Purpose: The increased normal tissue tolerance for FLASH radiotherapy (FLASH-RT), as compared to conventional radiotherapy, was first observed in ultra-high dose rate electron beams. Initial clinical trials in companion animals have revealed a high risk of developing osteoradionecrosis following high-dose single-fraction electron FLASH-RT, which may be related to inhomogeneities in the dose distri

The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures. Backorder costs are traditionally assumed to be linear, whereas we consider structures that are more general functions of the customers’ time in backorder. The system studied is a two-echelon system with one central warehouse and a number of local sites,The contribution of this licentiate thesis lies in the modelling of a multi-echelon inventory system with more general backorder cost structures.

Popular Abstract in Swedish Ägglavarna, släktet Candelariella, är ett relativt litet släkte omfattande ungefär 50 kända arter i världen. Släktet är ansett som en problematisk grupp med få karaktärer som är användbara för att skilja arterna åt. Enbart ett fåtal studier har tidigare behandlat arterna och den mest omfattande är en avhandling av Rainar Hakulinen från 1954, vilken i första hand behandlThe lichen genus Candelariella comprises crustose to small squamulose members of the family Candelariaceae. The genus currently includes c. 50 species world-wide but few studies have treated the taxonomy within this group. In the present thesis the taxonomy of the genus in western North America is treated. Nine new species are proposed and in total twenty-one species are recognized from the region
Ungefär hälften av alla cancerpatienter genomgår strålbehandling, antingen som en enskild behandling eller i kombination med kirurgi och/eller medicinsk behandling. Vid strålbehandling används högenergetisk joniserande strålning för att bekämpa cancerceller. Strålningen orsakar skador på tumörcellernas DNA, men kan även skada friska celler. För att uppnå bästa möjliga behandlingseffekt med minsta FLASH radiotherapy (FLASH-RT) is a promising new approach to radiotherapy that has the potential to transform the field. By administering radiation at ultra-high dose rates (UHDR) on a millisecond timescale, FLASH-RT may increase normal tissue tolerance compared to conventional radiotherapy while maintaining the anti-tumoral effect. However, the short treatment times present unique physical and te
Allt sedan Öresundsbron öppnades år 2000 har både pendlingen över landsgränserna och integrationen i Öresundsregionen gått stadigt framåt. Det pendlas dagligen fram och tillbaka från bostaden i det ena landet till arbetet i det andra, framför allt är pendling över landsgränsen från bostaden i Sverige till arbetet i Danmark omfattande. Det finns alltid en risk för att en inkomsttagare blir dubbelThe commuting and the integration in the Öresund region have progressed ever since the bridge between Denmark and Sweden opened up for traffic in the year of 2000. Every day commuting across the border from the residence in one country to the place of work in the other country is taking place. The commuting between the residence in Sweden to the place of work in Denmark is the far most frequent.

This thesis aims at reconstructing events in the solar system, mainly collisional events in the asteroid belt, by searches for extraterrestrial minerals in Paleogene and Middle Ordovician marine sediments on Earth. Recent empirical evidence show that Earth has experienced a few brief periods during the Phanerozoic when the flux of extraterrestrial matter significantly increased. The most prominent
Popular Abstract in Swedish Enchytraeider och naidider, och deras reaktioner på miljöbetingad stress. Syftet med denna avhandling var att studera naidider och enchytraeider. Tonvikten är lagd på deras fortplantningsbeteende och hur de påverkas av miljöbetingad stress. Maskarna utsattes för stress i form av varierande kvalitet på födan, torka, och giftiga ämnen. Enchytraeider och naidider är bådaMy thesis shows that enchytraeids and naidids are sensitive to various forms of environmental stress, which in combination with the wide distribution of both families make them highly suitable for use in risk assessment and soil monitoring. Enchytraeids were subject to chemical stress under both laboratory and field conditions. In laboratory experiments enchytraeids reacted to chemical stress with
BACKGROUND: Protein S is an important regulatory protein of the coagulation cascade. The risk for venous thrombosis associated with protein S deficiency has been uncertain because all previous risk estimates used phenotypic evaluation alone, which can be ambiguous.OBJECTIVE: To quantitate the risk for thrombosis associated with a characterized protein S gene mutation that causes a Gly295-->Val sub
Popular Abstract in Swedish Datorgrafik handlar om att övertyga betraktaren. En huvuduppgift är att generera verklighetstrogna bilder utifrån tredimensionella modeller. Med hjälp av datorer simuleras hur dessa modeller interagerar med ljus. Betraktaren skall helst inte reflektera över om bilden han ser är ett fotografi eller en helt och hållet genererad bild. I denna avhandling presenteras algoritModern graphics hardware pipelines create photorealistic images with high geometric complexity in real time. The quality is constantly improving and advanced techniques from feature film visual effects, such as high dynamic range images and support for higher-order surface primitives, have recently been adopted. Visual effect techniques have large computational costs and significant memory bandwid
AbstractThe overall aims of this thesis were to use echocardiography to non-invasively, delineate early structural andfunctional changes following orthotopic heart transplantation (OHT), and to define reference values in the contextof gender and bridging with mechanical circulatory support.Several factors might affect myocardial function in OHT patients rendering the use of normal values fortranst
To resist infections, robust defense mechanisms of the airways are essential. Retinoic acid promotes differentiation and maintains the phenotypic characteristics of bronchial epithelium. In addition, it induces the expression of the antibacterial growth factor midkine (MK). In the present study, we explored the expression and antibacterial activity of MK in an airway context. MK was detected in br
Objective: This randomized methodologic study sought to test the reliability of an Internet questionnaire and investigate the differences in response rates between traditional pen-and-paper questionnaires and Internet questionnaires for measuring patient-reported outcome after total hip replacement surgery. Methods: From the Swedish Hip Arthroplasty Register, 2400 patients were chosen at random bu
Zircon crystals from a locally charnockitized Paleoproterozoic high-K metagranite from the Kerala Khondalite Belt (KKB) of southern India have been investigated by high-spatial resolution secondary ion mass spectrometry analysis of U-Th-Pb and rare earth elements (RE), together with scanning ion imaging and scanning ion tomography (depth-profiled ion imaging). The spot analyses constrain the magma
The brain lesions in spontaneously hypertensive stroke-prone rats (SHRSP) are characterised by multifocal microvascular damage, breakdown of the blood-brain barrier, massive extravasation of plasma constituents and severe brain oedema, with consequent spongy and cystic tissue destruction in the cerebral cortex and basal ganglia as well as loosening of the white matter. In this paper we analyse in
Background. Proton therapy of lung cancer holds the potential for a reduction of the volume of irradiated normal lung tissue. In this work we investigate the robustness of intensity modulated proton therapy (IMPT) plans to motion, and evaluate a geometrical tumour tracking method to compensate for tumour motion. Material and methods. Seven patients with a nine targets with 4DCT scans were selected
Chronic Lymphocytic Leukemia (CLL) is characterized by the accumulation of monoclonal CD5+ B cells with low surface immunoglobulins (IG). About 40% of CLL clones utilize quasi-identical B cell receptors, defined as stereotyped BCR. CLL-like stereotyped-IG rearrangements are present in normal B cells as a part of the public IG repertoire. In this study, we collected details on the representation an
