Background: More than 70 million magnetic resonance (MR) examinations are produced every year. Patients and personnel are exposed to electromagnetic fields at levels that exceed those normally found in our surroundings or in industry. Three types of electromagnetic field exposure must be considered in regard to MR safety: the strong force of the static magnetic field, the time-varying gradient mag

We examine the impact of innovation disclosure through patenting on firms' cost of debt, focusing on the American Inventors Protection Act (AIPA) as an exogenous shock in innovation disclosure regulation. Post-AIPA, firms have an incentive to apply for patents only if commercial success is likely. Accordingly, we expect post-AIPA patents to be a better proxy for successful innovation activity, and

A software application combining process and input–output analysis (EAP) was used toanalyze 218 consumer products and services for environmental impacts over their lifecycle. The results are available as carbon dioxide equivalents, land use and water use perkg and per SEK. The products and services were chosen either because they are consumedby many Swedish consumers today or because they may be c

The extreme weather in terms of drought and heat, which prevailed in Northern Europe during the growing season 2018, had serious consequences for food production and farmers in southern Sweden. Many questions regarding farm production came to a head as drought struck directly against farmers land, economy and wellbeing and hence created vulnerability. This paper analyzes how farmers experienced th

Objective: To describe the demographics and clinical findings in patients with otorrhoea in Angola. Methods: A total of 411 patients with otorrhoea presenting in the ear, nose and throat clinic in Luanda and healthcare centres in other Angolan provinces underwent interview and clinical examination. We describe the demographics and clinical characteristics of the patients. Results: The majority (64

När ekonomin och sysselsättningen alltmer baseras på tjänster, möten och kreativitet istället för att många människor arbetar "fordistiskt" blir det också angeläget att lämna det modernistiska stadsbyggandet och arkitekturidealet bakom oss. Istället behövs stadsmiljöer som gynnar möten och mental stimulans.

Spatial Data Infrastructure (SDI) provides a platform for spatial data sharing and is a key for sustainable development. Developing countries, including Tanzania, are at different stages of implementing SDIs. The importance and advantage of implementation lie in the fact that considerable funds can be saved by avoiding duplication of data, and improving quality of decisions making as well as publi

We define a ray, show how to use ray intervals, and demonstrate how to specify a ray using DirectX Raytracing (DXR).

This paper explores the translation and implementation of Smart Specialisation in Wales. It finds that rather than taking a new approach to innovation policy, Welsh policy-makers are following a largely cluster-based rationale, which omits the important entrepreneurial discovery process to identify the real strengths of the region. The fresh idea presented by this paper is that a replication of pa

This paper develops a framework for analysing the role of innovation policy in regional innovation system (RIS) development. It specifically focuses on the influence of policy on a set of enabling conditions for RIS that have not been taken fully into account in previous innovation policy studies. Drawing on relevant literature on innovation systems, such as innovation policy, triple helix and pol

Recension av Volker Weidermann, München 1918. När författare och drömmare tog makten.

There is widespread agreement on the many benefits citizens gain from recreational use of local green spaces such as urban woodlands, and the importance of involving users in the development of their everyday landscapes. Despite this, the impact of userparticipation on the quality of public green spaces has not been thoroughly studied. In this PhD thesis, resident participation in public urban woo

Även om man redan under 1930- och 40 talen förstod att små vattendroppar under vissa förutsättningar kan förbättra släckeffektiviteten för vatten jämfört med större vattendroppar och slutna vattenstrålar, så var det inte förrän på 1990 talet som tekniken med fasta system med ”vattendimma” kommersialiserades. Incitamentet var i första hand det så kallade Montrealprotokollet och branden ombord på paModern, commercial water mist fire protection system technology evolved at the beginning of the 1990s due a need to replace halon fire-extinguishing systems and improve fire safety on passenger ships. This thesis documents the unknown water mist system development work by two Swedish companies during the 1970s and 1980s. It also documents the development of the first international installation rec
