3D-models of bone structures from computed tomography (CT) data can be used for surgical planning, education and a wide range of other purposes. They can also be used in both digital and 3D-printed format. The currently used process to obtain such models consists of a combination of thresholding, morphological operations and manual adjustments. This can be very time-consuming. Deep Learning (DL) c

Hud, hår och naglar är utåt sätt olika, men på en mikroskopisk nivå är likheterna stora. Det översta lagret av hud, som kallas stratum corneum, hår och naglar består av döda celler till mestadels fyllda av proteinet keratin. Keratinet i dessa celler bildar cylindriska strukturer; keratinfilament, som består av flera keratinkedjor. Denna uppbyggnad ger materialen både styrka och flexibilitet. LipidThe keratin structure and mobility of protein and lipid components in keratinous materials, and the changes in these properties upon hydration and addition of osmolytes affects the mechanical properties and permeation of skin, hair and nails. In this thesis, the effect of hydration and the addition of solvents and an osmolyte on the structure of keratin filaments and on the mobility of protein an

Vid en fastighetstransaktion har säljaren enligt JB 4:19 ett abstrakt felansvar. Detta felansvar infördes när den nya jordabalken trädde i kraft år 1972. Innan dess hade säljaren inte detta abstrakta felansvar, utan endast ett ansvar för sådant som denne gjort direkta utfästelser om. Förändringen medförde därför en förskjutning av risken att behöva stå för ett fel från köparen till säljaren. Ett sIn a real estate transaction, according to chapter 4, paragraph 19, in the Swedish Land Code, the seller has an abstract liability. This liability was introduced when the new Land Code came into force in 1972. Prior to that, the seller did not have this abstract liability, but only a responsibility for things that he made direct commitments to. The change therefore led to a shift in the risk of ha

Rapid urbanisation coupled with unplanned development create the perfect recipe for a disaster, the risk of which has increased with climate change-related uncertainties. Belgrade’s high population growth rate and exposure to riverine flooding presents such a case. This study aims to provide insight into the relationship between urban development and riverine flooding in Belgrade and thereby induc

Evidence is indicating that human activity within the Anthropocene, the proposed geological epoch of the current time, are causing extraction of natural resources and land, terraforming, climate change and mass extinction of species (Anthropocene: The Human Epoch, 2018). The identified environmental pressure will continue to grow as the global population is expected to reach 11 billion before the

The society has gone from production equipment being the most valued asset in the organizations, to today, having the human asset and their competencies as a valuable and critical contributor to business profit. Competency Management has, therefore, received much attention and been a common Human Resource practice in the past decades. However, it is still an unexplored process in many private and

This work analyzed the impact caused by different intensities of Pulsed Electric Fields (PEF) pre-treatment on the biogas production from small-scale anaerobic digesters of wastewater sludge under thermophilic conditions. PEF technology consists of passing the substrate through an electric field which generates a potential difference across the cells, resulting in electroporation. Mixed sludge fro

Detta examensarbete undersöker möjligheterna att implementera magneter för flera funktioner i en så kallad ”knob”. Projektet utfördes i samarbete med Sigma Connectivity.

Biofilmer finns på ytor överallt runtomkring oss: på våra tänder (plack), på våta ytor i t ex. badrummet och på stenar i vattendrag. Biofilmer är ytterst tunna (vanligtvis mindre än 1 mm) och består av aggregat av mikroorganismer, såsom bakterier, vilka omges av en skyddande hinna. Dessa aggregat bildar ett ”supersamhälle” av mikroorganismer som gör det möjligt för dem att lättare samarbeta med vaThe anaerobic moving bed biofilm reactor (AnMBBR) is a wastewater treatment process that has shown effective for the treatment of industrial wastewaters. As the AnMBBR is a biofilm process, nutrients, products, etc. must be transported through the biofilm. The thickness of the biofilm may, therefore, impact the process. The objectives of this study were (1) to evaluate the effect of the biofilm th

Aktivitet hos humlor och fjärilar Vad är egentligen aktivitet? Tänk på det som om när du funderar på att gå och handla. Du vill inte handla när alla andra gör det för då kommer det vara stor konkurrens när du väl ska betala i kassan. Samtidigt vill du inte komma försent till affärerna och riskera att varan du ska handla tagit slut. Så frågar är: När är den optimala tiden att handla? Lite på samBiodiversity of bumblebee and butterfly species in the agricultural landscape are declining and conservation actions are needed. Conservation measures have the potential to be more effective if they are conducted at the right time. Previous studies have investigated the patterns of activity of bumblebees and butterflies. However, they have failed to look at differences in activity depending on spe

Konsten att släktforska på en 1mm stor vattenloppa En vattenloppa är ett litet plankton som vanligtvis lever i sjöar, men ett fåtal bor i den marina miljön. En speciell vattenloppa, Penilia avirostris, kommer ursprungligen från varmare områden runt ekvatorn, men har sedan 1990 observerats i Nordsjön och därefter (2003) påträffats i Öresund. Men hur kan en liten vattenloppa, som lever i varmare vaPenilia avirostris is a marine Cladoceran species typically occurring in tropical and subtropical regions. Several studies have revealed a global expansion of the species and an invasion of the North Sea since 1990. By analysing the phylogeny of the species, it could be possible to unveil its origin and direction of expansion. This molecular method has been applied for Cladoceran systematics with

The purpose of this study was to investigate whether consumer behavior in grocery stores could be affected through nudging by rearranging the product placement and putting up suggestive messages to customers. It also investigated whether nudging is more effective when targeting short-term versus long-term consequences of consumer behavior, as their abstract levels are processed differently. It spe
