Makurath (1977), in studying the Keyser Limestone, concluded that brachiopods were distributed randomly, casting doubt over the validity of using recurrent communities as a paleoenvironmental tool. However, a re-evaluation of the Keyser fauna, utilizing cluster analysis, polar ordination, and detrended correspondence analysis, reveals that the fauna can be arranged along a gradient, according to distance from the shore. Recurrent communities do exist within the Keyser Limestone. With the aid of coenocorrelation curves, they can be traced along the entire Appalachian basin. The most nearshore community, belonging to Benthic Assemblage 1 of Boucot (1975), is the Stromatolite Community, followed by the Tentaculites-Meristella-Cupularostrumgordoni Schuchertella and Meristella Communities of Benthic Assemblage 2, the Stromatoporoid-Coral, Crinoid, and Gypidula communities of Benthic Assemblage 3, the Dalejina -Atrypa-Rhynchospirina Community of Benthic Assemblage 4, and the Eccentricosta-Cupularostrum Assemblage 5. / M.S.

This paper shows the results of asurvey on use of traditional medicinal plants of K’ho people who living in the buffer zone of Chu Yang Sin National Park, Central Highlands, Vietnam. Total of 66 medicinal plant species belonging to 61 genera, 40 families were recorded through semi-structured interviews, group discussions and from guides of field trips who are knowledgeable about medicinal plants. These medicinal plants used by K’ho people are documented with latin name, family, local name, parts used and medicinal uses. In generally, fresh medicinal plants are mainly boiled or decocted for drinking and leaves are parts most commonly used. The results of this study showed that K’ho people still depend heavily on medicinal plants to treat diseases such as headache, fever, malaria, diarrhea, fractures, sprains and arthritis. / Bài báo này đề cập kết quả khảo sát cách sử dụng cây thuốc truyền thống của người K’ho sống ở vùng đệm Vườn quốc gia Chư Yang Sin, Việt Nam. Tổng số 66 loài cây thuốc thuộc 61 chi, 40 họ đã được ghi nhận thông qua quá trình phỏng vấn bán cấu trúc, thảo luận nhóm và từ những người dẫn đường đi thu mẫu có am hiểu về cây thuốc. Những cây thuốc truyền thống của dân tộc K’ho được tư liệu hóa gồm tên latin, tên phổ thông, bộ phận sử dụng và cộng dụng. Nhìn chung, dược liệu tươi được dùng đun hoặc sắc để uống là chủ yếu và lá là bộ phận được sử dụng phổ biến nhất. Kết quả nghiên cứu cho thấy cộng đồng K’ho vẫn phụ thuộc vào cây thuốc để chữa trị một số bệnh như đâu đầu, sốt, sốt rét, ỉa chảy, lị, gãy xương, bong gân và thấp khớp.

Ethiopia like other developing countries depends on domestic agricultural production, struggling with infrastructure and healthcare is also at a low level. Among these factors there is also added impact of catastrophic natural processes. Landslides in this area have caused enormous material damage and also human deaths. Effects of those losses are huge and locals are dealing with them difficuly. Therefore, prevention should be a priority concern. In theoretical part the basic facts about modeling and simulation of landslides susceptibility is presented. Those facts are complemented with specific researches from Ethiopian highlands. Furthermore, it describes the methodology that was used. It compares the real distribution of slope movements against the expected occurrence across the classes of input layers. An essential part of the model is mapping work, supported with terrain work, during which 242 landslides was mapped. Model parameters are: slope, altitude, lithology, land cover, distance from geological boundary and distance to river. Slope was determined as most significant factor. Used methodology is universally applicable and the results it generates match reality well. Key words: slope movements, natural hazards, susceptibility analysis, geomorphology, Ethiopian Highland

Master of Science / Department of Plant Pathology / Karen A. Garrett / Ari Jumpponen / Traditional fallow periods in the Bolivian highlands are being shortened in an effort to increase short-term crop yields, with potential long-term impacts on soil communities. Using 454-pyrosequencing, we characterized fungal and bacterial community responses to (1) the length of fallow period and (2) the presence of the plants Parasthrephia sp. or Baccharis sp. (both locally known as ‘thola’). Thola is widely considered by farmers as beneficial to soil health, although it is also frequently harvested as a source of fuel by farmers. Soils in one study area, Ancoraimes, had higher levels of organic matter, nitrogen and other macronutrients compared to the other study area, Umala. In our analyses, Ancoraimes soils supported more diverse fungal communities, whereas Umala had more diverse bacterial communities. Unexpectedly, the longer fallow periods were associated with lower fungal diversity in Umala and lower bacterial diversity in Ancoraimes. Fungi assigned to genera Verticillium, Didymella, and Alternaria, and bacteria assigned to genera Paenibacillus, Segetibacter, and Bacillariophyta decreased in abundance with longer fallow period. The presence of thola did not significantly affect overall soil fungal or bacterial diversity, but did increase the frequency of some genera such as Fusarium and Bradyrhizobium. Our results suggest that fallow period has a range of effects on microbial communities, and that the removal of thola from the fields impacts the dynamics of the soil microbial communities.

The presented PhD thesis deals with present-day geodynamic processes in the south- western part of Broumov Highland, with a special attention paid to the seismoactive Hronov- Poříčí Fault Zone (HPFZ). Compared to the rest of the Bohemian Massif the studied area exhibits relatively increased level of tectonic activity, which is evidenced by local seismicity and by presence of CO2-rich mineral waters. The present-day activity of geodynamic processes is studied by means of various geomorphological, geotechnical, geophysical and hydrological methods. Following processes and features were studied: activity of slope movements, seismic activity, present-day tectonic movements, relations between landforms and joint and fault tectonics. Based on the previous experience obtained by the author in the seismoactive area of Western Bohemia, groundwater observational network was set up in deep boreholes, in order to detect anomalies related to the tectonic activity of the studied area. The thesis represents a contribution to the deeper understanding of the studied area and also a contribution in respect of possible applications of some new methods that can be used in research of zones with relatively increased tectonic activity inside of stable areas of Central Europe. From geomorphological point of view, the...

<p>Highland Group AB was helping a customer of theirs to create an All-Terrain Vehicle (ATV), a project Highland has never been involved with before. For the wishbone arms of the wheel suspension, traditional manufacturing methods and tubes with cylindrical or square shaped cross section was preferred. We performed a simulation where the ATV was driving on a bumpy road too see the forces involved. With the results we proceeded to calculate the strength of the concepts to find out which is best suited for the tough environment in which the ATV is used. The concept that turned out to be the best was a wishbone made of circular cross section, which had good structural strength and did fulfill the demands that we required for the construction. The company where interested in the project and could see themselves proceeding with the work in the future. We helped the company to find interest for computer aided simulation in collaboration with structural strength analysis, which they would like to engage in. The project has given us a larger knowledge in the choices of construction and structural strength analysis as well as experience working with computer aided construction tools.</p>
