In the present work surface thermometry using a method based on the spectroscopy of inorganic luminescent material has been applied in a full-size aircraft jet engine. The technique utilizes laser-induced emission from thermographic phosphors for, non-intrusive, remote temperature diagnostics in combustion applications with high sensitivity and accuracy. In the present application the laser-induce

There is a great potential for phasor measurement applications in Scandinavia, mainly due to the long distance power transmission and limited transmission capacity expansion possibilities. Smart control, based on phasor measurements, can be used as an alternative to additional transmission lines, to increase power transmission capacity. Also the matter of damping is more and more becoming a key is

Popular Abstract in Swedish Enligt ordboken betyder störning något som är avvikande från det normala. I den ekologiska begreppsvärlden är det tvärtom en del av det normala. Störning är en förutsättning för att många kulturmarker med hög biodiversitet ska kunna skapas och bevaras. I denna avhandling undersöktes hur markstörning i form av plöjning och harvning i torra gräsmarker påverkar mångfalden

Popular Abstract in Swedish I Sverige produceras dagligen flera ton biprodukter avfall inom jordbruks-, livsmedels- och skogsindustrierna. Detta avfall förbränns, komposteras och går till biogasproduktion samt i vissa fall till djurfoder. Intressanta avfallsgrupper ur ett svenskt perspektiv är lök- morots-, och potatis avfall från jordbruk- och livsmedelsindustrin och bark från skogsindustrin. DesThe word sustainability is more and more frequently used within the field of chemistry and in many other fields. Green or sustainable chemistry was introduced during the 90 ́s as a field of chemistry where the environmental and health impacts of processes and products are evaluated and improved. Within analytical chemistry the awareness of sustainability has also increased, which has resulted in o

The distribution of extraterrestrial chromite grains (> 63 mu m) has been studied in the resurge deposit of the early Late Ordovician (458 Ma) Lockne impact structure in central Sweden. A 1-kg-sample of resurge sediment from the rim of the crater is extremely rich in extraterrestrial chromite. In total the sample contains > 125 chromium spinel grains kg(-1), most grains being chromite. Due to post

The object of this thesis is to describe, analyze and understand the terms and meanings of the public information and the political communication for local democracy, in today´s media landscape, out of the interaction between the main parties of the local society in Sjöbo and Ystad and from the stand point of earlier research and theories. The study has analyzed the actions performed by citizens,

In healthy individuals, the ability of the pancreatic islets to sense and respond appropriately to changes in plasma glucose levels maintains plasma glucose levels within a narrow range despite broad fluctuations in nutrient intake and variable "demand" for insulin imposed by changes in insulin sensitivity. This ability of the pancreatic islets is lost in type 2 diabetes (T2DM). For studies on the

The biotechnology industry has grown considerably over the past twenty years, and the revolution within the field of molecular biology has dramatically improved the possibilities of producing proteins and other important biomolecules. The product of interest will be obtained in a multi-component solution and some challenging purification work has to be performed to recover the target molecule in a

Popular Abstract in Swedish I den här avhandlingen behandlas olika aspekter av gelfria metoder för proteomanalys med masspektrometri, med tonvikt på inmärkningsmetoder. Arbetet är baserat på tre artiklar, där olika effekter vid inmärkning på peptider utreds, samt framtagningen av en ny typ av inmärkningsstrategi beskrivs. Kemisk inmärkning har haft stor betydelse för peptidbaserad proteomik eftersIn this thesis different aspects of gel free procedures for mass spectrometry based proteome analysis are addressed, with emphasis on labelling techniques. It is based on three original articles where the effects imposed onto peptides upon modification are investigated, and the development of a new type of labelling strategy is described. Chemical modification has been of great importance for the

Popular Abstract in Swedish Egenskapsorienterade system (eng: property-oriented) är en ny slags informationssystem som är baserade på begrepp för egenskaper istället för begrepp för ting eller klasser av ting. Genom att fokusera på egenskaper, kan de egenskapsorinterade systemen göras mer flexibla och mer lämpade för de tidiga skedena av design än de traditionella klassorienterade systemen kan varProperty-oriented systems are a new kind of information systems that are based on concepts of properties instead of concepts of things or classes of things. By focusing on properties, the property-oriented systems become more flexible and more suited to the dynamic early stages of design than the traditional class-oriented systems can be. The theoretical framework for property-oriented systems de

Popular Abstract in Swedish Vår värld drivs av förbränning. Från den lilla elden som används vid matlagning till gigantiska gasturbiner och kolkraftverk som genererar en stor del av all elektricitet. Dessutom så drivs nästan alla fordon av förbränningsmotorer. Det har uppskattats att över nittio procent av alla energi vi i världen omvandlar kommer från förbränning i någon form. Det är således ganHigh repetition rate laser diagnostics has proven to be a useful tool for studying combustion phenomena. Laser techniques are, in general, relatively non-intrusive and have the potential to measure specific species at very low concentrations and with extremely high temporal resolution. However, most laser systems in this field of research are limited to repetition rates below 100 Hz, and are thus

The neurons in the ventral mesencephalon (VM) are organized into several nuclei consisting of distinct neuronal populations. These include the dopaminergic (DA) neurons of the substania nigra and ventral tegmental area, the oculomotor (OM) neurons that innervate the muscles controlling eye movement, and the reticular neurons of the red nucleus (RN) involved in motor control and coordination review

The deactivation of a commercial selective catalytic reduction (SCR) catalyst of type V2O5−WO3/TiO2 has been studied in this work through comparisons of results from a full-scale biomass combustion plant with those from laboratory experiments. In the latter, the catalyst was exposed to KCl, K2SO4, and ZnCl2 by both wet impregnation with diluted salt solutions and deposition of generated submicrome

Objective. The aim of this prospective study is to assess the effect of liposuction on the pain experienced by women with Dercum's disease (adiposis dolorosa). Design. Pain was examined preoperatively and at 3 months, and 1, 2, 3, and 5 years after liposuction. The subjective pain sensation was evaluated with a visual analog scale and number of words chosen, and the objective pain sensation with t
