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.

Governance Disclosures According to IIRC's Integrated Reporting Framework -Are Annual Reports of Swedish Listed Companies in Line with the Framework?

Background and problem - Integrated reporting is a hot topic today and is predicted to be the future of companies? external reporting.

Du slåss ju som en hel karl, tjejen! Tankar om kickboxning i skolan som en väg till att nå ökad jämställdhet

The purpose of this thesis is to, based on interviews and document studies, critically discuss how the introduction of kickboxing in Physical Education (PE) could affect gender equality in society. Based on a queer feminist and norm critical perspective on the prevailing teaching of PE, which, despite official efforts to challenge and modernize PE, persists in reproducing gender norms by e.g. spending 75% of class time on ball games. The hypothesis is that girls accessing violence (empowerment) through a bodily awareness in the form of kickboxing, positively would challenge the power imbalance that gender norms create. Girls are brought up, even today, in accordance with gender norms arguing against girls/women wanting to use their bodies as powerful tools to set limits.

Större och mindre växtätares samexistens : Möjlig interaktion och effekt på lokal biodiversitet

The purpose of this report was to investigate to which extent local presence of large herbivore mammals (Alces alces, Cervus elaphus, Capreolus capreolus, Dama dama and Sus scrofa) covaries with small rodents (Myodes glaerolus, Apodemus flavicollis and Apodemus sylvaticus? The hypothesis was that high abundance of wild ungulates would inhibit the density of small forest rodents. The data was collected during field work within FoMA (Environmental Monitoring Assessment)/SLU (Swedish University of Agricultural Science). The Ungulate dropping inventory and rodent trappings, which is the base in this report, where performed 2012 ? 2014 in Gnesta/Nyköping municipalities (G/N) with a relatively high density of wild ungulates and Vetlanda/Växjö municipalities (V/V) with relatively lower wild ungulate density.

Volymsrapportering vid terrängtransport av virke

H?RNERVMOSSA I SANDSJ?BACKA NATURRESERVAT: Analys av h?rnervmossans invasivitet p? ljunghedens vegetationstyper

Heath star moss (Campylopus introflexus) is an alien species in Sweden and is currently classified as composing a "very high risk? of becoming invasive in the country according to SLU, and has in several parts of the world taken over large areas in a short time. The moss is characterized by its preference for disturbed and burned land, something that occurs on the heathland in the Sandsj?backa nature reserve, when burning for nature conservation purposes is carried out annually. Sandsj?backa's heathland is a valuable ecosystem and is one of the few heathlands in a favorable condition that remains in Sweden after strong reforms in modern agriculture in the last century, which led to forest succession of these cultural environments.

Köper studenten köprekommendationen? : En studie om aktierekommendationer

Bakgrund: Aktierekommendationer är vanligt förekommande i finansiell media samtidigt som teorier säger att man inte systematiskt kan över- eller undervärdera en aktie. Trots detta visar studier att finansmarknaden influeras av aktierekommendationer då handeln ökar efter en annonsering, vilket innebär att de finansiella kunskaperna en student har lärt sig under sin utbildning inte påverkar lika starkt när den sedan väljer att följa en aktierekommendation.Syfte: Syftet med denna studie är att undersöka vilka faktorer som påverkar ekonomistudenters uppfattning av aktierekommendationer och hur stor påverkan valet av utbildningslinje har för hur studenten bedömer aktierekommendationer.Referensram: Referensramen kommer ge en förförståelse samt behandla de teorier som är väsentliga för att utreda studien. Referensramen innefattar prisbildning, EMH, behavioural finance, risk, kulturella influenser, utbildningens influenser och skolornas bakgrund.Metod: För att bäst kunna besvara och undersöka syftet genomförs studien som en förklarande surveyundersökning med en kvantitativ ansats. Undersökningen utförs genom en elektronisk enkät som skickas ut till studenter.Empiri: Det empiriska materialet består av enkätsvar från studenter från fyra olika ekonomiska utbildningslinjer som bearbetats med stistiska metoder.Slutsats: Valet av utbildningslinje påverkar studentens uppfattning om aktierekommendationer. De faktorer som påverkar är tron på den effektiva marknadshypotesen, studentens finansiella intresse, kön, riskbenägenhet, teoretisk kunskap samt kultur.

Fine-Mapping of Equine Multiple Congenital Ocular Anomalies on horse chromosome 6

Multiple Congenital Ocular Anomalities (MCOA) is a genetic disease that affects primarily Silver coloured horses of breeds such as the Rocky and Kentucky mountain horses. In these breeds the Silver dapple colour is very popular leading to an increase of affected horses. The major feature of the disease is ocular cysts of variable size. Large cysts also lead to a variety of secondary syndromes, for example retinal detachment. In previous studies the locus for MCOA has been mapped to an interval of 420 kb on equine chromosome six.

Vad påverkar en aktieanalystillförlitlighet? : En kvantitativ studie om relationen mellan tillförlitligheteni en aktieanalys och dess innehåll.

A debate in finance is whether a random investment gives the same return as carefully choose and valuing an amount of shares to invest in. Stock valuating Stock valuation is often done by fundamental valuation models, based on the company's underlying character, which tries to put a correct price on the stock. Today there are several different valuation models that can be used for this purpose. Since valuation models are only mathematical, equity research is underpinned by more subjective assessments about the company and its future.The purpose with this thesis is to describe which valuation models that are used by professional stock analysts, but also to see if the reliability on the equity research is affected by the used model to valuing the company. Furthermore, we want to see if the job that?s been done to understand the company, measured by the equity research quality, impact the reliability on the equity research.In this thesis, we have, to achieve our purpose, conducted a quantitative content analysis of 164 equity research done by professional analysts at firms listed on the Stockholm Stock Exchange. With basis in previous research, we have developed a method for determining the valuation model that is used in the equity research, the reliability on the equity research and a framework for assessing the quality of the equity research.In the theoretical framework the valuation models involved in our study are described, previous research on the reliability on the equity research and their practical use.

Påskön. Myten om Rapa Nui

This essay will examine the historical picture of the island Rapa Nui as it is portrayed in popular science and in ecohistorical literature of the university of Gothenburg. This historical picture states that the inhabitants of the island cut down a lot of trees in the process of transporting the big and heavy statues, moai, from the quarry to the platforms along the coastline of the island. During this process all trees disappeared and resulted in soil erosion. The cultivation was destroyed and brought hunger to Rapa Nui. The following rivalry for food led to a situation of war followed by a cultural collapse.

Effektivitetsparadoxen - En eventstudie av handelsstopp på Stockholmsbörsen mellan 2003 och 2008

A trading halt is a measure conducted by a securities exchange in order to reduce information imbalances between market participants, thus enabling a higher level of market efficiency. A market is said to be efficient when new information concerning a company is instantly reflected in its stock price, implying that abnormal stock returns cannot be systematically achieved in an efficient market. The purpose of this study is to examine the occurrence of abnormal stock returns following trading halts on the Stockholm Stock Exchange. The study is based on a sample of 64 trading halts executed between January 2003 and February 2008. Historical daily prices for stocks subject to trading halts during the period have been gathered from the Datastream Advance database, while information on date and time of trading halts have been collected from the Stockholm Stock Exchange website.
