Recycling of solar photovoltaic panels
Šperlich, Antonín
2023 - Czech
Long-term trends show an increasing installed capacity of solar photovoltaic power plants. However, this is also associated with a large production of discarded panels. It is estimated that by 2050 there will be between 60 and 80 million tonnes of waste panels worldwide. Such large amounts of waste can be an \ninteresting source of valuable materials, but also need to be recycled for environmental reasons. The aim of this paper is to describe the possibilities of recycling panels and using them to build a real recycling line. Dlouhodobé trendy ukazují zvyšující se instalovanou kapacitu solárních fotovoltaických elektráren. S tím je však také spojena velká produkce vyřazených panelů. Odhadované množství odpadních panelů se předpokládá mezi 60 a 80 miliony tun celosvětově okolo roku 2050. Takto velké objemy odpadů mohou tvořit zajímavý zdroj cenných látek, ale také nutnost recyklace kvůli životnímu prostředí. Příspěvek má za cíl popsat možnosti recyklace panelů a jejich využití ke stavbě reálné recyklační linky.

Analytical Derivatization for Identification of Electrochemical Oxidation Products of Fentanyls
Barták, P.; Skopalová, J.; Jerga, R.; Štolbová, D.; Navrátil, Tomáš; Langmaier, Jan
2023 - Czech
Analytical derivatization and GC-MS analysis were employed for the identification of main\nproducts from the electrochemical oxidation of fentanyl derivatives. Chemical derivatization\nprovides proof of the chemical reactivity of functional groups in oxidation products and serves\nfor the chemical conversion of target compounds into the second series of derivatives to confirm\nthe identification of particular products. Using the direct GC-MS analysis of oxidation products,\nderivatization of aldehydes with cysteamine and derivatization of amides by acidic hydrolysis\nand subsequent reaction with ethylchloroformiate, phenylacetaldehyde, and Nphenylpropanamide\nwere unambigously identified as oxidation products from fentanyl,\nthiophen-2-ylacetaldehyde, and N-phenylpropanamide from sufentanil, and\nphenylacetaldehyde and 2-furanilid from furanylfentanyl. Analytická derivatizace a plynová chromatografie s hmotnostní spektrometrií se osvědčily jako\nvhodné nástroje pro identifikaci oxidačních produktů a řešení reakčního mechanismu\nelektrochemické oxidace fentanylů a dalších opioidů. Provedené experimenty potvrdily\npřítomnost fenylacetaldehydu a N-fenylpropanamidu v roztoku po elektrochemické oxidaci\nfentanylu. V případě sufentanilu byl jako odpovídající aldehydický produkt prokázán thiofen-\n2-ylacetaldehyd a v případě furanylfentanylu byl jako amidický produkt prokázán zcela\nanalogicky 2-furanilid.

The report summarizes the results of a comprehensive survey of the fish population of the Lipno reservoir in 2023. The goal of the ichthyological survey of the lake was to map the state and development of the fish population, with an emphasis on estimating the abundance and biomass of individual fish species, on estimating the risks of further development of the fish community and recommending further management of the reservoir. Zpráva shrnuje výsledky komplexního průzkumu rybí obsádky nádrže Lipno v roce 2023. Cílem ichtyologického průzkumu jezera bylo zmapování stavu a vývoje rybí obsádky zejména s důrazem na odhad početnosti a biomasy jednotlivých druhů ryb, na odhad rizik dalšího vývoje rybího společenstva a doporučení dalšího obhospodařování nádrže.

Supporting grassland biodiversity through small-scale fallows

The main goal of the methodology presented here is to propose a system of recommendations for applying fallow in nature conservation based on our experiments. Due to the independence of agricultural land outside specially protected areas with direct payments from the Ministry of Agriculture, it is currently important to apply the methodology, especially in large protected areas where the primary objective is to preserve natural and cultural heritage. Annual and perennial fallows, i.e. biotopes adapted toregular soil disturbance, offer suitable habitats for a number of now-threatened plant and animal species. This is a technically and economically easy solution, but it is challenging to select a suitable location to achieve maximum efficiency. Ploughing must not be used in species-rich grasslands which would lead to ruderalization and degradation of the native vegetation. Furthermore, it must not be carried out on land at risk of erosion. Linear grassland margins, which have been ploughed in the past, recently grassed fields, fallows, and field margins should be selected for fallow management. Nearby populations of invasive plant species can be a problem. Our recommendations for the use of fallow management relate primarily to land in lowland and upland areas with a lower soil nutrient supply. Hlavním cílem předkládané metodiky je na základě experimentů s úhorovým managementem navrhnout systém doporučení pro aplikaci maloplošné orby v ochraně přírody. Vzhledem k provázanosti zemědělské půdy mimo zvláště chráněná území s přímými platbami Ministerstva zemědělství (MZe) je v současné době důležité uplatnění metodiky zejména ve velkoplošných chráněných územích, kde je záchrana přírodního a kulturního dědictví primárním cílem. Jednoleté i víceleté úhory, tj. biotopy adaptované na pravidelné narušování povrchu půdy nabízejí vhodná stanoviště pro řadu dnes ohrožených druhů rostlin i živočichů. Jedná se o technicky i ekonomicky snadné řešení, pro maximální efektivitu je však obtížné zvolení vhodného stanoviště. Orba nesmí být použita v druhově bohatých travních porostech, kde by došlo k ruderalizaci a degradaci původní vegetace. Dále nesmí být prováděna u erozně ohrožených pozemků. Vybírány by měly být liniové okraje travních porostů, které byly v minulosti orané, tj. nedávno zatravněná pole, úhory, okraje polí. Problémem mohou být blízké populace invazních druhů rostlin. Naše doporučení k využití úhorového hospodaření se primárně vztahují na pozemky s nižší zásobou živin v půdě v nížinách a pahorkatinách.
