This study investigates the importance of implant surface topography on soft tissue response. The tissue response in the rat abdominal wall to discs of low density polyethylene with smooth to coarse surfaces was evaluated after one, six or 12 weeks. Capsule thickness and immunohistochemical quantification of monocytes-macrophages were used as measures. The macrophage specific antibody ED1 was used
Eight furanocoumarins were isolated from a methanol extract of dried roots of Angelica dahurica. One of these, phellopterin, strongly (IC50 = 0.36 microM) inhibits the binding of [3H]diazepam to central nervous system benzodiazepine receptors in vitro, while the others, despite their structural similarities with phellopterin, are considerably less active.
Knowledge about the equivalent currents distribution on a radome can be used to improve radome design, detect manufacturing errors, and to verify numerical simulations. In this paper, the transformation from near-field data to the equivalent currents distribution is analyzed. The transformation is based on a singular value decomposition of the surface integral equation that relates the equivalent
Archaeologists have often felt uneasy when encountering alternative (fringe, cult, fantastic, pseudo-) archaeologies. Some have suggested that alternative approaches and their results must be disproved, while others have been calling for better public understanding of science. My contribution takes a different point of view. I emphasize the social and cultural needs that both scientific and altern
OBJECTIVES: To analyse the neuropathological changes behind clinically defined dementia with Lewy bodies (clinDLB) compared with clinically diagnosed Alzheimer's disease (clinAD). METHODS: The prevalence of neuropathological findings in 48 clinDLB and 45 clinAD cases was compared. Sixteen clinDLB and 10 clinAD cases were reassessed with alpha-synuclein staining for Lewy bodies (LB). RESULTS: Alzhe
A unified approach is given which allows one to construct examples of all three cases resulting from a generalization of the classical Weyl limit point limit circle analysis, for differential equations as well as for difference equations.
This paper approaches the uncertainty problem from the point of view of adaptive control. The uncertainty is reduced by continuous monitoring of the response of the system to the control actions and appropriate modifications of the control law. It is shown that this approach makes it possible to deal with uncertainties that cannot be handled by high gain robust feedback control.
Invasive procedures can be performed safely in children with haemophilia due to the availability of factor VIII/IX for patients without inhibitors. Most guidelines are based on the experiences in adults, but still there is no established consensus on the optimal factor levels or duration of replacement therapy for adults undergoing surgery. Few publications have focused on surgery in children with
Solar energy conversion in photovoltaics or photocatalysis involves light harvesting, or sensitization, of a semiconductor or catalyst as a first step. Rare elements are frequently used for this purpose, but they are obviously not ideal for large-scale implementation. Great efforts have been made to replace the widely used ruthenium with more abundant analogues like iron, but without much success
In this thesis a method for doing approximate calculations of the ground state of quantum mechanical many-body systems is developed and implemented. This method uses the Hartree-Fock method as a starting point and approximates the ground state as a linear combination of non-orthogonal Slater determinants. The Slater determinants are added consecutively by minimising their associated energy while k
In the 21st century, wind power has emerged as a strong candidate in fulfilling societies goals of achieving carbon-free energy energy production. Windpower has evolved along with other technological developments, giving rise to larger turbines, but with the overall design trend remaining largely unchanged. Winfoor, a Swedish company based in Lund,aims to break that trend. With their new Triblade
In today’s rapid changing environment organisations are required to quickly adapt to the new market conditions. As a result, organisations strive to be flexible and be agile in order to cope with these conditions. Moreover, the introduction of new technologies and information systems has increased the number of middleware in IT architectures, which are considered monolithic and inflexible. SOA is
In 1996 the European Union adopted the Seveso II Directive. The Directive stated actions to be taken in the process industry in order to prevent and limit the impact of serious chemical accidents. In the Directive it is clearly stated that domino effects shall be considered, but the level of detail required is not specified. Due to that fact and the high degree of complexity linked to domino e
Kosovo, världens 193:e land, blir den sjätte staten som bildats från den serbdominerade jugoslaviska federationen sedan 1991, efter Slovenien, Makedonien, Bosnien och Montenegro som blev världens nyaste stat 2006. Kosovos status som självständig stat är dock fortfarande omstridd. Frågan om Kosovo är ett internationellt subjekt som har en rätt till externt självbestämmande och därmed är ett subjektKosovo, the world’s 193rd country, will be the sixth state carved from the former Serbian-dominated Yugoslav federation since 1991, after Slovenia, Croatia, Macedonia, Bosnia and Montenegro, which became the world’s newest state in 2006. Kosovo’s statehood is, however, still disputed. The question if Kosovo is a subject that has a right to external self-determination and therby hold international
