Specimens of large fungi (mushrooms) were screened for mutagenic activity by the Salmonella/microsome assay, with strains TA98, TA2637 and TA100. Out of 48 species tested, 37 exhibited a significant but for the most part weak activity. The activity observed in the presence of S9 mix was typically between 0 and 50% of that without, and in no case was the activity increased in the presence of micros
Invasive plants cause substantial economic and environmental damage throughout the world. However, eradication of most invasive species is impossible and, in some cases, undesirable. An alternative is to slow the spread of an invasive species, which can delay impacts or reduce their extent. We identify three main areas where models are used extensively in the study of plant spread and its manageme
Background: Due to a lack of coordination of care flow events and uncertain capacity coordination, long patient waiting times for patients arise, entailing a medical risk and contributing towards capacity being utilized less effectively. Healthcare services are often said to be crucial to coordinate in order to create equally good availability for care-seekers. Could healthcare matching become the
PURPOSE: About 60% of ovarian cancers are diagnosed at late stage, when 5-year survival is less than 30% in contrast to 90% for local disease. This has prompted search for early detection biomarkers. For initial testing, specimens taken months or years before ovarian cancer diagnosis are the best source of information to evaluate early detection biomarkers. Here we evaluate the most promising ovar
This paper examines corporate angels, small businesses that provide equity capital directly to unquoted ventures and become minority shareholders. Corporate angels have been largely ignored in entrepreneurial finance research. This novel study examines corporate angels' investment practices, goals and challenges by means of a combination of qualitative cases and a survey of 87 corporate angels. Fr
A persistent anthropocentric school of thought prevents comparative cognition from truly joining the evolutionary sciences, which often view “cognition” as an alien subject to the study of life. In this article, I argue that cognition is indeed inherent to all life and that we could study the evolution of cognitive skills like any other species-specific trait if we stop elevating convergence over
Ribosomes trapped on mRNAs during protein synthesis need to be rescued for the cell to survive. The most ubiquitous bacterial ribosome rescue pathway is trans-translation mediated by tmRNA and SmpB. Genetic inactivation of trans-translation can be lethal, unless ribosomes are rescued by ArfA or ArfB alternative rescue factors or the ribosome-associated quality control (RQC) system, which in Bacill
Digital healthcare services and digital health information, here called eHealth services, have the potential to reach people with diverse needs as both a complement to and a substitution for traditional healthcare. The access to and use of digital health information and digital healthcare services that are accessible and usable for people with impairments is a complex phenomenon.This potential is
BACKGROUND: Coronary atherosclerosis detected by imaging is a marker of elevated cardiovascular risk. However, imaging involves large resources and exposure to radiation. The aim was, therefore, to test whether nonimaging data, specifically data that can be self-reported, could be used to identify individuals with moderate to severe coronary atherosclerosis.METHODS AND RESULTS: We used data from t
Contemporary society operates beyond safe boundaries of the Earth system. Returning to a safe operating space for humanity within Earth system boundaries is a question of justice. The relevance of the economy—and thus of business—for bringing society back to a safe and just operating space highlights the importance of business ethics research for understanding the role of business in Earth system
Livscykelanalys (LCA) används för att utvärdera den potentiella miljöpåverkan av olika processer och tjänster, bland annat inom bygg- och fastighetssektorerna. Denna studie jämför tre LCA-verktyg som är speciellt utvecklade för användning inom bygg- och fastighetssektorn mot ett fjärde som är ett allmänt LCA-verktyg. En LCA görs för en fallstudie av ett flerfamiljshus där ett ventilationssystem meLife cycle assessment (LCA) is used to evaluate the potential environmental impact of different processes and services, including in the construction and real estate sectors. This study compares three LCA tools that have been specifically developed for use in the construction and real estate sectors with a fourth that is a general LCA tool. An LCA is performed for a case study of a multi-family bu
Climate change poses an existential threat to humanity. It is now indisputable that the primary cause of this threat is human activity resulting in high greenhouse gas (GHG) emissions, which began during the Industrial Revolution and have continued to rapidly accelerate. The first warnings of impending and irreversible climate change were sounded decades ago, when governmental and intergovernmenta
In this blog, Jason Tucker, Associate Senior Lecturer at Malmö University, challenges the ways in which the international community programmatically engages with stateless refugees. Drawing on his research investigating the governance of stateless refugees, Jason argues that the statelessness of stateless refugees is systematically and chronically under-valued, sometimes with devastating consequen
On October 9, 2023, Harvard University Professor Claudia Goldin received the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel, a landmark achievement that not only celebrates her outstanding contributions but also highlights the profound impact an economist can have on society.
Quality requirements complement functional requirements with information on the target quality levels of software functions or emergent system quality aspects. In release planning the allocation of development effort in further investments into product enhancements, new or enhanced functions are competing with quality improvements for limited resources. When setting balanced quality targets for de

This thesis deals with tools for operational improvement of supply chain performance. The work was aimed at providing knowledge for supply chain developers and practitioners, and identifying and developing tools for improved performance in a supply chain. The investigation was part of a project financed by the European Commission called "Industrial Supply Chain Optimizer" (ISCO). The thesis consis
