Selective pressurized liquid extraction (PLE) of polychlorinated dibenzo-p-dioxins/dibenzofurans (PCDD/Fs) and dioxin-like polychlorinated biphenyls (dl-PCBs) from various food and feed samples was performed with a selective PLE method previously developed for bulk PCBs. The method utilizes sulfuric acid impregnated silica inside the extraction cell to oxidize coextracted fat. Extractions were per
The cerebrovascular lesions of severe chronic hypertension were studied by light microscopy in perfusion-fixed, subserially sectioned brains from stroke-prone spontaneously hypertensive rats (SHRSP). The leakage and spread of plasma proteins were visualized by immunohistochemical detection of extravasated fibrinogen and by using an exogenous marker (Evans blue injected i.v.) for blood-brain barrie
The increasing emissions of carbon dioxide from fossil fuel burning are today thought to be one of the main contributors to global warming. At the same time, developing countries are striving for an increased welfare and burning more fossil fuel, which in turn is augmenting the greenhouse gas effect. In this thesis the current understanding of the connection between greenhouse gases and the climat
We analysed and compared the functioning of UV-B screening pigments in plants from marine, fresh water and terrestrial ecosystems, along the evolutionary line of cyanobacteria, unicellular algae, primitive multicellular algae, charophycean algae, lichens, mosses and higher plants, including amphibious macrophytes. Lichens were also included in the study. We were interested in the following key asp
Background. This study was performed to establish a model for quantitative measurements of a number of basic peritoneal transport parameters, particularly transperitoneal clearances (Cl) of macromolecules, during mouse peritoneal dialysis. Methods. Mice were anaesthetized using 3% isofluorane inhalation anaesthesia. The right jugular vein and the left femoral artery were cannulated for infusion a
Popular Abstract in Swedish En mängd epidemiologiska studier har visat att fuktskador i bostaden eller på arbetsplatsen ökar risken för olika typer av hälsobesvär, t.ex. astmatiska och allergiska besvär. Exakt vad som emitteras och orsakar dessa symptom i fuktskadade byggnader är inte känt, men både kemiska och mikrobiologiska agens är misstänkta. Vidare finns behov av bättre metoder för att identIt has been shown in a large number of scientific studies that living or working in a building with mould and moisture damage increases the risk for asthmatic and allergic symptoms. However, there is a need to establish more valid methods to obtain a more nuanced picture of the wide range of different types of moisture related problems. Furthermore, the causal relationships and the biological mech
Abstract Individuals within species often show a consistent differences in their risk-taking behavior. I investigated whether intra-specific variation in risk-taking behavior is adaptive, i.e. if it stems from the life history strategy differences between individuals. As a result of life history trade-offs, individuals vary in their investment into survival and reproduction, such that some indivi
Sub-Saharan Africa suffers from a severe infrastructure deficit, particularly in the power sector and this is broadly recognised as a barrier to poverty alleviation, economic growth and sustainable development in the region. At the same time, the region is rich in natural resources and the mining sector, which already makes a significant contribution to national economies is currently expanding an
Interimistiska säkerhetsåtgärder är en viktig komponent i internationella skiljeförfaranden. Emellertid är institutet förenat med en rad oklarheter. Ett sådant element är de regelverk som reglerar beviljandet av interimistiska säkerhetsåtgärder meddelade av skiljemän. Vilka förutsättningar som ska vara uppfyllda för att en skiljenämnd ska bevilja säkerhetsåtgärder är inte fastställt, och olika tilThe institute of interim measures is an integral component in international commercial arbitration. However, there are uncertainties in terms of the procedural aspects of these measures. One pertinent issue is the legal frameworks that govern the granting of arbitral interim measures. The matter of what substantive standards and requirements to apply on requests for interim measures is unresolved,
I juni förra året föreslog Kommissionen att tillämpningen av Koncentrationsförordningen skulle utvidgas till att omfatta icke-kontrollerande minoritetsförvärv. Syftet med den här uppsatsen är att bedöma huruvida den föreslagna reformen är motiverad från ett rättsligt perspektiv. Det finns belägg för att icke-kontrollerande minoritetsförvärv kan ha väsentliga negativa effekter för konkurrensen. SåIn June 2013, the Commission proposed that the scope of merger control in the EU should be extended to include non-controlling minority shareholding acquisitions. The purpose of this thesis is to assess whether the proposed legal reform is motivated from a legal perspective. There is proof that non-controlling minority shareholdings may have significant anti-competitive effects. Indeed, such acqu
Stock binds capital and this should be of highest concern for companies to minimize. Therefore it is important to design their reorder points in such way that service levels are met while keeping as low capital as possible. How well do the most common dimensioning methods perform with respect to the capital in safety stock and how the parameter is set in the best-of-breed methods to meet a given s
Ett antal flodskärningar undersöktes längs Logatafloden och dess omkringliggande områden för att ge en ökad förståelse om de senaste istiderna för denna del av världen. De påträffade sedimenten vittnade om en marin miljö efter en isframstöt och därefter en landhöjning som ledde till dagens flod- och tundralandskap. Det finns många teorier angående hur utbredd inlandsisen var över arktiska SibirieA number of sites were investigated in river sections along the Logata River on the Taymyr Peninsula, Russia, and its adjacent areas to shed more light on the glaciation history over the last glacial cycles. The sediments exposed at the investigated sites are correlated and put into a local stratigraphic scheme divided into five main units. Unit 1 is positioned lowest in the stratigraphy and con
OBJECTIVE-Previous studies have suggested that preterm birth is associated with diabetes later in life. These studies have shown inconsistent results for late preterm births and have had various limitations, including the inability to evaluate diabetic outpatients or to estimate risk across the full range of gestational ages. Our objective was to determine whether preterm birth is associated with
Background: Exposure to particulate matter (PM) is generally associated with elevated risk of cardiovascular morbidity and mortality. Elderly and obese subjects may be particularly susceptible, although short-term effects are poorly described. Methods: Sixty healthy subjects 25 males, 35 females, age 55 to 83 years, body mass index > 25 kg/m(2)) were included in a cross-over study with 5 hours of
Objective: To characterize meal patterns across ten European countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC) calibration study. Design: Cross-sectional study utilizing dietary data collected through a standardized 24 h diet recall during 1995–2000. Eleven predefined intake occasions across a 24 h period were assessed during the interview. In the p
Background: Periampullary adenocarcinomas, including pancreatic cancer, are a heterogeneous group of tumors with poor prognosis, where classification into intestinal type (I-type) or pancreatobiliary type (PB-type) is a relevant prognostic factor. The clinical significance of deficient mismatch repair (dMMR) in periampullary adenocarcinoma is comparatively unexplored. Herein, we examined the assoc
Resilience is a debated concept with numerous definitions. If focusing on describing a community under stress of a particular disruptive event, its more traditional etymological meaning of ability to spring back after deformation, or its more applied meaning of ability to cope with and recover from the event, are sufficient. However, if focusing on building and maintaining resilient communities ov
Förenligheten mellan ISDS-mekanismen i Artikel 26 i Energistadgefördraget (ECT) och EU rätt har länge varit föremål för diskussion inom EU. Denna diskussion har de senaste åren fått all mer uppmärksamhet, sedan EUdomstolen i mål C-284/16 Achmea dömde att ISDS-mekanismen i det bilaterala investeringsavtalet (BIT) mellan Nederländerna och Slovakien var oförenligt med EU rätten. Enligt kritikerna gårThe compatibility of the investor-State dispute settlement (ISDS) mechanism in Article 26 of the Energy Chart Treaty (ECT) with EU law has been a topic of intense discussion within the EU for a number of years. This discussion has gained traction in the light of the CJEU’s judgement in Case C-284/16 Achmea, where the Court declared that ISDS mechanism in the Bilateral Investment Treaty (BIT) betwe
