The secret life of Bacillus anthracis
Bacillus anthracis is the causative agent of anthrax, a serious and globally distributed zoonosis affecting a wide range of wild and domestic animals, invariably also humans.
However, although known to humans since biblical times, much remains to be elucidated concerning the ecology and transmission of this bacterium. Of particular interest is the Bacillus anthracis spore, the uptake of which is the predominant way to contract anthrax and which is legendary for its resilience in the environment and thus crucial for persistence and spread of the disease. Hence, the aim of this study is to review the natural transmission of
Bacillus anthracis and investigate potential means by which soil persisting Bacillus anthracis spores reach concentrations sufficient to infect susceptible hosts. When reviewing the literature, three different theories can be distinguished. Firstly, ?the incubator area? hypothesis suggests that favourable soil factors, possibly in association with amoebas, may constitute an environment supporting repeated spore-bacterium-spore cycling, thus increasing the local amount of spores.
KB-ryggstödet : Vidareutveckling av ett justerbart ryggstöd för rullstolar
This master thesis is commissioned by Permobil AB. The report describes thoroughly the developing process of an adjustable backrest for wheelchairs. The target group for the backrest are people that suffer from scoliosis or other spinal diseases. Because of insufficient pressure distribution usage of traditional backrests is not an option for them.The current solution has got a frame that is made by several adjustable links that is held in place by friction. Between the links velcro tapes are attached that is adjusts the depth.

Personlighet och objektivitet inom revisionsarbete : Har revisorns personliga egenskaper inverkan på förmågan att stå emot extern manipulation?
Objectivity is often emphasized as one of the fundamental principles for the auditing profession and is also a requirement for preserving satisfactory professional practice. The multiple company scandals in the first decade of the 21st century have created distrust for auditors? capability to maintain objectivity. The purpose of this study is to contribute with a new way of thinking when it comes to the factors that affect objectivity. Earlier studies have indicated that personality factors may affect work performance in many different fields and this study is exploring the connection between separate personality factors, and the capability of less experienced auditors to maintain objectivity in the relationship with dominating and demanding clients.Data was collected through a survey that was divided into two separate parts where the first part measured the participant?s score on different personality factors, and the other part measured the participant?s score on perceived objectivity.
Tillfrisknande och användning av hästar med fång :
Laminitis has crippled horses through times and many cures have been used to
treat it. Since the Mechanism of the disease is yet not fully understood, treatments
are only ways to alleviate the pain and at best, slow down the pathological process
enough to make time for improvement. This paper is a retrospective study of 71
horses treated by a protocol at Hästsjukhuset Strömsholm. The protocol implies
three visits at zero, five and fifteen weeks. At each the horse is evaluated and
treated by a veterinarian.
Agentkostnader, ägande och utdelningar : en studie om sambandet mellan ägandet och utdelningar i Sverige
Background: Theoretical, it?s been questioned why dividends exists in companies based upon the fact that there is a separation between ownership and control. According to the agency theoretical perception, dividends is used as a manner to unify the interest of this separation, which in turn lower the agency cost, and increase the efficiency of companies.Purpose: The aim of this master thesis is to scrutinize and analyse the association between Swedish firms? owner structure and owner types and their inclination to dividend.Method: We attack the problem with a hypothetical-deductive research method by using the existence of a universal theory, the agency theory. From our theoretical framework we propose a set of hypotheses.
Kalkningens påverkan på fosforlöslighet : skakförsök baserade på två svenska långliggande kalk- och fosforgödslingsförsök
Eutrophication is an environmental problem that affects more than ten percent of Swedish lakes. Excess nutrients increase the growth of algae, and cause major problems in the ecosystem through oxygen-free bottoms, fish kills, and at worst dead bottoms. Agriculture accounts for 44% of human emissions of phosphorus to lakes and rivers. Leaching occurs of particle bound phosphorus and of dissolved
phosphate. The amount of phosphate in the soil solution that may be leached is partly due to the prevailing pH in the soil solution.
The purpose of this study was to investigate how the relationship between phosphate solubility and pH was affected by liming.

Det gemensamma bästa kan inte förutsättas : En berättelse om Grupptalan mot Skandia
The subject for this paper is the Class Action against Skandia Association, a civil organization formed in 2003 with the aim of claiming compensation for some 1.2 million life insurance customers. The background to its formation was one of the largest financial scandals in Sweden in recent times, involving a number of questionable affairs within the insurance corporation Skandia and its subsidiaries, most notably the life insurance company Skandia Liv. The interests of both the stake- and stockholders of the company seem, in certain ways, to have been grossly misrepresented. The scandal, as well as the reaction it spawned, pose a number of questions. In this study, we focus on two: a possible, and in many ways apparent crisis in the representation of interests in Swedish society, and the role of civil society in upholding the balance between these interests.We argue that what is often held to be the ?greed? or ?immorality? of individuals in scandals such as Skandia is, to a great extent, a mere reflection of the ?rational? underpinnings of modern-day capitalism.We find that trust has been a key Mechanism of control in the relationships between consumers and agents in pension and life insurance markets, and that ?the Swedish model? that distinguished post-WWII Swedish society was a model heavily based on trust towards existing models of bureaucratic governance.
Mineraliska material som reaktiva filter för avskiljning av tungmetaller från dagvatten
Highly polluted urban storm water from e.g. highways can contain large amounts of heavy metals that may cause harm if they are discharged into recipients. To remove the heavy metals a possible low-cost method that does not require much maintenance, could be the use of reactive filters with filter materials consisting of industrial residues or other cheap mineral based materials. Dissolved metal ions are removed by reactive filters through the processes of ions binding to active sites on the surface of the filter materials, or by formation of insoluble precipitates.The ability of CaO-treated granulated blast-furnace slag, iron oxide coated sand, olivine and nepheline to remove seven heavy metals (Cr, Cd, Cu, Ni, Zn, Pb and Hg) from urban storm water was studied. Initially batch experiments were performed where the effect of pH, dissolved organic carbon (DOC) and dissolved ions on the adsorption efficiency was studied.
Avgång av lustgas från luftningsprocessen på Käppalaverket
The requirements for wastewater treatment plants (WWTP) are gradually increasing, partly because of higher incoming loads, which in turn require a more efficient treatment process. In parallel with environmental and economic goals there are also desires to lower energy consumption without compromising the wastewater treatment. Furthermore, there is a demand on WWTP´s to alter eutrophication in aquatic systems through better nitrogen and phosphorus removal. An increasing number of WWTP´s have acquired biological nitrogen and phos-phorus removal. A by-product of this type of biological treatment is the formation of nitrous oxide, which is a potent greenhouse gas.

Djuromvårdnad vid fång
Laminitis is a common but devastating condition, and affected horses are often euthanized or influenced a very long time. Many horses never return to their original capacity. Laminitis is often associated with severe pain and a long time of convalescence. Symthoms includes lameness, hoof hyperthermia, strenghthened digital pulse and pain. The horse often tries to move the body weight away from the forelegs which are often more severly affected than the hindlimbs.
