Lignin depolymerisation can be utilized to produce value-added aromatic compounds. One of the major challenges in lignin depolymerisation study is the development of effective analytical tools to unravel the huge complexity of the depolymerisation product mixture.

Crude oil is the most traded energy commodity in the world, and its price has a large impact on the everyday life of billions. Given the volatility of crude oil prices and its enormous effects on economies worldwide, there has been a growing demand for risk quantification and risk management for the market participants. The measurement known as Value-at-Risk (VaR) has become the industry standard
This diploma work is made for the Faculty of Engineering (LTH) at Lunds University and for the HVAC consultant company Helenius ingenjörsbyrå. The objectives were to find ways of determining what size of ventilation systems that are required for biological research and ways of lowering energy consumption focused on ventilation in laboratories, without lowering the safety for workers and environme
Popular Abstract in English Experiments, such as the Large Hadron Collider (LHC) in CERN, Switzerland, collide particles together at high energies, in the hope of probing the fundamental constituents and forces of nature. On the theoretical side, the Standard Model (SM) is currently the best description we have. It is a theory that encompasses the strong, weak and electromagnetic forces, although This thesis involves phenomenological models for describing high energy particle collisions. One class of these models, multiparton interactions (MPI), deals with the fact that when colliding two hadrons, it is possible for more than one pair of their constituents to interact. The other deals with parton showers, which are used to fill enhanced regions of phase space and give fully exclusive final
Business opportunities are a chance for a company to grow its activity and to further the aggregate welfare of the society as a whole. Corporate opportunities rules and their functional equivalents should enable companies to develop their business activities when directors discover those business opportunities. Companies need to be certain that they can legally appropriate those business opportuniBusiness opportunities are a chance for a company to grow its activity and to further the aggregate welfare of the society as a whole.

Susceptibility Weighted Imaging is an MRI- and post-processing technique that utilize the phase information from the MR signal to enhance the contrast in areas with different susceptibility than surrounding tissue in T2*-weighted images. This technique is becoming more and more important as a clinical tool. Susceptibility-weighted imaging has been commercialized by Siemens Healthcare under the acr
This work will first go through different definitions about what constitute a holding company. Thereafter the Swedish tax rules, relevant for the localisation of a holding company, will be examined. Subsequently different definitions will be discussed about what constitute a holding company. In that context the concept tax paradise will be discussed. In the next chapter those criterias will be dis
The construction sector is responsible for around 40 % of all generated waste in Sweden and is also responsible for around 21-22 % of all carbon emissions. In a sector that is responsible for a substantial part of Sweden’s climate footprint, it’s important to find solutions to the negative effects towards the climate. Much of the generated waste comes from building and demolition waste which ends
A major challenge for a person with diabetes is to adapt insulin dosage regimens and food intake to keep blood glucose within tolerable limits during daily life activities. The early knowledge about the effects of inputs on glycemia would provide the patients with invaluable information for appropriate on-the-spot decision making concerning the management of the disease. Against this background, i
Flower colour is an important signal used by flowering plants to attract pollinators. Many anthophilous insects have an innate colour preference that is displayed during their first foraging bouts and which could help them locate their first nectar reward. Nevertheless, learning capabilities allow insects to switch their colour preferences with experience and thus, to track variation in floral nec
Background: In a microarray experiment the difference in expression between genes on the same slide is up to 103 fold or more. At low expression, even a small error in the estimate will have great influence on the final test and reference ratios. In addition to the true spot intensity the scanned signal consists of different kinds of noise referred to as background. In order to assess the true spo
Denna avhandling utforskar relationen mellan politik och nya medier genom en studie av digital diplomati i den Europeiska utrikestjänsten (EEAS) 2011-2017. Den belyser hur en diplomatisk organisation internaliserar medielogik. Traditionella ansatser utgår ofta från att medielogiken tar över den politiska logiken. I denna avhandling betonas istället betydelsen av politisk kontext, dess aktörer och This thesis explores the relationship between politics and new media in the context of digital diplomacy at the European External Action Service (EEAS) 2011-2017. In contrast to dominant approaches to the mediatization of politics that consider political logic to be dominated or even replaced by media logic, it gives greater emphasis to the role of the political context, its actors and their pract
BackgroundDespite the fact that eldercare services are organizationally part of social work in Sweden, the social work practice is disappearing and older people are expected to take the responsibility for their own well-being. In this context, they have to create their own sense of meaningfulness in their everyday life, despite being subject to social care services.Methods As part of a research prBackgroundDespite the fact that eldercare services are organizationally part of social work in Sweden, the social work practice is disappearing and older people are expected to take the responsibility for their own well-being.

Methods: Drug-induced interstitial lung disease (ILD) is crucial to detect early to achieve the best treatment outcome. Optimally, non-invasive imaging biomarkers can be used for early detection of disease progression and treatment follow-up. Therefore, reliable in vivo models are warranted in new imaging biomarker development to accelerate better-targeted treatment options. Single-dose bleomycin

Objectives: Pain is the most common and troublesome complaint in rheumatoid arthritis (RA). This study aimed to assess the prevalence and clinical implications of unacceptable pain in an inception cohort of patients with RA. Method: This study followed 477 patients from the BARFOT (Better Anti-Rheumatic FarmacOTherapy) early RA cohort for 15 years. Unacceptable pain was defined as ≥ 40 mm on a vis
