BACKGROUND: The aim of this study was to investigate how much perfusion pressure an artery can tolerate without significant loss of endothelium-dependent relaxation (EDR) and vascular contractility. METHODS: The abdominal aortas of 396 Sprague-Dawley rats were used. One hundred twenty aortas were flush-perfused for 1 or 5 minutes with cold St. Thomas' Hospital cardioplegic (STHC) solution or with

The uncertainties and sources of variation in projected impacts of climate change on agriculture and terrestrial ecosystems depend not only on the emission scenarios and climate models used for projecting future climates, but also on the impact models used, and the local soil and climatic conditions of the managed or unmanaged ecosystems under study. We addressed these uncertainties by applying di

PIP: The first generation high-dose ( 80 mcg estrogen) oral contraceptives (OCs) were associated with an increased risk of deep venous thrombosis (DVT). So manufacturers removed the high-dose OCs and first replaced them with OCs with 50 mcg estrogen, resulting in a lower incidence of thromboembolic events (40 vs. 20/100,000 users). When they introduced an even lower dose OC (30 mcg estrogen), the

Popular Abstract in Swedish Är narkomaners personlighet relaterad till den drog som de valt att använda och föredrar? Detta undersöktes i en grupp om 128 tunga narkotikamissbrukare varav 37 var kvinnor och 91 män. De tre droger det gällde var heroin, som användes av 30 kvinnor och 52 män, amfetamin (7 kvinnor och 32 män) och hasch (7 män). Narkomanernas personlighet bestämdes med hjälp av två percThe topic dealt with in this thesis is whether, as Wieder and Kaplan (1969) suggest, the personality of drug addicts is related to their particular drug of choice. The subjects were 128 heavy drug addicts, 37 women and 91 men, each of them selected for the fact of there being one basic drug he/she abused. The drug of choice was either heroin (30 women, 52 men), amphetamine (7 women, 32 men) or can

Abstract Sweden has experienced a dramatic change from being a belligerent greatpower in the 17th and 18th centuries to becoming a peaceful small nation in the 19th and 20th centuries. The country has not been involved in war for over 180 years. Modern Sweden has established more or less peaceful relations with other countries. This thesis focuses on the 19th century as beeing an important period

Improved environmental consciousness and harsh legislation concerning volatile organic compounds (VOCs) during the 1980s led to an increase in the development in the field of polymer colloids. Solvent born coatings were replaced by polymer dispersions in aqueous solution, so called latex dispersions. As a consequence, numerous research programs concerning polymerization processes (e.g. emulsion po

It is expected that, in the future, gas turbines will be operated on gaseous fuels currently unutilized. The ability to predict the range of feasible fuels, and the extent to which existing turbines must be modified to accommodate these fuels, rests on the nature of these fuels in the combustion environment. Understanding the combustion behavior is aided by investigation of syngases of similar com

The present study deals with the question of cult locales in city gate contexts in Iron Age Palestine. Both archaeological and biblical sources are analysed in order to determine the presence of gate cult locales and indicate some directions of interpretation. A general framework for the archaeological identification of cult (as proposed by Colin Renfrew and others) is discussed and applied within

Spectral hole burning and photon echoes are the techniques for frequency-selective optical memories, which have the potential to increase areal data storage density by a factor 10**7. They also have the capability to perform in-memory data processing. In this thesis, several materials and techniques for optical memories in the frequency- and time domain have been investigated. In the frequency do

Popular Abstract in Swedish Vad betyder egentligen demokratisering för medborgaren i termer av möjligheter för deltagande i och inflytande över socio-politiska processer? Denna fråga står i centrum för föreliggande avhandling. Den våg av demokratiseringsprocesser som svept över utvecklingsvärlden under de senaste decennierna har medfört ökad frihet för miljontals människor och givit upphov till enThe global expansion of democratic rule in the developing world has attracted much scholarly interest. The societal implications of the democratisation process, i.e. what democratisation actually means for the citizens in terms of opportunities for participation and influence, have not received as much attention though. This study makes a contribution to redressing the imbalance. Drawing on normat

E. coli continues to be a popular host organism for production of recombinant proteins. To obtain a high volumetric productivity at the cultivation stage, it is important to achieve a high cell density and a high specific productivity per cell. In many fed-batch processes, the substrate feed rate eventually becomes limited by the oxygen transfer capacity of the bioreactor. While biomass can contin

Popular Abstract in Swedish Kultursemiotiken studerar möten mellan kulturer. Begreppen Kultur, Extra-kultur och Icke-kultur utvecklades av Tartuskolan under 1970-talet, och användes i deras studier av den ryska kulturen och dess relation till Västeuropa. Särskild vikt lades vid Peter den Stores försök att göra Ryssland mer likt Väst. Målet med denna avhandling i kultursemiotik är att vidareutvecklCultural semiotics studies encounters between cultures. Notions such as Culture, Extra-culture and Non-culture were developed in the 1970s by the Tartu school and were used in their studies of Russian culture and its relation to Western Europe, with special focus on Peter the Great's attempt to Westernize Russia in the eighteenth century. The aim of this dissertation in cultural semiotics is to fu

I uppsatsen utreds vilka praktiska problem otillbörlig webbskrapning ger upphov till i förhållande till upphovsrättighetsinnehavarens juridiska möjligheter att beivra sådant intrång. Uppsatsen syftar därtill att undersöka huruvida rättighetsinnehavare till upphovsrättsligt skyddade verk på internet innehar ett adekvat rättsskydd mot olaglig webbskrapning. Med hänsyn till syftet med uppsatsen genomThis thesis investigates the practical problems that illegal web scraping gives rise to in relation to the copyright holder's legal possibilities to prosecute such infringement. The thesis also aims to investigate whether rights holders of copyrighted works on the Internet have adequate legal protection against illegal web scraping. With respect to the purpose of the thesis, the investigation

This work has evaluated ISO 3795. It was found that ISO 3795 isn’t a suitable method to test interior materials and its use has led to a low level of fire safety in military vehicles. A different test method to be used for fire testing interior materials in military vehicles was suggested; ISO 5660 cone calorimeter. Eleven different interior materials from two military vehicles were tested in the

Abstract Moraxella catarrhalis is a new pathogenic, gram negative bacterium that is the cause of many respiratory tract infections. MID was found to be a unique protein with Ig binding capacities. Moraxella catarrhalis immunoglobulin D (IgD)-binding protein (MID) is an outer membrane protein that has specific binding affinity to the soluble cell bound human IgD. A short fragment of MID comprised

Communication in aquatic habitats commonly occurs via chemicals released from organisms. Chemical cues are used to detect prey and predators, and hence, play an important role in predator-prey interactions. Chemical cues from predators may induce morphological and behavioural responses in prey. For example, crucian carp (Carassius carassius) has demonstrated a morphologically induced defence with
