Popular Abstract in Swedish De möjliga energinivåerna en elektron kan befinna sig i är olika för olika atomer och joner, en atom där en eller flera elektroner kastats ut. Detta kommer att medföra att det utsända ljuset, spektret, från en atom/jon kommer att vara unik för varje atom/jon, på samma sätt som vi människor har var sitt unikt fingeravtryck.

Cytokromer har viktiga funktioner i olika typer av organismer: bakterier, växter och djur. Genom att studera vilka gener som behövs för syntesen av cytokromer i bakterien Bacillus subCytochromes are heme-containing proteins that function in electron transfer reactions, e.g. respiration and photosynthesis. There are several different types of cytochromes. C-type cytochromes differ from other types of cytochromes in that the heme group is covalently attached to the polypeptide via thioether bonds to two cysteinyl residues in a consensus motif, Cys-Xaa-Yaa-Cys-His. Cytochrome c o

Steady state and time-resolved absorption and fluorescence spectroscopy have been used to investigated the energy transfer in photosynthetic purple bacteria. Picosecond light pulses were used in measurements of Rb. sphaeroides WT and a LH1-deleted mutant, demonstrating that the energy trapping into the reaction center in both species occur on the same time-scale, and that the excitation energy is

State formation in Europe and, more precisely, the nature and development of the early modern type of state, is the focus of this book. The study of state formation has, in recent years, been heavily influenced by the works of Charles Tilly and his followers, who stress international military competition as the driving force in the development of the European states and state system, creating stro

The incidence of evaporating `black widow' pulsars (BWPs) among all millisecond pulsars is far higher in globular clusters than in the field. This implies a special formation mechanism for them in clusters. Cluster millisecond pulsars in wide binaries with white dwarf companions exchange them for turnoff-mass stars. These new companions eventually overflow their Roche lobes because of encounters a

The investigated population was all children with onset of IDDM in the participating clinics during 1988 and 1989. Of 79 diseased children, 67 participated in the study. To each child a healthy control child was chosen, 61 a

Popular Abstract in Swedish Polymerer är samlingsnamnet på långa molekylkedjor. Runt omkring oss i vårt dagliga liv är vi omgärdade av polymerer så som plaster, lim, fibrer och proteiner. Utvecklingen av många högteknologiska produkter är starkt beroende av polymera material. Grundläggande kunskaper om dem och deras egenskaper är därför viktigt. I ett batteri kan många fördelar erhållas då den koThere is a growing need for multifunctional polymeric materials for the development of several important energy conversion technologies. For example, the polymer electrolyte is a key component in lithium polymer batteries. The basic functions of this electrolyte are to efficiently conduct the lithium ions and physically separate the electrodes. Consequently, these electrolytes should ideally posse

The aim of the thesis work is the further development of practical engine simulation tools based on Stochastic Reactor Models, SRMs. Novel and efficient implementations were made of a variety of SRMs adapted to different engine types. The models in question are the HCCI-SRM, the TwoZone SI-SRM and the DI-SRM. The specific models developed were incorporated into two different interfaces: DARS-ESSA,

Abstract in UndeterminedEdge sealing is often used to assure one-dimensional moisture flow and a defined exposure area in moisture transport experiments. This paper deals with the performance of a number of edge sealing systems including wax-paraffin mix, epoxy adhesive, silicone and different tapes and films. The overall performance of the sealing systems includes vapor permeability and hygroscop

Eicosanoids are important for a wide range of physiological and pathophysiological processes.How their essential fatty acid precursors are absorbed and tissue distributed is not well charactherized. When given orally to rats, arachidonic acid (20:4) was retained in the small intestine to a larger extent than linoleic acid (18:2).More 20:4 than 18:2 was incorporated in phospholipids (PL) of the sma

Aim Spatial evolutionary and ecological vicariance analysis (SEEVA) is a simple analytical method that evaluates environmental or ecological divergence associated with evolutionary splits. It integrates evolutionary hypotheses, phylogenetic data, and spatial, temporal, environmental and geographical information to elucidate patterns. Using a phylogeny of Prepusa Mart. and Senaea Taub. (Angiosperma

Cinnamoyl-CoA reductase (CCR), an enzyme central to the lignin biosynthetic pathway, represents a promising biotechnological target to reduce lignin levels and to improve the commercial viability of lignocellulosic biomass. However, silencing of the CCR gene results in considerable flux changes of the general and monolignol-specific lignin pathways, ultimately leading to the accumulation of variou

Pollen productivity estimates (PPEs) are indispensable prerequisites for quantitative vegetation reconstructions. Estimates from different European regions show a large variability and it is uncertain whether this reflects regional differences in climate and soil or is brought about by different assessments of vegetation abundance. Forests represent a particular problem as they consist of several

Palovarotene is an oral gamma-selective retinoid agonist. In animal emphysema models, palovarotene reduced inflammation, promoted structural repair and functional improvement. REPAIR (Retinoid treatment of Emphysema in Patients on the alpha(1)-antitrypsin International Registry), was an investigator-initiated, double-blind, placebo-controlled randomised study to assess the safety and efficacy of 5

Apolipoprotein E (ApoE) is a polymorphic protein that plays a major role in lipid metabolism in the central nervous system and periphery. It has three common allelic isoforms, ApoE2, ApoE3 and ApoE4, that differ in only one or two amino acids. ApoE isoforms have been associated with the occurence and progression of several pathological conditions, such as coronary atherosclerosis and Alzheimer's d

In Laos (Southeastern Asia), Late Paleozoic sediments were identified by early French explorations across Indochina during the late 19th century (Pavie missions), but little work was undertaken to characterize the sedimentological and stratigraphical context until now. From detailed sedimentological and paleontological studies, we propose an interpretation of the depositional environment and of th

The Gram-positive bacterium Aerococcus urinae can cause infectious endocarditis (IE) in older persons. Biofilm formation and platelet aggregation is believed to contribute to bacterial virulence in IE. Five A. urinae isolates from human blood were shown to form biofilms in vitro and biofilm formation was enhanced by the presence of human plasma. Four of the A. urinae isolates caused platelet aggre

Non-melanoma skin cancers commonly contain Human Papillomavirus (HPV), but the types found have varied depending on the polymerase chain reaction (PCR) primer systems used. Whole genome amplified DNA (not amplified by any specific PCR primers) from 91 skin lesions [41 squamous cell skin carcinomas (SCCs), 8 keratoacanthomas, 22 actinic keratoses, 3 basal cell carcinomas and 17 SCCs in situ] were s

A monodispersive aerosol dynamic model, coupled to a 3D hydrodynamical grid model, has been used to study the dynamics of ultrafine particles inside a road tunnel in Stockholm, Sweden. The model results were compared to measured data of particle number concentrations, traffic intensity and tunnel ventilation rate. Coagulation and depositional losses to the tunnel walls were shown to be important p
