Popular Abstract in Swedish Arbetet som presenteras i denna avhandling handlar om att utveckla nya processer för att producera gasformiga biobränslen som är mer energieffektiva än de som används idag. Genom att göra processerna mer energieffektiva kan kostnaden för att producera biobränslen minskas. En lägre produktionskostnad för biobränslet gör det lättare att ersätta fossila bränslen med förnyeReplacing fossil fuels with biofuels is one way of reducing the emission of greenhouse gases into the atmosphere, thus decreasing our impact on the global climate. For this to be a viable option, several production routes are needed, as no single option can fully replace fossil fuels. One way of making biofuels more competitive with fossil fuels is by reducing the production cost. As most of the p

In this paper we estimate the computational cutoff rate for sequential decoding when used together with short interleaving to communicate over the Gilbert-Elliot channel.

Pickering emulsions are emulsions that are stabilized by fine particles. They have been the focus of considerable research in the past decade due to their properties such as high stability with respect to coalescence and Ostwald ripening, as well as due to advances in nanotechnology that allows us to create and characterize nano-scale structures in new ways. This work reviews some of the recent wo

We give a simpler proof of the formula, due to J.-L. Lions, for the reproducing kernel of the space of harmonic functions on a domain Omegasubset ofR(n) whose boundary values belong to the Sobolev space H-s(partial derivativeOmega), and also obtain generalizations of this formula when instead of harmonic functions one considers functions annihilated by a given elliptic partial differential operato

The aim of this study was to estimate costs of treating venous leg ulcers in Sweden and the United Kingdom during 1 year and to quantify costs in different health states, The costs of treating four different types of venous leg ulcers were estimated for 52 weeks by a stochastic health economic model, which simulated resource use data obtained from prospectively collected patient data, expert panel

Based on an extensive cohort study over 25 years, the present study supports the assumption that major osteoporotic fractures can be reasonably predicted from hip fracture rates. The construct for FRAX models depends on algorithms to adjust for double counting of fracture outcomes in some models and in others, to estimate the incidence of a major fracture from hip fracture rates. The aim of the pr

The dynamics and consequences of host-parasite coevolution depend on the nature of host genotype-by-parasite genotype interactions (G × G) for host and parasite fitness. G × G with crossing reaction norms can yield cyclic dynamics of allele frequencies ("Red Queen" dynamics) while G × G where the variance among host genotypes differs between parasite genotypes results in selective sweeps ("arms ra

The New Zealand emissions trading scheme (ETS) wasintroduced by legislation in 2008. The legislated objectives asstated in section 3 of the Climate Change Response Act 2002are to ‘support and encourage global efforts to reduce theemission of greenhouse gases by (i) assisting New Zealandto meet its international obligations under the [UNFCCC].

A new class of chiral non-racemic gamma- and delta-amino alcohols based on bicyclo[2.2.1]heptane and bicyclo[2.2.2]octane have been synthesized and used as catalysts in the asymmetric diethylzinc addition to benzaldehyde. (C) 2008 Elsevier Ltd. All rights reserved.

ObjectiveTo investigate if caesarean section (CS) increases the risk for childhood asthma and gastroenteritis with reference made to children born with vaginal delivery (VD). MethodsRetrospective study of data from linked Swedish medical service registers - Medical Birth Registry (MBR) and Hospital Discharge Registry (HDR). Data were obtained from women without any background/perinatal morbidity

Objective: To validate self-reported information on weight and height in an adult population and to find a useful algorithm to assess the prevalence of obesity based on self-reported information. Research Methods and Procedures: This was a crosssectional survey consisting of 1703 participants (860 men and 843 women, 30 to 75 years old) conducted in the community of Vara, Sweden, from 2001 to 2003.

The latest Cyrtograptus lundgreni graptolite Chron (Late Wenlock, middle Silurian) is characterized globally by the Mulde Event faunal extinctions and glacio-eustatic sea-level change. Only in the last decade has it been recognized as one of the most severe extinction events of the Silurian Period. A section spanning the Slite Group-Halla Formation boundary on the islet Ytterholmen off main Gotlan

The Oskarshamn and Forsmark areas in the Fennoscandian Shield, SE Sweden, have been chosen as potential sites for hosting highly radioactive nuclear waste. To evaluate their respective suitability, the geological history of the bedrock in these two areas has been investigated. This study has focused on the thermal evolution, from c. 500 °C to c. 50 °C. 40Ar-39Ar geochronology on hornblende, muscov

Background Rheumatoid arthritis (RA) and osteoarthritis (OA) are important musculoskeletal diseases that the EUMUSC.NET project developed Standards of Care (SOC) for. Objective The purpose was to explore factors to enable successful implementation of the SOC for RA and OA. Methods A combined set of methods was used; a literature search, a European survey among patients, clinicians and policymakers

While the world's transport energy matrix is still strongly linked to limited and heavily polluting fossil fuels, new markets are appearing for the production and use of alternative transport fuels, such as liquid biofuels. Due to an interconnected global economy, such markets today are developing oil a global scale with actors looking to meet local as well as potential international demand. The a
