Opis:
Celem podjętych badań było poznanie opinii młodych ludzi na temat zrównoważonego rozwoju. Przedstawienie tych opinii uznano za istotne dla oceny stanu wdrażania zrównoważonego rozwoju – 30 lat po opublikowaniu Raportu Bruntland. Zidentyfikowano również zjawisko „przemocy ekologicznej” oraz opinie na temat kierunków działań przeciwko niej. Zdaniem autorów koncepcja ta powinna zostać uwzględniona, w etycznych podstawach ludzkich zachowań w XXI wieku. Badanie zostały przeprowadzone w 2017 r. wśród studentów Uniwersytetu Rzeszowskiego na Wydziale Biologiczno-Rolniczym oraz Pedagogicznym, a także Wydziale Zarządzania Politechniki Rzeszowskiej. Dla osiągnięcia celu zastosowano metodę badania diagnostycznego z wykorzystaniem kwestionariusza. Otrzymane wyniki wskazują, że edukacja na rzecz zrównoważonego rozwoju nie jest prowadzona jednakowo we wszystkich instytucjach uniwersyteckich. Edukacja ta jest niedoceniana, mimo iż media wyraźnie podkreślają jej znaczenie. Wyniki pracy mogą wskazywać kierunki działań niezbędnych w edukacji dla zrównoważonego rozwoju w XXI wieku. Dla skutecznej edukacji i wdrożenia szeroko pojętego zrównoważonego rozwoju warto przedstawić, przeanalizować i dopracować termin „przemoc ekologiczna”. Niniejsza publikacja stanowi wstępną analizę powyższego problemu. Autorzy mają nadzieję, że przyczyni się to do głębszej analizy możliwego znaczenia terminu „przemoc” również w odniesieniu do zasobów środowiska.
The aim of the study was to learn about young people’s judgements on sustainable development and environmental protection depending on their school profile and education. The presentation of their opinions was considered important for assessing the state of sustainable development 30 years after the publication of the Bruntland Report. The perception of the phenomenon of “ecological violence” and the opinions regarding the directions of actions to combat it were also identified. In the authors’ opinion, this concept should be included in the ethical foundations of human behaviour in the 21st century. The research was conducted in 2017 with students of the Faculties of Biology and Agriculture and of Pedagogy at the University of Rzeszow and students of the Faculty of Management at the Rzeszow University of Technology. In order to achieve the study goals, a diagnostic survey using a questionnaire was used. The results indicate that education in sustainable development is not carried out equally in all university institutions. It is often underestimated, although the media clearly emphasise the need to solve current problems in such a way as to minimise the negative effects of sustainability-related decisions made on the economic, social and ecological dimensions of life. All these dimensions are equally important for the welfare of the human species. The results of the study may indicate the directions of activities necessary in education for the sustainable development in the 21st century. In search of effective educational and implementation activities for broadly defined sustainable development, it is also worth presenting, examining and refining the term “ecological violence”. This article touches on the above issue and is a preliminary consideration in this respect. The authors hope that it will lead them and potential readers to a deeper analysis of the possible meaning of the term “violence” also in relation to environmental resources. The presented research results are regarded as preliminary findings for a deeper analysis of this issue in the future.

Opis:
In the automated world of business, a modern engineer should be characterized by a passion for technology, creativity, innovative capacity, initiative and commitment to scientific and technical progress, ease of adaptation, but also conviction about the mission of technology. Among these, a lack of competence in recognition of, and response to, anthropogenic ecological threats and destruction of biodiversity and ecosystems was noticed. The aim of this article was to draw attention to the problems of educating engineers, to include provision with specialist knowledge and development of necessary competences. The article also refers to the growth of waste production, including packaging waste, presenting an example of the use of activating methods in adult education, deployed in the subject “Waste management” for students of “Renewable energy sources and waste management”, implemented at the University of Rzeszów. Such teaching activity is of great importance in shaping the aforementioned competences.

Opis:
Lumbricidae, as representatives of edaphone, are used in ecological research. Over the years, various attempts to improve the ways of earthworm extraction have been made. One of the pro-environmental methods for extracting these animals from the soil is the method involving the application of electric current (octet). The aim of the study was to compare the efficiency of the earthworm extraction using the mixed method (manual segregation along with the use of 0.5% formalin solution) with the method applying the electroshocking. The species composition of earthworms extracted using both methods was the same (seven species of earthworms belonging to three ecomorphological groups were found). A lower number and biomass of earthworms were found in the permanent grassland and arable land with the help of octet than using the mixed method. Further research is needed to improve the existing methods for Lumbricidae extraction and to implement new ones that would be safe for the edaphon representatives.

Opis:
Lumbricidae play a key role in the soil environment as “the ecosystem engineers”. They participate in all the categories of services provided by ecosystems. In agricultural areas, the conventional intensive farming practices have led to a significant decline in the biological diversity of soils including earthworms. In this study, we attempted to characterize the community structure of earthworms in permanent grassland and arable land of the Didactic & Experimental Station of Rzeszów University in Krasne near Rzeszów. Similar densities of earthworms were observed in the grassland and in the arable land (101.01 ± 18.03 ind. ∙ m-2 and 82.12 ± 18.26 ind. ∙ m-2, respectively) (p > 0.05) as well as a similar biomass of Lumbricidae (77.72 ± 15.30 g ∙ m-2 and 54.34 ± 11.72 g ∙ m-2) (p > 0.05). In the research, 7 species of earthworms were found in the permanent grassland and 6 representatives of Lumbricidae were identified in the arable land. The identified earthworms represented all three main morpho-ecological groups. The density and biomass of epi-endogeic earthworm L. rubellus and the anecic species of L. terrestris were shown to be higher (p < 0.05) in the grassland as compared to the arable land. In order to protect Lumbricidae and to sustain the beneficial role of earthworms in an ecosystem, it is necessary to monitor the negative changes in populations of earthworm species attributed to various farming practices.

Opis:
Earthworms can be used in the vermicomposting process. The success of the process depends on many factors, including the choice of the appropriate earthworm species. Eisenia fetida and Dendrobaena veneta are treated as "compost earthworms". They are characterized by a relatively short life cycle, relatively fast growth rate, efficient reproduction and a similar amount of organic matter processed, compared to species found in the natural environment. However, while analyzing their features in more detail, it can be seen that these two species differ. The aim of this study was to compare the selected features of the Eisenia fetida (Sav.) and Dendrobaena veneta (Rosa) earthworm populations in an annual cycle. The mature specimens of E. fetida or D. veneta were put in groups into plastic boxes with soil. Populations were checked regularly by manual sorting of the medium. The earthworms and cocoons were cleaned, counted and weighed individually. Afterwards, the mature individuals were placed in appropriate containers, while the cocoons were separated from the starting populations. The earthworms were fed ad libidum on kitchen wastes every four weeks. The experiment was carried out under constant laboratory conditions for 52 weeks. The analysis of the studied populations confirmed that the tested species of earthworms differ from each other. After 52 weeks of the experiment, the sum of earthworm biomass was higher for D. veneta compared to E. fetida species (18.568 ± 1.867 g and 7.263 ± 1.786 g; p <0.01, respectively). This relationship was confirmed for the average body weight of earthworms (D. veneta: 0.912 ± 0.046 g; E. fetida 0.480 ± 0.006 g; t = 15.95, p <0.01) and cocoons (D. veneta: 0.032 ± 0.003 g, E. fetida 0.014 ± 0.001 g; t = 9.15, p <0.01).

Opis:
Anesthetic drugs have been tested for years on rats, rabbits, dogs, cats and monkeys, which may raise ethical concerns. Researchers do not always pay attention to the possibility of using techniques of anesthesia, analgesia or euthanasia in relation to invertebrate animals. It has previously been shown that earthworms meet the requirements of laboratory animals, and being a good alternative to the studies on vertebrates, may also be used as the first stage of testing anesthetics. The lethal concentrations of procaine and lidocaine for E. fetida and D. veneta were established using modified filter paper contact test. Using a modified method developed for testing anesthetics, mature earthworms (clitellate) of both species were used to check the effectiveness of lidocaine and procaine in safe immobilizing of earthworms. The reactions of earthworms in contact with anesthetics were different. The possibility of using a higher concentration range of procaine and lidocaine for E. fetida than for D. veneta, as E. fetida demonstrated a greater resistance to the stress caused by the action of chemical substances. The response to this stress varied and depended on the concentration used; however, higher concentrations of anesthetics caused rapid body movements and discharge of the coelomic fluid as well as morphological changes observed after 48 hours. Procaine was not effective in immobilizing earthworms, but lidocaine proved effective in reversibly immobilizing both species. For E. fetida, lidocaine in the concentrations of 1.4 and 1.6 at 95 and 90 min, respectively, resulted in a full immobilization of animals, which then survived following 24h and 48h of recovery. For D. veneta, lidocaine in the concentrations 1.3 and 1.4 during 40 min proved effective and safe to use, as all individuals survived following 24h and 48h of recovery.

Opis:
This paper shows a new combinatorial problem which emerged from studies on an artificial intelligence classification model of a hierarchical classifier. We introduce the notion of proper clustering and show how to count their number in a special case when 3 clusters are allowed. An algorithm that generates all clusterings is given. We also show that the proposed approach can be generalized to any number of clusters, and can be automatized. Finally, we show the relationship between the problem of counting clusterings and the Dedekind problem.

Opis:
Triterpene saponins (saponosides) are found in a variety of higher plants and display a wide range of pharmacological activities, including expectorant, anti-inflamatory, vasoprotective, gastroprotective and antimicrobial properties. Recently, a potential anticancer activity of saponins has been suggested by their cytotoxic, cytostatic, pro-apoptotic and anti-invasive effects. At high concentrations (more than 100 µM) saponins exert cytotoxic and haemolytic effects via permeabilization of the cell membranes. Noteworthy, the inhibition of cancer cell proliferation, the induction of apoptosis and attenuation of cell invasiveness is observed in the presence of low saponin concentrations. Saponins might affect the expression of genes associated with malignancy. These alterations are directly related to the invasive phenotype of cancer cells and depend on "cellular context". It illustrates the relationships between the action of saponins, and the momentary genomic/proteomic status of cancer cells. Here, we discuss the hallmarks of anti-cancer activity of saponins with the particular emphasis on anti-invasive effect of diverse groups of saponins that have been investigated in relation to tumor therapy.

Opis:
Triterpene saponosides are widely distributed plant secondary metabolites characterized by relatively low systemic cytotoxicity and a range of biological activities. These include anti-inflammatory, antimicrobial, vasoprotective and antitumor properties. In particular, the ability of saponins to enhance the cytotoxicity of chemotherapeutic drugs opened perspectives for their application in combined cancer chemotherapy. Here, we used human prostate cancer DU-145 cells as an in vitro model to elucidate the synergy of the interactions between biological activities of an oleanane type 13β,28-epoxy triterpene saponoside (Lclet 4) and mitoxantrone, which is a cytostatic drug commonly used in prostate cancer therapy. No cytotoxic or pro-apoptotic effect of Lclet 4 and mitoxantrone administered at the concentrations between 0.05 and 0.1 µg/ml could be seen. In contrast, cocktails of these agents exerted synergistic pro-apoptotic effects, accompanied by the activation of the caspase 3/7 system. This effect was paralleled by attenuating effects of Lclet 4/mitoxantrone cocktails on the invasive potential, metalloproteinase expression and motility of DU-145 cells. Multifaceted and additive effects of Lclet 4 and mitoxantrone on basic cellular traits crucial for prostate cancer progression indicate that the combined application of both agents at systemically neutral concentrations may provide the basis for new promising strategies of prostate cancer chemotherapy.
