At Norje Sunnansund, an Early Holocene settlement in southern Sweden, the world’s earliest evidence of fermentation has been interpreted as a method of managing long-term and large-scale food surplus. While an advanced fishery is suggested by the number of recovered fish bones, until now it has not been possible to identify the origin of the fish, or whether and how their seasonal migration was ex

Background: Tumour-infiltrating lymphocytes (TILs) are of important prognostic and predictive value in human epidermal growth factor receptor 2-positive (HER2+) breast cancer (BC) and triple-negative breast cancer (TNBC), but their clinical relevance in oestrogen receptor-positive/HER2-negative (ER+/HER2−) remains unknown. The primary study aim was to analyse the prognostic effect of TILs on the B

Purpose: To describe the rationale and design of the VOYAGER (NCT05476926) study, which aims to investigate the safety and effectiveness of faricimab and the Port Delivery System with ranibizumab (PDS) for neovascular age-related macular degeneration (nAMD) or diabetic macular edema (DME) in clinical practice. VOYAGER also aims to understand drivers of clinical practice treatment outcomes by gaini

Quality enhancement projects in universities frequently rely on short-term, fragmented studies implemented in response to snapshot data linked to student feedback. Such projects may not address the complex interplay across stakeholder groups and do not always acknowledge the unintended consequences of change. This article, focused on systems design, draws on research conducted over seventeen years

Understanding the molecular details of bioenergetic processes is fundamentally important. Defects in the mitochondrial energy metabolism can lead to untimely apoptosis and thus cause serious degenerative human diseases. Other defects in mitochondrial energy metabolism can have the reverse effect and cause cell immortality and also contribute to and high metastatic potential of tumor cells. Knowi

Omni-channel retailing, the concept of offering consumers a seamless experience by integrating physical stores and online channels, is growing within the retail industry. This transformation has forced entire organizations to rethink their logistics network and fulfillment operations, which has resulted in an endeavor to work more cross-functionally in businesses. This shift makes the competence r

Purpose: The aim of this study is to explore and understand how online music consumers develop loyalty towards musicians as brands, along with potential reasons behind that process. Methodology: The study explores the phenomenon of loyalty development of online music consumers towards musicians as brands. The exploratory, relativist and abductive perspectives have been adopted through a series of

The study asks what role Karl Marx’s theory of the law of the tendency of the rate of profit to fall has in explaining transformation, crises and secular stagnation in Sweden. Support is presented for the “law”, with Sweden exhibiting a long-term secular decline in the rate of profit throughout the late 19th and 20th century. For the period 1950-2016, there is a strong tendency towards “Marx-biase

Accidents always get a lot of public attention. Journalists appear at the site of an accident, taking pictures and making interviews with professionals and eyewitnesses. With the emergence of smartphones, online-media, and social media platforms such as Twitter, Facebook, Instagram, etc. everyone became a journalist. It is no longer only accidents catching public attention but also near misses, sm

I detta examensarbete har man undersökt hur olika renheter på vatten påverkar kvaliteten på vattenbaserade färgprodukter. Man har använt sig av två olika renade vatten och kranvatten som kontroll. De renade vatten som användes var avjoniserat vatten och destillerat vatten. Avjoniserat vatten renas genom filtrering och destillerat vatten renas genom kokning och uppsamling av vattenångan. KvaliteteIn this project the effect different water qualities had on water-based paint products were investigated. Tap water was used as a control and deionised and distilled water were used to determine whether the water purity had an impact on the quality of the finished paint products. One intermediate and five finished products were used to investigate the effect of water purity. The intermediate was

Mammalian vocalisations are extremely diverse, and evolutionary approaches to understanding this diversity assume that much of their acoustic form maps onto their function, with specific features serving universal roles. Here, we hypothesize that nonlinear phenomena (i.e., deterministic chaos, sidebands, subharmonics, and frequency jumps), which make the voice perceptually rough or harsh, contribu

Surface states and traps play an important role in the photophysics of colloidal quantum dots. These states typically lead to large red-shifted photoluminescence. We have used steady-state and time-resolved spectroscopic techniques to investigate the nature of the traps and their lifetimes in colloidal CdSe quantum dots. We conclude that at least two different types of traps contribute to the phot

OBJECTIVE: To investigate whether patients with severe radiographic osteoarthritis (OA) have a different outcome at one year after total hip replacement than patients with moderate radiographic OA. To investigate sex related differences in preoperative radiographic and self reported status and in postoperative outcome.METHODS: 184 patients (96 women) with a mean age at surgery of 71.4 years (50-92

Background: Polymorphisms in and around the CTLA-4 gene have previously been associated to TiD and AITD in several populations. One such single nucleotide polymorphism ( SNP), CT60, has been reported to affect the expression level ratio of the soluble ( sCTLA- 4) to full length CTLA- 4 ( flCTLA- 4) isoforms. The aims of our study were to replicate the association previously published by Ueda et al

This paper is the first to apply a finite mixture model to a sample of 64 nations to endogenously analyze the cross-country growth behavior over the period 1870-2003. Results show that growth patterns were segmented in two worldwide regimes, the one characterized by convergence in per capita income, and the other by divergence. Interestingly, when three historical epochs are distinctly analyzed, i

We tested whether routes of raptors migrating over areas with homogeneous topography follow constant geomagnetic courses more or less closely than constant geographical courses. We analysed the routes taken over land of 45 individual raptors tracked by satellite-based radiotelemetry: 25 peregrine falcons, Falco peregrinus, on autumn migration between North and South America, and seven honey buzzar

A photon echo experiment has been performed using accumulated highly attenuated laser pulses. We show experimentally that the photon echo process can be performed with, on the average, less than one photon in each pair of excitation pulses. The results support an interpretation where this nonlinear process can be performed with, on the average, less than one photon shared between two of the optica

Increased research is being driven by the automotive industry facing challenges, requiring to comply with both current and future emissions legislation, and to lower the fuel consumption. The reason for this legislation is to restrict the harmful pollution which every year causes 3.3 million premature deaths worldwide [1]. One factor that causes this pollution is NOx emissions. NOx emission legisl
