The Øresund Fixed Link is a 15,9 km road and railway connection between the southerly Swedish city of Malmö and its neighbor across the Øresund strait, Copenhagen, in Denmark. The link, which opened in 2000, consists of an elevated bridge, including a high stay cable bridge, an artificial island, as well as a submerged tunnel. The operators of the link, Øresundsbron Consortium, have recently, as p

During their formation, nascent planetary systems are subject to FU Orionis outbursts that heat a substantial part of the disc. This causes water ice in the affected part of the disc to sublimate as the ice line moves outwards to several to tens of astronomical units. In this paper, we investigate how the subsequent cooling of the disc impacts the particle sizes. We calculate the resulting particl

Mixed species charge and baryon balance functions are computed based on proton-proton (pp) collisions simulated with the PYTHIA8 model. Simulations are performed with selected values of the collision energy s and the Monash tune and the ropes and shoving modes of PYTHIA8 to explore whether such measurements provide useful new information and constraints on mechanisms of particle production in pp c

Background: Endoscopic resection of T1 colon cancer (CC) is currently limited by guidelines related to risk of lymph node metastases. However, clinical outcome following endoscopic and surgical resection is poorly investigated. Method: A retrospective multicentre national cohort study was conducted on prospectively collected data from the Swedish colorectal cancer registry on all non-pedunculated

Limiting the global production of primary plastics is necessary to curb greenhouse gas emissions as well as the environmental and health impacts ofplastic pollution.A cap on primary plastic production is possible and has precedent in environmental and climate change law. One approach for implementing such a cap is through a cap-and-trade system, which involves the distribution of production allowa

Background: Infants in the neonatal intensive care unit (NICU) are subjected to different types of stress, including sounds of high intensity. The sound levels in NICUs often exceed the maximum acceptable level recommended by the American Academy of Pediatrics, which is 45 decibels (dB). Hearing impairment is diagnosed in 2% to 10% of preterm infants compared to only 0.1% of the general paediatric

Standardmodellen inom partikelfysik har besvarat många av de frågor som människan har ställt genom åren. Till exempel har vi fått svar på frågor som: Vad är de minsta partiklarna uppbyggda av? Vilka krafter får dem att röra sig som de gör? Hur får partiklar sin massa? Även om många frågor har fått svar, leder varje öppnad dörr till en ny dörr bakom, med ett nytt lås vars nyckel ännu inte har hittaIn this thesis, we study the Higgs boson mass spectrum of a Scale Invariant Two Higgs Doublet Model that includes an additional real singlet. This model results in three neutral CP-even states due to the mixing with the singlet. At tree level, one of these states has zero mass. To obtain a consistent and accurate mass spectrum for the Higgs bosons, the scale invariance is broken by incorporating r

As climate change continues leads to rising global temperatures and poses the threat of extreme weather conditions, the cooling energy demand within the building sector is experiencing rapid growth. This study aims to compare both energy performance and cost efficiency between all-air cooling systems and water-based cooling systems by investigating variable air volume (VAV) system and ceiling radi

Vad gör egentligen en plats inbjudande och inkluderande för alla? När känner sig folk hemma på en plats och vad krävs för att ett offentligt rum ska kännas som sitt andra vardagsrum? Det är frågor jag funderat kring och undersökt i mitt kandidatarbete.

This thesis examines the nature and purpose of the Greek sciences ἀριθμητική, λογιστική and γεωμετρία in the texts of Plato. The statements of some other ancient authors are also mentioned, and the relevant modern research is consulted. ἀριθμός is at any instance, as Klein has already noted, ‘a definite number of definite objects’. In Plato’s philosophical ἀριθμητική, ἀριθμός seems to always consi

Ecological genomics approaches have informed us about the structure of genetic diversity in natural populations that might underlie patterns in trait variation. However, we still know surprisingly little about the mechanisms that permit organisms to adapt to variable environmental conditions. The salt marsh foundation plant Spartina alterniflora exhibits a dramatic range in phenotype that is assoc

We developed a panel of 44 nuclear genetic markers and applied this to two hybridizing species of marbled newts in the north (Triturus marmoratus) and the south (Triturus pygmaeus) of the Iberian Peninsula, to investigate pattern and process of interspecific gene flow. The northernmost occurrence of T. pygmaeus genetic material was in a T. marmoratus population north of the Vouga river estuary. Th

Mitt val av ämne grundar sig i min egen relation till stress och nervositet. Jag har alltid känt att jag haft svårt att hantera stress och att det begränsat mig i mina prestationer. Det pratas mycket om mental träning, men jag har inte vetat hur jag ska börja. Därför har jag valt att basera detta arbete på ett färdigt koncept. Det finns i Don Greenes bok ”Audition Success” och är en övning som hanMy choice of subject is based on my own relationship with stress and nervousness. I have always felt it difficult to handle stress and that it has limited my performances. People talk about nervousness a lot, but I have not known where to start. Therefore, my investigation is based on an already existing method. It is to be found in Don Greene’s book “Audition Success” and is an exercise about cen

The three species of banded newt (genus Ommatotriton) are endemic to the Near East. Recently an introduced banded newt population was discovered in Catalonia, Spain. To determine the species involved and the geographical source, we genotyped 11 individuals for one mitochondrial and two nuclear genetic markers, and compared the observed haplotypes to a range-wide phylogeography of Ommatotriton. All

Secondary contact between closely related species can lead to the formation of hybrid zones, allowing for interspecific gene flow. Hybrid zone movement can take place if one of the species possesses a competitive advantage over the other, ultimately resulting in species replacement. Such hybrid zone displacement is predicted to leave a genomic footprint across the landscape in the form of asymmetr

"Storsjöodjuret”, eller “The Great Lake Monster”, är ett undflyende fenomen i sjön Storsjön, belägen i landskapet Jämtland i norra Sverige. Denna avhandling i ämnet humanekologi undersöker hur det sammankopplingar av det sociala, det kulturella, det historiska och det lokala påverkar formandet av detta svenska kryptid, eller “dolda djur”. Syftet med studien är att visa hur detta vetenskapligt ännuStorsjöodjuret, or The Great Lake Monster, is an elusive phenomenon in lake Storsjön, situated in the province of Jämtland in Northern Sweden. This dissertation in Human Ecology investigates how the intricate web of the social, the cultural, the historical, and the local influence the shaping of this Swedish cryptid, or “hidden animal”. The purpose of the study is to demonstrate how this scientifi

Peptide mass fingerprinting of bone collagen (ZooMS) has previously been proposed as a method to calculate the extent of the non-enzymatic degradation of glutamine into glutamic acid (deamidation). Temporal and spatial variation of glutamine deamidation at a single site, however, has not been investigated. Here we apply ZooMS screening of Châtelperronian and Early Holocene bone specimens from Quin

The banded newt (genus Ommatotriton) is widely distributed in the Near East (Anatolia, Caucasus and the Levant) – an understudied region from the perspective of phylogeography. The genus is polytypic, but the number of species included and the phylogenetic relationships between them are not settled. We sequenced two mitochondrial and two nuclear DNA markers throughout the range of Ommatotriton. Fo
