Background: Dosimetry in radionuclide therapy often requires the calculation of average absorbed doses within and between spatial regions, for example, for voxel-based dosimetry methods, for paired organs, or across multiple tumors. Formation of such averages can be made in different ways, starting from different definitions. Purpose: The aim of this study is to formally specify different averagin

Soil erosion vulnerability and extreme rainfall characteristics over the Mediterranean semi-arid region of Tunisia are crucial input for estimation of siltation rate in artificial reservoirs. A comprehensive high-resolution database on erosive rainfall, together with siltation records for 28 small reservoirs, were analysed for this region, the Tunisian Dorsal (the easternmost part of the Atlas Mou
The nuclear equation of state (EOS) is probed from statistical parameters, determined in an excitation function experiment on p + Xe-nat reactions at 200-1400 MeV. Total charge (Z) distributions follow a cascade-[multi]fragmentation-evaporation (CFEM) model well. The caloric curve in regions supposedly dominated by fast processes is compatible with a pure statistical multifragmentation (SMM) proce
This thesis was initiated with Toyota Material Handling Europe. The aim of the project was to find a business area in the world of material handling, and develop a conceptual design fulfilling the material handling need. Stepping outside of what is considered conventional material handling, I looked for a new context within consumer trends and future predictions. I found a correlation between th

Cancer är en otrevlig sjukdom, som drabbar många människor. Man söker ständigt nya och bättre sätt att bota patienter eller åtminstone lindra sjukdomens framfart. Ett vanligt sätt att behandla cancer är med strålning. Strålningen kan bestå av sk fotoner. Fotoner är samma slags partiklar som t.ex. vanligt ljus. Skillnaden är att de fotoner som används vid strålbehandling av cancer har högre energi "Purpose: The aim of this study was to investigate whether inversely planned intensity modulated radiation therapy (IMRT), using the clinical radiotherapy equipment at hand in our department, renders any advantages regarding dose distribution over conventional radiotherapy for head and neck cancer patients in the ARTSCAN (Accelerated RadioTherapy of Squamous cell Carcinoma in the head And Nec
The principal objective for this licentiate thesis is to develop a methodology and evaluation model in order to make the future relative humidity in a screeded concrete slab predictable. Residual moisture in screeded concrete slabs may redistribute to the top screed surface under semi-permeable flooring, thus elevating the relative humidity, RH, and possibly exceed the critical humidity level. Pas
Varje år sker företagsöverlåtelser för betydande värden. Företagsförvärv kan skapa stora värden, men det innebär även ett risktagande som kan leda till stora ekonomiska förluster. Ett av flera sätt som parterna kan påverka riskfördelningen mellan varandra är genom garantier. Genom att använda sig av formuleringen ”såvitt säljaren vet”, det vill säga en subjektiv garanti, kan säljaren minska det riEvery year mergers and acquisitions of significant value take place. An acquisition can create a large amount of wealth. However, it also involves taking risks, which can create big economic losses. One of many ways that the involved parties can affect the risk distribution between the parties is by using guarantees. By using the wording ”as far as the seller knows”, i.e. a subjective guarantee, t
Type Ia Supernovae (SNe Ia) are considered the most reliable standard candles and they have played an invaluable role in cosmology since the discovery of the Universe's accelerated expansion. During the last decades, the SNe Ia samples have been improved in number, redshift coverage, calibration methodology, and systematics treatment. These efforts led to the most recent “Pantheon” (2018) and “Pan
The relatively new combustion concept known as partially premixed combustion (PPC) has high efficiency and low emissions. However, there are still challenges when it comes to fully understanding and implementing PPC. Thus a predictive combustion tool was used to gain further insight into the combustion process in late cycle mixing. The modeling tool is a stochastic reactor model (SRM) based on pro
Wildfires are a major driver of ecosystem development and contributor to carbon emissions in boreal forests. We analyzed the contribution of fires of different fire size classes to the total burned area and suggest a novel fire characteristic, the characteristic fire size, i.e., the fire size class with the highest contribution to the burned area, its relation to bioclimatic conditions, and intra-
We report a comprehensive characterization of the multi-layered flame structure of a burning aluminum (Al) droplet in steam, using a novel spatiotemporally resolved laser absorption imaging technique combined with detailed numerical simulations. Spatial distributions of Al vapor mole fraction in the near-surface region (r/R0 < 1.2, R0: droplet radius) are quantified by accounting for resonance bro
Begreppet due diligence är i svenskt näringsliv synonymt med företagsbesiktning. Som företeelse är det en procedur för att genomlysa ett målbolags ekonomiska ställning och andra förhållanden. Företagsbesiktningen är således ett viktigt instrument för att skaffa sig kunskap om inneboende risker i målbolaget samt för att identifiera risker med förvärvet i stort. Besiktningen ger köparen ett bra beslThe concept of due diligence in the Swedish business sector is synonymous with "company inspection." It is legitimately a procedure for examining the financial position and other circumstances of a company. The company inspection is a significant instrument for acquiring knowledge of inherent risks in the offeree company, and for identifying risks with the acquisition in general. The con
