Opis:
The palaeoecology and palaeoenvironments of the lower–middle Miocene succession in Gebel Gharra, NW of Suez, Egypt, are interpreted, on the basis of a detailed study of microfacies, trace fossils, and macrofaunal benthic assemblages. This succession consists of a lower siliciclastic part (the Gharra Formation) and a carbonate-dominated upper part (the Geniefa Formation), corresponding to a general transgression-regression cycle. Facies characteristics indicate depositional palaeoenvironments, ranging from supratidal, lagoonal, to shoal settings on an inner ramp that was influenced proximally by clastic input. At least seven ichnotaxa were recorded in the lower Miocene Gharra Formation, representing suites of the Skolithos ichnofacies. Among them, the ichnogenus Polykladichnus is recorded for the first time in Egypt. The macrobenthic taxa identified in 13 statistical samples are grouped into five assemblages (A–E) that are described and interpreted as the remains of communities. The faunal distribution and trophic structure of most of these assemblages confirm the existence of relatively stable and low-stress conditions. However, the trophic structure of the assemblages reflects the influence of particular environmental parameters, the dissolution of aragonitic shells and/or sample-size effects. Environmental parameters, controlling the distribution of trace and/or body fossils, include substrate consistency, bathymetry, water energy, productivity level, rate of sedimentation, salinity, and oxygen availability. The results of integrated lithoand biofacies analysis confirm that the succession studied was deposited in different environmental settings, providing perfect conditions for the occurrence and preservation of trace-fossil and macrobenthos assemblages.

Opis:
A large collection of the trace fossil Rhizocorallium from the Middle Triassic of the Polish part of the Germanic Basin (Peri-Tethys) is analysed and their ichnotaxonomical classification presented. Special attention is given to the deep form of Rhizocorallium with a vertical retrusive spreite, filled with faecal pellets, with detailed documentation of this structure, based on isolated specimens and serial sections. This analysis also reveals ∩-shaped and deep, protrusive structures. A former interpretation of Rhizocorallium as a rapidly formed fugichnion is not followed here; instead, an interpretation of the trace fossil as a complex fodinichnion is proposed. Scavengers and their relation to crinoid meadows, as well as predators, are indicated as potential tracemakers of some Rhizocorallium. Although Rhizocorallium is common throughout the Middle Triassic, unusual forms and the domination of substrates by Rhizocorallium in general mostly occur in the transgressive system of the lowermost Muschelkalk, and in regressive, marginal facies of the lower Keuper. Such a distribution of unusual forms of Rhizocorallium is interpreted as representing opportunistic, pioneer burrow assemblages that developed during the long-term benthic recovery after the P-T crisis, or in unfavourable conditions generally. Moreover, dynamic conditions with mixed clastic-carbonate sedimentation and rapidly varying salinity promoted smooth transitions from Rhizocorallium to Diplocraterion. Similar successions of dominant trace-fossil assemblages, of comparable sizes, occur in many sections around the world and demonstrate the record of slow recovery that continued through the Middle Triassic. The illustrated record of evolution of the Middle Triassic Rhizocorallium assemblages in Poland documents the last two stages of benthos recovery after the P-T boundary. A similar situation is observed around the world and, in many cases, great abundance of Rhizocorallium seems to be an indication of pioneer burrowing in dynamic, unfavourable environments.

Opis:
In order to evaluate the degree of sediment contamination by metallic trace elements in the watershed of Oued Inaouene (North-East of Morocco), samples of surface sediments were taken along the river and at the level of the Idriss 1st dam. The objective was to obtain thorough knowledge of the environment (metallic element content, organic matter content, granulometry, and pH, EC, CaCO3 content) in order to identify the degree of pollution in these sediments. The results of analysis have highlighted a contamination accentuated by Ba, Sr, P, Cu, Pb, In fact, this element is present at very high levels, with a maximum content ppm for the samples taken upstream of Oued Inaouene. This increase is related to the physicochemical conditions of the environment, despite the diversity of sources of pollutants. The analysis of hazardous heavy metals showed the values under the detection limits. The qualitative study allowed to identifying the source of contamination, it is an anthropogenic source related to the discharges of cities in vicinity of Oued Inaouene, and natural considered as the main source of pollution by trace elements of sediments that constitute an important reserve of pollutants in the environment.

We describe construction and investigation results of optical trace gas sensor working in the 3.334-3.337 μm spectral range. Laser spectroscopy was performed with a multipass cell. A setup was elaborated for detection of ethane at the 3.3368035 μm absorption line. Analysis of the gas spectra and the experiment have shown that, beside C2H6, the sensor is suitable for simultaneous detection of methane, formaldehyde and water vapor. Due to nonlinearity of the laser power characteristic we decided to detect the fourth harmonic of signal. Additional laser wavelength modulation was applied for optical interference suppression. In result, the precision of ethane detection of approximately 80 ppt has been achieved for the averaging time of 20 seconds. Long-term stability as well as the measurement linearity have also been positively tested. The system is suitable for detecting potential biomarkers directly in human breath.

Opis:
Over a long period of time, a huge amount of technogenic bottom sediments has been accumulating in the Kosva Bay with significant concentrations of amorphous iron and aluminium hydroxides, which, in turn, are active sorbents of pollutants. This study examines the distribution of trace elements and rare earth elements and their toxicity in the Kosva Bay of the Kama Reservoir (Perm Region, Russia). In the middle reach, the Kosva River crosses the Kizel coal basin, where acid mine water is discharged from closed mines. The average content of trace elements in the samples of bottom sediments of the bay varies from 0.10 mg/kg (Se) to 176.36 mg/kg (Ba). The amount of rare earth elements varies from 66.8 to 83.6 mg/kg. The ecological significance of trace elements and rare earth elements was studied using an element-by-element assessment (EF and Igeo), Potential Ecological Risk Index (RI), Mean Probable Effect Concentration Quotient (PECQ), and two bioassays (Daphnia magna Straus and Scenedesmus quadricauda (Turp.) Breb. The highest Hg enrichment was found at two sampling points. Taking into account the average value of Igeo, the pollution by Co, V, Nb, Hg, Sn, Zn, Sm, Ni, Cr, and Gd is the highest and corresponds to extremely contaminated category. The RI values indicate that pollution categories vary from moderate risk to considerable risk. According to mean PECQ values, bottom sediments of the bay have moderate potential toxicity towards biological communities. Results of chronic and acute toxicity on test objects D. magna and Scenedesmus quadricauda Breb show the water extract from bottom sediments having no effects on the test objects. The results of the study show that in order to assess the quality of bottom sediments, an integrated approach, combining chemical and ecotoxicological analyses, is needed.

Opis:
The Early Jurassic succession of the Holy Cross Mountains region in Poland offers a rare opportunity to study ecosystem complexity during the evolution and diversification of early dinosaurs, especially herbivorous ones. The section consists of continental and coastal deposits containing fossil assemblages spanning nearly 25 My of changes in terrestrial plants and some groups of invertebrates and tetrapods. Based on macrofossils and pollen and spores, the broader characteristics of the flora in this succession are presented. The floral assemblages show typical Early Jurassic characteristics and contain lycopsids, sphenopsids, ferns, cycadaleans, bennettitaleans, gnetaleans and ginkgoaleans, as well as conifers, and are similar to other Hettangian–Toarcian floral successions in Europe, showing the presence of a vast coniferous forest dominated by Hirmeriella in the early Hettangian, replaced by ginkgophyte-dominated floras in younger stages and araucarian conifer-dominated forests in the late Pliensbachian. Dinosaurs are documented mainly from their trace fossils (tracks and coprolites). Six distinct track assemblages (stratigraphically separated ichnoassemblages) of different ages can be identified. Current evidence indicates that while Anomoepus tracks are abundant throughout the long Hettangian–late Pliensbachian interval, medium-sized to large ornithischian tracks do not occur below the lower–middle Hettangian transition zone, associated with the first major marine transgression in the region. Hettangian strata with different theropod tracks (Grallator, Anchisauripus, Eubrontes, Kayentapus, cf. Megalosauripus), small Anomoepus tracks, numerous medium-sized Anomoepus-like tracks, Moyenisauropus tracks, tetradactyl tracks of sauropodomorphs (cf. Pseudotetrasauropus) and oval-shaped tracks of sauropods (Parabrontopodus) significantly contrast with the higher part of the Lower Jurassic succession (upper Pliensbachian Drzewica Formation and middle–upper Toarcian Borucice Formation) containing new types of medium-sized to large theropod tracks (Therangospodus), small and medium-sized bird-like tridactyl tracks (cf. Trisauropodiscus, cf. Anomoepus), exceptionally large, oval-shaped sauropod tracks (Sauropoda indet.), and new types of medium-sized and large ornithischian tracks (cf. Deltapodus, cf. Anomoepus). This points to a noticeable difference between the Hettangian and late Pliensbachian–Toarcian dinosaur ichnofaunas and may facilitate the study of regional and global changes and correlations. Both the palaeofloras and dinosaur trace fossils document ecosystem diversity and ecosystem changes, presented here in review form. The nature of these changes requires more detailed study, but preliminary results suggest the occurrence of rather complex and pronounced transformations in the dinosaur communities of the Holy Cross Mountains region. Based on our observations, the most significant event in Early Jurassic ecosystems took place within the Hettangian (change in floristic composition, the emergence of new groups of dinosaurs), but we also found what we believe to be a record of a major faunal turnover across the late Pliensbachian–middle–late Toarcian interval.

The precise determination of trace element concentrations in the soil of the Al-Qadisiyah Governorate is part of the Iraqi sedimentary plain is required to eliminate high levels of harmful elements in polluted soils. The soil samples were collected from 28 representative profiles in Al-Shamiyah city. The soil profiles were defined using virtual characterization. In this study, I-geo was used to analyze soil pollution. The goals and destinations of the I-geo readings Contamination of Cd, Ni, Pb, and Zn in various soil strata. I-geo (Cd) generally range from 0.58 to 4.71, I-geo (Ni) range from 0.09 to 4.07, I-geo (Pb) ranged range from 0.07 to 2.79, and I-geo (Zn) ranges from zero to 2.79, depicting the local differences in I-geo for pollutants in the research area. Suggesting that the research area had been heavily polluted from Cd in the varied layers of the soils. On the maps pertaining to Zn and Pb, the majority of the research area was primarily covered in the orange and blue hues, suggesting that a significant portion of the research area was likely to be severely polluted from Cd and Ni. Moreover, the land cover layouts of Ni in layers of the soils revealed concentrations rising towards to the western sections, which could be attributed to proximity to a major drain. The results display that its I-geo value of four trace metals generally range from non-pollute to significantly heavily polluted. The I-geo data show significant differences in levels of the Ni, Cd, Zn, and Pb in different soils strata. Including these findings, the soil in Al-Shamiya, Al-Qadisiyah Governorate contains high levels of Cd, Ni, Pb, and Zn. Industries of fossil fuel combustion, as well as other man-made wastes include agricultural nutrients, soil conditioners, and sludge, particularly, ammonium phosphate pollution in soils. The pollutant load index (PLI) reveals a baseline level of contamination in 28 locations, as well as a decline in soil quality in four others. Finally, assessing the danger of contamination for trace metals utilizing the I-geo and PLI by using the GIS method and multimodal models is a helpful and relevant strategy.

Opis:
The immobilization effect of soil amendments on leaching and bioavailability of Pb, Zn and Cd in highly contaminated soils under industrial impact was studied by collecting the soils in the surroundings of Zn-Pb Smelter “Miasteczko Śląskie” in southern Poland as an example. Various amounts of four additives (phosphate fertilizer, limestone powder, bentonite rock and bog iron ore) were tested in laboratory experiments to compare the effectiveness of three dominant mechanisms of immobilization: precipitation of phosphates, pH increase, and sorption. The contents of metals before immobilization were determined by extraction in CaCl2, EDTA and aqua regia. Cadmium and zinc are mainly represented by soluble, bioavailable forms extractable in CaCl2, while lead by potentially bioavailable speciations extractable by EDTA. Most effective in the immobilization of these metals were the amendments increasing soil pH: limestone powder and phosphate fertilizer. Bog iron ore and bentonite were less effective because the soil pH was too low for efficient cation adsorption.

Opis:
Geochemical studies of CO2-rich therapeutic waters in the Sudetes have provided new data on a wide range of trace elements, going beyond standard chemical analyses of such waters. A consistent set of physicochemical data obtained using the same analytical methods was subjected to statistical analyses, including hierarchical clustering, factor analysis and nonparametric tests (Kruskal-Wallis, Tau Kendall), to reveal geochemical relationships between physicochemical and chemical parameters in the waters, and their relationships with the aquifer lithology. Distinct differences in the composition of waters found in crystalline rocks (mainly gneisses and mica schists) and sedimentary rocks were identified. The wide range of elements can be associated with the hydrolysis of silicate minerals, including alkali and alkali earth metals (Li, Na, K, Rb, Cs, Be) and (mostly) transition elements (Fe, Mn, Zn, Co, W, Mg). Carbonate equilibria are the next important factor as it determines the aggressiveness of the water towards the minerals of aquifer rocks and affects the concentrations of numerous solutes. The probable common origin of chlorides, bromides and sulphates together with Li, Na, Sr may be related to the relict saline component of deep circulating waters, a hypothesis that requires further investigations.

Opis:
Le propos de cet article est de relever, dans une approche comparative, la versatilité du rôle des objets de collection dans le processus de remémoration chez les collectionneurs de certains romans de Pascal Quignard. L’analyse du discours mémoriel des collectionneurs relève deux aspects : un rapport différent à la valeur de l’objet (muséal ou intime) et le pouvoir de déclencher des émotions. Le discours balance entre une évocation impersonnelle, qui met l’accent sur l’importance matérielle, la dimension testimoniale et esthétique des objets d’art d’époques anciennes et une description passionnée et subjective de petits objets banals, mais chargés de significations psychologiques. L’article démontre que se rapporter excessivement aux objets-temps/trace en vertu de leur valeur documentaire ou commémorative débouchera sur un échec de la démarche mémorielle. Paradoxalement, le collectionneur reste toujours à la recherche de la mémoire perdue, malgré l’excès de preuves matérielles qu’il détient.
The purpose of this article is to highlight – in a comparative approach – the versatility of the role of collectibles in the process of recollection among collectors in certain novels by Pascal Quignard. The analysis of the memorial discourse of collectors reveals two aspects: the different relationship to the value of the object (museum or intimate) and the power to trigger emotions. The discourse balances between an impersonal evocation, with emphasis on the material importance, the testimonial and aesthetic dimension of art objects from ancient times and a passionate and subjective description of small, banal objects, but charged with psychological meanings. The article demonstrates that excessively relating to time-/trace-objects by virtue of their documentary or commemorative value will lead to a failure of the memorisation process. Paradoxically, the collector always remains in search of the lost memory, despite the excess of material evidence he holds.

Opis:
Autor „czyta” poezję Czesława Miłosza, podążając za pozostawionymi w niej włoskimi śladami. Są nimi zarówno echa udokumentowanych w biografii poety podróży do Włoch i po Włoszech, jak i tropy wywodzone z lektury włoskich pisarzy, fascynacji malarstwem, architekturą oraz ukształtowanym przez człowieka pejzażem. Wszystkie te tropy – jak się okazuje – wprowadzają w najistotniejsze motywy poezji autora Gucia zaczarowanego, a także w zasadnicze dla tej poezji elementy tradycji literackiej. Są też obrazem ewolucji poetyki Miłosza. Esej napisany jest w poetyce fragmentu, jego autor raczej dzieli się interpretacyjnymi intuicjami, niż stawia jednoznaczne konkluzje. Raczej stawia pytania o tajemnice zawarte w wierszach Miłosza, niż udziela jednoznacznych i zamykających odpowiedzi. Niejako „zaprasza” do studiowania wierszy autora Trzech zim. Te włoskie „ślady” prowadzą jednak do konkluzji o spójności dzieła poetyckiego Miłosza.
L’autore “legge” la poesia di Czesław Miłosz, seguendo le impronte italiane lasciate in essa. Sono sia echi di viaggi in Italia e in giro per l’Italia documentati nella biografia del poeta, che tracce derivate dalla lettura di scrittori italiani, dal fascino per la pittura, l’architettura e il paesaggio modellato dall’uomo. Tutti questi indizi – come risulta  – ci introducono ai motivi più significativi della poesia dell’autore di Gucio zaczarowany, così come agli elementi della tradizione letteraria che sono fondamentali per quella poesia. Sono anche un’immagine dell’evoluzione della poetica di Miłosz. Il saggio è scritto nella poetica di un frammento, con l’autore che condivide le sue intuizioni interpretative piuttosto che fornire conclusioni inequivocabili. Egli pone domande sui misteri contenuti nelle poesie di Miłosz, piuttosto che fornire risposte inequivocabili e definitive. In un certo senso, “invita” a  studiare le poesie dell’autore di Trzy zimy. Queste “tracce” italiane, tuttavia, portano a  una conclusione sulla coerenza dell’opera poetica di Miłosz.
The author interprets Czesław Miłosz’s poetry, following the Italian traces left in it. These are both echoes of travels to Italy and traces derived from reading Italian writers, fascination with painting, architecture and the landscape shaped by man. All these traces introduce the most important motifs of the poetry of the author of “Gucio Enchanted,” as well as the essential elements of the literary tradition for this poetry. They are also an image of the evolution of Miłosz’s poetics. The essay is written in the poetics of the fragment. Rather than drawing unambiguous conclusions, its author shares his interpretative intuitions. He carries out a careful inquiry into the secrets contained in Miłosz’s poems rather than presenting definitive answers. In a  way, it “invites” you to study the poems of the author of “Three Winters.” These Italian “traces” lead, however, to the conclusion about the coherence of Miłosz’s poetic work.

The recent deterioration of the ecological condition of agricultural lands, the tendency of reducing soil fertility, and the production of plant products, mostly of low quality, necessitate an understanding of the role of trace elements in the process of plant formation. The content of trace elements in soils affects the efficiency of absorption of basic nutrients by plants. Deficiency of iron, manganese and zinc reduces the supply of nitrogen to plants. Copper and calcium promote the absorption of phosphorus by plants, but excess of iron inhibits it. Excess of copper and molybdenum reduces the transfer of potassium to plants. Due to high yields of agricultural crops, a significant amount of trace elements is removed from the soil, so the introduction of the optimal amount of trace elements against the background of high agricultural technology is an additional measure to increase the yields and quality of agricultural products. Heavy metals are an important environmental factor, which, on the one hand, is necessary for living organisms, and on the other (with increasing concentration of these elements in the environment) constitutes a negative factor in their lives. The activities of industrial enterprises, car exhausts and other attributes of civilization, increase the content of heavy metals in soils and as a consequence negatively affect their quality. The term “heavy metals” is used for the metals with a specific gravity exceeding 5 g/cm3 or an atomic number of more than 20. Among them, lead and cadmium are considered the most dangerous. Therefore, modeling the content of trace elements and heavy metals in the Steppe soils of Ukraine is an additional mechanism for quality control of agricultural land and, as a consequence, of obtaining quality products to ensure food security of the state.

Opis:
Celem artykułu jest przedstawienie potencjału badawczego w zakresie wizualizacji śladów, jaki daje zastosowanie najnowocześniejszego sprzętu mikroskopii cyfrowej będącego na wyposażeniu Laboratoriów Kryminalistycznych Komend Wojewódzkich Policji. Przedstawione w artykule metody pozwalają na analizę śladów w sposób dający nowe możliwości w ekspertyzach kryminalistycznych z zakresu broni i balistyki, a tym samym mający znaczący wpływ na wnioskowanie o materiale dowodowym i przebiegu zdarzenia. Słowa kluczowe: mikroskop cyfrowy, badania identyfikacyjne, wizualizacja śladów
The purpose of the article is to present the research opportunities, using visualization methods, provided by the use of state-of-the-art digital microscopy equipment on the equipment of the Forensic Laboratories of the Provincial Police Headquarters. The methods presented in the article allow for the analysis of traces in a way that provides new opportunities in conducting research in the course of performing forensic weapons and ballistics expertise, and thus have a significant impact on the inference of evidence and the course of the event.
