We report an experimental study of guided transmission low-energy $(200--350\phantom{\rule{0.3em}{0ex}}\mathrm{eV})$ electrons through highly ordered ${\mathrm{Al}}_{2}{\mathrm{O}}_{3}$ nanocapillaries with large aspect ratio ($140\phantom{\rule{0.3em}{0ex}}\mathrm{nm}$ diameter and $15\phantom{\rule{0.3em}{0ex}}\mathrm{\ensuremath{\mu}}\mathrm{m}$ length). The nanochannel array was prepared using self-ordering phenomena during a two-step anodization process high-purity aluminum foil....
Abstract. During a three-year field campaign of measuring waterfall generated ions, we monitored five different waterfalls in the Austrian Alps. Most measurements were performed at Krimml (Salzburg, Austria), which is biggest Europe, and Gartl (Mölltal, Austria). We characterized spatial, time size distributions waterfall-generated ions under influence surrounding topography. The smallest with boundary diameters 0.9, 1.5 2 nm, measured cylindrical air ion detector (CDI-06), while sizes from...
The specific microclimate of alpine waterfalls with high levels ionized water aerosols has been suggested to trigger beneficial immunological and psychological effects. In the present three-armed randomized controlled clinical study, we focused on effects (i) reagibility, (ii) physiological stress responses, (iii) stress-related parameters. People moderate (n = 65) spent an active sojourn daily hiking tours in National Park Hohe Tauern (Großkirchheim, Austria). Half group was exposed aerosol...
Three basil plant varieties (Ocimum basilicum var. Genovese, Ocimum × citriodorum, and purpurascens) were grown under moderate light (about 300 µmol photons m-2 s-1) in a glasshouse or growth chamber then either transferred to an open field (average daily dose: 29.2 kJ d-1) additionally exposed UV-B irradiation (29.16 d-1), reveal the variety-specific light-specific acclimation responses. Total antioxidant capacity (TAC), phenolic profile, ascorbate content, class III peroxidase (POD)...
Ionized water aerosols have been suggested to exert beneficial health effects on pediatric allergic asthma. Their effect was evaluated in a randomized controlled clinical trial as part of summer asthma camp.Asthmatic children (n = 54) spent 3 weeks an alpine camp; half the group exposed aerosol waterfall for 1 hour per day, whereas other same time at "control site". Immunological analysis, lung function testing, and fractional exhaled nitric oxide (FeNO) testing were performed during stay,...
Tomato (Solanum lycopersicum L.) is among the economically most important vegetables in Europe, valued for its bioactive properties due to significant contents of vitamins, carotenoids, and phenolic compounds. In this study, tomato cultivar Big Beef F1 was grown open field (OF) under polytunnels central Serbia during 3 years. Polytunnels were covered with two foils (both 57% reduced photosynthetic active radiation, PAR) differing UV-A UV-B transmittance. The aim our work determine influence...
We present a method for the estimation of annual radon concentration based on short-term (three months) measurements. The study involves results from two independent sets indoor measurements performed in 16 cities Republic Macedonia. first data set contains winter and obtained during National survey 2010 second, only measured 2013. Both pertain to same have been applying methodology ground floor dwellings. appeared be consistent dispersion was low. Linear regression analysis revealed high...
The application of energy-saving policies in buildings could lead to a decrease the air exchange rate dwellings, which consequently an increase indoor radon concentration and, therefore, resident exposure ionizing radiation. aim research presented this paper is investigate radiological residents due usage different granites commonly used Serbia as building material. From total 10 analysed granite samples, wide range and thoron exhalation rates were found: from <161 μBq m−2 s−1 5220 ± 200...
Low current measurements in atmospheric ion detection using a Gerdien condenser are subjected to numerous sources of error. Zeroing and testing units described this article, connected as modules type detector, enable some these errors be found eliminated. The zeroing unit provides digital compensation the zero drift with sample hold circuit 12-bit resolution. It overcomes difficulties related techniques used conductivity determination when accelerating potential or airflow rate zero. is...
Abstract The requirements about radon measurements in schools and public buildings included most of the national international legislations are generally restricted to all rooms located at ground floor basement, assuming soil beneath building as main source indoor radon. In order verify such an assumption for small having maximum two floors, a preliminary study was performed 50 15 municipalities Republic Srpska. Results this suggest that protocol requiring only may be considered adequate....
