Modelling Change in Ground Vegetation Response to Acid and Nitrogen Pollution, Climate Change and Forest Management in Sweden 1500--2100 a.d.

The ForSAFE model, designed for modelling biogeochemical cycles (water, acidity, base cation, nitrogen and carbon) in terrestrial ecosystems, was modified with a vegetation response module (VEG), incorporating the effects of: nitrogen pollution, acidification, soil moisture, temperature, wind chill exposure, light and shading by trees, grazing by animals, competition between plants, above ground f

Public and Non-Profit Interaction : U.S. Assistance to Eastern European Media 1989-1995

This study explores the relationships among U.S. public and non-profit organizations against the backdrop of the assistance they rendered to news media in Eastern European countries between 1989 and 1995. Ideological and administrative goals and strategies used by organizations such as the Department of State, the USAID, and the USIA, the International Media Fund, the Soros Foundations, the Freedo

High-temperature and high-concentration SCR of NO with NH3: Application in a CCS process for removal of carbon dioxide

This study investigates several commercial selective catalytic reduction (SCR) catalysts (A–E) for application in a high-temperature (approximately 525 °C) and high-concentration (5000 ppm NO) system in combination with CO2 capture. The suggested process for removing high concentrations of NOx seems plausible and autothermal operation is possible for very high NO concentrations. A key property of

Multi-agent source seeking via discrete-time extremum seeking control

Recent developments in extremum seeking theory have established a general framework for the methodology, although the specific implementations, particularly in the context of multi-agent systems, have not been demonstrated. In this work, a group of sensor-enabled vehicles is used in the context of the extremum seeking problem using both local and global optimisation algorithms to locate the extrem

Early exposure to secondhand tobacco smoke and the development of allergic diseases in 4 year old children in Malmo, Sweden

Background: Earlier studies have shown an association between secondhand tobacco smoke and allergy development in children. Furthermore, there is an increased risk of developing an allergy if the parents have an allergy. However, there are only few studies investigating the potential synergistic effect of secondhand tobacco smoke and allergic heredity on the development of an allergy. Methods: The

{1-[1-(3-Carboxypropanamido)ethyl]-1',2-bis(diphenylphosphino)ferrocene-kappa2P,P'}dichloridoplatinum(II) dichloromethane 1.25-solvate

The dinuclear title compound, [FePtCl2(C17H14P)(C23H23NO3P)]x1.25CH2Cl2, has a slightly distorted cis-PtCl2P2 square-planar geometry around the Pt atom, and the ferrocenylphosphine ligands are staggered at an angle of 29.4 (2) deg. about Pt. In the crystal structure, the complex forms centrosymmetric dimers via two strong intermolecular O—H-O bonds resulting in R22(8) rings. A weak intramolecular

A Comparison Between Unitary and Non-Unitary Precoder Design for MIMO Channels with MMSE Detection and Limited Feedback

This work studies the design of linear precoder codebooks for N-r x N-t MIMO channels with MMSE detection at the receiver. A natural split of precoder-design is unitary precoding and non-unitary precoding. Unitary precoding is only performing rotation of the data in a way beneficial for the channel. Non-unitary precoding additionally also uses power-loading to further improve the performance. Some

Understanding the migration ecology of European red admirals Vanessa atalanta using stable hydrogen isotopes

Tracking migratory movement of small animals with variable migration patterns is difficult with standard mark-recapture methods or genetic analysis. We used stable hydrogen isotope (delta D) measurements of wings from European red admirals Vanessa atalanta to study several aspects of this species' migration. In the central part of southern Europe we found large differences in delta D values betwee

Assessment of quality of life in lymphedema patients: validity and reliability of the Swedish version of the Lymphedema Quality of Life Inventory (LQOLI)

The Lymphedema Quality of Life Inventory (LQOLI) is an instrument developed for patients with different types of lymphedema. It contains physical, emotional, social, and practical dimensions and consists of 58 items, each with three sub items concerning life quality, daily life changes, and difficulties of changing and two items concerning life quality in general and in relation to lymphedema. The

Time lags in biodiversity response to farming practice

Agri-environmental schemes have been applied with the goal to mitigate negative effects of agriculture on biodiversity and ecosystem functioning. However, on evaluating the schemes the results have been variable and shown both positive and neutral effects. These variable effects can be attributed to not taking into account important factors affecting the variables at test, such as biodiversity. Th

Birth after Caesarean Section

Popular Abstract in Swedish Förlossning efter kejsarsnitt Kejsarsnitt utgör för närvarande cirka 17% av alla förlossningar i Sverige. En konsekvens av detta är att allt fler kvinnor kommer till specialistmödravården för rådgivning om vilket förlossningssätt som är säkrast vid förlossningen efter ett kejsarsnitt. Två möjligheter finns: planerad vaginal förlossning eller planerat kejsarsnitt. När maBirth after caesarean section (CS) is an issue of growing importance. As a consequence of increasing CS rates, more women having experienced a prior CS will need counselling about preferred second delivery mode. There are two choices: elective repeat caesarean section (ERCS) or trial of labour (TOL). It is well known, that a TOL ending in an emergency CS carries the largest risks for mother and ch

Approximate solution of boundary integral equations for biharmonic problems in non-smooth domains

This paper deals with approximate solutions to integral equations arising in boundary value problems for the biharmonic equation in simply connected piecewise smooth domains. The approximation method considered demonstrates excellent convergence even in the case of boundary conditions discontinuous at corner points. In an application we obtain very accurate approximations for some characteristics

Strong molecular field effects in Auger decay of the potassium 2p core-hole state in molecular KCl, KBr and KI

The K 2p photoionization and subsequent LMM Auger decay have been studied for molecular gas-phase KCl, KBr and KI. The detected manifold spectral structure of the Auger electron spectrum of KCl has been interpreted to originate from strong molecular field effects. This indicates that Auger decay on potassium side of originally very ionic molecules creates inner-shell hole states with a strong mole

On Stern-Gerlach coincidence measurements and their application to Bell's theorem

We analyze a coincidence Stem-Gerlach measurement often discussed in connection with the derivation and illustration of Bell's theorem. The treatment is based on our recent analysis of the original Stern-Gerlach experiment [H. Wennerstrom and P.-O. Westlund, Phys. Chem. Chem. Phys. 14, 1677 (2012)1, where it is concluded that it is necessary to include a spin relaxation process to account for the

Kommunikation, medborgarskap och deltagardemokrati

Popular Abstract in Swedish Det görs en rad försök till demokratisk förnyelse ute i kommunerna. I denna avhandling är det min ambition att analysera ett sådant försök; medborgarutskotten i Helsingborg. De frågeställningar avhandlingen behandlar är 1) vad ligger bakom samtalets betoning i medborgarutskottens deltagardemokratiska aktiviteter? 2) Hur positioneras kommuninvånare som medborgare då medThis is a study of civic communication in a municipal setting. In the south Swedish municipality of Helsingborg operated Civic Committees between 2003 and 2006. The Civic Committees organized different kinds of activities together with the citizens out in the different neighbourhoods of the municipality, such as open meetings, neighbourhood walks, workshops for the future and meetings with specifi

Overcoming the Nyquist Limit in Blood Flow Velocity Estimation

Spectral Doppler ultrasound imaging typically consists of a spectrogram, showing the velocity distribution of the blood, and a brightness (B-) mode image allowing the operator to navigate. It is desirable to have both high spectral and velocity resolution, so that details in the blood flow can be traced, as well as a high B-mode frame rate to allow for tracking of movements and to adjust the posit

Ability of risk scores to predict a low complication risk in patients admitted for suspected acute coronary syndrome.

Background When acute coronary syndrome (ACS) cannot be ruled out, emergency department (ED) patients with chest pain are admitted for in-hospital observation because of the risk of complications such as arrhythmia and acute heart failure. A study was undertaken to compare the ability of three risk prediction models to identify patients at a very low risk of complications. Methods 559 consecutive
