Aim: The aim of this study was to explore the role of managers and employees with an assigned responsibility (i.e. inspirers) when integrating recovery-enhancing activities into everyday work in a primary health care setting. Background: The possibility of recovery during the workday is essential for employee wellbeing. However, the literature on workplace interventions focusing on recovery is sca

Work loss in patients with rheumatoid arthritis treated with abatacept, rituximab, tocilizumab or TNF inhibitors : a nationwide direct drug-to-drug comparison

Objective To compare work loss after starting tumour necrosis factor inhibitors (TNFi), rituximab, abatacept or tocilizumab in patients with rheumatoid arthritis (RA). Methods We used data from the Swedish Rheumatology Quality Register to identify patients aged 19-62 years who were treated with TNFi (n=15 093), rituximab (n=2123), abatacept (n=1877) or tocilizumab (n=1720) between 2007 and 2020. D

Closed-Loop Switched Capacitor Cuk Converter Topology for Voltage Regulation and PFC Applications

Converters of AC-DC nature are pivotal to supplying power in electronics, charging equipment, and renewable energy integration. A closed-loop Cuk converter with switched capacitor network and PID controller was proposed in this paper to mitigate the limitations of open circuit Cuk converter topology to ensure improved power factor from input along with low distortion in output, making it ideal for

Julian Huxley, Evolutionism and the History of Transhumanism

The evolutionary biologist Julian Huxley (1887–1975) attempted to promote a “religion for the future,” which he would come to refer to as Transhumanism. Transhumanism was an attempt to unite a more traditional humanistic view of the human as containing some form of core essence or potential with an evolutionary point of view of humans as a work in progress. Before humans, natural selection had bee

An Evaluation of the Environmental Impact of Circular Facade Systems

With increasing environmental awareness, building materials and their impact on the environment are increasingly coming into focus. This study presents a framework for comparing Life Cycle Assessment (LCA) through A1 - A5 stages from the perspective of Global Warming Potential (GWP) to assess the climate change potential of three facade systems of different building types (villas, medium-sized bui

Checkmate : Orthodox Diplomacy in Montenegro and Macedonia in the Shadows of the War in Ukraine

In 2022 the Serbian Orthodox Church managed to seal off two of its longstanding ecclesial conflicts in former Yugoslavia and put an end to open hostility. The end of the conflicts seems to have been prompted as a response to the War in Ukraine. This chapter explores the Orthodox diplomacy in Montenegro and Macedonia and how it relates to the geopolitical and ecclesial role of the Serbian Orthodox

The functional and structural diversity of rhythmic communication across species

Research on the rhythmic communication (RC) of nonhuman animals is undergoing a period of great effervescence and expansion. Here, we synthesize this rapidly growing literature with the aim of mapping RC forms and usage contexts in an unprecedented diversity of taxa, spanning insects, fish, frogs, birds and mammals. We see this as a first large-scale effort toward charting the functional and struc

Diasporas’ political mobilisation for a ‘Homeland’ political party : The case of Turkey’s peoples’ democratic party in Germany and France

Abstract in French:Cette recherche s'intéresse à la mobilisation transnationale de la diaspora autour du vote externe et à l'implication des organisations diasporiques dans le processus électoral du pays d'origine. Plusieurs approches expliquent la transnationalisation politique des groupes diasporiques ; cependant, elles ne parviennent pas à clarifier (1) comment certains moments historiques (parThis research is concerned with transnational diaspora mobilisation around external voting and diaspora organisations’ involvement in the homeland electoral process. There are several approaches that explain the political transnationalisation of the diasporic groups; yet, they fail to clarify (1) how some historical moments (e.g., extending the voting right to non-resident nationals) can generate

Stable CO2 Hydrogenation to Methanol by Cu Interacting with Isolated Zn Cations in Zincosilicate CIT-6

The catalytic conversion of carbon dioxide (CO2) to methanol over Cu/ZnO catalysts is expected to become valuable for recycling CO2. The nature of the Cu-Zn interplay remains a subject of intense debate due to many different Zn species encountered in Cu/ZnO catalysts. In this study, we designed a Cu-Zn catalyst by ion-exchanging Cu into CIT-6, a crystalline microporous zincosilicate with the BEA*

What contributes to out-of-pocket health expenditure in Cambodia's uncovered population? A distributional and decomposition analysis using survey data

Introduction: Out-of-pocket health expenditures (OOPE) are an inefficient and inequitable means of health financing. Identifying the factors driving these expenditures is crucial to design effective prepayment schemes. This study uses Cambodia—a country with high OOPE and prevalent informal employment—as a case study to analyse the relative contributions of healthcare, health, and social factors t

Knowledge Distillation for Improved Spoof Detection

Artificiell intelligens blir alltmer populärt och används idag från allt till datorseende och självkörande bilar till chatbot assistenter som OpenAI:s världskända ChatGPT. Kärnan bakom dagens stora boom i artificiell intelligens är neurala nätverk, som blev möjligt att använda på grund av en stor utveckling i uträkningskraft med grafikkort. Neurala nätverk behöver astronomiska summor med uträkningAs deep neural networks grow more powerful, they also require more computational resources, which becomes a challenge when deploying on edge devices with limited computational capacity. This thesis looks into knowledge distillation, a model compression technique where a large "teacher" network transfers its learned features to a smaller "student" network. Our goal is to maintai

How animals produce rhythm : an overview of ethological mechanisms for rhythmic communication

Animals communicate with a staggering diversity of rhythmic signals, yet behind all this diversity lies a small number of ethological mechanisms. In this chapter, we provide a quick review of how animal produce rhythmic signals based on these mechanisms, which span tremulation, percussion, bodily displays, stridulation, tymbalation, aerodynamic sound production (including vocalisation), as well as

Small-scale rainwater cistern system for rainwater collection in north-western China

Despite the overall rapid economical development during the last decade in China, a number of regions in remote areas are still striving to alleviate poverty. These regions are commonly characterized by low level of industrialization, poorly developed agriculture, which almost entirely relies on climate situations. Water has often been a bottle-neck in the development of the agricultural, industri

Method Development for PKM2 Activity Analysis in Cancer-Associated Signaling Pathways

Introduction: PARP14 belongs to the superfamily of PARPs that perform ADP-ribosylation of target proteins. The enzyme is involved in many cellular processes, including regulation of glycolysis, protein degradation, and genomic reparation. Background: PKM2 has been shown to be regulated indirectly by PARP14 to promote the Warburg effect. This describes an alternative glycolysis that cancer cells a

Synthesis of palladium complexes and their antimalarial properties

En av de sjukdomar som påverkar flest människor årligen är malaria. Malaria sprids av myggor som bär på parasiten och när de biter en människa överförs parasiten till människan. Vanliga symptom vid en malariainfektion är lätt feber, frossa och huvudvärk. Dessa symptom kan bli allvarligare om personen är gravid, ett barn mindre än fem år gammalt, eller har HIV eller AIDS, eftersom sådana personer tMalaria is a well-known disease and affects large regions around the world. Medicines used for treatment already exist, but due to increasing resistance and unpleasant side effects it has become critical to develop new drug candidates. Several palladium complexes were synthesised and studied to understand their properties for treating malaria. The ligands and the complexes were synthesised and cha

Learning together in a global pandemic : practices and principles for teaching and assessing online in uncertain times

The higher education sector has been massively disrupted by COVID-19. The technological changes of the past two decades have enabled a ‘blended learning’ approach. Nonetheless, most academics were not prepared to become fully online teachers with very short notice (nor were most students prepared to learn online) in 2020. Our aim was to investigate and document changes in teaching from the perspec
