Campusbokhandeln : Investigation of a new Establishement

Henriksson, Björn, Frenzel, Felix January 2008 (has links)
In the majority of cases students are short of money and have problems to finance their low standard subsistence. An additional financial burden for students is purchasing the costly literature for their courses and studies. Universities often support their students by providing a library but a library can never cover all the books that are demanded. Students often do not need or use their purchased books longer than they have to; with the closure of a course or a semester books become useless for the owner. To get back some money after having used a book it is common to resell the book in various ways. Regularly students’ organisations or universities established some sort of platform for example a bill-board in their facilities or on the internet. But the existence of these platforms made trading the used literature not easier because there are no rules and no regulations. The store Campusbokhandeln took this problem and started a business to make it easier for students to sell and buy used books with fair regulations so every participator profits. Campusbokhandeln has a main store at Örebro University and one at Karlstad University. The purpose of the study is to find out whether Campusbokhandeln is able to expand their actions to another university in Sweden and if yes to which university. The results of the research show that the demand for a platform like Campusbokhandeln if very high and that the owners can take the chance to expand. After a SWOT-analysis we were able to point out chances and give suggestions about the future of the business.

Seasonal dynamics of planktonic pteropod assemblages in the waters of Liu-chiu Yu Island, Taiwan

Ko, Ju-hsuan 08 September 2010 (has links)
This study investigates the tempo-spatial distribution in species composition and abundance of planktonic pteropods in relation to hydrography in the waters around Liu-chiu Yu Island, southwestern Taiwan from February 2006 to October 2007. In total, we recognized 25 pteropod species belonging to 12 genera and six families, with a mean abundance of 7348 ¡Ó 994 ind./ 1000m3. The five most dominant species were Limacina inflata, Creseis virgula var. conica, Creseis acicula, Limacina trochiformis and Creseis clava, together they accounted for 78.7 % of the total pteropods. The surface sea water temperature, salinity, and phytoplankton concen- tration in the waters around Liu-chiu Yu Island were significantly higher in 2006 than in 2007. Pteropod abundance was higher in spring than in other seasons, and higher in deeper waters than in surface waters. Species number of pteropods was significantly higher in 2007 than in 2006, generally higher in summer and lower in autumn, and higher in deeper waters than in surface waters. Species diversity index of pteropods was generally higher in summer and lower in autumn. Cluster analysis of hydrography included 4 clusters (e.g., 2007 summer, summer and autumn, spring and winter, spring), the 2007 summer cluster was different from other seasons. Pteropod assemblage showed apparent difference between seasons, the variation of pteropod assemblages between stations in spring was higher than other seasons. Linear regression showed that the species number (p < 0.01) and diversity index (p < 0.05) were positively correlated with abundance of fish larvae. Abundance of most dominant species of pteropods was significantly and positively correlated with abundance of fish larvae (e.g., Limacina inflata; Creseis virgula var. conica and Limacina trochiformis) and significantly and negatively correlated with phytoplankton abundance (e.g., Limacina inflata, p < 0.001). In addition to the hydrographic factors, the distribution of pteropods might also be affected by predatory fish larvae and phytoplankton supplement.

Analysis of persistent organic pollutants in benthic fishes in the adjacent waters of Hsiao-Liu-Chiu,Taiwan

Wu, Meng-chung 26 December 2010 (has links)
Persistent organic pollutants (POPs) have attracted the attention of scientists because they have the following characteristics: long-distance transmission, persistence, bioaccumulation and chronic toxicity. Due to their high hydrophobicity, POPs are easily absorbed by the suspended particles in the marine environment. The suspended particles then settle into the soil may pass through the food chain, resulting in bioaccumulation and biomagnifications and causing potentially hazardous effects on the environment and human health. This study focuses on the analysis of the persistent organic pollutants in different parts of 10 kinds of benthic fishes, including the muscle and visceral mass, adjacent to Hsiao-Liu-Chiu. The samples were analyzed using accelerated solvent extraction (ASE), and alumina column purification. Fifteen polycyclic aromatic hydrocarbons (PAHs) were determined by using gas chromatograph / mass spectrometer (GC/MS). After florisil column purification, polychlorinated biphenyls (PCBs) and 18 organochlorine pesticides (OCPs) were determined by using gas chromatograph / electron-capture detector (GC/ECD). The results showed that the concentration of PAHs range from 15 to 195 ng/g dw, with low ringed (3 rings) PAHs at a higher proportion. Total PCB concentrations range from 16 to 237 ng/g dw. The content of PCBs in muscles mainly consists of low chlorine numbers (1 to 4 chloride) -based, and in visceral and eggs the chlorine number (6 and 7 chlorine) are higher. The concentrations of OCPs range from 13 to 127 ng/g dw. Among the hexachlorocyclohexane (HCH) series, £^-HCH has the highest proportion, indicating the continued use of Lidane in recent years. In addition to the variance in POP levels among different species of fishes, different tissues also have high variations in PAH, PCB and OCP levels.

Composition and Seasonal Variation of Chaetognaths in the Coastal Waters of Kaoshiung and Liu-chiu Yu Island

Wang, Kai-Tin 08 September 2000 (has links)
Abstract There are 22 species of chaetognaths belonging 11 genera and 4 families found in coastal waters around the Kaohsiung and Liuchiu Yu Island from March 1997 to February 1998. The average abundance of chaetognaths was 2527 ¡Ó1659 ind./100m3. The 5 most dominant species were Flaccisagitta enflata, Aidanosagitta crassa, Sagitta bipuncata, Ferosagitta ferox and Serratosagitta pacifica, and comprised > 95% of total chaetognaths. Fl. efnlata was the most common and abundance species, its number occupied 70% of total chaetognaths and occurred in every station. These dominant species showed significant seasonal succession, in that, Fl. Enflata could be found in all seasons, while S. bipuncata was found only in fall and winter. Most of chaetognaths found in this study were pelagic, tropical and temperate species, and most of them are widely distributed in the Pacific, the Atlantic and the Indian ocean (50% of total species), and in the Indian and the Pacific ocean (41% of total species). In terms of ecological distribution patterns, warm euryhaline species (i.e. Fl. Enflata and Fe. ferox), and warm hyperhaline species (i.e. S. bipuncata and Se. pacifica) dominated in this study areas. The abundance of chaetognaths was higher in fall (4721 ¡Ó8435 ind./100m3) and the lower in spring (1077 ¡Ó995 ind./100m3). The horizontal distribution of chaetognaths was apparently influenced by the runoff of Kaohsiung Habor and Kaoping River, and the peak abundance was usually found in the front of Kaoping river plume. Most chaetognaths (over 60% of total amount) were found in the surface waters (0-5 m), and its abundance abruptly decreased with depth. The scales of day/night vertical migration of chaetognaths were small (generally less than 50 m). Three types of vertical migration were distinguished in this study: Nocturnal migration (i.e. Fl. Enflata and Se. pacifica). Reverse migration (i.e. S. bipuncata ), and Non-migration (i.e. Fe. ferox). The vertical distribution and the distance of vertical migration of most chaetognaths, however, varied seasonally.

Modelling &amp; Control of a 3DOF Helicopter

Bodin, Erik, Stenholm, Fanny January 2015 (has links)
The scope of this report is the development of a mathematical model and a control system for a three degrees of freedom (3DOF) helicopter rig. This 3DOF-system offers a good simplification of a real world tandem helicopter for evaluating performanceof different automatic control principles. A mathematical model of the system is developed using free-body diagrams. This mathematical model is then linearized and a controller is developed by decoupling the system. Due to model imperfections external disturbances and similar effects integral action is added as well as feed-forward compensation to reduce nonlinear effects. After the controller has been decoupled the two different controllers are tuned. The Linear-Quadratic Regulator, described in section 3.6, is used for selectingstate-feedback gains. Due to the highly nonlinear nature of the system an Extended Kalman Filter is developed to estimate unmeasurable states. The model and controller is then implemented on the actual rig and evaluated. The results displayed that the elevation controller had good performance. The travel controller also showed good performance but not as good as the elevation controller. The main goal of this thesis was to develop a controller for the 3DOF helicopter system. The results clearly show that an LQR-controller is able to successfully control a system like this with decent performance characteristics despite the highly nonlinear system.

Fantastic dreams : William Liu and the origins and influence of protest against the White Australia Policy in the 20th century

Greene, Charlotte Jordon January 2005 (has links)
Doctor of Philosophy / The structure of this study of William Liu will closely reflect his ideas and the major historical influences in his life, and will span the period from 1893 through ninety years spent mainly in Sydney, ending in 1983, the year before the beginning of the attack on multiculturalism launched by the historian Geoffrey Blainey. The memorialisation of Liu in the post-Blainey “immigration debate” period will then be considered. The study will also reflect the changes in protest against racially discriminatory immigration policies in Australia, as Liu moved from a period in which his was an almost isolated critique to one in which he was able to embrace the ever-widening group of people opposed to the ‘White Australia Policy’. This process has not been fully examined, perhaps due to the fact that the protest often appeared to have little impact upon policy. But the way in which Liu and other protestors expressed their view of what Australia should be and how the ‘White Australia Policy’ affected this vision sheds a great deal of light on these periods in Australian history. The structure of this thesis around Liu’s life, beginning with a period in which the ‘White Australia Policy’ was widely accepted, and ending in a period in which multiculturalism was entrenched as official policy, emphasises the cultural shift which was brought about by decades of protest against the Anglo-conformist model of Australian identity

Dvakrát šest historií života v nesnázích: Shen Fu (1763-1825?) a Yang JIang (nar. 1911) / Six histories in two lifes in hardship: Shen Fu and Yang JIang

Bašová, Hana January 2016 (has links)
This paper focuses on comparison of two memoirs from different periods of Chinese history: Shěn Fù's Six Chapters of a Floating Life (turn of 18th and 19th century) and Yáng Jiàng's Six Chapters from a Cadre School (first published in 1981). Both memoirs are joined in intertextual relationship; Yáng Jiàng refers to Shěn Fù's text by both title and structure of her work, while Qián Zhōngshū, her well-known husband, presents in his preface Six Chapters of a Floating Life as a book he never liked. This paper examines message of these two memoirs by formal and thematic analysis of topics, genre characteristics and attitude toward life of both authors.
