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
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
Popular Abstract in Swedish En emulsion är en blandning av två vätskor som ej löser sig i varandra. Oftast så är det små oljedroppar som omges av vatten, alltså en olja-i-vatten emulsion. För att få en stabil emulsion måste man även tillsätta en emulgator. En emulgator har en del som trivs i olja, en hydrofob del, och en del som trivs i vatten, en hydrofil del. Den kan alltså sätta sig på oljedropEmulsions find a variety of applications in for example food, cosmetics and pharmaceutical preparations. In order to obtain emulsions with desired properties it is important to understand how different factors, such as the properties of the emulsifier and the emulsification procedure, impact the final emulsion properties. The studies performed in relation to this thesis have mainly been focused
This paper examines the major trends unravelling the long-term gender division of family support and care structure that reached its peak in the middle of the twentieth century, often called the “worker-carer” or the “separate spheres” model. The unraveling of the “separate spheres” began with the increase in the labor force participation of married women and continues with the increase in men’s i
