Modern societies' functionality is strongly dependent on the electricity. Efficient, environment friendly, and economical power production has been in focus for a long time. The introduction of computers and thereby computer-aided tools for pre-design studies, optimization and choice of the best operational strategies, has changed the conditions for power production tremendously. The most noticeab

The basic helix–loop–helix proteins form a special group of transcription factors unique for the eukaryotic organisms. They are crucial for the embryonic development of many fundamental organ systems such as muscle, heart, central nervous system, hematopoiteic system, and many others. They are very flexible in terms of regulating transcription in that they can either promote or repress transcripti

Introduction: Intervention thresholds (ITs), the 10-year hip fracture risk at which treatment can be considered to be cost-effective, have previously been estimated for Sweden and the UK. Objective: The aim of this study was to provide a Markov cohort model platform for a multinational estimation of thresholds at which intervention becomes cost-effective and to investigate and determine the main f

On the basis of evidence from Icelandic I argue that PRO can be both governed and case-marked, but crucially not properly governed. Lexical arguments must be both case-marked and properly head governed, and proper head government is a strictly local relation whereas case-marking is not. As the subiect position of PRO clauses is not properly head governed, it must not be lexicalized, irrespective o

Campylobacteriosis is a zoonotic disease in which birds have been suggested to play an important role as a reservoir. We investigated the prevalence of Campylobacter jejuni subsp. jejuni in black-headed gulls (Larus ridibundus) in southern Sweden with the aim of examining the nature of C. jejuni infection in this bird species. Birds were sampled in four sampling series each year during 1999 (n = 4

In order to characterise fires in chemical warehouses, 38 medium scale experiments have been conducted. The experiments were performed in a 0.66m3 combustion chamber. On-line measurements were made of combustion gases (CO2, CO, HC and NOx), mass loss, smoke, temperatures, external radiation and phi-values. Intermittently gas and soot samples were collected and analysed for content of organic compo

The effect of allergen challenge on the number of leucocytes and the concentration of endothelin 1-like immunoreactivity (ET-LI) in bronchoalveolar lavage fluid (BALF) was investigated in guinea-pigs sensitized to Ascaris suum. The animals were twice exposed to allergen aerosol. All animals responded to the second challenge with bronchoconstriction. Twelve hours later, a significant increase in th

Popular Abstract in Swedish Varför ser staden ut som den gör? Vilka krafter ligger bakom bebyggelsens och transportsystemets utformning? Vad eller vilka aktörer har inflytande över hur staden utformas? Hur kan internationella olikheter i städers utformning förklaras? De krafter som formar staden är många och komplexa. Stadens struktur har under historiens gång påverkats av bland annat nya teknologWhy do cities appear the way they do? What are the underlying forces that contribute to its built environment and transport system? What/whom are the factors/actors that influence the ways in which the city is shaped? How can the international differences in the shape of cities be explained? The driving forces that shape the city are numerous and complex. City structure, has through the ages, been

The neutron beam at the Studsvik facility for boron neutron capture therapy (BNCT) and the validation of the related computational model developed for the MCNP-4B Monte Carlo code are presented. Several measurements performed at the epithermal neutron port used for clinical trials have been made in order to validate the Monte Carlo computational model. The good general agreement between the MCNP c

Effects of hydrogen bonding and the axial ligand interaction on the B800 band in two LH2 complexes Rhodopseudomonas (Rps.) acidophila and Rhodospirillum (Rs.) molischianum have been theo retically investigated by using density functional theory. The local electrostatic environment of the B800 bacteriochlorophyll is simulated as an atomic charge field consisting of the pigments in the protomer unit

The present European Standard for footwear testing (EN 344) classifies footwear thermally by a temperature drop inside the footwear during 30 minutes at defined conditions. Today, other methods for footwear thermal testing are also available. The aim of this study was to compare EN 344 with thermal foot method. Six boots were tested according to both methods. Additional tests with modified standar
