Reliable methods for estimating financial return volatility are crucial in many areas of trading and investing. Two such frameworks, the GARCH and SV, have been of particular interest to academics and practitioners alike. The GARCH model describes the variance of the current innovation as a function of the actual sizes of the previous innovations. In contrast, the stochastic volatility model descr
As a relatively new form of financial asset with unique properties, Bitcoin is increasingly included in portfolios to improve performance. However, research remains limited on how Bitcoin actually affects portfolio performance. This study aimed to broaden the field of research by exploring whether Bitcoin can improve portfolio performance during a global crisis. It sought to answer the question by
A dye-binding method using Acid Orange 12 was investigated regarding its suitability for the quantification of available lysine, as a means of monitoring the Maillard reaction in skim milk powders. The method was evaluated by analyzing a wide range of milk powders produced by three different drying methods and stored under various conditions. A pilot-scale freeze-dryer, spray-dryer and drum-dryer
Sammanfattning Sedan den första november 2008 har metoden för framställning av muntlig bevisning i hovrätt ändrats. Med anledning av reformen ”En modernare rättegång” moderniserades rättegången i hovrätten. Moderniseringen innebar bland annat att ljud- och bildupptagning som gjorts i tingsrätten, i regel spelas upp som muntlig bevisning i hovrätten. Nu finns förslag på att den delen av hovrättsförSummary Since November 1st 2008, the method of presenting oral testimonies in the Swedish Court of Appeal has changed. Since the reform “More modern court proceedings” the trials in Court of Appeal have become modernized. The modernization meant, inter alia, that audiovisual recording that have been conducted at the Swedish District Courts are, as a rule, played at the Court of Appeal. The recordi
A measurement of elastic deeply virtual Compton scattering gamma*p --> gamma p using e(+) p and e(-) p collision data recorded with the HI detector at HERA is presented. The analysed data sample corresponds to an integrated luminosity of 306 pb(-1), almost equally shared between both beam charges. The cross section is measured as a function of the virtuality Q(2) of the exchanged photon and the ce
Direct ozone (O-3) injection is a promising flue-gas treatment technology based on oxidation of NO and Hg into soluble species like NO2, NO3, N2O5, oxidized mercury, etc. These product gases are then effectively removed from the flue gases with the wet flue gas desulfurization system for SO2. The kinetics and mixing behaviors of the oxidation process are important phenomena in development of pract
In this paper the design and demonstration of a 7 nm(3) h(-1) integrated steam reforming based hydrogen production unit using a Fischer-Tropsch diesel is reported. The system design is discussed in detail, including the fuel processor itself as well as the hydrogen purification and results from stand-alone operation of the combined unit operations is reported. Further, the results of an integratio
We present a high-resolution and independently dated multiproxy lake sediment record from the paleolake at Les Echets in southeastern France that displays synchronous changes in independent limnic and terrestrial ecosystem proxies, in concert with millennial-scale climate oscillations during the last glacial period. Distinct lake-level fluctuations, low lake organic productivity, and open, treeles
Biomass derived gases produced via gasification, pyrolysis, and fermentation are carbon neutral alternative fuels that can be used in gas turbines, furnaces, and piston engines. To make use of these environmentally friendly but energy density low fuels the combustion characteristics of these fuels have to be fully understood. In this study the structure and laminar burning velocity of biomass deri
Objective: The aim of this study was to analyse the occurrence of neonatal early onset group B streptococcal (EOGBS) disease relative to maternal body mass index (BMI). Method: A cohort of Swedish parturients with an early pregnancy BMI registered was investigated. Data were retrieved from population-based registers during 1997-2001, (n = 344 127, elective caesarean section excluded). Medical reco
The reduction of the (A root 5x root 5)R27 degrees surface oxide on Pd(100) and Pd75Ag25(100) surfaces by CO has been investigated by high-resolution X-ray photoelectron spectroscopy in combination with kinetic analysis using the Avrami-Erofeev theory. For both surfaces we observed faster reduction with increasing temperature. Kinetic analysis indicates that the reduction process is phase boundary
Accelerated pavement wear is one of the major environmental disadvantages of studded tyres in northern regions and results in increased levels of PM10. Measurements of PM10 in a road simulator hall have been used to study the influence of pavement properties, tyre type and vehicle speed on pavement wear. The test set-up included three different pavements (one granite and two quartzite with differe
The purpose of the present study was to examine the potential effectiveness of a group cognitive-behavioral therapy (CBT) for adults with attention-deficit hyperactivity disorder (ADHD) with residual significant clinical symptoms after being stabilized on medication. All adult patients with ADHD in an outpatient psychiatric clinic who had been stabilized on medication but still showed clinical sig
Syftet med uppsatsen är att undersöka hur familjevåld påverkar bedömningen av barnets bästa i frågor om vårdnad, boende och umgänge. Med våld avses våld riktat mot någon annan i familjen än barnet. Jag har använt mig av tre frågeställningar för att lyfta fram vilken betydelse våldet har för barnet. Den första frågeställningen är mer övergripande och handlar om hur våldet påverkar barnets bästa. DeThe aim of this thesis is to examine how domestic violence affects the decision of what is in the best interest of the child with regards to parental authority judgments. In this thesis the term domestic violence refers to all violence towards another family member except the child himself. The thesis is built upon three questions in order to highlight the impact domestic violence has upon the dec
Abdominal trauma occurring in persons older than 60 years over a 30-year period (1950-79) in a well defined region of Sweden was reviewed. The 177 patients comprised 12.5% of the total with abdominal trauma during that period. Road traffic accidents were the main cause of trauma (48% of cases). The incidence of motor-car accidents rose sharply during the first two decades of the study. Injuries to
In the year of 2004, a tsunami struck the coast of Thailand. Around 30 000 Swedish tourist was present, and over 500 was killed. The Swedish government acted slowly in helping its citizens, which created a political crisis in Sweden when the support for the government declined. After the crisis management of the tsunami was over, the government started to reform Sweden’s national security. The mai
The main concerns associated with epilepsy during pregnancy consist of maternal and fetal risks from uncontrolled seizures, and harmful effects of the treatment on the development of the offspring. Although seizure control is maintained in the majority, worsening occurs in a fraction of childbearing women with epilepsy. As multiple factors associated with pregnancy may have a negative impact on ep
Youth represent a great part of humanity and have always been active and intriguing political actors, yet youth remain sidelined in international studies. Issues of social identity perception and its consequences have been embraced by post-positivist approaches in international studies. Yet, while race, gender, and class challenges are shaking the discipline, age is a key research gap. To fill thi
Purpose: To evaluate inter- and intrarater reliability, of the Eating and Drinking Ability Classification System (EDACS) for children and adults with cerebral palsy (CP) in Sweden. Methods: Four speech and language pathologists rated EDACS from videos of 30 individuals with CP, 3 to 62 years, (mean 21 y, 10 m, SD 18 y, 6 m), six at each level of the Gross Motor Function Classification System (GMFC
