Internal mixing on the giant branch is an important process which affects the evolution of stars and the chemical evolution of the galaxy. While several mechanisms have been proposed to explain this mixing, better empirical constraints are necessary. Here, we use [C/N] abundances in 26,097 evolved stars from the SDSS-IV/APOGEE-2 Data Release 14 to trace mixing and extra mixing in old field giants
Catalysis is one of the few scientific concepts that has entered common parlance. To laymen catalysts simply speed up processes, but to a chemist they are much more interesting and complex. Catalysis offers the possibility to accomplish chemical reactions in a targeted manner with the least expenditure of energy and material. Given the increasing scarcity of resources, catalysts have become relevaThis thesis deals with the design and synthesis of rhodium and iridium bis-η2 diolefin catalysts and their applications in C–C bond formation and asymmetric catalysis.More specifically, the second chapter describes the development of inter- and intramolecular (5+2) cycloadditions catalyzed by cationic iridium(I) complexes that lead to the formation of seven-membered rings in a single step. DFT was
Red giant stars are perhaps the most important type of stars for Galactic and extra-galactic archaeology: they are luminous, occur in all stellar populations, and their surface temperatures allow precise abundance determinations for many different chemical elements. Yet, the full star formation and enrichment history of a galaxy can be traced directly only if two key observables can be determined
Complex formation between Pd(II), Pt(II) and iodide has been studied at 25 °C for an aqueous 1.00 M perchloric acid medium. Measurements of the solubility of PdI2(s) in aqueous mercury(II) perchlorate and of AgI(s) and PdI2(s) in aqueous solutions of Pd2+(aq) and Ag+(aq) gave the solubility product of PdI2(s) as Kso=(7±3) × 10−32 M3, which is much smaller than previous literature values.The stabilComplex formation between Pd(II), Pt(II) and iodide has been studied at 25 °C for an aqueous 1.00 M perchloric acid medium.

The 2.5 km deep scientific COSC-1 borehole (ICDP 5054-1-A) was successfully drilled with nearly complete core recovery during spring and summer of 2014. Downhole and on-core measurements through the targeted Lower Seve Nappe provide a comprehensive data set. An observed gradual increase in strain below 1700 m, with mica schists and intermittent mylonites increasing in frequency and thickness, is h
OBJECTIVE: To study the influence of gestational age on lactate concentration in arterial and venous umbilical cord blood at birth and to define gestational age-specific reference values for lactate in vigorous newborns. DESIGN: Population-based comparative. SETTING: University hospitals. SAMPLE: Vigorous newborns with validated umbilical cord blood samples. MATERIAL AND METHODS: From 2000 to 2004
BACKGROUND: To evaluate the distal landing zone (LZ) outcomes in adverse morphology after thoracic endovascular repair (TEVAR) with distal active fixation (DAF) stent-grafts compared with standard endografts.METHODS: between 2006 and the 31st December 2020, sixty-nine DAFs (study group) and sixty-nine standard stent-grafts (control group) were enrolled in a multi-center, retrospective, case-contro
Objective. To explore long-term cardiovascular outcomes and mortality in patients after a first myocardial infarction (MI) compared with matched controls in a contemporary setting. Methods. During 2010–2014 the Swedish study PAROKRANK recruited 805 patients <75 years with a first MI and 805 age-, gender-, and area-matched controls. All study participants were followed until 31 December 2018, throu
Radium-226 carbonate was synthesized from radium-barium sulfate (226Ra0.76Ba0.24SO4) at room temperature and characterized by X-ray powder diffraction (XRPD) and extended X-ray absorption fine structure (EXAFS) techniques. XRPD revealed that fractional crystallization occurred and that two phases were formed─the major Ra-rich phase, Ra(Ba)CO3, and a minor Ba-rich phase, Ba(Ra)CO3, crystallizing in
Objectives: To characterize the utility of nitrotyrosine (NT) as a biomarker for arthritis and joint injury. Design: Synovial fluid, plasma, and urine from patients diagnosed with osteoarthritis (OA), rheumatoid arthritis (RA), anterior cruciate ligament (ACL) injury, meniscus injury and pseudogout, and knee-healthy volunteers were analyzed for concentrations of NT, nitrate and nitrite (NOx), matr
This thesis investigates machine learning-based control charts with Variable Pa- rameters(VP)formonitoringGeneralizedLinearModel(GLM)profiles. Previous studies have examined machine learning control charts under Fixed Parameters (FP) schemes for several GLM distributions, while VP schemes have mainly been studied for Binomial profiles with logit link. This thesis extends the VP frame- work to two
Plant-based meat analogs (PBMAs) are defined as foods formulated from plant proteins that imitate meat structure, flavor and physical appearance. In the past decade, the market for PBMA has increased nearly threefold with global retail sales of $6,6 billion in 2024 compared to $2,2 billion in 2015, as part of a broader shift toward a more plant-based diet. However, knowledge of the microbiological
This work applied Bayesian Optimization (BO) for the task of calibrating methane-related parameters in the Lund-Potsdam-Jena General Ecosystem Simulator (LPJ-GUESS v4.1). A Gaussian Process (GP) was used as the surrogate model within the BO framework. Additionally, other enhancements we applied to the BO framework such as the use of complexity-penalizing priors for GP hyperparameters and numerical
The Campanian marine strata from Åsen, north east part of the Kristianstad Basin (southern Sweden) contain a most diverse vertebrate and invertebrate marine fossil assemblages. A diverse fossil fauna was collected from Campanian deposits from a ca. 4.15m thick section during June-August 2010-2012. The succession is divided into two zones, the latest early Campanian Belemnellocamax mammilatus Zone

7 December 2020 to 17 February 2021 The ‘Red Room Project’ explores the displacement between a live performance and the echo thereof, in the performance ‘Red Room Institute’ and the sound installation ‘Use It Well’ (working titles). Inspired by the social phenomenon of ‘dancing epidemics’ in which groups of people were said to contaminate each other with compulsive dancing, the ‘Red Room Project’
