Popular Abstract in Swedish Malaria är en allvarlig febersjukdom som varje år drabbar nästan 250 miljoner människor. Sjukdomen är mycket utbredd inom tropiska och subtropiska delar av världen och världshälsoorganisationen (WHO) har beräknat att strax under en miljon människor, majoriteten av dem barn, dör av malaria varje år. Malaria har följt människan under mycket lång tid och var länge vanlig iMalaria is a serious disease that causes around 800 000 deaths per year. Current malaria control efforts are hampered by the widespread resistance to common antimalarial drugs, such as the 4-aminoquinoline derivative called chloroquine. Previous research has shown that specific modifications of chloroquine, including inclusion of organometallic fragments into the organic framework, can result in c

Popular Abstract in Swedish I Tallsten barnomsorgs- och skolenhet införde man 1996, som del i en omorganisation av verksamheten, ett nytt tanke- och arbetssätt utifrån en kommunikativ pedagogik. Tre mindre organisatoriska enheter, som var mer eller mindre slutna i förhållande till varandra, slogs samman till en enhet. Ett primärt syfte i sammanhanget var att skapa en helhetssyn på barnet från 1?18This thesis focuses on the pedagogue as a social being and how she or he experiences the social life in preschools and schools in Tallsten. In 1996, the child-care and education authorities in Tallsten introduced a new manner of thinking and working based on the communicative pedagogy. The idea of communicative pedagogy was origanlly put forth by the Danish teacher Lars Rokkjaer. One of the goals

This thesis presents two prime contributions. First, digital filters for both intermediate and base band filtering for mobile communication are presented. Second, a local clock for on-chip clock generation is introduced. The intermediate frequency filter is a digital alternative to today's analog filters. It is a narrow band filter designed for the American digital mobile telephone system accordin

Vad gör en skolledare framgångsrik? Och vad gör en framgångsrik skolledare? I denna artikel presenteras några resultat från forskningsprojektet Framgångsrikt skolledarskap i olika skolkulturer, vilka delvis utgör svar på frågorna. Resultaten härrör från intervjuer, enkäter, observationer och elevuppsatser och utgörs av olika skolaktörers kriterier för bedömning av skolledares framgång. I likhet me

This paper deals with line-drawings, obtained from images of polyhedral objects after edge detection. Such images are used e.g. for recognition and reconstruction. In the presence of noise, in general they do not obey the geometric conditions imposed by the projective imaging process. Under various optimality conditions, algorithms are presented for the correction of such line-drawings, disturbed

Historia förmedlas ofta på ett inflytelserikt sätt på film. I "World War II at 24 Frames a Second" jämförs filmiska representationer av andra världskriget i Danmark, Norge och Sverige med fokus på den senaste tioårsperioden.

One of the most common Neolithic tool types in Scandinavia which is available to us for study today is the axe. Judging by the thousands of such axes found in museum collections, this tool was an important part of Neolithic man's toolkit. While most of the axes which are considered primarily work axes (as opposed to the more ceremonial so-called battle axes) are made of flint, other, non-flint mat

Popular Abstract in Swedish Blödande åderbråck i matstrupen - en jämförande studie mellan kirurgisk shunt och lokal behandling Patienter med skrumplever riskerar många komplikationer. Den mest fruktade är blödning från oesofagusvaricer, dvs åderbråck i matstrupen. Fyrtio procent av patienterna avlider om de inte får behandling. Anledningen till att patienter med skrumplever (cirros) utvecklar oesThis thesis is aimed at evaluating the clinical results of two treatments in patients with bleeding oesophageal varices; the mesocaval interposition shunt (MI shunt) and repeated endoscopic sclerotherapy (ST). 24 patients were randomised to MI shunt and 21 patients to the ST group (mean age 51.6?9.2 and 53.6?10.5 years). Complications include shunt occlusion in 4 %, oesophagitis in 33 % and oesoph

In this paper we study the infinitesimal-time case of the so called multilinear constraints that exist for each subsequence in a sequence of images. These constraints link the infinitesimal motion of the image points with the infinitesimal viewer motion. The analysis is done both for calibrated and uncalibrated cameras. Two simplifications are also presented for the uncalibrated camera case. One s

Popular Abstract in Swedish Cellulära mekanismer vid ischemisk tolerans Stroke, hjärntrauma, hjärnblödning och övergående hjärtstillestånd, leder till minskat blodflöde till hjärnan (ischemi) och orsakar hjärnskador. Mot denna skadeutveckling finns ännu inte något medel för kliniskt bruk. I djurexperimentella ischemimodeller har man kunnat skydda hjärnan mot ischemiska skador genom att utsätta hjäA brief period of sublethal ischemia in the brain induces resistance to a subsequent, otherwise lethal ischemic insult. This phenomenon is known as ischemic tolerance or preconditioning. A model of ischemic preconditioning in the rat brain using the two-vessel occlusion model of global cerebral ischemia was established. Using this model we have demonstrated that ischemic preconditioning protects t

Urban Transport Development is a contribution to the ongoing global discussion on the future of urban transport. The main themes are how to cope with the complexity of urban transport development and the process of change including its determining factors. The role of leadership in the development process is the key issue. Main areas of discussion are the historical background, the diversity and c

Introduction of roughness by ribs in flow passages is a popular method of enhancing heat transfer in the cooling passages, e.g., of turbine blades and combustors. It is essential to accurately predict the enhancement of heat transfer generated by the ribs to ensure good design decisions. In most of the studies square ribs have been considered, but in practice such ribs may appear rounded due to im

Popular Abstract in Swedish Avhandlingen är en studie av kvinnors brevskrivning i Sverige under 1700-talet. Breven är skrivna av ett antal kvinnor från de högre samhällsskikten (adel och borgerskap) under 1780- och 1790-talen. Flertalet av breven är skrivna på svenska, men några också på franska. Huvudsyftet med avhandlingen är att undersöka relationen mellan idén om att kvinnor skrev annorlunda, This dissertation is a study of women's letter-writing in eighteenth-century Sweden. The letters are written by a number of women from the uppper classes (nobility and bourgeoisie) during the last two decades of the eighteenth century. The majority of the letters are written in Swedish, some however in French. The main aim is to examine the relationship between the idea of women as a special kind
