New data on the phylogenetic relationships of various arthropod groups have spurred interesting attempts to reconstruct the evolution of arthropod nervous and visual systems. Some of the relevant new data are cell identities and developmental processes in the nervous and sensory systems, which is particularly useful for reconstructing the evolution of these systems. Here, we focus on the structure
Moraxella catarrhalis ubiquitous surface proteins A1 and A2 (UspA1/A2) interfere with the classical pathway of the complement system by binding C4b-binding protein. In this study we demonstrate that M. catarrhalis UspA1 and A2 noncovalently and in a dose-dependent manner bind both the third component of complement (C3) from EDTA-treated serum and methylamine-treated C3. In contrast, related Moraxe
Humanity has a complex relationship with the natural world. One aspect of this relationship is that of dependence on the services that the natural world provides. Commonly referred to as ecosystem services, these are services such as the provisioning of freshwater, timber, and medicines, the regulation of climate, and the maintenance of air quality. This relationship is especially important in the
The aim of this study is to investigate whether a virtual environment can be used as a complement to conventional experiments regarding human behaviour in fires and evacuations. Initially, a study of previous research in the field of human behaviour in fires and Virtual Reality was performed. To be able to do a validation of the use of Virtual Reality in relation to conventional experiments, a pre
The lack of housing in Stockholm is a fact. People ask for centrally located housing and the demand is contributing to increased prices. There are clear political message of creating more housing in the city, while construction of new buildings, and conversion of older buildings, are limited by rules and laws. City Planning establishes follows and modifies overviews and detailed plans of the city.
In this thesis, the value of the two composed financial products (structured products), sprinters and auto-calls, are studied and compared to the European call option. The study is preformed using both analytical and numerical solutions, where the underlying is either said to follow a GBM-process (Geometric Brownian Motion) or a GARCH-process (Generalized Autoregressive Conditional Heteroskedastic
Syftet med denna studie är att utforska huruvida före detta patienter upplever att DBT-behandling inom barn- och ungdomspsykiatrin har bidragit i skapandet av ett liv värt att leva. Semistrukturerade intervjuer genomfördes med åtta kvinnor i åldern 17-22 år som genomgått DBT-behandling för mellan ett till tre och ett halvt år sedan. Intervjumaterialet analyserades med hjälp av Interpretative PhenoThe study aims to investigate whether former patients experience that DBT-treatment in a child and adolescent psychiatric clinic has helped them in building a life worth living. Semi-structured interviews were conducted with eight women aged 17-22 years who had undergone DBT treatment one to three and a half years ago. The data were analyzed using Interpretative Phenomenological Analysis (IPA), wh
The motivation for the project is to investigate what happens if I add a second Earth in the Solar System and project it forward in time. I add an Earth mass planet (called Earth two) in the same orbit as the Earth on the other side of the Sun (i.e. six months ahead of the original Earth). I then investigate how the perturbation of the second Earth effects the Solar System in the short and the lon
Amid the many food safety scandals and rapid urbanization, China’s peri-urban areas have recently witnessed the emergence of alternative food systems (AFSs). Situated in a context different from that of the West, their impact has remained poorly understood and under researched. This paper explores how Community Supported Agriculture (CSA) can enhance food security in China’s cities. Based on Polan
