Nanoscale X-ray detectors could allow higher resolution in imaging and diffraction experiments than established systems but are difficult to design due to the long absorption length of X-rays. Here, we demonstrate X-ray detection in a single nanowire in which the nanowire axis is parallel to the optical axis. In this geometry, X-ray absorption can occur along the nanowire length, while the spatial
Neutron crystallography is a powerful method to determine the positions of H atoms in macromolecular structures. However, it is sometimes hard to judge what would constitute a chemically reasonable model, and the geometry of H atoms depends more on the surroundings (for example the formation of hydrogen bonds) than heavy atoms, so that the empirical geometry information for the H atoms used to sup
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

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
ObjectiveThe progression of joint destruction in rheumatoid arthritis (RA) is determined by genetic factors. Changes in IL4 and IL4R genes have been associated with RA severity, but this finding has not been replicated. This study was undertaken to investigate the association between IL4- and IL4R-tagging single-nucleotide polymorphisms (SNPs) and the progression rate of joint damage in RA in a mu
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
Staphylococcal enterotoxin A (SEA) is the most common enterotoxin found in outbreaks of staphylococcal food poisoning (SFP). Based on the amount of SEA produced, S. aureus strains were divided into two main groups, high- and low-SEA-producing strains. The differences in the amounts of SEA formed were found to be associated with the levels of expression of the sea gene and the bacteriophage version
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
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
