The quantum mechanical equivalent of the classical Hall effect can lead to interesting results in solid state physics.A similar effect, that has received attention in recent years, occurs when large spin-orbit coupling is present in a material, the so-called quantum-spin Hall effect.In two-dimensional materials it leads to so-called helical edge states that exhibit counter-propagating electron sta

Coastal eutrophication due to excessive anthropogenic nutrient loading is a major threat worldwide, and especially in estuaries and semi-enclosed waterbodies, like the brackish Baltic Sea. In addition, coastal waters may become darker (coastal darkening) due to increased input of colored compounds from terrestrial run-off and sediment resuspension. Still, the effects of darkening on coastal food w

The “heat dissipation limit” theory (HDL) posits that animals with higher capacity to dissipate metabolic heat can increase reproductive investment. This theory remains untested in the wild. We recently showed that increased workload in a small bird causally relates to maximum body temperature. Here, we have expanded this approach by experimentally facilitating sensible heat transfer rate in nestl

In order to better understand and predict the dynamics of benthic macroinvertebrate communities, we need to first define the functional components of benthic biodiversity and then provide a mechanistic description of how they interact with their abiotic environment, their basic resources and each other. These interactions should be largely controlled by readily available biological traits, making

This article aims to contribute to discussions and reflections upon the practice and theory of fire safety design. Are we reaching the results we want by the best available means? The theoretical framework of fire safety design is today restricted by a linear design process where mainly quantitative data and methods matters. A deterministic approach to safety ignores the decision-making context an

Introduction: Lactic acid bacteria (LAB) play an important role in the food industry as starter cultures to manufacture fermented food, and as probiotics. In recent years, there has been an increasing interest in using LAB cultures for biopreservation of food products. It is therefore of great interest to study the detailed metabolism of these bacteria. Objectives: This study aimed at developing a

This work investigates the performance potential of an engine running with partially premixed combustion (PPC) using commercial diesel engine hardware. The engine was a 2.01 SAAB (GM) VGT turbocharged diesel engine and three different fuels were run - RON 70 gasoline, RON 95 Gasoline and MK1 diesel. With the standard hardware an operating range for PPC from idle at 1000 rpm up to a peak load of 10

Objectives: The use of patient-reported outcome (PRO) measured outside clinical trials is not well defined. We report the first analysis of the prospective PRO study within the Swedish acute myeloid leukemia (AML) and the acute lymphoblastic leukemia (ALL) registries. Methods: PRO was requested 6 months after diagnosis. The EORTC Quality of life Questionnaire Core 30-item, the Patient Health Quest

Purpose. To investigate how individualised occupation-based interventions with commonly available everyday technology (ET) can compensate for perceived difficulties with daily life tasks after an aquired brain injury (ABI) and improve satisfaction with occupational performance. Method. This intervention study was designed as a multiple case study according to Yin. Ten men and women with an ABI (tr

An increasing number of studies describe moving hybrid zones. This raises the issue of their actual frequency and emphasizes the need for methods that enable the detection of zone movements without historical records. Asymmetric introgression, usually considered as a signature of geographical shift, might be misleading when applied to mitochondrial or potentially non-neutral markers. We investigat

Introduction: Our objective was to evaluate the association of early-pregnancy body mass index (BMI) in women with gestational diabetes mellitus (GDM) with maternal, delivery, and child outcomes, and compare with pregnancies without diabetes in southeastern Sweden, including after a surge of non-European immigration. Material and Methods: A retrospective population-based observational study of all

In modern aquaculture, animal-production technology is used to increase aquatic food sources. Such controlled rearing of seafood can, in principle, shift the pressure off wild stocks and aquatic ecosys- tems by reducing fishing activities, which may advance marine conservation goals. We examined resource displacement—the reduced consumption of a resource due to its replacement with a more environm

This doctoral thesis aims to investigate and compare conventional drying technologies (freeze-drying and spray drying) to alternative drying technologies for biologics. Vacuum foam-drying was identified as an alternative drying technology for biologics. Vacuum foam-drying is a drying technique that involves solvent removal by evaporation, at lowered pressure and ambient temperatures. Thus, vacuum

Background Bothgenetic and lifestyle factors contribute to the risk of type 2 diabetes, but the extent to which there is a synergistic effect of the 2 factors is unclear. The aim of this study was to examine the joint associations of genetic risk and diet quality with incident type 2 diabetes. Methods and findings We analyzed data from 35,759 men and women in the United States participating in the

Emerging technologies with artificial intelligence (AI) and machine learning are laying the foundation for surveillance capabilities of a magnitude never seen before. This article focuses on facial recognition, now rapidly introduced in many police authorities around the world, with expectations of enhanced security but also subject to concerns related to privacy. The article examined a recent cas

Aqueous mixtures of two non-ionic polymers, poly(acrylic acid) (PAA) and the amphiphilic triblock copolymer, (EO)27(PO)67(EO)27, known by its trade name Pluronic® P104, showed an associative phase separation (miscibility gap), which decreased with the decrease of PAA length. It was found that PAA is a much less selective “solvent” to P104 molecules than water. P104 aggregates are disintegrated and

The human genome contains a large variety of sequences related to the mouse mammary tumor virus (MMTV). We have investigated the range of expression of human endogenous retroviral sequences (HERVs) related to MMTV (human MMTV-like; HML) as RNA in 60 breast cancers, 8 nonmalignant breast tissues, and 9 placentas. This was monitored using HML group-specific oligonucleotide probes in hybridizations t

Remains of the mosasaur Clidastespropython in marine strata of latest early Campanian age from the Kristianstad Basin, southern Sweden, represent the first record of Clidastes outside of North America. The material consists of shed marginal and pterygoid tooth-crowns, and vertebrae (including eleven associated cervicals and dorsals from a juvenile). The majority of the teeth and skeletal elements
