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.

In previous years, the crisis communication literature has increasingly emphasised the need for closer examination of internal crisis communication, thereby focussing on employees during crises. Additionally, so far, no research has been conducted exploring internal crisis communication and its impact on employee well-being. The present study aimed at closing this gap by investigating whether inte
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
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
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
In this paper, technical and economic prerequisites to attain reduced carbon dioxide (CO2) emissions through the use of biomass-based energy carriers in the transportation sector are studied. CO2 emission reduction per unit of land used for biomass production as well as costs for CO2 emission reduction are estimated when substituting rape methyl ester, biogas from lucerne, ethanol from wheat and e
Within the paradigm of population dynamics a central task is to identify environmental factors affecting population change and to estimate the strength of these effects. We here investigate the impact of observation errors in measurements of population densities on estimates of environmental effects. Adding observation errors may change the autocorrelation of a population time series with potentia
Changes in tree and understory plant diversity and community composition in two sites at different disturbance levels were studied on the Anaikatty hills, Western Ghats. Systematic sampling using small scale permanent quadrates (50 x 20 m for trees, 5 x 5 m for shrubs/saplings, 1 x 1 m for herbs/seedlings) enumerated 3,376 individuals of trees (106 species), 8,599 of individuals shrubs (122 specie
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
High-resolution precision spectroscopy provides a multitude of robust techniques for probing exoplanetary atmospheres. We present multiple VLT/ESPRESSO transit observations of the hot-Jupiter exoplanet WASP-19b with previously published but disputed atmospheric features from lowresolution studies. Through spectral synthesis and modelling of the Rossiter-McLaughlin (RM) effect we calculate stellar,
A unique assemblage consisting of 113 pine samples collected from a submerged Mesolithic landscape in the Haväng area, southern Sweden, was examined to assess the presence of large herbivores, as well as changes in wild-game population density and composition. Bark-stripping damages on prehistoric trees is an extremely underutilized source of information about past game-population dynamics, yet ou
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
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
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
