The thesis aims to analyse the gas turbine based energy conversion systems with the emphasis on combustion chambers. The investigation is mainly experimental at a component level. The majority of investigations concentrate on gaseous fuel firing. The influence of swirl, heat release and combustor geometry on the turbulent flows in a generic premixed gas turbine combustor, is investigated using par
Abstract Management of colorectal liver metastases (CRLM) has dramatically changed during the last decade and has now become more multimodal and aggressive, including the use of downstaging chemotherapy, portal vein embolization to increase the function of the liver remnant or both in combination. Radiofrequency ablation is also an option in CRLM, potentially combined with surgical resection. Resu
I Sverige inleddes utvecklingen mot entreprenaddriven äldreomsorg i början av 1990-talet. Sedan dess har antalet äldre som får hjälp av privata utförare blivit allt fler. Fortfarande är det dock en mindre andel av äldreomsorgen som drivs på entreprenad. Entreprenaddriften är en förhållandevis ny företeelse som fått stor massmedial uppmärksamhet genom åren. De effekter som hittills har kunnat pres

The Flinders Sensitive Line (FSL) rat is a genetic animal model of depression that displays characteristics similar to those of depressed patients including lower body weight, decreased appetite and reduced REM sleep latency. Hypothalamic neuropeptides such as orexin/hypocretin, melanin-concentrating hormone (MCH) and cocaine and amphetamine regulated transcript (CART), that are involved in the re

In pelagic ecosystems, the principal source of organic matter is via autotrophic production and the primary sink is through heterotrophic respiration. One would therefore anticipate that there is some degree of linkage between these two compartments. Recent work has shown that respiration in the light is higher than dark respiration. Consequently, many of the methods used to determine respiration
Vascular aging is described as a gradual process involving biochemical, enzymatic, and cellular changes of the vasculature and modification of the signals that modulate them. On the basis of this conception a new pathophysiological model for deeper understanding of cardiovascular risk and its treatment was introduced. The idea of early vascular aging, that is the acceleration of vascular aging see
A 12-bit 125-MHz digital-to-analog converter (DAC) for communication application is designed. It is based on current-steering segmented architecture and modified Q2 random walk switching scheme to obtain 12-bit accuracy. A new voltage swing reduced driver (VSRD) is implemented to promote the dynamic performance. The DAC uses 0.18 µm 1.8 V standard digital CMOS technology. The die area (core) is 2.
This paper is based on the findings of a research work by Abukhader and Jönson (2004a), who discuss the possibilities and limitations of the ties of postponement strategy in food supply chains. They identified the cases/examples (i.e. company cases) of application of postponement across the various categories of foods: frozen, chilled/fresh and long shelf life. The food industry nowadays is in nee
Apolipoprotein E (ApoE), a cholesterol transporter and an immunomodulator, is brain protective after experimental stroke and implicated in brain repair. Here, we study the involvement of ApoE in the restoration of brain function after experimental stroke, by using animal housing conditions that differentially improve recovery after occlusion of the middle cerebral artery occlusion (MCAO). We found
