Strain and phase evolution in TiAlN coatings during high-speed metal cutting : An in operando high-energy x-ray diffraction study

We report on phase and strain changes in Ti1-xAlxN (0 ≤ x ≤ 0.61) coatings on cutting tools during turning recorded in operando by high-energy x-ray diffractometry. Orthogonal cutting of AISI 4140 steel was performed with cutting speeds of 360–370 m/min. Four positions along the tool rake face were investigated as a function of time in cut. Formation of γ-Fe in the chip reveals that the temperatur

#MeToo Activism as Pragmatic Justice Seeking

As #MeToo activists took their testimonies of sexual harm outside the legal arena to seek justice, the #MeToo movement has commonly been framed as pitting informal justice-seeking against formal law. This article draws on interviews with Swedish #MeToo activists and focuses on their experiences of justice seeking. It asks the key question: what does justice look like for #MeToo participants? I dem

Attitudes, Barriers, and Concerns Regarding Telemedicine Among Swedish Primary Care Physicians : A Qualitative Study

PURPOSE: The primary care physician's traditional patient contacts are challenged by the rapidly accelerating digital transformation. In a quantitative survey analysis based on the theory of planned behavior, we found high behavioral intention to use telemedicine among Swedish primary care physicians, but low reported use. The aim of this study was to further examine the physicians' experiences re

Societal costs of illegal drug use in Sweden

Background: Illegal drug use is a public health concern with far-reaching consequences for people who use them and for society. In Sweden, the reported use of illegal drugs has been growing and the number of drug-induced deaths is among the highest in Europe. The aim of this study was to provide a comprehensive and up-to-date estimation of the societal costs of illegal drug use in Sweden, relying

A systematic review of ventilation solutions for hospital wards : Addressing cross-infection and patient safety

Despite various preventive interventions, nosocomial cross-infection remains a significant challenge in healthcare facilities worldwide. Consequently, prolonged hospitalization, elevated healthcare costs, and mortality rates are major concerns. Proper ventilation has been identified as one of the possible interventions for reducing the risk of cross-infection between patients and healthcare worker

On shrinking targets and self-returning points

We consider the set Rio of points returning infinitely many times to a sequence of shrinking targets around themselves. Under additional assumptions we improve Boshernitzan’s pioneering result on the speed of recurrence. In the case of the doubling map as well as for some linear maps on the d-dimensional torus, we even obtain a dichotomy condition for Rio to have measure-zero or one. Moreover, we

The ratio of total cholesterol to high density lipoprotein cholesterol and myocardial infarction in Women's health in the Lund area (WHILA) : a 17-year follow-up cohort study

BACKGROUND: Identifying variables predictive of acute myocardial infarction (AMI) in women is important. The use of the ratio of total cholesterol-to-high density lipoprotein cholesterol (TC/HDL-C) is often overlooked. The aim was to study TC/HDL-C in relation to later AMI, in a large sample of women, adjusted for age, educational status, smoking, waist-hip ratio, blood pressure, and neighbourhood

The anthropogenic imprint on temperate and boreal forest demography and carbon turnover

Aim: The sweeping transformation of the biosphere by humans over the last millennia leaves only limited windows into its natural state. Much of the forests that dominated temperate and southern boreal regions have been lost and those that remain typically bear a strong imprint of forestry activities and past land-use change, which have changed forest age structure and composition. Here, we ask how

Cardiovascular disease risk in early rheumatoid arthritis : the impact of cartilage oligomeric matrix protein (COMP) and disease activity

Background: To investigate whether baseline serum cartilage oligomeric matrix protein (COMP), patient characteristics, traditional cardiovascular disease (CVD) risk factors and disease activity over time predict CVD, in early rheumatoid arthritis (RA). Methods: This study included patients with early RA (< 12 months disease duration) (n = 233) recruited 1995–2005. Potential predictors of CVD and c

The Institutional Fragmentation of Global Environmental Governance

One of the core institutional phenomena and challenges in today’s international relations is a growing degree of fragmentation. Ongoing regulation and legalization processes have led to material and functional overlaps between international institutions. As a consequence, “problems of fragmentation arising from the segmentation of governance systems along sectoral lines” have become unavoidable.In

Effects of Hypothermia vs Normothermia on Societal Participation and Cognitive Function at 6 Months in Survivors After Out-of-Hospital Cardiac Arrest: A Predefined Analysis of the TTM2 Randomized Clinical Trial

Importance The Targeted Hypothermia vs Targeted Normothermia After Out-of-Hospital Cardiac Arrest (TTM2) trial reported no difference in mortality or poor functional outcome at 6 months after out-of-hospital cardiac arrest (OHCA). This predefined exploratory analysis provides more detailed estimation of brain dysfunction for the comparison of the 2 intervention regimens.Objectives To investigate t

The effect of valve design on the pressure losses in a high-pressure homogenizer : An improved pressure drop correlation for estimating gap height

Understanding how the design of high-pressure homogenizer valves influence pressure losses in the device is of general interest for performance optimizing, and of special importance for developing correlations for predicting gap heights and gap velocities. The traditionally used correlation is from 1975 and based on a limited experimental dataset on gaps that are longer and often of lower capacity

Modified Neumann-Neumann methods for semi- and quasilinear elliptic equations

The Neumann--Neumann method is a commonly employed domain decomposition method for linear elliptic equations. However, the method exhibits slow convergence when applied to semilinear equations and does not seem to converge at all for certain quasilinear equations. We therefore propose two modified Neumann--Neumann methods that have better convergence properties and require less computations. We pr
