A derivation for a polarized CCFM evolution equation which is suitable to describe the scaling behavior of the unintegrated polarized gluon density is given. We discuss the properties of this polarized CCFM equation and compare it to the standard CCFM equation in the unpolarized case.

Popular Abstract in Swedish Avhandlingen behandlar två områden. Dels kopplingen mellan import, konkurrens och produktivitetsutveckling i Sverige och inom EU, dels effekten av inrättandet av så kallade exportzoner i u-länder, det vill säga särskilda områden som omfattas av olika incitament för att locka utländska företag att etablera en exportorienterad verksamhet i landet. Exempelvis så kan tullfrThis thesis addresses empirically the interplay among international trade, foreign direct investment (FDI) and domestic market conditions, and its impact on competition, growth, exports and technology diffusion. Chapter two considers the potential relation between regional integration and productivity growth for the case of the European Union (EU). It is found that imports from other members is po

Our everyday appliances ranging from toys to vehicles, as well as the equipment used to manufacture them, contain an increasing number of embedded computers. Embedded software often implement functionality that is crucial for the operation of the device, resulting in a variety of timing requirements and resource utilization constraints to be fulfilled. Industrial competition and the ever increasin

The dut gene, which encodes Eseherichia coli deoxyuridine 5'-triphosphate nucleotidohydrolase (dUTPase), has been recloned to increase overexpression of the enzyme and to enable simplification of the purification protocol into a one-step procedure. The gene was cloned into the vector pET-3a and expressed in E. coli BL21(DE3) pLysS under the control of a bacteriophage T7 promotor. Induction results

Net ecosystem productivity (NEP) was studied in a bog located in the middle taiga of Siberia using two approaches, the accumulation of peat above the hypocotyl of pine trees, and the eddy covariance flux methodology. NEP was 0.84 tC ha-1 yr-1 using the peat accumulation method; it was 0.43–0.62 tC ha-1 yr-1 using eddy covariance over three growing seasons. These data were compared with NEP of the

Popular Abstract in Swedish Syftet med avhandlingen var att utarbeta en vård- och omvårdnadsmodell som förbättrar livskvalitet och hälsa hos svenska kvinnor med Irritable Bowel Syndrome (IBS). Avhandlingen består av 4 delstudier: Delstudie 1. Kvinnor med IBS upplevelse av en god livskvalitet. Delstudie 2. Utbildning av kvinnor med IBS. Delstudie 3. Hälsoaspekter i relation till användandet av Irritable Bowel Syndrome (IBS) is a common, worldwide, functional disorder affecting a significant number of people, predominantly women. Etiology and pathophysiology is insufficiently understood, but the research over the past decade has led to progress in the understanding of IBS, and it is generally accepted that the symptoms of IBS are multidetermined. However, management of IBS is still a cha

As ascites is related to liver cirrhosis in 80% of the patients, the present therapeutic guidelines are focused on ascites in liver cirrhosis. A combination of spironolactone and furosemide is recommended as first line therapy in patients with mild to moderate ascites and is effective in 90% of patients. In patients with pronounced or tense ascites, first line treatment is total paracentesis with

Antithyroid treatment for Graves' hyperthyroidism restores euthyroidism clinically within 1-2 months, but it is well known that TSH levels can remain suppressed for many months despite normal free T(4) and T(3) levels. This has been attributed to a delayed recovery of the pituitary-thyroid axis. However, we recently showed that the pituitary contains a TSH receptor through which TSH secretion may

Popular Abstract in Swedish I denna avhandling har användbarheten av Virtual Reality (VR) utvecklats och undersökts för två användningsområden: participatorisk design av arbetsplatser och hjärnskaderehabilitering. Inom det första användningsområdet används VR tillsammans med fullskalemodellering, drama och demokratisk mötesteknik i en Visualiseringsverkstad. Denna arbetsmetod har utvecklats och tIn this thesis, the usability of Virtual Reality (VR) has been investigated and developed within two applications: participatory design of workplaces and brain injury rehabilitation. In the first application, VR is used in combination with full scale modelling, drama and democratic meetings in an Envisionment Workshop. This workshop has been developed and tested through several real workplace int

OBJECTIVE: To determine the diagnostic value of metaiodobenzylguanidine (MIBG) scintigraphy compared with computed tomography (CT) for the localization of phaeochromocytomas in clinical practice. DESIGN: Retrospective comparison between MIBG scintigrams and CT for localization of phaeochromocytomas in all patients successively examined with MIBG scintigraphy in Malmo from 1984 until January 1997.

Investigation of photoinduced processes in different C60–Sn nanostructures excited by 150 fs laser pulses at 400 nm (109 W/cm2) was performed with femtosecond supercontinuum probing of difference absorption and reflection in the spectral range of 400–1600 nm. The dynamics of relaxation are quite different for various nanostructures depending on the deposition mode and the ratio of tin and fulleren

Hummingbird hawkmoths were tested for their preferences for different types of sugar. In triple choice tests, moths sucked for longer periods from sucrose than from fructose and glucose. Naive moths released in a large flight cage and monitored over 24 days, drank on average 137 mul sucrose, 67 mul fructose and 7 mul glucose daily. In an independent test, moths spent more time feeding from sucrose

Primary systemic vasculitis is associated with a high mortality if left untreated and it is essential to make the diagnosis before permanent organ damage has occurred. In this thesis the diagnostic and prognostic significance of anti-neutrophil cytoplasmic antibodies (ANCA) in systemic vasculitis is investigated. The clinical significance of a capture enzyme-linked immunosorbent assay (ELISA) bas
