α-deuterated carboxylic acids have been synthesized from the corresponding malonic acids via hydrogen/deuterium exchange and decarboxylation in presence of D2O. The method is general, mild and efficient and does not require organic solvents or other additives. Yields range between 83% and 94% and purification was not necessary. Starting materials were easy accessible and the α-deuterated carboxyli
With the increase in the number of antennas at base stations (BSs), centralized multi-antenna architectures have encountered scalability problems from excessive interconnection bandwidth to the central processing unit (CPU), as well as increased processing complexity. Thus, research efforts have been directed towards finding decentralized receiver architectures where a part of the processing is pe
Microalgal biomass may have biostimulating effects on plants and seeds due to its phytohormonal content, and harnessing this biostimulating effect could contribute to sustainable agriculture. Two Nordic strains of freshwater microalgae species Chlorella vulgaris and Scenedesmus obliquus were each cultivated in a photobioreactor receiving untreated municipal wastewater. The algal biomass and the su
Given the increasing prevalence of problematic gaming, in 2013, the diagnosis “Internet gaming disorder (IGD)” was included in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) as a potential diagnosis. With a new diagnosis, it is important to determine treatment options. The importance of the parent–child relationship has been emphasised in problematic gaming and its
The aim of this work is to investigate the planar LIF/Mie droplet sizing technique from an experimental and theoretical point of view. This technique is a good alternative compared to point measurements (e.g., phase Doppler anemometry) or integral approaches (e.g., laser diffraction). It allows measurement of the Sauter mean diameter over a wide field, providing the spray topology and droplet size
This innovative book argues that meetings are a crucial feature of modern organisations, demonstrating that, contrary to popular belief, meetings are what define, represent and maintain organisations. Through an in-depth analysis of ethnographic case studies, Patrik Hall, Malin Åkerström and Erika Andersson Cederholm illustrate the inner workings of meetings, exploring phenomena such as meeting ch
Context. The Gaia DR3 catalogue contains, for the first time, about 800 000 solutions with either orbital elements or trend parameters for astrometric, spectroscopic, and eclipsing binaries, and combinations of these three. Aims. With this paper, we aim to illustrate the huge potential of this large non-single-star catalogue. Methods. Using the orbital solutions and models of the binaries, we have
This paper proposes a ‘tool for thinking with’1: that we can describe the interaction between peopleand computers, and especially people and developer tools, as a form of conversation. We outline thisperspective, construct a work in progress analytical frame, and use it to talk about a couple of differentexamples and draw implications for future work.
Striving to mitigate climate change, the European Union has adopted net-zero greenhouse gas emissions as a target for 2050. In this paper, European chemical industry roadmaps from the past six years are assessed and compared to uncover how the industry envisions its role in the transition to net-zero emissions. The roadmaps are assessed in terms of ambition level, technology and feedstock strategi
Inexpensive and efficient desalination is becoming increasingly important due to dwindling freshwater resources in view of climate change and population increase. Improving desalination techniques of brackish water using graphene-based materials has the possibility to revolutionize freshwater production and treatment. At the same time, graphene matter can be cheaply mass-produced from biowaste mat
Digital transformations have significant consequences for organizational attempts to shape their environments. Our focus is on how corporate political activity evolves in ways that require us to pay more attention to how information gets structured in digital spaces, and on how information ecosystems operate and shape strategic communication activities in organizational settings. We outline these
The automation of map labeling is an ongoing research challenge. Currently, the map labeling algorithms are based on rules defined by experts for optimizing the placement of the text labels on maps. In this paper, we investigate the feasibility of using well-labeled map samples as a source of knowledge for automating the labeling process. The basic idea is to train deep learning models, specifical
Welfare capitalism has developed in the context of rapidly expanding, fossil fuel-driven industrial economies. Faced with the urgent need for systematic changes of economic systems so that they stay within planetary limits, decoupling welfare from economic growth is an important task. This chapter introduces the concept of sustainable welfare, referring to welfare systems that prioritise the satis
Implantable cell replacement therapies promise to completely restore the function of neural structures, possibly changing how we currently perceive the onset of neurodegenerative diseases. One of the major clinical hurdles for the routine implementation of stem cell therapies is poor cell retention and survival, demanding the need to better understand these mechanisms while providing precise and s
Driving automation systems, including autonomous driving and advanced driver assistance, are an important safety-critical domain. Such systems often incorporate perception systems that use machine learning to analyze the vehicle environment. We explore new or differing topics and challenges experienced by practitioners in this domain, which relate to requirements engineering (RE), quality, and sys
