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 significance of load modeling for voltage stability studies has been emphasized by several disturbances, which have taken place in the past years. They have shown that the loads in combination with other dynamics are among the main contributors of prolonged low voltage conditions, voltage instability and collapse in the power system. As a result of these disturbances new investigations have co
BACKGROUND: The aim of this study was to explore changes in mobility in terms of ambulation and transfer over 1 year in patients with early-onset Alzheimer's disease (EOAD), and to compare mobility in EOAD with patients with other types of early-onset dementia (EOOD). METHOD: Forty-two patients with EOAD and 30 patients with EOOD were included. All patients were home-dwelling and had mild or moder
The coastline of Hai Hau District, located on the northeast coast of Vietnam with about 30 km of shoreline, is chronically eroding. Previous studies have tried to highlight the main causes of the erosion along this coastline, and several hypotheses exist. To examine the hypothesis that gradients in the longshore sediment transport rate and cross-shore fine sediment lost offshore are the main cause
Popular Abstract in Swedish Populärvetenskaplig sammanfattning: Det genomgående temat i avhandlingen är hur handeln mellan den Europeiska Unionen (EU) och utvecklingsländer kan öka. Två olika policyalternativ utvärderas: så kallade handelspreferenser samt förenklingar av handelsprocedurer. Handelspreferenser innebär i sin enklaste form att höginkomstländer kräver lägre tullar på importvaror somThe main theme of the thesis is how to increase trade between the European Union (EU) and developing countries. Two available policy options are assessed: trade preferences and trade facilitation. Chapter 1 offers a broad discussion of these policies, and concludes that while trade preferences, which once dominated North-South trade relations, are at a risk of becoming obsolete, trade facilitation
In order to produce drinking water, coagulants - such as aluminium salts - are widely used for precipitation and separation of impurities from raw water. The residual from the process is sludge, which presents a disposal problem. The REAL process is a method for recycling the aluminium from the sludge. In a first step, the aluminium hydroxide is dissolved in sulphuric acid. In a second step, an ul
1. During operative aorto-femoral vascular reconstructions on sixteen patients, the sympathetic chain was stimulated electrically between the L2 and L4 ganglia while blood flow was monitored by laser doppler flowmeters from the skin on the sole of the foot and the ankle and by an electromagnetic flowmeter from the deep femoral artery. Epidural anaesthesia to at least the T6 level was used which ex
A laser diagnostic concept for measurement of potassium chloride (KCl) and potentially other alkali compounds in large-scale boilers and furnaces of limited optical access is presented. Single-ended, range-resolved, quantitative detection of KCl is achieved by differential absorption light detection and ranging (DIAL) based on picosecond laser pulses. Picosecond DIAL results have been compared exp
BACKGROUND AND PURPOSE: Surgical treatment of chronic acromioclavicular joint dislocations is challenging, and no single procedure can be considered to be the gold standard. In 2010, the GraftRope method (Arthrex Inc., Naples, FL) was introduced in a case series of 10 patients, showing good clinical results and no complications. We wanted to evaluate the GraftRope method in a prospective consecuti
A measurement of the production cross section for two isolated photons in proton-proton collisions at a center-of-mass energy of s=8 TeV is presented. The results are based on an integrated luminosity of 20.2 fb-1 recorded by the ATLAS detector at the Large Hadron Collider. The measurement considers photons with pseudorapidities satisfying |ηγ|40 GeV and ET,2γ>30 GeV for the two leading photons or
Background: Chronic pain is common in older adults, yet little is known of its development in old age. Although fear-avoidance beliefs in chronic pain have been explored in younger adults, the relationship between chronic pain, kinesiophobia and physical activity levels has not been investigated in older adults.Objectives: The overall aim was to explore prevalence, development and related factors
Addressing sustainability concerns in supply chain operations can be a matter of long-term business survival for food retailers. However, regardless of whether it is perceived as a risk or market opportunity, acting across the value chain to address unsustainable production and consumption practices has been a constant challenge. This thesis investigated the sustainable supply chain management (SS

The 1976 premiere of Face to Face came at the height of director-screenwriter Ingmar Bergman's career. Prestigious awards and critical acclaim had made him into a leading name in European art cinema, yet today Face to Face is a largely overlooked and dismissed work.This book tells the story of its rise and fall. It presents a new portrait of Bergman as a political artist exploring a new medium wit
The neurochemical profile of the cortex develops in a region and time specific manner, which can be distorted by psychiatric and other neurological pathologies. Pre-clinical studies often involve experimental mouse models. In this study, we determined the neurochemical profile of C57BL/6 mice in a longitudinal study design to provide a reference frame for the normal developing mouse cortex. Using
Meteorites have captured our fascination since our early history-they have evoked awe, fear, an irresistible curiosity, and numerous lively debates. Former historians have indicated that many of the ancient cultures and civilizations in Europe, Africa, Asia, the Inuit, and the native Indians in America regarded both the meteorite and the location of their fall as sacred. Thus, they used the meteor
Chemical hypersensitivity is an immunological response towards foreign substances, commonly referred to as sensitizers, which gives rise primarily to the clinical symptoms known as allergic contact dermatitis. For the purpose of mitigating risks associated with consumer products, chemicals are screened for sensitizing effects. Historically, such predictive screenings have been performed using anim
