Opis:: Luminescence and excitation spectra of the systems on the basis of the nanoporous glass impregnated with KBr-TlBr and TlBr solutions as well as KBr single crystals surface-doped with thallium were studied in visible and ultraviolet regions at T = 77 K. It was shown that each of the studied systems has its peculiar optical properties, which differ from those of the corresponding macroscopic single crystals. The results are discussed taking into account the physicochemical features of the thallium insertion in the preparation of samples from solutions.

Opis:: The paper presents results of studies focused on occurrence and correlation of four main horizons of Younger Loesses: Lowest Younger Loess (LMn – after Maruszczak, 2001), Lower Younger Loess (LMd), Middle Younger Loess (LMs), and Upper Younger Loess (LMg) recorded in five sections (Politów, Wąchock, Nietulisko Małe, Komorniki and Bodzechów) in the Holy Cross Mountains area. All analysed loesses were accumulated during the Vistulian Glaciation (Weichselian). The horizons were distinguished based on separating interstadial tundra soils, coupled with thermoluminescence dating, and correlated with marine oxygen-isotope stages MIS 5d−2. The Lowermost Younger Loess (LMn) covers the Nietulisko I soil complex (Jersak, 1973), developed on deposits of the Odranian Glaciation (MIS 6) and representing a forest soil of the Eemian Interglacial (MIS 5e) and the Brørup warming (MIS 5c). A thin horizon of the Oldest Younger Loess and a thin sandy horizon, both probably corresponding to the Herning cooling phase (MIS 5d) at the boundary with the Eemian Interglacial, were distinguished within this complex. Based on previously performed grain-size and heavy mineral analysis of the Upper Younger Loess (LMg) and a topographic position of the loesses in four loessy islands of diverse regional extent, accumulation of this loess in the Holy Cross Mountains area is found to have been stimulated by the western winds. The proposed model of loess accumulation takes into account the influence of the topography of the area and its geological structure.

Opis:: The Wąchock section (N part of the Holy Cross Mountains) is bipartite, with a sub-loess lower part and a loess upper part. The sub-loess part lying on Lower Triassic sandstones includes fluvial, glacial and ice-dammed lake deposits, TL-dated at 352 ky BP to 157 ±23 ky BP. They represent the Mazovian (MIS 11) (Zbójnian?, MIS 9?) Interglacial and the Odranian Glaciation (MIS 6). The upper part comprises loesses intercalated with palaeosols, which reach a total thickness of 9 m and have TL ages at 148 ±23 ky BP to 15.8 ±8 ky BP. This part of the succession begins with horizon B of a brown soil from the Eemian Interglacial (MIS 5e) with an interstadial black soil from the oldest Vistulian (MIS 5c). Four younger loess horizons from the middle and younger Vistulian occur above; loesses with arctic and tundra palaeosols correspond to younger isotope stages (MIS 5b-MIS 2). The loess and palaeosol horizons distinguished in Wąchock were correlated with loess sections in Poland (Zwierzyniec and Polanów Samborzecki) and western Ukraine (Kolodiiv 3), showing large similitarities of both loesses and palaeosols. Due to this, the Wąchock site is proposed as a one of key sections for Vistulian loess sequences not only in the Holy Cross Mts. region but also in Central Europe. Palaeomagnetic studies of the Wąchock loesses have registerered palaeomagnetic inclinations with values lower than the average values expected in this locality (63°).

Opis:: Nineteen samples were collected from four loess profiles: Dybawka, Tarnawce, Dankowice and Biały Kościół for purposes of TL and OSL dating. The samples were collected from loess, interstadial fossil soil, Eemian soil and Holocene soil. The results were presented in the form of TL=f (OSL) date chart. The majority of TL dates are older than OSL dates. The results of LMg luminescence dating run parallel to the straight line of equal ages. The chart shows a high similarity of TL and OSL dates. The results are consistent with the stratigraphic diagnosis. Loess grains frequently show an age heterogeneity (two or more OSL dates are provided for a single sample).

Opis:: The genesis of the Vistula Spit (Southern Baltic Sea) in the Postlitorina period is regarded as occurring by gradual addition of successive dune ridges along the entire length of the form. Based on the degree of soil profile development and radiocarbon dating of organic sediments three main stages of aeolian processes are usually recognized. GIS analysis of a digital elevation model (DEM) and thermoluminescence dating of dune sand supports the model of progressive development of dune ridges, and has identified four periods of intense aeolian activity. These were established 5860–5400, 1930–1610, 1200–900 years ago from the present, and from 500 years ago.

Opis:: The European loess profiles provides evidence of changes in climate in the last glacial cycle. The final stage of loess accumulation took place in the youngest part of the last glacial (28 to 12 ka BP). Loess accumulated in two periods: from 28 to 18 ka BP and from 18 to 13 ka BP. These two stages were separated by a short phase of weaker aeolian activity and weak pedogenesis (initial tundra gleyed soils). The loess sedimentation rate can be defined as a mass accumulation rate (MAR ex pressed in g/m2/year). This value was calculated by Frechen et al. (2003) for several dozen loess sites across western and central Europe. In this paper we calculate the MAR for several loess sites in Poland and Ukraine. The MAR distribution across Poland and Ukraine is uneven in these two intervals. The MAR values oscillate between 100 to several thou sand g/m2/year. They markedly in crease eastwards, which may be explained by the latitudinal gradient of periglacial climate in the LateWeichselian (= Late Vistulian). The MAR distribution along a N-S trend confirms its large range in western and central Europe. However, the most easterly profiles (Polish and Ukrainian ones) show less variable thick nesses as the MAR was stable at a relatively low level from several hundred to more than a thou sand g/m2/year. This stability of the MAR characterized both loess-forming intervals in this part of Europe.

Opis:: Stratified sands, which are components of the glacial and interglacial Vilkišks and Tartokai profiles (Lithuania), were used as research material for experimental dating with the TL method. Sieve analyses of samples collected from stratified sands show varying grain-sizes in the samples, with domination by different fractions indifferent samples. Four aliquot of grains of the same diameter were selected from each sample for further research by means of the additive, regeneration and R methods. The results showed some consistent patterns, which suggest a direction that future studies could take on these deposits samples. It is necessary, though, to examine grains which comprise a substantial percentage share in the total sample mass.

Opis:: The paper presents an extensive review investigating the practical aspects related to the use of single- number ratings used in describing the sound insulation performance of partition wall panels and practical complications encountered in precise measurements in extensive frequency range from 50 Hz to 5 kHz. SWOT analysis of various single number ratings is described. A laboratory investigation on a double wall partition panel combination revealed the significant dependence of STC rating on transmission loss at 125 Hz attributed to 8 dB rule. An investigation conducted on devising alternative spectrums of aircraft noise, traffic noise, vehicular horn noise and elevated metro train noise as an extension to ISO 717-1 Ctr for ascertaining the sound insulation properties of materials exclusively towards these noise sources revealed that the single-number rating Rw + Ctr calculated using ISO 717-1 Ctr gives the minimum sound insulation, when compared with Rw + Cx calculated using the alternative spectrums of aircraft noise, traffic noise, etc., which means that material provides a higher sound insulation to the other noise sources. It is also observed that spectrum adaptation term Cx calculated using the spectrum of noise sources having high sound pressure levels in lower frequencies decreases as compared to ISO 717-1 Ctr owing to significant dependence of Ctr at lower frequencies.

Opis:: VI międzynarodowe porównanie wiarygodności trzech najważniejszych metod analitycznych stosowanych do wykrywania napromieniowanej żywności zorganizowano w 2015 r. pod auspicjami Ministerstwa Zdrowia i Hiszpańskiej Agencji Bezpieczeństwa Żywności i Żywienia (AESAN) oraz Krajowego Centrum Żywności (CNA). W badaniu zatytułowanym „Międzynarodowe badanie porównawcze metodami Tl, PSL i EPR, 6 runda” brało udział dziewiętnaście specjalistycznych laboratoriów z kilku krajów europejskich. CNA jest doświadczonym laboratorium, posiadającym akredytację do wykrywania napromieniowanej żywności metodami thermoluminescencji (TL), fotostymulowanej luminescencji (PSL) i spektroskopii elektronowego rezonansu paramagnetycznego (EPR). Większość laboratoriów uczestniczących w porównaniu międzylaboratoryjnym posiada również taką akredytację. Asortyment produktów spożywczych dostępnych na rynku jest coraz szerszy, jednak nie wszystkie z nich są testowane pod kątem ich potencjalnego napromieniowania. Jest to istotny argument przemawiający za udziałem wszystkich laboratoriów w porównaniach międzylaboratoryjnych, takich jak obecnie przeprowadzane.
Under the auspices of the Ministry of Health and the Spanish Agency for Food Safety and Nutrition (AESAN) the National Food Centre (CNA) in 2015 has organised the 6th international exercise for testing the reliability of three most important analytical methods used for the detection of irradiated food. The study named ”Intercomparative exercise for quality assurance on Tl, PSL and EPR Irradiated food detection methods, 6 th Round” assembled nineteen specialized laboratories from several European countries. The organizing institution CNA possess accreditation for the detection of irradiated food and is experienced in thermoluminescence (TL), photostimulated luminescence (PSL) and electron paramagnetic resonance spectroscopy (EPR). It is also the case with most of participating laboratories. Presently the spectrum of food products found in the market is significantly extended and many of this products were not tested or validated whether their radiation treatment is detectable. This is a strong argument for the need of the organization of intercomparative studies as the present one.

Opis:: In this paper, we present the results of inter-comparison studies on identification of irradiated food carried out by the leading European laboratories from 1991 to 2018. In 1990s, the Federal Institute for Health Protection of Consumers and Veterinary Medicine in Germany played the leading role in the organization of the inter-laboratory tests on this subject. At the beginning of the present century, the Spanish Agency for Food Safety and Nutrition and Food National Spanish Centre took over this role. In total, 47 international tests were carried out in which nearly 500 samples of alimentary products were analysed in 37 laboratories from 14 European countries. The tests were aimed at proving the reliability of analytical methods – thermoluminescence (TL), photostimulated luminescence (PSL), and electron paramagnetic resonance (EPR) spectroscopy – for identification of specific irradiated food products and to control the analytical skills and experience of participating laboratories. The results made possible a discussion on why some irradiated food samples are more difficult for identification. In general, the tests showed that TL measurements of products such as herbs, nuts, peppers, and raisins, and EPR studies of fish and chicken bones, fresh strawberries, and dried fruits could be used as reliable control methods. The challenge that control laboratories are facing now, is related to the identifi cation of complex food products such as diet supplements or biopharmaceuticals, in which only some additives are irradiated.

Te piaszczysto-żwirowe aluwia korytowe, poziomo, przekątnie i rynnowo warstwowane, były składane przez rzekę roztokową w okresie kataglacjalnym stadiału warty (datowania TL: 127–119 ka). Ich uziarnienie i struktura są różne w rozszerzeniach i zwężeniach doliny, co uwarunkowane było zmienną energią przepływów i zróżnicowaniem subśrodowisk sedymentacji fluwialnej. W przełomowym odcinku doliny aluwia zostały przykryte przez bardzo gruboklastyczne osady proluwialne. W vistulianie (czynnik klimatyczny) i w ostatnich stuleciach (czynnik antropogeniczny) powierzchnia tej terasy uległa zwydmieniu.
The structure, texture and age of the sediments of the higher (5–12 m) terrace of the Kamionka river between Suchedniów and Rejów are presented. These horizontal and cross-bedded sandy-gravel channel alluvia were accumulated by a braided river during the end of the Wartanian stadial (TL datings: 127–119 ka). Their grain size and structure differ in the wide and narrow sections of the valley, which was caused by changes of flow energy and differentiation of sedimentological fluvial subenvironments. Alluvia were covered by very coarse colluvia in the gap section. Dunes formed on top of the terrace in the Vistulian (climatic factor) and the last centuries (anthropogenic factor).
