Introduction: The main route of excretion of activity for most administered radiopharmaceuticals is via the urinary bladder and it is important to estimate the absorbed dose to the mucosal surface of the bladder wall, especially when radiopharmaceuticals are given for therapeutic purposes. The purpose of this thesis was to investigate how the absorbed dose varies with changes in the parameters, wh

In this thesis, the phonetics and the phonology of non-modal voice quality and other glottal features in Chichimeco (Oto-Manguean, Mexico) are described. For this investigation, I analysed recordings I made in Mexico in spring 2017 as well as recordings enclosed in Lastra (2009b, 2016). Descriptions of this language have been published since the 1930s but non-modal phonation has not received the

K¨anslighetsanalys av barri¨aroptioner med algoritmisk derivering F¨or att f˚a ut optionspris och derivator p˚a priset med avseende p˚a tex r¨anta och volatilitet, utf¨ors vanligtvis ett antal simuleringar varp˚a ett medelv¨arde r¨aknas ut. D¨arefter r¨aknas derivatorna ut med en finit differensmetod. F¨or att erh˚alla tillf¨orlitliga resultat med denna metod kr¨avs ett stort antal simuleringar viAutomatic Differentiation (AD) is an effective method for calculation of derivatives. It can evaluate an unlimited number of derivatives to a fixed cost relative to the computing time of the original function. The AD technique is used in many fields for large and complex calculations in order to get accurate values of derivatives fast. Banks and other financial institutions handle calculations of

Crude oil is the most traded energy commodity in the world, and its price has a large impact on the everyday life of billions. Given the volatility of crude oil prices and its enormous effects on economies worldwide, there has been a growing demand for risk quantification and risk management for the market participants. The measurement known as Value-at-Risk (VaR) has become the industry standard

Background: The benefit of surgical resection for colorectal cancer (CRC) lung metastases is unclear. The aim was to investigate the incidence, treatment strategy, and 5-year overall survival (OS) in CRC patients with isolated lung metastases. Methods: This registry-based retrospective cohort study included patients treated with curative resection of CRC within the county of Skåne during the perio

Objective: To investigate whether pT1 renal cell carcinoma (RCC) should be followed differently after partial (PN) or radical nephrectomy (RN) based on a retrospective analysis of a multicentre database (RECUR). Subjects: A retrospective study was conducted in 3380 patients treated for nonmetastatic RCC between January 2006 and December 2011 across 15 centres from 10 countries, as part of the RECU

Process-based forest models combine biological, physical, and chemical process understanding to simulate forest dynamics as an emergent property of the system. As such, they are valuable tools to investigate the effects of climate change on forest ecosystems. Specifically, they allow testing of hypotheses regarding long-term ecosystem dynamics and provide means to assess the impacts of climate sce

Aim: The aim was to identify the primary drivers of compositional change in breeding bird assemblages over a 40-year period. Location: Britain. Time period: From 1970 to 2010. Major taxa studied: Birds. Methods: Using morphological trait measurements and a dataset of presence–absence data for British breeding birds surveyed in 10 km × 10 km hectads during two time periods, we calculated temporal t

The three mechanisms that describe the reaction kinetics for various combustion processes were evaluated against experimental data for a reforming process. M1 is the GRI-Mech 3.0 mechanism, originally designed to model combustion of natural gas. The M2 mechanism originated from a methane combustion mechanism, which was extended to include reactions for methanol, acetaldehyde, ethanol, and ethylene

This article traces how African incomes have been measured through history, and shows that there has been a conflict of aims between producers and users of national income estimates. Politicians and international organizations seek income measures that reflect current political and economic priorities and achievements. Thus the importance given to markets, the state, and peasants in the estimates

This thesis aims to explore how specific digital field recording methods impact archaeological interpretation based on the case studies presented. Individual find recording, a more specialized digital point proveniencing system, was used in both case studies. The original excavation interpretations are compared against new interpretations based on the reconstructed excavation unit style recording

Abstract The purpose of this essay was to study the parental education for adoptive parents. It´s provided by law since 1/1-2005 that parents have to participate in this education-program before they adopt. We wanted to look at what caused the change and made the education compulsory and to find out where the initiative came from, what purpose the education is supposed to fulfil, if it can facili

Model predictive control can be used to control a range of processes, from selfdriving cars to chemical plants. The education of the engineering students that in the future will design these controllers is an important matter. In this thesis, three Matlab toolboxes have been evaluated and compared from a student’s perspective. The toolboxes are Mathwork’s own toolbox called Model Predictive Contro

This work was performed to quantify the performance of extracts and saponins in residues generated by exporters of quinoa in the departments of La Paz, Oruro and Potosi, determining that the extraction yields range from 36.0 % to 39.4 % w/w, while the percentage of saponins in the extract ranged from 47.3 % to 56.2 % and saponins in the residues from 17.3 % to 22.1 %. Additionally, a method was op

Results are presented from data recorded in 2009 by the PHENIX experiment at the Relativistic Heavy Ion Collider for the double-longitudinal spin asymmetry, A(LL), for pi(0) and eta production in root s = 200 GeV polarized p + p collisions. Comparison of the pi(0) results with different theory expectations based on fits of other published data showed a preference for small positive values of gluon
