This diploma´s thesis aims to model the hydraulic model of the Brno – Ivanovice water supply system. The software MIKE URBAN for model hydraulic model of water supply system was used. It was performed a simulation of the various states of loading. The water supply system was assessment of pressure ratios. The outcome of this work is calibrated hydraulic model of water supply system. The appendix consists also of drawings, which represented pressure ratios, which are situated on water supply system. On the fourth drawing is described transparent situation of Brno-Ivanovice water supply system.

Diploma thesis deals with design of a flood protection a controlling structures with respect to problém of inner waters in the area of interest. The river reaches assessed are located mostly in the urban area of the city Letovice, more precisely from the junction of the Svitava and Křetínka river. The reaches are at kilometer 59,608 – 61,520 of the Svitava and kilometer 0-1,752 of the Křetínka river including the race between them. Program MIKE 11 (developed by Danish hydraulic institut) was used to calculate the water levels as nonuniform flow.

This study was stimulated by a publication of Mr Mike Bosch (Bosch 2007) that Cereus jamacaru DC (Cactaceae) used by him on his farm is effective for gastrointestinal nematode control in livestock. This plant, widely known as Queen of the night, is a serious invasive weed. We evaluated this claim in in vitro assays and in vivo experiments in sheep experimentally infected with Haemonchus contortus and Trichostrongylus colubriformis. This is the first report of such an anthelmintic trial in livestock involving C. jamacaru. The first study was to repeat the farmer’s work under strictly controlled conditions. In vivo studies were conducted to determine the possible direct anthelmintic effects of C. Jamacaru on ovine gastrointestinal nematodes. Eighteen sheep were allocated to three groups and were infected with 4000 H. Contortus and 6000 T. Colubriformis infective larvae given in 3 divided doses over a period of three days. From day 0 until day 49 of the experiment, sheep were drenched once a week with fresh blended C. jamacaru plants with the core removed at the same (32.33 g/sheep) or double the dose (64.66 g/sheep) used by Mr Bosch. No negative effects of the double dose were observed during the period of the experiment. Faeces were collected twice a week for faecal egg count. Based on the in vivo experiments, C. Jamacaru was not effective in reducing H. Contortus and T. Colubriformis in sheep to the 70% reduction levels of the control treatments considered to be a useful reduction in FEC. Nevertheless, its in vivo activity was substantial at the higher dose and reduced the FECs by 65%. To investigate the matter further some additional experiments were carried out. Specimens of C. Jamacaru were collected and dried in the shade. For the phytochemical analysis and in vitro experiments, the dried material was milled to a fine powder, it was extracted with acetone and five fractions (hexane, butanol, water, chloroform and 35% water in methanol) were obtained by solvent-solvent fractionation. The chemical composition of the fractions and crude extract was analysed by thin layer chromatography using three solvent systems of varying polarity and pH. To detect the separated compounds, vanillin-sulphuric acid-methanol was sprayed on the chromatograms and heated at 110°C for optimal colour development. The antioxidant activity in plant extracts may influence the immune systems of animals and have an indirect effect. The antioxidant activity was therefore determined. For qualitative analysis of antioxidant activity, the 2,2, diphenyl-1-picrylhydrazyl (DPPH) assay on TLC plates was used as a test for the radical scavenging ability of the compounds present in the different extracts. In the DPPH qualitative analysis of antioxidant activity there were a number of antioxidant compounds present in some of the extracts and fractions but the activity appeared to be low. This observation was confirmed in the TEAC quantitative analysis of antioxidant activity. Even the fraction with the highest activity was about 8 times less active than trolox or ascorbic acid. It therefore appears that stimulation of the immune system by antioxidant activity does not explain the results found on the farm. The antibacterial and antifungal activities were determined against 4 bacteria (Staphylococcus aureus, Enterococcus faecalis, Escherichia coli and Pseudomonas aeruginosa) and 3 fungi (Aspergillus fumigatus, Candida albicans and Cryptococcus neoformans). The minimum inhibitory concentration (MIC) values for plant extracts varied from 0.04 to 2.5 mg/ml. E. coli was the most sensitive and the fungi were in general resistant to the extract and fractions. In general the activity was not very good, especially if the dosage in an aqueous system on the farm is considered. Antimicrobial activity also does not explain the results obtained. The nematocidal activity was evaluated by an egg hatch assay and larval development viability assay (LDVA) in vitro. The acetone extract inhibited egg hatchability and killed infective larvae of H. Contortus nematodes of sheep in a concentration-dependent manner. The percentage inhibition of egg hatching of the acetone extract and the butanol, chloroform, 35% water in methanol, hexane and water solvent-solvent fractions were 100%, 100%, 94%, 91%, 9% and 16%, respectively. The percentage inhibition of larval development of the acetone extract and chloroform, 35% water in methanol, hexane and water fractions were 93%, 84%, 49%, 85%, 31%, respectively. The chloroform fraction was significantly more active than all the other fractions (p<0.05). The extracts had in vitro activity against the nematodes. The activity was however much lower than the positive control, albendazole. It is disappointing that our results do not provide an explanation for the success obtained by Mr Bosch on his farm. Even if we do not understand how it works it may be useful to prepare suitable dosages (using low level technologies adaptable to rural conditions) for use by resource-poor rural communities where C. jamacaru occurs as an invasive weed.

Currently there are urgent water related problems, such as use of groundwater and surface water resources, which need a more integrated view on the hydraulic cycle and how the different processes interact with each other. This has led to new ways of thinking in management of watersheds, which sparked the creation of new integrated tools for flow characterization. Characterization of a watersheds flow is an important step in future research regarding water quality and climate change issues. The Krycklan catchment, located in the northern part of Sweden, has been under research for many years. With a great deal of measurements regarding stream water chemistry as well as climate measurements (evaporation, transpiration and temperature), the catchment has great potential regarding solute transportation and climate change investigation. This thesis was made to aid in future research by characterization of the catchments groundwater and surface flow, by the use of an integrated model software tool, MIKE-SHE. The model have been calibrated and validated with the help of real time observed measurements at Krycklan combined with model data from SMHI:s HYPE-model. Throughout the calibration it was discovered that the hydraulic conductivities were important for the surface and groundwater interaction, regulating base flow as well as peak flows. The shape and timing of the spring flood was also affected by the snow melt while the summer peaks for the upstream rivers, probably due to the relatively large difference in topography elevation, were more affected by the representation of the topography created by the grid size. A smaller grid-size resulted in a finer representation of the topography, which resulted in a quicker runoff to the upstream rivers without an increase of base flow. This gave better fitted hydrographs of the flows in the upstream rivers compared to observed measurements. The final model created was able to capture the discharge-hydrograph and groundwater fluctuations with small error and high correlation coefficients compared to observed data and model data from SMHI. The results as well as the calibration process helped with a deeper understanding of the modeling tool itself as well. Future improvements that can be considered are to introduce new calibration data and the use of an even smaller grid size. This can improve the understanding of the catchment as well as the representation of the flow in the upstream rivers. However, the effects of a smaller grid size must be reflected upon. The model will most likely become more unstable and the run time of the model will greatly increase. One suggestion to solve this issue is to look into a sub-catchment to reduce these complications.

Mälaren är en mycket viktig dricksvattentäkt för många människor. I den här studien utreds riskfaktorersom kan påverka råvattenkvaliteten i Mälaren och sedan relateras dessa till hydrodynamiskmodellering av Mälaren. Hydrodynamisk modellering är ett modernt verktyg som kan simulera vattnets rörelse och tar hänsyn till många hydrodynamiska och meteorologiska drivvariabler. Modellerkan användas för att till exempel förutse transport av punktutsläpp och beräkna när och vilken koncentration som kommer till ett vattenverks intag. Beställaren av detta projekt är Norrvatten, en dricksvattenproducent som är intresserad av utvecklingsmöjligheterna hos oceanografen Göran Broströms tillämpning av den hydrodynamiska modellen MITgcm. Norrvatten använder sig idag av en modell vid namn MIKE 3 FM skapad av DHI. De är intresserade av vilken utveckling av MITgcm som skulle behövas för att den ska uppnå liknande kvalitetskrav som deras nuvarande modell gör. I en litteraturstudie samlades information om Mälarens fysikaliska, biologiska, kemiska förutsättningar samt information om hydrodynamisk modellering, för att göra en analys kring Mälarens råvattenkvalitet såväl som modellering av Mälaren. Genom kvalitativa intervjuer med Göran Broström angående MITgcm samt Helene Ejhed, uppströmsansvarig på Norrvatten som ofta använder MIKE 3 FM var det möjligt att ingående analysera modellerna utifrån såväl drivdata som modellernas övergripande kapaciteter. Utöver analys från intervjuerna gjordes en körning av Göran Broströms tillämpning av MITgcm. Resultaten visade att de största riskerna gällande Mälarens råvattenkvalitet är oljeutsläpp från närliggande farleder och patogener som släpps ut från reningsverk. Jämförelsen mellan MIKE 3 FM och MITgcm etablerade många likheter mellan modellerna, även om vissa variabler skilde sig åt, såsom in- och utflöden, ytvågor och nederbörd. Förslag på en ordning som Göran Broströms modell kan byggas ut på presenteras i form av en prioriteringspyramid. Validering av modellen visade sigvara ett viktigt första steg i utvecklingen samt att förbättra interaktionsdesignen. Utveckling av modellen skulle resultera i vissa kostnader för Norrvatten. Vidare studier behöver bidra med en större förståelse över den tillämpning Broström gjort av MITgcm samt jämförelser med flera modeller.

To facilitate the process of setting up small scale environmental models in coastal and offshore areas a wave model and a 2D current model for the Baltic Sea have been set up with MIKE 21. The ambition is that the Baltic Sea model can serve as a source of boundary conditions for local models. The main focus in the project has been to determine which input data to use to get the best results and then to calibrate and validate the model with the best data sets available. The wave model has been tested with three different sources of wind forcing and the results with the different sources are evaluated. The wave model has been calibrated and validated against five wave buoys and the current model against three current observation stations. The comparison shows that the wave model gives good estimations of wave height, period and direction. The output of the current model coincides with observations where distinct current patterns exist. The wave model is considered a good source to extract wave statistics from for the entire Baltic Sea. The current model can be used for scenarios or areas that do not suffer from the limitations of a 2D model.

An increase in the frequency and intensity of storm events is predicted by numerous climate researchers for the north of Europe. Not only this but also landuse change in form of clear-cutting can have an impact on the discharge of rivers and with that on road drainage structures. Extensive societal costs can be the consequences of blockage and underdimensioned structures. Hydrological models are powerful instruments that can be used to assess the future dimension requirements for road drainage structures especially in specifically vulnerable areas. In this thesis the hydrological model MIKE SHE was set up to study the discharge and water level at two pipe bridges and one culvert within the catchment of the river Hakerud in Västra Götaland, Sweden. Three scenarios were considered including a changing climate until 2050 and 2100 and a clear-cut scenario aiming to find out if the current design is sufficient for the future. This model can be used as an example model set-up for similar studies taking the recommendations of the experience gained in this thesis into consideration. For the Swedish Transport Administration further studies on this basis can contribute to decision making on the dimensioning of road drainage structures in the future to ensure a safe and robust infrastructural system.

Indiana University-Purdue University Indianapolis (IUPUI) / This thesis analyzes the gender narrative surrounding the vice-presidency and the 2016 election. It reviews the traditional feminine gender roles assigned to the vice-presidency and as evidenced in Governor Mike Pence’s participation in a 60 Minutes interview, nomination speech at the 2016 national convention, and vice-presidential debate. Furthers the work of Bostdorff, who argued that the vice presidency has a traditional feminine role where vice-presidential figures and potential aspirants use strategies of celebration, confrontation, vindication, and submission to fulfill a gendered role in service to a highly masculine presidency. Suggests that the realities of the 2016 election allowed for these strategies, although in a different form given the nature of the campaign and a Trump candidacy.
