This article presents a mechanical cutting force model for multi-tooth cutting processes, where initial position errors in radial and axial direction, eccentricity and edge wear are taken into account. The cutting forces are presented for each individual cutting edge, and in a system of coordinates where one axis is parallel to the cutting speed vector at any instant. The process parameter cutting

We describe an approach to screen large sets of MALDI-MS mass spectra for protein isoforms separated on two-dimensional electrophoresis gels. Mass spectra are matched against each other by utilizing extracted peak mass lists and hierarchical clustering. The output is presented as dendrograms in which protein isoforms cluster together. Clustering could be applied to mass spectra from different samp

In five patients with clinical suspicion of spinal disease, MRI of the spine revealed unexpected aortic pathology explaining the symptoms. No significant intraspinal pathology was found on MRI. However, in one patient with clinical suspicion of spinal stenosis, an aortic occlusion was detected on MR images of the spine. The lower extremity ischaemia, caused by the occlusion, was responsible for th

A previously undescribed human member of the cystatin superfamily called cystatin F has been identified by expressed sequence tag sequencing in human cDNA libraries. A full-length cDNA clone was obtained from a library made from mRNA of CD34-depleted cord blood cells. The sequence of the cDNA contained an open reading frame encoding a putative 19-residue signal peptide and a mature protein of 126

Water-soluble hemicelluloses were extracted from spruce chips by microwave heat fractionation. The chips were impregnated with water at different pH values. Screening of heat-fractionation conditions, i.e. impregnation medium, temperature and residence time was performed with the aim to extract O-acetyl-galactoglucomannan. The impregnation and heat fractionation conditions were evaluated on the ba

Data from ten Swedish-Arabic preschool children with language impairment and ten Swedish-Arabic children with normal language development matched for age and exposure to Swedish were analyzed. Specific tasks for both Swedish and Arabic were designed. By using the hierarchy predicted by processability theory as a yardstick, grammatical development was measured in the two languages of the children.

Objective: To develop calculation models, using Western immunoblot, as a tool for the estimation of proteolytic human aggrecan fragment identity. Method. Seven human aggrecan fragments (calibrators), purified by CsCl gradient centrifugation and identified by Western immunoblot of N- and C-terminals, were used to develop calculation models. The models were used for identification of unknown aggreca

This paper explores different syntactic variations and functional properties of clausal units that are initiated by the finite verb in Swedish. We focus on V1 constructions that are basically declarative in function, thus excluding interrogative, conditional and directive uses. Because V1 constructions, and particularly certain variants of them, are typical of spoken Swedish, our examples and

What is the relationship between ballot reforms and electoral malpractice? This article contributes to the growing comparative politics literature on the causes of election fraud in democratizing countries using the case of the 19th-century United States. We examine the adoption of the Australian ballot and disenfranchisement laws, and estimate their effects on multiple types of election fraud. Us

Drilling of a deep borehole does not normally allow for hydrologic testing during the drilling period. It is only done when drilling experiences a large loss (or high return) of drilling fluid due to penetration of a large-transmissivity zone. The paper proposes the possibility of conducting flowing fluid electrical conductivity (FFEC) logging during the drilling period, with negligible impact on

Glaciärer har visat sig vara känsliga för klimatologiska förändringar i sitt närområde och deras känslighet sträcker sig över flera olika tidsskalor. Glaciärerna har därför kommit att användas som indikatorer på både pågående och förhistoriska klimatförändringar. För att glaciärerna ska kunna spegla klimatet så krävs emellertid tillförlitliga mätmetoder av glaciärernas massa. I avsikt att återge g

Chemiluminescent emission from OH*, CH* and C2* radicals and its dependence on the equivalence ratio is being investigated in the current study. The aim of this project is to use the results for combustion control on marine vessels and safety checks. The study was conducted in collaboration with Kockumation, a leading company in developing control systems for running boilers and steam turbines on

The idea of fair trade is still widely debated. Yet, cities have since 2001 been able to apply for a Fairtrade City certification. In Sweden the initiative has been active since 2006 and today has 65 of its 290 municipalities certified. Proponents claim a municipalities needs to be involved while detractors se the concept as market intervention. The purpose of the thesis is to examine if there wer

Having access to family planning (FP) services is a cornerstone for economic and social development. Because of reproductive health disparities between income groups, progressive policies have been passed in the Philippines to reduce the gaps. One example is the Responsible Parenthood and Reproductive Health act that provides people living in poverty with FP services. Moreover, it attempts to prom

I dagens samhälle har det blivit allt vanligare att leva tillsammans utan att gifta sig och antalet sambor har ökat. Sambolagstiftningen bygger delvis på äktenskapslagstiftningen och de har således många likheter, men också många skillnader. Syftet med denna uppsatsen har varit att utreda huruvida makar och sambor bör jämställas ur ett rättsligt perspektiv genom att ha en gemensam lagstiftning istIn today’s society, it has become more and more usual to live together without getting married and the number of common law marriage has increased. The common law marriage legislation is partly based on the matrimony legislation and they therefore have a lot of similarities, but also a lot of differences. The purpose of this thesis has been to investigate if married couples and common law married
