A method using optimal control results as input to operator assist systems, automatic functions and autonomous construction machine control is presented. This method complements the vast research within autonomy to achieve the most fuel efficient solution from results that are already available from concept evaluation and system optimization in early development. The optimal control results are va

Extremely metal-poor (EMP) stars are an integral piece in the puzzle that is the early universe, and although anomolous subclasses of EMP stars such as carbon-enhanced metal-poor (CEMP) stars are well studied, they make up less than half of all EMP stars with [Fe/H] ∼ -3.0. The amount of carbon depletion occurring on the red giant branch (carbon offset) is used to determine the evolutionary status

Abstract. Objectives. To ascertain whether a relationship exists between the PiZ alpha1‐antitrypsin (α1AT) variant and antineutrophil cytoplasm antibodies (ANCA)‐positive vasculitis in a large group of Swedish patients, and whether analysis for the presence of the PiZ variant might be useful for diagnostic or prognostic purposes. Design. Retrospective cross‐sectional study. Setting. The Department

The study investigated the effects of forest residue extraction on tree growth and base cations concentrations in soil waterunder different climatic conditions in Sweden. For this purpose, the dynamic model ForSAFE was used to compare theeffects of whole-tree harvesting and stem harvesting on tree biomass and the soil solution over time at 6 different forestsites. The study confirmed the results f

In this thesis degradation of chlorinated solvents, e.g., tetrachloroethene (perchloroethylene [PCE]), has been examined, both natural occurring degradation and in situ remediation strategies. The projects included have focused on two field sites of former dry-cleaning facilities, which are contaminated with PCE in both the groundwater and the sediments. One site had only been exposed to natural d

Atmospheric inversions are used to derive constraints on the net sources and sinks of CO2 and other stable atmospheric tracers from their observed concentrations. The resolution and accuracy that the fluxes can be estimated with depends, among other factors, on the quality and density of the observational coverage, on the precision and accuracy of the transport model used by the inversion to relat

Gasoline Partially Premixed Combustion (PPC) is a promising alternative combustion concept that can offer both high indicated efficiency and low exhaust emissions in terms of NOx and soot, compared to conventional diesel combustion (CDC). Previous research has shown that PPC can operate with gasoline-like fuels of varying RON numbers. Some of the most promising results come with the use of gasolin

A comparison was made between two plant peroxidases, cationic horseradish peroxidase (HRP) and anionic tobacco peroxidase (TOP), combined with a highly cationic osmium polymer [Os(4,4'-dimethyl-2,2'-bipyridine)2poly(N-vinylimidazole)10Cl]+2/+ ([Os(dmp)PVI]+/2+) to develop highly sensitive, stable and selective hydrogen peroxide biosensors. The two different plant peroxidases were individually immo

Background: The food addiction (FA) model is receiving increasing interest from the scientific community. Available empirical evidence suggests that this condition may play an important role in the development and course of physical and mental health conditions such as obesity, eating disorders, and other addictive behaviors. However, no epidemiological data exist on the comorbidity of FA and gamb

PURPOSE:: To describe riboflavin and ultraviolet light (UV) collagen crosslinking as an effective treatment for infectious keratitis. METHODS:: A 25-year-old previously healthy female contact lens user was diagnosed with unilateral severe keratitis with unclear pathogenesis, although the clinical presentation suggested acanthamoeba as the infectious agent. A 4-mm diameter, annular, semi-opaque inf

Objective. To analyze the experience of a single centre using stent-grafts for treatment of complicated acute aortic type B-dissections (EVR-ABD). Design. Retrospective analysis of prospectively collected data from patients undergoing EVR-ABD between January 1997 and December 2004. Methods. EVR-ABD was performed in 31 patients (20 males, median age 74. years (IQR: 64-79)). Indications for treatmen

I december 2015 skrev den svenska regering under FN:s Agenda 2030 bestående av 17 hållbarhetsmål med tillhörande 169 delmål. Mål 12, delmål 3 lyder: “Till 2030, halvera det globala matsvinnet per person i butik- och konsumentledet, och minska matsvinnet längs hela livsmedelskedjan, även förlusterna efter skörd.” Att fullt ätbar mat slängs belyser alla tre aspekter av begreppet hållbarhet på ett efIn 2015 the Swedish government signed the UN Agenda 2030 comprising of 17 Sustainable Development Goals and a total of 169 sub targets. Goal 12 target 3 reads as follows: “By 2030, halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses.” Wasting eatable food effectively highlights all three param

Från giftiga potatisar till användbara proteiner Potatis är en av världens mest odlade grödor. Den innehåller både kolhydrater och proteiner och har ett högt näringsvärde. Det talas ofta om att det är viktigt att få i sig proteiner, men sällan om proteinets emulgerande, konsistengivande och skummande egenskaper. Dessa egenskaper är högt värderade inom livsmedelsindustrin. Traditionell odling harPotato protein is an industrial side product with highly desirable properties which can be utilized if the toxic glycoalkaloids can be removed in a gentle way which doesn’t damage the protein. The challenge within this project is to find an extraction technique efficient enough to remove the toxic glycoalkaloids, but still mild enough to preserve the protein from denaturation. Supercritical CO2 ex

Since its inception, Estonia has been at the forefront of innovation in terms of e-governance and applications of online systems into various aspects of Estonians’ lives. In 2014 Estonia opened up it’s digital borders and launched a digital economic citizenship - e-Residency - available to anyone in the world for using Estonian e-services to register and manage a company online. In May 2018, 5000

Guardian proteins help or hinder clumpy proteins? Proteins are products encoded by DNA in cells. They need to be folded in a certain structure to perform their function in the cell. Because of this, the proteins need a quality control system to ensure that they are folded correctly. A large group of proteins called as chaperones are important in this regard. The main role of chaperones is to fold

Med sin ökade tillgänglighet på den kommersiella marknaden har eye-tracking blivit ett allmänt tillgängligt system för att analysera ögonrörelser. Detta har öppnat upp för nya möjligheter för utvärdering av usability inom humancomputer interaction, som tidigare har varit dyrt, tidskrävande och ofta utfört baserat på dåligt dokumenterade standarder och mål. Tidigare forskning har visat att eye-tracWith its increased availability on the commercial market, eye-tracking has become a widely accessible system for analysing eye-movements. This has opened up new possibilities in evaluation of usability in human-computer interaction, which has had a history of being expensive, time-consuming and often performed based on poorly documented standards and objectives. Previous research has indicated the

Aktivt kol har identifierats som en av de mer effektiva metoderna när det kommer till att avlägsna organiska mikroföroreningar (OMF) från avloppsvatten. Aktivt kol är ett poröst material med stor ytarea som kan adsorbera andra ämnen. Det är inget som existerar naturligt utan behöver framställas. Framställningen kan ske från i princip vilket material som helst som har en hög kolhalt. En stor del avActivated carbon has been identified as one of the more effective methods of removing organic micropollutants (OMP) from wastewater. Activated carbon is a porous material with a large surface area that allows adsorption of other substances. The material does not exist naturally and therefore has to be produced. The production can be done from any carbon-rich material and today the precursor is mai
