Polyfluorenes Bearing N,N-Dimethylpiperidinium Cations on Short Spacers for Durable Anion Exchange Membranes

Alicyclic quaternary ammonium cations having all the β-protons in a strain-free ring structure are in general highly base resistant, and are thus very attractive to employ for anion exchange membrane (AEM) applications. However, tethering cations such as N,N-dimethylpiperidinium (DMP) to polymer backbones without introducing any weak links is quite challenging. In the present study, we have attach

PREDICTION OF REAL-TIME TRAIN ARRIVAL TIMES ALONG THE SWEDISH SOUTHERN MAINLINE

Real-time train arrival time prediction is crucial for providing passenger information and timely decision support. The paper develops methods to simultaneously predict train arrival times at downstream stations, including direct multiple output liner regression (DMOLR) and seemingly unrelated regression (SUR) models. To capture correlations of prediction equations, two bias correction terms are t

Den postreformatoriska katolicismen i Norden : Mission, konversion och alternativa identitetsdiskurser

This article summarizes and discusses some results of my earlier research focusing on the Catholic mission in Scandinavia and the alternative identity discourses that this missionary activity created. It also discusses Catholic gender discourses and ideals of masculinity. The Nordic countries were subjected to Catholic missionary activity, aimed at bringing the Nordic peoples to convert to the CatThis article summarizes and discusses some results of my earlier research focusing on the Catholic mission in Scandinavia and the alternative identity discourses that this missionary activity created.

An R package of maximum entropy production model to estimate 41 years of global evapotranspiration

An accurate estimation of evapotranspiration (ET) is vital for understanding the global hydrological cycle. However, large uncertainties in the present global ET products originate from the distinct model structures, assumptions, and inputs. The maximum entropy production (MEP) model provides a novel method for modeling ET based on parsimonious inputs and energy conservation. In this study, an R p

Exhaled phospholipid transfer protein and hepatocyte growth factor receptor in lung adenocarcinoma

BACKGROUND: Screening decreases mortality among lung cancer patients but is not widely implemented, thus there is an unmet need for an easily accessible non-invasive method to enable early diagnosis. Particles in exhaled air offer a promising such diagnostic tool. We investigated the validity of a particles in exhaled air device (PExA) to measure the particle flow rate (PFR) and collect exhaled br

Negative Pressure Wound Therapy for the Prevention of Surgical Site Infections Using Fascia Closure After EVAR-A Randomized Trial

BackgroundSurgical site infections (SSI) in the groin after vascular surgery are common. The aim of the study was to evaluate the effect of negative pressure wound therapy (NPWT) on SSI incidence when applied on closed inguinal incisions after endovascular aneurysm repair (EVAR).MethodsA multicenter randomized controlled trial (RCT). Between November 2013 and December 2020, 377 incisions (336 bila

Aural Transposition : Psychogeography and the Ephemeral World

Aural transposition sits at a crossroads between being a tool for practice and creating work, and being a tool that illuminates aspects of another entity. In day-to-day music practice, transposition can be an age-old tool for learning material, or a multi-layered exploration of an object or place. Transposition can also be a means of recreating places, real or imagined, through the transposition o

Advances in X-ray crystallography methods to study structural dynamics of macromolecules

X-ray crystallography has long been a key method in solving the three-dimensional structure of proteins. Structural information is essential for unraveling the molecular function of proteins and structure-based drug design. However, there are several obstacles associated with the structural determination of proteins using X-ray crystallography, such as the generation of a large amount of protein s

When only China wants to play : Institutional turmoil and Chinese investment in Brazil

The political and institutional crisis in Brazil from 2015, fueled largely by corruption probes and lawfare, had severe repercussions within the Brazilian construction and energy sectors. While many international investors withdrew from Brazil in this period, Chinese investment surged. This article accounts for the particular characteristics of Chinese investments, such as sectorial complementarit

Energy-efficient lighting and visually impaired users in homelike environments

Despite a rapid transition to LED lamps, it is still little knowledge about the effects of these light sources on users with low vision. The study's main objective was to acquire a better understanding about how correlated colour temperatures (CCTs) of non-directional LED affect visual accessibility and perceptions of lighting quality in homelike environments among visually impaired persons. The s

Agreement Between Isokinetic Dynamometer and Hand-held Isometric Dynamometer as Measures to Detect Lower Limb Asymmetry in Muscle Torque After Anterior Cruciate Ligament Reconstruction

Two commonly used instruments to assess muscle strength after anterior cruciate ligament reconstruction are the isokinetic dynamometer, which measures isokinetic torque and the hand-held dynamometer, which measures isometric torque. Isokinetic dynamometers are considered superior to other instruments but may not be commonly used in clinical settings. Hand-held dynamometers are small, portable, and

Path tracing in the study of agency and structures : Methodological considerations

Despite the rapidly expanding literature on agency in regional development, the methodological approaches available to study it have not followed theoretical development and empirical studies. This article aims to shed light on methodological issues related to the study of path dependence, path creation and agency. The article’s main purpose is to construct a methodology - path tracing - that woul

The role of super-spreaders in modeling of SARS-CoV-2

In stochastic modeling of infectious diseases, it has been established that variations in infectivity affect the probability of a major outbreak, but not the shape of the curves during a major outbreak, which is predicted by deterministic models (Diekmann et al., 2012). However, such conclusions are derived under idealized assumptions such as the population size tending to infinity, and the indivi

The prognosis of schizophrenia : A systematic review and meta-analysis with meta-regression of 20-year follow-up studies

Objective: The aim was to examine the general outcome of schizophrenia after 20 years or more. Methods: Using the PRISMA guidelines, we conducted a systematic review and meta-analysis with meta-regression on long-term follow-up studies of schizophrenia up until April 21, 2021. We included prospective studies with at least 20 years of follow-up on patients with a diagnosis of schizophrenia, and the

Emotional labour in digital diplomacy: perceptions and challenges for European diplomats

Social media are increasingly important tools in diplomacy. Diplomats are expected to use social media platforms such as Twitter, Facebook and Instagram to communicate with each other and with both domestic and international publics. This form of communication involves displaying positive emotions to generate attention in a competitive information environment. Emotions are essential to managing pe

A comparison study on patient-reported outcome between obese and non-obese patients with central lumbar spinal stenosis undergoing surgical decompression : 14,984 patients in the National Swedish Quality Registry for Spine Surgery

Background and purpose — Obesity has been associated with inferior outcomes after laminectomy due to central lumbar spinal stenosis (CLSS); we evaluated whether this occurs in surgery on national bases. Patients and methods — We retrieved pre-and 1-year postoperative data from the National Swedish Quality Registry for Spine Surgery regarding patients aged ≥ 50 with laminectomy due to CLSS in 2005–

Surface-Functionalized Polystyrene Nanoparticles Alter the Transmembrane Potential via Ion-Selective Pores Maintaining Global Bilayer Integrity

Although nanoplastics have well-known toxic effects toward the environment and living organisms, their molecular toxicity mechanisms, including the nature of nanoparticle-cell membrane interactions, are still under investigation. Here, we employ dynamic light scattering, quartz crystal microbalance with dissipation monitoring, and electrophysiology to investigate the interaction between polystyren
