Waste as a source of business opportunities for circular economy and bioeconomy
MAROUŠKOVÁ, Anna
2024 - English This dissertation thesis underlines the promising potential of biowaste processing using Black Soldier Fly (BSF) larvae with the subsequent production of value-added products such as feed components, fertilizers, cosmetics, etc. The concept is gaining global popularity, although legislative challenges initially hindered EU companies, resulting in delays in the placement of BSF products on the market. Nevertheless, EU enterprises, leveraging the time afforded by evolving legislation, emerged with cutting-edge technologies, positioning them to produce high-quality protein for animal feed and other value-added products. The study reveals a significant correlation between business development and scientific achievements in the field of BSF rearing in the EU and EFTA Member states. Another finding of this study was that countries with established Bioeconomy strategies at the national level show higher numbers of publications and established companies in the field of BSF rearing compared to those with Bioeconomy strategies under development or other bioeconomy-related policies. However, the biggest finding of this study is the results of the BSF meal, soybean meal and fish meal competitiveness analysis for the first time conducted in the Czech Republic. The comprehensive analysis showed that BSF meal has the potential to compete with products like soybean meal and fish meal despite its current market price is still a major drawback. The main benefits of the BSF meal are well-balanced nutritional properties and demonstrated positive ecological impact. It was also discovered that under the current conditions, the key bottlenecks are insufficient BSF products supply and the overly strict EU legislation which causes challenges in the price competitiveness. However, based on the review accompanied by the competitiveness analysis results and taking into account political trends, it can be concluded that industrial insect rearing represents a significant commercial potential.

Počítačové modelování pohybu zemědělské techniky po pozemku
FILIP, Martin
2024 - Czech Tato disertační práce se zabývá problematikou optimalizace počtu odvozních souprav a nakladačů při manipulaci, svozu a přepravě balíků píce, nebo slámy z pozemku na místo skladování tak, aby bylo dosaženo co nejnižší spotřeby lidské práce. Automatizovanýrozhodovací proces umožňuje zvolit optimální počet odvozních souprav a nakladačů tak, aby nedocházelo ke zbytečným prostojům manipulačních prostředků při čekání na přepravní techniku, nebo naopak aby nevznikaly ztrátové časy odvozních souprav nedostatečnou kapacitou nakladačů. Základní funkcí optimalizačního programu je zpracování obrazového snímku reálného pozemku, detekování jeho hranic a na základě odhadů výnosu píce nebo slámy odhadnout přibližné rozmístění velikostně předem definovaných balíků a určení centroidů, tedy míst, kde by měla být přistavena odvozní souprava při nakládání Centroid je současně místo, ze kterého jsou nejkratší pojezdové vzdálenosti pro nakladač. K centroidům jsou postupně přiřazovány balíky s nejnižší vzdáleností až do naplnění skupiny. Jedná se o stav, kdy počet balíků ve skupině odpovídá přepravní kapacitě odvozního prostředku. Další funkcí optimalizačního algoritmu je naplánování pojezdových tras v centroidu, a na základě vstupní hodnoty průměrné rychlosti nakladače, je vypočítaný potřebný čas pro pojezd tohoto stroje. K celkovému pracovnímu času nakladače je přičten i čas potřebný na jízdu z prostoru uskladnění stroje k pozemku, a také čas potřebný pro pojezd z místa vstupu na pracovní plochu k centroidu, i doba jízdy od zpracovaného centroidu k dalším centroidům, včetně doby pojezdu ze sklizených ploch zpět na místo, kde bude nakladač odstaven. K pojezdu nakladače je dále přičtena hodnota potřebného času zdvihu všech balíků v centroidech a jejich uložení na odvozní prostředek a doba prostojů manipulátoru, čímž je zjištěn celkový čas práce nakladače. Pracovní čas odvozních souprav je vypočten z dálky trasy (násobené průměrnou rychlostí těchto strojů) z místa uskladnění strojů k centroidu, doby nakládání a času potřebného na pojezd k místu skladování balíků, včetně doby potřebné na složení balíků z odvozní soupravy. Čas nakladačů a odvozních souprav je vyhodnocován souběžně, v synchronizaci, a je rozhodováno, zda dochází ke ztrátovým časům, které jsou postupně připočítávány pracovním časům. Optimalizační program postupně počítá různé varianty pro (n) nakladačů, (n) odvozních souprav, vyhodnocuje, která varianta spotřebuje nejméně času a je tedy optimální z pohledu nejnižší spotřeby času. This dissertation deals with the problem of optimizing the number of hauling trailers and loaders in the handling, collection and transport of bales of fodder or straw from the land to the storage site in order to achieve the lowest possible consumption of human labour. The automated decision-making process allows the optimum number of removal trailers and loaders to be selected s that there is no unnecessary downtime for the handling equipment while waiting for the transport equipment or, conversely, no lost time for the removal trailers due to insufficient loader capacity. The basic function of the optimization program is to process a Google Maps image of a real plot of land, detect its boundaries and, on the basis of estimates of forage or straw yields, estimate the approximate distribution of predefined bale sizes and determine the centroids, i.e. the locations where the hauler should be positioned when loading.The centroid is also the point from which the shortest travel distances for the loader are obtained. The centroids are assigned successively to the packages with the lowest distance until the group is full. This is the condition where the number of bales in the group corresponds to the transport capacity of the conveyor. Another function of the optimization algorithm is to schedule the travel routes in the centroid and based on the input value of the average speed of the loader, the time required for the travel of this machine is calculated. To the total working time of the loader is added the time required for driving from the storage area of the machine to the plot, as well as the time required for driving from the point of entry to the working area to the centroid, and the driving time from the processed centroid to the other centroids, including the driving time from the harvested areas back to the place where the loader will be parked. In addition, the value of the time required to lift all bales in the centroids and place them on the conveyor and the downtime of the manipulator are added to the loader's travel time to obtain the loader's total time. The working time of the removal trains is calculated from the distance of the route (multiplied by the average speed of these machines) from the storage location of the machines to the centroid, the loading time and the time required to travel to the storage location of the bales, including the time required to remove the bales from the removal trains. The time of the loaders and the removal trains is evaluated simultaneously, in synchronisation, and it is calculated whether there are any lost times, which are added successively to the working times. The optimization program sequentially calculates the different variants for (n) loaders, (n) transfer sets, evaluates which variant consumes the least time and is therefore optimal in terms of the lowest time consumption.

Využití genetických algoritmů k optimalizaci činnosti zemědělských strojů v systémech precizního zemědělství
BUMBÁLEK, Roman
2024 - Czech Metaheuristické metody, inspirované fyzikálními, biologickými, chemickými, séman-tickými i sociálními jevy, jsou aplikovány pro optimalizaci úloh s rozsáhlou množinou možných řešení v širokém spektru oborů včetně zemědělství, přičemž významnou část tvoří evoluční výpočty, z nichž jsou pro potřeby precizního zemědělství využívány především genetické algoritmy. Tato práce se zabývá jejich implementací v rámci pro-blematiky plánování tras pojezdu zemědělské techniky s cílem snížení délky trajekto-rie pohybu na souvratích i ve vnitřní části pozemku. Vytvořený algoritmus se skládá z několika částí, kdy nejprve dochází k výpočtu souřadnic dílčích tras a následně apli-kací genetických algoritmů k optimalizaci otáčení souprav na souvratích vhodnou kombinací jejich průjezdů s ohledem na vstupní parametry zahrnující poloměr otáčení a záběr nástroje. Kvalitu získaných výsledků ovlivňuje mnoho parametrů použitého genetického algoritmu, jako je velikost populace, počet generací či zvolený typ se-lekce, kdy se zvyšujícím se množstvím chromozomů v populaci i generací dochází k vygenerování lepších řešení, umožňujících zkrácení vzdálenosti pojezdu při otáčení na souvratích o více než 37 %, což může přímo vést k úsporám pracovního času, po-honných hmot a nižšímu zhutnění půdy. Metaheuristic methods, inspired by physical, biological, chemical, semantic and social phenomena, are used to optimise problems with a large number of possible solutions in a wide range of fields, including agriculture, with a significant part of evolutionary computation, of which genetic algorithms are mainly used for precision agriculture. This paper deals with their implementation in the context of the problem of planning the routes of agricultural machines with the aim of reducing the length of the trajectory of movement both on the headlands and in the inner part of the plot. The developed algorithm consists of several parts, where first the coordinates of the partial routes are calculated and then genetic algorithms are applied to optimise the rotation of the im-plements on the headlands through a suitable combination of their passes with respect to the input parameters, including the turning radius and the tool sweep. The quality of the results obtained is influenced by many factors, such as the size of the population, the number of generations or the type of selection chosen, with better solutions being generated as the number of chromosomes in the population and generations increases, allowing a reduction of more than 37 % in the distance travelled when turning on he-adlands, which can directly translate into savings in working time, fuel and reduced soil compaction.

Anthropogenic impact on early-life stages of rheophilic fish
BARTOŇ, Daniel
2024 - English This study focuses on the problems faced by the early-life stages of fish living in a river influenced by reservoirs and suggests possible solutions to enhance recruitment. The model fish for the study is the asp (Leuciscus aspius), known for its significant and protected population in the Želivka Reservoir, from where it migrates for reproduction to the tributary of Želivka River. The asp migrates upstream in spring to spawn in shallow, fast-flowing waters. At a research site, the adult population of asp is monitored using passive telemetry. Fish are caught, tagged, and released back into the reservoir. The asp population faces threats due to hydropeaking and river fragmentation. Hydropeaking causes egg detachment from the pebbles and their sedimentation in the reservoir. The study suggests that water should not exceed a velocity of 0.7 m×s-1 at the spawning ground. Periodically increasing discharge also shifts spawning fish outside their preferred spawning site, causing disruption of spawning and potentially lowering recruitment. A flowdeflector was built to protect newly spawned eggs from hydropeaking. However, there are additional threats to the asp recruitment process such as egg consumption by non-indigenous fish like common bream (Abramis brama). Water flow conditions are crucial for the conservation of rheophilic fish, as these fish, aside from habitat loss and modification, also face newly interacting generalist fish species moving from lentic to lotic sections of the system. Fish communities can be affected by reservoir construction far upstream, and these anthropogenic habitat alterations have severe negative impacts on threatened rheophilic fish recruitment.

A novel structurally characterized haloacid dehalogenase superfamily phosphatase from Thermococcus thioreducens with diverse substrate specificity
HAVLÍČKOVÁ, Petra
2024 - English This RNDr. thesis is focused on complex studies of a haloacid dehalogenase superfamily phosphatase member with an unknown substrate specificity, isolated from a hyperthermofilic archeon Thermococcus thioreducens. The HAD phosphatase, internally named as Tt82, was isolated, expressed and purified using standard techniques and the crystal structure was solved by X-ray crystallography method. The refined crystal structure displayed characteristic HAD superfamily elements, such as the HAD canonical fold with the HAD signature motifs in the active site. Further, possible substrates for the enzyme were proposed and examined by computational docking in the active site of the HAD phosphatase. The results of the docking studies served as a basis for an experimental measurement of Tt82 enzymatic activity against selected substrates at two different temperatures. HAD phosphatase Tt82 is a promising target for the biotechnological field, mainly for its wide substrate specificity and higher temperature optima.

Functional Ultrastructure of Hymenopteran Stingers: Devastating Spear or Delicate Syringe
ČERNÝ, Jan
2024 - English In this study, we tested the hypothesis that a micro-serrated edge on the honey bee Apis mellifera stinger tip serves as a tool for more intensive crushing of cell membranes in the victim's tissues. This could have mechanical consequences as well as initiate metabolic pathways linked to cell membrane breakdown (e.g., production of biogenic amines). Accordingly, we found that hymenopteran species that use their stingers as an offensive or defensive weapon to do as much damage to the victim's body as possible had this cuticular microstructure. In parasitic hymenopterans, on the other hand, this structure was missing, as stingers are solely used to delicately transport venom to the victim's body in order to do little mechanical harm. We also demonstrated that the stinger lancets of the honey bee A. mellifera are living organs with sensilla innervated by sensory neurons and containing other essential tissues, rather than mere cuticular structures.
