Altered vascular responses in experimental congestive heart failure

Popular Abstract in Swedish Hjärtsvikt är ett sjukdomstillstånd som blir allt vanligare i vårt samhälle i takt med att människor blir äldre och att man idag räddar allt fler människor till livet efter hjärtinfarkt. Som namnet antyder sviktar hjärtat, det kan inte pumpa ut den mängd blod som krävs för att tillgodose kroppens behov av syre och näringsämnen. Sjukdomen indelas i olika svårighetsgraderCongestive heart failure is accompanied with increased circulatory levels of several vasoregulatory neurotransmitters and hormones which affect the outcome of this disease. In this thesis the blood levels of several vasoactive peptides in humans with congestive heart failure and their effects on the vasculature by the use of an animal model of heart failure were studied. Patients with congestive

Performance Analysis of a Countercurrent Flow Heat Exchanger Placed on the Truck Compartment Roof

Due to the increasing power requirement and the limited available space in vehicles, placing the heat exchanger at the roof or the underbody of vehicles might increase the possibility to handle the cooling requirement. A new configuration of the heat exchanger has to be developed to accommodate with the position change. In this paper, a countercurrent heat exchanger is developed for position on th

Make-or-buy decisions and the manipulability of performance measures

Abstract in UndeterminedThe make-or-buy decision is analyzed in a simple framework combining contractual incompleteness with the existence of an imperfect but contractible performance measure. Contractual incompleteness gives rise to two regimes, identified with make and buy. The performance measure on which comprehensive contracts can be written is imperfect in the sense of being subject to manip

Perspectives on Lattice Boltzmann Modeling of Transport Processes with Electrochemical Reactions in SOFCs

Lattice Boltzmann method (LBM) is alternative computational method to the traditional computational fluid dynamic (CFD) methods. LBM has the ability to with straightforward computational procedure to handle the detail activity at microscale well for simulation of different transport processes. In this study the focus is on the effects of electrochemical reactions and transport processes in an anod

Targeted Killing: A Legal and Political History

Looking beyond the current debate’s preoccupation with the situations of insecurity of the second intifada and 9/11, this book reveals how targeted killing is intimately embedded in both Israeli and US statecraft and in the problematic relation of sovereign authority and lawful violence underpinning the modern state system. The book details the legal and political issues raised in targeted killing

Formation of mesoporous SBA-15 from a colloidal perspective

The formation of the hexagonal ordered mesoporous SBA-15 material has been invetsigated. The evolution from free spherical micelles into an ordered material was studied with time-resolved in-situ SAXS, USAXS and SANS measurements. Both the mesoscopic region and the colloidal region were monitored. Temperature, precursor and salt additions have been varied. From the time-resolved measurements the e

Metastability of persistent currents in trapped gases of atoms

We examine the conditions that give rise to metastable, persistent currents in a trapped Bose-Einstein condensate. A necessary condition for the stability of persistent currents is that the trapping potential is not a monotonically increasing function of the distance from the trap center. Persistent currents also require that the interatomic interactions are sufficiently strong and repulsive. Fina
