Characterization of surface structure and oxidation/reduction behavior of Pd-Pt/Al2O3 model catalysts

Structural and morphological characterizations of bimetallic Pd-Pt/Al2O3 model catalysts are performed using X-ray diffraction, X-ray absorption spectroscopy, transmission electron microscopy, and CO chemisorption. Further, the catalysts were studied under oxidizing and reducing conditions using both X-ray absorption spectroscopy and low-energy ion scattering spectroscopy. For the as-prepared cata

Socioeconomic differences in digital inequality among Chinese older adults : Results from a nationally representative sample

The current study seeks to investigate digital inequality among older adults in China, specifically examining two socially defined age groups: young-old adults (aged 60–74) and old-old adults (aged 75+). Descriptive statistics and multiple regression were used to examine the prevalence of and identify the factors associated with Internet access, usage (frequency and breadth containing 11 activitie

Nutrient policies and the performance of aquaculture in developed countries – a literature review

Eutrophication is a serious problem in many parts of the world, and aquaculture production can contribute to the problem as well as be part of its solution. Nutrient polices in developed countries are often command-and-control policies that may have contributed to the slow growth of the sector. We perform a literature review to investigate how current nutrient polices affect the sector and if econEutrophication is a serious problem in many parts of the world, and aquaculture production can contribute to the problem as well as be part of its solution.

Potential interplay between tumor size and vitamin D receptor (VDR) polymorphisms in breast cancer prognosis : a prospective cohort study

Purpose: Vitamin D has some anticancer properties that may decrease breast cancer risk and improve prognosis. The aim was to investigate associations between four previously studied VDR SNPs (Taq1, Tru91, Bsm1, and Fok1) and prognosis in different groups of breast cancer patients. Methods: VDR genotyping of 1,017 breast cancer patients included 2002–2012 in Lund, Sweden, was performed using Oncoar

Allergic contact dermatitis due to 1,6-hexanediol diacrylate in ostomy patients

Background: Many people live with ostomies after life-saving surgery. Ostomy patients often suffer from peristomal dermatitis. Allergic contact dermatitis (ACD) has been reported, mostly due to contact allergy (CA) to topical agents. Objectives: We present three patients with therapy resistant peristomal dermatitis, suggesting ACD caused by different stoma products. Methods: Patch testing was perf

Efficiency evaluation of a conductive Electric Road System with respect to traffic characteristics

Electric Road Systems (ERS) are effective charging infrastructures that allows electric vehicles to receive energy while driving. This energy is used both to propel the vehicle and to charge the battery. Sufficient deployment of ERS implies that charging opportunities become greatly increased, allowing for electric vehicles to have smaller batteries and easing some of the problems associated with

CYCLICITY IN THE DRURY-ARVESON SPACE AND OTHER WEIGHTED BESOV SPACES

Let H be a space of analytic functions on the unit ball Bd in Cd with multiplier algebra Mult(H). A function f ∈ H is called cyclic if the set [f], the closure of {ϕf : ϕ ∈ Mult(H)}, equals H. For multipliers we also consider a weakened form of the cyclicity concept. Namely for n ∈ N0 we consider the classes Cn(H) = {ϕ ∈ Mult(H): ϕ /= 0, [ϕn] = [ϕn+1]}. Many of our results hold for N:th order radi

Simultaneous multicolour transit photometry of hot Jupiters HAT-P-19b, HAT-P-51b, HAT-P-55b, and HAT-P-65b

Accurate physical parameters of exoplanet systems are essential for further exploration of planetary internal structure, atmospheres, and formation history. We aim to use simultaneous multicolour transit photometry to improve the estimation of transit parameters, to search for transit timing variations (TTVs), and to establish which of our targets should be prioritized for follow-up transmission s

GANDER : A Platform for Exploration of Gaze-driven Assistance in Code Review

Gaze-control and gaze-assistance in software development tools have so far been explored in the setting of code editing, but other developer activities like code review could also benefit from this kind of tool support.In this paper, we present GANDER, a platform for user studies on gaze-assisted code review. As a proof of concept, we extend the platform with an assistant that highlights name rela

The predictive effect of family genetic risk scores as an indirect measure of causal effects of one disorder on another

Background One potential cause of comorbidity is the direct causal effect of one disorder - A - on risk for subsequent onset of disorder B. Could genetic risk scores be utilized to test for such an effect? If disorder A causally impacts on risk for disorder B, then genetic risk for disorder A should be lower in cases of disorder A with v. without a prior onset of B. Methods In all individuals (n =

‘They all of a sudden became new people’ : Using reproductive justice to explore narratives of hormonal contraceptive experience in Sweden

This study explores how Swedish women narrate experiences of hormonal contraceptives through utilizing the frameworks of biomedicalization and reproductive justice, adding a social justice perspective previously lacking. Ten in-depth interviews were conducted with women who had experience of using hormonal contraception. Political narrative analysis illuminated how these women moved narratively bo

The possible role of the vasopressin system in hematopoiesis

Vasopressin is a pleiotropic hormone that controls body fluid homeostasis. Vasopressin has also been proposed to be involved in erythropoiesis, thrombocyte activity and inflammation. However, whether increasing vasopressin is associated with changes in hematopoietic markers is not known. To evaluate this gap of knowledge we measured the vasopressin marker copeptin and markers of erythropoiesis (er

Comparison of histological delineations of medial temporal lobe cortices by four independent neuroanatomy laboratories

The medial temporal lobe (MTL) cortex, located adjacent to the hippocampus, is crucial for memory and prone to the accumulation of certain neuropathologies such as Alzheimer's disease neurofibrillary tau tangles. The MTL cortex is composed of several subregions which differ in their functional and cytoarchitectonic features. As neuroanatomical schools rely on different cytoarchitectonic definition

Epidemiology and clinical characteristics of biopsy-confirmed adult-onset IgA vasculitis in southern Sweden

Objective Immunoglobulin A vasculitis (IgAV) is the most prevalent primary childhood vasculitis in Sweden, but is considerably rarer in adults. This study aims to describe the epidemiology, clinical characteristics and renal outcome of adult-onset IgAV in Skåne, Sweden. Methods The study area consisted of Skåne, the southernmost region of Sweden, with a population ≥18 years of 990 464 on 31 Decemb

Smoking and home oxygen therapy : a review and consensus statement from a multidisciplinary Swedish taskforce

Background: Home oxygen therapy (HOT) improves survival in patients with hypoxaemic chronic respiratory disease. Most patients evaluated for HOT are former or active smokers. Oxygen accelerates combustion and smoking may increase the risk of burn injuries and fire hazards; therefore, it is considered a contraindication for HOT in many countries. However, there is variability in the practices and p

Optimising CH4 simulations from the LPJ-GUESS model v4.1 using an adaptive Markov chain Monte Carlo algorithm

The processes responsible for methane (CH4) emissions from boreal wetlands are complex; hence, their model representation is complicated by a large number of parameters and parameter uncertainties. The arctic-enabled dynamic global vegetation model LPJ-GUESS (Lund-Potsdam-Jena General Ecosystem Simulator) is one such model that allows quantification and understanding of the natural wetland CH4 flu
