    Designing an ESP course in an academic setting is a multidimensional challenge. To meet it, we should address the needs and interests of our students, which in most cases means incorporating subject-specific content (specialized vocabulary, typical genres, authentic materials, discourse communities practices) into a language course. This on the practitioners' part involves tackling their lack of disciplinary expertise, which might be very diffi cult for various factors. One of them might be diffi culty in gaining expertise due to a wider curriculum and institutional policies (like teaching many ESPs at the same time). Another might be finding the right balance between discipline-based knowledge and pure language on such a course. It seems that the adequate language teaching expertise which the practitioners should possess in order to help students start using the language as a communication tool for their academic and occupational purposes, can be achieved through a careful choice of the syllabus type to be adopted, the academic skills and genres to be practised, the specialized topics for the language to be presented and reliable sources of materials to raise motivation and serve as an example. This paper describes taking the aforementioned elements into account when designing specialized English language courses for BSc and MSc students of Biology, Geography and Physics, at the Faculty of Science, Masaryk University in Brno, Czech Republic. It analyses which language course elements can be shared across the mentioned sub-disciplines of EST, and where their syllabi start to diverge

    Structural phase transitions and their influence on Cu+ mobility in superionic ferroelastic Cu6PS5I single crystals

    Full text link
    The structural origin of Cu+ ions conductivity in Cu6PS5I single crystals is described in terms of structural phase transitions studied by X-ray diffraction, polarizing microscope and calorimetric measurements. Below the phase transition at Tc=(144-169) K Cu6PS5I belongs to monoclinic, ferroelastic phase, space group Cc. Above Tc crystal changes the symmetry to cubic superstructure, space group F-43c (a=19.528); finally at 274K disordering of the Cu+ ions increases the symmetry to F-43m, (a=9.794). The phase transition at 274K coincides well with a strong anomaly in electrical conductivity observed in the Arrhenius plot. Diffusion paths for Cu+ ions are evidenced by means of the atomic displacement factors and split model. Influence of the copper stechiometry on the Tc is also discussed.Comment: conference pape

    Yeasts can have additional genetic information in the form of cytoplasmic linear dsDNA molecules called virus-like elements (VLEs). Some of them encode killer toxins. The aim of this work was to investigate the prevalence of such elements in D. hansenii killer yeast deposited in culture collections as well as in strains freshly isolated from blue cheeses. Possible benefits to the host from harboring such VLEs were analyzed. VLEs occurred frequently among fresh D. hansenii isolates (15/60 strains), as opposed to strains obtained from culture collections (0/75 strains). Eight new different systems were identified: four composed of two elements and four of three elements. Full sequences of three new VLE systems obtained by NGS revealed extremely high conservation among the largest molecules in these systems except for one ORF, probably encoding a protein resembling immunity determinant to killer toxins of VLE origin in other yeast species. ORFs that could be potentially involved in killer activity due to similarity to genes encoding proteins with domains of chitin-binding/digesting and deoxyribonuclease NucA/NucB activity, could be distinguished in smaller molecules. However, the discovered VLEs were not involved in the biocontrol of Yarrowia lipolytica and Penicillium roqueforti present in blue cheeses

    Praca dotyczy analizy portfelowej, w kt贸rej ryzyko jest mierzone warto艣ci膮 zagro偶on膮 (VaR), a wektor st贸p zwrotu walor贸w ryzykownych ma rozk艂ad normalny. Przy za艂o偶eniu, 偶e kr贸tka sprzeda偶 walor贸w ryzykownych jest dopuszczalna zbadano przypadki, gdy nie ma waloru pozbawionego ryzyka i gdy taki walor istnieje. Przeanalizowano model Blacka i zmodyfikowany model Tobina, stosuj膮c VaR jako miar臋 ryzyka. Om贸wiono podobie艅stwa i r贸偶nice mi臋dzy modelami stosuj膮cymi odchylenie standardowe jako miar臋 ryzyka, a tymi stosuj膮cymi VaR. Zwr贸cono uwag臋 na fakt, 偶e od poziomu ufno艣ci przyjmowanego do wyznaczania VaR zale偶y istnienie portfeli efektywnych. Wyniki uzyskane dla modelu z walorem bezryzykownym i miar膮 ryzyka VaR nie wyst臋puj膮 w literaturze.The article concerns portfolio analysis where risk is measured by value at risk (VaR) assuming that the returns are normally distributed and short-selling of risky securities has no limitations. Two models have been analysed: one with the assumption that no risk-free security exists in the economy, another assuming just one risk-free security. An analysis of Black Model and Modified Tobin Model has been carried out using VaR as the measure of risk. Models with VaR as a measure of risk and standard deviation as measure of risk have been compared. It is shown that, depending on the confidence level used to calculate VaR, an efficient portfolio might not exist. The results for the model with one risk-free asset and VaR as a measure of risk have not been published before and are the original contribution of this paper

    Chlorofile charakteryzuj膮 si臋 znacz膮c膮 absorpcj膮 艣wiat艂a w zakresie widzialnym i bliskiej podczerwieni oraz wysok膮 wydajno艣ci膮 stan贸w trypletowych. Dlatego stanowi膮 potencjalne fotosensybilizatory w terapii fotodynamicznej. Celem pracy by艂a synteza i poszukiwanie kompleks贸w przej艣ciowych pochodnych chlorofili, w kt贸rych centralny jon magnezu jest zast膮piony przez jon palladu (II) lub platyny (II). Zwi膮zki kompleksowe wymienionych metali s膮 u偶ywane w terapii antynowotworowej, dlatego spodziewane jest dodatkowe cytotoksyczne dzia艂anie ich kompleks贸w z chlorofilami. Ponadto, insercja jonu metalu o wysokiej liczbie atomowej sprawia, i偶 barwnik zyskuje korzystne w艂a艣ciwo艣ci takie jak lepsze dopasowanie energii wzbudzenia do okna terapeutycznego, czy zwi臋kszon膮 wydajno艣膰 generowania tlenu singletowego. G艂贸wnym celem by艂a optymalizacja metody otrzymywania platynowej pochodnej chlorofilu a. Syntez臋 prowadzono u偶ywaj膮c zmodyfikowanej metody octanowej przy u偶yciu tetrachloroplatyny (II) sodu. Znaleziono optymalne warunki prowadzenia syntezy i rozdzia艂u produkt贸w. Produkt charakteryzuje si臋 zwi臋kszon膮 rozpuszczalno艣ci膮 w wodzie, nisk膮 intensywno艣ci膮 emisji fluorescencji oraz wysok膮 absorpcj膮 艣wiat艂a w zakresie okna terapeutycznego, co umo偶liwia jego zastosowanie w terapii fotodynamicznej. Kolejnym celem by艂o poszukiwanie kompleks贸w przej艣ciowych palladowych pochodnych chlorofili. Zaobserwowano widma absorpcji dw贸ch kompleks贸w przej艣ciowych powstaj膮cych podczas syntezy palladowej pochodnej chlorofilu a z u偶yciem chlorku palladu (II) w metanolu.Chlorophylls exhibit significant absorption in the visible and near-infrared region and high quantum yield of triplet state. Therefore, they are promising photosensitizers applicable in photodynamic therapy. The purpose of the project was the synthesis and search for intermediate complexes of chlorophylls in which the central magnesium ion is substituted for palladium (II) or platinum (II) ion. Complexes of mentioned metals are used in cancer therapy, therefore an additional cytotoxic activity for the their complexes with chlorophylls is expected. Moreover, as a result of insertion of the metal ion with high atomic number pigments gain new interesting properties such as better suit to therapeutic window and enhanced quantum yield of single oxygen generation. The main aim was to develop synthetic and purification techniques for obtaining platinum derivative of chlorophyll a. The synthesis of this pigment was conducted using modified acetate method with the use of sodium tetrachloroplatinate (II). Optimal conditions of conducting the reaction and product purification was found. Obtained product exhibit enhanced water solubility, decreased fluorescence emission and enhanced light absorption in therapeutic window, which is why it is potent photosensitizer for photodynamic therapy. The next aim was the search for intermediate complexes of palladium (II) derivatives of chlorophylls. Absorption spectra of two intermediate complexes of palladium derivative of chlorophyll a were observed during its synthesis with the use of palladium (II) chloride in methanol
