Popular Abstract in Swedish Avhandlingen utgångspunkt tas från den senmesolitiska boplatsen vid Motala ström, Motala stad, Östergötland, Sverige. Problematiken som diskuteras i texten utgår från frågeställningarna vad som formade de materiella uttrycken under en 500-årig tidsperiod, 5500-5000 f.Kr, dokumenterade genom arkeologiska undersökningar. Texten i avhandlingen är i analysen strukturerad i This dissertation focuses on the Strandvägen site located in the town of Motala, Östergötland, Sweden. The problem concerns what shaped the material expressions on the site during 5500?5000 B.C. For reasons of text structure the space outside the settlement site (the home) is divided into the world, the district, and the neighbourhood. These spatial concepts are finally brought together in the syn

Due to the strongly kinetic nature of the chemical events leading to the formation of mesoscopically ordered inorganic-surfactant composite materials, detailed studies on the interdependency between the degree of inorganic condensation and the co-operative self-assembly is difficult to perform. We have therefore undertaken a study where organic polyelectrolytes are used as models for the inorganic

Two photoproducts of DNA damage, i.e. cyclobutane pyrimidine dimers (CPDs) and 6-4 photoproducts (6-4PPs), induced by UV-B radiation in suspension-cultured tobacco cells were quantified by enzyme-linked immunosorbent assay (ELISA) with monoclonal antibodies. CPDs and 6-4PPs were induced in tobacco cells by UV-B radiation. Photorepair of CPDs was faster than that of 6-4PPs. UV-B radiation induces f

A fundamental assumption of theories of decision-making is that we detect mismatches between intention and outcome, adjust our behavior in the face of error, and adapt to changing circumstances. Is this always the case? We investigated the relation between intention, choice, and introspection. Participants made choices between presented face pairs on the basis of attractiveness, while we covertly

The CEDAR collaboration is developing a set of tools for tuning and validating theoretical models by comparing the predictions of event generators with data from particle physics experiments. CEDAR is also constructing resources to provide access to well defined versions of high-energy physics software and support for software developers. Here we give an overview of the CEDAR project and its statu

Background. Bioincompatible glucose degradation products (GDPs) in fluids for peritoneal dialysis (PD) develop during sterilization and storage. Their biological activity has successfully been monitored through the use of various in vitro methods but their molecular and chemical nature is less well understood. Many GDPs are highly reactive carbonyl compounds. Although some of the identified GDPs a

Although there is no biblical account of the 'Rest on the Flight into Egypt', the story is well known in the Christian world. In pseudo-Matthew the story has developed into legend form. He tells about the Christ-Child commanding the date palm Mary is resting beneath to bend down so that she can eat the fruit. It is found in literary sources from the twelfth century onwards. 'The Rest on the Flight

The adsorption and decomposition of titanium tetrachloride (TiCl4) on W(110) were studied with high-resolution core level photoelectron spectroscopy. At least two stable intermediates are formed along the pathway to TiCl4 decomposition: TiCl4(a), which is stable up to 300 K, and TiCl3(a), which is stable up to 500 K. Successive adsorption at 80 K shows that the TiCl4() species forms in the presenc

The view on reactive oxygen species (ROS) in inflammation is currently shifting from being considered damaging toward having a more complex role in regulating inflammatory reactions. We recently demonstrated a role of ROS in regulation of animal models for the autoimmune disease rheumatoid arthritis. Low levels of ROS production, due to a mutation in the Ncf1 gene coding for the Ncf1 (alias p47pho

We showed that malic enzyme and F-type ATPase isolated from glycophytes and halophytes do not differ significantly in their amino acid composition. Isolated enzymes from both types of plants showed nearly identical salt sensitivity, each, but enzyme activities in fresh homogenates from halophyte leaves apparently were more salt resistant as compared to the ones from glycophytes. These results sugg

A biphasic injectable bone substitute, suitable for filling bone defects, that sets in the body, based on calcium sulfate and hydroxyapatite (HA), is presented. For applications in bone defects the compressive strength is important to assure support of the defect site during loading when the patient is weight bearing. To control the strength, the influence of four different factors; the liquid-to-

Conditions for the introduction of terminal alkynes into the 2- and 8-positions of the Troger's base core via Sonogashira reaction of 2,8-diiodo-4,10-dimethyl-6H,12H-5,11-methanodibenzo[b,f][1,5]diazocine were established. Only the use of the bulky and electron-rich phosphine P(t-Bu)(3) as a ligand for the palladium catalyst allowed for the Sonogashira reaction to proceed effectively. In addition,
