Popular Abstract in Swedish Med dagens alla transporter finns det ett mycket stort behov av tillgång till billigt och miljövänligt drivmedel. Det bränsle som används i särklass mest är bensin framställd från råolja. Ett problem med bensinen är att den inte tillverkas från förnyelsebara råvarukällor. Detta innebär att när oljan tar slut så går det inte att tillverka mer bensin. Däremot är det idag In order to produce fuel ethanol from lignocellulose, it is necessary to hydrolyse the sugar-containing constituents hemicellulose and cellulose. During acid hydrolysis, a number of compounds are formed or liberated in addition to the fermentable monomeric sugars. Several of these compounds might act as inhibitors during the fermentation of the sugars to ethanol. Thus, in order to obtain high etha

During recent years we have seen several large-scale crises. The 9/11 terror attacks, tsunamis, storms, floods and bombings have all caused a great deal of damage. A common factor in these crises has been the need for information and one important source of information is usually Web sites. In this work we investigate and design an overload control system for Web sites that are vital in crises. Th

In very-large multiple-input multiple-output (MIMO) systems, the BS (base station) is equipped with very large number of antennas as compared to previously considered systems. There are various advantages of increasing the number of antennas, and some schemes would require handling large matrices for joint processing (pre-coding) at the base station. The dirty paper coding (DPC) is an optimal pre-

The innovation process is a challenge for companies trying to achieve better outcomes through new ideas or products. The related literature discusses the importance of innovation as a learning process, underlined by a design perspective. Supported by design, the innovation process combines multidisciplinary aspects of creativity and dynamism, mainly for end-user oriented industries. For other indu

A highly optimized Monte Carlo (MC) code package for simulating light transport is developed on the latest graphics processing unit (GPU) built for general-purpose computing from NVIDIA - the Fermi GPU. In biomedical optics, the MC method is the gold standard approach for simulating light transport in biological tissue, both due to its accuracy and its flexibility in modelling realistic, heterogen

Summary of key messages for policy makers • Systemic approach is critical Climate change and natural resource depletion continues to be driven not least by unsustainable levels and patterns of consumption. There is growing recognition that the shift required to achieve sustainable consumption and production is a momentous paradigm shift in Western culture. Due to the holistic nature of shifting c

Antibody-based microarrays have emerged as an established proteomic technology allowing multiplexed and sensitive profiling of complex proteomes, in a high-throughput and miniaturized manner. Recently, numerous applicative efforts have been pursued generating disease-associated protein signatures that now could be further explored for improved disease diagnostics, prognostics and classification.

This report is produced within the Urban Transition Øresund (UT) project (2011–2014), and it is part of the subtask Collaborative Methods and Tools for Urban Transitions (UT CoMeT). The goal of the UT project is to promote sustainable growth and advance sustainable urban transformation in the Øresund region by gathering municipalities, universities and businesses in cross-border cooperation. The s

The main objectives with this investigation are firstly to compare important parameters of a capacitive micromachined ultrasonic transducer (cMUT) for air applications with a corresponding piezoelectric ultrasonic transducer. Secondly, to characterise the cMUT's radiation field using light diffraction tomography. The cMUTs consist of a silicon backplate with small pyramid-shaped cavities and a met

Human antibodies generated in vitro may be highly valuable for diagnostic and therapeutic purposes. For a long time most human antibodies produced in vitro have been of the IgM isotype with rather low affinities. In this thesis a method for production of IgG switched antigen-specific human antibodies is presented. This is a two step protocol, in which the first step is a selection procedure of don

Popular Abstract in Swedish Förebyggande av hjärtkärlsjukdom har varit en utmaning för medicinsk forskning under flera decennier. Viktiga frågeställningar om såväl screeningmetodik som risk-faktor intervention söker fortfarande sitt svar och har i sig betydelse för både samhällsmedicin och klinisk verksamhet. Målsättningen för denna studie var att undersöka möjligheten för läkare och sjuksköterskoCardiovascular disease prevention has been a challenge for research for decades. The studies of this thesis were designed to investigate the role of health professionals in everyday clinical work based upon the concept of comprehensive primary care consultation. Routine check-up of blood pressure was the basis for the inclusion in an opportunistic screening for hyperchol-esterolaemia. Additionally

We deal with a natural integer-linear programming formulation of the routing and spectrum allocation (RSA) problem in elastic optical networks. We focus on strengthening the formulation with valid inequalities (cuts). For this purpose we apply clique inequalities that proved to be useful in other applications of this kind. We develop and combine a clique cut generation procedure with a column gene

Popular Abstract in Swedish Cancer i tjock- och ändtarmen är idag den tredje vanligaste formen av till döden ledande cancer i världen. Den är vanligast i de högindustrialise-rade delarna av världen: Europa, Nord-Amerika och Australien. Prognosen för den enskilde patienten är helt beroende på cancerns utbredning vid diagnostillfället. Cancerns utbredning bedöms idag enligt olika indelningsprincipeAim of the study Today´s methods for the staging of rectal carcinoma: ultrasonography with transrectal probe, CT, MRI or MRI with a rectal coil, all have limitations. The aim was therefore to develop a new, double-contrast MRI method for evaluation of rectal carcinoma. The idea was that a rectally applied contrast medium causing distension and signal void of the rectal lumen and an intravenous inj
