Opis:
Search for new half-metallic ferromagnetic binary compounds composed of alkaline earth and III (boron) or IV (carbon) elements is reported. Ab initio all-electron density functional theory calculations in the generalised gradient approximation indicate possibility of half-metallic ferromagnetism. This is a new class of theoretically predicted hypothetical materials, without transition metal elements, not as yet discovered experimentally. Ferromagnetism is expected to be induced by suitable crystalline structure with lattice constant above some critical value. The predominant p electrons mechanism seems to be responsible for the formation and interactions of localised magnetic moments on boron or carbon atoms.

Opis:
Celem Projektu ASR-RID jest opracowanie wytycznych technicznych projektowania betonów o dużej trwałości, ze szczególnym uwzględnieniem zabezpieczenia przed wystąpieniem uszkodzeń spowodowanych reakcją AAR , tj. między NaOH i KOH a reaktywnymi minerałami w kruszywie. Przedmiotem badań są kruszywa ze złóż w rożnych regionach Polski. Reaktywność alkaliczna kruszyw jest oznaczana i oceniana przy wykorzystaniu komplementarnych metod, stosowanych w systemach oceny reaktywności kruszyw w wiodących technologicznie krajach. Projekt zakłada opracowanie kryteriów oceny reaktywności kruszyw, z możliwością wykorzystania w systemie kontroli produkcji i ich dostaw na potrzeby wytwarzania betonów drogowych. Ocena reaktywności zostanie zweryfikowana na podstawie ekspansji betonu w warunkach eksploatacyjnych.
The objective of the Project is to develop the technical guidelines for high durability concrete, particularly for damage prevention due to AAR. The investigation covers the range of mineral aggregates originating from various regions of Poland. The alkali reactivity is evaluated using a set of complementary methods used in technologically advanced countries. The criteria for aggregate reactivity categorization and proper selection will be developed including possibility of use in quality control systems for delivery to concrete production for highway pavements and bridges. Deleterious alkali-aggregate reaction will be also prevented by concrete mix design using a limit of active alkalies and mineral additives introduced with cement. The reactivity evaluation will be verified using the performance test.

Opis:
Late Devonian magmatism in the Pripyat Trough, Belarus was associated with the development of the intraplate Pripyat-Donets Palaeorift. Magmatic rocks belong to an alkali-ultrabasic-alkali-basaltoid suite. These are represented by explosive, effusive, subvolcanic and volcanic facies. The magmatic activity and rock composition changes from the periphery to the axial part of the Pripyat Trough, corresponding to the general trend of destructive processes in the rifting zone. Geodynamically, the Pripyat alkali-ultrabasic rocks represent a series of magmatic suites of the Pripyat-Donets palaeovolcanic region coinciding with a zone of disappearance of Late Devonian divergence processes in the south-west of the East European Craton.

Opis:
A thermo tolerant, feather-degrading, newly isolated actinobacterial strain Streptomyces minutiscleroticus DNA38 was investigated for its ability to produce keratinase. Maximum production (283.4 IU) of keratinase by Streptomyces minutiscleroticus DNA38 in starch chicken feathers medium under submerged bioprocess was observed at optimized conditions of pH 9.0 of the medium and 45 °C incubation temperature. Further, an enhanced production (435.8 IU) of keratinase was achieved employing response surface methodology. Combined interactive effect of starch (7.50 g/L), yeast extract (0.74 g/L) and chicken feathers (7.50 g/L) were found to be the critical process variables for enhanced production under central composite design. Chicken feathers showed a direct action and addition of starch and yeast extract to the medium proved effective for a significant increase in the production of keratinase. The purified keratinase was monomeric and had a molecular mass of 29 kDa. The enzyme activity was significantly inhibited after pH 9.0 and temperature 50 °C.

Opis:
To investigate the relationship between the alkaline phosphatase (ALP) network of the marrow stroma and the haematopoietic regeneration after mice whole-body irradiation. Materials and methods: Three groups of mice were irradiated with a non-lethal ionising radiation dose: the fi rst one received an intraperitoneal injection of Levamisole, ALP inhibitor, 24 h before irradiation; the second one received an intraperitoneal injection of Lisinopril, haematopoiesis inhibitor, 24 h before irradiation; the third was left untreated, but irradiated. The fourth group, untreated and not irradiated, was the control. The total surface occupied by ALP positive processes, revealed by means of ALP cytochemistry in the marrow area, was evaluated semi-quantitively. Nucleated bone marrow cells were also counted. Results: ALP network began to increase 24 h after irradiation to reach a maximum after 72 h, when the bone marrow was almost become completely empty of the haematopoietic cells. This increase advances the haematopoietic recovery. This process was substantially delayed when the mice were injected with Levamisole 24 h before irradiation. On the contrary, ALP network increased strongly since the fi rst day after irradiation when the mice were injected with Lisinopril 24 h before irradiation. Conclusions: These data have indicated that the haematopoietic recovery and repopulation of the bone marrow were advanced by the ALP network recovery.

Opis:
Widely distributed freshwater carbonate sediments, i.e., limestone, dolomitic limestone and dolomite, developed in inter-dune alkaline ponds of the Danube-Tisza Interfluve in the centre of the Carpathian Basin during the Holocene. The key parameters that determine the formation of any given type of carbonate mineral (calcite, dolomite) are temperature, evaporation rate, pH and ion concentrations, in addition to CO2 absorption by aquatic plants. CT analysis is capable of recording small-scale density variations attributable to compositional differences of sedimentary rocks. As the type and proportion of rock-forming minerals and other components is an artifact of past environmental and climatic conditions, CT values may act as potential palaeoenvironmental proxies. The present study compares variations in rock-forming components obtained for freshwater carbonates utilizing the CT method with already available geochemical and palaeoecological proxy data. Variations in molluscan ecology and isotope geochemistry, sedimentation times and CT-based rock density values all indicate the relevance of millennial-scale, climate-driven changes in carbonate formation. As previously observed, the emergence of colder conditions in the North Atlantic, which resulted in increased cyclonic activity and heavier rainfall in western Europe and the Danube watershed area between 10.3 and 9.3 kyr cal BP, resulted in the emergence of humid conditions favouring a rise in the groundwater table at our site and precipitation of calcite from pore waters as opposed to high-magnesium calcite. This is clearly reflected in a negative shift in CT density values in our dated rock samples.

Opis:
Agpaitic nepheline syenites have complex, Na-Ca-Zr-Ti minerals as the main hosts for zirconium and titanium, rather than zircon and titanite, which are characteristic for miaskitic rocks. The transition from a miaskitic to an agpaitic crystallization regime in silica-undersaturated magma has traditionally been related to increasing peralkalinity of the magma, but halogen and water contents are also important parameters. The Larvik Plutonic Complex (LPC) in the Permian Oslo Rift, Norway consists of intrusions of hypersolvus monzonite (larvikite), nepheline monzonite (lardalite) and nepheline syenite. Pegmatites ranging in composition from miaskitic syenite with or without nepheline to mildly agpaitic nepheline syenite are the latest products of magmatic differentiation in the complex. The pegmatites can be grouped in (at least) four distinct suites from their magmatic Ti and Zr silicate mineral assemblages. Semiquantitative petrogenetic grids for pegmatites in log aNa2SiO5 – log aH2O – log aHF space can be constructed using information on the composition and distribution of minerals in the pegmatites, including the Zr-rich minerals zircon, parakeldyshite, eudialyte, låvenite, wöhlerite, rosenbuschite, hiortdahlite and catapleiite, and the Ti-dominated minerals aenigmatite, zirconolite (polymignite), astrophyllite, lorenzenite, titanite, mosandrite and rinkite. The chemographic analysis indicates that although increasing peralkalinity of the residual magma (given by the activity of the Na2Si2O5 or Nds component) is an important driving force for the miaskitic to agpaitic transition, water, fluoride (HF) and chloride (HCl) activity controls the actual mineral assemblages forming during crystallization of the residual magmas. The most distinctive mineral in the miaskitic pegmatites is zirconolite. At low fluoride activity, parakeldyshite, lorenzenite and wöhlerite are stable in mildly agpaitic systems. High fluorine (or HF) activity favours minerals such as låvenite, hiortdahlite, rosenbuschite and rinkite, and elevated water activity mosandrite and catapleiite. Astrophyllite and aenigmatite are stable over large ranges of Nds activity, at intermediate and low water activities, respectively.

Opis:
The proteolytic activity of three Pseudomonas aeruginosa strains, ATCC 27853 - a reference strain, and two clinical isolates was tested. The activity was examined after culturing the bacteria in two different growth media: the minimal M9 medium and rich Luria-Bertani broth (LB). Based on zymograms and protease activity specific assays, it was concluded that the reference strain produced three proteolytic enzymes in the LB medium: protease IV, elastase B and elastase A, while alkaline protease was only produced in the M9 medium. The clinical isolates of P. aeruginosa produced elastase B and alkaline protease when grown in the LB medium and the minimal M9 medium, respectively. PCR analysis confirmed the presence of both the lasB gene encoding elastase B and aprA coding for alkaline protease in the genomes of the three P. aeruginosa strains analyzed. The expression of these genes coding for two important P. aeruginosa virulence factors was dependent on the growth conditions in all the strains studied. The contribution of the extracellular proteinases to the virulence of P. aeruginosa strains used in this study was investigated using an insect model, the greater wax moth Galleria mellonella.

Opis:
In the paper, three different physico-chemical pretreatment methods in relation to bioethanol production were compared. The wood of fast-growing poplar species (Populus deltoides x maximowiczii and Populus trichocarpa Torr. & A. Gray ex Hook) and corn stover were used as a feedstock. The chemical composition and enzymatic hydrolysis efficiency of the biomass before and after pretreatments were compared. On the basis of the results, it was concluded that the applied pretreatments changed the chemical composition of the raw materials. In the case of the acid and LHW (liquid hot water pretreatment) methods, up to 93.7% of hemicelluloses (especially pentosans) were removed. From among the selected pretreatment methods, the LHW and alkaline methods occurred to be the most interesting. Nevertheless, from the bioethanol production point of view, the LHW process of Populus deltoides x maximowiczii wood was the best because after enzymatic hydrolysis, high amounts of glucose (up to 600.9 mg/g pretreated biomass) and minor amounts of xylose (up to 37.9 mg/g pretreated biomass) were produced. Moreover, based on the chemical composition and sugar profile analysis, it was proved that the Populus trichocarpa wood also has a high potential for bioethanol production.

Opis:
Energy generation from biomass presents some serious problems like slagging, fouling and corrosion of boilers. To address these problems, demineralization of biomass is performed using different leaching agents. This study is focused on determining the influence of leaching agents and leaching time on the physiochemical structure of rice husk during demineralization. Dilute (5% wt) solutions of HCl and H2SO4 were used for the demineralization of rice husk separately with leaching time of 15, 60 and 120 minutes. It is shown that H2SO4 exhibited higher removal of alkali and alkaline earth metals (AAEM) comparatively as depicted by the 34.2% decrease in ash content along with an increase of 7.10% in the heating value. The acid has been seen to induce more notable changes in physiochemical structure as depicted by the FTIR spectra and SEM micrographs. The thermal degradation behavior of the demineralized rice husk has also been reported.

Opis:
In this review the roles of specific proteins during the first step of mineralization and nucleation are discussed. Mineralization is initiated inside the extracellular organelles-matrix vesicles (MVs). MVs, containing relatively high concentrations of Ca2+ and inorganic phosphate (Pgi), create an optimal environment to induce the formation of hydroxyapatite (HA). Special attention is given to two families of proteins present in MVs, annexins (AnxAs) and tissue-nonspecific alkaline phosphatases (TNAPs). Both families participate in the formation of HA crystals. AnxAs are Ca2+- and lipid-binding proteins, which are involved in Ca2+ homeostasis in bone cells and in extracellular MVs. AnxAs form calcium ion channels within the membrane of MVs. Although the mechanisms of ion channel formation by AnxAs are not well understood, evidence is provided that acidic pH or GTP contribute to this process. Furthermore, low molecular mass ligands, as vitamin A derivatives, can modulate the activity of MVs by interacting with AnxAs and affecting their expression. AnxAs and other anionic proteins are also involved in the crystal nucleation. The second family of proteins, TNAPs, is associated with Pi homeostasis, and can hydrolyse a variety of phosphate compounds. ATP is released in the extracellular matrix, where it can be hydrolyzed by TNAPs, ATP hydrolases and nucleoside triphosphate (NTP) pyrophosphohydrolases. However, TNAP is probably not responsible for ATP-dependent Ca2+/phosphate complex formation. It can hydrolyse pyrophosphate (PPi), a known inhibitor of HA formation and a byproduct of NTP pyrophosphohydrolases. In this respect, antagonistic activities of TNAPs and NTP pyrophosphohydrolases can regulate the mineralization process.

Modyfikacja składu prętów bazaltowych przez częściową zamianę włóknami węglowymi poprawiła ich odporność na działanie środowiska alkalicznego. Natomiast modyfikacja matrycy epoksydowej nanokrzemionką nie przyniosła spodziewanej poprawy odporności chemicznej.
Reinforcement bars made of fiber reinforced polymer composites (FRP ) is now considered as an alternative reinforcement to steel reinforcement. This article presents the results of resistance tests of reinforcing bars made of hybrid (basalt-carbon) FRP composites to an alkaline environment simulating the cooperation of the bar with concrete cover. Modification of the composition of basalt bars by partial replacement with carbon fibers improved their resistance to the alkaline environment. However, modification of the epoxy matrix with nanosilica did not bring the expected improvement of chemical resistance.
