The relationship between airway responsiveness to bronchoconstrictor- and cough-inducing stimuli has been examined in Ascaris suum-sensitized conscious guinea-pigs. Guinea-pigs were sensitized to Ascaris suum [4000 PNU and 100 mg Al(OH)3 i.p. on days 1 and 7] and then challenged with aerosolized antigen on days 21, 28 and 35. At day 35, antigen-exposure produced an early bronchoconstrictor respons

A number of filamentous fungi are known to produce high levels of saline-soluble and low-molecular-mass lectins. The function of these proteins are not clear but it has been proposed that they are involved in storage of nutrients, development, recognition of other organisms, and defense reactions. A gene encoding such a lectin (AOL) was deleted in the nematode-trapping fungus Arthrobotrys oligospo

This work discusses methods to obtain reference following on unstable systems. The task is critical; introduction of refernce signal might cause instability in some cases. It is thus interesting to develop strategies that offer acceptable reference following, but also guarantees stability. In practice similiar problems arises in flight control systems for unstable fighter aircrafts. Experimental v

The European food service market was estimated, in 1999, to be worth US$293 billion with high profit margins and a growth rate of 2.75%. Future demand for value-added products and high levels of customization will stress the issue of keeping profit margins in the food service industry. Packaging is a critical issue, because it adheres to the product throughout the entire food service supply chain.

Analysis of atrial rhythm is important in the treatment and management of patients with atrial fibrillation. Several algorithms exist for extracting the atrial signal from the electrocardiogram (ECG) in atrial fibrillation, but there are few reports on how well these techniques are able to recover the atrial signal. We assessed and compared three algorithms for extracting the atria] signal from th

We consider the problem of covering arbitrary polygons with rectangles. The rectangles must lie entirely within the polygon. (This requires that the interior angles of the polygon are all greater than or equal to 90 degrees.) We want to cover the polygon with as few rectangles as possible. This problem has an application in fabricating masks for integrated circuits. In this paper we will describe

Numerical modeling of combustion in flames and gas flows and gas flows generated by fires in compartments has been carried out. The laminar flamelet model has been used to model combustion in different degrees of vitiation in order to model fire gas recirculation which occurs in compartment fires. CFD modeling (computational fluid dynamics) has been used in the calculation of the flow field. The f

The focus of this thesis is on the use of wave splitting in electromagnetic direct and inverse scattering problems. Wave splitting offers a decomposition of wave fields into appropriate input and output wave constituents. Several different wave splittings are studied including one-dimensional, multi-dimensional energy-flux, and multi-dimensional locally exact wave splittings. The Bremmer series is

The problems following the translation of “queer theory” and of the term ”queer” into a non-American context still have an impact on the debates in the field of queer studies. Through a presentation of the discussions held at the PhD-course What’s up in Queer Theory? Recent Developments in Queer Studies organized in May 2007, the article investigates some of the implications following the translat

Free radicals have been suggested to play a role in the development of diabetic retinopathy. The aim of the present study was to examine whether the metabolic perturbations caused by high-fat feeding of two strains of mice, the C57BL6/J mice and the NMRI mice, interfere with one of the free radical enzyme defense systems in the retina, i. e., glutathione (GSH), and whether morphological changes oc

Lenodus variabilis occurs in an interval in the lower to middle Kundan Stage which includes the Arenig-Llanvirn boundary. The lower part of its range constitutes the L. variabilis Zone, the upper part, where it co-occurs with Yangtze-placognathus crassus, making up the Y. crassus Zone. The conodont faunas of these two consecutive conodont biozones have been investigated in 14 sections from south,
