Popular Abstract in Swedish Den här avhandlingen behandlar däggdjurens systematiska släktskap. Olika metoder och dataset har använts och utvecklats för att besvara systematiska frågeställningar på olika nivåer. Genom statistiska analyser av nukleotid och/eller aminosyra sekvenser från olika arters gener har deras evolutionära släktskap fastställts. Släktskapet inom moderkaksdäggdjuren har undersöIn this thesis, the phylogenetic relationships of the Mammalia have been studied at various levels. Different sources of genetic information have been evaluated and used as phylogenetic markers. These include the well-known mitochondrial genome, cDNA from housekeeping genes and expressed sequence tags from nuclear genes. Applying RT-PCR on mRNA from nuclear genes is a new approach for collecting

Different hadronization effects in high energy interactions are investigated. The frame-work is the Lund model for the strong interaction. A model for baryon production in jet fragmentation is presented and extended to baryon remnant fragmentation in deep inelastic scattering and hadron--hadron collisions. Observables designed to probe hadronization effects on pt correlations are shown to be sen

Vem var egentligen Erving Goffman – och hur viktig var hans insats som sociolog? Goffmans teori om social interaktion har blivit alltmer populär efter hans död – men under sin livstid var han omstridd, motsägelsefull och lite gåtfull. Boken utgör både en introduktion till och en tolkning av Goffmans perspektiv på social interaktion. Den är också ett försök att utveckla perspektivet på några vitala

Computerization of control room functions changes the work for the operators to a great extent. Their mental picture of the process, their possibilities to control the process for productivity and quality, the work content, the physical and the social working environment are examples of conditions which are changed one way or another. In order to be able to control the computerization process in a

Popular Abstract in Swedish Immunsystemet är vårt skydd mot främmande organismer såsom bakterier och virus. När vi får en förkylning, eller en infektion, tar immunsystemets celler hand om och dödar de invaderade mikroorganismerna. I normala fall märker vi endast av detta i form av att vi känner oss sjuka med eventuell feber som följd. Det ställs stora krav på immunsystemet. Det ska inte bara kunnaCollagen-induced arthritis (CIA) and pristane-induced arthritis (PIA) are animal models for human rheumatoid arthritis (RA), and can be induced in susceptible mouse and rat strains. CIA is induced by immunization of type II collagen (CII), a cartilage specific protein together with Freund’s adjuvant. PIA is induced by intradermal injection of pristane (2,6,10,14-tetrametylpentadecane). In rats, in

Disturbance rejection is a primary objective in many industrial control loops, thus a relevant goal for autotuning controllers. Nonetheless, autotuning has invariantly to cope with a reduced amount of process information. As a consequence, with the standard single-loop structure typically adopted in the addressed context, effective disturbance rejection calls for strong feedback, and therefore the

This paper presents a novel memory optimization technique to exploit the analogy between correlation coefficients in MMSE-based channel estimators across multiple standards. The need for coefficient storage for robust MMSE channel estimators is expensive in terms of on-chip memory. Besides, the memory requirements grow linearly by integrating more standards onto one platform. Thus, it becomes inev

Energy efficiency ex-ante policy evaluation is commonly, but not exclusively, concerned with the simulation and modelling of policy instruments and resulting technological change. Using the residential sector as case study, the paper provides a meta-analysis of models and modelling exercises and scrutinise their relevance for the field of energy efficiency policy evaluation. The methodology of stu

This paper describes new simple tuning rules for design of feedforward compensators. The problem of feedforward from load disturbances is analyzed, and it is shown that the feedback controller should be taken into account in the feedforward design process. Simple rules based on IAE minimization with restrictions on the process output overshoot and the high-frequency gain of the compensator are the

Popular Abstract in Swedish Beräkningar av högre ordning i kiral störningsteorin med tre kvarkar presenteras. De relevanta frihetsgraderna i denna teorin är de lättaste pseudo-skalära mesonerna, pionen och kaonen. Syftet med dessa beräkningar är dubbelt. För det första, att kunna bestämma de erforderliga lågenergi-konstanter som krävs för att uppnå högre precision i förutsägelserna från denna teorHigher orders calculations of processes involving the pion and kaon pseudo-scalar mesons are presented in the framework of three flavour Chiral Perturbation Theory. The purpose is two-fold. First determining the low energy constants of ChPT that are necessary for higher accuracy predictions. Secondly, testing the validity of the chiral expansion in the strange quark mass, with emphasis on the valu

I will start out with an overview of common assumptions on the impact of free trade on the environment – assumptions which, very much like the first part of Lamy’s statement, are all-encompassing and deterministic. From there, I will narrow down the scope of examination to specific and immediate hardware-to-hardware impacts: akin to the second part of the above statement, the emphasis shall be put

This paper studies the impact of railroads on town-level growth in Sweden over 150 years. Our analysis builds on the fact that railroads historically were extended quasi-randomly across towns. Towns that gained access to a rail connection grew larger relative to other towns, with large negative spillovers on unconnected nearby towns. Over the 20th century, we find little adjustment to the initial
