Context. Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky. The precision, accuracy, and homogeneity of both astrometry and photometry are unprecedented. Aims. We highlight the power of the Gaia DR2 in studying many fine structures of the Hertzsprung-Russell diagram (HRD). Gaia allows us to present many different HRDs,
Introduction: To remain competitive, industrial organisations are continually faced with the challenges to improve product quality, reduce product development time, reduce production costs and lead-times. Increasingly, these challenges cannot be effectively met by isolated changes to specific organizational units. The Supply Chainis a revolutionary concept embedded in a traditional guise. In b
Purpose/Objective(s): Over 30% of advanced prostate cancers harbor a predominance of neuroendocrine prostate cancer (NEPC) differentiation. Fluorodeoxyglucose (FDG) positron emission tomography (PET) has numerous limitations in prostate adenocarcinoma (PCa-adeno), however there is no data that exists outside of isolated single person case reports to assess the utility of PET to restage and monitor
Importance: Osteoarthritis is a prevalent, debilitating, and costly chronic disease for which recommended first-line treatment is underused.Objective: To compare the effect of an internet-based treatment for knee osteoarthritis vs routine self-management (ie, usual care).Design, Setting, and Participants: This randomized clinical trial was conducted from October 2018 to March 2020. Participants in
Background: Tuberous sclerosis (TSC) is a rare genetic disorder associated with a high prevalence of drug-resistant epilepsy (DRE), for which epilepsy surgery may be a viable therapeutic option. National prospective studies with long-term follow-up (LTFU) and the identification of outcome predictors are needed.Methods: Individuals with TSC but no history of previous epilepsy surgery were identifie
PURPOSE: To analyse the risk of rhegmatogenous retinal detachment (RRD) after cataract surgery, and to identify possible risk factors.METHOD: Observational cohort study of patients undergoing cataract surgery in Region Skåne, southern Sweden, during 2015-2017 were retrieved from the Swedish National Cataract Register. These were then cross-referenced with cases of retinal detachment surgery perfor
Context. Observations of the Galactic bulge suggest that the disk formed through secular evolution rather than gas dissipation and/or mergers, as previously believed. This would imply very similar chemistry in the disk and bulge. Some elements, such as the α-elements, are well studied in the bulge, but others like the neutron-capture elements are much less well explored. Stellar mass and metallici
Smoke from western North American wildfires reached the stratosphere in large amounts in August 2017. Limb-oriented satellite-based sensors are commonly used for studies of wildfire aerosol injected into the stratosphere (OMPS-LP (Ozone Mapping and Profiler Suite Limb Profiler) and SAGE III/ISS (Stratospheric Aerosol and Gas Experiment III on the International Space Station)). We find that these m
This thesis deals with two types of problems occurring in inventory theory; pooling of stock and perishable items. All three papers in this thesis consider inventory distribution systems with continuous review. In Paper I we consider a single-echelon inventory system with two identical locations. Demands are generated by stationary and independent Poisson processes. In this paper, we allow later
According to medieval canon law, a marriage could be declared invalid if the consent had been given through force or fear. This ruling was a natural consequence of the insistence on free consent as the only requirement for a valid marriage. It did, however, entail a number of both practical and theoretical problems. It could be difficult to prove force and fear within the family, but also to defin
Water resources are fundamental to life, ecosystems, and human development. In an era of climate change and increasing water scarcity, effective management of these resources is crucial, particularly in cold regions where glaciers and snow play vital roles in hydrological cycles. Understanding and accurately modelling these complex systems is essential for sustainable water resource management, cl
Introduction: A large body of research has established a consensus that racial discrimination in CV screening occurs and persists. Nevertheless, we still know very little about how recruiters look at the CV and how this is connected to the discriminatory patterns. This article examines the way recruiters view and select CVs and how they reason about their CV selection choices, as a first step in u
Popular Abstract in Swedish Summary in Swedish Populärvetenskaplig sammanfattning Neuroblastom uppstår ur omogna nervceller i binjurarna eller i nervvävnaden bredvid ryggraden och är den vanligaste extrakraniala solida tumörformen hos barn. Varje år drabbas ca 10-15 barn i Sverige och sjukdomen uppkommer vanligast hos barn under 4 år. Trots enorma framgångar med behandlingsformer, så som cytostatAbstract Neuroblastoma is a highly malignant neoplasm found in children. Although children with high-risk neuroblastoma respond to chemotherapy, relapses are common and an estimated long-time survival prognosis is approximately 15%. Thus, there is a tremendous need for new chemotherapeutic drugs for the treatment for neuroblastoma. Polyamines are needed for cell proliferation and cell survival. Th
OBJECTIVES: Infections with extended spectrum beta-lactamase (ESBL) producing Enterobacteriaceae (EPE) are a major healthcare concern. Our goal was to investigate whether a probiotic mixture could be used for eradication therapy in patients with prolonged intestinal EPE carriage.METHODS: We performed a randomized, placebo-controlled single blinded clinical superiority trial in the south of Sweden
Iterative decoding methods allow efficient decoding of long codes that are composed of smaller component codes. As a result reliable communication can be achieved with low decoding complexity even for rates close to Shannon capacity. This makes iteratively decodable codes a very attractive object of study in modern coding theory. This thesis focuses on different kinds of cycles which appear in th
BACKGROUND: HAART has improved the survival of HIV infected patients. However, compared to patients in high-income countries, patients in resource-poor countries have higher mortality rates. Our objective was to identify independent risk factors for death in Ethiopian patients treated with HAART.METHODS: In a district hospital in Ethiopia, we treated adult HIV infected patients with HAART based on
Introduction: The first-line evidence-based treatment for chronic pain is multidisciplinary treatment involving pain-focused CBT. Studies have shown that changes in psychological flexibility (PF) during pain-focused CBT positively mediatesoutcomes, even when the treatment does not specifically target PF. While CBT and PF-based treatments for chronic pain yield small to moderate, but clinically mea
This thesis is trying to identify and give solutions for the problems occurring in polyurethane sport surfaces in Iraq where the climate is extremely warm and dusty. One of the most important problems (called the ‘maintenance’ problem) is that the polyurethane sport surface looks very dirty because of the dust, a couple of weeks after installation of the surface the dust particles penetrates the s
Why studying proteins is important All our cells contain hereditary information, DNA, that allows the building blocks of our body, the cells, to know how to behave. However, the DNA is only the instruction book while proteins are the key players doing all the important work. We have to cope with many situations throughout our lives, such as stress, hunger and sickness among various others, and it
Background: It has been estimated that approximately 20% of all Swedish children grow up with parents having alcohol problems, which may result in negative outcomes among these children. Therefore, most Swedish municipalities provide resources for support, but at the same time figures reveal that not even 2% receive support, mainly due to difficulties in identifying and recruiting these children i
