Opis:
W celu poprawy jakości powietrza w miastach oraz zmniejszania emisji CO2 przedsiębiorstwa zachęcane są do budowy układów kogeneracyjnych, czyli skojarzone wytwarzanie ciepła i energii elektrycznej. Budowa układów kogeneracyjnych jest zgodna z ideą zrównoważonego rozwoju, ponieważ skojarzona produkcja energii i ciepła cechuje się bardzo wysoką sprawnością procesu dochodzącą do 90%. Do produkcji tych samych ilości ciepła i energii elektrycznej zużywa się mniej paliwa niż w przypadku produkcji rozdzielonej. Wytwarzanie energii w skojarzeniu pozwala na bardziej efektywne wykorzystanie paliw i zmniejszenie globalnej emisji CO2. Polska, która jest największym producentem węgla w Unii Europejskiej dzięki wykorzystaniu układów kogeneracyjnych wykorzystujących gaz pochodzący ze złóż węgla kamiennego, może dzięki nim zmniejszyć emisję metanu do atmosfery, co ma szczególne znaczenie w przypadku wprowadzenia opłat emisyjnych od metanu. Opracowanie przedstawia wyniki analizy ukierunkowanej na identyfikację ryzyka występującego przy projektach budowy układów kogeneracyjnych małej mocy dla różnego rodzaju przedsiębiorstw. Autor rozdziela istniejące ryzyko ze względu na miejsce pochodzenia ryzyka (źródła zagrożeń) oraz przedstawia przesłanki do zainstalowania takiego układu. Na końcu autor przedstawia analizę SWOT oraz PEST budowy układów kogeneracyjnych małej mocy.
In order to improve air quality in cities and reduce CO2 emissions, companies are encouraged to build cogeneration systems, i.e. the combined production of heat and power. The construction of cogeneration systems is in line with the idea of sustainable development, since the combined production of energy and heat is characterized by a very high process efficiency of up to 90%. Less fuel is used to produce the same amount of heat and electricity than in the case of separate production. Combined heat and power generation allows more efficient use of fuels and a reduction in global CO2 emissions. Poland, which is the largest coal producer in the European Union, thanks to the use of cogeneration systems using gas from coal deposits, can reduce methane emissions into the atmosphere, which is particularly important in the event of the introduction of emission fees on methane. The study presents the results of an analysis aimed at identifying the risks present in the construction projects of low-power cogeneration systems for various types of enterprises. The author separates the existing risks by the place of origin of the risk (sources of risks) and presents the rationale for installing such a system. Finally, the author presents a SWOT and PEST analysis of the construction of low-power cogeneration systems.

Opis:
The paper presents a computer system supporting the identification of vegetable pests during the vegetation period and the way in which it works on the example of red beet. The objective was to develop an expert system to facilitate the identification of pests and suggest an appropriate method of controlling them. Filling the database with the knowledge applying to one narrow area of knowledge turns the expert system framework into an expert system in this area of knowledge. The system consists of the expert system and the database in the form of text files, which contain additional explanations. The user of the expert system - “DSS - pest control” needs to answer the following questions: in the first stage the user selects the diagnosed vegetable, in the second stage, the user selects the symptom or symptoms on the above-ground vegetable part, in the third stage, the user selects the symptom or symptoms on the below-ground vegetable part. The designed decision support system (“DSS - pest control”) may be used by individual vegetable growers. It may also serve as an educational program, e.g. for students who want to find out more about the specific areas of knowledge as well as for scientists and researchers.
Artykuł przedstawia system komputerowy wspomagający identyfikację szkodników warzyw podczas procesu wegetacji, a także sposób jego działania na przykładzie buraka czerwonego. Celem było opracowanie systemu ekspertowego ułatwiającego identyfikację szkodników oraz zaproponowanie odpowiedniej metody ich zwalczania. Wypełnienie bazy wiedzy informacjami odnoszącymi się do wąskiego obszaru wiedzy zamienia system ekspertowy w system w danej dziedzinie wiedzy. System składa się z systemu ekspertowego oraz bazy danych w postaci plików tekstowych, które zawierają dodatkowe wyjaśnienia. Użytkownik systemu ekspertowego - "DSS - zwalczanie szkodników" musi odpowiedzieć na następujące pytania: w pierwszym etapie użytkownik wybiera diagnozowane warzywo, w drugim etapie użytkownik wybiera objaw lub objawy na nadziemnej części warzywa, w trzecim etapie użytkownik wybiera objaw lub objawy na podziemnej części warzywa. Zaprojektowany system wspomagania decyzji ("DSS - zwalczanie szkodników") może być stosowany przez indywidualnych plantatorów warzyw. Może również służyć jako program edukacyjny, np. dla studentów, którzy chcą pogłębić swoją wiedzę, może być także pomocny dla naukowców i badaczy.

With the advent of the pandemic and the outbreak of individuality in inter-state politics, semiconductors, products that have become widely used by high-tech companies, have led to an increase in worldwide demand. But growing nationalism has led nations not to cooperate on the successful joint and equitable growth of these innovative technologies. This research analyses through a PEST analysis the political, economic, social and technological consequence of these choices for the largest semiconductor company, TSMC. The results show how, to date, the international chessboard poses four choices facing TSMC’s future, each based on how nations will approach future collaborative choices.

Opis:
To improve plant resistance to pests, we analysed the impact of various agronomic practices on the number and species diversity of pests in the crops of spring wheat varieties of foreign and Kazakhstan breeding in North-Eastern Kazakhstan. The intensive development of agriculture, resulting in the new technological flow processes of wheat growing, the sowing of foreign varieties not previously cultivated under local conditions, and climate change contribute to the formation of new food chains in agrocenoses. These new food chains require the monitoring of plant-feeding species with the help of ecological approaches and techniques. Efficient protection of crops with plant feeders requires constant updating on the phytosanitary in agrocenoses. Information on phytosanitary monitoring previously carried out in the region is not available, so it became necessary to collect data and analyse the number and species composition of wheat pests, considering new foreign varieties and cultivation technology practices. The research was carried out in 2021 in typical agricultural organisations of the North-Eastern regions of Kazakhstan with different preceding crops. The vegetation period was characterised by high atmospheric temperatures and a lack of moisture in the soil in spring and summer, contributing to decreasing of plant turgor and damage resistance. Early sowing of the ‘Triso’ wheat variety was affected by high temperatures and lack of soil moisture in the initial stage of development, which delayed its growth and made it more susceptible to pest damage. The other varieties were sown in optimal dates recommended by regional scientific institutions.

Opis:
Global warming and climate change are some of the most widely discussed topics in today's society, and they are of considerable importance to agriculture globally. Climate change directly affects agricultural production. On the other hand, the agricultural sector is inherently sensitive to climate conditions, and this has made the agricultural sector one of the most vulnerable sectors to the effects of global climate change. Rising CO2 levels in the atmosphere, increased temperature, and altering precipitation patterns all substantially influence agricultural insect pests and agricultural productivity. Climate change has a number of implications for insect pests. They can lead to a decreased biological control effectiveness, particularly natural enemies, increased incidence of insect-transmitted plant diseases, increased risk of migratory pest invasion, altered interspecific interaction, altered synchrony between plants and pests, increase in the number of generations, increased overwintering survival, and increase in geographic distribution. As a consequence, agricultural economic losses are a real possibility, as is a threat to human food and nutrition security. Global warming will necessitate sustainable management techniques to cope with the altering state of pests, as it is a primary driver of pest population dynamics. Future studies on the impacts of climate change on agricultural insect pests might be prioritized in several ways. Enhanced integrated pest control strategies, the use of modelling prediction tools, and climate and pest population monitoring are only a few examples.

Opis:
Dynamika zmian dotyczących aspektów politycznych, ekonomicznych, społecznych, technologicznych wpływa na kształtowanie się modeli biznesowych we wszystkich sektorach gospodarki. I właśnie metodę PEST wykorzystano do opisania globalnych uwarunkowań funkcjonowania systemu energetycznego. Obecnie zmiany te w opisywanym sektorze następują w procesie wykładniczym. Przyjęto w artykule, że model biznesowy jest wynikiem procesu wyłaniającego się z ewolucji otoczenia, które oddziałuje na obraz sektora. W związku z tym celem artykułu jest przedstawienie globalnych uwarunkowań wpływających na kształt nowego modelu biznesowego opartego na metodzie łańcucha wartości M. Portera. Istotą tak zorganizowanego procesu jest tworzenie wartości ekonomiczno-społecznej. Staje się to dominującym podejściem w tworzeniu nowego modelu biznesowego systemu energetycznego w całym świecie.
The dynamics of changes in political, economic, social and technological aspects affect the formation of business models in all sectors of the economy and it was the PEST method that was used to describe the global determinants of energy system performance. Currently, these changes in the described sector are occurring in an exponential process. It is assumed that the business model is the result of a process that emerges from the environment evolution affecting the image of the sector. Therefore, the purpose of the article is to present the global determinants affecting the shape of the new business model presented on the basis of M. Porter’s value chain method. The essence of such an organized process is the creation of economic and social value. This is becoming the dominant approach in the creation of a new business model of the energy system around the world.

Niniejszy artykuł analizuje praktyki dyskursywne kształtujące tożsamość zawodową deratyzatorów (tępicieli gryzoni). Wywiady z pracownikami tej branży ukazują retorykę wytężonej pracy nad tożsamością. Stawiam tezę, że budowanie owej tożsamości lokuje się na dwóch poziomach. Pierwszy z nich (społeczny) wyznacza tożsamość budowaną w kontrze do percypowanego negatywnego odbioru społecznego. Drugi poziom (indywidualny) to praca „do wewnątrz”, obrazująca mierzenie się z etycznymi wyzwaniami związanymi z wykonywanym zawodem. Na podstawie przeprowadzonych wywiadów rozpoznaję cztery strategie racjonalizacji tępienia zwierząt. Owe dwa poziomy pracy nad tożsamością posiadają wspólny rdzeń, którym jest przekonanie o społecznej użyteczności pracy w deratyzacji.
This article analyzes the discursive practices that shape rat exterminators’ professional identity. Interviews with pest control professionals (PCPs) reveal the rhetorics of hard work on their identity. My main thesis is that the shaping of this identity is performed on two levels. The first one (social) is about identity shaped in opposition to the perceived negative social reception of this profession. The second one (personal)is about internal work based on struggling with the ethical challenges connected with the professional duties. Based on the conducted interviews, I have recognized four strategies of the rationalization of exterminating animals. The above-mentioned two levels of identity work have the common, namely the belief in the social usefulness of working in pest control.

In this short communication describing experiments carried out on the larvae of two insects, Unaspis euonymi Comstock (feeding on Euonymus japonicus Thunb.) and Dynaspidiotus britannicus Newstead (feeding on Laurus nobilis L.), we evaluate for the first time the efficiency of using DNA insecticides in the control of sap-sucking insects, including armored scale insects. Over a period of 10 days, high insect mortality was detected in both U. euonymi and D. britannicus, accompanied by a significant decrease in the concentration of target RNAs. At the same time, no visible changes were observed when the leaves of the host plants were subjected to treatment with DNA insecticides for one month. The results show the high efficiency of DNA insecticides used against hemipteran insect pests. It is noteworthy that the high efficiency of DNA insecticides and their low cost in comparison with RNA preparations provides a safe and extremely promising potential vehicle for the control of sap-sucking insects.

Opis:
The article is focused on microbiological and silvicultural properties of bacterial wetwood of silver birch (Betula pendula), also known as European white birch. During the active phase of the disease, bacterial wetwood (i.e. bacterial dropsy, vascular parenchymatous bacteriosis or flux slime) is characterised by crust and periderm bloating, necrotic wet stains and abundance of exudate. The disease is more likely to occur in older (r = 0.56, p < 0.01) and less-dense (r = −0.29, p < 0.01) stands. The statistical model showed that the chance of bacterial wetwood increases with birch age by 0.36% per year. The stands with birch proportion of over 70% demonstrated 15.3% lower infection rate compared to the stands with lower birch presence. The stands with lower stocking demonstrated a higher proportion of infected tree distribution by 7.5% compared to the stands with higher birch representation. The most vulnerable were larger, older B. pendula trees with longitudinally fissured bark that grow on poorer soils and experience frequent water stress. Birch associations with Pteridium aquilinum and Vaccinium myrtillus were more susceptible to infection (31.6% and 44.3%, respectively), whereas associations with Brachypodium sylvaticum, Sphagnum palustre and Calluna vulgaris were at lower risk. Strong ecological and trophic association of bacterial wetwood was present between silver birch and Tremex spp., particularly Tremex fuscicornis. Mycobiota was represented by Rhizopus microsporus, Mucor mucedo, Penicillium aurantiogriseum, Penicillium purpurogenum and Acremonium strictum. Enterobacter, Xanthomonas, Pantoea and Bacillus spp. associated with bacterial wetwood of silver birch were isolated. Enterobacter nimipressuralis was found to be the primary causative agent through means of artificial infection, while other bacteria were found to be either weak pathogens or concomitant. E. nimipressuralis formed the largest number of colony-forming units (CFU) for bark and cambium (164 and 127 CFU, respectively) and was also found in a small amount as a vital obligate in the automicrobiota in healthy birch trees.

Opis:
Soybean [Glycine max (L.)], one of the most important crops in Argentina, is commonly infected by Colletotrichum truncatum, the causal agent of anthracnose. Tagetes filifolia essential oil (EO) is presented as a natural approach to minimize the dose of chemical fungicides applied to the crop. The fungus Trichoderma harzianum is used as a biocontrol agent because of its ability to produce secondary metabolites that destroy cell walls of phytopathogenic fungi. However, its performance can be affected when it is exposed to chemical fungicides. The objective of this work was to evaluate the antifungal activity of T. filifolia EO both individually and combined with chemical fungicides against C. truncatum, and its effect on T. harzianum. Fungi were isolated from soybean crops. The following pesticides were assessed: carbendazim (F1), difenoconazole (F2) and trifloxystrobin + cyproconazole (F3). The EO was obtained from native plants and its chemical composition was analyzed by gas chromatography–mass spectrometry (GC–MS). The minimum fungicide concentration (MFC) was determined for each compound. Fungicides were combined with the EO to look for combinations that allowed a reduction of pesticide doses. Among fungicides, F1 showed the strongest antifungal activity against C. truncatum (MFC = 0.25 µl ⋅ l–1) and T. harzianum (MFC = 1.5 µl ⋅ l–1). The sensitivity of both fungi to the EO was lower than to fungicides. The EO presented MFCs of 6,000 and 9,000 µl ⋅ l–1 against C. truncatum and T. harzianum. The EO and F1 affected the growth of T. harzianum at concentrations that controlled C. truncatum (31 and 10%). Eight combinations of fungicides and the EO allowed fungicide concentration reductions of up to 80%, although the growth of the biocontrol strain was also affected. The results demonstrated that T. filifolia EO can be used to control anthracnose and reduce doses of chemical fungicides applied to soybean crops. Its effect on T. harzianum should be considered in the design of integrated pest management strategies.

Opis:
The Indian meal moth, Plodia interpunctella (Lepidoptera: Pyralidae) is one of the most important stored product pests. Fumigation plays a significant role in the management of insect pests in stored-products. However, the use of fumigants is problematic because of their effects on the environment and high costs. Entomopathogenic organisms are environmentally friendly control agents and suppress pest populations under natural conditions. In this study, distribution and occurrence of a microsporidian pathogen, Vairimorpha plodiae (Opisthokonta: Microspora) in the populations of P. interpunctella from 12 localities representing Turkey between 2019 and 2020 are presented for the first time by confirming its effectiveness on natural populations. The presence of the microsporidian pathogen was found in 11 of 12 (91.7%) populations. In total, 863 of 3,044 samples were infected by the pathogen. Infection mean was 28.4% for all populations. Our results showed that V. plodiae infection reached to a considerably high prevalence (88.77%) in P. interpunctella populations and varied from 5.1 to 88.7% between the populations. In addition, microsporidia infections have been identified throughout Turkey. We found that V. plodiae can infect all life stages of P. interpunctella. Totally, 623 (28.5%) of 2187 larvae, 14 (37.8%) of 37 pupae, 226 (27%) of 820 adults were found to be infected by the pathogen. There were considerable differences between the dead and living larvae. The microsporidian infection was found in 26 (11.6%) of 225 living larvae, whereas it was found in 595 (30.5%) of 1,952 dead larvae. These results confirm that the microsporidia pathogen has a high spreading potential in P. interpunctella populations and can be a natural biological suppression factor on pest populations.

Opis:
The species Halyomorpha halys (Stål), which is endemic in East Asia, was first detected in North America in 1996 and was probably introduced into Europe in 2008. The species is polyphagous. It consumes over 170 host plant species and significantly impacts crop pro- duction. In Greece the first recording of its presence was in 2014, when it was reported as a nuisance in houses in the region of Athens. The present study describes the systematic spread and damage of this invasive pest, including the first recorded identification in peach and olive cultivations in the prefecture of Imathia in central Macedonia, Greece. Sampling was carried out in representative peach and olive farms during July and August, 2018 and 2019 in which significant levels of fruit damage were recorded, especially during 2018. The population of the species was recorded throughout the winter seasons of 2018 and 2019 in which overwintering adults were systematically recorded in shelters and other construc- tions near fruit orchards. Given the dynamics of the species and its destructive impact on a wide range of host species, H. halys is expected to be a major pest. Additionally, considering that the prefecture of Imathia is the most important peach growing area of Greece, further studies of the presence and population dynamics of this species along with the establishment of particular management actions to control the population is impera- tive for the future protection of horticultural production in Greece.

Opis:
Tuberolachnus salignus is a cosmopolitan aphid that predominantly feeds on the willow. It can be an economically im-portant pest of this plant. The aim of the study was to present the thematic scope of the literature on this species in Poland and in the world. The typical issues related to aphid biology (life cycle, nutrition, distribution) and its potential harmfulness are consid-ered. Additionally, aphid genetics, dyes, natural enemies, indirect influence on the soil environment as well as the use of this insect species in research on plant physiology are taken into account. It was found that in recent years, the studies on giant willow aphid have been mainly motivated by the potential utilisation of the results in the protection of willow against this aphid. Despite a wide range of topics, the publications collected in the SCOPUS and Web of Science databases are not sufficient sources of in-formation about this species. The available data must be supple-mented and updated using modern research methods. The experi-ments and observations should consider the direct and indirect relationships of T. salignus with other organisms and the environment.
