Background and purposeDeep inspiration breath hold (DIBH) increases lung volume and can potentially reduce treatment-related toxicity in locally advanced lung cancer. We estimated geometric uncertainties in visually guided voluntary DIBH and derived the appropriate treatment margins for different image-guidance strategies.Material and methodsSeventeen patients were included prospectively. An optic

In the purple phototrophic bacterium Rhodobacter sphaeroides, light harvesting LH2 complexes transfer absorbed solar energy to RC-LH1-PufX core complexes, which are mainly found in the dimeric state. Many other purple phototrophs have monomeric core complexes and the basis for requiring dimeric cores is not fully established, so we analysed strains of Rba. sphaeroides that contain either native di

We obtain large n asymptotics for the m-point moment generating function of the disk counting statistics of the Mittag-Leffler ensemble, where n is the number of points of the process and m is arbitrary but fixed. We focus on the critical regime where all disk boundaries are merging at speed n − 1 2 , either in the bulk or at the edge. As corollaries, we obtain two central limit theorems and preci

Compositionally graded channel AlGaN/GaN high electron mobility transistors (HEMTs) offer a promising route to improve device linearity, which is necessary for low-noise radio-frequency amplifiers. In this work, we demonstrate different grading profiles of a 10-nm-thick AlxGa1-xN channel from x = 0 to x = 0.1 using hot-wall metal-organic chemical vapor deposition (MOCVD). The growth process is dev

The advent and popularity of shared electric scooters in many urban areas worldwide offer new opportunities and challenges to be addressed by the research community, especially as far as safety and accessibility issues are concerned. This paper proposes a methodology, based on geofencing technology (i.e., virtual geographic boundaries) to define in which urban areas the speed of shared electric sc

Reducing the excitation threshold to minimize the Joule heating is critical for the realization of perovskite laser diodes. Although bound excitons are promising for low threshold laser, how to generate them at room temperature for laser applications is still unclear in quasi-2D perovskite-based devices. In this work, via engineering quasi-2D perovskite PEA2(CH3NH3)n-1PbnBr3n+1 microscopic grains

Background: PET/CT may be more helpful than CT alone for radiation therapy planning, but the added risk due to higher doses of ionizing radiation is unknown. Objective: To estimate the risk of cancer induction and mortality attributable to the [F-18]2-fluoro-2-deoxyglucose (FDG) PET and CT scans used for radiation therapy planning in children with cancer, and compare to the risks attributable to t

Recent advances in therapeutics are now providing a wide range of options for adults and children living with hemophilia. Although therapeutic choices are also increasing for the youngest individuals with severe disease, challenges remain about early management decisions, as supporting data are currently limited. Parents and healthcare professionals are tasked with helping children achieve an incl

Responsible internationalization has become an increasingly used term to promote relationship building in a world which is increasingly shaped by the growing impact of global challenges and geopolitical competition. Amidst these changing global conditions researchers and universities have started to learn that they need to adhere to an expanded set of norms related to the research endeavor. Today

Wine is an important cultural crop and is grown in vineyards that sometimes claim to have a unique "terroir" - a specific taste and character based on their physical attributes and location. Regulations and previously published work are not easily available, into how to measure and assess this terroir. It is important for countries such as Sweden to have a terroir assessment system, whic

Globally, 500 million smallholder farmers require finance to secure a more productive, efficient, sustainable, and inclusive food system. Thus far, traditional financial services have been unsuccessful in reaching these farmers. Yet, mobile money services are proposed as a potential tool for enabling smallholder farmers access to financial services. Nonetheless, this proposed impact of mobile mone

Since the boom in global food prices in 2008, governments and companies around the world seek to boost agricultural output and sustain internal food security through the purchase and lease of farmland in Sub-Saharan Africa. There is no consensus in the literature whether land acquisitions by foreign investors are beneficial to the livelihoods of the local people in Africa. This thesis aims to cont

Collimated Transmission Spectroscopy (CTS) is a technique that is commonly used to study the optical absorption of different media. In this work CTS was used to measure the absorbance of pure raspberry juice in order to investigate how well the fruit content may be determined in a commercially available raspberry fruit drink. Another method, RGB colorimetry, which is a much more available techniqu

The world continues to be shaped by crises in both new and familiar forms. International and non-international armed conflicts and disasters are barriers to individual wellbeing, development, stability, and in the case of the former, represent a basic challenge to peace. The aftermath of such crises, in which communities can be rebuilt and the fabric of society can be mended, can be a time for rec

In this thesis the heating area of a belt furnace for annealing metal powder has been modeled. The model was extended with PI-controllers for controlling the energy added to the model. It was simulated with differently tuned controllers to test tuning principles for finding suitable control parameters for the process. The most promising tuning principles was then written as a manual with the aim f

Since the introduction of Edison’s lightbulb over one-hundred years ago, humanity has struggled to keep up with electrification for all. With global attention now aimed at sustainable energy production, the struggle becomes more complex by not only obliging energy access, but access to clean energy. The concept of microgrids has been promising for filling in the demand, but not quickly enough to m

Neonicotinoid insecticides are agonists to nicotinic acetylcholine receptors (nAChRs) in the brains of insects. At sub-lethal doses these chemicals cause behavioral abnormalities in several bee species, reducing overall fitness. nAChRs expressed in the optic lobes of insects bind neonicotinoids, thus may be involved in these behavioral changes. Here we attempted without success to visualize the pr
