Monte Carlo-simuleringar har fått en ökad betydelse som forskningsverktyg inom nuklearmedicinsk bildgivning eftersom man på ett mycket kontrollerat sätt kan studera nästan vad man vill. I denna studie har datorsimuleringar av ett PET-system gjorts med ett program som heter GATE. PET (Positron Emission Tomography) är en nuklearmedicinsk bildgivningsteknik som används mer och mer inom sjukvården sIntroduction: Monte Carlo simulation is a powerful tool in research in the field of nuclear medicine imaging and there is a wide area of applications. The purpose of this work was (1) to understand the basics of the Monte Carlo simulation software Geant4 Application for Tomographic Emission (GATE); (2) to create a model of Philips Gemini TF PET/CT system; (3) to run a number of simulations to comp
Tetra Pak Global Technical Support AB (GTS) is a company within the Tetra Pak group which main task is to supply the whole world with spare parts for all kinds of Tetra Pak machines. GTS supplies about half a million different parts, which demands a large purchase organisation. This thesis deals with the so-called Sourcing purchase, which is a term for purchase of non-forecasted parts that have no
Elektromagnetiska vågor, även kända som radiovågor, är vågor som sprider sig med låga frekvenser från 3 till 30 kHz. Dessa lågfrekventa vågor används vanligtvis när man önskar kommunicera med ubåtar. De kan emellertid också användas på land för att mäta skillnader i jord– och bergarters elektriska konduktivitet. Denna mätteknik kallas Very-Low-Frequency Electromagnetics (VLF-EM) och har framgångsrElectromagnetic waves, also known as radio waves, which propagate at low frequencies of only 3 kHz to 30 kHz, are usually used for communication with submarines. However, these waves can also be used on land to measure differences in the electrical conductivity of the subsurface. This technique is called Very-Low-Frequency Electromagnetics (VLF-EM) and has been successfully used to gain an insight
Reliable methods for estimating financial return volatility are crucial in many areas of trading and investing. Two such frameworks, the GARCH and SV, have been of particular interest to academics and practitioners alike. The GARCH model describes the variance of the current innovation as a function of the actual sizes of the previous innovations. In contrast, the stochastic volatility model descr
This thesis investigates a new type of Phase-Locked Loop (PLL) architecture which combines a phase/frequency detector (PFD) and a digital loop filter. The quantization is done by a time-to-digital converter which continuously shrinks the pulse coming from the PFD and registers how far it propagates. Based on how far into the TDC each pulse propagates, the phase error is determined. The design is f
The objective of this study was to create a superhydrophobic surface using polymers that are non-fluorinated and applying them to a surface via rapid expansion of a supercritical solution (RESS). Solubility studies of poly(epsilon-caprolactone) (PCL) and a statistical copolymer of vinyl acetate and vinyl pivalate (P(VAc-VPi))in supercritical carbon dioxide (scCO(2)) were carried out using an extra
The production of non-prompt D0 mesons from beauty-hadron decays was measured at midrapidity (|y| < 0.5) in Pb-Pb collisions at a nucleon-nucleon center-of-mass energy of sNN = 5.02 TeV with the ALICE experiment at the LHC. Their nuclear modification factor (RAA), measured for the first time down to pT = 1 GeV/c in the 0–10% and 30–50% centrality classes, indicates a significant suppression, up to
Ever-increasing global water shortages necessitate more advanced and cost-effective water purification methods. Herein, a novel slow filtration system using natural raw zeolite is proposed as an alternative to traditional quartz sand as a filter medium. The system demonstrates excellent performance in reducing turbidity and removing methylene blue (MB). The natural zeolite-based filtration system
Non-traditional stable isotope systems are increasingly used to study micronutrient cycling and acquisition in terrestrial ecosystems. We previously proposed for zinc (Zn) a conceptual model linking observed isotope signatures and fractionations to biogeochemical processes occurring in the rice soil environment and we suggested that 2’deoxymugineic acid (DMA) could play an important role for rice
We celebrate Certec’s 20th birthday . . . . . . by giving you a book of 20 important ideas filled with pictures and text. Each idea is expressed in a succinct heading that sums up what we have learned over the years. The ideas also act as a complement to all the reports, website cover pages, brochures, lectures and annual reports. There are 30,000 documents at www.certec.lth.se that provide the
In order to stimulate benchmarking and comparisons between different municipal activities, the Swedish Association of Local Authorities and Regions (SALAR) and the Ministry of Finance in the year of 2007 initiated a voluntary nationwide Swedish benchmarking project (NBP) in order to develop new measures that capture the relationship between cost and quality. The ambition is that the new measures s
Popular Abstract in English Freezing is a commonly used method of preserving food products including fruits and vegetables. A fresh-like texture and appealing visual appearance of frozen and thawed plant food products are of key importance for customer acceptance. Therefore, the food industry is constantly looking for ways to improve freezing techniques, especially for sensitive plant tissues suchFreezing is a widely used method of preserving food products. Efforts are currently being directed towards improving the quality of the sensitive tissues of plant foods such as leaves, after freezing and thawing. One of the methods under investigation is the combination of vacuum impregnation (VI) with cryoprotectants and the application of a pulsed electric field (PEF) to the plant tissue prior t
Popular Abstract in Swedish Insulinberoende diabetes mellitus (IDDM = Typ 1 diabetes), och kronisk sköldkörtelinflammation - autoimmun thyreoidit (AIT) anses idag vara orsakade av att de hormonproducerande cellerna angrips av kroppens eget immunsystem (sk. autoimmunitet). När sjukdomen ger sig till känna kliniskt finnes antikroppar (sk. autoantikroppar) riktade mot cellkomponenter i det hormonprodThe two most common autoimmune endocrine diseases in children are autoimmune thyroiditis (AIT) and Type 1 (insulin-dependent) diabetes mellitus (IDDM). Autoantibodies (ab) can be found several years before clinical diagnosis in both diseases. The aims of this study were to investigate the prevalence of thyroid ab in children with IDDM and in children with allergic diseases; to study islet ab and t
The extraction procedure for analysis of the raffinose family oligosaccharides (RFOs) in blanched leguminous vine peas was optimized. For this purpose, 25 pea samples from different cultivars and of different maturity were chosen at random. The effect of blanching was also studied in four cultivars. The yield of oligosaccharides was almost double on average when extracted with 50% ethanol as compa
Atmospheric aerosol particles serving as cloud condensation nuclei (CCN) are key elements of the hydrological cycle and climate. We have measured and characterized CCN at water vapor supersaturations in the range of S=0.10-0.82% in pristine tropical rainforest air during the AMAZE-08 campaign in central Amazonia. The effective hygroscopicity parameters describing the influence of chemical composit
Popular Abstract in Swedish Tvärsektoriella nätverk mellan myndigheter, näringsliv och olika intressegrupper har tilldelats en allt större betydelse, då det varit en vanlig uppfattning att en hållbar utveckling bäst skapas genom ett gemensamt ansvar. Uppfattningarna om resultaten av dessa initiativ uppvisar dock spektakulära skillnader: från att framstå som oslagbara lösningar på de utmaningar soThe importance of cross-sectoral collaborative initiatives, that is partnerships of governments, civil society and the private sector, was elevated due to the belief that the issues of SD are a collective responsibility of all societal actors. The assessment of these initiatives is ranging dramatically; from giving them a status of an unbeatable solution for the SD challenges, to blaming them for
Fluorescence recovery after photobleaching, FRAP, has been an established technique of quantifying the mobility of molecular species in cells and cell membranes for more than 30 years. However, under non-ideal experimental conditions the current methods of analysis still suffer from occasional problems, for example, when the signal to noise ratio is low, when there are temporal fluctuations in the
