Studies of intermediate energy heavy ion reactions have revealed the existence of a number of reducibility and thermal scaling properties in nuclear multifragmentation. In particular, the probability of emitting n-fragments is reducible to the probability of emitting a single fragment through the binomial distribution. The resulting one-fragment probability shows a dependence on the thermal energy
Popular Abstract in Swedish Avhandlingens syfte är att undersöka energianvändningen och miljöpåverkan från bostäder. Sju autentiska byggnader byggda under 1990-talet i Sverige har studerats. De är analyserade med avseende på energianvändningen och miljöpåverkan under deras livscykel: tillverkning av byggnadsmaterial, transport av byggnadsmaterial och -komponenter till byggarbetsplats, uppförande, The objective of this thesis is to investigate the energy use and environmental impact of residential buildings. Seven authentic buildings built in the 1990s in Sweden are investigated. They are analysed according to energy use and environmental impact during their life cycle: manufacture of building materials, transport of building materials and components to the building site, erection to a buil
In 1993-1998 the lichen flora of Stora Karlso and Lilla Karlso was surveyed. These two nearby islands are situated outside the west coast of Gotland, Sweden, in the Baltic Sea. In all, 355 species were found, including three lichenicolous fungi. Two species are new to Sweden, viz. Lepraria flavescens and Placynthium lismorense. Both were found on limestone. The number of species according to habit
DNA chemical and physical networks have been investigated with respect to their stability and swelling, and rheological properties. Chemical networks were prepared by cross-linking DNA with ethylene glycol diglycidyl ether (EGDE), and physical networks by association with cationic polymers. Both types of gels display strong elastic properties and have a shear thinning behaviour. Addition of cation
Absorption, reflection and emission polarization spectra of CdWO4 crystals have been studied in the region 3.5-30 eV in order to distinguish the excitonic and electron-hole processes in the vicinity of the band gap. The following parameters have been defined from the Urbach tail study at 6-300 K: E-0 = 5 eV, sigma(0) = 0.31, homega = 70 meV (565 cm(-1)). Excitonic processes have been shown to domi
Ferrochelatase, the enzyme catalyzing metallation of protoporphyrin IX at the terminal step of heme biosynthesis, was co-crystallized with an isomer mixture of the potent inhibitor N-methylmesoporphyrin (N-MeMP). The X-ray structure revealed the active site of the enzyme, to which only one of the isomers was bound, and for the first time allowed characterization of the mode of porphyrin macrocycle
The three dimensional structures of human prostate specific antigen (PSA) and glandular kallikrein (hGK) were modeled based on porcine pancreatic kallikrein A. High sequence similarity and conserved framework of serine proteases enabled accurate modeling. The catalytic site region consisting of catalytic triad, residues forming oxyanion hole and main-chain substrate binding residues were conserved
Recent work indicates that cartilage oligomeric matrix protein (COMP) plays an important role in extracellular matrix assembly and matrix-matrix protein interactions. In order to identify the proteins in extracellular matrix that interact with COMP, we used an ELISA-based solid-phase binding assay, which revealed a specific, high-affinity interaction between COMP and fibronectin. This interaction
This chapter focuses on the use of different methods for isolation of alkylresorcinols. Alkylresorcinols are members of a lipid group called non-isoprenoid phenolic lipids. Different aspects of the extraction by classical methods and supercritical CO2 are discussed. Supercritical CO2 extraction of alkylresorcinols from rye bran is discussed for the first time. As compared to the classical extracti
Reflux of equimolecular amounts 2-aminobenzylamine and isatins in acetic acid produced indolo[3,2-c]quinolin-6-ones in good yields. A proposed mechanism involving initial formation of a spiro compound is given. This isolable intermediate subsequently rearranges via a sequential isocyanate ring opening and a cyclisation process to a urea derivative which finally cyclized to the indolo[3,2-c]quinoli
OBJECTIVE: The purpose of this study was to assess the effectiveness of electronic fetal monitoring (EFM) alone and with additional ST analysis (EFM + ST) in laboring women with a singleton term pregnancy that is in cephalic presentation in the prevention of metabolic acidosis by the application of individual patient data metaanalysis. STUDY DESIGN: We conducted an individual patient data metaanal
Streptococcus pneumoniae infections remain a major cause of morbidity and mortality worldwide. Therefore a detailed understanding and characterization of the mechanism of host cell colonization and dissemination is critical in order to gain control over this versatile pathogen. Here we identified a novel 72 kDa pneumococcal protein endopeptidase O (PepO), as a plasminogen and fibronectin binding p
Learning is widespread in nature, occurring in most animal taxa and in several different ecological contexts and, thus, might play a key role in evolutionary processes. Here, we review the accumulating empirical evidence for the involvement of learning in mate choice and the consequences for sexual selection and reproductive isolation. We distinguish two broad categories: learned mate preferences
Human aquaporin 2 (AQP2) is a water channel found in the kidney collecting duct, where it plays a key role in concentrating urine. Water reabsorption is regulated by AQP2 trafficking between intracellular storage vesicles and the apical membrane. This process is tightly controlled by the pituitary hormone arginine vasopressin and defective trafficking results in nephrogenic diabetes insipidus (NDI
Molecular spiders are synthetic molecular motors featuring multiple legs that each can interact with a substrate through binding and cleavage. Experimental studies suggest the motion of the spider in a matrix is biased toward uncleaved substrates and that spider properties such as processivity can be altered by changing the binding strength of the legs to substrate [R. Pei, S. K. Taylor, D. Stefan
A supercritical fluid extraction (SFE) method has been developed for the extraction of lipids in bilberry. Experimental design was used to optimize pressure, temperature and extraction time using CO2 as solvent. Best SFE condition for total lipids was 450 bar, 60 °C and 45 min. The SFE method was compared to conventional Bligh & Dyer (B&D) extraction. The amount of fatty acid methyl esters
ANCA-associated vasculitis is commonly found in elderly patients, but there are few data concerning outcome and treatment in the highest age groups.
Purpose – The purpose of this paper is to look more closely at the residents’ attitude to individual heat metering and charging systems (IMC) of multi-family dwellings in residential properties, and to evaluate the tenant’s perception of IMC and how it may affect the continued expansion of such systems. Design/methodology/approach – The research in this paper is based on a questionnaire and interv
For triangles with linear vertex motion, common practice is to backface cull a triangle if it is backfacing at both the start and end of the motion. However, this is not conservative. We derive conservative tests that guarantee that a moving triangle is backfacing over an entire time interval and over the area of a lens. In addition, we present tests for the special cases of only motion blur and o
