Christopher Polhem (1661-1751), called the father of Swedish mechanics, is the most famous figure in Swedish history of technology and our nation's foremost inventor ever. Remarkably enough, a close survey in a monograph has never been written on this inventor who in many ways initiated the technical and industrial development of Sweden. In this project will Polhem for the first time get a broad a

This dissertation explores how the school subject Swedish is constructed for various groups of upper secondary school students and how the meeting between teacher and pupils is embodied in a range of Swedish subjects. The overall aim of the study is to illustrate why the teaching of Swedish in the classes under investigation takes place the way it does, as well as to discuss possible changes on a
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
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
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
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,

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
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
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
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
