ORIGINAL_ARTICLEThe aim of this study was to evaluate the possibilities of execution of the 60 second Bosco test of anaerobic power and capacity using the Emed system with mobile pedographic system Pedar in field conditions. Apart from evaluating the common parameters of maximal anaerobic power and anaerobic capacity of an individual using the above mentioned system, we also focused on differences in the variables of each limb. The system Emed with mobile pedographic facility Pedar is possible to be used for the diagnostics of anaerobic power and capacity evaluated by Bosco test in field conditions. We did not notice any statistically important difference in aerial and contact phase of the dominant and non-dominant limb during the 60 seconds of the test while observing the signs of domination of the limbs. Therefore there were not any signs of domination of the limbs.https://acc-ern.tul.cz/archiv/PDF/ACC_2017_1_01.pdf2017-06-3071410.15240/tul/004/2017-1-001Anaerobic power and capacityBosco testPressure distribution measurementIvaŠeflová1AUTHORSoňaJandová2AUTHORKristýnaMrázková3AUTHORLukášHůla4AUTHORJanHonců5AUTHORKamilaKlečková6AUTHOR

ORIGINAL_ARTICLEThis paper describes the trilateral transboundary project Prameny spojují/Quellen verbinden launched in 2016 under the coordination of the Technical University of Liberec. The aim of the project is a complex hydrochemical, hydrobiological, hydrological, geological and human geographical assessment of a set of about 40 springs in the region Liberec – Zittau through educational and research networking of the partner universities. This region has considerably humid climatic environment reflected in a high number of springs, whose mutual multidisciplinary assessment has been largely missing. Preliminary example results at the Ploučnice spring reveal a calcium-bicarbonate water originating from the Bohemian Cretaceous Basin, with slightly elevated spring values of Cd and autumn values of Pb in the sediment. The spring ecosystem is characterized by seminature montane mixed forest, with presence of freshwater shrimp in the spring water. The Ploučnice spring is one of the most abundant springs in Central Europe with a good water quality, which has promoted the use of this water for drinking purposes around 1900, and until the 1960’s for water energy in the nearby mills.https://acc-ern.tul.cz/archiv/PDF/ACC_2017_1_02.pdf2017-06-30152610.15240/tul/004/2017-1-002EducationEnvironmental sciencesSpringsChemistryBiologyTransboundary regionTomášVitvar1AUTHORMatthiasKändler2AUTHORJiříŠmída3AUTHORDanaKomínková4AUTHORRudincová KateřinaŽenková5AUTHOREmilDrápela6AUTHORKamilZágoršek7AUTHORLucieSoučková8AUTHORKateřinaBerchová9AUTHORMichalBílý10AUTHORHynekBöhm11AUTHOR

ORIGINAL_ARTICLECoal mining has had demonstrable negative impacts on the region and the landscape. In accordance with a growing number of inhabitants, the demand for energy consumption is constantly increasing. For the future, it is important to focus primarily on renewable energy resources, which will ensure the sustainable development of the environment and society. This contribution deals with the area in the Czech Republic that has had the greatest problems in this regard, namely North Bohemia (the Chomutov, Most, Teplice, and Ústí nad Labem districts). This is an area with significant anthropogenic activity, particularly due to the intensive mining of brown coal and in relation to the power industry. The Podkrušnohoří region has recently seen the partial suspension of mining limits at the Bílina Quarry, which is the reason why the regeneration of the region through reclamation and restoration will be needed. At the same time, this contribution contains a proposal for a possible change in the power industry, i.e. regarding the sources of renewable energy in the Podkrušnohoří region that could potentially be utilized after mining in individual quarries ends after 2050.https://acc-ern.tul.cz/archiv/PDF/ACC_2017_1_03.pdf2017-06-30273810.15240/tul/004/2017-1-003Sustainable developmentRenewable energy resourcesCoal miningNorth BohemiaJaroslavaVráblíková1AUTHORPetrVráblík2AUTHORMiroslavaBlažková3AUTHOREliškaWildová4AUTHOR

ORIGINAL_ARTICLEChitin which is located at outer surface of arthropods and some other organisms adsorbs quite a variety of possible environmental pollutants such as heavy-metal ions and –complexes and biomethylation products; thus biomonitoring is feasible without passing (and thus probably fractionating) analytes through metabolism. Isolated (from crab peeling) and grafted, chitin likewise acts as a sorbent, even in conditions which a living animal would not endure. Techniques originally developed in the author´s lab to maintain animal integrity throughout sampling protocols are now used for analytical workup omitting sample digestion. Hazardous or poorly accessible sites may be investigated using ROVs which deploy chitin samples to the site for the 10 min until adsorption is usually completed.https://acc-ern.tul.cz/archiv/PDF/ACC_2017_1_04.pdf2017-06-30405010.15240/tul/004/2017-1-004ChitinEnvironmental sampling by adsorptionBiopolymer solutionsAnalytical workup omitting sample digestionAddressing hazardous sites by purposely designed ROVsStefanFränzle1AUTHOR

ORIGINAL_ARTICLEThe simulation tool DynStar, created by Hochschule Zittau/Görlitz IPM department, was previously using only single-step methods to solve differential equations. This paper describes the development of a multiple step method to complement the others. The Introduction gives the reader a better idea why a multiple step method can be useful. The theory part is focused on the two-step Adams-Bashforth-Moulton method and how it is possible to make the formulas suitable for variable stepsize. Further, an algorithm is developed to solve the differential equations, using the ABM formulas and adjusting the stepsize according to the error between the prediction and the correction. This is described in the Implementation section. Finally, the performance of the ABM method is compared with RK4 and the Hanna method in the Results section.https://acc-ern.tul.cz/archiv/PDF/ACC_2017_1_05.pdf2017-06-30516110.15240/tul/004/2017-1-005Adams-Bashforth-MoultonMultistep methodVariable stepsizeNumerical solutionOrdinary differential equationInitial-value problemHanna methodAnPletinckx1AUTHORDanielFiß2AUTHORAlexanderKratzsch3AUTHOR
