Papillomaviruses (PV) are a remarkably heterogeneous family of small DNA viruses that infect a wide variety of vertebrate species and are etiologically linked with the development of various neoplastic changes of the skin and mucosal epithelia. Based on nucleotide similarity, PVs are hierarchically classified into genera, species and types. Novel human PV (HPV) types are given a unique number only
The relatively new combustion concept known as partially premixed combustion (PPC) has high efficiency and low emissions. However, there are still challenges when it comes to fully understanding and implementing PPC. Thus a predictive combustion tool was used to gain further insight into the combustion process in late cycle mixing. The modeling tool is a stochastic reactor model (SRM) based on pro
The identification of a subterranean metallic ore from scattering experiments, conducted on the surface of the ground or in a bore hole, is a classic geophysical problem. In general this problem is not well-posed. However, a priori information about the shape of the target provides enough regularization to make the problem numerically stable. The problem is solved by minimizing the mean-square err
In this study we describe combustion simulations of a single sector and a fully annular generic multi-burner aero-engine combustor. The objectives are to facilitate the understanding of the flow, mixing and combustion processes to help improve the combustor design and the design process, as well as to show that it is now feasible to perform high-fidelity reacting flow simulations of full annular g
Idag behandlas många former av cancer med joniserande strålning från linjäracceleratorer. Målet med behandlingen är att sterilisera cancercellerna med så liten påverkan som möjligt på den friska vävnaden. För att uppnå detta är det viktigt att ha en så bra bestämning som möjligt av den absorberade dosen till tumör- och normalvävnad. För detta ändamål används idag tredimensionella dosplaneringssystA Monte Carlo generated linear accelerator is implemented into a pencil beam based treatment planning system (TPS) to study the possibility to verify the TPS with a Monte Carlo method. The implemented accelerator is then used to study two inhomogeneous lung geometries; lungslab and mediastinium. Advantages of a Monte Carlo method over conventional measurements are that accelerator output variation
Aim: To explore the long-term learning process in movement awareness development supported by a video-based learning model. Participants: Eleven undergraduate nursing students. Method: The students participated in learning sessions comprising video modelling, video feedback and reflective enquiry with a focus on inter-personal interaction. Each student participated in three individual video sessio
Child malnutrition is one of the major health problems in many developing countries and involves many sectors such as health, agriculture and research. Malnutrition in infants usually develops during the introduction of complementary foods, due to a deficit of nutrients, low energy density and the poor bioavailability of vitamins and minerals leading, in turn, to an increase in the risk of disease
Phlorotannins are bioactive polyphenols in brown macroalgae that make these algae interesting as healthy food. Specific phlorotannins are, however, seldom identified, and extracts from different species are often only analysed for total phenolic content (TPC). In this study, our focus was to identify phlorotannin molecules from Saccharina latissima and Ascophyllum nodosum (a species rich in these

This thesis studies the role of interaction between charged particles for transport and optical properties in nanostructures. Simulations are provided for a quantitative description of the system dynamics probed by either current spectroscopy or light absorption. In the first part of the thesis (Part I) the basic theories are described and in the second part of the thesis (Part II) the papers lis

The exploitation of migrant workers is widespread in the Nordic countries in labour intensive sectors. This article investigates whether there is any criminal law protection in practice for exploited migrant workers in Sweden. On the basis of descriptive statistics regarding the outcomes of criminal investigations on human trafficking for forced labour and on human exploitation for forced labour a
Plastic production and disposal have excessively contributed to climate change and other environmental problems. Therefore, the green route for the production of recyclable polymers, which is industrially and economically practical, is indispensable. 2,5-furan dicarboxylic acid (FDCA) synthesised from 5-Hydroxymethylfurfural (HMF) is a new alternative biobased resource for polymers. FDCA has been
The body shows impressive control capabilities in terms of the speed and the precision with which movements can be carried out under a wide variety of circumstances. The cerebellum and brainstem nuclei, including the cuneate nucleus, are believed to play a crucial role in this control. If these control mechanisms can be unveiled, this could yield important insights in not only medicine and neuroph
