The response of tundra plants to enhanced UV-B radiation simulating 15 and 30% ozone depletion was studied at two high arctic sites (Isdammen and Adventdalen, 78 degrees N, Svalbard).The set-up of the UV-B supplementation systems is described, consisting of large and small UV lamp arrays, installed in 1996 and 2002. After 7 years of exposure to enhanced UV-B radiation, plant cover, density, morpho
An adsorbent was developed from mature leaves and stem bark of the Neem (Azadirachta indica) tree for removing zinc from water. Adsorption was carried out in a batch process with several different concentrations of zinc by varying pH. The uptake of metal was very fast initially, but gradually slowed down indicating penetration into the interior of the adsorbent particles. The data showed that opti
Immunohistochemical expression of CD40 is seen in 60-70% of diffuse large B-cell lymphoma (DLBCL) and is associated with a superior prognosis. By using gene expression profiling we aimed to further explore the underlying mechanisms for this effect. Ninety-eight immunohistochemically defined CD40 positive or negative DLBCL tumors, 63 and 35 respectively, were examined using spotted 55K oligonucleot
Few studies have explored the possible plasma cholesterol lowering effects of rye consumption. The aim of this secondary analysis in the SYSDIET study was to investigate the association between plasma alkylresorcinols (AR), a biomarker for whole grain wheat and rye intake, and blood lipid concentrations in a population with metabolic syndrome. Furthermore, we analyzed the associations between the
In this paper, the transversal diffusion coefficient D of CO2 dissolved molecules through the wall of a hydrated cellulose fiber was approached, from the liquid bulk diffusion coefficient of CO2 dissolved molecules modified by an obstruction factor. The porous network between the cellulose microfibrils of the fiber wall was assumed being saturated with liquid. We retrieved information from previou
OBJECTIVES: We examined approaches to reduce sodium content of food served in settings operated or funded by the government of the County of Los Angeles, California.METHODS: We adapted health impact assessment methods to mathematically simulate various levels of reduction in the sodium content of food served by the County of Los Angeles and to estimate the reductions' potential impacts on mean sys
The atmospheric organic aerosol is a tremendously complex system in terms of chemical content. Models generally treat the mixtures as ideal, something which has been questioned owing to model-measurement discrepancies. We used an oxidation flow reactor to produce secondary organic aerosol (SOA) mixtures containing oxidation products of biogenic (α-pinene, myrcene and isoprene) and anthropogenic (m
Air-starved combustion of biomass and fossil fuels releases aerosols, including airborne carbonaceous particles, causing negative climatic and health effects. Radiocarbon analysis of the elemental carbon (EC) fraction can help apportion sources of its emission, which is greatly constrained by the challenges in isolation of EC from organic compounds in atmospheric aerosols. The isolation of EC usin
Introduction: Airway obstruction and possible concomitant pulmonary diseases in COPD cannot be identified conventionally with any single diagnostic tool. We aimed to diagnose and grade COPD severity and identify pulmonary comorbidities associated with COPD with ventilation/perfusion single-photon emission computed tomography (V/P SPECT) using Technegas as the functional ventilation imaging agent.
Popular Abstract in Swedish Den fysiska planeringen innebär interaktion mellan aktörer inom skilda samhällssfärer där parter med skilda sociala positioner, resurser, perspektiv och värderingar möts. Aktörernas bilder av vilka effekter ett givet planförslag medför och vilka effekter som ska betraktas som de mest centrala varierar regelmässigt. Mellan de berörda parterna är det därför inte ovanligt Since planning in connection with new building projects frequently generates controversy, it can be seen as a typical form of contentious politics. The aim of this dissertation is to analyze siting controversies, their origin, development and termination, in efforts to explore the problem of legitimacy in planning processes of this sort. The research approach employed is that of a multiple case s
Background: The International Study Group for Pancreatic Surgery provides globally accepted definitions for reporting of complications after pancreatic surgery. This International Study Group for Pancreatic Surgery project aims to provide a standardized framework for reporting of the results of operative treatment for chronic pancreatitis. Methods: An International Study Group for Pancreatic Surge
Objective. To analyze the fine specificity of IgG autoantibodies in sera from rheumatoid arthritis (RA) patients for type II collagen (CII) epitopes that are arthritogenic in collagen-induced arthritis (CIA), a relevant murine model of RA. Methods. For enzyme-linked immunosorbent assay (ELISA) analysis of conformation-dependent autoantibody binding, recombinant chimeric collagens that harbor the r
Integrity of cartilage fails in joint disease. The current work aimed to identify candidate active proteinases in joint diseases using an in vitro model for cartilage degradation induced by interleukin-1. A critical event in the process of cartilage destruction in joint disease is the failure of the collagen fiber network to maintain integrity. Proteins binding to the surface of the fibers are lik
The aim of this thesis is to develop statistical models to reconstruct past land cover composition and human land use based on fossil pollen records over Europe for different time periods over the past 6000 years. Accurate maps of past land cover and human land use are needed when studying the interaction between climate and land surface, and the effects of human land use on past climate. Existing
Platinum(II) complexes of the type [Pt(thioether)2Cl]+(thioether = dimethyl sulfide, thioxane) are capable of abstracting a phenyl group from the BPh4 counterion with formation of trans[Pt(thioether)2ClPh] compounds. Thermal reactions proceed both in the solid phase and in nitromethane solution at elevated temperature and have preparative importance. Phenylation of the Pt(II) centre also occurs in
This article picks up on a term (‘cross-fertilisation’) often exploited in debates on the interaction of international laws and legal practices, especially in the context of international criminal law. Two questions are addressed: (1) What is the meaning of ‘cross-fertilisation’? (2) What are its conditions? As the article argues, ‘cross-fertilisation’ pertains to the understanding of legal uttera
Fake canonizations are prevalent in the former communist countries wherein arts and culture in general may still function as propaganda weaponry at the hands of the sponsoring state. The public is almost eliminated from the process of canonization, as the publishing houses, art galleries, and cultural industries seldom survive and flourish from sales to a real public. As a rule, their rarefied pub
Urgent structural change is required in higher education to allow collaboration both within and acrossuniversities so that achieving a rapid sustainability transition can become the overarching and mainpurpose of education, research and work in society. A review of the literature reveals that fragmentation,caused by traditional hierarchical faculty and disciplinary organisation, is a major obstacl
The system of welcoming newly arrived students in Sweden has experienced numerous modifications since its inception. Additionally, because the interpretation of education laws us left to the municipalities and head teachers, the various policies have resulted in a multitude of local practices. Over the years, a very wide range of models for organising newcomer reception have therefore been tried o
Farmers as volunteers in research could potentially provide a rich resource for exploring sustainable agricultural research questions. To discern emerging patterns in citizen science-based studies on topics with relevance for sustainable agriculture, and reveal salient challenges and opportunities for conducting such studies, we conducted a systematic literature review of 27 peer-reviewed articles
