Suitability analysis of a reintroduction of the great bustard (Otis tarda) to Sweden

The great bustard (Otis tarda) became extinct in Sweden during the mid-19th century. Globally, populations have suffered dramatic declines during the past two centuries. Recently, local populations have stabilized or increased after hunting bans and conservation efforts. Despite positive trends the species is still classified by IUCN as vulnerable (VU), mainly due to withdrawals in the distribution. The limited distribution emphasizes the need for finding ?new? areas suitable for a translocation or reintroduction.

Avena Sativa - En hyperackumulator? : En studie av havres kadmiumupptag

The aim of our research was to investigate if oat is capable of extracting cadmium to such extent that it is usable in decontaminating polluted soils. We grew oat in a hydroponic culture during 28 days in a controlled environment and a total of 30 plants were used. The nutrient solutions were contaminated with cadmium of ten different concentrations after seven days. After harvesting the plants, the roots were separated from the shoots, placed in separate containers and then turned to ashes. The cadmium content was measured three times per sample in an atomic absorption spectrometer.Our results indicate that the ability of oat to extract cadmium from a solution is linearly dependent of the cadmium concentration of the solution.

Below-the-line : En fallstudie av små företags tillämpning av marknadskommunikation med fokus på below-the-line metoder

This study aims to research how small companies that operate on the Swedish home electronic-market utilize marketing communications to communicate their message. The focus of this study has been to research these companies use of below-the-line activities in their marketing communications. Interviews have been conducted with representatives from each of the three companies Neonode, Jens of Sweden and Tonium, that compose the selection from the population in this study. The use of below-the-line activities in small companies is mainly motivated by lower cost, which suit small company budgets. Below-the-line activities are also used for branding and the creation of credibility among the consumers when the target audience does not yet know the brand.

Debuten av gluten ? Har tidpunkt för glutenintroduktion någon betydelse för risken att utveckla celiaki hos högriskbarn?

AbstractTitle: The debut of gluten ? Does timing of gluten introduction affect the risk ofceliac disease in high-risk children?Author: Sandra Hagwall Frohm and Maria IngmarSupervisor: Frode SlindeExaminer: Mette AxelsenProgramme: Programme in dietetics, 180/240 ECTSType of paper: Bachelor?s thesis in clinical nutrition, 15 hpDate: May 26, 2015Background: Celiac disease is a chronic disease in which the intestinal mucosa is damaged bygluten exposure, and the only treatment is a lifelong gluten-free diet. The disease affects about1 % of the population worldwide, but the majority are undiagnosed. Ingestion of gluten and thegenotype HLA-DQ2/8 are required for disease development, although additional genetic andenvironmental factors are believed to be of importance. One hypothesis is that timing of glutenintroduction in infants affects the disease risk.

Konstruktionen av den japanska ledaren: En studie av kvinnans roll i det japanska företaget

Japan is the first industrialized country that is experiencing the threat of a rapidly declining and aging population. This has shifted the focus and the limelight is now on the matter that for a long time has been ignored. That is, the Japanese women?s situation in the society. This thesis seeks to point out the relevance of gender in the construction of leadership in order to get a deeper understanding of the Japanese women?s situation today.

Lönsamheten vid nystart av slaktsvinsproduktion : en fallstudie

I have done a case-study about building a new stable for slaughter pigs at a farm close to Kalmar. The farm is able to supply the breeding with cereals and it has enough area to spread the manure on. The most important factors to gain profit, is the cost for building the stable, the price of the feeding-stuff and the growth of the pigs. The discount from the slaughter-house was less important than I thought from the beginning, and it?s a factor that is hard to influence. With the new production of slaughter-pig and cattle that already exist on the farm, the farm will get a well-functioned rotation of crops with lye and autumn rape as interruption-crop.

Evolution av målsökande och flyende boids

Detta arbete använder genetiska algoritmer för att få fram ANN hos boids utifrån två uppsättningar regler och jämför de resulterande beteendena med varandra. Boids är simulerade fåglar i en fågelflock som var för sig styrs med enkla regler men som tillsammans bildar ett flockbeteende. Genetiska algoritmer liknar naturens evolution. En population vars egenskaper kodas på ett genom blir bättre på de egenskaperna genom att de bästa individerna väljs ut och får utvecklas mer medans de sämre rensas bort. ANN står för artificiella neurala närvek och ska likna biologiska neurala nätverk och ska med andra ord fungera som en hjärna.

Presterar Hedgefonder bättre än traditionellt förvaltade fonder?

Hedge funds have the past few years become an increasingly popular investment alternative and in the last decade hedge fund assets managed have quadrupled to USD 2000 billion, a growth rate of around 25-30% per year. One explanation for this substantial increase is that hedge funds' minimum limits on capital invested has declined, which have made ??them available to retail investors. The recent turmoil in financial markets has also contributed to investors finding their way to hedge funds, whose goal is to generate stable returns regardless of how the market develops.Using Sharpe?s, Treynor?s and Jensen's performance measures, I have investigated whether hedge funds manage to generate higher risk-adjusted returns than traditional managed funds.

Förändrat uttryck av Epidermal Growth Factor Receptors ligander i androgenoberoende prostata-cancer

Denna studie undersöker hur stressfaktorer påverkar kroppen vid dykning i gruva. Undersökningen genomfördes under en helgs intensivt dykande, för att bestämma lungkapacitet, pulsnivå samt eventuell vätske- och viktförlust hos dykarna. Testerna bestod av vägning, spirometritester och pulsmätningar. Testpersonerna dök mellan ett till tre dyk under helgen. Två av det totala antalet dyk var på 74 meters djup, resterande dyk genomfördes på 36 meters djup.

Läs- och skrivinlärning : Om elevers läs- och skrivinlärning under de första åren

In contemporary Sweden political participation among foreign-born Swedes is viewed as low and it is well known that foreign-born individuals do not use their voting rights to the same extent as the general population. At the same time there are numerous ethnic associations around the country who work with various activities involving political, democratic and integration issues. This study aims to study how four members of a Somali association regard, relate to and work with politics, democracy and integration. The study is based on these four people, but also on their relationship with authorities and other agencies in the community. The conclusion of this study shows in brief that the desire to participate politically is great, but that democracy and politics is accessible to all, depending on the level of language skills and what political knowledge the individual has.

Digital kontra manuell blodtrycksmätning-Är resultaten samstämmiga?

Blodtrycksmätning är en viktig del i en sjuksköterskas arbetsuppgifter och då både manuell och digital blodtrycksmätning idag förekommer parallellt inom svensk sjukvård syftar denna studie till att undersöka om det finns någon skillnad mellan de uppmätta resultaten i dessa mätmetoder och beskriva denna eventuella skillnad. Undersökningen genomfördes på en kärlkirurgisk avdelning på ett sjukhus i södra Sverige under hösten 2009. Populationen bestod av 38 inneliggande patienter som följdes upp med totalt 65 blodtrycksmätningar. För att utföra undersökningen tillämpades cross-over design med kvantitativ ansats. Resultaten visade skillnader mellan de två mätmetoderna då den digitala metoden uppmätte högre blodtryck än den manuella. Digital blodtrycksmätning visade genomgående högre mätresultat jämfört med manuell metod.

Mastcellens funktion vid försvar mot infektioner

The complexity of the mast cell is becoming more prominent. From being the cell recognized just to contribute to allergic inflammation it is now also associated with wound healing, protection against tumor growth and in recognition and defense against a wide range of pathogens. The location of the mast cell in the barrier between the external and internal environment of the body enables the cell to quickly respond to invading bacteria, virus and parasites. Diarrhea due to Escherichia coli infection, listeriosis, toxoplasmosis, Newcastle disease and bovine respiratory syncytial virus are examples of mast cell activating diseases that can affect animals in, as well as outside, the agricultural sector. Additionally, ticks and tick-borne diseases are of concern.

Visioner om framtidens profilboenden : Hur äldre personer vill bo när det bli ännu äldre

As the population of senior citizens increase, various housing options are required for an increasing competitive environment within elderly care. This study addresses the concept of profile housing for the elderly by outlining its definition and providing options for the different kinds of housing options available within the municipalities of Stockholm and Solna. The study reveals that these locations have different definitions of what constitutes a profile home. Based on this, should one assume there are further definitions to cover additional municipalities?     This study also touches upon how a group of senior citizens would perceive their living conditions if relocated into such housing. Members of the group have also expressed that they would like to go about their daily activities as they have prior to being relocated. They want health professionals to enable and encourage participation in various daily activities..
