Safety, perceived and real, is essential for the attractiveness of urban environments (Avraham & Ketter, 2008, Coaffee & van Ham, 2008, Avraham, 2009). A high degree of perceived safety of a place plays a large role in attracting retail businesses, personnel, and customers. However, perceived safety is not an isolated issue, but related to many aspects, such as the planning of city space,
The mismatch of the coefficients of thermal expansion between cathode and electrolyte is one of the thorniest problems for high-performance proton-conducting solid oxide fuel cells (H–SOFCs). Here one strategy is applied by introducing the negative thermal expansion component, Y2Mo3O12 (YMO), on Ba0.5Sr0.5Co0.8Fe0.2O3-δ (BSCF) cathode to overcome this difficulty. As a result, not only the electrol
1. We manipulated the size hierarchy in broods of marsh tits (Parus palustris L.) by simulating hatching asynchrony to study how nestlings of different competitive ability, allocate their share of parental feedings to different growth strategies. 2. The mean rate of mass increase and the mass when the growth curve had reached an asymptote increased with the predicted competitive ability of nestlin
Popular Abstract in Swedish I dagens nya cellulära kommunikationssystem betraktas användandet av multipla mottagarantenner i kompakta användarterminaler som en nödvändighet för att kunna utnyttja fördelarna med diversitet och MIMO (Multiple Input Multiple Output) teknik och därmed uppnå god celltäckning och hög dataöverföringshastighet. Den senaste utbyggnaden av det cellulära kommunikationssystemCo-band multiple-antenna implementation in compact user terminals is necessary for harvesting the full potential of diversity and multiple-input multiple-output (MIMO) technology in cellular communication systems. The recent worldwide deployment of Long Term Evolution (LTE), which requires the use of MIMO technology in the downlink, adds to the urgency of achieving both practical and optimal multi
Popular Abstract in Swedish Svensk Kärnbränslehantering AB, SKB, har i uppdrag att ta hand om allt radioaktivt avfall från de svenska kärnkraftverken. En av förutsättningarna för att SKB ska få tillstånd att uppföra inkapslings- och slutförvars¬anläggningarna är att metod och teknik för att försluta kapslarna finns. De förslutna kapslarna ska uppfylla de krav på långsiktig säkerhet som SKB, myndigThis thesis presents the development to reliably seal 50 mm thick copper canisters containing the Swedish nuclear waste using friction stir welding. To avoid defects and welding tool fractures, it is important to control the tool temperature within a process window of approximately 790 to 910°C. The welding procedure requires variable power input throughout the 45 minute long weld cycle to keep th
Adaptor proteins assist proteases in degrading specific proteins under appropriate conditions. The adaptor protein YjbH promotes the degradation of an important global transcriptional regulator Spx, which controls the expression of hundreds of genes and operons in response to thiol-specific oxidative stress in Bacillus subtilis. Under normal growth conditions, the transcription factor is bound to
We examine pre-service teachers’ theoretical learning during one five-week training module, and their educators’ learning about better lecture design to foster student learning. The study is iterative: interventions (one per group) were implemented sequentially in student groups A–C, the results of the previous intervention serving as the baseline for the design developed for the next. These learn
Heavy metal (HM)-polluted soil is a serious concern, especially as brackish water is widely used for irrigation purposes in water-scarce countries. In this study, the HYDRUS-2D model was used to simulate HM (copper (Cu), lead (Pb), and zinc (Zn)) transport through agricultural land cultivated with potato crops under surface drip irrigation to explore the potential groundwater contamination risk. T
Structural brain MRI has proven invaluable in understanding movement disorder pathophysiology. However, most work has focused on grey/white matter volumetric (macrostructural) and white matter microstructural effects, limiting understanding of frequently implicated grey matter microstructural differences. Using ultra-strong spherical tensor encoding diffusion-weighted MRI, a persistent MRI signal
Objective: The mechanisms and metabolomic profile underlying early vascular ageing have not been explored in the general population. We aimed to investigate the plasma metabolomic profile in aortic stiffness (vascular ageing) and associated risk of incident cardiovascular disease and mortality in the general population.Design and method: We analysed 108 metabolites in plasma of 5172 individuals fr
A method for generating motion-corrected medical images includes obtaining, via a processor, k-space data of a region of interest acquired by a magnetic resonance imaging system utilizing a 3D radial pulse sequence with ZTE acquisition including optional magnetization preparation pulses. The method also includes sampling, via the processor, the k-space data to obtain a plurality of interleaved k-s
This chapter discusses Ilia Repin’s court commission, Reception of Volost Elders by Alexander III in the Courtyard of the Petrovsky Palace in Moscow (1886). It argues that the painting reflected marginalizing discourses on the non-Russian minorities dominant at the outset of Alexander III’s rule. Repin employed a differentiating approach to rendering ethnically and religiously diverse representati
In this paper I study how 1500 returned Swedish-Americans acted after their return to a mainly rural area of southern Sweden. The rural society in which the returnees grew up before immigrating to America was still largely a self-sustaining society albeit with a slowly expanding market economy. Most of the returnees came from a poorer background but quite a few of them experienced upward social mo
