Investigation of the fetal heart circulation in an animal model using contrast enhanced ultrasound

To assess the distribution of blood from the umbilical vein (UMV), inferior vena cava (IVC) and superior vena cava (SVC) to either side of the fetal lamb heart by using ultrasound enhanced contrast agent imaging. By injection of ultrasound contrast agents (UCA) in UMV, IVC or SVC, the blood from these vessels was tracked, as it then was highly echogenic. By evaluating the image intensity within th

Swedish Butterfly Monitoring Scheme, annual report for 2011

This is the second annual report for the Swedish Butterfly Monitoring Scheme, a national monitoring programme coordinated by Lund University for the Swedish Environmental Protection Agency since 2010. The programme is a partnership between the Entomological Society of Sweden, the Swedish Environmental Protection Agency, Lund University, the Swedish University of Agricultural Sciences and the Swedi

Particle Deposition Studies in a Laminar Wall Jet - The Hydrodynamic Influence on the Kinetics of Colloidal Deposition

Popular Abstract in Swedish Inom forskningen kring rengöring och processhygien är det viktigt att förstå de bakomliggande mekanismerna för depositionen av partiklar och makromolekyler på ytor. Depositionsprocessen kan beskrivas som transporten av partiklar till ytan och den påföljande adhesionen. Om de hydrodynamiska krafterna är tillräckligt starka kan partiklarna åter transporteras bort från ytaIn the research area of cleaning and process hygiene it is important to understand the underlying mechanisms behind the deposition of particles and macromolecules onto surfaces. The deposition process is described as the transport of particles to the surface followed by attachment. If the hydrodynamic forces are strong enough, the particles can be re-entrained. In this work particle deposition wa

On LFSR based Stream Ciphers - analysis and design

Popular Abstract in Swedish Den här avhandlingen handlar om kryptering, strömchiffer, metoder för att analysera (knäcka) och konstruera bättre chiffer. Det finns flera olika metoder för att hemliggöra meddelanden. Det klassiska sättet är att två personer som vill kommunicera delar en hemlig nyckel som används för att både kryptera och dekryptera meddelanden. Denna metod kallas symmetrisk krypteriStream ciphers are cryptographic primitives used to ensure privacy in digital communication. In this thesis we focus on stream ciphers built using Linear Feedback Shift Registers (LFSRs). Several different stream ciphers are analysed and new attacks are presented. In addition, two new stream ciphers are presented, both based on the same design. The first attack is performed on SOBER-t16 and SOBER

Ecology of red admiral migration

The red admiral (Vanessa atalanta) is a migratory butterfly that can be found in North America, North Africa, Europe and some parts of Asia. In Europe the main part of the population spend winter in the Mediterranean region and the following spring leave this area to breed further to the north. At least one new generation is then produced in the summer region before they return to the south again

Approximating Decoding Thresholds of Punctured LDPC Code Ensembles on the AWGN Channel

In this paper, we provide an efficient way to predict iterative belief propagation (BP) decoding thresholds of randomly punctured low-density parity-check (LDPC) code ensembles on the binary-input additive white Gaussian noise channel (AWGNC), given only the BP threshold of the mother code ensemble on the binary erasure channel (BEC) and the code design rate. We show that the predictions are accur
