Genotyping of Chlamydia trachomatis is limited by the low sequence variation in the genome, and no adequate method is available for analysis of the spread of chlamydial infections in the community. We have developed a multillocus sequence typing (MLST) system based on five target regions and compared it with analysis of ompA, the single gene most extensively used for genotyping. Sequence determina
We extend the recursion formula for matrix Bessel functions, which we obtained previously, to superspace. It is sufficient to do this for the unitary orthosymplectic supergroup. By direct computations, we show that fairly explicit results can be obtained, at least up to dimension 8x8 for the supermatrices. Since we introduce a new technique, we discuss various of its aspects in some detail. (C) 20
This study addresses the problem of foreign policy change. While the 1990s has been characterized by remarkable changes in world affairs, political scientists have been slow to study the processes through which such changes take place. Drawing on the limited research that does exist in this field, the study presents an alternative explanatory model of foreign policy change, arguing that states ten
1. The cutaneous receptive fields of 225 climbing fibres projecting to the forelimb area of the C3 zone in the cerebellar anterior lobe were mapped in the pentobarbitoneanaesthetized cat. Responses in climbing fibres were recorded as complex spikes in Purkinje cells. 2. A detailed topographical organization of the nociceptive climbing fibre input to the C3 zone was found. In the medial C3 zone cli
In this letter, the authors demonstrate a vertical wrap-gated field-effect transistor based on InAs nanowires [Proc. DRC, 2005, p. 157]. The nanowires have a diameter of 80 nm and are grown using selective epitaxy; a matrix of typically 10 x 10 vertically standing wires is used as channel in the transistor. The authors measure current saturation at V-ds = 0.15 V (V-g = 0 V), and a high mobility, c
We study electron spin transport and the spin Hall effect in a quantum waveguide in the presence of Rashba spin-orbit interaction (SOI) and a homogeneous in-plane magnetic field, as well as the energy dispersion relation and spin polarization properties of the electron states in the corresponding infinite system. A general expression for the spin polarization of the outgoing flux, resulting from a
The contribution of different receptor subtypes in the contractile response during cooling in human hand vessels is of considerable interest in the understanding of cold-induced peripheral vasospasm as it appears in Raynaud's phenomenon. Subcutaneous vein segments from 50 patients undergoing hand operations not related to vascular disorders were examined in vitro. The temperature in the organ bath
Popular Abstract in Swedish Studien avser medicinsk problemlösning i sitt organisatoriska sammanhang i den svenska sjukvårdsorganisationen. Det huvudsakliga syftet är att visa hur olika typer av medicinsk problemlösning påverkas av organisationsstrukturen. För att åstadkomma detta utvecklas en typologi för medicinska problemlösningsprocesser huvudsakligen baserad på skillnader i den medicinska tekThis study is about medical problem-solving within its organisational context, the Swedish health-care organisation. The main purpose is to demonstrate how different types of medical problem-solving are affected by the structure of the health-care organisation. This involves the construction of a typology of medical problem-solving processes, and it is argued that the main characteristics of these
Sudden pipe breaks occur in water transmission pipelines and distribution mains. The consequences of these breaks can be very expensive because of the service interruption, the cost of repair, and damage to surrounding property and infrastructure. The costs associated with the pipeline breaks can be reduced by minimizing the break detection and location time. This paper presents a new continuous m
Stemflow water acidifies the soil in beech stands impacted by atmospheric deposition. To investigate whether the soil recovers from acidification, stemflow was experimentally removed. A horizon material was sampled at a distance of 10-250 cm From the stems. Before the onset of the experiment, there were stemflow-induced gradients in the saturation of exchange sites with K+, H+ and Na+ that were la
The increasing use of wireless technology utilizing unlicensed frequency bands calls for more in-depth analysis of interference and coexistence between systems. In this paper a framework is presented for detailed analysis of the performance of coexisting networks in shared frequency bands. The framework allows for multiple packet lengths to be used by the communicating devices and the analysis is
Varje år drabbas många byggnader av fuktskador. Mer än 80 procent av alla byggskador anses vara orsakade av fukt på ett eller annat sätt. Orsaken till många fuktproblem är ofta brist på kunskap om vissa grundläggande fuktmekanismer. Syftet med denna skrift är att ge läsaren de grundläggande kunskaperna och att ge förståelse och känsla för olika fenomen inom fuktmekaniken, så att man kan delta i f
PURPOSE: To report a surgical technique for transplantation of full-thickness neuroretinal sheets into the subretinal space of a large animal with a vascularized retina and to establish the light microscopic morphology of such specimens. METHODS: Twelve normal pigs underwent transplantation of a neuroretinal sheet from a neonatal donor into the subretinal space by means of a vitrectomy-based techn
Agricultural overproduction has led the European Union to encourage long-term abandonment of agricultural land. To enhance the transition of agricultural land to natural grasslands or forests different management practices in relation to vegetation can be used. The aim of this study was to understand the interactions between plant and associated soil microbial communities during the succession of
