Understanding the nature and origin of the precursor material to terrestrial planets is key to deciphering the mechanisms and timescales of planet formation1. Nucleosynthetic variability among rocky Solar System bodies can trace the composition of planetary building blocks2–5. Here we report the nucleosynthetic composition of silicon (μ30Si), the most abundant refractory planet-building element, i

This paper discussed construction industry’s ongoing battle with gender equality. Growing awareness of social sustainability responsibility has led to the mounting importance of human resources in the organisations. One perspective involves the focus on gender equality. Today women’s participation in the construction industry is still low except in times of acute labour shortages. This disproporti

Volunteer tourism is an alternative form of tourism that is constantly increasing. The increase can be considered related to trends about social participation, environmental awareness and moral demands. Volunteering in developing countries has previously been associated with altruism and social responsibility, but more recently volunteer organizations have used personal development as part of thei

Turkey, the country of failed and "successful" military coups, experienced the latest coup attempt on July 15, 2016, in which it is still unclear how, why, and by whom it originated. However, after this critical event, Turkish media and critical journalists were subjected to very strict censorship and repression. Hundreds of journalists were arrested for their views, and many had to flee

After realising vibrato is such an essential resource in strings and it can affect the quality of sound, I decided to reflect on it. The thesis is divided into two source parts, Vibrato subdivided in definition, terminology, evolution and the four main types and Dvořák subdivided in a brief composer's biography, the evolution in his aesthetics, and the context of composition of the concerto, o

English is today learnt in multitudes of settings worldwide, making it difficult to characterize relationships between motivation and context in generalized terms (Ushioda 2013). In settings where students have extensive encounters with English outside school, a reluctance to invest effort in formal learning has been observed. To investigate ways in which out-of-school encounters impact on motivat

Glucagon-like peptide-1 (GLP-1) receptor agonists are established pharmaceutical therapies for the treatment of type 2 diabetes and obesity. They mimic the action of GLP-1 to reduce glucose levels through stimulation of insulin secretion and inhibition of glucagon secretion. They also reduce body weight by inducing satiety through central actions. The GLP-1 receptor agonists used clinically are ba

With roots in social psychology, second language (L2) motivation has largely been investigated using self-report techniques. Studies drawing on observational data gathered in contexts where learning takes place are rare, and understandings of how motivation evolves in classroom interactions remain limited (Boo, Dörnyei, & Ryan, 2015). In a position paper in Language Teaching, Ushioda (2016) ma

Historically and traditionally, military work has been closely associated with men. However, the post-Cold War normalization process has brought about a transformation in both the Swedish Armed Forces themselves and the perception of the organization. Normative concerns, including gender equality, have gained significant prominence, compelling the armed forces to embark on various initiatives aime

Pteropodidae is the only phytophagous bat family that predominantly depends on visual and olfactory cues for orientation and foraging. During daytime, pteropodids of different species roost in sites with varying light exposure. Pteropodids have larger eyes relative to body size than insectivorous bats. Retinal topography has been studied in less than 10% of the approximately 200 pteropodid species

Any ultrafast optical spectroscopy experiment is usually accompanied by the necessary routine of ultrashort-pulse characterization. The majority of pulse characterization approaches solve either a one-dimensional (e.g., via interferometry) or a two-dimensional (e.g., via frequency-resolved measurements) problem. Solution of the two-dimensional pulse-retrieval problem is generally more consistent d

A fair distribution of accessibility to key activities is a central concern for distributive justice in transport planning. This implies that disparities in accessibility and the negative effects associated with a lack of accessibility should be mitigated. However, even though accessibility is not purely spatial or static, it is conventionally treated as if it were. Several studies have significan

Brownification of surface waters, or browning, describes the increase of water colour in water systems. This phenomenon occurs due to an increase in dissolved organic carbon and iron concentrations. Browning is a major environmental concern, as it has negative effects on both water quality, and therewith the drinking water production, and the health of aquatic ecosystems. The aim of two research p

Pramipexole is a medication that normalises dopamine signalling in the brain. Previous studies have suggested that pramipexole is an effective treatment option for depression and anhedonia because it targets the dopaminergic pathways within the brain’s reward network. The nucleus accumbens is a crucial region for dopamine signalling in reward processing. Both task-based and resting-state fMRI evid

I denna uppsats undersöker jag mötet mellan AI och utomobligatorisk ska-deståndsrätt ur ett EU-perspektiv. Jag presenterar två föreslagna direktiv och diskuterar hur dessa kompletterar varandra för att skapa en lagstiftning som är lika effektiv i tekniskt komplicerade fall där rekvisiten är svårare att uppfylla. Jag undersöker också konceptet regulatorisk sandlåda, dess förde-lar ur ett utvecklarpIn this paper, I investigate how the EU plans to address AI in the area of non-contractual liability. I present two proposed directives and discuss how these supplement each other to create a liability regime that remains potent as the cases to which it is applied grow increasingly complicated and condi-tions harder to prove. Secondly, I address the concept of regulatory sand-boxes, its potential

With rapid increase in energy consumption of electronics used in our daily life, the building blocks — transistors — need to work in a way that has high energy efficiency and functional density to meet the demand of further scaling. III-V channel combined with vertical nanowire gate-all-around (GAA) device architecture is a promising alternative to conventional Si transistors due to its excellent
