EPR spectroscopy has been employed to determine the nature of vanadium (+4) species in the TiO2(B)-supported vanadia catalysts. IR and EPR studies show that multiple vanadia species are observed as a function of loading. At coverages greater than 3.5 theoretical layers, the EPR signal is reminiscent of bulk V205. At lower coverages, a different magnetic species dominates the resonance and may be a

Different methods to separate quark jets from gluon jets have been investigated and tested on data from the DELPHI experiment. A test sample of gluon jets was selected from $bar{b}g$ threejet events where the two b-jets had been identified using a lifetime tag and a quark jet sample was obtained from $qar{q}gamma$ events where the photon was required to have a high energy and to be well separated

In this thesis, the fluid dynamic properties of the conventional Rushton turbine and another impeller type, the Scaba Radial flow Gas dispersing Turbine (with six concave blades) are compared. For comparison, point-wise velocity measurements were made in the discharge of the two turbine types using Hot-Wire Anemometry in constant temperature mode (CTA) with a split film probe. For the time-average

The Nordic countries have often been seen as “fore-runners” of energy efficiency in buildings in terms of both 1) the implementation of policy instruments and 2) the evaluation of actual effects. Since the 1970s, the Nordic countries have introduced a range of policy instruments for energy conservation in buildings. Interestingly, there are contrasting policy “styles” and experiences across the No

This work focuses on measurement principles based on ultrasound for applications in industrial automation. The measurements made are of geometric nature. The methods used are when possible based on experience and/or inspiration from the study of bats. A platform for ultrasonic measurements, that allows a VME-based host computer to transmit and receive signals, with a considerable flexibility has b

Popular Abstract in Swedish Cancer i tjock- och ändtarmen är idag den tredje vanligaste formen av till döden ledande cancer i världen. Den är vanligast i de högindustrialise-rade delarna av världen: Europa, Nord-Amerika och Australien. Prognosen för den enskilde patienten är helt beroende på cancerns utbredning vid diagnostillfället. Cancerns utbredning bedöms idag enligt olika indelningsprincipeAim of the study Today´s methods for the staging of rectal carcinoma: ultrasonography with transrectal probe, CT, MRI or MRI with a rectal coil, all have limitations. The aim was therefore to develop a new, double-contrast MRI method for evaluation of rectal carcinoma. The idea was that a rectally applied contrast medium causing distension and signal void of the rectal lumen and an intravenous inj

Critical infrastructures provide society with services that are essential for its functioning and extensive disruptions of these give rise to large societal consequences. Vulnerability analysis gives important decision information concerning improving their ability to withstand strains. To analyze vulnerabilities in infrastructures models for estimating consequences due to failures are needed. Con

Laparoscopic surgery was introduced to minimize patient trauma. However, fatal technique specific complications, due to major vascular or visceral injury, were at times seen related to blind abdominal access using the Veress technique. A modified open access technique was developed and evaluated in 100 patients and found to be fast and easy to learn with few associated complications. This open te
