    Dane badawcze dotyczą wpływu mezoporowatej krzemionki o typie struktury MCM-41 na proces degradacji termicznej zaczynów cementowych. Wpływ MCM-41 sprawdzono poprzez dozowanie w ilości 0-2% względem masy cementu. Zakres badań obejmował charakterystykę surowców wyjściowych, tj. cementu i MCM-41. Zbadano skład chemiczny (XRF - fluorescencja rentgenowska), skład fazowy (XRD - dyfrakcja rentgenowska) i uziarnienie (PSD - metoda dyfrakcji laserowej).W celu zbadania degradacji termicznej zaczynów cementowych z MCM-41 wykonano badania wytrzymałości na ściskanie (fc), wytrzymałości na rozciągnie (fcf), gęstości właściwej (DS), gęstości pozornej (DA), składu chemicznego (XRF), składu fazowego (XRD), struktury porów powietrznych (MIP - porozymetria rtęciowa).

    Histopathological Analysis of Liver Tissues in olaparib-resistant PDX model treated with PARPi alone or in combination with a CHK1 inhibitorObjectives:To evaluate the effectiveness and side effects of the drugs in patient-derived xenograft (PDX) models, we examined whether ovarian tumor cells metastasized to the liver after therapy. Methods: Olaparib-resistant PDX tumors were treated with PARPi alone or in combination with a CHK1 inhibitor for histopathological analysis. The levels of Ki-67 (a proliferation marker) and CHK1 kinase phosphorylation at Ser345 were assessed. Hematoxilin and eosin staining (H&amp;E) staining was used to differentiate and visualize the detailed structure of tissue components. Results: An Hematoxilin and eosin (H&amp;E) based evaluation of the liver tissue from mice with olaparib-resistant ovarian cancer revealed no evidence of metastasis to the liver. Ki-67 and pCHK staining showed no changes in liver tissue, indicating the absence of metastases and confirming that the treatment did not induce hepatotoxic effects.The dataset includes microscopic images from IHC and H&amp;E staining of liver tissues.Folder and file list: Folder 1.

    Assessment of the impact of polystyrene microplastics and soil moisture content on the bioavailability and mineralization of diesel fuel by a bacterial community in sandy soil

    No full text
    This dataset was generated to assess the impact of polystyrene (PS) microplastics and soil water availability on diesel fuel biodegradation and the functional structure of soil microbial communities. The study aimed to verify whether microplastics influence xenobiotic bioavailability and degradation kinetics by acting as competitive sorbents in the soil matrix.The data were collected from a 365-day microcosm experiment conducted in sandy soil artificially contaminated with diesel fuel and inoculated with a well-characterized hydrocarbon-degrading bacterial consortium. Treatments varied by PS microplastic concentration (0–10%) and soil moisture levels (PWP, FC, SAT). The dataset includes mineralization rates (CO₂ evolution), physicochemical analysis of PS particles, water activity and functional and taxonomic metagenomic profiles of the microbial community. This data supports the conclusion that soil moisture, rather than microplastic presence, is the dominant factor influencing hydrocarbon degradation in contaminated soils.</p

    The deposited data were collected as part of the research project entitled ‘Wpływ złożonej modyfikacji fizykochemicznej środowiska glebowego na mobilność metali, metaloidów i herbicydów - badania laboratoryjne’, eng. ‘The impact of complex physicochemical modification of the soil environment on the mobility of metals, metalloids and herbicides - laboratory tests’, financed by the National Science Centre, Poland as part of the project under the OPUS 21 call (project no. 2021/41/B/NZ9/03059) as well as by the project “Efficiency of erosion control agrotechnologies for improvement of soil quality and water regime and mitigation of greenhouse gas emissions”, financed by the National Science Fund (project no. КП-06 H 46/1 2020).The main objective of the research was to determine the impacts of additives of various origin and composition on Polish (Eutric Cambisol) and Bulgarian (Epicalcic Chernozem) soils. Physicochemical and hydrophysical parameters including pH, variable surface charge, porosity, specific surface area, wettability, sorption capacity relative to trace metals, and water retention of soils were taken into account. A comprehensive assessment of the validity of using popular soil additives (natural and synthetic zeolite, zeolite-carbon composite, fly ash, biochar, vermicompost, divergan) in a real context was made.The research was conducted in the period from 1st April 2022 till 20th October 2023 at the Institute of Agrophysics, Polish Academy of Sciences in Lublin (Poland) as well as Nikola Poushkarov Institute of Soil Science, Agrotechnology and Plant Protection in Sofia (Bulgaria). The collection contains the results of studies on characteristics of soil modifiers, the changes occurred in the soils after modification as well as sorption mechanism of cadmium (Cd) ions on soils, modifiers and soil-modifier mixtures.The attached files have been compressed to *.zip format.

    No full text
    This dataset contains adsorption isotherm parameters for Cd(II) and Pb(II) based on Freundlich and Langmuir models, as well as selected physical and chemical soil properties, for a set of soil samples collected from various geomorphological forms characteristic of postglacial landscapes. These postglacial landscapes include areas shaped during two stages of glaciation: the Bielsk Plain near Orla and the Nidzica Upland (Warta Glaciation – MIS 6), and the Masurian Lakeland (Vistula Glaciation – MIS 2–5). The sediments forming landforms differ in lithology, due to various glacial processes, source material origins, and post-depositional surface processes such as weathering and organic matter accumulation, leading to distinct physicochemical properties. shaped during various Pleistocene glaciations and glacial phases. Parameters include Freundlich constants (K, b) and Langmuir constants (Am, K), along with the determination coefficients (R²) indicating model fit. Soil properties comprise pH, organic matter content, particle size distribution (sand, silt, clay), CEC, calcium carbonate content, and Fe/Al ratio. The data support comparative analyses of sorption capacity across different landforms and are intended for use in environmental, agricultural, or geochemical research.</p
