Recent and exciting in vivo studies show that supplementation with the polyamine spermidine (Spd) is cardioprotective and prolongs lifespan in both mice and humans. The mechanisms behind Spd-induced cardioprotection are supposed to involve Spd-evoked stimulation of autophagy, mitophagy and mitochondrial respiration and improved the mechano-elastical function of cardiomyocytes. Although cellular up
To improve the overall heat transfer of supercritical carbon dioxide (SCO 2 ) in a horizontal circular tube, this study proposes a novel kind of tube with cylindrically concaves and fillets on the circular surface. Several tubes
Congenital thrombocytopenic purpura (TTP) is a rare but serious condition. We present a case of a 29-year-old woman, diagnosed with this disease in adulthood. The episode that led to diagnosis was triggered by quetiapine. She presented with neurological symptoms and laboratory findings including low platelets and elevated creatinine. Interestingly, the signs of hemolysis were very subtle. Her symp
The objective was to design a thin, flex card based personal dosemeter with low angular and energy dependence. It is based on silicon diodes that can measure the personal dose equivalent. Anisotropic conducting adhesive was used to connect the Si sensor to the flex card. Its intended use is for interventional radiology and after nuclear or radiological accidents, as it provides immediate detailed
Massively parallel sequencing holds great promise for new possibilities in the field of forensic genetics, enabling simultaneous analysis of multiple markers as well as offering enhanced short tandem repeat allele resolution. A challenge in forensic DNA analysis is that the samples often contain low amounts of DNA in a background that may interfere with downstream analysis. PCR inhibition mechanis
BackgroundLignin is a potential feedstock for microbial conversion into various chemicals. However, the microbial degradation rate of native or technical lignin is low, and chemical depolymerization is needed to obtain reasonable conversion rates. In the current study, nine bacterial strains belonging to the Pseudomonas and Rhodococcus genera were evaluated for their ability to grow on alkaline-tr
This article compares the opportunities that existed for trade union organisation by women and the scope for pursuing women’s issues in the Swedish Tailoring Workers’ Union (Skrädderiarbetareförbundet), the Swedish Textile Workers’ Union (Textilarbetareförbundet) and the Swedish Women’s Trade Union (Kvinnornas fackförbund). Trade union minutes are analysed using theories on women’s organisation, i
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
