Presented work is directed to summarize the results of ochtyomonitoring of five stream in Bohemian Forest in autumn 2010. The processing status is evaluated fish communities, especially their species composition, diversity, dominance, evenness and other parameters. They have been evaluated also physico-chemical properties of the sites such as air and water temperature, conductivity and turbidity. Last but not least were evaluated the characteristics of flows and in particular morphological characteristics, types of the bottom substrate and its contours etc. The evaluation of all obtained data showed that fish communities surveyed Bohemian flows are balanced, they are not burdened with invasive species and rand indicators correlated with the state of flow, geographic location and natural conditions. It was caught nine fish species in the total number of 963 individuals. Abundance was at all locations in the range 201,6 to 409,7 individuals per kilometer of flow, showed the diversity of communities from 0,372093 to 2,166085 (Shannon and Wiener index) and from 0,301804 to 0,866948 (Simpson index), then evenness of plant 0,372093 to 0,783906. The most dominant species was the brown trout, the second most frequent species was bullhead.

Conselho Nacional de Desenvolvimento Científico e Tecnológico / Understanding the dynamics of vegetation could facilitate decision making and adoption of new management practices, seeking a better use of available resources in areas of natural grassland. This study aimed to evaluate the dynamics of a natural grassland vegetation subject to grazing and fertilization, in four different locations in the counties of Pinheiro Machado and Piratini, located in the upper basin region of Rio Camaquã. The treatments were a combination of the above factors. The estimation of species composition and biomass followed BOTANAL field method procedures, with some adjustments. There was a change in vegetation dynamics in the treatments as a response of the interaction of evaluation period, fertilization and grazing, showing a divergence of the trajectories of vegetation and there is no clear distinction of functional types. There was not a clear association between the functional types and environmental variables. The diversity and evenness of species were quantified using the Shannon and equitability indexes. There were no significant differences between different fertilization, but for grazing, there was a significant difference between the evaluation periods. Areas subjected to controlled grazing, show a tendency to increase the diversity of species compared to areas subjected to continuous grazing. The use of controlled grazing had a positive influence on species diversity. / A compreensão da dinâmica vegetacional pode facilitar as tomadas de decisões a adoção de novas práticas de manejo, visando um melhor aproveitamento dos recursos disponíveis em áreas de pastagem natural. Este estudo teve como objetivo avaliar a dinâmica vegetacional de uma pastagem natural submetida aos fatores adubação e pastejo, em quatro locais diferentes, nos municípios de Pinheiro Machado e Piratini, localizados no terço superior da bacia região do Rio Camaquã. Os tratamentos foram constituídos pela associação dos fatores acima. As estimativas da composição de espécies e suas respectivas biomassas seguiram os procedimentos de campo do método BOTANAL, com algumas adaptações. Visando gerar hipóteses sobre os efeitos dos tratamentos, foram utilizadas análises multivariadas para os dados de dinâmica de espécies e tipos funcionais. A diversidade e uniformidade de espécies foram quantificadas através dos índices de Shannon e da equitabilidade. Houve uma mudança na dinâmica vegetacional em função dos efeitos compostos pelos fatores períodos de avaliação, adubação e pastoreio, indicada por uma divergência nas trajetórias da vegetação. Não foi evidenciada uma associação nítida entre os tipos funcionais e as variáveis ambientais. A diversidade e uniformidade de espécies foram quantificadas através dos índices de Shannon e da equitabilidade. Não foram observadas diferenças significativas entre as diferentes adubações, para o pastejo, houve diferença significativa na comparação entre os períodos de avaliação. Áreas submetidas a pastoreio controlado demonstraram uma tendência ao aumento da diversidade de espécies, quando comparadas a áreas submetidas a pastoreio contínuo e sem controle que apresentaram valores menores.

Thesis (M.Sc. Agriculture (Pasture Science)) -- University of Limpopo, 2021 / Savanna rangelands are ecosystems which are characterized by the co-existence of scattered trees and shrubs with a continuous grass layer. However, the grass and tree balance has been highly altered as a result of disturbances caused by bush encroachment. Encroaching woody species have been shown to decrease species richness and abundance of the seed bank and ground‐layer diversity. So far little is known on the effect of bush encroachment and soil depth on the soil seed bank diversity in savanna rangelands. The objectives of this mini-dissertation were to (1) determine the influence of soil depth on soil seed bank diversity in bush encroached savanna rangelands, and (2) determine the relationships between soil seed bank herbaceous vegetation and physicochemical properties in encroached rangeland. In order to address these objectives, a savanna rangeland was demarcated into two encroachment gradients spanning from open to encroached rangeland. Within each encroachment gradient, six plots of 10 m x 10 m were randomly selected, whereby soil sampling and herbaceous vegetation were carried out and determined. In each replicate plot per encroachment level, five soil samples were randomly collected at 0-10 and 10-20 cm depths. The number of seedlings of different species emerging from the soil samples was used as a measure of the number of viable seeds in the soil and the composition of the seed bank using the seedling emergence method. The total seed densities showed significant differences (P<0.05) in the 0-10 cm depth layer in the open rangeland and encroached rangeland. Bush encroachment significantly (P<0.05) decreased the seed density of perennial grasses, specifically in 0-10 cm depth layer. Further, species diversity increased with bush encroachment in the 10-20 cm depth layer. Menhinick’s richness index showed no significant difference in the open and encroached rangeland, while species evenness decreased in the 0-10 cm depth layer and increased at 10-20 cm depth.The study also revealed negative correlations between organic carbon, calcium, clay, silt and forbs while mean weight diameter (MWD), a measure of soil aggregate stability was positively correlated with forbs. The canonical correspondence analysis (CCA) showed that pH, phosphorus, potassium and calcium were positively correlated to Eragrostis curvula and magnesium was negatively correlated to Panicum maximum. In open rangeland, CCA revealed that clay content was negatively correlated with species evenness while xii magnesium was negatively correlated to the Shannon Weiner index. Further, silt content was positively correlated with species richness and evenness. In the encroached rangeland, the CCA showed a negative correlation between magnesium and the Shannon Weiner index. The Sørensen’s index between soil seed banks and aboveground vegetation was low with index values of 0.22 and 0.24 in open and encroached rangeland, respectively. / AgriSeta

The thesis is focused on the problems of illumination of interior space, especially in object in Moravský Písek. The thesis is divided into two parts, where the first part deals in general with the basic quantities and terms which are used in illumination systems. Further, it is about general properties of lights and about general terms of illumination of interiors. The second part is only practical character. At the beginning, there is used manual measurement and modelling to evaluate initial state in program Relux. The measurement is not met in terms of standards. Thanks to the municipal council of Moravský Písek a new lighting system is created, which fully respects the valid normative regulations. Installation of control system of lighting is integrated to proposal, which would result in lower consumption, greater user comfort and greater versatility in the possible use of the object. In the end, there is financial evaluation of illuminating system and comparison classical with led technology.

A smooth surface with good friction on the cycle path is not only important for the traffic safety of the cyclists but also for their comfort and level of service. Potholes, cracks, and bumps are frequent obstructions on the cycle paths. These are all maintenance-related deficiencies associated with the degradation of the structure. In general, the knowledge on degradation of roads is good, as there is a long tradition of investigation into the degradation factors. Cycle paths, even though constructed with similar materials and techniques as the roads, are however not designed in the same way as roads, mainly since they will not be subjected to the same traffic load. Thus, one purpose of this licentiate thesis is to identify degradation factors specific for cycle paths, through a state-of-the-art literature study. The literature review is complemented by two papers, where Paper A analyses the distress found on Swedish municipal cycle paths and Paper B evaluates a novel method for condition assessments on cycle paths related to cycling comfort—the Bicycle Measurement Trailer. The review and papers are meant to act as the basis for the general aim of the PhD-project, namely, to develop more knowledge on the degradation of cycle paths. This knowledge is needed to improve the structural design approaches and maintenance strategies for cycle paths and to give guidance for preventive measures to inhibit degradation. / En slät yta, med god friktion, på cykelbanan är inte bara viktig för cyklisternas trafiksäkerhet, utan för deras komfort och framkomlighet. Potthål, sprickor och ojämnheter är vanliga hinder på cykelvägarna. Dessa underhållsrelaterade brister är direkt kopplade till nedbrytningen av cykelvägarna. Generellt sett är kunskapen om nedbrytning av vägar god då det finns en lång tradition av forskning kring nedbrytningsprocesserna. Cykelvägar, även om de är byggda med liknande material och tekniker som vägarna, är dock inte dimensionerade på samma sätt som vägar då de inte utsätts för samma trafikbelastning. Ett syfte med denna licentiatuppsats är således att identifiera nedbrytningsfaktorer som är specifika för cykelvägar. En ”state-of-the-art” litteraturstudie kompletteras av två artiklar, där Paper A analyserar de skador som återfinns på svenska kommunala cykelvägar och Paper B utvärderar en ny metod, Cykelmätvagnen, för tillståndsbedömningar på cykelvägar, relaterat till cykelkomfort. Litteraturstudien och artiklarna är tänkta att ligga till grund för doktorandprojektets övergripande syfte, nämligen att utveckla mer kunskap om cykelvägars nedbrytning. Denna kunskap behövs för att förbättra de strukturella dimensioneringsprinciperna och underhållsstrategierna för cykelvägar och ge vägledning för förebyggande åtgärder som motverkar deras nedbrytning.

It is well established that national retail chains impact small, single location retail businesses in terms of revenue generation, retail structure, retail type diversity, and location. This study examines the retail structure and diversity of five retail districts in the City of Denton, Texas. The analysis focuses on one central business district (CBD), one traditional retail strip center (University Drive, also known as US HWY 380), one special retail district (Fry Street District), one traditional enclosed shopping mall and associated development (Golden Triangle Mall), and one power retail center (Denton Crossing). The empirical foundation for the investigation is a historical business database covering years 1997 to 2010, obtained from Info Group's Reference USA. This Reference USA database includes location, industry, and status (single versus chain location) information for each business. Retail diversity and evenness were measured for each of the five retail districts using the Simpson's Diversity Index and the Simpsons Measure of Evenness, leading to specification of the differences that exist in retail structure and diversity among the districts. Golden Triangle Mall and Denton Crossing were primarily chain location in composition while Fry Street District, the CBD, and University Drive were primarily single location in composition. Across all years, the single versus chain status of the local business communities did not substantially change within any of the districts. The Fry Street District exhibited the most change in diversity as well as the lowest overall diversity among the retail districts, followed by University Drive and Golden Triangle Mall. The CBD did not experience any major change in retail type diversity. However, all retail districts experienced major changes in retail evenness. Overall for the city, single location retail businesses accounted for the majority of all the retail businesses, however, chain locations employed more people. In total, these findings indicate that the development of retail districts composed primarily of chain location retailer's affects retail district diversity and evenness but not retail structure.

The fundamental research work about the superconducting magnetic bearing (SMB) twisting system provides huge potential to eliminate the most important limitation of productivity, that is, the friction in the ring traveler system of the existing ring spinning process. As a continuity of the research work, the functionality of the SMB spinning has been carried out with different angular spindle speeds, yarn counts, and materials in order to determine the influence of the SMB technology. The current paper presents a comparative investigation of the yarn properties, such as yarn tenacity, yarn elongation, yarn evenness, microscopic views, etc., between conventional and SMB ring spun yarn. The intensive analysis confirms that the SMB system enables one to produce satisfactory yarn quality similar to that of conventional ring spun yarn up to 15,000 rpm. The influence of conventional and SMB spinning processes on yarn properties has been further analyzed statistically using an analysis of variance.
