Mechanisms that govern transport, accumulation and toxicity of persistent pollutants at interfaces in aquatic ecosystems are the foci of this thesis. Specific attention is paid to humic substances, their occurrence, composition, and role in exchange processes across interfaces. It was concluded that: Composition of humic substances in aquatic surface microlayers is different from that of the subsu
A recurrent issue and to a considerable extent also a major obstacle in contemporary theology of religions are various claims of "uniqueness". This article critically considers one particular aspect, i.e., the quest of the unique Jesus in New Testament scholarship and its implications for global interreligious dialogue. It is argued that the quest of the unique Jesus be abandoned since it is neith
This paper presents results for vehicle-to-vehicle channel characterization based on measurements conducted for the merging lane scenarios on a highway. We present power delay profiles as well as channel gains and analyze important propagation mechanisms to see the impact of line-of-sight (LOS) and the antenna radiation pattern on the total received power. It is found that the absence of LOS and s
This paper presents the characterization of forced cooling channels with three different shapes which are applied in traction motors mounted in Hybrid Vehicles (HEVs) or Zero Emission Vehicles (ZEVs). Generally, there are two different positions of forced cooling channels in electric motors. One way is by drilling holes or cutting cooling channels inside the housing, which is called indirect cooli
Det finns två huvudsakliga svar på frågan varför forskning och utveckling, F&U, i området digitala läromedel är viktig. Det första är relativt uppenbart: Det produceras idag allt fler digitala läromedel som används i ökad utsträckning i skolan. För att kunna ta fram digitala läromedel av hög kvalitet krävs forskning och utveckling. Det andra och mindre uppenbara svaret är att digitala läromede
We present a method for the estimation of the distribution of the quasi-static hogging-bending moment for a floating body. Starting points of this study are temporal characteristics of the sea state. The approximation is deduced from the estimation of the joint distribution of crest amplitude and crest length. The quality of the model is investigated by comparing computed distributions with empiri
There are water vapour condensation and two-phase flow in plate heat exchangers when they are used as condensers. Water phase change and flow dynamics modelling is an important but complicated task due to large change in water physical/transport properties across the water liquid-vapour interface boundary. In particular, singular-link behaviour in governing equations is present due to the large st
Today embedded system development is a complex task. To aid the engineers new methodologies and languages are emerging. During the development the system is modeled using different tools and languages. Transformations between the models are traditionally done manually. We investigate the automation of this process, specifically we are looking at automatic UML to SystemC transformation. In this pap
This paper presents the preliminary evaluation of different powered-wheelchair control modes for individuals with severe motor impediments. To this end, a C400 Permobil wheelchair has been updated with a control command communication interface and equipped with a scanning laser sensor to carry out the automation algorithms that are part of the robot operating system framework. A pilot test was per
Availability of safe, edible food is essential. Food shortage has caused many wars and encouraged people to try to preserve food for a longer time, allowing storage and transport, often in some kind of package/container. The USA showed the way in developing the food sector and already prior to the 2nd World War they had self-service stores filled with packed goods. Europe, however, had to wait to
This paper examines information services in association with charging services, and in particular players that offer information services related to charging service offerings from many different operators. It identifies two main types of business models through studying and comparing 25 European charging information service providers. For one type of players the paper analyses the network charact
Objectives: To analyse and present regression models that can describe the long-term change in cognitive function (MMSE and ADAS-cog) of patients treated with donepezil for three years (n=435). Methods: The Swedish Alzheimer Treatment Study (SATS) is an open, 3-year, multicentre study in a routine clinical setting. Patients with the diagnosis of Alzheimer’s Diseases received the cholinesterase inh
The diagnosis of Alzheimer's disease can be improved by the use of biological measures. Biomarkers of functional impairment, neuronal loss, and protein deposition that can be assessed by neuroimaging (ie, MRI and PET) or CSF analysis are increasingly being used to diagnose Alzheimer's disease in research studies and specialist clinical settings. However, the validation of the clinical usefulness o
Motivated by experimental findings on one-dimensional nano-materials, this contribution focusses on the elaboration of a fibre curvature based higher-order gradient contribution to the stored energy function in a finite deformation setting. The presented approach is based on the fundamental theoretical developments for fibre-reinforced composites presented by Spencer and Soldatos (2007), which tak
