The subject of this diploma thesis is a research of bituminous binder modification by fast react-ing polymer SBS. The theoretical part covers an introduction to bituminous binders, their pro-duction, chemical and physical-mechanical properties. The identification of bituminous binders and their use in bituminous mixtures is briefly described. To conclude, current modification methods are described in detail and important modifiers are introduced. In the practical part, three applied tests (softening point, elastic recovery and penetration) are described in detail. The bituminous binders tested (20/30, 30/45, 70/100, PMB 25/55-55 and PMB 45/80-50) and the fast-reacting polymer SBS are introduced. Samples with two weight percentages of SBS, 7,5% and 10%, are produced. Two mixing times, 60 seconds and 600 seconds were used to mix the bituminous binder and SBS. In conclusion, the results are evaluated and commented. Further research suggestions regarding this field are recommended.

The thesis is dedicated to creation more accurated raster of the cadastral map in the cadastral district Těchanov. In the introductory part theoretical findings from the area of more accurate transformation are summarized and several terms related to raster problemacy are explained. The following chapter deals with the used software. Another part deals with description of the practical part, i.e. making out transformational key accurating transformation. The final chapters are dedicated to verifying the result of transformation by an independent control using the comparison of lenghts directly measured in terrain, measured on the original map of land cadastral or cadastral map and lenghts discovered from raster scan images before and after accurating transformation.

This work presents the topic of data mining on the web. It is focused on clustering. The aim of this project was to study the field of clustering and to implement clustering through the k-means algorithm. Then, the algorithm was tested on a dataset of text documents and on data extracted from web. This clustering method was implemented by means of Java technologies.

The multi-purpose exhibition hall and office building with the facilities is located in front of the manufacturing estate, situated in a green belt near the main access road. The height of the main office building helps to create a point of reference for the entire plant. A unique textile – lateral facade - STAMISOL FT 381 – is divided into basic, regular, quadratic segments. The textile facade is made to evoke a paper sheet. The exhibition pavilion is acros from the Office tower. The idea was to pick up on old industrial building design. Bringing the architecture into harmony with nature was also a key point of the design. Using a rough CORTEN steel construction parts in tree – shaped design was a purpose. The connecting tunnels are here to remind on old industrial conveyors. The office building rises out of ground wave in which all facilities, storage areas, waste managment units, and stuff parking lots are located. Ground wave also screens out the storage and facilities A lagoon serves as a integrating element for all building stuctures.

Sinking Creek, located in upper east Tennessee, is on the 303(d) list for not meeting minimum water quality standards for recreation. A Total Maximum Daily Load (TMDL) for fecal coliforms was developed. The purpose of this study was to investigate the use of water quality parameters to identify areas that contribute to the fecal coliform loading. Concentrations of nitrate-N, orthophosphates, BOD, alkalinity, hardness, and optical brighteners (OB) were monitored at fourteen stations monthly for one year. Site 3 (agricultural region) exhibited the highest average nitrate-N loadings (627.34 mg/sec) and orthophosphate (as PO43-) loadings (84.83 mg/sec). Alkalinity loadings ranged from 10.00 mg as CaCO3/sec to 163,500.00 mgCaCO3/sec. Hardness loadings ranged from 2.00 mg as CaCO3/sec to 96,200.00 mgCaCO3/sec. The agricultural sites exhibited higher loadings for all water quality parameters measured (except OB) than the urban and forest areas. Nutrient loadings appeared to be related to agricultural land use patterns.

This study was carried out to evaluate the performance of Soil Aquifer Treatment (SAT) under different loading regimes, using wastewater of much higher strength than usually encountered in SAT systems, and also to investigate the removal of the endocrine disruptors triclocarban (TCC), estrone (E1), 17¿-estradiol (E2) and 17¿- ethinylestradiol (EE2). SAT was simulated in the laboratory using a series of soil columns under saturated and unsaturated conditions. Investigation of the removal of Chemical Oxygen Demand (COD), Biochemical Oxygen Demand (BOD), Dissolved Organic Carbon (DOC), nitrogen and phosphate in a 2 meter long saturated soil column under a combination of constant hydraulic loading rates (HLRs) and variable COD concentrations as well as variable HLR under constant COD showed that at fixed HLR, a decrease in the influent concentrations of DOC, BOD, total nitrogen and phosphate improved their removal efficiencies. It was found that COD mass loading applied as low COD wastewater infiltrated over short residence times would provide better effluent quality than the same mass applied as a COD with higher concentration at long residence times. On the other hand relatively high concentrations coupled with long residence time gave better removal efficiency for organic nitrogen. Phosphate removal though poor under all experimental conditions, was better at low HLRs. In 1 meter saturated and unsaturated soil columns, E2 was the most easily removed estrogen, while EE2 was the least removed. Reducing the thickness of the unsaturated zone had a negative impact on removal efficiencies of the estrogens whereas increased DOC improved the removal in the saturated columns. Better removal efficiencies were also obtained at lower HLRs and in the presence of silt and clay. Sorption and biodegradation were found to be responsible for TCC removal in a 300 mm long saturated soil column, the latter mechanism however being unsustainable. TCC removal efficiency was dependent on the applied concentration and decreased over time and increased with column depth. Within the duration of the experimental run, TCC negatively impacted on treatment performance, possibly due to its antibacterial property, as evidenced by a reduction in COD removals in the column. COD in the 2 meter column under saturated conditions was modelled successfully with the advection dispersion equation with coupled Monod kinetics. Empirical models were also developed for the removal of TCC and EE2 under saturated and unsaturated conditions respectively. The empirical models predicted the TCC and EE2 removal profiles well. There is however the need for validation of the models developed / Netherlands Organisation for International Cooperation in Higher Education (Nuffic) / The Appendix files for this thesis are unavailable online via Bradford Scholars.

Corporate Governance (CG) nowadays is on the agenda of most developed and developing countries, including Jordan, and is receiving considerable attention in the business world as well as in the area of academic research, which is an indication of its importance for business development and society as a whole. The knowledge base about CG in developing countries appears to be limited, but it is growing in size and importance. This study therefore aims to investigate current CG practices and barriers to the development of good CG practices in firms. In order to accomplish the research objectives, a mixed research methodology was adopted. The findings of the study contribute to knowledge by providing empirical data to test and extend the theory of CG. The results suggest that most big and old firms are applying best practice of good CG. Regarding factors inhibiting the practice of effective CG, the results indicate that weakness of the legal environment for firms and lack of knowledge of BODs about CG principles are the most important factors. The empirical results find that constitution, compliance and conscience will affect firm’s performance positively. Separation between the position of CEO and Chairman, the existence of independent NEDs, the use of board subcommittees and a strong disclosure regime also help firms to improve performance. On the basis of the empirical results, the study recommends that the government needs to reform the relevant legislation. These suggestions may strengthen the internal governance of firms, thereby increasing performance and maximise shareholders’ wealth.

Industriell vattenrening är ett extremt viktigt område inom Miljöskyddsteknik då 60% av allt sötvatten inom Sverige används av industrier. Substanser som PFAS, aromatiska textilfärger, fenol och läkemedelsrester är extra utmanande då dessa kan vara gifta för biologisk rening. Syftet med denna rapport var att först redogöra några av de viktigaste avvägningarna som behöver göras när ett industriellt vattenreningsverk designas. I del två av arbetet har en kartläggning av teknologier som kan användas för att assistera eller ersätta biologisk rening. Det existerar flera olika typer av tekniker för att ersätta biologisk rening, men majoriteten av dessa konsumerar stora mängder värme eller elektricitet, vilket kan leda till stora rörliga kostnader. En trend inom industriell vattenrening är elektrifiering. Elektrifiering ger möjlighet att återvinna kemikalier, selektiv separation av joner, automatisk justering av pH via tekniker som elektrodialys och elektrokoagulering. Kall plasmaoxidation och kavitation kan även användas för destruktion av organiska ämnen. I takt med att förnyelsebar energi blir billigare att producera och om regeringen inför el-subventioner för industrin så kommer användbarheten av dessa tekniker att öka. Membranprocesser kan användas för att intensifiera processer som extraktion och indunstning. Med hjälp av membran kan separationshastigheten och energianvändningen minskas. Enzym kan användas för att skräddarsy rening för att bryta ner specifika ämnen vid låga tryck och temperaturer. Skumseparation är en mycket lovande process som kan användas för separation av ytaktiva ämnen som PFAS och har en mycket enkel design och låga energikostnader. / Industrial water treatment is an important field of study as industries in Sweden consumes over 60% of the available freshwater. Furthermore, only 60% of the industrial wastewater in Europe receive treatment before its discharged. Hard to oxidize compounds such as dyes, phenol, and PFAS are a major problem within the field as they often exhibit toxic or inhibiting qualities towards biological treatment methods. Therefore, the purpose of this thesis is twofold; firstly, some of the most important considerations when designing an industrial wastewater treatment plant is discussed to aid someone new to the field. Secondly, novel technologies that could be used to support or replace biological treatment methods are discussed. There exist several different novel technologies that can be used to treat organic pollutants. However, many of these techniques are very energy intensive, leading to high operational costs. A major trend within wastewater treatment is the electrification of treatment techniques. These enables the recycling of chemicals, selective removal of ions and automatic neutralization of pH by means of electrodialysis and electrocoagulation. They can also be used for destruction of organics using cavitation or cold plasma oxidation. The usefulness of these techniques is likely to increase in the future as the electrification of industry picks up speed and subsidies on industrial electricity prices are put in place. Membrane processes can intensify already existing unit operations such as evaporation and extraction. By employing a membrane, the speed of separation and the energy use can be lowered. Enzymatic treatment can be used to degrade several different compounds at low temperatures and pressures by tailoring the mix of enzymes to perfectly fit the wastewater in question. Foam separation is also interesting technology in the removal of surface-active chemicals and compounds due to its simplistic design and low operational cost. The use of this technology is likely to increase in the future if the legislation regarding persistent organics is tightened further.

TITLE Spatial generalizations of the properties of the triangle AUTHOR Jirˇı' Sřubarˇ SUPERVISOR Prof. RNDr. Adolf Karger, DrSc. DEPARTMENT Department of mathematics education ABSTRACT The present thesis describes various interesting properties of a triangle. The aim is to find and prove similar properties of its spatial generalization - a tetrahedron. Even though both synthetic and computational methods are used for proving spatial relations, synthetic approach is preferred whenever possible. The thesis is divided into two parts. In the first part, the properties of the tetrahedron analogous to the centroid and the orthocenter of the triangle are described. Also, conditions on the existence of the orthocenter of the tetrahedron are derived. Moreover, for tetrahedrons without an orthocenter, the so-called Monge point is introduced as its generalization. In the second part of the thesis, some further properties of the triangle are studied - - the Simson line, the de Longchamps point, the nine-point circle, the Euler line, the Lemoine point, the isodynamic points, the Lemoine axis and the Brocard axis. As the main contribution of the present thesis we define and prove the existence of spatial analogues of the above mentioned properties for the tetrahedron - the de Longchamps point, the twelve-point and...
