Cilj rada je ispitivanje kvaliteta podzemnih voda tri izvorišta na teritoriji opštineLaktaši u naseljima Kriškovci, Maglajani i Laktaši, kao i uticaja prirodnih uslova iantropogenih dešavanja u okolini izvorišta na kvalitet ispitivanih podzemnih voda.Detaljno dizajnirana laboratorijska istraživanja i planiran eksperimentalni deo ovedisertacije predstavlja polaznu osnovu u rešavaju kompleksne problematike iz oblasti upravljanja kvalitetom voda za piće istražnog područja. Poseban doprinos nauci u oblasti zaštite voda predstavlja integrisan pristup u analizi selektovanih organskih, neorganskih i fizičko-hemijskih parametara podzemnih voda i definisanje osnovnih i specifičnih zavisnih varijabli hemometrijskom analizom podataka kao i kreiranje eksperimentalnih i laboratorijskih uslova za demanganizaciju vode kritičnih izvorišta. Ovaj sveobuhvatni pristup u skeniranju opštih i specifičnih varijabli i definisanje veza između elemenata, grupisanje na osnovu njihovih sličnosti ili razlika u specijalne klase prema karakterističnim fizičko-hemijskim svojstvima i sposobnosti ka kompleksiranju, ukazuje na način pojavljivanja promenljivih, njihovo poreklo u vodi i definiše uzroke njihove varijabilnosti (antropogeni - tačkasti ili difuzni, ili nativni, dominantno geološki). Svi analizirani in situ parametri zadovoljavaju kriterijum propisan važećim Pravilnikom o higijenskoj ispravnosti vode za piće (2003). Od 1632 merenja u laboratoriji (72 parametara), 26 merenja (1,59%) nisu zadovoljavala kriterijume propisane ovim Pravilnikom (15 merenja u vodi sa izvorišta Kriškovci (57,6%), 7 sa izvorišta Maglajani (26,9%) i 4 sa izvorišta Laktaši (15,4%)). Parametri koji odstupaju od kriterijuma datih Pravilnikom (2003) su mutnoća, nitriti, mangan, ulja i masti. Sa mikrobiološkog aspekta voda izvorišta u Laktašima je zdravstveno ispravna, dok je voda izvorišta u Kriškovcima u najlošijem stanju, na izvorištu u Maglajanima nisu detektovane bakterije indikatori fekalnog zagađenja, dok je voda reke Vrbas jako lošeg kvaliteta. U okviru ove doktorske disertacije ostvaren je značajan doprinos u otkrivanju i razumevanju međusobnih odnosa pojedinih elemenata i parametara u složenom sistemu kakav je voda posebno imajući u vidu analizu organskog i neorganskog kompleksiranja, što predstavlja značajan doprinos u ovom polju imajući u vidu ograničen broj literaturnih referenci. Iz rada se može doneti zaključak da se rezultatiispitivanih parametara na izvorištima menjaju u toku godine, da je potrebno izvršiti dodatna geološka ispitivanja da bi se sa sigurnošću utvrdila veza između vode reke Vrbas i vode izvorišta, da na izvorište u Kriškovcima ima uticaj biološko pođubravanje zemljišta i otpadne vode okolnog naselja, dok za druga dva izvorišta nije dokazana sumnja da dešavanja na površini iznad izvorišta utiču na samo izvorište i da padavine nemaju značajan uticaj na iste. Data ispitivanja su bazirana na osnovnim zahtevima okvirne direktive o vodamna (EU Water Framework Directive (WFD)) na prvom mestu izboru prioritetnih i ostalih supstanci od interesa u cilju praćenja i definisanja indikatora pritisaka i uticaja na vodna tela. Dobijeni podaci će poslužiti za razvoj strategija i planova kontrole i sprečavanja zagađenja, definisanje programa za praćenje kvaliteta podzemnih voda i vode za piće, upravljanja rečnim slivom, dostupnost informacijama u cilju poboljšanjakvaliteta vode za piće.The aim of this paper is to examine the quality of groundwater of three springs on theterritory of the municipality of Laktaši in the Kriškovci, Maglajani and Laktaši settlements, as well as the influence of natural conditions and anthropogenic activities in the spring areas on the quality of examined groundwater. Detailed designed laboratory research and the planned experimental part of this dissertation represent the starting point for solving of complex problems in the field of quality management of drinking water in the investigated area. The special contribution to water protection science is an integrated approach to the analysis of selected organic, inorganic and physicochemical parameters of groundwater, as well as the definition of basic and specific dependent variables, by chemometric data analysis, and the creation of experimental and laboratory conditions for the demanganization of water from critical sources. This is a comprehensive approach to scanning general and specific variables and defining links between elements – grouping them on the basis of their similarities or differences in special classes according to the characteristic physicochemical properties and their ability to complex, which indicates the way of change, its origin in water and defines the causes of their variability (anthropogenic -pointic or diffuse, or native, predominantly geological). All analyzed in situ parameters meet the criterion prescribed by the relevant Regulation on Hygienic Quality of Drinking Water (2003). Out of the 1632 measurements in the laboratory, only 72 parameters and 26 measurements (1.59%) did not meet the criteria prescribed by this Regulation: 15 water measurements from sources Kriškovci (57.6%), 7 from Maglajani sources (26.9%) and 4 from the sources of Laktaši (15.4%). Parameters that deviated from the criteria given in the Regulation (2003) were turbidity, nitrite, manganese, oil and fat. From the microbiological aspect,water source in Laktaši is health safety, while the source of water in Kriškovci is in theworst condition. In water from sources in Maglajani did not detect bacterial indicators of fecal pollution, while the water of the river Vrbas is of very poor quality.Within this doctoral dissertation, a significant contribution was made in the discoveryand understanding of the mutual relations of certain elements and parameters in acomplex system such as water, especially in the view of the analysis of organic andinorganic complexation. Keeping in mind the limited number of literary references,these results represent a significant contribution in this field. It can be concluded from the dissertation that the findings of the tested parameters at the sources change during the year. Therefore, it is necessary to carry out additional geological investigations in order to establish with certainty that there is a connection between the water of the river Vrbas and the water sources. From the dissertation can be concluded that the biological fertilization of the soil and the waste water of the surrounding settlement has an impact on the spring in Kriškovci. For the sources of other two settlements there no has proven that surface activities above the sources affect the source itself and that precipitation does not have a significant impact on them. Conducted tests was based on the basic requirements of the EU Water Framework Directive (WFD) and in the first place on the selection of priority and other substances of interest for the purpose of monitoring and defining pressure indicators and impacts on water bodies. The obtained data will: (1) serve to develop strategies and plans for pollution control and prevention, (2) define programs for monitoring the quality of groundwater and drinking water, (3) enable improved river basin management, and (4) provide availability of information for improving the quality of drinking water.

Cilj ovog rada je ispitivanje mogućnosti uklanjanja visokih koncentracija organskih i neorganskih materija iz vodenih rastvora „Cross-Flow“ nanofiltracijom primenom spiralno uvijenih membrana. Mogućnosti separacije NOM-a, amonijum-jona i ukupnog arsena su ispitivane na koncentratima-otpadnim vodama dobijenim iz industrijskih nanofiltracionih uređaja i obuhvaćeni su eksperimentima serije NFCP. Izdvajanje visokih koncentracija jona kalcijuma, magnezijuma, gvožđa i mangana je ispitivano iz prirodnih podzemnih voda i izvedeno je u eksperimentima serije NFWP. Određeni su optimalni fluksevi i transmembranski pritisci, kao i koncentracije doziranja kompleksirajućih supstanci. Dobijeni poluindustrijski rezultati su praktično primenjivi u velikoj skali za pripremu pijaće vode kako iz dubokih, tako i iz plitkih akvifera. Primena prikazanih rezultata u pripremi vode za piće od vode dubokih izdani uz značajne uštede resursa je namenjena prvenstveno lokacijama u Panonskom basenu. Tretman bunarske vode plitkih izdani je pogodan posebno zbog dodatka organskih kompleksirajućih agenasa koji supstituišu uobičajene postupke deferizacije i demanganizacije i na taj način znatno smanjuju kako investicione, tako i eksploatacione troškove postrojenja. Dobijeni rezultati su poslužili kao osnova za izradu idejnog rešenja industrijskog postrojenja za kondicioniranje pijaće vode od bunarske vode duboke izdani iz regiona grada Zrenjanina, kao i izradu idejnog rešenja industrijskog postrojenja za kondicioniranje pijaće vode od bunarske vode plitke izdani regiona grada Bačke Palanke za naseljeno mesto Despotovo.The goal of this thesis was to examine removal possibility of high concentrations of organic and inorganic matter from aquatic solution using “Cross-flow” spiral wound nanofiltration membranes. Natural organic matter, ammonia ions and total arsenic removal was examined using concentrates – waste water obtained from industrial nanofiltration plant and they present NFCP experiment series. Removal of high concentrations of calcium, magnesium, iron and manganese ions was a part of NFWP experiments and was conducted using natural groundwater. Optimal fluxes and transmembrane pressures, as well as complexing substances dosage concentrations were determined. Obtained results in semi industrial scale are practically applicable on the large scale plants for drinking water preparation from deep wells, as well as from shallow aquifers. Application of presented results, concerning drinking water preparation from deep wells with significant savings of water resources, is designed especially for locations in Pannonia basin. Shallow aquifer well water treatment is applicable in practice especially because of addition of organic complexation agents that substitutes conventional deferization and manganese removal methods ultimately reducing investment and exploitation costs. On the basis of obtained results, industrial plant that produces drinking water from Zrenjanin aquifer deep well was designed. Furthermore, potable water industrial plant was designed that used shallow aquifer well water located in Bačka Palanka region, settlement Despotovo.

Full textAbstract:
Predmet izučavanja ove disertacije je pasivna bioremedijacija naftom i derivatima nafte zagađenih podzemnih voda na lokalitetu Ratno ostrvo i pospešivanje procesa bioremedijacije zemljišta i podzemne vode zagađenih naftom i derivatima nafte na laboratorijskom postrojenju u ciljusanacije ugroženog lokaliteta.Praćenjem podzemnih voda granične zone izvorišta Ratno ostrvo i Rafinerije nafte utvrđeno je da je u podzemnoj vodi granične zone izvorišta Ratno ostrvo i Rafinerije nafte Novi Sad prisutan proces pasivnebioremedijacije, odnosno, da na pojavu ugljovodoničnog zagađenja u vodi sredina odgovara povećanjem brojnosti, pre svega, ugljovodonik-osidujućih i lipolitskih bakterija i bakterijske enzimatske aktivnosti, i dolazi do transformacije mineralnih ulja u polarna jedinjenja. U vodi većine praćenih objekata uočene su eksponencijalne i linearne funkcionalne zavisnosti bakterijske brojnosti i fosfatazne aktivnosti od koncentracije ugljovodoničnog zagađenja za koncentracije ukupnih ugljovodonika < 400 µg/l (najčešće < 200 µg/l). Visok nivo podzemnih voda i prisustvo dela zagađenja u gornjim slojevima zemljišta ukazuje nam na mogućnost primene fitoremedijacije navedenog područja, jer je deo zagađenja dostupan korenskom sistemu.Ispitivanjem tehničke bioremedijacije zemljišta i podzemne vode zagađenih naftom i derivatima nafte na laboratorijskom postrojenju utvrđeno je da dolazi do opadanja koncentracije ukupnih ugljovodonika u zemljištu sa 38,2 na 14,6 g/kg i mineralnih ulja sa 27,0 na 10,2 g/kg (62%), što se može definisati jednačinom C=C0e-kt, gde je konstanta brzine degradacije ugljovodonika k=0,0082 dan-1. U vodi je prisutan veliki broj karboksilnih kiselinanastalih oksidacijom alkana (C10-19), kao i aromata (benzoeva kiselina, kao i benzaldehid), što ukazuje na proces biooksidacije ugljovodonika. Proces rastvaranja i emulgovanja nafte se pospešuje uvođenjem recirkulacije vode: određena je jednačina zavisnosti koncentracije ugljovodonika u vodenoj fazi od koncentracije u čvrstoj fazi, zavisno od brzine proticanja: Cvoda=(f*v+K0)Czemlja, gde je koeficijent ispiranja f=1400 s/m, a difuzioni koeficijent K0=6*10-4. Proces ispiranja nafte i derivata sa zemlje značajno utiče na aktivnost mikroorganizama i razgradnju zagađenja. Sa porastom koncentracije ugljovodonika generalno opadaju brojnosti svih ispitivanih grupa bakterija i fosfatazna aktivnost i određene su granične vrednosti tolerancije. Proces ispiranja se mora voditi tako da koncentracija mineralnih ulja u vodenoj fazi netreba da pređe 15-35 mg/l, a kad se postignu koncentracije ugljovodonika manje od 400 µg/l treba prepustiti pasivnoj bioremedijaciji da ukloni zagađenje.This dissertation investigates the passivebioremediation of groundwater from Ratno Ostrvo contaminated by oil and oil derivatives, and a bench-scale experiment to improve the soil and groundwater bioremediation processes, with the goal of sanatising the effected area.During groundwater monitoring of the zone between the Ratno Ostrvo spring and the Novi Sad oil refinery, a passive bioremediation process was observed, whereby, in the hydrocarbons-contaminated water, increased counts of hydrocarbon-oxidising and lipolytic bacteria and increasing bacterial enzyme activity were found, along with the transformation of mineral oils to polar compounds. In water, the majority of the monitoring points displayed either exponential or linear functionalal dependence between bacterial count or phosphatase activity and hydrocarbon concentration, for total hydrocarbon concentrations < 400 µg/l (most often < 200 µg/l). The high groundwater level and the presence of contamination inthe upper soil layers makes possible the application of phytoremediation at the site, as part of the contamination is in the rhyzosphere.The bench-scale investigation of bioremediation in soil and groundwater contaminated by oil and oil derivatives yielded decreasing concentrations of total hydrocarbons in the soil from 38.2 to 14.6 g/kg and mineral oils from 27.0 to 10.2 g/kg (62%), which can be described by C=C0e-kt, where the rate constant of hydrocarbon degradation is k=0.0082 day-1.In water, a large number of carboxylic acids were present, from the oxidation of alkanes (C10-19) and aromatics (benzoic acid, and also benzaldehyde), which indicates a hydrocarbon biooxidation process. The process of dissolving and emulgating the oil is enhanced by recirculating the water: the linear relation between the concentration of hydrocarbons in the liquid and solid phases was found to be dependent on the flow rate: Cwater=(f*v+K0)Csoil, where the rinsing coefficient f=1400 s/m, and the diffusion coefficient K0=6 x 10-4. The process of rinsing the oil and oil derivatives from the soil significantly influences the microbial activity and the degradation of contaminants. With increasing hydrocarbon concentrations, there was generally decreasing bacterial counts and phosphatase activity, and an upper limit for hydrocarbon tolerance was determined. The rinsing process must becontrolled to ensure the mineral oil concentration in water does not exceed 15-35 mg/l, and once the concentration of hydrocarbons becomes less than 400µg/l, passive bioremediation may be left to complete the degradation.

Ovo podešavanje pH iuklanjanje nepoželjnih mineralnih materija postiže se izvrsnimosobinama ovog zeolita u pogledu filtriranja, ali i ispiranjanakon primene.Maksimalna količina adsorbovanog amonijaka iznosi 2,31 mg(98%) i 2 mg (87%), iz model rastvora i uzorka podzemne,bunarske vode, redno. Prisustvo drugih komponenti ubunarskoj vodi uzrokuje promene u količini adsorbovanogamonijaka na zeolitu. Najbolje uklanjanje postignuto je zajone kalijuma već sa najmanjim masama upotrebljenogzeolita. Nasuprot tome, joni kalcijuma i magnezijuma se prinižim vrednostima doziranja zeolita slabije uklanjaju izbunarske vode, dok sa porastom doziranja raste i efikasnostuklanjanja na svim posmatranim temperaturama.Izbor adsorpcione izoterme je pokazao da najbolje rezultatedaje Freundlich-ova adsorpcione izoterme, a rezultatiaproksimacije ukazuju na fizičku adsorpciju na heterogenojpovršini. Negativne vrednosti entropije aktivacije upućuju nazaključak da se radi o asocijativnoj adsorpciji amonijaka napovršinu zeolita, odnosno da postoji interakcija izmeđuadsorbovanih molekula. Vrednosti entalpije aktivacije od15,096 kJ/mol i 28,978 kJ/mol, za model rastvor i realansistem, redno, upućuju da se radi o endotermnom procesu,što i potvrđuju podaci o ravnotežnim koncentracijama narazličitim temperaturama.Tokom eksperimenata izvedenih sa poluindustrijskomkolonom ispunjenom zeolitom Crystal Right™ (tip CR-100)potvrđena je efikasnost u uklanjanju zeolita iz bunarske vode.Između ispitanih modela za određivanje kinetike u kolonskom uređaju najboljim se pokazao model Yoon-Nelson-a.Koeficijent linearne korelacije za model Yoon-Nelson-a iznosi -0,975, dok je koeficijent determinacije imao vrednosti 0,950.Iako je model razvijen jednokomponentne sisteme pokazaose kao zadovoljovajući iako se radi o realnom sistemupodzemne bunarske vode koja sadrži brojne rastvorenesupstance, katjone zemnoalkalnih i alkalnih metala, huminskekiseline, anjone itd. Može se primetiti da je postignutozadovoljavaće slaganje eksperimentalnih podataka ovremenu probaja sloja (50%) sa Yoon-Nelson-ovim modelom,eksperimentalno određeno vreme proboja sloja iznosi oko 59časova, dok je modelom dobijeno vreme 62 časa. Konstantabrzine Yoon-Nelson-ovog modela iznosi 0,051 1/h.Removing ammonia from groundwater to obtain drinkingwater is an important issue, which is so far solved usingdifferent methods. It is known that zeolites as natural ionexchangers and adsorbents that bind ammonium ions in itsaluminosilicate matrix. Their effectiveness in varioustechnological processes depends on the physical andchemical properties, which are closely related to theirgeological sites, when it comes to natural zeolites. In additionto the natural zeolites in practice synthetic zeolites are used.Today, the commercial application of synthetic zeolites iswidespread in relation to the use of natural, due to the purityof crystal products and uniform particle size. Crystal-Right ™(CR-100) is a zeolite among the most durable mineralsproduced. This zeolite raises the pH of the treated water, whilethe same time it reduces the hardness and remove iron andmanganese. This pH adjustment and removal of undesirablemineral substances is achieved by the excellent characteristicsof the zeolite in terms of filtering, and rinsing after application.The maximum amount of adsorbed ammonia at 2.31 mg(98%) and 2 mg (87%), from the model solution and thesample of groundwater, well water, respectively. The presenceof other components in the well water causes changes in theamount of ammonia adsorbed on zeolite. Selection ofadsorption isotherms showed that the best results areachieved by Freundlich's adsorption isotherm, and the resultsindicate physical adsorption on heterogeneous surfaces.Negative values of entropy of activation lead to theconclusion that it is associative adsorption of ammonia on thesurface of the zeolite, or that there is an interaction betweenthe adsorbed molecules. The values of enthalpy of activationof 15,096 kJ / mol and 28,978 kJ / mol, for the model solutionand real system, respectively, indicating that it is anendothermic process, which is confirmed by data on theequilibrium concentrations at different temperatures.Experiments conducted with the pilot plant column filled withzeolite Crystal Right ™ (type CR-100) confirmed theeffectiveness in removing zeolite from well water. Among thesurveyed models to determine the kinetics of the columndevice Yoon-Nelson's model has proven to be the best. Thelinear correlation coefficient for the model Yoon-Nelson's is -0.975, and the value of the coefficient of determination was 0.950. Although the model developed for one-componentsystems it is proved to be satisfactory for ground waterammonia adsorption. The agreement between experimentaldata on the breakthrough point at 50% concentration (59hours) with Yoon-Nelson's model, is good (62 hours). Constantof Yoon-Nelson's model is 0.051 1 / h.

Solution idea Petrov is stoney bill in south-west part of Brno. You can find magnificent cellar on given land that is probably medieval and is partially carved in rock. Designed building follows up this rock developing to surface, where crystalizes and gradually grows and expands towards from „Šilingrovo náměstí“ to St. Petr and Pavel’s cathedral. Water is the other element – it wells from mouldering diabas rock to surface, thanks to cracked springs that can be found here. That creates a lake beneath Petrov. Water theme is projected to building interiors. This construction is characterised by great views, which are possible because of unique location of the site and the building itself is designed to use the most of them. From terrace, caffeteria and also multipurpose hall can anyone view cathedral, Zelný trh square and Parnas fountain. Function locations 1) Interest-activities more people more life. There used to be one of the oldest schools in Brno from half of 14th century. And because of that, although in modified form, I wanted to preserve this function of the place. I designed one classroom and a multipurpose hall, that can be used e.g. for dance lessons or - in a daytime, when there be no usage for the hall - for rentals for commercial purposes. 2) The entrance to medieval cellar carved into rock, that is under the site. There are two functional water wells, that constantly floods the cellar space. Water will be pumped out to terrace, where it will make a small lake. The whole space will function as a small gallery. 3) Caffeteria and sweetshop are located on very attractive place with spectacular views. Adjoining terrace will serve as summer garden that can be used by public all year round.

Full textAbstract:
The aim of this thesis was simplified design of diaphragm wall affected by excavation from both sides. This wall is a part of temporary shaft that serves for exchange of tunnel boring machines and at the same time it is a permanent structure of an adjacent metro station. Part of the thesis deals with description of construction sequence of diaphragm walls, excavation of the shaft, excavation of the adjacent metro station and following construction of metro tubes and backfilling of the shaft. Inseparable part of the thesis is assessment of geological conditions and geotechnical parameters. Furthermore, a study on temperature loads on struts was carried out and the results of the study were used for design of the struts. To fulfil the requirements of the assignment several models of the shaft structure and adjacent metro station were built in program Plaxis and one model of the diaphragm wall of the shaft was created in program Geo5. The model outputs were subsequently compared to each other. Furthermore a model of lateral support frame was created in program Scia Engineer. Outputs from programs Plaxis and Scia Engineer were used as a basis for design checks of the structure. The design checks were done according to Eurocodes. The diaphragm wall and the lateral support frame were designed to support the loads considered in this thesis. In order to simplify the calculation variable loads from construction machines were not considered and the only variable load considered was the temperature load on struts. Lateral support frame was also designed to accidental load – loss of a strut.

It is a pocket-size map in a form of a book describing the dark side of Brno, fitting contextually within the scope of urban exploration. Locations described within the publication are far beyond the general interest of the majority, and even the alternative minority, of population within the city. These are locations whose visit may result not just in dirty pants or possible conflict with the police, but also in injuries or even death. The inaccessibility of these places is emphasized by the inaccessibility of the map itself, which is being tested at it's very edge of usability. Accurate cartographic mapping is not the intention of this project, neither it is the process of making these places easily accessible. Mediation of their unique atmosphere and providing the evidence of their mere existence is the primary intention here. More so because of the fact that such places are subjects to very fast perdition.

Manifestations of the tidal force have been known to humanity since an- tiquity. The oldest extant remarks on the origin of the tidal force are in the Natural History of Pliny the Elder. He also left us remarks on periodic changes of water-level in wells. This phenomenon does not necessarily have to be connected to the proximity of seas. As such, it is a subject of research since the end of 19th century. Exploring the mechanisms with which the tidal force affects the groundwater level requires combining the findings of geology and hydrogeology but also the knowledge of hydraulics and geomechanics of porous media and certain understanding of astronomy. This thesis contribu- tes to the knowledge of the mechanism of tidal oscillations in groundwater measured in a borehole near Teplice nad Metují in Police Basin. It utilizes models based on the knowledge of geological and hydrogeological structure of the surroundings of the borehole. It investigates the relation between the physical properties of porous media and the amplitude and phase of the tidal oscillations and presents solutions of the models.

This diploma thesis is aimed at the evaluation of water treatment technology in Písty waterworks which treats raw water with high concentration of iron and manganese. The most common method of iron and manganese removal from raw water is based on oxidation to insoluble hydrated oxides followed by separation of formed aggregates. The plant technology consists of aeration, oxidation agent KMnO4 dosing and mixing, sedimentation, filtration and hygienic protection. Chemical analysis of treated water, evaluation of the aeration efficiency of iron and manganese oxidation, evaluation of the separation efficiency of the sedimentation tank and filters, assessment of distribution of iron and manganese in the filter, assessment of dirt holding capacity and optimization of KMnO4 dose were determined. Raw water pH fluctuated around 7,3 during measurements, whereas iron and manganese concentrations in raw water were 6,00 and 0,82 mg.l-1 , respectively. Oxidation of 97,2 % of dissolved iron and of 14,3 % of dissolved manganese was achieved after the aeration. The separation efficiency of the sedimentation tank was 82,9 % for iron and 46,5 % for manganese, however the separation efficiency of the second half of the sedimentation tank was low. Thus, the perforated baffles in the second half of the sedimentation...

Full textAbstract:
In recent decades, it was shown that belowground competition for some plants may take form of the tragedy of the commons (TOC). In these plants, the competing neighbours invest more in root systems than would be appropriate for optimal nutrient uptake for the group and also more than they do when grown alone. However, there is also strong evidence that other species do not follow TOC, and tailor their root system to best nutrient exploitation irrespectively of competitor presence. The root investment strategy of these plants should correspond to the ideal free distribution (IFD). In my thesis I focus on two aspects: I use game theoretical models to explore, whether those strategies can coexist within species and also whether different species can coexist if they have different strategy. From this model I draw predictions, which I test by meta-analysis. Using Agrostis stolonifera as a model, I test assumptions on nutrient and neighbour perception, which underlie TOC and IFD models. I show that according to mathematical models, those two strategies can coexist in different species in a community, but cannot coexist within a species. Within a species, the TOC strategy should always dominate, once it appears. This can be extrapolated to macroevolutionary scale - once TOC occurs in certain clade, it should...

Full textAbstract:
Polychlorinated biphenyls (PCBs) are a class of important organic pollutants which undergo very slow degradation and tend to persist for a long time in the environment. PCBs have various negative effects on living organisms, human health and the environment in general. A method for determining PCB levels in aqueous matrices was developed consisting of solid-phase extraction (SPE) and GC/MS determination. The average recoveries of PCB congeners from artificially spiked deionized water were around 85%. The PCB concentration of 3.3±0.1 μg·l-1 (a sum of selected congeners) was detected in contaminated groundwater originated from the area of a former asphalt concrete producing plant. The most abundant PCBs were trichlorinated congeners which together comprised about 80% of the total PCB content. The optimised SPE method was further applied together with accelerated solvent extraction (ASE) to assess the degradation potential of oyster mushroom (Pleurotus ostreatus) which shows high degradation efficiency of various organic pollutants including PCBs. P. ostreatus belongs to ligninolytic (white-rot) fungi, which is a very promising group of microorganisms frequently studied due to their bioremediation potential.

Full textAbstract:
The ability of the ligninolytic fungus Pleurotus ostreatusto degrade 4 pharmaceutical drugs and 5 compounds which are either used during drug manufacturing or are created as by-products was studied. These compounds were detected in groundwater near a drug manufacturing plant. The maximum concentration levels of the selected compounds in tested groundwater samples variedfrom0.23 µg/lto 227.87 µg/l apart from 1 compound which was not detected in any sample. The degradation efficiency of P. ostreatus was examined with individual compounds as well as with the mixture of all 9 compounds. When degrading individual compounds P. ostreatus lowered the initial concentration (10 mg/l) of 5 compounds by 62-100% after 14-day cultivation in malt extract-glucose medium. When degrading the compound mixture P. ostreatus lowered the initial concentration (2 mg/l of each compound) of 5 compounds by 50-100% after 14-day cultivation in malt extract-glucose medium. Acute toxicity tests with Vibrio fischeri suggest the formation of metabolites which are more toxic than the original compounds. The EC50 value for individual compounds during toxicity tests with Vibrio fischeri was 5.45-131.98 mg/l. Keywords:biodegradation, pharmaceuticals, ligninolytic fungi, Pleurotus ostreatus, groundwater, toxicity, Vibrio fischeri

Full textAbstract:
This thesis deals with the areal survey of water resources in the area of Priessnitz baths, to search for natural medicinal sources and advanced data collection for evaluation radiohydrogeochemical situation of the area. The area of interest is situated in the Hrubý Jeseník mountains. Hydrogeologically it is a hard rock, which consists mainly of metamorphic rocks of the Bohemian Massif, the Moravian-Silesian region, presented as the methamorfic envelope of the desen group of Silenics. Altogether, 83 objects were recorded and many of them were visited repeatedly. Physical parameters (temperature, pH, Eh, conductivity), activity 222Rn and flow rate were measured. In addition, the chemical composition and tritium contents were determined on selected sources. Conductometry, thermometry, and probes for peloids were conducted. There was no source of water (or peloid) that would reach the criteria of a natural healing source (according to the Czech spa law). However, the overall hydrogeological and hydrochemical situation is quite complicated. Both the genesis of water and its chemical composition is highly heterogeneous and influenced by the heterogenical geological structure. Generally, we have distinguished three types of water according to the chemical composition. We also divided the water sources...

Full textAbstract:
My thesis is a part of the project GACR 206/06/0058 Monitoring of selected heavy metals and risk elements in a wastewater cleaning process in artificial wetlands. The goal is to evaluate temporal and spatial variability of underground biomass of Phragmites australis in the artificial wetland used for wastewater treatment in Slavošovice. The destructive method was used for the sampling. The aboveground biomass was determined from six samples taken at the inflow and six samples at the outflow. The belowground biomass (in 2008) was estimated from two samples taken at the inflow and two samples at the outflow. In 2009, the belowground biomass was determined from six samples taken from the inflow and six samples from the outflow. The analysis of the root structure was determined from 12 samples collected at the inflow and 12 samples of the outflow. The mean total aboveground biomass reached 1039 g.m-2 at the inflow and the 1749 g.m-2 at the outflow. Average total belowground biomass in 2009 reached the inflow 1718 g.m-2 and 1562 g.m-2 at the outflow. The average total length of roots growing from one node to was 284,7 m.m-2 and 324,9 m.m-2 in the inflow and outflow part, respectively. Average specific root length of the inflow was 2589,5 cm.g-1 and the outflow 2956,9 cm.g-1. The average total length of roots reaching the inflow of two kilometers and three kilometers of inflow.
