Energy conservation and pomeron loops in high energy evolution

We present a formalism which modifies the Mueller Dipole Model such that it incorporates energy-momentum conservation and also important colour suppressed effects. We implement our formalism in a Monte Carlo simulation and compare the results to inclusive data from HERA and the Tevatron, where we see that there is a good agreement between the data and our model.

Fusion of the HMGA2 and NFIB genes in lipoma

The major cytogenetic subgroup of lipomas is characterized by aberrations of chromosome segment 12q13-15, which recombines with a large number of other chromosomal regions. The gene HMGA2 is the main target in these aberrations. For some recurrent rearrangements, chimeric transcripts, including the 5' part of HMGA2, have been described. The 3' partners identified are LPP, LHFP, CMKOR1, and EBF. In

Muntlig framställning i årskurs 5: utveckling av kriterier för bedömning

The study is based upon material which is a part of the Swedish Agency for Education's evaluation of oral production in year five at primary school. The overall aim of this study is to examine w h a t is assessed by describing the childrens speech, developing and testing criteria for the proficiency in speech in relation to this assessment. For qualitative purposes, a description of the phenomenon

Isocyanates - assessment of human exposure

Isocyanates are used mainly for manufacturing of polyurethane (PUR) foams, lacquers, elastomers and glues. The production of PUR exceeds 2 million tonnes per year and is increasing. Occupational exposure to isocyanates are associated with respiratory disorders. A method based on liquid chromatography mass spectrometry (LC-MS) was developed for the simultaneous determination of isocyanates, aminoi

Tire Modeling and Friction Estimation

New system technologies are continuously improving the performance of vehicles regarding comfort, stability, environmental stresses, and safety. Novel sensors are developed and used together with advanced control algorithms and faster and more accurate actuators to help the driver to maneuver the vehicle in a safer way. The physical traction limit set by the friction between the tires and the road

Hormone-sensitive lipase in skeletal muscle: regulatory mechanisms.

AIM: The enzymatic regulation of intramuscular triacylglycerol (TG) breakdown has until recently not been well understood. Our aim was to elucidate the role of hormone-sensitive lipase (HSL), which controls TG breakdown in adipose tissue. METHODS: Isolated rat muscle as well as exercising humans were studied. RESULTS: The presence of HSL was demonstrated in all muscle fibre types by Western blotti

Physical housing environment: development of a self-assessment instrument

The aims of this study were to construct and develop a self-administered assessment instrument, useful for studying clients' own perception of accessibility and usability in their housing environment, and to test the instrument for reliability. It was developed for use in combination with an objective, norm-based assessment of the physical housing environment, the Enabler instrument. The instrumen

Phosphorus Release by Fish in Relation to External and Internal Load in a Eutrophic Lake

The aim of this study was to compare the rate of phosphorus release from fish with estimates of external and internal load in the eutrophic Finjasjon, Sweden. Phosphorus release from roach and bream, when fed either benthic (Chironomidae) or pelagic (Daphnia) prey, was measured in laboratory tanks. These results were transformed to whole lake conditions by using calculated fish consumption rates o

Bosonic realizations of the colour Heisenberg Lie algebra

We describe realizations of the colour analogue of the Heisenberg Lie algebra by power series in non-commuting indeterminates satisfying Heisenberg's canonical commutation relations of quantum mechanics. The obtained formulas are used to construct new operator representations of the colour Heisenberg Lie algebra. These representations are shown to be closely connected with some combinatorial ident

Tissue reactions evoked by porous and plane surfaces made out of silicon and titanium.

Square-shaped silicon or titanium implants with plane or porous surfaces surrounded by a rim of silicone were implanted in the rat abdominal wall for evaluation of the tissue response after one, six, or 12 weeks. Cell damage was identified as increased membrane permeability using fluorescence microscopy by injection of propidium iodide prior to the killing of the rats. Capsule thickness and immuno

Performance of iterative CDMA receiver with channel estimation in multipath environments

Most works published on iterative CDMA receivers assume perfect channel knowledge or very simple channel models like the flat-fading channel. We want to extend the scope to multipath propagation scenarios and suggest an iterative scheme with channel estimation in the uplink of a chip-synchronous CDMA system. Channel estimates rely on pilot symbols and a posteriori probabilities on code bits of a S

The wood-decaying fungus Hygrophoropsis aurantiaca increases P availability in acid forest humus soil, while N addition hampers this effect

We evaluated the influence of the brown rot fungus Hygrophoropsis aurantiaca on P solubility in the humus layer of a podzolic forest soil. This fungus is known to exude large amounts of oxalic acid that may stimulate weathering of minerals and increase dissolution of humus, which in turn may increase P availability in the soil surrounding the fungus. Humus was inoculated using small wooden pieces

A microarray approach for identifying mutated genes

This study was performed to evaluate if microarray technology can identify genes using their transcriptionally defective mutant alleles. Three barley (Hordeum vulgare L.) mutant strains, xantha-h57, xantha-f27 and xantha-g28, with mutations in the genes encoding the three subunits of the chlorophyll biosynthetic enzyme magnesium chelatase, were used in a reconstruction experiment. The mutation xan

Short hospital stay augmented with education and home-based rehabilitation improves function and quality of life after hip replacement - Randomized study of 50 patients with 6 months of follow-up

Background Because of current cost restrictions, we studied the effect of a shorter hospital stay on function, pain and quality of life (QOL) after total hip replacement (THR). Patients and methods 50 patients from two hospitals were randomized into a study group (SG) of 27 patients receiving preoperative and postoperative education programs, as well as home visits from an outpatient team, and a c
