Lead-free layered double perovskite nanocrystals (NCs), i.e., Cs4M(II)M(III)2Cl12, have recently attracted increasing attention for potential optoelectronic applications due to their low toxicity, direct bandgap nature, and high structural stability. However, the low photoluminescence quantum yield (PLQY, <1%) or even no observed emissions at room temperature have severely blocked the further deve

The purposes of this article-based thesis are to explore and understand preaching as a practice in general, and the practice of preaching in digital culture and spaces in particular. Informed by the practice theory of Theodore Schatzki, it presents the results of a cross-case analysis of four different case studiesof the practice of preaching in digital culture and spaces in Swedish protestant chu

Growth of cities has caused the climate in them to change making urban areas warmer than the surrounding rural areas. This phenomenon is called an urban heat island. Mitigation tactics to counter the heating of the urban areas vary from changing the thermal properties of the surface materials to adding vegetation and water bodies to the urban scene. This study aims to investigate the impact green

Intensity-modulated radiation therapy (IMRT) has during the recent years become a frequently used technique in radiotherapy. Lately IMRT has also been combined with rotational beam delivery, with a simultaneously moving couch, a technique called tomotherapy. The great benefit with this treatment method is the ability to give highly conformal treatments, with high dose to the tumour, while sparing

In this paper we present new optimization formulations for maximizing the network lifetime in wireless mesh networks performing data aggregation and dissemination for machine-to-machine communication in the Internet of Things. We focus on heterogeneous networks in which multiple applications co-exist and nodes may take on different roles for different applications. Moreover, we address network rec

During the 1970s, vocabulary knowledge was a central topic within the field of Swedish sociolinguistics, often discussed from a democratic point of view focusing on inclusion and accessibility in the society. This study links up to this tradition by reporting a survey of how the vocabulary knowledge has changed over time in Sweden, building on data from theSwedish Scholastic Aptitude Test (SweSAT)During the 1970s, vocabulary knowledge was a central topic within the field of Swedish sociolinguistics, often discussed from a democratic point of view focusing on inclusion and accessibility in the society.

Introduction: Older adults spend more time at home after retirement, and the home becomes a central place for activity. While research indicates that indoor lighting, exposure to daylight, physical activity and sleep interact to influence functioning, mood and daily rhythm, strategies are needed to promote behavioural changes to optimise these factors in daily life. The objective is to design an i

According to the World Health Organization Wheelchair Provision Guidelines (2023) wheelchair training is a critical component of the wheelchair provision process. In fact, the guidelines ‘strongly recommend’ that training for power and manual wheelchairs needs to be provided to enable maximum use and prevent abandonment and secondary injuries. Moreover, task-specific training is particularly encou

α-Synuclein (αSyn) is a neuronal protein predominantly found at the synapse, involved in vesicle trafficking. αSyn aggregates are also the main component of Lewy bodies, the hallmarks of Parkinson’s disease. Interactions between the N- and C-termini of αSyn play crucial roles in its behavior in solution, membrane binding, and aggregation. Studying these interactions provides valuable insights
