This thesis is a summary of four papers concerning various aspects on the transition metal catalysed hydrosilylation of 1,3-dienes. The hydrosilylation reaction is formally an addition of a hydrosilane to an unsaturated system and depending on the reaction conditions, control of stereo-, regio-, and chemo-selectivity can be achieved. Optically active heterobidentate P,N ligands were synthesised f
Electrical machine production is a multi-disciplinary area, comprising traditional mechanical processes such as sheet metal cutting, chemical processes for insulation and electrical for the working principles. In manufacturing, high throughput automation of coilwinding and sheet-cutting is combined with complex assembly, such as slotting the coils, often performed manually, but with increasing int
In the first part of this thesis, measurement and registration procedures of occlusal interferences and their inter and intraobserver variability were evaluated. In the second part of this thesis, the short and long-term effect of occlusal adjustment therapy was prospectively assessed in a controlled clinical trial in a selected group of 50 patients with myogeneous craniomandibular disorders (CMD)
Short survey over the problems connected to the collection and preservation of experimental film
The need for keeping manufacturing and workplacesin Europe calls for new ideas and concepts for productiverobots with focus on their usefulness for Small andMedium sized Enterprises (SMEs). The activitiesfrom the Robotics Research at LTH, [3], [4], [2], andin particular those related to the SMErobot project[1] comprise efforts in this direction. The SMErobotproject is a recently started four-year-
The interfacial behavior of DNA and DNA-cationic surfactant has been studied. Particular attention was paid to the type of cationic surfactant and the DNA conformation (single or double stranded) as well as the DNA length. Adsorption of DNA-cationic surfactant complexes is determined by a delicate balance between the DNA-surface, cationic surfactant-surface, and cationic surfactant-DNA-solvent int
Liming increased species richness, in accordance with the species pool hypothesis, and number of plants of individual species in beech forest field-layer vegetation, by increasing establishment by seedlings and vegetative offspring. Turnover rates also increased, suggesting the explanatory value of the carousel model. Plant size, absolute measures of reproduction, and poportional measures of sexua
This thesis addresses: (1) studies of direct and mediated electron transfer and kinetics of peroxidases on electrodes and the development of amperometric peroxidase-based biosenors, (2) electrochemical and kinetic studies of NADH oxidation at mediator modified electrodes. The direct and mediated electron transfer of horseradish and tobacco peroxidase were investigated on graphite electrodes by us
Solen har lyst konstant på vår värld i fyra och en halv miljard år. Strålarna som värmer vår hud idag har känts av varenda person som någonsin levt. Solens strålar har rört vid dinosaurier, och hälsat på de första varelser som lämnade havens vatten för ett liv på land.Solen har varit vittne till allting som skett här på Jorden. Men den är ingen passiv iakttagare. Solen är vår planets kraftverk, deThe Sun has shone on our world for four and a half billion years. The light that warms our skin today has been felt by every person who has ever lived.It is our nearest star and our planet’s powerhouse, the source of the energy that drives our winds, our weather and all life.The passage of the Sun’s fiery disc across the sky — day by day, month by month — was the only way to keep track of time for
