Pyrometallurgical Treatment of Apatite Concentrate with the Objective of Rare Earth Element Extraction: Part I
(Journal article, 2017)Apatite, Ca5(PO4)3F, concentrate from LKAB in Kiruna, Sweden, has been characterized and pyrometallurgically treated using (i) silicon metal and fluxes to extract phosphorus and transition metals at 1600 °C (Part I ... -
Pyrometallurgical Treatment of Apatite Concentrate with the Objective of Rare Earth Element Recovery: Part II
(Journal article, 2017)Apatite, Ca5(PO4)3F, is a useful raw material for the production of both elemental phosphorus and phosphoric acid, and the mine tailings present at Luossavaara-Kiirunavaara AB (LKAB) in Kiruna, Sweden, represent a significant ... -
Pyrrhotite in concrete aggregate. Introduction to mechanism, damage potential and ongoing research
(Chapter, 2022)Pyrrhotite is an iron sulfide which when present in concrete aggregate may lead to expansive reactions, cracks and finally disintegration of the concrete. This potential risk when using aggregates containing sulfides in ... -
Pyrrolopyrimidine based CSF1R inhibitors: Attempted departure from Flatland
(Peer reviewed; Journal article, 2024)The colony-stimulating factor 1 receptor (CSF1R) is an attractive target for inflammation disorders and cancers. Based on a series of pyrrolo[2,3-d]pyrimidine containing two carbo-aromatic rings, we have searched for new ... -
Pyruvate Supports RET-Dependent Mitochondrial ROS Production to Control Mycobacterium avium Infection in Human Primary Macrophages
(Peer reviewed; Journal article, 2022)Macrophages deploy a variety of antimicrobial programs to contain mycobacterial infection. Upon activation, they undergo extensive metabolic reprogramming to meet an increase in energy demand, but also to support immune ... -
PYY Plays a Key Role in the Resolution of Diabetes Following Bariatric Surgery in Humans
(Journal article; Peer reviewed, 2019)Background Bariatric surgery leads to early and long-lasting remission of type 2 diabetes (T2D). However, the mechanisms behind this phenomenon remain unclear. Among several factors, gut hormones are thought to be crucial ... -

PYY-Dependent Restoration of Impaired Insulin and Glucagon Secretion in Type 2 Diabetes following Roux-En-Y Gastric Bypass Surgery
(Journal article; Peer reviewed, 2016)Roux-en-Y gastric bypass (RYGB) is a weight-reduction procedure resulting in rapid resolution of type 2 diabetes (T2D). The role of pancreatic islet function in this restoration of normoglycemia has not been fully elucidated. ... -
Q-SEA – a tool for quality assessment of ethics analyses conducted as part of Health technology assessments
(Journal article; Peer reviewed, 2017)Introduction: Assessment of ethics issues is an important part of health technology assessments (HTA). However, in terms of existence of quality assessment tools, ethics for HTA is methodologically underdeveloped in ... -
QCD at finite isospin density: chiral perturbation theory confronts lattice data
(Peer reviewed; Journal article, 2020)We consider the thermodynamics of three-flavor QCD in the pion-condensed phase at nonzero isospin chemical potential (μI) and vanishing temperature using chiral perturbation theory in the isospin limit. The transition from ... -
QCD phase diagram in a constant magnetic background: Inverse magnetic catalysis: where models meet the lattice
(Peer reviewed; Journal article, 2021)Magnetic catalysis is the enhancement of a condensate due to the presence of an external magnetic field. Magnetic catalysis at T=0 is a robust phenomenon in low-energy theories and models of QCD as well as in lattice ... -

QoE Analysis of the Setup of Different Internet Services for FIFO Server Systems
(Journal article; Peer reviewed, 2018)Queueing systems following a first-in-first-out (FIFO) strategy are well understood and various results are known for the response time of the system. However, the question arises how the results look like when taking into ... -
QoE Beyond the MOS: An In-Depth Look at QoE via Better Metrics and their Relation to MOS
(Journal article; Peer reviewed, 2016)While Quality of Experience (QoE) has advanced very significantly as a field in recent years, the methods used for analyzing it have not always kept pace. When QoE is studied, measured or estimated, practically all the ... -
QoS-Aware Inter-Domain Connectivity: Control Plane Design and Operational Considerations
(Chapter, 2022)Scenarios related to 5G and beyond give rise to a high degree of heterogeneity in terms of applications, services, and user expectations as well as more demanding QoS requirements with an end-to-end scope that can cover ... -
Quadratic programming with ramp functions and fast online QP-MPC solutions
