Opis:
W artykule przedstawiono zagadnienie dotyczące wykorzystania kamer termowizyjnych do bezinwazyjnych badań stomatologicznych. Badania wstępne przeprowadzono dla kilku osób, dokonując pomiarów rozkładu promieniowania temperaturowego w obrębie dziąsła. Analiza wyników badań wykazała zmiany przepływu krwi w dziąśle, co oznacza, iż badania te mogą być pomocne w monitorowaniu przejściowych procesów zapalnych dziąseł. Ważnym zagadnieniem jest jednak dobór odpowiedniej metodyki przeprowadzania tych pomiarów.
One of the modern methods used in medicine are thermographic research. Since periodontal tissues are among the most vascularized in the human body, the use of a high-sensitivity thermal imaging camera would allow non-invasive assessment and early detection of pathological changes in the gum [2, 3]. The aim of the study was to evaluate the hemodynamic changes within the gums during orthodontic treatment using thermography research. The examination covered several generally healthy people aged 10-13 years, who were undergoing orthodontic treatment. Thermographic research concerned the incisors of the upper dental arch with clinically healthy periodontium. A cooled, high sensitivity thermal camera FLIR X6580sc was used for investigations. Based on the performed research and analysis of the results, it can be concluded that in the case of measurements taken after about 5 minutes from the initial test there cannot be observed any changes in the average temperature. However, these changes are visible after about 20 minutes after the application of orthodontic forces. Namely, the observed increase in the average temperature was about 1,5 C, which indicated the hemodynamic changes within the gums. Based on the obtained results it can be concluded that the thermographic research may be helpful in monitoring the transition of inflammatory processes through the gum in the treatment with permanent braces. However, the selection of an appropriate methodology for conducting these measurements is a very important issue.

Opis:
Different methods have been used to determine the stratigraphic position of Pleistocene alluvial deposits, particularly fluvial interglacial deposits. Near-surface deposits of a meandering river, developed in point-bar and oxbow lake facies, in the Samica River valley (near Łuków, eastern Poland) have been investigated. The fossil valley is incised into the till plain and the outwash. The fluvial succession is locally overlain by solifluction deposits. All the deposits underwent sedimentological analysis. The petrographic composition of basal till occurring in the vicinity of a fossil valley was determined with the method of indicator erratics. Fluvial deposits were examined by pollen analysis and plant macrofossil analysis of oxbow lake facies. Absolute dating methods were applied to the deposits (thermoluminescence methods: TL and additionally IRSL). Lithological differences between fluvial and the surrounding glaciofluvial deposits were identified and their lithostratigraphic position assigned. Petrographic analysis of till and palaeobotanical analyses of oxbow lake facies gave compatible results. Fluvial deposits were formed after the Sanian 2/Elsterian Glaciation, during the Mazovian/Holsteinian Interglacial. Luminescence dating of the fluvial deposits by the TLMAX method yielded the most relevant results (412-445 ka), which indicate that these deposits were formed during the end of the MIS 12 and beginning of the MIS 11 stage.

Opis:
The Saglek Block of the Nain Complex in Northern Labrador forms the westernmost part of the North Atlantic Craton. It is one of the few regions on Earth where early Archaean crust is preserved. It consists of regionally metamorphosed gneisses to either granulite-facies from 2.74 to 2.71 Ga or amphibolite-facies at ca. 2.70 Ga. The Saglek Block is dominated by two suites of metaigneous gneisses: the Uivak I TTG suite (>3.6 Ga) and the Uivak II augen gneisses (ca. 3.4 Ga). Four samples offelsic Uivak I orthogneiss were selected to petrographi- cal and mineralogical studies: Johannes Point Cove (L1419), TigigakyukInlet (L1434; L1440) and Big Island (L1443). Sample composition (granodiorite-tonalite) and mineralogy (mostly plagioclase and quartz, with minor K-feldspar and biotite, and accessory zircon and apatite) for three of the four samples are consistent with published data of the Uivak I gneiss. Sample L1434 contains ferroean diopside and hornblende, which are absent in the other samples. Based on detailed mineralogical analyses, authors concluded that more mafic sample, can not belong to the suite of the Uivak I gneisses. Most probably it represents the younger Uivak II. Further, geochronological study is going to be conducted to characterise both, Uivak I and Uivak II gneisses isotopically.

Opis:
There are few unresolved questions in the Earth Sciences which generate as much debate as the nature of the Hadean Earth: i.e. the rock record between the Earth’s formation and about 3.8 billion years ago. Current knowledge of the nature and origin of the earliest crust comes largely from studies of the mineral zircon (ZrSiO4). The oldest zircon grains on Earth (4.46 Ga) are found in Jack Hills, Australia. They represent a time capsule of what the Earth was like from ca. 4.4-4.0 Ga during the Hadean. The other ancien rocks (>3.8 Ga) are preserved in Antarctica, Canada, China, Greenland, Labrador, Western Australia and Swaziland, with the oldest known rochi on Earth from the Acasta gneiss in Northern Canada, dated at 4.03 Ga. Most likely, the second oldest rock record in the world (>3.9 Ga) may be derivedfrom the Nanok gneiss in the Nain Complex of the Saglek-Hebron area in the northern part of the Labrador Peninsula. Extensive investigation of these rocks will allowfurther characterizing the nature of the earliest preserved crust.

Opis:
In presented studies the photocatalytic decomposition of NOx on gypsum plates modified by TiO2-N,Cphotocatalysts were presented. The gypsum plates were obtained by addition of 10 or 20 wt.% of different types of titanium dioxide, such as: pure TiO2 and carbon and nitrogen co-modified TiO2 (TiO2-N,C) to gypsum. TiO2-N,C photocatalysts were obtained by heating up the starting TiO2 (Grupa Azoty Zakłady Chemiczne Police S.A) in the atmosphere of ammonia and carbon at the temperature: 100, 300 i 600ºC. Photocatalyst were characterized by FTIR/DRS, UVVis/DR, BET and XRD methods. Moreover the compressive strength tests of modified gypsum were also done. Photocatalytic activity of gypsum plates was done during NOx decomposition. The highest photocatalytic activity has gypsum with 20 wt.% addition of TiO2-N,C obtained at 300ºC.

Opis:
The conducted studies were focused on the development of the gypsum material exhibiting self-cleaning properties. To this end, the raw gypsum was mixed with unique TiO2-based photocatalysts, previously modified by nitrogen and/ or carbon doping. The photocatalytic activity of the obtained gypsum plasters was evaluated trough the degradation of model organic compound (Reactive Red 198) under UV-vis irradiation. The impact of the photocatalysts presence on the physicochemical properties of the obtained gypsum plasters was evaluated. Furthermore, the role of non-metals presence on the photocatalytic properties of the TiO2 was determined. It was confirmed that the addition of N,C co-modified titanium dioxide into gypsum bestows this material with self-cleaning properties. The highest dye removal rate was displayed by the gypsum plaster containing optimal amount (10 wt%) of co-modified TiO2/N,C photocatalyst, after 20 hours of UV-vis irradiation.

Opis:
The Volochysk site belongs to important and unique loess sites in the Podolia Upland (W Ukraine) because it contains relatively well-developed loess deposits representing the last and penultimate glacial cycles. This loess-palaeosol sequence consists of pedocomplex S1 (MIS 5) developed on loess L2, and loess L1 (MIS 4-2) with the palaeosols of lower, interstadial rank. In this sequence, different periglacial structures were found, including the largest ones of ice-wedge cast type. Different quartz and polymineral fractions separated from the samples collected in the Volochysk site were dated using luminescence methods (SAR OSL, post-IR IRSL and TL) in three Polish luminescence laboratories in Gdańsk, Gliwice and Lublin. In total, 69 luminescence dating results were obtained for 18 samples. The methodological and research aims were to carry out mutual verification of the obtained dating results as well as to analyse and interpret the differences between them, and to determine the age of distinguished deposit layers and the period of cryogenic activities. The luminescence dates of the sediments, which were deposited during MIS 2, 3 and 4, corresponded fairly well to the ages attributed to these stages. They also indicate the age of periglacial phenomena. However, the TL dates were generally older than the OSL ones, especially those obtained for the sediments deposited during MIS 5 and 6. The results of the research of the Volochysk sequence were compared with those obtained in past years for the loess deposits of the Volhynian Upland (north of Podolia) during similar inter-laboratory analyses conducted to determine their age. The results of OSL datings of the older deposits (MIS 5 and MIS 6) are underestimated irrespective of the used method, and the type (quartz, polymineral) and size of grains. Numerous attempts were made to explain this phenomenon, which, however, give no answer. It was only found that this underestimation corresponded to the equivalent dose value of ~150 Gy.

Opis:
Non-normative method for determining acoustic insulation of board materials. The paper presents a new method for the measurement of acoustic insulation against airborne sounds in the insulation and construction board materials used in wooden and brick buildings. The primary aim of the study was to simplify the design of a test stand, and thus of individual measurements, while maintaining the confidence level of the results. A series of measurements was performed to evaluate this method’s suitability for determining the acoustic insulation of board materials, and the resulting sound reduction index was analyzed with reference to the tested material and frequency of the generated sound. The study outcomes were found to be consistent with the principles of building acoustics and allowed for drawing preliminary conclusions on the insulating properties of various board materials and sets of materials used for the construction of building partitions.
Nienormatywna metoda wyznaczania izolacyjności akustycznej materiałów płytowych. W pracy zaprezentowano nową, opracowaną przez autorów metodę pomiaru izolacyjności akustycznej od dźwięków powietrznych płytowych materiałów konstrukcyjnych i izolacyjnych stosowanych w budownictwie drewnianym i murowanym. Celem pracy było przede wszystkim uproszczenie stanowiska pomiarowego, a tym samym sposobu przeprowadzania pomiarów jednostkowych, przy zachowaniu poziomu ufności otrzymanych wyników. Dla określenia przydatności prezentowanej metody do wyznaczania izolacyjności akustycznej materiałów płytowych dokonano szeregu pomiarów oraz analizy wyznaczonego na ich postawie wskaźnika izolacyjności akustycznej w zależności od rodzaju badanego materiału i częstotliwości generowanego dźwięku. Stwierdzono, iż uzyskane wyniki badań są zgodne z zasadami akustyki budowli i pozwalają na formułowanie wstępnych wniosków odnośnie izolacyjności poszczególnych materiałów płytowych oraz ich zestawów w konstrukcji przegród.

Opis:
Ammonia-modified TiO2 (TiO2/N), prepared in a pressure reactor was used as the well- active and longlife photocatalyst for the azo dye (Reactive Red 198) decomposition. The effect of aeration and the different value of the pH of the reaction medium on the photocatalytic degradation of Reactive Red 198 in water has been investigated. It has been reported that the degradation is greatly influenced by the reaction pH and the faster decomposition of azo dye took place at pH 3.5. When the solution was acidic, a larger amount of azo dye on the positively charged surface of TiO2 photocatalysts was adsorbed. From the obtained results it can be seen that the effectiveness of the decolourisation of the solution was faster by using the nitrogen-modified TiO2.

Opis:
The Western Outer Carpathians flysch of Poland comprises clasts of crystalline rocks representing source areas that supplied sedimentary basins with clastic material. Zircon from quartz syenite and granite cobbles representing the Silesian Ridge, the currently unexposed source area located at the southern margin of the Silesian Basin, yielded uniform U-Pb dates of 604š6 Ma and 599š6 Ma. These are interpreted as the age of igneous crystallization. Similarly, zircon from a gneiss cobble derived from the northern source terrain gave 610š6 Ma date, which is interpreted as the age of crystallization of the granitic protolith to the gneiss. The Neoproterozoic magmatism is interpreted to have occurred at the Gondwana active margin.
