Evaluation of the applicability of GARDskin to predict skin sensitizers in extracts from medical device materials

Biocompatibility testing of medical devices is governed by the ISO 10993 series of standards and includes evaluation of skin sensitization potential of the final product. A majority of all medical devices are tested using in vivo methods, largely due to the lack of in vitro methods validated within the applicability domain of solid materials. The GARDskin method for assessment of chemical skin sen

Dynamics of VLS-Grown Si Nanowires: Insights from Molecular Dynamics Simulations on Facet Evolution, Twinning, Nucleation, and Impurity Dynamics

A clear understanding of the mechanisms governing the growth of nanowires is crucial to achieving control over their structures and properties. Here, we employ molecular dynamics (MD) simulations to investigate several important phenomena in Au-catalyzed Si nanowires (SiNWs) grown via the vapor–liquid–solid method. MD simulation serves as a complementary tool for uncovering the mechanisms of nanow

Exploring the diversity of non-industrial private forest properties in Southern Sweden

Diverse forest landscapes contribute to reaching various forest policy goals. Understanding how the diversity of forests in a landscape is distributed among forest properties and how it is related to biogeographical and ownership factors can be helpful for effective policy implementation. We created a forest characteristics-based typology of non-industrial private forest properties aiming to captu

Speed-securing measures on rural roads in Sweden : An observational study

Objective: Speed-securing measures are intended to, as the name suggests, to secure that the speeds of road users do not exceed the safe speed for a given type of environment. The purpose of this study was to make an evaluation of existing speed-securing measures on rural roads in Sweden to see how well they manage to limit the speed. Methods and data: A total of 34 unique locations have been film

Centralisation of extremely preterm births and decreased early postnatal mortality in Sweden, 2004-2007 versus 2014-2016

Aim: We evaluated the increased centralisation of extremely preterm (EPT) births in Sweden in relation to the changes in mortality and morbidity. Methods: Population-based data covering Swedish live births from 22 + 0 to 26 + 6 weeks of gestation during 2004–2007 and 2014–2016 were analysed for associations between time-period, birth within (inborn) or outside (outborn) regional centres, and outco

The Gender Revolution: Marriage, Fertility, and Divorce in the Industrial City

This chapter focuses on industrialization and family behavior during the twentieth century against the backdrop of economic and institutional change. It documents trends regarding marriage and fertility and union dissolution from a gender perspective, and explores the role of socioeconomic status (SES) for these processes. Findings confirm patterns regarding gender and family consistent with that

Theocratically bounded communal self-governance : a pre-modern solution for the modern world?

Shadi Hamid proposes “democratic minimalism” as a system and means of governing and rotating power with no prejudice to substantive ideological outcomes. Democratic minimalism is meant to decouple the question of actualizing an ideal society, even a liberal one that provides maximum freedom for the maximum groups of people, from the mechanism of transferring power between groups with opposing beli

In Vacuo XPS Study on Pt Growth by Atomic Layer Deposition Using MeCpPtMe3 and N2/NH3 Plasma

Atomic layer deposition (ALD) has been an attractive tool in the fabrication of Pt thin layers and nanoparticles. In this work, the surface chemistry of Pt ALD through the MeCpPtMe3/N2-plasma (N2*) and the MeCpPtMe3/NH3-plasma (NH3*) processes at 300 °C have been investigated in detail using in vacuo X-ray photoelectron spectroscopy (XPS) during the ALD process, so that the evolution of surface sp

A minute-resolution downscaling algorithm for high-resolution global irradiance time series

Numerous studies have demonstrated the significant impact of the resolution of solar irradiation data on the outcomes of hourly production models. Accurate integration of photovoltaic (PV) systems sometimes demands a high-resolution global horizontal irradiance (GHI) time series to capture the rapid fluctuations in PV power output induced by swift irradiance changes. Most of the available database

An evolving roadmap : using mitochondrial physiology to help guide conservation efforts

The crucial role of aerobic energy production in sustaining eukaryotic life positions mitochondrial processes as key determinants of an animal's ability to withstand unpredictable environments. The advent of new techniques facilitating the measurement of mitochondrial function offers an increasingly promising tool for conservation approaches. Herein, we synthesize the current knowledge on the link

Two-step acoustofluidic cancer cell enrichment

We have previously proposed and evaluated acoustophoresis for the enrichment of circulating tumor cells (CTC) and clusters thereof from the blood of patients with prostate cancer [1]. In that protocol, the cells were fixed and preserved in paraformaldehyde before processing and were thus non-viable. To enable future enrichment of also viable CTCs from patients, we have in this study investigated t

Kontinuitet och förändring: Essäer om spårbundenhet i samhället

Samtiden tycks besatt av det ögonblickliga: I kultur, politik och samhällsdebatt överdrivs individuella prestationer och snabba, omvälvande händelser. Detta trots att samhällsvetenskapen sedan länge har understrukit betydelsen av historiska utvecklingslinjer, och gång på gång visat att beslut idag är starkt präglade av tidigare händelser. Med andra ord: att samhällsutvecklingen är spårbunden.I den

Transient buildup and decay of thermoacoustic streaming

We recently introduced the concept of thermoacoustic streaming in microchannels wherein a thermal field is generated inside an acoustic cavity. The result is a fast and controllable streaming for which the thermal energy is provided either by an LED light source [1], or a laser [2]. While in previous works we have measured this effect at steady state, we now present measurements of the build-up an

Sound to guide cells

By combining acoustic fields and liquid flows in microchannels we develop tools to chart and separatebiological particles based on their bio-mechanical properties. I will present an overview of three ongoingprojects where acoustic forces are utilized to separate blood cells.We studied the packing behavior of whole blood in a sound field. We discovered that cells self-organizesuch that red blood cells

Evaluation of the 2023 Duke-ISCVID criteria for infective endocarditis in patients referred to the Lund infective endocarditis team

Background: The Duke criteria for diagnosing infective endocarditis (IE) were recently updated by the International Society for Cardiovascular Infectious Diseases (ISCVID) with the purpose of enhancing diagnostic specificity and sensitivity. This study investigated the performance of the Duke-ISCVID criteria in relation to previous criteria. Method: This retrospective single centre cohort study in

The Socioeconomics of Wind Power Expansion: Evidence from Sweden

We document the socioeconomics of wind power expansion in Sweden using two metrics. First, we compute the difference in socioeconomic status (SES) between residents exposed to wind power (0-2 km from the closest turbine) and those not exposed. For each site, the metric is computed ten years prior until five years after construction. When the comparison group is other residents within the same muniWe document the socioeconomics of wind power expansion in Sweden using two metrics.
