The settlement at Milanówek/Falęcin is a part of large centre of iron production of the Przeworsk Culture, dating from the Late Pre-Roman and Roman Periods, and located in the western Masovia (central Poland). The site was discovered in the 1960s during surface surveys, and its area is estimated to 9–12 hectares. Over time, various non destructive archaeological methods have been employed at the site (e.g. aerial photography, geomagnetic surveys, advanced surface prospection), and excavations were carried out over an area of ca 1500 m2 . There have been found remains of nearly 1000 slag pit furnaces, 4 lime kilns, 1 ‘horseshoe-shaped’ kiln, 2 buildings and several pits. The excavation yielded also a large set of artefacts, of which some were subjected to expert analysis (e.g. chemical composition of slags, mineralogical composition of clay of relic of shafts). On the basis of geomagnetic surveys and excavations it is presumed that the settlement at Milanówek Falęcin may contain remains of about fifteen thousand slag-pit furnaces. and Osídlení v Milanówek-Falęcinu bylo součástí rozsáhlého centra výroby železa převorské kultury, nacházející se v západním Mazovsku (střední Polsko) a pocházející z pozdního předřímského a římského období. Lokalita byla objevena v šedesátých letech 20. století pomocí povrchových průzkumů a její plocha se odhaduje na 9–12 hektarů. V průběhu času byla lokalita zkoumána různými nedestruktivními archeologickými metodami (např. letecké snímkování, geomagnetické průzkumy, povrchová prospekce), výkopové práce byly provedeny na ploše ca 1500 m2 . Odkryty byly relikty téměř tisícovky pecí se zahloubenou nístějí, čtyři vápenické pece, pec ve tvaru podkovy, stopy dvou nadzemních staveb a několik jam. Výkopy přinesly také velký soubor artefaktů, z nichž některé byly podrobeny odborné analýze (např. stanovení chemického složení strusek a mineralogického složení hlíny reliktů šachet pecí). Na základě geomagnetických průzkumů a výkopů se předpokládá, že osídlení v lokalitě Milanówek-Falęcin může obsahovat pozůstatky zhruba patnácti tisíc pecí se zahloubenou nístějí.
Hypothermia was shown to attenuate ventilator-induced lung injury due to large tidal volumes. It is unclear if the protective effect of hypothermia is maintained under less injurious mechanical ventilation in animals without previous lung injury. Tracheostomized rats were randomly allocated to non-ventilated group (group C) or ventilated grou ps of normothermia (group N) and mild hypothermia (group H). After two hours of mechanical ventilation with inspiratory fraction of oxygen 1.0, respiratory rate 60 min-1 , tidal volume 10 ml·kg-1 , positive end-expiratory pressure (PEEP) 2 cm H 2 O or immediately after tracheostomy in non-ventilated animals inspiratory pressures were recorded, rats were sacrificed, pressure-volume (PV) curve of respiratory system constructed, bronchoalveolar lavage (BAL) fluid and aortic blood samples obtained. Group N animals exhibited a higher rise in peak inspiratory pressures in comparison to group H animals. Shift of the PV curve to right, higher total protein and interleukin- 6 levels in BAL fluid were observed in normothermia animals in comparison with hypothermia animals and non-ventilated controls. Tumor necrosis factor- α was lower in the hypothermia group in comparison with normothermia and non-ventilated groups. Mild hypothermia attenuated changes in respiratory system mechanics and modified cytokine concentration in bronchoalveolar lavage fluid during low lung volume ventilation in animals without previous lung injury., P.

The aim of the paper is to introduce and study a new class of spaces called mildly (1, 2)∗ -normal spaces and a new class of functions called (1, 2)∗ -rg-continuous, (1, 2)∗ - R-map, almost (1, 2)∗ -continuous function and almost (1, 2)∗ -rg-closed function in bitopological spaces. Subsequently, the relationships between mildly (1, 2)∗ -normal spaces and the new bitopological functions are investigated. Moreover, we obtain characterizations of mildly (1, 2)∗ -normal spaces, properties of the new bitopological functions and preservation theorems for mildly (1, 2)∗ -normal spaces in bitopological spacesThe aim of the paper is to introduce and study a new class of spaces called mildly (1, 2)∗ -normal spaces and a new class of functions called (1, 2)∗ -rg-continuous, (1, 2)∗ - R-map, almost (1, 2)∗ -continuous function and almost (1, 2)∗ -rg-closed function in bitopological spaces.
