OBJECTIVE: Recent in vivo results have shown prominent tissue sparing effect of radiotherapy with ultra-high dose rates (FLASH) compared to conventional dose rates (CONV). Oxygen depletion has been proposed as the underlying mechanism, but in vitro data to support this have been lacking. The aim of the current study was to compare FLASH to CONV irradiation under different oxygen concentrations in
The aim of this study was an in-depth investigation of the change process experienced by patients undergoing bariatric surgery. A prospective interview study was performed prior to as well as 1 and 2 years after surgery. Data analyses of the transcribed interviews were performed by means of the Grounded Theory method. A core category was identified: Wishing for deburdening through a sustainable co
This study aims to examine the effectiveness of the narrative tools in the modern Arabic poetry and take Al-baradony poetry as a model because it is a fertile field for academic studies and is as diverse as the curriculum to be studied by way of applications It has been studied in some respects and is still under taken for reasons. This study tries to examine the phenomenon of narrative style Al-b
We show that Earth’s sedimentary strata can provide a record of the collisional evolution of the asteroid belt. From 1652 kg of pelagic Maiolica limestone of Berriasian–Hauterivian age from Italy, we recovered 108 extraterrestrial spinel grains (32–250 μm) representing relict minerals from coarse micrometeorites. Elemental and three oxygen isotope analyses were used to characterize the grains, pro
In her dissertation Aspektuella hjälpverb i svenskan, Maria Bylin investigates the evolution of six aspectual auxiliaries in Swedish (bruka ‘use to’, tendera ‘tend to’, börja ‘begin’, fortsätta ‘continue’, sluta ‘stop’ and hota ‘threaten’). The study is conducted within the framework of grammaticalization, and Bylin’s primary method is to apply so-called auxiliary tests on a historical material co
In order to obtain more detailed characteristics and information in highly turbulent flames, for a better understanding of the transient behavior of eddies in such flames, a measurement technique with sufficient temporal resolution is requested. However, the probing of species distributions relevant in combustion (e.g. OH, CH2O) with ultra-high-speed laser diagnostics still remains a challenge. Nd
Oppositional pre-electoral coalition formation has, in a number of recent studies, been proven to have an important effect on the prospects for liberalizing electoral outcomes in authoritarian elections. Despite this recent recognition of oppositional coalitions as a trigger for democratization, almost nothing is known about when these coalitions are formed. An important explanation for the la
Electric and magnetic current densities are an essential part of electromagnetic theory. The goal of the present paper is to define and investigate stored energies that are valid for structures that can support both electric and magnetic current densities. Stored energies normalized with the dissipated power give us the Q factor, or antenna Q, for the structure. Lower bounds of the Q factor provid
On the decision of the Swedish government, the Swedish National Road Administration (SNRA) has started a large-scale trial with Intelligent Speed Adaptation (ISA) in urban areas. One of the four test sites is the city of Lund. At the Department of Technology and Society, Lund University, research about ISA has been carried out since 1986 and the first field study was carried out in 1993. The ongoi
Purpose Purpose of this paper is to explore and classify pattern of the currently discussed themes and challenges in making supply chains socially sustainable. Design/methodology/approach The methodology was based on a systematic review of the existing literature in order to explore what major themes and challenges have been discussed as well as the significant gaps where opportunities for furthe
This paper aims to describe the brownboard tool and to elaborate on its characteristics. Brownboard can be seen as a tool within process mapping and it is focused on supply chain traceability. The process map is created in a dynamical group process where supply chain actors with different competence level meet and interact. The brownboard tool is used in a case study based on a Swedish supply cha
Parallel trade in the pharmaceutical industry is a complicated issue because it has connections with competition law, trade law, and intellectual property law. International exhaustion benefits consumers by promoting price competition. This is an extremely attractive argument. For several years, the parallel trade in pharmaceutical products has been an important issue for the European pharmaceutic
This thesis touches upon and considers the relation between a person, state, and access to rights, with international freedom of movement as a vanguard. As movement is inherent in humans and allows us to search for other standards of living it is somehow central in this thesis. In relation to access to rights moving, across borders touches upon several issues, for example what is required of a per
There are today about 200 000 children living in families where either one or both parents are addicted to alcohol. These children often become young carers, as they are prematurely being placed in adult caring roles. The aim of this thesis has been to illustrate the situation for children of alcoholics and to examine how these children are coping when parents do not fulfil their parenting respons
Poverty reduction, first on the list of Millennium Development Goals, requires access to modernized, stable energy to be realized. Rural areas are especially vulnerable, which is why renewable energy technologies (RETs) illustrate a promising solution for modernized energy access. Entrepreneurs play an important role in these sustainable development projects by helping build up an entire sector of
In Nicaragua, one girl out of four at the age of 17 has experienced her first pregnancy. With such a high frequency, adolescent pregnancy is a social issue, and contradictory messages are given to teenagers by influencing elements such as the family, the culture, the Catholic Church, school and Centro de Salud, the health centres. The aim of this study was to provide a situation analysis of how ad
This thesis examines queer community archives (QCAs) and their governing documents in order to gain a better understanding of how they define themselves, their work, and the communities they serve. Focusing on archives associated with queer, leather, BDSM, and fetish communities, specifically The Queer Movement Archives and Library (QRAB) and the Leather Archives & Museum (LA&M), it examin
A year after the establishment of the protest camp Palestinagård at Lund’s University in May 2024 and its demolishment by the authorities, the student solidarity movement is continuously engaged in endeavours to get into conversations with the institutions at Lunds University to make their demands heard, as the genocide on the Palestinian population in Gaza is still ongoing. Further, Palestinagård
Unseen Sights: Magic, Modernity, and Childhood in Children’s Urban Fantasy explores and analyses the genre of children’s urban fantasy. Drawing upon a combination of fantasy, urban fantasy, and children’s literature scholarship, the thesis considers how children’s urban fantasy works – investigating both its forms and functions, and how it performs work in the world.The genre is analysed both sync
A numerical and experimental study of partial admission in a low reaction two-stage axial air test turbine is performed in this paper. In order to model one part load configuration, corresponding to zero flow in one of the admission arcs, the inlet was blocked at one segmental arc, at the leading edge of the first stage guide vanes. Due to the unsymmetrical geometry, the full annulus of the turbin
