A general method is presented for patient-specific 3-dimensional absorbed dose calculations based on quantitative SPECT activity measurements. METHODS: The computational scheme includes a method for registration of the CT image to the SPECT image and position-dependent compensation for attenuation, scatter, and collimator detector response performed as part of an iterative reconstruction method. A

Popular Abstract in Swedish Denna avhandling är resultatet av min doktorandutbildning vid Kvartärgeologiska avdelningen, Geologiska institutionen, Lunds universitet. Avhandlingen baseras på pollenanlytiska undersökningar av ett antal lokaler i södra Sverige. I denna syntes sammanfattas resultaten av undersökningarna. Introduktion och bakgrund Avsikten med avhandlingen har varit att studera etablHigh resolution pollen analysis was carried out on five peat profiles from small forest hollows at four sites in southern Sweden. The general aim was to investigate the establishment of Fagus sylvatica and Picea abies at stand-scale. The sites used for this study were all located within the area where the present distribution limits of Fagus and Picea overlap each other. The results from the diffe

The quality and quantity of UV measurements have increased greatly in the last few years. Variations among measurements from different instruments are diminishing toward the 5% level. Long-term trend detection is still a problem, with little historical data available for baseline estimations. Enhanced UV levels are clearly associated with the Antarctic springtime ozone reductions. Measurements sho

Background - Thirty patients with glioblastoma multiforme (GBM) were treated by boron neutron capture therapy (BNCT) at the Studsvik facility in Sweden, in a clinical trial exploring a procedure in which 900 mg p-boronophenylalanine (BPA) per kilo body weight was infused in 6 h. Objective - The present study was designed to assess tumor efficacy and radiation damage to the brain for the seven pati

Between 1990 and 1995 39 patients were lung transplanted at the University Hospital in Lund. This is a retrospective review of survival and lung function in these patients. There were 17 single-lung transplants (SLT), 21 double-lung transplants (DLT) and 1 heart-lung transplant (HLT). Seven patients died during the period, giving an overall survival of 82%. One-year survival according to Kaplan-Me

Body sway was investigated in 20 healthy subjects to determine whether visual input must contain motion feedback information from the surroundings in order to influence postural control. Posturography was used to record body sway under the following visual conditions: eyes open with or without a restricted visual field; eyes open in ganzfield white light; eyes open in darkness with a head-fixed vi

Abstract in Undetermined Ett hitintills outnyttjat sanktionsinstrument i den svenska konkurrenslagen är skadeståndet – en sanktion som i kartellbekämpningens ursprungsland USA intar en dominerande roll. I detta arbete har vi för avsikt att studera skadeståndets utformning och funktion i svensk och europeisk konkurrensrätt med utgångspunkt från hur det kan bidra till en effektivare kartellbekämpnin

Experiments show that nitrogen-doped carbon nanotubes subjected to the electron beam in a transmission electron microscope can easily lose dopant atoms and that overall they are less stable under electron irradiation than the pristine tubes. To understand the lower stability of nitrogen-doped nanotubes we use a density-functional-theory-based tight-binding model and simulate impacts of energetic e

This article discusses the actress and singer Zarah Leander (1907-1981), one of the most celebrated female stars in German Nazi Cinema 1936-43. She is a contradictory figure, and her star persona has always been a negotiation of antagonistic formulations, thus pointing to modes of audience identification and specatorship issues, most strikingly articulated through her immense popularity in the pos

Highly-deformed rotational bands were established in Ni-59 using the Ca-40(Si-29,2p2alpha)Ni-59 reaction. Lifetime measurements indicate that transition quadrupole moments of two of these bands decrease as they smoothly approach their maximum-spin states. The configurations of these bands as well as their band-terminating features are discussed based on configuration-dependent cranked Nilsson-Stru

The fermentation characteristics of two strains of lactic acid bacteria (LAB), Lactobacillus brevis G-77 and Pediococcus damnosus 2.6 were compared in an oat-based, nondairy milk medium (Adavena® G40). Viscosity and ropiness were the main growth parameters studied. Both strains are reported to produce an exopolysaccharide (EPS) with a -glucan structure; in addition, the L. brevis strain produces a

A multimodal approach to nondestructive seismic pavement testing is described. The presented approach is based on multichannel analysis of all types of seismic waves propagating along the surface of the pavement. The multichannel data acquisition method is replaced by multichannel simulation with one receiver. This method uses only one accelerometer-receiver and a light hammer-source, to generate
