Studies of institutional transformation in science have largely overlooked Big Science installations, despite far-reaching changes to the roles and functions of such large labs in the past decades. Here, we present and analyze two Big Science labs that have undergone profound transformations from single-purpose particle physics labs to multi-purpose centers for so-called photon science: SLAC in th
The properties of modified cellulose polymers, such as methylcellulose, are significantly influenced by the distribution of substituents along the polymer backbone. This distribution is difficult to determine due to the lack of suitable analytical methods. One approach is to use cellulose-degrading enzymes to gain information from the capability of the enzymes to cleave the bonds between glucose u
Popular Abstract in Swedish Avhandlingen behandlar tre områden: 1. implementeringen av Multisystemisk terapi (MST) som en behandlingsmetod inom socialtjänsten i Sverige, 2. implementeringen av ett forskningsprojekt vars mål är att utvärdera MST som behandlingsmetod, 3. utvärdering av MST som behandlingsmetod i jämförelse med traditionell behandling inom socialtjänsten för antisociala ungdomar. StuThis thesis focuses on three areas: 1. the implementation of Multisystemic Therapy (MST) as a treatment method in social services in Sweden, 2. the implementation of a research project that has the aim to evaluate MST as a treatment method, 3. the evaluation of MST as a treatment method compared to traditional social services for antisocial adolescents in Sweden. The first study reports on the imp
This study examined lip and tongue kinematics in stop and fricative consonants of different durations. Native speakers of Japanese served as subjects. An analysis of the lower lip closing movement indicated that it differed for the long and short labial consonants. In particular, the lower lip reached its highest vertical position later during the closure for the long than for the short consonants
Popular Abstract in Swedish Studier av enstaka makromolekyler gör det möjligt att få insikt i och karakterisera viktiga biologiska processer. DNA, livets molekyl, är av särskilt intresse här. I denna avhandling användar vi metoder från statistisk fysik för att studera olika aspekter av DNA i nanokanaler och dess smältegenskaper. DNA-smältning är inte bara relevant för förståelsen av denna molekylsInvestigation of single macromolecules makes it possible to gain insight into and characterize important biological processes. DNA as the molecule of life is of special interest here. In this thesis tools from statistical physics are used to study different aspects of DNA confined to nanochannels, with particular regard to its denaturation properties. The study of DNA melting from the theoretical
Hydrogen has been proposed as a possible fuel for automotive applications. Methanol is one of the most efficient ways to store and handle hydrogen. By catalytic reformation it is possible to convert methanol into hydrogen and carbon monoxide. This paper reports an experimental investigation of Reformed Methanol Gas as Homogeneous Charge Compression Ignition (HCCI) engine fuel. The aim of the exper
It is expected that fuel cells will play a significant role in a future sustainable energy system. They are energy efficient, fuel can be produced nearly locally and, when a renewable fuel such as ethanol, methanol and biogas is used, there are no net emissions of greenhouse gases. Fuel cells have during recent years various progresses, but the technology is still in the early phases of developmen
Popular Abstract in Swedish "Män födda 1914" är en studie som påbörjades 1982 för att studera hjärt- och kärlsjukdomar. Studien bedrivs vid Institutionen för samhällsmedicin vid Universitetssjukhuset MAS. Alla män, födda jämn månad 1914 och bosatta i Malmö, inbjöds att deltaga. Totalt inbjöds 621 män, då 68 år gamla, och av dessa deltog 500. Då man jämförde deltagare med icke-deltagare kunde man k"Men born in 1914" is a prospective cohort study on the epidemiology of cardiovascular disease. The study is run by the Department of Community Medicine, Lund University, Malmö. Five hundred men participated in the study when it started with a baseline examination in 1982/83. The men were then 68 years old. The psychological part of the study included tests of cognitive function and the serial Col
