The problem of identifying jets at CERN LEP and DESY HERA is studied. Identification using jet energies and fragmentation properties is treated separately in order to investigate the degree of quark-gluon separation that can be achieved by either of these approaches. In the case of the fragmentation-based identification, a neural network is used, and a test of the dependence on the jet production
The brainstem origin of preganglionic fibers to the sphenopalatine ganglion in rat was revealed by the aid of the retrograde axonal tracer True Blue (which does not traverse to a second order neuron) applied deep in the sphenopalatine ganglion or the Vidian nerve on one side. The majority of fibers originate in the ipsilateral lacrimo-muconasal nucleus in the ventrolateral rostral medulla oblongat
The aim of this study is to discuss the production, use, and interpretation of a group of decorative interior textiles during the period 1750–1950 belonging to the County Museum in Halmstad. Questions guiding the investigation are: How did production take place? How were the textiles used in different times and places? How have the textiles been interpreted and what effects have different interpre

Different studies on the stability of high density lipoprotein cholesterol (HDL) in frozen serum or plasma have yielded conflicting results, namely increase, decrease, or no change at all during prolonged storage under freezing conditions. As part of a major trial on lipid-lowering strategies we statistically demonstrated a time-related decrease in HDL cholesterol during storage up to 46 months at
Multinuclear pulsed field gradient NMR measurements and theological viscosity measurements were performed on three series of polymer gel electrolytes. The gels were based on a lithium salt electrolyte swollen into a copolymer matrix comprising an acrylate backbone and ethylene oxide side chains. In each series the side chains differed in length and number, but the acrylate-to-ethylene oxide ratio
Denna avhandling tar upp frågan om det epistolografiska formuläret, genrefrågan, den retoriska dispositionen i Galaterbrevet samt sammanfattar på ett bra sätt resultaten. Bokens titel antyder redan huvudresultatet av undersökningen, nämligen att själva den yttre formen har större betydelse för budskapet än man vanligtvis tillmäter denna. Och här är det alltså fråga om den epistolografiska som man This dissertation handles the question of the rhetorical formula, the genre and the rhetorical disposition of Galatians. There is also an excellent summary with further perspectives. The title of the book already gives a glimpse of the main result, namely that the form has more bearing on the message than usually acknowledged. Here it is the question of the epistolographical form which often is tr
Water extracts of the bark of Uncaria tomentosa, a vine indigenous to South America, has been used for generations as an "immuno modulator". To understand the basis of this immuno modulatory effect we fed mice in their drinking water with C-Med 100, which is a commercially available water extract from Uncaria tomentosa. We found a dose-dependent increase in spleen cell numbers in the supplemented
Gamma rays from the reaction Si-28(Ni-58, 3p)83Y at a beam energy of 195 MeV were recorded in recoil-gamma- and gamma-gamma-coincidence mode with the POLYTESSA array and the Daresbury recoil mass separator. The known rotational bands were extended up to probable spins 49/2+ and 45/2-; many new interconnecting dipole transitions and an additional cascade were established. The bands are interpreted
A laboratory study on the sublethal effects of cadmium (Cd) on the net-spinning process of the larvae of Hydropsyche slossonae was conducted in order to assess the potential of net anomalies as an indicator of chronic exposure to Cd. Two major anomalies with different frequency levels were identified after chronic exposure to 0.37, 1.2, 11.6, 21.4 and 43.3 μg l−1 of Cd. The first was a distortion
Endoderm development is an area of intense interest in developmental biology, but progress has been hampered by the lack of specific markers for differentiated endodermal cells. In an unbiased secretion cloning screen of Xenopus gastrula embryos we isolated a novel gene, designated Darmin. Darmin encodes a secreted protein of 56 kDa containing a peptidase M20 domain characteristic of the glutamate
Regeneration of cells in the central nervous system is a process that might be affected during neurological disease and trauma. Because nitric oxide (NO) and its derivatives are powerful mediators in the inflammatory cascade, we have investigated the effects of pathophysiological concentrations of NO on neurogenesis, gliogenesis, and the expression of proneural genes in primary adult neural stem c
Low-energy particle production perpendicular to the event plane in three-jet events produced in Z decays in e(+)e(-) annihilation is measured and compared to that perpendicular to the event axis in two-jet events. The topology dependence of the hadron production ratio is found to agree with a leading-order QCD prediction. This agreement and especially the need for the presence of a destructive int
In Swedish public debate, economists have been more influential than any other category of social scientists. We examine the views of five great Swedish economists on the role of the university economist in the public arena. What did they say about scholarly objectivity and value judgements, about political commitment and educating the people? The five economists are Knut Wicksell, Gustav Cassel,
A novel process for the production of biodegradable lubricant-based stocks from epoxidized vegetable oil with a lower pour point via cationic ion-exchange resins as catalysts was developed. This involves two steps, first, ring-opening reactions by alcoholysis followed by esterification of the resultant hydroxy group in the first step. The ring-opening reaction of epoxidized soybean oil with differ
In the first essay of this thesis we develop a model for calculating the net expected value of a swap agreement subject to dual-default risk. The main explanatory variable for the net expected return of a swap is the default intensity of each party measured by the credit rating of the firm. We derive the net expected return of the swap as a function of the credit rating of the firm receiving the f
