In the truck industry there is a continuous demand to increase the efficiency and to decrease the emissions. To acknowledge both these issues a waste heat recovery system (WHR) is combined with a partially premixed combustion (PPC) engine to deliver an efficient engine system. Over the past decades numerous attempts to increase the thermal efficiency of the diesel engine has been made. One such at

Objective To investigate if the prediction of malignant adnexal masses can be improved by considering different ultrasound-based subgroups of tumors and constructing a scoring system for each subgroup instead of using a risk estimation model applicable to all tumors. Methods We used a multicenter database of 1573 patients with at least one persistent adnexal mass. The masses were categorized into

Dimers of A beta (amyloid beta-protein) are believed to play an important role in Alzheimer's disease. In the absence of sufficient brain-derived dimers, we studied one of the only possible dimers that could be produced in vivo, [A beta](DiY) (dityrosine cross-linked A beta). For comparison, we used the A beta monomer and a design dimer cross-linked by replacement of Ser(26) with cystine [A beta S

Patients with coeliac disease living on a gluten-free diet show vitamin deficiency and reduced subjective health status. To study the biochemical and clinical effects of B vitamin supplementation in adults with longstanding coeliac disease. In a double blind placebo controlled multicentre trial, 65 coeliac patients (61% women) aged 45-64 years on a strict gluten-free diet for several years were ra

Many attempts have been made to catch the essence of Joseph Conrad’s work by examining the contents of his ideas. This thesis argues instead that the important factor is the preferred spatial structures of his world-views and the interplay between them. Above all, Conrad’s work can be seen as a battle-ground between closing and opening structures. The former have a claustrophobic effect on the con

Colour is disregarded in the analysis of the grammar of a building façade. Contemporary architecture, as well as traditional historical architecture, is built on a relation between colours. Colour schemes of vernacular architecture is a part of the local regional heritage.A re-established exterior colour scheme in rural areas would strengthen the local identity. In Sweden the dominating part of ve

This paper deals with the design of channel estimators in the uplink of an OFDM based multi-user system. First, we propose a user allocation scheme that is based on the aim to use the correlation of the radio channel for channel estimation purposes. Further, we present the linear MMSE channel estimator based on a few pilot tones. We present an error analysis that proves valuable in the evaluation

This paper addresses the decline in infant mortality that occurred with a remarkable synchronization across Europe around the turn of the century 1900. It is the argument of this paper that this development is not just, as in the conventional view, the side effect of economic growth but could be derived through a cumulative chain of events, starting with the discovery of the germ theory. Mokyr has

Background. When delivering an embedded product, such as a mobile phone, third party products, like games, are often bundled with it in the form of Java MIDlets. To verify the compatibility be- tween the runtime platform and the MIDlet is a labour-intensive task, if input data should be manually generated for thousands of MIDlets. Aim. In order to make the verification more efficient, we investiga

This paper intends to offer an overview of current knowledge in practical moisture safety in wood frame house. Books, journal articles, reports and other documents at different levels regarding moisture and moisture safety in different aspects are summarized. Possible gaps and flaws in existing knowledge, such as, lack of blind verifications of moisture safety calculation tools, the need to separa

Computer-based design analysis is nowadays a common activity in most development projects. Used for design evaluation, verification, validation, or as a support for design exploration, it fulfils an important support function for the engineering designer, thus making it essential to have an operationally efficient and effective integration between both the engineering design and design analysis ac

The Evaporative Gas Turbine Pilot Plant has been in operation at Lund Institute of Technology in Sweden since 1997. In this cycle low-grade heat in the flue gases is utilized for water evaporation into the compressed air in the humidification tower. This result in, amongst others, power augmentation, efficiency increase and lower emissions. This article presents the experimental and theoretical re
