We present a novel Monte Carlo implementation of dynamic color screening via multiple exchanges of semisoft gluons as a basic QCD mechanism to understand diffractive electron-proton scattering at the HERA collider. Based on the kinematics of individual events in the standard QCD description of deep inelastic scattering at the parton level, which at low x is dominantly gluon initiated, the probabil
Are people more likely to become more politically active through social media when they observe that their friends are active? Previous research has shown that an individual's likelihood of engaging politically is influenced by observations of how friends act through social media, but relatively little is known about how such social influence through social media interacts with personality feature
We characterize the selection function of RAdial Velocity Experiment (RAVE) using 2 Micron All Sky Survey (2MASS) as our underlying population, which we assume represents all stars that could have potentially been observed.We evaluate the completeness fraction as a function of position, magnitude and colour in two ways: first, on a field-by-field basis, and second, in equal-size areas on the sky.
The enzymatic syntheses of 1-lauroyl-dihydroxyacetone and 1,3-dilauroyl-dihydroxyacetone were investigated. Lipase B from Candida antarctica (SP435) was used to catalyse the acylation of dihydroxyacetone (DHA) with lauric acid in organic solvent media at controlled water activity. High conversions of dihydroxyacetone (> 90%) are achieved when the water activity is 0.11 or below in solvents of vari
Propionibacterium acidipropionici produces propionic acid from different sugars and glycerol; the production can be improved by high cell density fermentations using immobilized cells that help to overcome the limitations of the non-productive lag phase and product inhibition. In this study, the use of stress factors to induce P. acidipropionici to form biofilm and its use as an immobilization pro
BACKGROUND: To investigate the value of combined treatment with allopurinol and 5-aminosalicylic (5-ASA) based drugs as maintenance treatment for ulcerative colitis (UC).METHODS: 199 patients with UC in remission but with active disease during the preceding 3 years were included. Allopurinol 100 mg twice daily or placebo was added to the 5-ASA based maintenance treatment. Clinical and endoscopic f
In a study with 108 10- to 12-year-olds who used a digital educational game targeting history, we addressed the phenomenon of perseverance, that is, the tendency to stick with a task even when it is challenging. The educational game was designed to make all students encounter tasks they did not succeed to solve, at which point they were offered a set of choices corresponding to perseverance and no
Many independent publishers are today offering digital libraries with fulltext archives. In an attempt to provide a single user-interface to a large set of archives, DTVs Article Database Service, offers a consolidatedinterface to a geographically distributed set of archives. While this approach offers a tremendous functional advantage to a user, the delays caused by the network and queuing delays
In this thesis I have investigated pauses in writing in word-internal contexts and clause boundaries. I have been looking at the differences between 15-year-olds and adults with dyslexia and been focusing on how many pauses and how much pause time they have in these contexts. People with dyslexia have difficulties coding words, which mean that they are bad spellers and readers. Normally we automat
This report contains a fire safety risk analysis of the X-ray Ward in the hospital in Värnamo. Värnamo hospital was built in 1976 and is today one of the biggest district hospitals in Sweden with approximately 1300 employees. A visit at the hospital was conducted in order to gain an understanding of existing fire hazards and risks on the site. All information gained during the visit was compiled a
The aim of this project was to investigate the effect of Lactobacillus plantarum 299v on the flocculating behaviour of beer starter culture yeast strains isolated from both top and bottom fermenting yeasts from a previous study (Li.Yu.,2014 unpublished). In the present study,microbial enumeration was done through basic culturing and plating techniques. Yeast strains and isolates of Lactobacillus p
Det har länge pågått diskussioner om hur Visingsögruppen blev avsatt. Målet med den här studien är att få mer insikt i sedimentens litologiska sammansättning, provenans och genom att sätta upp ett sekvensstratigrafiskt ramverk kunna definiera depositionsprocesser. Studien fokuserade på sediment som tillhör den Mellersta formationen i Visingsögruppen, belägna vid Näs, Visingsö, Sverige. Metoderna sThe depositional setting of the Neoproterozoic Visingsö Group has long been a subject of discussion. This study aims to provide additional insights into the lithological composition and provenance of the sediments and to provide a sequence stratigraphic framework in order to define the depositional setting. It focuses on rocks belonging to the Middle Formation of the Visingsö Group located at the
The aim of this study is to investigate human behavior during the pre-movement phase of building evacuation and determine how pre-movement time varies between different building types and types of alarms. Unannounced videorecorded evacuation experiments from earlier studies were examined, which resulted in 2 486 individual pre-movement times divided amongst six different building types. The parts
Malware are become increasingly aware of their execution environment. In order to avoid detection by automated analysis solutions and to obstruct manual analysis, malware authors are coming up with new ways for their malware to decide whether it should express its malicious behavior or not. Previous solutions to this problem focus on for example improving the stealth of analysis environments (to a
The purpose of this thesis is to analyse to what extent colonial trade patterns persist in former British and French colonies in Southeast Asia and West Africa, and how these effects differ between colonial powers and regions. The study combines a historic perspective combined with an empirical analysis of bilateral trade flows between France, the United Kingdom, and their former colonies over the
A dedicated sample of Large Hadron Collider proton-proton collision data at centre-of-mass energy s = 8 TeV is used to study inclusive single diffractive dissociation, pp → X p. The intact final-state proton is reconstructed in the ATLAS ALFA forward spectrometer, while charged particles from the dissociated system X are measured in the central detector components. The fiducial range of the measur
