Silver and palladium help unveil the nature of a second r-process

Context. The rapid neutron-capture process, which created about half of the heaviest elements in the solar system, is believed to have been unique. Many recent studies have shown that this uniqueness is not true for the formation of lighter elements, in particular those in the atomic number range 38 < Z < 48. Among these, palladium (Pd) and especially silver (Ag) are expected to be key indicators

Influence of Viscosity Ratio on the Mixing Process in a Static Mixer: Numerical Study

The mixing process in a Lightnin Series 45 static mixer, 40 mm in diameter, has been investigated using computational fluid dynamics and the volume of fluid (VOF) method, a method developed for immiscible fluids but here used for miscible. The mixing process was investigated for two liquids that had viscosities ranging from 0.003 to 51.2 Pa s, and the volumetric flow rate proportion between the li

Neurodegenerative Biomarkers in Healthy Elderly - with special reference to the preclinical pattern of biological and cognitive markers for Alzheimer’s disease

Background: Alzheimer’s disease (AD) is a neurodegenerative disorder characterized by tau and amyloid brain pathology. With the gradual degeneration of neurons, cognitive symptoms will arise and the affected individual will eventually develop AD dementia. The neuropathologic hallmarks of AD have been observed also in cognitively healthy individuals, which has led to the assumption that the disorde

Genetic variation in GIPR influences the glucose and insulin responses to an oral glucose challenge

Glucose levels 2 h after an oral glucose challenge are a clinical measure of glucose tolerance used in the diagnosis of type 2 diabetes. We report a meta-analysis of nine genome-wide association studies (n = 15,234 nondiabetic individuals) and a follow-up of 29 independent loci (n = 6,958-30,620). We identify variants at the GIPR locus associated with 2- h glucose level (rs10423928, beta (s.e.m.)

Resistivity Modelling of Fracture Zones and Horizontal Layers in Bedrock

2D resistivity modelling was done in order to examine the imaging resolution of 4 different configurations for mapping of fracture zones in bedrock. The studied arrays include Dipole-dipole, Gradient, Pole-dipole and Wenner. A variety of geological models were tested and the imaging possibilities and limitations of the different arrays were analysed. Apart from imaging fracture zones with various

Attosecond control of electron-ion recollision in high harmonic generation

We show that high harmonic generation driven by an intense near-infrared (IR) laser can be temporally controlled when an attosecond pulse train (APT) is used to ionize the generation medium, thereby replacing tunnel ionization as the first step in the well-known three-step model. New harmonics are formed when the ionization occurs at a well-defined time within the optical cycle of the IR field. Th

Evaluation of hand bone loss by digital X-ray radiogrammetry as a complement to clinical and radiographic assessment in early rheumatoid arthritis: results from the SWEFOT trial

Background: To investigate hand bone loss (HBL) measured by digital X-ray radiogrammetry (DXR) in patients with early rheumatoid arthritis (RA) receiving different treatment regimens, and to evaluate if DXR change rates during the first 12 months correlate with radiological damage after 24 months. Methods: From the total SWEFOT trial population, 159 patients had hand radiographs correctly timed an

Using EMG for Real-time Prediction of Joint Angles to Control a Prosthetic Hand Equipped with a Sensory Feedback System

All commercially available upper limb prosthesis controllers only allow the hand to be commanded in an open and close fashion without any sensory feedback to the user. Here the evaluation of a multi-degree of freedom hand controlled using a real-time EMG pattern recognition algorithm and incorporating a sensory feedback system is reported. The hand prosthesis, called SmartHand, was controlled in r

Editorial: Film Workshops in Europe

Abstract in Undetermined The editorial introduces the special issue on film workshops, situating the workshops as minor cinemas, and discussing the revised historiography of film.

Reduced Receivers for Faster-than-Nyquist Signaling and General Linear Channels

Popular Abstract in Swedish Dagens samhälle är allt mer beroende av elektroniska hjälpmedel så som smarta telefoner, läsplattor, datorer osv. Prestandakraven ökar i en allt högre takt och därför måste även den bakomliggande teknologin följa samma trend. De flesta av oss vill att den nya mobiltelefonen ska ha så hög kameraupplösning som möjligt men få av oss tänker på att detta medför en större mäFast and reliable data transmission together with high bandwidth efficiency are important design aspects in a modern digital communication system. Many different approaches exist but in this thesis bandwidth efficiency is obtained by increasing the data transmission rate with the faster-than-Nyquist (FTN) framework while keeping a fixed power spectral density (PSD). In FTN consecutive information

Magnetic and Magneto-Transport Characterization of (Ga,Mn)(Bi,As) Epitaxial Layers

High-quality layers of the (Ga,Mn)(Bi,As) quaternary compound semiconductor have been grown by the low-temperature molecular-beam epitaxy technique. An effect of Si incorporation into the (Ga,Mn)As ferromagnetic semiconductor and the post-growth annealing treatment of the layers have been investigated through examination of their magnetic and magneto-transport properties. Significant enhancement o

The construction and controlling effect of a moral brand

This paper explores the control effect of a moral brand through its brand culture. The moral brand culture distinguishes itself from other brand cultures by drawing on external claims for legitimacy. In this case, the brand drew upon a strong brand community, moral narratives in society, and the participative engagement with its values by many employees. As a consequence of these multiple and ofte

Relationship Between Ljungan Virus Antibodies, HLA-DQ8, and Insulin Autoantibodies in Newly Diagnosed Type 1 Diabetes Children

Environmental factors, including viral infections, may explain an increasing and fluctuating incidence of childhood type 1 diabetes (T1D). Ljungan virus (LV) isolated from bank voles have been implicated, but it is unclear whether LV contributes to islet autoimmunity, progression to clinical onset, or both, of T1D. The aim was to test whether LV antibodies (LVAb) were related to HLA-DQ and islet a

The interconnected KIT receptor and Microphthalmia-associated transcription factor axis in melanoma

Popular Abstract in Swedish Den farligaste formen av hudcancer, melanom, uppkommer genom okontrollerad tillväxt av melanocyter som är celler specialiserade i pigmentproduktion. Dessa celler skyddar oss från den farliga UV-strålingen med hjälp av pigment som omvandlar ljusvågor till värme. I Sverige drabbas drygt 2000 personer per år av sjukdomen. Cirka 80-85 % av dessa botas genom kirurgi men hos Melanoma is an aggressive disease that arises from deregulated signaling events in melanocytes. The KIT receptor tyrosine kinase and the Microphthalmia-associated transcription factor (MITF) are two essential components that are required for the normal physiology of melanocyte development and function. Consequently, aberrant activities of these factors are involved in the development of melanoma.
