Auxiliary Sciences in Archaeology, Preservation of Relics and Environmental Engineering

Investigation supported by AGH grant no 11.11.140.318 and private funds of Maciej Pawlikowski.Badania archeologiczne jaskiń Prachodna i Temnata prowadzone były w latach 80. XX wieku i posiadały charakter multidysciplinarny. Wyniki badań prowadzonych w trakcie ekspedycji zostały opublikowane w książkach i artykułach (Kozłowski, Laville, Ginter, 1992, Pawlikowski 1992, 2010, Sirakov 1992). Prezentowana publikacja jest poświęcona procesowi wietrzenia wapieni, w których występują wspomniane jaskinie oraz ich przeobrażeniu się w residuum zwane terra rossa. W 2014 roku prowadzono badania terenowe, natomiast laboratoryjne w 2015 roku. Na ich podstawie stwierdzono różne tempo chemicznego rozpuszczania różnych petrograficznych odmian wapieni, jak również obecność słabo krystalicznego kaolinitu jako głównego minerału obecnego w terra rossa.Archaeological excavation of Prachodna and Temnata Cave conducted in 80tis of XX century had multidisciplinary character. The results of excavation are described in papers and books (Kozłowski, Laville, Ginter, 1992, Pawlikowski 1992, 2010, Sirakov 1992). Presented publications is devoted process of weathering of limestone of mentioned caves and transformation of calcite into residuum called terra rossa. Mentioned investigation were conducted in field in 2014 and in lab. in 2015. Described phenomenon explain the formation of karstic forms as for example caves system of caves –Prachodna – Temnata. Results document various rate od chemical dissolution of various petrographic kinds of limestone as well as the presence of poorly crystalline kaolinite as mine secondary mineral present in terra rossa.wersja wydawnicz

Higher amounts of habitual physical activity changes the relationship between hot flashes and subclinical cardiovascular disease risk

The menopausal transition is associated with increased risk for cardiovascular disease (CVD). Hot flashes (HF), a cardinal symptom of menopause, have been associated with increased CVD risk, particularly in perimenopausal women. Flow- mediated dilation (FMD) is an indicator of endothelial function and a sub-clinical CVD risk factor. Lower FMD has been associated with more HF. As moderate to vigorous physical activity (MVPA) is recognized to reduce CVD risk, our goal was to determine whether higher levels of MVPA change the relationship be-tween HF and FMD in perimenopausal women. Healthy perimenopausal women had HF measured objectively using sternal skin conductance for 24 h. MVPA was determined using 7 days of actigraphy. Endothelial function was measured via brachial artery FMD on the non-dominant arm. Pearson correlations and multiple regression analyses were used to evaluate relationships between variables. Simple slopes analysis was performed to understand how MVPA moderates the relationship between HF and FMD. Lower FMD tended to correlate with a higher objective HF rate, and this relationship was stronger for HF measured during waking hours. Controlling for age and BMI, HF and the interaction between HF and MVPA were significant predictors of FMD. Simple slope analysis showed a significant HF effect on FMD with lower (−1SD) MVPA, whereas there was no significant relationship between HF and FMD with higher (+1SD) MVPA. These results suggest that MVPA moderates the relationship between FMD and objective HFs in perimenopausal wome
