Thermographic phosphors can be robust temperature remote sensors. The accuracy of the temperature measured by the phosphor is highly dependent on the quality of the phosphor calibration used. Conventionally, thermographic phosphors are calibrated by measuring a series of decay curves at known stable oven temperatures. The process is then repeated covering the thermal sensitivity range of the phosp

An introduction to the Swedish translation of St. Augustine's De doctrina christiana.

The purpose is to present a theoretical model of the concept employeeship. Employeeship concerns all employees and covers the vertical perspective of work behaviors and relationships between formal leaders and followers, and the horizontal perspective between co-workers on all organizational levels. This enables the study of both formal and informal leadership, authentically recognizing that all e

In a previous paper, we showed how classical ideas for dynamicprogramming in discrete networks can be adapted to hybrid systems. The approach is based on discretization of the continuous Bellman inequality which gives a lower bound on the optimal cost. The lower bound is maximized by linear programming to get an approximation of the optimal solution.In this paper, we apply ideas from infinite-dime

Popular Abstract in Swedish Immunsystemet består av en specifik och en ospecifik del som samarbetar när ett immunsvar sätts igång. Den specifika delen utgörs av T och B celler som med specifika ytreceptorer, så kallade antigen-receptorer, känner igen och aktiveras av främmande ämnen (antigen). För att T celler skall aktiveras av antigen, krävs det att dendritiska celler inom den ospecifika delen aImmunological self-tolerance is a state of the whole organism where deleterious responses are either avoided or regulated. Breaking of immunological tolerance will lead to autoimmune disease or chronic inflammatory conditions. T cell maturation in the thymus generates a peripheral T cell pool with an enormous TCR repertoire, from which specific T cells are selected and activated upon encounters wi

Following the recommendations drawn after the Commissioning Phase of the ENVISAT satellite in 2002, SCIAMACHY near real time data processors were upgraded to version 5.01 in early 2004. Before public release of the new SCIAMACHY nitrogen dioxide (NO2) vertical column data product, several validation teams investigated its improvement and assessed its geophysical consistency by means of correlative

The present work studies the separated flow in a square channel with ribs on one wall by using the PIV method. In this study, the spacing between ribs is kept constant and the heights of rib are varied in order to investigate the influence of the pitch-to-height ratio, P/e on the flow structures. Depending on the various pitch ratios, the enclosure between ribs can be regarded as closed or open ca

Place-names often reflect local, cultural, and political history. It is only natural, therefore, that words for such historically important phenomena as boundaries should form part of place-names. In England, there is a fair number of place-name elements that refer to boundaries. Some of them are treated in this thesis. They are OE (ge)mǣre, OE mearc, OE *rān, *rǣn(e), ON rein, ON rá, and OE hār.

Popular Abstract in Swedish När vi blir infekterade av virus eller bakterier (patogener) hjälper olika delar av vårt immunförsvar till att försvara oss från dem. Vår hud, slemhinnor, magsyra och vissa immunceller hjälper till att ospecifikt och snabbt hindra patogenerna från att angripa oss och ofta räcker detta för att infektionen skall klaras av. Men det finns en del till av vårt immunförsvar soT lymohocytes (T cells) and B lymphocytes (B cells) are important effector cells of the adaptive immune system. In response to infections, B cells are activated and produce antibodies against specific antigens. There are two types of T cells, cytotoxic T cells that kill cells infected with bacteria or viruses, and helper T (Th) cells that help B cells produce antibodies by secreting cytokines as w

Vitamin D was discovered due to its ability to cure rickets, but recently many other important functions for it in the human body have been discoverred, and it counteracts several other diseases, as diabetes and some forms of cancer. The nuclear vitamin D receptor has been found throughout the vertebrate phylum down to jawless fishes, but not in invertebrates. Its role in those organisms that are

Hipparcos observations of double stars, mainly A and F primaries, aremodelled in order to check the statistics of double-star solutions inthe Hipparcos Catalogue and to set quantitative limits on binarydistributions. The number of companions per primary is estimated to 0.25+/-0.05 for semi-major axes from 1 to 10 AU, and to 0.43 +/-0.20 for therange 10--100 AU. The total multiplicity found is betw

Attempts to measure social mobility before the twentieth century are frequently hampered by limited data. In this paper, we use a new source – annual, matched tax censuses over more than 70 years – to calculate intragenerational income mobility within a preindustrial, settler society, the Dutch and British Cape Colony at the southern tip of Africa. Our unique source allows us to measure income mob

Atherosclerosis, the underlying pathology of cardiovascular diseases such as myocardial infarction and ischemic stroke, is characterized by chronic inflammation. T cells are present in atherosclerotic plaques and have been implicated in its pathogenesis. This thesis describes studies exploring both the regulation of T cells in atherosclerosis as well as immunomodulatory therapeutics. To study the
