Supported Liquid Membranes for Hollow-Fibre Based Microextraction and Voltammetric Determination of Neuroblastoma Biomarkers
Josypčuk, Bohdan; Barek, J.; Josypčuk, Oksana
2018 - English
A new type of tubular detector (TD+AuxE) was proposed, fabricated, tested and compared\nwith a typical silver amalgam tubular detector developed earlier. Non-stop-flow differential\npulse voltammetric anodic stripping method (AS-DPV) and amperometric method in a\nglucose oxidase biosensor arrangement were tested. Both detectors were applied for AS-DPV\nmeasurements in flow systems for the first time. The proposed combination of tubular\ndetector with auxiliary electrode provides a much greater current response than the classic\narrangement with three individual electrodes. All relevant parameters (potentials of\naccumulation or detection, flow rate, analyte concentrations, shielding sleeve length, etc.)\nwere optimized for the developed TD+AuxE. Keywords: Flow analysis; Amperometry; Voltammetry Available at various institutes of the ASCR

Tourist interest in illicit zone of ice caves
Nováková, Eva; Kuda, František; Kubalíková, Lucie
2018 - English
Ledové sluje (Ice Caves) in the Podyjí National Park represents one of the most spectacular sites within the area. It consists of the large boulder field and several pseudokarst caverns on the north-western slope of the ridge that are very important from the ecological and geomorphological point of view. The access to the site is restricted for the visitors of National Park as there exists a risk of damage and disturbance of these unique phenomena; tourist can use the marked paths leading around the site, they can reach the top part of the ridge.\nCurrently, there are only several persons who have legal access to the site (employees of the National Park Administration and other researches with the permission issued by NP Administration). However, the installed sensor that counts the passages proved that the site is visited more frequently than it should be. The number of people who visit this site (situated within the first zone of National Park where there is no marked path and so the access is forbidden by decree) is quite alarming. Based on these findings, some proposals for the solution of this unfavourable situation are proposed and other possibilities how to avoid this undesirable phenomenon are discussed.\n Keywords: Podyji National Park; restricted area; passages monitoring Available in a digital repository NRGL

„Jak milo bylo v sednici, když se smrklo!“ Černá hodinka a její reflexe v české literatuře 19. století
Piorecká, Kateřina
2018 - Czech
Černou hodinkou se v 19. století rozumělo přestávku v práci při západu slunce před tím, než se vyplatí rozsvítit, přeneseně se pak stalo obecným pojmenováním doby stmívání a po setmění, kdy se lidé sesednou a vyprávějí. Tento fenomén byl původně vázán na zimní sezónní práce, především přástky. Světelné podmínky dovolily přežívání orální tradice, jež v průběhu 19. století zajímala folkloristy i etnografy. V postupující proměně tradičních struktur v občanskou společnost se společně s industrializací, jež převálcovala nejen tradici přástek a draček, ale zpřetrhala cyklický čas a položila důraz na linearitu veškerého dění, je třeba sledovat i proces literalizace. Čeští spisovatelé orální útvar pověsti, pohádky či humorky vtiskli do prestižních literárních žánrů, jakými byly balada, idyla, selanka či mravoučná povídka. Na příkladu krátkých próz Boženy Němcové a její Babičky příspěvek dokládá, že jejím spisovatelským úsilím bylo orálně tradované texty pozdvihnout prostřednictvím prestižních žánrů do literárního kánonu. In the 19th century the term “the black hour” meant the break in work at sunset, before it was worth lighting the lamps. Figuratively it became the general term for the period of dusk and after nightfall, when people used to sit together and talk. This phenomenon was originally connected with winter seasonal work, in particular flas-spinning session. The lighting conditions allowed oral traditions to survive, which in the course of the 19th century came to interest students of folklore and ethnographers. However, the process of industrialisation not only put an end to the tradition of people sitting together and talking while spinning or plucking feathers, but also severed cyclical time and placed the emphasis on the linearity of everything that happened. As part of the progressive transformation of traditional structures in civil society the process of literalisation needs to be observed as well. Czech writers imprinted oral forms such as legends, fairy-tales, or humorous stories into prestigious literary genres such as ballads, idylls, or short stories whit a moral. Taking the example of Božena Němcová’s shor proses and her novel Babička (Grandmother), the article shows that as a writer she tried to raise texts that had been passed down orally into the literary canon by the use of prestigious genres.

Asymmetry of the response probability density of a system with parametric random noises
Náprstek, Jiří; Fischer, Cyril
2018 - English
Recording of time variable processes is accompanied by various internal disturbing effects as a rule. They influence parameters of the measuring facility, transducer-device transmission, etc. These parasitic processes are usually of the random character and, consequently, they exercise as parametric noises. Moreover, the input signal mostly consists of a useful signal which can be taken as composed from deterministic and random additive part. Various combinations of these noises are the origin of random and also systematic measuring errors which can have under certain circumstances a cumulative character, deteriorate the output signal quality and can lead finally to the stochastic stability loss. These effects can be theoretically described using differential systems with stochastic coefficients and stochastic right hand side considering all input and output processes to be of the Markov type. Keywords: random vibration; signal reconstruction; parametric noise; response asymmetry Available at various institutes of the ASCR
