The occurrence rate of close-in super-Earths is higher around M-dwarfs compared to stars of higher masses. In this work, we aim to understand how the super-Earth population is affected by the stellar mass, the size of the protoplanetary disc, and viscous heating. We utilised a standard protoplanetary disc model with both irradiated and viscous heating, together with a pebble accretion model, to si
BACKGROUND: Studies in patients with peripheral arterial disease (PAD) have reported an association between inflammatory markers and severity of disease or worsening of symptoms. However, few have studied the prognostic significance of inflammatory markers in asymptomatic subjects, measured many years before the onset of symptomatic PAD requiring treatment (trPAD).MATERIAL AND METHODS: Five inflam
Heparan sulphate and chondroitin/dermatan sulphate proteoglycans of human skin fibroblasts were isolated and separated after metabolic labelling for 48 h with 35SO4(2-) and/or [3H]leucine. The proteoglycans were obtained from the culture medium, from a detergent extract of the cells and from the remaining 'matrix', and purified by using density-gradient centrifugation, gel and ion-exchange chromat
OBJECTIVE: to analyse the impact of stent-graft (SG) design and operator skill on the outcome of endovascular AAA repair. DESIGN: prospective non-randomised open. MATERIAL: a total of 158 patients (mean age 71) underwent SG repair. Patients were treated with five different types of SG: first (n =58) and second ( n =17) generation Ivancev-Malmo monoiliac SG (IM I and IM II respectively) combined wi
Exercise during adolescence, especially during the pre-pubertal years, builds a skeleton with a high bone mineral density (BMD) and possibly a larger skeleton with a different skeletal architecture. This would lead to a stronger skeleton more resistant to trauma. These changes could be of biological significance for fracture reduction, if they were maintained into old age where fragility fractures
Second-generation bioethanol produced from various lignocellulosic materials, such as wood, agricultural or forest residues, has the potential to be a valuable substitute for, or a complement to, gasoline. One of the crucial steps in the ethanol production is the hydrolysis of the hemicellulose and cellulose to monomer sugars. The most promising method for hydrolysis of cellulose to glucose is by
The influence of the auxotrophic deficiencies of the host strain and expression vector selection on the production of a heterologous protein was investigated. Heterologous xylanase production by two prototrophic S. cerevisiae transformants, containing either a plasmid-based, YEp-type expression system or an integrative, YIp-type expression system, were compared with production by an auxotrophic tr
Transposition of intestinal segments is frequently used for bladder reconstruction. Following transposition, bowel segments continue to produce mucus and a correlation between excessive mucus production and complications such as urinary tract infection or catheter blockage has been observed for a long time. However, no information is currently available on the change of mucin expression and glycos

In Sweden, beef production is the most greenhouse gas intensive sector of meat production. When it comes to biodiversity in Sweden, pastures and meadows are greatly contributing to this as they among the most species rich habitats in the country. On the other hand, pastures and meadows are becoming afforested due to decreased grazing. Hence, the purpose of this paper was to examine how land use in
Ease of Doing Business Index is published every year by the World Bank, and is used to describe how simple it is to start-up and run a business in different parts of the world. The index is constructed by eleven indicators, which are based upon around forty underlying variables. This essay examines the correlation between the underlying variables for the indicators Starting a business and Paying
CERN operates the most complex particle accelerator facility built until today. As such, it consists of thousands of custom-made components spread both in upper ground facilities and in underground tunnels and caverns. Several different hazards, including fire, are present in these facilities and need to be reduced to a tolerable level; in particular, fire safety often requires the application of
During the last few years, the interest for electric vehicles has increased enormously, there are even talk of prohibiting fossil fuels in the coming years. There is a risk that the charging of these electric vehicles can strain the electric grid. The simulations of the grid with added power demand from the electric vehicles concludes that there will not be a problem on the low- and medium voltage
In this bachelor project, the electron transport within quantum dot transistor devices, whose barriers are electrostatically induced, was measured and analysed. The properties of devices with this particular architecture are not yet fully understood. We successfully synthesised several 150x50x50 nm of these devices, where the potential barrier gates are defined next to the nanowire to form the qua
Barns rättigheter har konsekvent missbrukats under väpnade konflikter. Det har skett mer än 266 000 allvarliga kränkningar av barns rättigheter mellan 2005 och 2020, även om det verkliga antalet förmodligen är högre. FN har identifierat sex allvarliga kränkningar av barns rättigheter vid väpnade konflik-ter. Avhandlingen syftar till att belysa hur upprättelse för kränkningar av de sex allvarliga k
Forskningsfrågor: Är det statistiskt signifikant att det finns en förändringar i aktieavkastning på optionens förfallodag i den underliggande aktien? har de öppna options kontrakten en påverkan på aktieavkastningen på optionens förfallodag? Syfte: Syftet med examensarbetet är att undersöka om det finns en signifikant skillnad i aktieavkastningen vid optionens förfallodag i relation till de öppna Research questions: Is there significant change in the stock return on option expiration dates in the underlying stock? Does the net open interest have an effect on the return of the underlying stock on option expiration day?
