Positron annihilation lifetime spectroscopy (PALS) was performed on a series of polydimethylsiloxane (PDMS)/fumed silicon dioxide (SiO2) composites at temperatures between -185 and 100degreesC to study the effect of filler content and filler particle size on the free volume properties and the positron annihilation characteristics. The glass transition behavior of the PDMS/SiO2 composites was deter

Preservatives are widely used to prevent microbial growth both for skin care products and in the industry. Many of them have allergic potential. Allergic contact dermatitis caused by preservatives can often be chronic, probably because it is difficult to suspect contact allergy to these chemicals based on the patient's history only. Formaldehyde is a common cause of contact allergy and has been in

The translocation t(1;19)(q23;p13)/der(19)t(1;19) is a risk stratifying aberration in childhood B-cell precursor acute lymphoblastic leukaemia (BCP ALL) in the Nordic countries. We have identified 47 children/adolescents with t(1;19)/der(19)t(1;19)-positive BCP ALL treated on two successive Nordic Society of Paediatric Haematology and Oncology (NOPHO) protocols between 1992 and 2007 and have revie

The deposition of polystyrene latex particles (0.23 mum in radius) onto a glass surface, covered with indium-tin oxide, has been studied using a wall-jet cell. The particle deposition could be followed in a single experiment at several positions, exposed to a wide range of wall shear rates. A deposition model including a shielding function was applied in order to describe the process. Three shield

BACKGROUND: Anisakis simplex (A.s.) allergy is an emerging disease. The third-stage larvae of this nematode are a source of hidden allergens in fish. There are no clear guidelines concerning dietary restrictions for patients with serum-specific IgE to this parasite. OBJECTIVE: To follow up the clinical data and immunological parameters of patients sensitized to A.s. during 6 to 23 months. METHODS:

AIMS: The majority of all breast cancers are hormone responsive, traditionally defined by the expression of oestrogen receptor (ER) alpha and/or progesterone receptors. In contrast to ERalpha, the clinical significance of the relatively recently identified ERbeta is still unclear. This study aimed to define the relationship between ERbeta and clinicopathological parameters in a mixed cohort of bre

The aim of this paper is to analyze, with a broadly postcolonial sensibility, the discourses on culture found in some of the international management books that: 1) especially claim to emphasize the cultural factor, and 2) claim to be ‘international’, supposedly appropriate for reading in all parts of the globe. We intend to show that very similar discursive patterns characterize the conceptualiza

Popular Abstract in English Among the forms of life found in extreme environments (e.g. high temperatures ‘thermo’ and oxygen deficient ‘anaerobe’), the thermoanaerobic bacteria emerge as a highly evolved and interesting subject of study. Bacteria living as microbial mats in decaying plant material possess a great potential not only to degrade complex biomass but also to produce special chemicals.A novel ethanol-producing thermoanaerobe Caloramator boliviensis 45BT (=DSM 22065T, =CCUG 57396T) was isolated from a hot spring of the Bolivian highlands. C. boliviensis possesses the ability to utilize a wide range of substrates and can efficiently convert hexoses and pentoses into ethanol with concomitant production of acetate, carbon dioxide and hydrogen as by-products of fermentation. However

Standard ODE methods such as linear multistep methods encounter difficulties when applied to differential-algebraic equations (DAEs) of index greater than 1. In particular, previous results for index 2 DAEs have practically ruled out the use of all explicit methods and of implicit multistep methods other than backward difference formulas (BDFs) because of stability considerations. In this paper we

SynopsisReactivity trends of thioethers toward square-planar complexes can be generally interpreted by use of an equation of the form: log k = γ + α∑σ* + βθ, where k denotes second-order rate constants, ∑σ* the sum of Taft constants for the thioether substituents, and θ the thioether cone angles. γ represents an intrinsic parameter for each substrate complex, while α is an electronic and β a steriSynopsisReactivity trends of thioethers toward square-planar complexes can be generally interpreted by use of an equation of the form: log k = γ + α∑σ* + βθ, where k denotes second-order rate constants, ∑σ* the sum of Taft constants for the thioether substituents, and θ the thioether cone angles. γ represents an intrinsic parameter for each substrate complex, while α is an electronic and β a steri

In this chapter, I discuss combined quantum mechanics (QM) and molecular mechanics (MM; QM/MM) calculations for proteins. In QM/MM, a small but interesting part of the protein is treated by accurate QM methods, whereas the remainder is treated by faster MM methods. The prime problems with QM/MM calculations are bonds between the QM and MM systems, the selection of the QM system, and the local-mini

Popular science summary Comparison of ectoparasite load on barnacle geese (Branta leucopsis) in arctic and temperate regions Some birds winter in warm regions, but breed in the arctic. This long migration takes up a lot of energy, which leaves scientists wonder why birds undertake this journey. One of the many hypotheses to explain it, is that there are fewer parasites in the arctic. Therefore,

Det blir allt vanligare att människor flyttar mellan länder för att bo, studera, arbeta eller leva som pensionär. Till en persons hemvist knyts allt fler rättigheter och skyldigheter i samhället vilket skapar ett ökat behov för individen och staten att kunna fastställa var en person har sin hemvist. Idag finns ingen enhetlig tolkning av hemvistbegreppet. En persons hemvist kan därför variera mellaToday it is common for people to move across borders to live, study, work or retire. A person’s residence is linked to an increasing number of rights and obligations in society, which creates an increased need for both the individual and the state to determine where a person has its residence in different situations. Today there is no uniform interpretation of the concept. Where a person is consid

Denna uppsats behandlar self-cleaning vid uteslutning av leverantörer till följd av brott som innefattar bestickning eller korruption. Närmare bestämt utreder uppsatsen vilka bedömningsgrunder en upphandlande myndighet börha vid bedömningen av en leverantörs self-cleaning härom. Som en konsekvens av att ha begått brott som innefattar bestickning eller korruption kan en leverantör uteslutas från aThis essay concerns self-cleaning in connection with exclusion of public contract suppliers due to bribery or corruption. More specifically, the essay examines on what grounds contracting authorities should assess a self-cleaning. As a consequence of being found guilty of bribery or corruption, suppliers can be excluded from the procurement procedure. However, the newly introduced Swedish Public

Located in Båstad, at the Bjäre peninsula, is the camping business Båstad Camping. With many guests from all over of Sweden, the owners of the business want to convey information about tourist attractions, sporting activites, events and restaurants at the Bjäre peninsula in a modern way. The purpose of the thesis is to develop a visitors mobile application with information about the Bjäre peninsul

I detta examensarbete åtar jag mig uppgiften att analysera bevisteori gällande svensk straffprocessrätt utifrån ett kunskaps- och vetenskapsteoretiskt perspektiv. Härvid försöker jag först besvara frågan om vilka idéer eller föreställningar om kunskap som kommer till uttryck i bevisteorin. Jag gör dock inte anspråk på någon uttömmande uppräkning av dessa, utan vill snarare ge en översikt över ett In this graduate thesis I set out to analyze Swedish evidence theory (as it pertains to procedural law in criminal cases) using epistemology and philosophy of science. In doing so, I have attempted to answer question of which ideas or concepts, borrowed from these two disciplines, can be found in Swedish evidence theory, whether explicit or implicit. On this account, it has not been my aim to give

Since the year of 2015 to current date we have witnessed border controls being established within the European free movement region - the Schengen area. An intensified threat of terrorism and uncontrolled movement of people in the Schengen area has created skepticism towards the agreement itself. The objective of this case study is to examine the Schengen agreement's impact on the area's s

Kolhydrater kan användas som en energikälla i kroppen, men de kan även användas för mycket mer än så. I alla organismer finns celler vars ytor är täckta av olika sockermolekyler vilka är avgörande för cellernas överlevnad samt kommunikation med andra celler. Ett exempel på ett sådant socker är sialinsyra; en syrlig kolhydrat med en nio kol lång kolkedja. Patogener, exempelvis en del bakterier, kanSialic acids are a large family of acidic sugars. One of the most abundant is N-acetylneuraminic acid. Sialic acids are found at the terminal position of glycan chains of all cell types. Their wide distribution makes them have a broad set of biological functions, for example cell to cell interaction and communication. Bacteria can utilize sialic acid for two purposes; 1) as a source of carbon, nit

The following paper examines discussions of feminism online and how participants orientate themselves in these. The specific case consists of a swedish separatist Facebook group for women and non-binary people. The group has over 100000 members and has a constant flow of activity where members interact with each other in different ways. Among this activity there is discussions of feminism, often l
