The aim of this study was to investigate potential dose reductions to the heart, left anterior descending coronary artery (LAD), and ipsilateral lung for left-sided breast cancer using visually guided deep inspiration breath-hold (DIBH) with the optical surface scanning system Catalyst™, and how these potential dosimetric benefits are affected by intrafractional motion in between breath holds. For
Background/aim: People with profound cognitive disabilities are not expected to learn powered mobility use. The Driving to Learn project focussed on what this population could achieve from practising in a joystick-operated powered wheelchair. By means of using grounded theory methodology an eight-phase process 'growing consciousness of joystick-use' was identified. In addition, a tool for assessme
Examensarbetet är utfört på och i samarbete med Imtech Ventilation i Malmö. Författarens avsikt har från början varit att skapa något som kan vara till stor nytta för företaget. Därför har examensarbetet utförts i nära samarbete med Imtech Ventilations medarbetare. Författaren har gjort en bakgrundsanalys av energikravs-läget i byggbranchen. Detta för att ta fram en validerad problemformulering ocThis master thesis is performed on and in cooperation with Imtech ventilation in Malmö. The author's intention was from the beginning to create something that can be of great benefit to the company. The master thesis has been carried out in close cooperation with the employees of Imtech Ventilation. The author has done a background analysis of the current excising energy regulations. This was
Pufendorfinstitutet är ett tvärvetenskapligt institut med syfte att stimulera till samarbete mellan forskare från olika discipliner inom Lunds universitet. I "Teman" och" Advanced Study Groups" ges forskare från alla universitetets fakulteter möjlighet att tillsammans utforska vetenskapliga problem .The Pufendorf Institute for Advanced Studies is an interdisciplinary institute with the aim to stimulate collaboration between researchers from different disciplines within Lund University. In "Themes" and "Advanced Study Groups", researchers from all faculties of the university are given the opportunity to jointly explore scientific issues.
The simultaneous adsorption of copper (Cu), cadmium (Cd), nickel (Ni), and lead (Pb) ions from spiked deionized water and spiked leachate onto natural materials (peat A and B), by-product or waste materials (carbon-containing ash, paper pellets, pine bark, and semi-coke), and synthetic materials (based on urea-formaldehyde resins, called blue and red adsorbents) or mixtures thereof was investigate
The structural properties of a system of ionic microgels under the influence of an alternating electric field are investigated both theoretically and experimentally. This combined investigation aims to shed light on the structural transitions that can be induced by changing either the driving frequency or the strength of the applied field, which range from string-like formation along the field to
Novel experimental data, obtained recently using advanced multi-scale experiments, have been used to develop a micro-mechanically motivated constitutive model for amorphous glassy polymers. Taking advantage of the experiments, the model makes use of a microstructural deformation gradient to incorporate the experimentally obtained deformation of the microstructure, as well as its evolving orientati
In the last decades intra-industry trade (IIT) got a lot of attention in economic research. In 1975 Grubel & Lloyd presented a way of measuring IIT, this method is used even today. Later researchers found out that IIT can be disentangled into vertical and horizontal IIT. To calculate vertical and horizontal IIT unit-values are used. In this paper I want to test different ways of measuring, IIT
Density functional theory was employed to investigate the adsorption site and hyperfine interactions of nitric oxide adsorbed in Na-LTA (previous name NaA) zeolite. Three different cluster models of increasing complexity were used to represent the zeolite network: (1) a six-membered ring terminated by hydrogen atoms with one sodium ion above the ring, (2) as model 1 with the addition of three sodi
As road networks are becoming increasingly utilised, it is increasingly important to be able to accurately predict travel times for disseminating information among road users and to support traffic management decisions and planning. Over the past few years, a new way of making such predictions utilising the space-time autoregressive integrated moving average (STARIMA) model has been introduced. Th
We present a comparison of experimentally and theoretically determined osmotic pressures for various colloidal dispersions. Experimental data is collected from several different silica and polystyrene dispersions. The theoretical pressure determinations are based on the primitive model combined with the cell model, and the physical quantities are calculated exactly using Monte Carlo simulations in
In Space Division Multiple Access (SDMA) systems, users are separated based on their positions. The base-station (BS) signals typically reach the users through multipath clusters. The goal of this work is to find the probability that a randomly selected user will receive the signal from the BS via at least one nonshared (by any other user) multipath cluster. This probability, referred to as PSucce
Purpose. This article describes an ex vivo method to recondition and transplant rejected donor lungs. Description. A 19-year-old man was brain dead after a traffic accident. A roentgenogram showed bilateral lung contusion. He had ongoing intratracheal bleeding. After optimizing ventilator treatment and suctioning the airways, PaO2 was 9 kPa (67.5 mm Hg) on FiO(2) = 0.7. The lungs were rejected by
A general model for through drying of tissue was developed based on the equations of continuity in combination with correlations for heat and mass transfer. The model incorporates different geometric descriptions together with corresponding heat and mass transfer correlations for flow through cylindrical conduits and flow through packed beds of cylindrical fibers. At low intensities, i.e., at low
The knowledge about the hydraulic conductivity of the subsurface is crucial to know as it is a main parameter for groundwater flow characterization within an aquifer. The geophysical method time-domain Induced Polarisation has been shown to be useful for estimating the hydraulic conductivity. By using a new inversion approach, where we directly invert for hydraulic properties as inversion paramete
The FinEstBeaMS beamline is under construction at the 1.5 GeV storage ring of the MAX IV Laboratory at Lund, Sweden. It has been designed to cover an unusually wide energy range from ultraviolet (4.3 eV) to soft X-rays (1000 eV) but experiments will also be possible at the Mg and Al Kα energies. Instead of having two different insertion devices and optical schemes for low and high photon energy re
Aeolian dunes, coversands, glacifluvial deltas and paraglacial mass-movement deposits in Bonäsheden and Skattungheden in Dalarna, central Sweden were dated by optically stimulated luminescence (OSL) on quartz. The OSL ages confirm that the majority of the dunes started forming directly after deglaciation, as suggested by previous investigators. Dune formation seems to have lasted at least 1500 yea
