    Opis:
    The paper concerns a very rare and poorly known species of green alga Chlorodiscus natans Petersen & Hansen, discovered in the peat bog "Brzeźnik" near Bolesławiec (Poland). This is the second stand so far discovered in the world. The collected material allowed complementing the knowledge on organization of colonies, morphology and way of hair development. The remaining features, particularly the structure of the cell, are in concordance with the hitherto diagnosis of that species. The paper presents problems connected with the taxonomic affiliation of the species and describes the ecological conditions of habitats occupied by this alga.

    Opis:
    Hormotila ramosissima Korš., a very rare in the world and poorly known species, have been found in peat bogs of Lower Silesia. The growth stages typical of this species but unknown so far, have been described and illustrated. It was found that this species has many features in common with the representatives of Volvocales, Tetrasporales, and chlorococcales. The regularly observed zoospores and hemizoospores, which accompanied the various developmental stages of that species, showed an internal structure of Chlamydomonas-type. Studies on Hormotila ramosissima were based on live material collected in ample quantities from peat bogs. The collected in this way repeatable and abundant data allowed to discuss problems concerning morphology, reproduction and development, as well as consider the taxonomic position this species.

    Opis:
    The diversity of cyanobacteria and algae from various microhabitats in Spitsbergen is comparatively well known. However, the relationships between environmental factors and the structure of microflora communities remain largely unclear. This study was conducted in Hornsund Bay, which exhibits large variability in the physicochemical characteristics of habitats, particularly with regard to the availability of nitrogen and phosphorus. This variability, to a large degree, is caused by seabird colonies, which fertilize nutrient-poor terrestrial ecosystems near their nesting areas. The large variations in ecological conditions and vegetation types in the study area aid assessment of habitats representing different combinations of factors potentially influencing the formation of cyanobacterial and algal assemblages. The aim of this study was to examine the influence of physicochemical parameters on the taxonomic composition and diversity of green algae and cyanobacteria (particularly the coccoid, oscillatorialean, and heterocystous taxa). The study encompassed two groups of habitats – soil surface habitats and water-saturated habitats, both characterized by diverse influences of seabird colonies, vegetation cover, and moisture. Our results showed that taxonomic diversity and composition of cyanobacteria and algae were mainly influenced by P–PO₄³⁻, N–NH₄⁺ and Ca²⁺ (soil surface habitats), and NO₃⁻, as well as moisture (index of wetness) and pH (water-saturated habitats). The variability of these physicochemical properties was largely due to the variability of the seabird colony influence. Taken together, our findings aid in understanding the processes of formation of phycoflora assemblages in Arctic tundra.

    Opis:
    Oil and natural gas exploration is performed using geophysical methods and drilling works. In areas initially identified as prospective for the occurrence of accumulation oil or natural gas based on the analysis of geological data carried out geophysical surveys. The aim of this works is to identify geological structures that could constitute hydrocarbons traps. In the case of finding the appropriate structures, the next stage of exploration work is drilling well for further recognition of the structure. These works allow to explore not only the geological profile but also the physico-chemical properties of drilled rocks and reservoir fluids. Geophysical (mainly seismic) surveys and drilling works can affect the individual elements of the environment: the atmosphere, underground and surface water, ground surface and land and rock environment in different degrees. In order to estimate the risks, threats to all elements of the environment related to the prospection of hydrocarbon deposits have been analyzed (seismic and drilling works). Environmental risk is estimated based on a modified methodology contained in the norm PN 18002. For risks associated with the exploration referred to the consequences of adverse events in relation to the individual elements of the environment and the frequency thereof (by determining the probability of their occurrence). The risk was estimated by multiplying the weight of the likelihood of adverse events weights and consequences. Risk evaluation, indicating danger tolerated, acceptable and unacceptable was also evaluated

    Opis:
    Modelling experiment was used to investigate the abilities of using ground penetrating radar (GPR) to detect oil leaks in the underground pipeline system. Leaks not only waste precious natural resources but also create substantial damage to the transportation system within urban environments. Surface geophysical methods are noninvasive tools used to characterize the changes in the physical properties of the subsurface material. This characterization, in consequence, is used to interpret the geological and hydrogeological conditions of the strata. GPR is a reflection-based technique which uses high frequency electromagnetic waves to acquire subsurface information. GPR responds to changes in electrical properties, which are a function of soil and rock material and moisture content. A simple experiment was conducted to determine the validity and effectiveness of GPR technology in detecting leakage in metal pipelines. Initially, a prototype model was designed to simulate a pipe leak. A 1.5 GHz antenna modeling mode was used to collect GPR data. The test was modelled using sandy soil material that is representative for pipelines construction. Also model simulations are being used to select an appropriate equipment configuration (frequency band, type of antenna and real-time imaging software) prior to data acquisition.

    Opis:
    Industrial pipelines are used as a low-cost method of transport of various types of substances. In the last decades the number of transmission and distribution pipelines increased considerably, leading to an increased number of failures and rising the need for better and more accurate non-destructive methods of their detection and prevention. Leakage in pipeline networks causes a loss of valuable resources in the form of oil and gas. Repairing the infrastructure requires significant additional financial resources. Therefore, any damage to the pipeline network must be detected and repaired as soon as possible. Indirect methods for leak detection and localization uncover the presents of leaks from outside the pipeline by visual observation or by using appropriate equipment. Pipelines are often underground installations or run for many kilometers in areas where there are no roads, and access is extremely difficult or impossible. The underground occurrence of pipelines makes regular inspection difficult. It is also not possible to examine all pipeline sections simultaneously. Pipeline preventive maintenance or replacement program should be conducted based on detailed assessment of its technical and environmental conditions. Thus, safe and non-destructive techniques are needed, which would allow for pipeline periodical inspection without disturbing their operation.

    Nickel-free titanium alloys are a promising research direction in the field of biomedical materials. Current literature reports indicate that there is a possibility of using the Ti-Ta alloys in medicine since these alloys have had satisfactory results as far as biocompatibility, resistance to corrosion and mechanical properties are concerned, which is an important aspect while considering the use of this alloy for long-lasting bone implants. This article presents the results of a high-energy milling process with the use of Ti and Ta powders. The ball-milling process was carried out for various times, including 20, 40, 60, 80, and 100 h. The samples were characterized by X-ray diffraction, scanning electron microscopy, and transmission electron microscopy. The research confirmed partial synthesis of the materials during the process of high energy ball milling.

    The study presents the results of the influence of high energy milling on the structure of the new Ti-15Mo-5Sn [wt%] alloy for biomedical applications. During testing the powders were milled for the following milling times: 5, 15, 30, and 45 h. The milled powders were characterized by X-ray diffraction, scanning and transmission electron microscopy methods. Observation of the powder morphology after various stages of milling leads to the conclusion that with the increase of the milling time the size of the powder particles as well as the degree of aggregation change. However, a clear tendency of particles reduction at every stage of the mechanical alloying process is clearly observed. The X-ray diffraction results confirmed the presence of the α and β phases, and molybdenum. It has been found that the reflections from the Sn phase disappeared after five hours of milling, suggesting that the Sn and Ti alloying took place, leading to the creation of a titanium-based solid solution. After 30 and 45 h of mechanical alloying the formation of the β-Ti phase, the final share of which is 46(4) wt%, was observed. Furthermore, it was found that a diffraction line broadening with the increase of the milling time results from reduction of the crystallite size and an increase in the lattice distortion. The maximum level of the reduction of the crystallite size was obtained after 45 h of milling. The maximum degree of the unit cells reduction for all phases present in the powder that was being milled was also observed for this milling time.

    Opis:
    Ceramic injection moulding and gas pressure infiltration were employed for the manufacturing of alumina/AlSi10Mg composites. Porous ceramic preforms were prepared by mixing alumina powder with a multi-binder system and injection moulding of the powder polymer slurry. Then, the organic part was removed through a combination of solvent and thermal debinding, and the materials were finally sintered at different temperatures. The ceramic preforms manufactured in this way were infiltrated by an AlSi10Mg alloy. The microstructure and properties of the manufactured materials were examined using scanning electron microscopy, mercury porosimetry and bending strength testing. The results of transmission electron microscopy and scanning electron microscopy observations show that the fabricated composite materials are characterised by the percolation type of the microstructure and a lack of unfilled pores with good cohesion at the metal-ceramic interfaces. This is surprising considering that over 30% of the pores are smaller than 1 μm. The results show that the bending strength of the obtained composites decreased with increasing sintering temperature of the porous preforms.

    The paper presents the results of the Bi₅Ti₃FeO₁₅ multiferroic phase stability analysis during high-energy ball milling aimed at obtaining fine dispersion ceramic powder. The X-ray diffraction and transmission electron microscopy methods were used to analyse the structure and verify the degree of crystallite dispersion. Structural data analysis was carried out using the Rietveld method. To carry out the analysis of the morphology, the scanning electron microscopy was used. The results that were obtained showed that the high energy ball milling process results in the decomposition of the initial ceramics, where finally Bi₅Ti₃FeO₁₅ and Bi are obtained. An increase in the proportion of the amorphous phase and an increase in the dispersion of the grains and crystallites of the powder that occurs with an increase in the milling time were observed.

    Opis:
    In the paper results of the microstructure and mechanical properties (HB, Rm and R0,2) of AlSi17Cu5 alloy, subjected by solution heat treatment (500ºC/6h/woda) and aging (200ºC/16h/piec) are presented. In next step the alloy was modified and heated significantly above the Tliq temperature (separately and together). It was found that the increase in the strength properties of the tested alloy after heat treatment compared to alloys without solution heat treatment and aging was due to precipitation hardening. The applied aging treatment of ingots (preceded by solution heat treatment), causes not only increase in concentration in α(Al) solid solution, but also a favorable change of the primary Si crystals morphology. During stereological measurements significant size reduction and change in the morphology of hypereutectic silicon crystals ware found. This effects can be further enhanced by overheating the alloy to a temperature of 920ºC and rapid cooling before casting of the alloy.
    W pracy przedstawiono wyniki badań mikrostruktury i właściwości mechanicznych (HB, R,m i R0,2) odlewów ze stopu AlSi17Cu5 poddanych przesycaniu (500ºC/6h/wrząca woda) i starzeniu (200ºC/16h/piec) po procesie modyfikowania i znacznego przegrzania powyżej temperatury Tliq. (oddzielnie oraz łącznie). Stwierdzono, że podwyższenie właściwości wytrzymałościowych badanego stopu po obróbce cieplnej w stosunku do odlewów bez przesycania i starzenia nastąpiło na skutek utwardzania wydzieleniowego. Zastosowany zabieg starzenia poprzedzony przesycaniem, wywołuje nie tylko wzrost stężenia w roztworze stałym α(Al), ale też korzystną zmianę morfologii pierwotnych kryształów krzemu. Na podstawie pomiarów parametrów stereologicznych stwierdzono istotne zmniejszenie i zmianę morfologii nadeutektycznych kryształów krzemu, co dodatkowo można zintensyfikować przegrzaniem stopu do temperatury 920ºC i szybkim chłodzeniem przed odlaniem.
