Säker tillgång på vatten är en samhällsfråga som påverkar allt och alla i Sverige, skriver en rad vattenforskare och andra vattenexperter.

Events which have an adverse or positive effect on some firms can disseminate through the economy to firms which are not directly affected. By exploiting the first large sovereign bond purchase programme of the ECB, this paper investigates whether more lending to some firms spill over to firms in the surroundings of direct beneficiaries. Firms operating in the same industry and region invest less

This paper presents simulations of the radar cross section for a marine corner reflector affected by icing as it is illuminated by 3 GHz marine radar. This is compared to the radar cross section for an unaffected reflector, and the consequences for radar range are investigated. To perform the simulations, a finite element-boundary integral hybrid method is used. The simulation code is based on sev

BACKGROUND: The authors propose that for a moderate reduction of perfusion during progressive irreversible ischemia, oxygen extraction increases to maintain aerobic metabolism, and arteriojugular oxygen difference (AJDo2) increases. Because of reduced carbon dioxide washout, venoarterial difference in carbon dioxide tension (DPco2) increases, with no change in the DPco2/AJDo2 ratio. With further r

Previous research on A/B testing and continuous experimentation has mostly focused on large-scale settings with company-external customers. However, work efficiency and satisfaction for company coworkers may be highly related to internal tools and their fit-for-use. In this study, we therefore explore A/B testing for online services exclusively used by company co-workers. We A/B tested two version

Automated testing is a safeguard against software regression and provides huge benefits. However, it is yet a challenging subject. Among others, there is a risk that the test cases are too specific, thus making them inefficient. There are many forms of undesirable behaviour that are compatible with a typical program’s specification, that however, harm users. An efficient test should provide most p

This paper presents a survey that identifies lead-time consumption in the development and evolution of distributed real-time systems DRTSs. Data has been collected through questionnaires, focused interviews and non-directive interviews with senior designers. Quantitative data has been analyzed using the Analytic Hierarchical Process (AHP). A trend in the 11 organizations is that there is a statist

This paper adds a phenomenological account to the discussion on what constitutes the favorable prospects of the peer-relation in the context of self-help. By drawing on Heidegger’s lectures on St Paul’s First Thessalonians, and engaging in dialogue with a fictive case, we show that more attention needs to be given to how meaning is enacted, rather than simply adopted, in the peer-relation; that is

Nondestructive testing of composite materials is important in aerospace applications, and mm-wave imaging has been increasingly used for this purpose. Imaging is traditionally performed using Fourier methods, with inverse methods being an alternative. This communication presents a mm-wave imaging method with an inverse approach intended for nondestructive testing of singly curved composite panels

Empirical studies have shown a positive relationship between migration and fecundity, suggesting a ‘migration syndrome’ that also includes delayed reproduction and an extended reproductive lifespan. At the same time, life history theory predicts that the cost of migration should result in lower fecundity because both traits draw from a common resource. We test whether migration is associated with

Serious outcomes as stroke, arrythmia and death are relatively frequent in patients presenting with dizziness. Within 30 days almost one in five patients re-attended the ED due to dizziness and 2,8% needed ED evaluation due to a fall. Decision support tools to help identify serious conditions and predict preventable falls in ED patients with dizziness are needed.

Fibrillar protein aggregates are a hallmark of a range of human disorders, from prion diseases to dementias, but are also encountered in several functional contexts. Yet, the fundamental links between protein assembly mechanisms and their functional or pathological roles have remained elusive. Here, we analyze the aggregation kinetics of a large set of proteins that self-assemble by a nucleated-gr

The refusal to shake hands with a female reporter by a Muslim politician from the Miljöpartiet resulted in a controversy in Sweden. Together with a number of court cases, it revealed a disparity between the established judicial line and the views of the general public. The Swedish controversy received a response from Denmark, where the ruling coalition introduced new citizenship legislation with a

This book focuses on vocal expressions in the borderland between song and speech. It spans across several linguistic and musical milieus in societies where oral transmission of culture dominates. ‘Vocal expression’ is an alternative word for ‘song’ which is free from bias based on cultural and research-related traditions. The borderland between song and speech is a segment of the larger continuum

Interactions between immune cells such as T cells and antigen-presenting cells (APCs) are integral for mounting an adaptive immune response. The interaction between the T cell receptor (TCR) and the antigen-presenting major histocompatibility complex (pMHC) on a contacting T cell and APC, is widely accepted to be the key interaction. If the interaction is favourable, then T cell activation occurs.

This paper contributes to previous research on retail safety by extending the concept of safety beyond the retail store. To this end, the aim of the research is to examine the mutual relationship between retail stores and public safety in disadvantaged urban environments. The goal is to demonstrate the potential of physical retail establishments in urban environments for creating resilient and soc

Research concerning endangered languages has evolved from research on such languages, to research for their speaker communities, and more recently to research with speakers of endangered languages (Grinevald & Bert 2011:62). Such collaborations between communities and linguists are by now considered best practice and an idealized goal (Leonard & Haynes 2010) to foster more equitable relati
