Modelling ZnCl2 solutions for quality control in a textile recycling pilot plant

Kvalitetskontrollsmodell för textilåtervinning 2025 infördes en EU-lag som gjorde det obligatoriskt att sortera textilavfall separat. Här presenteras grunden för en modell som relaterar reaktorparametrar till kvalité på återvunnen textilmassa. Textilindustrin omfattade 2024 knappt 2 biljoner USD. Det är en global industri där textilierna ofta designas i USA, produceras i asiatiska länder och slutTextile recycling is highly needed as great amounts of waste are produced every year and most of it is put into landfill or incinerated. This thesis lays the foundations for a quality control system which may be applied for controlling the recycling of cellulosic textiles in an upcoming pilot plant based on ShareTex’s technology. The quality control system was constructed as a mathematical model r

SGLT2 inhibitors for patients with type 2 diabetes mellitus after myocardial infarction : a nationwide observation registry study from SWEDEHEART

The main outcome was oral glucocorticoid withdrawal. A McNemar test was us

Dwell time delays for commuter trains : An analysis of the influence of passengers on dwell time delays

The thesis presented here delves into why dwell time delays for commuter trains occur, with a specific focus on the impact of boarding and alighting passengers. The overarching aim is to develop knowledge of how time delays arise to identify and describe potential ways in which dwell time delays can be reduced. In addition to this, a secondary aim is to identify how dwell times can be studied on a

Postdiagnosis Statin Use and Breast Cancer Mortality

The Similarity of Abundance Ratio Trends and Nucleosynthetic Patterns in the Milky Way Disk and Bulge

We compare abundance ratio trends in a sample of ∼11,000 Milky Way bulge stars (R GC < 3 kpc) from the Apache Point Observatory Galactic Evolution Experiment (APOGEE) to those of APOGEE stars in the Galactic disk (5 kpc < R GC < 11 kpc). We divide each sample into low-Ia (high-[Mg/Fe]) and high-Ia (low-[Mg/Fe]) populations, and in each population, we examine the median trends of [X/Mg] versus [Mg/

RESEARCH DESIGN AND METHODS: A comprehensive preconception-to-pregnancy management plan for women with T1D was implemented in 11 centers from 8 Chinese cities from 2015 to 2017. Se

Cost-effectiveness of adding a non-invasive acoustic rule-out test in the evaluation of patients with symptoms suggestive of coronary artery disease : Rationale and design of the prospective, randomised, controlled, parallel-group multicenter FILTER-SCAD trial

Most patients with symptoms suggestive of chronic coronary syndrome (CCS) have no obstructive coronary artery disease (CAD) and better selection of patients to be referred for diagnostic tests is needed. The CAD-score is a non-invasive acoustic measure that, when added to pretest probability of CAD, has shown good rule-out capabilities. We aimed to test whether implementation of CAD-score in clini

Efficient Assignment of Identities in Anonymous Populations

We consider the fundamental problem of assigning distinct labels to agents in the probabilistic model of population protocols. Our protocols operate under the assumption that the size n of the population is embedded in the transition function. Their efficiency is expressed in terms of the number of states utilized by agents, the size of the range from which the labels are drawn, and the expected n
