Using kilometric arrays of air Cherenkov telescopes at short wavelengths, intensity interferometry may increase the spatial resolution achieved in optical astronomy by an order of magnitude, enabling images of rapidly rotating hot stars with structures in their circumstellar disks and winds, or mapping out patterns of nonradial pulsations across stellar surfaces. Intensity interferometry (once pio
Enhanced biological phosphorus removal (EBPR) was studied in laboratory scale experiments as well as in a full scale EBPR process. The studies were focused on carbon source transformations, the use of nitrate as an electron acceptor and characterisation of the microflora. A continuous anaerobic/aerobic laboratory system was operated on synthetic wastewater with acetate as sole carbon source. An ef
Popular Abstract in Swedish Alla levande organismer består av celler som tillsammans med molekyler generellt kallade extracellulär matrix bildar en vävnad. Celler innehåller fyra huvudgrupper av byggstenar: socker, fettsyror, aminosyror och nukleotider, vilka i tur och ordning bildar kolhydrater, fetter, proteiner och nukleinsyror. I vävnaderna pågår en ständig omsättning av byggstenarna och molekThis thesis describes structural and functional studies of alpha-1-microglobulin (a1m), a 26 kDa plasma and tissue protein that is evolutionarily well-conserved and belongs to the lipocalin superfamily. The lipocalins are polypeptides of 160-190-amino acids that are folded into an 8-stranded beta-barrel forming a pocket with a hydrophobic interior. a1m carries heterogeneous yellow-brown chromophor
Identification and isolation of cardiomyocytes from the heart, embryonic stem cells, or induced pluripotent stem cells is a challenging task and will require specific isolation techniques. Less than 30% of the cells within the murine heart are cardiomyocytes and, what is more, there are multiple sub-populations of cardiomyocytes like atrial, ventricular and conduction system cardiomyocytes. In Pap
Organic farming may contribute substantially to future agricultural production worldwide by improving soil quality and pest control, thereby reducing environmental impacts of conventional farming. We investigated in a comprehensive way soil chemical, as well as below and aboveground biological parameters of two organic and two conventional wheat farming systems that primarily differed in fertiliza
STUDY OBJECTIVE--The aim of the study was to investigate the receptor events that mediate the vascular effects of 5-hydroxytryptamine (5-HT) on human coronary arteries, since 5-HT has long been thought to play a role in coronary artery vasospasm. DESIGN--Recently available selective receptor agonists and antagonists were used to examine the 5-HT receptor subtypes present in human epicardial corona
Popular Abstract in Swedish Det norra barrskogsbältet, även kallat de boreala skogarna, sträcker sig runt hela norra halvklotet. Det utgör en tredjedel av den globala skogsytan, och innehåller hälften av den totala mängden kol finns lagrat i samtliga skogsekosystem. Trots de låga temperaturerna, den korta vegetationssäsongen och en liten mängd inkommande solenergi under året, är dessa ekosystem viIn boreal forests, the main factors limiting biomass production are the harsh climate, which combines a short growing season and low annual levels of incoming solar energy, and the limited availability of nitrogen. These limitations will be directly affected by climate change, and may in turn substantially affect the carbon budget of the boreal forests, the production of wood and biofuel, biodiver
Sulfur-containing compounds are used as rescue agents to protect normal tissue from the toxic side effects of cis-[PtCl2(NH3)(2)] (cisplatin) without affecting its anti-tumour activity. Reactions of the model complexes [Pt(dien)Cl](+) (1) and [Pt(dien)(GSMe)](2+) (2) (GSMe = S-methylglutathione) with the rescue agents glutathione (GSH), thiourea, thiosulfate, and diethyldithiocarbamate (DDTC) have
The principal fate during litter decomposition and mineralization is rather well established only for a limited number of elements, mainly essential plant nutrients and a few potentially very toxic metals. Elements which occupy the majority of the positions in the periodical system seems almost unknown in this context. The objectives were, therefore to assess differences in the behavior of 58 mine
BACKGROUND: Dietary fibre food intake is related to a reduced risk of developing diabetes mellitus. However, the mechanism of this effect is still not clear. The aim of this study was to evaluate the effect of commercial fibre cereals on the rate of gastric emptying, postprandial glucose response and satiety in healthy subjects. METHODS: Gastric emptying rate (GER) was measured by standardized rea
Synopsis In methanol solutions of Zeise's salt, the parent complex [PtCl3(C2H4)]- as well as its solvolysis product, trans-[PtCl2(C2H4)(MeOH)], exchange rapidly with free ethene. The olefin exchange process, which is largely entropy controlled, involves the substitution labile site trans to the coordinated ethene. Abstract Complex equilibria in methanol/chloroform/dichloromethane solutions contain
In pristine Sphagnum-dominated peatlands, (di)nitrogen (N2) fixing (diazotrophic) microbial communities associated with Sphagnum mosses contribute substantially to the total nitrogen input, increasing carbon sequestration. The rates of symbiotic nitrogen fixation reported for Sphagnum peatlands, are, however, highly variable, and experimental work on regulating factors that can mechanistically exp
Background-Diabetes mellitus (DM) and cardiovascular disease are associated with dyslipidemia, but the detailed lipid molecular pattern in both diseases remains unknown. Methods and Results-We used shotgun mass spectrometry to determine serum levels of 255 molecular lipids in 316 controls, 171 DM, and 99 myocardial infarction (MI) events from a cohort derived from the Malmö Diet and Cancer study.
Background: Ovarian tumours are usually surgically removed because of the presumed risk of complications. Few large prospective studies on long-term follow-up of adnexal masses exist. We aimed to estimate the cumulative incidence of cyst complications and malignancy during the first 2 years of follow-up after adnexal masses have been classified as benign by use of ultrasonography. Methods: In the
Research suggests that polyphenols, such as anthocyanins, that are found in considerable amounts in many types of berries, contributes with a positive effect on human cognition. However, clinical trials are warranted to support these findings. Preparation for such a trial includes developing a berry-rich study product and a corresponding reference beverage. Phenolic compounds are highly unstable a
Heterogena katalysatorer för användning i bränslecellssystem har undersökts baserat på aktiv fas och tillverkningsmetoder för granulat- och monolitkatalysatorer. Katalysatorerna tillverkades genom att använda θ – aluminiumoxid som bärare, dopad med lantan och cerium, där den aktiva fasen bestod av ädelmetall X och nickel i varierande halter. Analys gjordes genom att låta en blandning av vattenångaHeterogeneous catalysts to be used in a pre-reformer for fuel cell systems have been investigated based on active phase composition and catalyst preparation methods for granulate and monolithic catalysts. The catalysts were manufactured using θ – aluminum oxide as carrier, promoted with lanthanum and cerium, with active phases consisting of noble metal X and nickel in various concentrations. Analy
Do sick birds migrate at different times than healthy ones? The word migration comes from the Latin migratus that means “to change”, referring to how birds change their geographic locations seasonally. Birds migrate to escape from decreased food availability or harsh weather on their breeding grounds. They migrate to areas of high or increasing resources where they stay during the winter period b
