dawki miedzi hamowały wzrost pędów oraz zmniejszały zawartość chlorofilu w liściach. Tempo zmniejszania się obu badanych parametrów ulegało znacznemu spowolnieniu w niższych temperaturach.

Objectives: To estimate the incidence of acute leukemia (AL) in El Bierzo (BZ) and to carry out a cross-association analysis in order to suggest some etiological clues. Materials and Methods: We registered all new AL cases diagnosed 2000–2005. Annual standardized incidence rate (SIR) was calculated by the direct method. A cross-association analysis was performed by non-parametric methods and we checked the potential interaction between putative etiological factors by calculating Chi-square-for-trend. Results: SIR was 5.1 cases per 100 000, surpassing the Spanish, European and world average figures and heterogeneous throughout the region. We detected a negative correlation between acute myeloblastic leukemia (AML) SIR in every municipality and both the air distance to the nearest thermoelectric power plant (TPP) (Rho = –0.409; p = 0.01) and to the point of maximum density of the high-power lines (HPL) network (Rho = –0.329; p = 0.04). Accordingly, SIR was higher in the municipalities situated < 7.5 km away from TPP (9.58 vs. 1.72; p = 0.004) or < 10 km away from HPL (3.90 vs. 3.19; p = 0.045). A positive relation between both factors was observed (Chi-square-for-trend = 9.209; p = 0.006). Conclusions: SIR of AL in BZ is higher than the Spanish average and that of most countries in the world. Residing near TPP or HPL confers a higher risk of AML, with synergistic effect between both factors.

Opis:
The research was conducted to evaluate the impact of sulphur compounds on the sex of Colorado potato beetle in the region of sulphur factory in Chmielów near Tarnobrzeg in 1995. The control plantations were situated in the village of Zarębki, about 30km from Chmielów. The object of the study was the average body mass of female and male specimen of the insect after full spring beetle appearance in potato plantations as well as the average body female and male mass after pupation of the larvae of the first generation and emerging from the soil. After six and twelve days of starvation, the average female and male body mass was determined. After twelve days of starvation the incident of cannibalism was noticed among the beetles of the first zone polluted by sulphur compounds.
Prowadzone od szeregu lat badania nad wpływem zanieczyszczonej związkami siarki agrocenozy na stonkę ziemniaczaną wykazały wyraźny negatywny wpływ zmniejszając masę ciała chrząszczy i larw w stadium L₄. Kolejne przeprowadzone w 1995 roku badania dotyczyły stopnia obniżenia średniej masy ciała chrząszcza bez względu na płeć, tak samca jak i samicy tego szkodnika. Otrzymane wyniki wykazały statystycznie istotny spadek średniej masy ciała w 1. Strefie zanieczyszczenia agrocenozy, zarówno samca jak i średniej masy ciała chrząszcza bez względu na płeć w stosunku do masy ciała samicy. Na obiekcie kontrolnym zjawisko to dotyczyło jedynie średniej masy ciała samca. Identyczne badania prowadzono po sześciu i dwunastu dniach głodowania stonki ziemniaczanej. Nienotowanym dotąd zachowaniem się głodujących chrząszczy było zjawisko kanibalizmu, które miało miejsce w obiekcie silnie zanieczyszczonym związkami siarki.

Opis:
Artificial Intelligence algorithms are being increasingly used in industrial applications. Their important function is to support operation of diagnostic systems. This paper presents a new approach to the monitoring of a regenerative heat exchanger in a steam power plant, which is based on a specific use of the Recurrent Neural Network (RNN). The proposed approach was tested using real data. This approach can be easily adapted to similar monitoring applications of other industrial dynamic objects.

Opis:
The results of studies of the mycorrhizal status of plant species spontaneously established on the soda heap located in Jaworzno (Upper Silesia, Poland) are presented. Additionally, the species of arbuscular fungi of the phylum Glomeromycota extracted from field-collected rhizosphere substrate samples of the heap are showed. Arbuscular mycorrhizae were described in 17 plant species. Five Glomus spp. were recognized in the spore populations of arbuscular fungi isolated. The investigation presented in this paper for the first time revealed Centaurea stoebe and Trifolium montanum to be hosts of arbuscular fungi.
