Lignin depolymerisation receives great attention due to the pressing need to find sustainable alternatives to fossil sources for production of fuels and chemicals. In this study, alumina-supported Cu–Mn and Ni–Mo catalysts were tested for oxidative depolymerisation of a technical lignin stream—sodium lignosulphonates—to produce valuable low-
A hybrid catalyst consisting of Zr-doped mesoporous silica (Zr-SBA-15) supports with intergrown Cu nanoparticles was used to study the effects of a catalyst’s chemical states on CO2 hydrogenation. The chemical state of the catalyst was altered by using tetraethyl orthosilicate (TEOS) or sodium metasilicate (SMS) as the silica precursor in the synthesis of the Zr-SBA-15 framework, and infiltration A hybrid catalyst consisting of Zr-doped mesoporous silica (Zr-SBA-15) supports with intergrown Cu nanoparticles was used to study the effects of a catalyst’s chemical states on CO2 hydrogenation.

Under den tidigmoderna och förindustriella perioden arbetade en stor del av den unga, ogifta allmogebefolkningen i Sverige som tjänstefolk, som drängar och pigor i andras hushåll. Där var de legalt underordnade husbonden och matmodern enligt särskilda tjänstehjonsstadgor och de hade begränsade möjligheter att söka annan försörjning, samtidigt som de ofta delade arbete och vardag med husbondfolket.The aim of this thesis is to analyze the power relations of labour and gender in the servant institution during the agrarian revolution in Sweden. The positions of servant, master and mistress are analyzed theoretically as a gendered, contracted position with both economic and moral dimensions attached to them. The analysis is applied together with a theory on bases of power, which are those areas
The advantage of using nonlamellar lipid liquid crystalline phases has been demonstrated in many applications, such as drug delivery, protein encapsulation and crystallisation. We have recently reported that a mixture of mono- and diglycerides is able to form sponge-like nanoparticles (L
Objective: To study the association between country of birth and incident dementia in several immigrant groups in Sweden. Methods: The study population included all adults (n = 3,286,624) aged 45 years and older in Sweden. Dementia was defined as having at least one registered diagnosis of dementia in the National Patient Register. The incidence of dementia in different immigrant groups, using Swe
When utilising archaeomagnetic data to constrain geomagnetic field models, uncertainties in inclination are often given as the angular standard deviation. This is a factor of √2 larger than the standard deviation of the marginal distribution of inclination and a number of recent studies have overestimated the sampling contribution to the error budget. More generally, the uncertainties in inclinati
We demonstrate the enhancement of femtosecond (fs) laser-induced filaments in air and nitrogen flow fields using a nanosecond (ns) laser. With the ns laser being imposed on the filaments, the length and the emission intensity of the filaments were largely increased. Temporally resolved spectra of the enhanced filaments were obtained. The re
Numerous recent studies project that ‘climate engineering’ technologies might need to play a major role in the future. Such technologies may carry major risks for developing countries that are often especially vulnerable to, and lack adaptive capacity to deal with, the impacts of such new technologies. In this situation, one would expect that developing countries—especially the least developed cou
In internal cooling passages in a turbine blade, rib structures are widely applied to augment convective heat transfer by the coolant passing through over the ribbed surfaces. This study concentrates on perforated 90 deg ribs with inclined holes in a cooling duct with rectangular cross section, aiming at improving the perforated holes with additional secondary flows caused by inclined hole arrange
Dynamic global vegetation models are a common tool to assess the effect of climate and land use change on vegetation. Though most applications of dynamic global vegetation models use plant functional types, some also simulate species occurrences. While the current development aims to include more processes, e.g. the nitrogen cycle, the models still typically assume an ample seed supply allowing al
Using NMR and Monte Carlo (MC) methods, we investigate the stability and dynamics of superoxide dismutase 1 (SOD1) in homogeneous crowding environments, where either bovine pancreatic trypsin inhibitor (BPTI) or the B1 domain of streptococcal protein G (PGB1) serves as a crowding agent. By NMR, we show that both crowders, and especially BPTI, cause a drastic loss in the overall stability of SOD1 i
We study the boundary behavior of functions in the Hardy spaces on the infinite-dimensional polydisc. These spaces are intimately related to the Hardy spaces of Dirichlet series. We exhibit several Fatou and Marcinkiewicz- Zygmund type theorems for radial convergence of functions with Fourier spectrum supported on N0∞∪(−N0∞). As a consequen
Studies on survival between familial and sporadic cancers have been inconclusive and only recent data on a limited number of cancers are available on the concordance of survival between family members. In this review, we address these questions by evaluating the published and unpublished data from the nation-wide Swedish Family-Cancer Database and a total of 13 cancer sites were assessed. Using sp
The aim of the present study was to investigate psychodynamic psychotherapists’ experience of the influence of personal therapy on professional growth during training with a focus on the acquisition of knowledge and the development of psychotherapeutic skills. Thematic analysis was conducted on interviews with former students (N=10) at two training institutes for psychoanalytic psychotherapy. The
In this paper, we consider a mobile platform with two cameras directed towards the floor. In earlier work, this specific problem geometry has been considered under the assumption that the cameras have been mounted at the same height. This paper extends the previous work by removing the height constraint, as it is hard to realize in real-life applications. We develop a method based on an equivalent
During a metal cutting process, chemical wear can become the dominant mechanism of tool degradation under the high temperatures and contact pressures that arise between the tool and the metal workpiece. This study focuses on the chemical and diffusional interactions between superalloy Inconel 718 and cubic boron nitride (cBN) tool material with and without TiC binder. It covers thermodynamic model
Background: Twenty percent of the patients with AAA have an aneurysm involving the common iliac arteries. Large common iliac diameter can be treated with an iliac branched device or extension of the stent graft to the external iliac artery with occlusion of the ipsilateral internal iliac artery (IIA) to prevent type 2 endoleaks. This study describes and evaluates a embolization technique using Ony
