    Opis:
    Evolutionary processes lie at the base of the entire observable biodiversity, both at present and in the geological past (i.e., in the fossil record). For this reason, the teaching of evolution should receive more recognition than it currently has (e.g., in Poland) and become accurately applied from the early formal education stages onwards. To test the possibility of effective teaching of evolution to primary school pupils, workshops using non-standard learning methods (‘purposefully-framed play’) were organised during childrens’ university (UNIKIDS) courses of one-hour sessions for 33 groups, comprising several to 20 participants, aged 7 to 12. The final task for all participants was to predict future evolutionary processes by creating new species adapted to given environmental factors. Pupils effectively completed this task, but a few misconceptions also become clear. These workshop scenarios suggest that evolution can be taught effectively at least in extracurricular settings to primary school pupils, but for a detailed insight, a quantitative analysis and application of such scenarios in school programmes should be tested in future.

    Opis:
    Science classes in public schools are usually strictly linked to several subjects and taught by reference to the reading-listening model. Non-formal educational institutions and events such as ‘children universities’ and science fairs (and to some degree also some private schools) implement elements of interdisciplinary teaching of science and learning through experiments and the use of scientific methods. Workshops conducted within non-formal educational structures prove that only is this method engaging and understandable to primary school pupils, it also is possibly much more effective than the traditional learning style for coding information and explaining common misconceptions in teaching evolution, palaeontology and biodiversity. The example of a scenario for science classes presented here (the so-called ‘aquatic problem’, i.e., adaptations of primarily terrestrial animals – amniotes – to the aquatic environment) uses simple props, such as everyday items, to address the problems that teachers in public school face. Thus, it can be implemented independently of school budgets and availability of school equipment.

    Opis:
    The incomplete, articulated, right pes of an aetosaur, extracted from the lower bone-bearing horizon of the Krasiejów Late Triassic site, is larger than any other, known from among the Aetosauria. Its individual bones resemble those of at least three genera: Desmatosuchus (astragalus), Typothorax (ungual phalanges), and Stagonolepis (metatarsals). This underscores the highly speculative nature of the taxonomical classification of isolated postcranial bones and makes it impossible to assign the limb to any particular genus. The phalangeal formula is 2-3-4-5-?; for the fifth finger: 2/3/4 is possible. The anatomy of the pes indicates adaptation for digging.

    Upper Triassic
    Opis:
    In recent years, the Upper Triassic deposits at Krasiejów (south-west Poland) have yielded several tetrapod taxa, both aquatic and terrestrial. Stagonolepis olenkae is one of the terrestrial vertebrates recovered there; a quadrupedal, armoured aetosaur, which belonged to the crocodile-line archosaurs with a characteristic shovel-shaped snout. Several previous studies (osteological, histological and taphonomic) have attempted to understand the mode of life, growth pattern and possible dimorphism of this species and on this basis, to interpret palaeoecological, palaeoclimatic and stratigraphical implications. So far, the pelvic girdle of S. olenkae from Krasiejów remained undescribed. Here, the authors record stagonolepid ilia and pubes and a single ischium from collections housed at the University of Opole, and compare these with the pelvic girdles of other aetosaurian taxa. These well-preserved bones have a typical aetosaurian general outline, but also show some peculiar features. For instance, the preacetabular blade of the ilium is short and flattened and does not exceed the pubic peduncle; several small foramina occur dorsally of the supracetabular crest; the number of pubic foramina is two and the pubic symphysis is less than half the length of the pubis. The material is similar to previously known Stagonolepis robertsoni from the Elgin area, except for the length of the symphysis. The bones presented here differ between each other in thickness, morphology of the preacetabular blade or attachment of sacral ribs, which may be connected with sexual dimorphism. The pelvic girdle of most aetosaurs is not well known. This is unfortunate, because it is an important element in the study of the evolution of the pelvic girdle and in phylogenetic analyses. Thus, the ilia, pubes and ischium of the present study are valuable examples that may contribute to the discussion of the ontogeny and sexual dimorphism in Stagonolepis, as well as to our general knowledge of the Aetosauria.

    Opis:
    Middle Triassic (Muschelkalk) limestones and dolostones of southern Poland contain vertebrate remains, which can be used for palaeoecological and palaeogeographical analyses. The results presented concern vertebrate remains uncovered at four localities in Upper Silesia and one on Opole Silesia, a region representing the south-eastern margin of the Germanic Basin in Middle Triassic times. The most abundant remains in this assemblage are fish remains, comprising mostly actinopterygian teeth and scales. Chondrichthyan and sauropsid remains are less common. Reptilian finds include vertebrae, teeth and fragments of long bones, belonging to aquatic or semi-aquatic reptiles, such as nothosaurids, pachypleusorosaurids, and ichthyosaurids. Also, coprolites of possibly durophagous and predacious reptiles occur. In the stratigraphic column of Mikołów, actinopterygian remains are the most numerous and no distinct changes of the taxonomic composition occur. Although this assemblage differs from those described at other localities (Ząbkowice with numerous chondrichthyans, Żyglin, and Płaza with common sauropsid fossils), sampling bias has to be considered.

    Opis:
    Fossil vertebrate remains from the Keuper unit in the vicinity of the village of Krasiejów have been analyzed for almost two decades. However, the main goal of these works was focused mainly on large vertebrates. Here the authors present the first description of microvertebrate fossils from that site. The collection of around 5,000 specimens is mainly comprised of teeth and scales. The most numerous remains belong to osteichthyans: dipnoans (Ptychoceratodus and cf. Arganodus), palaeoniscids, semionotids, redfieldiids and chondrichthyans, such as Lonchidion sp., which is the first indisputable record of that genus in the Upper Triassic of Poland and the first shark at the Krasiejów locality. Tetrapod fossils consist of temnospondyl amphibians, rhynchocephalian lepidosauromorphs and archosauromorphs. Among them, temnospondyl amphibian remains are the most numerous and are represented mostly by Metoposaurus. However, on the basis of diversity in tooth morphotypes, the occurrence of other taxa cannot be excluded. Rhynchocephalians are composed of 7 fragmentary jaw morphotypes with dentition, which could indicate high taxonomic diversity (cf. Planocephalosaurus, cf. Diphydontosaurus and cf. Clevosaurus). The most varied fossil group was assigned to the archosauromorphs. The authors can distinguish at least 19 teeth morphotypes, which show similarities to the dentition of: protorosaurians (cf. Tanystropheidae), pseudosuchians (cf. Protecovasaurus, cf. Revueltosaurus), early crocodylomorphs and basal sauropodomorph dinosaurs. The first occurrence of a theropod dinosaur and cynodonts at the Krasiejów locality is also recorded. However, their remains are very rare. These new records show a high taxonomic diversity at the Krasiejów locality that contributes to our deeper understanding of Late Triassic ecosystem of Poland.

    Opis:
    In most production plants, waste heat is usually discharged into the environment, contributing to a reduction in the energy efficiency of industrial processes. This is often due to the low thermal parameters of the carriers in which this energy is contained, such as oils, water, exhaust gases or other post-process gases, which means that their use for electricity production in a conventional Rankine cycle may prove to be economically unprofitable. One of the technologies enabling the use of lowand medium-temperature waste heat carriers is the organic Rankine cycle (ORC) technology. The paper present results of calculations performed to evaluate potential electricity production in ORC using waste heat from a natural gas-fired glass melting furnace. The analysis was carried out assuming the use of a single-stage axial turbine, whose efficiency was estimated using correlations available in the literature. The calculations were carried out for three working fluids, namely hexamethyldisiloxane, dimethyl carbonate, and toluene for two scenarios, i.e. ORC system dedicated only to electricity production and ORC system working in cogeneration mode, where heat is obtain from cooling the condenser. In each of the considered cases, the ORC system achieves the net power output exceeding 300 kW (309 kW for megawatts in the cogenerative mode to 367 kW for toluene in the non-cogenerative mode), with an estimated turbine efficiency above 80%, in range of 80,75 to 83,78%. The efficiency of the ORC system, depending on the used working fluid and the adopted scenario, is in the range from 14.85 to 16.68%, achieving higher efficiency for the non-cogenerative work scenario.

    Opis:
    Social inclusion of people with intellectual disabilities is determined by the opportunity to acquire appropriate social and civic competences. These competences are an essential condition for active participation in social life by each individual. This article discusses the issue of civic competence developed during formal and informal training. The considerations are based on conclusions from the research of social and civic competences conducted in a special vocational school for students with mild intellectual disabilities. The aim  of the research was to check the effectiveness of civic competences training. The research population was made up of students taking part in the one-semester project "Young Citizen" and students from the control group not covered by the project.  In the exploration, the researchers used Questionnaires of Social and Professional Competences for people with  mental disabilities and their carers and also author's interview questionnaire on selected civic competences. The research results show that all respondents have a similar range of basic knowledge about society. Students taking part in the training have broader competences in the fild of civic issues.
    Inkluzja społeczna osób z niepełnosprawnością intelektualną jest zdeterminowana możliwością nabywania przez nich odpowiednich kompetencji społecznych i obywatelskich. Kompetencje te są istotnym warunkiem aktywnego udziału jednostki w życiu społecznym. Niniejszy artykuł porusza problematykę kompetencji obywatelskich, rozwijanych podczas formalnego i nieformalnego treningu. Rozważania opierają się na wnioskach z badań kompetencji społecznych i obywatelskich przeprowadzonych w specjalnej szkole zawodowej dla uczniów z niepełnosprawnością intelektualną w stopniu lekkim. Celem badań było sprawdzenie efektywności treningu kompetencji obywatelskich w wybranej placówce. Populację badawczą stanowili uczniowie biorący udział w trwającym jeden semestr projekcie Młody Obywatel oraz uczniowie z grupy kontrolnej nieobjętej projektem. W eksploracji wykorzystano Kwestionariusz kompetencji społeczno-zawodowych KKSZ dla ONU i ich opiekunów oraz autorski kwestionariusz wywiadu dotyczący wybranych kompetencji obywatelskich. Wyniki badań pokazują, że wszyscy respondenci posiadają podobny zakres podstawowej wiedzy o społeczeństwie. Pogłębione kompetencje dotyczące problematyki obywatelskiej mają uczniowie biorący udział w treningu.

    Opis:
    The Warta River valley was greatly influenced by the ice sheet of the Last Glacial Maximum (LGM). A small peatland located in the Warta drainage system is here used as a palaeoarchive of climatic and habitat changes during the Late Glacial (Weichselian). The Ługi sediment profile was investigated using multi-proxy (pollen, Chironomidae, Cladocera and geochemistry) analyses that recorded changes in a fluviogenic sedimentary depression. After the Poznań Phase (LGM), Ługi functioned as an oxbow lake that was cut off from the active river channel as a result of fluvial erosion. Since that time, the Warta River has flowed only along the section now occupied by the Jeziorsko Reservoir. Sedimentation of lacustrine deposits started at the beginning of the Late Glacial. Summer temperature reconstructions indicate cool Oldest and Younger Dryas, but no clear cooling in the Older Dryas. During the Younger Dryas the palaeolake was completely occupied by a peatland (fen), which periodically dried out during the Holocene. Investigation of this site has tracked the reaction of the habitat to climatic, hydrological and geomorphological changes throughout the Late Weichselian.
