One of the characteristics of the Late Band Pottery (Band Keramik) culture (Lengyel culture – Brześć Kujawski group) on the Polish Lowlands are settlements of the Brześć Kujawski type. This name also describes extensive (3–6 ha) systems repeated over several hundreds of years as residential complexes composed of numerous so–called longhouses as well as other accompanying earthen economic and funereal structures. On the Polish Lowland, these have hitherto been found exclusively on the lands of Kujavia, where they occurred in the period 4500–4000 B.C. This paper aims to initially present two new settlements, the first to be discovered outside of Kujavia: Racot (Wielkopolska) and Zelgno (Chełmno Land). and Jedním z charakteristických rysů pozdní fáze lengyelské kultury (skupina Brześć Kujawski) v Polské nížině je výskyt osad typu Brześć Kujawski. Jedná se o rozlehlé (3–6 ha), v průběhu několika set let opakovaně obnovované areály obytné zástavby, složené z početných tzv. dlouhých domů a dalších, hospodářských či hrobových objektů. Z Polské nížiny byly doposud známy výlučně z Kujav, kde vznikaly v době 4500–4000 př. Kr. Článek přináší poznatky o dvou nových osadách odkrytých prvně mimo oblast Kujav – v Racotu (Velkopolsko) a Zelgnu (Chelmiňsko).
This report describes 7 new species of Drosophila found in the Eastern Arc mountains and on Mount Kilimanjaro in Tanzania: D. baucipyga, D. gata, D. kilimanjarica, D. neogata, D. paragata, D. pilocornuta and D. usambarensis spp.n. Two new species complexes, the megapyga species complex (Sophophora subgenus, melanogaster group, montium subgroup) and the gata species complex (Drosophila subgenus) are introduced. Only one species, D. baucipyga of the montium subgroup, has a geographical range matching the whole Eastern Arc, from the Usambara Mts. in the north-east of Tanzania to Mt. Uzungwa in the south-south west of the country. Five others, including one representative of the dentissima group of the Sophophora subgenus, D. usambarensis, and four representatives of the Drosophila subgenus, D. gata, D. neogata, D. paragata and D. pilocornuta, were found only in the Usambara Mts. Two of these five, D. usambarensis and D. pilocornuta were found only in West-Usambara, while two other related species, D. gata and D. paragata, were found only in East-Usambara. Only the distribution of D. neogata covers the whole of the Usambara mountains. Outside the Eastern Arc, another representative of the dentissima group, D. kilimanjarica, was found only on Mount Kilimanjaro. This new, highly specific, montane fauna of Drosophila further contributes to the unique biological diversity of the Eastern Arc Mts. The biogeographic affinities of the new taxa suggest past connections with the Virunga and Ruwenzori ranges and further west with the Cameroon Volcanic Line. It indicates, in particular, that the Eastern Arc forests have passed through a succession of coalescence and fragmentation events.
Seven new species of chewing lice in the genus Resartor Gustafsson et Bush, 2017 are described and illustrated. They are: Resartor albofulvus sp. n. ex Heterophasia desgodinsi desgodinsi (Oustalet); Resartor apimimus sp. n. ex Heterophasia picaoides wrayi (Ogilvie-Grant); Resartor aterrimus sp. n. ex Minla ignotincta mariae La Touche; Resartor extraneus sp. n. ex Lioparus chrysotis swinhoii (Verreaux); Resartor guangxiensis sp. n. ex Trochalopteron milnei sinianum Stresemann; Resartor longisuturalis sp. n. ex Actinodura cyanouroptera wingatei (Ogilvie-Grant); Resartor seminudus sp. n. ex Leiothrix argentauris tahanensis (Yen). All species differ in the shape of the head, shape of the male genitalia and abdominal chaetotaxy. A checklist and a key to the species of Resartor are provided., Daniel Roland Gustafsson, Xingzhi Chu, Sarah Elizabeth Bush, Fasheng Zou., and Obsahuje bibliografii
For many important research topics in polymer science the use of radionuclides brings significant benefits concerning nanotechnology, polymer drug delivery systems, tissue engineering etc. This contribution describes important achievements of the radionuclide laboratory at Institute of Macromolecular Chemistry of the Academy of Sciences of the Czech Republic (IMC) in the area of polymers for biomedical applications. Particular emphasis will be given to water-soluble polymer carriers of radionuclides, thermoresponsive polymer radionuclide carriers, thermoresponsive polymers for local brachytherapy, polymer scaffolds modified with (radiolabeled) peptides and polymer copper chelators for the therapy of Wilson´s disease., M.

This paper deals with four types of point estimators based on minimization of information-theoretic divergences between hypothetical and empirical distributions. These were introduced
\begin{enumerate} \item[(i)] by Liese and Vajda \cite{9} and independently Broniatowski and Keziou \cite{3}, called here \textsl{power superdivergence estimators, } \item[(ii)] by Broniatowski and Keziou \cite{4} , called here \textsl{power subdivergence estimators, } \item[(iii)] by Basu et al. \cite{2}, called here \textsl{power pseudodistance estimators, }and \item[(iv)] by Vajda \cite{18} called here \textsl{Rényi pseudodistance estimators.} \end{enumerate}
These various criterions have in common to eliminate all need for grouping or smoothing in statistical inference. The paper studies and compares general properties of these estimators such as Fisher consistency and influence curves, and illustrates these properties by detailed analysis of the applications to the estimation of normal location and scale.
We make some comments on the problem of how the Henstock-Kurzweil integral extends the McShane integral for vector-valued functions from the descriptive point of view.
We establish that the inequality of Radon is a particular case of Jensen's inequality. Starting from several refinements and counterparts of Jensen's inequality by Dragomir and Ionescu, we obtain a counterpart of Radon's inequality. In this way, using a result of Simić we find another counterpart of Radon's inequality. We obtain several applications using Mortici's inequality to improve Hölder's inequality and Liapunov's inequality. To determine the best bounds for some inequalities, we used Matlab program for different cases.
When proposing and processing uncertainty decision-making algorithms of various kinds and purposes, we more and more often meet probability distributions ascribing non-numerical uncertainty degrees to random events. The reason is that we have to process systems of uncertainties for which the classical conditions like σ-additivity or linear ordering of values are too restrictive to define sufficiently closely the nature of uncertainty we would like to specify and process. In cases of non-numerical uncertainty degrees, at least the following two criteria may be considered. The first criterion should be systems with rather complicated, but sophisticated and nontrivially formally analyzable uncertainty degrees, e. g., uncertainties supported by some algebras or partially ordered structures. Contrarily, we may consider easier relations, which are non-numerical but interpretable on the intuitive level. Well-known examples of such structures are set-valued possibilistic measures. Some specific interesting results in this direction are introduced and analyzed in this contribution.
The growth in the experimental research of facilities to support extracorporeal circulation requires the further development of models of acute heart failure that can be well controlled and reproduced. Two types of acute heart failure were examined in domestic pigs (Sus scrofa domestica ): a hypoxic model (n=5) with continuous perfusion of the left coronary artery by hypoxic deoxygenated blood and ischemic model (n=9) with proximal closure of the left coronary artery and controlled hypoperfusion behind the closure. The aim was a severe, stable heart pump failure defined by hemodynamic parameters changes: a) decrease in cardiac output by at least 50 %; b) decrease in mixed venous blood saturation to under 60 %; c) left ventricular ejection fraction below 25 %; and d) decrease in flow via the carotid arteries at least 50 %. Acute heart failure developed in the first group in one animal with no acute mortality and in the second group in 8 animals with no acute mortality. In the case of ischemic model the cardiac output fell from 6.70±0.89 l/min to 2.89±0.75 l/min. The saturation of the mixed venous blood decreased from 83±2 % to 58±8 %. The left ventricular ejection fraction decreased from 50±8 % to 19±2 %. The flow via the carotid arteries decreased from 337±78 ml/min to 136±59 ml/min (P≤0.001 for all comparisons). The proposed ischemic model is not burdened with acute mortality in the development of heart failure and is suitable for further use in experimental research into extracorporeal circulatory support., S.
