    Complete database of the oak regeneration census performed in 2022-2024 in abandoned agricultural land
    (2026-08) Bobiec, Andrzej
    Complete database of the oak regeneration census performed in 2022-2024 in abandoned agricultural land contains Excel spreadsheet including the cross-checked database of all records (oak seedlings/saplings) with their geographic coordinates. Besides basic biometric parameters (height, diameter of the root collar, diameter at breast hight, sread of crown), the table includes other qualitative traits. There is the box frame in the sheet with variables' definitions (in Polish) - sheet "DbRegAll-NCN". The second sheet "Delta-H" collects the data referring to the saplings' vertical growth rate.

    Appearance Comparison Is the Strongest Independent Correlate of Eating Disorder Risk among Adolescents
    (MDPI, 2026-08-03) Polak-Szczybyło, Ewelina
    Background: Previous studies have demonstrated associations between social media use, body image, and the risk of eating disorders. However, it remains unclear whether these associations are attributable to social media use itself or to processes related to how users perceive and respond to the content encountered on these platforms. Methods: This cross-sectional study included 750 secondary school students aged 17–18 years. Participants completed an author-developed questionnaire assessing social media use, the perceived influence of social media content on body image, and com-parisons of their own body shape with those presented on social media, as well as the Eating Attitudes Test (EAT-26). Results: TikTok was the most frequently used social media platform. An elevated risk of eating disorders (EAT-26 ≥ 20) was identified in 9.7% of participants. Greater perceived influence of social media content on body im-age and more frequent body shape comparisons were independently associated with higher EAT-26 scores and a greater likelihood of scoring ≥20 on the EAT-26. Conclu-sions: Body image-related processes, particularly comparisons of one’s own body shape with those presented on social media, may be more relevant to eating disorder risk than the amount of time spent using social media itself. These findings highlight the importance of preventive interventions focused on media literacy and reducing maladaptive appearance comparisons.

    Oak post-fire regeneration dynamics - field data
    (2026-07-29) Bobiec, Andrzej
    Approximately one hectare large lot of the post-agricultural area was subjected to grass burning in March 2026. All young oaks taller than 0.5 were identified and measured in the fire aftermath. For other woody species a simplified assessment was applied. Separate spreadsheets dedicated to oak and other species. Database contains geographic coordinats of trees. Detailed instruction in text boxes.

    Generation of Hydrogen Peroxide in Beer and Selected Strong Alcoholic Beverages
    (MDPI, 2025-01-20) Rak, Małgorzata; Mendys, Dawid; Płatek, Aleksandra; Sitarz, Oskar; Stefaniuk, Ireneusz; Bartosz, Grzegorz; Sadowska-Bartosz, Izabela
    The generation of hydrogen peroxide has been documented in various plant-based beverages, such as coffee, tea, herbal infusions and wine, as well in energy drinks containing ascorbate and in plant-based food. There are no data in the literature on the presence and generation of hydrogen peroxide in beer and strong alcoholic beverages containing plant material. This study aimed to examine whether beer and selected strong alcoholic beverages (brandy, whisky and fruit liqueurs) contain hydrogen peroxide. The presence of hydrogen peroxide was found in freshly opened brandy, whisky, liqueurs and most diluted beers; subsequent incubation in an air atmosphere led to the generation of hydrogen peroxide. The presence of the electron paramagnetic resonance (EPR) signal of the semiquinone radical and the generation of the superoxide radical demonstrated in selected alcoholic beverages by the superoxide dismutase-inhibitable reduction of Nitrotetrazolium Blue and oxidation of dihydroethidium are in agreement with the two-step mechanism of generation of hydrogen peroxide by the autoxidation of phenolics. These results broaden the list of beverages containing and producing hydrogen peroxide.
