Large-scale patterns of genetic variation in chloroplast (cp) and nuclear DNA in the widespread European herb species Silene latifolia and S. dioica were investigated using cpPCR-RFLPs, non-coding cpDNA sequences, AFLPs and sequences of the internal transcribed spacers (ITS) of nuclear ribosomal DNA (rDNA). The results of the analyses of cpDNA variation using PCR-RFLPs and non-coding sequence data
Two typical configurations of solid oxide fuel cells (SOFCs) are planar cross-flow and tubular counter-flow. Even though their performance is based on the same physical principles, their operation characteristics and parameters vary considerably due to different geometries. The goals of this paper are to detect the particularities of the cell geometries at transient operation and to identify their
When it goes into operation in 2016, the MAX IV 3 GeV storage ring will be the first ultralow-emittance storage ring based on a multibend achromat lattice. Such ultralow-emittance rings make use of a large number of weak bending magnets which leads to low radiation losses in the dipoles compared to power radiated from insertion devices. Therefore, the emittance in such rings depends strongly on th
Accessibility in public outdoor environments is an important issue for persons with reduced functional capacity, for example older persons, and is also crucial for older pedestrians’ safety. The aim of the paper is to evaluate the importance and satisfaction of accessibility issues in public outdoor environments the year around as perceived by older persons (65 years old and above). Within two bef
Popular Abstract in Swedish Bakgrunnen for den foreliggende avhandling er et ønske om å utnytte moderne tredimensjonell bildeanalyse for å forbedre undersøkelse og tolkning av synsnervehodets (papillens) form og størrelse (topografi). Synsnervehodet representerer den delen av synsnerven som trer inn i bakre del av øyet gjennom senehinnen (sklera). Den normale synsnerve har ca 1.2 millioner nervetrEvaluation of the optic nerve head topography is one of the most important methods to diagnose and monitor patients with glaucoma. Until recently, optic nerve head topography has most often been judged by either ophthalmoscopy or from optic disc photographs. These methods are subjective and examiners do not have access to absolute measurements of the optic disc size and cup depth. The result of su
In the turning operation the relative dynamic motion between cutting tool and workpiece, or vibration, is a frequent problem, which affects the result of the machining, and in particular, the surface finish. Tool life is also influenced by vibration. Noise in the working environment frequently occurs as a result of dynamic motion between the cutting tool and the workpiece. The research study inclu
The paper addresses the challenges of supply chain management in the electronics sector influenced by the trends of globalisation, production outsourcing and emerging product-related environmental policies. The trends have forced the original equipment manufacturers (OEMs) to take eco-design and supply chain management (SCM) initiatives, which pose challenging demands on the suppliers in developin
The new European Commission took office on 1 November 2014, with a number of structural changes including the creation of a First Vice-President, a responsibility given to the former Dutch Foreign Minister Frans Timmermans. The First Vice-President will ensure that every Commission proposal respects the principles of subsidiarity and proportionality. If the Commission pays more attention to the pr
Popular Abstract in Swedish Strålbehandling av cancerpatienter sker idag med avancerad teknik och utrustning. Förberedelserna inför behandlingen är omfattande och kräver medverkan av flera olika personalkategorier och övervakning via datoriserade verifikationssystem. I varje led i förberedelsekedjan finns en potentiell risk för avvikelser, vilka kan vara både systematiska eller tillfälliga i sin nThe aim of this work was to develop, implement and evaluate an independent system with which to calculate the absorbed dose, delivered by high-energy X-ray beams, to the prescription point and the depth of dose maximum. The introduction of such a system in the clinical routine may help ensure high-quality treatment and avoidance of errors which may jeopardise the clinical outcome of the treatment
In trying to understand any aspect surrounding the success and failure of information systems practice, concepts of organisational analysis become increasingly important. Many issues arise and must be dealt with when an information system is to be developed and implemented. In order to avoid information system failures information system analysts should adopt an approach, which exploits the intrin
We report on the interfacial behaviour of a series of nonionic diblock copolymers at solid hydrophobic and hydrophilic surfaces/water and silicone oil/water interfaces, studied by ellipsometry. The polymers consist of a hydrophobic C-18 chain linked to a hydrophilic poly(ethylene oxide) (PEO), block varying from 50 to 250 U. The adsorption of these copolymers at low bulk concentrations was found t
Laser annealing experiments are performed on cold rolled IF steel whereby highly localized microstructure and property modification are achieved. The microstructure is seen to develop by strongly heterogeneous recrystallization to provide steep gradients, across the submillimeter scale, of grain size and crystallographic texture. Hardness mapping by microindentation is used to reveal the correspon
Familial dilated cardiomyopathy is a rare cause of dilated cardiomyopathy (DCM), especially in childhood. Our aim was to describe the clinical course and the genetic variants in a family where the proband was a four-month-old infant presenting with respiratory problems due to DCM. In the family, there was a strong family history of DCM and sudden cardiac death in four generations. DNA was analyzed
Sweden is generally regarded as a country with little corruption, equal rights for men and women and a strong emphasis on democratic values. Still, the appointment of political representatives to the boards of municipal corporations occurs without consideration of these values. One step towards increasing our knowledge about the governance of municipal corporations in Sweden is to look at how curr
