The possibility of building compact, low-ohmic antennas suitable for mobile handsets is investigated. An F-antenna is built with a self-impedance of 10 Ω instead of the commonly used 50 Ω. Low impedance is chosen to minimize voltages in circuits prior to the antenna, in this case an adaptive matching network designed in CMOS or a similar process. To optimize this adaptive matching network, the ant
This book chapter is an attempt to discuss the tricky concept of queer and its potential meanings.
Esaias Tegnér (1782–1846), professor i grekiska vid Lunds universitet 1812–1824, därefter biskop i Växjö fram till sin död, var en av sin tids mest betydande kulturpersonligheter: en lysande diktare, en framstående talare, en dugande universitetslärare, kraftfull biskop, briljant och spirituell brevskrivare. Hans efterlämnade skrifter består av dikter och brev, samt tal hållna i olika sammanhang. The literary remains of Esaias Tegnér (1782–1846)—poet, professor, bishop—include poems, letters, and speeches. These texts are have been published in a series of scholarly editions by Tegnérsamfundet. The last volumes of the series, which will contain sermons and other ecclesiastic speeches, are due to appear in the immediate future. This was the incentive for a symposium in November 2009, held a
This paper presents a numerical investigation of the effect of different back sweep angles and exducer widths on the steady-state impeller outlet flow pattern of a centrifugal compressor with a vaneless diffuser. The investigations have been performed with commercial CFD and in-house programmed 1-D codes. CFD calculations aim to investigate how flow pattern from the impeller is quantitatively infl
Under 1100-talets sista hälft fastställdes inom kanonisk rätt principen att makarnas samtycke ensamt är tillräckligt för att skapa ett giltigt äktenskap. Varken familj eller andra auktoriteter, inte ens kyrkliga, hade laglig bestämmanderätt över två personers giftermål. Ett äktenskap kunde ingås på två sätt, antingen genom verba de presenti, löfte för det nuvarande, som med omedelbar verkan skapa
IKEA is a product developing company, known for putting packaging and logistics issues at the top of its agenda. At IKEA, the product and the packaging are developed concurrently with the aim of lowering the total cost from the supplier to the customer. During the years 2002 to 2004, a pckaging redesign project was conducted at IKEA. The purpose of the project was to redesign the packaging for an
Bioaerosols include bacterial cells and spores, viruses, pollen, fungi, algae, detritus, allergens and cell fragments. Bioaerosol particles are usually a small fraction of all aerosol particles in our surroundings, but their impact can be critical. They are a means for transmission of disease, they cause allergic reactions and they have effects on the global climate, ecology and biodiversity. This
