Functionalities of clay-polymer nanocomposites (CPN) are related to the degree of clay particle exfoliation and orientation within the polymer matrix. Exploration of new physical methods for such CPN processing is currently an active field of research. In the present work, organoclay polypropylene nanocomposites were prepared by melt intercalation and subsequently exposed to an electric field (E)
The identification of the regions where vector-borne diseases are transmitted is essential to study transmission patterns and to recognize future changes in environmental conditions that may potentially influence the transmission areas. SGS1, one of the lineages of Plasmodium relictum, is known to have active transmission in tropical Africa and temperate regions of Europe. Nuclear sequence data fr
OBJECTIVE: To determine the degree of plasma volume expansion by 0.9% NaCl in relation to the infused volume, in sepsis/SIRS (systemic inflammatory response syndrome), after a standardized hemorrhage, and in a normal condition. DESIGN: Prospective, randomized animal study. SETTING: University hospital laboratory. SUBJECTS: Thirty anesthetized adult male rats. INTERVENTIONS: The study was performed
Interactions between iron (Fe) and arsenic (As) play a vital role in aquatic and terrestrial ecosystems influencing the reactivity and transport of arsenic. A key aspect is the effect of natural organic matter (NOM) on these interactions, and previous investigations have reported the existence of ternary As-Fe-NOM species. In this study, the reactivity of Fe, from a boreal stream water, towards As
Assessment of compliance with dietary interventions is necessary to understand the observed magnitude of the health effects of the diet per se. To avoid reporting bias, different dietary biomarkers (DBs) could be used instead of self-reported data. However, few studies investigated a combination of DBs to assess compliance and its influence on cardiometabolic risk factors. The objectives of this s
Attempts have been made to make traditional local foods a part of the tourists' experiences, but few have caught great interest among the tourist and leisure consumers. An exception is the Norwegian traditional Sheep's-head meal. This article focuses on driving factors behind this success. Sheep's heads have been continuously available and used at private meals, albeit the status of the meals has
The blackcap (Sylvia atricapilla) is a common Palearctic migratory warbler, and haemosporidian parasites are common in this species. However, genetic and phenotypic diversity of haemosporidians in warblers has been insufficiently investigated and poorly linked. We addressed this issue by combining molecular and microscopy data for detection of pigment-forming haemosporidians of the genera Haemopro
Background/Objectives:The degree of misclassification of obesity and undernutrition among elders owing to inaccurate height measurements is investigated using height predicted by knee height (KH) and demispan equations.Subjects/Methods:Cross-sectional investigation was done among a random heterogeneous sample from five municipalities in Southern Sweden from a general population study 'Good Aging i
To better understand how silkmoth cocoons maintain the correct internal moisture levels for successful pupation, we examined cocoons from the long-domesticated mulberry silkmoth Bombyx mori as well as from two wild silkmoth species, Antheraea pernyi and Philosamia cynthia ricini. We determined fluid-independent values for the porosity, tortuosity and permeability of the inner and outer surfaces of
In this paper we study the interaction between starch which has been hydrophobically modified, with octenyl succinic anhydride (OSA), and alpha-beta-livetin, which is the water soluble fraction of egg yolk. The modification of the starch renders it surface active and also incorporates a carboxyl group to the starch, which can be negatively charged. The interaction was studied both in solution and
Popular Abstract in Swedish Oberoende av om det är i ett samhälle, datornätverk eller organen i en mänsklig kropp, så är behovet av kommunikation stort i en komplex miljö. Eftersom den komplicerade människokroppen är beroende av kommunikation för att reglera funktioner, skickas otaliga mängder signaler oavbrutet. För att signalerna skall vara meningsfulla så måste de kunna tas emot och behandlas. Intercellular communication is of crucial importance in regulating physiology and G-protein coupled receptors (GPCRs) have evolved as an important mechanism in this process. Of the approximately 800 human GPCRs, about 160 are still considered to be “orphan” receptors for which an endogenous ligand remains to be identified. Since an estimated 50% of all clinical drugs act on 30 known GPCRs, the rem
The Cognitive Interview (CI) is a well-researched interview method and the research results show that CI, compared with more conventional interview styles, enhances witnesses’ memory. However, not much research has been done on the question of how CI affects the realism of eyewitnesses’ judgments of confidence in the veracity of their interview statements. In a previous study (Granhag, Jonsson &am
Reaction of the tricobalt carbyne cluster [Co-3(mu(3)-CH)(CO)(9)] with chiral diphosphines of the Josiphos and Walphos families affords the new clusters [Co-3(mu(3)-CH)(CO)(7)(P-P*)] in good yield (P-P* = J004 (1), J005 (2), J007 (3), W001 (4), W003 (5)). The new alkylidyne tricobalt clusters, and the previously known [Co-3(mu(3)-CH)(CO)(7)(mu-J003)], have been tested as catalysts/catalyst precurs
Objective. The aim of the study was to determine the effect of -ketoglutarate on the blood lipid profile using a rat animal model with experimentally induced hypercholesterolaemia. Material and methods. The female and male (30/30) Wistar rats had ad libitum access to a diet containing cholesterol (1 %) and lard (10 %) throughout the entire experimental period (120 days). On day 60 of the study, bo
Complementary measures for the assessment of patient thermoregulatory state, such as subjective judgement scales, might be of considerable importance in field rescue scenarios where objective measures such as body core temperature, skin temperature, and oxygen consumption are difficult to obtain. The objective of this study was to evaluate, in healthy subjects, the reliability of the Cold Discomfo
Narkosläkemedlet racemiskt ketamin är en blandning av lika delar S(+)- och R(–)-ketamin,två spegelvända läkemedelsmolekyler (sk enantiomerer) med något olika effekter.Ketamin började användas på patienter i mitten av 1960-talet och har sedan dess fascineratbåde läkare, forskare och patienter pga sina smärtstillande och sömngivande, menäven hallucinatoriska, effekter. Redan efter några års användniRacemic ketamine, introduced in the mid-sixties, contains equal proportions of the enantiomersS(+)- and R(–)-ketamine. Early clinical reports indicated unfavourable effectson intracranial pressure (ICP) and on the cerebral circulation. Current literature on thistopic is however sparse, and available reports are divergent. The aim of this doctoraldissertation project was to study cerebral and syste
The direct response and the short-term recolonisation of soil by fungi and bacteria were studied after heat treatments of a humus soil with high carbon content and low pH. and a calcareous soil with lower carbon content and high pH. Heating was administered using a muffle furnace or an autoclave, with different temperatures and times of heat exposure, after which fresh soil (1%) was added as inocu
During the latest early Campanian, a diverse vertebrate assemblage inhabited the shallow coastal waters of the Kristianstad Basin, southernmost Sweden. The taxon-rich fauna includes numerous species of sharks, rays, chimaeroids, bony fish, mosasaurs, plesiosaurs, aquatic birds, crocodiles, and turtles. Vertebrate fossils have been found at several localities within the basin, representing at least
A methodology for estimation of the unknown physical parameters in a detailed model for chromatographic processes is proposed. The model describes the concentration of the solute in the mobile phase and considers external/internal mass transfer resistance. The external volume and its mixing effect are also considered. The unknown model parameters estimated are the bed void, the axial dispersion co
