Canoe slalom is an Olympic discipline conducted on a whitewater course, where athletes navigate through sequence of upstream and downstream gates. Two types boats are used in this sport: canoe (C) kayak (K). In the events, use single-bladed paddle adopt kneeling position with legs bent secured under body, contrasting seated double-bladed technique events. At international level, six individual events contested: women’s (WK1), men’s (MK1), (WC1), (MC1), cross (WX1), (MX1) (1). From Tokyo 2020...
The widespread use of synthetic polymers since the mid-twentieth century has led to significant environmental pollution from microplastics (MPs). These MPs, which persist in ecosystems, can interact with various pollutants, including pesticides such as tebuconazole (TEB). subject paper investigates sorption behaviour TEB on different types MPs (polystyrene, polypropylene, and polyamide-6), focusing kinetics isotherms these interactions. role metal cations (Al, Cd, Cu, Pb, Zn) influencing is...
Electrospray ionization mass spectrometry (ESI‐MS) is used to probe the complex formation between tebuconazole (1) and copper(II) salts, which both are commonly fungicides in agriculture. Experiments with model solutions containing 1 CuCl 2 reveal initial of species [(1)CuCl] + [(1) CuCl] undergo reduction corresponding copper(I) ions [(1)Cu] Cu] under more drastic conditions ESI source. In additional experiments, copper/tebuconazole complexes were also detected samples made from soil...
Abstract The Cd and Pb complexes with oxalic (OA) citric acid (CA) were detected in model soil solutions using cyclic stripping voltammetry. A mixed complex consisting of Cd, Pb, OA was found; its peak potential varied from −582.0 to −542.5 mV (vs. Ag/AgCl/KCl(3 mol L −1 )). For formation, the presence PbOH + species 2+ solution necessary. Only ‘simple’ CA found solution. existence all investigated metal is confined neutral pH range. also real solutions.
Background: Home-based video exercise programmes might be a suitable alternative to traditional physi¬cal activity in older adults preserve muscle health. The aim of this systematic review and meta-analysis was examine the effects home-based on physical fitness adults. Methods: A robust variance estimation with meta-regression were carried out according recommendations criteria outlined Preferred Reporting Items for Systematic Reviews Meta-Analyses (PRISMA) statement. Results: Thirteen...
Tebuconazole (Teb) as a systemic fungicide amounts potential risk for environment even in very low concentrations. The voltammetric behavior of Teb was investigated using the newly developed mercury meniscus-modified copper solid amalgam electrode (inner diameter 1.5 mm). Differential pulse voltammetry (DPV) and cyclic (CV) were utilized these purposes. reaction mechanism CV elimination with linear scan (EVLS). optimum conditions DPV determination found Britton-Robinson buffer/methanol (1:1,...
The knowledge of thermodynamic balances among metal species in environmental matrixes can help the understanding processes related to stress plants and design suitable phytoremediation strategy. In these processes, lowmolecular- weight organic acids (LMWOAs) play a very important role, therefore determination metals with LMWOAs is current research interest. Electrochemical techniques available for trace analysis ions are speciation studies including computation stability constants...
Background: Maintaining healthy brain function during ageing is of great importance, especially for the self-sufficiency older adults. The main aim this study was to determine effects dance and martial arts on exerkines Brain Derived Neurotrophic Factor (BDNF) irisin blood serum levels. Methods: This randomized controlled trial examined Brain-Derived levels, as well cognitive function, mood, physical measures in Seventy-seven independently living adults (mean age 70.3± 3.8 years) were into...
Abstract In the soil solutions obtained in situ with suction cups from soils (Cambisol and Fluvisol) of pot experiment Salix smithiana Smith, Lolium perenne L. Thlaspi caerulescens J. & C. Presl heavy metals species (Cd, Pb Cu) were assayed by differential pulse anodic stripping voltammetry diffusive gradient thin films. Prediction accumulation performed best at free metal ion concentrations unchanged pH (in 10−3 mol L−1 NaClO4 base electrolyte). The speciation provided according to...
In experiments with willow planted in cadmium- or lead-contaminated Knopp nutrient solutions, the ability of and chelex gel diffusive gradient a thin film (DGT) unit to absorb these elements was observed compared. A method compare accumulated amount metals by sorbed metal onto DGT designed. The accumulated/sorbed recalculated same units (μg cm−2 day−1). study Cd(Pb) dynamic uptake showed an exponential decrease content exposure solution. solution less than did matrix. soil/water system more...
The transport of cadmium and copper ions across the artificially prepared model phospholipid (PL) membranes on polycarbonate supports was studied in present manuscript. processes were investigated presence selected low molecular weight organic acids (LMWOAs) (malic acid (MA), oxalic (OA) citric (CA)), which substantially affect conditions rhizosphere. It found that influenced by presence/absence ionophores calcimycin value pH. Electrochemical impedance spectroscopy (EIS) used to monitor...
A young speckled alder (Alnus incana [L.] Moench) stand was planted on a tract clear-felled due to air pollution and located summit plateau of the Jizerské hory Mts. (Central Europe, Czech Republic) at an altitude 950 m a.s.l. The aim experiment test suitability Alnus form preparatory stands covering site thus enabling reintroduction more sensitive target species. potential respond slow-release fertilizing tested as well. control treatment showed sufficient growth dynamics, nevertheless,...
