Infrared spectroscopy of cool giants

Purpose: To get a clearer picture of the structure and evolution of our Galaxy, astronomers are trying to reach further and further beyond the Solar neighborhood with their observations. The dust obscuration towards the center of the Milky Way necessitates the use of infrared wavelengths for this, and cold giants provide a particularly bright and thus useful target. However, any methods for analyz

Pathogen Contamination of Groundwater Affecting Drinking Water Quality with Potential Health Effects in Pavlodar Region, Kazakhstan

Groundwater is becoming increasingly important as surface water is decreasing and becoming more and more polluted. In particular, rural areas in the arid region of Central Asia face problems with both water quantity and quality. In view of this, we investigated the drinking water quality in the Maysky district in the Pavlodar region, Kazakhstan. The organoleptic properties, together with microbiol

Multistakeholder Partnerships and the 2030 Agenda for Sustainable Development: Sources and Audiences of Self-legitimation in the Fields of Health and Climate

The spread of global multistakeholder partnerships (MSPs) for the2030 Agenda for sustainable development has generatedsignificant expectations on policy synergies and transformativegovernance. This article contributes to the study of the currentgeneration of MSPs by focusing on the self-legitimation attemptsthat MSPs undertake to justify their authority. We compare theself-legitimation claims of a

Natural marine aerosols : A study on atmospheric chemistry, new particle formation and particle growth

The role of natural marine aerosols in the global climate system remains understudied and uncertain. This is true for the emissions of natural volatile compounds over the ocean, the oxidation of said compounds and their impact on particle formation and particle growth. In this thesis, the emission, chemistry and aerosol particle processes relating to these compounds were studied using different pr

Energy, economic, and environmental assessment of a solar-assisted heat pump system in Germany

Denna studie undersöker en parallell indirekt solassisterat värmepump (SAVP) för ett typiskt hushåll i Tyskland. Systemet utgörs av fotovoltaisk-termiska (FVT) solfångare och en värmepump (VP) för att täcka behovet av värme, varmvatten och hushållsel genom att använda solvärme, solel och nätel. Syftet var att utvärdera SAVP-systemets prestanda i Tysklands tre största städer för olika VPar med olikThis study investigates a parallel indirect Solar-Assisted Heat Pump (SAHP) system for a typical household in Germany. The system integrates Photovoltaic-Thermal (PVT) collectors and a heat pump (HP) to meet space heating, domestic hot water, and appliance electricity demands using solar thermal energy, solar electrical energy, and grid electricity. The objectives were to evaluate the thermodynami

Optimizing the Sensitivity of a Pelvic Sentinel Node Algorithm Requires a Hybrid Algorithm Combining Indocyanine Green Based Mapping and the Removal of Non-Mapped Nodes at Defined Anatomic Positions

AIM OF THE STUDY: to investigate the incidence of non-mapped isolated metastatic pelvic lymph nodes at pre-defined anatomical positions.PATIENTS AND METHODS: Between June 2019 and January 2024, women with uterine-confined endometrial cancer (EC) deemed suitable for robotic surgery and the detection of pelvic sentinel nodes (SLNs) were included. An anatomically based, published algorithm utilizing

A novel end-to-end dual-camera system for eye gaze synchrony assessment in face-to-face interaction

Quantification of face-to-face interaction can provide highly relevant information in cognitive and psychological science research. Current commercial glint-dependent solutions suffer from several disadvantages and limitations when applied in face-to-face interaction, including data loss, parallax errors, the inconvenience and distracting effect of wearables, and/or the need for several cameras to

A novel tablet-based motor coordination test performs on par with the Beery VMI subtest and offers superior temporal metrics : findings from children with pediatric acute-onset neuropsychiatric syndrome

Neuropsychiatric and neurodevelopmental disorders are often associated with coordination problems. Pediatric Acute-onset Neuropsychiatric Syndrome (PANS) constitutes a specific example of acute and complex symptomatology that includes difficulties with motor control. The present proof-of-concept study aimed at testing a new, bespoke tablet-based motor coordination test named SpaceSwipe, providing

Pupil contagion variation with gaze, arousal, and autistic traits

Pupillary contagion occurs when one's pupil size unconsciously adapts to the pupil size of an observed individual and is presumed to reflect the transfer of arousal. Importantly, when estimating pupil contagion, low level stimuli properties need to be controlled for, to ensure that observations of pupillary changes are due to internal change in arousal rather than the external differences between

Engineering Af1521 improves ADP-ribose binding and identification of ADP-ribosylated proteins

Protein ADP-ribosylation is a reversible post-translational modification that regulates important cellular functions. The identification of modified proteins has proven challenging and has mainly been achieved via enrichment methodologies. Random mutagenesis was used here to develop an engineered Af1521 ADP-ribose binding macro domain protein with 1000-fold increased affinity towards ADP-ribose. T

Designing from biobased to closed-loop circularity: Flexible dynamic polyimine-amide networks

Dynamic polyimine-amide networks with exceptional properties, including high flexibility, excellent thermal stability and dual closed-loop circularity were designed by combining dynamic covalent imine-functionalities with amide-chemistry. The solvent free up-scalable synthesis started from carboxyl-functionalization of lignin-derivable aldehydes followed by melt polycondensation with a triamine to

A Focused DNA-Encoded Chemical Library for the Discovery of Inhibitors of NAD+-Dependent Enzymes

DNA-encoded chemical libraries are increasingly used in pharmaceutical research because they enable the rapid discovery of synthetic protein ligands. Here we explored whether target-class focused DNA-encoded chemical libraries can be cost-effective tools to achieve robust screening productivity for a series of proteins. The study revealed that a DNA-encoded library designed for NAD+-binding pocket

On Swedish and Australian employer’s attitudes to recruiting welfare clients and the role of stigma. A working paper.

This comparative study delves into the intricate challenges surrounding stigma within active labor market programs (ALMPs) and its implications for work, wellbeing, and social policy. In both Sweden and Australia, employers exhibit reluctance to draw from this candidate pool for recruitment. Understanding employers' reasons for not utilising ALMP candidates, their expectations from candidates, and

Converting Commodity Swaps to net futures-equivalent: Staying compliant with CFTC:s new position limits on Economically Equivalent Swaps

Trading commodities has been around for centuries, and today, most trading is done electronically on exchanges in derivatives contracts. Over time, regulatory bodies, specifically the CFTC, have sought to implement safeguards against market manipulation by participants. One such measure has been position limits on derivatives, which since January 1st, 2023, also includes so-called economically equ

Testing Measures for Degree of PIT-ness in PD models

This thesis explores the Point-in-Time (PIT) in probability of default (PD) models, focusing on evaluating the degree of PIT-ness. Unlike previous studies that developed new measures for PIT characteristics, this research compares existing measures and frameworks to identify unique challenges and opportunities. By analyzing and testing existing measures for 1-year PD models, the study offers new i

Altruism and natural selection in a variable environment

Hamilton’s rule provides the cornerstone for our understanding of the evolution of all forms of social behavior, from altruism to spite, across all organisms, from viruses to humans. In contrast to the standard prediction from Hamilton’s rule, recent studies have suggested that altruistic helping can be favored even if it does not benefit relatives, as long as it decreases the environmentally indu
