Title: Study of satisfaction of Czech beachvolleyball championship participants compared to analogous foreign tournaments Aims: The main aim of this diploma thesis is to determine satisfaction of beach volleyball players with the Czech beachvolleyball championship in Opava 2020 in comparation with foreign tournaments. Following these results recommendations and advice for improvement of the Czech beachvolleyball championship are proposed. Methodology: The main methods used in this thesis are electronic questionnaires and semi- structured interviews. Creation of the questionnaire was inspired by the SERVIMPERF method and Brady's model. The questionnaire was investigating 26 attributes overall. The data set consists of players from Czech's beach volleyball's national team. Interviews were conducted with two national team players, and the aim was primarily to add to the information obtained from the electronic questionnaires. Results: The obtained data is interpretated via graphs, mostly by cross-tab classification and tables. These data showed that the players were not content with the vast majority of investigated attributes of the 2020 Czech beachvolleyball championships. Comparatively, the foreign tournaments are in most of the attributes satisfying. In the resulting comparison the foreign...

Östersjön har flertalet regionala miljöproblem, exempelvis övergödning samt höga halter av tungmetaller vilka beror på mänsklig påverkan. På Gotland spolas det årligen upp stora mängder släke, alger och vattenlevande växter på stränderna, som idag inte nyttjas i större utsträckning. Denna rapport syftar att bedöma lämpligheten att använda det gotländska släket för produktion av biokol. Under denna studie har ett studiebesök till Gotland, flertalet intervjuer samt en litteraturstudie genomförts vilka lagt grund för beräkningar av energi- och materialbalanser kopplat till släkesbaserad biokolsproduktion. Släket har ett kadmiuminnehåll på cirka 0,9 mg/kg och består till 80 % av vatten, där vanligt förekommande arter är bland annat bandtång och kräkel. För beräkningar av energi- och materialbalanser nyttjades två olika förbehandlingsalternativ av släket, där alternativ A var en värmebehandling och alternativ B innefattar en kompostering samt avlsutande värmebehandling. Alternativ B är mer energieffektiv sett till energiförbrukning per kilo producerat biokol vilket var 14,5 MJ/kg jämfört med 29,8 MJ/kg. Det finns både för- och nackdelar med användning av släke för biokolsproduktion. Släke är en outnyttjad resurs som kan ingå i biokolsframställning, dock är processen energikrävande på grund av det höga vatteninnehållet i biomassan. Användningen av ett kadmiumrikt biokol är även problematiskt i och med risken för utlakning av denna tungmetall. Utifrån resultatet är det därmed svårt att bedöma lämpligheten av ett släkesbaserat biokol. / The Baltic sea has multiple environmental problems, such as over-fertilization and high concentration of certain heavy metals, caused by human activity. Yearly, beach-cast is washed up on the shores of Gotland and this biomass is today not utilised to a considerable extent. This report aims to assess the suitability of producing biochar from the left over beach-cast. During this study a visit to Gotland, interviews and a literature study has been completed, which has laid the groundwork for calculations of energy and material balances regarding algae-based biochar production. The beach-cast contains approximately 0.9 mg cadmium per kg and consists of 80 % water, in which common species found are eelgrass and furcellaria, among others. For the calculations of energy- and material balances, two different pretreatment alternatives were used before the pyrolysis. Alternative A simply uses preheating and alternative B consist of a composting step before a finishing preheating session. The most energy efficient was alternative B as the power consumption per kilo produced biochar was 14,5 MJ/kg compared to 29,8 MJ/kg. The use of beach-cast for manufacturing biochar has benefits as well as disadvantages. Beach-cast is an unexploited resource that could be used for biochar production, but on the other hand the process is demanding energy-wise due to the high amount of water in the biomass. The utilisation of cadmium rich biochar is also problematic due to the risk of the heavy metal leaching. Based on the results it is therefore complicated to estimate the suitability of a beach-cast based biochar.

“Valparaiso, Round The Horn”, a collection of short stories, contends with the following vital concerns: How are we transported? Why do we believe each other? What is our tendency towards legend? How do we immortalize one another? What is ritual to the avowed non-believer? How can we feel such heartbreak about someone who died before we were born? Will we ever understand each other? Is there grace in misunderstanding? Is there genius in it? A long time ago, could people run as fast as horses? What is the use in anything less than myth?

Accumulation of beach cast biomass on coastal zones around Gotland is an increasing problem that reduce the recreational value of beaches and cause environmental degradation of coastal environments. Beach cast was once regularly harvested on Gotland, as it was considered a valued biofertilizer, but as it seized to be used in combination with the eutrophication of the Baltic sea, beach cast accumulation has increased in scale. The use of beach cast as a resource for bioenergy and agriculture does not only provide important services that can replace the use of greenhouse gases and finite resources but can also mitigate eutrophication and increase the quality of coastal zones as nutrients are retrieved from the water. Macroalgae and seaweeds are hyperaccumulators of heavy metals which pose a challenge for the utilization of beach cast as a fertilizer. Especially cadmium, a heavy metal that is harmful for human consumption, is strictly regulated and limits the amount of beach cast that can be used for agriculture. This thesis has analysed the potential benefit of beach cast harvesting and three potential utilization strategies of beach cast; fertilizer to food crops, fertilizer to fast growing energy forest (Salix) and biogas production with digestate utilization. The result indicate that all strategies are possible and viable utilization strategies under certain conditions. Because of the complex and site specific factors that affect beach cast utilization, adapting strategies depending on the conditions and needs of the local coastal zones is required. Cadmium uptake is affected by a range of factors that can be controlled so that beach cast can provide nutrients and improve soil structure without contaminating the soil. Especially promising is the prospect of fertilizing Salix with beach cast as the cadmium absorption and growth rate of Salix enables large amounts of beach cast to be spread without risk for it accumulating in the soil. The cadmium contained within the Salix can later be removed from the environment entirely as it is collected from the ash when Salix is converted to bioenergy. Recent studies also indicate that food crops can be safely fertilized with beach cast without cadmium being transferred if specific crops are chosen. Cadmium uptake to crops can also be limited if specific beach cast with low cadmium content are used and if the beach cast is pre-composted with other substrates. Both for Salix and food crops its instead legal restraints on cadmium spreading that limits the use of beach cast. When abiding by the set cadmium restrictions, beach cast can only marginally supply the macronutrient requirement of the average food crop on Gotland. Biogas production and digestate utilization from beach cast provides many environmental benefits as clean renewable energy is generated that can replace fossil fuels and the nutrients contained in the digestate can be spread on arable land. From the conducted energy balance of the system on Gotland it was found that beach cast has theoretically good conditions to ferment beach cast. However, beach cast isn’t practically viable on Gotland because the substrate can’t compete financially with other available substrates and it requires costly pre-treatments. Regardless of which beach cast utilization strategy chosen, harvesting is concluded to have a positive effect on mitigating coastal eutrophication and beach and water quality. Although it cannot on its own mitigate a net nutrient loading to coastal zones in Gotland, harvesting easily available beach cast can reduce the nutrient loading to coastal zones on Gotland with up to 27 % and 4,5 % phosphorus and nitrogen respectively.

Successful translocation of a listed species into an area of previous occupation requires knowledge of the habitat needs. The presence of the necessary food items is critical to the successful establishment of a new population; this information is unknown for Peromyscus polionotus niveiventris, the southeastern beach mouse, a threatened subspecies on the east coast of Florida. I used fecal and stable isotope analysis to determine the diet of this subspecies at Cape Canaveral Air Force Station, Brevard County, Florida, between the autumn of 2003 and the spring of 2005. Six trapping grids were established, three in the dune/swale and three in the coastal scrub communities. Fecal and hair samples were collected and analyzed. The diet varied in the amount of 13C consumed between habitats and in the amount of both 15N and 13C consumed among grids within a habitat. There was no significant interaction between habitat and sex in the amount of either 15N or 13C consumed, and sexes also did not differ significantly. Fecal analysis uncovered the dominance in the diet of C3 plants. My data refuted the current belief, that the southeastern beach mouse prefers beach grass seeds of C4 plants, which were consumed but not in the frequency or quantity expected. I also analyzed the diet of Peromyscus gossypinus, the cotton mouse, and Sigmodon hispidus, the hispid cotton rat, using the two techniques. Both species consumed a combination of plant and arthropod material. Their diets varied between dune/swale and coastal scrub habitats. All three species' diets were significantly different, with Peromyscus polionotus niveiventris and Peromyscus gossypinus being the most similar. Both consume a greater proportion of arthropod material compared to the hispid cotton rat. Interspecific competition between the southeastern beach mouse and the cotton mouse may occur in times of limited resources.

The design and maintenance of Marine Oil and LNG Terminals is governed by the Marine Oil Terminal Engineering and Maintenance Standards (MOTEMS) which is part of the 2010 Title 24 California Code of Regulations, Part 2, California Building Code, Chapter 31F: Marine Oil Terminals. The purpose of this thesis is to evaluate the current recommendations for the in-ground plastic hinge length and depth for piles in section 7 of MOTEMS for all typical soil properties and pile dimensions found in Marine Oil and LNG Terminals. The pile types considered in this analysis are 24-inch octagonal prestressed concrete piles and 24-, 36-, and 48-inch steel pipe piles in varying soil conditions. Existing recommendations for plastic hinges are incomplete and inadequate. MOTEMS does not have any recommendations for plastic hinge depth, only length, nor does it have any recommendations for in-ground plastic hinge for steel piles. Recommendations for steel piles are however found in the Port of Long Beach Wharf Design Criteria (POLB), but the recommendations in both MOTEMS and POLB have shown to be inadequate for both steel and prestressed concrete piles. MOTEMS also proves to be adequate for Level 2 earthquakes but not for Level 1. The plastic hinge length for Level 1 is much longer than that for Level 2. So the MOTEMS recommendations for Level 1 lead to conservatively small displacement capacity. POLB recommendations are also adequate for Level 2 but not Level 1 for concrete and are overly conservative for steal and therefore, not adequate for either level except in dense and medium sands during a Level 1earthquake. POLB does not take into account different soil characteristics and has one value for all soils, which is inadequate for most cases.

This essay analyzes the cultural concepts of wilderness, utopia, and the pastoral in relation to The Beach from ecocritical and postcolonial perspectives. Evidently, the pastoral is critical in shaping the Western idea of wilderness, and the utopistic mindset plays an equally crucial role in wilderness gazing. The backpackers in the novel seek authenticity—which they feel their everyday lives lack in society—in the remote, ostensibly pristine nature to escape people like themselves. As established in the analysis, the beach dwellers thus undermine their own ideologies when colonizing both nature and people and, in some ways, culturally slum their existence at the beach. They feel better about themselves when living under so-called harder conditions with moderated luxuries and provisions; this ultimately presents how the Western backpacker’s view of nature and indigenous cultures is highly influenced by American pop culture.

<p> The open water season of Radstock Bay is less than three months long and varies considerably from year to year. The break-up and ablation sequence of the bay is regular and systematic, commencing with a period of snow melt and run off and continuing until the dramatic evacuation of the ice. This evacuation is dependent on the ice coverage of Lancaster Sound. The ice foot, a feature found often on arctic beaches was found to be larger in areas of more shallow sloping beaches. A sediment size analysis revealed a trend of diminuation of grain size from S. to N. reflecting net sediment transport in that direction. The two major geomorphic events of the 1971 open water, were two storms, both of which had winds from the S.E. that generated 1.0 meter waves which moved sediment from S. to N. The importance of a small pack of ice in the nearshore zone in inhibiting wave action was noted during one of these events. The freeze-up sequence progressed slowly after the advent of sub-freezing temperatures until the temperature of the seawater reached its freezing point, whereupon the rapid covering of the bay with ice ensued.</p> / Thesis / Master of Science (MSc)

This thesis examines a bayhead bar in the western end of the Lake Ontario Basin with the purpose of determining the dominant factors in the process-response model. From former field examination of the bar, and through the collection of deep drill cores, an attempt has been made to establish former processes which acted in the area of the present bar, Presently, field study, especially through the collecting of drill cores, sediment samples and wind data and by logging of wave data and longshore movement, has led to an attempt to establish the effect of present processes acting on the bar. / Thesis / Bachelor of Arts (BA)
