A Virtual Reality experiment on the design of flashing lights at emergency exit portals for road tunnel evacuations

A virtual reality (VR) experiment with 96 participants was carried out in a Cave Automatic Virtual Environment (CAVE) laboratory at Lund University to provide recommendations on the design of flashing lights at emergency exit portals for road tunnel emergency evacuation. A set of variables were investigated, namely 1) Colour of flashing lights, 2) Flashing rate, 3) The type of light source, 4) The

It takes two to Tango!

If you want to become “teacher of the year“ - how do you do? The easy answer is to get yourself a group of “students of the year“! But, if you don't have that – how do you help your average students to become “students of the year“? In order to do that we must be active and take pedagogical leadership. In this roundtable we want to discuss questions like: • How can we stimulate the students’ inter

CMOS antenna tuning unit for 2.4 GHz ISM band

Antenna matching is improved with adaptive 0.35 μm CMOS circuits based on switched shunt capacitors arranged in capacitor banks and external series inductors. The simulated circuits are optimized for the ISM 2.4 GHz band. The circuits provide a VSWR ⩽ 2 match for every impedance with VSWR ⩽ 5. There is a 1 dB power loss for a perfect 50 Ω → 50 Ω transformation, a break-even point at VSWR = 1.5, an

Value uncertainty and value instability in decision-making

The purpose of this paper is to clarify the role of value uncertainty and value instability in decision-making that concerns morally controversial issues. Value uncertainty and value instability are distinguished from moral uncertainty, and several types of value uncertainty and value instability are defined and discussed. The relations between value uncertainty and value instability are explored,

Lactic acid production: extractive fermentation in aqueous two-phase systems

There is an increased interest in the microbial production of lactic acid as a raw material for the synthesis of lactic acid polymers as biodegradable plastics. However, two factors limit the economical competitiveness of lactic acid production by microorganisms: lactic acid inhibition, which decreases both fermentation rate and the maximum lactic acid concentration, and the efficiency in the reco

Characterisation of the microbial community in indoor environments: Critical evaluation of sample storage conditions

Assessment of indoor air quality in terms of microbial flora is important since inhalation of air-borne microorganisms has been associated e.g. with asthma and allergy. We focus on certain unique microbial markers: muramic acid, marker of bacterial peptidoglycan/biomass; 3-hydroxy fatty acids with 10-18 carbon chains, markers of lipopolysaccharide (LPS, endotoxin) of Gram-negative bacteria; and er

Mutation screening of NOS1AP gene in a large sample of psychiatric patients and controls

BACKGROUND: The gene encoding carboxyl-terminal PDZ ligand of neuronal nitric oxide synthase (NOS1AP) is located on chromosome 1q23.3, a candidate region for schizophrenia, autism spectrum disorders (ASD) and obsessive-compulsive disorder (OCD). Previous genetic and functional studies explored the role of NOS1AP in these psychiatric conditions, but only a limited number explored the sequence varia

Tea-party-diplomati. Kvinnors strävan att motverka våld i Palestina 1920-1948.

The chapter focuses on European women who visited Jerusalem during the British Mandate period trying to prevent violence and build peace in civil society in times of violent conflict. Some of them were connected to the Anglican missionary schools, others were occasional visitors sent out by international peace organisations. Especially the informal role of women for peace building is emphasised. I

Introducing the Berkeley Method of Entrepreneurship - a game-based teaching approach

Entrepreneurship matters. In modern open economies, entrepreneurship is one of the key aspects for economic growth and is often thought of as the act of commercializing on an innovation. Teaching and learning entrepreneurship is therefore of importance and schools, colleges and universities can play an important role by including entrepreneurship and innovation in their curricula. Governments and

The Power of Maps. The Region as a Societal Vision in the Age of the Öresund Bridge

The dissertation seeks to problematize the public debate which in recent years has made many people interested in and committed to the region. The empirical basis of the study is some of the regions of southern Sweden which have served as an important platform in the last thirty or forty years when the political and economic establishment has acted and argued in various contexts. The fundamental q
