Gasoline partially premixed combustion (PPC) has the potential of high efficiency and simultaneous low soot and NOx emissions. Running the engine in PPC mode with high octane number fuels has the advantage of a longer premix period of fuel and air which reduces soot emissions. The problem is the ignitability at low load and idle operating conditions. In a previous study it was shown that it is po

The law (1988:870) concerning care of substance abusers is constructed in a way that gives the social workers room to interpret and apply the law individually. This may contribute to differences in treatment between female and male substance abusers. The purpose of the essay was to investigate whether the client's gender had any significance to how the social worker interpret and apply the law

Predatory pricing is one of the most frequently discussed topics in competition law and should be considered both from a legal and economic perspective. The concept of predatory pricing can be described as a situation where a company is pricing at a level that, according to the assessment theories, is unreasonably low. The problems with this type of conduct arises when the low prices hinder compet

Populärvetenskaplig sammanfattning: Naturbetesmarkerna minskade med 86,7% från 1927 till 1990. Denna minskning är alarmerande eftersom många idag hotade och sällsynta arter är beroende av dessa. En stor del av anledningen till detta är att staten ända in på 1980-talet i sin rådgivning danade för att dessa marker antingen skulle bearbetas med konstgödsel och ogräsbekämpning eller planteras med trädThe rural landscape of Sweden has changed rapidly during the 20:th century. Measurements from 1927 compared to those from 1990 show that the area of non managed pasture in Sweden has declined by 86.7 %. Since a lot of threatened and rare species are dependent of this kind of land, these figures are alarming. During the last 30-40 years non managed pasture has declined due to abandonment, tree plan

This essay aims to examine and compare the attitudes of decision makers in the local government and representatives of pensioners in two different geographic areas. The main questions were: - their attitudes towards the "stay home principle" (kvarboendeprincipen, a principle that aims to make it possible for people with a handicap, disease or age to stay in their homes instead of moving

Corporal punishment of children is a widespread practice across the world. The implications of such violence consist of both physical and mental injuries and children are very vulnerable to such treatment. The Convention on the Rights of the Child was put into place, by States from all across the world, for the purpose of granting children a better protection in society. Today, all but two States

The purpose of this study was to examine the nursing auxiliaries’ experiences before, during and after the implementation of Alsterbromodellen. The implementation of Alsterbromodellen meant that home care staff and residential care staff got consolidated and performed the same tasks. More specifically the aim was to find out how Alsterbromodellen has made an impact on the nursing auxiliaries’ work

The aim of this study was to evaluate how the fixed furniture dimensions match with students' anthropometry and to describe head, upper back and upper limbs postures and movements. Evaluation was performed in 48 students from a Brazilian state school. Furniture dimensions were measured with metric tape, movements and postures by inclinometers (Logger Tecknologi, Akarp, Sweden). Seat height was hig

Artificial neural network (ANN) ensembles have long suffered from a lack of interpretability. This has severely limited the practical usability of ANNs in settings where an erroneous decision can be disastrous. Several attempts have been made to alleviate this problem. Many of them are based on decomposing the decision boundary of the ANN into a set of rules. We explore and compare a set of new me

This study was performed using daily spot prices, from January 1997 through July 2004; of the three assets that constitute the crack spread i.e. crude oil, gasoline and heating oil - all listed on the New York Mercantile Exchange (NYMEX). Our objective has been to characterize the dynamics of the spread and subsequently create trading strategies to yield returns that surpass that of a passive appr

I have chosen to describe the way out of illness, from the individuals stricken with illness’ point of view.

In a long time homosexuality has been a taboo. During the last century the attitude to homosexual people in Sweden has changed, e.g. today homosexual couples can be proved for adoption. But there are still prejustices and negative attitudes left. Most of the people who discover that they are interested in people with the same sex start as a teenager to consider if they are homosexual or not. The t

Long-chain fatty acids (LCFAs) are internalized by receptor-mediated mechanisms or receptor-independent diffusion across cytoplasmic membranes and are utilized as nutrients, building blocks and signaling intermediates. Here we describe how the association of LCFAs to a partially unfolded, extracellular protein can alter the presentation to target cells and cellular effects. HAMLET (Human α-lactalb

Immobilizing biomolecules with retained functionality and stability on solid supports is crucial for generation of sensitive immunoassays. However, upon use of conventional immobilization strategies, a major portion of the biomolecules (e.g. antibodies) frequently tends to lose their bioactivity. In this study, we describe a procedure to immobilize human single-chain variable fragment (scFv) via g

OBJECTIVE: To study the relationship between smoking and chronic pain among people aged 65+ years. DESIGN: A cross-sectional study. SAMPLE: The study was carried out in 2011 and included a randomly selected (N = 2000, response rate 57%) sample of people aged 65 years and older, living in Sweden. MEASUREMENT: A postal questionnaire with questions about demographic data, living conditions, tobacco u

Objective: Rathke's cleft cysts are benign, embryological remnants in the pituitary gland. The majority of them are small and asymptomatic but a few may become large, and cause mass effects, pituitary hormone deficiencies and visual impairment. Recommendations for the follow-up of Rathke's cleft cysts vary since data on the natural history are sparse. Patients and Design: Data at diagnosis and at
