Reactions of m-Terphenyl-Stabilized Germylene and Stannylene with Water and Methanol: Oxidative Addition versus Arene Elimination and Different React…
2015
Reactions of the divalent germylene Ge(ArMe6)2 (ArMe6 = C6H3-2,6-{C6H2-2,4,6-(CH3)3}2) with water or methanol gave the Ge(IV) insertion product (ArMe6)2Ge(H)OH (1) or (ArMe6)2Ge(H)OMe (2), respectively. In contrast, its stannylene congener Sn(ArMe6)2 reacted with water or methanol to produce the Sn(II) species {ArMe6Sn(μ-OH)}2 (3) or {ArMe6Sn(μ-OMe)}2 (4), respectively, with elimination of ArMe6H. Compounds 1–4 were characterized by IR and NMR spectroscopy as well as by X-ray crystallography. Density functional theory calculations yielded mechanistic insight into the formation of (ArMe6)2Ge(H)OH and {ArMe6Sn(μ-OH)}2. The insertion of an m-terphenyl-stabilized germylene into the O–H bond was…
Influence of harvesting time on composition of the essential oil of Thymus capitatus (L.) Hoffmanns. & Link. growing wild in northern Sicily and its …

One of the main factors affecting historical art crafts material is the biodeterioration performed by bacteria and fungi, in archives, museums or private collections. Several microorganisms cause degradation to the natural organic material such as fibers, woods, and dyes as well as to stone objects. These alterations produce deterioration of physical, chemical, mechanical and esthetic properties. Consequently, in this publication, we report the high antibacterial and antifungal activities of wild thyme essential oil, oil that can be used as an alternative natural tool in the fight against microorganisms affecting historical art crafts.Essential oil of the Thymus capitatus growing wild in no…
Emotions and Activity Recognition System Using Wearable Device Sensors
2021
Nowadays machines have become extremely smart, there are a lot of existing services that seemed to be unexpectable and futuristic decades or even a few years ago. However, artificial intelligence is still far from human intelligence, machines do not have feelings, consciousness, and intuition. How can we help machines to learn about human feelings and understand their needs better? People take their devices wherever they go, what can devices tell us about their owners? Personal preferences and needs are dependent on emotional and situational contexts. Therefore, emotional and activity aware gadgets would be more intuitive and provide more appropriate information to users. Contemporary weara…

Syväoja, Heidi. 2010. Effects of exercise intensity on recovery of autonomic nervous system immediately after exercise and during sleep, and on subjective and objective sleep quality. Master´s thesis in Exercise Physiology. Department of Biology of Physical Activity. University of Jyväskylä, 90. The exercise can be considered as a one form of stress, because it induces marked changes in the autonomic regulation of heart rate (HR). During acute exercise, parasympathetic activity decreases and sympathetic activity increases. Parasympathetic activity declines a lot or even disappears, when the exercise intensity is high. After acute exercise cessation, fast changes occur in the cardiac functio…
Parenthood and changes in physical activity from early adulthood to mid‐life among Finnish adults
2022
This study examined longitudinal associations between parenthood-related factors and physical activity from young adulthood to midlife over a 19-year follow-up period. Participants (n=761) at the ongoing Cardiovascular Risk in Young Finns Study responded to a self-report questionnaire in their adulthood (in 1992, 2001, 2007 and 2011). Participants were classified as meeting or not meeting an aerobic physical activity recommendation. Parenthood related factors included the age of having their first child, as well as the number and age of the children. Analyses of Generalized Estimation Equations were performed and adjusted for several demographic and health-related covariates. Both mothers a…

Naukowe dziedzictwo Heleny Radlińskiej. Pedagogika społeczna – nauka praktyczna
2018
Niniejszy artykuł stanowi efekt badania tekstów źródłowych Heleny Radlińskiej. Prezentuje naukowe dziedzictwo twórczyni polskiej pedagogiki społecznej. Dyscyplina ta jest jedną z nauk praktycznych. Opiera się na ścisłych związkach teorii z praktyką. Ontologiczny status polskiej pedagogiki społecznej zakłada jej praktyczność i kooperatywizm oraz holizm w rozpatrywaniu zjawisk i procesów społecznych. Teoretyczny dorobek tej nauki jest użyteczny w budowaniu metodycznych modeli działalności praktycznej.
Wybrane zagadnienia badań historycznych w polu polskiej pedagogiki społecznej: historia działalności społecznej
2020
Artykuł podejmuje zagadnienie badań historycznych, których przedmiotem jest działalność społeczna. Badania te wpisują się w pole naukowej aktywności polskiej pedagogiki społecznej, której twórczynią była Helena Radlińska. Badaczka ta opracowała metodę badań historycznych dla pedagogów społecznych. W oparciu o to podejście metodologiczne warto współcześnie podejmować kolejne badania historyczne w polu pedagogiki społecznej. Ich efekty będą służyły przywracaniu prawdy o przeszłości działalności społecznej i o jej przedstawicielach, ich naukowym i praktycznym dorobku. Z drugiej strony efekty tych badań będą stanowiły drogowskaz dla poszukujących nowych rozwiązań dla praktyki działalności społe…
The activity and pedagogical vievs of women at the turn the 19 th and 20 th centuries - historical experiences for the contemoprary times
2018
Although women have contributed to the development of science from the earliest times, their participation has not always been noticed. The breakthrough in the career path of women was World War I, in the consequence of which women gained the possibility of studying at universities and pursuing the academic activity. The presented article is an attempt at bringing to light the memory of the women-pioneers and their scientific acdvity in the field of Polish pedagogy at the turn of the 19th and 20th centuries.
