Background: Clearance of tissue granulocytes is central to the resolution of airway inflammation. To date the focus has been on apoptotic mechanisms of cell removal and little attention has been given to alternative processes. The present study explores transepithelial migration as a mechanism of cell clearance. Method: Guinea pig tracheobronchial airways where eosinophils are constitutively pres
In this thesis, we develop and examine decision models intended for traffic engineering analysis of multiservice networks. Two important issues are addressed, namely call admission and routing control in multiservice broadband networks, and overload control in distributed-memory systems. Multiservice broadband networking generally refers to the ability to handle widely disparate traffic streams s
The fractional dispersion model for natural rivers, extended by including a first order reaction term, contains four parameters. In order to estimate these parameters a fractional Laplace transform-based method is developed in this paper. Based on 76 dye test data measured in natural streams, the new parameter estimation method shows that the fractional dispersion operator parameter F is the contr
This study deals with changes in the plant cover and its net carbon sequestration over 30 years on a subarctic Sphagnum-mire with permafrost near Abisko, northernmost Sweden, in relation to climatic variations during the same period. Aerial colour infrared images from 1970 and 2000 were compared to reveal changes in surface structure and vegetation over the whole mire, while the plant populations
We propose a rational fabrication method for nanoimprinting moulds by scanning probe lithography. By wet chemical etching, different kinds of moulds are realized on Si( 110) and Si( 100) surfaces according to the Si crystalline orientation. The structures have line widths of about 200 nm with a high aspect ratio. By reactive ion etching, moulds with patterns free from the limitation of Si crystall
Bridge splitting in chloroform of the orthometalated chloro-bridged complex [Pt(mu-Cl)(2-Me2NCH2C6H4)](2) (1), with ethene, cyclooctene, allyl alcohol and phosphine according to 1 + 2L --> 2 [PtCl(2-Me2NCH2C6H4)(L)], where L = C2H4 (3a), C8H14, (3b), CH2CHCH2OH (3c), and PPh3 (4a and 4b) gives monomeric species with L coordinated trans or cis to aryl. With olefins the thermodynamically stable isom
The Tyranny of Small Steps (TYST) behaviour has been investigated. Explained through a systemic perspective, the behaviour TYST is an unwanted change to a system through a series of small activities that may be independent from one another. These activities are small enough not to be detected by the 'surveillance' within the system, but significant enough to encroach upon the 'tolerance zone' of t
The objective of this paper is to apply the Virtual Reference Feedback Tuning (VRFT) to Multiple-Input Multiple-Output (MIMO) control strategies in wastewater treatment plants (WWTPs). Using the Benchmark Simulation Model No. 1 (BSM1) as a case study, the proposed data-driven approach provides reduced-order controllers only using a batch of input-output data points (i.e. manipulated variable-contr
Current developments in genetics and genomics entail a number of changes and challenges for society as new knowledge and technology become common in the clinical setting and in society at large. The relationship between genetics and ethics has been much discussed during the last decade, while the relationship between genetics and the political arena-with terms such as rights, distribution, experti
A data-driven reduced basis (RB) method for parametrized time-dependent problems is proposed. This method requires the offline preparation of a database comprising the time history of the full-order solutions at parameter locations. Based on the full-order data, a reduced basis is constructed by the proper orthogonal decomposition (POD), and the maps between the time/parameter values and the proje
Convergence Analysis of the Nonoverlapping Robin–Robin Method for Nonlinear Elliptic Equations CONVERGENCE ANALYSIS OF THE NONOVERLAPPING ROBIN–ROBIN METHOD FOR NONLINEAR ELLIPTIC EQUATIONS∗ EMIL ENGSTRÖM† AND ESKIL HANSEN‡ Abstract. We prove convergence for the nonoverlapping Robin–Robin method applied to non- linear elliptic equations with a p-structure, including degenerate diffusion equations

China’s approach and response to democratization in Hong Kong have since the city’s handover back in 1997 been somewhat of a rollercoaster-esque experience. The path towards democracy has for the people of Hong Kong remained an ongoing struggle for nearly 30 years, with recent developments arguably putting an end towards any hope of future realization. This study seeks to investigate and assess Be
With the ever increased focus on sustainability and not least the focus on sustainability in the tourism industry this thesis has critically investigated the suitability of the Tourism Carrying Capacity method in a Danish outdoor-tourism context. The research found that there are considerable limitations and challenges to implementing a TCC approach in Denmark, and even if implemented, legally, cu
Today, the use of business intelligence and analytics (BI&A) is an important factor to the success of organizations. There is a need to effectively analyze data in order to gain a competitive advantage and not lose its place in the market. With digitalization the amounts of data are rapidly increasing, leading to new challenges for to be able to handle it in a cost-effective way. At the same t
In 1994 Rwanda experienced a genocide that took an estimated 800.000 lives in the course of 100 days. This essay takes the form of a case study that examines Rwanda’s transitional justice process that followed and its abilities to create a gender-just peace. The study is based on a theoretical framework that links a feminist reading of transitional justice and gender-just peace together with gende
Paperboard is frequently used as a base material in packages. There is folding involved in the conversion process, where a package is formed from a paperboard sheet. However, because direct folding causes undesirable effects such as wrinkles, it must first be creased. The creasing procedure consists of intentionally damaging the material, creating an indentation on the piece, after which the mater
The General Data Protection Regulation are coming as a response to the outdated Directive from 1995. With this, a lot tougher pressures are put on organisations regarding the demand for compliance, which is mainly done through higher penalties, giving organisations an in-citement to oblige. Seen from the perspective of information systems, organisations have to implement the requirements of the re
The current thesis examines the role of intuition in the strategic decision making process of executives. Limited applied research has been conducted on the field of intuitive processes in strategic decision making of top managers, therefore this paper attempts to shed more light on this specific topic. The purpose of this study is to investigate how and to what extent intuition affects executive
Klinopyroxen har förmågan att kristallisera över ett stort intervall av temperatur, tryck och kemisk sammansättning; därför är de optimala för att studera historien för ett magmatiskt system. I den här uppsatsen analyserades fyra klinopyroxenkristaller i en ankaramit med fokus på kemi och zonering. Ankaramitprovet härstammar från Tenomassivet, Teneriffa, och bildades troligtvis i ett utbrott som sClinopyroxenes have the ability to crystallize over and respond to a large range of temperatures, pressures and chemical compositions, and thus, they are ideal for studies regarding the history of magmatic systems. In this thesis, the chemistry and zoning of four clinopyroxene crystals from an ankaramite sample from the Teno massif, Tenerife, were analysed. The ankaramites in Teno massif were, acc
The 13C mobility and cross-β-sheet structure of lipid-protein co-assemblies formed by incubating ganglioside GM3-containing model membranes with the amyloid protein α-synuclein were investigated by solid-state NMR and wide-angle X-ray scattering (WAXS) at varying lipid-to-protein ratios and membrane compositions at body temperature. The POPCGM3 model membrane was characterized by PT ssNMR and X-ra
